Abstract

PURPOSE:To obtain a grain bag capable of maintaining its rigidity when it is being used and being folded up when it is not in use by a method wherein the bag having a supply opening at its top and a hanging means is made of a flexible material, and the bag is provided with a plurality of hollow posts capable of being filled with a gas such as air and with an air filling opening. CONSTITUTION:A bag 2 is made of a flexible material such as synthetic resin and cloth and provided with a supply opening 1 at its top and a hanging means 4 above the bag 2. As the material for use in forming the structure of the bag 2, a plurality of vertical and horizontal hollow posts 5 capable of being filled with a gas such as air are provided and an air filling opening 6 is provided leading to a part of the posts 5. To attach the grain bag 2 to an air supply machine, the air filling opening 6 of the folded grain bag 2 is connected to the end of a hose of a compressor or the opening of the exhaust pipe of a truck. In this way the hollow posts 5 of the grain bag 2 are filled with the gas to be made rigid so as to give the bag its shape. To carry or store the bag after completion of operations, the posts 5 can be deflated back into a flexible condition and then folded up.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a grain bag and can be used in combine harvesters and the like.

[Prior art]

Conventional grain bags of this type are 1, for example, Japanese Patent Application Laid-open No. 60-91920.
As described in the publication, the shape cannot be secured until the grain bag of one machine is securely installed in the installation position, and it is extremely unstable.

In other words, this type of grain bag is made of a flexible material such as synthetic resin, so it is foldable;
It lacks rigidity, and unless it is filled with the contents, it will not be able to hold its shape and stand upright with its own blade.

[Problem to be solved by the invention]

This type of grain bag is required to be foldable so that it can be stored in a pouch when not in use, and to be able to stand stably even when empty when in use, in order to increase work efficiency. . However, the conventional grain bags mentioned above are made of a flexible material, so although they can be folded, they cannot be used in a standing position when empty. It took time and effort to attach it to the grain discharge position, which caused a decrease in work efficiency.

Therefore, the present invention aims to realize a grain bag that can ensure rigidity during use and can be folded when not in use.

[Means to solve the problem]

The present invention uses the following technical means to solve the above problems.

That is, a bag 2 having a supply port 1 at the top is made of a flexible material such as synthetic resin or cloth, and a hanging device 4 for lifting the bag 2 upward is attached to the bag 2. It is a grain bag in which a plurality of hollow pillars 5 which can be filled with gas such as air in the vertical and horizontal directions are provided on the material, and an air inlet 6 is provided in a part of the pillars 5.

[Action/Effect]

First, when attaching the grain bag 2 to the machine 3, connect the air inlet 6 of the folded grain bag 2 to the end of the compressor hose or the opening of the truck exhaust pipe (in the case of the example). . Then, the hollow pillars 5 of the grain bag 2 are filled with gas to maintain rigidity and secure the shape of the bag.

Therefore, the grain bag 2 can maintain its standing position even when empty, and can be attached to the machine 3 in the state shown in FIG.

Next, when the work is finished and the bag is to be transported or stored, the air can be removed from the pillars 5 and the bag can be folded back to its original flexible state.

As described above, this invention has a structure in which a grain bag made of a flexible material is provided with hollow pillars in the vertical and horizontal directions, and the pillars can be filled with gas. Since it can be folded and maintains rigidity when in use, it can be folded down to a smaller size when transported or stored empty, and when working, it can be used in a standing position, further improving work efficiency. has.

〔Example〕

The grain bag 2 is a rectangular bag made of synthetic resin materials P and P, and a circular supply port 1 is provided at the top.

The grain bag 2 is provided with vertically hollow pillars 5 in a square shape, and horizontal pillars 5 are formed at the lower edge and the upper edge.

The vertical and horizontal sides of this pillar 5 communicate with each other, and an air inlet 6 to which a hose 9 of a compressor or muffler 8 can be connected is provided in a part of the pillar 5.

The hanging tool 4 is composed of a string so that it can be hooked and lifted when a bag filled with grains is lifted by a lifting crane 7 equipped on the machine.

The single-cap fitting 10 has a ring shape that fits the cylindrical supply port 1, and is pivoted to the hanging device 4 so that it can be fitted into the supply port in the working state to ensure an upright state. .

If Velcro is attached to the side of the grain bag 2, it will be convenient when filling it with grains and loading it onto a truck or during storage.

Note that the machine 3 is a combine harvester, and is configured by providing a pedestal 14 under the discharge port 13 of the grain lifting cylinder 12 of the threshing machine 11.

When the work is started with the above configuration, the grain bag 2 will be
If the air inlet 6 is connected to the muffler 8 of the truck and the engine is started before installation on the machine 3, the vertical and horizontal pillars 5 will be sequentially filled, allowing the vehicle to stand in an empty state.

Next, the supply port 1 of the grain bag 2 is connected to the cap 1 of the hanger 4.
0 from above and secure it.

The grain bag 2 prepared as described above is placed on the pedestal 14 of the machine 3, and the discharge port 13 of the grain lifting cylinder 12 is inserted into the supply port 1.

Then, when the reaping and threshing operation is started, the threshed grains are supplied to the grain bag 2 through the grain lifting cylinder 12 and the discharge port 13. When the grain bag 2 is filled with grains, the hanging tool 4 is engaged with a crane 7, the grain bag 2 is lifted up, and the grain bag 2 is transported to a truck on an adjacent farm road.

Next, when carrying an empty bag, use the grain bag 2.

The air inlet 6 is opened to remove gas from the column 5, and the column is folded down to make it smaller.

As described above, the grain bag 2 according to the present invention has a feature that it can be folded into a small size when not in use, and when in use, the column 5 is filled with air so that the bag can remain standing when empty.

Then, in the grain bag 2, whether the exhaust gas is in the air inlet 6 or
