Description

DETAILED DESCRIPTION OF THE INVENTION (A) Industrial application field The present invention inserts a seedling pot in which a plurality of pots of a fixed shape are juxtaposed in a seedling raising box, and puts a certain amount of soil and seeds into the seedling pot. The present invention relates to a seeding plant for growing vegetable plug seedlings having the same seedling mass as pots attached to each seedling.

(B) Conventional technology As a conventional sowing plant, it is publicly known to disperse seed rice in a seedling box in order to construct a seedling mat for a rice transplanter.

However, there was no sowing apparatus for plug seedlings for vegetables such as spinach, radish and carrot.

(C) Problems to be Solved by the Invention In a sowing plant for growing plug seedlings for vegetables, unlike a sowing plant for growing seedling mats for rice transplanters, a certain amount of seeds is set in a small pot. Of the land,
Since a plug seedling with the seedling soil mass attached to the root portion of the seedling is made, the seedling soil mass is difficult to separate from the seedling root, has sufficient adhesiveness, and is necessary for growing to a certain size. It is necessary to provide sufficient nutrients and, unlike the soil of rice seedling mats, it is necessary to use a soil in which two or more types of soil are mixed.

The soil is a soil like peat moss and vermiculai, and both are soils that are hardly humidified to the inside only by watering from above.

Conventionally, the seedling box was filled with soil and then humidified by watering from the top of the seedling box with a watering device.However, it is not possible to sufficiently irrigate the medium in a short time. In the present invention, in the soil mixing device before being put into the filling hopper, an irrigation device is provided in a mixing section of two types of soils, so that sufficient humidification can be performed in a short time.

(D) Means for Solving the Problem The object of the present invention is as described above, and a configuration for achieving the object will be described below.

In a seeding plant in which a soil mixing device C and a soil filling machine B are arranged and two or more types of soil are mixed by the soil mixing device C, the soil mixed with the soil filling device B is filled into a seedling raising box. Before filling the inside, a watering device 31 for watering and humidifying the soil is arranged.

Further, as another embodiment, in the soil mixing device C, a watering device 31 is provided at a lower portion of a hopper storing two types of soil, at a mixed portion of both soils.

FIG. 7 is a perspective view of the watering device 31.

1 and 2, the overall configuration of the seeding plant will be described. The seeding plant of the present invention is composed of a seeding machine A and a soil filling machine B, each of which can be used as a single device. A soil mixing device C, a soil covering machine D, a storage conveyor E, and an arc conveyor F.

The soil filling machine B, the seeding machine A, and the soil covering machine D are arranged as a main line in a straight line.

A laterally pushable conveyor G is arranged at the rear end of the main line, and the direction is changed by the laterally pushable conveyor G so that the seedling raising box after sowing can be lightly transported toward the storage conveyor E. It is.

After the conveyance direction is changed in a right angle direction by the laterally pushable conveyor G, the conveyor is rotated by 90 degrees in a direction parallel to the main line by the arc conveyor F.

The transport direction is rotated 90 degrees by the arc conveyor F, and the transport direction is opposite to the transport direction of the main line.
It can be placed on top of

The flow of the storage conveyor E is reversed, but the soil filling machine B
And the seeding machine A and the soil covering machine D are arranged in parallel with the main line, so that the area required for installation of the seeding plant can be reduced.

Further, on the extension of the storage conveyor E arranged in parallel with the main line in the transport direction, before filling the soil into the soil filling machine B, the stones and impurities in the soil are removed, and the germination rate is increased. , In order to make plug seedlings with sufficient seedling soil mass attached,
A soil mixing device C for crushing, sieving, and mixing the soil is configured.

 Next, a detailed configuration will be described for each device.

The soil filling machine B is a device for filling the seedling pot placed in an empty seedling raising box with the soil uniformly and levelly.

That is, the seedling box is placed on top of the filling machine conveyor 30 at the left end position, and as much as the seedling box is taken out from below,
An automatic nursery box feeding device is provided in which the upper nursery box falls.

The seedling pot is inserted into the seedling box supplied on the filling machine conveyor 30 by the seedling box automatic feeding device.

In the seedling box above the seedling box automatic feeding device, the soil, which is stored inside the filling hopper 29 and mixed and humidified, is dropped and supplied with a certain thickness.

The filling machine conveyor 30 is provided with an extension conveyor 32, which enables connection with the next seeding machine A.

 Next, the configuration of the seeding machine A will be described.

In a conventional seeding plant that supplies a seedling mat for a rice transplanter, the seeds of rice are scattered and dispersed, so there is no need to drop the seeds accurately in each pot of the seedling raising pot as in the present invention.

On the other hand, since the seeds are small in the vegetable seeder, it is difficult to seed a certain number of seeds accurately in the pot if the seeds are sprayed. A vacuum seeding apparatus is arranged on which a fixed number of seeds are adsorbed by a vacuum seed pickup apparatus and dropped and sowed in each pot.

 Next, the earth covering machine D will be described.

The soil covering machine D is for sowing the soil in the pot by the sowing machine A, and then covering the seeds with a thin soil and watering.

The soil for the covering is stored in the covering hopper 36,
Irrigation is performed by a cover soil watering device 37.

Next, the soil mixing device C in FIGS.
The configuration will be described.

In the soil sieving / mixing machine C, two types of soils are mixed to form a soil.

That is, the soil is supplied to the peat hopper 16 and the vermiculite hopper 23, respectively.

In the case where the soil is a large soil mass or a lot of impurities such as peat moss, a soil crushing device 17 is provided to break the soil into fine soil.

Among both soils, peat moss is a soil with lots of stones, soil lumps and impurities, crushed by a spiral crusher placed in the crusher 17, and only fine soil is selected by a sieve.
The horizontal conveyer 18 and the vertical conveyer 21 convey and supply the second pete morph hopper 22.

The stones, lumps and contaminants remaining inside the crushing device 17 are discharged to the outside by the discharge chute 40 shown in FIG.

A vermiculite hopper 23 is disposed alongside the second peat moss hopper 22, and the peat moss and vermiculite are mixed at the lower conveyors 25 and 26.

The mixed soil is lifted and conveyed by the horizontal conveyor 27 and the vertical bucket conveyor 24, and is put into the filling hopper 29 of the soil filling machine B described above.

In the present invention, the point that a watering device is conventionally disposed at the rear of the soil filling machine B to water the soil after filling the seedling raising box is changed, and the vermiculite hopper 23 and the second peat hopper 22 are replaced. Lower conveyor 25 provided at the bottom
-The irrigation device 31 is arranged at a position between 26.

The lower conveyors 25 and 26 are rotating in opposite directions, and both soils in the mixing screw conveyor 27 at the center thereof fall.

Therefore, it is possible to sufficiently humidify the inside of the soil by irrigating the falling portions of the peat moss and the vermiculite falling from the lower conveyors 25 and 26 with the watering device 31.

The watering device 31 has a shower shape in which a hole is formed in a pipe, and the shower can be stopped and switched with watering by an opening / closing cock.

(F) Effects of the Invention The present invention is configured as described above, and has the following effects.

First, in the conventional soil filling machine B, when the surface of the soil after filling is irrigated and humidified by a watering device,
If the soil is a mixed soil of peat moss and vermiculite, it is difficult to penetrate into the interior, it may remain on the surface only and evaporate, lowering the germination rate, but as in the present invention, By irrigating and humidifying the soil before filling the seedling raising box, it is possible to evenly humidify the corners of the soil in the seedling raising box, so that it was possible to eliminate the occurrence of a problem that the germination rate was lowered. .

Secondly, by providing a watering device 31 in a mixing portion of both soils at a lower portion of a hopper storing two or more types of soils, a mixing device for soil and a mixing device for humidification can be used. The soil mixing device C having a simple configuration can be obtained.
