Description

Technical Field

[0001] The present disclosure relates to the technical field of poultry injection auxiliary equipment, and particularly relates to a skin-grabbing and lifting mechanism for poultry chicks. Background Art

[0002] After hatching, poultry chicks usually need to be vaccinated. In today's society, the breeding industry is becoming more and more centralized and large-scale; coupled with the continuous increase in labor costs; in this context, it has become a trend for machines to replace manual vaccination. At present, the chick injection machines in the market can be generally divided into two types: semi-automatic and fully automatic from the structure; semi-automatic injection depends on people to pick up the chicks, press the chicks into the front-end model of the injection machine needle and trigger the mechanism to insert the needle for injection; this type of injection machine has high requirements for people, is not easy to master, and the needle is easy to prick the hand. The fully automatic injection machine hangs the chicks in the machine mold, and then moves the chicks to the syringe for injection; the whole injection process does not require human participation, thus reducing human errors and improving the injection quality. However, for the fully automatic injection machines on the market at present, when injecting, the needle is directly pressed on the neck of the chick, and then the needle is inserted for injection; this causes the needle to easily penetrate into the chick's body or even bone, resulting in bleeding or death of the chick; problems such as the needle being inserted obliquely or not inserted in place resulting in missed injection also occur from time to time.

[0032] Embodiment

[0033] As Figures 1-7 shown, this embodiment provides a poultry chick skin-grabbing and lifting mechanism, which includes a housing 1, a grabbing assembly, and a pushing and pulling assembly 4. The housing 1 is provided with a movable cavity 101. The grabbing assembly includes a slider, which is slidably connected to the movable cavity 101. Two symmetrically arranged grabbing fingers 3 are hinged to the end of the slider. The pushing and pulling assembly 4 includes a pull rod 41. An expanding member 42 is provided on the upper part of the pull rod 41. The expanding member 42 is embedded between the two grabbing fingers 3. By the expanding member 42, the front ends of the grabbing fingers 3 are expanded, so that they are in an open state under normal conditions. A driving member 43 is fixedly connected to the lower part of the pull rod 41. The driving member 43 drives the pull rod 41 to move back and forth in the movable cavity 101. During the process of the pull rod 41 moving back and forth, the tail ends of the grabbing fingers 3 are squeezed by the expanding member 42, and the front ends of the grabbing fingers 3 rotate and close, so as to grab the skin of the poultry chick. Then, it continues to move backward, and the whole grabbing assembly moves backward to lift the grabbed skin, so as to facilitate the injection of vaccines.

[0034] Specifically, the housing 1 includes an upper shell plate 11 and a lower shell plate 12. The upper shell plate 11 and the lower shell plate 12 are fixedly connected by bolts. An activity cavity 101 is formed between the upper shell plate 11 and the lower shell plate 12. An opening allowing the push-pull assembly 4 to pass through is provided at the end of the lower shell plate 12.

[0035] Wherein, the slider includes an upper slide plate 21 and a lower slide plate 22. The upper slide plate 21 and the lower slide plate 22 are fixedly connected by screws. The lower slide plate 22 is movably installed in the activity cavity 101. The middle part of the grasping finger 3 is hinged to the front end of the upper slide plate 21 through a rotating shaft.

[0036] Further, spring installation grooves 221 are respectively provided on both sides of the end of the lower slide plate 22. Spring guide rods 222 are embedded in the spring installation grooves 221. A slider return spring 223 is sleeved on the spring guide rods 222. One end of the spring guide rods 222 abuts against the inner wall of the activity cavity 101. When the lower slide plate 22 is driven by the push-pull assembly 4 to move in the activity cavity 101, the slider return spring 223 is compressed by extrusion. After the push-pull assembly 4 releases the acting force on the lower slide plate 22, it is reset by the elastic force of the two slider return springs 223.

[0037] Furthermore, there are also two finger return springs 211. The two finger return springs 211 are respectively arranged between the two grasping fingers 3 and the upper slide plate 21. Both ends of the finger return spring 211 respectively abut against the grasping finger 3 and the upper slide plate 21. The pull rod 41 drives the spreader 42 to move. During the movement of the spreader 42, the tail end of the grasping finger 3 is extruded, so that the grasping finger 3 rotates around the middle part as the axis, and the front end closes to grasp the skin of the poultry chick. The pull rod 41 drives the spreader 42 to reset. At this time, the finger return spring 211 drives the grasping finger 3 to reset and return to the open state.

[0038] Specifically, the driving member 43 includes a cylinder push rod 431. One end of the cylinder push rod 431 is fixedly connected to the lower part of the pull rod 41 by screws. The other end of the cylinder push rod 431 is fixedly connected with a cylinder piston 432. A cylinder cavity 434 allowing the cylinder push rod 431 to pass through is provided on the lower shell plate 12. The cylinder push rod 431 is embedded in the cylinder cavity 434. The cylinder piston 432 abuts against the inner wall of the cylinder cavity 434. One end of the lower shell plate 12 close to the cylinder piston 432 is fixedly connected with an end cover plate 433. A cylinder joint 435 is arranged on the side surface of the end cover plate 433. The cylinder joint 435 is connected to the cylinder cavity 434 in a penetrating manner. By connecting an air pipe through the cylinder joint 435 for ventilation, the cylinder push rod 431 is pushed to move in the cylinder cavity 434. The front and back movement of the cylinder push rod 431 drives the pull rod 41 to move back and forth, thereby driving the spreader 42 to move back and forth.

[0039] Further, a cylinder return spring 436 is sleeved on the cylinder push rod 431, and two ends of the cylinder return spring 436 respectively abut against the cylinder piston 432 and the inner wall of the cylinder cavity 434. After the air pipe connected to the cylinder joint 435 deflates, the cylinder push rod 431 is pushed to reset by the cylinder return spring 436.

[0040] Furthermore, inverted hanging plates 411 are fixedly connected to both sides of one end of the pull rod 41 close to the expanding member 42. During the movement of the pull rod 41, first, the expanding member 42 is driven to push the grasping fingers 3 to close. At this time, the whole grasping assembly is not driven to move. During the continuous movement of the pull rod 41, the inverted hanging plate 411 contacts the lower sliding plate 22, and the inverted hanging plate 411 pushes the lower sliding plate 22 to move. At this time, the whole grasping assembly moves backward, so as to lift the skin of the poultry chick.

[0041] In one embodiment, the expanding member 42 can be a bearing, a cylindrical structure or a slider structure, etc.

[0042] The working principle of the present utility model: As Figure 8 shown, in the initial state, the cylinder push rod 431 is in the retracted state under the action of the cylinder return spring 436 (the whole is embedded in the cylinder cavity 434), the lower sliding plate 22 is pushed to the opening of the movable cavity 101 under the action of the slider return spring 223, and the grasping fingers 3 are in the open state under the action of the finger return spring 211. The working process is divided into a grasping stage and a lifting stage. In the grasping stage, as Figure 9 shown, the cylinder joint 435 is connected to the air pipe to obtain air, which pushes the cylinder push rod 431 to move. The movement of the cylinder push rod 431 drives the pull rod 41 to move. The pull rod 41 drives the expanding member 42 to move. The expanding member 42 squeezes the grasping fingers 3 to make them close. As shown in this stage, since the elastic force of the slider return spring 223 is greater than the elastic force of the finger return spring 211, the grasping fingers 3 are pressed together and the whole grasping assembly does not move. In the lifting stage, the pull rod 41 continues to move backward. As Figure 10 shown, at this time, the inverted hanging plate 411 on the pull rod 41 hooks the lower sliding plate 22, and the lower sliding plate 22 is driven to move. As Figure 11 shown, thereby driving the whole grasping assembly to move backward to realize the lifting function.

[0043] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them; although the present disclosure has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present disclosure.
