A multi-duct air-supply profiling sprayer

Abstract

The invention discloses a profiling sprayer with multiple air pipes, which includes a profiling frame, an electric control device, a transmission device, an air supply device and a spraying device, and the electric control device controls the profiling frame, the transmission device, the air supply device and the spraying device. The spray device operates, and the transmission device is connected with the air pump, centrifugal fan, and plunger pump to provide power. The spray device uses a plunger pump to atomize the liquid medicine to form a spray. The air delivery device uses a centrifugal fan to generate auxiliary airflow, which passes through the air inlet grid and The control of the adjustable air door realizes the effective adjustment of the wind speed of the air outlet of each air cylinder; the profiling frame includes height, width and angle adjustment devices, so that the adjustment of the height, width and angle of the air cylinder and the nozzle can realize the directional profiling spray, the nozzle Built in the air duct, the liquid medicine is fully mixed with the auxiliary airflow, and under the disturbance of the airflow to the branches and leaves of the canopy, the coverage of the leaves can be effectively improved. The invention improves the deposition rate and uniformity of the distribution of the mist in the canopy, reduces the drift of the liquid medicine, and protects the ecological environment.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to a multi-duct air delivery profiling sprayer. Background technique [0002] Different fruit trees and the same fruit tree have different heights, canopy shapes and thicknesses in different growth periods. At present, there is still a lack of profiling spray devices for this difference between fruit trees at home and abroad. Spraying devices such as the orchard directional misting machine of Shandong Agricultural University are mostly manually adjusted, which limits their application in the field of plant protection. Therefore, the following problems still exist in the application of pesticides for plant protection in orchards in my country: poor pesticide application equipment, low level of pesticide application technology, high labor intensity, serious waste of pesticides, and low utilization rate of pesticides. Therefore, according to the target characteristics o...

[0002] Different fruit trees and the same fruit tree have different heights, canopy shapes and thicknesses in different growth periods. At present, there is still a lack of profiling spray devices for this difference between fruit trees at home and abroad. Spray devices such as the orchard directional mist machine of Shandong Agricultural University are mostly manually adjusted, which limits their application in the field of plant protection

Therefore, the following problems still exist in the application of pesticides for plant protection in orchards in my country: poor pesticide application equipment, low level of pesticide application technology, high labor intensity, serious waste of pesticides, and low utilization rate of pesticides

In terms of air volume adjustment, it is mainly aimed at axial flow sprayers at present. In terms of position and posture changes, there is a mechanical arm structure, but the cost is high and the control is complicated. It is difficult to enter the application field for a period of time.
