Weeding device used in vegetable planting greenhouse

Abstract

The invention discloses a weeding device used in a vegetable planting greenhouse. The weeding device comprises a front frame, a U-shaped frame, an inner rectangular frame and a supporting frame, wherein a weeding mechanism is installed on the U-shaped frame through screws, screw holes are formed in the bottom of the U-shaped frame at intervals, the inner rectangular frame is provided with parallelwheels, motors are arranged in the middles of the parallel wheels, rotary shafts of the motors penetrate through two sides of the inner rectangular frame to be connected with key shafts, the key shafts are movably fixed to the U-shaped frame before the key shafts penetrate through the middle of the U-shaped frame, the bottom of the front frame is fixedly connected with the supporting frame, and an oil tank is arranged in the middle of the supporting frame. The weeding mechanism comprises clamp-connecting parts and turntables, wherein driving wheels are arranged in the clamp-connecting parts,the key shafts are sleeved with the driving wheels, the driving wheels are meshed with driven wheels through gears and are fixedly connected with installing wheels, blades and sweeping strips are uniformly installed on the surfaces of the outer rings of the installing wheels, the blades are installed among the sweeping strips, the single-time weeding efficiency is improved by utilizing adjustableweeding separation distances and a quick and convenient operation way, and meanwhile the weeding device is smaller in size, simple in operation and suitable for a greenhouse operating environment.

Description

technical field [0001] The invention relates to the technical field of weeding in vegetable greenhouses, in particular to a weeding device for 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. In this way, a greenhouse space is formed, and the outer film can well prevent the loss of carbon dioxide produced by the growth of vegetables inside, so that the shed has a good heat preservation effect; [0003] The growth of weeds seriously affects the growth of plants in greenhouses. Weeding is a necessary process. The methods of weeding include chemical drugs, artificial mechanical weeding, etc. Chemical drugs only keep the growth of weeds in the process of weeding. , and weeds canno...

Problems solved by technology

[0003] The growth of weeds seriously affects the growth of plants in greenhouses. Weeding is a necessary process. The methods of weeding include chemical drugs, artificial mechanical weeding, etc. Chemical drugs only keep the growth of weeds in the process of weeding. , cannot remove weeds from greenhouses, and herbicides are likely to remain in the land and be absorbed by vegetables. The traditional mechanical weeding method is too dependent on manpower, and the efficiency of single weeding is poor
