Logical, the end of one of hydraulic cylinder is connected to by oil pipe 24 with hydraulic oil in hydraulic oil filling 16 and the oil pipe is equipped with switch
17, the first pressure switch includes the first cylinder barrel 20 being fixed in shell 1, and it is living to be equipped with first in one end of the first cylinder barrel 20
Stopper rod 21, the end of First piston bar 21 extend to outside shell 1, and the other end of the first cylinder barrel 21 passes through oil pipe 24 and hydraulic oil
It fills in 16 and is connected with the first check valve 18 on hydraulic oil connection and the oil pipe, hydraulic oil fills 16 tops and is equipped with air vapor valve
26, the air vapor valve 26 (being made of pressure valve (steam valve) and vacuum valve (air valve)), installation makes after can directly purchasing
With the effect of air vapor valve 26 is in order to keep hydraulic oil to fill the pressure equilibrium in 16, specifically when hydraulic oil fills inside 16
When pressure is greater than external, pressure valve (steam valve) is opened to which the gas filled hydraulic oil in 16 is discharged；When hydraulic oil fills in 16
When portion's pressure is less than external, vacuum valve (air valve) is opened, and extraneous gas is able to enter hydraulic oil and fills in 16；Another hydraulic cylinder
End be connected to the other end of the first cylinder barrel 21 and be connected with second one-way valve 19 on the oil pipe by oil pipe 24；The medical fluid
Injection device includes drug reservoir 2, second pressure switch, is equipped with medical fluid at the top of the drug reservoir 2 and mouth 6 is added, of course for
Guarantee leakproofness in drug reservoir 2, medical fluid, which is added in mouth 6 to be desirable to install, prevents the check valve of the medical fluid being added outflow (in figure
It is not drawn into), medical fluid is added above the shell 1 of 6 face of mouth and offers medical fluid inlet 3,2 bottom of drug reservoir and syringe needle 4
One end connection, the second pressure switch includes the second cylinder barrel 12 being fixed in shell 1, is equipped in one end of the second cylinder barrel 12
Second piston bar 13, the end of second piston bar 13 extend to outside shell 1, and the other end of the second cylinder barrel 12 passes through the first hose
9 are connected to 2 top side of drug reservoir, and third check valve 10 is connected in the middle part of the first hose 9, and 10 arrival end of third check valve is logical
It crosses the second hose 25 to be connected to outside shell 1, the 4th check valve 11, the entrance of the 4th check valve 11 is connected on the second hose 25
End is connect with the air inlet of the second hose 25.
In the present embodiment, the end of the First piston bar 21 outside shell 1 is equipped with the first pressing handle 22, described
Spring 15 is connected between first pressing handle 22 and 20 wall of the first cylinder barrel；The second piston bar 13 outside shell 1
End is equipped with the second pressing handle 14, also connecting spring 15 between the second pressing handle 14 and 12 wall of the second cylinder barrel.Spring
15 effect can be quickly sprung back after pressing the first pressing handle 22, second pressing handle 14.
In the present embodiment, for the ease of whole device to be clamped on straw or on stem, 1 lower part of shell is solid
Surely there is the fixing clamp 23 for being fixed on shell 1 on straw.
Drug injection is carried out to cotton using the hydraulic injector in above-described embodiment below: first by shell 1
Medical fluid is added mouth 6 from the medical fluid at 2 top of drug reservoir and is added in drug reservoir 2 by medical fluid inlet 3, then solid with fixing clamp 23
Surely the stem for living cotton, first turns off the switch 17, continuous pressing and unclamps the first pressing handle 22, due to the first check valve 18, the
The presence of two check valves 19, when release first presses handle 22, hydraulic oil fills 16 from hydraulic oil and flows by second one-way valve 19
Enter in the first cylinder barrel 20, hydraulic oil fills 16 internal pressures less than outside at this time, and the vacuum valve (air valve) of air vapor valve 26 is opened
It opens, extraneous gas is able to enter hydraulic oil and fills in 16 to make hydraulic oil fill the pressure equilibrium in 16；The first pressing hand is pressed again
Hydraulic oil in first cylinder barrel 20 can be pushed into oil pipe 24 and then liquid presses piston pole 8 is pushed to travel forward by handle 22, due to the
The advance distance that one pressing handle 22 presses every time is smaller, therefore needs through repeatedly the first pressing of pressing handle 22 could be by connecting plate
5, which travel forward, drives syringe needle 4 to be pushed into cotton stem；The second pressing handle 14 is pressed again to inject air by the first hose 9
To increase the pressure in drug reservoir 2 in drug reservoir 2, so that the medical fluid in drug reservoir 2 is injected cotton by syringe needle 4
In stem, after the completion of injection, the second pressing handle 14 is unclamped, air is soft by the inflow second of the 4th check valve 11 from the hole of bottom
In pipe 25, makes up the pressure difference in the second hose 25 and unclamp again the first pressing handle after second pressing 14 button of handle restores
22, turning on the switch 17 can be such that the hydraulic oil in hydraulic cylinder 8 flows back into hydraulic oil filling 16, and hydraulic oil fills 16 internal pressures and is greater than
The pressure valve (steam valve) of outside, air vapor valve 26 opens and then hydraulic oil is filled to the gas in 16 and is discharged, to make hydraulic
Oil fills the pressure equilibrium in 16, and the hydraulic oil in hydraulic cylinder 8, which flows back into during hydraulic oil fills 16, will drive syringe needle 4 from cotton
It is exited in stem, completes injection.It is administered since syringe is directly inserted on stem, changes the mode that traditional blades absorb, effectively
Improve pesticide utilization rate；Pesticide itself has certain toxicity, and direct injection makes the less exposed to pesticides smog of human body, reduces to people
Body injury；It does not need to be wasted in pesticide in soil and air volatilization, pollution unnecessary for environment can be reduced.
The limitation that technical solution of the present invention is not limited to the above specific embodiments, it is all to do according to the technique and scheme of the present invention
Technology deformation out, falls within the scope of protection of the present invention.
