Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a raw material weighing hopper for weighing raw materials for various plants.

[Conventional technology]

A conventional raw material weighing hopper will be explained with reference to FIGS. 6 to 8.

The hopper main body 1 has a funnel-shaped lower part, and a discharge gate 2 is provided at the lower end. Further, the hopper main body 1 is placed on the frame 4 via a weighing device 3,
The raw material stored in the hopper body is weighed by a weighing device 3. The hopper main body 1 is simply placed on the frame 4 via a weighing device 3, and must be supported by another support mechanism in case of horizontal forces generated by earthquakes or wind.

In the conventional support mechanism, a reinforcing ring 5 having a T-shaped cross section is attached to the inner surface (or outer surface) of the hopper main body 11, and a horizontal force supporting metal fitting 6 is attached at a required position on the outer surface of the position where the reinforcing ring 5 is attached. Horizontal force is supported through the support hardware 6.

In the figure, numeral 7 indicates a stone box for preventing raw material from directly colliding with the lower part of the hopper body, and 8 indicates a beam for supporting the stone box.

[Problem that the invention attempts to solve]

In the conventional raw material weighing hopper described above, the reinforcing ring must have a heavy structure in order to have the strength to withstand horizontal force, the reinforcing ring and the stone box are installed separately, which increases the weight, and the installation of the reinforcing ring Because it is welded to the hopper body all around,
Large deformations occur due to welding distortion, and many man-hours are required to correct this deformation.

[Means for solving problems]

The present invention constructs a hopper deformation prevention beam by spanning a beam on the same plane in the vertical direction of the hopper body placed on a weighing device, and installs horizontal force supporting hardware at the outer surface position of the fixed end of the beam. The horizontal force can be supported through the mounting hardware.

[Effect]

The strength member receiving the horizontal force is a beam structure instead of a ring shape as in the conventional case, and the structure is extremely simple and lightweight. Further, since the beam and the hopper body are welded only to the end faces of the beam, there are significantly fewer welding locations, welding distortion is reduced, and manufacturing is easy.

〔Example〕

A first embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

Components in the drawings that are the same as those shown in FIGS. 6 to 8 are designated by the same reference numerals.

A cross-shaped hopper deformation prevention beam 9 is installed at a predetermined position in the vertical direction of the hopper main body 1.
Attach the horizontal force support hardware 6 to the outer surface of the hopper body 1 in alignment with the four end fixing positions. Further, a stone box 7 is provided at the center of the deformation prevention beam 9, and a wear-resistant liner 10 is pasted on the upper surface of the prevention beam 9.

In the above configuration, when a horizontal force acts on the hopper body 1, the axial force generated in the deformation prevention beam 9 is transmitted to the frame, building, etc. via the horizontal force support hardware 6 and supported.

As a result, the reinforcing ring 5 and the beam 8 supporting the stone box 7 are not required, making it simple and lightweight and easy to manufacture.

Note that FIG. 3 shows another embodiment in which the deformation prevention beam 9 has a three-pronged shape, and the one shown in FIG. 4 has the deformation prevention beam 9 in a triangular shape. Furthermore, instead of attaching the wear-resistant liner 10 to the upper surface of the deformation-preventing beam 9, the material may be accumulated as shown in FIG. 5, so that a self-lining effect can be achieved. Furthermore, a deformation prevention beam may be used instead of the conventional reinforcing ring, and the stone box may be supported by the beam below the deformation prevention beam.

[Effect of idea]

As described above, according to the present invention, (i) the strength member for preventing deformation of the hopper body is changed from the conventional ring shape to a beam shape, resulting in a light structure and easy manufacturing; (ii) hopper deformation The installation capacitance of the prevention beam is very small compared to the conventional one, so the deformation of the hopper body due to welding is significantly reduced, and there is no need to repair deformation, making manufacturing easier. (iii) Stone boxing of the hopper deformation prevention beam When used as a supporting material, it can exhibit excellent effects such as reducing the amount of material and reducing weight.
