Description

[Detailed Description of the Invention] (Object of the Invention) The present invention involves filling a seedling box with soil for the seedling and filling it at a constant pressure in order to form a seedbed for sowing seeds such as seed rice and raising seedlings. This relates to a new structure for a soil filling device for seedling boxes that compresses and levels the soil, and is particularly suitable for forming seedbeds using paper pots, which requires filling and leveling the soil into the seedling box. The purpose is to realize a soil filling device for seedling boxes.

(Prior art) In recent years, technology for sowing seeds such as seed rice and raising seedlings has progressed rapidly, and automatic seedling box feeding devices, soil filling devices, seeding devices,
Irrigation systems, etc., have been improved and developed as fully automatic systems that are linked individually or as a whole, and have been effective in many farmers.

Among these things that have been developed and put into practical use,
Looking at the processes before and after the soil filling device, many of them are
Fill the seedling box almost evenly with soil for seedlings, apply appropriate pressure, and sow seeds such as rice seeds evenly, or create furrows while applying appropriate pressure to the filled soil. In most cases, seeds were sown in the grooves.

In the case of this method, if you take into consideration the germination, rooting, growth, etc. of the sown seeds, there is no need to pressurize and tamp the nursery soil filled in the seedling box so strongly before sowing. The reality is that we are more concerned about the negative effects of tamping too strongly, so we have put our heart and soul into developing mechanisms and devices that allow for the realization of appropriate tamping pressure. That's enough to say.

On the other hand, in order to grow healthy seedlings, we use a paper seeding device called a paper pot, which has many small squares at regular intervals, and place the paper pot upside down beforehand in the soil. After filling and compressing it, turn it over again so that it is facing up and put it back in the seedling box. Then, sow the seeds evenly in each square with the bottom already filled with soil, and then cover it with soil. Recently, methods for sowing and raising seedlings have been attracting attention.

This method always involves the process of turning the paper pot upside down again to face up, so if the compaction density of the soil is low at the initial stage, it will be difficult to carry out this process. It was necessary to pack the soil as strongly as possible because there was a risk that the soil in the squares would spill out, making it difficult to carry out the work safely.

However, none of the existing soil-filling devices originally adopted such a configuration for the reasons mentioned above.
Therefore, as a matter of course, it is not possible to adopt these conventional methods, and since it does not appear that a suitable soil-filling device has been developed yet, the method of sowing and raising seedlings using paper pots has not been adopted. The reality is that we are still complacent with the situation in which it is not widely popularized.

This invention was developed and completed in view of such circumstances, and its configuration is as detailed below.

(Structure of the Invention) As can be understood from the representative embodiment of the invention shown in the drawings, the soil filling device for seedling boxes of the invention includes a frame 1,
This is a soil filling device for a seedling box that has a conveyance mechanism 2, a soil filling mechanism section 3, a pressure q-ler 4, and a support roller 5 as basic components.

The frame 1 consists of a pair of left and right shaped steel horizontally arranged side by side with an interval approximately equivalent to the width of the seedling box, and is held at a predetermined height from the floor by stands 11, 11... It will be installed. And if necessary,
At the front and back ends of the frame 1, or at either end,
It is also possible to form a connection part for connecting to a functional device on the ground, such as a seeding device, a soil covering device, or an irrigation device.

A conveying mechanism 2 consisting of rubber rolls 21, 21, etc. is installed between the pair of left and right shaped steel forming the frame 1, and is planned to be rotated or moved at a constant speed by an appropriate power source. .

By this conveyance mechanism 2, the seedling boxes 7, 7, . . . are conveyed in a constant direction (from left to right in the drawing) at a constant speed.

In this way, the soil-filling mechanism section 3 is installed at a proper location on the frame 1 in which the transport mechanism 2 is incorporated, and positioned a predetermined distance above the upper surface of the frame 1.

The soil filling mechanism section 3 includes a hopper 31 and a soil feeding belt 32.
In addition to the structure shown in the embodiment, which includes the soil falling amount adjusting damper 33, any known structure of the soil filling mechanism can be adopted. Not even. ' The pressure roller 4 is located on the encroaching part, that is, on the conveying direction (right side in the drawing) side of the conveying mechanism 2 from the installation position of the soil filling mechanism section 3, and from the top surface of the conveying mechanism 2 into the seedling box 7. It is pivotally supported so that its outer circumferential surface is located at a position separated upward by a height corresponding to the compacting surface of the filled soil.

The roller 4 may be simply formed into a cylindrical shape, but in order to prevent soil from falling from both sides during forced compression, as shown in the example, both ends in the width direction are formed. It is extremely convenient if the flange plate 41° 41 is integrally formed in advance. Furthermore, the collar plate 41
If the regulating side plates 44, 44 are formed close to the front of the roller 4 so as to have the same width as 41 degrees, it will be more effective.

Note that the height position of the roller 4 may need to be changed due to adjustment of the packing density or differences in the type of seedling boxes 7, so the roller 4, which is supported by the shaft support side plates 43 and 43, Both ends of the shaft rod 42 are connected to the shaft support side plates 43, 4.
Bearings that can be adjusted up and down relative to 3 can be formed in the structure, or, as in the illustrated embodiment, adjustment plates 45, 45, .
It is preferable to form a structure in which the necessary number of sheets are interposed and attached so as to be detachable.

At a lower position separated from the pressure roller 4 by a predetermined distance, a support roller 5 is arranged parallel to the roller 4, and the pressure roller 4 and the support roller 5 form a pair of upper and lower rollers. This support is designed to prevent the seedling box 7 from bending downward due to the packing force applied by the packing pressure roller 4, thereby reducing the packing pressure strength that should be applied to the soil 8 filled in the seedling box 7. The rollers 5 function to hold the bottom plate of the seedling box 7 in the correct position.

The arrangement of the support rollers 5 in parallel at the regulated position is as follows:
Although it may be formed independently of the frame 1, if the conveyance mechanism 2 in the frame 1 is based on rubber rolls 21, 21, etc., as in the illustrated example,
It is also possible to form a common rotating shaft 22 between the rubber rolls 21 and 21.

Depending on the application, the combination of the pressure roller 4 and the support roller 5 forming an upper and lower pair can sufficiently exhibit its function even if it is made up of just one set, but it can further enhance the pressure effect. When necessary, 2 pairs, 3 pairs...
By combining multiple sets such as...
It will be possible to fully achieve that purpose.

In the case of a combination of multiple sets, the distance between the pressure roller 4 and the support roller 5 of the set located on the transport direction side of the transport mechanism 2 is set to be slightly narrower. By arranging them in such a regulated manner, it is possible to achieve reliable filling pressure against the self-recovery nature of soil.

A soil scraping member 6 can also be provided in parallel to the pressure roller 4 combined as described above for the purpose of brushing off soil that may adhere to the surface thereof.

Although the soil scraping member 6 is not shown in the drawings, in addition to the one made of a rotating brush as shown in the embodiment,
It is possible to adopt various structures such as spatula-shaped ones and stretched wire-shaped ones.

These soil scraping members 6 may be arranged side by side as independent members for each roller, or two may be arranged one behind the other as in the embodiment.
If the rotary brush shared by the book-loading rollers 4 and 4 is used as the soil scraping member 6, and the position of its parallel arrangement is carefully considered, it will save money and improve the power transmission system. It is also extremely convenient.

Note that the power transmission method of the pressure roller 4, support roller 5, and soil scraping member 6 is not particularly limited, and may be any suitable method, but depending on the conveyance speed of the conveyance mechanism 2 and In view of these considerations, the most ideal method would be to use a system in which the transport mechanism 2 is interlocked with a chain or a belt. The transmission speed ratio with the conveying mechanism 2 at that time must be selected to be an optimum ratio, taking into consideration the pressure effect of the pressure roller 4, the conveyance condition of the seedling box 7, and the like.

(Operation and Effect) The soil filling device for seedling boxes of the present invention having the above-described configuration has the following features.

First of all, by realizing a configuration that combines a compaction roller and a supporting roller, it is possible to use soil that requires quite strong compaction strength, such as when filling a seedling box with a vapor pot. In this case, the presence of the support roller that directly supports the bottom plate of the seedling box reliably prevents the seedling box itself from bending, so that the packing force from the pressure roller in this invention is applied directly to the seedling soil in the seedling box. In addition, it is possible to achieve uniform and firm filling of the soil in the seedling box as planned.

This effect could not be achieved by simply incorporating a pressure roller on the conveyance mechanism and relying only on the belt and rubber roll of the conveyance mechanism, which was the case with previous Jonin devices. It can be of no outstanding effect and must be highly appreciated.

In particular, it is more effective when multiple pairs of upper and lower pressure rollers and support rollers are combined, and it has self-recovery properties, so that it cannot be evened out by simply passing a rotating roller or applying pressure. - In addition, it is possible to overcome the difficulty of compacting soil for seedbeds, etc., where it is difficult to achieve firm compaction.

This effect cannot be achieved even if multiple pressure rollers are placed side by side at different height positions, but this effect is not achieved by simply installing a support roller in addition to the conveyance mechanism. It should be said that this achievement was possible only because the unique structure of the soil filling device for seedling boxes was developed and perfected according to the invention.

Note that this effect can be expected even if the support roller installed at a predetermined position below the pressure roller is intentionally shifted to some extent in front of the pressure roller.

The second feature is that the structure of this invention is based on the knowledge that not only the self-restoring properties of the soil but also the flexure of the seedling box itself that houses it makes it difficult to compress the soil. Although it has been developed and completed, it is extremely simple and has a structure that can be easily incorporated into conventional models that are already in practical use, making it easy to manufacture. This product can be provided at a unit price that is not that different from previous products, and it will greatly contribute to the spread of soil-filling work that requires filling soil with a fairly compacted volume, such as soil-filling using vapor pots. This means that it is something that can be contributed to.

This effect will be highly appreciated, especially for rice farmers who aim for stable harvests, as it will make it easier to adopt the vapor pot seedling raising method.

Thirdly, since the soil filling device for seedling boxes of the present invention can have a soil scraping member built into the pressure roller, no matter what kind of soil for seedlings is adopted, There is no need to be careful about monitoring or wiping away the soil that adheres to the pressure roller during the soil filling operation, which guarantees highly efficient work.

This effect can be achieved by installing a soil scraping member consisting of a common brush in a configuration in which multiple pressure rollers and supporting rollers are combined, and between two successive pressure rollers. In addition to the above-mentioned features, this has the advantage that it not only saves the amount of materials used, but also has the excellent effect of making the overall shape compact.

As mentioned above, this invention is unprecedented in that it ensures soil-filling work, which is indispensable for seed sowing and cultivation, especially soil-filling work that is quite firm. It is said to have a good effect,
It can be said that this invention has excellent features, as it is easy to manufacture, can be provided at low cost, and has excellent usability.
