After the delivery is completed, the torsion spring will release and rebound. It is worth mentioning that at the moment of material delivery, the counterweight block of equivalent weight has arrived at the corresponding placement area to make up for the shortfall in weight, so the drone will not feel weightless, thereby improving flight safety. The subsequent drone can directly fly to the next delivery point and deliver according to the above steps.

[0017] When the drone is needed to perform a delivery operation, the operator can use the threaded grooves and bolt rods arranged at the four corners of the mounting top plate to stably mount the operator and the delivery box on the bottom of the drone, which is portable and practical.

The mounting mechanism 3 includes threaded grooves 31, and the threaded grooves 31 are distributed at the four corners of the mounting top plate 1. Bolt rods 32 are screwed in the middle of the four threaded grooves 31. When the drone is needed to perform a delivery operation, the operator can use the threaded grooves 31 and bolt rods 32 set at the four corners of the mounting top plate 1 to stably install itself and the delivery box 2 at the bottom of the drone. It is portable and practical.

[0026] The multi-point delivery mechanism 4 includes a placement area 41, and the placement area 41 is arranged around the inside of the delivery box 2. The placement area 41 is evenly distributed along the middle periphery of the delivery box 2. An internal frame 42 is fixedly arranged at the top of the inside of the delivery box 2. A safe delivery component 43 is installed inside the four placement areas 41. The safe delivery component 43 includes a transmission screw 431, and two transmission screws 431 distributed up and down are distributed on the outside of the inner frame 42. A synchronous wheel 432 is fixedly arranged around one end of each group of two transmission screws 431, and a synchronous belt 433 is sleeved around the two synchronous wheels 432. A motor 434 is installed at the output end of one of the transmission screws 431, and screw sleeves 435 are screwed around different sides of the two transmission screws 431. A counterweight 436 is mounted on the top of one of the screw sleeves 435, and a stop plate 437 is fixedly arranged at the bottom of the other screw sleeve 435. Sliding guide sleeves 438 are fixed on both sides of each of the two screw sleeves 435, and a guide rod 439 is sleeved on the middle part of one side of the sliding guide sleeve 438. The guide rods 439 are symmetrically distributed along the transverse center axis of the transmission screw 431, and the three are interconnected by the screw sleeves 435. Pulleys 44 are distributed at the inner bottom ends of the four placement areas 41, and a safety delivery component 2 45 is installed on the inner side of the bottom ends of the four placement areas 41. The safety delivery component 2 45 includes a fixing rod 451, and the fixing rod 451 is respectively fixed to the inner side of the bottom ends of the four placement areas 41, and the two ends of the four fixing rods 451 are sleeved with torsion springs 452, and One end of the torsion spring 452 is connected to a baffle 453. When the operator controls the drone and the delivery box 2 to fly to the first area to be delivered, the operator can remotely control one of the motors 434 inside the inner frame 42 to start.

In this state, the support plate 437 will push the material to be delivered to move along the pulley 44 at the bottom of the placement area 41 until the material presses the baffle plate 453 and the torque of the torsion spring 452 causes the plate to rotate at a certain angle, so that the material can finally slide along the inclination of the baffle plate 453 for delivery. After the delivery, the torsion spring 452 will release and rebound. It is worth mentioning that at the moment of material delivery, the counterweight block 436 with a weight equivalent to it has arrived at the corresponding placement area 41 to make up for the missing weight, so it will not cause the drone to feel weightless.To improve flight safety, the subsequent drone can directly fly to the next delivery point and follow the above steps to deliver.

Secondly, when the operator controls the drone and the delivery box 2 to fly to the first area to be delivered, the operator can remotely control one of the motors 434 inside the internal mounting frame 42 to start. At this time, the transmission screw 431 connected to the motor 434 will rotate, and the screw sleeve 435 acting on the screw will carry the counterweight 436 to cooperate with the sliding guide sleeve 438 and the guide rod 439 to move to the inside of the corresponding placement area 41. Since a synchronous wheel 432 is provided at one end of the screw, and a synchronous belt 433 is provided around the periphery of the synchronous wheel 432, and another synchronous wheel 432 is attached to the inner side of the other end of the synchronous belt 433, at this time, another transmission screw 431 inside the synchronous wheel 432 will Rotation, since the two screw threads are opened in opposite directions, the screw sleeve 435 acting on the screw will carry the support plate 437 to cooperate with the corresponding sliding guide sleeve 438 and guide rod 439 to perform displacement operation in the opposite direction of the counterweight block 436. In this state, the support plate 437 will push the material to be delivered to move along the pulley 44 at the bottom of the placement area 41 until the material presses the baffle plate 453 and the torque of the torsion spring 452 causes the plate to rotate at a certain angle, so that the material can finally slide along the inclination of the baffle plate 453 for delivery. After the delivery, the torsion spring 452 will release and rebound. It is worth mentioning that at the moment of material delivery, the counterweight block 436 of equivalent weight has arrived at the corresponding placement area 41 to make up for the shortfall in weight, so it will not cause the drone to feel weightless, thereby improving flight safety. The subsequent drone can directly fly to the next delivery point and deliver according to the above steps.
