Inverted-V-shaped opposite type rice inter-seedling weeding assembly

Abstract

The invention discloses an inverted-V-shaped opposite type rice inter-seedling weeding assembly, belonging to agricultural machinery. A power input shaft is mounted on a mounting base; a driving bevelgear is fixedly arranged on the power input shaft; a left bearing seat and a right bearing seat are symmetrically arranged at the lower part of the mounting seat in an inverted V shape; a left sleevedrum and a right sleeve drum are coaxially and fixedly arranged on the lower side parts of the left bearing seat and the right bearing seat respectively; a left shaft and a right shaft are rotatablymounted in the left bearing seat, the left sleeve drum, the right bearing seat and the right sleeve drum respectively; a left bevel gear, a left conical rigid tooth weeding disc and a right bevel gearare fixedly mounted at the upper end and the lower end of the left shaft and the lower end of the right shaft respectively; and the right conical rigid tooth weeding disc and the left bevel gear aremeshed with the driving bevel gear and the right bevel gear respectively. The assembly is reasonable and unique in structure, high in weeding efficiency, low in seedling damage rate, good in operationeffect and high in adaptability.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to the weeding operation parts between seedlings. Background technique [0002] In recent years, with the development of organic agriculture in my country, the use of various chemical fertilizers, chemical pesticides and chemical herbicides has been restricted. In order to solve the problem of weeding after chemical herbicides are banned, the focus of scientific and technological work has shifted to the research and development of mechanical weeding tools. The weeding structure and method of the vertical rotation of the spring-toothed weeding disc that is currently used on the rice seedling weeding machine not only has a complex structure and high manufacturing cost, especially the low weeding efficiency of the rice seedlings and the high rate of injury, which cannot be adapted and satisfied. The quality standard requirements for weeding between rice seedlings affect the growth and yi...
