Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention manufactures a building material made of natural stone, in particular, a material called a random sticking stone plate by finishing a corner of a stone piece after cutting a standard stone plate. The present invention relates to an apparatus for performing the above.

[Prior art] At present, granite is mainly used for building materials that are generally used for building materials.
Although it is widely used for walls and the like, it has not been efficient since the stones have been chamfered one by one using a cutter or sander, and the size has been limited to 80 to 200 mm.

[Problems to be solved by the invention]

As mentioned above, random sticking stone slabs are chamfered using cut pieces of stone after cutting standard stone slabs from natural stone, but conventionally, each piece is finished using a cutter or sander, so efficiency is high. But the cost was high.
For example, it is traded at 10,000 yen near per 1m ² in the small, 1m ² per 4,000 of the tile (100 × 100 size ones)
It is much more expensive than a yen.

In the present invention, by processing in a mass production manner, for example,
Even at 2,000 yen per 1m ² it is intended to provide an apparatus for producing profitable.

[Means for solving the problem]

As means for achieving the above object, the manufacturing apparatus of the present invention has the following configuration.

(1) A rotating drum having a regular octagonal cross section, a large number of protrusions arranged on the inner surface in a staggered manner, and a noise prevention plate of one or two layers stretched on the outer periphery via a porous material such as styrene foam. Partly has a material input / output port, so that the rotation speed of the rotary drum is around 20 rotations per minute, so that the stone material put inside spreads forward with the rotation of the drum over the reverse one Make it flow.

(Operation)

The manufacturing apparatus of the present invention, when the temporary to 1 m ² per 2,000 turbulent bonded slate (sold currently in 9,500 yen) and can be supplied, per 1 m ² in the certain trading catalog 25,00
The construction cost of 0 yen is broken down as follows.

Laborer fare 4,000 yen (20,000 yen ÷ 5) sand, cement costs 1,000 yen turbulent stuck slate 2,000 yen profit 18,000 yen (1m per ²⁾ 90,000 yen (per person laborer) On the other hand the turbulent pasting slate costs, material costs ( transportation Hikomi) 5,000 yen / t personnel costs 6,429 yen (15,000 yen ÷ 7 × 3) energy costs and amortization 571 yen total 12,000 yen Now that the turbulent stuck slate of 1t per 10m ² can take the sales fee is 2,000 × 10 = 20,000 yen, 8,000 for 3 hours operation
Yen (20,000 yen-12,000 yen), 34,000 turns, 24,000 per day
The profit of the yen will be 600,000 yen on the 25th of January operation, and a great profit can be expected on both the manufacturing side and the construction side.

〔Example〕

FIG. 1 is a partially cut front view showing an embodiment of the present invention, and FIG. 2 is a partially cut side view of the same.

1 is a 3.75 kW motor or 5 hp engine, 2 is a drive gear on the motor side, 3 is a drive chain, 4 is a center shaft, 5 is a drive gear of the drum 6, 7 is a round protrusion on the inner surface of the drum 6, 8 Is a loading / unloading lid for the drum 6, 9 is a lid stopper stay, 10 is a drive safety case plate, 11 is a tightening bolt, 12 is a leg frame, 13 is a frame auxiliary plate, 13
Is a frame base, 15 is a bearing, 16 and 17 are noise prevention plates, and 18 is a polystyrene foam material.

The drum 6 is a regular octagon and both ends are narrowed.
One is supported by a bearing 15, and the other is driven and rotated by a motor or an engine 1 via a drive gear 5, a drive chain 3, and a motor-side drive gear 2. Reference numeral 8 denotes a charging / discharging lid provided on a part of the drum 6, which can be opened and closed by a lid stopping stay 9. Reference numeral 7 denotes a round protrusion on the inner surface of the drum 6, and many are arranged in a staggered manner.

When the material is thrown in from the lid 8 and driven and rotated at 20 revolutions per minute, the advancing material flows so as to spread without falling onto the reversing material, and one course is completed approximately every three hours, and 1t ( 10m ² min) can be processed.

〔The invention's effect〕

According to the present invention, what has been conventionally processed one by one can be processed in a large amount at a time, and a great benefit can be brought about on the manufacturing side and also on the construction side.
