Abstract

A DEVICE FOR CUTTING MATERIALS, an advantage of a naturally boneless machine containing a hopper, a feed auger placed in it, a working auger located in the housing, knives and alternating grids with them in order to increase the efficiency of the device in operation by preventing the grinding products from being expelled from the working chamber, the feed screw is installed perpendicular to the worker, and the inner surface of the part of the working screw body located above the feed screw is made ayuscheys toward the feed material and provided with ribs on the helix inclined in the direction of material supply and forming with the turns of the screw podpityvayu1tsego straight angle.

Description

The invention relates to devices for grinding materials, namely, cutting machines, mainly for grinding boneless meat and can be applied in the dairy, food and other industries.

A well-known cutter for grinding boneless meat, containing a hopper, two parallel feed spiral screws located therein, a cylindrical body with a working screw and cutting mechanism of cross-shaped multi-blade knives and alternating disk knife grids alternating with them. The working auger and the cruciate knives mounted on its shank are rotated by the electric motor 1.

However, in this cut, there is an uneven supply of the material to be ground into the cutting mechanism, which leads to a reduction in the quality of grinding. In addition, the feed spiral augers inefficiently supplied crushed material into the body of the working auger.

The closest to the technical essence of the invention is a device for grinding materials, containing a feed hopper, feed cheeks located therein, work cheeks located in the housing, knives and alternating grids 2 alternating with them.

However, the known device is characterized by insufficient efficiency in operation due to the displacement of a part of the crushed product from the working chamber of the housing back to the hopper, which reduces both the performance of the device and the quality of the finished product.

The purpose of the invention is to increase the efficiency of the device in operation by preventing the grinding products from the working chamber.

This goal is achieved by the fact that in a device for grinding materials, mainly boneless, containing a feed hopper, a feed screw placed in it, a working auger located in the housing, knives and alternating gratings, the feed screw is perpendicular to the working one, and the inside surface the body of the working screw, located above the feed screw, is tapered towards the material supply and provided with ribs along a helical line inclined towards the material supply and with the turns of the feed screw right angle.

FIG. 1 shows a device for grinding materials, a general sectional view; in fig. 2 shows section A-A in FIG. one.; in fig. 3 shows a section BB in FIG. 2

The device contains a hopper 1, a feed screw 2 placed in it, a working screw 3, a housing 4, knives 5 mounted on the shank 6 of a screw 3 alternating with blades 5 of the grille 7, moreover, to increase the efficiency of the device by preventing product displacement for grinding from the working chamber 8 of the housing 4, the feed screw 2 is installed perpendicularly crosswise to the working screw 3, and the inner surface 9 of the housing 4 of the working screw located above the feed screw 2 is made tapering towards the feed ala and provided with ribs 10 on a screw line. The ribs 10 are inclined in the direction of the feed of the crushed material and

0 form a right angle with the turns of the feed screw 2, which promotes the movement of material into the chamber 8 under the action of the turns of the screw 2.

The device works as follows.

5 The crushed material is fed to the hopper 1 so that it always contains a certain amount of this material. The rotational feed screw 2 feeds the material being crushed in the direction of arrow G (FIG. 1) into the working chamber 8 of the housing 4. The material fills the inter-turn cavity of the rotating working screw 3, which, having developed pressure on the material, pushes it through the receiving window of the brush. 11, and the rotating knives 5 push it through the openings to the grids 7. The grinding product leaves through the throat of the clamping nut 12 into the receiving container (not shown).

The degree of grinding material depends

0 from the set of knives and grids, from the size of the holes in the output grid 7.

The working auger 3 and the knives 5 planted on its shank 6 are rotated from the electric motor 13 via a V-belt transmission 14 or through a V-belt transmission and a gearbox. The choice of the type of drive depends on the power of the device and the type of material crushed on it or about a product.

Thus, the use of the invention makes it possible to increase the efficiency of the device in operation by preventing it. displacement of grinding products from the working chamber.
