Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0046] Embodiment 1

[0047] Please refer to the accompanying drawings, the present invention provides a technical solution:

[0048] A remote delivery device for a drone includes a mounting platform 100, wherein support rods 102 inclined outwardly are fixed at the four corners of the bottom of the mounting platform 100, and a horizontal support seat 103 is fixed at the bottom end of the support rod 102;

[0049] A fixing box 101 is fixed to the bottom of the mounting platform 100, and a driving assembly is arranged in the fixing box 101. A vertical fixing shaft 400 is fixed to the top inner section of the support seat 103, and the top end of the fixing shaft 400 passes through the fixing box 101 and is fixedly connected to the bottom surface of the mounting platform 100;

[0051] A material discharge port 202 is provided at the bottom of the loading box 200, the inner cavity bottom surface of the loading box 200 is inclined toward the material discharge port 202, and a sealing assembly is provided in the material discharge port 202, a return assembly is provided at the lower part of the fixed shaft 400, and the sealing assembly is connected to the return assembly accordingly;

[0052] A movable support structure is commonly provided at the bottom of the multiple loading boxes 200. The top center of the movable support structure is correspondingly connected to the bottom center of the fixed box 101, and the four corners of the bottom of the movable support structure are correspondingly connected to four return assemblies respectively.

[0053] When loading materials into the loading box 200, the mobile support structure moves downward and disengages from the bottom of the loading box 200, thereby reducing friction during subsequent rotation of the loading box 200. Then, the driving assembly drives the four rotating assemblies to drive the corresponding loading box 200 to rotate to one side, so that the top opening of the loading box 200 can be rotated out from under the mounting platform 100, and material filling is carried out, thereby completing the loading operation of the loading box 200.

[0054] After loading is completed, the driving assembly drives the rotating assembly and the corresponding loading box 200 to rotate back to their original positions, and the mobile support structure moves upward to contact the bottoms of the four loading boxes 200, supporting and limiting the bottoms of the loading boxes 200, thereby improving the position stability of the loading boxes 200 and the safety of drone transportation.

[0055] When material needs to be dropped in, the driving assembly drives the four rotating assemblies to rotate the loading box 200 to the other side, and when the loading box 200 rotates to the feeding position, the sealing assembly automatically opens the discharge port 202, so that the material can be quickly discharged from the discharge port 202, completing the material dropping operation.

[0056] After the delivery is completed, the sealing component is returned to its position through the return component so that the discharge port 202 can be closed again, and then the loading box 200 is returned to its position through the action of the driving component and the rotating component. After returning to its position, the movable support structure moves up and back to its position again to provide limited support for the loading box 200.

[0057] The present invention sets the top of the loading box 200 in an open shape, and when loading, the loading box 200 is rotated out from under the mounting platform 100, so as to facilitate the rapid filling of materials and make the loading operation faster and more convenient; and controls the position of the loading box 200 by a driving component and a rotating component, so that when it is rotated out to one side, loading is carried out, and when it is rotated out to the other side, the sealing component automatically opens the discharge port 202 to realize the rapid delivery of materials, and the sealing component can be returned to its position after the feeding is completed through the return component to avoid affecting the movement of the loading box 200.

[0058] The present invention provides a movable support structure at the bottom of the loading box 200 so as to provide support or cancel support according to the movement and state of the loading box 200, thereby improving the position stability of the loading box 200 and reducing the impact on the rotation of the loading box 200.

[0059] Among them, the sealing assembly includes a sealing plate 203 located in the discharge port 202, a horizontal rotating shaft 204 is fixed in the middle of the sealing plate 203, and the rotating shaft 204 is rotatably connected to the side wall of the discharge port 202.

[0060] When the bottom end of the sealing rack 208 is located at the top of the fixed platform 401, the position of the sealing rack 208 is limited by the fixed platform 401, and then the position of the sealing plate 203 is limited by the sealing gear 207 and the rotating shaft 204, so that the discharge port 202 remains closed; when the loading box 200 is rotated to one side for loading, the sealing rack 208 rotates to a position away from the moving groove 402 and is always located at the top of the fixed platform 401 to keep the discharge port 202 closed; when the loading box 200 is rotated to the other side for unloading, the sealing rack 208 moves along the top surface of the fixed platform 401 to the moving groove 402, and moves downward along the moving groove 402 under the action of the spring, so that the sealing gear 207 and the rotating shaft 204 drive the sealing plate 203 to rotate, open the discharge port 202, so that the material in the loading box 200 can be discharged along the discharge port 202, thereby realizing material delivery.

One end of the spring seat 302 is connected to the end of the spring groove 104 through a spring, and the other end extends out of the spring groove 104 and is correspondingly connected to the bottom of the mobile support structure. A pushing block 303 is fixed on the top of the spring seat 302, and the position of the pushing block 303 corresponds to the position of the top wheel 404, and an inclined surface is provided on the side of the pushing block 303 close to the top wheel 404.

[0063] When the material is put into the container, the supporting structure moves downward, pushing the spring seat 302 to move, so that the pushing block 303 on it moves toward the top wheel 404, and during the movement, the top wheel 404 is lifted up, so that the moving cylinder 403 drives the top block 405 to move upward, and the top block 405 moves along the moving groove 402, pushing out the top end of the sealing rack 208 and locating it at the top height of the fixed platform 401, so that the structure of the sealing plate 203 returns to its original position, so that the loading box 200 can be smoothly rotated and returned to its original position, and the sealing rack 208 can move back to its original position along the top surface of the fixed platform 401.

[0065] When the loading box 200 needs to be rotated, the support plate 300 is moved down by the hydraulic telescopic rod 304 to contact the bottom of the loading box 200, and the connecting rod 301 drives the spring seat 302 and other structures to move a small distance. When the sealing assembly needs to be returned, the support plate 300 is further moved down by the hydraulic telescopic rod 304, and then the spring seat 302 is further pushed to move by the connecting rod 301, so that the top wheel 404 and the moving cylinder 403 are lifted up by the pushing block 303 on the spring seat 302, thereby realizing the return operation of the sealing assembly.

[0066] Among them, the limiting blocks 305 are symmetrically fixed on both sides of the spring seat 302, and horizontal limiting grooves 105 are correspondingly provided on the two side walls of the spring groove 104, and the limiting blocks 305 are slidably connected in the limiting grooves 105. The limiting grooves 105 and the limiting blocks 305 play a limiting and guiding role for the spring seat 302, so that it can only move horizontally along the length direction of the spring groove 104.

[0069] The driving assembly includes a rotating toothed disc 500 located at the center of the fixed box 101, and four transmission gears 504 are evenly meshed on the rotating toothed disc 500.

During the rotation, the rotating toothed disk 500 is rotated to one side by a certain angle through the connecting groove 501, so that the transmission gear ring 209 and the rotating cylinder 201 drive one side of the loading box 200 to rotate out for loading; then the motor continues to rotate, and the driving disk 502 drives the rotating toothed disk 500 to rotate a certain angle through the connecting shaft 503 and the connecting groove 501, so that the loading box 200 returns to its position, and then the motor continues to rotate, through the action of the driving disk 502 and the connecting shaft 503, the rotating toothed disk 500 is rotated to the other side by a certain angle, so that the loading box 200 is rotated to the other side and the material is delivered. After the delivery is completed, the motor rotates again to return the rotating toothed disk 500 and the loading box 200 returns to its position.
