Description

Multi-branch cleaning loop based on agricultural dispensing system and control method Technical Field The invention belongs to the technical field of agricultural precise pesticide application, and particularly relates to a multi-branch cleaning loop based on an agricultural dispensing system and a control method. Background The accurate and efficient pesticide preparation is a key link for guaranteeing the control effect of agricultural diseases and insect pests and reducing the hazard risks and environmental pollution. At present, two modes mainly exist in the dispensing operation in agricultural production, namely, firstly, the operation is widely performed manually, namely, an operator estimates the dosage empirically, and the weighing, pouring, stirring and mixing of the medicament are manually completed. The mode has the advantages of high labor intensity, low efficiency, large proportioning error (generally more than 10 percent) caused by human factors, direct influence on the pesticide application effect and easy incomplete control or crop phytotoxicity. Secondly, a partially automated simple dispensing device is adopted, and the equipment focuses on a single function, such as stirring or simple metering, and is usually only suitable for a certain type of liquid or solid medicament, so that the functional limitation is remarkable. The technical scheme mainly has the following outstanding defects that firstly, in the aspects of dispensing precision and control, a high-precision metering module and closed-loop control logic are lacked, the accurate proportional addition of the medicament and the water quantity can not be realized, and the development requirement of accurate agriculture is restricted. Secondly, in the aspect of medicament adaptability, particularly for solid dosage forms such as wettable powder, water dispersible granules and the like, the prior equipment generally lacks a special pretreatment mechanism, and if the equipment is directly put into a main mixing container, the problems of agglomeration, uneven dispersion and the like are easily generated, so that the efficacy of the medicament is influenced. In terms of system cleaning and pollution prevention, most devices are not provided with independent and targeted cleaning loops, and when different types of medicaments are switched for use, the residual medicaments are easy to cause cross contamination, so that the purity of the subsequent medicinal liquid is influenced, unknown harmful substances can be generated, and safety risks exist. The existing scheme generally ignores the datamation traceability of the dispensing process, key information such as operation parameters, consumption, time and the like cannot be recorded and remotely managed, so that the dispensing quality is difficult to monitor, and problems cannot be traced. Finally, the physical suitability of the device is poor, the device cannot flexibly butt against the application devices with different heights, and the operation complexity is increased. Therefore, developing an agricultural dispensing system and a control method which can realize automatic and accurate proportioning, widely adapt to different medicament forms, have thorough cross contamination prevention and cleaning capacity (one-step and one-step cleaning), and realize whole-process data tracing has become an urgent technical requirement for improving the standardization and intellectualization level of modern agricultural operation.
