Abstract

PURPOSE: To provide a device for packing bed soil by putting a pot sheet comprising plural trapezoidal pots in a seedling box, packing bed soil supplied to the pot sheet from germination holes on the top to a hollow part by vibration of the seedling box and preventing the packed bed soil from separating into large and small particles by the vibration. CONSTITUTION: This device for packing bed soil is equipped with a conveyor 4 for transporting a seedling box 2 charged with a pot sheet obtained by arranging trapezoidal pots having germination holes on the top in front and rear and right and left directions and integrating them, a bed soil feeding device 7 for supplying bed soil onto the pot sheet of the seedling box 2 being sent by the conveyor 4 and plural oscillators 21 to apply vibration in the vertical direction to the seedling box 2 so as to reduce vibration acceleration according to the separation of the seedling box 2 from the supply position of the bed soil.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to fill a pot in a seedling box with bed soil in a seeding device or the like of a seedling raising facility.

[0002]

2. Description of the Related Art In order to separate and grow seedlings one by one,
Trapezoidal pots are arranged side by side in the front, rear, left and right to integrally form a pot sheet, and floor soil is put in each pot, and seeding is performed in this. Then, in order to fill the soil in the pot, put the pot sheet inside out and place it on a board, fill the soil in the empty part of the pot from the wide side, cover it with a seedling box and invert it. The technique of removing the board was used.

In the above method, it is necessary to invert the seedling box and other man-hours. To improve this, the bed soil is supplied to the seedling box from above the pot sheet, and the seedling box is vertically vibrated. Attempts have been made to fill bed soil from the germination holes on the top surface into the cavity of each pot.

[0004]

With respect to the vibration applied to the seedling box, if a large acceleration (amplitude, frequency) is used,
In a relatively short period of time, the bed soil moves from the germination holes into the cavity below it and fills it, but due to the vibration, small particles of the bed soil sink to the bottom and large particles float to the top. The seedlings did not grow well because they had risen and separated. In addition, if the one with a small acceleration is used, there is a drawback that it takes a long time to fill the floor soil, the equipment becomes large, and the efficiency decreases.

[0005]

In order to solve the above-mentioned problems, according to the present invention, trapezoidal pots 1b having germination holes 1a on the upper surface are integrally provided side by side in the front, rear, left and right to form a pot sheet 1. The seedling box 2 is provided with a conveyor 4 for transferring the seedling box 2 containing the pot sheet 1, and a floor soil supply device 7 for supplying the floor soil onto the pot sheet 1 of the seedling box 2 sent by the conveyor 4. Multiple oscillators 2 that give vertical vibrations
The reference numeral 1 represents a bed soil filling device provided so that the vibration acceleration becomes smaller as the seedling box 2 moves away from the bed soil supply position.

[0006]

Since the present invention is configured as described above, when the seedling box 2 containing the pot sheet 1 is fed by the conveyor 4, the floor soil is supplied onto the pot sheet 1 by the floor soil supplying device 7. To be done. Next, the seedling box 2 is vertically vibrated by the oscillator 21, and the vibration causes the bed soil on the pot sheet 1 to flow through the germination holes 1a into the cavity of the pot 1b and be filled. It

[0007]

[Effects] According to the present invention, the seedling box 2 containing the pot sheet 1 is fed by the conveyor 4 and then the soil is supplied onto the pot sheet 1, and subsequently, the seedling box 2 is vibrated in the vertical direction. The bed soil is filled into the cavity of the pot 1b through the germination hole 1a, and the vibration has a large vibration acceleration immediately after the bed soil is supplied, and becomes smaller as the distance from this position increases, The pot soil is filled in the pot 1b in a relatively short time, and small and large particles are separated from the filled pot soil, which is advantageous in growing crops.

Embodiments of the present invention will be described below. FIG.
Like a trapezoidal pot 1b with a germination hole 1a on the top
The pot seat 1
Has become. The pot sheet 1 is integrally formed of pulp material or the like. Two pot sheets 1 and 1 are arranged side by side in a thin seedling box 2 having an inner size of about 30 cm × 60 cm.

As shown in FIG. 2, an inclined conveyor 3, a conveyor 4 and a second conveyor 5 are provided in this order from right to left. The seedling box feeder 6 is provided to the right of the inclined conveyor 3, and the seedling boxes 2, 2, ... Are continuously supplied onto the inclined conveyor 3. Bed soil supply device 7 is conveyor 4
It is provided on the irrigation device 8, irrigation device 8, spot seeding device 9, and seeding device 1
0, the soil cover device 11 and the second irrigation device 12 are provided on the second conveyor 5 in this order from the right. And
The spot seeding device 9 and the dispersal device 10 are selectively used as needed. That is, when the pot sheet 1 is put in the seedling box 2 and the seeds are sowed in the respective pots 1b, 1b ..., The operation of the seeding device 10 is stopped and the seeding device 9 is used to put the pot sheet 1 in the seedling box 2. When the bed soil is directly put in without putting it and seeds are sowed on it to make mat seedlings for paddy rice, the operation of the point sowing device 9 is stopped and the sowing device 1
0 is used.

The floor soil supplying device 7 and the conveyor 4 are constructed as shown in FIG. That is, in the floor soil supply device 7, the flat belt 15 is wound around the pair of left and right rollers 13 and 14 and is rotated clockwise. A hopper 16 containing soil is provided on it, and this soil is fed from the gate 17 to the flat belt 1.
By rotating 5 times, the seedling box 2 can be taken out with the same thickness as the depth of the seedling box 2. The flat belt 20 is wound around the pair of left and right rollers 18 and 19 to form the conveyor 4,
