Description
Technical field
This utility model relates to a kind of based on the PLC online liquid proportion device controlled.
Background technology
Current plant protection spraying machine tool obtains very big development, and the key link having become as in agricultural and forestry production process of spraying insecticide, the good harvest for agricultural product brings guarantee. Traditional sprayer machine adopts pesticide and dilution water premix mode, there is mechanization degree low; Distributing precision is low, and the utilization rate of pesticide is not high; Exhaustless blended cannot reclaim; People contacts with pesticide, and poisoning easily occurs; Later stage cleans the series of problems such as medicinal liquor barrel difficulty.
Summary of the invention
The purpose of this utility model is in that to provide a kind of based on the PLC online liquid proportion device controlled, when equipment for plant protection spraying agent, can by dilution water and pesticide real-time mixing match, simple in construction online, and response speed is fast, stable performance.
The purpose of this utility model is realized in, a kind of based on the PLC online liquid proportion device controlled, including three-cylinder plunger pump, ejector, water tank, medicine-chest, flow transducer, PLC, peristaltic pump, control panel and shower nozzle, the water inlet of plunger displacement pump is connected to the water return outlet of plunger displacement pump and the outlet of ejector respectively through conduit, two inlets of ejector respectively connected the liquid outlet of flow transducer and the liquid outlet of two peristaltic pumps, two peristaltic pumps are arranged in parallel, the inlet of two peristaltic pumps respectively connected two medicine-chests, the inlet of flow transducer is connected to water tank, flow transducer and described peristaltic pump are all connected with PLC, the outlet of plunger displacement pump is connected to shower nozzle.
During utility model works, by control panel input concentration, plunger displacement pump is driven high speed rotating by small two stroke gasoline, water is through flow transducer, data on flows is passed to programmable logic controller (PLC) PLC and controls peristaltic pump flow through calculating, medicament is squeezed into ejector and mixes with water by peristaltic pump, and mixed liquor is inhaled into plunger displacement pump pressurized liquid spray, 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. Such as, when a certain pesticide needs proportioning 5/10000ths, input " 5 " on a control plane;Needing to change concentration when being 18/10000ths, input " 18 ", system can detect current discharge and calculate and control pesticide flow. This device adopts the mixed medicine of the water inlet at plunger displacement pump, can reach better to mix drug effect fruit, and concentration can control break in real time.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Fig. 1 is attachment structure schematic diagram of the present utility model.
Detailed description of the invention
A kind of based on the PLC online liquid proportion device controlled, as shown in Figure 1, including three-cylinder plunger pump 2, ejector 6, water tank 8, medicine-chest 12, 13, flow transducer 7, PLC9, peristaltic pump 10, control panel 11 and shower nozzle 3, the water inlet 5 of plunger displacement pump 2 is connected to the water return outlet 1 of plunger displacement pump and the outlet of ejector 6 respectively through conduit, two inlets of ejector 6 respectively connected the liquid outlet of flow transducer 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 respectively connected two medicine-chests 12, 13, the inlet of flow transducer 7 is connected to water tank 8, flow transducer 7 and described peristaltic pump 10 are all connected with PLC9, the outlet 4 of plunger displacement pump 2 is connected to shower nozzle 3.
