DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention is provided with a seeding platform equipped with, for example, a soil-filling machine, a seeding machine, a soil-covering machine, etc., and a floor hopper is provided above the soil-filling machine; The present invention relates to a seeding device in which a soil-covering hopper is installed above each seedling table, seedling growing boxes are continuously supplied to the seeding platform, and seeding work is automatically and continuously performed.

``Prior art'' Conventionally, as shown in Japanese Utility Model Application No. 51-146229, a soil container, a seeding machine, etc. are mounted on a seeding stand, and a conveyor is used to carry soil into a bed soil hopper installed above the soil container. There was a technology to supply the floor through the.

``Problems to be Solved by the Invention'' The above-mentioned prior art had a large-capacity hopper installed above the seeding table, but since this hopper was connected to the seeding table, the structure of the seeding table could be simplified. This is not easy to do, and there are problems in that expansion of the capacity of the hopper is restricted by the support structure and the like.

However, the present invention provides a sowing device in which a seeding table is disposed on the first floor of the working room and soil is supplied from the basement of the working room to the seeding table. A large-capacity hopper for soil will be installed from the first floor to the second floor, and a work room 1 will be installed.

In addition, if the amount of soil covered in the soil covering tank (32) is insufficient and this is alarmed by the lower level meter (43), only the second two-prong gunbake 5) is switched and each damper (14] (151 is The feed end of the third conveyor (12) is connected to the feed start end of the sixth conveyor (31),
The sorted material carried out by the third conveyor (12) is transferred to the sixth conveyor (31) via each damper (141 (15)) and carried into the soil covering tank (32).

Furthermore, when the fertilizer and pesticides in the chemical tank (17) are insufficient, only the most forked damper (14) is operated to switch the feeding end of the third conveyor (12) to the chemical tank (17).
7), put the fertilizer and pesticides in the potting soil type (2) into the chemical input hopper (13), and transfer the fertilizers and pesticides to the third tank.
The chemical is transported by a conveyor (12) via a damper (14) to a chemical tank (17), and the soil is transported into a chemical tank (17) by a conveyor (12).
6) and the culture medium (for sorting) taken out from the chemical tank (17), fertilizer, etc. are mixed in a set ratio with a ribbon mixer (20) to make bed soil, and the horizontal damper (21) is opened and closed to mix the culture medium (on sorting) and fertilizer, etc. 20) is dropped onto the hopper (22), and the bed soil in the hopper (22) is transferred to the rotary dresser (25) by the fourth and fifth conveyors (23) (241).
), the finished floor by the dresser (25) is stored in an above-floor tank (26), and the finished floor is stored in an above-floor tank (26).
The soil is supplied from the tank (32) to the soil covering machine (30) on the floor, and the seedling box (al) is continuously moved by driving each part of the seeding table (27). The seeding work is carried out continuously.

In addition, as mentioned above, the seedling raising box after sowing is mounted on the seedling raising cart, and the budding chamber (4) and the first and second greening chambers (51 (
61 to perform seedling raising work.

In addition, during the seeding work, when the bed is placed in the seedling raising box (at) that is moved downward by the soil filling machine (28) and the bed soil leveling work is performed to level the bed to a uniform thickness, the top of the bed is leveled. The surplus bed that leaked from the seedling box (a) during the flat work falls below the soil container rock [28], and falls to the feed start end of the seventh conveyor (33) via the hopper (35). 7 and 8 conveyors (33) (341) to the floor hopper (36), and the surplus floor is conveyed to the rotary dresser (2) by the fifth conveyor (24).
5) and then returned to the floor tank (26).

"Effects of the Invention" As is clear from the above embodiments, the present invention
A seeding table (27) will be installed on the first floor, and a work room (3
) In the seeding device that supplies soil from the basement to the seeding table (27), the soil is placed above the seeding table (27) from the first floor of the work room (3)
A large-capacity hopper (26) for soil-filling is installed across the floors, and the end side of the soil-filling conveyor (24) whose starting end is lower than the first floor of the workroom (3) is the workroom (3).
