It is an object of the present invention to provide a seedling box transfer processing machine capable of easily performing the seedling box transfer processing. A third object of the present invention is to provide a seedling box transfer processing machine in which the lateral width of the seedling box transfer processing machine with respect to the traveling direction is narrowed so that movement of the machine such as passing through a doorway of a house can be easily performed. It is in.

A fourth object of the present invention is to form a traveling section by a crawler traveling body, make a substantially one-point turn with respect to the ground, and turn the machine body in a direction opposite to this turn, thereby providing a front-rear transport mechanism and a vertical and horizontal mechanism. It is an object of the present invention to provide a seedling box transfer processor that enables only a traveling portion to change direction without changing the direction of a transfer mechanism, prevents contact with surrounding objects, and enables movement in a narrow space.

Further, when the seedling boxes N are used for collecting the seedlings N, the laid many seedling boxes N are simultaneously transferred from the ground to the front-rear transfer mechanism 6, and the rearward movement by the front-rear transfer mechanism 6 and the vertical and horizontal transfer mechanism are performed. The seedling box N is transferred to the delivery position on the vertical and horizontal transport mechanism 5 by the backward movement of 5, and the horizontal movement of the vertical and horizontal transport mechanism 5 is moved from the delivery position to the base position laterally in the left-right direction. Even when the vertical and horizontal transport mechanisms 5 and the front and rear transport mechanisms 6 are provided and the left and right widths of the entire machine are wide, the vertical and horizontal transport mechanisms are provided because the machine body 31 can be swiveled with respect to the traveling unit 29. By changing the longitudinal direction of the front and rear transport mechanism 5 and the front and rear transport mechanism 6, it is possible to easily move and handle the machine in a house or the like.

A second specific means for solving the problem in the present invention is that, in addition to the first specific means, the front / rear transport mechanism 6 and the vertical / horizontal transport mechanism 5 are protruded right and left outward from the traveling section 29. It is to be established. Thereby, a large number of seedling boxes N can be placed and transported by the front-rear transport mechanism 6 and the vertical / horizontal transport mechanism 5, and the longitudinal direction of each of the mechanisms 5, 6 can be changed by turning the machine body. The space required for the movement of the machine can be reduced, and the movement can be performed easily.

A third specific means for solving the problem of the present invention is that, in addition to the first or second specific means, the main body 31 can be turned at least 90 ° with respect to the traveling portion 29. It was that. Thereby, even when the vehicle passes through a narrow space such as a doorway of a house, the machine body 3

It is possible to reduce the lateral width of the machine with respect to the advancing direction by turning the two mechanisms by turning the longitudinal direction of the two mechanisms toward the advancing direction, and it becomes easy to pass through the entrance.

A fourth concrete means for solving the problem of the present invention is that the traveling portion 29 has a pair of crawler traveling bodies 32 in addition to any one of the first to third specific means. And a turning control unit for turning the crawler running body 32 substantially one point with respect to the ground, and a turning control unit for turning the machine body 31 in the opposite direction in synchronization with the turning of the crawler running body 32. is there. According to this, even when the seedling box transport processing machine is moved right and left at the front and rear end portions of the house, the crawler traveling body 32 is turned with respect to the ground so as to turn the traveling direction to the left and right, and synchronized therewith. By rotating the machine body 31 in the opposite direction with respect to the crawler traveling body 32, only the crawler traveling body 32 is turned while the front-rear transportation mechanism 6 and the vertical and horizontal transportation mechanism 5 are directed in the front-rear direction. It is possible to move. Therefore, even in a narrow space at the front and rear ends of the house, the seedling box transfer processing machine can be moved without obstruction of surrounding objects. Further, after the right and left movement, the traveling direction of the crawler traveling body 32 can be turned back and forth again without changing the directionality of the forward and backward transport mechanism 6 and the vertical and horizontal transport mechanism 5 by the operation opposite to the above.

It is supplied to the delivery mechanism 7. The transfer mechanism 7 moves the central feed portion 5 of the vertical and horizontal transport mechanism 5 from the rear position.
Transfer to C. In the vertical and horizontal transport mechanism 5, the middle and left and right stoppers 4
2L and 42R are in the operation position, and the conveyor structure of the central feed portion 5C moves forward, so that the seedling box N delivered from the delivery mechanism 7 abuts on the middle front stopper 42F and then the middle rear stopper 42B. Projecting to the operating position, the middle right stopper 42R is retracted, the conveyor structure of the central feed unit 5C moves backward, and the conveyor structure of the right feed unit 5R moves forward, so that the seedling box N is moved to the middle front stopper. While being guided by 42F and the right rear stopper 44B, the sheet is distributed and conveyed to the delivery position on the right feeder 5R.

When the four seedling boxes N are supplied on the right feeding portion 5R, the middle right stopper 42R is placed at the operation position and the middle left stopper 42R is placed at the retreat position, and the conveyor of the center feeding portion 5C and the left feeding portion 5L is moved. Move the structure forward, and
The four seedling boxes N are transported to the transfer position on L. A total of 8 seedling boxes N each having 4 seedling boxes N on the left and right feeding sections 5L and 5L
Is prepared, the left and right feeders 5L and 5L and the front and rear conveyance means 18 of the front and rear conveyance mechanism 6 are simultaneously moved forward, and all the seedling boxes N are moved forward from the vertical and horizontal conveyance mechanism 5 to move the front and rear conveyance at the ascending horizontal position. Hand over the means 18.

Then, the lifting / lowering means 11 is operated, and the front / rear conveyance means 18 is tilted downward from the rising horizontal position to the front downward inclination position. When the front / down inclination position is reached, the working apparatus A is moved backward and forward and backward. The belt conveyor 38 of the means 18 is forwarded to discharge all the seedling boxes N to the ground,
The backward movement of the working device A is stopped in a state where the front and rear transport means 18 is separated from the released seedling box N by a predetermined distance.

Thereafter, the horizontal moving means 10 is actuated to move the front / rear conveying means 18 horizontally forward, and the contact means 23 of the box aligning means 16 disposed at the front thereof is brought into contact with the whole seedling box N which has released. The seedling box N is pushed forward until it comes into contact with the preceding laid seedling box N, so that the front and rear positions of all the seedling boxes N are aligned, and the interval between the front and rear seedling boxes is reduced. After the horizontal moving means 10 is reversely operated to retreat the front-rear transport means 18 or while being retracted, the elevating means 11 is reversely operated,
The forward / backward transporting means 18 is returned to the raised horizontal position at which the seedling box N can be transferred from the vertical / horizontal transporting mechanism 5, and the above process is repeated.

A sidewalk having a width substantially equivalent to the width of the central feeding portion 5C is formed between the four left and right seedling boxes N laid.
During the laying of the seedling boxes N after the transfer of the seedling boxes N from the vertical and horizontal transport mechanism 5 to the front and rear transport means 18, the seedlings to be laid next are laid on the left and right feed portions 5L and 5R of the vertical and horizontal transport mechanism 5. Box N
Can be supplied, thereby shortening the cycle time of laying the seedling boxes and increasing the work efficiency.

When the seedling box laying machine has moved to the rear end in the house, the box supply device B is separated from the working device A and remains on the vertical and horizontal transport mechanism 5 of the working device A and the front and rear transport means 18. Existing seedling box N is laid only by the working device A. In this case, if the delivery mechanism 7 is folded by the third retreat moving means 144 and the rear end of the delivery mechanism 7 is retracted forward, the moving space behind the working device A can be enlarged, and It is also possible to lay the seedling box N to a position further retracted in the inside.

Then, after laying the seedling box N, the working device A changes direction and is moved to another house or laying area, and after the movement, the box supplying device B is connected again. When laying a new seedling box N in parallel with the existing seedling box N, the working device A moves to the front end in the house after laterally moving at the rear end position in the house. In this case, by driving the left and right crawler traveling bodies 32 of the work traveling machine body A2 in the left and right directions, the crawler traveling bodies 32 are turned substantially one point with respect to the ground to change the direction of the traveling platform 29, and in synchronization with this. The main body 31 is turned around the traveling platform 29 in the opposite direction. That is,
According to the turning angle of the traveling platform 29 with respect to the ground, the traveling control unit and the pivoting control unit perform synchronous control so that the machine body 31 pivots counterclockwise with respect to the traveling platform 29 by that amount.

Accordingly, the machine main body 31 and the vertical / horizontal transport mechanism 5 and the front / rear transport mechanism 6 supported by the machine main body 31 are turned only in the traveling platform 29 while keeping the direction unchanged, and are perpendicular to the laying direction of the seedling box N. Thus, even if the vertical and horizontal transport mechanism 5 and the front and rear transport mechanism 6 are long in the left-right direction, the space for moving between the laying areas can be reduced. When the work apparatus A is passed through the entrance of the house, when the entrance is narrow, the machine body 31 is turned by 90 degrees with respect to the traveling platform 29 and the horizontal direction (longitudinal direction) of the vertical and horizontal transport mechanism 5 and the front-rear transport mechanism 6. To work direction A
The horizontal width (horizontal width) with respect to the traveling direction is reduced. The traveling platform 29 can easily pass through the entrance by traveling the traveling platform 29 in this manner. In this case, the turning control of the machine body 31 is independently performed by the turning control unit, or the control of synchronizing the turning of the traveling unit 29 and the turning of the machine body 31 in the opposite direction is performed in the same manner as described above. To do.

In this case, as shown in FIGS. 32 and 33, the box pick-up mechanism 17 is moved backward and retracted by the first retreating means 66, and the front end of the front-rear transporting means 18 is moved by the second retreating means 120. By moving and retreating rearward, and by retreating the rear end of the delivery mechanism 7 forward by the third retreat moving means 144, the left-right width in the traveling direction of the working device A is further narrowed, and the passage of the entrance is made easier. It is possible.

Also, when the working device A is stored in a warehouse or the like, the storage space can be made smaller by setting the box pick-up mechanism 17, the forward / rearward transport means 18, and the delivery mechanism 7 to the retracted positions as described above. Next, a method for collecting seedling boxes in the case where the seedling box transfer processing machine described in the above embodiment is a seedling box collecting machine will be described.

Only the working device A is moved to the end of the laying area in the house, the box pick-up mechanism 17 is opposed to the laid eight seedling boxes N in one horizontal row, and the seedling box N is detected by the front end sensor 53.
