Qilong dryland low stalk crop sprayer

Abstract

The invention discloses a sprayer for low-stalk crops in dry land, which comprises a medicine box and a water suction pipe arranged in the medicine box. The water suction pipe seals and passes through the medicine box, and a spray rod is connected at the outlet end. The free end of the spray rod is connected to the spray head; a cart; a linkage assembly, which includes: a cam transmission assembly; a horizontal transmission assembly; a vertical transmission assembly, which includes a vertical rod, and the upper part of the vertical rod is sleeved with a sliding sleeve rod. The sliding sleeve rod is slidably and fixedly arranged relative to the vertical rod, and a second bevel gear is coaxially fixed on the outer circumference of the sliding sleeve rod located in the gearbox, and the central axis of the vertical rod intersects the central axis of one of the wheel shafts perpendicularly The third bevel gear is fixed coaxially on the wheel shaft, and the fourth bevel gear meshed with the third bevel gear is fixed on the vertical bar. The invention has the beneficial effects of uniform spraying, reducing the size difference of sprayed droplets and improving spraying effect.

Description

technical field [0001] The present invention relates to the field of nebulizer devices. More specifically, the present invention relates to a sprayer for low stalk crops in dry land. Background technique [0002] my country is a large agricultural production country. The prevention and control of agricultural diseases and insect pests mainly depends on chemical control. There are many types of pesticide application equipment, including motorized sprayers, electric sprayers, high-pressure automatic sprayers, and ordinary hand-operated sprayers. For most small-scale agricultural retail farmers The vast majority of spraying equipment is still a knapsack-type ordinary manual sprayer represented by the "Gongnong-16" from the 1950s to the 1970s. This sprayer consists of a cylinder, a hand-pumped air pump and a spray gun. It has the following problems: [0003] First, because the operator directly relies on the operator's arm to shake the operating handle up and down to pressurize ...

AI Technical Summary

Problems solved by technology

[0003] First, because the operator directly relies on the operator's arm to shake the operating handle up and down to pressurize and spray the liquid medicine, the operator is very prone to fatigue, resulting in uneven pressure during the spraying period, and large differences in the sprayed droplet size, which directly affects the spray effect and reduces the spraying effect. Improve the utilization rate of pesticides and the effect of controlling diseases and insect pests;

[0004] Second, the knapsack manual sprayer sprays with the other hand during the spraying process, and adjusting the angle brings inconvenience to a certain extent for uniform spraying;

[0005] Third, it needs to be carried manually, and at the same time increases the fatigue of the operator
