Description

(5) DEVICE FOR BONE SHRINKING

one

The invention relates to bone shredders and can be used in the meat industry, for example in the manufacture of glue or gelatin.

A device for grinding bone is known, comprising a housing with a knife driven in rotation and an abutment tl.

A disadvantage of the known device is that when it is working, JQ can break the knives due to the bone being jammed at the stop.

The purpose of the invention is to increase the reliability of the device by preventing. : 1 the way the knife is jammed ..

The goal is achieved by the fact that in the device for chopping bone, including a housing with a knife and a stop, the housing is provided with an axis, and the support is fixed on the last 20 and made in the form of a lever, while the opposite end of the knife is equipped with a vibrator shock absorber.

FIG. 1 shows a bone shredder, front view; in fig. 2 - And in FIG. one.

The bone shredder includes a welded frame 1, a housing 2, a shaft 3 with a drive (not shown) and knives -C, stops 5 (the number of knives and stops is set depending on the performance of the device), made in the form of a lever mounted on axis 6 bar 7, linking the ends of the levers, and a bracket 8 between which shock absorbers 9 are installed, vibrators 10, a fence 11 that serves to prevent the bone from falling under the axis 6 fixed in the plates 12, a tray 13 for discharging fractured bone, a receiving bin k. .

The bone mincer operates as follows.

Claims (1)

The bone intended for crushing is loaded into the receiving bin 1. When moving down, the bone hits the surface of the vibrating stops 5. The vibrations are transmitted to the stops 5 from the vibrators 10 mounted on the bar 7. In the interaction of the iozh C with the bone, the latter is pressed against the vibrating stops 5 and crushed. The crushed bone falls into the funnel of tray 13 and is fed for further processing. The presence of vibrating stops allows the crushing process to be carried out with less energy, because vibration reduces the resistance of the bone to fracture. With vibration, the bone fracture resistance is reduced, and the abrasive wear of the blades is reduced accordingly, which increases the service life; structure. The presence of vibrating stops prevents the pieces of the crushed bone from falling into the space between the knives, which prevents the git from jamming and increases the reliability of the device. An invention of a bone shredder, comprising a housing with a rotatable knife and a stop, characterized in that, in order to improve the reliability of the device by: the end of the lever opposite to the knife is equipped with a vibrator and a shock absorber.
