AI Technical Summary

Technical Problem

In the prior art, manual operation of splitting the pig carcass edge is labor-intensive and inefficient, the mechanical splitting equipment has an uneven cut surface and poor aesthetics, and the double-blade structure has an uneven cut surface.

Method used

It adopts a single-blade structure, including a crank mechanism, a double-edged splitting half-blade assembly and a guide plate. The crank mechanism is driven by a motor to achieve the reciprocating motion of the double-edged splitting half-blade. The guide plate is used to guide and prevent the pig from jumping. The balance plate maintains the dynamic balance of the knife to achieve smooth cutting of the pig carcass.

Benefits of technology

The efficiency of cutting the edge of pig carcasses and the aesthetic appearance of the cut surface are improved, the splitting deviation and bone chip residue are reduced, and the service life of the tool is extended.

Abstract

The invention relates to the technical field of livestock slaughtering, in particular to a pig carcass edge-opening single-tool structure and a single-tool edge-opening method of the pig carcass edge-opening single-tool structure. And the double-edge splitting cutter assembly is fixedly installed on one side of the front end of the crank mechanism, and the double-edge splitting cutter assembly comprises a double-edge splitting cutter and a guide plate. The double-edge splitting cutter serving as a single cutter is installed on the crank mechanism, the synchronous belt is driven by the motor to be transmitted to the crank mechanism, the crank mechanism is converted into vertical reciprocating motion to drive the double-edge splitting cutter serving as the single cutter to do vertical cutting motion, and then the two guide plates are installed on the two side faces of the double-edge splitting cutter and used for guiding. When the machine head is split into halves, the guide plate moves downwards at the same time and is pressed into the split live pig trough to play a role in preventing live pigs from jumping, so that due to the fact that the double-edge splitting cutter serving as a single cutter is provided with edges on the two sides, the cutter edge is better in abrasion resistance and longer in service life, and the split live pigs are smoother and more attractive in appearance.
