Description

A potato grading and screening device Technical Field

[0001] This utility model relates to the field of potato screening technology, specifically a potato grading and screening device. Background Technology

[0002] In the potato planting and processing industry chain, grading and screening is a crucial link. As an important crop widely planted around the world, potatoes have a variety of uses, including fresh consumption and processing into many food and industrial products such as potato chips, French fries, and starch.

[0003] Traditional potato grading and screening methods have many drawbacks. Manual screening is labor-intensive and time-consuming, inefficient, and struggles to maintain consistent screening standards. Workers are prone to fatigue from prolonged work, leading to decreased screening accuracy and potentially mixing substandard potatoes with products of different grades, thus affecting product quality and market competitiveness. Therefore, we propose a potato grading and screening device. Summary of the Invention

[0004] The purpose of this invention is to provide a potato grading and screening device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a potato grading and screening device, comprising a mounting platform, a coarse screen and a fine screen, wherein a rotating column is rotatably mounted on the top surface of the mounting platform, and a first turntable and a second turntable are mounted on the outer side of the rotating column, the second turntable is located above the first turntable, and a plurality of mounting holes are opened on the surface of the second turntable, wherein the coarse screen and the fine screen are respectively installed in different mounting holes;

[0006] The top surface of the first turntable is equipped with multiple receiving boxes. The top surface of the mounting platform is equipped with a drive assembly for rotating the rotating column. A support rod is installed on the outside of the mounting platform. A horizontal plate is installed on the upper end of the support rod. A sliding plate is slidably installed on the outside of the horizontal plate. A limit frame is installed on one end of the sliding plate. The bottom surface of the limit frame contacts the top surface of the second turntable. A limit hole is opened on the top surface of the sliding plate. A motion assembly for driving the sliding plate is installed on the top surface of the horizontal plate.

[0007] Preferably, the drive assembly includes a first motor, a second gear, and a first gear. The first gear is fixedly mounted on the outside of the rotating column, the first motor is mounted on the top surface of the mounting platform, the second gear is mounted on the output end of the first motor, and the second gear meshes with the first gear.

[0008] Preferably, the motion component includes a U-shaped mounting bracket, which is mounted on the top surface of the horizontal plate. A second motor is mounted on the top surface of the U-shaped mounting bracket, and the output end of the second motor movably passes through the U-shaped mounting bracket. A connecting plate is fixedly mounted on the output end of the second motor, and a limit block is mounted on the bottom surface of the connecting plate, with the limit block passing through a limit hole.

[0009] Preferably, the limiting block is cylindrical.

[0010] Preferably, the outer diameter of the limiting block matches the width of the limiting hole.

[0011] Preferably, the number of the receiving boxes is the same as the number of the mounting holes, and the positions of the receiving boxes and the mounting holes are perpendicular to each other.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This potato grading and screening device, when the switch of the first motor is turned on, drives the second gear and the first gear to rotate. The first gear drives the rotating column, the first turntable and the second turntable to rotate, so that the fine screen, the coarse screen and the empty mounting hole move to the position opposite the limit frame without moving the limit frame, thus completing the screening of potatoes of different sizes. It can screen potatoes of small, medium and large sizes, and the screening is relatively convenient.

[0014] 2. In this potato grading and screening device, turning on the switch of the second motor drives the connecting plate and the limiting block to rotate. The limiting block passes through the inside of the limiting hole, thereby driving the sliding plate to slide back and forth on the outside of the horizontal plate. The sliding plate drives the limiting frame to move back and forth, thereby shaking the potatoes in the limiting frame and ensuring the screening efficiency of the device.

[0019] 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.

[0020] Example 1

[0021] Please refer to Figures 1-3. This utility model provides a potato grading and screening device, including a mounting platform 1, a coarse screen 6 and a fine screen 7. A rotating column 2 is rotatably mounted on the top surface of the mounting platform 1. A first turntable 3 and a second turntable 4 are mounted on the outside of the rotating column 2. The second turntable 4 is located above the first turntable 3. A plurality of mounting holes 5 are opened on the surface of the second turntable 4. The coarse screen 6 and the fine screen 7 are respectively installed in different mounting holes 5.

[0022] Multiple receiving boxes 8 are installed on the top surface of the first turntable 3. A drive assembly for rotating the rotating column 2 is installed on the top surface of the mounting platform 1. A support rod 12 is installed on the outside of the mounting platform 1. A horizontal plate 13 is installed on the upper end of the support rod 12. A sliding plate 14 is slidably installed on the outside of the horizontal plate 13. A limit frame 15 is installed on one end of the sliding plate 14. The bottom surface of the limit frame 15 contacts the top surface of the second turntable 4. A limit hole 16 is opened on the top surface of the sliding plate 14. A motion assembly for driving the sliding plate 14 is installed on the top surface of the horizontal plate 13.

[0023] Specifically, the motion component can cause the limiting frame 15 to shake, thereby causing the potatoes to shake, so that the potatoes can be screened quickly. By controlling the coarse screen 6, fine screen 7 and empty mounting hole 5 to move below the limiting frame 15, the potatoes are screened in multiple stages.

[0024] The drive assembly includes a first motor 10, a second gear 11, and a first gear 9. The first gear 9 is fixedly installed on the outside of the rotating column 2. The first motor 10 is installed on the top surface of the mounting platform 1. The second gear 11 is installed on the output end of the first motor 10. The second gear 11 meshes with the first gear 9. When the switch of the first motor 10 is turned on, the second gear 11 and the first gear 9 are driven to rotate. The first gear 9 drives the rotating column 2, the first turntable 3, and the second turntable 4 to rotate.

[0025] The motion component includes a U-shaped mounting bracket 17, which is mounted on the top surface of the horizontal plate 13. A second motor 18 is mounted on the top surface of the U-shaped mounting bracket 17. The output end of the second motor 18 moves through the U-shaped mounting bracket 17. A connecting plate 19 is fixedly mounted on the output end of the second motor 18. A limit block 20 is mounted on the bottom surface of the connecting plate 19. The limit block 20 passes through the limit hole 16 and is cylindrical. The outer diameter of the limit block 20 matches the width of the limit hole 16. When the switch of the second motor 18 is turned on, the connecting plate 19 and the limit block 20 are rotated, thereby causing the sliding plate 14 to slide back and forth on the outside of the horizontal plate 13. The sliding plate 14 causes the limit frame 15 to move back and forth, thereby shaking the potatoes inside the limit frame 15.

[0026] Among them: the number of receiving boxes 8 is the same as the number of mounting holes 5, the positions of receiving boxes 8 and mounting holes 5 are perpendicular to each other, and the receiving boxes 8 can catch the potatoes falling into the mounting holes 5.

[0027] Working Principle: This utility model is a potato grading and screening device. In use, potatoes are placed in the limiting frame 15. The second motor 18 is turned on, causing the connecting plate 19 and the limiting block 20 to rotate. The limiting block 20 passes through the limiting hole 16, thereby causing the sliding plate 14 to slide back and forth on the outside of the horizontal plate 13. The sliding plate 14 causes the limiting frame 15 to move back and forth, thus shaking the potatoes inside the limiting frame 15. Smaller potatoes pass through the fine screen 7 and fall into the corresponding receiving box 8. Then, the first motor 10 is turned on, causing the second gear 11 and the first gear 9 to rotate. The rotating column 2 rotates, which in turn rotates the first turntable 3 and the second turntable 4. This causes the coarse screen 6 to move to below the limiting frame 15. The coarse screen 6 has large gaps on its surface, allowing larger potatoes to pass through it and fall into the corresponding receiving box 8. The remaining potatoes in the limiting frame 15 are large potatoes. The second turntable 4 is then rotated, causing the empty mounting hole 5 to move to the corresponding position in the limiting frame 15. This allows potatoes to pass through the empty mounting hole 5 and fall into the corresponding receiving box 8, completing the potato grading and screening process. During this process, there is no need to transfer the potatoes in the limiting frame 15.

[0029] Although the present invention 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 invention should be included within the protection scope of the present invention.
