[0017]

[Operation] Next, the operation will be described. The tip of the soil feeding device 17 is exposed to the soil feeding hopper 14, and the hopper 2 of the soil feeding device 17 is exposed.
When the soil is put into No. 6 and the motor 28 is energized, the motor 2
8 rotates the upper rotary shaft 4, rotates the lower rotary shaft 6 of the bucket conveyor via the sprocket 5 and the endless chain 8, and the bucket 9 starts to rotate by the rotation of the endless chain 8, and at the same time the lower rotary shaft 6 is rotated. Of the rotation (rotation of the arm 24) is converted into a linear reciprocating motion by the rod 25 to the input shaft 23 of the one-way rotation transmission clutch 22 and transmitted, and the conveyor belt 20 below the hopper 26 removes the soil in the hopper 26. The bucket 9 that supplies the soil to the soil supply hopper 14, reverses and rises in the soil supply hopper 14, scrapes off the soil, and ascends in the soil supply hopper 14.

When the bucket 9 rises, however, it 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 floor soil supply device 35 to remove the soil. After the supply is completed, when the seedling raising box is supplied to the horizontal transfer table 34 and the bed soil supplying device 35 is energized, the seedling box transferred by the horizontal transfer table 34 reaches below the bed soil supplying device 35 and is not shown. The soil fed by the feeding device is supplied.

Therefore, of the soil that has fallen from the floor soil supplying device 35, the soil that has fallen without entering the seedling raising box enters the hopper 26 of the recovery transport device 37, and the soil in the hopper 26 is the inner surface of the hopper 26. Is guided to reach the conveyor belt 20,
The conveyor belt 20 conveys to the soil recovery hopper 15 and collects it. The soil recovered in the soil recovery hopper 15 is pushed by the descending bucket 9 and passes between the lower parts of the left and right frames 2 and 3, and is scooped up by the reversing bucket 9 and rises.

In the above-mentioned case, the soil charging device 17 and the recovery transport device 37 both use the rod 25 to rotate the lower rotary shaft 6 (rotation of the arm 24) by the one-way rotation transmission clutch 22.
Is transmitted to the rotary shaft 21 of the drive roller 18 by the one-way rotation transmission clutch 22.
0 means intermittent movement.

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 soil is prevented and the bucket conveyor 1 is operated reliably. At this time, if the movement of the conveyor belt 20 and the movement of the bucket 9 are synchronized, clogging is further prevented, and the soil supply hopper 14 and the soil recovery hopper 1 are provided.
The volume of 5 is formed to the size that one bucket 9 scoops to prevent the occurrence of the bridge phenomenon, to efficiently scoop the soil of the bucket 9, and to supply the soil supply hopper 14,
It is also possible to prevent the soil from overflowing from the soil recovery hopper 15.

The conveyor belt 20 is provided below the hopper 26.
Is located, the soil in the hopper 26 is totally collapsed by the impact of the movement of the conveyor belt 20, and the bridge phenomenon does not occur. In addition, since the impact on the soil in the hopper 26 becomes large due to the intermittent movement of the conveyor belt 20, the hopper 2
Soil does not adhere to the inner surface of 6. Further, in the rotation transmission method of chain, belt, etc., the rotation direction of the lower rotary shaft 6 and the rotation direction of the drive roller 18 do not match, and it is necessary to twist the structure. Although it is not possible to easily attach / detach 17 and the collecting transport device 37, according to the present invention, the soil loading device 17 and the collecting transport device 37 can be attached / detached simply by attaching / detaching the rod 25, and the main body of the lifting conveyor 1 can be easily transported. You can

Therefore, in the soil feed switching adjusting device 42 provided at the feeding port 41 of the hopper 26 of the soil feeding device 17, the vertical turning operation lever 53 is moved to the lower end of the engaging portion 55 in the left and right direction all at once in the arrow A direction. When the shaft 52 is rotated about its center, the vertical shaft 52 is rotated to rotate the horizontal shaft 52,
The rod 51 rotates in the direction of arrow B, and the engaging rod 49 is fixed to the tip of the rod 51. Therefore, the engaging rod 49 moves along the semicircular arc line centered on the horizontal axis 52.

Rolls 50, 50 are axially attached to the engaging rod 49, and they are engaged between the horizontal plate portion 47 and the receiving plates 48, 48, and the rolls 50, 50 are the horizontal plates. While sliding between the portion 47 and the receiving plates 48, 48, it moves up along a locus of C on the semi-circular arc line. That is, since the rolls 50, 50 are engaged between the horizontal plate portion 47 of the vertical switching plate 43 and the receiving plate 48 and perform the above-described movement, the upper movement of the roll 50 causes the upper surface of the roll 50 to move to the horizontal plate portion. The lower surface of 47 is pushed upward (in the direction of arrow D) to raise the vertical switching plate 43. The vertical switching plate 43 is formed in a vertical flat plate shape, and is sandwiched between the vertical plate 44 of the front plate 40 of the hopper 26 and the inner end of the support plate 46, so that the vertical switching plate 43 smoothly rises vertically, and the conveyor belt 20 A large input port 41 is formed between the upper surface and the lower end of the so that a large amount of soil is fed out.

However, when the vertical turning operation lever 53 is swung up to the upper end in the direction of the arrow E at once, the left-right direction shaft 52 is moved.
Since the roll 50 descends via the rod 51 and the engaging rod 49 and the receiving plate 48 of the vertical switching plate 43 is pushed down,
The vertical switching plate 43 smoothly descends vertically, and the conveyor belt 20
A small inlet 41 is formed between the upper surface and the upper surface, and the state is switched to a state in which a small amount of soil is supplied.
