Do-it-yourself mushroom cutting diagram

Do-it-yourself grass cutter driven by an angle grinder

I have birch trees growing in my dacha. Leaves are falling from the trees. We have to clean it up, burn it, and fill up the compost pit. The foliage takes a long time to rot. I decided to chop it up. For this you need a grass cutter. I looked at what they were making on the Internet. I turned on my brain and this is what I came up with.

Do you like an inexpensive option for a garden shredder? Read the article further and find out how to make a homemade product from an angle grinder and a metal tank. Tok2Z acted like this:

He thought about how to twist the chopper blades. The choice is small - install a motor from a washing machine, or buy an electric motor. According to the user, the motor from the washing machine is weak, and I didn’t want to purchase a three-phase unit and convert it to one phase.
Tok2Z bought on the market, for 2 thousand rubles, an old grinder with a power of 2 kW and blades from a lawn mower for 700 rubles. I ordered an adapter sleeve from a turner, spending another 500 rubles.
I welded the frame and placed a galvanized water tank on it. I assembled the structure and turned on the grass cutter.

The turnover is crazy. I threw a shovelful of leaves into the tank, and they blew away! I checked where the flow was going. Air goes up from the edge of the tank and is sucked in in the middle. I cut out a galvanized ring and installed it in the center of the tank. Threw the leaves. The knives crushed it just right, and it flew into the lower pipe.

To grind the grass into a very fine fraction, the user installed a corner in front of the “exhaust” pipe.

The grass cutter shreds the leaves directly into the compost bin.

Compare: a pile of leaves.

The grass cutter threshes everything - grass, leaves. Sometimes, along with the foliage, a wire comes across. Pebbles. Pieces of metal. The crusher crushes the stones. No iron. You have to turn it off, look for trash and throw it away. The noise is terrible. One of the disadvantages is the thin walls of the tank. It breaks through. I will redo it. I will make a tank from a sheet of iron 1-2 mm thick.

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.

If you have to process grass in small quantities, for example, for chickens, geese, ducks, then very simple devices that operate on human muscle power, for example, a hand pruner, are sufficient.

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.

Universal grass cutter and corn sheller

I also made a grass cutter. I mainly use it to chop grass for poultry. The basis of the homemade product is a kilowatt motor made in the USSR. I bought it for 1400 rubles. Works great. The engine is three-phase, but converted to operate from a 220 Volt network.

Making a homemade grass cutter step by step:

Holes were drilled and threaded in the flange.

The knives were made from a piece of an old rusty two-handed saw.

The knives were screwed to the flange.

The grass cutter frame was made from a sheet of metal 4 mm thick. A strip of metal with a cross-section of 4x40 mm was welded to the square, which was bent in a circle. A hole was drilled in the center of the frame.

I bent the strip with a hammer, striking the metal on the jaws of a vice. The radius was controlled in a circle by drawing it on the bed.

At the finish, the user welded the legs to the base. Fixed the electric motor. I made a large tank with a lid so that debris would not fly out of the grass cutter while the engine was running.

The tank is removable for ease of use of the grass chopper.

What should the wood chips be like?

Wood filler for wood concrete has its own GOST.
At the level of the state standard for wood chips, strict requirements are established. Three main parameters are identified:

length no more than 30 mm;
width no more than 10 mm;
thickness no more than 5 mm.

The optimal dimensions for width and length are also indicated:

length – 20 mm;
width – 5 mm.

New requirements appeared with the adoption of GOST 54854-2011. Before this, there was another GOST with lesser requirements. Then it was allowed to use longer chips - up to 40 mm. In 2022, “liberties” in the size of the filler are not allowed.

The standard also regulates the presence of impurities: bark, leaves, pine needles. The material should be cleared of soil, sand, clay, and in winter - from snow. The presence of mold and rot is unacceptable.

Corn husker from grass cutter

Alex Nk decided, based on a grass cutter, to make a mechanism for shelling corn. The result is a two-in-one unit. To make a homemade product you need:

Cut a disk out of metal.

Drill holes in it for M6 bolts.

Rework the base so that the outlet is at the bottom. This is how the grass is chopped finer, and the corn is not chopped.

The disk was screwed to the flange.

The tank has been redone. A “reflector” was attached to it to throw the corn “cobs” into the bucket.

Grass cutter-corn sheller assembled.

Places for storing fasteners.

To prevent the grass from wrapping around the motor shaft, the user installed a protection ring.

I found experimentally that the optimal option for chopping grass is two knives. Four knives turn the grass into mush. I also threshed apples for the poultry. One bucket of apples is crushed in 4-5 minutes. The result is a grass cutter-vegetable cutter-fruit cutter.

Equipment for cutting, cutting, shredding:

The equipment is designed to remove the center of apples and cut apples into rings, both functions are contained in one machine. The equipment is a semi-automatic machine; apples are fed manually and installed in special cells of the circular feeding conveyor. Next, the apples are fed into the working area of the machine, where the core is cut out, then the apples are cut into rings. The cut out center is dispensed through the outlet hole at the back of the machine, the finished product (pitted apples, cut into rings) is dispensed from the side of the machine through the outlet tray.

Such equipment is widely used by food production and agricultural enterprises for processing apples. The machine for removing the core and cutting apples into rings significantly speeds up the apple processing process and saves human labor. Ready apples cut into rings can be used to make compotes, canned fruit, jam, confectionery products and much more.

How to make a wood chipper

When pruning trees in winter, every gardener is faced with the problem of storing thin branches, since they take up quite a lot of space. You have to chop them manually or using a special chopper. The second option is preferable, as it makes it possible to process the wood into small chips very quickly. Only factory-made units are too expensive, and therefore in this article we will tell you how to make a branch chopper with your own hands much cheaper.

How to make a disc crusher?

If you like this type of chopper, then you need to understand that its assembly will require good welding skills. In addition, you need to prepare the following materials:

steel sheet with a thickness of 10 to 16 mm;
the same, 5 mm thick - on the casing and loading hopper;
high-carbon steel for knives, a car spring is suitable;
round or profile pipes to weld the frame;
steel shaft with a diameter of 20 mm;
2 rolling bearings No. 307 or others;
fasteners (bolts and nuts)
pulleys, belt.

Note. There is no need to install a belt drive if you plan to use an electric motor with a speed of 1500 per minute for the crusher.

On various Internet resources you can find all sorts of drawings of a wood chipper; we bring to your attention one of the popular options:

A regular circle with a diameter of 400 mm is cut out of thick metal, and a hole for the shaft is made in its center. The pulleys and shaft must be turned on a lathe, and threads must be cut at the ends of the shaft to attach the flywheel and pulley. Knives can be made at home, following the drawing; in extreme cases, entrust this task to a milling machine operator. Next, a protective casing with a hopper must be welded from a steel sheet, and cages for bearings with holes must be made from it.

In essence, a homemade wood chipper is a cutting mechanism mounted on a frame of any design. The drive motor can be placed in a convenient location depending on the length of the belt. Do not forget to make the engine mount sliding so that the belt can be tensioned. The mechanism shaft is also installed on the frame, and a pulley and flywheel are attached to it. The knives should be bolted to the flywheel so that their angle of inclination is 30°. To do this, you need to prepare special steel linings.

A simple device to facilitate the collection of wild mushrooms

I must say that since this hole is very close to the end of the slats, I deliberately took a drill with a diameter of not 6 mm, but half a millimeter larger, so that when inserting a furniture bolt I would not split the end of the slats.

Step 2. Assembling the device. We insert a furniture bolt into the hole of the rail and put our board with a knife blade on it, screw it with a wing nut and washer.

Thus, our device is ready!

Here's a view of it from different angles.

Although, of course, this is a temporary measure of protection, and in the future it will be necessary to make some kind of full-fledged cover that can be put on the rack with the knife in the folded position.

Device testing.

Well, now let’s test this device in real conditions, when picking mushrooms.

Just under the tree grow two suitable mushrooms from a variety of rows, the so-called “purple rows”.

Moreover, I note that we do all this without bending over at all.

But I cut two more of the same mushrooms, and they turned out to be fused.

Well, there’s nothing you can do about it, but bending down and picking mushrooms that have already been cut is still much easier and more convenient than cutting it manually every time and bending down to pick up a cut mushroom.

This is how many mushrooms I have already collected using my device.

In general, practice has shown that this device is very convenient to use. And at the same time, you really don’t have to bend down, especially when picking large mushrooms.

So I think that this device will serve me well this fall and beyond.

Well, I’ll end here, and I wish all my DIY colleagues good health and successful trips to the forest for the gifts of nature!

Chopper with a working matrix of saws

The assembly of this unit is somewhat simpler than the previous one; there is less welding work. For the shredder you will need:

wood saws with hard alloy teeth – 20 pieces;
separating washers 5 mm thick with a hole of 20 mm – 19 pcs.;
sheet steel 2 mm thick;
pipes for making a frame;
shaft with threads at the ends with a diameter of 20 mm;
2 rolling bearings;
fasteners (bolts and nuts)
pulleys, belt.

This simple garden shredder is assembled by alternating washers and saws on a common shaft, after which they are compressed from the sides with nuts. Washers are placed between the saws so that their thicker carbide cutting parts do not press against each other and are not compressed when the nuts are tightened. Then the bearings are pressed onto the shaft and installed in cages welded to a frame made of pipes.

The remaining work on assembling the chopper is carried out as in the previous version: it is necessary to make a belt drive on pulleys with the engine attached to the frame, make a casing with a hopper and put them in place, as shown in the photo:

Note. During operation, the resulting matrix of circular saws can become clogged with small fractions of wood, and sometimes wood chips get stuck in it. But carbide teeth serve for a long time without sharpening; the main thing is not to overheat them, otherwise the soldering tips may fly off.

Chip cutter for wood concrete: principle of operation

The main components of the machine are a chipping disk with knives and a rotor with hammers and blades. The disk is mounted on a working shaft, which is driven by a pulley connected by a belt to the engine. The shaft rotates in two roller bearings, and the motor is mounted on a frame.

The supply of raw materials is carried out manually, that is, everything that is to be processed is thrown one at a time into the receiving hopper, and then the wood waste itself is pulled under the working knives and hammers. At the final stage, the chips fall onto the sieve using the blades and fly out of the chip cutter through the unloading hole.

At the entrance, the receiving hopper is made in the form of a funnel in order to simplify the supply of raw materials for processing and make this process safe for hands.

The machine for making wood chips has the following characteristics:

engine power – 7.5 kW;
rotation speed on the engine working shaft – 3000 rpm;
rotation speed of the shaft on which the disk with cutting knives is fixed is 1500 rpm.

When the rotation speed of the shaft with the disk increases, a certain amount of wood raw material may be ground into dust (naturally, this is bad), although the productivity of the wood chipper increases.

We make a simple drill, practically from rubbish

A drill or engraver is a great help in “desktop” work. In fact, there are many different attachments and their sets on the market that allow you to cut various materials, clean, grind, engrave, again drill, all sorts of little things, often in very hard-to-reach places. The drill can be successfully used in jewelry, amateur radio practice, model making, small plumbing and carpentry work, and when working with glass. This is a truly universal tool that greatly contributes to the integrity of the fingers and for small work, it would be nice to always have it ready, at hand.

An example of a well-thought-out mechanism is the grinder from Chapai

The brand “from Chapay” is a universal tool due to its competent and practically thought-out device and design

Chapaev machines are capable of processing wood, metal, plastic, and stone. They are ordered by people who need constant use of this tool and its special settings. Such grinders are an example of homemade devices with high productivity. Here is a short overview of one such model:
