Description

technical field

[0001] The invention belongs to agricultural machinery, and mainly relates to a telescopic teeth roller type weeding and loosening operation unit equipped on a mechanical weeding and loosening machine tool. Background technique

[0002] In order to produce more and better green organic agricultural products and protect human health, in recent years, in the process of agricultural production in our country, we have begun to advocate and promote the "three reductions" agronomic technical requirements, that is, reducing chemical fertilizers, reducing pesticides, and reducing weeding dosage of the agent. Therefore, the use of mechanical weeding and soil loosening operations for row crops has entered the stage of wider application. However, due to structural defects, whether it is the traditional follow-up mechanical weeding and loosening roller, or the mechanical weeding and loosening roller driven by the power of the ground wheel of the implement or the output ...
