Description

Technical Field

[0001] This utility model relates to the field of drone pollination, and in particular to a retractable and foldable parachute-type drone for pollinating tall crops. Background Technology

[0002] The parachute-type tall crop pollination drone is a new type of aircraft that integrates the lift characteristics of flexible parachute with a power propulsion device. The drone is equipped with a driver and propeller at the rear or bottom, which can provide continuous thrust to achieve active climbing and improved endurance. It can use downwash airflow to disperse pollen and is also equipped with intelligent devices to accurately plan the path and efficiently complete the pollination task.

[0003] The power unit of the paraglider-type tall crop pollination drone provides continuous thrust, enabling it to maintain altitude and actively climb. During flight, the flight control device adjusts the engine thrust in real time based on wind field perception and prediction to maintain stable heading and altitude. At the same time, the drone releases and disperses pollen to complete the pollination task.

[0004] Currently, the wings of some parachute-type tall crop pollination drones are difficult to fold, taking up a lot of space when stored, which is not conducive to transportation and storage, increasing storage costs and transportation difficulties. Secondly, the deployment and retrieval efficiency is low, and the preparation and sorting work before and after each use is cumbersome, consuming time and manpower. Therefore, a retractable and foldable parachute-type tall crop pollination drone is proposed to solve the above problems. Utility Model Content

[0013] As a further description of the above technical solution:

[0014] Two landing gears are fixedly connected to the bottom of the machine body, and the external of the second hydraulic cylinder is rotatably connected to the inside of the machine body;

[0015] As a further description of the above technical solution:

[0016] The hydraulic cylinder is externally fixedly connected to the outside of the support rod, and one end of the rotating plate is rotatably connected to one end of the fixed plate.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the expansion and folding of the parasol wings are achieved by driving the moving plate with a hydraulic cylinder, which in turn drives the rotating rods to rotate. When expanding, the hydraulic cylinder pulls the moving plate, and the rotating rod moves the rotating plate outward, so that the parasol wings expand from the middle. When folding, the hydraulic cylinder pushes the moving plate, and the rotating rod causes the sliding block to move in the groove of the rotating plate, so that the rotating plate folds inward, thus completing the folding of the parasol wings. The entire process realizes the expansion and folding function of the parasol wings through a linkage structure.

[0025] 2. In this utility model, the rotating cover is opened, and powder is poured into the machine body through the feed port. The motor is started to drive the propeller to rotate. After the drone arrives at the designated location, the hydraulic cylinder two is started, which drives the rotating ring and multiple swing rods to rotate, so that the rotating block rotates around the limit post to open. Since the pollen characteristics and pollination methods of different tall crops vary greatly, the size of the outlet needs to be adjusted to match the requirements. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3 The present invention provides an embodiment of a retractable and foldable parachute-type tall crop pollination drone, comprising a body 1, a support rod 3 fixedly connected to the top of the body 1 for support, a parachute 4 fixedly connected to the top of the support rod 3 for providing lift and flight stability to the drone, a folding mechanism 5 installed inside the parachute 4 for controlling the unfolding and retraction of the parachute 4 for easy storage, and an adjustment mechanism 6 installed inside the body 1 for adjusting the flight attitude and altitude of the drone.

[0034] The folding mechanism 5 includes a hydraulic cylinder 51, with a movable plate 52 fixedly connected to the drive end of the hydraulic cylinder 51. The extension and retraction of the hydraulic cylinder 51 drives the movable plate 52 to move. Two fixed plates 53 are fixedly connected to the outer wall of the parachute 4, providing a pivot point for rotation. Rotating rods 54 and 55 are rotatably connected to both ends of the movable plate 52. The movement of the movable plate 52 causes rotating rods 54 and 55 to swing synchronously. A rotating plate 57 is rotatably connected to the other end of rotating rod 54. The swinging of rotating rod 54 causes rotating plate 57 to rotate, thus realizing the unfolding or folding of the parachute 4. The other end of the rotating rod 55 is rotatably connected to a sliding block 56. The rotating rod 55 swings and drives the sliding block 56 to slide, which helps the rotating plate 57 to rotate stably. The hydraulic cylinder 51 is externally fixedly connected to the outside of the support rod 3, so that the hydraulic cylinder 51 is installed firmly. One end of the rotating plate 57 is rotatably connected to one end of the fixed plate 53. The rotating plate 57 rotates with the fixed plate 53 as the fulcrum. The two ends of the moving plate 52 are slidably connected to the inside of the two fixed plates 53, ensuring that the moving plate 52 moves smoothly along the fixed plate 53. The outside of the sliding block 56 is slidably connected to the inside of the rotating plate 57. The sliding block 56 slides along the groove of the rotating plate 57.

[0035] The body 1 is equipped with a drive assembly 7, which includes a motor 71. The outer wall of the motor 71 is fixedly connected to the inside of the body 1 to ensure that the motor 71 is firmly installed. The drive end of the motor 71 is fixedly connected to a propeller 72. The rotation of the propeller 72 generates thrust to drive the drone to fly.

[0036] Reference Figure 3 and Figure 4The adjusting mechanism 6 includes a second hydraulic cylinder 61, which provides power to the adjusting mechanism 6. A rotating ring 62 is rotatably connected to the drive end of the second hydraulic cylinder 61. The extension and retraction of the second hydraulic cylinder 61 drives the rotating ring 62 to rotate. Multiple swing rods 64 are rotatably connected to the top of the rotating ring 62. The rotation of the rotating ring 62 causes the swing rods 64 to swing. A rotating block 65 is rotatably connected to the other end of each swing rod 64. The swing rods 64 push the rotating block 65 to rotate. A limit post 66 is rotatably connected inside the rotating block 65, providing a fulcrum for the rotation of the rotating block 65. Multiple fixed posts 63 are fixedly connected inside the body 1, restricting the movement trajectory of the rotating ring 62. The outer walls of the fixed posts 63 are slidably connected to... In the groove of the rotating ring 62, the rotating ring 62 rotates along the trajectory of the fixed column 63. The bottom of the rotating ring 62 is rotatably connected to the inside of the body 1 to ensure the stability of the rotating ring 62 during rotation. The bottom of the limiting column 66 is fixedly connected to the inside of the body 1 to ensure that the limiting column 66 is installed securely. The outside of the hydraulic cylinder 61 is rotatably connected to the inside of the body 1. The hydraulic cylinder 61 drives the rotating ring 62 to rotate. Two landing gears 2 are fixedly connected to the bottom of the body 1. The landing gears 2 are used for support during the take-off and landing of the UAV. The top of the body 1 is fixedly connected to the feed inlet 8. The feed inlet 8 is used to add the materials required for pollination. The top of the feed inlet 8 is equipped with a cover plate 9. The cover plate 9 is used to close the feed inlet 8 to prevent material leakage or impurities from entering.

[0037] Working principle: Start hydraulic cylinder 51, which pulls the moving plate 52. The moving plate 52 moves and drives the rotating rods 54 and 55 at both ends to rotate. The rotation of the rotating rod 54 drives the rotating plate 57 to move outward, thereby unfolding the parachute 4 from the middle. After use, start hydraulic cylinder 51 again, which pushes the moving plate 52. The moving plate 52 drives the rotating rods 54 and 55 to rotate. The rotating rod 55 pushes the sliding block 56 to move in the groove inside the rotating plate 57, thereby folding the rotating plate 57 inward, so that the parachute 4 can be folded.

[0038] Rotate cover plate 9 to open it, and pour the powder into the machine body 1 through feed port 8. Start motor 71, which drives propeller 72 to rotate. When the drone flies to the designated location, start hydraulic cylinder 61. Hydraulic cylinder 61 drives rotating ring 62 to rotate. Rotating ring 62 drives multiple swing rods 64 to rotate simultaneously. The rotation of swing rods 64 drives rotating block 65 to rotate. Because one end of rotating block 65 is restricted by limit post 66, rotating block 65 rotates around limit post 66, thereby opening rotating block 65. Because the pollen characteristics and pollination methods of different tall crops vary significantly, it is necessary to adjust the outlet size to match the requirements.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
