[0012]

[Operation] Next, the operation will be described. The rotating brush 8, the ridged roller 10 and the compression roller 12 are
Since the left and right mounting plates 16 are respectively mounted on the mounting plate 16, when the height adjusting rod 24 is rotated, the height adjusting rod 24 is attached to the mounting plate 1.
6, the height position of the row roller 10 or the like is adjusted corresponding to the seedling raising box 2, and the lower end of the height adjusting rod 24 of the row roller 10 or the like contacts the upper surface of the transfer table 1. Holds at the waiting height. 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 the pulling spring 29 for pulling the strip roller 10 and the like downward is adjusted. In this case, the rotary brush 8, the liner roller 10 and the compression roller 12 are mounted on the left and right mounting plates 16 with the rotation center shaft 15 by an arbitrary bearing member so as not to move in the left and right directions.
Further, since the left and right mounting plates 16 are connected by the mounting frame 19 for mounting the soil removing brush 21 and the like, the strip roller 10, the left and right mounting plates 16 and the mounting frame 19 are fixed to each other to form a frame structure, These are raised and lowered integrally. Therefore, the height can be adjusted accurately by the left and right height adjusting rods 24, and as will be described below, the left and right corresponding to the movement of the seedling raising box 2 move up and down evenly to operate accurately. .

When the seedling raising box 2 is supplied to the starting end of the transfer table 1 in the above 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 supplied. Is leveled by the rotating brush 8, and the leveled soil is leveled by the row roller 10 in the front-rear direction.
, The seed paddy that is fitted into the horizontal strip groove 57 of the horizontal axis feeding roll 56 and co-rotated by the horizontal axis feeding roll 56 is dropped in the row groove 11 in a state of being divided by the split drop ports of the guide 63. And the soil in the nursery box 2 is squeezed by the squeezing roller 12, and then irrigation is performed by the irrigation device 22, 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 used. The soil covering dropped on the side wall of the nursery box 2 is swept and the seeding work is completed. Then, the rotating brush 8, the compression roller 12, the roller with a strip 1
The vertical action of 0 will be explained using the example of the strip roller 10,
Since the central axis 15 of rotation of the barbed roller 10 is only vertically movably mounted in the long hole 31 of the support plate 30, the height adjustment rod 24 allows the predetermined height below the front wall of the nursery box 2. You can move up just by waiting at
When the front wall of the nursery box 2 comes into contact with the strip roller 10, it is pushed up by the front wall and moves upward, and then the strip roller 1
When the mounting plate 16 and the mounting frame 19 and the soil removing brush 21 on both the left and right sides of 0 move up integrally, and the rotation center shaft 15 moves up along with the strip roller 10, the rotation center shaft 15 moves to the upper arm 33. While the upper arm 33 rotates counterclockwise in FIG. 5 about the rotation center shaft 15, the lower part of the upper arm 33 pulls the upper intermediate shaft 35 upward, and the upper intermediate shaft 35 is the intermediate arm. Tow the top of 34,
The lower part of the intermediate arm 34 pulls the lower intermediate shaft 38, the lower intermediate shaft 38 pulls the upper part of the lower arm 37 upward, and the lower arm 37 pivots upward about the output shaft 40, resulting in , The rotation center shaft 15, the upper intermediate shaft 35, and the lower intermediate shaft 38
Moves above the initial position, but the distance between the rotation center shaft 15 and the upper intermediate shaft 35 is lowered by the upper arm 33, and the distance between the upper intermediate shaft 35 and the lower intermediate shaft 38 is lowered by the intermediate arm 34. Since the distance between the side intermediate shaft 38 and the output shaft 40 is not changed by the lower arm 37, the passive gears 3 attached to the rotation center shaft 15, the upper intermediate shaft 35, and the lower intermediate shaft 38 are disposed.
2, the upper intermediate gear 36, and the lower intermediate gear 39 move upward while always meshing.

Therefore, the strip roller 10 is used as the nursery box 2
It rotates even if it is pushed up by the front wall of No. 2, and it is driven and rotated even if the height of the strip roller 10 is raised by the height adjusting rod 24 in order to use the nursery boxes 2 having different heights.
Then, the rotation center shaft 15 of the strip roller 10 is only rotatably mounted in the elongated hole 31 of the support plate 30 and the downward movement is completely free within the range of the elongated hole 31, When the front wall of the nursery box 2 passes below the row roller 10,
The attachment plate 16 and the attachment frame 19 and the soil removing brush 21 on both the left and right sides of the roller 10 are attached by their own weight and the traction spring 29.
When the rotation center shaft 15 moves downward along with the strip roller 10, the rotation center shaft 15 pushes the upper arm 33 downward, and the upper arm 33 moves to the rotation center shaft 15 center. 5, the lower part of the upper arm 33 pushes the upper part of the intermediate arm 34 downward, the lower part of the intermediate arm 34 pushes the upper part of the lower arm 37 downward, and the lower arm 37 turns the output shaft. As the result, the barbed roller 10 rotates downward about the center of 40, and as a result, the strip roller 10 descends to the standby position held by the height adjusting rod 24, and becomes the initial state. Therefore, the rotation center shaft 15, the upper intermediate shaft 35, and the lower side. The passive gear 32, the upper intermediate gear 36, and the lower intermediate gear 39 mounted on the intermediate shaft 38 move downward while always meshing with each other.

In this case, the upper intermediate shaft 35 provided on the upper portion of the intermediate arm 34 has the base portion pivotally mounted on the mounting shaft 43 of the mounting plate 16 and the lower portion of the supporting arm 42 pivotally mounted thereon. 35 only pivots about the mounting shaft 43, and therefore the lower intermediate shaft 38 via the intermediate arm 34.
Is prevented from rotating below a predetermined position at all times to prevent the upper intermediate gear 36 from meshing with the output gear 41.
As described above, the row roller 10 rotates even when it goes over the front wall of the nursery box 2, and the height of the row roller 10 is adjusted by the height adjusting rod 24 in order to use the nursery boxes 2 having different heights. It can be driven to rotate even if it is moved downwards.
0 is vertically guided by a guide protrusion 49 engaged with a guide hole 48 parallel to the long hole 31. Since the passive gear 32 and the output gear 41 are formed by gears, the rotation transmission is reliable, and the passive gear 32, the upper intermediate gear 36, and the lower intermediate gear 39 are the arms 33 of the vertical link mechanism 46. Since it is attached to the support plate 30 formed with a rotatable width of 34 and 37, the attachment device of the strip roller 10 can be made extremely small, and the floor soil supply device 5
The intervals between the devices such as the seed feeding device 6 provided on the transfer table 1 can be narrowed, and the whole structure can be made compact.

In the second embodiment of FIG. 11, 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 moves. 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. In any case, the output gear 41 is rotated by the passive gear 3
Communicate to 2. Further, the up / down corresponding rotation transmission mechanism X of the second embodiment is also compact because the front / rear width is sufficient to secure the rotation amount of the tension arm 72. Then, the paddy guide 63 located below the feeding roll 56 of the seed feeding device 6
With the parallel link 64, and the vertical position switching device 6
2, the whole seed feeding device 6 is lowered to the dispersal position, the row roller 10 and the pressure suppressing roller 12 are moved upward, and the guide protrusion 49 of the mounting plate 16 is formed at the upper part of the guide hole 48 of the support plate 30 and retracted. When the seedling raising box 2 is supplied to the starting end of the transfer table 1 in this state by engaging with the groove 50 and retracting, the bed soil is supplied by the bed soil supply device 5, and the supplied bed soil is supplied by the rotating brush 8. On the leveled and leveled soil, the seed paddy that was fitted into the horizontal groove 57 of the horizontal axis feeding roll 56 and co-rotated with the horizontal axis feeding roll 56 was dropped and scattered, and then by the irrigation device 22. Receiving irrigation, the soil cover supply device 7 supplies the soil cover, and the rotary brush 8 on the front side of the soil cover supply device 7 sweeps the soil cover that has dropped onto the side wall of the seedling raising box 2 to complete the sowing operation.
