Abstract

This invention relates to an egg-collecting device in a planar two-way synchronous transfer system for grading poultry eggs. It includes two rows of egg-collecting mechanisms, each with its own egg-carrying space located within an egg-collecting frame assembly. Each row forms an openable and closable egg-carrying space with the frame assembly, and is tensioned laterally by elastic tensioning parts. In its free state, the egg-carrying space is closed, allowing eggs to enter. When an egg is released, the upper part of the egg-carrying space gradually closes, the elastic tensioning parts are stretched, and the lower part of the space gradually opens to release the egg. This invention features a compact structure and a small center distance, matching the spacing between the two rows of egg-collecting mechanisms on both fast and slow conveyor lines. The egg-collecting frame assembly has a frame-like structure, ensuring structural stability during operation and reducing the risk of egg breakage. The opening of the egg-carrying space is driven by external force to the egg-collecting frame assembly, while closure is achieved by the elastic tensioning parts, satisfying the opening and closing control of both rows of egg-collecting mechanisms.

Description

Technical Field

[0001] This invention relates to the field of poultry egg primary processing technology, and more specifically to an egg receiving device for a planar two-way synchronous transfer system for poultry egg grading. Background Technology

[0002] my country started relatively late in the field of poultry egg primary processing equipment manufacturing, but with the development in recent years, China has also made some achievements in this field. For example, patent document CN111846352A discloses a new type of transitional conveying device for poultry egg grading and packaging. This technology was used to mass-produce an integrated poultry egg grading and packaging machine in the same year. The main technical goal of this equipment is to transfer eggs from a slow six-channel conveyor to a single-row fast conveyor line.

[0003] In recent years, the scale of egg-laying hen farming in China has continued to expand, and the scale and intensification of egg-laying hen farming have been continuously improving. Equipment with a capacity of 30,000 eggs per hour can no longer meet the demand.

[0004] To further increase the equipment capacity from 30,000 eggs / hour, the current mainstream international solutions involve increasing the number of rows in the high-speed conveyor line. A single row of high-speed lines can reach 30,000 eggs / hour, two rows can reach 60,000 eggs / hour, and four rows can reach 120,000 eggs / hour. Simultaneously, this can be achieved by increasing the number of rows in the slow-speed feed section or increasing the operating speed of the slow-speed feed. For example, in existing technologies, the eggs are grouped into sets of three, and a lifting arm is used to lift each group of eggs in a staggered order and feed them into multiple rows of high-speed conveyors.

[0005] However, existing technologies, such as the single-row egg conveying device disclosed in patent document CN111846352A, have the following drawbacks:

[0006] 1. The structure is not compact enough. If the single-row egg conveyor device mentioned above is increased to two rows, such as... Figure 11 As shown: The center distance L between the two rows in the figure is too large, which cannot match the egg receiving distance of the double rows of the fast conveyor line, nor can it match the distance of the slow conveyor line.

[0007] 2. The two rows of spliced ​​structures are cantilever beam structures. During operation, the entire egg-catching device will shake, become unstable, and increase the risk of egg breakage.

[0008] 3. The opening and closing mechanism of the single-row egg conveyor relies on a fixed guide rail, which cannot control the opening and closing of two rows.

[0009] Therefore, how to provide an egg-receiving device for a planar two-way synchronous transfer system for grading poultry eggs, and overcome the above-mentioned technical problems, is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0010] Therefore, the purpose of this invention is to provide an egg-receiving device for a planar two-way synchronous transfer system for grading poultry eggs, overcoming the problems pointed out in the background art.

[0011] This invention provides an egg-collecting device for a planar two-way synchronous transfer system for grading poultry eggs, comprising two rows of egg-collecting mechanisms. Each row of egg-collecting mechanisms includes a left egg-collecting component and a right egg-collecting component, which are interlocked to form multiple egg-carrying spaces in a single row. The egg-carrying spaces of each row of egg-collecting mechanisms are located within an egg-collecting frame assembly and together with the egg-collecting frame assembly form an openable and closable egg-carrying space. Each space is tightened in the left and right directions by an elastic tensioning part, so that the egg-carrying space is closed in the free state when the poultry egg enters. When the poultry egg is released, the upper part of the egg-carrying space gradually closes, the elastic tensioning part is tightened and extended, and the lower part of the egg-carrying space gradually opens to release the poultry egg.

[0012] Furthermore, the left egg receiving assembly and the right egg receiving assembly are arranged symmetrically in the left-right direction.

[0013] Furthermore, both the left egg receiving assembly and the right egg receiving assembly include:

[0014] A support rod, which is connected to the egg-catching frame assembly;

[0015] Egg catcher: Multiple egg catchers with inward openings are arranged sequentially on the support rod, and two opposing egg catchers constitute the egg-carrying space.

[0016] The control unit is installed at both ends of the support rod. The control unit of the left egg receiving assembly and the control unit of the right egg receiving assembly can rotate relative to each other after being closed.

[0017] Furthermore, the control unit of the left egg receiving assembly is a left rotating gear, and the control unit of the right egg receiving assembly is a right rotating gear that meshes with and rotates with the left rotating gear.

[0018] Furthermore, the support rod includes an upper rod and a lower rod arranged vertically, wherein the length of the lower right rod in the right egg receiving assembly is greater than the length of the lower left rod in the left egg receiving assembly; the two ends of the elastic tensioning part are respectively connected to the lower left rod and the lower right rod.

[0019] Furthermore, both ends of the support rod have limiting and fixing blocks.

[0020] Furthermore, the egg-catching frame component includes:

[0021] Connecting rods, wherein the connecting rods are two parallel cylindrical rods;

[0022] The left and right frames are connected to mirror-arranged left and right frames at both ends of each connecting rod, and the left and right frames are connected to the support rod.

[0023] Furthermore, both the left frame and the right frame include, from the inside out: an inner adjusting opening and closing rod, a synchronous sliding block, and an outer adjusting opening and closing rod; the two connecting rods, the synchronous sliding block corresponding to the left frame, and the synchronous sliding block corresponding to the right frame are connected to form a frame; wherein the upper part of the synchronous sliding block is provided with an upper rod connecting hole for installing the upper rod, and the inner adjusting opening and closing rod and the outer adjusting opening and closing rod can slide relative to the synchronous sliding block.

[0024] Furthermore, one end of the inner adjusting opening and closing rod is the inner driving end, and the side of the outer adjusting opening and closing rod away from the inner driving end of the inner adjusting opening and closing rod is the outer driving end; the inner adjusting opening and closing rod slides to drive the lower left rod to move, and the outer adjusting opening and closing rod slides to drive the lower right rod to move.

[0025] Furthermore, the inner adjusting opening and closing rod has an inner vertical strip hole, an inner horizontal strip hole, and a rectangular hole; the outer adjusting opening and closing rod has an outer vertical hole corresponding to the inner vertical strip hole and an outer horizontal strip hole corresponding to the inner horizontal strip hole; the lower part of the synchronous sliding block has a supporting circular hole corresponding to the inner horizontal strip hole and the outer horizontal strip hole;

[0026] The inner horizontal bar hole, the supporting circular hole, and the outer horizontal bar hole are connected by an adjusting opening and closing rod pin.

[0027] The lower left rod is inserted into the inner vertical strip hole;

[0028] The lower right rod is inserted into the rectangular hole and the outer vertical hole;

[0029] The sliding of the inner adjusting lever does not affect the lower right lever; the sliding of the outer adjusting lever does not affect the lower left lever.

[0030] As can be seen from the above technical solution, compared with the prior art, the present invention has the following beneficial effects:

[0031] The two-row egg-collecting mechanism of this invention is connected within the same egg-collecting frame assembly, featuring a compact structure and small center-to-center distance, which can match the spacing of the double-row egg-collecting mechanism on both fast and slow conveyor lines. The egg-collecting frame assembly has a frame-shaped structure, ensuring structural stability during operation and reducing the risk of egg breakage. The opening of the egg-carrying space is achieved by external force driving the egg-collecting frame assembly, while closure is achieved by an elastic tensioning part, satisfying the opening and closing control of the two-row egg-collecting mechanism.

[0043] Figure 11 This is a schematic diagram of increasing the number of rows of egg conveyors in the existing single-row technology to two rows. Detailed Implementation

[0044] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0045] To further increase the production capacity of existing equipment beyond 30,000 pieces / hour, the mainstream solution is to increase the number of rows of the high-speed conveyor line. A single row of high-speed lines can achieve 30,000 pieces / hour, two rows can achieve 60,000 pieces / hour, and four rows can achieve 120,000 pieces / hour. Simultaneously, this can be achieved by increasing the number of rows of slow-speed feeders or increasing the operating speed of the slow-speed feeders. See appendix. Figure 11 By adding a second row to the existing single-row egg conveyor, a two-row egg conveyor was created. However, the center distance of the combined structure is large, making it unsuitable for matching the spacing of the double-row egg-receiving lines in high-speed conveyor lines or in slow-speed conveyor lines. Furthermore, the combined structure is a cantilever beam structure, causing the entire egg-receiving device to vibrate and become unstable during operation, increasing the risk of egg breakage. The single-row egg conveyor's opening and closing mechanism relies on fixed guide rails, making it impossible to control the opening and closing of both rows.

[0046] In view of this, the present invention provides an egg-receiving device for a planar two-way synchronous transfer system for grading poultry eggs, comprising two rows of egg-receiving mechanisms, see attached figure. Figure 1-10 Each row of egg-catching mechanisms includes a left egg-catching component 10 and a right egg-catching component 20. The left egg-catching component 10 and the right egg-catching component 20 are interlocked to form multiple egg-carrying spaces in a single row. The egg-carrying spaces of each row of egg-catching mechanisms are located within the egg-catching frame component 30 and form an openable and closable egg-carrying space with the egg-catching frame component 30. They are all tightened in the left and right directions by the elastic tensioning part 40, so that the egg-carrying space is closed in the free state. When the egg enters in this state, when the egg is released, the upper part of the egg-carrying space gradually closes, the elastic tensioning part 40 is tightened and extended, and the lower part of the egg-carrying space gradually opens to release the egg.

[0047] Therefore, the above solution connects the two rows of egg-collecting mechanisms within the same egg-collecting frame assembly, resulting in a compact structure with a small center distance, matching the spacing between the double rows of egg-collecting mechanisms on both fast and slow conveyor lines. The egg-collecting frame assembly has a frame-like structure, ensuring structural stability during operation and reducing the risk of egg breakage. The opening of the egg-carrying space is driven by external force to open the egg-collecting frame assembly, while closing relies on an elastic tensioning part, satisfying the opening and closing control of the two rows of egg-collecting mechanisms.

[0048] Advantageously, the left egg receiving assembly 10 and the right egg receiving assembly 20 are arranged symmetrically in the left-right direction.

[0049] It is worth noting that, in the description of this invention, the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0050] See appendix Figure 2-4 Both the left egg-catching assembly 10 and the right egg-catching assembly 20 include:

[0051] A support rod, which is connected to the egg-catching frame assembly 30;

[0052] Egg catcher 16: Multiple egg catchers 16 with inward openings are arranged sequentially on the support rod, and two opposing egg catchers 16 constitute the egg-carrying space.

[0053] The control unit is installed at both ends of the support rod. The control unit of the left egg receiving assembly 10 and the control unit of the right egg receiving assembly 20 can rotate relative to each other after they are closed.

[0054] The control unit of the left egg-receiving assembly 10 is a left-hand rotating gear 13, and the control unit of the right egg-receiving assembly 20 is a right-hand rotating gear 21 that meshes with the left-hand rotating gear 13. This achieves stable opening and closing of the egg-carrying space.

[0055] In other embodiments, the control unit only needs to be able to achieve positioning and mutual rotation to ensure the stable opening and closing of the egg-carrying space, such as a pair of cooperating arc blocks, one arc block having at least a portion of concavity and the other arc block having at least a portion of convexity.

[0056] Advantageously, the left-hand rotating gear 13 and the right-hand rotating gear 21 have incomplete tooth structures. Generally speaking, the toothed parts on the top mesh with each other, while the toothless parts on the bottom support each other. Their inclination direction is consistent with the opening surface of the egg catcher 16. That is, since the egg-carrying space is initially a conical structure that is larger at the top and smaller at the bottom, in the initial state, the toothless parts on the bottom of the left-hand rotating gear 13 and the right-hand rotating gear 21 support each other. In this state, the egg-carrying space is closed. When the egg enters and is released, the lower part of the egg-carrying space gradually opens, and the upper teeth of the left-hand rotating gear 13 and the right-hand rotating gear 21 engage.

[0057] The support rod includes an upper rod 11 and a lower rod arranged vertically, wherein the length of the lower right rod 22 in the right egg receiving assembly 20 is greater than the length of the lower left rod 12 in the left egg receiving assembly 10; the two ends of the elastic tensioning part 40 are respectively connected to the lower left rod 12 and the lower right rod 22.

[0058] In this invention, the elastic tensioning part 40 can be a spring or an elastic element with the same function of automatic return after tensioning, such as an elastic band.

[0059] Preferably, the egg catcher 16 is mounted on the egg catcher fixing seat 17.

[0060] In the above embodiment, both ends of the support rod have limiting and fixing blocks 14 for limiting.

[0061] In the left egg-catching assembly, the upper rod 11 and the lower left rod 12 pass through two holes on the limiting fixing block 14, and the three parts are fixed together using the locking nut 15. Similarly, the left rotating gear 13 and the egg-catching gripper fixing seat 17 are fixed to the upper rod 11 and the lower left rod 12 using the same method. The egg-catching gripper 16 is fixed to the egg-catching gripper fixing seat 17 with screws. Figure 2 There are multiple egg catchers 16 and egg catcher fixing bases 17. Only one is shown in the schematic diagram, and the others are hidden to observe their structure.

[0062] The right egg receiving assembly is basically the same as the left egg receiving assembly in terms of internal structure and installation. The difference is that the length of the lower right rod 22 in the right egg receiving assembly 20 is greater than the length of the lower left rod 12 in the left egg receiving assembly 10.

[0063] In an embodiment of the present invention, referring to 5-7, the egg-catching frame assembly 30 includes: a connecting rod 32, which is two parallel cylindrical rods; a left frame and a right frame, each of the connecting rods 32 having a mirror-arranged left frame and a right frame at both ends, the left frame and the right frame being connected to the support rod.

[0064] Specifically, both the left frame and the right frame include, from the inside out: an inner adjusting opening and closing rod 31, a synchronous sliding block 33, and an outer adjusting opening and closing rod 34; the two connecting rods 32, the synchronous sliding block 33 corresponding to the left frame, and the synchronous sliding block 33 corresponding to the right frame are connected to form a frame; wherein the upper part of the synchronous sliding block 33 is provided with an upper rod connecting hole 33A for installing the upper rod, and the inner adjusting opening and closing rod 31 and the outer adjusting opening and closing rod 34 can slide relative to the synchronous sliding block 33.

[0065] Wherein, one end of the inner adjusting opening and closing rod 31 is the inner driving end, and the side of the outer adjusting opening and closing rod 34 away from the inner driving end of the inner adjusting opening and closing rod 31 is the outer driving end; the inner adjusting opening and closing rod 31 slides to drive the lower left rod 12 to move, and the outer adjusting opening and closing rod 34 slides to drive the lower right rod 22 to move.

[0066] In the above embodiments, the inner adjusting opening and closing rod 31 has an inner vertical strip hole 31A, an inner horizontal strip hole 31B, and a rectangular hole 31C; the outer adjusting opening and closing rod 34 has an outer vertical hole 34A corresponding to the inner vertical strip hole 31A and an outer horizontal strip hole 34B corresponding to the inner horizontal strip hole 31B; the lower part of the synchronous sliding block 33 has a supporting circular hole 33B corresponding to the inner horizontal strip hole 31B and the outer horizontal strip hole 34B;

[0067] The inner horizontal bar hole 31B, the supporting circular hole 33B, and the outer horizontal bar hole 34B are connected by an adjusting opening and closing rod pin 39 passing through them.

[0068] The lower left rod 12 is inserted into the inner vertical strip hole 31A;

[0069] The lower right rod 22 is inserted into the rectangular hole 31C and the outer vertical hole 34A;

[0070] The sliding of the inner adjusting rod 31 does not affect the lower right rod 22; the sliding of the outer adjusting rod 34 does not affect the lower left rod 12.

[0071] In this invention, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0072] Specifically, the egg-catching frame assembly 30 can be understood to include two connecting rods 32, two inner adjusting opening and closing rods 31, two outer adjusting opening and closing rods 34, and two synchronous sliding blocks 33. The left frame includes one inner adjusting opening and closing rod 31, one outer adjusting opening and closing rod 34, and one synchronous sliding block 33, which are connected by two adjusting opening and closing rod pins 39. The right frame is connected by one inner adjusting opening and closing rod 31 (i.e., the right inner adjusting opening and closing rod 35), one outer adjusting opening and closing rod 34 (i.e., the right outer adjusting opening and closing rod 36), and one synchronous sliding block 33, which are also connected by two adjusting opening and closing rod pins 39.

[0073] The connecting rod 32 has threaded holes at both ends, and bolts are used to connect the connecting rod 32 to the synchronous sliding block 33. The inner adjusting opening and closing rod 31 and the right inner adjusting opening and closing rod 35 are mirror images of each other, and the outer adjusting opening and closing rod 34 and the right outer adjusting opening and closing rod 36 are mirror images of each other. The sliding bearing 37 is connected to the inner adjusting opening and closing rod 31, the outer adjusting opening and closing rod 34, the right inner adjusting opening and closing rod 35, and the right outer adjusting opening and closing rod 36 respectively by bearing pins 38. Two adjusting rod pins 39 pass through the inner horizontal slot 31B, support hole 33B, and outer horizontal slot 34B of the inner adjusting rod 31, connecting the three parts together. Similarly, the other end is connected in the same way. Because the adjusting rod pins 39 pass through the inner horizontal slot 31B and outer horizontal slot 34B, the inner adjusting rod 31 and outer adjusting rod 34 can slide back and forth. The sliding range is limited by the inner horizontal slot 31B and outer horizontal slot 34B. The same applies to the other side.

[0074] Both ends of the upper rod 11 in the left egg receiving assembly 10 and the right egg receiving assembly 20 are inserted into the upper rod connecting holes 33A of the synchronous sliding block 33, respectively. The left rotating gear 13 in the left egg receiving assembly and the right rotating gear 21 in the right egg receiving assembly mesh with each other. The left and right ends of the elastic tensioning part 40 are connected to the lower left rod 12 in the left egg receiving assembly and the lower right rod 22 in the right egg receiving assembly, respectively. The lower left rod 12 is shorter than the lower right rod 22. After installation, one end of the lower left rod 12 will be inserted into the inner vertical bar hole 31A in the inner adjusting opening and closing rod 31, and the other end will be inserted into the same symmetrical position. The lower right rod 22 is relatively long. After installation, this part passes through the rectangular hole 31C in the inner adjusting rod 31 and then into the outer vertical hole 34A in the outer adjusting rod 34. This way, the inner adjusting rod 31 will not affect the lower right rod 22 during left and right sliding, because the lower right rod 22 passes through the rectangular hole 31C in the inner adjusting rod 31. Similarly, the outer adjusting rod 34 will not affect the lower left rod 12 during left and right sliding, because the lower left rod 12 is shorter and will not contact the outer adjusting rod 34. Thus, when the inner adjusting rod 31 slides left and right, it only controls the lower left rod 12, and when the outer adjusting rod 34 slides left and right, it only controls the lower right rod 22.

[0075] See appendix Figure 8-10 In the free state: the left egg receiving assembly 10 and the right egg receiving assembly 20 are in the closed state under the action of the tension spring, such as... Figure 8 In the first state diagram, the lower planes of the left rotating gear 13 and the right rotating gear 21 support each other to form a limit, waiting for the egg to enter the egg-collecting component. Once the egg enters, it is caught by the egg-collecting grabber 16. Figure 8As shown in the second state diagram, after the egg enters, it needs to be released. Simply move the two lower left levers 12 to the left and the two lower right levers 22 to the right. At this time, the spring is in the extended state, and the left and right egg-receiving components open, allowing the egg to leak out from below. Figure 8 The third state diagram is shown.

[0076] Figure 9 The outer adjusting rod 34 is connected to the synchronous sliding block 33 by the adjusting rod pin 39. When an external force (the arrow indicates the direction of the external force) pushes the sliding bearing 37 to the right, the outer adjusting rod 34 also moves to the right. At this time, the outer adjusting rod 34 will push the lower right rod 22 to the right. Similarly... Figure 10 When an external force (arrow direction indicates the direction of the external force) pushes the sliding bearing 37 to the left, the inner adjusting rod 31 also moves to the left. At this time, the inner adjusting rod 31 will push the lower left rod 12 to the left, thereby controlling the opening state of the egg receiving component.

[0077] It is worth noting that, theoretically, only one side needs to be controlled, because the left and right egg-catching components are connected by gears. In order to ensure that the egg-catching components are subjected to symmetrical forces, both sides are controlled simultaneously.
