Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, and more specifically, to a potato impurity removal and grading machine. Background Technology

[0002] As one of the world's most important food crops, the post-harvest processing of potatoes directly impacts product quality and market value. Traditional manual sorting methods are inefficient, labor-intensive, and struggle to achieve accurate grading. While existing impurity removal and grading equipment has improved efficiency to some extent, it still suffers from several problems: firstly, the impurity removal effect is unsatisfactory, with incomplete separation of mud and vines; secondly, the equipment has a complex structure, requiring a separate grading machine, resulting in transportation costs and low production efficiency. Therefore, developing a low-cost, high-efficiency post-harvest potato impurity removal and grading machine for immediate impurity removal and grading after potato harvest is of significant practical importance. Utility Model Content

[0003] The purpose of this utility model is to provide a potato impurity removal and grading machine that can solve the problems of incomplete impurity removal, high operating costs and complex equipment structure in the existing technology.

[0004] This utility model provides a technical solution:

[0005] A potato grading and impurity removal machine includes a frame, a drive unit, a transmission unit, a feed hopper, a grading assembly, and a potato vine collecting hopper. The drive unit is mounted on the frame and connected to the transmission unit. The grading assembly includes a grading roller and a rotating main shaft. The rotating main shaft is located inside the grading roller and extends out of the grading roller, connecting to the transmission unit. The feed hopper is connected to one end of the grading roller, and the other end of the grading roller is connected to the potato vine collecting hopper. The grading roller is composed of multiple stainless steel strips arranged in parallel. The grading roller is divided into a first section, a second section, and a third section. The first section is located near the feed hopper, and the third section is located near the potato vine collecting hopper. The gap between the stainless steel strips in the first section is smaller than the gap between the stainless steel strips in the second section, and the gap between the stainless steel strips in the second section is smaller than the gap between the stainless steel strips in the third section.

[0006] Furthermore, in a preferred embodiment of the present invention, a plurality of rotating blades are provided on the rotating main shaft, the plurality of rotating blades are arranged at equal intervals along the axial direction of the rotating main shaft, and both the rotating main shaft and the plurality of rotating blades are arranged inside the grading roller.

[0007] Furthermore, in a preferred embodiment of this invention, the plurality of rotating blades are helical blades.

[0008] Furthermore, in a preferred embodiment of this utility model, one end of the rotating blade is fixedly connected to the rotating main shaft, and the gap between the other end of the rotating blade and the inner wall of the grading roller is 5-10mm.

[0009] Furthermore, in a preferred embodiment of this utility model, the gap between the stainless steel strips in the first segment is 10-15mm.

[0010] Furthermore, in a preferred embodiment of this utility model, the gap between the stainless steel strips in the second segment is 40-60mm.

[0011] Furthermore, in a preferred embodiment of this utility model, the gap between the stainless steel strips in the third segment is 65-80mm.

[0012] The beneficial effects of the potato impurity removal and grading machine provided by this utility model are as follows: After the potatoes are harvested, they are put into the feeding hopper and enter the grading drum through the feeding hopper. The drive component drives the rotating main shaft to rotate through the transmission component. In the first section, the surface mud and sand of the potatoes can be scattered out of the grading drum through the gaps in the stainless steel strips. As the rotating main shaft rotates, it drives the rotating blades to rotate and transfer the potatoes from the first section to the second section. Some potatoes are scattered out of the grading drum through the gaps in the stainless steel strips in the second section. The remaining potatoes continue to rotate with the rotating main shaft to reach the third section. Some potatoes are scattered out of the grading drum through the gaps in the stainless steel strips in the third section. Finally, the potato vines are collected in the potato vine collection hopper, completing the potato impurity removal and grading. This can solve the problems of incomplete impurity removal, high operating costs, and complex equipment structure in the existing technology. Attached Figure Description
