Description

[Detailed Description of the Invention] (Purpose of the Invention) The present invention provides for, when transporting a seedling box in which young seedlings have been grown, to an appropriate location, the seedling box is orderly and efficiently loaded onto the carrier platform and transported. It relates to equipment for
In particular, it is an object of the present invention to provide a seedling box transport frame having a novel structure with improved loading efficiency and product unit price, and a method for transporting seedling boxes using the frame.

(Prior art) Many of the devices that have been commercially available to date for loading and transporting seedling boxes containing grown seedlings onto the carrier platform are made by framing steel molds to a size suitable for the carrier platform. The structure is such that the shelves on which the seedling boxes are placed are formed vertically in multiple stages, and the seedling boxes are placed flat on each of the framed shelves and transported. there were.

In the case of this conventional device, first of all, if you try to realize a structure that can load a large number of seedling boxes, the overall shape will be quite large, and the handling of the device will be extremely inconvenient. Instead, it is not only inconvenient to store when not in use, but also has the disadvantage that the unit cost of the device itself is quite high.

Secondly, since the seedling boxes are laid flat and stacked vertically, they are quite tall.
Especially when used on the loading platform of a truck, loading and unloading the seedling boxes that are placed or placed on top becomes very difficult, making it difficult for women and girls to work. The situation was such that it was impossible to avoid.

The present invention was developed and completed in order to address such conventional drawbacks, and its configuration is as detailed below.

(Structure of the Invention) As clearly understood from the representative embodiment of the present invention shown in the drawings, the seedling box transport frame of the present invention includes a main frame 1, a support frame 2, a box stopper 3, It basically consists of:

The main frame 1 is constituted by a pair of strong members such as steel materials that are arranged substantially horizontally in parallel, and are connected at both ends and at a suitable place in the middle by a connecting member 11 to form a rectangular frame as a whole. The interval between main frames 1 and 1 is
The dimensions approximately match the dimensions of the seedling box 7, and depending on how the seedling boxes 7 are arranged, either the short side dimension or the long side dimension of the seedling box 7 is selected as the spacing dimension.

The support frame 2 has attachment portions 21.21 to the main frame 1.21 formed at both ends thereof, and abuts and supports the rear surface of the seedling box 7 at an upper position separated from the attachment portions 21 by a predetermined distance. It has a shape that has a back rest part 22, for example,
In addition to bending the steel rod as in the illustrated example, although not shown in the figure, a structure in which attachment parts are formed at both lower ends of the steel plate that fits between the main frames 1 and 1 can be used in a similar manner. #R capability can be achieved.

This support frame 2 has both attachment parts 21 and 21 attached to the pair of main frames 1 and 1 by appropriate means, and is set at a predetermined angle θ (>90 degrees, optimally The mounting structure is such that the mounting portion 21, 21 itself is tilted at a predetermined angle to the main frame 1 and then welded or by other means.
For example, it is fixed by a known means such as a plug-in structure.

Further, the support frame 2 can also be configured to be detachable from the main frame 1.1, in which case the attachment portion 21.2 of the support frame 2 to the main frame 1.1
The fixing means in No. 1 must be something other than welding. For example, in the case of a bent steel rod as in the illustrated example, a detachable structure that takes advantage of its elasticity may be used. However, it is possible to adopt various structures, such as a structure in which a splint is attached using screws or screws, or a structure in which a socket member is used.

On the other hand, the box fixing protrusion 3 is attached to the attachment part 2 of the support frame 2.
1, and is formed at a position spaced apart by approximately the thickness dimension of the seedling box 7, and the lower end of the seedling box 7, which is supported by the back support part 22 of the support frame 2, is not turned over. In the illustrated example, the box fixing protrusions 3 have a structure that protrudes inward from the side of the main frame 1, but this structure does not necessarily have to be used. The present invention is not limited to this, and in some cases, it may be formed as a projecting shape from below to diagonally upward (in the direction of inclination of the support frame 2), and as shown in the perspective view of FIG. The frames 12 may be arranged in parallel, and the box fixing protrusions 3 may be provided to protrude from the frames 12.

The embodiments shown in the above embodiments are basically adopted in two or three stages in the vertical direction depending on the width of the loading platform of the transport vehicle 9 such as a truck. If it is necessary to use such a multi-stage system (increasing the amount of transport), for example, it is necessary to use a separate frame for transporting seedling boxes. Although it is possible to form a body frame frame A and place a seedling box transport frame containing seedling boxes 7, 7, etc. therein, there is no way to do so. However, this method has the same drawbacks as the previous methods, and is not necessarily a desirable solution.

One embodiment of realizing such a multi-stage structure is shown in FIG. 4.

That is, a plurality of fixing portions 13 are formed in a well-balanced manner on the pair of main frames 1.1 of the seedling box transport frames shown in each of the embodiments described above, and these seedling box transport frames are vertically separated and reversed for a predetermined distance. Parallel and corresponding upper and lower fixing parts 1
By interposing and fixing support rods 4 between 3.13, a multi-stage seedling box transport frame is formed.

The structure of the fixing part 13 is not particularly limited as long as it can be reliably connected to the support rod 4. For example, the fixing part 13 may receive the end of the support rod 4 in a plug-in manner as in the illustrated example. , or may have a structure in which sheath rods that are screwed are welded together.The number of sheaths to be formed is determined to be optimal depending on the weight of the seedling box to be accommodated on the seedling box transport frame.

The seedling box transport frame of the present invention having the above-mentioned configuration is normally placed on the loading platform of the transport vehicle 9, and the seedling box 7 in which young seedlings 8 are planted is inserted diagonally into each support frame 2. After accommodating a large number of seedling boxes 7, the transport vehicle is moved to the appropriate location, and then the seedling boxes 7 are taken out one by one while being lifted diagonally upward one by one.
. . . efficiently transported at - degrees. At this time, each seedling box transport frame mounted on the transport vehicle 9 is not particularly moved and is left stationary.

However, if the transport vehicle 9 is small such as a light truck, and the height of the loading platform is low and the width is not very wide, the above transport method will not cause any problems, but the transport vehicle 9
Depending on the size of the object, it is extremely convenient to adopt the following transportation method.

That is, each seedling box transport frame has a structure that allows it to be pulled out one after another from the transport vehicle loading platform, for example, rollers 5 and other members for reducing frictional resistance are incorporated in appropriate positions on the lower surfaces of the main frames 1, 1, or they are installed in the main frame. Only the seedling box transport frame, which is placed on the loading platform by interposing it between the frame 1.1 and the loading platform, and is necessary for loading and unloading the seedling box 7 in which young seedlings 8 are planted, is moved each time. This is a method of transporting seedling boxes by pulling them out from a loading platform.

In addition, when adopting this method, in addition to interposing a friction reducing material such as rollers 5, 5, etc. on the lower surface of the main frames 1, 1 as described above, it is necessary to A fifth stand member 6 for holding the frame in a substantially horizontal position is installed in advance along with the main frames 1, 1, and the stand member 6.6 can be used in a rotary and drawable manner as needed. If the structure shown in the figure is adopted, it will become even more convenient.

FIG. 5 is a side view showing a state in which one seedling box transport frame is pulled out to the rear side of the loading platform of the transport vehicle 9 using this method.

(Function and Effect) The seedling box transport frame of the present invention having the above-mentioned configuration adopts a structure in which the seedling box in which young seedlings are planted is housed in an extremely diagonal position that is almost vertical. This means that not only can the amount of seedling boxes transported be far greater than when transporting them using the conventional flat storage shelves, but also a large number of seedling boxes can be taken out at the same height. Since it also has the following advantages, the efficiency of loading and unloading seedling boxes will be dramatically improved. This advantage is achieved in the case of multi-tier seedling box transport frames.
This will be further facilitated, and if the method for handling and transporting these seedling box transport frames is carried out in such a way that they can be pulled out one after another from the carrier platform, it will become even more outstanding.

In addition, compared to conventional flat shelves, the sideways are extremely simple and compact, and it is easy to manufacture and can be provided at low cost.
, 1, the supporting frames 2, 2, .

Furthermore, the advantage of having a compact structure is that it not only makes handling of the seedling box transportation frame easy, but also makes it possible to secure storage space when not in use, that is, in the off-season except for special rice planting, or to facilitate manufacturing. It is also very advantageous in terms of storage, shipping, sales, etc. of the product later.

On the other hand, since the support frame 2 is configured to be detachable from the main frame 1.1, but cannot be rotated,
Even if there is a sudden stop during transportation with fewer seedling boxes 7 to be loaded, there is absolutely no possibility that the support frames 2, 2, etc. will rotate due to the reaction. This has the effect of preventing the seedling box 7 from falling out in the scene.

As Unegami explains, the seedling box transport frame of the present invention is superior not only in its ease of production and manufacturing cost, but also in all aspects such as ease of handling the product at the manufacturing and shipping stages, ease of handling during work, and ease of storage for farmers. It has excellent features not found in previous models.
