DE10252930A1 - Hydraulic-powered slaughterhouse cutting tool separates the root of a pig's tail from the cadaver rear end with semi-open hoop and cutting blade - Google Patents

Abstract

A hydraulic-powered slaughterhouse tool removes the tail from a pig cadaver by cutting through the base of the tailbone. The tool esp. has a U-shaped hoop (13) one end (13') of which is attached to a hand-grip (20). The other end (12) of the hoop has a curved tip (15) located opposite a cutting blade (11) which is operated by a trigger in the handle (20). The hoop forms a semi-enclosure around the tail. The sides (12, 13) describe an angle alpha of 40-70. The tip (15) forms an angle beta with the arm (12) of 120-150. The blade cutting edge is set at an angle of 15-40 with respect to the blade main axis. The hoop has a handle (40).

Description

The invention relates to a device for the fine cutting of pigs.

When cutting pigs finely, it is necessary, among other things, to remove the tail bone from the ham bone, and with it the tail. This process has since been carried out manually with a knife. Up to now there are no suitable devices for this. The position of the tail bone on the ham bone is in 1 shown. The ham 1 contains the ham bone 2 and the tail bone 3 , The tail bone 3 should be separated.

The object of the invention is a therefor suitable as possible simple, functional and to create safe device.

This task comes with the characteristics of claim 1 solved. The invention further relates to various advantageous developments, resulting from the subclaims and the graphic representation result.

An embodiment is shown below Reference to the attached Drawings closer described. They represent:

1 the ham with the ham bone and tail bone of a pig;

2 an embodiment;

3 is a schematic representation of the way in which the device according to the invention engages in the meat product.

The embodiment according to 2 includes a fixed bracket 10 with a holding edge 15 and a movable cutting blade 11 ,

The bracket is essentially U-shaped. His (in 2 ) Thighs 12 and 13 However, they do not run exactly parallel, but somewhat apart, for example at an angle α of 40 ° to 70 °, preferably 45 °. The free leg 12 points at its free end 14 the opposite of the course of the leg 12 approximately with an angle of β = 120 ° to 140 ° inward angled retaining edge 15 on that by means of a rounded transition surface 15 ' in the inner surface 15 " of the thigh 12 passes and there is a pocket-like depression 16 forms.

The linearly movable cutting blade 11 (see arrow) sits near the end 13 ' of the thigh 13 of the bracket 10 , It is through a hydraulic drive unit 20 linearly drivable, the housing of which simultaneously forms the handle on which the device is gripped by an operator during handling. The drive unit 20 shows the hydraulic connections 22 and 23 on. Such hydraulic drive units are known to the person skilled in the art, so that a detailed description can be dispensed with here.

The cutting blade 11 is formed by two surfaces, namely the side surface 11 ' and the side surface 11 '' , The side surface 11 ' runs parallel to the direction of movement of the cutting blade marked with an arrow 11 , the other cutting surface 11 '' has an angle of γ of 20 ° to 45 ° with this direction. The blade 11 is thus designed and arranged such that it cuts into the meat when moving in the direction of the arrow and separates the two parts from one another.

The distance 1 between the retaining edge 15 and the tip of the cutting blade 11 in the non-extended state shown is 5 to 8 cm, the clear height h of the through the bracket 10 formed cavity about 5 to 7 cm.

How out 3 this separating device can be seen attached to the meat product in such a way that the bracket 10 with the holding edge 15 the tail bone 3 grips from one side, so that when actuated by means of the actuating lever 30 and thus triggering the drive unit 20 , the tail bone 3 and with it also the tail is cleanly separated from the rest of the meat product.

For better handling is on the bracket 15 a handle 40 arranged so that you can work with both hands. That increases security.
