Boom sprayer

Abstract

The invention provides a boom sprayer which comprises a sprayer vehicle provided with a power driving system. A pesticide liquid mixing system and a spraying system are mounted at the tail of the sprayer vehicle, and the pesticide liquid mixing system comprises a water tank, an original pesticide tank, a diaphragm pump, an electromagnetic valve, a proportioning valve, a three-way valve and pipe fittings; the spraying system comprises a balance mechanism and a spraying device, the balance mechanism comprises a front hoisting bracket, a rear hoisting bracket, hoisting arms, hoisting cylinders, a first suspension arm, a second suspension arm, a boom frame and tension springs, the spraying device comprises a spraying bracket, and a plurality of groups of nozzles are arranged on the spraying bracket (321). The boom sprayer has the advantages that the concentration of required pesticide liquid can be adjusted according to different land parcels or diseases and pests, accordingly, wastage of pesticides can be reduced, the boom sprayer is wide in spraying range, the pesticide receiving areas can be increased, the pesticide liquid can be sufficiently sprayed, and the utilization rate of the pesticides can be increased; the boom sprayer can adapt to farmlands under different land conditions, is high in work efficiency and can work stably; the drift rate of the pesticides in spraying procedures can be reduced, accordingly, environmental pollution can be abated, and expected effects of preventing the insects and the diseases for crops can be realized.

Description

technical field [0001] The invention belongs to the field of spray machines, in particular to a boom spray machine. Background technique [0002] At present, the product technology of the boom sprayer in the existing market is mainly that the liquid medicine is mixed into a whole box, and stirred by jet technology. When there is liquid medicine residue, it is not easy to clean, and the residual mixed medicine after treatment is easy to cause environmental pollution; When spraying the same land and different pests and diseases, the proportion of the liquid medicine cannot be adjusted, resulting in a waste of liquid medicine; when spraying the liquid medicine, it cannot be divided into multiple branches to spray, resulting in insufficient spraying, so that the crops are insect-resistant, Disease prevention does not achieve the desired effect. [0003] At present, the boom system of the working part of the domestic boom sprayer consists of a lifting arm, a lifting bracket, a s...

Problems solved by technology

During the spraying process, the lowered end is easy to collide with the crop seedlings, causing damage to the spray rod, and the other end is raised away from the seedlings, causing the sprayed pesticide to drift with the wind and pollute the environment, and the crops cannot achieve the effect of insecticide, wasting resources.

The overall poor adaptability, low work efficiency, unstable work, waste of resources and pollution of the environment in the work process
