Description

DETAILED DESCRIPTION OF THE INVENTION

TECHNICAL FIELD [0001] The present invention belongs to the technical field related to grain containers for transportation.

2. Description of the Related Art Conventionally, a support frame 1 is mounted on a carrier such as a truck, and the support frame 1 is fixed on the carrier with a rope or the like, and an opening made of a flexible material is formed in the support frame 1. There is known a transporting grain container in which the upper four corners of the closing sheet member 2 and the upper four corners of the cereal storage bag 3 are suspended and held via connecting means of only elastic strips 4 and 5, respectively. I have. Then, the empty cereal container is mounted on a transport vehicle and travels to the field, and the cereal harvested and harvested in the field is stored in the cereal storage bag 3. When released, this sheet member 2 closes the upper opening of the grain storage bag 3. The grain container in this state is transported to a farmhouse or a common workshop, and then the elastic strip 5 and the grain storage bag 3 are disconnected, and then the grains are discharged and collected to a required location by using a crane operation or the like. (See FIGS. 6 and 7)

[0003]

[0005] The prior arts described above include a vehicle such as a truck which starts and stops, more specifically, a shock at the time of sudden start or sudden stop or an impact inertia of a sudden brake during traveling. When the grain storage bag filled with grains whose upper part is supported only by the elastic strip tilts, and the tilt causes the elastic strip to exceed the allowable set elongation length, the tilted grain storage bag may not automatically return. If the heavy cereal storage bag remains tilted as described above, the weight balance of the transport vehicle will be disrupted, and driving will be hindered. So the driver stopped the car,
Complicated work such as manually returning the collapse of the grain storage bag to a normal state is required, and this is not preferable in terms of work efficiency. In addition, if the elastic strip and the grain storage bag are disconnected during transportation or the elastic strip is cut, the support means and the grain storage bag are connected only by the elastic strip. As a result, the cargo collapse may occur, and a sudden accident caused by the collapse of the cargo may be induced.

SUMMARY OF THE INVENTION An object of the present invention is to restrict the inclination of a grain storage bag generated by an impact action during transportation to within an allowable setting range of an elastic strip, and the inclination is automatically restored by an elastic restoring action of the elastic strip. It is to provide a grain container.

An object of the present invention is to provide a cereal storage bag made of a flexible material whose upper end is openable and closable in a support frame mountable on a carrier such as a truck, and at least an upper portion of the cereal storage bag. In the transporting grain container in which the four corners are suspended and held on the support frame via the elastic strips, the elastic strips are provided with a flexible cord that is shorter than the allowable set elongation length and has no extensibility. Along the side, it is achieved by restricting the amount of elongation of the elastic strip within the allowable setting range.

[0007] The object of the present invention is to connect the base end of the flexible cord to the upper end of a support bearing for supporting the handle for attaching and detaching the elastic cord to and from the grain storage bag. It is achieved by doing.
