Roller type weeding and soil loosening operation unit provided with retractable teeth

Abstract

The invention discloses a roller type weeding and soil loosening operation unit provided with retractable teeth, and belongs to agricultural machinery. A left end cover and a right end cover are fixedly mounted at the left end and the right end of a roller respectively, a supporting crank throw shaft is assembled in the center of the left end cover, the left side part of the supporting crank throw shaft is fixedly mounted on a positioning and supporting seat, a driving shaft is fixed in the center of the right end cover and inserted in a bearing block assembly, and a crankshaft is mounted in a central hole of the driving shaft; a retractable tooth shaft is fixedly mounted on the inner side wall surface, opposite to the crankshaft, of the crank throw shaft, located at the inner part of a cavity of the roller and sleeved with a plurality of retractable teeth, and rack parts of the plurality of retractable teeth penetrate through the side wall of the roller respectively. The roller type weeding and soil loosening operation unit solves the technical problem of winding by straw, stubble and weeds during weeding and soil loosening operation, is novel and reasonable in structure, good in operation quality, high in efficiency and wide in application range, and has few faults.

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 ...

AI Technical Summary

Problems solved by technology

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 power of the tractor, it is easy to cause the mechanical weeding and loosening of the soil during the mechanical weeding and loosening operation. Residual straw, root stubble and weeds on the land surface are entangled on the mechanical weeding and loosening roller, causing blockage, which not only increases the injury rate of seedlings, reduces the effect of weeding and loosening the soil, but also reduces the operating efficiency of the machine tool and increases the amount of cleaning work , labor-intensive

Especially in the case of poor land surface cleanliness, the above problems are more obvious, prominent and serious
