A kind of conveying roller for sweet potato roller sorting machine

Abstract

The present invention discloses a transmission roller for a sweet potato roller sorter, which discloses that the inner transmission roller intermittently pushes the outer transmission roller to rotate by means of a push assembly, and when the outer transmission roller is in a free state, it can cooperate with the reversal of the sweet potato to avoid wear and tear on the sweet potato The transmission roller is characterized in that the inner transmission roller is placed on the rotating shaft, the outer transmission roller is placed on the inner transmission roller, there is eccentricity between the inner transmission roller and the outer transmission roller, and the inner transmission roller The outer transmission roller is intermittently pushed by the push assembly, and the feature is that the inner transmission roller is intermittently driven to rotate by the push assembly, and the outer transmission roller can cooperate with sweet potatoes to reverse in a free state.

Description

technical field [0001] The invention discloses a transmission roller for a sweet potato roller sorter, relating to a sorting transmission roller used in a roller sweet potato sorter, and belongs to the field of agricultural machinery. In particular, it relates to a transmission roller that makes the inner transmission roller intermittently push the outer transmission roller to rotate through the push assembly, and when the outer transmission roller is in a free state, it can cooperate with the sweet potato to reverse and avoid the transmission roller from causing wear to the sweet potato. Background technique [0002] Sweet potato is one of the important tuber crops in China. In order to promote the good development of the sweet potato industry and make sweet potato products widely compatible with national and even global products, a standard sweet potato grading system has been formulated. At present, the existing sweet potato grading equipment mainly The grading and screen...

[0002] Sweet potato is one of the important tuber crops in my country. In order to promote the good development of the sweet potato industry and make sweet potato products widely compatible with national and even global products, a standard sweet potato grading system has been formulated. At present, the existing sweet potato grading equipment mainly The grading and screening of conveying rollers is carried out by using different spacing changes between the conveying rollers to sort according to the size of sweet potatoes, but when sweet potatoes are driven between adjacent rollers, the adjacent rollers rotate at the same time and the direction of rotation is the same. As long as the sweet potato goes down one end, there will be a hard collision or hard rotation extrusion between the rotating conveying roller, which will cause damage to the sweet potato skin and affect the sorting quality of the sweet potato.

[0003] Notification number CN208679701U discloses a kind of sweet potato sorting machine, is characterized in that it comprises climbing hoist, dregs filtering device, small potato sorting device, middle potato sorting device and big potato sorting device, small potato sorting device , The distance between a group of transmission rollers of the medium potato sorting device and the large potato sorting device gradually increases, the inlet of the dregs filtering device is connected with the outlet of the climbing elevator, and the outlet of the dregs filtering device is connected with the small potato sorting device. The inlet of the device is connected, the outlet of the small potato sorting device is connected with the inlet of the medium potato sorting device, and the outlet of the medium potato sorting device is connected with the inlet of the large potato sorting device. The constantly rotating transmission rollers are prone to hard rotation and hard collision with sweet potatoes, causing damage to the sweet potato skin and affecting the quality of sweet potato sorting
