Abstract

The utility model relates to an agricultural sprayer. The utility model is mainly composed of two double section one way valves, two liquid delivering pipes, a medicine liquid barrel, a three-way pipe, a high pressure kettle, and a spraying pipe, wherein, the two double section one way valves are respectively connected with the three-way pipe and the liquid delivering pipes; the head ends of the liquid delivering pipes are connected with high pressure balls which are positioned on the center of a pedal plate. When an operator walks, the feet of the operator rise and fall, the liquid is sucked and is pressed. Compared with the prior art, the utility model has the advantages of lightened labor strength, increased work efficiency, no medicine liquid leakage, convenient use, and low production cost, and in addition, a compressing device which is not provided with a worn piece dose not need maintaining.

Description

Foot-operated sprayer

The utility model is a kind of agricultural sprayer unit.

Because the damage by disease and insect of crops usually causes crop production reduction or total crop failure, therefore, the control of diseases and pests of agronomic crop is very important.Peasant's knapsack sprayer generally commonly used is sprayed insecticide with prevention and elimination of disease and pests at present.Now Chang Yong sprayer mostly is the type of inflating and strut type, and the type efficient of inflating is low, and the labour intensity height.Strut type moreover because the soup outflow appears in use compressed pipe and piston wear, is seeped into the person and operator's pesticide poisoning occurs because the strong point on people's shoulder, and with the violent moulded rod of hand, causes from getting involved as formula to the user.

The purpose of this utility model is a kind of sprayer of being different from prior art for the pressure mode of design, makes the operator in the process of walking, has promptly alleviated labour intensity, can not cause the agricultural chemicals seepage again.

The utility model is such:

As shown in Figure 1, be fixed with two binodal check valves (4) that structure is identical at pesticide solution bucket (1) back side, binodal check valve (4) adopts two check valve tandem compound structures, a liquid in-out mouth (13) is arranged in the middle of two check valves, being liquid outlet (9) above, is inlet (12) below; The inlet (12) of binodal check valve (4) is connected with medicinal liquor barrel (1); The liquid outlet (9) of binodal check valve (4) links to each other with three-way pipe (3).Two mouths of three-way pipe (3) connect the liquid outlet (9) of two binodal check valves respectively, and another mouth connects high pressure kettle (2); Article two, foot-operated woven hose (5) is gone up the liquid in-out mouth (13) of termination binodal check valve (4), and the lower end respectively connects a smash (7), and smash (7) is fixed in the middle of the pedal (6).

Operation principle of the present utility model is: will fill soup in the medicinal liquor barrel (1).The operator is through pedal (6) on the pin, lifts one by one of when walking and falls soup is sucked the last valve that enters binodal check valve (4) in the smash (7) again by woven hose (5), and enter high pressure kettle (2) through liquid outlet (9).Step on so repeatedly and lift several times, soup just is pressurized in high pressure kettle (2), at this moment opens the minor valve on the injection spray pipe (8), and soup just sprays from shower nozzle.

The utility model has the advantages that: because compression set underfoot, when lifting pin, walking finishes the imbibition program, body weight is finished the hydraulic fluid function by pedal when stopping over, alleviated labour intensity than prior art, improved operating efficiency and compression set does not have wear-out part, need not maintain, soup can seepage, easy to use, part is plastics or rubber, and production cost is low.
