Weed removing device for tuber crop harvester

Abstract

A grass blocking device for a tuber crop harvester comprises a center shaft, a plurality of weed removing rods arranged on the center shaft at intervals and a limiting device used for limiting the position relation between the weed removing rods and a previous-stage conveying belt of the tuber crop harvester. Each weed removing rod is mounted on the center shaft through a respective rotating sleeve, and the rotating sleeves can rotate relative to the center shaft so as to drive corresponding grass removing rods to independently move around the center shaft; detachable limiting pieces used foraxially limiting the corresponding rotating sleeves are arranged at the positions, close to the two ends of each rotating sleeve, of the center shaft. According to the weed removing device, weeds appearing at each weed removing rod can be removed in time, the problem that a large number of weeds are accumulated to block a potato crop advancing channel is solved, and the distance between every twoadjacent weed removing rods can be adjusted by increasing or decreasing the number of the weed removing rods on the center shaft under the condition that limiting of the limiting pieces to the rotating sleeves is relieved. Finally, the cleanness degree of potato harvesting operation is ensured, and the potato crop harvesting efficiency is improved.

Description

technical field [0001] The invention relates to a potato crop harvester, in particular to a weeding device for the potato crop harvester. Background technique [0002] Potato crop harvesting machines (potato crop digging machine, potato crop picking machine, potato crop excavation, loading, conveying and other joint function machines, etc.) usually put many potato crops Seedlings, weeds, etc. are carried into the transmission device, and finally enter the receiving box or cover the crops after digging. If they are not cleaned up, it will increase the workload of crop harvesting in the later stage, or need to remove seedlings and weeds again. Avoid affecting crop sales. [0003] The solution to this problem in the prior art is usually to manually remove the weeds in time during the harvesting of the tuber crops, or to remove the weeds in the receiving box after the tuber crops are harvested and before they are stored collectively. [0004] No matter what kind of solutions a...

Problems solved by technology

[0004] Regardless of the above solutions, the intensity of manual labor is increased, and the work efficiency is low, and at the same time it is difficult to ensure the weed removal effect

[0005] At present, there are also weeding components for blocking and removing seedlings and weeds during the harvesting of potato crops on the market, but due to their relatively simple structure, although they have a certain weeding and cleaning effect, they have affected the potato crops to a certain extent. The normal harvesting efficiency or cleaning effect cannot meet the needs of users. Therefore, how to automatically and effectively remove seedlings and weeds during the harvesting of potato crops without affecting the harvesting efficiency of potato crops is a challenge for those skilled in the art.
