Field of the Invention The present invention relates to an apparatus for finishing an aggregate such as a seed stone mixed in a cement concrete block so as to be exposed on the surface. More specifically, the present invention relates to a cast molding, a press molding, a vibration molding, and the like.

た。2. Description of the Related Art Unhardened concrete mixtures on a block surface have conventionally been removed and cleaned by a manual or electric wet brushing treatment using a wire brush, a synthetic resin brush, or an animal or vegetable fiber brush. In addition to the wet brushing, the uncured cement mixture has been removed by subjecting the block surface to a treatment with an inorganic acid such as hydrochloric acid or by applying a high-pressure water jet treatment.

めて不経済であるという問題があった。The wet brushing process is greatly affected by the material and shape of the brush, and the effect differs depending on the degree of contact between the block surface and the tip of the brush.
There was a problem that the brush was not effective in spite of large damage. The treatment with inorganic acids has safety and hygiene problems such as generation of harmful gas and scattering of the cleaning solution. There is always a part with little delay effect on the surface part of the block subjected to delay treatment that is very close to the surface layer, but if it is tried to completely wash that part by high-pressure water jet treatment, it will not be possible for other parts with sufficient delay effect There was a problem that the water pressure and water volume became excessive, wasteful and extremely uneconomical.

り、ブラシの消費量は極めて少ない。The cement concrete block in which the cement setting speed of the surface layer is delayed by the retarder has an uncured surface of the cement mixture. The uncured surface is placed on a device such as a conveyor that conveys at a constant speed with the uncured surface facing upward. At the entrance side of the transfer device, while the brushing device supplies a certain amount of water, the synthetic resin brush containing annular abrasive grains planted on one side of the rotating disk is rotated at a relatively low peripheral speed to abut against the block surface, The very near surface portion of the cement mixture after the delayed treatment of the cement is washed away.
Due to variations in the drying conditions during the curing period, there are some parts of the block surface that have little delay effect, but brushing will wash thin parts that are very close to the surface regardless of the delay effect, but high-pressure water will delay the effect. It is not easy to wash away the parts with little water. In this brushing cleaning, the consumption of the brush is extremely small due to the combination of the contact with the extremely thin portion of the block, the relatively low peripheral speed, and the brush made of synthetic resin containing abrasive grains.

としての品質が安定する。A disk-shaped centrifugal plate having a diameter smaller than the inner diameter of the brush concentrically planted on one side of the rotating circular base is mounted in parallel with the disk so as to maintain a constant gap. Almost all of the supplied water flows directly to the brush by the centrifugal force caused by rotation. As a result, effective brushing is achieved with a smaller amount of water. In this brushing process, the concrete block whose thin part extremely close to the surface layer has been washed away is washed away by a washing device that sprays high-pressure water immediately after this process, so that all unhardened cement mixture that has not been washed away is exposed. Finish quality is stable.

産性の高い骨材露出仕上の自動化装置となる。[0008] The high pressure water spray cleaning is effective when the spray angle is set to 45 to 70 ° with respect to the processing surface exposing the aggregate of the block. Since the cleaning power is inversely proportional to the injection distance from the tip of the injection nozzle to the block, a plurality of nozzles are installed in the high-pressure head to secure a constant injection distance and a cleaning width of the block. The interlocking control of the above-described device results in an economical and highly-productive automated aggregate exposure finisher.

美しい外観を持つ。As shown in FIG. 6, when four flat nozzles 21 are attached to a horizontally extending high-pressure water head 20 per block width of 60 cm, the entire block width can be uniformly cleaned. In FIG. 1, the conveyor 3 runs at a speed of 2 m / min in the direction of the arrow. When the concrete block 30 on which the retarder treatment has been performed is placed at the entrance with the treated surface facing upward, the unwashed surface 31 of the surface is first subjected to the wet brushing treatment of the brushing apparatus 1. The entire amount of water is supplied to the centrifugal plate 14 through the water supply passage 13 of the rotary pipe 12, and is supplied from the gap 15 to the brush 11 by centrifugal force. Therefore, effective brushing is performed with a small amount of water. Since the brush 11 comes into contact with a very thin portion of the block surface and rotates at a relatively low peripheral speed, the consumption of the brush is small. By this brushing, the surface of the concrete block very close to the surface layer becomes the brush surface 32 in a state where it is washed away regardless of the delay effect. This brush surface 32 is subjected to a high-pressure water jet treatment by the next cleaning device 2, where it becomes a finished surface 33 from which the uncured cement mixture has been washed away. The uncured cement mixture can be easily removed by high pressure water injection,
High water pressure injection equipment with relatively low water pressure and low discharge rate can be used. The finished surface 33 has a beautiful appearance in which the seed stones are raised on the surface.

持費が大幅に低減するという優れた効果を奏する。As described above, in the apparatus of the present invention, a thin portion near the surface layer of a cement concrete block treated with a retardant is washed away by a wet brush treatment irrespective of the retardant effect, and then unwashed by a high-pressure water jet treatment. By washing away the hardened cement mixture, only the advantages of each treatment are taken in, so the brush life is much longer than that of the conventional wet brushing only, compared to that of only the high pressure water injection treatment In addition, since the pressure of the high-pressure water is low and the amount of water is small, an excellent effect that the equipment cost and the maintenance cost are significantly reduced is exhibited.
