BRIEF DESCRIPTION OF THE DRAWINGS FIG.
Is a bucket conveyor of the soil supply device, and has a pair of right and left right frames 2 and left frames 3. The left and right frames 2, 3 are formed to be long in the up-down direction and provided in parallel. A motor 28 is provided on one of the upper left and right frames 2 and 3, and the output shaft of the motor 28 is the upper rotation shaft 4 in the left and right direction. Axle on one of the other. Sprocket 5 between the left and right side frames 2 and 3 at both ends of the rotary shaft 4 is
Are fixed respectively.

[0007] At the lower part of the left and right frames 2 and 3, both ends of a left and right lower rotation shaft 6 that is paired with the upper rotation shaft 4 are journaled. A sprocket 7 that is paired with the sprocket 5 is fixed to an end side, and an endless chain 8 is wound between the sprocket 5 and the sprocket 7, and a bucket 9 on the outer periphery of the endless chain 8 for raising sieve soil. Are mounted at predetermined intervals.

The bucket 9 has a vertical plate 10 parallel to the endless chain 8 and a bottom plate 11 connected to the lower edge of the vertical plate 10.
And the side plate 12 connected to the side of the bottom plate 11. The bottom plate 11 is formed at an angle smaller than 90 degrees with respect to the vertical plate 10. That is, when the bucket 9 is lifted by the endless chain 8 and flipped and thrown at the upper circling portion, the bottom plate 11 of the bucket 9 is inclined forward and downward, and has an angle at which the soil on the bottom plate 11 is discharged. Formed.

A left-right handle 13 formed by a horizontal rod is fixed to the upper ends of the left and right frames 2 and 3 so that an operator can push and pull the entire handle 13 with the handle 13.

However, the lower portions of the left and right frames 2 and 3
The soil feed hopper 14 of the sieve soil after side, wherein each provided with soil collection hopper 15 before the side of the lower part of the left and right side frames 2 and 3, the soil feed hopper 14 and soil collection hopper 15, the bucket 9 Are communicated at the part of the reversing part 16 where the part is reversed. That is, the falling bucket 9 is the soil recovery hopper 1
5 passes between the left and right frames 2 and 3 and is inverted in the soil supply hopper 14 to scoop up the soil and rise.

The soil supply hopper 14 is provided with a detachable auxiliary supply / transport device 17. The auxiliary supply / conveyance device 17 wraps the conveyance belt 20 between the driving roller 18 and the passive roller 19, and rotates the rotation shaft 2 of the driving roller 18.
1 is provided with a one-way rotation transmission clutch 22, and an input shaft 23 of the one-way rotation transmission clutch 22 and an arm 24 provided on the lower rotation shaft 6 are connected by a rod 25. 2
Hopper provided above the conveyor belt 20 is 6, 29 support legs, 30 seal member, 31 a scraper, 32 is transported wheel, auxiliary subjected <br/> supply conveyor to the axis of rotation of the transport wheels 32 in the embodiment The device 17 is engaged (FIG. 3) .

[0012] Thus, the upper front of the left and right side frames 2 and 3 provided the supply trough 33, lower end soil feeding test provided at a position above the horizontal transfer table 34 for transferring the seedling box feed trough 33
The feeder 35 (which can also be used as a cover feeder) faces the floor soil hopper 36.

A transporting device 37 for recovery is provided below the soil feeding and supplying device 35 . Since the recovery transporting device 37 is configured in the same manner as the auxiliary supply transporting device 17, it will be described with the same reference numerals.
The hopper 26 of the transfer device 37 for collection is located below the soil feeding and supplying device 35 and also serves as a guide plate for guiding the fallen soil to the transport belt 20. The soil supply hopper 14
In some cases, a support leg in the front-rear direction may be provided on the lower surface of the soil recovery hopper 15.

[0014]

Next, the operation will be described. With the front end of the auxiliary supply / conveyance device 17 facing the soil supply hopper 14, the auxiliary supply / conveyance device 1
When the sieve is put into the hopper 26 of No. 7 and the motor 28 is energized, the motor 28 rotates the upper rotating shaft 4 and the lower rotating shaft 6 of the bucket conveyor via the sprocket 5 and the endless chain 8 to rotate the endless chain. The rotation of the bucket 8 starts the rotation of the bucket 9, and at the same time, the rotational motion of the lower rotary shaft 6 (the rotation of the arm 24) is converted into linear reciprocating motion by the rod 25 to the input shaft 23 of the one-way rotation transmitting clutch 22. The transport belt 20 below the hopper 26 is
The inside sieve is supplied to the soil supply hopper 14, and the bucket 9, which is inverted and rises in the soil supply hopper 14, scrapes the soil and rises inside the soil supply hopper 14 while scooping.

When the bucket 9 rises, the thrown soil is thrown at the upper position, and the thrown soil flows down on the supply gutter 33 and enters the floor soil supply hopper 36 of the soil feeding / supplying device 35 .
When the supply of the soil is completed and the seedling box is supplied to the horizontal transfer table 34 and the soil feeding supply device 35 is energized before that, the seedling boxes transferred by the horizontal transfer table 34 are moved to the soil transfer supply device 35.
, And is supplied with soil fed by a feeding device (not shown).

Thus, of the soil that has fallen from the soil feeding / supplying device 35 , the soil that has fallen without entering the seedling raising box enters the hopper 26 of the collecting and transporting device 37, and the soil in the hopper 26 is the inner surface of the hopper 26. And is transported to the soil recovery hopper 15 to be collected. The soil collected in the soil collection hopper 15 is pushed by the descending bucket 9 and is moved to the left and right frames 2, 3.
And is scooped up by the reversing bucket 9 and rises.

In the above case, both the auxiliary supply transfer device 17 and the recovery transfer device 37 convert the rotational movement of the lower rotary shaft 6 (rotation of the arm 24) into a one-way rotation transmitting clutch 22 by the rod 25 into a linear reciprocating movement. Of the reciprocating motion, the one-way rotation transmission clutch 22 transmits only one-way rotation to the rotating shaft 21 of the drive roller 18, so that the transport belt 20 moves intermittently.

Therefore, since a large amount of soil is not conveyed to the soil supply hopper 14 and the soil recovery hopper 15 at one time, clogging of the soil is prevented and the bucket conveyor 1 is reliably operated. At this time, if the movement of the conveyor belt 20 and the movement of the bucket 9 are synchronized, the clogging is further prevented, and the soil supply hopper 14 and the soil recovery hopper 1
5 can be made small so that the amount of soil to be scooped by the bucket 9 can be made more efficient, and the soil can be prevented from overflowing from the soil supply hopper 14 and the soil recovery hopper 15.

The transport belt 20 is located below the hopper 26.
Is located, the soil in the hopper 26 is entirely collapsed by the impact of the movement of the conveyor belt 20, and the bridge phenomenon does not occur. Further, since the impact given to the soil in the hopper 26 due to the intermittent movement of the conveyor belt 20 becomes large, the hopper 2
No soil adheres to the inner surface of No. 6. The delay in the rotation transmission method such as a belt, not match and the rotation direction of the rotation direction of the drive roller 18 of the lower rotating shaft 6, and twisting it becomes necessary not only structure becomes complicated, the auxiliary supply conveyance Although the device 17 and the collecting and transporting device 37 cannot be easily attached and detached, in the present invention, the auxiliary supply / transporting device 17 and the collecting and transporting device 37 can be attached and detached simply by attaching and detaching the rod 25, and the main body of the bucket conveyor 1 can be transported. Easy.
