Abstract

The utility model relates to a spout for air-assisted sprayer, which is designed for solving the problem of wind interference of the traditional spout. The inner and outer nozzles are alternatively sleeved into a whole, the small opening end of the inner nozzle is positioned in the large opening end of the outer nozzle, and the outer side of the outlet of the inner nozzle is sleeved with an annular liquid conveying pipe and a spray head which are communicated with a liquid pump. During spraying operation, the air accelerated by the inner nozzle and the air supplemented from the inner nozzle and the outer nozzle are mixed with the liquid medicine sprayed out from the nozzle, and the mixture is sprayed out after being accelerated again by the outer nozzle. The utility model discloses an in the industry pioneering, the design science, the spout air supply is not disturbed, spouts the medicine range far away, sprays evenly, and the operation effect is ideal. The nozzle has the advantages of simple structure, strong practicability and wide application range, is a primary leap of plant protection mechanical technology, and has great economic and social benefits.

Description

Air-assisted sprayer nozzle

The technical field is as follows:

the utility model relates to a plant protection machinery technical field, specifically say that a spout for air-assisted sprayer.

Background art:

the shower nozzle of traditional air-assisted sprayer generally installs inside the spout, and when the coming wind blows out, the wind direction can be blockked and disturbed because of the structuredness of spout to can reduce the range and the homogeneity of spouting the medicine, directly influence spouts the medicine effect.

Disclosure of Invention

The utility model aims at providing a spout for air-assisted sprayer, this spout can not disturb the trend of the incoming wind, implements the operation of strong and even spouting medicine.

The utility model adopts the technical scheme as follows:

the inner and outer nozzles of the nozzle are both in a round table shape, the large-opening end is an inlet, the small-opening end is an outlet, the inner and outer nozzles are alternately sleeved together through a fixed supporting plate, the small-opening end of the inner nozzle is positioned in the large-opening end of the outer nozzle, the outer side of the outlet of the inner nozzle is sleeved with an annular liquid conveying pipe communicated with a liquid pump, and the pipe is provided with a nozzle communicated with the pipe.

The utility model discloses spout for air-assisted sprayer is the first creation in the industry, and the design science, spout air supply do not receive the interference, spout the medicine range far away, spray evenly, the operation effect ideal. The nozzle has the advantages of simple structure, strong practicability and wide application range, is a primary leap of plant protection mechanical technology, and has great economic and social benefits.

Fig. 3 is a schematic diagram of the wind direction of a nozzle for a wind-driven sprayer.

Detailed Description

The invention will be further described with reference to the accompanying figures 1-3 and examples.

Example (b): the device consists of an inner nozzle 1, a spray head 2, a transfusion tube 3, an outer nozzle 4 and a fixed support plate 5. The inner nozzle 1 and the outer nozzle 4 are both in a round table shape, the large-opening end is an inlet, and the small-opening end is an outlet. The inner nozzle 1 and the outer nozzle 4 are alternately sleeved together through a fixed support plate 5, the small-opening end of the inner nozzle 1 is positioned in the large-opening end of the outer nozzle 4, an annular liquid conveying pipe 3 communicated with a liquid pump is sleeved outside the outlet of the inner nozzle 1, and spray heads 2 communicated with the pipe are uniformly arranged on the pipe.

The working principle of the nozzle is as follows:

during spraying operation, air supply generated by the fan enters from the large-opening end of the inner nozzle 1, is accelerated by the conical inner cavity of the inner nozzle 1 and then rushes out from the small-opening end. With the sudden high-speed airflow entering the large space at the inlet end of the outer nozzle 4, the air pressure is instantly reduced to form a low-pressure area, so that the normal-pressure atmosphere at the annular space between the inner nozzle and the outer nozzle is supplemented into the low-pressure area. Then, the high-speed air supply of the inner nozzle 1 and the supplemented air are mixed with the liquid medicine sprayed by the nozzle 2, and the liquid medicine is sprayed out from the outlet end of the outer nozzle 4 after being accelerated again by the conical inner cavity of the outer nozzle 4.

Claims

1. The utility model provides a spout for air-assisted sprayer which characterized in that:

the inner nozzle (1) and the outer nozzle (4) of the nozzle are both in a round table shape, the large-opening end is an inlet, the small-opening end is an outlet, the inner nozzle (1) and the outer nozzle (4) are alternately sleeved together through a fixed support plate (5), the small-opening end of the inner nozzle (1) is located in the large-opening end of the outer nozzle (4), the outer side of the outlet of the inner nozzle (1) is sleeved with an annular liquid conveying pipe (3) communicated with a liquid pump, and the pipe is evenly provided with a nozzle (2) communicated with the pipe.
