Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for filling floor soil in a tray used for raising seedlings of agricultural products such as vegetables.

[0002]

2. Description of the Related Art Generally, when producing agricultural products such as vegetables, a method is used in which seeds are sown on a bed soil pre-filled in trays to grow seedlings, and the seedlings are transplanted to rice fields or fields. Has been adopted.

In order to fill the empty tray with the floor soil, a step of filling the tray with the floor soil, a step of compacting the filled floor soil, and a step of leveling the surface of the hardened floor soil are performed. And removing extra bed soil from the tray.

Therefore, conventionally, a hopper containing floor soil along a path for transporting the tray at an appropriate speed, and a belt conveyor which feeds out the floor soil in the hopper by an appropriate amount and drops to a tray below. A hardening means such as a hardening roller for pressing the floor soil filled in the tray and a smoothing means such as a brush roller for flattening the surface of the floor soil are sequentially arranged.

[0005]

However, as described above,
Arranging the belt conveyor, the hardening means, and the leveling means sequentially along the transfer path of the tray would result in a considerable lengthening of the entire length, resulting in an increase in the size of the apparatus. was there.

SUMMARY OF THE INVENTION An object of the present invention is to provide a filling apparatus which solves this problem and an increase in the size of the apparatus.

[0007]

In order to achieve the above technical object, the present invention provides a method comprising the steps of: "a hopper containing floor soil, and an appropriate amount of floor soil in the hopper are fed out above a path for transferring trays. A belt conveyor that falls on the lower tray, a hardening unit that solidifies the floor soil filled in the tray, and a floor soil filling device that can be provided with a smoothing unit that smoothes the surface of the floor soil, wherein the belt conveyor includes: The floor soil is transported in the direction opposite to the tray transport direction and falls, and the consolidating means and the leveling means are disposed below the belt conveyor. "

[0008]

As described above, the belt conveyor is
By transferring the floor soil in a direction opposite to the tray transfer direction and dropping it, and disposing the fixing means and the leveling means below the belt conveyor, the belt conveyor and the fixing means And the leveling means can be overlapped along the transfer path of the tray, in other words, the space below the belt coiler can be used for arranging the hardening means and the leveling means. Can be reduced by this overlap.

Therefore, according to the present invention, there is an effect that the device for filling the floor with the tray can be significantly reduced in size and weight.

[0010] In particular, by providing the belt conveyor with a scraper for the inner surface of the belt, it is possible to prevent the soil from adhering to the inner surface of the belt.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to FIGS. In this figure, reference numeral 1 denotes a pair of right and left body frames, and two rails 2 extending parallel to each other and extending in the horizontal direction are provided between the two body frames 1. Endless chains 3 wound around sprockets 4 and 5 at the ends of the frame 1 are disposed so as to extend in parallel with both rails 2. Further, the endless chains 3 are provided with a flat surface for a seedling raising tray 8 described later. A U-shaped contact piece 7 is provided so as to protrude from the upper surfaces of both rails 2.

Reference numeral 8 denotes a seedling raising tray formed by arranging a plurality of pot portions 8a in the vertical and horizontal directions. The tray 8 is placed on the under tray 9.

Above one end of the body frame 1,
The stock unit 1 of the tray 8 placed on the under tray 9
0, and the tray 8 in the stock unit 10 is dropped on the under tray 9 so that the tray 8 is placed on the upper surfaces of the two rails 2.
With the rotation of the endless chain 3, the rail 2 is transported at an appropriate speed in the direction of arrow A while sliding on the upper surface of the rail 2.

A hopper 11 containing floor soil is disposed below the body frame 1, and an endless belt 13 is horizontally wound around a pair of left and right pulleys 14 and 15 below the hopper 11. Belt conveyor 12
Is provided on the belt conveyor 12 so as to close the opening at the lower end of the hopper 11, and by the rotation of the belt conveyor 12, the floor soil in the hopper 11 is fed out by an appropriate amount and falls down from one end thereof. The configuration is as follows.

In this case, the belt conveyor 1
2, the direction of transfer of the floor soil is opposite to the direction of transfer of the tray 8 as shown by the arrow B, and the left and right ends of the belt conveyor 12 are located on the front side with respect to the transfer direction of the tray 8. A lower roller of the belt conveyor 12 and a compacting roller 16 pressed against a top surface of the tray 8 by a spring (not shown) while rotating in the direction of the arrow; And a brush roller 17 that contacts the upper surface of the tray 8 while rotating.

The belt conveyor 12 has a scraper 21 that contacts the inner surface of the endless belt 13.
Is provided to prevent the soil from adhering to the inner surface of the endless belt 13. The scraper 21 is formed in a mountain shape with respect to the direction before the movement of the endless belt 13 in a plan view, or is configured to be inclined with respect to the movement direction.

In this configuration, when the tray 8 in the stock section 10 is supplied onto both rails 2, the tray 8 is moved by the endless chain 3 in the direction of arrow A at a suitable speed below the hopper 11 in front of it. During the transfer, the floor soil in the hopper 11 is dropped on the tray 8 from the belt conveyor 12 below the hopper 11 by the guide of the chute plate 18, and is transferred to the respective pot portions 8 a. The bed soil is filled.

The upper surface of the tray 8 is pressed while the fixing roller 16 is rotating, thereby squeezing the floor soil in each pot portion 8a. Next, the brush roller 17 is mounted on the upper surface of the tray 8. By contacting while rotating, leveling of the surface of the floor soil and removal of excess floor soil are performed, and after watering from the nozzle 20 is performed, the water is sent to the next sowing process and the like. is there.

According to the present invention, as described above, the hopper 11
The belt conveyor 12 at the lower part of the
The belt conveyor 12, the compaction roller 16, and the compaction roller 16 and the brush roller 17 are disposed below the belt conveyer 12 by being transported in a direction opposite to the transport direction of the belt conveyer. Brush roller 17
Can be overlapped along the transfer path of the tray 8.

In the above embodiment, the fixing roller 16 is used as the fixing means, and the brush roller 17 is used as the leveling means.
However, it is needless to say that other configurations may be adopted, such as using a vertically moving type as the hardening means or a scraper type as the leveling means. In the hopper 11, a rotary blade roller 19 for preventing clogging of the floor soil is provided.
