For example, Japanese Patent Application Laid-Open No. 61-149027. In these techniques, a flat soil leveling plate is pulled by a spring, and when the flat plate collides with the end of the seedling box, the soil on the slope is scooped up and discharged, thereby leveling the soil.

(c) Problems that the invention aims to solve With this configuration, the raised part a on the rear side is scooped up and leveled as shown in Figure 4, but the starting edge of the next seedling box is The raised portion b on the side could not be leveled. Therefore, even if the seeds were sown, they would roll around in the raised area b on the starting end side, creating areas with more and less seedlings, and areas with more and less soil to cover the seeds. It is.

In addition, when filling the seedling box with soil,
In order to increase efficiency, work was carried out continuously by connecting the rear end of a seedling box to the front end of the next seedling box, so it was a huge time loss to level the edges of each box one by one. .

The seeding device 6 has a hopper 6a arranged at the top,
A feeding belt is arranged below it. The seeding belt has recesses formed at appropriate intervals on its surface into which the seeds fit, and the seeding belt is driven by the conveyor roller 3 via a chain 14. Reference numeral 17 is a brush for removing seeds on the edge of the seedling nursery box 9 after sowing.

The soil-filling device 7 puts soil into a hopper and drops it a certain amount at a time by driving the motor 13, so that the seeds in the seedling box 9 passing through are covered with soil. The power from the motor 13 drives the soil digging device 7, and also passes through the chain 15 to the conveyor rollers 3,
Power is transmitted to the chain 16 that drives 3.... Reference numeral 19 denotes a brush for removing soil on the edge 9a of the seedling box 9 after soil has been added.

The leveling device 4, which is the essential part of the present invention, is used to level the inner edge of the seedling box 9 after filling the seedling box 9 with soil and leveling it with rollers. Alternatively, it is used to level the soil covered after sowing, and its configuration is explained with reference to FIGS. 2 and 3. A substantially L-shaped frame 20 is placed on the front and rear conveyor frames 2,
are fixed with bolts 21, 21. A support frame 22 has a pin 23 at the upper end of the frame 20.
It is supported by

A shaft 24 is horizontally installed at the other end of the support frame 22, and an arm 25 and a corner leveler 26 are pivotally supported. Further, the tip 22a of the support frame 22 is bent inward, and a bolt 27 for adjusting the height of the corner flat body 26 is threaded thereon so that it can be fixed with a lock nut 29. It touches the top side.

The tip 25a of the arm 25 contacts the frame 20 to prevent it from falling when there is no seedling box bent outward.

Further, a shaft 30 is pivotally supported at the tip end, and the shaft 30
At both ends are rollers 31 made of rubber or the like that roll on both side edges 9a of the seedling box 9, and at the center of the shaft 30 are rollers 31 having a diameter larger than the rollers 31 for lifting the corner flat body 26 when getting over the edges. A large diameter roller 32 is inserted.

The tops of side plates 26a at both front and rear ends of the corner flattened body 26 are pivotally supported by the shaft 24, and pins 33 are provided to protrude outward from the lower portions of the side faces to limit the rotation range of the corner flattened body 26 to the support frame 22. It is regulated within the arm 25.
