DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a granular raw material forming machine used for forming a block or the like from a kneaded product of a granular raw material such as sewage slag and an inorganic binder.

[0002]

2. Description of the Related Art The present inventor is developing a slide hopper type molding machine as a molding machine for molding a sidewalk block or the like from a kneaded material of the above-mentioned granular raw material and an inorganic binder. As shown in FIG. 2, the molding machine includes a slide hopper 3 reciprocated by a cylinder 4 along the table surface 1. At a position where the slide hopper 3 is retracted, a granular material is supplied from a material supply hopper 5 installed above the slide hopper 3. At the position where the slide hopper 3 has moved forward, and the granular raw material is charged into the molding die 2 installed below the table surface 1. The basic structure of this molding machine has already been applied for a patent as Japanese Patent Application No. 2-200199.

[0003] When a block body is molded by such a molding machine, it is often desired to use a colored granular material having a fine particle size for the surface layer and a coarse granular material having no color for the back layer. . Therefore, in the molding machine shown in FIG. 2, the raw material supply hoppers 5 are arranged on both sides of the molding die 2, and each raw material supply hopper 5 is filled with granular raw materials having different colors and particle sizes. By alternately moving the slide hoppers 3 installed below, two types of granular raw materials were supplied into the mold 2.

However, in a molding machine of the type in which the granular raw material is supplied from the raw material supply hopper 5 as shown in FIG. 2, when the color of the surface layer is changed, the granular raw material remaining inside the raw material supply hopper 5 is changed. Must be discharged and replaced with a new granular raw material, and since the granular raw material has high tackiness, there is a problem that this color changing operation requires much trouble.

[0005]

SUMMARY OF THE INVENTION The present invention has been completed to solve the above-mentioned conventional problems and to provide a granular raw material molding machine capable of easily performing a color changing operation.

[0006]

SUMMARY OF THE INVENTION The above problem is, above the double
Each of the lower granular material from the material supply hopper of a few
In particulate material molding machine for performing molding by introducing into the mold in through slide hopper which is provided, wherein the raw material supply hopper
The inside of at least one raw material supply hopper is vertically divided into a plurality of sections, and each section is filled with granular raw materials having different colors and particle sizes, and a slide gate having an opening is aligned below each section. It said slide along the supply port was
The opening is communicated with any one of the supply ports by slidably moving the slide gate, and the other supply port is closed, while the other supply port is closed. Of granular raw material from two compartments through the slide hopper
The problem can be solved by a granular raw material molding machine characterized in that it can be put into a mold.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in more detail with reference to the illustrated embodiments. FIG. 1 shows an embodiment of the present invention.
Is a table surface, 2 is a molding die installed below the table surface 1, 3 is a slide hopper reciprocated by the cylinder 4 along the table surface 1, and 5 is installed above a position where the slide hopper 3 is retracted. a raw material supply hopper, the above structure is similar to the molding machine shown in FIG. 2.
However, the inside of the raw material supply hopper 5 is divided into three sections in the vertical direction as shown in the figure, and each section can be filled with granular raw materials having different colors and particle sizes. Further, a slide gate 6 made of a perforated plate having an opening is provided slidably along the lower surface of the aligned supply port below each section of the raw material supply hopper 5. To slide the opening to communicate with any one of the supply ports, and to close the supply ports of the other sections while transferring the granular raw material of a specific section to the slide hopper 3.
Can be selectively supplied to

[0008]

In the granular raw material molding machine thus configured, any kind of granular raw material can be supplied to the slide hopper 3 only by sliding and moving the slide gate 6, and the slide hopper 3 is imagined. The granular raw material can be introduced into the mold 2 by moving forward as indicated by the line. Thereafter, the granular raw material for the back layer is charged by the slide hopper 3 on the opposite side shown in FIG. 2, and then the upper layer 9 shown in FIG. Can be obtained. Therefore, there is an advantage that the color of the surface layer can be changed simply by moving the slide gate 6.

[0009]

As is apparent from the above description of the embodiment, in the present invention, a small number of hoppers for supplying a plurality of raw materials are used.
Is divided into a plurality partitioning the inside of one Kutomo longitudinally, upon being filled with different particulate material in color and particle size in each compartment, by removing any particulate material through only Sula Idohoppa moving the sliding gate, A granular raw material molding machine capable of easily performing a color changing operation can be provided. Therefore, the present invention greatly contributes to industrial development as a granular raw material molding machine that has eliminated the conventional problems.
