[0037] A protective plate 11 is fixedly connected to the front side of the cutter 7, and a socket 16 that cooperates with the protective plate 11 is provided on the top of the workbench 14. When the pig head is placed on the workbench 14 and the protective plate 11 is inserted into the socket 16, the protective plate 11 blocks the front side of the cutter 7, allowing only the cutter 7 to enter the pig head without touching the operator's hand, thereby avoiding accidental injury. The safety grating 13 installed on the left and right sides of the top of the workbench 14 is a photoelectric protection device that can detect whether there is any foreign object entering the working area. Once the grating is blocked, a signal will be immediately sent to the controller 5 to stop the equipment operation to prevent accidents.

[0038] When starting the pig head splitting device, the staff needs to press the start button 6 with both hands at the same time. Only after the controller 5 receives the control signals of the two start buttons 6 can the first hydraulic cylinder 9 drive the cutter 7 to move downward to prevent the user's hands from being injured.

[0039] Furthermore, the limiting mechanism 3 includes a limiting plate 301, which is movably connected to the top of the workbench 14, a second hydraulic cylinder 302 is fixedly installed on one side of the limiting plate 301, and a fixing seat 303 is fixedly connected to one end of the second hydraulic cylinder 302, and the fixing seat 303 is fixedly installed on the left and right sides of the fixing frame 2.

[0040] Furthermore, the pushing mechanism 4 includes a fixed plate 401, which is fixedly connected to the rear side of the workbench 14, and a push plate 402 is movably connected inside the fixed plate 401. A connecting frame 403 is fixedly connected to the rear side of the fixed plate 401, and a third hydraulic cylinder 404 is fixedly connected to the connecting frame 403. The piston rod of the third hydraulic cylinder 404 is fixedly connected to the rear side of the push plate 402.

[0041] The limiting mechanism 3, through the combination of the limiting plate 301 and the second hydraulic cylinder 302, can provide assistance in positioning the pig head and limit unnecessary movement, thereby ensuring that the pig head is correctly and safely positioned in the cutting groove 15 and reducing operational errors. After the pig head is split, the pushing mechanism 4 automatically pushes the pig head out, reducing the need for manual picking and reducing the risk of contact between the operator and the cutting knife 7.

[0042] A method for using a pig head splitting device with a safety protection function comprises the following steps:

[0043] First, the operator needs to place the cleaned and properly processed pig head on the workbench 14, ensure that the pig head is correctly positioned, face down, and the specific part of the pig head is aligned with the cutting groove 15, and use the limit mechanism 3 to help accurately align the pig head to ensure the accuracy and safety of the splitting process.

[0044] When the limiting mechanism 3 is working, the second hydraulic cylinder 302 drives the limiting plate 301 to move, so as to clamp and limit the left and right ends of the pig head.

[0045] The operator stands in a safe position and presses the start button 6 on the front of the console 1. At this time, the controller 5 will receive the start signal and first perform a safety check to ensure that the safety grating 13 does not detect any obstacles and confirm that there are no hands or other objects in the operating area.

[0046] The controller 5 activates the first hydraulic cylinder 9, driving the lifting plate 10 and the cutter 7 thereon to slowly descend. During the lifting process, the spring 8 plays a role of buffering and adjusting the pressure to ensure smooth movement. At the same time, the slide bar 12 ensures the smooth movement of the lifting plate 10.

[0047] When the cutter 7 is guided by the protective plate 11 and accurately enters the cutting groove 15, and with the cooperation of the workbench 14, the pig head is precisely split. During the whole process, the protective plate 11 effectively prevents the operator's hands from contacting the cutter 7.

[0048] After the splitting action is completed, the first hydraulic cylinder 9 raises the cutter 7 back to the initial position. At this time, the pushing mechanism 4 works, and the third hydraulic cylinder 404 drives the push plate 402 to push out the split pig head part to prepare for the next operation.

[0049] After completing one cycle, the device is ready for the next round of splitting of pig heads.

[0050] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
