Description

Technical Field

[0001] This invention belongs to the field of egg transportation, specifically a conveying device for collecting eggs in laying hen farming. Background Technology

[0002] The core objective of egg-laying hen farming is to build an efficient and stable production system around high-quality eggs, thereby meeting the rigid demand of humans for animal protein and various essential nutrients. In this production system, the optimization of the egg collection process is particularly crucial. By applying egg collection conveyor devices, eggs can be accurately and efficiently transferred to pallets for collection using automation technology. This method not only effectively avoids the drawbacks of low efficiency and easy egg breakage caused by manual operation, but also significantly improves the smoothness and reliability of the overall production process, providing key technical support for egg quality assurance and production efficiency improvement.

[0003] A patent application with publication number CN217780091U discloses an egg packaging and collection device for easy laying hen farming. It includes a base component and further comprises: a feeding assembly mounted on the base component; a clamping mechanism mounted on the top side of the base component, the clamping mechanism including a suction cup and an air pump; and a transfer component mounted on the base component, the transfer component including a container box. The air pump draws air to create a negative pressure on the top side of the suction cup, achieving adsorption on the top of the egg. Subsequently, a pneumatic arc clamp precisely clamps the side of the egg. Through this clamping action, the clamping mechanism safely transfers the egg from the feeding assembly into the container box, completing the collection process.

[0004] In the above solution, the suction cup is designed based on an airtight adsorption and clamping mechanism. However, if there are stains, cracks, or moisture on the egg surface, the adsorption stability may be impaired or the clamping mechanism may fail. The arc clamp tightens the telescopic sleeve through air pressure. If the egg is irregularly shaped, the clamping force may be unevenly distributed, and local stress concentration may cause breakage, thereby increasing the risk of egg breakage. In addition, the air pump must continuously provide stable air pressure. If there is air pressure fluctuation or air leakage, the clamping force will be insufficient, which may cause the egg to fall off during transportation. This not only affects the current operation process, but the falling egg may also collide with other eggs to be transported, increasing the loss.

[0005] Therefore, the present invention provides a conveying device for collecting eggs in laying hen farming. Summary of the Invention

[0011] Preferably, the clamping mechanism further includes: a torsion spring installed between the first ring plate and the connecting rod; a sliding plate fixedly installed on the first ring plate, the sliding plate having a groove in the shape of an inverted right triangle; a movable plate for driving the ring plate to rotate, the movable plate having a protrusion that slides within the groove of the sliding plate, the movable plate driving the first ring plate to reciprocate through the sliding plate and the torsion spring; and a plurality of lead screws rotatably installed on the ring plate, the lead screws being used to drive the movable plate to move up and down reciprocally.

[0012] Preferably, the clamping mechanism further includes: a first bevel gear for driving the second ring plate to rotate, the first bevel gear being fixedly mounted on the second ring plate; a second bevel gear for driving the first bevel gear to rotate, the second bevel gear being rotatably mounted on the first ring plate; and a rack for driving the second bevel gear to rotate, the rack being fixedly mounted on the connecting rod.

[0013] Preferably, the support rod adopts a telescopic structure, and the support rod is rotatably installed below the feeding mechanism.

A cleaning box for sealing and cleaning the clamping mechanisms away from the discharge port is slidably installed below the feeding mechanism. A monitoring device is provided below the feeding mechanism to observe the condition of the eggs inside the clamping mechanisms, and to control the rotation of the support rod to replace the two sets of clamping mechanisms when the eggs are damaged.

[0014] Preferably, the clamping mechanism further includes: a connecting ring one and a connecting ring two installed between two adjacent lead screws, wherein the connecting ring one has an annular groove, the connecting ring two is inserted into the annular groove, and the opening angle of the annular groove on the connecting ring one between each lead screw is different.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. The present invention relates to an egg collection and conveying device for laying hen farming. By optimizing the clamping mechanism and replacing the original pneumatic system with a pure mechanical transmission method, it improves the problems of air pressure fluctuations or air leakage, insufficient clamping force, and eggs falling off during transportation. In addition, the telescopic sleeve elastically wraps the eggs throughout the process, eliminating the risk of hard collisions. The elastic tube diameter is compatible with eggs of different sizes. The telescopic sleeve expands gradually to achieve controllable release and avoids falling impact. At the same time, the clamping mechanism is located below the feeding mechanism, which effectively avoids the problem of other eggs being damaged when the clamping force is insufficient.

[0020] 2. The egg collection and conveying device for laying hen farming described in this invention forms a dynamic conveying channel by setting multiple gripper components, realizing the step-by-step and stable transportation of eggs, effectively reducing the probability of egg breakage. The gripping mechanism can be expanded according to the needs of the production line to be suitable for scenarios with large vertical drops, such as multi-layer chicken cages to ground packaging lines.

[0021] 3. The egg collection and conveying device for laying hen farming described in this invention, through the setting of a cleaning box and two clamping mechanisms, allows for the alternation of the positions of the two clamping mechanisms in cases of egg breakage or prolonged use of the clamping mechanisms. This ensures normal operation while also cleaning the clamping mechanisms to prevent egg liquid from contaminating them and causing contamination of subsequent eggs. In conjunction with a sealing block, the bottom of the telescopic sleeve is sealed to prevent egg liquid from flowing out from that point after an egg breaks. Attached Figure Description

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] like Figures 1-10 As shown in the figure, an egg collection and conveying device for laying hen farming according to an embodiment of the present invention includes: a body 1, a feeding mechanism 2, a transfer mechanism 3, and a plurality of clamping mechanisms 4. The feeding mechanism 2 is fixedly installed on the body 1, and a plurality of discharge ports 5 are provided below it. A support rod 6 is provided below the feeding mechanism 2. The clamping mechanism 4 is installed on the support rod 6. The transfer mechanism 3 is rotatably installed on the body 1. The transfer mechanism 3 includes a tray 34. The clamping mechanism 4 is used to transfer eggs from the corresponding discharge ports 5 to the tray 34. The clamping mechanism 4 includes: an annular plate 41 installed on the support rod 6; a plurality of connecting rods 42 fixedly installed on the annular plate 41; a telescopic sleeve 43 installed inside the plurality of connecting rods 42; and a claw assembly 44 installed on the connecting rods 42. The claw assembly 44 includes a plurality of clamping plates 441 for expanding and shrinking the diameter of the telescopic sleeve 43.

[0036] Specifically, existing technology uses an air pump to extract air, thereby creating negative pressure on the top side of the suction cup to adsorb the top of the egg. Then, a pneumatic arc clamp is used to precisely hold the sides of the egg. The suction cup is designed based on an airtight adsorption and clamping mechanism. However, if there are stains, cracks, or moisture on the egg surface, it may impair the adsorption stability or cause the clamping mechanism to fail. The arc clamp is driven by air pressure to extend and tighten. If the egg is irregularly shaped, it may cause uneven distribution of clamping force, local stress concentration, and breakage, thereby increasing the risk of egg breakage. In addition, the air pump must continuously provide stable air pressure. If there are air pressure fluctuations or air leakage, the clamping force will be insufficient, which may cause the egg to fall off during handling. This not only affects the current operation process, but the falling egg may also collide with other eggs to be handled, increasing the loss.

[0037] The telescopic sleeve 43 can be made of a stretchable material such as rubber. Initially, the gripper assembly 44 is in a clamping state, located below the telescopic sleeve 43. Because the gripper assembly 44 is in a clamping state, the diameter of the telescopic sleeve 43 gradually decreases from top to bottom, forming a conical structure. During operation, eggs are placed on the feeding mechanism 2, causing them to be arranged in multiple rows and gradually transported towards the discharge port 5. When the eggs reach the discharge port 5, they fall into the telescopic sleeve 43 and are stretched... The upper flared section of the telescopic sleeve 43 supports the egg and prevents it from directly contacting the rigid clamp 441. Then, the transfer mechanism 3 is controlled to rotate to directly below the outlet of the telescopic sleeve 43, and the gripper assembly 44 is controlled to gradually release the gripper. Under the action of elastic restoring force, the telescopic sleeve 43 expands from top to bottom, and the increased diameter forms a slide. Under the action of gravity, the egg slowly slides down the inner wall of the expanded telescopic sleeve 43. The falling speed is buffered by the friction of the tube wall, and finally it falls smoothly onto the tray 34 of the transfer mechanism 3, completing the non-destructive collection.

[0038] By optimizing the clamping mechanism 4 and replacing the original pneumatic system with a pure mechanical transmission method, the above-mentioned problems have been improved. With the telescopic sleeve 43 elastically wrapping the egg throughout the process, the risk of hard collision is eliminated. The elastic tube diameter is compatible with eggs of different sizes. The telescopic sleeve 43 expands gradually to achieve controllable release and avoids falling impact. At the same time, the clamping mechanism 4 is located below the feeding mechanism 2, which effectively avoids the problem of other eggs being damaged when the clamping force is insufficient.

[0039] like Figure 4 , Figure 9 and Figure 10 As shown, the gripper assembly 44 contains several grippers and is evenly arranged along the length of the connecting rod 42, extending from the end of the connecting rod 42 to the tail, forming a multi-level gripping structure.

[0040] Specifically, when the egg enters the area of ​​the first-stage gripper assembly 44, the gripper assembly 44 remains in a loosened state, while the adjacent second-stage gripper assembly 44 maintains its grip, forming a transitional receiving platform. When the egg is fully inserted between the two-stage gripper assemblies 44, the first-stage gripper assembly 44 immediately closes and locks, controlling the second-stage gripper assembly 44 to begin loosening its grip. The egg slides downwards under gravity, and the third-stage gripper assembly 44 simultaneously prepares to receive it. After the transfer is complete, the second-stage gripper assembly 44 closes again, and this cycle repeats, forming a dynamic conveying channel to achieve a smooth, stepped transport of the egg. Figure 9 As shown, this effectively reduces the probability of egg breakage. The clamping mechanism 4 can be expanded according to production line needs, such as... Figure 10 As shown, it is suitable for scenarios with large vertical drops, such as multi-layer chicken coops to ground packaging lines.

[0041] like Figures 4-7As shown, the gripper assembly 44 includes: two annular plates 442 rotatably mounted on the connecting rod 42; annular plates 443 rotatably mounted on the first annular plate 442; one end of the clamping plate 441 rotatably mounted on the first annular plate 442; a connecting post 444 fixedly mounted between the two annular plates 443; and the clamping plate 441 and the connecting post 444 are slidably connected.

[0042] Specifically, during operation, by controlling the rotational movement of ring plate 443 relative to ring plate 442, the connecting column 444 is driven to make a circular motion, thereby driving the clamping plate 441 to rotate around its fixed end, realizing the clamping and releasing action. At the same time, controlling the rotation of ring plate 442 relative to ring plate 443 counteracts the torque generated by the movement of clamping plate 441, ensuring that the telescopic sleeve 43 does not twist.

[0043] like Figure 7 As shown, a bent plate 445 is rotatably installed on the end of the clamping plate 441 near the telescopic sleeve 43, and a connecting rope 7 is fixedly installed on the outside of the telescopic sleeve 43. The connecting rope 7 passes between the bent plate 445 and the clamping plate 441.

[0044] Specifically, since the telescopic sleeve 43 is prone to dirt and aging after long-term use, the connecting rope 7 of the telescopic sleeve 43 can be put on or removed from it by rotating the bending plate 445, so as to realize the disassembly and installation of the telescopic sleeve 43, which is more practical.

[0045] like Figure 1 and Figures 5-8 As shown, the clamping mechanism 4 further includes: a torsion spring 45 installed between the ring plate 442 and the connecting rod 42; a sliding plate 46 fixedly installed on the ring plate 442, the sliding plate 46 having a sliding groove 47, the sliding groove 47 being an inverted right-angled triangle shape; a movable plate 48 that drives the ring plate 41 to rotate, the movable plate 48 having a protrusion that slides within the sliding groove 47 of the sliding plate 46, the movable plate 48 driving the ring plate 442 to reciprocate through the sliding plate 46 and the torsion spring 45; and several lead screws 49 rotatably installed on the ring plate 41, the lead screws 49 being used to drive the movable plate 48 to move up and down reciprocally.

[0046] Specifically, the protrusion of the movable plate 48 is engaged in the slide groove 47. The lead screw 49 is a reciprocating lead screw 49. During operation, the lead screw 49 is controlled to rotate, driving the movable plate 48 to move up and down reciprocally. When the movable plate 48 moves upward, it drives the slide groove plate 46 and the ring plate 442 to rotate through the slide groove 47. At this time, the torsion spring 45 twists. When the movable plate 48 moves to the uppermost position, the slide groove plate 46 and the ring plate 442 return to their original positions under the action of the torsion spring 45. Then the movable plate 48 moves downward. At this time, the slide groove plate 46 and the ring plate 442 remain stationary. This cycle continues. The reciprocating rotation of the ring plate 442 drives the clamping plate 441 to open and close, realizing the expansion and contraction of the telescopic sleeve in the pipe diameter.

[0047] like Figure 1 , Figure 5 and Figure 7 As shown, the clamping mechanism 4 further includes: a bevel gear 410 for driving the second ring plate 443 to rotate, the bevel gear 410 being fixedly mounted on the second ring plate 443; a bevel gear 411 for driving the first bevel gear 410 to rotate, the bevel gear 411 being rotatably mounted on the first ring plate 442; and a rack plate 412 for driving the second bevel gear 411 to rotate, the rack plate 412 being fixedly mounted on the connecting rod 42.

[0048] Specifically, as the first ring plate 442 rotates, it drives the second ring plate 443 and the second bevel gear 411 to rotate. Since the second bevel gear 411 meshes with the rack plate 412, the second bevel gear 411 rotates while rotating. The rotation of the second bevel gear 411 drives the first bevel gear 410 to rotate, causing the second ring plate 443 to rotate relative to the first ring plate 442. The rotation of the second ring plate 443 causes the connecting column 444 to make a circular motion, thereby driving the clamping plate 441 to rotate around its end, realizing the clamping and releasing actions.

[0049] like Figure 1 and Figure 3 As shown, the support rod 6 adopts a telescopic structure. The support rod 6 is rotatably installed below the feeding mechanism 2. Its end symmetrically contains two sets of clamping mechanisms 4. A cleaning box 8 for sealing and cleaning the clamping mechanisms 4 away from the discharge port 5 is slidably installed below the feeding mechanism 2. A monitoring device is set below the feeding mechanism 2 to observe the condition of the eggs inside the clamping mechanisms 4. When the eggs are damaged, the support rod 6 is controlled to rotate to replace the two sets of clamping mechanisms 4.

[0050] Specifically, the monitoring equipment uses existing industrial production line equipment. The telescopic sleeve 43, the annular plate 41, and the clamping mechanism 4 are all made of transparent material. The cleaning box 8 is connected to the water and air system. The bottom of the cleaning box 8 contains a crushing mechanism that can crush eggshells and egg liquid. Figure 3In the process, the clamping mechanism 4 located above the tray 34 is the working position. After the monitoring equipment captures a broken egg inside the telescopic sleeve 43, if the lowest clamping claw assembly 44 remains closed, the control screw 49 does not rotate, and the clamping claw assembly 44 remains stationary. If the lowest clamping claw assembly 44 is open, the control screw 49 quickly rotates in the opposite direction to clamp the lower clamping claw assembly 44, preventing egg liquid or more egg liquid from leaking out. Then, the cleaning box 8 is opened and slid backward, allowing the clamping mechanism 4 inside to be exposed. Then, the support rod 6 is rotated and controlled to retract, changing the position of the two clamping mechanisms 4. After the change is completed, the support rod 6 is extended, and the cleaning box 8 is slid to take the clamping mechanism 4 inside. Then, the cleaning box 8 is closed, and the connected water and air system is controlled to clean the clamping mechanism 4, ensuring normal operation while cleaning the clamping mechanism to prevent egg liquid from contaminating the clamping mechanism 4 and causing contamination of subsequent eggs.

[0051] like Figure 8 As shown, the clamping mechanism 4 also includes a connecting ring 413 and a connecting ring 414 installed between two adjacent lead screws 49. The connecting ring 413 has an annular groove 415, and the connecting ring 414 is inserted into the annular groove 415. The opening angle of the annular groove 415 on the connecting ring 413 between each lead screw 49 is different. The opening angle is determined by the angle between the radius lines of the two side boundaries of the groove and is arranged in an arithmetic gradient along the axial direction.

[0052] Specifically, after the cleaning box 8 closes, the control screw 49 continues to rotate, causing the lower gripper assembly 44 to move to the critical state of being fully open. At this point, the broken egg falls to the bottom of the cleaning box 8 due to the loss of effective gripping. Then, the control screw 49 rotates in the opposite direction, causing the connecting ring 414 to contact the other side of the annular groove 415. When the connecting ring 414 disengages from one side of the annular groove 415 and moves to the other side, the upper screw 49 remains briefly still due to the interruption of torque transmission. After the connecting ring 414 and the opposite side of the annular groove 415 complete contact, the rotational phase difference between the two screws 49 is eliminated, achieving synchronous transmission. The opening and closing degrees between the two gripper assemblies 44 are consistent. The control screw 49 continues to rotate, causing the opening and closing degrees of all gripper assemblies 44 to gradually become consistent. Then, the screw 49 continues to rotate, reaching the critical state of being fully open, forcing the telescopic sleeve 43 to fully expand and form a smooth channel, providing an unobstructed working space for subsequent high-pressure water and air cleaning.

[0053] like Figure 7 As shown, a sealing block 9 is slidably mounted on the clamping plate 441 of the gripper assembly 44 located at the tail of the connecting rod 42, and a spring 10 is installed between the sealing block 9 and the clamping plate 441.

[0054] Specifically, when in the clamping state, if each sealing block 9 and clamping plate 441 forms a circle to clamp the telescopic sleeve 43, so as to ensure that the egg liquid cannot flow out from there, the spring 10 is in the stretched state. After the claw is released, the spring 10 drives the sealing block 9 to slide through the elastic force, so that the sealing block 9 contacts the end of the adjacent clamping plate 441, avoiding the part of the telescopic sleeve 43 from intervening between the sealing block 9 and the adjacent clamping plate 441.

[0055] like Figure 1 and Figure 2 As shown, the feeding mechanism 2 includes a housing 21 fixedly installed on the machine body 1. Several rotating shafts 22 are rotatably installed inside the housing 21. The rotating shafts 22 are provided with spiral blades 23 for driving the eggs to move.

[0056] Specifically, the egg is placed between two adjacent rotating shafts 22, and the rotating shafts 22 are controlled to rotate, which drives the spiral blades 23 to rotate synchronously, pushing the egg to move closer to the discharge port 5.

[0057] like Figure 1 and Figure 3 As shown, the transfer mechanism 3 includes a telescopic rod 31 rotatably mounted on the body 1, a connecting block 32 is installed at the end of the telescopic rod 31, and a plurality of support plates 33 are mounted in a circular array on the connecting block 32, and a pallet 34 is detachably mounted on the support plate 33.

[0058] Specifically, after the tray 34 at the work station is filled with eggs, the telescopic rod 31 is controlled to retract and rotate so that the tray 34 leaves the work station and the next tray 34 moves into the work station. Then the telescopic rod 31 is controlled to extend so that the tray 34 is located below the clamping mechanism 4 to collect the eggs transferred down from the clamping mechanism 4.

[0059] Working principle: During operation, eggs are placed on the feeding mechanism 2, causing them to be arranged in multiple rows and gradually transported towards the discharge port 5. When the eggs reach the discharge port 5, they enter the area of ​​the first-end gripper assembly 44. At this point, the gripper assembly 44 remains in a loose state, while the adjacent second-stage gripper assembly 44 maintains clamping, forming an inverted conical receiving platform. The eggs fall into the telescopic sleeve 43 and are supported by it, avoiding direct contact with the rigid clamping plate 441. The second-stage gripper assembly 44 is then controlled to loosen its grip, and the telescopic sleeve 43 gradually expands from top to bottom under the action of elastic restoring force, increasing the diameter to form a slide. Under the action of gravity, the eggs slowly slide down the inner wall of the expanding telescopic sleeve 43. After the transfer is completed, the second-stage gripper assembly 44 closes again. This cycle is repeated to form a dynamic conveying channel, realizing the step-like and stable transportation of eggs until they fall smoothly onto the tray 34 of the transfer mechanism 3, completing the non-destructive collection.

[0060] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
