Description

Technical Field

[0001] The invention mainly relates to the field of slaughtering and conveying, in particular to a lifting and conveying device for slaughtering beef cattle. Background Art

[0002] At present, the slaughtering process for fattening cattle has been relatively automated. First, the beef cattle are stunned by electric shock or puncture equipment, and then they are bled, de-headed, de-hoofed, skinned, etc., and then the internal organs are removed, cut, and refrigerated or cut. The operations before and after skinning need to be changed, that is, the beef cattle hoisted with iron chains are replaced with hook hoisting. The use of this assembly line-style conveying device, combined with semi-automatic electric saws, winch skinning machines and visceral removal machines, can greatly reduce the degree of human participation in the beef cattle slaughtering process, and improve the efficiency and standardization of beef cattle slaughtering. However, combined with the current slaughtering process, the following problems still exist:

[0003] 1. Currently, the cattle entering the slaughtering line mainly rely on manual driving. However, the driving time for cattle varies according to individual differences, which leads to discontinuous feeding of the slaughtering line and makes the slaughtering line unable to operate at full capacity. At the same time, the operator needs to be on standby to drive the cattle, which consumes a lot of manpower.

[0004] 2. When bleeding beef cattle, it takes more than ten minutes, and the blood needs to be recovered. The current conveyor line is difficult to maintain the bleeding time, which affects the quality of beef. By extending the length of the conveyor rail to extend the bleeding time of beef cattle, the blood cannot be collected well.

[0005] 3. At present, the skinned cattle are hoisted on one leg, which requires manpower or other equipment to straighten the cattle when eviscerating and cutting in half, making the operation of eviscerating and cutting in half more complicated and inefficient. Moreover, manual participation in such large-scale sawing operations also becomes a safety hazard. Summary of the invention

[0006] In order to solve the deficiencies of the prior art, the present invention provides a lifting and conveying device for slaughtering beef cattle, which can make the slaughtering and conveying process of beef cattle more coherent, improve the continuity of beef cattle slaughtering, and at the same time improve the automation degree of beef cattle slaughtering and reduce safety hazards.

DETAILED DESCRIPTION

[0029] The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art may make various changes or modifications to the present invention, and these equivalent forms also fall within the scope limited by the application.

[0030] like Figure 1-9 As shown, the lifting and conveying device for slaughtering beef cattle of the present invention comprises a guiding device 1, a preceding conveying device 2 and a subsequent conveying device 3. The guiding device 1 is used as a buffer mechanism for beef cattle to be slaughtered. By temporarily storing the beef cattle to be slaughtered in the guiding device 1, the rate at which the beef cattle enter the slaughtering line is kept consistent, so that the preceding conveying device 2 can continuously convey the beef cattle to be slaughtered, making the efficiency of the entire slaughtering line higher. The preceding conveying device 2 is sequentially provided with the processes of stabbing and bleeding, decapitation, and skinning, and the subsequent conveying device 3 is sequentially provided with the processes of opening the cavity to separate the internal organs, splitting in half, and inspection. The beef passing through the subsequent conveying device 3 is cut and packaged or temporarily stored in a cold storage.

[0031] The guide device 1 includes a buffer disk 11, on which a plurality of buffer positions 12 are evenly arranged in a circle, and the buffer position 12 can only accommodate one cow, and a rotation drive device is installed in the center of the buffer disk 11. Specifically, the buffer disk 11 is annular, and baffles are arranged on the inner and outer sides of the buffer disk 11, and the baffles are fixed to the ground and do not rotate with the buffer disk 11. The outer baffle is fixed to the ground by expansion bolts, and the inner baffle is connected to the outer baffle at the top by a connecting rod. The outer baffle has an opening at a position corresponding to the adjustment fence 13 and the electric shock channel 16 described below. In this embodiment, the rotation drive device is driven by a reduction motor, and the middle part of the buffer disk 11 has a rotating shaft, which is supported at the bottom of the buffer disk 11 by a plurality of connecting arms. The buffer disk 11 is driven by the reduction motor driving the rotating shaft. Further, the reduction motor adopts a stepping motor, and each time it rotates through a distance of a buffer position 12, the beef cattle in the buffer position 12 are released.

[0032] An adjustment fence 13 corresponding to the buffer position 12 is installed on one side of the buffer tray 11, and the adjustment fence 13 serves as a front guide device for driving beef cattle into the buffer position 12. A pushing device 14 is arranged at the front end of the adjustment fence 13, and the end of the adjustment fence 13 is an entrance. The adjustment fence 13 also only allows one beef cattle to enter, and the staff pulls the beef cattle from the entrance into the adjustment fence 13. A sliding gate can be installed at the entrance. Furthermore, the pushing device 14 includes a push plate 141, and a scissor-type pushing mechanism 142 is arranged between the push plate 141 and the adjustment fence 13, and the power source of the scissor-type pushing mechanism 142 is a hydraulic cylinder. The scissor-type pushing mechanism 142 can be extended by the extension of the hydraulic cylinder, so that the beef cattle can be pushed from the adjustment fence 13 into the buffer position 12. A rotation drive mechanism 15 is installed at the bottom of the adjustment fence 13, and the rotation drive mechanism 15 drives the adjustment fence 13 to rotate so that the entrance and the buffer position 12 are docked. In this embodiment, the bottom of the adjustment fence 13 has a turntable, and the rotation drive mechanism 15 adopts a reduction motor, which drives the turntable to rotate through the reduction motor, thereby driving the adjustment fence 13 to rotate. A pair of sensors are installed on the turntable. When the reduction motor drives the adjustment fence 13 to rotate so that it triggers the sensor, the entrance of the adjustment fence 13 can be directed toward the buffer position 12 or in the opposite direction of the buffer position 12, that is, the rotation angle of the adjustment fence 13 is 180 degrees. When driving the beef cattle into the buffer position, the beef cattle are driven into the adjustment fence 13, at this time, the cattle head faces the pushing device 14, and then the fence door is closed, and the adjustment fence 13 is controlled to rotate 180 degrees so that the entrance faces the buffer position 12, and then the pushing device 14 is controlled to extend, and the beef cattle are pushed back into the buffer position 12.

[0033] The other side of the buffer tray 11 is provided with an electric shock channel 16, and the preceding conveying device 2 is installed above the electric shock channel 16. The electric shock channel 16 allows only one cow to pass through. When the cow enters the electric shock channel 16, the cow is shocked on the forehead by an electric shock gun to be stunned, and then the preceding conveying device 2 is used to lift the cow. Furthermore, a pushing mechanism similar to the pushing device 14 can be installed on the inner side of the buffer tray 11 where the electric shock channel 16 is located, so as to assist in driving the cow from the buffer position 12 into the electric shock channel 16.

[0034] Specifically, the preceding conveying device 2 includes a hoisting rail 21, on which a plurality of hoisting chains 22 are slidably arranged. The top of the hoisting chain 22 has a pulley slidably connected to the hoisting rail 21, and the bottom of the hoisting chain 22 is a chain. After the electric shock and stunning of the beef cattle is completed, the hoisting chain 22 is wound around one of the hind hooves (right hind hooves) of the beef cattle, and the beef cattle can be lifted after being conveyed. Further, the hoisting rail 21 includes a lifting rail 211, a front docking rail 212, a plurality of parking rails 213, a rear docking rail 214 and a conversion rail 215 arranged in sequence. The lifting rail 211 is located above the electric shock channel 16, and the electric shock channel 16 is a high platform. When the lifting rail 211 lifts the beef cattle, it can drive the beef cattle to be lifted out of the electric shock channel 16. By driving the conveyance of the hoisting chain 22 on the lifting rail 211, the beef cattle can be easily lifted. The conversion rail 215 is connected with the lifting rail 211 by a circulating rail to form a closed loop, so that the hoisting chain 22 can be circulated and driven to continuously lift the beef cattle. A front drive belt 23 is arranged above the lifting rail 211, the front docking rail 212, the plurality of parking rails 213, the rear docking rail 214 and the conversion rail 215. In this embodiment, the front drive belt 23 of the lifting rail 211 and the conversion rail 215 is the same drive belt, which is tensioned by a plurality of guide wheels, one of which is equipped with a servo motor. The front docking rail 212, the plurality of parking rails 213 and the rear docking rail 214 are all provided with independent drive belts. A plurality of paddles 24 are arranged in an array on the front drive belt 23, and the paddles 24 cooperate with the top of the hoisting chain 22, and the upper frame of the hoisting chain 22 is pushed by the paddles 24, thereby driving the hoisting chain 22 to run on different tracks. Specifically, the parking rails 213 in this embodiment are arranged in a horizontal array. The parking rails 213 are used for the bleeding process. The cattle are allowed to rest on the parking rails 213 for more than ten minutes, so that the cattle blood can be evenly released. The arrangement of multiple parking rails 213 can give the slaughtered cattle sufficient buffer time for bleeding, without the need for progressive conveying on the conveyor line to ensure the bleeding time. At the same time, it can also ensure good acceptance of the cattle blood, and avoid cattle blood contaminating the ground and wasting.

[0035] The end of the lifting rail 211, the two ends of the parking rail 213 and the front end of the conversion rail 215 are all equipped with a push cylinder 25, and the front end of the piston rod of the push cylinder 25 has a one-way piece 26. The push cylinder 25 pushes the lifting chain 22 to transfer between different rails through the one-way piece 26. Specifically, the push cylinder 25 at the end of the lifting rail 211 and the end of the parking rail 213 extends toward the downstream direction, and the one-way piece 26 at the end of the lifting rail 211 and the end of the parking rail 213 can only swing toward the downstream direction. The push cylinder 25 at the front end of the parking rail 213 and the front end of the conversion rail 215 swings toward the upstream direction, and the one-way piece 26 at the front end of the parking rail 213 and the front end of the conversion rail 215 can only swing toward the downstream direction. The one-way piece 26 has a sensor. When the one-way piece 26 is triggered, the controller controls the push cylinder 25 to move, and completes the push of the lifting chain 22 to change its track. Specifically, taking the track change from the lifting rail 211 to the front docking rail 212 as an example, when the lifting chain 22 on the lifting rail 211 is driven to the end by the front drive belt 23 above it, the lifting chain 22 pushes the one-way plate 26 to bend downstream and move to the rear side of the one-way plate 26, and then the push cylinder 25 extends to push the lifting chain 22 to move to the front docking rail 212 for temporary storage. The push cylinder 25 pushes each lifting chain 22 to complete a track change, and the front drive belt 23 above the front docking rail 212 steps the distance between the two paddles 24, so that the beef cattle hoisted by the lifting chain 22 are neatly arranged on the front docking rail 212. The front docking rail 212 and the rear docking rail 214 are both provided with a lateral displacement mechanism 27, and the front docking rail 212 and the rear docking rail 214 can be moved horizontally through the drive of the lateral displacement mechanism 27, so as to dock with different parking rails 213. When the front docking rail 212 transfers the cattle hoisted thereon, it is pushed by the push cylinder 25 placed at the front end of the parking rail 213, and at this time, the initial state of the push cylinder 25 is the extended state. When the hoisting chain 22 triggers the one-way piece 26, the push cylinder 25 contracts once to complete the transfer of the hoisting chain from the front docking rail 212 to the parking rail 213. When the cattle are transferred from the front docking rail 212 to the parking rail 213, the front drive belt 23 above the front docking rail 212 steps to move the front hoisting chain 22 to the downstream of the one-way piece 26, and the push cylinder 25 on the front side of the parking rail 213 contracts to pull the hoisting chain 22 onto the parking rail 213, and the front drive belt 23 above the parking rail 213 steps to transport the hoisting chain 22 to the next position. The transfer of the beef cattle hoisted by multiple hoisting chains 22 to the parking rail 213 is completed by alternating steps of the front driving belt 23 above the front docking rail 212 and the front driving belt 23 above the parking rail 213 in coordination with the contraction of the pushing cylinder 25.When the parking rail 213 is used to transfer beef cattle to the rear docking rail 214, the front driving belt 23 above the parking rail 213 is stepped to move the front hoisting chain 22 to the downstream of the one-way plate 26, and the pushing cylinder 25 at the end of the parking rail 213 is extended once to push the hoisting chain 22 to the rear docking rail 214, and the front driving belt 23 above the docking rail 214 is stepped to transport the hoisting chain 22 to the next position. The front driving belt 23 above the parking rail 213 and the front driving belt 23 above the rear docking rail 214 are alternately stepped, and the extension of the pushing cylinder 25 is coordinated to complete the transfer of beef cattle hoisted by multiple hoisting chains 22 to the rear docking rail 214. When the rear docking rail 214 is used to transfer beef cattle to the conversion rail 215, the front drive belt 23 above the rear docking rail 214 moves forward and moves the front hoisting chain 22 to the downstream of the one-way plate 26. The front push cylinder 25 of the conversion rail 215 contracts once to push the hoisting chain 22 from the rear docking rail 214 to the conversion rail 215. The front drive belt 23 above the conversion rail 215 moves forward and transports the hoisting chain 22 to the next position. The front drive belt 23 above the rear docking rail 214 and the front drive belt 23 above the conversion rail 215 move forward alternately, and the push cylinder 25 contracts to complete the transfer of beef cattle hoisted by multiple hoisting chains 22 to the conversion rail 215.

[0036] Specifically, the lateral displacement mechanism 27 includes a top hanger body 271, and an adjustment rail 272 perpendicular to the front docking rail 212 and the rear docking rail 214 is installed at the bottom of the top hanger body 271. A synchronous belt driving mechanism 273 is arranged on one side of the adjustment rail 272. The front docking rail 212 and the rear docking rail 214 are correspondingly slidably arranged on the adjustment rail 272. Driven by the synchronous belt driving mechanism 273, the front docking rail 212 and the rear docking rail 214 can slide parallel to the adjustment rail 272, so as to dock with different parking rails 213. A point on the synchronous belt of the synchronous belt driving mechanism 273 is fixedly connected to the top of the corresponding front docking rail 212 or rear docking rail 214, so that the synchronous belt mechanism can be used to drive the front docking rail 212 or the rear docking rail 214 to move accurately.

[0037] The subsequent conveying device 3 includes a conveying rail 31, the front end of the conveying rail 31 overlaps with the rear end of the conversion rail 215, a plurality of hanging frames 32 are slidably installed on the conveying rail 31, a rear conveyor belt 33 is arranged above the conveying rail 31, and a plurality of paddles 34 are arranged in an array on the rear conveyor belt 33, the paddles 34 cooperate with the hanging frames 32, and driven by the rear conveyor belt 33, the paddles 34 can be used to push the hanging frames 32 thereon to slide along the conveying rail 31, thereby completing the transportation of beef cattle. The bottom of the hanging frame 32 has a sleeve 35, a 90-degree spiral groove is provided on the side wall of the sleeve 35, a lifting frame 36 is slidably installed in the sleeve 35, the lifting frame 36 has a limit column 361 slidably connected to the spiral groove, a spring 37 is provided between the lifting frame 36 and the sleeve 35, and the lifting frame 36 has cantilevers at both ends, and hooks 38 are installed on both sides of the bottom of the cantilever of the lifting frame 36. When the beef cattle are not hung on the hook 38, the lifting frame 36 is lifted to the highest point under the elastic action of the spring 37, and the lifting frame 36 is parallel to the conveying rail 31. When the beef cattle are hung on the hook 38, the lifting frame 36 is at the lowest point under the action of gravity, and the lifting frame 36 is perpendicular to the conveying rail 31. The top and bottom of the spiral groove on the sleeve 35 are both provided with horizontal parts. When the lifting frame 36 is at the highest point under the elastic action of the spring 37, the limiting column 361 is stuck in the horizontal part of the top of the spiral groove, so as to limit the position of the lifting frame 36. After the legs of the beef cattle are hung, the lifting frame 36 is pushed, so that the lifting frame 36 rotates a small angle and then descends along the spiral groove under the action of gravity. The setting of the horizontal part at the top ensures the stability of the lifting frame 36 when the beef cattle are hung. Similarly, the horizontal part at the bottom plays the same role, and when the beef cattle are taken down, it can prevent the lifting frame 36 from being lifted up quickly to cause safety hazards.

[0038] Specifically, when the present invention is used to transport slaughtered beef cattle, the coordination process of each part is as follows:

[0039] First, the beef cattle are driven into the adjustment fence 13, and then the rotating drive mechanism 15 is controlled to drive the adjustment fence 13 to rotate 180 degrees, so that the entrance is facing the buffer position 12. Then the pushing device 14 is controlled to extend, and the beef cattle are pushed into the buffer position. Then the rotating drive device drives the buffer plate 11 to rotate the distance of a buffer position 12, and the next buffer position 12 is moved to the position corresponding to the adjustment fence 13 to wait for the beef cattle to take over. With the step-by-step rotation of the buffer plate 11, the beef cattle in the buffer position 12 can be guided into the electric shock channel 16 in sequence. After the beef cattle are stunned in the electric shock channel 16, the right hind leg of the beef cattle is helped by the hoisting chain 22 above the lifting rail 211, and it is hoisted by the drive of the front drive belt 23. Then the neck is cut and bleeding is performed, and the beef cattle are transferred to the parking rail 213 through the front docking rail 212 and placed still. With the movement of the lateral displacement mechanism 27, the front docking rail 212 completes the docking of the lifting rail 211 with different parking rails 213, and transfers the bled beef cattle to the parking rail 213 for temporary storage. The rear docking rail 214 receives the beef cattle that have been bled, and the movement of the lateral displacement mechanism 27 drives the rear docking rail 214 to complete the connection between different parking rails 213 and the conversion rail 215. Then, the head and hoof processing is completed on the conversion rail 215, and then the beef cattle are docked with the subsequent conveying device 3, and the left and right hind hooves of the beef cattle are hung on the hooks 38 at the bottom of the hanging frame 32 in turn, and then the hanging frame 32 is pushed, so that the limit column 361 is separated from the horizontal part and guided to fall in the spiral groove, so that the hanging frame 32 is transformed from a vertical state with the conveying rail 31 to a horizontal state, so as to facilitate the subsequent evisceration and half-cutting operations. Finally, after the inspection is completed on the conveying rail 31, it is cut or stored in the warehouse for refrigeration.
