Description

[Detailed Description of the Invention] (a) Field of Industrial Use The present invention relates to a configuration in which seedling pots for growing vegetable seedlings such as spinach, carrot and radish are filled with seeding soil.

(B) Conventional Technology Conventionally, the technology used for the vibration device when filling the seedling raising pot with soil has been known.

For example, the technology described in JP-B-58-28509, JP-B-60-36056, JP-B-49-9709, JP-B-54-8125, and JP-B-50-2847. Is like.

(C) Problems to be solved by the invention However, in the techniques described in JP-B-58-28509, JP-B-60-36056, JP-B-49-9709 and JP-B-45-8125, , All of them are dedicated sowing soil filling machines, which are filled by directly vibrating the table provided on the upper part with a cam mechanism and a mallet, so that the soil can be overbounced or overflowed and evenly filled. It is difficult to do so, and the work of filling the pot or the paper cylinder with the soil and the work of replacing the pot or the paper cylinder must all be done manually, resulting in a very inefficient problem. .

On the other hand, in Japanese Utility Model Application Laid-Open No. 50-2847, a feeding device is arranged above the transfer conveyor, and a mechanism for vibrating a nursery box or a pot in the middle or at the end of the transfer path of the conveyor is provided. Although the above problems have been solved, there is a pot or pot in the nursery box in order to vibrate the nursery box or pot in the middle or at the end of the transfer path of the conveyor separated from the feeding device. If the part is filled too little, vibration will be applied after that, so that only that part will be depressed, and it will take time and effort to refill before seeding, or without refilling. When sowing, there is a problem that subsequent inventions will be hindered and normal seedlings cannot be used.

(D) Means for solving the problem The purpose of the present invention is to solve the above-mentioned problems,
Next, a configuration for achieving the object will be described.

In a soil filling device for inserting seedling raising pots 2 in which a large number of pots for raising seedlings 1 are arranged in parallel and for uniformly filling seedling raising seeds 2 with soil, a conveyor belt 4 made of an elastic body is provided, and seedlings are raised above the conveyor belt 4. A soil hopper 10 and a scraping brush 8 are provided in this order from the upper side of the transport path of the box 1, and a soil feeding conveyor 9 is provided below the soil hopper 10.
Is provided, and the vibrating device 7 is disposed between the scraping brush 8 and the vicinity of the soil dropping point at the end of the soil feeding conveyor 9 and below the transport belt in contact with the transport belt.
The seedling raising pot 2 is vibrated via the conveyor belt 4 and the seedling raising box 1.

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

FIG. 1 is a side view of the soil filling device, FIG. 2 is a front view of the same, FIG. 3 is a plan view of the same, and FIG. 4 is a side sectional view showing a configuration in which a vibrating device 7 is attached to the lower surface of the conveyor belt 4. , Fifth
The figure is a side sectional view showing a sensor mechanism for intermittently driving the seedling raising box 1 in response to a seeding operation of a point seeding type seeding machine, and FIG. 7 is a side sectional view showing a dimensional relationship between the seedling raising box 1 and the seedling raising pot 2. is there.

The soil filling device of the seeding device will be described with reference to FIGS. 1, 2, and 3.

The soil filling device is a part of a device configured as a whole sowing plant, and continuously supplies the seedling raising boxes 1 first stacked in multiple stages below the soil hopper 10 one after another.
11 are provided.

Then, the seeding soil stored in the soil hopper 10 in the unit pot of the seedling raising pots 2 arranged in the seedling raising box 1 successively supplied by the continuous supply device 11 is fed out.
It will fall out while being extended by.

Unnecessary portions of the seeding soil that have dropped into the pot of the seedling raising pot 2 are scraped by the rotation of the scraping brush 8 and are sequentially sent to the rear pot.

Then, the soil filled in the seedling raising pot 2 is irrigated by the irrigation device 12 to humidify it. The seedling-growing pot 2 is transported to the point-seeding type seeding device in a state where the pot of the seedling-growing pot 2 arranged in the seedling-raising box 1 is filled with the seeding soil in this manner.

However, since the seeding device is a point-seeding type seeder, the seedling raising pot 2 cannot be continuously conveyed, and is intermittently conveyed, and the pot that is just a recess is located under the seeding cylinder of the point-seeding type seeding device. There is a need.

In the present invention, the sensor 3 configured as shown in FIG. 5 and FIG. 6 detects whether it is the position of the pot recess 2b of the seedling raising pot 2 or the position of the partition recess 2a, and the soil feeding conveyor 9 for just At a position directly below the end of the pot, at a position where the pot recess 2b is located directly below the seeding tube of the point-seeding type seeding device,
The drive of the conveyor belt 4 is stopped.

For this reason, the sensor 3 of this configuration is configured to detect the presence of the partition wall convex portion 2a of the seedling raising pot 2.

The sensor 3 detects the position of the partition wall protrusion 2a, and the pot recess 2b is separated from the position of the partition wall protrusion 2a by a certain distance.
The position of is controlled by the control unit 6 so as to be located just below the end of the soil feeding conveyor 9 or directly below the seeding cylinder of the point-seeding type seeding device, and a signal for intermittently driving the drive motor 5 is transmitted. is there.

The structure of the sensor 3 shows a limit switch equipped with a mechanical sensor rod in the sensor 3a of FIG. 5, and in FIG. 6, compressed air is blown by the sensor 3c, 2 shows a pneumatic sensor that detects the presence of the partition wall convex portion 2a by the discharge pressure of.

A sensor 3b shown in FIG. 6 is a non-contact type sensor such as an electric capacitance or an optical switch.

Further, as shown in FIG. 6, it is also possible to arrange the two sensors with a certain space therebetween and to configure the confirmation circuit so as to stop when the partition wall convex portions 2a come to both positions.

By arranging the two switches, as shown in FIG. 7, it is possible to detect whether or not the separated state has occurred at the position where the front and rear seedling raising pots 2 are in contact with each other.

In FIG. 7, there is no change in the shape of the seedling raising pot 2 by opening a gap or pushing the seedling raising pots 2 against each other in a state where the seedling raising pot 2 and the seedling raising box 1 which are continuous in front and rear are in contact with each other. It is configured like this.

That is, the outer surface of the pot concave portion 2b of the seedling raising pot 2 is used as an inclined surface, and the inclined surface is the end portion, and the inner surface B of the seedling raising box 1 is exactly
At the position of, it is constructed so as to fit exactly.

In addition, in this state, the plan view external dimension A of the seedling raising pot 2,
The outer dimensions A of the nursery box 1 in plan view are configured to match.

In the overall structure as described above, the main part of the present invention is the structure disclosed in FIG. That is, since a large number of small pot recesses 2b are formed, the seedling raising pot 2
Simply dropping the seeding soil on top of the above does not sufficiently fill the inside of the pot recess 2b in a dense state.

If the inside of the pot recess 2b is not sufficiently filled, a space will occur between the seeds sown and the soil, and it will not be possible to provide sufficient moisture to the soil, which will result in germination. is there.

In the present invention, in order to eliminate such a problem, the conveyor belt for mounting and conveying the seedling raising box 1 containing the seedling raising pot 2 is vibrated vertically.

When the conveyor belt 4 vibrates, vertical vibration is more effective than lateral vibration to improve the filling effect.

Also, if you place the vibrating device away from the soil feeding device, if a portion of the seedling raising box, such as a pot or pot, is slightly filled, vibration is applied after that, so that only that portion appears to be depressed. Therefore, it takes time and labor to fill the seeds before sowing, and if seeding is performed without refilling, the growth of the seeds is hindered and normal seedlings cannot be used.

In the present invention, in order to eliminate such a problem, a soil hopper 10 and a scraping brush 8 are provided in order from the upper side of the transportation path of the nursery box 1 on the upper portion of the transportation bolt 4, and the soil feeding conveyor is provided below the soil hopper 10. 9 is provided,
A vibrating device 7 is arranged between the end of the soil feeding conveyor 9 and the scraping brush 8 and in contact with the conveyor belt 4 below the conveyor belt 4, and the conveyor belt 4 and the nursery box 1 The seedling raising pot 2 is vibrated.

Further, when the vibrating device 7 is directly applied to the lower surface of the nursery box 1, the soil may bounce or overflow, resulting in a problem that vibration is too strong.

In the present invention, in order to eliminate such a problem, the vibrating device 7 is arranged inside the ring of the conveyor belt 4 and vibrates from the lower surface of the conveyor belt 4 on the upper surface.

A slide plate 7a is provided at a portion where the vibrating device 7 contacts the back surface of the conveyor belt 4, and the conveyor belt 4 slides at the slide plate 7a portion, which greatly resists movement for conveyance. It is configured so that it can be done without.

(F) Effect of the Invention Since the present invention is configured as described above, the following effects are produced.

Firstly, a soil hopper 10 and a scraping brush 8 are provided on the upper portion of the conveyor belt 4 in this order from the upstream side of the transportation path of the seedling raising box 1, and a soil feeding conveyor 9 is provided below the soil hopper 10 to provide the soil feeding conveyor. A vibrating device 7 is disposed between the scraping brush 8 at the end of the sheet 9 and the scraping brush 8 and in contact with the conveyor belt at the lower part of the conveyor belt, and the conveyor belt 4 and the nursery box 1 are used. Since the seedling raising pot 2 is vibrated, the soil drops at the end of the soil feeding conveyor 9, and vibration is applied while the seedling raising pot 2 is being filled, so that the soil is filled in a dense state. Further, even if a portion of the seedling raising pot 2 is filled with a small amount of soil, since the scraping brush 8 is arranged on the lower side of the soil hopper 10, the pot located in front of the pot is Since the excess soil is sequentially filled in the rear pot, the pot that is slightly filled with soil is refilled with sufficient soil, and at the same time, the vicinity of the end of the feeding conveyor 9 and the scraping brush 8 are filled. Since the vibrating device is placed between the pots, the pot that has been filled with a small amount of soil will also be filled with new soil in a dense state, resulting in an overall dense and uniform soil. It is possible to fill the soil.

Secondly, when the vibrating device 7 directly contacts the bottom surface of the seedling raising box 1 and vibrates, the soil may jump too much or overflow, but via the conveyor belt 4 which is an elastic body. By vibrating, such a problem that the vibration is too strong can be solved.
