[0049] Potatoes are put into the box body 34 through the feed port 35. The potatoes can roll smoothly from high to low by utilizing the gravity of the potatoes themselves and the guiding effect of the spiral structure. After the potatoes first enter the first spiral plate 14, they are first preliminarily screened. Smaller potatoes fall through the first potato leakage hole 141 and the multiple first sorting rollers 21 arranged at a first pitch on the first spiral plate 14 and enter the first feeding assembly 31 for transportation. Larger potatoes fall through the second potato leakage hole 151 and the multiple second sorting rollers 22 arranged at a second pitch on the second spiral plate 15, and the multiple third sorting rollers arranged at a third pitch on the third spiral plate 16 and the third potato leakage hole 161, and enter the second feeding assembly 32 and the third feeding assembly 33 for transportation respectively. Potatoes of different sizes are screened out and collected by the collection boxes respectively provided at the ends of the first feeding assembly 31, the second feeding assembly 32 and the third feeding assembly 33, thereby avoiding the problem of screening errors.

[0050] In this embodiment, please refer to Figures 2 to 4 , the first feeding assembly 31, the second feeding assembly 32 and the third feeding assembly 33 have the same structure;

[0051] The first feeding assembly 31 includes a spiral span plate 311, two spiral arc plates 312, a spiral bottom plate 313, two side plates 314 and a feeding tube 315, which are arranged across the two first spiral rods 24. The bottom width of the spiral span plate 311 is greater than the bottom width of the first spiral plate 14. The two ends of the two spiral arc plates 312 are fixedly connected to the two ends of the width direction of the spiral span plate 311 and the two ends of the width direction of the spiral bottom plate 313, respectively. The two ends of the two side plates 314 are fixedly connected to the two ends of the spiral bottom plate 313 and the bottom of the first spiral plate 14, respectively. The spiral span plate 311, the spiral bottom plate 313, the two spiral arc plates 312 and the spiral bottom plate 313 are fixedly connected to the two ends of the width direction of the spiral span plate 311 and the two ends of the width direction of the spiral bottom plate 313. The plate 312 and the two side plates 314 enclose a feeding space 316, and the feeding pipe 315 is located on the lower end side of the spiral bottom plate 313 and is connected to the feeding space 316; the spiral cross-plate 311 of the second feeding assembly 32 is spanned above the two second spiral rods 25, and the two ends of the side plates 314 are respectively fixedly connected to the two ends of the spiral bottom plate 313 and the bottom of the second spiral plate 15; the spiral cross-plate 311 of the third feeding assembly 33 is spanned above the two third spiral rods 26, and the two ends of the side plates 314 are respectively fixedly connected to the two ends of the spiral bottom plate 313 and the bottom of the third spiral plate 16.

[0052] The first feeding assembly 31, the second feeding assembly 32, and the third feeding assembly 33 correspond to the first spiral plate 14, the second spiral plate 15, and the third spiral plate 16, respectively, so that the sorted potatoes can be transported separately, thereby ensuring that they can be smoothly transported to the collection frame. The spiral cross plate 311, the spiral base plate 313, the two spiral curved plates 312, and the two side plates 314 cooperate to form a feeding space 316. The feeding pipe 315 is located at the lower end of the spiral base plate 313 and is connected to the feeding space 316. When potatoes are sorted by the first spiral plate 14, the second spiral plate 15, and the third spiral plate 16, the feeding space 316 can provide a stable conveying environment for the potatoes, improving the accuracy and stability of the conveying.

[0053] In this embodiment, please refer to Figure 3 and Figure 4 The feeding tube 315 is an arc-shaped structure. When potatoes enter the arc-shaped feeding tube 315 from the feeding space 316, the arc-shaped tube wall can provide a soft buffer for the potatoes, and the arc-shaped feeding tube 315 can better guide the flow of potatoes.

[0055] Working principle: When in use, potatoes are put into the box body 34 through the feed port 35. The potatoes can roll smoothly from high to low by utilizing the gravity of the potatoes themselves and the guiding effect of the spiral structure. After the potatoes first enter the first spiral plate 14, they are first preliminarily screened. The smaller potatoes fall through the first sorting rollers 21 arranged at a first pitch on the first spiral plate 14 and the first potato leakage hole 141 and enter the first feeding assembly 31 for transportation. The larger potatoes fall in turn through the second sorting rollers 22 arranged at a second pitch on the second spiral plate 15 and the second potato leakage hole 151, and the third sorting rollers arranged at a third pitch on the third spiral plate 16 and the third potato leakage hole 161. They enter the second feeding assembly 32 and the third feeding assembly 33 for transportation respectively, and potatoes of different sizes are screened out. A feeding space 316 is formed by the cooperation of the spiral cross plate 311, the spiral bottom plate 313, the two spiral arc plates 312 and the two side plates 314. The feeding pipe 315 is located on the lower end of the spiral bottom plate 313 and is connected to the feeding space 316. When potatoes are sorted out on the first spiral plate 14, the second spiral plate 15 and the third spiral plate 16 respectively, the feeding space 316 can provide a stable transportation environment for the potatoes. When the potatoes enter the arc-shaped feeding pipe 315 from the feeding space 316, the arc-shaped tube wall can provide a soft buffer for the potatoes, so that they can be smoothly transported to the collection frame for collection.

[0056] In summary, the present invention secures the first and third spiral plates 14 and 16 to the ends of the second spiral plate 15, and arranges a plurality of first sorting rollers 21, a plurality of second sorting rollers 22, and a plurality of third sorting rollers 23 on the first spiral plate 14, the second spiral plate 15, and the third spiral plate 16 at first, second, and second spacings, respectively. Utilizing the weight of the potatoes themselves and the guiding effect of the spiral structure, the potatoes can roll smoothly from a high position to a low position, allowing potatoes of different sizes to pass through the first spacing between adjacent first sorting rollers 21, the second spacing between adjacent second sorting rollers 22, and the third spacing between adjacent third sorting rollers 23, respectively, thereby achieving the effect of sorting potatoes of different sizes. By having the first spacing smaller than the second spacing, and the second spacing smaller than the third spacing, the potatoes are gradually separated during the sorting process, improving the accuracy and efficiency of the sorting. The first, second, and third potato holes 141, 151, and 161, arranged at first, second, and third intervals on the first, second, and third spiral plates 14, 15, 16, respectively, allow potatoes of varying sizes to be sorted more quickly, improving sorting efficiency and enhancing uniform flow and stability during transport. Therefore, the present invention effectively overcomes the shortcomings of the prior art and possesses high industrial value.
