Seedling avoiding weeding device for intertillage stage corn field

Abstract

The invention belongs to the technical field of agricultural machines, and relates to a seedling avoiding weeding device for an intertillage stage corn field. The seedling avoiding weeding device is composed of a driving device, a connecting rod assembly and a weeding component, wherein the driving device is provided with a stepping motor and a travel switch with a flexible shaft; three weeding comb assemblies in the weeding component are identical in structure, each strip-shaped plate is fixedly connected with a comb tooth plate, and two rows of comb teeth are fixedly and symmetrically connected to the two sides of the longitudinal axis of the lower surface of each comb tooth plate; an expansion sleeve I of the connecting rod assembly is fixedly connected with an output shaft of the stepping motor in the driving device, the three weeding comb assemblies in the weeding component are fixedly connected to the upper face of a disc in the connecting rod assembly, and the included angle of120 degrees is formed between the three weeding comb assemblies. The seedling avoiding weeding device is used in the growth intertillage stage of corn crops and is capable of automatically avoiding corn plants and removing weeds between rows and plants, simple in structure, low in cost and high in practicability.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a device for avoiding seedlings and weeding in a corn field during inter-cultivation period. Background technique [0002] During the growth of corn, it is always accompanied by the growth of weeds. Under the same space and conditions, corn and weeds compete with each other. In order to ensure a good growth environment for corn, it is necessary to grow corn plants. Weeding at different times. At present, the removal of corn weeds mainly depends on manual weeding and chemical weeding. Manual weeding has high labor intensity and low efficiency, and chemical weeding pollutes the environment and harms the human body. [0003] In terms of inter-plant weeding, compared with the existing technical literature, such as the invention patent "CN 102972111 B" authorized patent number "a weeding device capable of removing weeds between seedlings in the row", it is necessary ...

AI Technical Summary

Problems solved by technology

At present, the removal methods of corn weeds mainly rely on manual weeding and chemical weeding. Manual weeding is labor-intensive and low in efficiency. Chemical weeding pollutes the environment and harms the human body.

[0003] In terms of inter-plant weeding, compared with the existing technical literature, such as the invention patent "CN 102972111 B" authorized patent number "a weeding device capable of removing weeds between seedlings in the row", it is necessary to frequently control the forward and reverse of the motor, And targeted weeding methods, for some small weed seedlings cannot be removed in advance, the operation efficiency is not high

In the invention patent "Intelligent Row-to-Row Weeding Device for Crop Seedling Stage" with the authorized patent number "CN103314663 BL", when the L-shaped weeding knife enters the soil, it depends on the expansion and contraction of the second main axis to switch between inter-row and inter-row weeding In the state, the resistance is relatively large, and the working efficiency is not high
