Description

[Detailed description of the invention] This invention relates to an improvement of a seedling raising device for raising seedlings in piles.

The current state of seedling raising devices will be explained based on FIGS. 1 to 4. A frame 4 on which seedling boxes 3 are placed is provided at the bottom of the seedling nursery 2a installed on the ground 1, and four seedling boxes 3 are usually placed along the short sides of the frame 4 in the front-rear direction. In this way, they are arranged to form unit rows A, and the unit rows A are usually arranged in two to six rows in the left and right direction to form the underframe 4. Then, front and rear supports 5a, 6a are erected at the four corners of each unit row A, A,
A ceiling frame 8 was installed on the supports 5a, 6a.
Therefore, the seedling growing box 3 is usually taken in and out from between the front supports 5a, 5a. However, the underframe 4 has a certain height B because the heater 9 is disposed therein. Therefore, when loading and unloading the seedling box 3, raising and lowering is involved, which is extremely troublesome, and the front support 5a becomes a hindrance to carrying it. This idea was made to solve these problems.

An embodiment of this invention will be described based on the drawings.

The seedling raising device 2 according to this invention includes a horizontal vertical member 10 extending in the front-rear direction and a horizontal horizontal member 11 extending in the left-right direction with a length that is an integral multiple of twice or more the long side of the seedling raising box 3.
and an underframe 4 having a rectangular parallelepiped shape as a whole.
At the same time, a heater 9 is arranged inside the underframe 4, and is kept at a distance equal to or longer than the length of the short side of the seedling box 3 from both front and rear edges of the upper surface of the underframe 4, and from both the left and right sides of the upper surface of the underframe 4. At least one support 7 is erected at an arbitrary location in an area with a distance equal to or longer than the length of the long side of the seedling box 3 from the edge, and the shadow projected onto the top surface of the underframe 4 almost matches the top surface of the underframe 4. A ceiling frame 8 is installed extending over the four sides of the support 7, and the four edges of the ceiling frame 8 and the underframe 4
An arbitrary number of easily attachable and detachable vertical bars 12 are arranged between the four edges of the underframe 4 and the ceiling frame 8, and a cover 13 placed on the ceiling frame 8 extends downward along the outside of the vertical bars 12. It is configured such that a large number of seedling growing boxes 3 can be stored between it and the frame 8.

The seedling raising device according to this invention has excellent workability because there are no supports that get in the way when carrying the unit rows at both left and right ends and the front and rear seedling raising boxes.

The pillars of the present invention are significantly stronger than conventional pillars, and are firmly attached to the underframe, and the ceiling is also firmly attached to the pillars.

In addition, the cover 1 can be attached using a vertical rod that is attached after loading the seedling box and removed before lowering the seedling box.
3 and the seedling raising box 3 can be sufficiently secured for convection.
