As shown in fig. 2, the sowing portion 5 has: a hopper 10 for storing seeds; a delivery drum 11; a guide member 12; a cleaning brush 13; a scraping brush 14; a flow-down guide plate 15 for guiding the seeds to flow down toward the feed roller 11; a motor 16 for rotationally driving the feed roller 11; a housing 17 in which a feed roller 11 and the like are built; and a seed leakage preventing part 22 for preventing the leakage of the seeds. The inside of the casing 17 is provided with a guide member 12, a cleaning brush 13, a scraping brush 14, a flow-down guide plate 15, a motor 16, a seed leakage preventing unit 22, and the like, in addition to the feed roller 11. A hopper 10 is mounted on the upper portion of the box 17.
A plurality of groove-shaped recesses 11a, which are long in the left-right direction and serve as recesses into which seeds are introduced, are formed on the outer circumferential surface of the feed roller 11. The feed roller 11 rotates about the rotation axis X1 (the rotation direction a shown in fig. 2), and feeds out the seeds in the concave portion 11 a. The rotation axis X1 extends in a lateral direction (left-right direction) perpendicular to the conveying direction of the conveying device 2 in plan view.
The cleaning brush 13 is rotated about a rotation axis X2 parallel to the rotation axis X1 of the feed roller 11, thereby cleaning the recess 11 a. The seeds remaining in the concave portion 11a are raked out by the cleaning brush 13. The cleaning brush 13 is disposed on the upstream side of the feed roller 11 in the conveying direction of the conveying device 2.
The scraping brush 14 is rotated around a rotation axis X3 parallel to the rotation axis X1 of the feed roller 11, thereby scraping off the excess seeds in the concave portion 11 a. The squeegee brush 14 is disposed above the feed roller 11.
Of the two flow-down guide plates 15, a flow-down guide plate (hereinafter referred to as an "upstream flow-down guide plate") 15 located on the upstream side in the conveying direction of the conveying device 2 is provided in a state of being inclined downward toward the downstream side in the conveying direction of the conveying device 2. The upstream-side flow-down guide plate 15 is provided so as to straddle the left and right side plates of the casing 17.
Of the two flow-down guide plates 15, a flow-down guide plate (hereinafter referred to as a "downstream flow-down guide plate") 15 located on the downstream side in the conveying direction of the conveying device 2 is provided in a state of being inclined downward toward the upstream side in the conveying direction of the conveying device 2. The downstream-side flow-down guide plate 15 is provided so as to straddle the left and right side plates of the casing 17.

The seed leakage preventing part 22 has a pair of left and right first seed leakage preventing plates 23, second seed leakage preventing plates 24, and seed leakage preventing portions 15 a. The first seed leakage prevention plate 23 on the left side is provided at a portion corresponding to the left end portion of the feed roller 11 and the left end portion of the leveling brush 14. The first seed leakage prevention plate 23 on the left side prevents the seeds from leaking from a portion corresponding to the left end portion of the feed roller 11 and the left end portion of the scraping brush 14 (specifically, between the left end portion of the feed roller 11 and the left end portion of the scraping brush 14, and the left side plate of the case 17).
The first seed leakage prevention plate 23 on the right side is provided at a position corresponding to the right end portion of the feed roller 11 and the right end portion of the scraping brush 14. The first seed leakage prevention plate 23 on the right side prevents the seeds from leaking from a portion corresponding to the right end portion of the feed roller 11 and the right end portion of the scraping brush 14 (specifically, between the right end portion of the feed roller 11 and the right end portion of the scraping brush 14, and the right side plate of the case 17).
The edge 23a of the first sub-leakage prevention plate 23 on the delivery drum 11 side is formed in a circular arc shape along the outer circumferential surface of the delivery drum 11. A portion of the first sub-leakage prevention plate 23 located on the downstream side in the conveying direction of the conveying device 2 protrudes toward the scraper brush 14 so as to overlap with the scraper brush 14 when viewed from the side. This ensures that the seeds enter the concave portion 11a of the feed roller 11, and prevents the seeds from leaking.
The second seed leakage prevention plate 24 is provided on the downstream side in the conveying direction of the conveying device 2 with respect to the scraping brush 14. The second seed leakage prevention plate 24 is provided in such a manner as to straddle the left and right side plates of the case 17. The second seed leakage prevention plate 24 prevents the seeds from leaking from a portion located on the downstream side in the conveying direction of the conveying device 2 with respect to the scraping brush 14 (specifically, between the housing portion 17a of the housing 17 that houses the motor 16 and the upper end portion of the receiving member 21).
A seed leakage prevention portion 15a is formed at the end of the upstream-side downflow guide plate 15 on the delivery drum 11 side. The seed leakage prevention part 15a prevents the seeds from leaking from between the feed-out drum 11 side end of the upstream-side flow-down guide plate 15 and the feed-out drum 11. The seed leakage prevention part 15a is formed in a shape in which the end of the upstream-side downward guide plate 15 on the feed roller 11 side is bent downward along the outer circumferential surface of the feed roller 11.
