As shown in fig. 2 and fig. 3, the hopper 1 is a trapezoidal hopper 1, the upper and lower openings form a feeding inlet 101 and a discharging outlet 102, a sowing wheel 2 is disposed at the discharging outlet 102, the sowing wheel 2 has a plurality of grooves 201 on the side surface opposite to the discharging outlet 102 for receiving the seeds falling from the discharging outlet 102 and delivering the seeds to the seedling tray, thereby completing the sowing process. During this period, the sowing wheel 2 is driven to rotate by the sowing driving mechanism. Specifically, seeding actuating mechanism includes one and passes and drive seeding wheel 2's axis of rotation 4, and its connected mode can dismantle fixed connection's mode or integrated into one piece's mode through key-type connection etc. and it directly drives seeding wheel 2 and rotates, sets up a drive shaft 6 parallel with seeding wheel 2 axis in addition, and by the drive rotation of driving piece such as motor, drive shaft 6 passes through the interthaft drive structure drive seeding axis of rotation 4 rotations such as chain drive, gear drive or belt drive. In above-mentioned seeding in-process, because the size of seed with arrange the difference, when seeding wheel 2 rotated, the seed blocked in recess 201 easily, can cause the omission of seeding, still can reduce seeding efficiency.

For this reason, this embodiment sets up runner brush 3 in one side of seeding wheel 2 for brush the remaining seed in the recess 201, and during, runner brush 3 is rotated by the drive of the driving mechanism of brushing kind, and the drive mechanism of brushing kind includes a brush kind axis of rotation 5 that passes and drive runner brush 3, and its connected mode can be through the mode or the mode of integrated into one piece of key-type connection etc. can dismantle fixed connection, and brush kind axis of rotation 5 directly drives runner brush 3 and rotates.

In a possible embodiment, the sowing rotary shaft 4 and the seed brushing rotary shaft 5 are driven to rotate by respective corresponding driving members.

In the practical work of the present embodiment, it is found that due to the fact that the sizes of the grooves 201 of the sowing wheel 2 and the seeds are different, the arrangement of the seeds in the grooves 201 is not uniform enough, and even a large-sized gap hidden under the seeds exists in the grooves 201, so that the density of the seeds sowed on the seedling tray is uneven, and the germination rate is reduced. Therefore, as shown in fig. 3 and fig. 5, in the present embodiment, a plate-shaped brush 7 is detachably disposed at the boundary between the sowing wheel 2 and the discharge hole 102, and is parallel to the length direction of the groove 201, and is used for brushing the seeds stacked in the groove 201 uniformly, so that the uniformity of sowing on the final seedling tray can be improved, and further, the germination rate can be improved. The plate-shaped brush 7 used in the method can be composed of a base plate 701 and bristles 702 arranged on the base plate 701, the bristles 702 are made of soft materials, and the seeds in the groove 201 can be prevented from colliding with the hopper 1 to be damaged, so that the effect of protecting the seeds is achieved.

In order to keep the bristles 702 at a proper angle with the groove 201, the base plate 701 is attached to the inclined side wall of the discharge port 102 of the hopper 1 at a side opposite to the sowing wheel 2, so that the seeds in the groove 201 can be brushed more smoothly and the seeds can be protected more sufficiently.

In another possible embodiment, due to the different sizes of the seeds, when the sizes of the seeds are changed, the plate-shaped brush 7 in the original position cannot play a role of brushing the seeds and may block the falling of the seeds. For this purpose, the present embodiment further comprises a lifting driving mechanism 8 disposed on the inclined sidewall of the discharge port 102 of the hopper 1, which can drive the plate-shaped brush 7 to lift along the sidewall of the hopper 1, so as to adjust the distance between the plate-shaped brush 7 and the groove 201 according to the variation of the size of the seeds.

Specifically, the lifting driving mechanism 8 comprises a connecting plate 801 which slides on the side wall of the hopper 1 to lift, the connecting plate 801 is driven to lift by a gear rack structure 802, and the plate-shaped brush 7 is fixedly connected below the connecting plate 801, so that the lifting of the plate-shaped brush 7 is realized, the height of the plate-shaped brush 7 can be adjusted according to seeds with different sizes, and the plate-shaped brush 7 can play a better role in brushing uniform seeds and protecting the seeds.

In addition, in order to make the connection plate 801 stably slide up and down on the sidewall of the hopper 1, a guide structure 803 is provided between the connection plate 801 and the sidewall of the hopper 1 to restrict the stable up and down movement of the connection plate 801. In a possible embodiment, the guide structure 803 comprises a guide groove 8031 provided on the connecting plate 801, and a sliding portion 8032 provided on the inclined side wall of the hopper 1, the sliding portion 8032 sliding in the guide groove 8031; in another possible embodiment, the guiding structure 803 may also be a sliding portion 8032 provided on the connecting plate 801 and a guiding groove 8031 provided on the inclined side wall of the hopper 1.
