Description
Technical Field
The invention belongs to agricultural machinery, and mainly relates to an inter-seedling weeding operation part.
Background
In recent years, with the development of organic agriculture in China, the use of various chemical fertilizers, chemical pesticides and chemical herbicides is limited. In order to solve the weeding problem after the chemical herbicide is forbidden, the key point of the scientific and technological work is shifted to the research and development of mechanical weeding machines. The existing weeding machine tool for rice seedlings adopts the vertical rotating weeding structure and mode of the elastic tooth weeding disc, has the defects of complex structure, high manufacturing cost, low weeding efficiency and high seedling hurting rate of rice seedlings, cannot adapt to and meet the requirement of the quality standard of rice seedling weeding, and influences the growth of rice and the improvement of yield.
Disclosure of Invention
The invention aims to solve the problems in the prior art, and researches and designs an inverted V-shaped opposed rice inter-seedling weeding assembly with a new structure by combining the actual requirements of rice inter-seedling weeding operation, so as to achieve the purposes of high weeding efficiency, low seedling injury rate and good operation effect.
The purpose of the invention is realized as follows: a power input shaft is rotatably arranged on the mounting seat, and a driving bevel gear is fixedly arranged on the power input shaft; the left bearing seat and the right bearing seat are symmetrically arranged on the lower side part of the mounting seat in an inverted V shape, a left sleeve and a right sleeve are fixedly mounted on the lower side parts of the left bearing seat and the right bearing seat coaxially and respectively, a left shaft and a right shaft are rotatably inserted and mounted in the left bearing seat, the left sleeve, the right bearing seat and the right sleeve respectively, a left bevel gear and a right bevel gear are fixedly mounted on the upper end parts of the left shaft and the right shaft respectively, and the left bevel gear is meshed with a driving bevel gear and the right bevel gear respectively; and a left conical rigid tooth weeding disc and a right conical rigid tooth weeding disc are fixedly arranged at the lower end parts of the left shaft and the right shaft respectively, so that the inverted V-shaped opposed rice inter-seedling weeding assembly is formed.
The invention adopts the operation mode that the left conical rigid weeding disc and the right conical rigid weeding disc are oppositely arranged and horizontally rotated, greatly improves the weeding operation quality between rice seedlings, and has the characteristics of reasonable and unique structure, high weeding efficiency, low seedling injury rate, good operation effect and strong adaptability.
