Chinese patent CN104875893A "Agricultural UAV Spray Boom Structure" discloses a plant protection UAV spray boom structure. The mechanism is connected by two connecting blocks respectively fixed on the landing gear and the spray boom. The installation of the cross chute and the convex strip is added to improve the connection stability; the structure in this patent is detachable, but it still needs to use operating tools, and the adjustment of the distance between the nozzles cannot be realized, but in the present invention, the folding of the spray rod and the nozzles can be realized. Spacing adjustment

Embodiment Construction

[0024] When working in farmland, the plant size and planting row spacing are different, and the nozzle spacing should be adjusted for specific field operations. Before the aviation spraying operation, the spray boom 2 is positioned on the vertical rod member of the front arch of the landing gear 1 by the spacing adjustment device 4, and the spray boom 2 is folded on both sides of the landing gear. According to parameters such as specific field plants and row spacing, select a suitable nozzle 3 and move the spray bars 2 on both sides axially to obtain a suitable nozzle spacing. After the spacing adjustment is completed, the spray boom 2 is deployed to the working position. There is a gap between the positioning part 14 of the landing gear and the pressure plate of the spray boom fastening ring 11. When the set screw 10 is inserted into the positioning screw hole of the pressure plate of the spray boom fastening ring 11 and tightened, the two pressure plates of the spray boom fa...

Abstract

The invention relates to an aviation electrostatic spraying device. The device mainly comprises two parts of a spraying rod adjusting device and an electrostatic atomization system. The spraying rod adjusting device mainly consists of such several parts as a rotating block, a fixed piece, a spraying rod and a fastening screw; the electrostatic atomization system includes an atomization system and an electrostatic generation device; the atomization system mainly consists of a medicine box, a diaphragm pump, a pipeline, a three-way valve, a nozzle and the like; and the electrostatic generation device mainly consists of a direct-current power supply, a high-voltage generator and an electrode. In the aviation electrostatic spraying device, the spraying rod can rotate and extend trough the rotating block to adapt to different spraying width requirements. The whole atomization system is insulated in liquid loop. The electrostatic spraying can improve the aviation spraying uniformity and reduce drifting. The aviation electrostatic spraying device realizes the nozzle gap adjusting problem in the aviation electrostatic spraying, improves the aviation spraying operation efficiency, improves the adaptability of aviation spraying to different plant protections, and reduces the operation time and the material cost.

Description

technical field [0001] The invention belongs to the field of aviation plant protection machinery, and relates to an aviation electrostatic spraying device, in particular to a spray rod device structure. Background technique [0002] Aerial spraying has been widely valued in plant protection operations. Aeronautical electrostatic spraying equipment can obtain better atomization effects, but it also poses certain restrictions on the modification of atomization devices during operations, and the adaptability to different spraying requirements in different environments is not enough. So far, there is no structural device for directly adjusting the nozzle spacing for aviation electrostatic spraying. [0003] At present, there are some drone boom structures that have been realized in China. Chinese patent CN204469973U "A Spray Boom Mechanism of Plant Protection UAV" discloses a spray boom mechanism of plant protection UAV, which can realize the rotation and folding of the spray b...
