Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a landing buffer device for plant protection UAVs. Background Technology

[0002] Agricultural drones, also known as unmanned aerial vehicles, are unmanned aircraft used for the protection of agricultural and forestry plants. These drones consist of three parts: a flight platform, a navigation and flight control system, and a spraying mechanism. They are used for spraying operations via ground remote control or navigation and flight control, and are mainly used for spraying pesticides, fertilizing, irrigating, or other plant protection activities.

[0003] After spraying pesticides, agricultural drones need to land to re-spray pesticides. When landing, the drones are relatively stable on flat ground due to uneven ground and the fact that most existing agricultural drone landing supports are fixed. However, on uneven ground, the drones may tilt upon landing, which could lead to loss of control or tipping over, resulting in damage to the drones. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The technical problem this invention aims to solve is that uneven ground can cause agricultural drones to tilt upon landing, leading to loss of control or tipping over and damage to the drones.

[0006] (II) Technical Solution

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a landing buffer device for a plant protection drone, including a drone body, four sleeves 1 on the bottom surface of the drone body, a plug inserted into the sleeve 1, a buffer spring between the plug and the sleeve 1, a sleeve 2 at one end of the plug, a pointed cone inserted into the ground on the bottom surface of the sleeve 2, and an auxiliary mechanism on the plug to protect the pointed cone and assist landing.

[0008] As an improvement, the auxiliary mechanism includes a ring that is movably fitted onto the sleeve two, a spring between the ring and the insert post, an extension post on the bottom surface of the ring, a protective ring on the extension post, and the bottom surface of the protective ring coinciding with the bottom surface of the pointed cone.

[0009] As an improvement, the sleeve is provided with an extension plate, the insert is provided with an extension plate, and a damper is provided between the extension plate and the extension plate.

[0010] As an improvement, the spring is located between the extension plate two and the ring and is sleeved on the insert post, with one end of the spring abutting against the extension plate two.

[0011] As an improvement, the second sleeve is threadedly connected to the insert post.

[0012] As an improvement, the insertion post is provided with a limiting rod, and the ring is provided with a limiting groove that cooperates with the limiting rod.

[0013] As an improvement, both ends of the insertion post are provided with limiting rings to limit the movement of the circular ring.

[0014] (III) Beneficial Effects

[0015] The advantages of this utility model compared with the prior art are as follows:

[0016] By incorporating a sleeve, a post, a buffer spring, a sleeve, a cone, and an auxiliary mechanism, when the drone finishes spraying pesticides and needs to land, the auxiliary mechanism can cover the cone during spraying to prevent accidental injury to pedestrians. When the drone lands, the cone can be inserted into the soil, and the auxiliary mechanism can help fix it in place. The post, buffer spring, and sleeve can absorb the force generated by landing, and the cone can adapt to uneven ground, thus ensuring a smooth landing for the drone. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] As per the instructions Figures 1 to 4 As shown, a landing buffer device for a plant protection drone includes a drone body 1. The bottom surface of the drone body 1 is provided with four sleeves 2. Inserted posts 3 are movably inserted into the sleeves 2. A buffer spring 4 is provided between the inserted posts 3 and the sleeves 2. One end of the inserted post 3 is provided with a sleeve 5. The bottom surface of the sleeve 5 is provided with a pointed cone 6 that is inserted into the ground. An auxiliary mechanism 7 is provided on the inserted post 3 to protect the pointed cone 6 and assist landing.

[0026] The sleeve 2 is provided with an extension plate 12, the insert 3 is provided with an extension plate 2 13, and a damper 14 is provided between the extension plate 12 and the extension plate 2 13.

[0027] Agricultural drones are existing technology and will not be elaborated here. When the drone body 1 finishes spraying and needs to land, the ground is soil, and its surface may be uneven. Compared with a normal landing frame, the drone may tip over and be damaged due to the uneven ground. When the drone body 1 of this application lands, the auxiliary mechanism 7 no longer protects the pointed cone 6, allowing it to be exposed. At the same time, the auxiliary mechanism 7 assists in supporting the ground. Generally, agricultural drones are large and have a certain weight, so the pointed cone 6 will insert into the ground during the descent, thus adapting to the uneven bottom surface. At the same time, the force of the fall will compress the buffer spring 4, thereby buffering the impact force generated by the fall. In order to prevent the buffer spring 4 from swaying back and forth, extension plate 12 and extension plate 2 13 are set on sleeve 1 2 and insert 3, and then a damper 14 is set, thereby reducing the swaying frequency and quickly bringing it to a stop.

[0028] As per the instructions Figures 2 to 6As shown, the auxiliary mechanism 7 includes a ring 8 movably fitted onto the sleeve 5. A spring 9 is provided between the ring 8 and the insertion post 3. An extension post 10 is provided on the bottom surface of the ring 8. A protective ring 11 is provided on the extension post 10. The bottom surface of the protective ring 11 coincides with the bottom surface of the cone 6. When the UAV body 1 takes off, in order to prevent the cone 6 from hitting people or plants and causing damage, the auxiliary mechanism 7 is set up. When not in contact with the ground, the protective ring 11 and the bottom surface of the cone 6 are on the same plane, so that the cone 6 can prevent the cone 6 from causing damage to people or plants. When the UAV body 1 lands, the protective ring 11 contacts the ground. Then, under the action of the gravity of the UAV body 1, the protective ring 11 is forced to move upward. At the same time, the cone 6 is inserted into the soil, the spring 9 is compressed, and the protective ring 11 contacts the soil surface, which can increase the support area and thus improve the landing stability.

[0029] The spring 9 is located between the extension plate 2 13 and the ring 8 and is sleeved on the insertion post 3. One end of the spring 9 abuts against the extension plate 2 13. The sleeve 2 5 is threadedly connected to the insertion post 3. The insertion post 3 is provided with a limiting rod 15. The ring 8 is provided with a limiting groove that cooperates with the limiting rod 15. Both ends of the insertion post 3 are provided with limiting rings 16 to limit the ring 8. When using the UAV body 1, the ground is sometimes relatively flat. At this time, the sleeve 2 5 can be removed and replaced with a normal landing gear, which is highly adaptable. By setting the limiting rings 16, the ring 8 can be prevented from falling off the insertion post 3. In order to make the ring 8 move more smoothly on the insertion post 3, a guide wheel can be set in the limiting groove on the ring 8, and then a guide groove can be set on the limiting rod 15. The guide wheel and guide groove are existing technologies and will not be described in detail here.

[0030] In practical use, the drone body 1 is first placed on the ground, with the pointed cone 6 inserted into the soil. At this time, the auxiliary mechanism 7 no longer protects the pointed cone 6. Then, the liquid medicine is put into the medicine tank of the drone body 1, and the drone body 1 is started. The drone body 1 rises, and the pointed cone 6 leaves the ground. Then, the auxiliary mechanism 7 protects the pointed cone 6. After the liquid medicine is sprayed, the drone body 1 lands. At this time, the auxiliary mechanism 7 no longer protects the pointed cone 6, and the pointed cone 6 inserts into the ground. The impact generated during the fall will cause the sleeve 2 to move down, thereby compressing the buffer spring 4 and then rebounding. The damper 14 can reduce the number of rebounds, so that the drone body 1 can quickly stabilize. The protective ring 11 can increase the support area and can also protect the pointed cone 6 during the flight of the drone body 1 to prevent harm to people or plants. When the ground is flat and not soil, the ring 8 can be removed and a normal landing frame can be replaced.
