Description

Technical Field

[0001] This utility model relates to the technical field of egg processing equipment, and in particular to an eggshell conveying device. Background Technology

[0002] In food processing and poultry farming, eggshell transportation is an indispensable part of the production process. As the outer protective structure of eggs, eggshells are fragile and have low strength, making them highly susceptible to breakage during transportation due to external impacts, drops, and other factors. Once an eggshell breaks, it not only leads to leakage of the egg liquid, wasting raw materials, but can also contaminate the transportation equipment and the surrounding environment, increasing subsequent cleanup costs and even affecting product quality and production efficiency. Therefore, the stability and safety of the eggshell transportation process are of paramount importance.

[0003] Currently, most eggshell conveying equipment used in the industry employs traditional horizontal or inclined conveyor belt structures. However, traditional conveyor belts lack specific cushioning and guiding structures, making it easy for eggshells to fall vertically when they enter the conveyor belt from the feed inlet. The direct impact force between the eggshells and the conveyor belt or equipment housing is significant, often resulting in a high eggshell breakage rate, making it difficult to meet the demands of efficient and low-loss production. Furthermore, during the conveying process, eggshells may accumulate impurities such as egg liquid, dust, and feather fragments on their surface. These impurities gradually adhere to the conveyor belt surface, making them difficult to clean. This not only contaminates subsequently conveyed eggshells but can also affect the transmission stability of the conveyor belt, leading to slippage, belt misalignment, and other malfunctions, increasing equipment maintenance frequency and costs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing traditional conveyor belts, which lack targeted buffer and guiding structures. When eggshells enter the conveyor belt from the feed inlet, they are prone to falling vertically, resulting in a large direct impact force between the eggshells and the conveyor belt or equipment housing. This often leads to a high eggshell breakage rate, making it difficult to meet the requirements of efficient and low-loss production. At the same time, during the conveying process, eggshells may be covered with impurities such as egg liquid, dust, and feather debris. These impurities gradually adhere to the surface of the conveyor belt, making them difficult to clean. This not only contaminates the eggshells being conveyed subsequently but may also affect the transmission stability of the conveyor belt, leading to slippage, belt deviation, and other malfunctions, increasing the frequency and cost of equipment maintenance. Therefore, this invention proposes an eggshell conveying device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An eggshell conveying device includes a feeding mechanism, a conveying mechanism, and a cleaning mechanism. The feeding mechanism includes a buffer hopper with a silicone buffer layer attached to its inner wall. The feeding hopper is connected to an arc-shaped distribution plate via an angle adjustment structure. The conveying mechanism includes two parallel silicone conveyor belts, with a mounting plate fixedly connected to the bottom of each conveyor belt. The cleaning mechanism includes a silicone cleaning brush that fits into the silicone conveyor belts and a liquid receiving tank below it. The cleaning brush and the liquid receiving tank are detachably connected to the frame of the silicone conveyor belts via snap-fit ​​connectors.

[0006] Preferably, the angle adjustment structure includes a bidirectional lead screw rotatably connected to the inner wall of the feed hopper, a movable sleeve threaded onto the bidirectional lead screw, a connecting rod rotatably connected to the top of the movable sleeve, a lifting block rotatably connected to the end of the connecting rod away from the movable sleeve, a pulley rotatably connected to the outer wall of the lifting block near the arc-shaped distribution plate, and a slot for inserting and rotating a tool at the end of the bidirectional lead screw that passes through the outer wall of the feed hopper.

[0007] Preferably, the pulley abuts against the inner wall of the arc-shaped material distribution plate, so that when the pulley moves upward, it can push the opening and closing angle of the arc-shaped material distribution plates on both sides. The bottom of the movable sleeve is fixedly connected to a limiting mechanism, which can restrict the movable sleeve from moving linearly along the axial direction.

[0008] Preferably, the feed hopper is fixedly installed on the top of the silicone conveyor belt, and a separator block is fixedly connected to the inner wall of the feed hopper outlet to divide the outlet into two, with the two parallel silicone conveyor belts respectively located below the two outlets.

[0009] Preferably, a fixing plate is fixedly connected to both outer walls of the mounting plate, a drive motor is fixedly mounted on the fixing plate, a transmission shaft is fixedly connected to the output end of the drive motor, a guide rail is fixedly connected to the top of the mounting plate, and a handle is fixedly connected to the outer wall of the liquid receiving tank.

[0010] Preferably, the liquid receiving tank is slidably connected to the guide rail, and two cleaning brushes are connected to the drive shaft via snap-fit ​​connectors.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. In use, the feeding mechanism of this utility model adopts a buffer feeding hopper with a silicone buffer layer on the inner wall. When the eggshells enter from the feeding port, the silicone buffer layer can weaken the impact force of the falling eggshells in advance, avoiding the problem of eggshells directly hitting the equipment shell in traditional conveying. At the same time, the feeding hopper is connected to an arc-shaped distribution plate through an angle adjustment structure, which can flexibly adjust the distribution angle according to the eggshell conveying volume, and evenly distribute the eggshells to the subsequent conveying mechanism to prevent eggshells from accumulating and colliding. The double protection greatly reduces the breakage rate of eggshells during the conveying process, meets the production requirements for the integrity of raw materials, and reduces the raw material loss caused by breakage.

[0012] 2. In use, this utility model utilizes a silicone cleaning brush attached to the silicone conveyor belt within the cleaning mechanism to wipe and clean the belt surface in real time during conveyor belt operation. This promptly removes adhering egg liquid, dust, feather debris, and other impurities, preventing the accumulation of impurities that contaminate subsequently conveyed eggshells, avoiding cross-contamination, and ensuring the hygiene quality of the eggshells. The liquid receiving tank below simultaneously collects liquid impurities dripping during the cleaning process, preventing impurities from contaminating the surrounding environment. Furthermore, the cleaning brush and liquid receiving tank are detachably connected to the frame via snap-fit ​​connectors, simplifying disassembly and installation without the need for complex tools, significantly reducing cleaning and maintenance time. The detachable design also facilitates the replacement of the cleaning brush and thorough cleaning of the liquid receiving tank, reducing the manpower and time costs of equipment maintenance and lowering overall production and operating costs.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Reference Figures 1-5An eggshell conveying device includes a feeding mechanism 1, a conveying mechanism 2, and a cleaning mechanism 3. The mechanisms work together to achieve orderly conveying and cleaning of materials.

[0017] The feeding mechanism 1 includes a buffered feeding hopper 4. A silicone buffer layer is fitted onto the inner wall of the feeding hopper 4. This silicone buffer layer is made of food-grade silicone with a Shore hardness of 50-60 and a thickness of 3-5mm, effectively reducing the impact of falling materials and preventing material adhesion. The feeding hopper 4 is connected to an arc-shaped distribution plate 5 via an angle adjustment structure. The arc-shaped distribution plate 5 is made of 304 stainless steel, and its curvature matches the outlet curvature of the feeding hopper 4. The edges are rounded to prevent material jamming.

[0018] The angle adjustment structure includes a bidirectional lead screw 10, which is rotatably connected to the inner wall of the feed hopper 4 via bearings. The threads at both ends of the lead screw 10 have opposite directions and a pitch of 2-4 mm. Two symmetrically arranged movable sleeves 11 are threaded onto the bidirectional lead screw 10. A connecting rod 12 is rotatably connected to the top of each movable sleeve 11 via a pin. A lifting block 13 is rotatably connected to the end of the connecting rod 12 away from the movable sleeve 11 via a pin. A pulley 14, made of polytetrafluoroethylene (PTFE) with an outer diameter of 15-20 mm, is rotatably connected to the outer wall of the lifting block 13 near the arc-shaped distribution plate 5 via an axle. The pulley 14 has a slot 20, which is hexagonal in shape, allowing a tool to be inserted and rotated. The distance between opposite sides of the slot 20 is 8-12 mm.

[0019] The pulley 14 abuts against the inner wall of the arc-shaped material distribution plate 5. When the pulley 14 moves upward, it can push the arc-shaped material distribution plates 5 on both sides to adjust the opening and closing angle, with an adjustment range of 15°-60°. The bottom of the movable sleeve 11 is fixedly connected to a limiting mechanism. The limiting mechanism includes a limiting slider fixedly connected to the movable sleeve 11 and a limiting guide rail fixedly connected to the inner wall of the feed hopper 4. The limiting slider and the limiting guide rail slide together to restrict the movable sleeve 11 from moving linearly along the axial direction and prevent it from rotating synchronously with the bidirectional lead screw 10.

[0020] The feed hopper 4 is fixedly installed on the top of the silicone conveyor belt 6 by bolts. A separator block is welded and fixed to the inner wall of the outlet of the feed hopper 4. The separator block divides the outlet into two symmetrical discharge channels. The two parallel silicone conveyor belts 6 are respectively set directly below the two outlets to ensure that the material falls accurately onto the conveyor belt.

[0021] The conveying mechanism 2 includes two parallel silicone conveyor belts 6. The silicone conveyor belts 6 are made of wear-resistant silicone material with a thickness of 2-3mm and have anti-slip textures on the surface with a texture depth of 0.5-1mm. A mounting plate 7 is bolted to the bottom of the silicone conveyor belts 6. The mounting plate 7 is made of Q235 steel plate with a thickness of 5-8mm. Fixing plates 15 are welded to the outer walls of both sides of the mounting plate 7. A drive motor 16 is bolted to the fixing plate 15. The drive motor 16 is a 0.5-1.5kW geared motor, and its output end is fixedly connected to a transmission shaft 17 via a coupling. The transmission shaft 17 is rotatably connected to the mounting plate 7 via a bearing housing.

[0022] The cleaning mechanism 3 includes a silicone cleaning brush 8 that adheres to the silicone conveyor belt 6 and a liquid receiving tank 9 located below it. The bristles of the cleaning brush 8 are made of food-grade silicone filaments with a diameter of 0.1-0.3mm and a bristle length of 15-20mm, with a density of 80-100 bristles per square centimeter. The cleaning brush 8 and the liquid receiving tank 9 are detachably connected to the frame of the silicone conveyor belt 6 via snap-fit ​​connectors. The snap-fit ​​connectors include a retainer fixed to the frame and a locking block fixed to the cleaning brush 8 and the liquid receiving tank 9. The retainer and the locking block can be quickly attached and detached through elastic deformation.

[0023] A guide rail 18, model THK-SHS15, is bolted to the top of the mounting plate 7. The bottom of the liquid receiving tank 9 has a slider adapted to the guide rail 18, enabling a sliding connection between the tank and the guide rail 18. A handle 19 is welded to the outer wall of the liquid receiving tank 9, and a rubber anti-slip sleeve is fitted onto the surface of the handle 19. Two cleaning brushes 8 are connected to the drive shaft 17 via snap-fit ​​connectors. Each of the two cleaning brushes 8 corresponds to one of the two silicone conveyor belts 6, ensuring effective cleaning.

[0024] It should be noted that the specific models and specifications of the drive motor 16 and the silicone conveyor belt 6 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated here. Both can be powered by external devices and controlled to start and stop.

[0025] Working principle: The operator first feeds the eggshell material into the feed hopper 4. The silicone buffer layer reduces the impact of the fall and prevents adhesion. A tool rotating slot 20 drives the bidirectional lead screw 10, which in turn moves the movable sleeve 11 along the limiting guide rail. This movement, via the connecting rod 12 and the lifting block 13, pushes the pulley 14 up and down, thereby adjusting the opening angle (15°-60°) of the arc-shaped distribution plate 5 and controlling the material flow to the two discharge channels. The eggshells then fall accurately onto the two parallel silicone conveyor belts 6.

[0026] During the conveying process, the drive motor 16 drives the silicone conveyor belt 6 through the transmission shaft 17, smoothly conveying the material to the cleaning station. The cleaning brush 8 is in close contact with the surface of the conveyor belt, and the bristles remove residual dirt, while the waste liquid falls into the receiving tank 9 below. The receiving tank 9 can be cleaned or replaced by sliding along the guide rail 18 using the handle 19. The snap-fit ​​connector allows for quick installation and removal of the cleaning brush 8 and the receiving tank 9, achieving efficient cleaning and maintenance.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. 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.
