Description
Technical field
The present invention relates to a kind of online liquid proportion device of controlling based on PLC.
Background technology
Plant protection spraying machine tool has obtained very large development at present, sprays insecticide and becomes the key link in agricultural and forestry production process, for the good harvest of agricultural product has brought guarantee. Traditional sprayer machine adopts agricultural chemicals and dilution water premix mode, exists mechanization degree low; Distributing precision is low, and the utilization rate of agricultural chemicals is not high; Exhaustless blended cannot reclaim; People contacts with agricultural chemicals, and poisoning easily occurs; Later stage cleans medicinal liquor barrel difficulty and waits series of problems.
Summary of the invention
The object of the present invention is to provide a kind of online liquid proportion device of controlling based on PLC, in the time of equipment for plant protection spraying agent, can be by dilution water and the online mixing match in real time of agricultural chemicals, simple in structure, reaction speed is fast, stable performance.
The object of the present invention is achieved like this, a kind of online liquid proportion device of controlling based on PLC, comprise three-cylinder plunger pump, ejector, water tank, medicine-chest, flow sensor, PLC, peristaltic pump, control panel and shower nozzle, the water inlet of plunger displacement pump is connecting the water return outlet of plunger displacement pump and the delivery port of ejector by conduit respectively, two inlets of ejector are connecting respectively the liquid outlet of flow sensor and the liquid outlet of two peristaltic pumps, two peristaltic pumps are arranged in parallel, the inlet of two peristaltic pumps is connecting respectively two medicine-chests, the inlet of flow sensor is connecting water tank, flow sensor and described peristaltic pump are all connected with PLC, the delivery port of plunger displacement pump is connecting shower nozzle.
When the present invention works, by control panel input concentration, plunger displacement pump drives High Rotation Speed by small two stroke gasoline, water is through flow sensor, data on flows is passed to programmable logic controller (PLC) PLC and control peristaltic pump flow through calculating, peristaltic pump is squeezed into ejector by medicament and is mixed with water, and mixed liquor is inhaled into plunger displacement pump and pressurization is sprayed, and unnecessary mixed liquor is back to water inlet through water return outlet; When pilot plunger pump pressure or rotating speed, when discharge changes, the flow of peristaltic pump also changes with it. For example, in the time that a certain agricultural chemicals needs proportioning 5/10000ths, input " 5 " on chain of command; Need to change concentration is 18/10000ths o'clock, input " 18 ", and system can detect current discharge and calculate and control agricultural chemicals flow. This device adopts the mixed medicine of water inlet at plunger displacement pump, can reach better mixed drug effect fruit, concentration control break in real time.
Brief description of the drawings
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Fig. 1 is syndeton schematic diagram of the present invention.
Detailed description of the invention
A kind of online liquid proportion device of controlling based on PLC, as shown in Figure 1, comprise three-cylinder plunger pump 2, ejector 6, water tank 8, medicine-chest 12, 13, flow sensor 7, PLC9, peristaltic pump 10, control panel 11 and shower nozzle 3, the water inlet 5 of plunger displacement pump 2 is connecting the water return outlet 1 of plunger displacement pump and the delivery port of ejector 6 by conduit respectively, two inlets of ejector 6 are connecting respectively the liquid outlet of flow sensor 7 and the liquid outlet of two peristaltic pumps 10, two peristaltic pumps 10 are arranged in parallel, the inlet of two peristaltic pumps 10 is connecting respectively two medicine-chests 12, 13, the inlet of flow sensor 7 is connecting water tank 8, flow sensor 7 and described peristaltic pump 10 are all connected with PLC9, the delivery port 4 of plunger displacement pump 2 is connecting shower nozzle 3.
