According to the present invention, the edges of each side connected at right angles to the corners of the corners protrudingly so that the sidewalk blocks for paving the ground of a garden, sidewalk or park, and the bricks for the construction of the building have a natural aesthetic appearance. The present invention relates to a polishing device for blocks and bricks for smoothly rounding parts, and more particularly, to a water-filled inside of the barrel body sealed at both ends of a polygonal barrel such as a hexagon or an octagon. Blocks and bricks are polished in the filled state so that they can collide smoothly between blocks and bricks during the grinding process to minimize the failure rate such as breakage. Edges of blocks and bricks on each of the liners As a means of forming a plurality of polishing holes vertically and horizontally in order to promote the ball, it is possible to shorten the polishing processing time of blocks and bricks, and after finishing the polishing process, lift one side of the barrel body to one side. The present invention relates to a polishing apparatus for rotating a barrel body in an inclined angle so as to smoothly pull out blocks and bricks in which polishing has been completed.

Generally, the sidewalk block paving the ground or the brick building construction is manufactured in the shape of a cuboid, and since the sidewalk block or the brick is artificially manufactured by a molding frame, it cannot express a natural aesthetic effect, and the shape of the rectangular shape The corners are protruding, and each edge connecting each side is protruded at right angles, so that corners or household seats can be easily broken during impact, so when the sidewalk blocks or bricks collide with each other during transportation, There is a problem that corners or edges are easily broken or cracks occur, resulting in difficulty in maintaining the original shape as in the time of manufacture of the sidewalk blocks and bricks. The edge or the If you suffer an accident inflicted injury by Lee portion it has been often occur.

Therefore, in view of the various points as described above, as a conventional technology to have a natural aesthetic appearance by roundly grinding the corners and home seats of sidewalk blocks or bricks made of rectangular parallelepiped bar has been proposed as Utility Model Registration No. 20-175061 have.

The prior art has a structure in which the barrel body, which is open at both sides of one side of the inlet and the other side of the outlet, is fixedly installed at an inclined angle, but the one side of the inlet is installed in a high state and the other side of the outlet is installed in a low state, thereby rotating as a motor. When the furnace rotates the barrel body while supplying the sidewalk block or brick while supplying water, the introduced sidewalk blocks or bricks are wetted by the water flowing along the inclined barrel body and ascend to a certain height along the direction of rotation of the barrel body. It is an operation that wears in contact with the inner surface of the barrel body while rolling in and out of an irregular shape, so that each corner and each edge can be roundly polished.

However, since the conventional technology configured as described above has water supplied to the inlet of the barrel body fixedly installed inclined and continues to flow along the sloped inner surface, the sidewalk blocks or bricks put into the barrel body are wetted with water, but the barrel body As a result of rising by a certain height in the direction of rotation and falling down by its own weight, it moves downwards and is discharged to the outlet. As such, the sidewalk blocks and bricks that are rotated to the upper side by the rotational operation of the barrel body are lowered by their own weight. There was a problem that the failure rate was increased due to the crash falling up, and the defect rate was increased. Also, to solve such a problem, the sidewalk block and the brick inserted into the inlet while rotating the barrel body at a very slow rotational speed (10-20 rpm) were used. The number of grinding processes to discharge to the outlet If you will be repeated two or more times, the defective rate will be reduced to some extent but the polishing time becomes longer and the productivity is lowered consumption of electric energy has been pointed out as a problem that it becomes more.

In addition, the above-described prior art has a problem that the inner surface of the barrel body wears due to the friction between the sidewalk block and the wall, thereby shortening the service life of the barrel body.

Therefore, the present invention is to solve all the problems appearing in the prior art as described above, the object of the present invention is to seal the both ends and the inside of the barrel body after the appropriate number of sidewalk blocks or bricks in the barrel body Filling the water higher than the blocks or bricks put into the grinding process to increase the movement of the barrel body, the blocks and bricks falling by the weight falls to the water to reduce the impact to minimize the failure rate, For other purposes, it is possible to extend the service life of the barrel body by attaching a plurality of liners of a certain size to the inner surface of the barrel body, and to polish the edges of blocks and bricks on each liner prefabricated to the inner surface of the barrel body. Vertical and horizontal grinding holes to promote In order to shorten the polishing time by means of the above, another object is to make the polishing process while the barrel body is fixed horizontally when intermittently polishing blocks or bricks by appropriate quantity. In order to continuously carry out the polishing operation is to invent the polishing factory to raise the one side of the barrel body to a certain height to fix the barrel body inclined at a predetermined angle in one direction to proceed the polishing process continuously.

Figure 2 is an operating state of the present invention shown in the cross-sectional view AA line of Figure 1, Figure 3 is a perspective view of a liner mounted inside the barrel body of the present invention, Figure 4 is a cross-sectional view of one embodiment of the lifting device of the present invention, Figure 5 shows an operational state diagram in which one side of the barrel body is inclined at a predetermined angle with a lifting device to take out the blocks and bricks polished from the barrel body of the present invention or to perform continuous polishing.

In the drawing, reference numeral 1 denotes a barrel body, and the barrel body 1 is octagonal in order to be able to drop blocks or bricks to be polished during rotational operation to a certain height in a rotational direction and then drop them to their own weight. Or it is formed in polygonal cross-sectional structure, such as a hexagon.

The barrel body 1 is fixed in a state inclined at a horizontal state or a predetermined angle on the base 2 is installed to polish the block or brick by the rotation operation.

To this end, the fixed bracket 21 protruding on one side of the base 2 has a rotary bracket 31 protruding downward from the bottom of one side of the support frame 3 rotatably supporting the barrel body 1. It is rotatably coupled, the support 22 is projected to a certain height upwardly installed on the upper surface of the opposite side (2) of the fixing bracket 21, the support 22 is The support bracket (3) rotatably installed by the fixing bracket (21) of the base (2) is responsible for the function of fixing in a horizontal state.

The buffer member 23 is attached to the upper end of the support 22, and the buffer member 23 is horizontal in a state in which the support frame 3 is inclined with the hinge axis of the fixing bracket 21 as the rotational starting point. The rollers are rotated downward (counterclockwise when viewed in the drawing) to mitigate impact when they come in contact with the upper end of the support 22.

In addition, the support bracket 24 fixedly attached to the upper surface of the other side of the base 2 to which the support 22 is attached is lifted upward so that the barrel body 1 is inclined to one side or horizontally. A lifting device 4 for lowering is rotatably attached.

The elevating device 4 is provided with an electric motor 41 as shown in Figs. 2 and 4, and is engaged with the worm shaft 42, which is the output shaft of the electric motor 41, rotates in place. The worm wheel 43 is inserted into the female screw hole formed in the center of the worm wheel 43, and the worm wheel 43 moves up and down while operating in a reverse direction. ) Is provided with a lifting rod 44 which rotates up and down using the hinge side of the fixing bracket 21 as a starting point.

On the other hand, the connecting member 32 fixedly attached to the bottom of one side of the support frame 3 is supported in a state that allows the insertion of the elevating rod 44 of the elevating device 4.

Support rollers 5 are mounted on both sides of the upper surface of the support frame 3 so as to be rotatable on the brackets, and the support rollers 5 are rotatably protruded annularly on both outer peripheries of the barrel body 1. An accommodating groove 51 supporting the state in which the 11 is rotatably fitted is formed. Accordingly, even when the barrel body 1 is inclined to one side, the barrel body 1 can be rotated without slipping in the inclined direction.

The main motor 6 for rotating the barrel body 1 is installed in the motor support frame 33 protruding downward in a state of being fixedly attached to the support frame 3 to the support frame 33. It is supposed to move as follows. That is, when the support frame 3 rotates in the up and down direction by the lifting operation of the lifting rod 44 installed in the lifting device 4, the main motor 6 is also in the up and down direction. Will move.

And the barrel body (1) is configured to rotate by receiving a rotational force from the main motor (6), the structure for transmitting the rotational force of the main motor (6) using a pulley and belt or a chain gear and chain Although a pulley and a belt are used in this invention, it uses as an Example. That is, the drive pulley 61 of the main motor 6 is connected to the drive pulley 61 mounted on the output shaft of the main motor 6 and the interlocking pulley 12 installed on the outer periphery of the barrel body 1 by the belt 62. The rotational force of is transmitted to the interlocking pulley 12 through the belt 62 is configured to rotate the barrel body (1).

On the other hand, in the present invention, in order to be able to grind blocks or bricks in a state filled with water in the barrel body 1, the flanges formed on both sides of the front and rear ends of the barrel body 1 in a trapezoidal shape. The front and rear cylinders 7a and 7b are screwed together and bolted together, and then the front and rear cylinders 7a and 7b are opened and closed as bolts in each of the inlet 71a and outlet 71b of the front and rear cylinders 7a and 7b. The plates 72a and 72b were detachably screwed together so as to be sealed or opened.

Gaskets and packings (not shown) are interposed between both ends of the barrel body 1 screwed as bolts and each of the front and rear cylinders 7a and 7b, and the front and rear cylinders 7a and 7b. Even when the inlet 71a and the outlet 71b are sealed, the front and rear opening / closing plates 72a and 72b are screwed in the state of sandwiching the gasket or the packing. Therefore, the water is not leaked when the block or brick is polished in the state in which the barrel body 1 is filled with water, thereby enabling the grinding process to proceed efficiently.

And one side of the rear cylinder (7b) is equipped with a water supply and drain valve (8a) for supplying or draining water in the barrel body (1), and the other side to discharge the water stored in the barrel body (1) Air valve (8b) is installed so that the discharge of water is made well by allowing the outside to flow in when making.

In addition, in the present invention, when the water stored in the barrel body (1) is discharged to the water supply and drain valve (8a) after completing the grinding process of blocks and bricks, the water that is locked to the bottom of the barrel body (1) is completely discharged. When the barrel or the block body 1 is inclined to one side and continuously blocks or bricks, the water continuously supplied from the inlet 71a side can be continuously discharged. To this end, a plurality of drain valves 8c are provided, and each of the drain valves 8c has a rear cylinder 7b or a rear end of the barrel body 1 to which the rear cylinder is screwed at a predetermined interval. The plurality of drain valves 8c are mounted to be positioned at angled portions where the surfaces of the barrel body 1 meet each other to transfer water supplied to the barrel body 1. The amount was discharged.

A plurality of liners 9 are attached to the entire inner surface of the barrel body 1 to prevent abrasion, and each of the liners 2 is formed on each inner surface of an octagonal or hexagonal shape as shown in FIG. 2. The main body 1 is attached to the longitudinal direction (or the axial direction) in the form of a tightly spaced apart.

Each of the liners 9 is detachably attached by bolts (not shown), and each of the liners 9 has a plurality of polishing holes 91 for grinding corners of blocks or bricks. It is formed by a plurality of rows.

In addition, a noise preventing plate 92 made of a rubber-based material is interposed between the inner surface of the balal body 1 and each of the liners 9.

Referring to the operation of the present invention configured as described above are as follows.

In order to grind the blocks or bricks to be polished to an appropriate number, the elevating device 4 is operated so that the barrel body 1 is in a horizontal state as shown in FIG. 1, so that water can be easily supplied. After the water supply and drain valve 8a is positioned upward, only the front opening and closing plate 72a is disassembled from the front cylinder 7a of the barrel body 1, or the front and rear cylinders 7a and 7b are moved forward. In a state where the rear opening and closing plates 72a and 72b are dismantled, an appropriate number of blocks or bricks are introduced through the inlet 71a of the front cylinder 7a and the outlet 71b of the rear cylinder 7b.

After the block or brick is added as described above, the front and rear open / close boards 72a and 72b are screwed into the respective inlets and outlets of the front and rear cylinders 7a and 7b, and then for drainage. Water is supplied to the barrel body 1 by connecting a water supply hose (not shown) to the valve 8a. The amount of water supplied at this time may be such that blocks or bricks introduced into the barrel body 1 can be completely locked. For example, as shown in FIG. 2, the supply is made so that at least half of the barrel body 1 is filled, and then the water supply and drain valve 8a is closed and the water supply hose is dismantled.

When the main motor 6 is driven in a state in which the barrel body 1 is filled with blocks or bricks and water, the barrel body 1 rotates at a very slow speed (10 to 20 rpm). Since the main body 1 has an octagonal or hexagonal cross-sectional structure, when the barrel body 1 rotates, the blocks or bricks move in a rotational direction along each inner surface, and each liner (from the water stored in the barrel body 1) 9) the edges and the edges are polished by frictional contact, and the blocks and bricks frictionally contacted with the liner 9 are rotated to a higher position than those stacked thereon, and then gravity In this case, blocks or bricks dropped after being moved up to a predetermined height fall in the water in the water filled in the barrel body (1). Because the falling speed is slow, so that the impact of the bricks at the bottom of the relief does not wake up by a drop impact it is possible to minimize the defects of the screen polished compared with the prior art.

In addition, the blocks and bricks to be polished as described above are not moved to either the front cylinder 7a or the rear cylinder 7b of the barrel body 1, but are simply moved in the rotational direction of the barrel body 1 in the inserted position. After being raised to an appropriate height, the operation of dropping in water to its own weight is repeated. A plurality of polishing holes 91 formed in each of the liners 9 attached to the inner surface of the barrel body 1 are formed of blocks and By intensively polishing each corner of the bricks, it is possible to shorten the time that the corners are roundly polished, thereby shortening the polishing time of the block or brick.

When the polishing process of the block or brick is completed by the above-described polishing operation, first, the main motor 6 is driven only for a short time, and the barrel body 1 is rotated halfway. Stopping the barrel body 1 with 8a) located at the lower side, and then connecting the drain hose (not shown) to the water supply and drain valve 8a and opening the valve to open the water stored in the barrel body 1. In this case, when the air valve 8b formed on the opposite side to the water supply / exhaust valve 8a is opened, external air flows in as much as the amount of water discharged to the water supply valve 8a. It is possible to shorten the discharge time of water, and when the barrel body 1 is discharged in a horizontal state, water at a height lower than that of the water supply and drain valve 8a is left without being discharged.

Therefore, when the water remaining in the barrel body 1 is discharged, and the block or brick is to be withdrawn, the lifting rod 44 of the elevator 4 is lifted to operate the barrel body 1 as shown in FIG. In addition, the inclined to one side, and only the drain valve (8c) located in the lower side of the plurality of drain valve (8c) to operate to discharge the remaining water, and then to remove the block or brick is completed In this case, when the main body 6 is driven in a state in which the discharge hose is released from the water supply and drain valve 8a and the barrel body 1 is rotated to one side, the blocks or bricks move in the rotational direction. At the same time to move toward the inclined direction is discharged through the outlet 71b of the rear cylinder (7b),

On the other hand, the barrel body (1) can be connected to a plurality of long and the block and brick grinding process, in this case, front and rear inlet and outlet 71a and outlet 71b of the front and rear cylinders (7a) (7b) The inlet 71a of the front cylinder 7a is rotated and operated by the said barrel body 1 in the state which disassembled the opening-closing board 72a, 72b, and opened all the several drain valve 8c. Continuous supply of water to the block and the brick to be continuously processed at the same time when the continuous operation of the barrel body (1) that is rotated to be supplied to the water flow continuously to the floor, and the continuously injected blocks or bricks to the flowing water Wetting is performed by frictional contact with each liner 9, in which case a plurality of polishing holes 91 formed in each liner 9 not only facilitates the polishing of the edges of blocks or bricks, but also the liner 9. Are located on the floor When it is flowing, it contains flowing water, and when it is moved upward from the bottom by an angle, it pours out the contained water.

Therefore, at the bottom of the barrel body 1 rotating in an inclined state to one side, the impact of the block and the bricks is blurred by the amount larger than the amount flowing by the water supplied from the inlet 71a. It can be alleviated to reduce the defective rate of the abrasive products.

On the other hand, in the present invention, the lifting device 4 for operating the horizontal body and the inclination of the ball body (1) has a structure for lifting and lowering the lifting rod 44 by the rotational power of the electric motor 41 as an embodiment However, the elevating device 4 may be constituted by a hydraulic cylinder or the like.

According to the present invention as described above it is possible to improve the polishing efficiency of rounding the corners and edges of the sidewalk block or brick round, especially when limited to a small number of blocks to block the brick body horizontal It is operated in the state and sealed at both ends so as to fill the water into the amount that can infiltrate the injected products and to carry out the polishing process to reduce the gravity action by the weight of the blocks and bricks, and also to reduce the impact shock between the blocks and the bricks. It can be alleviated, so that each corner or edge can be smoothly polished without breakage, or when the blocks and bricks are to be continuously polished, the barrel body is rotated to one side and rotated. The effect is to make the grinding process proceed, In addition, the liner attached to the inner surface of the barrel body not only extends the service life of the barrel body, but also the polishing holes formed in the liner facilitate the polishing of the edges of the blocks and bricks, thereby reducing the grinding time. Provide effect.
