The utility model discloses a theory of operation:
principle of liquid storage
When liquid medicine liquid level detection device detected the liquid medicine liquid level and is less than the setting value in the liquid medicine holding vessel, main control unit 11 can give the staff through wireless communication module 12 with the too low information transmission of liquid medicine liquid level, the staff can go in inserting the liquid medicine holding vessel through advancing medicine hole 2 with the liquid medicine conveyer pipe, the shell fragment that advances in medicine hole 2 can be along with the inserting shrink of liquid medicine conveyer pipe advances during the liquid medicine holding vessel, then the liquid medicine conveyer pipe can supply the liquid medicine of the inside, liquid medicine liquid level detection ware 26 can real-time detection current liquid medicine, when the liquid medicine input is about to be sufficient, can remind the staff, the liquid medicine conveyer pipe can be taken out to the staff, the last shell fragment of medicine hole 2 can the reconversion.
When water level detection device 14 detects the water level and is less than the setting value in the clear water holding vessel, main control unit 11 can send the information that the water level was crossed to the low height for the staff through wireless communication module 12, and during staff's water passed through inlet opening 13 with the water pipe and inserted the clear water holding vessel, during the shell fragment in the inlet opening 13 can shrink into the clear water holding vessel along with the entering of water pipe, then the clear water just can supply into in the clear water holding vessel and go. When the water level detector detects 14 that the water level is sufficient, the worker is reminded, and the worker stops conveying the clean water to the clean water storage tank. The elastic sheet on the water inlet hole 13 can be restored to the original state along with the extraction of the water pipe.
Principle of pesticide proportioning
The chemical liquid storage tank delivers the chemical liquid to the mixing tank 5 through the chemical liquid flow pipe 23, and the clear water storage tank delivers the clear water to the mixing tank 5 through the water flow pipe 21.
There is no solution in the mixing tank 5: the main controller 11 controls the amount of the liquid medicine and the amount of the clear water flowing into the mixing tank 5 by controlling the liquid medicine flow regulating valve 16 and the water flow regulating valve 20 so as to achieve the pesticide concentration of the corresponding mixed liquid. Firstly, the staff inputs the total amount and concentration of the mixed liquid to be proportioned, then the concentration of the liquid medicine is input, then the main controller 11 calculates the amount of the liquid medicine and the amount of the clear water to be put into the mixing tank 5, finally, the main controller 11 controls the proper opening degrees of the liquid medicine flow regulating valve 16 and the water flow regulating valve 20, and controls the opening time so as to input the corresponding liquid medicine amount and the clear water amount calculated by the main controller 11, so that the precision of the proportioned pesticide concentration is higher than that of the proportioned pesticide.
When still remaining the mixed liquid that does not use up in blending tank 5, the concentration of this mixed liquid has been recorded above the main control unit 11, at first main control unit 11 can know how much solution still remains in blending tank 5 through mixed liquid level detection device 7, the staff need input the volume and the concentration of this mixed liquid that needs the ratio to main control unit 11 through wireless communication module 12, main control unit 11 can automatic calculation corresponding liquid medicine volume and the clear water volume that need put into in blending tank 5, then main control unit 11 can control liquid medicine flow control valve 16 and water flow control valve and adjust the suitable aperture of 20, thereby control open time inputs corresponding liquid medicine volume and the clear water volume that main control unit calculated.
Principle of mixing and stirring
After the ratio solution is accomplished, main control unit 11 can control stirring rod 18 and water pump and carry out work, and control stirring rod 18 is anticlockwise stirs the mixture, and a dip angle is personally submitted with the level to the water pump delivery port, and two water pumps are the center and pile up, and the mixed liquid is intake from the water pump water inlet, gets rid of from the water pump delivery port, and the water pump delivery port will be thinner than the water inlet, and this limit mixed liquid's of water pump direction and stirring rod 18 mixed liquid opposite direction makes the more abundant mixture of mixed liquid like this.
Principle of storing liquid medicine
The mixing tank is equivalent to a totally-enclosed container when the mixed liquid flow regulating valve, the liquid medicine flow regulating valve and the clear water flow regulating valve are closed, and the opening on the liquid storage tank is designed to ensure that the first night tank is a semi-enclosed container, so that the volatilization of the liquid medicine is slowed down.
