[0051] The dredging mechanism 5 includes a rotating shaft 501 that is rotatably installed on the equipment box 4, a driving motor 502 is provided at one end of the rotating shaft 501, and the driving motor 502 is fixedly installed on the outer wall of the seed mixing barrel 1 through a motor bracket 503, and the output shaft of the driving motor 502 is fixedly connected to the rotating shaft 501, and two reciprocating screws 504 are fixedly sleeved on the rotating shaft 501, and a reciprocating screw sleeve 505 is threadedly connected to the outer surface of the reciprocating screw 504, and a guide ring 506 is fixedly connected to the reciprocating screw sleeve 505, and a guide rod 507 is movably inserted inside the guide ring 506, and the guide rod 507 is fixedly connected to the equipment box 4, and a dredging rod 508 is also fixedly connected to the reciprocating screw sleeve 505, and the dredging rod 508 extends to the feeding port 3 at one end away from the reciprocating screw sleeve 505;

[0052] In actual application, the output end of the driving motor 502 is rotated to drive the rotating shaft 501 to rotate, thereby driving the reciprocating screw 504 to rotate, and under the limiting effect of the guide rod 507 and the guide ring 506 on the reciprocating screw sleeve 505, the reciprocating screw sleeve 505 moves back and forth along the axial direction of the reciprocating screw 504, thereby driving the dredging rod 508 to move back and forth in the feeding port 3, thereby achieving the effect of dredging the wheat in the feeding port 3, avoiding blockage of the wheat in the feeding port 3, and improving the feeding effect.

[0053] The stirring device includes a hollow shaft 601 that is rotatably installed at the bottom of the equipment box 4, and a plurality of hollow stirring rods 602 are fixedly connected to the hollow shaft 601. The hollow stirring rods 602 are provided with a plurality of medicine outlet holes 603, and a filter screen (not shown in the figure) is arranged inside the medicine outlet holes 603;

[0054] In practical applications, when the rotating shaft 501 rotates, the kinetic energy can be transmitted to the stirring device through the transmission assembly 7, so that the hollow stirring rod 602 rotates to stir the wheat in the seed dressing barrel 1, so as to evenly mix the wheat and the agent.

[0055] The top end of the hollow shaft 601 is rotatably connected to a medicine delivery branch pipe 9 via a sealed bearing. The other end of the medicine delivery branch pipe 9 is fixedly connected to a medicine delivery main pipe 804. A solenoid valve 10 is provided on the medicine delivery branch pipe 9.

[0056] A control panel 11 is provided on the front of the seed mixing barrel 1, and a feed pipe 12 is fixedly connected to the bottom of the seed mixing barrel 1, and a solenoid valve 3 13 is provided on the feed pipe 12. The control panel 11 is electrically connected to the drive motor 502, the water pump 802, the solenoid valve 1 808, the solenoid valve 2 10 and the solenoid valve 3 13 respectively;

[0057] In actual application, after the wheat in the seed dressing barrel 1 is finished being dressed, the solenoid valve 3 13 is opened through the control panel 11 to discharge the wheat in the seed dressing barrel 1 through the discharge pipe 12 .

[0058] Working principle: When in use, the staff first adds an appropriate amount of medicine into the medicine storage box 801 through the water injection port on the medicine storage box 801, and then the workers pour the wheat seeds to be mixed into the wheat storage frame 2, and the wheat slowly flows into the seed mixing barrel 1 from the feeding port 3 due to its own gravity;

[0059] When the wheat in the wheat storage frame 2 flows into the seed mixing barrel 1 through the feeding port 3, the driving motor 502 and the water pump 802 are started through the control panel 11, and the electromagnetic valve 1 808 is opened and the electromagnetic valve 2 10 and the electromagnetic valve 3 13 are closed. The water pump 802 extracts the medicine in the medicine storage box 801 through the medicine suction pipe 803, and sequentially transports it to the U-shaped tube 806 through the medicine delivery main pipe 804 and the medicine delivery branch pipe 1 805. Finally, the nozzle 807 sprays the medicine on the wheat in the falling process, so that the medicine is sprayed in the process of slowly feeding the wheat into the seed mixing barrel 1, and the wheat is initially mixed with medicine. Since the wheat is in a flowing state during the feeding process and is not accumulated, it is conducive to uniformly spraying the medicine on the wheat.

[0060] The output end of the driving motor 502 is rotated to drive the rotating shaft 501 to rotate, thereby driving the reciprocating screw 504 to rotate, and under the limiting effect of the guide rod 507 and the guide ring 506 on the reciprocating screw sleeve 505, the reciprocating screw sleeve 505 reciprocates along the axial direction of the reciprocating screw 504, thereby driving the dredging rod 508 to reciprocate in the feeding port 3, thereby achieving the effect of dredging the wheat in the feeding port 3, avoiding the wheat in the feeding port 3 from being blocked, and improving the feeding effect;

[0061] And through the setting of the transmission component 7, the kinetic energy on the dredging mechanism 5 can be transmitted to the stirring mechanism 6, thereby driving the hollow stirring rod 602 to rotate and stir the wheat in the seed mixing barrel 1. When all the wheat in the wheat storage frame 2 flows into the seed mixing barrel 1, the solenoid valve 1 808 is closed and the solenoid valve 2 10 is opened. The medicine in the medicine delivery main pipe 804 is successively transported to the hollow stirring rod 602 through the medicine delivery branch pipe 2 9 and the hollow shaft 601, and finally flows out from the medicine outlet hole 603 on the hollow stirring rod 602, thereby realizing the secondary mixing of the wheat. Moreover, since the hollow stirring rod 602 is in a rotating state, it is beneficial to evenly add the medicine to the wheat in the seed mixing barrel 1, avoid uneven addition of medicine and increase the burden of subsequent uniform seed mixing, and improve the uniformity and efficiency of seed mixing.

[0062] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the transmission assembly 7 includes a driving bevel gear 701 and a driven bevel gear 702, the driving bevel gear 701 is fixedly sleeved on the rotating shaft 501, and the driven bevel gear 702 is fixedly sleeved on the hollow shaft 601, the outer surfaces of the driving bevel gear 701 and the driven bevel gear 702 are meshed, and the driving bevel gear 701 and the driven bevel gear 702 are both located in the equipment box 4.

[0063] Through the arrangement of the transmission assembly 7, when the rotating shaft 501 rotates, the active bevel gear 701 can be driven to rotate synchronously, and the driven bevel gear 702 meshing therewith can be driven to rotate synchronously, thereby driving the hollow stirring rod 602 to rotate to stir the wheat in the seed mixing barrel 1, so as to facilitate uniform mixing of the wheat and the agent.

[0064] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
