[0047] The second embodiment is mainly different from the first embodiment in that the stirring assembly 6 comprises a stirring shaft 61 rotationally arranged in the storage box 5, a plurality of groups of stirring columns 62 are fixedly connected to the outer surface of the stirring shaft 61, and the other end of the stirring shaft 61 penetrates the sealing cover 15 and is fixedly connected with a first motor 63.

[0048] The scraping assembly 7 comprises a group of fixed blocks 71 fixedly installed at the lower end of the base 1, a mounting column 74 rotationally connected between the group of fixed blocks 71, limit blocks 72 fixedly connected to the two ends of the mounting column 74, the limit blocks 72 rotationally connected to the fixed blocks 71, and a grab rake 75 for carding the seeds after being fed fixedly connected to the mounting column 74.

[0049] The fixing block 71 and the limiting block 72 are both provided with a plurality of thread holes 73 distributed at equal intervals, the thread hole 73 provided on the fixing block 71 is provided with a limiting bolt 76, the other end of the limiting bolt 76 is engaged with a nut 77, one end of the nut 77 abuts against one side of the limiting block 72; wherein, the mounting column 74 is rotated along the axial direction, and then the limiting bolt 76 and the nut 77 are used to fix the mounting column 74, so that the included angle between the rake 75 on the mounting column 74 and the ground can be changed.

[0050] The surface of the quantitative roller 42 is fixedly provided with a group of symmetrically arranged sliding grooves 46, the bottom of the storage box 5 is fixedly connected with a discharging port 12, the outside of the discharging port 12 is fixedly connected with a group of symmetrically arranged connecting clamping blocks 13, the connecting clamping blocks 13 are slidingly clamped in the sliding grooves 46, so that the quantitative roller 42 is prevented from being separated from the lower side of the discharging port 12 during sliding.

[0051] The bottom of the base 1 is fixedly connected with four traveling wheels 8.

[0053] After the first motor 63 starts, the stirring shaft 61 is driven to rotate, and the multiple groups of stirring columns 62 fixedly connected to the outer surface of the stirring shaft 61 are rotated. During the rotation of the stirring shaft 61, the stirring columns 62 stir the rice seeds in the storage tank 5 in all directions. Since the stirring columns 62 are uniformly distributed, the seeds in the storage tank 5 can be fully stirred in each area, preventing the seeds from caking due to long-term standing, moisture, and other factors, and promoting the seeds to flow continuously and uniformly to the discharge port 12 below the storage tank 5, stably supplying the seeds to the quantitative assembly 4. The seedling paper moves under the drive of the paper conveying device, and when the quantitative assembly 4 completes the seed feeding, the seedling paper moves the seeds to below the scraping assembly 7. In the scraping assembly 7, the rake 75 on the mounting column 74 contacts the seeds. By loosening the limiting bolts 76 and nuts 77, the mounting column 74 can be rotated along the axis of the mounting column 74, adjusting the included angle between the rake 75 and the ground. After adjusting to the appropriate angle, the limiting bolts 76 and nuts 77 are tightened to fix the mounting column 74. The rakes 75 at different angles can comb the seeds at different intensities and in different ways, dispersing the accumulated seeds and making the seeds evenly distributed on the seedling paper. The symmetrical sliding grooves 46 on the surface of the quantitative roller 42 cooperate with the connecting blocks 13 outside the discharge port 12 at the bottom of the storage tank 5. During the rotation of the quantitative roller 42, the connecting blocks 13 slide along the sliding grooves 46, so that the quantitative roller 42 always remains directly below the discharge port 12 of the storage tank 5. In this way, when the quantitative cylinder 44 on the quantitative roller 42 receives the seeds, it can accurately receive the seeds falling from the discharge port 12, ensuring the accuracy of the quantitative process, preventing the quantitative roller 42 from deviating during rotation and moving away from below the discharge port 12, and ensuring the continuity and stability of the seeding work. The travel wheels 8 at the four corners of the bottom of the base 1 enable the seeding machine to move flexibly in the field, facilitating the operator to transport the seeding machine to different planting areas for operation. The operator can hold the handle 14 on one side of the base 1 and push or pull the seeding machine to control its moving direction and speed, which is simple and convenient to operate.
