High-range air-assisted vertical spraying machine

Abstract

The invention discloses a high-range air-assisted vertical spraying machine, and relates to the technical field of agricultural equipment. The high-range air-assisted vertical spraying machine comprises a bottom rack, an air inlet barrel is installed on the bottom rack, the upper end of the air inlet barrel is connected with a flow guide air outlet box, a lower end opening of the air inlet barrelis communicated with the atmosphere, an upper end opening of the air inlet barrel is connected with a lower end opening of the flow guide air outlet box in a sealed manner, and a draught fan is installed in the air inlet barrel; and an inner flow guide box is arranged in the flow guide air outlet box, a flow guide air cavity is formed between the inner flow guide box and the flow guide air outletbox, a lower flow guide plate is connected between the lower portion of the inner flow guide box and the flow guide air outlet box, an opening in the upper end of the flow guide air outlet box is an air outlet, upper flow guide plates arranged at intervals are installed in the air outlet, and a nozzle assembly with an upward nozzle is further installed in the air outlet. According to the high-range air-assisted vertical spraying machine, the power of the draught fan is 15 KW, and meanwhile, the air outlet is of a flat structure, so that the spraying machine has the advantages of being long inspraying range, large in breadth and uniform in pesticide spraying, and is suitable for quick pesticide spraying of double-row trees with the height of 4-15 m.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to a high-range air-driven vertical sprayer. Background technique [0002] In recent years, air-driven sprayers have been used on a large scale in grassland locust eradication and forest tree pest control. The air-driven sprayer has the advantages of large spray width, good droplet uniformity, high pesticide use efficiency and less environmental constraints. The air-driven sprayer uses a liquid pump to pressurize the liquid medicine and atomize it into coarse mist droplets through the nozzle, then spray it out, and then the high-speed airflow generated by the fan is further atomized into fine mist droplets and transported to a long distance, so as to achieve the mist effect . [0003] However, there are obvious defects in the wind-driven sprayer in the prior art: 1) the range of the liquid medicine is limited, and it cannot be used for the spraying of the tall trees...
