Abstract

The utility model relates to an agricultural machine, particularly a knapsack manual spraying device. The utility model mainly comprises a medicine box, a pump barrel, an air chamber, a spraying component, and a rocker handle, wherein, the pump barrel is communicated with the air chamber through a water outlet pipe, the starting part of the water outlet pipe of the pump barrel is upwards inclined, and a slope angle is formed between the starting part of the water outlet pipe of the pump barrel and the pump barrel. The utility model has the advantages of low inflating frequency, physical strength saving, increased work efficiency, high speed for liquid discharge, far range, etc. and has the advantage that a spray head is not easily clogged when low volume medicine is sprayed.

Description

Knapsack hand sprayer

The utility model relates to a kind of agricultural machinery, specifically a kind of backpack hand spray device.

In the prior art, knapsack hand sprayer is a kind of equipment for plant protection that generally use in present China rural area, it mainly is made up of spray tank, pump barrel, air chamber, spraying parts and rocker lever etc., pump barrel is the reciprocating piston force pump, carry out work with handle, the beginning part of the outlet pipe of pump barrel is vertical with pump barrel, the inlet of air chamber and liquid outlet are positioned at the same end of air chamber, its weak point is:＜1〉inflate the frequency requirement height, generally, cause operator's fatigue easily at 25-30 time/minute;＜2〉when low capacity spray medicine, shower nozzle easily stops up, and influences work efficiency;＜3〉fluid speed is slow;＜4〉range is short, is not suitable for tall and big trees and uses.

The purpose of this utility model is to avoid above-mentioned defective and a kind of knapsack hand sprayer that frequency is low, be difficult for obstruction, fluid speed height, far firing range of inflating is provided.

To achieve these goals, the utility model provides a kind of technical solution: this spray tank, pump barrel, air chamber, spraying parts and the rocker lever of mainly comprising, pump barrel leads to air chamber through outlet pipe, it is acclivitous that the outlet pipe of pump barrel begins part, and forms the inclination angle between the pump barrel.

For reaching better effect, at the two ends of described air chamber inlet and liquid outlet are set respectively, inlet communicates with the outlet pipe of pump barrel, and liquid outlet communicates with the spraying parts.

Of the present utility model have a following advantage: the frequency of inflating is low, saves muscle power, improves work efficiency; Shower nozzle is difficult for stopping up when low capacity spray medicine, and fluid speed is fast, and far firing range is applied widely.

It among Fig. 1 structural representation of the present utility model.

Below in conjunction with accompanying drawing and concrete embodiment essentiality content of the present utility model is described in further detail.

This knapsack hand sprayer is made up of spray tank (1), pump barrel (2), air chamber (3), spraying parts (4) and rocker lever (5), pump barrel (2) is in the spray tank (1), pump barrel (2) is the reciprocating piston force pump, its imbibition nozzle stretches into the bottom of spray tank (1), and its piston rod links to each other with rocker lever (5).Pump barrel (2) leads to air chamber (3) through outlet pipe (8), and outlet pipe (8) the beginning part of pump barrel (2) is acclivitous, and forms the inclination angle between the pump barrel (2).The two ends of air chamber (3) are respectively equipped with inlet (6) and liquid outlet (7), and inlet (6) communicates with the outlet pipe (8) of pump barrel (2), and liquid outlet (7) communicates with spraying parts (4).During work at spray tank (1) soup of packing into, operation rocker lever (5), soup enters air chamber (3) after pump barrel (2) is pressed into outlet pipe (8), enter behind the filter in air chamber (3) to spray parts (4) and spray.
