[0002] In the pre-planting treatment of potatoes, precise grading and screening of seed potatoes or commercial potatoes is a key step to ensure planting quality and increase yield.

[0003] A search revealed a prior art device and method for potato seed selection (Publication No.: CN118751548A), comprising a base box, with a partition fixedly connected inside the base box, forming a residue collection trough and a seed collection trough with the base box and the partition; a bracket fixedly connected to the base box, a vertical groove fixedly connected to the bracket, an industrial camera fixedly connected to the bracket, a mounting frame fixedly connected to the bracket, a servo motor fixedly connected to the mounting frame, and a weighing groove fixedly connected to the output shaft of the servo motor; a motor fixedly connected to the bracket via a motor bracket, and a transmission gear connected to the bracket bearings of a symmetrical large gear. While such equipment achieves automated sorting, its structure is typically complex, relying on multiple precision sensors and actuators, resulting in high manufacturing and maintenance costs. More importantly, the size and shape of its sorting channels are usually fixed, making it difficult to flexibly adapt to the diverse size requirements of potatoes under different varieties and planting conditions, thus exhibiting poor versatility. Therefore, there is an urgent need for a potato planting screening device with a relatively simple structure, controllable cost, and the ability to flexibly adjust sorting accuracy to adapt to different grading standards.

[0004] Therefore, we propose a potato planting screening device. Utility Model Content

[0018] A potato planting screening device, such as Figure 1 and Figure 2 As shown, it includes: The outer casing 10 has a vibrating screen 12 installed inside it. Below the vibrating screen 12, there is a collection box 11 that can be pulled out. Inside the outer casing 10, there are two slide rails that are fixed to limit the linear movement of the collection box 11. The collection box 11 is slidably mounted on the slide rails and forms a box with an open top. Multiple partitions are installed inside the collection box 11, and the collection box 11 forms multiple independent collection chambers through the partitions. In this design, the top of the outer casing 10 is provided with a window for feeding materials. The window is located directly above the vibrating screen 12. The potatoes are vibrated and deslimed by the vibrating screen 12, and the potatoes roll off the vibrating screen 12 to one side and are discharged.

[0019] like Figure 3 , Figure 4 and Figure 5 As shown, a sorting structure is set on one side of the vibrating screen 12 for seed selection. The sorting structure includes a mounting base 20, a first conveying roller 21, and a second conveying roller 22. The mounting base 20 is fixedly installed inside the outer casing 10. Both the first conveying roller 21 and the second conveying roller 22 are mounted on the mounting base 20. The first conveying roller 21 and the second conveying roller 22 together form a sorting channel with adjustable width and taper. The sorting structure also includes a rotating base 23. The second conveying roller 22 is rotatably connected to the rotating base 23. The rotating base 23 is movably mounted on the mounting base 20. A motor is set on one side of the rotating base 23 and the mounting base 20 respectively to drive the first conveying roller 21 and the second conveying roller 22 to rotate. The sorting structure also includes a sliding base 24, which is slidably connected to the mounting base 20. The sliding base 24 can approach the first conveying roller. 21. Adjust the position of the second conveyor roller 22. The rotating seat 23 is rotatably connected to the top of the sliding seat 24. The top of the mounting seat 20 is provided with a slide groove. The sliding seat 24 is slidably disposed in the slide groove. The rotating seat 23 is axially connected to the sliding seat 24 through a plane bearing. The sorting structure also includes an electric push rod 25 and a servo motor 26. The electric push rod 25 is fixedly installed to the mounting seat 20. The sliding seat 24 is driven by the electric push rod 25 to adjust its linear position. The servo motor 26 is fixedly installed to the sliding seat 24. The rotating seat 23 is adjusted to adjust its circumferential position through the servo motor 26. The electric push rod 25 is fixed to the bottom of the mounting seat 20 through a bracket. The output shaft of the electric push rod 25 is fixedly connected to one side of the sliding seat 24 through a flange. The servo motor 26 is fixedly installed at the bottom of the sliding seat 24. The output shaft of the servo motor 26 is connected to the rotating seat 23 through a coupling. In this scheme, the collection box 11 is located directly below the first conveying roller 21 and the second conveying roller 22. The collection box 11 has multiple independent chambers for collecting potatoes of corresponding sizes. By setting up sorting channels with adjustable spacing and taper, the potatoes rolling off the vibrating screen 12 can be sorted evenly according to size. That is, smaller potatoes will fall into the leftmost collection chamber of the collection box 11, and the largest potatoes will fall into the rightmost collection chamber of the collection box 11. To adjust the width of the sorting channel, the electric push rod 25 and the servo motor 26 are connected to the PLC controller. The output shaft of the electric push rod 25 pulls the sliding seat 24 to slide along the groove of the mounting base 20. The width of the sorting channel can be adjusted by bringing the second conveying roller 22 closer to the first conveying roller 21. The output shaft of the servo motor 26 drives the rotating seat 23 to rotate, which in turn drives the second conveying roller 22 to swing at a certain angle. At this time, the second conveying roller 22 forms a certain angle with the first conveying roller 21, and the taper of the sorting channel formed by the first conveying roller 21 and the second conveying roller 22 can be adjusted. The two motors on one side of the mounting base 20 and the rotating seat 23 drive the first conveying roller 21 and the second conveying roller 22 to rotate relative to each other. Silicone sleeves can be fitted on the first conveying roller 21 and the second conveying roller 22, and potatoes can be conveyed and sorted between the first conveying roller 21 and the second conveying roller 22.

[0020] The working principle of this utility model is as follows: Initial preparation and feeding: According to the target size specifications of the potatoes to be sorted, the operator sets the parameters through an external PLC controller. The controller commands the electric push rod 25 to move, pushing the sliding seat 24 to move along the slide groove of the mounting seat 20, thereby adjusting the initial distance between the second conveying roller 22 and the first conveying roller 21. At the same time, the controller commands the servo motor 26 to move, driving the rotating seat 23 to rotate, causing the second conveying roller 22 to deflect at a certain angle, so that it forms a V-shaped or A-shaped sorting channel with a specific taper with the first conveying roller 21.

[0021] Vibration cleaning and conveying: The potatoes to be screened are poured into the feed port at the top of the outer shell 10, so that they fall onto the vibrating screen 12. The high-frequency vibration of the vibrating screen 12 can effectively shake off the soil and impurities attached to the surface of the potatoes and drive the potatoes to roll evenly and in a single layer towards the sorting structure.

[0022] Precise grading and collection: Potatoes rolling off the vibrating screen 12 enter the sorting channel consisting of the first conveying roller 21 and the second conveying roller 22. Two independent motors drive the two conveying rollers to rotate in opposite directions, carrying and conveying the potatoes forward. Smaller potatoes will fall first from the narrower entrance section of the sorting channel. As the channel width gradually increases along the conveying direction (determined by the taper), medium-sized potatoes fall in the middle section of the channel. The largest potatoes are conveyed to the very end of the channel before falling. All the fallen potatoes fall into different collection chambers divided by partitions in the collection box 11 directly below, completing the precise grading by size.

[0023] Adjustment and maintenance: When it is necessary to change the sorting specifications, simply repeat the above adjustment steps. The whole process is quick and easy. After the operation is completed, the collection box 11 can be easily pulled out along the slide rail for centralized processing of graded potatoes. The silicone sleeve on the conveyor roller provides sufficient friction for effective conveying and avoids mechanical damage to the potato skin caused by rigid contact.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
