Description

Technical Field

[0001] The present invention relates to the technical field of animal husbandry, and more specifically, to a sheep shearing fixation device with an automatic adjustment function. Background Art

[0002] In the sheep breeding industry, the shearing operation is a key link to ensure the quality of wool and the health of sheep. During the traditional shearing process, sheep are prone to struggle violently due to fear or discomfort, which not only increases the operation risk but also may cause economic losses due to the wool being trampled and polluted.

[0003] During the traditional shearing process, sheep are prone to struggle violently due to fear or discomfort, which not only increases the operation risk but also may cause economic losses due to the wool being trampled and polluted. Therefore, it is necessary to use a fixation device to fix the sheep. For example, a Chinese patent with the application number CN202420080276.4, a sheep shearing fixation frame, belongs to the technical field of shearing devices, including a shearing table. A head fixation mechanism is arranged on one side of the top surface of the shearing table. Two grooves are symmetrically opened on the top surface of the shearing table. Transverse grooves are opened on both inner walls of the grooves. Threaded rods are rotatably connected to both inner walls of the two grooves. Two foot pads for placing the limbs of the sheep are threadedly sleeved on the circumferences of the two threaded rods. Connecting plates are fixedly installed on both side surfaces of each foot pad. Cylinders are fixedly installed on the opposite side surfaces of every two connecting plates. The piston rod of each cylinder penetrates through the connecting plate and is fixedly connected with an arc-shaped block for fixing the limbs of the sheep. The arc-shaped blocks are all arranged above the foot pads. Each connecting plate and cylinder are arranged in the inner cavity of the transverse groove. This sheep shearing fixation frame solves the problem that the limbs of sheep are prone to kicking randomly during trimming and improves the safety of workers during work.

[0004] Although the above application can fix the sheep, it lacks an automatic adjustment function, resulting in the need for repeated fixation work for each sheep, thereby reducing the shearing efficiency of sheep. Summary of the Invention

[0005] 1. Technical Problem to be Solved: Although the prior art can fix the sheep, it lacks an automatic adjustment function, resulting in the need for repeated fixation work for each sheep, thereby reducing the shearing efficiency of sheep.

[0006] In view of the problems existing in the prior art, the present invention provides a sheep shearing and immobilizing device with an automatic adjustment function. It locates the position of the sheep through an infrared sensor, and the PLC controller automatically adjusts the head restraint mechanism. The head restraint is driven by a first telescopic rod to drive the side plate, and the pressure sensor triggers the movable limit plate, which is buffered by a spring to avoid damage. The four limbs are fixed by adjusting the position of the mounting block through the fourth telescopic rod and the fifth telescopic rod. The third telescopic rod drives the sliding block, and the pressure triggers the motor to drive the gear transmission, so that the adaptive splint containing the tension spring fixes the four limbs, thereby realizing automatic adjustment and flexible restraint, taking into account safety and body type adaptability, and improving the efficiency of shearing operations.

[0019] 3. Beneficial effects

[0020] Compared with the prior art, the advantages of the present invention are as follows:

[0021] (1) In this solution, the sheep are driven into the installation groove. When the infrared sensor on the side of the side plate detects the sheep, the PLC controller inside the operation panel controls the first telescopic rod to drive the side plate to move, so that the head of the sheep is located in the first restraint groove. When the pressure sensor inside the first restraint groove detects pressure, the second telescopic rod starts, and drives the movable limit plate to move through the second telescopic rod, so that the movable limit plate slides on the surface of the guide rod inside the moving groove. Furthermore, the second restraint groove at the bottom of the movable limit plate and the first restraint groove at the top of the side plate restrain the head of the sheep. When the head of the sheep moves, the movable limit plate can move upward, thereby squeezing the movable spring, so that the movable limit plate can move, avoiding damage to the sheep caused by the movable limit plate. After the sheep finishes moving, the movable limit plate will continue to restrain the head of the sheep under the reaction force of the movable spring, avoiding stress on the sheep caused by too tight restraint.

[0022] (2) In this solution, the infrared sensors on the sides of the first mounting block and the second mounting block detect the position of the sheep's legs. When the sheep's legs are detected, the PLC controller controls the fourth telescopic rod and the fifth telescopic rod to adjust the positions of the first mounting block and the second mounting block respectively, so that the mounting bins on the sides of the first mounting block and the second mounting block correspond to the front legs and hind legs of the sheep respectively. At this time, the third telescopic rod is started, so that the third telescopic rod drives the sliding block to slide on the surface of the sliding rod. When the pressure sensor on the surface of the mounting bin detects pressure, the motor is started to drive the first gear disk to rotate. The rotation of the first gear disk will drive the second gear disk to rotate. The rotation of the second gear disk drives the connecting rod to rotate. The rotation of the connecting rod will drive the first connecting plate to rotate. Since the first connecting plate is fixedly connected to the first movable clamping plate, the first movable clamping plate and the second connecting plate will rotate under the action of the rotating rod and the motor, so that the first movable clamping plate and the second movable clamping plate fix the limbs of the sheep.

[0023] (3) Since tensile springs are provided on both sides of the first fixed clamping plate and the second fixed clamping plate close to the mounting bin, and tensile springs are also provided on both sides of the first movable clamping plate and the second movable clamping plate close to the other mounting, the first fixed clamping plate, the second fixed clamping plate, the first movable clamping plate and the second movable clamping plate can adapt to the size of the sheep's limbs, improving the flexibility of the device.

[0024] (4) The position of the sheep is located by an infrared sensor, and the PLC controller automatically adjusts the head restraint mechanism. The head restraint is driven by the side plate driven by the first telescopic rod, and the pressure sensor triggers the movable limit plate, which cooperates with the spring buffer to avoid damage; the limbs are fixed by adjusting the position of the mounting block through the fourth telescopic rod and the fifth telescopic rod, and the third telescopic rod drives the sliding block. The pressure triggers the motor to drive the gear transmission, so that the adaptive splint containing the tension spring fixes the limbs, thereby realizing automatic adjustment and flexible restraint, taking into account safety and body adaptability, improving the efficiency of shearing operations, and can be adaptively adjusted according to the body shape of the sheep, without the need for manual adjustment for each sheep, thereby improving the practicality of the device.

At this time, start the third telescopic rod 43, so that the third telescopic rod 43 drives the sliding block 41 to slide on the surface of the slide rod 42. When the pressure sensor on the surface of the mounting bin 481 detects pressure, start the motor 485 to drive the first gear disk 486 to rotate. The rotation of the first gear disk 486 will drive the second gear disk 487 to rotate. The rotation of the second gear disk 487 drives the connecting rod 488 to rotate. The rotation of the connecting rod 488 will drive the first connecting plate 489 to rotate. Since the first connecting plate 489 is fixedly connected to the first movable clamping plate 4812, the first movable clamping plate 4812 and the second connecting plate 4810 will rotate under the action of the rotating rod 4811 and the motor 485, so that the first movable clamping plate 4812 and the second movable clamping plate 4813 fix the limbs of the sheep, and then the shearing work of the sheep can be carried out.
