[0030] See also Figure 5 The conduction assembly 64 in this embodiment includes a conduction bar 641 installed at the lower end of the connecting tube 61 and connected to the bottom of the discharge ports 63 on both sides, a servo motor 642 installed at the middle of the lower end of the conduction bar 641, and a first bevel gear 643 installed at the upper end of the servo motor 642.

[0033] To further explain, a corresponding hollow space is opened inside the feeding tray 656, and the hollow spaces opened inside the feeding tray 656 are all connected with the guide opening 657, so as to ensure the efficient combination of the feeding tray 656 and the guide opening 657 and realize uniform rotating spreading activity.

[0034] Here’s how it works:

[0035] When the drone for sowing Chinese milk vetch is to be used, the storage box 2 provided at the upper end of the drone body 1 can be opened so that the storage box 2 can be used to store the Chinese milk vetch seeds in advance. After the Chinese milk vetch seeds are placed in preparation, the entire operation of the drone body 1 can be realized through the remote control device. In this way, the combination of the brushless motor 4 and the fan blades 5 provided at the four sides of the outer end of the drone body 1 can be used to realize the flying sowing activity.

[0036] In order to improve the smoothness and uniformity of sowing, an anti-blocking intermittent material guiding device 6 is provided at the lower end of the drone body 1 to realize intermittent discharging and uniform sowing of seeds, that is, the motor 624 provided inside the intermittent component 62 is driven in advance to make the motor 624 realize the rotation of the turntable 622 connected to the front side, so that the turntable 622 can rotate along the inner circumference of the limit frame 621, and when the receiving groove 623 opened at one of the four sides of the turntable 622 is opposite to the top opening of the limit frame 621 and stops rotating, the astragalus seeds stored in the storage box 2 will The seeds are then fed to the feeder 623, which is a container 624, and the feeder 623 is moved to the feeder 623. The feeder 623 is moved to the feeder 623, which is a container 624, and the feeder 623 is moved to the feeder 623. The feeder 623 is moved to the feeder 623, which is a container 624. The feeder 623 is moved to the feeder 623, which is a container 624. The feeder 623 is moved to the feeder 623, which is a container 624. The feeder 623 is moved to the feeder 623, and the feeder 623 is moved to the feeder 623.

[0037] When the milk vetch seeds are poured from the discharge port 63 into the conductive strip 641 of the conductive assembly 64, the servo motor 642 installed in the middle of the lower end of the conductive strip 641 will drive and realize the rotation of the first bevel gear 643 connected to the top, so that the second bevel gears 644 meshingly connected to the left and right sides of the upper end will rotate at the same time, and drive the corresponding feeding rod 645 connected in the middle to rotate. Since the feeding rod 645 is integrally installed with a spiral strip on the outside, the feeding rod 645 can be rotated. The astragalus seeds that enter the conductive strip 641 are transmitted laterally to realize the diversion transmission sowing activity, so that the seeds can be sown in a dispersed manner, and the occurrence of a large amount of seed sowing and accumulation phenomenon is reduced. When transmitted to the outermost side of the conductive strip 641, they will fall into the feeding tray 656 provided inside the sowing component 65. In this way, the astragalus seeds can be dispersed and evenly sown by cooperating with multiple guide ports 657 equidistantly provided in the hollow part of the feeding tray 656 and the outside, so as to improve the efficiency and quality of astragalus seed sowing;

[0038] In order to further improve the sowing efficiency, a sowing assembly 65 is installed at the bottom of the side of the transmission assembly 64 to drive the feeding plate 656 in a circular manner, so that the feeding plate 656 can rotate and sow, thereby improving the sowing diversity. That is, when the feeding rod 645 rotates, the main bevel gear 651 connected to the side can be rotated, so that the auxiliary bevel gear 652 engaged with the bottom of the main bevel gear 651 can rotate accordingly, and the driving wheel 653 corresponding to the lower end can be driven, and the driving wheel 653 connected to the driving wheel 653 can be driven. The outer belt 654 will realize the rotation of the driven wheel 655 connected to the other side, so that the feeding plate 656 connected to the middle part of the driven wheel 655 will rotate in a circle. Therefore, the milk vetch seeds entering the feeding plate 656 can be quickly thrown out from the guide port 657 opened on the outside due to the centrifugal force of the rapidly rotating feeding plate 656, so as to speed up the sowing efficiency and uniformity of the milk vetch seeds, thereby achieving the advantages of the milk vetch seed assisted centrifugal rotation sowing.

[0039] The utility model provides an unmanned aerial vehicle for sowing astragalus, which is provided with an anti-blocking intermittent material guiding device 6, that is, the intermittent rotation and receiving cooperation of the limiting frame 621, the turntable 622 and the receiving groove 623 arranged inside the intermittent component 62 can realize the intermittent receiving and transmission of astragalus seeds, and reduce the occurrence of astragalus seed discharge blockage phenomenon, and a conduction component 64 is provided, that is, through the meshing transmission of the first bevel gear 643 and the second bevel gear 644, a feeding rod 645 with a spiral strip can be quickly rotated to conduct seeds for dispersed sowing, and a sowing component 65 is provided, that is, the feeding rod 645 can synchronously drive the main bevel gear 651 to rotate, thereby indirectly realizing the transmission of the driving wheel 653, the belt 654 and the driven wheel 655, thereby, the feeding plate 656 can rotate and cooperate with the guide port 657 opened on the outside to assist the rotation sowing cooperation, thereby achieving the advantages of the auxiliary centrifugal rotation sowing cooperation of astragalus seeds.
