Method for replacing jet rod of spraying machine and mechanism thereof

Abstract

The invention relates to a method for replacing a jet rod of a spraying machine, which is realized by adjusting the position change of side jet rods arranged at the two sides of a fixed jet rod and the length or installation position of an adjusting support rod connected between the side jet rods and a vertical jet rod; a spray pipe is connected and communicated with a vertical spray pipe provided with a spray head by a transverse spray pipe provided with a spray head through a flexible pipe, and the vertical spray pipe and the transverse spray pipe are respectively connected at the inner sides of the fixed jet rod and the vertical jet rod; and the spray pipes can form a follow-up change-tunnel-type spray pipe by the position change of the fixed jet rod, the side jet rods and the verticaljet rod, so that line spacing change of fruit trees and fence-frame crops as well as the spraying requirements of the fruit trees and the fence-frame crops with different shapes can be adapted. The invention has the characteristics of convenient adjustment of the positions of the spray pipes, pesticide application efficiency increment and strong applicability.

Description

technical field [0001] The invention relates to a method for changing the spray rod of a sprayer and its mechanism, and belongs 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. Generally, the boom sprayer is used for spraying pesticides on field crops such as rice and wheat; the tunnel sprayer has ...

AI Technical Summary

Problems solved by technology

Generally, the boom sprayer is used for spraying pesticides on field crops such as rice and wheat; the tunnel sprayer has spray bars fixed on both sides of the tunnel, and for fruit trees such as apples and pears, there are special tunnel sprayers for orchards. Hedgerow crops do not have special spraying equipment, and are usually replaced by spray rods, resulting in poor penetration, low spraying efficiency, high residue and high pollution in plant protection operations for hedgerow crops, which seriously affects hedgerow crops. The quality of trellis crops restricts the efficiency of spraying trellis crops

Secondly, boom-type or tunnel-type sprayers are only suitable for the application of certain types of crops, and the frequency of use is seasonal, and the annual use efficiency is very low; there is also a crop cultivation method where the land is mostly 2 to 3 seasons a year, In particular, it is very practical to need a multi-purpose plant protection machine to improve the efficiency of the machine.
