[0033] In an optional implementation of the embodiment of the utility model, as Figure 1 As shown, a counting sensor is installed in the feed port 21 for counting the fallen seeds.

[0034] In an optional implementation of the embodiment of the utility model, as Figure 3 As shown, the spring piece 6 is made of stainless steel and has good elasticity, fatigue limit, impact toughness and temperature resistance.

[0035] In an optional implementation of the embodiment of the utility model, as Figure 8 As shown, at least four paddles 7 are provided, and the intervals between the paddles 7 are equal.

[0036] Working principle: When the utility model is in use, the number of seeds that fall can be accurately controlled. The lower end of the existing seeder is connected to the feed port 21, so that the seeds first enter the device through the feed port 21. The seeds that fall from the seeder may be more or less. For example, four seeds are used as the standard. When the seeds fall from the seeder into the feed port 21, the sensor in the feed port 21 counts the fallen seeds. Before using the device, a certain amount of seeds is added from the storage port 22, so that the seeds are stored in the space above the inclined baffle 5.

[0037] When the sensor counts that exactly four seeds have fallen, the four seeds are arranged in the drainage groove 4 and blocked by the lower baffle 11. When the equipment moves to the planting location, the electric push rod 12 is started, driving the lower baffle 11 to slide outward, thereby opening the opening, allowing the four seeds to fall into the ground through the discharge opening 23.

[0038] When the sensor counts that less than four seeds have fallen, the seeds are arranged in the drainage groove 4 and are blocked by the lower baffle 11. At this time, the stored seeds are arranged in the channel between the lower side of the spring 6 and the inner wall of the shell 1, and the lowest seed is stuck by the spring 6. At this time, the motor I 15 is started, driving the turntable 8 to rotate, and the paddle 7 on the turntable 8 rotates accordingly. The lowest paddle 7 rotates to the seed at the bottom of the storage space. At this time, the paddle 7 is squeezed and contracted by the arc-shaped rack 19 and does not pop out. Then the motor II 16 is started to drive the gear 18 to rotate, and the gear 18 drives the arc-shaped rack 19 to rotate, so that the arc-shaped rack 19 is separated from the lowest paddle 7, so that the paddle 7 is ejected under the action of the compression spring 10, thereby inserting The seeds in the drainage groove 4 fall into the gap between the outermost seeds under the spring piece 6, and then the lower baffle 11 is opened under the drive of the electric push rod 12, and the seeds in the drainage groove 4 fall down. Then, the turntable 8 continues to rotate under the drive, so that the pop-up paddle 7 drives the seeds under the spring piece 6 to be moved to the bottom of the drainage groove 4, so that the seeds in this storage bin fall together with the seeds in the drainage groove 4. If there are two seeds missing, the paddle 7 adjacent to the bottom paddle 7 is also popped out, and one seed in the storage bin is pulled out, and then the turntable 8 rotates a full circle to reset the paddle 7. When resetting, when the paddle 7 rotates to the position of the storage bin, it will be squeezed and contracted by the arc-shaped rack 19 along the inclined surface of the arc-shaped rack 19.

[0039] When the sensor counts more than four seeds dropped, the seeds are arranged in the drainage groove 4 and blocked by the lower baffle 11. At this time, the excess seeds need to be removed. At this time, the motor I 15 drives the turntable 8 to rotate, thereby driving the paddle 7 to rotate. When the paddle 7 rotates to the outside of the outermost seed under the spring 6, the motor II 16 starts, driving the gear 18 to rotate, thereby driving the arc rack 19 to rotate. The arc rack 19 is separated from the squeeze on the paddle 7, and the paddle 7 pops out under the action of the compression spring 10. Then the turntable 8 continues to rotate, driving the paddle 7 to rotate, and the paddle 7 pokes the seed at the bottom of the drainage groove 4. Then the arc rack 19 is reset, so that the rear paddle 7 does not pop out when passing under the drainage groove 4, so that a seed moves along the arc plate 3 and The channel on the inner wall of the shell 1 rotates, and when the paddle 7 passes the upper end of the arc plate 3, due to inertia and the slightly accelerated rotation of the turntable 8, the seeds moved by the paddle 7 fall back into the storage bin above the inclined baffle 5, so that the excess seeds in the drainage groove 4 are removed and recovered into the storage compartment, and then the lower baffle 11 is opened, and the remaining four seeds fall into the ground through the discharge port 23; if there are two or more extra seeds, the number of the paddles 7 that pop out from the bottom of the drainage groove 4 is consistent with the number of extra seeds, and after the excess seeds are pulled out one by one, the arc-shaped rack 19 is reset so that the rear paddle 7 does not pop out; in this way, the precise control of the number of seeds is completed, so that only the specified number of seeds falls, which greatly increases the planting accuracy.
