A seeding guide plate with a large number of openings for dropping seeds is placed on the seedling nursery box, and while the seedling guide plate is being transported, a fixed amount of seeds are dropped by a feed roll that is rotationally driven from above. It is configured to sow a substantially constant number of seeds at each interval.

(Problems to be Solved by the Invention) In the prior art, the seedling growing boxes are transported by a transport mechanism such as a belt conveyor, and the delivery rolls are configured to receive rotational force from the transport mechanism or from a dedicated drive source. ,
Therefore, a power transmission means for the feeding roll is required, and even if the pitch of the opening of the sowing guide plate and the pitch of the seed receiving part of the feeding roll are the same, the position of the seedling box on the transfer mechanism is uncertain. Therefore, the opening and the seed receiver may be out of phase and do not face each other, causing a slight change in the number of seeds that enter the opening, resulting in uneven seedlings or clustered seedlings.

(Means for Solving the Problems) In view of the conventional problems as described above, the present invention provides a rack on one side edge of a seeding guide plate placed on a seedling nursery box that can move linearly relative to the seeding mechanism. The feeding roll is equipped with a pinion that can engage with the rack, and the feeding roller μ is rotated by the relative movement of the seedling box, and the feeding roll is always fed at the optimal timing in accordance with the opening for dropping seeds on the sowing guide plate. An object of the present invention is to provide a seedling-raising seeding machine capable of dropping seeds from a roll.

A feature of the present invention for achieving this purpose is that a seed guide plate having a large number of openings for dropping seeds is placed on the nursery box, and a rotatable feeding roll and a rotatable feeding roll are placed above the nursery box. In a seedling-raising seeding machine, which is equipped with a seeding mechanism having an upper hopper and drops seeds onto a seeding guide plate while moving the seedling-growing box and the seeding mechanism in a relative straight line, half 11 pairs of ii. 11. A rank is formed on one side edge parallel to the moving direction, and a pinion that anastomoses with the hook is provided at one end of the feed roll.

(Function) When the sowing guide plate (4) having a large number of openings (to) is placed and fitted in the seedling raising box (2) and moved relatively below the feeding row/L' (6), the sowing guide plate ( The rack ■υ of 4) meshes with the pinion of the feed-out row 1v (6), and the seedling box (

A large number of groove-shaped seed receivers OD are formed on the outer circumferential surface of the feed roll (6), which are parallel to the axial direction, and receive the seeds OcJ supplied from the hopper (9), rotate approximately 180 degrees, and send the seeds to the lower side. When this happens, the seedlings fall into the nursery box (2). The falling guide plate (2) is an arcuate plate along the feeding roller lL/(61), and is pressed by the spring (13) toward the feeding roller 1v (6) side, so that the seeds OCJ in the seed receiving part 0 are on the lower side. Regulations are in place to prevent people from accidentally falling on the way to their destinations.

The rotating brush (8) is supported by a machine frame (5),
The position can be freely adjusted in the radial direction with respect to the feed roll (6), and by adjusting the amount of overlap with the feed roll (6), the amount of seeds in one seed amount section 01) can be adjusted. This rotating brush (8) is rotationally driven in the direction of the arrow by the feed roll shaft (7) via gears α4α9 and intermediate gear QQ.

A pinion rod is provided at one end of the feed-out row/v (6), and can be engaged with a rack e2D provided on the negative side edge of the seeding guide plate (4).

Moreover, both shaft ends of this feed-out row tv (6) serve as rolling parts that roll on the left and right sides of the seeding guide plate (4). This rolling part (a) has a larger diameter than the central part in order to form a gap between the central part of the feed roll (6) and the upper surface of the seeding guide plate (4). However, the transfer part may have the same diameter as the central part, and the upper surface of the seeding guide plate (4) may be made concave. In addition, wheels are provided on the left and right sides of the machine frame (5) without forming the rolling part (a), and the sowing mechanism (
3) may be made movable with respect to the ground.

The sowing guide plate (4) has a stepped portion (C) around the lower surface, is fitted onto the peripheral wall of the seedling nursery box (2), and is immovable in relative position, and has a large number of parallel groove-shaped openings. It has a part (c). A rack Q1) is formed on the upper surface of one side edge parallel to the relative movement direction (A) of this seeding guide plate (4).

As shown in Fig. 1, the machine frame (5) has a feeding row/l.
/(6), supports a rotating brush (8) and a hopper (9), and can be carried and pushed by hand with a fixed handle (c).

Therefore, the m types of operations of the seeding machine (1) of the first embodiment are as follows:
Place the seedling raising box (2) containing bed soil (sha) on the ground, place the sowing guide plate (4) on top of it, bring the sowing mechanism (3) onto one end of it, and rack the pinion. While meshing with 0υ, feed out the low/l/ (6) onto the sowing guide plate (
4) Touch 1-1 on the top and hold the hand /L/(to) in that state and sow #l! When the structure (3) is pushed in the direction of the arrow (B), the seedling raising box (2) is relatively moved linearly in the direction of the arrow (A). Due to the rotation of the pinion, the feed-out low) v (6
) rotates, and the seed receiving part Qll accurately corresponds to the opening (), drops the seeds OG, supplies them onto the floor, and after sowing to the tip of the seedling box (2), Lift up the seeding mechanism (3) and carry it to another seedling nursery box.
