Bionic flexible paddy field inter-row driving type weeding unit

Abstract

The invention discloses a bionic flexible paddy field inter-row driving type weeding unit, and belongs to agricultural machinery. A driving main shaft is installed in the middle of the inner side of a driving box shell, driving bevel gears are symmetrically and fixedly installed on the left end portion and the right end portion of the driving main shaft respectively, driving half shafts are symmetrically installed on the left side portion and the right side portion of the driving box shell and located outside the two ends of the driving main shaft respectively, driven bevel gears are fixedly installed on the driving half shafts, the driven bevel gears are meshed with the driving bevel gears, and a bionic flexible weeding wheel consisting of a radial plate, a rod seat, web plate opening degree adjusting left and right torsion springs, left and right pin shafts, web plate right, middle and left support rods, an elastic web plate, a web plate return pin shaft, a web plate return torsion spring, a limiting pin, a bolt, left, middle and right support rod shafts and a cylindrical seat is fixedly arranged on the outer end part of each driving half shaft. The unit can thoroughly remove paddy field soil adhered to the elastic web plates, and has the characteristics of good weeding effect, high operation efficiency and low power consumption.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a weeding assembly suitable for mechanical weeding between paddy fields. Background technique [0002] With the increasing demand of Chinese people for green organic rice, it has become a development trend to use less or ban chemical herbicides in rice fields. Instead, mechanical weeding machines have been used in inter-row weeding operations in paddy fields, providing technical support for green and organic rice production. At present, paddy field inter-row weeding wheels are mostly used as weeding work parts on paddy field inter-row weeding implements. During the operation, the weeding wheel between the rows of the paddy field extends into the soil of the paddy field by gravity, and when the machine is moving forward, it is passively rotated by the resistance of the muddy water in the paddy field to cut off the root system of the weeds in the row of the paddy field or pick them o...

Problems solved by technology

During the operation, the weeding wheel between the rows of the paddy field extends into the soil of the paddy field by gravity, and when the machine is moving forward, it is passively rotated by the resistance of the muddy water in the paddy field to cut off the root system of the weeds in the row of the paddy field or pick them out from the soil layer come out to make weeds float on the water surface and die, and complete weeding between rows of paddy fields. However, because the existing weeding wheels between rows of paddy fields are all rigid integral structures connected by metal weeding blade teeth and weeding wheel discs, it is easy to stick during weeding. soil, and slipping occurs, which not only increases the traction force of the operation, but also has low weeding efficiency and poor weeding quality, which cannot meet the technical requirements for inter-row weeding in paddy fields
