Extirpator capable of using tractor to output power to drive weeding tooth assembly to rotate

Abstract

The invention relates to an extirpator capable of using a tractor to output power to drive a weeding tooth assembly to rotate, and belongs to agricultural machinery. A transmission box is fixedly mounted on a machine frame assembly; a universal transmission shaft and a first chain wheel are mounted on a power input shaft and a power output shaft of the transmission box respectively; a second chain wheel and a third chain wheel are fixedly mounted on a main driving shaft; a fourth chain wheel is fixedly mounted on the weeding tooth assembly; a first chain is arranged on the first chain wheel and the second chain wheel in a sleeved manner; and a second chain is arranged on the third chain wheel and the fourth chain wheel in a sleeved manner. Rotary motion of the weeding tooth assembly of the extirpator is singly driven by power output by the tractor, and is not influenced and controlled by the moving speed of the tractor. The extirpator has the characteristics of simple and reasonable structure, use reliability, high work quality and high production efficiency.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a mechanical cultivating and weeding implement. Background technique [0002] The mechanical cultivator and weeder is commonly known as "blind pull", because it is suitable for the production operation requirements of green food production raw materials, it has begun to be popularized and applied in the weeding operation procedures of agricultural production in recent years. There is no driving force for the rotation of the weeding tooth assembly of the traditional mechanical cultivator weeder, but the weeding tooth assembly generates resistance in contact with the soil when the implement is moving forward, that is, it rotates along with it, and its weeding effect is very poor. In recent years, the machine tool that is driven by the rotation of the ground wheel supported by the cultivator and weeder to drive the rotation of the weeding tooth assembly has been developed, so that the ...

AI Technical Summary

Problems solved by technology

However, since the rotation speed of the supporting ground wheel of the cultivator weeder is limited by the walking speed of the tractor, the rotation speed of the weeding tooth assembly cannot be controlled independently, and the weeding effect still needs to be improved, especially when the tractor travels to the edge of the ground and reduces the speed. , the rotation speed of the ground wheel supported by the implement and the speed of the weeding tooth assembly decrease synchronously, and the quality of weeding and weeding on the side of the field cannot be guaranteed
