Description

Technical Field

[0001] The invention relates to the field of livestock breeding, and in particular to an intelligent marking device for pig breeding. Background Art

[0002] Labeling is a unique mark that is specially applied to pigs to identify their identity during the pig farming process. This type of marking is one of the commonly used breeding management methods. It can help farmers track and manage the feeding of pigs and further improve the efficiency of pig breeding.

[0003] The development of laser technology has brought many conveniences to livestock farming. The laser marking machine can be used to mark the pig body with a QR code, so that farmers can easily track and manage the health status, vaccination records and other information of each pig. The existing Chinese public patent document: CN108812395B discloses a QR code laser marking machine for marking live pig information. The pig leg restriction rod and the pig abdomen restriction plate are extended under the live pig, and the pig leg restriction rod and the pig abdomen restriction plate are slid upward to contact the pig body, and the accompanying restriction block is passed through the movable accompanying slot, and the operating block is pulled, and the accompanying restriction block pops out, and the accompanying restriction block and the limit block move the pig leg on one side. The pig's leg limiting rod and the pig's abdomen limiting rod are stuck in the mobile accompanying groove and move toward the laser marking box at the same time, and the other end of the pig's leg limiting rod is placed in another mobile accompanying groove, so that the pig's four legs are restricted between the pig's leg limiting rod and the pig's abdomen limiting plate, and the pig cannot move, which is convenient for laser marking. Although the pig can be fixed, when the pig enters the corridor, due to the uncertainty of the pig's walking, when the two front limbs or two hind limbs of the pig cross, the leg limiting rod will squeeze the intersection of the two front limbs during the rising process, causing damage to the pig's legs. In addition, it is more difficult to mark when the pig is in pain, and the safety is low. Summary of the invention

A rack plate 27 matched with the gear 23 is fixedly installed on the outer side of the slide box 26, so that the rotating rod 21 can drive the rack plate 27 to move through the gear 23. A sliding cavity for the movement of the slide box 26 is opened on the outer side of the support plate 2. A pressure rod 28 extending to the outer side of the slide box 26 is slidably installed on the inner side of the slide box 26. A sliding roller frame 29 is fixedly installed between the two adjacent pressure rods 28 away from the side of the slide box 26, so that the pressure rod 28 pushes the sliding roller frame 29 to press and control the side of the pig. A spring 30 is fixedly installed between one end of the pressure rod 28 away from the sliding roller frame 29 and the inner side of the sliding cavity, which is convenient for the sliding roller frame 29 to elastically press the side of the pig. The outer side of the sliding roller frame 29 is made of rubber to prevent excessive pressure on the side of the pig.

The elasticity of the spring 30 is used to control the pig in an elastic clamping manner to prevent the pig from swinging randomly when it is lifted, and reduce excessive pressure on the side of the pig, thereby improving the marking accuracy of the laser marking head 5.

[0035] Working principle: First, the staff drives the pig to be marked to the left side of the two support plates 2, so that the pig walks from the ramp 36 between the two support plates 2. Under the obstruction of the protective sliding door 3, the pig can stay under the laser marking head 5. Due to the limited space between the two support plates 2, the pig cannot turn its head. Then, the staff starts the drive motor 17, and the drive motor 17 drives the two counter-rotating screws 14 to rotate synchronously through the synchronous belt 18, so that the counter-rotating screws 14 drive the corresponding two moving blocks 15 to approach each other along the outside of the support rod 16, and the moving block 15 drives the mounting block 12 to move, so that the mounting block 12 pushes the articulated seat 10 to move upward through the connecting rod 11, and the two articulated seats 10 drive the push roller 9 to move upward synchronously, so that the push roller 9 lifts the bottom of the elastic metal strip 7, and the elastic metal strip 7 is in an arched state to lift the pig's body, so that the pig's limbs are attached to the inclined surface of the elastic metal strip 7, and at the same time, the moving block 15 drives the slider 19 to move synchronously along the long groove on the support plate 2, so that the slider 19 drives the rack plate The rack plate 20 drives the rotating rod 21 to rotate through the gear 1 22, and the rotating rod 21 drives the gear 23 to rotate synchronously. The gear 23 drives the slide box 26 to move along the inner side of the slide frame 25 through the rack plate 27. The slide box 26 drives the pressure rod 28 to move synchronously, so that the two pressure rods 28 drive the sliding roller frame 29 to contact the side of the pig. At this time, the pressure rod 28 squeezes the spring 30 inside the slide box 26, and the elasticity of the spring 30 is used to make the two sliding roller frames 29 elastically clamp the side of the pig. , the pig body can be quickly controlled to prevent it from swinging randomly. Then, the staff starts the laser marking head 5 to mark the controlled pig body. Finally, the staff starts the driving motor 17 again to move the push roller 9 downward, and the winding drum 6 retracts the elastic metal strip 7 downward and contacts the bottom plate 8, and the two sliding roller frames 29 are away from the side of the pig. The marked pig can walk out from the right side of the two support plates 2, thereby achieving the effect of safe marking and improving the marking efficiency.

An adjusting screw 32 is rotatably mounted on the inner side of the mounting frame 31. A moving plate 33 matching the adjusting screw 32 is fixedly mounted on the side of the U-shaped box 24 away from the support plate 2. The moving plate 33 is slidably mounted on the outer side of the mounting frame 31. When the adjusting screw 32 is rotated, the U-shaped box 24 can be driven to move up and down along the outer side of the support plate 2 through the moving plate 33. A sliding hole is provided on the surface of the U-shaped box 24 for the limited sliding of the protrusion on the support plate 2. The size of the protrusion is larger than the outer diameter of the gear 23. A U-shaped frame 34 is fixedly mounted on the inner side of the U-shaped box 24. The two ends of the U-shaped frame 34 The end is rotatably installed on the outer side of the rotating rod 21, and the top and bottom of the gear 23 are respectively in contact with the top and bottom of the inner side of the U-shaped frame 34, so that the U-shaped frame 34 can push the gear 23 to move along the outer side of the rotating rod 21. Two symmetrically distributed positioning bars 35 are fixedly installed on the inner side of the gear 23, and a positioning groove for the positioning bar 35 to limit the sliding of the positioning bar 35 is provided on the outer side of the rotating rod 21, so that the rotating rod 21 can drive the gear 2 23 to rotate through the positioning bar 35, and it is convenient for the gear 2 23 to drive the positioning bar 35 to move along the positioning groove on the rotating rod 21. Two symmetrically distributed guide rods 39 are fixedly installed on the outer side of the support plate 2, and the U-shaped box 24 is slidably installed between the two guide rods 39 to improve the stability of the movement of the U-shaped box 24.

[0037] In this embodiment: the staff can rotate the adjusting screw 32 so that the adjusting screw 32 drives the movable plate 33 to move along the outer side of the mounting frame 31, and the movable plate 33 drives the U-shaped box 24 to move synchronously along the outer side of the guide rod 39.
