[0037] Brief description of the use process: when in use, the seeds are stored in the seed storage box 2, the motor 31 and the power fan 11 are connected to the power supply, and they are powered on to work, the power fan 11 rotates, and the spraying pipe 10 blows air outward through the connection of the rotating joint 91, and then the inside of the spraying pipe 10 will generate a traction negative pressure toward the nozzle of the spraying pipe 10 according to the principle of aerodynamics, and then the inside of the delivery pipe 12 has an attraction for supplying air to the spraying pipe 10; the motor 31 drives the driving wheel 33 to rotate through the reducer 32, and the driving wheel 33 drives the seed metering device 4 to start working through the transmission chain 5, and the seed metering device 4 discharges the seeds in the seed storage box 2 to the seed discharge port and reaches the delivery pipe 12. According to the above principle, the inside of the delivery pipe 12 has an attraction for supplying air to the spraying pipe 10, so the delivery pipe 12 will transport the seeds discharged by the seed metering device to the spraying pipe 10, and the seeds are sprayed out from the nozzle of the spraying pipe 10 to complete the spraying operation.

[0038] At the same time, the seeding tube 10 will also perform reciprocating deflection to realize multi-directional seeding operation. At this time, the rotation of the driving wheel 33 will drive the rotating shaft 147 thereon to perform reciprocating rotation, and then the connecting rod 6 that rotates on the rotating shaft 147 follows the reciprocating motion, and then the connecting rod 6 drives the reciprocating rod 72 in the reversing device 7 to perform reciprocating rotation, and then drives the transverse shaft 73 to perform reciprocating rotation, and the transverse shaft 73 drives the driving gear 8 to perform reciprocating rotation through the vertical shaft 74, the first bevel gear 75, and the second bevel gear 76. The driving gear 8 drives the rotating joint 91 to rotate reciprocatingly through the ring gear 92, and then the seeding tube 10 connected to the rotating joint 91 will also perform reciprocating deflection, and then a multi-angle seeding operation in the fan-shaped area is performed.

[0039] The rotation amplitude of the connecting rod 6 near one end of the rotating shaft 147 can be adjusted by adjusting the eccentric distance of the rotating shaft 147, thereby adjusting the rotation amplitude of the reciprocating rod 72 and the transverse shaft 73 connected to the connecting rod 6. Combined with the above-mentioned deflection principle, the rotation amplitude of the driving gear 8 can be adjusted, thereby adjusting the rotation amplitude range of the spraying tube 10 to achieve angle adjustment of multi-angle spraying.

[0040] When adjusting the eccentric distance of the rotating shaft 147, loosen the fastening bolt 148, and then use a wrench to tighten the bolt head 144. The bolt head 144 drives the screw rod 143 to rotate. Because the second slider 146 is embedded in the slide groove 145 and cannot rotate, the rotating screw rod 143 will drive the second slider 146 to move linearly in the slide groove 145, thereby adjusting the distance between the second slider 146 and the axis of the driving wheel 33, and then adjusting the eccentric distance of the rotating shaft 147.

[0041] When it is necessary to adjust the amount of seeding, by setting the wheel slot box 41, the wheel slot opening 42, the slot wheel shaft 43, the driven wheel 44, the wheel slot 45, the first slider 46 and the adjusting nut 47, the wheel slot box 41 is set at the lower end of the seed storage box 2, and the wheel slot opening 42 is set corresponding to the seed storage box 2. When dropping is required, the external motor transmits power to the driven wheel 44 through chain drive, and then the driven wheel 44 drives the slot wheel shaft 43 to rotate, and then the wheel slot 45 rotates, so that the seeds in the seed storage box 2 can be discharged from the wheel slot opening 42, and then the adjusting nut 47 adjusts the position of the first slider 46, and then cooperates with the wheel slot 45 to affect the size of the wheel slot opening 42, which can affect the amount of seeding.

[0042] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
