Description

[Detailed description of the invention] [Field of industrial application] This invention is a grain bag in which the upper edge opening of the bag faces the discharge duct of a combine harvester, etc., and the grains sent out from the duct are accommodated. Regarding the handle structure of a storage bag.

[Conventional technology and its problems]

Traditionally, agricultural combine harvesters have two types of spacing between support rods that support grain storage bags, wide and narrow depending on the model (by manufacturer), and accordingly, the spacing between the attachment members such as eyelet holes on the storage bags has also changed. Since the bags were standardized into two types (see Figures 4A and B), there was an inconvenience in that there was no compatibility between the bags with these different standards.

On the other hand, this type of grain storage bag for combine harvesters is
When storing grains such as raw paddy, the weight is approximately 30Kg.
In addition, because the entire bag had expanded, women and girls, who have been the main workers of farmers in recent years, were forced to endure great hardship in transporting and moving the bag.

As a means for facilitating the transportation of the grain storage bag mentioned above, for example, as seen in Japanese Utility Model Publication No. 57-37713, handles protruding from the upper and lower edges of the main body of the bag are sewn separately. However, with this structure, the handle has to be sewn separately from the main body of the bag, which not only complicates the bag-making process but also makes the bag particularly difficult to sew. When using sackcloth such as net fabric, it is necessary to separately sew reinforcing cloth to the attachment portion of the handle, which further complicates the sewing process.

The main purpose of this invention, which was created in view of these circumstances, is to maintain compatibility of the bag itself with respect to the locking rods, which have different installation intervals depending on the combine harvester model. , it is possible to efficiently sew a handle to the main body of the bag.

[Means to solve the problem]

The present invention is a grain storage bag in which the upper edge opening can be opened and closed and has locking members such as eyelet holes on both sides of the grain storage bag, which are attached front and back to the center of the upper edge opening of the main body of the bag. The length of the upper handles is made to match the narrowest standard spacing between the locking rods, and to simplify the sewing work, each upper handle is designed with a fastener attached to each inner surface of the upper edge opening. In addition, when the lower edge of the main body of the bag is folded back and sewn together, the lower handle is sewn to the center part of the lower edge at the same time.

[Effect]

The grain storage bag with a hand according to the present invention can be used by hanging it on a narrow locking rod by the upper handle, so it has the effect of making the bag main body compatible, and also has the above-mentioned effects on the bag main body. By sewing the handle at the same time, the sewing effort is significantly simplified and the strength of the handle is increased.

〔Example〕

Below, we will describe an example in which the grain storage bag of the present invention is applied to a net bag. 1 is constructed of a net bag made by knitting synthetic resin monofilament of an appropriate thickness to an appropriate width. 2 is a reinforcing band sewn to surround the upper edge opening of the bag main body, or 3 is a fastener made of a base fabric 3' sewn to the inside of each of the front and back of the opening. be.

Furthermore, 4a and 4b are handles sewn to the center portions of both upper and lower edges of the bag main body, and the upper handles 4a and 4a facing each other are attached to the inner surface of each side of the opening of the bag main body and the above-mentioned upper handles. When sewing the base cloth 3' of each fastener 3, each handle 4 is attached between the two.
They are sewn simultaneously with the ends of the handles 4a and 4a interposed between them.
The length of the lower handle 4b is set to meet the narrow standard, and the lower handle 4b is attached to the upper handle 4 at the lower edge folded part of the main body of the bag.
Each end is overlapped at the position corresponding to a and sewn at the same time as the above-mentioned folded portion is sewn.

In addition, reference numeral 5 in the figure indicates a locking member such as an eyelet hole provided at both ends of the upper edge or at the four corners of the main body of the bag. shall match the spacing (not shown). Further, in FIG. 3, numeral 6 indicates a locking rod of the combine with narrow standard spacing, and numeral 7 indicates a discharge duct.

In addition, the upper handles 4a, 4a are not limited to being clamped between the inner surface of the main body of the bag and the base fabric 3' of the fastener as in the above example;
The fact that a and 4a are simultaneously sewn in relation to the base cloth 3' of the fastener simplifies the bag making work and maintains the strength of the handle.

[Effect of idea]

When the grain storage bag with handle of the present invention having the above-mentioned structure is used in a combine harvester with a wide locking rod spacing, locking members 5 provided at both ends of the upper edge are used to hold the storage bag. However, for combine harvesters with narrow spacing between the locking rods, the main body of the bag can be easily attached by using the upper handle 4a instead of the locking member 5. This makes it possible to achieve mutual compatibility between bags, something that could not be expected in the past.

Furthermore, since the storage bag of this invention has the upper and lower handles 4a and 4b sewn together at the same time when the bag main body 1 is sewn, the handles are sewn separately with partial reinforcing fabric added, unlike conventional products. In addition to significantly improving the efficiency of bag-making work compared to those that are sewn to the bag, in this case, the bag after storing grains can be transported and moved much easier by using the above-mentioned upper and lower handles. This type of grain storage bag has excellent characteristics.
