Wrapped target spraying device

Abstract

The invention discloses a wrapped target spraying device, comprising a screw lifting platform, four target mechanisms and a DSP (digital signal processor) controller, wherein two connecting rods on the screw lifting platform are connected with the middle part of a spraying frame; one ends of cylindrical racks of the four target mechanisms with the same structure are respectively embedded in a chute of each target mechanism; stepping motors are arranged on the side surfaces of the chutes, and gears on shafts of the stepping motors are engaged with teeth on the cylindrical racks; the other ends of the cylindrical racks are welded on one ends of spraying arms, and a steering gear supporting plate is arranged at the other ends of the spraying arms; steering gears are arranged on one side of the steering gear supporting plate, and shafts of the steering gears are fixedly connected with sprayer fixing seats provided with sprayers after passing through the steering gear supporting plate; the four target mechanisms are uniformly distributed on the spraying frame by virtue of extension arms of the chutes of the target mechanisms; and the DSP controller is fixed on a lower support plate and is electrically connected with the five stepping motors and the four steering gears. The wrapped target spraying device is expected to further improve the deposition rate of spray droplets and alleviate environment and food safety problems caused by excessive application of chemical agents.

Description

technical field [0001] The invention relates to a spraying device, in particular to an enveloping target spraying device in the field of agricultural engineering. Background technique [0002] The traditional rough spraying method causes a large number of mist to be sprayed onto the surface of the soil around the crops by mistake, resulting in increasing environmental problems such as soil compaction and "3s" residue residue, pest resurgence, and pest resistance. At the same time, excessive The residues of pesticides and fertilizers on crops will cause food safety problems. However, in order to ensure stable and increased grain production, chemical agents have to be used. Targeting technology can effectively solve this conflict, mainly through image processing technology to selectively spray according to the presence or absence of target objects. The introduction of this technology can not only reduce the amount of spraying agent used, but also improve the effective deposit...

Problems solved by technology

Electrostatic spraying devices can effectively improve the effective deposition rate of droplets, but this method has poor droplet penetration performance during the spraying process, so it has not been widely promoted
