Technical Field

The application relates to a slaughtering tool, in particular to a belt type splitting saw.

Background

Splitting saws are of vital importance to animal slaughterhouses, where the split is required for unhaired or skinned animal carcasses after opening and cleaning the chamber for ease of transport, storage, processing and sale. Because the dehaired or skinned livestock carcass is split into two halves, this operation is commonly referred to as splitting and the equipment used is referred to as a splitting saw.

Currently, most slaughterhouses use bridge type splitting saws, reciprocating type splitting saws to split the halves, and even some small-scale slaughterhouses still use knife splitting axes to chisel the halves, except that some large and medium-sized slaughterhouses use automated mechanical equipment to complete the splitting operation.

Pure manual knife splitting axe chisels, bridge type splitting saws and reciprocating type splitting saws have the defects of high labor intensity, low splitting efficiency, high bone and meat loss, poor meat quality and the like.

The band-type splitting saw is being gradually adopted because of the advantages of light equipment main body, high working efficiency, cleanness, sanitation and the like. As band splitting saws are increasingly being used by slaughter houses, some of the associated problems are also exposed. Because the slaughtering line is too old or because the slaughtering line is designed to be of insufficient height and the carcass of the pig must be hung within a limited height, the slaughterhouse has to choose a straight hook (flat hook) to reduce the distance between the hanging point and the pubic bone of the pig. This results in a small sawing space when the splitting operation is initiated, which is difficult to accomplish with conventional splitting saws.
