Abstract

PURPOSE:To prevent the escape of hot air from a raising seedling chamber in spite of the use of a drain ditch connected to the outside of the chamber and having decreased capacity by connecting a drain pipe to a drain ditch covered with a lid having a ventilation hole on the upper surface and providing a water-reservoir shielding mechanism at the inlet-side of the drain pipe in a raising seedling chamber. CONSTITUTION:Excess irrigation water dripped on the floor surface 1 in a raising seedling chamber D is introduced into a drain ditch 2 and discharged from the chamber through a drain pipe 4. Hot air blown from a room-heater is passed through the ditch 2 and ejected through the ventilation hole 3a of a lid 3 into the raising seedling chamber D to heat the chamber. The escape of hot air from the ditch 2 through the drain pipe 4 is prevented by the presence of a water-reservoir shielding mechanism 5 and the intrusion of cold outer air into the chamber through the drain pipe 4 is also prevented. The flow of air can be prevented in spite of the use of a drain ditch connected to the outside of the chamber and having decreased capacity because water is always retained in a water-reservoir hole 6 by a shielding plate 7 and the inlet of the drain pipe 4 is maintained in a state sealed with the retained water.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a seedling room for growing paddy rice seedlings and vegetable seedlings.

Prior Art Patent Publication 1987-857 As seen in the medical examination, there was a seedling nursery room where the drainage ditch was used as a hot air passage.

Problems that the invention aims to solve In the conventional system, a drainage ditch is simply provided in the seedling nursery room, and the water overflowing from submerging during seedling raising is collected in the drainage ditch.
Drainage ditches had to be wide and deep to keep water constantly collected. That is, if this drain was connected to the outdoors, hot air would escape and the heating effect would be reduced, so constant communication with the outdoors could not be achieved.

11. Means for Solving the Problems In order to solve the above-mentioned problems, the present invention has the bottom surface of the seedling growing chamber hardened with concrete or the like so that the seedling raising cart can easily roll around.11. At the same time, a drainage groove 2 is suitably formed on this floor surface 1, and a lid 3 in which a ventilation hole 3a is formed is provided on the upper surface of this groove 2. A drain pipe 4 having a drain outlet outside the seedling nursery room is connected to 'dI#2 of the nursery room, and a water puddle shield is installed on the entrance side of the drain pipe 4 in the nursery room to prevent hot air from escaping to the drain pipe side. This is a seedling growing room made up of Mechanism 5.

Effects and Effects of the Invention According to this invention, the capacity (depth or width) of the drainage ditch provided on the floor of the room is reduced so that no or only a small amount of water accumulates at all times. Despite the structure, the hot air can be prevented from escaping outdoors by the water puddle shielding mechanism, making it easy to create a drainage ditch, and moreover, a one-minute heating effect can be expected.

Embodiment One embodiment of this invention will be described in detail based on one drawing.
A nursery F'Ili room that can be accessed in the seedling nursery facility shown in the diagram.
] is a work room A where the indoor sowing process is carried out, and a germination room where the seedling boxes with oval seedlings are piled up and placed on a germination table, heated in a steam bath, and germinated. B and this germination chamber are taken out and the germinated growth boxes are stacked on shelves at predetermined intervals and transferred to a greening cart for greening. It is provided. This seedling-growing room D (also called a greening room) is surrounded by translucent equipment to allow ventilation.

This invention relates to this seedling growing room, and has no particular relation to the aforementioned work room A, germination room B, or stacking hoop room C.

Therefore, in detail about the seedling nursery room, 1 is the floor surface,
It is hardened with concrete, and drain holes are drilled into the floor. This groove 2 includes a horizontal groove 2a provided near the loading room C, a vertical groove 2b communicating with the horizontal groove 2a on the side of the cultivation area,
2b... It's empty.

A ventilation hole 3 through which air flows is provided on the upper surface of the winding groove 2.
A groove 3 with a hole a is provided. Further, the floor surface 1 has a gentle slope toward the groove 2, and water is sprinkled onto the floor surface 1 from the ventilation hole 3 or the gap formed between the edge of the groove 2 and the lid 3. is configured such that it flows into the groove 2.

4 is a drain pipe, and a water puddle shielding mechanism 5 is provided on the terminal end side of the groove 2.
It is connected to the Tekitora drainage canal outside the nursery school via the .

The water puddle shielding mechanism 5 is located at a communication portion between the groove 2 and the drain pipe 4, and in one embodiment, a water puddle hole 6 is provided with a deep end side of the groove 2, and the water is drained into the water puddle hole 6. The proximal end of the pipe 4 is connected to a position higher than the bottom of the hole 6, and the water in the water collecting hole 6 is connected to the entrance of the drain pipe 4 [j] from the part lower than the lower end of the entrance of the drain pipe 4. A weir plate 7 is provided so that the water flows into the water. That is, the warm air in the seedling growing room is prevented from being exhausted outside through the drain pipe 4 due to accumulated water. In addition, as shown in Figure 5, the middle of the drain pipe 4 is
It may also be shaped like a letter, in which case the weir plate can be omitted.

Reference numeral 8 denotes a warmer M, which is installed in the stacking chamber C, and whose hot air discharge pipe is communicated with one end of the horizontal groove 2a.

The structure is such that hot air flows through the groove 2 and blows out from the ventilation hole 3a of the bush 3.

The rail 9 that guides the rolling IJJ of the green compound IJtd shown in FIGS. 6 and 7 in the direction of the groove 2b is located at 111 of the vertical groove 2b.
It is on the ii side and is attached to the floor surface 1 with the Rikomi Pol 1-,
This is an embodiment in which a water passage path 9a is provided by cutting out a local part of the rail 9, and as shown in FIG. It may be configured so that it can flow into the

To explain the operation of the upper part, the 8 sowing machines A placed in the work room A are used to grow! 7 boxes of sown seeds are stacked and placed on a germination trolley, transported to germination room B heated in a steam bath, left to germinate for 2 to 3 days, and then placed in stacking hoko room C. Then, using the transloading device Ra, the greening cart d is loaded onto a shelf at a predetermined interval. The seedlings are then carried into the nursery room D (also called a greening room) for greening.

Then, the greening carts d are arranged in rows in the direction along the vertical groove 2b and arranged at predetermined intervals in the horizontal rows.

The plants are then exposed to sunlight for one night, allowing them to grow and become green. At this time, the lake water system Me is allowed to pass between the greening carts d, d, .

Excess water during irrigation flows down to the F1S natural floor 1 and tries to collect on the floor, but since this floor 1 is provided with a groove 2, the spilled water flows into the groove 2 and drains into the drain pipe 4. Water is drained through the seedling nursery room.

On the other hand, hot air from the heater 8 passes through the groove 2 and blows out into the room from the ventilation hole 3a of the lid 3. Ili Heating the room. However, the warm air flowing in the groove 2 is prevented from escaping outdoors through the drain pipe 4 by the water puddle shielding mechanism 5, and the cold air from outside is prevented from flowing into the seedling nursery room through the drain pipe 4. There is no.

That is, water is always stored in the water storage hole 6 by the weir plate 7, and the entrance of the drain pipe 4 is kept in a cold state by the stored water, thereby preventing air circulation.
