[0002] Rapeseed, also known as oil cabbage and bitter vegetable, is rich in nutrients and high in vitamin C. Rapeseed generally grows in relatively humid climates. Rapeseed flowers can be eaten when they are in bud. When rapeseed flowers are in full bloom, they are a beautiful landscape and can be developed into a tourist attraction. The rapeseed harvested after the flowers wither can be used to extract oil.

[0032] Here’s how it works:

[0033] When the present rapeseed sowing drone is to be used, the rapeseed seeds can be placed by unscrewing the screw cap 7 provided at the upper end of the storage barrel 6. After the rapeseed seeds are placed, the seeds can be introduced into the spreader 9 through the discharge pipe 8 provided at the lower end of the rear side of the storage barrel 6 to prepare for sowing. In this way, the staff can drive the drone body 1 as a whole through the remote control. Thus, with the rotation cooperation of the brushless motors 4 and the rotors 5 installed at the corresponding outer ends of the six arms 2, the drone body 1 can be remotely controlled to realize the flight sowing activities as a whole.

[0034] In order to ensure uniform seed sowing, an anti-blocking uniform sowing device 11 is provided on the outer side of the lower end of the spreader 9 to achieve uniform seed sowing. First, during the flying sowing activity, the motor 114 provided inside the lower end of the connecting shell 111 can be driven to rotate the auger 118 connected to the top. In this way, the seeds inside the spreader 9 can quickly enter the hollow part inside the connecting shell 111 through the rotation of the auger 118 to reduce the occurrence of seed blockage and accumulation. When the seeds enter the lower end of the hollow part inside the connecting shell 111, some seeds can pass through a plurality of guide grooves 119 equidistantly provided inside the connecting shell 111, and from the plurality of guide grooves 119 relatively connected outside The guide tube 113 is led out, thereby achieving uniform material guiding and sowing, so that the seeds are evenly sown and the occurrence of disorderly sowing is reduced. Secondly, when the transmission shaft 115 rotates, the cam 1171 provided inside the stirring structure 117 can be driven by the synchronous rotation with the auxiliary rotation cooperation of the bearing 116 provided on the outer side of the lower end. When the cam 1171 rotates, the stirring rods 1172 symmetrically installed on both sides of the lower end of the cam 1171 will correspondingly realize the stirring of the remaining seeds that fall out of the lower end of the connection shell 111, so that the remaining seeds evenly enter the corresponding guide groove 119 to achieve uniform sowing cooperation, ensure that the rapeseed seeds are fully and evenly sown, thereby achieving the advantages of anti-blocking feeding and uniform sowing of rapeseed seeds.

[0035] A quick-connect assembly 112 is provided at the upper end of the connecting shell 111, so that the anti-blocking uniform spreading device 11 can be quickly disassembled and assembled with the bottom of the spreader 9 to meet the use of different situations. That is, when disassembly is required, the worm 11a1 provided inside the rotating transmission structure 11a can be rotated to rotate the worm 11a1, so as to realize the rotation of the first worm gear 11a2 and the second worm gear 11a3 that mesh with the left and right sides respectively. In this way, the first worm gear 11a2 and the second worm gear 11a3 are synchronously rotated in the opposite direction, and the front side of the first worm gear 11a2 and the second worm gear 11a3 is rotated. The connecting arms 1122, which are correspondingly provided with the first transmission bar 11a4 and the second transmission bar 11a5 for transmission connection, will realize synchronous opposite transverse movement, thereby, the moving rods 1123, which are correspondingly fastened to the outer ends of the connecting arms 1122 on both sides, can realize transverse movement through the guide rods 1124 and the guide frames 1125 for guiding and supporting, so that the pressure strips 1126 fastened to the middle of the moving rods 1123 can be moved out of the lower end opening of the spreader 9 to realize the locking release movement, so that the anti-blocking uniform spreading device 11 can be quickly disassembled from the drone body 1 as a whole;

[0036] When reassembly is required, the docking plate 1121 can be docked with the lower opening of the spreader 9 in advance, and then the worm 11a1 can be rotated again to make the first worm gear 11a2 and the second worm gear 11a3 cooperate with the first transmission bar 11a4 and the second transmission bar 11a5 installed on the front side to relatively move the connecting arms 1122 on both sides. In this way, the moving rods 1123 on both sides can make the corresponding fastened pressure strip 1126 in the middle part move back into the lower opening of the spreader 9 to achieve mutual clamping and locking, so that the drone body 1 and the anti-blocking uniform spreading device 11 can be quickly combined and connected, thereby achieving the advantage of convenient disassembly and assembly of the drone body 1 and the anti-blocking uniform spreading device 11.

[0037] The utility model provides a drone for spreading green manure rapeseed, which is provided with an anti-blocking uniform spreading device 11, that is, when the transmission shaft 115 is rotated, the auger 118 can smoothly conduct the rapeseed seeds, so that the seeds pass through the conduit 113 and the guide groove 119 to achieve uniform external guidance and spreading. Secondly, a stirring structure 117 arranged on the outer side of the transmission shaft 115 will run synchronously to stir the seeds, so that the seeds evenly enter the guide groove 119 to achieve uniform spreading activities, thereby achieving the advantages of anti-blocking feeding and uniform spreading of rapeseed seeds, and a quick-connect component 112 is provided, that is, under the transmission of the internal transmission structure 11a, the relative or opposite horizontal movement of the moving rods 1123 on both sides can be indirectly achieved, so that the pressure strips 1126 arranged on both sides can be conveniently moved outward or inward, so that the drone body 1 and the anti-blocking uniform spreading device 11 can be quickly disassembled and assembled, thereby achieving the advantages of convenient disassembly and assembly of the drone body 1 and the anti-blocking uniform spreading device 11.
