Abstract
The utility model relates to a spray device, particularly a single-cylinder and dual-pressure sprayer which is characterized in that the utility model improves the ordinary sprayer, a water-absorbing valve and a water-discharging valve are added on the rear part of the cylinder, and thus, only one cylinder is used to realize that water is absorbed and discharged at the same time whether the piston is pushed forward or pulled backward; the utility model has the advantages of low price, high efficiency, small volume, light weight, duration, and easy repair.
Description
The utility model relates to a kind of injection apparatus, the two compression pesticide spray devices of a kind of single cylinder of saying so more specifically.
Existing power pump mainly is three cylinder piston pumps, and power 3-3.5 horsepower can be sprayed simultaneously for 4-8 people.Its power is big, and integral body is heavy, needs two people just can lift when mobile, and cost is also high.Rural area activity in production now is many to be that unit carries out with the family, generally carries out spray operation simultaneously with two people, and price is low, efficient is high, volume is little, in light weight, the durable sprayer of easily repairing so urgent hope has.
The purpose of this utility model is to increase a suction valve and a draining valve at the rear portion of cylinder, thereby has realized no matter pushing away or post-tensioning before the piston with a cylinder, and all the while is sucking and discharging.
The purpose of this utility model can realize by following technical proposals:
On the basis of existing agricultural motor sprayer, improve, its technical essential is: bent axle connects the connecting rod guide pad by connecting rod, the stopper rod of taking over a job before the connecting rod guide pad, the piston rod front end is provided with piston fixed thereon, suction hose assembly and suction hose, unloader drainpipe, former and later two suction valves are communicated with, and the front and back outlet valve is communicated with delivery port.
The utility model has following advantage compared with prior art:
1. simple in structure, volume is little, in light weight, save raw material.
2. increase work efficiency, easy to use safe and reliable.
Fig. 1 is a structural representation of the present utility model.
Describe the utility model in detail below in conjunction with accompanying drawing:
As shown in Figure 1, the concrete structure of the moving pump of single cylinder double-compressor is that bent axle 2 connects connecting rod guide pad 3 by connecting rod 1, the stopper rod 4 of taking over a job before the connecting rod guide pad, the piston rod front end is provided with piston fixed thereon 5, suction hose assembly 9 and suction hose 8, former and later two suction valves 6,6 ' connection, it also is connected with the drainpipe of unloader 11 sidewalls in addition, front and back outlet valve 7,7 ' be communicated with delivery port 10.
Its course of work is such: when pushing away before the piston, anterior pressure strengthens in the cylinder barrel, preceding suction valve pressurized sealing, preceding outlet valve pressurized is opened, and soup anterior in the cylinder barrel is by preceding outlet valve discharge, simultaneously, rear portion pressure reduces in the cylinder barrel, back draining valve seals thereupon, and back suction valve is opened, and the rear portion sucks soup in the cylinder barrel; When the piston post-tensioning, as a same reason, preceding outlet valve and back suction valve sealing, preceding suction valve and back outlet valve are opened, and cylinder barrel rear portion soup is through back outlet valve and outlet pipe discharge, and the cylinder barrel front portion charges into the soup from preceding suction valve.
