Description

Technical Field

[0001] The invention relates to the technical field of live pig splitting machines, in particular to a crank mechanism, a live pig splitting machine head and a live pig splitting machine. Background Art

[0002] The slaughtering and processing procedures of live pigs include: showering, stabbing and bleeding, scalding and scraping, gutting, head and hoof cutting, splitting in half and secondary showering, among which the splitting in half process is completed by a live pig splitting machine.

[0003] The common pig splitting machines on the market have an external crank mechanism (which is also the knife rod) when splitting the pig in half. This makes the crank mechanism prone to breakage and the pig is prone to splitting when splitting, making the surface of the split meat very unsightly. Summary of the invention

[0006] Furthermore, the penetration parts of the two cranks and the shaft rod are staggered.

[0007] A pig splitting machine head, comprising: A crank mechanism as described above; A fixed frame, wherein the crank mechanism is located in the fixed frame, and the shaft and the rotating shaft of the crank mechanism are both rotatably connected to the fixed frame; An articulated arm, the articulated arm being fixed to the upper left portion of the fixing frame; A wheel holding assembly, the wheel holding assembly is rotatably connected to the left portion of the articulated arm; Auxiliary holding wheel, the auxiliary holding wheel is rotatably connected to the lower left part of the fixing frame; A servo motor, wherein the servo motor is fixedly mounted at the rear of the fixing frame; A synchronization mechanism, wherein the synchronization mechanism is mounted on the front of the fixing frame, and the front of the output shaft and the front of the shaft rod of the servo motor are connected to the synchronization mechanism; A splitting half knife, wherein the splitting half knife has a pair and is fixed on the left part of the crank of the crank mechanism in a one-to-one correspondence.

[0008] Furthermore, shaft seats are fixed on both the front and rear sides of the lower right end of the fixing frame, and the rotating shaft is rotatably connected between the shaft seats.

[0009] Furthermore, the wheel holding assembly includes a wheel holding frame, a main wheel holding and a cylinder. The wheel holding frame is rotatably connected to the left outer portion of the articulated arm, the cylinder is rotatably connected to the left inner portion of the articulated arm, the end of the piston rod of the cylinder is fixed to the inner wall of the wheel holding frame, and the main wheel holding is rotatably connected to the lower part of the wheel holding frame.

[0010] Furthermore, the synchronization mechanism includes a driven synchronous wheel, an active synchronous wheel and a synchronous belt, the active synchronous wheel is fixed to the front of the output shaft of the servo motor, the driven synchronous wheel is fixed to the front of the shaft, and the synchronous belt is connected between the driven synchronous wheel and the active synchronous wheel.

[0013] The beneficial effects of the present invention are as follows: by arranging the crank mechanism on the inner side of the fixed frame, the servo motor can be used to drive the synchronization mechanism, and the synchronization mechanism can be used to drive the shaft of the crank mechanism to rotate, so that the shaft can drive the two cranks to move. Because the penetration part of the shaft is eccentrically arranged with the crank, and the two cranks are staggered with the penetration part of the shaft, the two cranks can move alternately, so that the half-splitting knife can alternately split half of the pig, which not only prevents the crank from breaking, but also makes the surface of the chopped meat more beautiful.
