The delivery mechanism 7 includes a moving means 20.
The front moving piece 53 moves the seedling box N on the transport conveyor means 54 forward and transfers it onto the lifting rod 46 at the upper position, and the lifting means 19 operates the hydraulic cylinder 48 to lower the lifting rod 46, As a result, the seedling box N descends from the upper position and is delivered to the distribution feeding means 3, and conversely, when the seedling box N is conveyed onto the distribution feeding means 3, the elevating rod 46 is positioned in the distribution feeding means 3. By raising from the state, the seedling box N is placed and lifted to the upper position, and the lifted seedling box N is moved rearward onto the transport conveyor means 54 by the rear movement piece 52 of the movement means 20.

The box aligning mechanism 16 and the box picking mechanism 17 are the same mechanism, only the tipping tool involved in the seedling box N is different, and if the abutment tool 23 is used as the tipping tool, the box aligning mechanism 16 for the seedling box laying machine is used. Therefore, the hook 22 serves as the box pick-up mechanism 17 for the seedling box collecting machine. That is, the support frame 4
5, a pair of guide rails 60 are projected forward above the left and right conveying means 36, a slide base 61 is suspended and supported by each of the guide rails 60, and a driving means such as a motor or a hydraulic cylinder (not shown). The mounting table 63 is supported by each of the sliding tables 61 so as to be vertically movable via the lifting cylinder 62.

The elevating cylinder 62, the swing cylinder 65, the vertical cylinder 67 and the like constitute the actuating means 24, and the driving means and the front and rear cylinder 66 and the like actuate the forward and backward moving means 25.
Is configured.

The abutment tool 23 is a plate that abuts the outer surface of the seedling box N, and the hooking tool 22 is a claw that engages the downward flange portion of the peripheral edge Na of the seedling box N from below. A plurality of these claws are provided so that they can be engaged with each other while avoiding the ribs on the back side of the downward flange of the peripheral edge Na. Both of them may be detachably attached to the tip of the rod 67a of the vertical cylinder 67, but in FIG. 11, the hook 22 is attached to the tip of the rod 67a and the hook 22 is brought into contact with the hook. Two
3 is hooked and stopped by a stopper 68 so as to be detachably attached.

In FIGS. 10 and 11, the box aligning mechanism 16 attaches the abutment tool 23 to the vertical cylinder 67, ejects the seedling box N to the ground by the front-rear transport mechanism 6, and then, through the actuating means 24 and the forward-backward moving means 25. To move the abutment tool 23 to the same height as the seedling box N in front of the front-rear transport mechanism 6, actuating the driving means or advancing the work traveling machine body A2, so that 16 side-by-side seedling boxes N are arranged.
At the same time, the rear seedling box N is brought into contact with the seedling box N laid earlier to close the front-rear gap between the two.

12 and 13, the box pick-up mechanism 1
7, a hook 22 is attached to each vertical cylinder 67, and the hook 22 is moved to approximately the same height as the seedling box N in front of the front-rear transport mechanism 6 via the actuating means 24 and the forward / backward moving means 25. While detecting the rear edge Na at the rear end of the seedling box N, each hook 22 is individually adjusted so as to correspond to the seedling box N that it picks up, and the underside of the peripheral edge Na of the seedling box N is detected. (Indicated by a chain line in FIG. 12). The cylinder 65,
The positions of the latches 22 of 66 and 67 can be finely adjusted.

After inserting the respective hooks 22 below the peripheral edge Na of the seedling box N, the respective hooks 22 are individually or simultaneously raised by the contraction operation of the vertical cylinder 67, and the peripheral edge Na is moved from the bottom. Hang and pull up. At this time, even if the root coming out of the seedling box N sticks to the ground, it can be pulled out.
After this pulling up or in the middle, the swing cylinder 65 is actuated to change the posture of the hook 22 such that the bottom surface of the hook 22 is substantially parallel to the front-rear transport means 36 (two-dot chain line in FIG. 12). As shown in FIG.
It will be parallel to 6).

Then, while the working traveling machine body A2 is moved forward, the hooking member 22 is moved to a position above the front-rear transporting means 36 by the forward-backward moving means 25, and the vertical cylinder 67 is slightly extended,
While placing the seedling box N on the front-rear transporting means 36, the latch 22 is released from the peripheral edge Na and the lifting cylinder 62, the front-rear cylinder 66, etc. are operated to prevent the seedling box N from being transported. As described above, the hook 22 is retracted above the front-rear transport means 36.

When the seedling box N is placed on the front / rear transporting means 36, as shown in FIG. 13, the front / rear transporting means 36 depends on the height or front / back position of the hook 22 with respect to the front / rear transporting means 36. Place the seedling box N so as to lean against the front end of the seedling box N (between the rear end and the center). Then, the pull-up side end of the seedling box N is lifted from the front-rear transporting means 36 at an angle E, and in this state, a large gap is formed between the hook 22 and the front-rear transporting means 36. Therefore, due to this large gap, the hook 2
2 can be easily and surely removed from the peripheral edge Na. If a part of the seedling box N is hooked on the front-rear conveying means 36, it can be conveyed by the operation of the front-rear conveying means 36. However, after moving the front and rear half or more of the seedling box N onto the front-rear transporting means 36 by the hooking device 22 and completely placing the seedling box N on the winding body 28, the hooking device 22 of the winding body 28 is moved.
