At the top of 3, self-priming is installed on the pedestal 1 and adjusts assembly, it includes self priming pump 6 which, which adjusts assembly, and the self priming pump 6 passes through
Included electricity generation module is connected to 2 drive shaft of gasoline engine, and the bottom of the water tank 4 is connected with the first tube body 40, the medicine-chest 5
Bottom is connected with the second tube body 50, is equipped with low water level alarm device 41, first tube body 40, the second tube body in the medicine-chest 5
50 are all connected to the input terminal of self priming pump 6, and the output end of the self priming pump 6 is connected to the rapid-result case 3 of mixing by third tube body 60,
The third tube body 60 is equipped with solenoid valve 61, and the rapid-result case 3 of the mixing is connected to spray gun 20, and the gasoline engine 2 is drivingly connected
In spray gun 20, the control of controller 7 is connected to self priming pump 6 and solenoid valve 61.
Gasoline engine 2 and self-priming adjust assembly and are separately fixed on pedestal, and operator backs on the body machine, uses self-priming tune
Assembly is saved, by being connected to the water inlet of water tank 4, water sucking self-priming is adjusted in assembly, works and drives specifically by gasoline engine 2
Dynamic electricity generation module is that self priming pump 6 is powered, and when work, is inhaled the medicine (liquid) of the water of water tank 4 and medicine-chest 5 simultaneously by controller 7
Enter, quickly mixed, solenoid valve 61 is then opened by controller 7, by mixed liquor high-pressure injection to the rapid-result case 3 of mixing, shape
At required pesticide liquid, then drives plunger pump to connect spray gun 20 in succession by gasoline engine 2 and carry out sprinkling medical fluid.
In the above process, controller 7 works, i.e. by Charge control regulating switch: first flow valve 400, second flow
Valve 51 adjusts the utilization rate of water, dose, enters that self priming pump mixing enters eventually into the water for mixing rapid-result case and medicine (liquid) ratio is
1: 20, such as: first flow valve 400, second flow valve 51 are adjusted to the first control shelves, it is big to mix 1 jin of water absorption of medicine in medicine-chest 5
About 20 jin, first flow valve 400, second flow valve 51 are adjusted to the second control shelves, mix about 30 jin of 1.5 jin of water absorptions of medicine, this
In the process, the normal spraying laxative of spray gun 20 is opened, PLC controller 7 closes the self-priming of self priming pump 6.
The low water level alarm device 41 includes two parallel bodies of rod 42, which is mounted on the bottom of water tank 4,
It is connected with movable floating ball 46 on the body of rod 42, is equipped on the water tank 4 immediately below floating ball 46 engaged therewith close
Switch 49, the controller 7 control the on-off of self priming pump 6 by receiving close to the electric signal of switch 49.
It is arranged with the annulus set 43 being slidably matched with it on the body of rod 42, cross bar is installed between two annulus sets 43
44, the floating ball 46 is mounted on the upper surface of cross bar 44 by the first vertical bar 45, and the lower end surface of the cross bar 44 is equipped with convex block
47, the bottom of the water tank 4 is equipped with groove 48 compatible with contact block 47, it is described close to switch 49 be located at groove 48 it is interior and
Work is matched with contact block 47.
The present invention, in work process, due to much more important than scarce medicine of water shortage, once because of water shortage, self priming pump 6 is by medicine
Medicine (liquid) in case 5 is directly driven in the rapid-result case 3 of mixing, is then sprayed by spray gun 20, in this way due to no diluted medicine
(liquid) concentration is higher, can by crops " burning " extremely, so, the present invention be provided with a low water level alarm device 41, original state,
Due to being full of suitable water in water tank 4, at this point, floating ball 46 is at the highest notch, as gasoline engine 2 drives plunger pump to connect spray gun in succession
20 carry out sprinkling medical fluid, and water is constantly reduced in water tank 4, until arrive as shown in figure 3, convex block 47 enters in groove 48, and approach
Switch 49 cooperates, and reaches close to switch 49 and detects position, transmits signals to controller 7 at this time, and controller 7 controls self priming pump 6
It stops working, simultaneously closes off solenoid valve 61, since, without water, so will not work, operator at this time i.e. should be to water in water tank 4
In case 4 plus water, as water level increases in water tank 4, floating ball 46 receives buoyancy increase, gradually rises along the body of rod 42, convex block 47 from
Until in initial position, water tank 4 plus water stops to maximum water level plus water in recessing 48, low water level alarm device 41 and then again
Repeated work.
First tube body 40 is equipped with first flow valve 400, and second tube body 50 is equipped with second flow valve 51, described
First flow valve 400 and second flow valve 51, which control, is connected to controller 7, controls 400 He of first flow valve by controller 7
Water, dose is adjusted in the realization of second flow valve 51, improves the utilization rate of dose, and self-priming adjusts what assembly maximum can limit the quantity
Save dose.
The top of the water tank 4 and medicine-chest 5 offers feed opening, and capping is mounted on the feed opening, when 4 He of water tank
5 material use of medicine-chest is over, by feed opening respectively to 4 Jia Shui of water tank and to 5 dosing of medicine-chest.
The spray gun 20 is equipped with the flow control valve 21 of control uninterrupted close to outlet end, is sprayed by adjusting spray gun 20
The uninterrupted for mixing medicine out is accomplished to be administered optimum state to sprayed crops.
The gasoline engine 2 uses 1E40FP-3Z gasoline engine, which is mounted on pedestal 1, it is described from
Sucking pump 6 uses miniature injecting type self priming pump, can pole using light-weighted 1E40FP-3Z gasoline engine, miniature injecting type self priming pump
Big reduction operator bears load, while miniature injecting type self priming pump can drawn while mix to water tank 4 and 5 material of medicine-chest
It closes, and is ejected into the rapid-result case 3 of mixing with higher jet power, realize quick mixing, can eliminate to the greatest extent needs
It transports clear water and mixes medicine, i.e., water is first filled into dosing (liquid) into water tank 4 again of water tank 4, be then stirred, then spray, this is numerous
The step of weight.
The bottom of the pedestal 1 is equipped with movable pulley 8, which has brake gear, is moved easily.
The controller 7 uses Siemens s7-222 PLC controller, built-in to control CPU, write-in control program, volume
Small control precision is high, realizes to first flow valve 400, second flow valve 51, solenoid valve 61 and self priming pump logic control, real
The now normal work of the spraying machine.
The present invention adjusts assembly using self-priming, can the maximum saving dose limited the quantity, such as original Backpack powered sprayer one
Its 50 mu of ground of laxative, being now improved to self-priming mixing, application can achieve 80-100 mus one day after, has not only saved the time but also has alleviated
Weight bearing improves spray working efficiency, and main is to eliminate to need to transport mixed this heavy program of medicine of clear water, for suitable
It is extremely applicable in for paddy field spray.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
