Dynamic weeding device

Abstract

The invention discloses a dynamic weeding device which comprises a bracket, a driving device, a plate body, a hoeing rod and a hoeing cutter, wherein a horizontal handrail is arranged in the upper part of the bracket, a horizontal fixed rod is arranged in the middle part of the bracket, a second end of the bracket is connected with a driven wheel, and a bump is arranged on the surface of the driven wheel; the driving device comprises a driving wheel, wherein a driving axle is arranged in the middle of the driving wheel, and a belt pulley is arranged at the second end of the driving axle in a sleeving manner; the surface at one side of the plate body is connected with a supporting column while an arc-shaped chute is formed on the surface at the other side of the plate body, and a slide block is arranged in the arc-shaped chute; a compression spring is connected between the hoeing rod and a crank; a strip-like through hole is formed on the second side face, toward the ground, of the hoeing cutter, sponge is paved on the second side face, and the hoeing cutter communicates with the hoeing rod to form a liquid medicine circulating path. The dynamic weeding device disclosed by the invention has the advantages of being simple in structure and economical and practical.

Description

technical field [0001] The invention relates to an agricultural tool. More specifically, the present invention relates to a powered weed control device. Background technique [0002] In addition to the crops consciously cultivated by farmers, there are many unwanted weeds in the crop fields. The weeds in the farmland have many hazards: competing for the nutrients, water and sunlight needed by the crops; hindering the ventilation and light transmission of the field; Promoted the occurrence of pests and diseases. Weeds directly or indirectly affect agricultural production, seriously affecting the yield, quality and quality of crops. [0003] At present, the control of weeds in farmland usually adopts manual weeding, mechanical weeding, biological control and chemical weeding. Wherein artificial weeding labor intensity is big, and work efficiency is low. Mechanical weeding improves the weeding efficiency. Generally, there are two methods: cutting the grass roots and digging...

Problems solved by technology

Among them, manual weeding is labor-intensive and low in work efficiency

Mechanical weeding improves the weeding efficiency. Generally, there are two methods: cutting the grass roots and digging them into the soil. However, both methods have disadvantages: the first method cuts the grass roots, because the roots of the weeds are still under the surface In the soil, weeds will re-grow after a suitable climate, which increases the weeding work again; the second is to dig out the grass roots, and to dig out the weed roots in the land, weeding tools must be inserted under the ground surface, so that although it is thoroughly Removes weeds, but severely disrupts the topsoil hierarchy, resulting in greater water loss from the soil

And mechanical weeding method needs to consume energy, the cost is higher

Chemical weeding is relatively time-saving and labor-saving. At present, manual sprayers or motorized weeds are usually applied to the weeds in the farmland. The disadvantages of these methods are that the herbicide application area is large and the dosage is large, which will cause the pesticide residues in agricultural products to exceed the standard. while seriously polluting the environment
