Description

Technical Field

[0001] The invention relates to the technical field of pig washing, in particular to an automatic pig washing machine for slaughtering pigs. Background Art

[0002] Hygiene management during the slaughter of live pigs is very important, as it affects the safety and quality of the final product. When the viscera are removed from the pig, some residues will remain in the body cavity, such as blood, tissue fragments, etc. These residues may become a breeding ground for microbial growth, so they need to be removed by flushing. Flushing can not only prevent microbial contamination, but also improve the color, taste and overall quality of the meat.

[0003] The slaughter of pigs is mainly carried out by driving the hook down on a hanging chain conveyor line to hook up the pigs, then lifting the pigs, cutting and removing the internal organs, cleaning them through a cleaning device, and then continuing to transport them for subsequent processing operations. The cleaning method of the cleaning device is that the hanging chain conveyor line drives the pigs to pass between two rotating roller brushes, which brush the passing pigs.

[0004] However, the following problems exist in the current pig flushing process: after the pig is slaughtered, its muscles will enter a period of rigor mortis, which is a natural process. Due to the depletion of adenosine triphosphate, the muscle fibers can no longer relax, causing the entire muscle group to become very tight and hard. In this process, the elasticity of the muscles is lost, so the chest and abdominal cavity of the pig that has been cut open cannot be kept open, so that the hook that only serves to lift the pig cannot open the pig's chest and abdominal cavity, which makes it impossible to effectively and comprehensively flush the cavity during the flushing process; secondly, the existing flushing method is mainly fixed-position flushing, which is prone to dead corners. Summary of the invention

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0032] like Figure 1 As shown, an automatic pig washing machine for slaughtering pigs includes a bottom plate 10 and a fixed plate 11; the fixed plate 11 is fixedly installed on the moving section of the hanging chain conveyor line, a pulling mechanism 2 is arranged on the fixed plate 11, and a flushing mechanism 3 is arranged on the bottom plate 10.

[0033] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the pulling mechanism 2 includes a fixed seat 20, and the fixed plate 11 is an inverted structure. Two left-right symmetrical fixed seats 20 are installed between the two vertical sections of the fixed plate 11 for sliding left and right. Support plates 21 are rotatably installed at the opposite ends of the two fixed seats 20. The opposite surfaces of the two support plates 21 are symmetrically rotatably installed with rotating shafts 25, and a circular ring 26 is fixedly installed on the rotating shaft 25, and a hook 22 is movably installed on the circular ring 26.

[0034] like Figure 1 and Figure 3 As shown, the flushing mechanism 3 includes a receiving plate 30, the receiving plate 30 is slidably installed on the upper end of the base plate 10, a No. 1 hydraulic cylinder 31 located in front of the receiving plate 30 is fixedly installed on the upper end of the base plate 10, the telescopic section of the No. 1 hydraulic cylinder 31 is fixedly connected to the receiving plate 30, a flushing portion 32 is provided at the front end of the receiving plate 30, and a swinging portion 33 for driving the flushing portion 32 to swing left and right is also provided on the receiving plate 30, and a limiting portion 34 is provided on the upper end of the base plate 10, which is located on the rear side of the receiving plate 30 and is used to limit the shaking of the support plate 21.

[0035] like Figure 1 As shown, the fixing plate 11 is provided with a tensioning portion 23 which cooperates with the movement of the receiving plate 30 to drive the two fixing seats 20 to move so as to open the thoracic and abdominal cavities of the pigs, and a locking portion 24 is provided between the fixing plate 11 and the receiving plate 30 to fix the fixing seat 20 after the movement.

[0036] During specific operation, the hanging chain conveyor line drives the pulling mechanism 2 to move to the lower part of the hanging chain conveyor line so as to hook up the live pig. When the pulling mechanism 2 moves to the lowest part of the hanging chain conveyor line, the support plate 21 is manually pulled forward to rotate it from a vertical state to a horizontal state. At this time, the hook 22 is manually passed through the legs of the live pig, and then the hanging chain conveyor line drives the fixed plate 11 and the fixed live pig to move and slowly rise to a high place. At this time, the support plate 21 rotates from a horizontal state to a vertical state under the self-weight of the live pig, and then the hanging chain conveyor line transports the lifted live pig to the existing external cutting device for abdominal cutting and removal of internal organs.

[0037] Then the hanging chain conveyor line moves the pig with caesarean section to the flushing mechanism 3, and limits the movement of the support plate 21 and the fixed plate 11 by the limit part 34. Then the external hydraulic pump is connected to the No. 1 hydraulic cylinder 31 through the external No. 1 conveying pipe, and the No. 1 hydraulic cylinder 31 is controlled to start so that it pushes the receiving plate 30 to move toward the pig, so that the flushing end of the flushing part 32 is inserted into the abdominal cavity of the pig. During the movement of the receiving plate 30, the tensioning part 23 will be driven to pull the legs of the pig to open the abdominal cavity of the pig. At the same time, the locking part 24 limits the movement of the fixed seat 20, so that the pig keeps the abdominal cavity in an open state, and then the abdominal cavity of the pig is flushed through the cooperation of the swinging part 33 and the flushing part 32.

[0038] like Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, the limiting portion 34 includes a limiting rod 340, and the upper end of the base plate 10 is fixedly installed with two limiting rods 340 that are symmetrical about the support plate 21 through a pillar, and the front and rear ends of the support plate 21 are rotatably installed with rollers 341 that are in contact with the limiting rods 340, and the rear end of the receiving plate 30 is fixedly installed with a connecting plate 342 at a position corresponding to the fixed plate 11, and the rear end of the connecting plate 342 is fixedly installed with two left-right symmetrical electromagnets 343.

[0039] During specific operation, when the hanging chain conveyor line drives the pulling mechanism 2 with the live pig to move toward the flushing mechanism 3, the support plate 21 will move between the two limit rods 340 to limit the rotation of the support plate 21 through the limit rods 340, and then the No. 1 hydraulic cylinder 31 will push the receiving plate 30 to move toward the live pig, and the receiving plate 30 will drive the electromagnet 343 to fit with the fixed plate 11 through the connecting plate 342, and then the electromagnet 343 will be energized to adsorb the fixed plate 11 to limit the movement of the fixed plate 11, thereby ensuring the stability of the live pig during the cleaning process and preventing the live pig from shaking and affecting the cleaning effect and the operation of the corresponding structure.

[0040] like Figure 1 , Figure 3 and Figure 5As shown, the tensioning part 23 includes an axis plate 230, and the axis plates 230 are fixedly installed on the left and right ends of the fixed plate 11. A bidirectional screw rod 231 that rotates and passes through the two axis plates 230 is arranged between the two vertical sections of the fixed plate 11, and the two fixed seats 20 are respectively threadedly connected with the two threaded sections of the bidirectional screw rod 231, and the receiving plate 30 is provided with an actuator for driving the bidirectional screw rod 231 to rotate.

[0041] like Figure 3 and Figure 5 As shown, the actuator assembly includes a spur gear 232, the right end of the bidirectional screw rod 231 is fixedly installed with the spur gear 232, and the front end of the receiving plate 30 is fixedly installed with a No. 2 hydraulic cylinder 233 at a position corresponding to the spur gear 232, and the telescopic section of the No. 2 hydraulic cylinder 233 slides through the receiving plate 30 and is fixedly installed with a rack 234 meshing with the spur gear 232.

[0042] like Figure 1 , Figure 3 and Figure 6 As shown, the locking portion 24 includes a roller shaft 240, and the roller shaft 240 is fixedly installed at both the front and rear ends of the fixed seat 20. A waist groove corresponding to the roller shaft 240 is opened on the fixed plate 11, and the roller shaft 240 slides through the corresponding waist groove. The front end of the fixed plate 11 is slidably installed with a square tube 241 with an open left end, and a slide plate 242 is slidably installed on the left end of the square tube 241. The square tube 241 is fixedly connected to the corresponding roller shaft 240 on the right fixed seat 20, and the slide plate 242 is fixedly connected to the corresponding roller shaft 240 on the left fixed seat 20. A limiting hole is opened at the front end of the square tube 241, and the limiting hole passes through the square tube 241, the slide plate 242 and the fixed plate 11, and a fixing member 4 for limiting the slide plate 242 from sliding in the square tube 241 is provided on the connecting plate 342.

[0043] like Figure 5 and Figure 6 As shown, the fixing member 4 includes a cylinder 40, and the rear end of the connecting plate 342 is fixedly installed with a cylinder 40 coaxial with the limiting hole, and a slide rod 41 cooperating with the limiting hole is slidably connected inside the cylinder 40, and a ball is rollingly installed at the rear end of the slide rod 41, and a compression spring 42 is installed between the front end of the slide rod 41 and the inner wall of the cylinder 40.

[0044] During specific operation, when the receiving plate 30 drives the electromagnet 343 to approach the fixed plate 11 through the connecting plate 342, the sliding rod 41 will contact the front end surface of the square tube 241 through the ball bearing and compress the compression spring 42 at the same time, and the movement of the receiving plate 30 will also drive the toothed section of the rack 234 to mesh with the spur gear 232, so as to drive the bidirectional screw rod 231 to rotate through the spur gear 232, and the bidirectional screw rod 231 will drive the two fixed seats 20 to move away from each other, and the fixed seat 20 will drive the support plate 21 and the roller shaft 240 to move away from each other, so as to pull the pig's legs. When the pig's abdominal cavity is opened, the rollers 240 move away from each other and pull the square cylinder 241 and the slide plate 242 respectively. The overall length of the square cylinder 241 and the slide plate 242 becomes longer. After the receiving plate 30 moves into place, the limiting holes on the square cylinder 241 and the limiting holes on the slide plate 242 are relatively connected and coaxial with the slide bar 41. The slide bar 41 moves backward under the action of the rebound force of the compression spring 42 and passes through the square cylinder 241, the slide plate 242 and the fixed plate 11 in sequence to limit the movement of the fixed seat 20, so that the pig's abdominal cavity remains open. At this time, the pig's abdominal cavity can be flushed.

[0045] After the flushing is completed, the No. 2 hydraulic cylinder 233 connected to the external hydraulic pump pushes the rack 234 to move backward, so that the toothed section of the rack 234 is away from the spur gear 232, and the moving distance is equal to the moving distance required for the slide bar 41 to separate from the square cylinder 241. At the same time, the electromagnet 343 is powered off to release the adsorption of the fixed plate 11. Then the No. 1 hydraulic cylinder 31 pulls the receiving plate 30 away from the pig, and the receiving plate 30 drives the slide bar 41 to separate from the square cylinder 241 through the connecting plate 342, the cylinder 40 and the compression spring 42. The cylinder 241 is reset, and the toothed section of the rack 234 is meshed with the spur gear 232 again. Then the No. 2 hydraulic cylinder 233 pulls the rack 234 forward and resets it, so as to drive the bidirectional screw rod 231 to rotate in the opposite direction through the spur gear 232, so that the two fixed seats 20 are close to each other. At this time, the abdominal cavity of the pig is not pulled and remains in a natural state. Then the hanging chain conveyor line drives the flushed pigs to move to the next processing area for subsequent processing, and the pigs to be flushed are moved to the flushing mechanism 3 for flushing processing.

[0046] like Figure 1 and Figure 2 As shown, the flushing portion 32 includes a slider 320, and the slider 320 is slidably installed up and down on the left side of the front end of the receiving plate 30, and two vertically symmetrical support plates 321 are fixedly installed on the left end of the slider 320, and a liquid inlet pipe 322 is rotatably installed between the two support plates 321, and the rear end of the liquid inlet pipe 322 is connected to a nozzle 323, and a driving component for driving the slider 320 to reciprocate up and down is arranged on the receiving plate 30.

[0047] like Figure 1 and Figure 2As shown, the drive assembly includes a bearing block. At the front end of the receiving plate 30, two symmetrically arranged bearing blocks are fixedly installed up and down. A reciprocating lead screw 324 is rotatably penetrated between the two bearing blocks. The slider 320 is threadedly connected to the reciprocating lead screw 324. At the front end of the receiving plate 30, a motor 325 is fixedly installed below the reciprocating lead screw 324. The output shaft of the motor 325 is fixedly connected to the reciprocating lead screw 324.

[0048] As Figure 1 and Figure 2 shown, the swinging part 33 includes a U-shaped plate 330. A U-shaped plate 330 is arranged on the front side of the slider 320. The liquid inlet pipe 322 is located between the two horizontal sections of the U-shaped plate 330. Waist-shaped slots are opened on both horizontal sections of the U-shaped plate 330. A shaft column that slidably penetrates the corresponding waist-shaped slot is fixedly installed on the liquid inlet pipe 322. A connecting plate 331 is fixedly installed at the right end of the vertical section of the U-shaped plate 330. At the front end of the receiving plate 30, a guiding assembly is provided for driving the liquid inlet pipe 322 to swing.

[0049] As Figure 1 and Figure 2 shown, the guiding assembly includes a rectangular plate 332. A rectangular plate 332 is fixedly installed at the front end of the receiving plate 30 on the right side of the reciprocating lead screw 324. A wavy slot 333 is opened at the front end of the rectangular plate 332. A guide post 334 that cooperates with the wavy slot 333 is rotatably installed at the rear end of the connecting plate 331.

[0050] During specific operation, the motor 325 drives the reciprocating lead screw 324 to rotate. The reciprocating lead screw 324 drives the liquid inlet pipe 322 and the spray head 323 to reciprocate up and down in the abdominal cavity of the live pig through the slider 320 and the support plate 321. An external water pump is connected to the liquid inlet pipe 322 through an external flexible pipe. When the liquid inlet pipe 322 reciprocates up and down, high-pressure water is sprayed through the spray head 323 to wash the abdominal cavity of the live pig. While the liquid inlet pipe 322 reciprocates up and down, it drives the connecting plate 331 to move simultaneously through the U-shaped plate 330. With the cooperation of the guide post 334 and the wavy slot 333 and the cooperation of the waist-shaped slot on the U-shaped plate 330 and the shaft column, the liquid inlet pipe 322 reciprocates left and right around the rotation point between it and the support plate 321 while reciprocating up and down. This enables the spray head 323 to reciprocate left and right while reciprocating up and down in the abdominal cavity of the live pig, so as to increase the flushing range of the spray head 323 for the abdominal cavity of the live pig, thereby improving the flushing effect on the live pig.
