4, the moving shaft 42 does not move because the engaging shaft 47 is engaged with the engaging member 48, and the discharge port 27 of the bottom plate 28 of the case 23 moves.
However, as shown in FIG. 5, the seed 11 falls into the hose 32 through the outlet 27 in conformity with the seed fitting hole 30. While the seed 11 is falling in the hose 32, the case 23 is further moved in the direction a so that the dropping hole 34 of the dropping part 33 and the through hole 6 of the paper pot 1 are sown so as to match (FIG. 6). .

However, when the seeding hole 30 and the seed fitting hole 30 are sown so as to coincide with each other, the regulating member 51 is in contact with the mounting arm 41 of the shutter 29 (FIG. 5), and the case 23 is further inflated. The communication port 27 and the discharge port 2
When the case 23 moves to the state shown in FIG. 12, the washer 52 stops the movement of the shutter 29 when the case 23 moves to the state shown in FIG. 12 (FIG. 5, FIG. 6, FIG. 7, FIG. 8, FIG. 9, FIG. 10, FIG. 11). After stopping, only the hopper 25 and the bottom plate 28 move in the opposite direction to the shutter 29, the leveling brush 26 above the seed fitting hole 30 retreats, and the seed 11 is placed in the seed fitting hole 30. Fit again.

Although the movement of the pot sheet 1 is continued, the case 23 repeats the movement in the direction A after moving in the opposite direction as a whole. Again, the pot sheet 1 and the seed supply device 22 both move in the direction a at the same speed again, and perform the same sowing operation as described above. However, when the above operation is repeated four times, the number of vertical pots in one pot sheet 1 as a whole is usually 16, so that the entire pot can be seeded. Therefore, since the sensing roller 58 is provided at the front end of the support arm 57 of the engaging member 48, the rear end 55 of the preceding seedling raising box 8 fitted with the pot sheet 1 and the front end of the following seedling raising box 8 At the interval L between the shutter 56 and the portion 56, the sensing roller 58 descends, and the engaging member 48 retreats to a position where the engaging shaft 47 of the moving shaft 42 does not engage to disengage the clutch. No relative movement between the bottom plate 29 and the bottom plate 28 is performed, and no seeding is performed.

In the seeding operation, the seeds 11 are put in a row in the seed fitting groove 31, and then the flat brush 26 is retracted and fitted into the seed fitting hole 30. When the upper seed 11 enters the bridge state, the seed fitting groove 31
But it will not fit in the brush
6 are provided at predetermined intervals in front and back, and each leveling brush 26
The bridge prevention body 53 formed by an axial member parallel to the leveling brush 26 is provided at an intermediate position before and after.
The seed 11 on the seed fitting hole 30 is agitated by the relative movement of the shutter 29 and the bridge preventing body 53, and the seed 11 in the lowermost layer is agitated, whereby the bridge can be reliably prevented, and the various child fitting holes 30 can be prevented. The seed 11 is always fitted to the soot to improve the sowing accuracy.

Further, since the shaft-shaped bridge preventing members 53 are provided between the leveling brushes 26 in a substantially parallel state, the bridge preventing members 53 and the shutter 29 can be easily brought into a relative movement relationship. The bridge of the seeds 11 can be reliably prevented by good stirring. That is, the leveling brushes 26 long in the left-right direction are provided at predetermined intervals in the front and rear directions, and a bridge preventing body 53 formed by an axis member parallel to the leveling brushes 26 is provided at an intermediate position before and after each leveling brush 26. Since the seeds 11 are provided, the seeds 11 stored between the leveling brushes 26 are stirred by the bridge preventive body 53 to prevent the occurrence of bridges, so that the seeds are surely sown. Also, the shutter 29
Since the bridge prevention member 53 is provided in a substantially parallel state between the leveling brushes 26 which are long in the cross direction with respect to the sliding direction of
Each time the shutter 29 slides, it comes into contact with the seed 11, so that the occurrence of a bridge can be reliably prevented. Also,
As described above, the seed fitting hole 30 is formed at the bottom of the seed fitting groove 31 at a depth on the upper surface of the shutter 29 where substantially one seed 11 fits, and the lower end of the leveling brush 26 is Since the bottom of the fitting groove 31 is slidably contacted, the leveling brush 26 prevents the seed fitting groove 31 from being clogged, and the bridge preventing body 53 prevents the occurrence of bridges.
6 and the bridge preventing body 53 can be sowed reliably by a synergistic action.

Since the bridge preventing member 53 is provided at a position lower than the seed 11 from the upper surface of the shutter 29, the seed 11 at the bottom of the seed fitting groove 31 is necessarily relatively moved by the sliding of the shutter 29. Stirring is performed by the bridge preventing body 53, so that the occurrence of bridges can be prevented.
Thus, the seeds 11 are coated with vegetable seeds such as lettuce, and even if they are the same varieties, not only the size of the seeds themselves is different, but also the size is different depending on the thickness of the coating. . Then, after sowing lettuce, when sowing Chinese cabbage seeds, remove the hopper 25 from the case 23, remove the shutter 29 on the bottom plate 28,
The shutter is replaced with a shutter 29 having a seed fitting hole 30 that matches the size of another seed 11.

In this case, since the space 67 is formed between the shutter 29 and the front plate 35, the hopper 25 is removed, the upper surface of the shutter 29 is exposed, and the seed receiving box 66 is moved from above into the space 67. (See FIG. 16), and the engaging portions 69 of the seed receiving box 66 are engaged with the side plates 68, 68, so that the opening 70 of the seed receiving box 66 is flush with the upper surface of the shutter 29. In this state, when the brush 71 sweeps over the shutter 29, the seed 11 is swept into the seed receiving box 66 from the opening 70, and the residual seed 11 on the shutter 29 can be easily removed. The support arm 57 is provided with a manual switching device 64 for manually engaging and disengaging the clutch.
When the pin 73 is rotated rearward, the pin 73 moves in the arc hole 72 and contacts the lower surface of the support arm 57. When the pin 73 further moves in the arc hole 72, the pin 73 moves up the support arm 57. Then, the engagement member 48 is positioned at the engagement position with the engagement shaft 47 (clutch is engaged), and the engagement member 48 causes the relative movement between the shutter 29 and the bottom plate 28 to fit the seeds of the shutter 29. The seeds 11 fitted in the holes 30 are discharged.

When the manual switching device 64 is engaged at the start of the operation, the test of the seeding operation can be performed without transferring the pot sheet 1. In the second embodiment of the projection group 75 shown in FIG. 18, the upper surface of the floor soil 4 of each pot 2 of the pot sheet 1 is formed by pressing projections 75a, 75b, 75c of the mounting plate 77 gradually descending by circular movement. Is pressed,
The front pressing protrusion 75a and the rear pressing protrusion 75b of the pressing protrusions 75a, 75b, and 75c are configured to be retracted, so that when the descent is performed, the side portion of the pot 2 is not crushed, and Invade inside 2. That is, A in FIG.
When the mounting plate 77 is located at the position, the sensor shaft 82 is lowered by the elastic force of the descending spring 86, and the traction pin 83 and the mounting shaft 81 are relatively close to each other, so that the traction spring 80 is loosened and the pressing protrusions 75a, 75b Retreat with the vertical axis 76 inclined,
When reaching the position above the pot 2, the case 23 is lowered and the mounting plate 77 is at the position B, and the traction pins 83 of the sensor shaft 82
Pulls the pulling spring 80 to bring the vertical axis 76 upright, and presses each pot 2.

Therefore, the seeds can be seeded by simultaneously pressing the plurality of pots 2 in the transfer direction. Also, if the mounting plate 77 is B
Even if it is at the position, when the rear end of the preceding seedling raising box 8 passes,
The descending spring 86 moves the sensor shaft 82 downward, and the seedling raising box 8 is moved.
The sensor body 84 moves down below the upper surface of the side wall of the traction spring 83, and the traction pin 83 and the mounting shaft 81 come close to each other, so that the tension traction spring 80
Acts in the same manner as the loosening rod to rotate the vertical axis 76 about the horizontal axis 78, and the front pressing protrusion 75a and the rear pressing protrusion 75b
Is retracted (regardless of the number of front and rear projections, the front pressing projection 75
a and the rear pressing protrusion 75b may be retracted). Then, when the sensor body 84 rides on the subsequent seedling raising box 8, the pulling pin 83 of the sensor shaft 82 that has been moved up pulls the pulling spring 80 to bring the vertical axis 76 upright and press each pot 2. As described above, the front pressing protrusion 75a and the rear pressing protrusion 75b of the pressing protrusions 75a, 75b, and 75c are configured to be retracted, so that even if the vertical width of the case 23 is reduced, the pressing is surely performed. As a result, the entire frame 24 of the seed supply device 22 can be reduced in size.
