During operation, the invention rotates along the direction shown by the arrow in the attached figure 1, seeds are added into the seed bin 18, and as the synchronous component is arranged between the main disc 1 and the core disc 5, the pawl 24 is positioned in the clamping groove 23-4, and when the main disc 1 rotates, the core disc 5 is driven to rotate synchronously (the rotating direction of the main disc 1 is opposite to the inclined direction of the inclined surface 23-2); meanwhile, the core plate 5 drives the finger clamp body 6 to rotate, when the roller 6-4 of the finger clamp body 6 is in contact with the cam plate 7 and moves from the first transition section 7-4 to the seed filling section 7-3, the height of the working surface of the cam plate 7 is gradually reduced, the roller 6-4 gradually moves backwards under the action of the torsion spring 6-3 to enable the opening of the seed clamping cavity 8 to be gradually reduced, when the finger clamp body 6 moves to the seed filling section 7-3, seeds in the seed bin 18 enter the seed clamping cavity 8, the finger clamp body 6 continuously moves to be separated from the cam plate 7, further the finger clamp body 6 clamps the seeds in the seed clamping cavity 8 under the action of the torsion spring 6-3 of the finger clamp body and moves to the second transition section 7-1 under the action of the core plate 5, when the finger clamp body 6 enters the seed discharging section 7-2 through the second transition section 7-1, and the height of the working surface of the cam plate 7 is gradually increased, the rollers 6-4 move forward under the action of the cam plate 7, so that the opening of the seed clamping cavity 8 is increased, seeds in the seed clamping cavity 8 fall to the seed dropping port 16, then the seeds enter the inner channel 36 and enter the outer channel 33 through the communicating port, the seed guide groove rotates along with the main disc 1, the seeds also rotate in the outer channel 33, and when the corresponding hole forming device 35 rotates to the working position (namely, the lower end of the main disc 1), the seeds enter the seed inlet of the corresponding hole forming device 35 from the outer channel 33, so that the seeding of the seeds is realized.

The measuring module 31 transmits a signal to the control module, if no seed is detected in the seed clamping cavity 8, the control module controls the driving device, the driving device drives the core disc 5 to rotate (the rotation direction of the core disc 5 is unchanged), the core disc 5 rotates in the same direction relative to the main disc 1, the pawl 24 moves in the inclined direction of the inclined surface 23-2 and is separated from the clamping groove 23-4, so that the power transmission between the main disc 1 and the core disc 5 is cut off, when the rotation amount of the core disc 5 meets the requirement of crossing the finger clamp body 6 without the seed, the driving device stops driving the core disc 5, the pawl 24 enters the clamping groove 23-4 again under the action of the return spring 25, the core disc 5 continuously rotates synchronously under the action of the main disc 1, the phenomenon of missing seed in the seeding process can be effectively avoided, and the seeding quality is effectively improved.
The arrangement of the synchronous components not only realizes the power transmission connection of the synchronous rotation of the main disc 1 and the core disc 5, but also ensures the power transmission cut-off when the core disc 5 rotates in the same direction relative to the main disc 1, so that the invention has flexible and convenient operation; in addition, the main disc 1 drives the core disc 5 to rotate through the pawl 24 and the synchronous seat 23, so that the core disc 5 is effectively prevented from rotating reversely; the arrangement of the return spring 25 effectively realizes that the pawl 24 is clamped in the clamping groove 23-4 when the main disc 1 and the core disc 5 synchronously rotate, ensures the power transmission connection of the main disc and the core disc 5, and simultaneously effectively realizes the conversion from the state of separating from the clamping groove 23-4 to the clamping state after the rotation speed adjustment of the core disc 5 is completed, thereby ensuring the continuity of the operation of the invention; the arrangement of the finger clamp body 6 effectively improves the accurate seed discharge, and avoids the waste of seeds caused by the outflow of a large amount of seeds from the seed discharge port 16 in the operation process; the arrangement of the cam plate 7 controls the position of the cam through the different heights of the working surface of the cam plate to further realize the size of the opening of the seed clamping cavity 8, and realizes the resetting and clamping of the finger clamping plate 6-1 through the torsion spring 6-3, so that the operation processes of seed filling, seed clamping and seed discharging are smooth and continuous, and the seeding precision is effectively improved; the arrangement of the one-way blocking curtain 15 effectively avoids the phenomenon that seeds at the seed filling section 7-3 flow back to the seed unloading section 7-2, and then a large amount of seeds fall from the seed discharging port 16. According to the requirement, the detection module can also adopt a switch which can be controlled to be opened or closed by the roller 6-4, namely when no seeds exist in the seed clamping cavity 8, the roller 6-4 can be in contact with the switch to close the switch so that the control module controls the driving device to operate, and when seeds exist in the seed clamping cavity 8, the roller 6-4 is not in contact with the switch so that the driving device is not triggered to operate.

As shown in fig. 1 and 2, a ratchet mechanism is further provided between the driving wheel 21 and the output shaft of the motor 20, which enables the motor 20 to drive the driving wheel 21 in one direction. When the rotation speed of the core disc 5 needs to be adjusted, the output shaft of the motor 20 transmits power to the driving wheel 21 under the action of the ratchet mechanism, and when the core disc 5 is driven by the main disc 1 to synchronously rotate, the power transmission between the output shaft of the motor 20 and the driving wheel 21 is cut off by the ratchet mechanism, so that the motion interference between the output shaft of the motor 20 and the output shaft of the motor 20 when the main disc 1 drives the core disc 5 to rotate is avoided.
