[Operation] Next, the operation will be described. Since the present invention has the above configuration, when the seedling raising box 2 is supplied to the transfer table 1, the seedling raising box 2 is transferred in the direction a, and the bed soil is supplied by the bed soil supply device located above during the transfer. This method of supplying the bed soil is such that the excess soil is removed by removing the excess material, so the upper surface of the bed soil is leveled with a rotating leveling brush, and the corners of the rear wall 4 and the front wall 5 of the seedling raising box 2 are fed. Excessive soil accumulated in the portion is pressed by the corner pressing device 6. The transfer rate of the seedling raising box 2 is arbitrarily set to about 200 to 1500 boxes per hour.

The corner pressing device 6 comprises a rear wall corner pressing device 7 for pressing the corner of the rear wall 4 and a front wall corner pressing device 8 for pressing the corner of the front wall 5, and the rear wall corner The turning frame 11 of the section pressing device 7 is restricted from rotating upward by the height adjuster 30, so the standby height of the rear wall corner pressing body 19 corresponds to the upper surface of the floor soil by the height adjuster 30. Then, the height is adjusted so that it does not come into contact with the top surface of the soil in the seedling raising box 2 but collides with the rear wall 4 of the seedling raising box 2, and the downward rotation of the rotating frame 11 rotating frame 11 adjusts the depth. Since it is regulated by the bolt 28, the depth adjusting bolt 2
8, the pressing depth of the rear wall corner pressing member 19 is adjusted. In this state, the seedling raising box 2 is supplied to the transfer table 1 to supply the floor soil, and the top surface of the floor soil is leveled with the rotating leveling brush, or the floor soil is supplied and When the seedling-raising box 2 having a flat upper surface is supplied to the transfer table 1, the front wall 5 of the seedling-raising box 2 is
Comes into contact with the rear surface of the rear wall corner pressing body 19 and advances the rear wall corner pressing body 19 by moving the front wall 5 of the seedling raising box 2, and the rear wall corner pressing body 19 attaches the rotating frame body 11. When the front connecting portion 14 comes into contact with the depth adjusting bolt 28 by the downward rotation of the rotating frame body 11 about the shaft 12, the downward rotation of the rotating frame body 11 is stopped, but the rear wall is stopped. The corner pressing member 19 is further advanced by the moving nursery box 2, and the rear wall corner pressing member 19 is the rotating member 1.
When the lower part of the rear wall corner pressing body 19 is rotated up to the upper end of the front wall 5, the front wall 5 is rotated.
Passes below the rear wall corner pressing body 19, and the rear wall corner pressing body 19 rotates together with the rotating member 18 around the lower mounting shaft 17 by the elastic force of the spring 23, and the rotating frame body 11 also rotates the spring 29. The elastic member is rotated upward, and the rear plate 26 of the rotating member 18 is rotated by the shaft member 2
5, the rotation is stopped by abutting on the front end of 5, the rotation frame body 11 is contacted by the front end of the height adjuster 30 and the rotation is stopped, and the rear wall corner pressing body 19 passes over the front wall 5. Stand by at the set height above the floor soil.

Next, when the front wall 5 of the seedling raising box 2 passes under the rear wall corner pressing device 7 and the seedling raising box 2 further advances, 19 actually presses the corner soil of the rear wall 4. Before this, the front wall 5 of the nursery box 2 reaches below the front wall corner pressing body 41 of the front wall corner pressing device 8, but the rear wall corner pressing device 7 will be described first for the sake of explanation. The rear wall corner pressing body 19 which has passed over the front wall 5 and stands by at the set height of the top surface of the floor soil abuts on the front surface (inner surface) of the rear wall 4, and as a result, as described above, the rotating frame body 11 Is rotated downward, and the rear wall corner pressing body 19 is lowered with respect to the floor soil by the downward rotation of the rotating frame body 11, and the front connecting portion 14 is rotated by the downward rotation of the rotating frame body 11. Contacting the depth adjusting bolt 28, the downward rotation of the rotating frame body 11 is stopped, and the corner soil of the rear wall 4 is pressed to the maximum to be flat,
Next, the rear wall 4 is overcome by the same action as the front wall 5 is overcome.

However, the downward movement of the front wall corner pressing member 41 is restricted by the height adjusting device 47, and the standby height and the pressing depth are the same, so the pressing member 42 is pressed by the height adjusting device 47.
Adjust the standby height of the so that it corresponds to the top surface of the soil floor. When the front wall 5 of the seedling raising box 2 reaches below the front wall corner pressing member 41 of the front wall corner pressing device 8, the front wall 5 of the seedling raising box 2 is inclined guide surface 43 of the front wall corner pressing member 41. The front wall corner pressing body 41 tries to push up the front wall corner pressing body 41 by the movement of the seedling raising box 2, and the front wall corner pressing body 41 tries to rotate the front-rear moving mounting body 37 upward about the pivot 38. Since the guide hole 45 of the movement guide portion 44 of the front-rear moving mount 37 is engaged with the restriction protrusion 46, the force by which the front wall corner pressing body 41 pushes up the front end of the front-rear moving mount 37 is Acting on the rearward movement of 37, the front-back movement mounting body 37 rotates the arm 35 to the rear side, and the front wall corner pressing body 41 moves backward while moving upward (FIG. 5).

Next, the front wall 5 of the seedling raising box 2 passes below the pressing portion 42 and the front wall 5 of the seedling raising box 2 advances, but when the front wall corner pressing member 41 starts to descend, Contrary to the above, the front-rear movement mounting body 37 advances the arm 35 by rotating the arm 35 to the front side, and the front wall corner pressing body 41 advances while descending, and follows the advancing front wall 5 to move the front wall. Corner pressing body 41
The pressing portion 42 of the front wall 5 descends while sliding on the rear surface (inner surface) of the front wall 5 (FIG. 8), and when the front wall 5 presses the corner soil to the maximum to flatten it, the bolts of the height adjusting device 47. The lower end of 49 abuts on the upper surface of the transfer table 1 and stops the lowering of the front wall corner pressing body 41.

In this case, the arm 35, the shaft 36, and the shaft mount 38
In this relation, since the shaft attachment 38 rotates about the shaft 36 located below, the shaft 38 moves forward when rotated downward as shown in FIG. 6, but the front wall corner pressing member 41 serves as the rotation center. Since it is located below 36, if it is simply rotated downward by the arm 35, it will move up and down or move backward at that position, and the soil at the corner of the front wall 5 of the nursery box 2 cannot be pressed. Become. In the present invention, the front-rear moving attachment body 37 is rotatably attached to the axle attachment 38, and the guide hole 45 of the movement guide portion 44 of the front-rear moving attachment body 37 is engaged with the immovable restriction projection 46. Therefore, the forward-backward movement mounting body 37 is guided by the regulation projection 46, and the forward rotation is regulated like a parallel link.

Therefore, the front wall corner pressing device 8 can be constituted by the pressing part 42 which is provided on the side plate 10 separate from the transfer table 1 and which moves about the shaft 36 which is a high rotation center. The wall corner pressing device 7 and the front wall corner pressing device 8 can be integrally attached to the frame, and the assembling / assembling is facilitated. Further, since the front-rear moving mounting body 37 and the front wall corner pressing body 41 are mounted on the arm 35 with the shaft 36 of the center of rotation being down, it may be provided below the rear wall corner pressing device 11. This makes it possible to effectively use the space and reduce the overall size.

Further, the spring 50 is connected to the arm 35 and the frame 9
Since it is provided between and, even if it is flipped up by the front wall 5 of the nursery box 2 that moves at high speed, it immediately descends, so that the soil can be reliably pressed. Further, since the front wall corner pressing device 8 presses the corner soil regardless of the pressure roller, it is possible to select whether or not to perform the pressure reduction work, and improve the versatility of the work content. In addition, in order to facilitate understanding,
Although it has been explained with the movement of one seedling raising box 2, in the actual work, since the seedling raising box 2 is continuously transferred without a gap, the rear wall 4 of the preceding seedling raising box 2 has a rear seedling raising box 2 The front wall 5 moves in contact, so that the rear wall corner pressing device 7 and the front wall corner pressing device 8 simultaneously ride over the rear wall 4 and the front wall 5, especially the front wall corner pressing device 8. The front wall corner pressing body 41 abuts on the inner surface of the rear wall 4 and moves upward, climbing over the rear wall 4 and the front wall 5,
It works when the front wall 5 passes.
