Field of the Invention The present invention relates to a stone processing device for cutting or polishing stones inside a frame structure, and more particularly to a device for blocking and preventing the scattering of dust scattered from a processing portion. .

Description of the Related Art For example, a stone material processing apparatus for cutting a large stone plate from a rough stone is usually constructed by providing a processing portion inside a frame structure. In the processing section, a rough stone is installed at the bottom of the frame structure, and a large number of cutting blades are applied to the rough stone,
Water containing iron sand, slaked lime, and cutting stone powder is sprayed from the water sprinkler to the cutting site, and the cutting blade is reciprocally driven substantially horizontally to cut the rough stone.

われている。これに対し、架構体の上面は、面積が大き
く、散水器等の配管を含む各種機器も設置されているの
で、シート類の張設が困難である。At the time of cutting, the steam containing dust rises from the processed portion due to the frictional heat accompanying the cutting. Therefore, in the conventional stone material processing apparatus, the side surface of the frame structure is covered with a sheet or a panel so that dust is not scattered to the outside of the frame structure. On the other hand, since the upper surface of the frame structure has a large area and various devices including pipes such as sprinklers are also installed, it is difficult to stretch the sheets.

ため、同様に頻繁な清掃が必要であって、メンテナンス
に手間がかかるものである。Even if the sheets are stretched, and if the sheets are transparent, the sheets are immediately contaminated by dust and the inside of the frame structure cannot be confirmed. That is, since this type of device is extremely large, it is necessary to perform it from the top of the device in order to visually confirm the processed portion. Further, if an attempt is made to install a dust collecting device for absorbing dust, the structure becomes large and complicated, resulting in high cost. In addition, the dust collector needs to have a large power, and the power consumption is enormous. Moreover, it is necessary to frequently replace the filter, and in addition, since the inside of the duct of the dust collecting device is immediately clogged, similarly frequent cleaning is required and maintenance is troublesome.
【０００５】こうした理由から、従来は、架構体の上面

点があった。Therefore, according to the conventional stone processing apparatus, dust-proof measures are insufficient, and water vapor containing dust is scattered from the upper surface of the frame to the outside, and the dust is always in a floating state. However, there is a problem that the surroundings of the device are contaminated.
【０００７】そこで、本発明の課題は、簡単かつ安価な

し、本発明を完成したものである。In general, an air curtain is constructed by vertically blowing air down to form a blocking wall. The present inventor tried to apply this air curtain to the above dust blocking, and as a result of various trial studies, as a result of forming the air curtain laterally in the upper part of the stone processing device, blocking water vapor containing dust and cooling it. The present invention has been completed by discovering that it can be made into water droplets and can be made to settle under dust with dust.

It is designed so that it does not go outside. On the blocking plate 32 on the side opposite to the blower 16, an oblique guide plate 26 for guiding the air flow blown from the air outlets 18 is provided across the entire width above the blocking plate 32. The material of the guide plate 26 may be an iron plate or any material similar thereto. The guide plate 26 is formed so as to project 40 to 60 cm inward of the frame structure 1 and is provided such that the upper end edge thereof is located about 20 cm below the air outlet 18. There is.

The vertical length of 7 is approximately 1.5 m. The side leakage prevention sheet 27 prevents side leakage of the air flow, prevents turbulence of the air flow, and prevents the inflow of outside air. Therefore, this sheet 2
The periphery of the formation portion of the air curtain 30 is closed by 7 and the closing plate 32.

Then, as the fan 17 rotates, the air is blown out from the air outlet 18 in a lateral direction slightly downward, and an air curtain 30 is formed above the processing portion 4 by the air flow. At this time, since the guide plate 26 guides the air flow forming the air curtain 30 downward, on the side of the closing plate 32 facing the blower 16, the air flow is not disturbed and the flow becomes smooth. Therefore, the side leakage prevention sheet 27 and the closing plate 3
The air curtain 30 can be reliably formed over the entire region above the processed portion 4 surrounded by 2.

Therefore, the blower 1 is installed in the corner of the frame structure 1.
It is possible to effectively prevent scattering of dust from the upper surface of the frame structure 1 with a simple and inexpensive structure in which only the 6 is installed. Therefore, dust contamination around the processing device can be prevented.

The air flow is guided in the direction of the arrow in FIG.
Naturally discharged from below. At this time, the water vapor containing the dust introduced in the direction of the arrow along with the air flow is sprayed from the water sprinkler 6, so that the water vapor is cooled. Therefore, the dust contained in the water vapor is wet-collected naturally without being discharged to the outside of the apparatus.

い。Further, unlike the dust collector described above, it does not suck in dust, so cleaning of the filter is not necessary and maintenance is free. Further, since the air curtain 30 does not obstruct the visual observation, the cutting processing portion 4 can be visually checked at all times, and unlike the case of covering the sheets, it does not become invisible due to dirt due to dust.
