Embodiment 1

[0028] The spraying equipment field fog droplet deposition distribution simulation test system of this embodiment is as follows: figure 1 As shown, the test frame 2 comprising a movable three-dimensional frame structure placed on a pair of rails 1, positioning holes with a spacing of 20 cm are distributed on each frame of the frame, and nylon ropes are used to pass through the positioning holes to form a three-dimensional coordinate grid. To arrange the test paper card. The traveling mechanism at the bottom of the test frame 2 is connected to the speed-regulating drive motor 3, specifically to the test frame 2 of the present embodiment, such as figure 2 , image 3 As shown, its bottom constitutes a moving pair by a slide block 2-1 and a track 1, and one side of the track 1 is fixed with a rack 1-1 meshed with a gear 3-1 driven by a speed-regulating drive motor 3 to form a driving 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...
