Abstract
Description
Technical Field
[0001] This invention relates to the field of slaughtering equipment technology, and in particular to a pig transportation device for slaughterhouses. Background Technology
[0002] In the pig slaughtering and processing industry, the transfer of live pigs to the bleeding or stunning station is an essential and crucial step. Because pigs are large and prone to stress in the slaughter environment, traditional manual herding is inefficient and easily leads to injury. Therefore, slaughterhouses commonly use suspended rails and conveyor systems to secure the pigs' legs before transporting them on a mechanized assembly line, ensuring the continuity of slaughtering operations and on-site safety.
[0003] In existing technologies, some pig slaughtering conveyor systems use a motor-driven transmission belt to move hooks along a track, and a rope loop structure for binding the pig's feet is installed at the bottom of the hook. It mainly utilizes a fixed rigid boom and ordinary ropes to hang and transport live pigs.
[0004] The existing devices have several shortcomings in practical applications: First, the suspension end lacks a vertical pull-out structure, making manual leg hooking and lifting operations extremely laborious when dealing with pigs of different sizes; Second, the rope loop control structure is rudimentary and lacks physical restraints, making it easy for the rope to become overly tight or slip off when the pig struggles; Third, the entire conveying path lacks anti-sway and buffering mechanisms, and the violent twisting of the pig can cause the suspension system to sway significantly, which can easily damage transmission components and seriously threaten the personal safety of on-site operators. Summary of the Invention
[0005] (a) Technical problems to be solved
[0006] To address the shortcomings of existing technologies, this invention provides a pig transport device for slaughterhouses, aiming to solve the technical problems of poor adaptability of suspension and hanging, resulting in laborious manual operation; poor control of rope release and retraction, which easily leads to slippage or excessive strangulation; and the struggle of pigs during transport causing significant shaking of the suspension system, thereby causing damage to transmission components and safety hazards to on-site personnel.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, the present invention provides the following technical solution:
[0009] A pig transport device for a slaughterhouse includes: a frame support system comprising multiple columns and a suspension rail mounted on top of the columns; a pulley assembly slidably mounted on the suspension rail; a drive mechanism mounted on a partial transmission section of the suspension rail and connected to the pulley assembly for driving the pulley assembly to move along the rail; a suspension module suspended below the pulley assembly for suspending and fixing the pig's feet, the suspension module having a vertically retractable structure and a retractable and releaseable rope at its bottom; and an anti-sway and anti-deviation limiting system located in the lower middle part of the columns, including a buffer assembly and a grating sensor; the grating sensor detects the swaying amplitude of the pig in the suspended state, and the buffer assembly extends inward into the channel according to the detection signal from the grating sensor to block, buffer, and limit the swaying pig.
[0010] Preferably, the frame support system further includes a gantry column connected laterally and a side arm with an arc-shaped end. The bottom surfaces of the gantry column and the side arm are fixedly connected to the suspension guide rail through multiple connecting seats, so that the suspension guide rail forms a continuous circular conveying track with the beginning and end connected, so as to ensure the cyclical continuity of the conveying operation.
[0011] Preferably, the drive mechanism includes a transmission section guide rail connected to the suspension guide rail, a base is fixed on one side of the transmission section guide rail, and a servo motor is mounted on the base; a transmission wheel is connected to the output shaft of the servo motor, and a drive belt that abuts against the pulley assembly is sleeved on the outer circumference of the transmission wheel; a protective cover is provided for the transmission wheel and the drive belt.
[0012] Preferably, the drive mechanism further includes a strut fixed on the transmission section guide rail, with a pressure plate abutting against the back of the drive belt below the strut, and an adjusting bolt threaded through the strut, the bottom end of which is connected to the pressure plate; by rotating the adjusting bolt, the pressure plate can be driven to move up and down, thereby precisely adjusting the contact tension between the drive belt and the pulley assembly in a mechanical dimension, ensuring the stability of the transmission.
[0013] Preferably, the pulley assembly includes a slide seat straddling the suspension guide rail, with multiple movable wheels rotatably mounted on both sides of the slide seat and rolling on the track surface of the suspension guide rail; a downwardly extending suspension rod is fixedly connected to the bottom of the slide seat, and a boom for hanging components is hinged to the bottom end of the suspension rod, the hinge structure allowing the boom to deflect within a small range in accordance with the direction of force.
[0014] Preferably, the top of the suspension module is provided with a lifting ring, and the suspension module is attached to the boom through the lifting ring; the suspension module contains a winding module and a downwardly extending suspension rope, the upper end of the suspension rope is wound or movably threaded through the winding module, so that the suspension rope can be pulled and stretched vertically through the winding module to adapt to the loading requirements of different body shapes and lifting heights.
[0015] Preferably, the lower end of the hoisting rope is fixedly connected to a retraction module, and a geared motor and an electronic control button for manual operation are installed on the side wall of the retraction module. The sling is threaded through the retraction module and connected to the transmission output end of the geared motor. The electronic control button issues a command to control the geared motor to rotate forward and backward, thereby realizing the retraction and fixing or loosening of the sling coil. Furthermore, a stop block is provided at the bottom opening of the retraction module. When the sling is retracted and tightened around the pig's leg, the stop block adheres to the surface of the pig's limb and forms a mechanical stop and limit.
[0016] Preferably, the buffer assembly includes a back plate that is laterally spanned and fixed between adjacent columns, and a long strip-shaped buffer plate is arranged parallel to the side of the back plate facing the transport channel; the back plate and the buffer plate are connected by at least one servo cylinder and at least one guide telescopic rod; the servo cylinder is used to provide the driving force for the buffer plate to be translated and pushed out, and the guide telescopic rod is used to guide and support the translation process of the buffer plate.
[0017] Preferably, the grating sensor is installed on the column near the side wall of the transport channel to form a photoelectric detection surface; the grating sensor is electrically connected to the servo cylinder. When the grating sensor detects that the pig's shaking caused by struggling has cut off the light beam and exceeded the limited working area, it sends a trigger signal to the servo cylinder, causing the servo cylinder to extend and push the buffer plate into the channel to physically support and limit the excessive shaking of the pig.
[0018] Compared with the prior art, the beneficial effects of the present invention are:
[0019] This invention incorporates a retractable and extendable winding structure within the suspension module, allowing the lifting rope to be adjusted vertically. This structure adapts to the lifting height requirements of pigs of different sizes, reduces the physical exertion of operators during leg-hanging and lifting operations, and improves the convenience of on-site loading operations.
[0020] This invention utilizes a geared motor in the retraction module to control the contraction and relaxation of the rope, and adds a stop block at the bottom opening. When the rope tightens around the pig's leg, the stop block adheres to the surface of the pig's limb to form a mechanical barrier, preventing the rope from becoming excessively tight or slipping off due to the pig's struggle, thus ensuring the stability of the suspension during transportation.
[0021] This invention introduces an anti-sway and anti-deviation limiting system, consisting of a buffer assembly and a grating sensor, added to the lower middle part of the column. When the grating sensor detects that the suspension system is swaying due to the pig's struggle and exceeds the limited area, a servo cylinder drives the buffer plate to extend inward, providing timely physical blocking and cushioning for the swaying pig. This prevents the suspension system from swinging excessively, protects the upper transmission components from impact damage, and improves the safety of the working environment.

[0035] The transmission connection between the drive mechanism and the pulley assembly: such as Figure 2 and Figure 3 As shown, the pulley assembly 7 is slidably mounted on the suspension guide rail 4; the drive mechanism 6 is mounted on a partial transmission section of the suspension guide rail 4 and is connected to the pulley assembly 7 for transmission; the drive mechanism 6 includes a transmission section guide rail 61 parallel to the suspension guide rail 4, a base 62 is fixed on one side of the transmission section guide rail 61, and a servo motor 63 is mounted on the base 62; the output shaft of the servo motor 63 is connected to a transmission wheel 64, and a drive belt 65 is sleeved on the outer circumference of the transmission wheel 64. The drive belt 65 abuts against the top of the pulley assembly 7, and drives the pulley assembly by friction transmission. Part 7 moves along the track; at the same time, the outer cover of the transmission wheel 64 and the drive belt 65 is equipped with a protective cover 69; in order to adjust the tension of the drive belt 65, a cross seat 67 is also fixed on the transmission section guide rail 61, and a pressure plate 66 is provided below the cross seat 67, which abuts against the back of the drive belt 65; an adjusting bolt 68 is threaded through the cross seat 67, and the bottom end of the adjusting bolt 68 is connected to the pressure plate 66; by rotating the adjusting bolt 68, the pressure plate 66 is driven to move up and down, thereby adjusting the tension of the drive belt 65 in a mechanical dimension.
[0036] Combination Figure 4As shown, the pulley assembly 7 includes a slide block 72 spanning the suspension guide rail 4. Multiple movable wheels 73 are rotatably mounted on both sides of the slide block 72, and the movable wheels 73 roll on the track surface of the suspension guide rail 4. A downwardly extending suspension rod 71 is fixedly connected to the bottom of the slide block 72, and a boom 74 is hinged to the bottom end of the suspension rod 71. This hinged structure allows the boom 74 to deflect slightly when under force, avoiding local stress concentration caused by rigid connection.
[0037] The telescopic and retractable structure of the suspension module: such as Figures 4 to 7 As shown, the suspension module 8 is attached below the pulley assembly 7 to suspend and fix the pig's feet; the top of the suspension module 8 is equipped with a lifting ring 81, which is used to hang the lifting arm 74; the suspension module 8 integrates a winding module 82 and a downward-extending lifting rope 83; the upper end of the lifting rope 83 passes through and is wound inside the winding module 82, allowing the operator to pull and extend the lifting rope 83 vertically to adapt to changes in lifting height; the lower end of the lifting rope 83 is fixedly connected to a take-up and release module 84. A geared motor 85 and an electronic control button 88 for manual operation are installed on the side wall of module 84; a rope 86 is provided at the bottom, which is inserted into the take-up and release module 84 and connected to the transmission output end of the geared motor 85; the geared motor 85 is controlled to rotate forward and backward by operating the electronic control button 88 to realize the mechanical contraction and release of the rope 86; a stop block 87 is provided at the bottom opening of the take-up and release module 84.

[0038] The linkage mechanism of the anti-sway and anti-deviation limit system: such as Figure 8 and Figure 9 As shown, the system is located in the lower middle part of the column 1; the buffer assembly 9 includes a back plate 91 that is horizontally fixed between adjacent columns 1, and a long strip buffer plate 92 is arranged parallel to the side of the back plate 91 facing the transport channel; a servo cylinder 93 and a guide telescopic rod 94 are connected between the back plate 91 and the buffer plate 92; the servo cylinder 93 provides the thrust for the translation of the buffer plate 92, and the guide telescopic rod 94 provides the guide support for the translation process; the grating sensor 10 is installed on the column 1 near the side wall of the transport channel and forms an electrical communication connection with the servo cylinder 93.
[0039] The working principle and operation procedure of the device of the present invention are as follows:
[0040] Hanging stage: After the pig enters the hanging station, the operator pulls down the release module 84, and the winding module 82 releases the suspension rope 83 to reduce the height; then the rope 86 is put into the pig's hind leg, the electric control button 88 is pressed, the reduction motor 85 starts and tightens the rope 86; when the rope 86 is tightened to the point that the stop block 87 abuts against the surface of the pig's leg, the contraction stops, and the mechanical limit and suspension fixation are completed;
[0041] Conveying stage: Start the servo motor 63 to drive the transmission wheel 64 and drive belt 65 to rotate; drive belt 65 pushes the pulley assembly 7 to roll forward along the suspension guide rail 4, driving the suspension module 8 and the pigs it is carrying to move to the next process.
[0042] Anti-sway buffering stage: During transport, if the pig struggles violently, causing the suspension module 8 to sway significantly, the pig's body cuts off the detection beam of the grating sensor 10; the grating sensor 10 then sends a trigger electrical signal to the servo cylinder 93; the servo cylinder 93 quickly extends, pushing the buffer plate 92 to move inward into the channel; the buffer plate 92 contacts the pig's body, providing physical obstruction and buffering, limiting further swaying of the suspension system; after the swaying amplitude decreases and the grating detection returns to normal, the servo cylinder 93 drives the buffer plate 92 to reset and retract;
[0043] Unloading stage: The pigs are transported to the designated unloading station. The operator presses the electric control button 88 again, the reduction motor 85 reverses, the rope 86 is loosened and untied, and the entire transportation and unloading process is completed.
[0044] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
[0045] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention.
