Pulverizer wind cone with flow-guided structure

Abstract

The invention relates to a pulverizer wind cone with a flow-guided structure, consisting of an air inlet cylinder (6), a ball arc flow-guided cellular board (1), a hoop (4) and a link frame (5). The air inlet cylinder is formed by a vertical cylindrical air pocket (2) and a biconical platform air pocket (9) that is symmetrical at two ends and placed horizontally in orthogonality; the middle crosssection inside the air inlet cylinder (6) is provided with a ball arc flow-guided cellular board (1) on which circular holes are evenly distributed, and the outline is in an ellipsoid arc shape. The invention can be applied to a pulverizer, in particular to a pulverizer using an air-flow auxiliary type spray beam as well as occasions where air curtain needs to be produced. The flow-guided structure based on the ball arc flow-guided cellular board ensures that air fluid flows out of the wind cone evenly to form a uniform air curtain, thereby the invention is simple and economical and has obvious effect. The wind cone can effectively control fog drip movement, reduce fog drip loss, increase deposition of pesticide on a target, improve the using ratio of pesticide and reduce the environmental pollution.

Description

Technical field: [0001] The invention belongs to the field of spraying systems, and in particular relates to a wind-assisted air cylinder for forming an air curtain of a boom sprayer, in particular to a method of using a honeycomb ball arc deflector to form a flow guide channel and changing the airflow formed by the fan. Movement direction, so that the direction of air flow movement is evenly distributed along the length direction of the wind-assisted air cylinder, so that the wind speed of the air outlet of the air-assisted air cylinder has a better consistency in the length direction of the air-assisted air cylinder, forming a uniform air curtain, achieving reduction The purpose of small fog droplet drift. Background technique: [0002] my country's spraying equipment is guided by high-capacity spraying technology. The amount of spraying liquid per unit area is large, and the diameter of the sprayed droplets is large. It is difficult to adapt to the biological characterist...

AI Technical Summary

Problems solved by technology

However, the wind speed flowing out of the air duct, especially the wind speed distribution when the airflow reaches the top of the crop, has a great influence on the uniformity of spray distribution and the uniformity of droplet deposition

If the wind speed is too low, it will be difficult for the airflow to turn the branches and leaves, and cannot penetrate the plants. On the contrary, if the wind speed is too high, the airflow will penetrate the plants, hit the ground and rebound, thereby taking away the mist droplets, resulting in waste of liquid medicine and environmental pollution.
