Description

[Detailed description of the device] (a) Industrial application field The present invention is a pot formed by forming a checkerboard-like recess in a seedling box,
The present invention relates to the structure of a seedling raising system in which each pot is filled with soil, sown, and covered in order.

(B) Conventional Technology The configuration of a seedling raising system has been publicly known, and for example, the technology of Japanese Utility Model Publication No. 63-12660 is publicly known.

In such a conventional technique, the protrusions formed on the surface of the driving roll are fitted into one row of pots of the seedling box to convey the seedling box by rotation of the roll, and the driving roll and the seed pressing roll for suppressing the seeds after sowing. The seed hole forming roll and the seeding machine were arranged between them.

(C) Problems to be solved by the device However, if small stones are mixed in the medium and it is caught between the pot and the protrusion of the drive roll, the drive may be stopped,
The pot may be damaged or the seeding work may be hindered, and it is necessary to cover the soil after sowing and suppression.
It was necessary to install a separate soil cover device or cover the soil separately.

(D) Means for Solving the Problems In view of such a point, the present invention is configured as follows so that it is possible to perform consistently from sowing to covering soil.

In a seedling raising machine for pot seedlings in which a certain amount of seeds are sown in the pots 6a formed in the seedling box 6, the seedling box 6 is placed on the base 1.
Soil inserting device A for filling bed soil in the traveling direction, bed soil 13 for seedling box 6
A scraper 2 that is flattened higher than the upper surface 6b, a pressing roller 3 that forms a seeding recess 13a deeper than the upper surface 6b, a seeding device B that seeds one grain at a time, and a soil cover brush 4 that fills the seeding recess 13a.
It is arranged in sequence with a pressure suppression roller 5 that presses the upper part of the seed.

(E) Operation of the device With such a structure, if the seedling box 6 is placed on the conveyor belt 7 and conveyed, a little more soil is fed out in the soiling apparatus A, and the scraper 2 is evened out. Top of box 6
The soil is formed with a certain height higher than 6b, and excess soil is removed. Then, the protrusions 3a of the pressing roller 3 cause the pots 6a and 6a.
... Seeding recesses 13a, 13a ... are formed in each
The seeds are inserted one by one from the seeding device B into the seeding recesses 13a, 13a ... And the upper surface 6b of the seedling box 6 is rotated by the rotation of the soil cover brush 4.
The soil is dropped into the sowing recesses 13a, 13a ..., and the seeds are filled and leveled. Then, the protrusions 5a, 5a of the compression roller 5
・ ・ The seeds are suppressed and the one stroke is completed.

(F) Embodiment The purpose and structure of the present invention are as described above, and the structure of the embodiment shown in the accompanying drawings will be described.

Fig. 1 is a perspective view of a seedling raising machine for pot seedlings of the present invention, Fig. 2 is a side sectional view showing the same working state, and Fig. 3 is a pot sectional view.

The seedling raising machine for pot seedlings is arranged on the base 1 in this order from the left: a soil putting device A, a scraper 2, a pressing roller 3, a seeding device B, a soil covering brush 4, and a pressure suppressing roller 5, and a seedling box 6 is provided on the base 1. A transport belt 7 for transporting the
A motor box 9 for driving the conveyor belt 7 is arranged on one side, and a control box 10 for controlling driving speed, ON, OFF, etc. is arranged beside it.

The seedling box 6 has a truncated cone-shaped recess to form a pot 6a.
.. and the pots 6a, 6a ... Are arranged in a grid pattern.

The soil feeding device A has a feeding belt 12 arranged below the hopper 11 in parallel with the conveyor belt 7. The feeding belt 12 is driven only when the seedling box 6 is passing to drop the soil for a predetermined amount, and the seedling box is fed. 6 pots 6a, 6a ... are filled with soil to make floor soil,
The soil is set higher than the upper surface of the seedling box 6. still,
The feeding belt 12 is driven by a motor, detects the seedling box 6 by a sensor, and is configured to be driven only when the seedling box is passing under the soil filling device A. However, the rotation of the conveyor belt 7 (the inner side of which is a toothed belt) is transmitted to the driven sprocket, and the feeding belt 12 is driven from the driven shaft that fixes the sprocket through a clutch that switches depending on the presence or absence of a seedling box. It is also possible to do so.

The scraper 2 is fixed to the support frames 14 and 14 installed upright on the base 1 so as to be adjustable in the vertical direction in parallel with the conveyor belt 7, and is disposed obliquely with respect to the traveling direction so that the excess soil is dropped sideways. I have to. Then, as shown in FIG. 3, the scraper 2 is arranged so that the soil 13 is piled up higher than the upper surface 6b of the seedling box 6 by a.

The pressing roller 3 has a truncated cone-shaped projection 3a.
Are projected radially in several rows according to the widthwise pitch of the pot 6a, and the power is transmitted from the conveyor belt 7 (or a chain may be wound parallel to the side of the base) to the driven shaft via a sprocket, It is driven by a gear that is fixed to the driven shaft.
Then, by the drive, the pressing roller 3 is rotated in synchronization with the conveyor belt 7, the protrusion 3a penetrates into the floor soil 13 at the center of the pot 6a, and as shown in FIG. The depth c is made to plunge, and the width c of the tip is made larger than the diameter d of the seed S to form the sowing recess 13a. It is desirable that the pot 6a and the projection 3a have similar shapes, but the shape of the projection 3a should be pointed so as to form a conical seeding recess 13a 'as shown in FIG. It is also possible to replace the pressing roller 3 according to the size and the number of rows of seeds and pots 6a, and the sowing depth is also adjusted.

The seeding device B is provided with a feeding roll 16 below the hopper 15, and the feeding recesses 16a, 16a, ... Are provided on the roll surface of the feeding roll 16.
Are provided in accordance with the pitch of the pots 6a, 6a ... And the feeding roll 16 is rotated in accordance with the conveyance of the seedling box 6 to insert seeds into the feeding recesses 16a, 16a. It is conveyed downward and seeded in pots 6a, 6a ... one by one.

The soil covering brush 4 is rotated in the opposite direction to the advancing direction, and the lower end of the soil covering brush 4 is fixed at a height in contact with the upper surface of the seedling box.
The thickness a of the upper soil 13 is eliminated, and the seeding recess 13a is formed.
・ 13a ... is filled and leveled. However, a scraper can be used instead of the brush.

The compression roller 5 is provided with hemispherical projections 5a, 5a ... on the surface of the cylinder in accordance with the pitch of the pots 6a, 6a. Is pressed to suppress the pressure.

(G) Effect of the invention With the above-mentioned configuration, the following effects of the invention are obtained.

Firstly, since the floor soil is leveled higher than the upper surface of the seedling box by the scraper and the seeding recess is formed by the pressing roller, stones or the like are caught between the protrusion of the pressing roller and the seedling box. Without this, the friction between the seedling box and the pressure roller was eliminated, and the transportation became smooth.

Secondly, since the soil is covered with the soil-covering brush after seeding in the seeding recess, it is not necessary to dispose the soil-filling device in the process after seeding, and the soil-covering and the leveling can be simultaneously performed with a simple structure. It became like this.
