An opening and closing component that guides the movement of pigs by opening and closing is installed at the long end of the top of the bottom plate 100. The opening and closing component includes a first lifting guardrail 110 and a second lifting guardrail 111 installed at both ends of the barrier 101 at the long end of the bottom plate 100. The area enclosed by the first lifting guardrail 110 and the second lifting guardrail 111 and the barrier 101 on the two long ends is used for temporarily storing pigs. The opening and closing component also includes a third lifting guardrail 112 installed on one side of the top corner of the bottom plate 100. The area enclosed by the second lifting guardrail 111 and the third lifting guardrail 112 and the blocking fences 101 on the two short ends is used for conveying pigs. Specifically, support columns are installed at both ends of the first lifting guardrail 110, the second lifting guardrail 111, and the third lifting guardrail 112. A railing for blocking pigs is connected in a vertical sliding direction between the two support columns. The railing is driven by electricity to rise and fall on the support columns. When the pigs need to be processed, the first lifting guardrail 110 is first opened to drive the pigs into the position between the two blocking fences 101 on one side of the first lifting guardrail 110, and then the second lifting guardrail 111 is opened to drive some pigs into the position between the second lifting guardrail 111 and the third lifting guardrail 112 on the top of the bottom plate 100; See Figure 3 A slaughter box 200 for processing pigs is installed on the short end of the bottom plate 100, and a driving component for driving pigs is installed on the slaughter box 200. The pigs located between the second lifting guardrail 111 and the third lifting guardrail 112 are driven away by the driving component. A feed port 220 and a discharge port 221 for pigs to enter and move out are respectively opened at both ends of the slaughter box 200. A mounting frame is fixedly connected to the feed port 220 on one side of the slaughter box 200, and a box door 210 for closing the feed port 220 is slidably connected to the inner wall of the mounting frame. The second telescopic rod 211 is driven by electricity, and the first conveyor belt 230 and the second conveyor belt 231 for transportation are installed at the feed port 220 and the discharge port 221. When the pig is driven to one side of the slaughter box 200, the second telescopic rod 211 is raised by the power drive, and then the box door 210 is moved out of the feed port 220. The pig can enter the slaughter box 200 through the feed port 220 and is transported and processed along the first conveyor belt 230. The processed pig is then transported to the discharge port 221 by the second conveyor belt 231 for unloading.

A fourth telescopic rod driven by electricity is installed on the electric shock rod 240. The electric shock rod 240 is connected to the main circuit through a line. The pig is transported to the bearing assembly through the first conveyor belt 230, and then the pig is shocked by electricity. The fourth telescopic rod is driven to move the electric shock rod 240 downward to the pig's head, and then the electric shock rod 240 is discharged to perform electric shock slaughter on the pig. An adjustment component for adjusting the output voltage of the electric shock rod 240 is installed in the middle position of the bottom of the slaughter box 200, and a conveying component for gas delivery is installed between the control component and the adjustment component. The pig is supported by the bearing component and the control component is driven to generate a change in air pressure, and then the change in air pressure is conveyed by the conveying component to the adjustment component, and then the voltage of the electric shock rod 240 is controlled by the adjustment component.

[0026] See Figure 7 The regulating assembly includes a fixing ring 610, a conductive plate 620, a positive electrode 621 and a negative electrode 622. The regulating box 600 is fixedly connected to the middle position of the bottom of the slaughter box 200. The fixing ring 610 is fixedly connected to the middle position of the inner wall of the bottom of the regulating box 600. A sliding hole is provided at the axis position of the inner wall of the fixing ring 610. The conductive plate 620 is slidably connected to the two ends of the inner wall of the sliding hole on the fixing ring 610. The positive electrode 621 and the negative electrode 622 are fixedly connected to the two ends of the conductive plate 620 respectively. The positive electrode 621 and the negative electrode 622 are connected to the conductive plate 620 through the conductive plate 610. 20 and the fixing ring 610 form a passage, and the positive electrode 621 and the negative electrode 622 are connected in parallel with the electric shock rod 240 in the main circuit through the line. When the conductive plate 620 slides in the fixing ring 610, the distance between the positive electrode 621 and the negative electrode 622 can be adjusted to reduce the resistance thereon. The current between the positive electrode 621 and the negative electrode 622 is the same as the current on the electric shock rod 240, which can reduce the voltage distributed by the main circuit to the positive electrode 621 and the negative electrode 622, thereby increasing the voltage at the electric shock rod 240 and increasing the intensity of the electric shock to the pig.

[0027] The adjustment assembly also includes a fixed rod 630 and an extension rod 632. An annular air cavity 611 is opened in the fixed ring 610. The fixed rods 630 are arranged in a circle and fixedly connected to both ends of the fixed ring 610 and are connected to the air cavity 611. The extension rods 632 at both ends are respectively fixedly connected to the outer walls of the positive electrode 621 and the negative electrode 622. One end of the extension rod 632 is fixedly connected to the fourth piston plate 631, and the fourth piston plate 631 is slidably connected to the inner wall of the fixed rod 630. The outer walls of the fixed rod 630 and the extension rod 632 are sleeved with a There are three springs 633, one end of the third spring 633 is fixedly connected to the outer wall of the fixing ring 610, and the other end of the third spring 633 is fixedly connected to the outer walls of the positive electrode 621 and the negative electrode 622. When the air pressure in the air cavity 611 increases, the gas can be transported to the fixing rod 630 to squeeze the fourth piston plate 631. When the fourth piston plate 631 is squeezed, it can slide in the fixing rod 630 and drive the positive electrode 621 and the negative electrode 622 to move through the extension rod 632, so as to adjust the distance between the positive electrode 621 and the negative electrode 622.

[0028] See Figure 5 The carrying assembly includes a carrying box 400 and a carrying plate 410. The carrying box 400 is fixedly connected to the middle position of the inner wall of the slaughter box 200. A fixed plate 420 is fixedly connected to the middle position of the inner wall of the carrying box 400. A first spring 412 is fixedly connected to the opposite wall of the fixed plate 420 and the carrying plate 410. When the pig is transported to the top through the first conveyor belt 230, it can fall into the top position of the carrying plate 410. At this time, the weight of the pig can squeeze the first spring 412 through the carrying plate 410, and the first spring 412 can be squeezed and contracted to drive the carrying plate 410 to move downward.

[0029] The control component includes a first connecting rod 411 and a first piston plate 413. The first piston plate 413 is slidably connected to the inner wall of the carrying box 400 and is located at the bottom of the fixed plate 420. The two ends of the first connecting rod 411 are respectively fixedly connected to the opposite walls of the first piston plate 413 and the carrying plate 410. The first spring 412 is mounted on the outer wall of the first connecting rod 411. When the carrying plate 410 moves downward, the first piston plate 413 is driven to slide in the carrying box 400 by the first connecting rod 411, so that the gas at the bottom of the first piston plate 413 of the carrying box 400 can be squeezed.

[0030] See Figure 6The conveying component includes a first air pipe 500 and a second air pipe 501, the first air pipe 500 is connected to the second air pipe 501, the first air pipe 500 and the second air pipe 501 are respectively connected to the carrying box 400 and the air cavity 611, the inner wall of the first air pipe 500 is slidably connected to the second piston plate 513, and the inner wall of the second air pipe 501 is slidably connected to the third piston plate 521. When the first piston plate 413 slides, the second piston plate 513 can be driven to slide downward by squeezing the gas. The downward movement of the second piston plate 513 can squeeze the third piston plate 521. The third piston plate 521 can be squeezed to squeeze the gas at the bottom to the inner wall of the air cavity 611.

[0031] The first air pipe 500 is slidably connected to a sliding frame 510 on the inner wall thereof. Both ends of the sliding frame 510 are provided with exhaust grooves for gas to pass through, and both ends of the sliding frame 510 are fixedly connected to a plurality of guide rods 511 arranged in a circle. The outer wall of the second piston plate 513 is provided with a plurality of sliding holes arranged in a circle. The guide rod 511 is slidably connected to the inner wall of the sliding hole on the second piston plate 513. Both ends of the second piston plate 513 and the sliding frame 510 are fixedly connected to a plurality of second springs 512 arranged in a circle. The second spring 512 is sleeved on the outer wall of the guide rod 511. A plurality of exhaust holes 502 arranged in a circle are provided at the bottom of the inner wall of the first air pipe 500. A second connecting rod 520 is fixedly connected to the wall opposite to the third piston plate 521 of the sliding frame 510. When gas enters the first air pipe 500, it can pass through the exhaust groove on the sliding frame 510 to squeeze the second piston plate 513, drive the second piston plate 513 to move down and slide on the guide rod 511. When the second piston plate 513 When the pig is electrocuted, the pig panics and drives the first piston plate 413 to move. The second piston plate 513 can slide on the guide rod 511 to adapt to the change in the position of the first piston plate 413. The sliding frame 510 will not be displaced, and the third piston plate 521 will remain stationary, avoiding the displacement of the third piston plate 521 when the pig is frightened, which will cause the distance between the positive electrode 621 and the negative electrode 622 to be adjusted, thereby affecting the stability of the voltage when the electric shock rod 240 is electrocuted.

[0032] See Figure 1The driving assembly includes a driving plate 120, which is slidably connected to the top of the bottom plate 100 and is located between the second lifting guardrail 111 and the third lifting guardrail 112. A connecting plate 122 is installed on the outer wall of the driving plate 120. The slaughter box 200 is close to the bottom plate 100. Both ends are equipped with a first telescopic rod 121 driven by electricity. The other end of the first telescopic rod 121 is installed on the outer wall of the connecting plate 122. The contraction of the first telescopic rod 121 driven by the motor drives the connecting plate 122 and the driving plate 120 to slide on the top of the bottom plate 100, and then the pigs located between the second lifting guardrail 111 and the third lifting guardrail 112 are driven.

[0033] See Figure 4 The inner wall of the slaughter box 200 is located on the top of the first conveyor belt 230 and the second conveyor belt 231, and is rotatably connected to the first rotating plate 300 and the second rotating plate 310 respectively. The first rotating plate 300 and the second rotating plate 310 are fixedly connected with a rotating rod 301 that is driven by electricity to rotate. The rotating rod 301 is rotatably connected to the inner wall of the slaughter box 200. The first rotating plate 300 is fixedly connected to the side of the carrying box 400 with multiple linearly arranged telescopic frames 303. The other end of the telescopic frame 303 is fixedly connected to a push plate 304 for pushing. The wall opposite to the first rotating plate 300 and the push plate 304 is fixedly connected to a rotating rod 301 that is driven by electricity to rotate. The third telescopic rod 302 is driven by electricity. Specifically, when the pig is transported to the top through the first conveyor belt 230, the rotating rod 301 drives the first rotating plate 300 to rotate and expand, and the pig can be transported to the supporting plate 410. Then, the rotating rod 301 drives the first rotating plate 300 to rotate in the opposite direction, and the third telescopic rod 302 drives the push plate 304 to move and push the pig to the top position of the supporting plate 410. After the electric shock is completed, the rotating rod 301 drives the second rotating plate 310 to rotate and expand, and the third telescopic rod 302 drives the push plate 304 to push the pig to the second conveyor belt 231 for transportation.

[0034] The working principle of the present invention is as follows: when slaughtering is required, the first lifting guardrail 110 is opened, and the pigs are driven into the barrier 101 at the long end of the bottom plate 100, and then the second lifting guardrail 111 is opened, and the pigs are driven into the space between the second lifting guardrail 111 and the third lifting guardrail 112. Then, the first telescopic rod 121 is extended to drive the connecting plate 122 and the driving plate 120 to move on the bottom plate 100, and the second telescopic rod 211 is used to drive the box door 210 to open, so that the driving plate 120 can be moved to drive the pigs through the feed port 220 and enter the inner wall of the slaughter box 200. At this time, the pig is transported to the top position by the first conveyor belt 230, and the first rotating plate 300 is rotated and expanded to transport the pig to the top of the carrying plate 410. The first rotating plate 300 rotates in the opposite direction and the third telescopic rod 302 drives the push plate 304 to move to completely push the pig to the top of the carrying plate 410, and is slaughtered by electric shock of the electric shock rod 240. After the slaughter is completed, the second rotating plate 310 is rotated and expanded, and the push plate 304 is pushed again to push the pig down to the second conveyor belt 231, and then the pig is transported out of the slaughter box 200 through the discharge port 221; When the pig is located on the top of the supporting plate 410, the first spring 412 is driven to contract under the pressure of the pig on the supporting plate 410, and the supporting plate 410 descends, which can drive the first piston plate 413 to move downward through the first connecting rod 411. The downward movement of the first piston plate 413 can press the second piston plate 513 downward through the gas, and the downward movement of the second piston plate 513 can press the third piston plate 521 downward through the gas, and then squeeze the gas at the bottom of the third piston plate 521 into the air cavity 611. After the gas enters the air cavity 611, it can enter the fixing rod 630 to press the fourth piston plate 521. When the plug plate 631 is squeezed, the fourth piston plate 631 can drive the conductive plate 620 to move by squeezing the positive electrode 621 and the negative electrode 622 through the extension rod 632, and then expand the distance between the positive electrode 621 and the negative electrode 622, reducing the resistance of the path, and the positive electrode 621 and the negative electrode 622 are connected in parallel with the electric shock rod 240 through the line on the same path. At this time, the voltage distributed at the positive electrode 621 and the negative electrode 622 is reduced, and the voltage at the electric shock rod 240 can be adjusted by the mass of the pig.

[0035] When the present invention is in use, the voltage output from the electric shock rod 240 can be adjusted according to the weight of the pig through the provided load-bearing component, adjustment component and conveying component, and then the corresponding voltage can be applied according to the pigs of different masses, so as to avoid the voltage being too small to quickly slaughter the pigs, and to avoid the voltage being too high to affect the meat quality and the slaughtering effect.

[0036] By setting up the sliding frame 510, when the pig is frightened by the electric shock at the electric shock rod 240, the shaking caused by the fright causes the movement of the second piston plate 513, and the second piston plate 513 can move a certain distance in the sliding frame 510 and then squeeze the sliding frame 510 to move, which can prevent the movement of the second piston plate 513 when the pig is frightened from affecting the distance between the positive electrode 621 and the negative electrode 622, thereby affecting the stability of the voltage at the electric shock rod 240.

[0037] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
