Description

Technical Field

[0001] The invention relates to the technical field of aircraft pesticide spreaders, and in particular to an aircraft pesticide spreader for plant pest control with a medicine box to prevent residue. Background Art

[0002] Flying pesticide spreaders, also known as unmanned aerial vehicles, are unmanned aircraft used for agricultural and forestry plant protection operations. With the rapid development of drone technology, agricultural drones are not only used for pesticide spraying, but also for spreading fertilizers, seeds, feed and other tasks. They can meet the diverse needs of farmers and improve production efficiency.

[0003] Most machines on the market use water pumps to spray internal liquid medicine during use, which increases the energy consumption of the equipment and adds too much power equipment, affecting the balance of the equipment's flight, which is not conducive to the equipment's own safety protection. Existing agricultural spraying drones use water pumps to spray internal liquid medicine during use, which increases the energy consumption of the equipment and adds too much power equipment, affecting the balance of the equipment's flight, which is not conducive to the equipment's own safety protection.

[0004] In order to overcome the above defects, the prior art (application number: CN112660389A, Chinese patent with application date of 2023-05-23) discloses an agricultural pesticide-spreading drone, including a drone body, the four corners of the top of the drone body are connected with flying wings, and the middle position of the bottom of the drone body is movably connected with a pesticide-spreading mechanism; the pesticide-spreading mechanism includes a positioning mechanism, the side of the positioning mechanism away from the drone body is movably connected with an inertial cartridge, the bottom of the inner surface of the inertial cartridge is located on the left side of the positioning mechanism and is movably connected with a spraying mechanism, the inner surface of the inertial cartridge is located on the upper middle position of the right side of the positioning mechanism and is movably connected with a card block, and the top of the positioning mechanism is movably connected with the drone body. The present invention relates to the field of drone technology. The inertia generated by the mass of the liquid medicine itself in motion is used to trigger the equipment, avoid adding a secondary power source to the drone, prevent internal vibration from affecting the balance of the drone, reduce the energy consumption of the equipment itself, and improve the drone service life.

[0005] Although the existing technology can solve the above problems, for long-distance pesticide delivery and spraying, the medicine filled inside will precipitate in the water tank as the movement trajectory gradually stabilizes, resulting in different pesticide content received in different areas, so that the insect pest situation will not be effectively suppressed. The effect will only be more significant in the spraying area with higher pesticide concentration in the second half of the spraying. In addition, the existing spraying method is not convenient and uniform enough, which affects the insect control effect of crops. Summary of the invention

The lower opening of the medicine storage box is of a semicircular design, and a first inner groove is provided on the outer surface of the passive gear. A water supply tank is installed on the outer surface of the passive gear, and the water supply tank is of a hollow design.

[0010] Furthermore, a spray pipe is installed on the outer surface of the water tank, and the water tank and the spray pipe are designed to be internally connected. A movable rotating rod is installed on the outer surface of the spray pipe, and the spray pipe is rotatably installed inside the movable rotating rod. A sliding groove is installed on the outer surface of the fixed integrated plate, and the upper end of the movable rotating rod is slidably installed inside the sliding groove.

[0011] Furthermore, a feed port is installed on the back of the medicine storage box, and the medicine storage box is connected to the inside of the feed port, a support fixing frame is installed above the connecting fixed plate, and a driving motor is installed inside the support fixing frame, the driving motor is fixedly installed inside the support fixing frame, and a rotating resistance rod is installed at the upper output end of the driving motor, and a buffer support frame is installed on the outer surface of the fixed integrated plate.

[0012] Furthermore, a semicircular resistance block is installed at the end of the rotating resistance rod, and the rotation trajectory of the semicircular resistance block contacts the U-shaped resistance frame, a driving rod is installed on the lower surface of the U-shaped resistance frame, and a stirring rod is installed on the outer surface of the driving rod, a return spring is installed on the outer surface of the stirring rod, and a limiting sliding plate is installed at the front end of the return spring, the stirring rod is slidably installed inside the limiting sliding plate, and a stirring sliding plate is installed at the front end of the stirring rod.

[0013] Furthermore, the UAV flight propellers are installed in four groups equidistantly about the center point of the protective top cover, and the connecting and fixing plates are installed in two groups symmetrically about the center point of the protective top cover, and the connecting and fixing plates and the mounting support plate are designed as an integrated whole, and the medicine storage tanks are installed in two groups symmetrically about the center point of the mounting support plate.

[0014] Furthermore, the inner surface of the U-shaped resistance frame contacts the outer surface of the semicircular resistance block to form a sliding structure, and the rotating resistance rod and the semicircular resistance block are integrally designed, and the driving rod and the U-shaped resistance frame are integrally designed, and the inner part of the limiting sliding plate contacts the outer surface of the stirring rod to form a sliding structure.

[0015] Furthermore, the outer surface of the rotating gear contacts the outer surface of the passive gear to form a meshing structure, and the lower end opening of the medicine storage box corresponds to the hollow opening of the water delivery box, and the rotating support rod and the passive gear are designed as an integral whole, and the rotating support rod and the passive gear are installed in two groups symmetrically about the center point of the mounting support plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: when it is necessary to carry out pest prevention work on crops or green plants, the UAV flight propeller is first started to make the whole device fly in the air, and then the driving motor is started to rotate by remote control. The rotation of the driving motor drives the semicircular resistance block to rotate in a circle through the external rotating resistance rod. The movement trajectory of the semicircular resistance block contacts the U-shaped resistance frame and because the U-shaped resistance frame is a semicircular design, the U-shaped resistance frame is driven to slide. As the U-shaped resistance frame moves, the stirring rod passes through the limiting sliding plate to make the stirring sliding plate slide back and forth inside the medicine storage box. Such a design allows the medicine stored in the medicine storage box to be continuously stirred without precipitation, and the residual medicine can be completely discharged from the inside. Furthermore, when the driving motor is started, the driving motor drives the rotating gear to rotate synchronously, and the rotation of the rotating gear drives the passive gears that are in contact with each other. As the passive gear rotates at the opening of the medicine storage tank, the semicircular opening of the medicine storage tank overlaps with the first inner groove opened on the surface of the passive gear, so that the medicine inside the medicine storage tank flows into the water delivery tank, and the water delivery tank then spreads the medicine inside through the spray pipe over a large area to achieve the effect of pest control. Furthermore, when facing green plants or farmlands of different areas or sowing requirements, when angle adjustment is required, the movable rotating rod is slid upward or downward along the inside of the sliding groove. Since the spray pipe is rotatably installed in the movable rotating rod, the spray pipe is driven to swing at different angles on the side of the water tank. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The outer surface of the protective top cover 1 is installed with a UAV flight paddle 2, and the protective top cover 1 and the UAV flight paddle 2 are fixedly installed, the left and right sides of the protective top cover 1 are installed with a connecting fixing plate 3, and the outer surface of the connecting fixing plate 3 is installed with a fixed integrated plate 26, the connecting fixing plate 3 is fixedly installed on the lower surface of the protective top cover 1, and the lower surface of the connecting fixing plate 3 is installed with a mounting support plate 4, and the fixed integrated plate 26 is fixedly installed on the outer surface of the connecting fixing plate 3, the lower surface of the connecting fixing plate 3 is installed with a mounting support plate 4, and a sliding elastic mechanism for transmitting the stirring sliding plate 27 is installed above the mounting support plate 4, the sliding elastic mechanism includes a medicine storage tank 5, and the medicine storage tank 5 is fixedly installed on the upper surface of the mounting support plate 4; A water delivery box 11 is installed below the mounting support plate 4 , and a meshing transmission mechanism for internally penetrating the spray pipe 9 is installed inside the water delivery box 11 .

[0023] like Figure 2 , Figure 4 , Figure 5 , Fig. 9The technical solution shown, in order to solve the problem that long-term steady movement causes precipitation of medicine, resulting in uneven spreading concentration and poor pest control effect, discloses: a feed port 12 is installed on the back of the medicine storage box 5, and the medicine storage box 5 is connected to the inside of the feed port 12, a support fixing frame 21 is installed above the connecting fixed plate 3, and a driving motor 19 is installed inside the support fixing frame 21, the driving motor 19 is fixedly installed inside the support fixing frame 21, and a rotating resistance rod 10 is installed at the upper output end of the driving motor 19, and a buffer support frame 6 is installed on the outer surface of the fixed integrated plate 26, a semicircular resistance block 20 is installed at the end of the rotating resistance rod 10, and the rotation trajectory of the semicircular resistance block 20 contacts the U-shaped resistance frame 18, a driving rod 17 is installed on the lower surface of the U-shaped resistance frame 18, and a stirring rod 15 is installed on the outer surface of the driving rod 17, and the outer surface of the stirring rod 15 A return spring 16 is installed on the surface, and a limited sliding plate 14 is installed at the front end of the return spring 16, a stirring rod 15 is slidably installed inside the limited sliding plate 14, and a stirring sliding plate 27 is installed at the front end of the stirring rod 15, four groups of UAV flight paddles 2 are installed equidistantly about the center point of the protective top cover 1, and two groups of connecting and fixing plates 3 are installed symmetrically about the center point of the protective top cover 1, and the connecting and fixing plates 3 and the mounting support plate 4 are integrated into one design, and two groups of medicine storage boxes 5 are installed symmetrically about the center point of the mounting support plate 4, the inner surface of the U-shaped resistance frame 18 contacts the outer surface of the semicircular resistance block 20 to form a sliding structure, and the rotating resistance rod 10 and the semicircular resistance block 20 are integrated into one design, and the driving rod 17 and the U-shaped resistance frame 18 are integrated into one design, and the inside of the limited sliding plate 14 contacts the outer surface of the stirring rod 15 to form a sliding structure.

[0024] When it is necessary to carry out pest control work on green plants or crops, first start the four sets of drone flight propellers 2 installed on the outer surface of the protective top cover 1, so that the drone flight propellers 2 drive the entire mechanism in the air for easy sowing work. When reaching a suitable working height, start the drive motor 19 fixedly installed inside the support bracket 21 again to work. After the drive motor 19 is started, the rotating resistance rod 10 fixedly installed on the outer surface of the upper output end is driven to produce circular rotation. Since the semicircular resistance block 20 and the rotating resistance rod 10 are of an integrated design, the semicircular resistance block 20 rotates synchronously. During the rotation of the semicircular resistance block 20, it contacts the U-shaped resistance frame 18. Since the U-shaped resistance frame 18 is of a semicircular design, the U-shaped resistance frame 18 is driven backwards under the resistance of the semicircular resistance block 20. In addition, the driving rod 17 fixedly installed on the outer surface of the U-shaped resistance frame 18 slides inside the sliding inner groove 13 opened at the corresponding position of the upper surface of the medicine storage box 5. When the driving rod 17 slides inside the medicine storage box 5, the stirring rods 15 fixedly installed at the front and rear ends of the driving rod 17 drive the fixedly installed stirring sliding plate 27 to move forward. When the stirring rod 15 slides along the inside of the limiting sliding plate 14, the return spring 16 nested on the outer surface of the stirring rod 15 resists against the outer surface of the limiting sliding plate 14 and is compressed during the resistance process. During the sliding process of the stirring sliding plate 27 on the bottom surface of the inner surface of the medicine storage box 5, the medicine stored in the medicine storage box 5 is continuously stirred so that the concentration of the medicine during the spreading process remains consistent and there will be no uneven effects.

[0025] like Figure 1 , Figure 3 , Figure 6 , Figure 7 , Figure 8The technical solution shown, in order to solve the problem that the prior art design of medicine spreading is too complicated and the angle is not easy to adjust, making the spreading range uncontrollable, discloses: the meshing transmission mechanism includes a rotating gear 22, and the rotating gear 22 is fixedly mounted on the lower surface of the driving motor 19, the rotating gear 22 is rotatably mounted on the lower surface of the mounting support plate 4, and the rotating trajectory of the rotating gear 22 contacts the passive gear 24, a rotating support rod 23 is installed at the center position of the passive gear 24, and the rotating support rod 23 is rotatably mounted inside the medicine storage tank 5, the rotating support rod 23 and the passive gear 24 are of an integrated design, and the passive gear 24 is located at the lower end opening of the medicine storage tank 5, the lower end opening of the medicine storage tank 5 is of a semicircular design, and the outer surface of the passive gear 24 is provided with a first inner groove 25, the outer surface of the passive gear 24 is provided with a water delivery tank 11, and the water delivery tank 11 is of a hollow design, and the outer surface of the water delivery tank 11 is provided with a spray pipe 9, The water tank 11 and the spray pipe 9 are designed to be internally connected. A movable rotating rod 8 is installed on the outer surface of the spray pipe 9, and the spray pipe 9 is rotatably installed inside the movable rotating rod 8. A sliding groove 7 is installed on the outer surface of the fixed integrated plate 26, and the upper end of the movable rotating rod 8 is slidably installed inside the sliding groove 7. The outer surface of the rotating gear 22 contacts the outer surface of the passive gear 24 to form a meshing structure, and the lower end opening of the medicine storage tank 5 corresponds to the hollow opening of the water tank 11. The rotating support rod 23 and the passive gear 24 are designed as an integrated unit, and two groups of the rotating support rod 23 and the passive gear 24 are symmetrically installed about the center point of the mounting support plate 4. The spray pipe 9 is symmetrically installed about the center point of the water tank 11 in two groups, and the spray pipe 9 and the water tank 11 are symmetrically installed about the center point of the mounting support plate 4 in two groups, and the inner surface of the sliding groove 7 contacts the outer surface of the upper end of the movable rotating rod 8 to form a sliding structure.

[0026] When the driving motor 19 is working, the rotating gear 22 fixedly installed below the driving motor 19 is driven to rotate in a circle. Since the rotating gear 22 is rotatably installed on the lower surface of the mounting support plate 4, the rotating gear 22 continuously rotates in place. During the rotation of the rotating gear 22, the passive gears 24 that are in contact with each other on the left and right sides of the rotating gear 22 are driven to produce meshing motion. While the passive gear 24 produces meshing motion, since the center position of the passive gear 24 is fixedly connected to the rotating support rod 23, and since the rotating support rod 23 is rotatably installed inside the medicine storage box 5, the passive gear 24 rotates closely in the lower end opening of the medicine storage box 5. Since the lower end opening of the medicine storage box 5 is semicircular in design, and the first inner groove 25 provided on the outer surface of the passive gear 24 is also semicircular in distribution, during the rotation of the passive gear 24, the first inner groove 25 is formed on the outer surface of the passive gear 24. The inner groove 25 will overlap with the lower end opening of the medicine storage box 5 to achieve internal communication between the medicine storage box 5 and the water delivery box 11. Since the lower end opening of the medicine storage box 5 corresponds to the opening of the water delivery box 11, the medicine stored in the medicine storage box 5 enters the water delivery box 11. Since the spray pipe 9 is connected to the inside of the water delivery box 11, the spray pipe 9 transmits the medicine again to complete a larger range of discharge. When the sowing area needs to be controlled in response to different sowing environments, the movable rotating rod 8 is slid upward along the inside of the sliding groove 7. Since the spray pipe 9 is rotatably installed inside the movable rotating rod 8, the spray pipe 9 swings up and down on the side of the medicine storage box 5 as the movable rotating rod 8 slides until it stops swinging at a suitable position. When not in use, the buffer support frame 6 fixed on the outer surface of the fixed integrated plate 26 can be used to support the entire equipment.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
