How to make straw choppers and hay yourself

Choppers straw can be useful in the farm, especially if you are engaged in breeding and maintenance of livestock. You can make this design yourself, but you can also buy it in the store. However, the first option, of course, will be much cheaper.

Methods of manufacturing the chopper

You can make independently described equipment in several ways. Having familiarized with them, you can choose the most suitable for you. Drawings of the straw shredder will help you to decide the choice. So, the first version of the chopper manufacture involves the use of a drill. The grinding process will resemble the work of a food processor. Here, too, need a cylindrical body, which serves as a simple bucket, which is a well-sharpened knife. If you run it in a circle with a considerable speed, then the dissection of the straw will occur. In order to perform a similar unit, you should use a dual-mode drill brand "Temp", whose power is 850 watts. The knife must be made of a hacksaw blade. The secret lies in sharpening the knife. If these manipulations are performed correctly, the straw will not become entangled in the blade.

Such straw choppers should be made by the way of one-sided sharpening of the knife. It must be placed with a ground surface down.

Manufacture of a chopper from a vacuum cleaner

If there is no drill available that could be used to make the device, then you can use a Typhoon vacuum cleaner. According to the working principle, this device will not differ from the previous one, but it will look more attractive, in addition, the capacity of the unit will be much larger. If, in the above described case, the straw is in the bucket where the cutting blade is placed, now the raw material must be fed through the upper hole, while the finished substrate will exit through the lower opening that is located in the side of the vacuum cleaner. Chopper hay, straw own hands must be made so that there is an opportunity to correct the situation in which the straw will scatter. This can be done using the protective cover. Of course, such a setup looks not so representative compared to the purchase, but it works perfectly and does not cost anything.

Recommendations for work

Straw shredders at home can be manufactured on the same principle, but using any capacity. Only pick up the one that has a cylindrical shape. It may even be an old saucepan or a piece of pipe of a suitable diameter. The unit can be supplied with an engine. Use one that has a power of 180 watts. This is acceptable to borrow from a washing machine, which is no longer used. For the manufacture of knives you can use the old hacksaw blade, and in the role of racks you can prepare a rectangular profile, the dimensions of which are 15 x 15 mm.

Fastening of component parts

Making straw choppers, it is necessary to prepare also a bushing, which should have a height equivalent to 40 mm. On this element, it is necessary to fix the knives. The bushing can be prepared on a lathe.

The engine, from which it is first necessary to remove the pulley, should be fixed to the container on the studs, located at the bottom. In order to fix the knives, it is necessary to use water nuts, whose diameter is 32 mm. In the process of manufacturing the bushings, it is necessary to cut the thread for nuts in advance. Do not forget about the hole for the motor shaft.

To ensure a strong attachment to the shaft, two holes with a diameter of 7 mm should be made in the bushing. In them, afterwards, it is necessary to cut the M8 thread, which will allow mounting the locking bolts. On the shaft of the motor from the back side, it is necessary to pierce the areas to increase the strength of the bolt attachment. Having deviated from the top of the cylinder 15 mm, it is necessary to remove the faces, using a grinder for this, this will allow to form a square, the side of which should be equal to 25 mm. It is supposed to put knives on it.

Manufacture of knives

The straw chopper has its main component - knives. They can be made from a hacksaw blade, from which four blanks are cut through the Bulgarian. In the central part of each element should be prepared on a square hole, the side of which should be equal to 26 mm. The stiffness of the original fabric will affect the width of the parts. Place the knives closer to the bottom. In order to sharpen the cutting edges, it is necessary to apply a sharpener. Bolts that hold the sleeve must be placed above the knives. If it is not possible to make a hole for the chopped straw, placing it under the knives, it should be done from the side. For what the Bulgarian enters, which can be made a circle of 7 x 7.

Making a straw shredder, it is necessary to form the guide element of the body, for this, steel is used. To the chopper, the body must be fixed with M3 bolts. Care should be taken to ensure that the installation platform has maximum stability. For what its base it is necessary to make more in comparison with the top part. It must be made as functional as possible, in addition, it should be convenient. The hay and straw shredder must have a platform that will not only hold the plant, but also protect the motor. Its fixation must be made to the container using three M6x45 bolts. But the side faces of the platform are preferable to be covered with steel sheets. In the racks, you need to prepare a thread for the installation of M3 bolts, with which the cloths and fixed on the body of the platform.

Manufacture of a chopper from a pump

The hay shredder, straw can be made from improvised materials. In order to perform the simplest unit, you can use the "Agidel" pump, by the way, any similar electric motor, but you need to choose one that will be able to produce about 3000 rpm. In addition, it should be powered from the network in 220 V. It will also need an old aluminum pan. Useful and a hacksaw, designed to work on wood. It will be needed in the number of several pieces, but it will be necessary for making knives.

When you make a straw shredder with your own hands, you need to think about how the installation will be started, this is useful for a button, which will be a PNV from an old washing machine, also prepare a plug and an electric cord.

Recommendations for manufacturing

The straw shredder must be made by hand so that the motor is placed under the pan. While the start button should be located at the rear of the platform, it will easily reach it.

Safety regulations

The straw chopper with its own hands, the drawings of which are presented in the article, should be used very carefully during operation, because the design is based on sharp knives that are considered quite dangerous, since they can inflict serious damage on a person.

If you have made a device that works on electricity, then you must be extra careful, only this way the chopper will serve for a long time and will not cause mutilation. Particular care must be taken to ensure that the device is not used by children, it can lead to unpleasant consequences. The straw chopper with your own hands, the drawings of which must be considered before starting work, must be used only for the intended purpose.
