Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention uses a long seedling mat that is longer than a conventional seedling mat and has a length of about 6 meters as a seedling for rice transplanters. The present invention relates to the structure of a long seedling raising tray for growing mats.

[0002]

2. Description of the Related Art A conventional seedling mat for rice transplanters has a rectangular seedling mat having a width of 28 cm and a length of about 60 cm. However, in the rice transplanters etc.
With the conventional seedling mats, the seedlings quickly disappeared, and the operator had to turn around and splice the spare seedling mat onto the seedling mounting table, which frequently caused operator fatigue. Of. Also, in the case of conventional seedling mats, the number of sheets to be transported as spare seedlings increases,
Management and transportation were troublesome tasks.

[0003]

DISCLOSURE OF THE INVENTION The present invention solves the problem that the seedling mat of the normal length has a large number of splicing joints. That is, as a long seedling mat, the length is 6

As described above, the inner tray 42 is placed inside the outer tray 48, the seedbed sheet 4 is placed inside the inner tray 42, and the seeds S are sown on the upper surface of the seedbed sheet 4. The long seedling raising tray 1 is composed of an inner tray 42 and an outer tray 48, and a nutrient solution for hydroponic culture flows inside the outer tray 48 and a nutrient solution also flows inside the inner tray 42. . According to the present invention, as shown in FIGS. 5 and 6, a protrusion 42a is provided on the lower surface of the inner tray 42 to form a washing plate-like uneven groove in the lateral direction. Since the nutrient solution flows in this longitudinal direction, when the seeds S flow in this direction, the seeds S accumulate around the downstream nutrient solution discharge port 46 or the seeds S flow out toward the outer tray 48. That is the problem.

According to the present invention, in order to solve such a problem, the protrusion 42a is arranged in the lateral direction and the seedbed sheet 4 is placed on the protrusion 42a. The seedbed sheet 4 also has the protrusion 42a.

In the configuration shown in FIG. 7, the inner tray 4
Rubber fitting grooves 51 are provided in the left and right corners of 2, and both ends of the seedbed sheet 4 are extended in the rubber fitting grooves 51, and the sheet tension rubber 52 is placed on the rubber sheet tension rubber 52. A configuration is disclosed in which the seedbed sheet 4 is fitted into the fitting groove 51 to prevent the seedbed sheet 4 from moving. This removes wrinkles from the nursery sheet 4 and improves the seeding accuracy. Also,
The operation of laying the nursery sheet 4 and removing wrinkles can be easily performed, and the work cost can be reduced.

In FIG. 8, the portion dividing the inside of the outer tray 48 into the inner tray 42 is constructed by partitioning the partition plates 43 and 44 so as to be removable. When the seed hopper 43 is removed, it can be used as a tray for cultivating horticultural crops other than rice seedlings. In addition, the nursery sheet 4 is also the external tray 4
When laying 4 sheets of the size of 8 as one seedbed sheet 4 with perforations and attaching the partition plates 43 and 44,
By cutting the perforations, it is possible to divide into four nursery sheets 4. As a result, the long seedling raising tray 1 can be provided with versatility, and by laying four sheets with one perforation, the cost of placing the nursery sheet 4 can be reduced.

In FIGS. 9 and 10, after raising the seedlings,
The mechanism for cleaning the outer tray 48 and the inner tray 42 has been described. Since the outer tray 48 is long and wide, the corners and side surfaces cannot be sufficiently cleaned. In the main cleaning mechanism, by combining the brush 56 and the nozzle 57,
The outer tray 48 and the inner tray 42 are configured to be washed. The brush 56 rotates and the outer tray 48 and the inner tray 42 transported by the transport device pass below the portion where the high pressure water is discharged from the nozzle 57. The brush 5
While rotating 6, the outer tray 48 and the inner tray 42
Insert into the long seedling tray 1 composed of
It is washed.

In FIGS. 11 and 12, the inner tray 4
A special construction of the nursery sheet 4 fitted inside the 2 is disclosed. That is, the center in the lateral direction has a normal height, but the corners near the left and right side plates are thin seedbed sheets 4b. The internal tray 42 is configured in this manner.
This is because the seed S collides and reflects at a portion near the side plate of, so that the seeding density of this portion is reduced. In order to avoid this reduction in seeding density, the seedbed sheet 4 in the side plate portion is thinned so that the seeding density is the same as that in the central portion.

In FIG. 13, when the nursery sheet 4 is laid inside the inner tray 42, it is difficult to lay it uniformly in a wrinkle-free state. A configuration is disclosed in which the pedestal sheet 4 is laid around the periphery and the underlayment base 55 and the seedbed sheet 4 are integrally fitted into the inner tray 42 to facilitate the laying of the seedbed sheet 4. With this configuration, the nursery sheet 4 is less likely to be wrinkled, and wrinkles do not cause uneven sowing when sowing. The base 55 is made of a material that dissolves when a nutrient solution is added.

[0027]

As described above, the present invention has the following advantages. Since it is configured as in claim 1, a seedbed sheet 4 is laid as a floor soil material inside the long seedling raising tray 1, seeded on the seedbed sheet 4, and seeding for a long seedling mat for raising seedlings by hydroponic cultivation. In the machine, since the projections in the direction orthogonal to the flowing direction of the nutrient solution for hydroponic cultivation are provided on the floor surface of the long-sized seedling tray 1, the seedbed sheet 4 placed on the internal tray 42 also has a washing plate. -Shaped uneven corrugations are formed, and the seeds S are held in these portions, so that the seedling density on the surface of the nursery sheet 4 does not move toward the nutrient solution discharge port 46 due to the flow of the nutrient solution. It changed or disappeared due to the flow of.

Since the seed hopper 43 is removed, it can be used as a tray for cultivation of horticultural crops other than rice seedlings.
In addition, the nursery sheet 4 is also laid by arranging four sheets of the size of the external tray 48 as one nursery sheet 4 with perforations.
When the partition plates 43 and 44 are attached, the perforation can be cut to divide it into four nursery sheet sheets 4. As a result, the long seedling raising tray 1 can be provided with versatility, and by laying four sheets with one perforation, the cost of placing the nursery sheet 4 can be reduced.

According to the third aspect of the invention, the wrinkles of the nursery sheet 4 are removed and the seeding accuracy is improved. Also,
The operation of laying the nursery sheet 4 and removing wrinkles can be easily performed, and the work cost can be reduced.
