Description

Technical Field

[0001] The invention relates to the technical field of plant protection UAVs, in particular to an inclined and dislocated windproof pesticide spreading plant protection UAV. Background Art

[0002] In the field of plant protection drones, traditional spraying technology has some significant defects. First, the spray pipes of many existing drones are set in the same direction as the wind output direction of the propeller, which makes the sprayed medicine easily affected by the wind pressure generated by the rotation of the propeller, and the liquid medicine is easily blown away, thereby reducing the effectiveness of the spraying. Secondly, due to the wind force generated by the propeller, the sprayed liquid medicine is difficult to quickly escape from its agitation range, which further affects the uniformity and coverage of the spraying.

[0003] In addition, the spray pipe design of existing drones is often relatively simple and lacks sufficient adjustment mechanisms to optimize the spraying effect. This results in that in actual applications, the distance between the spray end of the spray pipe and the propeller is fixed and cannot be adjusted according to actual spraying needs, limiting the spraying efficiency and effect. At the same time, the design of the liquid storage box of some drones is not reasonable enough, and the stability and safety of the liquid storage box during flight are difficult to guarantee, which may affect the flight stability of the drone due to shaking.

[0004] Finally, in the prior art, the spraying pipe of the drone is easily damaged and deformed during transportation, and the spraying rod is long, which makes transportation inconvenient. These problems not only increase the maintenance cost, but also limit the widespread application of drones in actual agricultural plant protection operations. Summary of the invention

The limit plates are arranged in pairs as a group, and the two limit plates are arranged horizontally opposite to each other. When the UAV flies to the specified position, the hydraulic rod is driven to work. When the hydraulic rod starts to work, it will push the driving block to move inside the outer frame toward the rear of the body.

[0015] The present invention provides a tilted and staggered windproof pesticide spraying plant protection drone, which has the following beneficial effects: 1. This tilted and dislocated windproof pesticide-spraying plant protection drone sets the spraying pipe parallel to the fuselage, so that the direction of the medicine sprayed by the spraying pipe and the direction of the wind pressure generated by the rotation of the propeller are perpendicular to each other, which greatly reduces the problem of the liquid medicine being blown away by the propeller and affecting the effectiveness of the spraying. At the same time, the drone will fly forward slowly when working. By spraying the liquid medicine behind the fuselage, the sprayed liquid medicine can quickly escape from the agitation range of the propeller, thereby further improving the effectiveness of the spraying liquid medicine.

[0016] 2. The tilted staggered windproof pesticide spraying plant protection drone drives the spraying pipe to move along the sliding pipe to the outside of the outer frame through the connecting frame, thereby further increasing the distance between the spraying end of the spraying pipe and the propeller, that is, further reducing the problem that the liquid medicine may be affected by the wind force of the propeller during the spraying process. At the same time, when the spraying pipe is moving, due to the limiting effect of the limiting ball, the spraying pipe will only move along the side of the guide plate, and the guide plate is arranged in an arc shape, so during the movement of the spraying pipe, the spraying end will rotate due to the action of the guide plate. At the same time, the squeezing force of the elastic telescopic rod causes the two spraying pipes to finally unfold in an eight-shaped shape, which can not only greatly reduce the influence of the propeller wind force, but also increase the spraying area of ​​the outer ends of the two spraying pipes, greatly improving the spraying efficiency of the drone. When the spraying is completed, the hydraulic rod is driven to reset, and at this time, the two spraying pipes will also be reset and retracted and move to the inside of the outer frame, thereby avoiding the problem that the existing drone uses a long spraying rod to increase the spraying area, which causes inconvenience in transportation, and the spraying pipe is easily damaged and deformed during transportation.

[0017] 3. For this inclined and staggered windproof pesticide-spreading plant protection drone, when the liquid in the liquid storage box is injected, the card block is slid to both sides, so that the support force between the support frame and the matching plate is lost, and then the support frame slides down close to the matching plate under the action of the gravity of the liquid storage box, and finally the rotating roller fits in the limit groove on the matching plate, making it difficult for the rotating roller to rotate, thereby ensuring the stability of the liquid storage box during the operation of the drone, and preventing the liquid storage box from shaking in the outer frame and affecting the flight stability of the drone. When the liquid is sprayed, the gravity of the liquid storage box itself is greatly reduced. At this time, the support frame will be reset under the action of elastic force, so that the rotating roller can continue to rotate, so that the liquid storage box can be taken out more conveniently after the spraying is completed, which greatly saves manpower and material resources. At the same time, by automatically fixing and loosening the liquid storage box, the applicability of the drone is also greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] First embodiment: Figures 1 to 8 As shown, the present invention provides a technical solution: an inclined staggered wind-proof pesticide spraying plant protection drone, comprising a body 1, a connecting rod 2 is fixedly connected to the outer surface of the body 1, a propeller 3 is fixedly connected to the end of the connecting rod 2 away from the body 1, four propellers 3 are symmetrically arranged, and a bracket 4 is symmetrically fixedly connected to the bottom side of the body 1, and further comprising: A spray unit 5, which is fixedly connected to the bottom surface of the body 1 and is also arranged on the inner side of the bracket 4, and is used to store liquid medicine; The regulating unit 6 is fixedly installed inside the spraying unit 5. The regulating unit 6 is used to cooperate with the spraying unit 5 and is also used to regulate the spraying of the liquid medicine. The spray unit 5 includes an outer frame 51, the cross-section of the outer frame 51 is set to be convex, the interior of the outer frame 51 is set to be hollow, the outer surfaces of both sides of the outer frame 51 are fixedly connected with stabilizing plates 52, and a plurality of stabilizing plates 52 are arranged at fixed intervals. A liquid storage box 53 is arranged inside the outer frame 51, and a hose 54 is fixedly connected to the inner surface of the bottom of the liquid storage box 53. The hose 54 is made of rubber material. Two hoses 54 are symmetrically arranged inside the outer frame 51, and one end of the hose 54 away from the liquid storage box 53 is fixedly connected with a spray pipe 55. The spray pipe 55 is made of metal material. Two spray pipes 55 are arranged, and the two spray pipes 55 are arranged parallel to the bottom surface of the outer frame 51. The end of the spray pipe 55 away from the hose 54 is arranged on the outside of the bottom of the outer frame 51.

[0022] During operation, when it is necessary to spray pesticides on crops, liquid medicine can be injected into the liquid storage box 53. After the injection of the liquid medicine is completed, the propeller 3 can be driven to rotate and drive the outer frame 51 to move to the specified position. At this time, the liquid medicine is extracted from the liquid storage box 53 through the hose 54 and injected into the spray pipe 55, and the liquid medicine is sprayed on the crops through the spray pipe 55 to complete the spraying of the liquid medicine. By arranging the spray pipe 55 in parallel with the body 1, the direction of the medicine sprayed by the spray pipe 55 can be perpendicular to the direction of the wind pressure generated by the rotation of the propeller 3, which greatly reduces the problem of the liquid medicine being blown away by the propeller 3 and affecting the effectiveness of the spraying. At the same time, the drone will fly forward slowly when working. By spraying the liquid medicine behind the body 1, the sprayed liquid medicine can quickly leave the agitation range of the propeller 3, thereby further improving the effectiveness of the spraying liquid medicine.

[0023] Second embodiment: Figures 1 to 8 As shown, the adjustment unit 6 includes a connecting frame 61, which is rotatably connected to the outer surface of the spray pipe 55 close to the hose 54, and the outer surface of the connecting frame 61 away from the spray pipe 55 is fixedly connected to an elastic telescopic rod 62, and the elastic telescopic rod 62 is bidirectionally arranged. The middle outer surface of the elastic telescopic rod 62 is fixedly connected to a driving block 63, and the driving block 63 is arranged below the liquid storage box 53.

[0024] A hydraulic rod 64 is fixedly connected to the outer surface of the driving block 63 . One end of the hydraulic rod 64 away from the driving block 63 is fixedly connected to the inner side surface of the outer frame 51 . The hydraulic rod 64 and the liquid storage box 53 are arranged to be parallel to each other.

[0025] A guide plate 65 is provided on the side of the spray pipe 55 away from the connecting frame 61. The guide plate 65 is arranged in an arc shape. Two guide plates 65 are symmetrically arranged below the liquid storage box 53. A slide groove 66 is opened inside the guide plate 65. The cross-section of the slide groove 66 is arranged in a circular shape. The slide groove 66 is internally slidably connected to a limiting ball 67. The limiting ball 67 is fixedly connected to the outer surface of the spray pipe 55 on the side away from the connecting frame 61.

[0026] A sliding tube 68 is slidably sleeved on the outer surface of one end of the spraying tube 55 away from the connecting frame 61 , and a rotating rod 69 is symmetrically fixedly connected to the upper and lower outer surfaces of the sliding tube 68 . The end of the rotating rod 69 away from the sliding tube 68 passes through a rotatably connected limiting ring 610 .

[0027] The limiting ring 610 is concentrically arranged with the sliding tube 68 . The diameter of the limiting ring 610 is larger than that of the sliding rod. The inner surface of the limiting ring 610 is symmetrically fixedly connected with a rubber ring 611 . The inner side of the rubber ring 611 is fixedly connected to the outer surface of the sliding tube 68 .

[0028] The outer surfaces on both sides of the limiting ring 610 are horizontally slidably connected to the limiting plates 612, which are respectively fixedly connected to the inner and outer surfaces of the bottom of the outer frame 51. The limiting plates 612 are arranged in pairs as a group, and the two limiting plates 612 are arranged horizontally opposite to each other.

[0029] During operation, when the drone flies to the designated position, the hydraulic rod 64 is driven to work. When the hydraulic rod 64 starts to work, it will push the driving block 63 to move inside the outer frame 51 toward the rear of the body 1. The driving block 63 is fixedly connected to the elastic telescopic rod 62, so when the driving block 63 moves, the elastic telescopic rod 62 will also move, and then drive the spraying pipe 55 to move along the sliding pipe 68 to the outside of the outer frame 51 through the connecting frame 61, thereby further increasing the distance between the spraying end of the spraying pipe 55 and the propeller 3, that is, further reducing the problem that the liquid medicine may be affected by the wind force of the propeller 3 during the spraying process. At the same time, when the spraying pipe 55 is moving, due to the limiting effect of the limiting ball 67, the spraying pipe 55 will only move along the guide The side of the plate 65 moves, and the guide plate 65 is set to be arc-shaped, so during the movement of the spraying tube 55, the spraying end will rotate due to the action of the guide plate 65, and at the same time, the squeezing force of the elastic telescopic rod 62 causes the two spraying tubes 55 to finally unfold in an eight-shaped shape, which can not only greatly reduce the impact of the wind force of the propeller 3, but also increase the spraying area of ​​the outer ends of the two spraying tubes 55, greatly improving the spraying efficiency of the UAV. When the spraying is completed, the hydraulic rod 64 is driven to reset. At this time, the two spraying tubes 55 will also be reset, retracted and moved inside the outer frame 51, thereby avoiding the problem that the existing UAV uses a long spraying rod to increase the spraying area, which causes inconvenience in transportation, and the spraying tube 55 is easily damaged and deformed during transportation.

[0030] The third embodiment: Figures 1 to 8 As shown, the inner surfaces of both sides of the outer frame 51 are symmetrically and elastically connected with a support frame 613 in an upward and downward sliding manner. The support frame 613 is arranged below the liquid storage box 53. The support frame 613 and the liquid storage box 53 are relatively parallel. The upper surface of the support frame 613 is penetrated by a mounting groove 614. The inner surface of the mounting groove 614 is evenly rotatably connected with a rotating roller 615. The rotating roller 615 is fitted on the bottom surface of the liquid storage box 53.

[0031] A matching plate 616 is provided on the side of the support frame 613 away from the liquid storage box 53, and a limiting groove 617 is evenly provided on the surface of the matching plate 616 close to the support frame 613. The limiting groove 617 is set to a semi-cylindrical shape, and the diameter of the limiting groove 617 is the same as the diameter of the rotating roller 615. A clamping block 618 is provided between the support frame 613 and the matching plate 616, and the upper and lower surfaces of the clamping block 618 are respectively in contact with the bottom surface of the support frame 613 and the upper surface of the matching plate 616, and the clamping block 618 is symmetrically and horizontally slidably connected to the inner surfaces of both sides of the outer frame 51.

[0032] During operation, after the injection of the liquid in the liquid storage box 53 is completed, the block 618 is slid to both sides, so that the support force between the support frame 613 and the matching plate 616 is lost, and then the support frame 613 slides down and approaches the matching plate 616 under the action of the gravity of the liquid storage box 53, and finally the rotating roller 615 fits in the limiting groove 617 on the matching plate 616, making it difficult for the rotating roller 615 to rotate, thereby ensuring the stability of the liquid storage box 53 during the operation of the drone, and preventing the liquid storage box 53 from shaking in the outer frame 51 and affecting the flight stability of the drone. When the liquid is sprayed, the gravity of the liquid storage box 53 itself is greatly reduced. At this time, the support frame 613 will be reset under the action of the elastic force, so that the rotating roller 615 can continue to rotate, so that the liquid storage box 53 can be taken out more conveniently after the spraying is completed, which greatly saves manpower and material resources. At the same time, by automatically fixing and loosening the liquid storage box 53, the applicability of the drone is also greatly improved.
