Description of the Related Art In seedling raising work for rice and vegetables, seedling boxes are sprouting after being germinated by arranging them in units of several hundreds to several thousand in a greenhouse for greening and / or hardening treatment. Techniques for mechanization have been developed in order to perform efficiently in the company. As a technique for laying and collecting seedling boxes, Japanese Patent Laid-Open No. 7-1
There is a seedling box collector / distributor disclosed in Japanese Patent Publication No. 07817. This technology uses a traveling device to move the machine forward and backward, a vehicle-mounted part on which the nursery box carrier is placed, the transfer of the nursery box from the ground to the machine and the transfer of the nursery box from the machine to the ground. Automatically transporting seedling boxes, loading the seedling boxes on the machine into the seedling box on the in-vehicle mount, and lowering the seedling boxes loaded in the seedling box on the on-board mount onto the machine A seedling box loading / unloading device that can selectively perform work is provided.

高い位置に配置できるようにするためである。The rear upper end of the support arm 127 has a rotating shaft 131.
The rotary shaft 131 is rotatably supported by a moving frame 132 via bearings, and the moving frame 132 is mounted on the left and right support rails 126 fixed to the base frame 31B of the machine body 31 via wheels. It is supported so that it can move back and forth. The support arm 127 can be formed of a linear member, but is formed of a plate member having a rear portion standing up and having a substantially L shape in a side view.
This prevents the front-rear conveying means 18 from interfering with the rear part of the front-rear conveying means 18 when the supporting arm 127 rotates downward, so that the front-rear conveying means 1 does not interfere with the machine body 31 when rotating upward.
This is because the vertical / horizontal transport mechanism 5 can be arranged at a sufficiently high position so that the robot 8 can be lifted sufficiently.
