Description

Technical Field

[0001] The utility model relates to the field of building accessories, in particular to a herbicide spray anti-drift device used in cotton fields. Background Art

[0002] The use of drones to spray herbicides in cotton fields has the advantages of improving control efficiency, precise spraying, cost saving, high safety and improved control effect. Drone spraying herbicides can greatly improve control efficiency. Traditional weeding methods require a lot of manual input and are relatively inefficient. Drones are efficient and fast and can cover a large area of ​​cotton fields in a short time, thereby effectively controlling weeds.

[0003] In the prior art, when spraying herbicides in the air, the falling herbicides are difficult to spray to the designated area due to air flow resistance during the falling process, resulting in herbicide drift and pollution to the surrounding land. Utility Model Content

[0004] The purpose of the utility model is to solve any one of the problems in the above-mentioned technologies, thereby proposing a herbicide spray anti-drift device for cotton fields.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a herbicide spray anti-drift device for cotton fields, comprising a spraying drone for aerial spraying of pesticides and a spraying rack hung under its fan blade rod, a liquid supply pipeline connected to a feed bin of the spraying drone fixedly arranged in the middle section of the spraying rack, anti-drift nozzles connected to the liquid supply pipeline are arranged on both sides of the spraying rack, a bottom sealing plate is embedded at the bottom of the anti-drift nozzle, a plurality of swirl nozzles are rotatably penetrated in the bottom sealing plate, and a torsion flow channel is arranged in the center of the swirl nozzle.

[0006] Furthermore, the top of the drift nozzle is a funnel-shaped high-pressure spray chamber, the bottom inner wall of the high-pressure spray chamber is embedded with a bottom sealing plate, and the bottom outer wall of the high-pressure spray chamber is embedded with a cylindrical wind shield sleeve.

[0007] Furthermore, the bottom sealing plate is in a truncated cone shape, and a plurality of T-shaped circular through-tube holes which are radially distributed in a circular array from the center to the periphery are arranged on the upper surface of the bottom sealing plate, and the swirl nozzle is rotatably arranged in the through-tube holes.

[0008] Furthermore, the main body of the swirl nozzle is a T-shaped cylinder, a vortex disk is arranged on the upper surface of the T-shaped cylinder of the swirl nozzle, and a penetrating curved and twisted hexagonal notch-shaped twisted flow channel is arranged in the center of the T-shaped cylinder of the swirl nozzle.

[0009] The beneficial effects of the utility model are:

[0010] The herbicide is fed into the high-pressure spray chamber of the anti-drift nozzle through the liquid supply pipeline. The herbicide contacts the vortex disk of the swirl nozzle, pushing the swirl nozzle to rotate. At the same time, the herbicide is sprayed downward at high pressure from the twisting flow channel of the swirl nozzle. The herbicide is given rotational kinetic energy when passing through the curved and twisted twisting flow channel. The rotational kinetic energy of the herbicide when it is sprayed downward makes the herbicide have a good wind-breaking effect, effectively reducing the trajectory deviation of the herbicide sprayed in the air caused by air resistance, so that the weed killer can blast to the designated area more accurately, avoiding the pollution of the surrounding land caused by the drift of the herbicide.

[0019] Please refer to Figures 1 to 7 ;

[0020] The present embodiment provides an anti-drift device for herbicide spraying in cotton fields, comprising a spraying drone 1 for aerial pesticide spraying operations and a spraying frame 2 hung under its fan blade rod, a liquid supply pipeline 3 connected to a feed bin of the spraying drone 1 fixedly arranged in the middle section of the spraying frame 2, anti-drift nozzles 4 connected to the liquid supply pipeline 3 are arranged on both sides of the spraying frame 2, a bottom sealing plate 43 is embedded at the bottom of the anti-drift nozzle 4, a plurality of swirl nozzles 44 are rotatably penetrated in the bottom sealing plate 43, and a twisting flow channel 442 is arranged at the center of the swirl nozzle 44.

[0021] Preferably, the top of the drift nozzle 4 is a funnel-shaped high-pressure spray chamber 41 , a bottom sealing plate 43 is embedded in the inner wall of the bottom of the high-pressure spray chamber 41 , and a cylindrical wind shielding sleeve 42 is embedded in the outer wall of the bottom of the high-pressure spray chamber 41 .

[0022] In a specific embodiment, the wind shielding sleeve 42 provides wind protection for the high-pressure herbicide just sprayed out from the bottom of the drift nozzle 4. When the high-pressure herbicide leaves the area of ​​the wind shielding sleeve 42, it obtains a large kinetic potential energy of falling under the action of gravity acceleration, thereby improving the wind resistance of the high-pressure herbicide when falling, and effectively preventing the high-pressure herbicide from falling and drifting.

[0023] Preferably, the bottom sealing plate 43 is truncated cone-shaped, and a plurality of T-shaped through-tube holes 431 are arranged on the upper surface of the bottom sealing plate 43 and are radially distributed in a circular array from the center to the periphery, and the swirl nozzle 44 is rotatably arranged in the through-tube holes 431 .

[0024] Preferably, the main body of the swirl nozzle 44 is a T-shaped cylinder, a vortex disk 441 is provided on the upper surface of the T-shaped cylinder of the swirl nozzle 44, and a penetrating curved and twisted hexagonal notch-shaped twisted flow channel 442 is provided in the center of the T-shaped cylinder of the swirl nozzle 44.

[0025] When the novel method is used, when the cotton field in the designated area is sprayed with herbicide, first, the feed bin of the spraying drone 1 pumps high-pressure herbicide into the high-pressure spray chamber 41 of the anti-drift nozzle 4 through the liquid supply pipeline 3, and the high-pressure herbicide contacts the vortex disk 441 of the swirl nozzle 44, pushing the swirl nozzle 44 to rotate, and at the same time, the high-pressure herbicide is sprayed downward from the twisting flow channel 442 of the swirl nozzle 44. The herbicide is given rotational kinetic energy when passing through the curved and twisted twisting flow channel 442. The rotational kinetic energy of the herbicide when it is sprayed downward makes the herbicide have a good wind-breaking effect, effectively reducing the trajectory deviation caused by air resistance to the herbicide sprayed in the air, so that the weed killer can blast to the designated area more accurately.
