An air curtain type airflow auxiliary diversion system

Abstract

The invention relates to an air curtain type airflow auxiliary diversion system, and belongs to the field of plant protection machines. An air speed and air direction sensor is arranged at the top of a rack, and two transmission devices and two diversion control rods are further arranged. Holes are formed in the two diversion control rods, and a front row of air guide barrels and a rear row of air guide barrels which correspond to the two diversion control rods are sleeved with the two diversion control rods respectively. The two transmission devices are mounted at the two ends of the rack respectively and each connected with one end of the corresponding diversion control rod. The other ends of the diversion control rods are mounted on the rack. The motion direction and motion speed of natural air in a work environment are measured through the air speed and air direction sensor, on the one hand, the rotating speed of an axial flow fan is changed by adjusting the work frequency of a frequency converter, the airflow speed of the air guide barrels is controlled, and on the other hand, the transmission devices drive the diversion control rods to rotate on the rack, and therefore the air guide barrels are driven to rotate, and the airflow motion direction of the air guide barrels is adjusted. The system can be applied to a boom sprayer, and therefore the penetrating power of mist drops is effectively improved, and drifting of the mist drops is reduced.

Description

technical field [0001] The invention relates to an air curtain type airflow auxiliary diversion system, which belongs to the field of plant protection machinery. Background technique [0002] At present, with the rapid development of science and technology, large and medium-sized agricultural mechanized spraying equipment will become the mainstream operating equipment in field operations. Features such as less pollution have already been promoted and tested in some farms. The lower abdomen of the air curtain airbag of the existing air curtain type boom sprayer is provided with small holes facing the ground, and the air curtain blown out by the small holes is used to force the small droplets to the crop canopy to reduce the drift of the droplets. Canopy shielding, the deposition of fog droplets on the lower stems and leaves of crops is less, the uniformity of pesticide application is poor, and it cannot resist the interference of natural wind well, especially when the natura...

AI Technical Summary

Problems solved by technology

The lower abdomen of the air curtain airbag of the existing air curtain type boom sprayer is provided with small holes facing the ground, and the air curtain blown out by the small holes is used to force the small droplets to the crop canopy to reduce the drift of the droplets. Canopy shielding, the deposition of fog droplets on the lower stems and leaves of crops is less, the uniformity of pesticide application is poor, and it cannot resist the interference of natural wind well, especially when the natural wind speed is high, the fog droplet drift is serious and The utilization rate of pesticides is low, and the environmental pollution caused by the loss of liquid medicine is also relatively serious.
