Height-variable large-area weeding equipment for agricultural vegetable greenhouse

Abstract

The invention discloses height-variable large-area weeding equipment for an agricultural vegetable greenhouse. The height-variable large-area weeding equipment comprises a U-shaped mounting plate, androller mounting grooves are formed in the lower ends of two vertical plates of the U-shaped mounting plate. A plurality of rollers are mounted in the roller mounting grooves. A hydraulic cylinder isfixedly mounted in a rectangular hole, the lower ends of rotary sleeves are connected with conical rotary discs, and a plurality of cutting stationary knives are arranged on the outer sides of the conical rotary discs. According to the weeding equipment, a driving gear of a driving motor drives four driven gears to rotate, the four conical rotary discs and the cutting stationary knives can be driven to rotate, large-area weeding work can be carried out, the weeding speed is increased, the weeding efficiency is high, and time and manpower are saved. According to the weeding equipment, by arranging the hydraulic cylinder, the hydraulic cylinder can drive a rectangular pressing plate to ascend and descend, and the height of a cutting knife set can be adjusted according to geomorphic needs during weeding, so that weeding is more convenient and cleaner, and the effect is better.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a height-variable large-area weeding device for agricultural vegetable greenhouses. Background technique [0002] The vegetable greenhouse is a frame-covered structure with excellent thermal insulation performance. It appears that people can eat off-season vegetables. Generally, the vegetable greenhouse uses a bamboo or steel structure frame, covered with one or more layers of thermal insulation plastic film. , thus forming a greenhouse space. The outer film can prevent the loss of carbon dioxide produced by the growth of vegetables inside, so that the shed has a good heat preservation effect. The vegetable greenhouse needs to weed the land before planting vegetables, but the traditional weeding equipment generally has the following defects: most The weeding machine can only weed a small area, resulting in slow weeding speed and low weeding efficiency; most weeding machine...

AI Technical Summary

Problems solved by technology

The outer film can prevent the loss of carbon dioxide produced by the growth of vegetables inside, so that the shed has a good heat preservation effect. The vegetable greenhouse needs to weed the land before planting vegetables, but the traditional weeding equipment generally has the following defects: most The weeding machine can only weed a small area, resulting in slow weeding speed and low weeding efficiency; most weeding machines cannot adjust the height of the cutting knife group according to the terrain, which makes the weeding work more inconvenient and prone to weeding Unclean phenomenon; therefore, we propose a height-variable large-area weeding equipment for agricultural vegetable greenhouses
