Self-propelled boom sprayer

Abstract

The invention relates to a self-propelled boom sprayer, which belongs to the technical field of plant protection machinery. A spraying device frame is mounted on a gantry of the sprayer; the spraying device frame is provided with an upper horizontal beam rail and a lower horizontal beam rail fixedly connected with each other; the middle part of the upper horizontal beam rail is connected with the upper end of a piston rod of a vertical oil cylinder; the two ends of the upper and the lower horizontal beam rails form horizontal moving pairs together with an upper and a lower sliding rods respectively; the upper and the lower sliding rods are fixedly connected through an upright rod, and the middle part of the upright rod is connected with the external end of a piston rod of a horizontal oil cylinder; the external end of the upper horizontal sliding rod is hinged with a cylinder body of one rototary oil cylinder; the external end of the lower horizontal sliding rod is hinged with the inner end of a deformation spraying rod; the external extending end of the piston rod of the rotary oil cylinder is hinged with the middle part of the deformation spraying rod; and nozzles distributed at intervals and gas-pockets which discharge gas towards the nozzles are mounted on the horizontal spraying rod and the transformation spraying rod below the lower horizontal beam rail. The self-propelled boom sprayer has the characteristics of good adaptability, wide application range, convenience in operation and good fog drop drifting effect.

Description

Technical field [0001] The invention relates to a sprayer, in particular to a self-propelled boom sprayer, belonging to the technical field of plant protection machinery. Background technique [0002] The operation effect of plant protection equipment directly affects the growth and harvest of crops. Once the control is not timely or the control effect is not good, the crop production will be reduced. As an important plant protection machine, the spray bar sprayer is widely used, mainly for the prevention and control of field diseases and insect pests. Existing boom sprayers mainly have the following shortcomings: single function, narrow use area and serious droplet drift. [0003] The search found that the Chinese patent application with application number 201010132576.5 discloses a boom sprayer, including a suspension assembly, two or more boom air curtain assemblies, a liquid medicine delivery assembly and an air supply assembly; The conveying assembly and the air supply assem...

Problems solved by technology

The existing boom sprayers mainly have the following disadvantages: single function, narrow use area and serious mist drift

However, this technical solution can only spray fruit trees, and is not suitable for field crops (wheat, rice, etc.) and fruit trees are seedling operations, and has a single function

Experiments have shown that when the fruit tree is a seedling, the rods in the symmetrical ∏-shaped mechanism on both sides cannot move up and down (the distance between the left and right can only be adjusted by rotating the guide rod), so it cannot be suitable for the height of the fruit tree seedlings, so that the installation The mist droplets produced by the spray device on the Π-shaped mechanism are lost into the air in large quantities; on the other hand, because the spray device is a ring-shaped multi-nozzle structure with fans installed, the fan generates high-speed airflow to drive the mist droplets forward during operation. Seedling fruit trees have fewer leaves and a thin canopy. Only a small amount of droplets driven by high-speed airflow can be sprayed on the canopy target, and most of them will be sprayed on the ground and in the air.
