DEVICE FOR GRINDING FEED

The utility model relates to agricultural machinery, in particular to devices for grinding root crops used in farms and personal subsidiary plots.

Known feed chopper (USSR author's certificate No. 938826), containing a vertical cylindrical chamber equipped with a loading funnel and having a discharge pipe and hole. Inside the chamber, feeding blades are fixed on the shaft, and a circular knife is eccentrically placed in the lower part of the chamber.

Known feed chopper (USSR author's certificate No. 938827) containing a vertical cylindrical chamber equipped with a loading funnel and having an unloading pipe and a hole. Inside the chamber, feeding blades mounted with a slope relative to the bottom of the chamber are fixed on the shaft; a disk knife is eccentrically placed at the bottom of the chamber. The grinder is equipped with curved plates having the shape of truncated cones, to which additional

the blades.

The disadvantage of these devices is the complexity of manufacturing, the need for electricity, cumbersome.

The purpose of developing a utility model is to simplify the design, increase reliability in operation, increase mobility, and the ability to work in the absence of electricity.

The goal is achieved by the fact that the device for grinding feed contains a hopper, a bed with a fixed axle box on it, inside of which there is a horizontal shaft connected to the feed chopper. The chopper is made in the form of a circular knife, which, depending on the required size of grinding, can be replaced with another, desired configuration.

The hopper has a cone-shaped cross-section, which allows the chopper to operate over the entire surface.

Figure 1 schematically shows a device for grinding feed; in FIG. 2 - section aa of figure 1.

- 2 The device for grinding feed contains a feed hopper 6, a frame 1, which is a welded structure on which the axle box 2 made of wood is fixed. The axle box can be made of metal using standard bearings.

Inside the axle box there is a horizontal shaft 8, on which the chopper 4 is fixed. For safety, the chopper 4 is closed by a casing 3.

The device for grinding feeds works as follows: root crops are fed into the loading hopper 6, from where they then fall on a rotary chopper disk knife 4. Depending on the required size of the grinding chopper 4 can be replaced by a different configuration. The device is manually driven by rotating the handle 5, mounted on a horizontal shaft 8, which in turn drives the chopper 4. The crushed material falls down through the discharge opening 9 into a special container. On the bed 1 are two brackets 7, with which the device for grinding feed is easy - 4 is transported manually.

Claims (5)

1. A device for grinding feed, mainly root tubers, characterized in that it is equipped with a chopper made in the form of a disk with knives fixed to it of a certain configuration, and the knives can be made on the disk itself in the form of a very large grater.  2. The device for grinding feed according to claim 1, characterized in that it works without the use of electricity.  3. The device for grinding feed according to claim 1, characterized in that the chopper can be replaced with another, desired configuration, depending on the required size of grinding feed.  4. The device for grinding feed according to claim 1, characterized in that the axle box (bearing assembly) is made of wood, as a result there is no need to lubricate the rubbing surfaces. 5. The device for grinding feed according to claim 1, characterized in that the hopper has a cone-shaped cross-section, which allows the chopper to work across the entire surface.
