An electric weeder

Abstract

The invention discloses an electric weed pull-up machine which comprises a machine frame, a weed separating device, a plurality of weed pull-up devices, a driving wheel and a controller. The machine frame is provided with a plurality of weed pull-up cavities, weed outlets corresponding to the weed pull-up cavities and guide-out plates arranged at the weed outlets; the weed separating device is arranged at the front end of the machine frame, the weed pull-up devices are provided with left weed pull-up screws and right weed pull-up screws, the left weed pull-up screws and the right weed pull-upscrews are rotationally arranged on the machine frame, the upper portions of the left weed pull-up screws and the upper portions of the right weed pull-up screws are located inside the weed pull-up cavities, first spiral teeth are arranged on the peripheries of the left weed pull-up screws, and second spiral teeth are arranged on the peripheries of the right weed pull-up screws; the driving wheelis arranged at the rear end of the machine frame, and the controller controls the driving wheel, the left weed pull-up screws and the right weed pull-up screws to operate. By adopting the structure, the electric weed pull-up machine can effectively remove weed and can greatly lower manpower.

Description

technical field [0001] The invention relates to an electric tool for removing weeds, in particular to an electric weeder. Background technique [0002] Weeds refer to plants that grow in places that are harmful to human survival and activities, and are generally non-cultivated wild plants or plants that have no effect on humans. According to the needs of chemical control, it can be divided into grasses, sedges and broad-leaved grasses. In addition, weeds can also be classified according to their nutritional type, growth habit and reproduction mode. Its biological characteristics are as follows: multiple modes of propagation, strong reproduction and regeneration, generally shorter life cycle than crops, mature seeds fall as they mature, strong resistance to stress, and high photosynthetic efficiency. The main hazards of weeds in farmland are: competing with crops for nutrients, water, sunlight and space, hindering field ventilation and light transmission, thereby reducing c...

AI Technical Summary

Problems solved by technology

The main hazards of weeds in farmland are: competing with crops for nutrients, water, sunlight and space, hindering field ventilation and light transmission, thereby reducing crop yield and quality; many weeds are intermediate hosts or boarding places for pathogenic microorganisms and pests, cause disease and pests

In addition, the seeds or pollen of some weeds contain toxins, which can poison humans and animals.

[0003] The removal of weeds is very necessary for human beings. In the prior art, people mostly use hand-pulling, hoeing or spraying with drugs for weed removal. The former two waste the physical strength of the operator, and the latter will hurt crops or vegetation

Although there is already a hand-held electric weeder in the existing market, which seems to save manpower, but in the process of using this hand-held electric weeder, the operator needs to bend down all the time to operate, and bend over for a long time. The waist will make the operator's waist feel uncomfortable, and may also cause strain on the soft tissue of the neck, back, and waist muscles. Moreover, when this weeder removes weeds in different directions, manual operations are required, especially for crop rows. When removing weeds in a large area, the existing hand-pull, hoe-type and hand-held electric weeders are not suitable for this large-area operation, which is time-consuming and laborious, and cannot meet the requirements of rapid weeding
