Description

Technical Field

[0001] This utility model relates to the field of egg collection line technology, and in particular to a transmission chain structure for a central egg collection line. Background Technology

[0002] In modern, large-scale egg-laying hen farms, the central egg collection line is the core of the entire egg collection system. Its function is to automatically, centrally, and efficiently transport eggs produced from each level of the henhouse to designated sorting and packaging areas, thereby significantly reducing the labor intensity of manual collection, minimizing egg breakage, and improving production efficiency. The stability and reliability of the central egg collection line directly affect the farm's operational efficiency.

[0003] As the "artery" of the central egg collection line, its egg conveying structure is a key component for achieving the aforementioned functions. Currently, most common conveying structures employ chain drive, where a motor drives a transmission shaft, causing parallel chains on both sides to move slowly. Numerous support rods fixed to the chains form a series of intervals to support the eggs. After rolling out of the cage, the eggs fall into a stable space formed by two adjacent support rods and the bottom chain, and are then conveyed to the end by the movement of the chain.

[0004] However, the existing conveyor chain structure has some drawbacks: (1) Transmission slippage and asynchrony: Traditional drive methods (such as direct chain drive by sprockets) may slip between the chain and the drive component due to insufficient tension or wear during long-distance, light-load operation. This not only wastes energy, but more seriously, it may cause the chains on both sides to move asynchronously. Once asynchrony occurs, the support rods connecting the chains on both sides will tilt or twist, resulting in uneven spacing between the support rods, which can easily cause eggs to get stuck or squeeze each other, resulting in a high rate of egg breakage.

[0005] (2) High maintenance cost: The sprocket teeth and chain links are meshed transmissions. After long-term operation, both will wear out, requiring regular adjustment of the tensioning device or replacement of worn parts, which increases maintenance costs and downtime.

[0006] (3) Operational stability needs to be improved: The inherent characteristics of sprocket drive result in a certain degree of pulsation in the transmission, and there is an impact when starting and stopping, which is not conducive to the smooth transport of fragile items such as eggs.

[0007] Therefore, this utility model provides a central egg-collecting line transmission chain structure, which makes the transmission smoother. Utility Model Content

[0008] The purpose of this invention is to solve the problems existing in the prior art by proposing a central egg collection line conveyor chain structure.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: A conveyor chain structure for a central egg collection line includes a frame, with drive rollers rotatably mounted at both ends of the frame. The drive rollers are cloverleaf rollers. Each of the two sets of drive rollers has an annular chain link formed by several chain links sequentially assembled on opposite sides. Multiple egg-holding chains are spaced apart around the circumference between the two chain links, and the spacing between adjacent egg-holding chains satisfies the cloverleaf convex edge interlocking of the drive rollers.

[0010] Preferably, the inner wall of the frame is provided with a U-shaped groove, and an adjacent link of the chain is horizontally placed on the inner end face of the groove and vertically embedded in the groove, which is used to limit the stable transport of the chain link along the length direction of the frame.

[0011] Preferably, a wear-resistant strip is embedded in the inner side end face of the bracket.

[0012] Preferably, each link of the chain is welded and fixed with an egg-carrying chain.

[0013] Preferably, the egg-carrying chains on the vertical links of the chain are straight rods, and the egg-carrying chains on the horizontal links are arch-shaped, so that the horizontal portions of adjacent egg-carrying chains are level.

[0014] Preferably, a pressure strip is embedded in the outer side end face of the bracket.

[0015] Preferably, the transmission roller includes a rotating roller rotatably mounted on a frame, with two symmetrically fastened discs on the rotating roller, and a transmission bar detachably mounted on the two opposing convex edges of the two discs.

[0016] Preferably, the diameter of the transmission bar is larger than the size of the convex edge.

[0017] Compared with the prior art, this utility model provides a conveyor chain structure for a central egg collection line, which has the following beneficial effects: This invention uses a geared motor to drive a transmission roller, whose convex edge engages with the egg-carrying chain to propel the entire conveyor chain, thus achieving the transfer of eggs. Compared to traditional chain drives, the transmission structure in this design has a longer engagement point and a wider contact surface, resulting in more stable transmission and preventing slippage that could lead to asynchronous transmission. The wider contact surface also disperses the reaction force exerted on the transmission roller, reducing wear.

[0018] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[0033] The following will refer to the appendix in the embodiments of this utility model. Figure 1-13 The technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0034] Example 1: In order to solve the problems existing in the prior art, this example provides a conveyor chain structure for a central egg collection line.

[0035] See attached document Figure 1 Appendix Figure 4 As shown, the egg collection line consists of multiple segments: a horizontal first stage arranged between chicken houses; a second stage located outside the chicken houses and vertically distributed with the first stage; a third stage connecting with the second stage and having a downward slope; a fourth stage connecting with the third stage and having an arc-shaped change of direction; and a fifth stage located inside the egg storage and conveying eggs horizontally, connecting with the fourth stage. The segments are staggered at their joints to ensure a complete connection and prevent egg leakage. Inclined plates with a small inclination angle are also provided as a buffer for egg transfer, with baffles on both sides to prevent leakage. These five segments constitute a complete egg collection line system. While the structures of the five stages are largely similar, differing only in shape (e.g., horizontal or downward slope), this design focuses on a single horizontal stage for explanation.

[0036] This horizontal stage includes frame 1, which consists of C-shaped steel side plates on both sides. A crossbeam is installed between the two side plates along the length direction at intervals using bolts 206, thus forming a basic frame structure. Columns are installed on the side plates at intervals of several crossbeams using bolts 206. These columns support the frame, ensuring that the conveyor system meets height requirements.

[0037] Both ends of the two side plates are fastened with disc-shaped bearing seats by bolts 206. The inner rings of the bearings in both bearing seats jointly embed the drive roller 2, allowing the drive roller 2 to rotate on the frame 1. The drive roller 2 is a perforated roller, see attached diagram. Figure 11 As shown, the outer edge of the transmission roller 2 has multiple protruding edges, making the transmission roller 2 resemble a plum blossom when viewed from the side. The plum blossom protruding edges of the transmission roller 2 serve as the meshing transmission components. A geared motor is fastened to the frame 1 by bolts 206. The output end of the geared motor is connected to the shaft end of the transmission roller 2 through a coupling. The geared motor can drive the transmission roller 2 to rotate, providing power for the entire transmission chain structure.

[0038] Each of the two sets of drive rollers 2 has a chain link 3 on one of its opposite ends. The chain link 3 is a ring chain structure composed of several chain links pieced together in sequence. Multiple egg-holding chains 4 are spaced apart around the circumference between the two chain links 3 to form a conveyor chain, allowing the eggs to be held between the two sets of egg-holding chains 4 without falling off.

[0039] During installation, the two sets of chain links 3 are located at both ends of the drive roller 2 without contacting it. The conveyor belt is respectively fitted onto the two drive rollers 2, and the convex edges of the drive rollers 2 are respectively embedded between two adjacent egg-carrying chains 4 to form an interlocking transmission. The drive rollers 2 can be driven to rotate by a geared motor, and the entire conveyor chain is driven to transport eggs by the interlocking of the convex edges of the drive rollers 2 with the egg-carrying chains 4.

[0040] Compared to traditional chain drives, the transmission structure in this solution has a longer meshing transmission part and a wider contact surface, making the transmission more stable and preventing slippage that could lead to asynchronous transmission. The wider contact surface also makes the reaction force of the drive action on the transmission roller 2 more dispersed, which can reduce wear.

[0041] In this embodiment, each chain of the chain link 3 is welded and fixed with an egg-carrying chain 4 to meet the size requirements for holding the eggs. The egg-carrying chains 4 on the vertical links of the chain link 3 are straight rods, and the egg-carrying chains 4 on the horizontal links are arched, so that the horizontal parts of adjacent egg-carrying chains 4 are level, so that the eggs are stably held.

[0042] Example 2: To ensure smoother transmission of the drive chain, especially reducing the probability of axial slippage along the drive shaft during transmission, a U-shaped support groove 5 is provided on the inner wall of the frame 1, based on Example 1. (See attached diagram.) Figure 8 As shown, one of the adjacent links of the chain link 3 is horizontally placed on the inner end face of the tray 5 and the other is vertically embedded in the tray 5. The vertical connection is secured by the trays 5 on both sides, so that both ends of the conveyor chain are limited, thereby preventing the transmission chain from shifting left and right during transmission, and ensuring that the chain link 3 is stably conveyed along the length direction of the frame 1.

[0043] In this embodiment, a groove is provided on the end face of the inner side of the bracket 5, and a wear-resistant strip 6 with a T-shaped cross-section is embedded in the groove. The wear-resistant strip 6 serves as the base surface layer connected to the chain link 3 to withstand moving friction, and is easy to replace even if worn; compared to replacing the bracket 5, its replacement cost is also lower. The wear-resistant strip 6 can be divided into multiple sections and can be replaced individually.

[0044] In this embodiment, a pressure strip 7 is embedded in the outer side end face of the bracket 5. The pressure strip 7 abuts against the inner side of the vertical chain, thereby enhancing the limiting performance of the chain link 3 and reducing the probability of the chain link 3 slipping off.

[0045] In Example 3, the drive roller 2 is a scalloped roller with a raised edge on its surface that engages with the egg-carrying chain 4 to achieve power transmission. Even with the increased contact area, it is still prone to wear after prolonged use. Therefore, based on Example 1, the drive roller 2 is designed to be detachable, meaning the raised edge is detachably mounted to the drive roller 2 itself. See attached document Figure 10 Appendix Figure 12Appendix Figure 13 As shown, the transmission roller 2 includes a rotating roller 201 rotatably mounted on the frame 1. The end of the rotating shaft is a smooth shaft, while the inner side of the smooth shaft is a threaded shaft, the inner side of the threaded shaft is a rectangular shaft, and the inner side of the rectangular shaft is a retaining ring 204. The smooth shaft serves as a mating part with the bearing housing and is equipped with a keyway, connecting to the geared motor via a coupling. A plum blossom disc 202 is fitted onto the rectangular shaft; the inner hole of the plum blossom disc 202 is a rectangular hole adapted to the rectangular shaft, and the plum blossom disc 202 has the same planar shape as the plum blossom roller. A self-locking nut 203 is threadedly installed on the threaded shaft, abutting against the plum blossom disc 202 and cooperating with the retaining ring 204 to limit the position of the plum blossom disc 202. The retaining ring 204 is fixedly mounted on the rotating roller 201 by welding, or is designed integrally with the rotating roller 201. The above structure completes the basic design of the plum blossom disc 202.

[0046] The two opposing convex edges of the two plum blossom discs 202 are detachably fitted with a transmission bar 205. Each convex edge of the two plum blossom discs 202 has a threaded hole, and a bolt 206 is screwed into each threaded hole. The bolt 206 and the threaded hole have a self-locking engagement. The transmission bar 205 is a hollow tube, into which the shank end of the bolt 206 can be inserted. The transmission bar 205 is detachably mounted on the plum blossom discs 202 at both ends, thus forming the plum blossom roller structure in Embodiment 1.

[0047] With the above structure, the protruding edge designed along the length of the transmission roller 2 in Embodiment 1 is shortened and used only as an installation part. Then, the transmission bar 205 is used as a transmission component that engages with the egg-carrying chain 4 to realize power transmission. The transmission bar 205 is detachably engaged with the flower disc 202 by bolts 206. When the transmission bar 205 is worn or bent, it can be disassembled and replaced separately without the need for overall disassembly and replacement. This not only makes maintenance and replacement more convenient and faster, but also reduces scrap costs.

[0048] In this embodiment, the diameter of the transmission bar 205 is larger than the size of the convex edge. This ensures that the transmission bar 205 contacts the egg-carrying chain 4, while the convex edge of the plum blossom disc 202 does not. Thus, only the transmission bar 205 serves as the transmission contact element, preventing the plum blossom disc 202 from directly transmitting power by contacting the egg-carrying chain 4.

[0049] In this embodiment, the transmission bar 205 can also be plate-shaped, extending into the inside of the plum blossom disc 202. Each end is locked by two sets of bolts 206, which can prevent the transmission bar 205 from twisting and make the contact with the egg carrier chain 4 more stable.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
