Abstract

(57) [Abstract] [PROBLEMS] To provide a grain transportation container that has a large storage capacity and can surely discharge the whole amount naturally. SOLUTION: A bottom plate 3 provided in a lower portion of a frame 2 is made swingable up and down by a bottom plate pushing-up means 4, and a lower portion of a hopper 5 accommodated in the frame 2 is supported by the bottom plate 3 and put into the hopper 5. When there is a large amount of grains, the bottom plate 3 becomes horizontal and the volume of the hopper 5 can be secured to the maximum, and when the grains are discharged, the bottom plate 3 tilts upward and the whole amount of grains can be discharged.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 This invention can keep a large capacity in the grain transport container, more specifically, in the hopper, and can discharge the whole amount of stored grain naturally without using special external power or human power. Regarding containers.

[0002]

[Prior art]

 For example, a container that can store and discharge grains is used to store the harvested grains and transport them by truck or the like.

In the conventional container, the bottom plate of the hopper, whose upper surface is open, is fixedly arranged in a forward downward slope so that the whole amount of stored grains can be discharged, and a discharge port is provided at the lower front part of the hopper. By opening the discharge port, the grains slide on the bottom plate and the whole amount is discharged.

[0004]

[Problems to be solved by the device]

 By the way, in the structure in which the bottom plate is fixed in a downward slope, the storage capacity in the hopper is smaller than the case where the bottom plate is horizontal by the amount of inclination of the bottom plate, and there is a problem that storage efficiency is poor.

Therefore, an object of the present invention is to provide a grain transportation container in which a bottom plate supporting a lower portion of a hopper has a variable angle in response to a change in weight of the grain, and can improve the storage efficiency of the grain. Will be done.

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, the invention of claim 1 is such that a frame having at least an upper surface and a front surface opened, and a lower part in the frame can be vertically swung about a position on the front surface side of the frame as a fulcrum. Has a bottom plate provided so as to be movable, an expandable and contractible bottom plate pushing-up means provided between the bottom plate and the frame, and a discharge port which is housed in the frame so as to be mounted on the bottom plate and which can be opened on the front side. It is composed of a hopper, and the inclination angle of the bottom plate is automatically changed according to the weight of the grains stored in the hopper.

Here, the hopper may have a flexible structure that follows changes in the inclination angle of the bottom plate, or the bottom plate pushing-up means may be formed of a gas spring.

[0008]

[Embodiment of device]

 Hereinafter, embodiments of the present invention will be described with reference to the illustrated examples.

As shown in the figure, the transport container 1 is made of various steel materials and pipes, and has a frame 2 formed into a rectangular cylindrical frame shape with an open upper surface and a peripheral surface. A bottom plate 3 provided so as to be freely movable, an expandable and contractible bottom plate pushing-up means 4 provided between the bottom plate 3 and the frame 2, and accommodated in the frame 2, and a lower part thereof is supported on the bottom plate 3. And a hopper 5 that is operated.

The bottom plate 3 is formed in a flat rectangular shape that can be accommodated in the frame 2, and its tip end is supported by a hinge 6 provided at the front part of the frame 2, and can be vertically swung with the hinge 6 as a fulcrum. Therefore, the bottom plate 3 is horizontally supported in a state of being overlapped with the middle rail 7 provided at the lower portion of the frame 2.

The bottom plate pushing-up means 4 is arranged on at least both sides of the bottom plate 3 by using a gas spring in the case shown in the figure, the upper end is pivotally connected to the bottom plate 3, and the lower end is attached to the lower part of the frame 2. .

This gas spring has a structure in which pressure gas is enclosed in an expandable cylinder, and the cylinder is expanded by the pressure gas. As shown in FIG. In the case of a load, the bottom plate 3 is pushed up in the extended state, the bottom plate 3 is held in a downward slope, and the bottom plate 3 contracts in proportion to the increase of the load applied on the bottom plate 3 to change the inclination angle of the bottom plate 3. It will be. The bottom plate pushing-up means 4 is not limited to the gas spring as shown in the figure, but may be simply a coil spring.

The hopper 5 to be housed in the frame 2 is made of a flexible sheet such as various kinds of cloth or synthetic resin, and is formed in a rectangular tube shape having an upper surface opened and to be housed in the frame 2. A cylindrical discharge port 8 is provided in the.

The hopper 5 has a vertical dimension such that when the upper end is fixed to the upper bar 9 of the frame 2, the lower part of the hopper 5 rests on the bottom plate 3 in a horizontal state. This enables the bottom plate 3 to be tilted upward.

The upper end of the hopper 5 is fixed to the upper rail 9 of the frame 2 by folding the upper peripheral wall of the hopper 5 housed in the frame 2 outward along the upper rail 9 and overlapping the inner and outer portions of the peripheral wall with each other. It is performed by sewing.

It should be noted that the discharge port 8 is formed at a lower position on the front surface side of the peripheral wall of the hopper 5 in a cylindrical shape protruding outward using a flexible material, and this cylindrical portion is formed by a string or a band. Although the example in which it can be opened and closed by tying it up is shown, the discharge port 8 may have a structure that can be opened and closed with a fastener or the like.

Further, the frame 2 is not limited to the cylindrical frame shape as shown in the drawing, but may be formed in a cylindrical shape with at least the upper surface and the front surface opened, and the hopper 5 has the upper half portion of the peripheral wall made of a metal plate or a composite material. It may be formed of a resin plate and the lower portion may be made of a flexible material.

The transport container of the present invention has the above-described structure, and when the container 1 is placed on a truck or the like and the cereal is not loaded into the hopper 5, as shown in FIG. 2 (A), The bottom plate 3 has an inclined shape in which the tip thereof is pushed up by the pushing-up means 4, and the lower portion of the peripheral wall of the hopper 5 is compressed.

When the grain A is put into the hopper 5 as shown in FIG. 2B with the discharge port 8 closed, the weight of the grain A increases and the bottom plate pushing-up means 4 contracts, so that the bottom plate 3 Lie down on Supira.

When the bottom plate 3 is horizontally laid down, the hopper 5 has the maximum internal volume.

When discharging the grains stored in the hopper 5, the discharge port 8 may be opened as shown in FIG. 2C, and the grain A inside may flow out from the discharge port 8 to the outside. As the amount of cereal A in the hopper 5 decreases due to the outflow, the load acting on the bottom plate lifting means 4 also decreases, and the means 4 gradually expands and lifts the bottom plate 3, and the bottom plate 3 lifts. 6 is tilted upwards and the lower part of the hopper 5 is pushed up in an inclined manner, so that the grains in the hopper 5 are surely discharged toward the discharge port 8 located on the downward slope side, and the whole amount is discharged. It will be.

[0022]

[Effect of device]

 As described above, according to this invention, the bottom plate is attached to the lower part of the frame so that it can swing up and down, and the bottom plate push-up means is provided between the bottom plate and the frame. Since the lower part is pushed up by the bottom plate, the lower part of the hopper becomes horizontal due to the increase in the input amount of cereals, and the storage capacity of the hopper can be maximally ensured. Rotates upward to make the lower part of the hopper inclined, so that the entire amount of grains stored in the hopper can be reliably discharged without using special external power or human power.
