Hand-pushed narrow sprayer

Abstract

The invention discloses a hand-pushed narrow sprayer obtained by improving an agricultural sprayer and belongs to the technical field of farm machinery. The hand-pushed narrow sprayer structurally comprises a dosing system, a cart, a telescopic sliding rod, a telescopic loop bar, a supporting wheel carrier, an electric wheel carrier, a hand-pushed bracket or base-plate-free hand-pushed bracket anda spray head. Trundles are arranged at the lower portion of the hand-pushed bracket, or a pesticide tank is placed on the cart, and the spray head comprises a vertical double-sided multi-spray-nozzlespray head, a vertical double-inclined-pipe multi-spray-nozzle spray head, a horizontal downward multi-spray-nozzle spray head and a swing spray head. An operator enters ridges or passages to push the hand-pushed bracket during spraying operation, a dosing water pump and a motor are started up or shut down, the spray heads spray large-area pesticide liquid towards the left side and the right side, the labor intensity is low, the efficiency is high, the front-back length of the hand-pushed bracket is larger, the left-right length is smaller, gaps among the ridges are convenient to pass, and operation is very convenient and saves much time.

Description

technical field [0001] The invention relates to a sprayer for spraying pesticides, belonging to the technical field of agricultural machinery, in particular to a hand-push narrow-body sprayer. Background technique [0002] At present, two kinds of knapsack hand-operated sprayers and knapsack-type electric sprayers are widely used in field crops and vegetable planting production: when using knapsack-type hand-operated sprayers, the sprayer medicine box is carried on the back, and the pressure lever is pressed up and down to a certain level with the left hand. When the pressure is high, hold the handle of the spray bar with your right hand to turn on the switch and swing the spray bar. The liquid medicine passes through the outlet pipe and then through the spray bar, and finally the liquid medicine is sprayed out by the nozzle; The lower part of the medicine box is connected to a small electric pump. The small electric pump is connected to the water outlet pipe, the spray rod,...

AI Technical Summary

Problems solved by technology

[0004] The medicine box of the sprayer is carried on the back, and it weighs 15 kg to 20 kg when it is filled with liquid medicine. During the spraying operation, it is necessary to swing the spray boom continuously, which is very labor-intensive. Farmers are sweating profusely when spraying the medicine, which is very hard.

[0005] 2. Long working hours:

[0006] Spraying an acre of crops often requires two or three barrels of liquid medicine, especially for cucumbers, cantaloupe and other crops that require melon racks or hanging ropes, it takes 30 to 50 minutes, the operation time is long and the efficiency is very low

[0007] 3. Inconvenient operation:

[0008] When spraying the liquid medicine in the vegetable greenhouse, since the field ridges in the vegetable greenhouse are small, if you are planting cucumbers, cantaloupe, etc., you need to set up melon racks or hanging ropes. When spraying, people have to enter the field ridges, and the space is small. Holding the spray rod in front of you, and carrying a heavy medicine box behind you, after spraying, you have to turn around and return carefully along the original route, so as not to damage or step on the vegetables, which is time-consuming and laborious, and the operation is very inconvenient
