Problems solved by technology

However, due to structural design defects, when carrying out the comprehensive weeding operation on the seedlings on the ridge, the rotating weeding toothed disc roller performs rotary tillage operations on the crop seedlings and weeds on the ridge without any selection. Treatment, commonly known as "blind pulling", has a high rate of damage to seedlings

Abstract

The invention discloses a lateral retractable intertillage weeding unit and belongs to agricultural machinery. A power transmission mechanism formed by a driving chain wheel, a driven chain wheel and a chain is installed on a unit plate through a power input shaft and a main driving shaft, an inter-line weeding tooth roller assembly is assembled on the unit plate in a rotary mode through a planet gear shaft, a planet gear, a sun gear and an annular gear, a fixed inner shell is arranged in a roller cavity of the inter-line weeding tooth roller assembly through a planet gear shaft, and a suspension arm frame, a main motor base plate and a base frame are fixedly installed on the fixed inner shell; an inter-plant weeding telescopic boom provided with an inter-plant weeding driving motor, bevel gears A and B, an inter-plant weeding claw assembly and a connecting rod is assembled on the suspension arm frame, a main motor provided with a driving cylindrical gear is installed on the main motor base plate, a driven cylindrical gear, a shaft I, a driving bevel gear, a driven bevel gear, a shaft II and a driving rod are installed on the base frame, and a swing rod is hinged to the connecting rod and the driving rod. By the adoption of the unit, inter-seedling intertillage weeding can be achieved without touching seedlings, and seedling damage rate is low.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a mechanical cultivating and weeding mechanism. Background technique [0002] Mechanical intertillage and weeding tools have a history of decades, commonly known as "blind pulling". With the needs of green organic agricultural production in recent years, the "three reductions" policy requirements to reduce the amount of chemical fertilizers, pesticides, and herbicides, the research and development of mechanical intertillage and weeding tools has become a hot technology that people pay attention to. Especially in Heilongjiang Province, which is the production base of green organic agriculture in my country, the response is more prominent. However, due to structural design defects, when carrying out the comprehensive weeding operation on the seedlings on the ridge, the rotating weeding toothed disc roller performs rotary tillage without any selection on the crop seedlings and weeds o...
