Small handheld weeding device in greenhouse

Abstract

The invention relates to a small handheld weeding device in a greenhouse and belongs to the field of agricultural machinery. The device comprises a handle, a driving device handle, a driving chain wheel, a transfer chain wheel, two supporting rods, a steering bevel gear, a driving bevel gear and a weeding tool. A weeding tool for weeding is mounted on the driving bevel gear for removing weeds in the greenhouse; the driving chain wheel and the driving handle are mounted at one end of the supporting rod; the steering bevel gear and the transmission chain wheel are mounted on one end of the supporting rod while the other is connected to the other supporting rod through a bolt fastening piece; one end of the driving bevel gear is connected to the weeding tool while the other end is engaged to the steering bevel gear. The two supporting rods connected through the bolt can stretch and retract, and different lengths can be adjusted by replacing chains in different specifications, so that weeding operations of crowds with different heights are facilitated.

Description

[0001] Technical field [0002] The invention relates to a small hand-held weeding device inside a greenhouse and belongs to the field of agricultural machinery. Background technique [0003] At present, most of the internal weeding in greenhouses in my country adopts large-scale plowing, sowing and spraying pesticides, etc. The existing mechanical devices cannot efficiently remove some small areas and a few weeds, and are large in size and poor in operability, which is not conducive to Working in some small spaces lacks flexibility, which makes weeding take a long time, is not targeted, and wastes a lot of energy. Therefore, there is a need for a weeding tool that can effectively remove a small number of weeds and is convenient for hand-held operation, which has great significance for the practical application of the device. To sum up, reasonable, targeted and convenient weeding tools have the following characteristics: (1) The device is highly portable; (2) The device uses m...
