[0023] See also Figure 1-4 The utility model provides a sample pushing mechanism of a sample delivery drone, including a drone body 1 and a storage box 2. The storage box 2 is arranged at the bottom of the drone body 1, and a push plate 3 is inserted in the storage box 2. Both ends of the inner cavity surface of the storage box 2 are provided with openings 6 which are symmetrically distributed. A first threaded rod 7 is rotatably connected to the inside of one of the openings 6. A first motor 9 is fixed to the surface of one side of the storage box 2. One side of the first threaded rod 7 passes through the storage box 2 and is fixed to the output end of the first motor 9. The outer circumferential surface of the first threaded rod 7 is located at a position of the inner part of the adjacent position opening 6 and is threadedly connected to a first threaded sleeve 8. One end of the first threaded sleeve 8 passes through the adjacent position opening 6 and is fixed to the surface of the push plate 3. One side of the push plate 3 is provided with a T-shaped cross-section. The baffle 5 and the surface of one side of the storage box 2 are provided with two slots 12, and the two sides of the baffle 5 are fitted with the inner surfaces of the slots 12. Two symmetrically distributed connecting strips 4 are fixed at the middle position of the push plate 3 and the baffle 5. After the sample is transported to the corresponding position by the drone body 1, the first motor 9 is started so that the push plate 3 and the baffle 5 can move in the horizontal direction, so that the push plate 3 can push the items placed in the storage box 2 out of the storage box 2, thereby achieving automatic unloading, thereby improving the efficiency of transporting samples by the sample delivery drone. When the baffle 5 moves horizontally to fit with the inner surface of the slot 12, the baffle 5 is prevented from shaking due to the interference between the hole wall on the surface of the baffle 5 and the positioning shaft 13.

[0024] Further Figure 1 , Figure 3 and Figure 4 As shown, it is worth specifically explaining that two U-shaped connecting seats 14 are fixed to the outer peripheral surface of the bottom of the drone body 1 located at the top of the storage box 2, and a rod groove 16 is opened at the middle position of the bottom surface of the connecting seat 14. The inside of the rod groove 16 is rotatably connected with a second threaded rod 17, and a second motor 15 is fixed to the surface of one end of one of the connecting seats 14. One end of the second threaded rod 17 passes through the connecting seat 14 at the adjacent position and is fixed to the output end of the second motor 15. The outer peripheral surface of the second threaded rod 17 is located at the adjacent position. The two ends of the inner part of the rod groove 16 are threadedly connected with symmetrically distributed second threaded sleeves 18, and the bottom of the second threaded sleeve 18 is hinged with a connecting rod 19. The bottom of the connecting rod 19 is hinged to the surface of the top of the storage box 2, and the second threaded rod 17 can be rotated by starting the second motor 15. Since the external thread structures at both ends of the outer circumference of the second threaded rod 17 are arranged in opposite directions and the inner cavity surface of the rod groove 16 can play a role of resisting and limiting the second threaded sleeve 18, when the second threaded rod 17 rotates, the distance between the second threaded sleeves 18 at two adjacent positions can be changed under the cooperation between the internal thread structure on the inner wall of the second threaded sleeve 18 and the corresponding external thread structure on the outer circumference of the second threaded rod 17, so that the connecting rod 19 can change its angle, so that the storage box 2 can change its height.

[0025] Further Figure 4 As shown, it is worth explaining in detail that the other ends of the two second threaded rods 17 pass through the connecting seat 14 at the adjacent position and extend to one end position of the connecting seat 14, and the outer peripheral surface fixed sleeve of the second threaded rod 17 extending out of the outer part of the connecting seat 14 is provided with a pulley 22, and a connecting belt 23 is provided at the middle position of the two pulleys 22. When one of the second threaded rods 17 rotates, it can drive one of the pulleys 22 to rotate, so that the other pulley 22 can drive the other second threaded rod 17 to rotate under the connecting action of the connecting belt 23.

[0026] Further Figure 2 As shown, it is worth explaining in detail that a limiting shaft 10 is fixed inside the other opening 6, and a limiting sleeve 11 is provided on the sliding sleeve on the outer circumference of the limiting shaft 10. One end of the limiting sleeve 11 passes through the adjacent opening 6 and is fixed to the surface of the push plate 3. Since the limiting sleeve 11 can only slide along the outer circumference of the limiting shaft 10 on the inner cavity surface of the adjacent opening 6, it can limit the movement trajectory of the push plate 3 and make its movement smoother.

[0027] This solution has the following working process: in actual use, when the user operates the drone body 1 to the position where the sample needs to be transported, first adjust the distance between the storage box 2 and the ground according to whether the items transported inside the storage box 2 are fragile items. If they are fragile items, start the second motor 15 to enable one of the second threaded rods 17 to rotate. When one of the second threaded rods 17 rotates, it can drive one of the pulleys 22 to rotate, so that under the connection action of the connecting belt 23, the other pulley 22 can drive the other second threaded rod 17 to rotate. Since the external thread structures at both ends of the outer circumference of the second threaded rod 17 are arranged in opposite directions to each other and the inner cavity surface of the rod groove 16 can play a role of resisting and limiting the second threaded sleeve 18, when the second threaded rod 17 rotates, the internal thread structure of the inner wall of the second threaded sleeve 18 and the corresponding external thread structure on the outer circumference of the second threaded rod 17 can cooperate to change the distance between the second threaded sleeves 18 at two adjacent positions, thereby The connecting rod 19 can change its angle, so that the storage box 2 can change its height, so that the surface of the bottom of the storage box 2 can fit the ground. If the transported items are not easily damaged by falling, there is no need to start the second motor 15. Then, by starting the first motor 9, the first motor 9 can drive the first threaded rod 7 to rotate. Since the opening 6 can play a role of resistance and limit for the first threaded sleeve 8, the first threaded sleeve 8 can drive the push plate 3 to move in the horizontal direction under the cooperation between the internal thread structure of its inner wall and the external thread structure of the outer peripheral surface of the first threaded rod 7. The baffle plate 5 is driven to move under the connection of the connecting strip 4, so that the push plate 3 can push the sample inside the storage box 2 out of the storage box 2 to complete the unloading. After the unloading is completed, the first motor 9 is started and its output end is rotated in the opposite direction, so that the push plate 3 is reset, and the second motor 15 is started to rotate its output end in the opposite direction, so that the storage box 2 is lifted to prevent affecting the lifting and landing work behind the drone body 1.

[0028] According to the above working process, it can be known that after the sample is transported to the corresponding position by the drone body 1, the first motor 9 is started so that the push plate 3 and the baffle 5 can move in the horizontal direction, so that the push plate 3 can push the items placed in the storage box 2 out of the storage box 2, thereby achieving automatic unloading, thereby improving the efficiency of sample transportation by the sample delivery drone, thereby improving the practicality of the device, and starting the second motor 15 so that the spacing between the second threaded sleeves 18 at two adjacent positions changes, so that the angle of the connecting rod 19 can change, thereby reducing the spacing between the storage box 2 and the ground, thereby improving the safety of unloading when unloading certain fragile samples to avoid sample breakage, thereby further improving the practicality of the device.

[0029] Further Figure 4 As shown, it is worth explaining in detail that both ends of the bottom surface of the connecting seat 14 are provided with symmetrically distributed resistance holes 20, and a limiting rod 21 is slidably inserted inside the resistance hole 20. The bottom of the limiting rod 21 passes through the resistance hole 20 at the adjacent position and is fixed to the surface of the top of the storage box 2. When the storage box 2 moves in the vertical direction, the movement trajectory of the storage box 2 can be limited under the interference effect of the limiting rod 21 and the hole wall of the resistance hole 20 at the adjacent position, thereby making the vertical movement process of the storage box 2 smoother.

[0030] In summary: after the sample is transported to the corresponding position by the drone body 1, the first motor 9 is started so that the push plate 3 and the baffle 5 can move in the horizontal direction, so that the push plate 3 can push the items placed in the storage box 2 out of the storage box 2, thereby achieving automatic unloading, thereby improving the efficiency of sample transportation by the sample delivery drone, thereby improving the practicality of the device, and starting the second motor 15 so that the spacing between the second threaded sleeves 18 at two adjacent positions changes, so that the angle of the connecting rod 19 can change, thereby reducing the spacing between the storage box 2 and the ground, thereby improving the safety of unloading certain fragile samples to avoid sample breakage, thereby further improving the practicality of the device, and when the storage box 2 moves in the vertical direction, the movement trajectory of the storage box 2 can be limited under the interference effect of the limiting rod 21 and the hole wall of the adjacent position contact hole 20, thereby making the vertical movement process of the storage box 2 smoother.

[0031] The first motor 9 and the second motor 15 can be purchased on the market. The first motor 9 and the second motor 15 are equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it is not repeated in the specification.
