[0002] Potatoes are a common food in daily life. After a bumper harvest, potatoes are sorted for easy pricing. However, this sorting process has some shortcomings and areas for improvement: 1. Potato sorting is usually done manually, which is inefficient and increases the workload for workers; 2. Potatoes are sometimes bumped and damaged during sorting, affecting their appearance and subsequent marketability. Therefore, we propose a potato sorting machine. Utility Model Content

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A potato sorting machine includes a rectangular frame with several sets of round holes evenly spaced at the front end of the frame. Support legs are fixedly connected to the four corners of the lower end of the rectangular frame. An operating disc is fixedly connected to the upper left side of the front end of the rectangular frame. Three sets of baffles are fixedly connected at equal distances between the front inner wall and the rear inner wall of the rectangular frame. Four sets of tiered mechanisms are fixedly connected at equal distances at the rear end of the rectangular frame.

Several sets of rotating rollers are movably connected to the inner walls of the two sets of sleeve rings through a U-shaped rod.

[0007] By adopting the above technical solution, potatoes of different diameters can be screened out by using screening holes of different diameters on the four-group grading mechanism.

[0008] Preferably, the drive motor is fixedly connected to the rear end of the rectangular frame, the rotating cylinder is located inside the rectangular frame, and the two sets of the sleeve rings are fixedly connected to the inner wall of the rectangular frame.

[0009] By adopting the above technical solution, the position of the rotating cylinder can be fixed from the front and rear by two sets of sleeves.

[0010] Preferably, the buffer mechanism includes a U-shaped plate, a buffer pad is fixedly connected to the upper end of the U-shaped plate, a contact pad is fixedly connected to the upper end of the buffer pad, a fixing ring is fixedly connected to the left front part and the rear front part of the lower end of the U-shaped plate, and a support rod is fixedly connected to the middle of the lower inner wall of the fixing ring.

[0011] By adopting the above technical solution: the cushioning pad is made of sponge material and the contact pad is made of rubber material, the potatoes can be prevented from being bumped.

[0012] Preferably, the fixing ring is fixedly connected to the front end of the rectangular frame, the upper end of the support rod is fixedly connected to the rear part of the lower end of the spiral plate, the spiral plate is located inside the grading mechanism, and the spiral plate is inclined.

[0013] By adopting the above technical solution, the support rod supports the rear of the spiral plate to prevent the potato from falling and causing the spiral plate to fall off.

[0014] Preferably, the baffle is located between the two grading mechanisms, and the buffer mechanism is located inside the adjacent grading mechanism, with the buffer mechanism passing through the interior of the adjacent circular hole.

[0015] By adopting the above technical solution, the baffle can prevent potatoes from falling inside the rectangular frame and from sliding out of the round hole.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By setting up a grading mechanism, the rotating drum on the grading mechanism can rotate under the drive of the drive motor. The screening holes on the rotating drum can screen potatoes of similar diameter.

[0028] A potato sorting machine includes a rectangular frame 1, with several sets of round holes 2 evenly spaced at the front end of the rectangular frame 1, support legs 3 fixedly connected to the four corners of the lower end of the rectangular frame 1, an operating disc 4 fixedly connected to the upper left side of the front end of the rectangular frame 1, three sets of baffles 5 evenly spaced at the upper part between the front inner wall and the rear inner wall of the rectangular frame 1, four sets of grading mechanisms 6 evenly spaced at the rear end of the rectangular frame 1, and four sets of buffer mechanisms 7 evenly spaced at the front end of the rectangular frame 1.

[0029] In this embodiment, the grading mechanism 6 includes a rotating cylinder 61, a drive motor 62 is fixedly connected to the middle of the rear end of the rotating cylinder 61, a number of screening holes 63 are opened at equal intervals on the rotating cylinder 61, and a sleeve ring 64 is inserted and sleeved at both the front and rear of the rotating cylinder 61. A number of rotating rollers 65 are movably connected to the inner walls of the two sets of sleeve rings 64 through a U-shaped rod. The drive motor 62 is fixedly connected to the rear end of the rectangular frame 1, the rotating cylinder 61 is located inside the rectangular frame 1, and the two sets of sleeve rings 64 are fixedly connected to the inner wall of the rectangular frame 1.

[0030] With the above solution: the drive motor 62 inside the rotating drum 61 drives it to rotate, and the rotating drum 61 has screening holes 63 of different diameters, which can screen potatoes of different diameters. Compared with manual grading, it is more efficient. In addition, the rotating rollers 65 set at the front and rear can support the rotating drum 61 and prevent it from falling.

[0031] In this embodiment, the buffer mechanism 7 includes a U-shaped plate 8, with a buffer pad 9 fixedly connected to the upper end of the U-shaped plate 8, and a contact pad 10 fixedly connected to the upper end of the buffer pad 9. A fixing ring 11 is fixedly connected to the left front part and the rear front part of the lower end of the U-shaped plate 8. A support rod 12 is fixedly connected to the middle of the lower inner wall of the fixing ring 11. The fixing ring 11 is fixedly connected to the front end of the rectangular frame 1. The upper end of the support rod 12 is fixedly connected to the rear lower end of the U-shaped plate 8. The U-shaped plate 8 is located inside the grading mechanism 6 and is inclined. The baffle 5 is located between the two grading mechanisms 6. The buffer mechanism 7 is located inside the adjacent grading mechanism 6 and passes through the adjacent circular hole 2.

[0032] The above solution allows the inclined U-shaped plate 8 to facilitate the downward rolling of potatoes.

[0033] It should be noted that this utility model is a potato sorting machine. During use, harvested potatoes are first placed inside the rectangular frame 1. Then, the four-group grading mechanism 6 is driven. The rotating cylinders 61 on the four-group grading mechanism 6 are driven by the motor 62 to rotate. Each of the four rotating cylinders 61 has a screening hole 63 with a different diameter, allowing for grading and sorting of the potatoes. A baffle 5 is installed between the two grading mechanisms 6 to prevent potatoes from falling inside the rectangular frame 1. Additionally, baffles are provided at the front and rear of the rotating cylinders 61. The sleeve ring 64 with rotating roller 65 can support the front and rear of the rotating cylinder 61 to prevent the rotating cylinder 61 from falling off. After grading, the potatoes fall onto the U-shaped plate 8. The U-shaped plate 8 is set at an angle to facilitate the potatoes rolling down. At the same time, a sponge cushioning pad 9 and a rubber contact pad 10 are fixedly connected to the U-shaped plate 8 to prevent the potatoes from being bumped and affecting their subsequent appearance. The support rod 12 is fixedly connected at an angle to the fixing ring 11 and is fixedly connected to the lower rear end of the U-shaped plate 8 to support the U-shaped plate 8 from the rear.
