Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, and in particular to a high-efficiency automatic walnut shell and kernel separator. Background Technology

[0002] With the steady rise of the economy and the significant improvement of people's living standards, walnuts, with their rich nutritional value and medicinal effects, are increasingly favored by the market. The demand for walnut deep-processed products at home and abroad is showing a continuous growth trend. The importance of the core link in the primary processing of walnuts, shell and kernel separation, is becoming increasingly prominent. The efficiency and quality of this process are directly related to key indicators such as kernel loss rate and impurity rate, and thus have a decisive impact on the overall economic value of the walnut industry. As people's market demand for walnut kernels increases day by day, the high-efficiency automatic walnut shell and kernel separator has emerged in response to such demand of the times.

[0003] Walnuts are evenly fed into the separator through the feed inlet. They first enter the roller extrusion shell-breaking module, where the rotation of adjustable-gap rollers generates extrusion and friction, causing the walnut shells to crack and initially separate from the kernels. This is suitable for different varieties of walnuts, such as thin-shelled and thick-shelled ones. The mixture after shelling then enters the sorting stage. A fan on one side generates directional airflow, which uses the density difference between the shells and kernels to blow the lighter shells toward the shell collection device, while the heavier kernels fall into the screening area under the action of gravity. The roller sorting structure on the other side uses an inner wall protrusion design to separate the shells and kernels into layers due to the different coefficients of friction, significantly reducing labor costs and losses.

[0004] At present, the high-efficiency automatic walnut shell kernel separator has significantly promoted the development of the industry. However, the sorting process is difficult to maintain and clean due to its complex structure. This process integrates multiple layers of structure such as wind-powered sorting and photoelectric recognition. Dust and grease easily accumulate on the inner wall of the air duct and the impeller of the fan. The lens of the photoelectric sensor will also get dirty, affecting the performance of the equipment. During cleaning, stubborn stains mixed with grease and dust need to be treated with special cleaning agents and soft brushes. Disassembling the multi-layered structure is time-consuming and can easily damage precision parts. Therefore, the high-efficiency automatic walnut shell kernel separator is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-efficiency automatic walnut shell and kernel separator, which aims to improve the problem of difficult maintenance and cleaning caused by the complex structure of the sorting process in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-efficiency automatic walnut shell and kernel separator includes a base, a shell fixedly connected to the outer wall of the base, a connecting column fixedly connected to the top of the shell, a hopper fixedly connected to the top of the connecting column, a motor fixedly connected to one side of the shell, a rotating column fixedly connected to the drive end of the motor, an anti-clogging component fixedly connected to the outer wall of the rotating column, a motor fixedly connected to the bottom of the base, a rotating disk fixedly connected to the drive end of the motor, four protrusions fixedly connected to the top of the rotating disk, a filter plate slidably connected to the inner wall of the base, and two support columns fixedly connected to the bottom of the filter plate.

[0008] As a further description of the above technical solution:

[0009] The anti-blocking component includes multiple fixing blocks, with one side of each fixing block being fixedly connected to the outer wall of the rotating column. The inner wall of the connecting column has three grooves, with a fixing column slidably connected to the inner wall of each groove. A sliding column is fixedly connected to one side of each fixing column, and three limiting columns are slidably connected inside the connecting column. Springs are fitted onto the outer walls of each of the three limiting columns.

[0010] As a further description of the above technical solution:

[0011] The inner wall of the base has two limiting grooves, and the bottoms of the two support columns are slidably connected to the top of the rotating disk.

[0012] As a further description of the above technical solution:

[0013] Limiting blocks are fixedly connected to both sides of the filter plate, and the outer walls of the two limiting blocks are slidably connected to the inner walls of the two limiting grooves respectively.

[0014] As a further description of the above technical solution:

[0015] The outer wall of the rotating disk is rotatably connected to the inside of the base, and a hydraulic cylinder is rotatably connected to one side of the base;

[0016] As a further description of the above technical solution:

[0017] A rotating plate is rotatably connected to the outer wall of the housing, and a fixing plate is fixedly connected to the outer wall of the housing;

[0018] As a further description of the above technical solution:

[0019] One side of the hydraulic cylinder is rotatably connected to the outer wall of the rotating plate, and one side of the rotating plate is in contact with one side of the fixed plate;

[0020] As a further description of the above technical solution:

[0021] The base has a kernel outlet groove on one side and a shell outlet groove on the other side.

[0022] As a further description of the above technical solution:

[0023] One side of the spring is fixedly connected to the inner wall of the groove, and the other side of the spring is fixedly connected to the outer wall of the fixed column. The bottom of the sliding column is slidably connected to the outer wall of the rotating column, and both sides of the rotating column are rotatably connected to the inside of the housing.

[0024] This utility model has the following beneficial effects:

[0025] 1. In this utility model, by activating the hydraulic cylinder located on one side of the base, the piston rod extends and retracts, causing the rotating plate to rotate along the hinge axis. This causes the rotating plate to tilt relative to the shell, allowing the shell-core mixture that has been separated inside the shell to slide down the rotating plate onto the surface of the filter plate below under the action of gravity. At this time, the second motor is activated, and its output shaft drives the rotating disk to rotate at a constant speed. The protrusion fixed to the rotating disk then performs a circular motion. When the support column (connected to the bottom of the filter plate) contacts the protrusion, a vertical displacement occurs due to the height difference of the protrusion. Simultaneously, due to the sliding fit between the limiting block and the limiting groove at the bottom of the shell, the filter plate remains stable during the up-and-down movement. To prevent shaking and displacement, the rapid reciprocating motion of the filter plate generates high-frequency vibration, causing smaller kernels in the kernel-shell mixture to fall through the filter holes into the cavity and be removed from the kernel outlet slot. Larger shells remain on the surface of the filter plate and slide out of the outlet slot into the base with the vibration, thus achieving a separation effect. After the operation, it is only necessary to disassemble the filter plate and rinse or sweep away the shells and debris remaining on its surface. There is no need to disassemble the complex internal structure, which greatly simplifies the cleaning process. This not only reduces the difficulty of maintenance but also reduces the wear and tear caused by frequent disassembly of core components, significantly reducing the cost of equipment use while improving operational efficiency and stability.

[0026] 2. In this utility model, a motor on one side of the housing is opened, and its driving force drives the rotating column to make a circular motion. The outer surface of the rotating column cooperates with the inner wall of the housing to squeeze and shear the walnuts to separate the shells and kernels. The fixed block fixed to the outer wall of the rotating column makes a circular motion simultaneously. When it passes the bottom of the sliding column, its protruding part contacts the sliding column and creates a height difference, which pushes the sliding column to compress the spring and move it upward. After the fixed block rotates away, the spring releases its elastic potential energy to reset the sliding column. Through the linkage of the fixed column, the limiting column and the spring, a mechanical impact force is generated in the reciprocating motion of the sliding column. When walnuts of different sizes enter the connecting column and cause blockage, the periodic impact of the sliding column can automatically break the blockage point. The spring assists the sliding column to reset and avoids the consequence of the sliding column being unable to move due to blockage. This significantly improves the adaptability of the equipment to walnut sizes, greatly reduces the blockage rate, and can keep the feeding smooth without manual intervention, greatly improving the raw material utilization rate and continuous operation capability.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1 to 3This utility model provides an embodiment of a high-efficiency automatic walnut shell and kernel separator, comprising a base 1, which serves as the supporting foundation for the entire device. A shell 2 is fixedly connected to the outer wall of the base 1, forming the main working space for walnut shell and kernel separation. A connecting column 4 is fixedly connected to the top of the shell 2, and a hopper 5 is fixedly connected to the top of the connecting column 4. The connecting column 4 serves as the channel for walnuts to enter the shell 2 from the hopper 5. Its smooth inner wall design reduces resistance when the walnuts fall. A motor 3 is fixedly connected to one side of the shell 2, and a rotating column 16 is fixedly connected to the drive end of the motor 3, serving as the power source for the rotating column 16. An anti-blocking component is fixedly connected to the outer wall of the rotating column 16, which is a key structure for preventing feed blockage. A second motor 6 is fixedly connected to the bottom of the base 1, and a rotating disk 7 is fixedly connected to the drive end of the second motor 6, causing the rotating disk 7 to rotate in a circular motion driven by the second motor 6. A connecting column 5 is fixedly connected to the top of the rotating disk 7. Four protrusions 8 are attached to the inner wall of the base 1, and a filter plate 10 is slidably connected to it. The surface of the filter plate 10 is provided with sieve holes of a specific diameter, which can screen out walnut kernels. Two support columns 9 are fixedly connected to the bottom of the filter plate 10. The anti-clogging component includes multiple fixing blocks 17. The sides of the multiple fixing blocks 17 that are close to each other are fixedly connected to the outer wall of the rotating column 16. As the rotating column 16 rotates, the fixing blocks 17 move synchronously. The inner wall of the connecting column 4 is provided with three grooves 20. The inner wall of the grooves 20 is slidably connected to the fixing columns 19. The sides of the three fixing columns 19 that are close to each other are fixedly connected to the sliding column 18. The sliding column 18 directly contacts the walnuts and clears the blocked walnuts by moving up and down. The inside of the connecting column 4 is slidably connected to three limiting columns 21. The outer wall of each of the three limiting columns 21 is fitted with a spring 22. The limiting columns 21 play a limiting and guiding role for the springs 22 to prevent them from deviating during movement. The springs 22 provide a restoring elastic force to ensure that the sliding column 18 can move back and forth stably.

[0035] Reference Figures 2 to 4The inner wall of the base 1 has two limiting grooves 11. The bottoms of the two support columns 9 are slidably connected to the top of the rotating disk 7 to bear the force brought by the protrusion 8. Limiting blocks 12 are fixedly connected to both sides of the filter plate 10. The outer walls of the two limiting blocks 12 are slidably connected to the inner walls of the two limiting grooves 11 to ensure that the filter plate 10 does not undergo horizontal displacement when vibrating. The outer wall of the rotating disk 7 is rotatably connected to the inside of the base 1 to ensure that the rotating disk 7 can rotate smoothly. A hydraulic cylinder 15 is rotatably connected to one side of the base 1. A rotating plate 13 is rotatably connected to the outer wall of the housing 2. The rotating plate 13 can rotate to change its angle and guide the shell-core mixture into the filter plate 10. A fixing plate 14 is fixedly connected to the outer wall of the housing 2. The fixing plate 14 is used to support the rotating plate 13 and limit its rotation angle. One side of the hydraulic cylinder 15... The rotating plate 13 is rotatably connected to the outer wall of the rotating plate 13. The hydraulic cylinder 15 provides rotational driving force to the rotating plate 13 through hydraulic power. One side of the rotating plate 13 is in contact with one side of the fixed plate 14 to ensure the accuracy of the rotation angle of the rotating plate 13. A kernel outlet groove 23 is provided on one side of the base 1 for collecting the separated walnut kernels. A shell outlet groove 24 is provided on the other side of the base 1 for discharging the separated walnut shells. One side of the spring 22 is fixedly connected to the inner wall of the groove 20, and the other side is fixedly connected to the outer wall of the fixed column 19 to provide elastic force for the reset of the sliding column 18. The bottom of the sliding column 18 is slidably connected to the outer wall of the rotating column 16 to ensure normal up and down movement when in contact with the fixed block 17. Both sides of the rotating column 16 are rotatably connected to the inside of the housing 2 to ensure the stability of the rotation of the rotating column 16.

[0036] Working Principle: A large quantity of walnuts is poured into the hopper 5, allowing them to enter the shell 2 along the connecting column 4. The motor 3, located on one side of the shell 2, is activated, driving the rotating column 16 in a circular motion. This allows the rotating column 16 and the shell 2 to work together to separate the walnut kernels from their shells. Simultaneously, the fixed block 17 rotates periodically with the rotating column 16, and the sliding column 18 is positioned along the path of the fixed block 17. When the sliding column 18 contacts the fixed block 17, a height difference is created. At this point, the fixed column 19, the limiting column 21, and the spring 22 work together. The fixed column 19 moves with the sliding column 18, compressing the spring 22. When the sliding column 18 leaves the fixed block 17, the height difference disappears, and the elastic potential energy of the spring 22 is released, allowing the sliding column 18 to move stably downwards, thus achieving... Even when walnuts of different sizes become stuck in the connecting column 4, the device can still reliably clear the blockage, greatly improving the utilization rate of the entire device. Activating the hydraulic cylinder 15 located on one side of the base 1 moves the rotating plate 13, causing it to rotate relative to the housing 2. This allows the separated kernels inside the housing 2 to fall onto the surface of the filter plate 10 through the rotating plate 13. Activating the second motor 6 drives the rotating disk 7 to rotate, causing the protrusion 8 to move synchronously with the rotation of the rotating disk 7. When the support column 9 contacts the protrusion 8, a height difference is created. Due to the cooperation of the limiting block 12 and the limiting groove 11, the filter plate 10 achieves stable and rapid up-and-down movement, thereby separating the kernels. After operation, cleaning and maintenance only requires cleaning the surface of the filter plate 10, significantly reducing the overall operating cost of the device.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
