Description

Technical Field

[0001] This utility model belongs to the field of agricultural transport drone technology, and in particular relates to an agricultural transport drone with an anti-tipping structure. Background Technology

[0002] With the continuous improvement of agricultural modernization, drones, due to their high efficiency and flexibility, have been increasingly widely used in agricultural transportation, such as pesticide spraying, fertilizer spreading, seed transportation, and agricultural product transshipment.

[0003] Chinese patent CN212354378U discloses an agricultural drone that is easy to transport, including a frame, a wireless receiver, a rotor device, support feet, a power storage device, a switch, a portable feed box, a camera, a wireless transmitter, a GPS positioning block, and a folding device. This utility model is a multifunctional drone photoelectric monitor, which is stably connected to the frame through a connecting sleeve one, a fixing clip, and a connecting sleeve two via a folding device.

[0004] As shown above, the device is equipped with a folding mechanism. It is securely connected to the frame via connecting sleeve one, fixing clip and connecting sleeve two. By pressing the quick release switch, the trip pin and hook are separated, and then connecting sleeve one rotates on connecting sleeve two via the pivot, causing the four ends of the frame to fold upwards. This solves the problem of taking up too much space when not in use. However, its support legs are too small and insufficient to support the drone to land smoothly. During landing, it may tip over, which may lead to damage to the drone. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides an agricultural transport drone with an anti-tipping structure, which solves the problem of the drone potentially tipping over during landing.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an agricultural transport drone with an anti-tipping structure, comprising a fuselage body, wherein a plurality of rotors are fixedly connected to the inner wall of the fuselage body, an anti-tipping mechanism is provided at the bottom of the fuselage body to prevent tipping during take-off and landing, and a clamping mechanism is provided at the bottom of the fuselage body to clamp and fix the medicine box. The anti-tipping mechanism includes a fixed plate fixedly connected to the bottom of the main body. Two sets of fixed frames are fixedly connected to the bottom of the fixed plate, two in each set. The four fixed frames contain the same internal parts. A fixed block is slidably connected to the inner wall of the fixed frame. A first support plate is fixedly connected to the bottom of the fixed block. A second support plate is rotatably connected to the outer wall of the first support plate. A sliding block is slidably connected to the inner wall of the second support plate. A fixed shaft is fixedly connected to the inner wall of the sliding block. A rotating block is rotatably connected to the outer wall of the fixed shaft. An electric push rod is fixedly connected to the outer wall of the rotating block.

[0007] Preferably, a spring is fixedly connected to the top of the fixing block, the end of the spring away from the fixing block is fixedly connected to the outer wall of the fixing plate, and a damper is fixedly connected to the top of the fixing block.

[0008] Preferably, the damper is fixedly connected to the outer wall of the fixed plate on the side away from the fixed block, and the damper is located inside the spring.

[0009] Preferably, the clamping mechanism includes a storage housing fixedly connected to the bottom of the fixed plate, the outer wall of the storage housing being fixedly connected to the side of the electric push rod away from the rotating block, and a door panel being hinged to the inner wall of the storage housing.

[0010] Preferably, a bidirectional lead screw is rotatably connected to the inner wall of the storage housing. One end of the bidirectional lead screw passes through the outer wall of the storage housing and extends to the outside of the storage housing. A worm gear is fixedly connected to the outer wall of the bidirectional lead screw. A worm is meshed with the outer wall of the worm gear. The outer wall of the worm is rotatably connected to the inner wall of the storage housing.

[0011] Preferably, the outer wall of the bidirectional lead screw is threaded with two clamping plates for clamping the medicine box, and the inner wall of the storage shell is fixedly connected with two guide blocks. The inner walls of the two guide blocks are slidably connected to the outer wall of the clamping plates for limiting the position of the clamping plates.

[0012] This utility model has the following beneficial effects: 1. This agricultural transport drone with an anti-tipping structure, when it needs to land, activates an electric push rod via an external controller. This pushes a rotating block to move, causing a sliding block to slide on the second support plate. Ultimately, this drives the second support plate to unfold to a state parallel to the first support plate, thereby increasing the ground contact area and forming a stable support platform to prevent tipping. At the moment of landing, the impact force generated by the drone is concentrated on the first and second support plates. At this time, the buffer system composed of dampers and springs can effectively absorb and dissipate kinetic energy, providing buffer protection for the drone and preventing it from being damaged or tipping over due to impact.

[0013] 2. This agricultural transport drone with an anti-tipping structure, when it needs to secure the medicine box, first places the medicine box into the storage shell, then manually rotates the worm gear, driving the meshing worm wheel to rotate, which in turn drives the bidirectional lead screw to rotate. The rotation of the bidirectional lead screw drives the two clamping plates on it to move towards each other and move closer together, thus firmly clamping the medicine box from both sides. During this process, the guide block provides guidance and limit for the movement of the clamping plates, ensuring the smoothness of the clamping movement. It realizes the rapid and stable clamping of medicine boxes of different sizes, effectively preventing the drone's attitude from becoming unstable due to the shaking of the medicine box during transportation, improving operational safety and equipment versatility.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0018] 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.

[0019] This utility model provides two technical solutions: Figures 1-3 The first embodiment of an agricultural transport drone with an anti-tipping structure is shown: an agricultural transport drone with an anti-tipping structure includes a fuselage body 1, a plurality of rotors 101 are fixedly connected to the inner wall of the fuselage body 1, an anti-tipping mechanism 2 is provided at the bottom of the fuselage body 1 to prevent tipping during take-off and landing, and a clamping mechanism 3 is provided at the bottom of the fuselage body 1 to clamp and fix the medicine box. The anti-tipping mechanism 2 includes a fixed plate 201 fixedly connected to the bottom of the main body 1. Two sets of fixed frames 202 are fixedly connected to the bottom of the fixed plate 201, with two frames in each set. The four fixed frames 202 contain the same internal parts. A fixed block 203 is slidably connected to the inner wall of the fixed frame 202. A first support plate 205 is fixedly connected to the bottom of the fixed block 203. A second support plate 206 is rotatably connected to the outer wall of the first support plate 205. A sliding block 207 is slidably connected to the inner wall of the second support plate 206. A fixed shaft 208 is fixedly connected to the inner wall of the sliding block 207. A rotating block 209 is rotatably connected to the outer wall of the fixed shaft 208. An electric push rod 210 is fixedly connected to the outer wall of the rotating block 209. The electric push rod 210 is activated by an external controller, which pushes the rotating block 209 to move, causing the sliding block 207 to slide on the second support plate 206, and finally driving the second support plate 206 to unfold to a state parallel to the first support plate 205, thereby increasing the grounding area.

[0020] A spring 204 is fixedly connected to the top of the fixed block 203. The end of the spring 204 away from the fixed block 203 is fixedly connected to the outer wall of the fixed plate 201. A damper 211 is fixedly connected to the top of the fixed block 203. The impact force generated by the drone is concentrated on the first support plate 205 and the second support plate 206. At this time, the buffer system composed of the damper 211 and the spring 204 can effectively absorb and dissipate the kinetic energy, providing buffer protection for the drone.

[0021] The side of the damper 211 away from the fixed block 203 is fixedly connected to the outer wall of the fixed plate 201, and the damper 211 is located inside the spring 204.

[0022] When the drone needs to land, the electric push rod 210 is activated by the external controller, which in turn pushes the rotating block 209. As the rotating block 209 moves, the position of the fixed shaft 208 also moves, and the rotating block 209 rotates on the fixed shaft 208. This causes the sliding block 207 to slide within the second support plate 206. As the sliding block 207 slides on the second support plate 206, the second support plate 206 gradually becomes parallel to the first support plate 205, increasing the area to form a stable support. During takeoff, the upward operation is repeated in the opposite direction, and the second support plate 206 is retracted to prevent excessive wind resistance during flight. When the second support plate 206 is parallel to the first support plate 205, the drone can land. At the moment of landing, the pressure of the drone itself is concentrated on the first support plate 205 and the second support plate 206. At this time, the damper 211 and the spring 204 absorb the generated kinetic energy, cushioning the drone as a whole and preventing damage or tipping of the drone.

[0023] Figure 4 The second embodiment is shown. The main difference between this embodiment and the first embodiment of the agricultural transport drone with an anti-tipping structure is that the clamping mechanism 3 includes a storage housing 301 fixedly connected to the bottom of the fixed plate 201. The outer wall of the storage housing 301 is fixedly connected to the side of the electric push rod 210 away from the rotating block 209. A door panel 302 is hinged to the inner wall of the storage housing 301. A bidirectional lead screw 303 is rotatably connected to the inner wall of the storage housing 301. One end of the bidirectional lead screw 303 passes through the outer wall of the storage housing 301 and extends to the outside of the storage housing 301. A worm gear 304 is fixedly connected to the outer wall of the bidirectional lead screw 303. A worm 305 is meshed with the outer wall of the worm gear 304. The outer wall of the worm 305 is rotatably connected to the inner wall of the storage housing 301.

[0024] The outer wall of the bidirectional lead screw 303 is threaded with two clamping plates 306 for clamping the medicine box. The inner wall of the storage shell 301 is fixedly connected with two guide blocks 307. The inner walls of the two guide blocks 307 are slidably connected to the outer wall of the clamping plates 306 for limiting the clamping plates 306. Manually rotate the worm gear 305 to drive the meshing worm wheel 304 to rotate, which in turn drives the bidirectional lead screw 303 to rotate. The rotation of the bidirectional lead screw 303 drives the two clamping plates 306 on it to move towards each other and move closer to each other in sync, thereby firmly clamping the medicine box from both sides.

[0025] When the medicine box needs to be placed, first open the door panel 302 and put the medicine box into the storage housing 301. Then manually turn the worm gear 305 to make the worm wheel 304 rotate. When the worm wheel 304 rotates, the double-acting screw 303 will rotate, thereby making the two clamping plates 306 move closer to each other. At the same time, the presence of the guide block 307 can limit the movement between the two clamping plates 306, so that the two clamping plates 306 move according to the guidance of the guide block 307.
