Straw shredders can come in handy.farm, especially if you are breeding and keeping livestock. You can make this design yourself, but you can also buy it in the store. However, the first option will undoubtedly cost much less.
Methods of making shredder
Make yourself describedequipment can be in several ways. After reading them, you can choose the most suitable for you. Drawings straw chopper will help determine the choice. So, the first production version of the shredder involves the use of a drill. The grinding process will resemble the work of a kitchen combine. Here you also need a cylindrical body, which serves as a simple bucket, which is a well-sharpened knife. If you run it in a circle at a significant speed, the straw will be cut. In order to perform such a unit, you should use a Temp dual-mode drill with a power of 850 watts. The knife must be made of a hacksaw blade. The secret lies in the sharpening of a knife. If these manipulations are carried out correctly, then the straw will not become confused in the blade.
Such straw shredders should be made by one-sided sharpening knife. It must be placed sharpened surface down.
Production of a grinder from a vacuum cleaner
If not available drill that could beuse for the manufacture of the device, you can use a vacuum cleaner brand "Typhoon". On the working principle, this device will not differ from the previous one, but it will look more attractive, in addition, the performance of the unit will be much more. If in the above 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 hole, which is located in the side of the vacuum cleaner. Chopping hay, straw with their own hands should be made so that there was an opportunity to correct the situation in which the straw will be scattered. This can be done by using a protective cover. Of course, this installation does not look as impressive as compared to the purchase, but it works perfectly and does not cost anything.
Recommendations for work
Home straw choppers canmanufactured on the same principle, but using any container. Only you need to pick one that has a cylindrical shape. It may even be an old pan or a pipe of suitable diameter. The unit can be equipped with an engine. It is necessary to use the one that has a power equal to 180 watts. This is permissible to borrow from a washing machine, which is no longer used. For the manufacture of knives, you can use the old hacksaw blade, and as racks you can prepare a rectangular profile, the dimensions of which are 15 x 15 mm.
Mounting components of the unit
Изготавливая измельчители соломы, необходимо prepare also the sleeve, which should have a height equivalent to 40 mm. On this element it is necessary to fix the knives. The sleeve can be prepared on a lathe.
Pre-powered engineremove the pulley, should be fixed to the container on the heels, placing the bottom. In order to fix the knives, it is necessary to use water nuts, whose diameter is equal to 32 mm. In the process of manufacturing sleeves in advance it is necessary to cut the thread to install the nuts. Do not forget about the hole for the motor shaft.
To provide a solid mount on the shaft,the sleeve should be done 2 holes, the diameter of which is equal to 7 mm. In them, after you have to cut threads M8, which will allow you to mount the locking bolts. On the motor shaft on the back side, the platforms must be machined to increase the bolt mounting strength. Departing from the top of the cylinder 15 mm, it is necessary to remove the edges, using the grinder for this, it will allow to form a square, the side of which should be equal to 25 mm. Knives are supposed to be put on him.
Knife making
The straw chopper has its maincomponent - knives. You can make them from a hacksaw blade, from which four blanks are cut by a grinder. In the central part of each element should be prepared by a square hole, the side of which should be equal to 26 mm. The stiffness of the original web will affect the width of the parts. Position the knives closer to the bottom. In order to well sharpen the cutting edges, it is necessary to apply sharpened. The bolts that hold the bushing should be above the blades. If it is not possible to make a hole for chopped straw, placing it under the knives, it should be done at the side. For which the Bulgarian enters, with which you can make a 7 x 7 circle.
Making a straw chopper is necessaryto form a body guide element, for this purpose steel is used. To grinder the housing must be fixed with M3 bolts. Care must be taken to ensure that the installation platform has maximum stability. For what its base is necessary to do more in comparison with the upper part. It must be made as functional as possible, and it must also be comfortable. The hay, straw chopper must have such 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, it is preferable to close the sheets of steel. In the racks you need to prepare the thread for the installation of M3 bolts, with which the blades are fixed to the platform body.
Making a grinder from a pump
Hay, straw chopper can be made fromimprovised materials. In order to perform the simplest unit, you can use the pump “Agidel”, by the way, any similar electric motor is suitable, however, you need to choose the one that will be able to produce about 3000 rev / min. In addition, it must be powered from the 220V network. An old aluminum pan will also be needed. Useful and hacksaw, designed to work on wood. It will be needed in quantities of several pieces, and will be needed for the manufacture of knives.
When you make a straw chopperwith your own hands, you need to think about how the installation will start up; for this, a button is useful, which will come from the old washing machine, and prepare the plug and the power cord.
Recommendations for manufacturing
A straw chopper with his own hands should bedesigned in such a way that the motor is located under the pan. While the start button should be located at the back of the platform, this will allow you to easily reach it.
Safety regulations
DIY straw chopper, drawingswhich are presented in the article, must be used very carefully in the process of operation, because the design is based on sharp knives, which are considered quite dangerous, as they can cause serious damage to a person.
If you made a machine that works fromelectricity, it is necessary to observe extra care, only so the grinder will serve for a long time and will not cause injuries. Especially carefully you need to ensure that the device does not try to use children, this can lead to unpleasant consequences. The straw chopper with its own hands, the drawings of which must be considered before the start of work, must be used only for its intended purpose.
