Description

Technical Field

[0001] The invention belongs to the technical field of slaughtering machinery, and in particular relates to a three-point hemp making device for slaughtering pigs. Background Art

[0002] Pork, one of the earliest domesticated meats, is a widely consumed meat worldwide due to its high protein and vitamin content. To meet market demand, many farms slaughter and cut up whole pigs to provide the cleaned pork directly to the public, or further process the pork into meat products, improving meat consumption.

[0003] Traditionally, pig slaughter involves manual killing, a cruel method. Using knives to kill pigs can cause them to struggle violently, splashing blood onto workers and even injuring them, making it unsafe. Currently, another method involves driving the pigs directly into a stunner, where they are stunned by three taps. This method requires manual effort to constantly drive the pigs into the stunner chamber and force them forward using a saddle conveyor chain. Fearful of the pigs, they unconsciously retreat due to the friction of the saddle conveyor chain, necessitating constant manual pushing and shoving, which impacts feeding efficiency and wastes labor. Summary of the Invention

[0011] When the pedal is in the initial position, the upper end surface of the pedal is flush with the table surface of the driving platform, and the upper end surface of the pedal is higher than the inner bottom wall of the frame;

[0012] When a live pig passes over the pedal, the indexing drive member drives the pedal to swing to a maximum angular displacement, and the upper end surface of the swing end of the pedal is lower than the inner bottom wall of the frame.

[0013] As a further optimization scheme of the present invention, a pressure sensor is provided under the pedal, and the pressure sensor is fixed on the support plate, and the support plate is fixed on the shifting end of the shifting member. When the pedal is in the initial position, the support plate is located below the swinging end of the pedal, and the pressure sensor is in contact with the swinging end of the pedal. The pressure sensor is used to monitor whether there are live pigs passing over the pedal.

[0014] As a further optimization scheme of the present invention, a cone plate is provided behind the saddle conveyor chain along the conveying direction of the live pigs. The cone plate is fixed on the driving platform, and the width of the cone plate gradually increases, and the maximum width value of the cone plate is greater than the width value of the saddle conveyor chain.

[0015] As a further optimization solution of the present invention, a blocking component is further provided on one side of the cone plate, and the blocking component is used to block the pigs at the rear from continuing to move forward when the swing end of the pedal swings to the maximum angular displacement.

[0016] As a further optimization scheme of the present invention, the blocking assembly includes a fork step plate, a guardrail and a fork step drive assembly, the fork step plate is arranged on the inclined side of the cone plate, the fork step plate is fixedly connected to the indexing sub-shaft, the indexing sub-shaft is rotatably connected to the cone plate, the output end of the fork step drive assembly is transmission-connected to the indexing sub-shaft, the swinging end of the fork step plate is fixedly connected to the guardrail, the winding end of the guardrail is wound around the winding shaft and wound in the cone plate, and the winding shaft is rotatably connected to the cone plate.

[0022] Among them, by controlling the horizontal and tilted states of the pedal in the seating guide mechanism, the abdomen of the pig walking on the horizontal pedal is located above the saddle board. At this time, the pedal swings and tilts, causing the pig to slide forward toward the front of the tilted pedal, so that the pig naturally sits on the saddle board under the action of its own gravity, thereby realizing automatic feeding of the pig, and the pedal tilted forward prevents the pig from falling back;

[0023] Moreover, a cone plate is set above the driving platform, and the width of the cone plate gradually increases, and the maximum width of the cone plate is greater than the width of the saddle conveyor chain, so that the left and right legs of the pigs are naturally separated on both sides of the saddle conveyor chain, so that the pigs can ride on the saddle conveyor chain smoothly;

[0024] In addition, a blocking assembly is set on one side of the cone plate. The blocking assembly includes a fork step plate and a fence. When the pedal is tilted, the fork step plate swings away from the cone plate to stretch the fence plate to form a barrier to the pigs behind. After the pigs in the front are successfully transported to the area outside the pedal, the fence plate is reeled in to drive the pigs behind forward in an orderly manner.

[0033] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0034] like Figure 1 and Figure 2 As shown, the present invention provides a three-point hemp making device for slaughtering pigs, comprising:

[0035] The saddle conveying mechanism 12 includes a saddle conveying chain, which is used to transport the pigs to the electroanesthesia position in an orderly manner through the saddle plates in the saddle conveying chain;

[0036] The anesthetic mechanism 1 is used to stun the pigs transported to the anesthetic position with electric anesthesia;

[0037] Among them, along the conveying direction of pigs (with Figure 2(In the orientation shown, the pigs are conveyed from right to left.) A seating guide mechanism is provided on each side of the end of the saddle conveyor chain away from the hemp-making mechanism 1. These guide mechanisms are used to guide the moving pigs to sit in an orderly manner on the saddle plates of the saddle conveyor chain. This eliminates the need for manual pushing of the pigs, reducing manual intervention costs. The pigs are conveyed smoothly and orderly onto the saddle conveyor chain, improving pig conveying efficiency and ensuring the efficiency of subsequent hemp-making and corona treatment.

[0038] It should be noted that the existing anesthesia mechanism 1 mostly adopts a three-point anesthesia method, that is, after the pig enters the electric anesthesia position, the photoelectric monitoring system instructs the three electrodes to extend quickly and contact the area under the two ears and the heart of the pig respectively. The pig can be stunned after a few seconds of continuous electric shock. The time of electric shock can be adjusted according to the physique of the pig to ensure that the pig will not wake up before the next step of slaughter.

[0039] For example, see Figure 1 and Figure 2 As shown, the saddle conveyor chain is arranged on the frame 101 of the hemp making mechanism 1, and a driving platform 3 is fixedly arranged at the rear of the frame 101 along the conveying direction of the live pigs, wherein the uppermost end surface of the saddle in the saddle conveyor chain is lower than the abdomen of the live pigs walking on the driving platform 3, and the seating guide mechanism includes a pedal 13 and a transfer drive member, the output end of the transfer drive member is transmission-connected to the pedal 13, the pedal 13 is located in a give way groove 18 provided on the frame 101, and the rotating end of the pedal 13 is rotatably connected to the driving platform 3, and along the conveying direction of the live pigs, the swing end of the pedal 13 is located in front of the rotating end of the pedal 13;

[0040] When the pedal 13 is in the initial position, as shown in FIG. Figure 2 As shown, the upper end surface of the pedal 13 is flush with the table surface of the driving platform 3, and the upper end surface of the pedal 13 is higher than the inner bottom wall of the frame 101; at this time, since the upper end surface of the saddle in the saddle conveyor chain is lower than the abdomen of the pig walking on the driving platform 3, the pig will naturally walk above the saddle plate of the saddle conveyor chain when walking on the driving platform 3;

[0041] The pigs continue to walk, and when a pig passes on the pedal 13, that is, the entire weight of the pig is applied to the pedal 13, the indexing drive member drives the pedal 13 to swing to the maximum angular displacement, and the upper end surface position of the swinging end of the pedal 13 is lower than the inner bottom wall position of the frame 101, that is, the pedal 13 swings counterclockwise to an inclined position. At this time, the pigs' feet slide down along the inclined pedal 13 and naturally sit on the saddle plate of the saddle conveyor chain, thereby realizing orderly transportation of the pigs to the saddle conveyor chain, and the inclined pedal 13 lowers the supporting surface under the pigs' feet at a gentle angle, and the center of gravity of the body sinks slowly, avoiding panic or struggle caused by sudden weightlessness of the pigs' feet, reducing the secretion of stress hormones, and avoiding meat damage caused by stress; and the pedal 13 is inclined toward the front, so that the pigs can only slide forward along the inclined surface, avoiding the pigs from being stranded or retreating at the pedal 13, and ensuring that there is no congestion at the entrance of the conveyor chain.

[0042] For example, see Figure 1 、 Figure 2 and Figure 3 As shown, a pressure sensor 17 is provided below the pedal 13, and the pressure sensor 17 is fixed on the support plate 15, and the support plate 15 is fixed on the shift end of the shift member 16. When the pedal 13 is in the initial position, the support plate 15 is located below the swing end of the pedal 13, and the pressure sensor 17 is in contact with the swing end of the pedal 13. The pressure sensor 17 is used to monitor whether there are live pigs passing over the pedal 13.

[0043] When the pressure sensor 17 monitors that the weight of the pig on the pedal 13 reaches the weight of the whole pig, the shifting member 16 drives the support plate 15 to retreat to one side of the pedal 13, so that the pedal 13 is not supported by external force. At this time, under the drive of the indexing drive, the pedal 13 can be driven to swing to the maximum angular displacement in the yield groove 18 without interference from the support plate 15. After the whole pig is removed from the pedal 13, the indexing drive drives the pedal 13 in reverse to index to the initial position. At this time, the shifting member 16 drives the support plate 15 to return to its original position, so that the pressure sensor 17 is again in contact with the pedal 13.

[0044] It should be noted that the shifting member 16 is a hydraulic telescopic cylinder, an electric cylinder or an electric cylinder, which is not limited here, and the indexing driving member of the pedal 13 is a motor.

[0045] For example, see Figure 2 、 Figure 4 and Figure 5 Along the conveying direction of the live pigs, a cone plate 20 is provided behind the saddle conveyor chain. The cone plate 20 is fixed on the driving platform 3, and the width of the cone plate 20 gradually increases. The maximum width of the cone plate 20 is greater than the width of the saddle conveyor chain. Figure 5As shown, the cone plate 20 is a structure that gradually widens from right to left, so that when the live pig is driven up, the left and right legs of the pig are forked to the two sides of the cone plate 20 with the help of the cone plate 20, that is, when the live pig is driven forward, the left and right legs are naturally separated on both sides of the saddle conveyor chain, so that the left and right legs of the live pig are pre-positioned in the supporting areas on both sides of the saddle plate, avoiding the body from tilting or tipping over after sitting down due to leg crossing, closing or offset, ensuring that the live pig is stably seated on the saddle plate, reducing the behavior of crossing the legs, kicking randomly, etc., thereby ensuring that when the pedal 13 is tilted later, the live pig is naturally seated on the saddle plate.

[0046] Exemplarily, a blocking component is further provided on one side of the cone plate 20, and the blocking component is used to block the pigs behind from continuing to move forward when the swing end of the pedal 13 swings to the maximum angular displacement.

[0047] Continue reading Figure 5 、 Figure 6 and Figure 7 The blocking assembly includes a fork step plate 14, a fence 25 and a fork step drive assembly. The fork step plate 14 is set on the inclined side of the cone plate 20. The fork step plate 14 is fixedly connected to the indexing secondary shaft 19, and the indexing secondary shaft 19 is rotatably connected to the cone plate 20. The output end of the fork step drive assembly is transmission-connected to the indexing secondary shaft 19. The swing end of the fork step plate 14 is fixedly connected to the fence 25. The winding end of the fence 25 is wound around the winding shaft 24 and wound in the cone plate 20. The winding shaft 24 is rotatably connected to the cone plate 20. Figure 5 As shown, the pedal 13 is in the initial position, at which time the fork step plate 14 is attached to the inclined surface of the cone plate 20. When the pedal 13 tilts, the fork step drive assembly will drive the indexing subshaft 19 to rotate, causing the fork step plate 14 to rotate away from the cone plate 20, so that the fence 25 is stretched out to prevent the pigs at the rear from continuing to move forward; until the pigs in the front are transported away from the pedal 13, the pedal 13 returns to its initial position. At this time, the fork step drive assembly drives the indexing subshaft 19 to rotate in the opposite direction, so that the fence 25 is finally reeled back, until the fork step plate 14 swings in the opposite direction to the initial position, so as to continue to force the pigs at the rear to move forward.

[0048] It should be noted that the fence 25 is a steel coil, and a soft pad is provided on the surface of the steel coil to avoid scratching the pig's skin.

[0049] For example, Figure 5 and Figure 6 As shown, the fork step drive assembly includes a driving bevel gear 22 and a driven bevel gear 21. The rotating end of the pedal 13 is fixedly connected to the indexing main shaft 23, and the indexing main shaft 23 is rotatably connected in the give way groove 18. The driving bevel gear 22 is fixedly connected to the indexing main shaft 23, and the driving bevel gear 22 is meshed with the driven bevel gear 21. The driven bevel gear 21 is fixedly connected to the indexing secondary shaft 19.

[0050] For example, Figure 4 As shown, restraining baffles 11 are symmetrically arranged on both sides of the saddle conveyor chain. The area between the lowest end of the restraining baffles 11 and the saddle conveyor chain provides space for the pig's legs to move. When the pig is conveyed by the saddle conveyor chain, the pig's legs can move within a small range within the above space, preventing the pig from kicking and affecting its own conveying balance.

[0051] And as Figure 1 As shown, railings 2 are symmetrically arranged on both sides of the driving platform 3 along the conveying direction of the live pigs, so that when driving the live pigs, the live pigs on the driving platform 3 can only move along the walkway constrained by the railings 2, and a loading platform 31 is set at the rear end of the driving platform 3 to allow the live pigs to climb onto the driving platform 3 smoothly.

[0052] like Figure 1 As shown, a ventilation fan 4 is also provided above the frame 101, and the ventilation fan 4 is used to ventilate and cool the pigs transported in the frame 101 to prevent the pigs at the electric anesthesia position from being stunned and the pigs transported on the saddle conveyor chain at the rear from feeling uncomfortable due to the small internal space of the frame 101 and the stuffiness.

[0053] It should be noted that, when the device is in use, the live pigs are driven onto the driving platform 3 in an orderly manner. Under the interference of the cone plate 20, the left and right legs of the live pigs are naturally separated on both sides of the saddle conveyor chain. At this time, the abdomen of the live pig is higher than the upper end surface of the saddle plate. When the live pig steps on the pedal 13, the pressure sensor 17 monitors the overall weight of the live pig, and the shifting member 16 drives the support plate 15 to retract according to the electrical signal of the pressure sensor 17, so that the swing end of the pedal 13 swings without interference. At this time, driven by the motor, the indexing spindle 23 drives the pedal 13 to swing down to the maximum angular displacement. Under the action of its own gravity, the live pig slides forward along the pedal 13 and naturally sits on the saddle plate.

[0054] The indexing main shaft 23 is meshed with the driven bevel gear 21 through the driving bevel gear 22, so that the indexing secondary shaft 19 drives the fork step plate 14 to swing away from the cone plate 20, so that the fence 25 is stretched out, forming a barrier for the pigs behind. After the pigs in front are transported to the front area of ​​the pedal 13, the pedal 13 swings back to the initial position, and the support plate 15 is extended to the bottom of the pedal 13 by means of the shifting member 16, so that the pressure sensor 17 abuts against the pedal 13, and the fork step plate 14 also swings back to the position of fitting the cone plate 20, and the fence 25 is retracted, so that the pigs behind can continue to move forward.

[0055] After the live pigs transported on the saddle conveyor chain are transported to the electric anesthesia position, the live pigs are stunned by three-point anesthesia using the anesthesia mechanism 1 so that they do not feel pain when they are subsequently slaughtered.

[0056] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
