Furthermore, an adjustment bolt 70 is provided on the plate 44a.

Punches 49a are cut in the horizontal frame 48 and are movable up and down to form planting holes for sowing seeds and planting seedlings in independent blocks B. The number corresponds to the number in the width direction. Further, the vertical movement stroke of the forming section 40 is set so that the cutter 41 reaches the conveyor belt, and the block retainer is set so as to maintain a distance from the conveyor belt equal to the thickness of the block.

The entire molding section 40 moves up and down, and a crank arm 52 provided on the shaft 35a of the chain wheel 35 is pivotally attached to a frame 50 of the molding section 40, and this frame 50 moves up and down along a guide 51. I am able to move. A spring is interposed between the frame 50 and the molded part 40, so that even if foreign objects such as stones are present, the work will not be hindered.

Further, the seed supply device 60 has a seed supply plate 62 that reciprocates along the inclined bottom surface 61a of the hopper 61, and this seed supply plate 62 has holes 62a corresponding to the number of blocks B. One or several seeds are stored in the holes 62a for each block B, and when the seed supply plate 62 has moved to the supply hole 63 drilled in the hopper 61a, the seeds are sent from the nozzle 65 through the supply pipe 64 to the hole 62a of each block B. let it fall.

The seed supply plate 62 is connected to a swinging drive rod 66 that is pivotally supported on the machine frame 10.
The other end is connected to an arm that is cranked by the rotation of the motor 20, and is constantly pulled by a tension spring 67 so that the seed supply plate 62 moves above the hopper 61.

Next, the operation of forming block B shown in FIG. 1 using the soil block manufacturing apparatus of the present invention will be explained. First, soil suitable for the soil block is stored in the soil hopper 30, and a certain amount of soil is allowed to flow out from the soil supply port 31 onto the conveyor belt 16. When the motor 20 is driven in this state, the rotation of the crank arm 22 causes the connecting rod 23 to reciprocate, causing the ratchet pawl 25 to rotate the ratchet wheel 15 when the swinging rod 24 is pulled.
When being pressed, let the ratchet pawl 25 play. Rotation of the ratchet wheel 15 drives a pulley 14 coaxial with the ratchet wheel 15, and the conveyor belt 16 is intermittently fed. It works in the same way when using a cam clutch. The stroke of this intermittent feed is determined by the width dimension of block B, and conveyor belt 1
6 moves on the bottom surface of the soil hopper 30, so soil is continuously taken out from the soil supply port 31. This soil supply port 3
A sliding arm 32 near the soil supply port 31 is moving in an arc in conjunction with the rotation of the motor 20, so it moves as if applying it to the surface of the soil flowing out from the soil supply port 31. This prevents it from collapsing. This sliding arm 32 makes an arcuate motion and reciprocates as the swinging rod 33 swings due to the rotation of the crank arm 34a.

Furthermore, the crank arm 52 rotates via the chain 37 and the chain wheel 35 in rapid motion with the intermittent feeding of the conveyor belt 16, and thereby the forming part 40 moves up and down, and moves downward against the soil on the conveyor belt 16. Then, the cutter 41 makes slits in the soil. The horizontal blade 41 is cut by the vertical stroke of the cutter 41.
B and the vertical blade 41a slit the continuous soil, and after the next feed, the horizontal blade 41b separates it from the continuous soil to form an independent block B. The slit is made by the downward movement of the cutter 41, and the block retainers 42, 43 are pressed by springs 46, 49.
Since the block soil is pushed by the adjustment bolt 70 while being bounced by the conveyor belt 16 while maintaining a distance between it and the conveyor belt 16, the surface of the block is pushed appropriately and hardened. Further, the height of the block B is adjusted by adjusting the adjustment bolt 70. As the cutter 41 moves upward, the block retainers 42 and 43 also move upward, but the block retainers 42 and 43 are held by the push springs 46 and 4.
9 remains compressed to a certain extent and does not move up together with the cutter 41, so the cutter 41 moves toward the block B.
Block retainers 42 and 43 hold down the surface of the block group until they are separated from the block. Therefore, Katsuta 4
The soil of the block is not brought up by the upward movement of 1,
There is no shape disturbance at all.

A punch 49a cooperating with the cutter 41 punches a hole in the formed block B, and the seed grains in the hopper 61 are fed into the hole by the seed supply plate 62 into each supply pipe 64, and then into each nozzle 65. Seed grains are supplied from This seed supply plate 62 reciprocates linearly along the bottom surface of the hopper 61 as a swing drive rod 66 pivotally supported on the machine frame 10 swings by the rotation of the motor 20, and reaches the bottom of the hopper 61. In the position state, many seeds are placed on the seed supply plate 62, but since the seed supply plate 62 is in the raised state, most of the seeds rotate low, and only the seeds in the holes 62a reach the supply hole 63. and falls from the supply pipe 64 to the nozzle 65.

(E) Effects of the Invention As is clear from the above description, according to the soil block manufacturing apparatus of the present invention, block holders that move up and down with the cutters are arranged in front and behind the cutters along the feeding direction, and this block holder is Since the structure is configured such that the movement of the cutters is delayed with respect to the upward movement of the cutters, it is possible to prevent the soil from being carried away by the movement of the cutters forming the block, and it is possible to manufacture blocks with accurate shapes.
