3 and the lower arm 37 are pivotally attached to the free ends of the lower arm 37, the tip of the supporting arm 42 is pivotally attached to either end of the lower arm 37, and the base of the supporting arm 42 is a support plate. As shown in FIG. 7, the up / down link mechanism 46 is mounted on the side of 30 and includes the supporting arm 42. The shaft 38 moves up and down. At this time, the distance between the rotation center shaft 15 and the upper intermediate shaft 35 is determined by the upper arm 33, and the distance between the upper intermediate shaft 35 and the lower intermediate shaft 38 is determined by the intermediate arm 34. Intermediate shaft 38 and output shaft 4
The distance 0 is not changed by the lower arm 37, and the passive gear 32, the upper intermediate gear 36, and the lower intermediate gear 39, which are attached to the rotation center shaft 15, the upper intermediate shaft 35, and the lower intermediate shaft 38, are always meshed with each other. It is arranged so that it moves upward as it is and the supporting arm 42 restricts the rotation of the intermediate arm 34 to prevent the upper intermediate gear 36 from meshing with the output gear 41.

Therefore, the rotation center shaft 15 of the strip roller 10 is constantly urged by the spring 44 so as to descend.
This is the gist of the present invention. That is, the mounting plate 16 is urged so as to descend by the traction spring 29, but when the mounting plate 16 is pulled by one traction spring 29, the elasticity of the traction spring 29 is centered on the rotation center shaft 15. This is also prevented because it also acts on rotating 16. In this embodiment, the spring 44 is wound around the mounting shaft 43, one end of the spring 44 is brought into contact with the supporting arm 42, and the up-and-down corresponding rotation transmission mechanism X is interposed via the supporting arm 42.

In FIG. 4, the retreat groove 50 is formed on the front side of the guide groove 48, but if it is formed on the rear side of the guide groove 48, the traction spring 29 causes the retraction roller 29 to move up to the uppermost position of the guide groove 48. The guide projection 49 may be engaged with the retracting groove 50 by the action of rotating the mounting plate 16, and in order to prevent this, in the positional relationship between the rotation center shaft 15 and the traction spring 29, the strip roller 10 and the like are the largest. The retracting groove 50 is formed so that the guide protrusion 49 engages when it is tilted against the elastic force of the traction spring 29 at the upper position.

Therefore, as shown in FIG. 16, the traction spring 2
The withdrawal groove 50 may be formed in the guide groove 48 on the opposite side to the guide groove 48. However, when the guide groove 48 is formed between the rotation center shaft 15 and the traction spring 29 as shown in FIG. Can be narrowed, and the entire mounting device can be downsized.

Reference numeral 61 is a seed pad guide device which guides the seed pad fitted in the horizontal groove 57 provided on a part of the outer peripheral surface of the horizontal shaft feeding roll 56 from an upper position to a lower position. Thus, when the seed supplying device 6 is used for row seeding by moving the whole seed supplying device 6 upward with respect to the transfer table 1 and locating it in the upper position,
When the whole seed supply device 6 is lowered to be positioned below and used for dissemination, the seed supply device 6 is mounted above the transfer table 1 by a vertical position switching device 62 having an arbitrary structure so as to be switchable. Reference numeral 63 is a paddy guide having split falling openings in the left and right directions,

[0014]

Next, the operation will be described. The rotating brush 8, the ridged roller 10 and the compression roller 12 are
Are respectively mounted on the left and right mounting plates 16 connected by the connecting body 19, the rotation center shaft 15 is vertically mounted on the long hole 31 of the support plate 30, and the traction spring 29 is mounted on the mounting plate 16. Since the height adjusting rod 24 is screwed to the mounting plate 16, when the height adjusting rod 24 is rotated, the lower end of the height adjusting rod 24 comes into contact with the upper surface of the transfer table 1 to adjust the height. The mounting plate 16 moves up and down with respect to the rod 24, and the height position is adjusted to the standby height corresponding to the seedling raising box 2 by the action of each of the rotating brush 8, the row roller 10 and the pressure suppressing roller 12, and is held. Further, when the pressing force adjusting screw 28 is rotated, the pressing force adjusting screw 28 moves up and down with respect to the mounting plate 16, so that the force of pulling the pulling spring 29 downward is adjusted. In this case, the traction spring 29 also acts to rotate the mounting plate 16 about the rotation center shaft 15, but by providing the height adjusting rod 24 between the traction spring 29 and the rotation center shaft 15, the standby height can be increased. And the rotation action of the mounting plate 16 is also regulated.

When the seedling raising box 2 is supplied to the starting end of the transfer table 1 in the above-mentioned state, it is transferred by the transfer roll 4 and supplied with the bed soil by the bed soil supply device 5, and the supplied bed soil is a rotary brush. 8 is leveled and a leveled groove 10 is formed on the upper surface of the leveled soil by a roller 10 for striping in the front-back direction parallel to the transfer direction of the nursery box 2, and the horizontal axis feeding roll 56
The seed paddy that fits into the horizontal strip groove 57 and co-rotates with the horizontal axis feeding roll 56 falls into the strip groove 11 in the state of being divided by the split drop openings of the guides 63, and is seeded. The pressure is suppressed by the pressure roller 12 so as to collapse the mountain portions that form the groove together, then the water is supplied by the water supply device 22, the soil cover is supplied by the soil cover supply device 7, and the rotary brush 8 on the front side of the soil cover supply device 7 is received. By this, the soil cover dropped on the side wall of the seedling raising box 2 is swept and the seeding work is completed. In this case, since the strip roller 10 and the compression roller 12 all work over the front wall of the seedling raising box 2 and act over the rear wall to act on the succeeding seedling raising box, they move up and down. Explaining with an example of the roller 10, the roller 1 with a strip
The rotation center shaft 15 of 0 is mounted on the mounting plate 16 so that the mounting plate 1
Reference numeral 6 stands by at a predetermined height below the upper surface of the front wall of the seedling raising box 2 by means of a height adjusting rod 24.
Is vertically movable in the long hole 31 of the support plate 30 and is completely free to move up. Therefore, when the front wall of the seedling raising box 2 comes into contact with the row roller 10, it is pushed up by the front wall. Then
Then, the linear roller 10 and the left and right mounting plates 16 are integrally moved upward. When the front wall of the nursery box 2 passes below, the attachment plate 16 descends due to the action of the traction spring 29, and the row roller 1
0 descends to form a groove 11 in the bed soil in the nursery box 2.

In this case, the mounting plate 16 is attached to one traction spring 2
When pulled by 9, the elastic force of the traction spring 29 also acts to rotate the mounting plate 16 about the rotation center axis 15, but the rotation center axis 15 of the strip roller 10 or the like of the present invention is
Since the spring 44 constantly urges it to descend,
Together with the traction spring 29, the front and rear sides of the mounting plate 16 are urged so as to descend to ensure smooth lowering of the strip roller 10 and the like. Since the support plate 30 provided with the up / down corresponding rotation transmission mechanism X is provided with the mounting shaft 43, the spring 44 is wound around the mounting shaft 43, and one end of the spring 44 is brought into contact with the supporting arm 42. The supporting arm 42 always rotates downward to pull the upper arm 33, and the upper arm 33 lowers the rotation center shaft 15 to smoothly and reliably lower the strip roller 10 and the like. Further, a mounting shaft 45 is provided on the support plate 30 not provided with the up / down corresponding rotation transmission mechanism X, the base of the rotating arm 47 is pivotally attached to the mounting shaft 45, and the tip of the rotating arm 47 is attached to the rotation center shaft 15. Since the spring 44 is wound around the mounting shaft 45 and urges the rotating arm 47 to rotate downward, the rotating arm 47 rotates downward to rotate the rotation center shaft 15.
Is lowered.

Therefore, the spring 44 is used as the strip roller 10.
Since the spring 44 and the rotation center shaft 15 are not directly engaged with each other, the durability of the mounting portion of the spring 44 is ensured with a simple structure. Then, on the rear side of the support plate 30, a vertically elongated guide groove 48 parallel to the elongated hole 31 is formed.
Since the guide projection 49 provided on the mounting plate 16 is engaged with the guide groove 48, the mounting plate 16 moves up and down the rotation center shaft 15 that moves up and down the slot 31 and the guide groove 48. The guide projections 49 vertically move up and down, and as a result, the strip roller 10 and the like vertically move up and down. Next, the guide groove 4
Since the withdrawal groove 50 is formed in the upper part of 8, the guide protrusion 49 engages with the withdrawal groove 50 when the mounting plate 16 is rotated about the rotation center shaft 15 at the uppermost position of the strip roller 10 and the like. In combination, the row roller 10 and the like are held at the standby position above the upper surface of the nursery box 2. In this case, the relationship between the guide groove 48 and the retracting groove 50 is such that the retracting groove 50 is engaged so that the guide projection 49 engages when the strip roller 10 or the like is tilted at the uppermost position against the elasticity of the traction spring 29. Since it is formed, the guide projection 49 engages with the retracting groove 50 against the elasticity of the traction spring 29, and the striated roller 10 or the like is at the uppermost position in the working state, and the elasticity of the traction spring 29 is reached. As a result, the mounting plate 16 is rotated around the rotation center shaft 15 and the guide protrusion 49 is moved to the retract groove 5.
0 to prevent engagement with the roller 10 in the working state.
Even if they are at the uppermost position, they are surely lowered (FIGS. 4 and 16).

Further, at this time, as shown in FIG. 16, the retract groove 50 may be formed in the guide groove 48 on the side opposite to the traction spring 29. However, as shown in FIG.
By disposing between 5 and the traction spring 29, the front-back width of the support plate 30 can be narrowed, and the mounting device as a whole can be downsized. Then, the rotation center shaft 15 and the output shaft 4 of the strip roller 10 and the like.
Since the up-and-down corresponding rotation transmission mechanism X is provided between the rotation center shaft 15 and 0, when the rotation center shaft 15 moves upward along with the strip roller 10 and the like, the rotation center shaft 15 pulls the upper arm 33 upward, 7, the lower part of the upper arm 33 pulls the upper intermediate shaft 35 upward, and the upper intermediate shaft 35 pulls the upper part of the intermediate arm 34. , The lower part of the intermediate arm 34 pulls the lower intermediate shaft 38, and the lower intermediate shaft 38 is attached to the lower arm 3.
7, the upper part of 7 is pulled upward, and the lower arm 37 moves the output shaft 40
As a result, the rotation center shaft 15, the upper intermediate shaft 35, and the lower intermediate shaft 38 move upward from the initial position, but the distance between the rotation center shaft 15 and the upper intermediate shaft 35 increases. The arm 33 does not change the distance between the upper intermediate shaft 35 and the lower intermediate shaft 38 by the intermediate arm 34, and the distance between the lower intermediate shaft 38 and the output shaft 40 by the lower arm 37. The passive gear 32 attached to the upper intermediate shaft 35, the lower intermediate shaft 38, the upper intermediate gear 36, and the lower intermediate gear 39 move upward while always meshing with each other.

Therefore, the row roller 10 and the like rotate even when pushed up by the front wall of the seedling raising box 2, and the height adjusting rod 24 is used by the height adjusting rod 24 to use the seedling raising box 2 having different heights. Even if the height of is raised, it is driven and rotated. Further, in the embodiment of FIG. 17, when the rotation center shaft 15 moves upward, the chain 70 extends against the elastic force of the spring 73 to rotate the tension arm 72, and conversely, the rotation center shaft 15
Is moved downward, the tension arm 72 is rotated by the elastic force of the spring 73 to remove the looseness of the chain 70, and in any case, the rotation of the output gear 41 is transmitted to the passive gear 32. Further, the up / down corresponding rotation transmission mechanism X of this embodiment is also compact because the front / rear width is sufficient to secure the rotation amount of the tension arm 72. Then, the seed supply device 6
The paddy guide 63 below the feeding roll 56 is removed together with the parallel link 64, and the whole seed feeding device 6 is lowered by the vertical position switching device 62 to the dispersal position, and the strip roller 10 and the pressure roller 12 are moved upward. Then, the guide protrusion 49 of the mounting plate 16 is engaged with the retreat groove 50 formed in the upper portion of the guide groove 48 of the support plate 30 to retreat, and in this state, when the seedling raising box 2 is supplied to the starting end portion of the transfer table 1, The bed soil is supplied by the bed soil supply device 5, the supplied bed soil is leveled by the rotating brush 8, and fitted into the horizontal groove 57 of the horizontal shaft feeding roll 56 on the leveled floor soil. Horizontal axis feeding roll 56
The seeds that have been co-rotated with are dropped and sprinkled as they are, and then irrigated by the irrigation device 22, the soil is supplied by the soil cover supply device 7, and the rotary brush 8 on the front side of the soil cover supply device 7 is placed on the side wall of the nursery box 2. The covering soil that fell into the area is swept and the seeding work is completed.
