Abstract

FIELD: food industry.

SUBSTANCE: invention relates to processing industry and can be used for cutting and milling horns of domestic reindeer of evenki kind. Device has loading bunker, shaft with cutting rotatory saws fixed on it, milling auger and two drives. Rotatory saws are dismountable and have different diametre. Rotary saws of different diametres are going from bigger diametre to the smaller one and from the smaller one to the bigger one making a curved line following horns shape. Adjusting washers sharpened on sides and made as ovals are situated between cutting rotary saws. There is a milling auger beneath rotary saws. Auger is made as cutting knives on one side and milling knives on the other side. Milling knives width is increasing from milling auger centre to unloading tray. Milling auger inside diametre is made as a cone with reduction of diametre from the beginning of cutting knives to the beginning of unloading tray. Distance between cutting rotary saws is set with help of adjusting washers.

EFFECT: usage of invention allows to increase quality of deer's horns milling.

Description

The invention relates to the processing industry, in particular for cutting and grinding horns of domestic reindeer of Evenki breed.

A device for grinding bone (ed. St. USSR No. 13588841, IPC A22C 17/06, 1987), comprising a vertical body, a loading hopper, an unloading pipe, a rotor, knives, a knife-grate, is known.

A disadvantage of the known device is low productivity and heterogeneous degree of grinding.

Known machine for cutting glue, etc. meat waste (ed. St. USSR No. 66945, IPC A22C 17/06 / B26D 1/22, 1946), comprising a storage hopper, a feed drum, a shaft with circular saws, an engine, a system of longitudinal grooves intersecting the annular grooves for entering the saws, water tube and discharge tray (prototype).

The disadvantage of this machine is the low degree and heterogeneity of grinding, low productivity.

The technical result - improving the quality of grinding by obtaining high-quality powder from the horns of domestic deer Evenki breed and increasing productivity.

The specified technical result, in contrast to the prototype, is achieved by the fact that the machine contains a loading hopper, a shaft with cutting circular saws fixed to it, a grinding auger and two drives, while removable cutting circular saws of different diameters mounted on a rotating shaft are made in sequence from a larger diameter to smaller and from smaller to larger, forming a curved line that repeats the shape of the horns, circular saws are separated by shims, pointed at the edges and made in the form of an oval, below is installed chopping auger, which is made in the form of cutting knives on one side and chopping knives on the other hand, and the width of the chopping knives increases in width from the center of the chopping screw to the discharge chute, and the inner diameter of the shell of the chopping screw is made in the form of a cone with a decrease in diameter from the start boundary installation of cutting knives to the border of the beginning of the discharge tray.

The distance between the cutting circular saws is regulated by adjusting washers.

Figure 1 shows a device for cutting and grinding horns of domestic reindeer of Evenki breed, general view; figure 2 shows the adjusting washer, a General view; figure 3 - adjusting washer, side view; figure 4 presents the grinding auger.

The machine consists of a frame 1 (Fig. 1), mounted on a bed 2, a loading hopper 3, mounted on a frame 1, a rotating shaft 4 mounted on bearings 5. On the rotating shaft 4, removable cutting circular saws 6 of different diameters are installed in a sequence of larger diameter to smaller and from smaller to larger, forming a curved line of cutting that repeats the shape of the horns.

Circular saws 6 are divided by adjusting washers 7, pointed at the edges 23 (Fig. 3) and made in the form of an oval (Fig. 2), with the help of circular washers 7, the distance between the circular cutting saws 6. The rotating shaft 4 is driven by an electric motor 8 through clutch 9, gearbox 10 and belt drive 11.

Guides 12 are mounted on the frame 1 under the rotating shaft 4 with circular saws 6, the cone body 13 of the grinding screw 14 is located even lower. The grinding screw 14 is installed in the housing 13, the inner diameter of which is made in the form of a cone with a decrease in diameter from the boundary of the installation of cutting knives to boundaries of the beginning of the discharge tray 22.

The grinding auger 14 is mounted on bearings 17 and is driven by an electric motor 18 through a coupling 19, a gearbox 20 and a belt drive 21. The grinding auger 14 is made in the form of cutting knives 15 on the one hand and grinding knives 16 on the other hand, and the width of the grinding knives 16 increases in width from the center of the grinding auger 14 to the discharge chute 22, which allows the cut parts of the horns and chips coming to the auger 14 to be chopped by cutting with the knives 15 and 16 of the auger 14 in stages from large to smaller by reducing the distance m Between the edge of the grinding screw 14 and the conical body 13.

A device for cutting and grinding horns of domestic reindeer Evenki breed works as follows.

The horns of domestic reindeer of the Evenki breed from the loading hopper 3 mounted on the frame are fed to circular saws 6 mounted on a rotating shaft 4, where they are sawn into equal shares.

The cut equal shares of the horns fall on the guides 12 and further on the cutting knives 15 of the screw 14. The resulting chips when cutting the horns fall on the adjusting washers 7 and are also dumped onto the cutting knives 15 of the screw 14 due to centrifugal forces.

During the rotation of the screw 14, the cutting knives 15 cut the sawn off pieces of the horns and the chips into small particles, while due to the rotation of the screw 14, small particles enter the grinding knives 16.

The completed conical design of the body 13 of the grinding screw 14 and the grinding knives 16 increasing in width allow grinding the incoming shredded chips to a finely dispersed state in the form of powder, which is then discharged through the unloading tray 22 into a receiving container, which results in a technical result - improving the quality of grinding and obtaining a uniform high-quality powder from horns of domestic deer of Evenki breed.

The increase in productivity is achieved by increasing the length of the dialed cutting saw blades corresponding to the length of the antlers of the deer, cutting into particles with predetermined thickness parameters and grinding to a finely divided fraction, which eliminates additional technological operations.

A machine for cutting and grinding horns of domestic deer of Evenki breed can be easily implemented and find application in the processing industry.
