Description

Technical Field

[0001] This invention relates to the field of agricultural pest control technology, specifically to a pesticide application device for controlling cotton pests and diseases. Background Technology

[0002] Cotton is a widely cultivated economic crop in my country, and cotton cultivation is now largely mechanized. Spider mites and mites are two of the most common pests, often attaching themselves to the undersides of cotton leaves. Large machinery spraying pesticides is ineffective in controlling these pests, requiring cotton farmers to manually spray pesticides bit by bit on the undersides of the cotton plants – a labor-intensive process. However, given the large cotton-growing area, manual spraying is extremely costly. While drones are currently used for pesticide spraying, they only spray the surface of the cotton plant, failing to reach the leaves and thus having little effect on the pests on the undersides. The use of a blower in conjunction with a spraying mechanism to blow up cotton leaves during pesticide spraying allows for spraying on the underside of the leaves. However, using a blower for pest and disease control during the pollen season can damage the cotton crop, reducing yield and directly impacting economic returns. Furthermore, most large-scale mechanical pesticide sprayers have fixed nozzles that cannot be adjusted for swinging or varying amplitude. Additionally, the spray booms of commonly used spraying devices are also fixed. Since cotton crops vary in height at different growth stages, adjusting the nozzles according to the cotton's height during these stages would be far more effective in controlling pests and diseases.

[0003] To address the aforementioned problems, the inventors have proposed a pesticide application device for controlling cotton diseases and pests. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. This invention uses a synchronization mechanism and a swing mechanism. The rotation of the motor of the synchronization mechanism drives the swing mechanism to swing, so that the atomizing nozzle swings back and forth to achieve fan-shaped spraying and expand the spraying area. The synchronization mechanism uses a ring frame to position the swing mechanism under the cotton crop leaves. The nozzle of the atomizing nozzle is set upward, so that the pesticide is sprayed from bottom to top. It is mainly for the prevention and control of diseases and pests on the lower part of cotton leaves.

[0016] 2. This invention uses a swing mechanism. The electric telescopic rod extends and drives the sliding frame to move. The movement of the sliding frame drives the guide frame to move. The guide frame drives the rotating frame to move within the arc-shaped frame. By adjusting the position of the rotating frame within the arc-shaped frame, the amplitude of the rotating frame's rotation can be adjusted, thereby adjusting the swing amplitude of the swing rod. Adjusting the swing amplitude of the spraying swing rod according to the actual situation of cotton crop planting can effectively improve the efficiency of pesticide use.

[0017] 3. The present invention uses a lifting mechanism. The rotation of the second rotating shaft drives the rotation of the first rotating shaft, which in turn drives the synchronous wheel transmission group to rotate. The rotation of the synchronous wheel transmission group drives the lifting frame to move up and down within the lifting frame. The lifting frame moves up and down, which in turn drives the lifting plate to move up and down, thereby adjusting the height of the spray bar. This adjustment can be made according to the growth height of cotton crops at different stages, which can increase the applicability of the spraying device for controlling cotton diseases and pests.

[0047] Working principle: First, move the device next to the cotton planting area. Manually move the first moving frame 608 and the second moving frame 801 to the corresponding positions according to the cotton planting spacing. Manually rotate the rotating wheel 310. The rotation of the rotating wheel 310 drives the first worm gear 309 to rotate, which in turn drives the first worm wheel 308 to rotate. The rotation of the first worm wheel 308 drives the second rotating shaft 307 to rotate, which in turn drives the second bevel gear 306 to rotate. The rotation of the second bevel gear 306 drives the meshing first bevel gear 305 to rotate, which in turn drives the first rotating shaft 304 to rotate. The rotation of the first rotating shaft 304 drives the synchronous gear transmission group 303 to rotate. The rotation of group 303 drives the meshing fixed gear 302 to move up and down. The movement of the fixed gear 302 drives the lifting frame 301 to move up and down within the lifting frame 2. The movement of the lifting frame 301 drives the lifting plate 4 to move up and down. The lifting plate 4 moves up and down under the guidance of the guide rod 201. The movement of the lifting plate 4 drives the extension mechanism 5 to move up and down. The extension mechanism 5 is adjusted to an appropriate height according to the growth status of the cotton crop by the lifting mechanism 3. The control starts the rotating motor 601. The drive end of the rotating motor 601 rotates, which drives the synchronous shaft 603 to rotate through the belt pulley transmission group 602. The rotation of the synchronous shaft 603 drives the annular frame 604 to rotate. The rotation of the annular frame 604 drives the second worm gear 605 to rotate. The rotation of the second worm gear 605 drives the... The second worm gear 606 rotates, driving the third rotating shaft 607 to rotate. The third rotating shaft 607 rotates, driving the third bevel gear 610 to rotate. The third bevel gear 610 rotates, driving the meshing fourth bevel gear 611 to rotate. The fourth bevel gear 611 rotates, driving the fourth rotating shaft 702 to rotate. The fourth rotating shaft 702 rotates, driving the arc frame 706 to rotate. The arc frame 706 rotates, driving the rotating frame 708 to rotate. The rotating frame 708 rotates, driving the swing frame 710 to swing. The swing frame 710 swings, driving the rotating shaft 711 to reciprocate. The rotating shaft 711 rotates, driving the swing rod 712 to perform a fan-shaped reciprocating swing. The swing rod 712 swings, driving the atomizing nozzle 9 to swing, thus causing the atomizing nozzle 9 to swing. The dynamic movement expands the spraying range. When the oscillation amplitude of the atomizing nozzle 9 needs adjustment, the electric telescopic rod 713 is activated. The drive end of the electric telescopic rod 713 drives the circular plate 714 to extend and retract. The circular plate 714 drives the sliding frame 703 to move on the fourth rotating shaft 702. When the sliding frame 703 moves forward, it drives the guide frame 704 to move upward around the second fixed shaft 707 via the first fixed shaft 705. The upward movement of the guide frame 704 drives the third fixed shaft 709 to move upward in the arc-shaped frame 706. The movement of the third fixed shaft 709 drives one end of the rotating frame 708 to move upward. The movement of the rotating frame 708 increases the rotation amplitude of the rotating frame 708. The increased amplitude of the rotating frame 708 increases the oscillation amplitude of the swing frame 710.The increased swing amplitude of the swing frame 710 drives the swing arm 712 to swing more, thereby increasing the swing amplitude of the atomizing nozzle 9. A larger swing amplitude results in a wider spraying area. After adjusting the swing amplitude of the atomizing nozzle 9, the nozzle 9 is connected via a flexible hose, which is connected to a pressure water pump and a pesticide tank. The pressure water pump is turned on, and the mixed pesticide is delivered to each atomizing nozzle 9 via the hose. The pesticide is then atomized and sprayed through the nozzles. Controlling the rotation speed of the rotating motor 601 controls the swing rate of the swing mechanism 7, ultimately moving the cotton pest and disease control device forward to spray the cotton field.
