AI Technical Summary

Technical Problem

When using existing pesticide spraying devices to weed after corn seedling emergence, pesticides are easily trapped by corn leaves, resulting in uneven spraying and affecting the weeding effect.

Method used

An intelligent pesticide spraying device was designed, comprising a remote-controlled vehicle body, a support base, a linkage mechanism, a main cutting component, a spraying mechanism, and a secondary cutting component. The spacing of the cutting components is adjusted by regulating the motor and the bidirectional threaded rod. Combined with the swing component and spray bar of the spraying mechanism, uniform spraying of pesticide liquid is achieved.

Benefits of technology

It achieves uniformity of pesticide spraying between corn clumps and comprehensive weed control, thus improving weed control effectiveness.

Abstract

This utility model relates to the field of pesticide spraying technology, and more particularly to an intelligent pesticide spraying device for ground weed control in cornfields. It includes a remote-controlled vehicle body and a support base welded to the vehicle body. A bidirectional threaded rod is rotatably mounted on the support base, and an adjusting motor is also mounted on the support base. The output shaft of the adjusting motor is connected to the bidirectional threaded rod via a belt drive. It also includes a linkage mechanism movably mounted on the bidirectional threaded rod. The linkage mechanism includes a first connecting seat, a first connecting rod, a second connecting seat, a second connecting rod, and a third connecting seat. A main cutting component is mounted on the first connecting seat, and secondary cutting components are mounted on the two second connecting seats. A spraying mechanism is mounted on the remote-controlled vehicle body, including a pesticide tank, a miniature water pump, and a spray boom. A swinging component that drives the spray boom to swing is mounted on the second connecting rod. This utility model's pesticide spraying device has the advantages of comprehensive pesticide spraying and good weed control effect.
