Abstract

The invention relates to an online test system for mobile dynamic mist distribution performance, and belongs to the technical field of sprayer test equipment. The system comprises a group of mist distribution acquisition devices; the bottoms of the mist distribution acquisition devices are respectively provided with a weight sensor; the output end of the weight sensor is connected with the input end of an acquisition card; an automatic rewinding reel is arranged on a mobile device; the acquisition card is in communication connection with a portable computer through a data wire; the portable computer is connected with a dynamic control circuit; a 485 communication module of the dynamic control circuit is connected with a corresponding port of a mater chip; and the control output end of the master chip is respectively connected with a motor controlled end and a pressure-regulating valve of a nozzle water supply pump through an isolation amplifier circuit. The online test system tests nozzles on line, and also tests the dynamic spray performance of various nozzles when the flow rate and the water supply pressure are changed so as to comprehensively understand and evaluate the performance of the tested nozzles.

Description

technical field [0001] The invention relates to a testing device, in particular to a mobile dynamic fog volume distribution performance online testing system, which belongs to the technical field of spraying equipment testing equipment. Background technique [0002] As far as the applicant knows, in agricultural plant protection operations and industrial spraying operations, the stability of the sprinkler head or combined sprinkler head work is very important. Usually, after the nozzle works for a period of time, the nozzle hole will be worn or blocked, which will affect the effect of the spraying operation. If there is no regular inspection and testing, the effect of pesticide application will be reduced in agricultural plant protection, and waste or defective products will be produced in industry. For a long time, the test of the nozzle needs to be disassembled and sent to the laboratory for testing, so it is very inconvenient, and in many occasions, the disassembly of th...
