It is configured to stop and hold.

The illustrated embodiment is constructed as described above, and its operation will be explained below.

First, when the motor 19 of the box conveying device 2 is driven, the two chains 15, 15 travel in the direction of arrow b.

Therefore, by operating the cylinder 33 of the box feeding device 4, the pair of front and rear rack and pinion mechanisms 36, 36
When the receiving plate 25 and the locking piece 27 are relatively moved in opposite directions through the can be supplied.

The seedling box 1 thus supplied onto the chains 15, 15 is transported to a fixed position below the pine loading device 9 by the chains 15, 15 traveling in the direction of the arrow b, and then pushed to the stopper of the stopper device 8. The piece 75 stops at the above-mentioned fixed position.

On the other hand, a receiving plate 4 in a pine supply device 7 at the bottom of a magazine 6 that stores seedling pine a... in a stacked manner.
6, 46 as shown in FIG.
When the piston rod 55 of the cylinder 54 is made to protrude inwardly and the protruding movement is transmitted to the gear device 56 and the pair of left and right rack and pinion mechanisms 57, 57, the rack and pinion mechanisms 57, 57 In operation, as shown in Figure 5, the receiving plate 4
At the same time as needles 6 and 46 move back, needles 48 and 4
8 advances, and the needles 48, 48 pierce and hold a plurality of seedling growing pines a at the bottom of the stacked pine A except for the seedling growing pin a at the bottom layer, so that the seedling growing pines a at the bottom layer are held. is separated into one sheet and falls onto the belt 41 of the mat conveying device 5.

Next, when the motor 38 of the pine conveying device 5 is driven to cause the belt 41 to run in the direction of the arrow c, the seedling pine a on the belt 41 is transferred to the horizontal receiving plate 60 of the pine loading device 9, 60.

Next, as shown in FIG.
As shown in FIG. 7, the receiving plates 60, 60 are tilted as shown in FIG. When 69 is moved downward, the above-mentioned seedling growing pine a is pushed into the seedling growing box 1 while being guided by the left and right receiving plates 60, 60.

Next, as shown in FIG. 9, the above-mentioned push-in plate 69 is moved through the piston rod 71 of the cylinder 70 for lifting and lowering the push-in plate and the cylinder 66 for rotating the receiving plate.
and return the receiving plates 60, 60 to their original positions.

Next, when the cylinder 78 of the stopper device 8 shown in FIG. 10 is operated and the piston rod 81 of the cylinder 78 is moved downward, the stopper piece 75 rotates counterclockwise about the pivot 73, so that it is positioned at a fixed position. After the seedling raising pine a has been pushed in, the seedling raising box 1 is transferred to the chains 15, 15 of the box conveying device 2.
As shown in FIG. 11, the material is transported toward the next process line, such as a seeding line (not shown).

Next, as shown in FIG. 12, when the empty seedling growing box 1 in which the seedling growing pine a has not yet been pushed is transported to a predetermined position, the fluid supply to the piston rod side chamber of the cylinder 78 in the above-mentioned stopper device 8 is cut off. Then, the stopper piece 75 and the piston rod 81 return to their normal original positions due to the restoring force of the compression spring 80, and are positioned in a fixed position relative to the empty seedling growing box 1.

Thereafter, by repeating each of the above-mentioned operations, the single seedling growing pine a, which has been separated one by one from the stacked pine A, is successively pushed into the seedling growing box 1 at the placement part, that is, the pushing part of the pine loading device 9. After completion of pushing, the seedling raising box 1 is transported to a soil covering line via a seeding line.

In short, after the seedling pine a in the magazine 6 is separated one by one by the pine feeding device 7 described above, the separated single seedling pine a is mechanically raised into seedlings by the pine loading device 9 serving as a pushing part. Since it is pushed into the box 1, compared to conventional artificial methods, the holding force and pushing force against the seedling pine a are always constant, which has the effect of preventing damage and loss of the seedling pine a. There is.

In addition, as shown in the example, the seedling growing pine a on the left and right receiving plates 60, 60 held in a horizontal position
is set as a guide for pushing by rotating the receiving plates 60, 60 in an inclined manner, and by lowering the pushing plate 69 located above the pine a, the above-mentioned receiving plates 6
If the structure is such that the seedling pine a is pushed into the lower seedling growing box 1 while being guided to center it at 0.60°, even if the seedling pine is made of lock fiber which is relatively easily damaged, the same pine a
There is an effect that the seedlings can be more effectively pushed into the seedling raising box 1 and automatically loaded.

In addition, as shown in the embodiment, the upper rack 45
and a pinion 44 interposed between the lower rack 43
The rotation of these upper and lower racks 45, 43
When the receiving plate 46 on the lower rack 43 side protrudes to the bottom of the magazine 6, the needles 48 on the upper rack 45 side are moved away from the seedling pine a, and the needles 48 on the lower rack 43 side are moved in opposite directions. When the receiving plate 46 retreats from the lower part of the magazine 6, the needle 48 on the upper rack 45 side is inserted into the seedling growing pine a in the magazine 6, and while holding the entire laminated pine A, the single seedling growing pine in the lowest layer is a can be separated into one piece and dropped, and in this way a pair of rack and pinion mechanisms 5
7, 57, since it is only necessary to drive and control the pinion 44 described above, the mechanism can be simplified compared to a device with a conventional structure, and the receiving plate 46 and needle 48
This has the effect of simplifying timing control.

In terms of the correspondence between the structure of this invention and the above-mentioned embodiment, the mat supply section of this invention corresponds to the mat supply device 7 of the embodiment, and the pushing section corresponds to the mat loading device 9 in the same manner. , This invention is not limited to the configuration of the above-described embodiment.
