GRINDER OF GRASS WITH OWN HANDS (VICTOR TALANIUK)
I think no one needs to explain how much such a chopper is needed on the farm. After all, the resulting mulch from weed vegetation, vegetable haulm and mulch branches is simply indispensable in the arsenal of a supporter of organic farming. This grinder is also useful for preparing feeds for animals and poultry.
The only problem is that it is not always possible to buy a sufficiently powerful chopper, and it costs a lot. Therefore, I decided to construct it myself.
The proposed construction of the grinder for green mass and succulent fodder is a complex of assembly units located on the corner frame. We list all these details.
1. Asynchronous electric motor with a power of 0,5 ... 0,7 kW and a rotation speed of 3000 rpm
2. Starting equipment (starting capacitor, designed to start the motor selected by you and a special starting button - by analogy, as in old washing machines).
3. Grinding knife installation complete ..
4. Standard products (bolts, screws, nuts, splines, drive gear 0 950 mm length from the car VAZ, 2 bearing 60304) and their dimensions are completed in the assembly process.

In the manufacturing process of the shredder, the following technological operations are performed:
- - marking;
- - turning;
- - milling;
- - drilling;
- - thread-cutting;
- - planing (grooving);
- - locksmith;
- - welding.
Assembly and commissioning work includes:
- - setting the alignment of the belt and pulleys when fixing the welding units on the frame;
- - adjustment of belt tension;
- - adjustment of the gap (3 ... 5 mm) between the knife and the loading chute, which plays the role of a counter plate, and some others.
Next, start the assembly.
1. Three angles of 25 × 25 mm are placed on the horizontal plane of the frame, intended for fastening the legs of the electric motor.
2. The knives are mounted on the knife body with 4 bolts М6х25 with additional installation of spring washers and lock nuts MB.
3. The fitting of the 60304 bearings on the shaft and in the glass should be tight.
4. The lid of the glass and the glass are connected to the 4 with MB screws with a cylinder-conical head, which, after assembly, are turned around from possible unscrewing during vibration.
5. The assembled shaft, bearings, cup and cover are fastened through 4 holes in the rear wall with MbhZO bolts using spring washers and nuts.
6. For exact alignment of the marking of 6 d8 mm holes in the rear wall and similar ones in the front, through the drum eyes marked and welded earlier, punch and then drill these 12 d8 mm holes through which the drum is attached to the front and rear walls.
7. The arcuate discharge window with a length of 130 mm at the bottom of the drum can be cut through the entire width, i.e. 75 mm, cutting wheel after securing the drum to the rear wall. Such a wide unloading window will allow you to freely throw the crushed mass out of the drum.

DIY GRASS CHOPPER - TIPS AND IDEAS
HOW I MADE THE HERB GRINDER
Grass can be chopped for a variety of purposes, such as for poultry feed or to be used as mulch or fertilizer. A small volume can be cut with a knife, but if there is a lot of grass, then this becomes difficult.
I came up with a simple drill attachment that helps you easily grind a fairly large amount of grass in a couple of minutes.
I took an old whisk for mixing the mortar and a broken braid as a basis.
With a whisk, I cut off everything superfluous with a grinder, leaving only the rod. At the end, I cut the thread for the nut with a die.
From the scythe I cut off a piece a couple of centimeters shorter than the diameter of the container in which I planned to grind the grass. The width of this workpiece must be at least 5 cm. In the middle of the workpiece, I drilled a hole for attaching to the rod. It must be the same diameter as the diameter of the thread, not more, otherwise the knives will scroll. On the blades he made one-sided sharpening, sharpened with an ordinary grinder.
The nozzle is ready. Now we pour grass into the container, turn on the drill with a nozzle and lower it into the container. Everything grinds up nicely.
I plan to weld the second tier of knives, 10 centimeters higher than the first, so the work will speed up and it will take even less time to grind.
