Description

Technical Field

[0001] The utility model belongs to the technical field of unmanned aerial vehicle material feeding devices, and in particular relates to an automatic unmanned aerial vehicle material feeding device. Background Art

[0002] With the development of drone technology, the use of drones for short- and medium-distance fixed-point delivery has become a common technology at present. However, in order to meet the requirements of automatic control feeding, the existing drones usually have a limited number of mounted materials. If more materials need to be mounted, the corresponding material fixing mechanism and feeding control device will be added. For example, the patent with application number CN201922446623.2 discloses a feeding device for drones, which includes: a driving mechanism and a clamping assembly, the driving mechanism connects and drives the clamping assembly; the clamping assembly includes a clamping box, a first screw rod, a second screw rod and two clamping arms. When feeding, the first screw rod and the second screw rod are driven to rotate by the driving mechanism, so that the clamping arms are close to clamp the object, and then the drone is transported to the designated position, and the first screw rod and the second screw rod rotate in the opposite direction, so that the two clamping arms are separated and the object is automatically delivered. This feeding device only has a material mounting position formed between the two clamping arms, so it can only deliver materials once, and cannot deliver multiple times in one flight.

[0015] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0016] like Figures 1 to 3 As shown, an automatic feeding device for a drone includes: a shell 1, a turntable 2 and a motor 4.

[0017] Specifically, the middle of the shell 1 has a circular structure and a through hole running through both ends of the shell 1. The bottom of the shell 1 is provided with a notch 11 connected to the through hole. The shell 1 is arranged at the bottom of the drone.

[0018] Specifically, the turntable 2 is coaxially arranged in the through hole of the shell 1, and the turntable 2 is rotatably arranged around the axis. The outer wall of the turntable 2 is provided with a plurality of slots 21 spaced apart along the circumference for accommodating materials. The opening size of the slot 21 is smaller than the opening size of the notch 11. The turntable 2 is provided with a baffle 3 at the opening corresponding to the slot 21, one side of which is hinged to the side of the slot 21. Along the rotation direction of the turntable 2, the slot 21 is used to hinge the side of the baffle 3 and is located in front of the other side. The width of the baffle 3 is greater than the opening size of the slot 21 and smaller than the opening size of the notch 11. A compression member 31 is provided on the surface of the baffle 3 facing the slot 21; when the slot 21 is facing the bottom of the shell 1, the slot 21 is aligned with the notch 11, and the baffle 3 opens downward; when the slot 21 is facing the inner wall of the circular hole of the shell 1, the baffle 3 closes the slot 21, and the compression member 31 presses the material into the slot 21.

[0019] Specifically, the motor 4 is disposed on the housing 1 and is used to drive the turntable 2 to rotate.

[0020] For ease of description, in this embodiment, the rotation direction of the turntable 2 is set to be counterclockwise, and the use of the automatic feeding device mainly includes two states: feeding and feeding.

[0021] Feeding: Turn the turntable 2 to align the slot 21 to be fed with the notch 11. At this time, the baffle 3 will automatically open downward under the action of gravity, and the material will be placed in the slot 21. Figure 2 The turntable 2 is rotated counterclockwise in the direction indicated by the arc arrow. When the turntable 2 rotates, the slot 21 will gradually be misaligned with the notch 11. In this process, the side wall of the notch 11 can be used to press against the outer surface of the baffle 3, so that the baffle 3 swings toward the opening of the slot 21. When the slot 21 is facing the inner wall of the circular hole of the shell 1, the baffle 3 closes the slot 21. At this time, the compression member 31 can be used to press the material into the slot 21 to prevent the material from falling and avoid friction between the material and the inner wall of the through hole. In the above manner, materials are placed in multiple slots 21. When adding materials, the turntable 2 can be rotated manually or the motor 4 can be used to drive the turntable 2 to rotate.

[0022] Feeding, when the UAV flies to the feeding position, the motor 4 is used to drive the turntable 2 to rotate counterclockwise. When the slot 21 is aligned with the notch 11, the baffle 3 also loses the limit of the inner wall of the through hole. The baffle 3 will swing downward quickly under the action of its own gravity and the elastic force of the compression member 31 when it recovers its deformation, and then the material can automatically fall from the slot 21, thereby completing the feeding work. Because the outer wall of the turntable 2 is provided with a plurality of slots 21, multiple feedings can be carried out in one flight, and only one motor 4 is needed to automatically control the feeding timing. The overall structure of the device is simple, and the feeding and adding operations are convenient.

[0023] Preferably, Figure 2As shown, a bracket 12 is provided at one end of the shell 1, and there is a predetermined distance between the bracket 12 and the end surface of the shell 1, so as to make more space for the material, so as to facilitate the placement of longer materials. The motor 4 is arranged on the outside of the bracket 12, and the main shaft of the motor 4 is coaxially connected to the turntable 2 to reduce the intermediate transmission mechanism, thereby simplifying the device structure and reducing the weight.

[0024] Preferably, the extending directions of the slot 21 and the notch 11 are consistent with the axial direction of the turntable 2 to facilitate manufacturing and processing.

[0025] Preferably, Figure 3 As shown, a roller 32 is provided on the other side of the baffle 3 opposite to the hinge. When the turntable 2 rotates in the through hole of the housing 1, the roller 32 rolls in contact with the inner wall of the through hole to reduce friction resistance.

[0026] Preferably, Figure 3 As shown, a compression spring 22 is provided at the bottom of the slot 21. When the material is placed in the slot 21, the compression spring 22 is in a compressed state, which not only improves the compaction effect on the material, but also after the baffle 3 is opened, the elastic force of the compression spring 22 can be used to quickly eject the material, thereby increasing the material discharge speed.

[0027] Further preferably, the compression member 31 is a cylindrical spring or a spring plate.

[0028] The above is only a preferred embodiment of the utility model, and does not mean that it is the only one or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
