Description

one

This invention relates to mend-up thinking.

A device for grinding meat is known, which has an inclined mounted auger-feeder with a hopper to a cutting mechanism fixed on the shaft with fixed rotors — receiving and output — and a knife,

Such a device is not sufficiently high reliability in operation.

The purpose of the invention is to increase the reliability of work.

This is due to the fact that the device is equipped with a horizontal chamber with a conical portion connected to the auger feeder, n "; 1 the smaller base of which is adjacent to the cutting mechanism, and the largest is located at the intersection of the geometrical axes of the feeder and the shaft of the cutting mechanism, as well as

fixed on it are nanoravluyuschie for the incoming. CA, covering the shaft of the cutting mechanism.

In addition, the jaw feeder can be equipped with a clamp for connecting

to the vacuum system, located opposite the hopper, and is installed with the possibility of rotation.

To regulate the speed of rotation of the shaft of the cutting mechanism, the device is equipped with a pressure sensor mounted on the receiving grid.

FIG. 1 shows a general view of the device with a longitudinal section; in fig. 2 knife shaft cover with direction; in fig. 3 - receiving grid.

Claims (4)

The device contains a grinding chamber 2 installed on the CTaimne 1, inside of which there is a cutting mechanism including a receiving grid 3 with an annular groove 4 and an output grid 5c with a clamping nut 6, as well as a knife 7 driven by the motor 8 through the shaft O. The receiving grid is fitted with a pressure sensor 1O. The shaft is provided with a protective housing 11, which enters at one end into the annular receiving grid of the receiving grid, while the other rests on the wall of the grinding chamber. The casing 11 has guides 12 for the posting of the feeder 13, which is installed with possible: turning around the hinge 14. The feeder contains a hopper 15 with a throat 16 and a fitting 17 connected to the vacuum line. The screw 18 is driven by the rotational drive motor 19. To seal the raw materials entering the grinding, chamber 2 has a cone-shaped section, the smallest base of which is adjacent to the cutting mechanism, and the largest is located at the intersection of the geometric axes of the feeder and the shaft of the cutting mechanism. The device works as follows. . The raw materials supplied to the grinding are fed through the loading hopper 15 and the neck 16 to the feeder 13, simultaneously with the help of the gearmotor 19 the feed jaws 18 are brought into rotation and the feeder 13 is connected to the vacuum line through the nozzle 17. The creation of a vacuum in the initial supply area of the raw material prevents the formation of raw material arches in the neck 16; A feed 18 is supplied with raw material to chamber 2, where it is guided by means of guides. 12, it is evenly applied to the receiving grid 3. Moreover, due to the presence of a cone-shaped section in front of the receiving grid, it is compacted. After the pressure of the zone in front of the receiving grid 3 reaches a value equal to the sum of the pressures of the outflow of raw materials through the grid, the pressure sensor Yu sends a signal to the actuator not shown), which includes an electric motor 8, which rotates the blade shaft 9. crushed and discharged into the receiving tank. If during operation the amount of raw material supplied by the screw exceeds the throughput of the cutting mechanism ,; depending on the area of the holes in the output grid and the speed of rotation of the blade shaft, the sensor 10 detects an increase in pressure on the receiving grid and sends a signal to the automatic control system for a proportional increase in the speed of rotation of the knife shaft 9, otherwise, i.e. if the amount of raw material supplied to the grinding is less than the throughput of the cutting mechanism, the sensor 1O detects a decrease in pressure on the receiving grid and sends a signal to the automatic control system for a proportional decrease in the speed of rotation of the blade shaft. This ensures a constant match between the throughput of the cutting mechanism and the performance of the feed screw, as well as the high quality of the crushed raw materials. For sanitization and repair, the feeder 13 is rotated around the hinge 14, providing ease of maintenance of the device. Claim 1. A device for grinding meat containing an inclined mounted auger feeder with a hopper and a cutting mechanism fixed with a shaft on a shaft with fixed slats — receiving and output knives, is different. so that, in order to increase the reliability of work, it is equipped with a horizontal chamber connected to the screw feeder with a cone-shaped section, the smallest of which is adjacent to the cutting mechanism, and the largest is located at the intersection point of the feeder and shaft of the cutting mechanism, as well as guides fixed to it for the incoming meat, which encloses the shaft of the cutting mechanism. 2. The device according to claim 1, characterized in that the screw feeder is provided with a nozzle for connection to a vacuum system located opposite the feed hopper. 3. The device according to claim 1, characterized in that the screw feeder is installed with the possibility of rotation. 4. The device according to claim 1, characterized in that, in order to regulate the speed of rotation of the shaft of the cutting mechanism, it is provided with a pressure sensor mounted on the receiving grid.
