Kruporushka own hands: drawings, photos

If you own an animal farm, you know very well how useful a grain crusher is. With this equipment, you can quickly replenish the supply of food for poultry and rabbits, to prepare a combination for cattle. To find an inexpensive grain crusher in the market of the corresponding goods is quite difficult. For this reason, the crumpet can be made by hand.

Making a grain crusher from an old vacuum cleaner

Kruporushka own hands can be made of an old vacuum cleaner, so do not get rid of the old household appliances. He can borrow a motor. Among other things, it will be necessary to use a sheet of plywood, the thickness of which is 10 millimeters. It will take a metal plate that will perform the task of the knife. The working chamber will be made of steel strip. It will be necessary to stock up with wooden pins, as well as nuts and washers. It will take a bushing, as well as a hopper and a flap, which are necessary for feeding the grain.

Features of work

Kruporushka own hands should be made by technology, which involves the preparation of the base. For this purpose, you should use a plywood sheet, from which it is cut out, and then a square is cut out, the side of which should be equal to 300 millimeters. On top of it, you should fix the working electric motor, borrowed from the vacuum cleaner. In this case, it is necessary to place its lower part in such a way that it protrudes by 40 millimeters.

Making a knife for equipment

The crusher with its own hands should be made using a knife, which should rotate at a high speed, due to which the grinding of grain will occur, this element must be carried out separately. To do this, you will need to use a steel plate, which should measure 15x200 millimeters, while the thickness should be equal to 1.5 meters. Materials are preferable to choose the strongest ones. In addition, you can use car holders or other parts that can be borrowed from household appliances. To sharpen the knife follows in the form of a blade, for this, both edges must be processed towards the axis of rotation. When making a croaker for the house with your own hands, you can experiment with the shape, giving the blade the look of a propeller or mowing corners. With the help of emery it will be possible to correct the plate horizontally and vertically. Afterwards, in the central part of the working surface of the knife, it is necessary to make holes for the diameter, suitable for the motor shaft of the vacuum cleaner. The knife must be fastened to the threaded tail using a bushing, two washers and a nut.

Making a working chamber and a bunker

When a croaker for the house is made by hand, it will be necessary to perform the chamber, for which it is necessary to apply a steel strip, its length should be 700 mm, with about 10 mm needed for fastening, while the width should be more than 60 mm. The steel workpiece must be rolled into a ring, and the rib bent to the outside along the perimeter of the chamber. The resulting flanges should not be more than 10 millimeters in width, which is required for fixing with the base and for mounting the screen.

When the croaker is hand-made, the drawings of which can be prepared independently, the crusher must be firmly fixed, for this purpose, you will need to install fonts from the bottom of the camera, which will be needed in the number of three pieces. Remove them from each other at equal distance.

Sieve making

Before you make a croaker with your own hands, you need to think about how the sieve will be. It can have any diameter of the holes. The parameters of this element will depend only on what result you want to receive. So, for making flour, you need a fine mesh, to get a large grinding cell should be more. Grain will enter the working chamber from the hopper, which is fixed to the base. It must be equipped with a small hole, as well as a flap, which is made in the form of a plate. With the help of the latter it will be possible to adjust the supply of raw materials. The crust for corn should be equipped with a container, which must be installed under the screen. It will be designed to collect finished products, you can use a bucket or a pot for this.

Manufacture of a grinder according to the type of a mill

Kruporushka (own hands), the photo of which is presented in the article, can look like a mill. To do this, it will be necessary to prepare a stator, as well as a rotor, which will work on the principle of millstones. As a stand for such equipment, a box will appear on which an electric motor of low power will be mounted. It is necessary to use a single-phase unit, you can use one that is converted from a three-phase unit.

Features of making a homemade mill

The body of the equipment is a box made of metal, the thickness of the latter should be equal to 5 millimeters. The material will need to form a body in the form of a cylinder, whose diameter is 300 millimeters. The lower part will need to be equipped with a stator, while the top of the equipment should have a lid. Inside the housing, the motor and the mill must be located, which is fixed in such a way that the bearing moves on the shaft of the device, on it, in turn, the rotor is mounted. Rotating, it will develop a speed of 3000 revolutions per minute. The hopper will need to be strengthened over the body, using screws, through which the grain will be fed.

In order to be more convenient to use the equipment, you need to install a damper that will regulate the consumption of raw materials. It will take a sleeve, which will become an anther, it must be made of canvas material. Through this element will come out products. Do not forget that there must be holes for the feed and subsequent extraction of the finished grain.

Stator manufacturing features

The stator must be made using a sheet of metal, the thickness of which is 2 millimeters, while the width is equivalent to 50 millimeters. The metal strip must be bent around the circumference and placed in a mold for pouring, covering with one end of aluminum to make a bowl. Its thickness should be equal to 4 millimeters. At the next stage, the parts are given ribbing. To do this, cut a few corners, and then weld from the inner side of the stator.
