Jet rod spraying machine and jet rod replacing method thereof

Abstract

The invention relates to a jet rod spraying machine which comprises a suspension assembly, more than two jet rod air curtain assemblies, a liquid medicine transport assembly and an air supply assembly, wherein a suspension rod of the suspension assembly is provided with two fixed frames; two screwed holes have the opposite rotating directions; telescopic rods are installed on the two fixed frames; adjusting rods are rotatablely connected on the telescopic rods; fixed jet rods of the jet rod air curtain assemblies are connected with two movable jet rods by a jet rod replacing mechanism; a fixed bracket is connected with the telescopic rods by a connecting rod; a flexible spray pipe and a flexible air curtain pipe are connected on the fixed jet rods and the movable jet rods, the flexible air curtain pipe is positioned at the outer side of the flexible spray pipe, and the flexible air curtain pipe is provided with more than one row of air outlet holes along the arrangement direction of a spray head; the liquid medicine transport assembly and the air supply assembly are respectively connected and communicated with the respective flexible spray pipe and flexible air curtain pipe, so that spraying areas with multiple shapes and line spacing changes are formed; and the jet rod spraying machine can realize target spraying of pesticide, reduces drifting of fog drops, and meets the requirements of diseases and pest control operation of field plants, fruit trees, nursery stock and fence-frame-type plants.

Description

technical field [0001] The invention relates to a spray rod type sprayer and a spray rod conversion method thereof, belonging to the technical field of plant protection machinery. Background technique [0002] Since the beginning of the 21st century, plant protection machinery has begun to develop in the direction of professional machinery and multi-functionality. Boom sprayers and tunnel sprayers are two important forms of large-scale plant protection sprayers. The boom sprayer is mainly composed of a medicine box, a pressure pump, a spray boom and a nozzle connected to the spray boom. The liquid medicine in the medicine box is sprayed to the crops through the pressure pump, the spray boom and the nozzle for pest control. The boom sprayer is mainly used for the prevention and control of diseases and insect pests of field crops such as rice and wheat. The sprayer with the above-mentioned conventional structure has an open nozzle, which causes serious mist drift during spray...

AI Technical Summary

Problems solved by technology

In order to keep the droplets to settle in a relatively closed space, it is necessary to reduce the driving speed of the sprayer, thus affecting the working efficiency

[0003] Usually the boom sprayer is used for spraying field crops, but there are problems such as serious droplet drift and narrow use area. At present, general-purpose boom sprayers or other general-purpose sprayers are mainly used for hedge plant pest control operations Sprayers, but general plant protection equipment generally has problems such as low efficiency, high drift, and high pollution when performing plant protection operations on hedge-type plants, which seriously affect the quality of hedge-type plants, which restricts the work efficiency of hedge-type plants. The use frequency of special tunnel sprayers is seasonal, and the annual use efficiency is very low. Therefore, it is necessary to develop an air-assisted tunnel multifunctional boom sprayer that takes into account the pest control of field plants and hedge plants.
