Abstract

PURPOSE:To provide processed garden stones with special lust and tint by allowing fine particles such as muddy sand, soil, etc. to give smooth appearance to the exposed defoliation on the surface of each material stone to be processed, and thereby imparting the same appearance as weathered by water stream for years to the stones. CONSTITUTION:Material stones for garden landscaping get rid of sharp angles and protrusions unsutable for the purpose and undergo inspection to know where they have texture, foreign matters, cracks or brittle parts to possibly cause defoliation, and then gravel, steel balls and grit with a comparatively large dia. are blasted together with high-pressure water to these defective parts, followed by honing, to tear off all defoliable parts, cut away the foreign matters and bore the brittle parts in a comparatively short while. The resultant stones will be also provided with properly worn ridges. Thereafter muddy sand, soil, etc. is blasted to give smooth appearance to the exposed defoliation on the surface of the stones ground and polished. Thus the surface of the resultant stones will have the same appearance as weathered by water stream for years.

Description

[Detailed Description of the Invention] This invention involves honing a raw stone with a crushed surface, etc. using 4 yen of different shot materials,
In a relatively short period of time, it has the same appearance, shape, and skin quality as if it had been washed by river flow for many years.

By the way, it is believed that stones play an important role in promoting the aesthetic sense of gardens in both the East and the West. It's a good thing. In particular, the i4A used is required to have a more natural shape, appearance, and color tone in order to harmonize with the garden being created. Securing lumber suitable for use in gardens has been a particularly important issue.

For this purpose, a 1m IW has been constructed based on the shape, appearance, or color tone of the stone that has been secured, and with a separate plan for stonework that will take advantage of the effects of the stone that has been provided. be.

A. The method for processing garden stones according to the invention takes into account the inconveniences in conventional garden creation, and provides a method for creating gardens by artificially providing stones with a shape, appearance, or color tone suitable for garden creation. The stonework was made to match the ideal, making it possible to create a garden full of aesthetic appeal in line with the design.

Gardens with naturally warm stones, such as those seen in ri1, kare111 suisei-gumi, etc., are relatively easy to adapt to the structure of Japanese houses and lifestyles.
As expected, this has led to the problem of depletion of natural resources and the destruction of nature.

The method of processing garden stones according to the present invention makes up for the shortage in the supply of natural materials and actively provides garden stones of natural flow, thereby effectively stopping the destruction of nature due to overexploitation. It is intended to do something.

4Ff In the garden stone processing method according to the present invention, the honing process is carried out in an extremely short time by using shot materials such as steel balls and sand and mud in accordance with the properties of the raw stone to be processed. Furthermore, it has been made possible to effectively provide early-born field stones exhibiting the intended appearance and skin quality.

In order to achieve the desired effect in the method for processing garden stones according to the present invention, in particular, the outline of the structure is explained using steel balls, steel clicks, etc. - Shot material with a relatively large diameter such as gravel and sand and mud are projected sequentially or simultaneously with high-pressure water to grind the weak cell composition part of the raw stone to be processed and to peel off the separated composition part and harden it. In terms of polishing and polishing the composition ridges and surfaces, the following communal examples and those for which considerable design changes were planned (with respect to these examples) It is.

A typical example of the garden stone processing method according to the present invention will be explained below. In any case, the fXI, which is considered particularly harmful for use as a garden plant, is cut by 1 minute, and then the part where separation or peeling is clearly recognized is forcibly removed. This was then taken into a liquid honing facility.

In this liquid honing liquid film, there is a device for collecting the gravel, steel balls, steel glycide, or sand and mud used for shot, and a device for collecting the gravel, steel balls, steel grid, or sand and mud used in the shot. A conveying device that transports the gravel, steel balls, steel glycide, or sand and mud together with ground or crushed stone chips to the hominog section, and a high-pressure water mixing device that separately uses the conveyed gravel, steel balls, steel glycide, or sand, and the ground or crushed stone chips for separate use. It consists of a device that projects the supplied high-use water onto the raw stone to be processed,
Various types of equipment are determined depending on the degree of rough stone processing and processing capacity.

Especially for grinding and crushing gravel, steel balls, steel grids, etc.! g A rockless treatment process and a finishing process with sand and mud are separately configured, and equipment for collecting, transporting and projecting coarse shot materials such as gravel, steel balls or steel grids, and collecting, transporting and discharging sand and mud. It was planned that a separate projection device would be provided.

In addition, it is easy to carry the raw stone into and out of the t1, and the rotation of the support base of the raw stone is easy. In this case, a turntable is prepared in the center of the device, which is surrounded by a partition wall, and a steel ball or steel grid is placed on the rough stone placed on the turntable from a throwing MJ++ placed at the top of the device. This method involves projecting ground or crushed stone chips or sand and mud together with pressurized water, and regulating the rotation of the table in accordance with this projecting.

In addition, in cases where the raw ore to be pressurized has a particularly large weight and it is difficult to drive the table or it is not easy to carry it in and out of the chamber, If it is necessary to particularly increase the force, in step 9, prepare multiple throwing QJ devices without rotating the raw stone to be processed, and slightly sprinkle 4Qr44+=1 on these projection devices. By projecting the stone, it was possible to hone the stone evenly over the entire circumference of the stone.

In addition, a 1iij device is installed to sort stone chips that have been peeled or ground from the pressurized raw stone and remove especially coarse stone lumps, or conversely, a sieve device and a storage mass are installed to remove sand and mud generated as needed. Installation force < 51 + 1 cold preset.

Also, in the case of λ in the honing part, there are cases in which steel for shot, grund, sand, mud, etc. are dropped into the combined pressure horn water of 1, and in case of injection pressure water. When projecting sand and mud or other shot or honed materials while suctioning them from the supply section of the shot or honing materials using negative pressure, other equivalent methods are planned. It is something.

Me, collected steel balls, steel glint, stone, sand, mud)
As the conveying device, there are a number of common conveyance devices, such as a conveyor lift, a conveyor lift, a net conveyor, a shooter, a vacuum shooter, and other devices.

, the steel ball that is used in the river is I / \ and 1 steel ball')
・The diameter of the head is 5 to 6 IIlff1 or more, ideally 8 m.
The composition state of the stone in the wave force U machining rough stone, which is classified as a large shaft member with a diameter of 4+j or more than m or less, and the hardness of the steel is 1", especially Grinding uXi
11. Harder than the stone composition to be polished. Softer strength than the basic stone composition in Tsukata 11/
) It is ideal to select and use it within the range.

Furthermore, the gravel to be used in the river is relatively coarse, and various t, '+' of 1, % are added to the coarse grain of about 15 mm from the J1 area of fine gravel, that is, sand, which has been successively fine-grained during circulation use. t
'J'? It uses a mixture of human gravel and includes a part that functions as a grinder, crusher, or digger, and a part that functions as a polisher and polisher.

In addition, the sand and mud used must be sand or smaller in particle size.
It has a stone part and a soil part, and is applied to the raw stone under pressure as a material that corresponds to the abrasive material.It creates a unique polish on the surface of the raw stone to be processed, and also gives the processed surface a fine finish. It is designed to impart a particularly nice texture to the raw stone to be processed.

In addition, the pressurized water used for projection will not only be prepared and provided by an appropriate pressurizing pump, but also will be prepared by blowing high-pressure air, and will be approximately 50 kg/cm" or more.
Ideally, the pressure water should be 100 kg/cm2 or more or F-rated.

Under Article 1, first, sharp edges or protrusions that are unsuitable for use as garden stone materials are removed using an air hammer, etc., and then carried into the projection device section and placed in the pressurized rough stone. Check the grains of the stone, parts with different compositions, cracks that will become peeling surfaces, and parts with a weak composition '9, and apply honing to each of these parts by adjusting the projection angle to suit peeling, cutting, and digging. It has been subjected to

As a result, relatively large-diameter gravel, steel balls, and steel grindstones can be used to strip off the peelable parts of the rough stone, cut parts with different compositions, and dig into parts with weakly porous compositions in a relatively short time. It is designed to reduce the wear of the stone ridges to an appropriate level.

Also, along with the projection of this gravel or steel balls, steel grinders,..., crushed debris,! By simultaneously projecting stone chips, which are IJ cuttings, onto the raw stone to be processed, the surface of the raw stone is made to have a smooth surface with a smooth texture, creating a unique, especially natural flow 6-like surface. It is what was done.

In Europe, by projecting the sand and mud simultaneously with or following the projection of the gravel, steel balls, or steel glyphs 1, a unique precise roundness is created on the surface of the ground and polished raw stone. This gives the pressed rough stone the same kind of shine as if it had been washed with a stream of water over many years.

As described in ``Description'', the method according to the present invention involves a process of projecting steel balls, steel glint, or gravel with a relatively coarse flow diameter onto a workpiece rough stone through honing treatment without using a shot or blasting method. By using the method of ejecting particularly fine sand and mud, a concrete effect of the above-mentioned characteristics is expected.

When gravel is used in the process of processing rough materials that are scheduled for grinding, polishing, etc., a more natural boulder-like surface is obtained; When used as a steel grid, the following additional features were observed. In other words, when steel balls or steel grids are used under certain conditions, compared to the conventional method in which gravel, etc. is vaguely projected onto the workpiece material, there is less chance of flaking off from the intentional part, and of different compositions. It is possible to cut and remove parts or make holes in areas with weak cell composition, and
By presupposing intentional operations, rough stone processing can be accomplished in an extremely short period of time and with high efficiency.

In particular, in Karucho J:, the drilling of holes, which had been considered impossible in previous precedents, was made into a 13J function, and the creation of thin stones in Karesansui stonework, etc. was also made into an Ofo function. .

In addition, in the Karu-r method, crushed or cut stone chips are mixed in as 11n-order shonto material during processing of the raw stone, but these stone chips are rapidly crushed and turned into dust. This is said to have the effect of creating a fine texture on the surface of the raw stone being processed, and as it becomes even finer, it gradually flows out, and the amount of stone debris that occupies the raw stone is always within a certain number ff+. , no influence on the grinding or polishing effect of the steel ball or steel grid was observed.

Next, in polishing the surface with sand and mud,
Because polishing is done using extremely fine particles such as muddy sand and mud, the exposed peeling surface on the surface of the rough stone during grinding and polishing becomes a smooth surface, and it can withstand water flow for many years. J-tai-ishi is a stone that has been washed to give it a rough texture and has a luster and color tone that cannot be seen in rough stone processing using gravel, steel balls, steel grids, etc. This makes it possible to provide this service.

The processing method according to the present invention promises to provide processed garden stones that closely resemble natural rough stones within a relatively short period of time and without producing any noise or dust. It is.
