Simulation test system and test method for field fogdrop deposition distribution of pesticide applying device

Abstract

The invention relates to a simulation test system and test method for field fogdrop deposition distribution of a pesticide applying device and belongs to the technical field of agriculture test. The system comprises a test frame, a driving device, an airflow generator, a damping screen and a computer control device. According to the simulation test system provided by the invention, the relative movement principle is reasonably utilized, control parameters are set according to a traveling speed of a tested pesticide applying device in field operation and the relative airflow formed by the spraying operation under corresponding traveling speed under the condition that the pesticide applying device is not moved, the traveling of the moveable test frame is utilized to realize the dynamic simulation sampling, the fogdrop motion matched with the practical condition is generated and the test result, such as, a variable coefficient of three-dimensional space deposition distribution of sprayed fogdrop basically consistent to the field practical condition, and the like, can be acquired, so that the test precision can be effectively increased, the large manpower and material resources for field test are avoided, the test cost is saved, the limitation of crop growth reason is avoided and the test period is shortened.

Description

technical field [0001] The invention relates to a computer-controlled testing device, in particular to a simulation testing system for field mist deposition distribution of pesticide application equipment, and also relates to a testing method using the system, which belongs to the technical field of agricultural testing. Background technique [0002] The uniformity of droplet deposition distribution is an important basis for evaluating the field operation quality of pesticide application equipment, and it is also a key factor affecting the effective utilization rate of pesticides. At present, the field test of spraying equipment for the determination of droplet deposition distribution is mainly to move the tested spraying equipment to the field for spraying operations, and rely on manual distribution and sampling on the target crops. Due to many uncontrollable factors in the field test, there are disadvantages such as low test efficiency and large measurement error, and it t...
