DETAILED DESCRIPTION

[0024] The technical scheme in the utility model embodiments will be clearly and completely described below in conjunction with the utility model embodiments, and obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments, based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0025] Embodiment 1

[0026] Referring to Figures 1-3The rice precision seeding device comprises a seeding box 1, a precision seeding conveyor belt 7, a fence unit, a seedling tray conveyor belt 10 and a seedling tray 8.

[0027] The seeding box 1 is a container with openings at the top and bottom, is arranged above the starting end of the upper surface of the precision seeding conveyor belt 7 in the movement direction, and is provided with a draw plate 9 at the bottom for controlling the amount of seed flow.

[0028] The surface of the precision seeding conveyor belt 7 is provided with a plurality of rows of seed holes 6 arranged in parallel and distributed at equal intervals. In this embodiment, the number of seed holes 6 in each row is nine, and the number of seed holes 6 can also be adjusted according to specific needs in actual use. The arrangement direction of each row of seed holes 6 is perpendicular to the movement direction of the precision seeding conveyor belt 7. Two pairs of support columns 11 are fixed on both sides of the precision seeding conveyor belt 7 to support the precision seeding conveyor belt 7, and one pair of support columns 11 extends upward and is connected to both sides of the seeding box 1 to fix the seeding box 1 above the precision seeding conveyor belt 7.

[0029] The fence unit comprises two fence plates 2 arranged on both sides of the precision seeding conveyor belt 7 to limit and guide the seeds on the precision seeding conveyor belt 7.

[0030] The seedling tray conveyor belt 10 is arranged directly below the precision seeding conveyor belt 7. The seedling tray 8 is placed on the seedling tray conveyor belt 10. The width of the seedling tray conveyor belt 10 matches the width of the precision seeding conveyor belt 7, and the movement direction of the upper surface is consistent with the movement direction of the upper surface of the precision seeding conveyor belt 7. The length of the seedling tray conveyor belt 10 is longer than the length of the precision seeding conveyor belt 7, so that the seedling tray conveyor belt 10 extends beyond the tail end of the precision seeding conveyor belt 7. In this way, the seeds on the precision seeding conveyor belt 7 can directly fall into the seedling tray 8 on the seedling tray conveyor belt 10 below after reaching the tail end of the precision seeding conveyor belt 7. The support columns 11 supporting the precision seeding conveyor belt 7 support the seedling tray conveyor belt 10 in the same way.

[0031] The width of the seeding box 1 is not greater than the width of the precision seeding conveyor belt 7, and the lower part of the seeding box 1 gradually approaches each other from top to bottom along the side walls on the opposite sides in the movement direction of the precision seeding conveyor belt 7, so that the opening at the bottom is narrowed to a width matching the single row of seed holes 6 on the precision seeding conveyor belt 7, so that the lower part of the seeding box 1 presents a shape similar to a funnel.

[0032] Referring to Figure 5In the embodiment, the width of the draw plate 9 is not less than the width of the opening at the bottom of the seed box 1, so that the draw plate 9 can cover the opening at the bottom of the seed box 1 to control the seeding amount. In order to enable the draw plate 9 to be stably positioned at the bottom of the opening, one of the support columns 11 connected to the seed box 1 is provided with a draw plate hole 9 through which the draw plate 9 passes, and the shape of the draw plate hole 9 matches the cross section of the draw plate 9. Since the support column 11 has a certain width, the draw plate 9 can be clamped in the draw plate hole 9 after passing through the draw plate hole 9 and cannot shake. Meanwhile, the upper edge of the draw plate hole 9 matches the position of the opening at the bottom of the seed box 1, so that the seeds cannot fall out of the gap between the opening and the draw plate 9.

[0033] In order to achieve better precision control, the enclosure unit of the embodiment further comprises a baffle plate 3, which is arranged above the upper surface of the precision seeding conveyor belt 7 and has a width matching that of the precision seeding conveyor belt 7. The baffle plate 3 is fixed by the fixed columns 12 fixed to the two sides of the precision seeding conveyor belt 7 and extending upward, and the distance between the bottom end of the baffle plate 3 and the precision seeding conveyor belt 7 is less than the thickness of the seeds in the seed box 1. In this way, the excessive seeds will be stopped by the baffle plate 3 when they are sent to the baffle plate 3 by the precision seeding conveyor belt 7, and can pass through the baffle plate 3 only after falling into the seed holes 6 behind.

[0034] In the embodiment, the lengths of the two enclosure plates 2 of the enclosure unit extend from the opening at the bottom of the seed box 1 to the baffle plate 3, so that the two enclosure plates 2 and the baffle plate 3 together form the guidance and flow control for the seeds.

[0035] Further, in the two enclosure plates 2 of the enclosure unit of the embodiment, one end of at least one of the enclosure plates 2 is provided with an L-shaped hook member 4, and the baffle plate 3 is provided with a sliding groove 5 at a position matching the height of the hook member 4. The hook member 4 is clamped into the sliding groove 5, so that the enclosure plate 2 can move along the sliding groove 5. The hook member 4 has a certain width, so that the baffle plate 3 will not shake when being guided and stopped by the sliding groove 5.

[0036] In the embodiment, the seedling tray conveyor belt 10 and the precision seeding conveyor belt 7 are respectively provided with a driving device, and are driven by the respective driving devices to achieve synchronous or asynchronous movement. In actual use, the specific adjustment can be made according to the needs. When the movement is synchronous, the spacing between the seeds falling into the seedling tray 8 is the same as the spacing between the seed holes 6 on the precision seeding conveyor belt 7. When the movement is asynchronous, the spacing between the seeds falling into the seedling tray 8 is larger or smaller than the spacing between the seed holes 6 on the precision seeding conveyor belt 7.
