Description

The utility model relates to agriculture, namely to devices for grinding root crops in the preparation of animal feed.

A device for grinding root crops is known, selected as an analogue [1], including a hopper with countercuts, an electric motor, on the shaft of which two horizontal disks are fixed, upper and lower, horizontal knives are installed on the upper disk, on the lower disk there is a deck and blades for unloading the crushed material . The device, when installing the deck, allows you to grind root crops into pulp, and when the deck is removed, into shavings.

The disadvantage of the device is the high energy intensity of the grinding process, since the upper disk is normal cutting, which is more energy-intensive than sliding. The electric motor installed under the working chamber can get juice released during the grinding of root crops, which can lead to its failure.

Also known is a device for grinding root crops [2], including a housing, a vertical chamber, two horizontal disks, knives mounted on the upper disk, and a counter-cutter, the working surface of which is installed at an acute angle to the disk plane during its rotation. In the vertical chamber, opposite to each other at different heights, catchers are installed, made in the form of visors inclined inside the chamber, and the counter-cut is made in the form of a pocket formed by its working surface and the surface of the bar intersecting with it, installed at an acute angle to the plane of the disk, the base of which is perpendicular to the base of the working surface of the countercut [2].

The main disadvantage of this device is the inability to obtain slices of root crops. Also, the electric motor installed under the working chamber can get the juice released during the grinding of root crops, which can lead to its failure.

The prototype is a device for grinding root crops [3] which consists of a frame, a housing, a hub, an electric motor with V-belt transmission, an unloading pipe, corrugated counter knives, on which truncated segments are fixed. Windows with cutting knives are located radially on the lower part of the body. Under the action of the anti-cutting knife installed at an inclination in the direction of rotation, the material is pressed against the lower part of the body and crushed by cutting knives. The truncated segments help to reduce the frictional resistance of the crushed material against the walls of the working chamber, and the corrugated knives help to cut the material more accurately and obtain crushed root crops in the form of narrow and oblong chips.

The disadvantages of the prototype are the uneven supply of root crops to the working area, which leads to the production of crushed material of various sizes, as well as a long stay of the crushed material in the grinding zone, thereby reducing productivity.

The objective of the utility model is to increase the productivity of the plant by dosed and uniform supply of root and tuber crops to the working area of the grinder.

The technical result is achieved by the fact that in the proposed device for grinding root crops, containing a frame, a body, on the lower part of which windows with cutting knives are located radially, hubs, an electric motor with V-belt transmission, an unloading pipe, corrugated counter knives, on which truncated segments are fixed, according to utility model in the upper part of the device there is a feeding hopper, inside which there are guides made in the form of peaks, and slide gates.

The chopper of root crops is explained by the diagrams:

fig. 1 is a diagram of a longitudinal section of a root crop chopper;

fig. 2 is a diagram of a cross section of a root crop chopper;

fig. 3 is a top view of a root crop chopper.

The chopper of root crops includes a frame 1, a body 2, on the lower part of which there are windows 3 with cutting knives 4, hubs 5, an electric motor 6 with a V-belt transmission, an unloading pipe 7 with impellers 8, corrugated counter knives 9, on which truncated segments 10 are fixed, in the upper part of the device, a feeding hopper 11 is installed, inside of which there are guides 12, made in the form of peaks, and slide gates 13 for a uniform dosed supply of root crops into the working chamber 14.

Chopper root crops works as follows.

Root crops are fed into the hopper 11, then evenly enter the working chamber 13 due to the inclination of the guides 12 in the form of visors and slide gates 13. which is removed by impellers 8 through the unloading pipe 7. Under the action of the counter blades 9, the material acquires a rotational movement, and due to their inclination in the direction of rotation, it helps to press the material against the disk and, accordingly, against the cutting blades 4.

The use of the proposed utility model makes it possible to dose and evenly feed root crops into the working area of the grinder, which will ensure high quality grinding with minimal juice release and increase the productivity of the root crop grinder.
