Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, namely to devices for cutting root crops. The device contains a housing and a rotor. The body consists of two parts: the lower one is fixed, with an unloading window and the upper one is folding, with a loading window. The upper part of the body has a hinged loop connection on one side, and a screw clamp on the other side. The rotor is a set of pairs of drums rotating towards each other. The drums are fixed on axles. One of the drums is driven through a safety clutch from a gear motor. Rotation from one drum to another is carried out through a gear train. U-shaped grooves are symmetrically located on the outer surface of the drums, in which knives are installed and fixed in these grooves with the help of an axis fixed from displacement on both sides of the drum by a washer and a cotter pin. Adjusting sleeves are located between the knives, with the help of which the required cutting thickness is selected.

EFFECT: use of the invention will improve productivity, reliability and cutting quality of root crops.

Description

The invention relates to agriculture, namely to devices for cutting root crops into plates on livestock farms and complexes.

A device is known (see A.S. No. 351533 of the USSR, IPC A23N 15/00) for cutting root crops, containing a hopper, a rotor with blades and a fixed knife.

The disadvantages of this device are low productivity, unreliability during operation, the quality of the finished feed does not meet the zootechnical requirements for the issuance of farm animals, as it cuts the fruit into two unequal parts.

As a prototype, a device for cutting root crops (see A.S. No. 862907 of the USSR, IPC A23N 15/00, B26D 1/44), containing a hopper, an additional rotor mounted parallel to the main one with the possibility of counter rotation, the fixed knife is made cruciform shape, and the blades of the knife have bevels directed to the axis of its symmetry with the formation together with the blades of the rotors of the orienting channel.

The disadvantages of this device are the difficulty in maintenance and repair, unreliability in operation, the quality of the finished feed does not meet the zootechnical requirements for the issuance of farm animals, as it cuts the fruit into four unequal parts.

The technical task is to increase productivity, reliability in operation and the quality of cutting root crops.

In FIG. 1 shows a device for cutting root crops, general view; in fig. 2 - the same, top view.

To solve this technical problem, a simple design of a device for cutting root crops is proposed, which consists of a body 1 and a rotor 2.

Case 1 consists of two parts: lower 2 is fixed, with an unloading window, and upper 3 is folding, with a loading window. The upper part 3 on the one hand has a swivel loop connection 4 , and on the other hand, a screw clamp 5 , which is a hinged screw with a wing nut, which allows access to the rotor 2 during its maintenance and repair.

Rotor 2 is a set of pairs of drums 6 and 7 rotating towards each other. The drums 6 and 7 are fixed respectively on the axes 8 and 9 , one of which is driven through the safety clutch 10 from the gear motor 11 . Rotation from one drum to another is carried out through a gear train 12 . U-shaped grooves are symmetrically located on the outer surface of the drum, in which knives 13 are installed and fixed in these grooves with the help of an axis 14 , fixed from displacement on both sides of the drum with a washer and a cotter pin. Adjusting sleeves 15 are located between the knives 13 , with the help of which the required cutting thickness is selected.

The device works as follows.

Pre-washed root crops 16 , for example, by a conveyor (not shown in the figure), through the loading window of the upper part 3 of the body 1 , they begin to be evenly fed into the zone between the knives 13 , captured by them and pressed through, crushed into slices of a certain thickness without loss of juice. Further, through the unloading window of the lower part 2 of the housing 1 , the crushed root crops 16 are loaded, for example, into the feed hopper (not shown in the figure). This design of the proposed device is reliable in operation, easy to maintain and repair, allows you to get slices of a certain thickness, and therefore high productivity.

Claims (1)

A device for cutting root crops, containing a housing and a rotor, characterized in that the housing consists of two parts: the lower one is fixed, with an unloading window and the upper one is hinged, with a loading window, and the upper part has a hinged loop connection on one side, and on the other - a screw clamp, which is a hinged screw with a wing nut, to provide access to the rotor during its maintenance and repair, in addition, the rotor is a set of pairs of drums rotating towards each other and fixed respectively on the axles, and one of the drums has a drive through a safety clutch from the motor-reducer, rotation from one drum to another is carried out through a gear train, and U-shaped grooves are symmetrically located on the outer surface of the drums, in which knives are installed, fixed in these grooves with the help of an axis fixed from displacement on both sides drum with a washer and cotter pin, while between the knives there are adjusting tools, with the help of which the required thickness of cutting root crops is selected.
