How to make a herb chopper with your own hands: subtleties, diagram, safety

Features of making a garden shredder with your own hands

To produce a shredder you will need certain equipment. Be sure to have an old case with a working electric motor; it could be from a washing machine, vacuum cleaner or other household appliances that you wanted to throw away. Be sure to get additional parts, purchase fastening components, as well as knives and gaskets. Make sure you have a container where the finished fertilizer will go. It is convenient if you make grinding equipment that is as tall as you are, but legs will be useful for this (wooden and metal are suitable).

Be careful! The grass and straw chopper works like a food processor, so do not put your hands into the device while it is running.

When working with an electric motor, namely when soldering it and attaching additional components to it, follow safety rules.

The nuances of operating homemade equipment

A self-made shredder is essentially three in one: a chopper for branches, a straw cutter, and a mechanism for cutting grass. It helps to significantly facilitate household work associated with the disposal of plant waste, as well as feeding poultry and livestock.

For homemade electrical equipment, it is recommended to install a separate differential circuit breaker to provide reliable protection against electric shock in case of unforeseen circumstances. In any case, when making a garden shredder yourself, you must follow safety regulations. It is also worth adhering to them during operation of the mechanism. Before working with equipment, it is recommended to wear goggles, suitable protective clothing and check that the structural elements are securely fastened. When creating a home-made unit, you should take into account the upcoming amount of work, as well as the nature of the vegetation being processed, in order to select an engine of the required power and the desired design of knives. This will allow the completed device to cope with the assigned tasks without any problems.

How to make a grass grinder from a washing machine with your own hands: a detailed guide

You can buy a grass cutter at your own discretion in professional retail outlets, but when you have a tank from an old washing machine at hand, and you have the appropriate available equipment in the shed, you can not spend money on equipment, but make it yourself.

Preparatory stage: assembly of tools and components

The basis of the shredder for grass and small branches will be a housing with an engine from household appliances of the last century. Remember that for proper production you need to use a motor with a power of at least 180 W, running at about 1400 rpm. You will also find it useful:

• a hacksaw (we will cut knives from it for processing natural materials) or a circular knife;
• an electrical cable of sufficient length with a plug (3?4 meters);
• fasteners, metal square;
• locksmith kit;
• grinder, drill;
• welding machine and skill in working with it.

It is better to use a disk knife as a knife for homemade grass cutters. Its operation has already been tested by many, and it does an excellent job of chopping even branches of small diameter.

When connecting all parts using mechanical fasteners, it is necessary to use rubber gaskets or washers to ensure the tightness of the connection.

Assembling the body and introducing working parts

We begin assembling the device by preparing the case:

1. To do this, we cut off the excess height of the tank with a grinder to the optimal size. Approximately the height of the container where you will throw the grass should be no more than 60 cm.
2. A cover or rubber casing is needed on the top hole to prevent grass from flying out. If desired, it can be cut out of dense rubber of the appropriate diameter and attached with bolts, fixing them on the side of the body.
3. Next, we take a metal corner, cut it and make it approximately 50 cm long. We drill side holes on it where the legs will be attached.
4. Now we attach the disc knives to the axle, you can install them in several rows (2? 3), fasten them with bolts

5. If you do not know how to use a lathe, then order the bushing from a professional, otherwise there is a danger of injury
6. We make a bushing for the engine. It should have two 7mm holes with a thread at the end. Remember that the size of this part should be no more than 50 mm.
7. Accordingly, we make two 7 mm holes on the motor shaft, after which the bushing is fastened to the motor using bolts.
8. We turn our body upside down. This is where we will mount the engine. For this procedure we will need long hairpins. To do this, make two or three holes in the housing (depending on the number of latches).
9. We put prepared, well-sharpened knives on the sleeve and secure them with nuts. Check that the tips of the knives do not touch the inside of the body and do not dangle, that is, they are securely fastened.

10. Incorrect connection of the knives during operation will be accompanied by noise and vibration, and the body will be noticeably deformed
11. Next, we correctly connect the electric cable to the contacts of the electric motor (note that the insulation of the conductors must be the same color). Additionally, we insulate the connections with electrical tape or special silicone tubes. Look at the diagram below to see how the motor should be connected correctly.

12. Connection diagram of the engine to the electrical network
13. Cut a hole to release the crushed raw materials. Remember that it should be placed several centimeters below the installation of the knives.
14. The finishing touch is organizing the stand. If you do not have the opportunity to connect the legs to the metal axle, then weld a large diameter metal circle to it.

Take care in advance about the presence of grounding for this unit, since when turned on, it will take a lot of power onto itself, which entails a malfunction of household appliances in the house.

The container for receiving treated grass can be a regular tank, box or bucket

How to assemble a cutting element yourself

To make a milling knife you will need:

• circular saws (10-12 pcs.). Their quantity may differ from the indicated amount, both smaller and larger. The more disks are installed, the smaller the chips will be at the output;
• threaded rod M20;
• bearings (internal Ø 20 mm);
• dense soft plastic for making spacer washers;
• washers and nuts for fastening.

1. Place the disk on the pin (its diameter of 20 mm coincides with the hole of the saws).
2. A washer cut out of plastic should be installed between adjacent disks. It is necessary so that the cutting edges of adjacent saws (they are wider than the blade of the blade) do not cling to one another.
3. The outer disks are secured with washers and nuts. As a result, you will get a shaft with circular saw blades located on it. All that remains is to install the bar with saws on the frame using bearings, bushings and clamps.

Additional shredder options: production instructions

You already understand that a herb chopper is a device similar to a food processor; accordingly, it can also be made mechanically, for example, from electrical tools available on the farm: a drill, an angle grinder and an old vacuum cleaner.

A drill grinder is a primitive and affordable device

The drill motor for the chopper must be high-speed, otherwise there will be no effective processing

To build such a device, you will need an ordinary, but quite powerful drill, circular or flat knives connected into one unit with a bolt, as well as an attachment for an electrical appliance. Before use, the attachment is attached to the drill socket, then the knives are fixed to it. Place the prepared grass in a deep container, lower the drill and start it. Hold the installation so that during movement the knives do not touch the container where all natural material is collected.

Homemade grass grinder from a grinder

From an angle grinder you can make a compact, practical, but not very productive device

Regardless of what the homemade shredder is made of, the principle of its operation is similar to any electric motor. Accordingly, a device made from an angle grinder will be no different from a professional one if it is assembled correctly. For this product you will need a special hopper or a metal case from any device, a protective cover, and a grass cutter with a motor.

To produce a grass grinder, it is better to use special knives that are sold in stores. And if you plan to make it yourself, take a metal plate with one edge sharpened.

Scheme for making a herbal grinder from a vacuum cleaner

Pay attention to the diagram of how the parts should be selected

The use of a Typhoon type vacuum cleaner engine guarantees greater performance than previous devices. The principle of operation of the device is to supply greens through the top hole, and the output of the finished material? through the bottom. Remember that the stand for the unit should not be too high, otherwise the grass will scatter to the sides during processing. The leading role for this will be played by the protective casing for both holes.

Apparatus from a household cultivator

The device, made on the basis of a drive from a cultivator, is similar in design to a crusher made from a drill. The device has increased productivity and allows you to simultaneously process a significant amount of grass. In the process of assembling the grass cutter, the following is used:

1. Cultivator drive;
2. Knife made of hacksaw blade;
3. Bushing for attaching the knife;
4. Self-tapping screws;
5. Capacity;
6. Tabletop;
7. Frame for tabletop.

After securing the drive to the table top with a hole for the motor, using self-tapping screws and staples, you need to fix the mechanism casing to the block. A funnel from a drain can be used as a socket; the entire assembled structure is installed and secured on the table. To prevent the tabletop with the device from slipping due to vibration, it is recommended to install limiters.

DIY hay chopper design

Large farms or livestock production cannot do without a hay chopper. Changing this arrangement helps rationally distribute hay and straw for livestock. If you do not plan to buy such a unit, but want to build it yourself, it is important to remember what is included in the design:

1. Electric motor. You can choose the power of the installation yourself, but remember. The higher the consumption rate, the more productive the device will be.
2. The body is the basis of the hay chopper. Choose a diameter such that the knives do not come into contact with the walls.
3. Shaft with knives . Fixed knives must be made of durable steel and well sharpened.
4. Receiving container for finished raw materials . It is better to position it relative to the body at an angle.
5. Supports and stands . The ideal implementation of this part of the device is made of metal pipes with a diameter of up to 25 mm.

Which motor should I get?

It is more convenient to work with old washing machines - Oka and Fairy are ideal. Top-loading barrel-shaped models with a bottom-mounted motor are easy to transport.

Expert opinion

Vladislav Ponomarev

Design engineer, inventor

A suitable motor has the following characteristics - power 180 W, engine speed 1350-1420 rpm.

Fairy models have a centrifuge, so the motor makes more revolutions, up to 2850 per minute, but the power is lower. The body is plastic and fragile. From Fairy models they take only the engine, the tank is made from an empty iron barrel, and knives are purchased additionally.

The advantages of having a unit are obvious - the ability to process any volume of grass in a short time. A grass cutter is needed not only by gardeners, but also by owners of subsidiary farms - ground green raw materials are added to food for livestock and poultry.

Corn stalk chopper: making your own device

To produce a corn stalk mill, you will need an electric motor with one or three phases, and its power must be at least 500 W. Below in the table we will look at how to assemble such a structure.

Approach the invention of the device responsibly, otherwise, instead of the desired result, you will get a bunch of torn, rather than finely chopped, grass.

Grass cutter from trimmer

A garden shredder can be made using a gasoline or electric trimmer. In this case, the tool will work in an upside-down position. To create equipment designed to chop grass and thin twigs, you will need, in addition to a brush cutter with cutting attachments, the following materials:

• plastic or metal container with a volume of at least 50 liters;
• approximately 1 sq.m. steel mesh with small mesh size;
• about 3 meters of metal tube (aluminum or steel) half an inch in diameter;
• a piece of board or moisture-resistant chipboard, plywood of such width that the trimmer fits on it;
• clamps that will attach the brush cutter to the wooden base;
• self-tapping screws, bolts, nuts, washers;
• wooden blocks (5 by 5 cm is enough).

To assemble a chopping mechanism from a trimmer, you will need to use the following tools and devices:

• a screwdriver or screwdriver with bits;
• electric drill with a set of drills for wood and metal;
• an electric jigsaw with files for cutting metal or a manual equivalent;
• hammer;
• open-end or socket wrenches;
• punch;
• an anvil or a flat iron plate.

A punch is needed to make it convenient to drill holes with an electric drill. This tool is pointed at the point where the metal needs to be drilled. Then it is hit with a hammer. The drill does not slip out of the resulting recess when drilling a metal part.

Preparatory activities

A grass cutter from a brush cutter is manufactured in a number of stages. Initially, they are prepared in a container where the grass and branches will be ground:

• make markings on the bottom (along the perimeter) for four trapezoidal holes with rounded corners;
• drill holes with a cross section of 1 cm in each drawn segment;
• a jigsaw file is inserted into them and trapezoids are cut out;
• process the cuts with a file or sandpaper;
• a hole is drilled in the center of the bottom for the chopper shaft;
• a circle is cut out of steel mesh with dimensions according to the diameter of the bottom;
• using small scraps of boards or blocks, the prepared mesh fragment is secured to the container from below;
• Legs for the container are made from metal tubes, attaching them to the tank with bolts.

The wooden pieces are fixed with self-tapping screws, twisting them from the inside of the tank into metal jumpers between the cut trapezoids. In this way, the mesh is securely attached to the bottom of the container.

The legs are made in the following way:

• bend the tubes in a vice or using a pipe bender in the shape of the letter “P”;
• the ends of future supports are flattened with a hammer;
• 2 holes are drilled into them on each side (6.5 or 8.5 mm cross-section);
• fit the workpieces to the bottom of the container and mark the points of bolted connections;
• drill according to the hole mark;
• using bolts with washers and nuts, attach to the footrest casing.

After preparing the casing, in order to reduce the dimensions of the created mechanism, the following operations are performed:

• disassemble the trimmer, disconnecting the motor, rod and cutting attachment from each other;
• cut off a fragment approximately 20-40 centimeters long from the rod with the cable;
• collect the lawn mower;
• check the performance of the equipment.

Chopper assembly

If the trimmer works well after assembly, then it is used to create a grass grinder.

1. The motor of the brush cutter is attached to the board with clamps.
2. Fix the bar on a wooden base using clamps and a handle from a brush cutter.
3. Connect the cutting attachment to the end of the rod, previously inserted into the hole at the bottom of the casing.
4. They start the mechanism and test it in operation.

After these steps, you will get a unit, the photograph of which is presented below.

If the trimmer used to assemble the shredder is equipped with a gasoline engine, then the motor is placed on the base so that it is convenient to fill in fuel, start the device and regulate its operation (speed).

Do-it-yourself crusher for branches and wood waste for home and garden: production technology

To manufacture this unit, it is imperative to have bearings and durable metal panels with a thickness of at least 20 mm in your arsenal of tools.

Any old working engine can be used for production

1. It is necessary to acquire a special engine with a power of 2.5–3.5 kW. If this indicator does not correspond to the specified range, you will not be able to split larger branches. A diesel engine can have a power of 5–6 liters. With.
2. Calculate so that your crusher operates at 1500 rpm. The developing torque is of great importance.
3. Pay attention to the dimensions of the drive pulley; its size should be no more than 100 mm, while the diameter of the driven pulley will be 200 m.

1. Pay attention to what pulleys for agricultural shredders should look like
2. Disc knives can be used as knives for crushing branches and small twigs. It is ideal to arrange them in groups on one shaft, see photo.

It is advisable to place the knives sequentially. This way they will create a more rigid cutter that can cope with crushing a whole bunch of twigs and branches

You can make knives for crushers yourself or order a part specifically for rotary propulsion devices. They meet the requirements of quality and rigidity.

Power units used

There are two types of devices for chopping branches:

• driven by an electric motor;
• powered by internal combustion engines.

For low-power homemade wood waste crushers, an electric motor is mainly used. This is explained by the fact that an engine running on gasoline or diesel fuel most often has more power than an electric one. For example, a scooter engine with a volume of 50 cm³ produces approximately 5 liters. With. or about 3.7 kW.

For infrequent grinding of garden waste, such a power unit is simply not necessary.
