AI Technical Summary

Technical Problem

The existing potato crop harvester grading device has weak function in adjusting the grading spacing, and it has insufficient function in preventing damage to potatoes, which leads to the easy damage to potatoes during collection.

Method used

A grading component including a servo motor, connecting rod, supporting frame, grading rod, spring and card block is designed. The servo motor drives the connecting rod to rotate and drive the support frame to shake. The operator can adjust the position of the grading rod as needed to achieve flexible grading. At the same time, through the setting of slide rails and buffering, damage to potatoes during the drop process is reduced.

Benefits of technology

The flexible adjustment of the grading device is realized to adapt to the grading size of different needs, avoiding the problem of difficult adjustment of the middle spacing of the traditional device; at the same time, the damage of potatoes is reduced through the buffer device and the quality of the collected product is improved.

Abstract

The utility model relates to the technical field of agricultural machinery, in particular to a grading device of a tuber crop harvester, which comprises a machine body, a fixing plate is fixedly connected to the middle of one side of the machine body, and a grading component is fixedly connected to the top of the fixing plate. Through the arrangement of the servo motor, the connecting rod, the supporting frame, the grading rod, the spring and the clamping block, when the grading device is used, the connecting rod is driven to rotate back and forth through the operation of the servo motor, the supporting frame is driven to shake through the rotation of the connecting rod, and an operator can clamp the grading rod at different positions of the inner wall of the supporting frame according to requirements; and when the grading rods are clamped into the supporting frames, clamping blocks can be clamped into groove holes due to the tension of springs, so that the grading rods are fixed, the effect of adapting to different requirements is achieved, and the problems that due to different requirements, the grading sizes of the potatoes are different, the middle distance of a traditional grading device is difficult to adjust according to the requirements, and the grading size of the potatoes is not uniform are solved. And therefore, the device has limitation and is not convenient to use.
