A seedling weeder equipped on a mechanical cultivator weeder

Abstract

The invention provides an inter-seedling weed remover assembled on a mechanical trash cultivator and belongs to agricultural machinery. A telescopic push-pull rod is assembled in a cantilever type fixed sleeve; a transmission case shell is mounted on the outer end part of the telescopic push-pull rod in a mode that a vertical inclination angle can be adjusted; a motor A, a cylindrical gear and a rack are respectively assembled on the transmission case shell; the cylindrical gear is fixedly arranged on the motor shaft of the motor A; the cylindrical gear is meshed with the rack; a mounting baseprovided with a motor B and a toothed disc assembly is fixedly arranged on the rack; the motor shaft of the motor B is connected with the toothed disc assembly; a plurality of tooth holders are assembled on the toothed disc assembly; and inter-seedling weed removing and soil loosening teeth are mounted on the tooth holders. The inter-seedling weed remover completes weed removing and soil loosening operations for inter-seedling parts of crops by adopting an avoiding mode under the condition of not touching crop seedlings, and meets fine cultivation requirements; and the inter-seedling weed remover has the characteristics of novel and reasonable structure, low seedling damage rate, reliable use, good work synchronicity, smooth operation and high adaptability.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a mechanical weeding operation assembly. Background technique [0002] In recent years, with the national proposal and implementation of the "three reductions" policy for reducing the use of chemical fertilizers, pesticides, and herbicides, the enhancement of human awareness of environmental protection, and the increase in demand for green and organic agricultural products, mechanical intertillage and weeding has a good It is highly valued for its environmental protection, non-toxicity and economy. At present, the difficulty of mechanical weeding is to remove the weeds between crop seedlings, and the technical key to weeding between crop seedlings is how to make the weeding parts avoid the crop seedlings. Due to structural design problems of traditional and current mechanical weeding machines, the intertillage and weeding parts cannot avoid crop seedlings during operation, commonly...

AI Technical Summary

Problems solved by technology

Due to structural design problems of traditional and current mechanical weeding machines, the intertillage and weeding parts cannot avoid crop seedlings during operation, commonly known as "blind pulling", resulting in a high rate of damage to seedlings and high randomness of this type of machine tool, which is difficult to meet the needs of modern precision agriculture.
