。However, as shown in FIG.
The sowing roll 2 is placed between the left and right side walls 4a of the seedling raising box 4 and rotated while being close to the floor 5.
In a seeding device that sows paddy on a bed 5, both ends of the seeding roll 2 are close to the inner surfaces 4b of the left and right side walls of the seedling nursery box 4, so both ends of the seeding roll 2 are wetted by water attached thereto. There was a problem that the rice grains adhered to the seed receiving groove 1, causing unevenness and making it impossible to sow.

前側壁は散水板１９の下端部近傍の裏面に達する。In the above-described configuration, during seeding work, each device is driven, and the seedling box 11 is placed on the conveyor 1.
They are sequentially placed on the end side as shown in 2 and transported in the direction of the arrow a by the conveyor 12, and various operations are performed at the same time.
3, the seedling raising box 11 in which the floor 11a is placed passes through the notch 17a of the irrigation cover 17, and the front side wall of the seedling raising box 11 reaches the back surface near the lower end of the watering plate 19.

を確実に防止できる。Then, when the flow rate adjustment cock 23 is opened and water is supplied from the water supply hose 24 to the water sprinkling pipe 18, water is injected downward from each injection hole 22, and the injected water flows into the buffer body 20 as shown in FIG. After the jetting force is relaxed, the water passes through the buffer 20 and is dripped almost evenly onto the bottom plate 19a of the water sprinkling plate 19, so the falling energy of the water when it falls onto the water sprinkling plate 19 is reduced. Splashing of water on the water sprinkling plate 19 can be reliably prevented.

ない。Further, the water dripping onto the bottom plate part 19a of the water sprinkling plate 19 is sent to the tip part along the groove formed in the shape of a corrugated plate, and is then sent to the top part 111 on the floor.
Since the water is sprayed from the tip close to the floor 113, the falling energy of the water sprayed on the floor 113 is further reduced, and it goes without saying that the water can be prevented from scattering on the floor 11a.

従って潅水時に育苗箱１１の左右側壁１１ ｂ内面に水
