Description

Technical Field

[0001] This utility model relates to the field of slaughtering tools, and in particular to hydraulic pig head clamps. Background Technology

[0002] In the process of removing pig heads during pig slaughter, manual methods were previously the main method. The manual cutting and removal of pig heads was a very cumbersome operation. The operator had to hold the pig's ear with one hand and use a knife in the other hand to first insert the tip of the knife into the base of the ear on the pig's neck and cut through the fat around the neck. Then, the head was pried open from the joint to separate it from the pig's body. The new method uses hydraulic drive. Taking a handheld hydraulically driven pig head shearing pliers as an example, it includes a left plier and a right plier. Both the left and right pliers include a shearing part and a driving part. The front end of the shearing part has an inwardly curved hook. A hydraulic cylinder is also fixed on the frame. The two driving parts are connected to the piston rod of the hydraulic cylinder through connecting rods. The extension and retraction of the piston rod drives the two connecting rods to open and close the two shearing parts.

[0003] Secondly, the frame is equipped with a front handle and a rear handle, both of which have control switches. When the control switches on the front and rear handles are pressed simultaneously, the piston rod of the hydraulic cylinder extends forward and the two shearing parts approach each other, thereby shearing the pig's head. However, the current hydraulic pig head clamps do not have this hydraulic drive effect during use, which makes it impossible to control the operation with pneumatic switches. This reduces the working efficiency of the pig slaughtering production line and also reduces safety, failing to meet the requirements of the food hygiene industry. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides hydraulic pig head clamps, which aim to improve the existing hydraulic pig head clamps that do not have hydraulic drive effect during use, resulting in the inability to control operation by pneumatic switch, thereby reducing the working efficiency of the pig slaughtering production line and reducing safety.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hydraulic pigsnake pliers, comprising a rear handle pneumatic block, a cylinder connecting ring rotatably connected to the bottom of the rear handle pneumatic block, a hydraulic cylinder fixedly connected to the inner side of the cylinder connecting ring, a main body air connector fixedly connected to the left end of the hydraulic cylinder, a cylinder connecting block fixedly connected to the left side of the main body air connector, a blade connecting rod rotatably connected to the rear side of the outer wall of the cylinder connecting block, a small rotating shaft rotatably connected to the front side of the outer wall of the cylinder connecting block, shearing blades rotatably connected to the outer walls of both the blade connecting rod and the small rotating shaft, a positioning support body fixedly connected to the outer wall of the cylinder connecting block near the edge, and a large rotating shaft rotatably connected to the left side of the outer wall of the positioning support body.

[0006] As a further description of the above technical solution:

[0007] The left middle of each of the rear handlebar gas blocks is connected to a right-angle air connector, the other end of which is connected to a front and rear gas block connecting air hose, and the other end of the front and rear gas block connecting air hose is connected to the front handlebar gas block.

[0008] As a further description of the above technical solution:

[0009] A front handle switch is fixedly connected to the front center of the front handle gas block.

[0010] As a further description of the above technical solution:

[0011] A rear handle switch is fixedly connected to the top right side of the rear handle gas block.

[0012] As a further description of the above technical solution:

[0013] The outer wall of the large rotating shaft is rotatably connected to the adjacent shearing blade.

[0014] As a further description of the above technical solution:

[0015] An L-shaped fixing plate is fixedly connected to the rear side of the front handle gas block.

[0016] As a further description of the above technical solution:

[0017] A lifting ring is fixedly connected to the middle of the rear side of the L-shaped fixing plate.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, when the equipment is powered on and the hydraulic system is running, compressed air is connected to the air inlet of the pneumatic switch. With both hands pressing the front handle switch simultaneously, the rear handle switch and the hydraulic cylinder piston move forward. Then, the blade connecting rod connected to the cylinder connecting block transmits power to the shearing blade, which rotates around the small rotating shaft. At this time, there are two shearing blades, which are fixed in the middle of the positioning support body by the large rotating shaft and rotate around the large rotating shaft to close the two shearing blades and achieve the shearing effect. This makes it easier for operators to use and improves convenience. Attached Figure Description

[0029] Specifically, the hydraulic cylinders 1 are tightly connected together to ensure that the hydraulic cylinders 1 can be stably positioned. The left end of the hydraulic cylinder 1 is further extended and fixedly connected to the main air connector 15. The main air connector 15 serves as the hub connecting the hydraulic cylinder 1 and is also fixedly connected to the cylinder connecting block 2 on the left side, so that the cylinder connecting block 2 can work in coordination with the hydraulic cylinder 1. The outer walls of the blade connecting rod 3 and the small rotating shaft 16 are rotatably connected to the shearing blades 4, so that the shearing blades 4 can perform complex movements under the drive of the blade connecting rod 3 and the small rotating shaft 16. Near the edge of the outer wall of the cylinder connecting block 2, a positioning support body 5 is fixedly connected. The positioning support body 5 supports the frame and provides additional stability and support force. The left side of the outer wall of the positioning support body 5 is rotatably connected to the large rotating shaft 6 to further realize the movement mode and function.

[0030] Please see the appendix Figure 3 - Appendix Figure 5 A front handle switch 10 is fixedly connected to the front center of the front handle gas block 7. A right-angle air connector 14 is connected to the left center of the rear handle gas block 13. The other end of the right-angle air connector 14 is connected to the front and rear gas block connecting air hose 17.
