Problems solved by technology

At present, there are the following problems in pesticide spraying in my country: backward technology, heavy fog rain spraying method, low pesticide utilization rate, poor spraying uniformity, poor droplet deposition, waste of liquid medicine, serious environmental pollution and other prominent problems
[0003] At present, the large-scale plant protection machinery in the domestic market has used the air-supply spraying method, but the combination of the liquid flow from the nozzle and the airflow from the fan is complicated, and a combination device of the nozzle and the air-supply device has not yet been formed.

Embodiment 1

[0021] The high-pressure medicine liquid enters the nozzle 5 through the infusion tube 8. Since the infusion tube 8 and the nozzle 5 are connected by a special sealing nut and there is a sealing gasket inside, there will be no leakage; The fixed seat 6 is fixed on the duckbill air outlet 1, the inclination angle between it and the duckbill air outlet is 8°, and the extension distance is 20mm; the high-speed airflow passes through the air inlet 9, which is 80mm in outer diameter, 3mm in thickness, and 50mm in length. The cylinder enters the duckbill air outlet 1, and its large mouth end is 50mm wide, 170mm long, and the two ends are arc-shaped oblate outlets; using the deflector 3, it is 60mm wide, 170mm high, and the two ends are The iron plate with a smooth arc and a thickness of 2mm makes the air flow evenly distributed and blows out of the duckbill air outlet 1. Since the duckbill air outlet 1 is oblate, the blown airflow is fan-shaped, so the spray width can be increased; b...

Abstract

The invention relates to a duckbilled air-feeding type combined sprayer which comprises a duckbilled air outlet, an air blocking board, a flow guiding board, a sprayer body, an infusion pipe and an air inlet. High-pressure liquid pesticide enters the sprayer body through the infusion pipe, the sprayer body is fixed on the outer side of the duckbilled air outlet, high-speed air flow sprayed out by a fan enters a duckbilled part through the air inlet and blown out from the duckbilled air outlet uniformly through the flow guiding board to be mixed with liquid flow sprayed out from the sprayer body, and the air blocking board is fixed on the outer side of the duckbilled air outlet to reduce the influence on the liquid flow caused by natural air. The duckbilled air-feeding type combined sprayer atomizes the liquid pesticide secondarily through the air flow blown out from the duckbilled air outlet to form finer fogdrop which is blown to an object by the air flow, mist can be evenly adhered onto leaf back, leaf surface and the around portion of crops due to the stirring effect of the air flow on branches and leaves, pesticide receiving amount and evenly distribution can be improved. The duckbilled air-feeding type combined sprayer improves the permeability of the fogdrop on plants and the pesticide utilization rate, reduces running off of liquid pesticide and protects the ecological environment.

Description

(1) Technical field [0001] The invention relates to a duckbill air-supply combined nozzle, which belongs to the technical field of atomization devices. (2) Background technology [0002] my country is a large agricultural production country. Whether it is food crops such as wheat and corn, or economic crops such as apples and grapes, plant protection is required, and pesticide spraying is an indispensable work. At present, my country's pesticide spraying has the following problems: backward technology, heavy fog rain spraying method, low pesticide utilization rate, poor spraying uniformity, poor droplet deposition, waste of liquid medicine, serious environmental pollution and other outstanding problems. However, modern agricultural production technology requires that it is best to form fine mist droplets for the sprayed liquid, which is called mist, so that the spray droplets can penetrate the plants well, improve the pesticide acceptance rate and uniform distribution, and r...
