Method and device for judging wear condition of harvester hob

Abstract

The invention discloses a method and a device for judging the wear condition of a hob of a harvester, and relates to the field of agricultural machinery. The method includes: obtaining the torque of the chopping roller of the harvester and the humidity of the chopped harvest at intervals of a preset time; judging the variation trend of the torque and the variation trend of the humidity; according to the variation trend of the torque and the variation trend of the humidity Determine the wear on the harvester reels. The method and device for judging the wear of the hob of the harvester provided by the present invention can not only effectively avoid the impact of the wear of the hob on the packing compaction degree and final fermentation degree of the harvest, but also improve the operating efficiency of the harvesting operation, Compared with the method of manual judgment, it can accurately judge whether the hob has been worn, and has the advantages of high judgment accuracy and high practicability.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a method and a device for judging the wear condition of a hob of a harvester. Background technique [0002] At present, harvesters are usually used to harvest crops, and the stalk chopping device of the harvester mostly uses a chopping hob, and the specific working environment causes the blade of the chopping hob to wear to varying degrees after working for a certain period of time, resulting in cutting Poor crushing quality, continuous cutting, kneading and other problems. At this time, it is necessary to know the wear and tear of the chopping hob in time, so as to sharpen the knife in time, otherwise it will not only affect the packing compaction degree, and then affect the final fermentation degree, but also affect the operating efficiency of the harvesting operation. [0003] At present, the wear degree of the hob is usually judged according to the experience of the dri...

AI Technical Summary

Problems solved by technology

[0002] At present, harvesters are usually used to harvest crops, and the stalk chopping device of the harvester mostly uses a chopping hob, and the specific working environment causes the blade of the chopping hob to wear to varying degrees after working for a certain period of time, resulting in cutting Poor crushing quality, continuous cutting, kneading and other problems

At this time, it is necessary to keep abreast of the wear of the chopping hob in order to sharpen the knife in time, otherwise it will not only affect the packing compaction degree, and then affect the final fermentation degree, but also affect the working efficiency of harvesting operations

[0003] At present, the wear degree of the hob is usually judged according to the experience of the driver. However, various factors such as crop varieties, maturity, and harvesting environment across fields will affect the wear speed of the shredding hob, so the driver cannot timely Accurately judge the wear degree of the hob
