That is, a pair of cutting blades 132 of one configuration of the cutting means 130 is mounted to the front end of the subframe 114 by the pin 131 so as to be rotated up and down angularly, side by side in the left and right directions Arranged and mounted.

In addition, as another configuration of the cutting means 130, the rotary shaft 133 is mounted to the rear end of the subframe 114 so as to rotate, and the upper surface of each cutting blade 132 and the outer diameter surface of the rotary shaft 133 is predetermined The position is integrally connected by the connecting rod 134, the angular rotation operation bar 135 is integrally connected to one side end of the rotary shaft 133.

Accordingly, when the angular rotation operation bar 135 is rotated forward, the rotation shaft 133 rotates forward at the same angle, and the connecting rod 134 integrated with the rotation shaft 133 is also at the same angle. Each turn is made.

In other words, the connecting rod 134 integrally with the upper outer diameter surface of the rotating shaft 133 is positioned at the lower outer diameter surface of the rotating shaft 133 according to the forward angular rotation of the rotating shaft 133, and thus, the connecting rod 134. As the height of the connection rod 134 is lowered.

At the same time, the pair of cutting blades 132 integrated with the front end of the connecting rod 134 is also lowered to lower the height, the cutting edge of each cutting blade 132 is press-fitted in the joint groove 200 It is done.

As can be seen in Figure 4, the guide means 140 is mounted to extend in the forward direction from the side of the subframe 114, the means for pre-transporting along the joint groove 200 in which the waste sealing material 202 is embedded As, the concrete pavement of the present invention serves to guide the path when the sealing material removal apparatus moves forward.

In one configuration of the guide means 140, the long bolt 141 is mounted at a predetermined position on the side of the subframe 114, the end of the long bolt 141, the handle for rotating the long bolt 141 ( 142 is mounted.

In addition, the long bolt 141 is inserted into the rear end of the guide rod 143 is rotatably hinged, the front end of the guide rod 143 extends long toward the front, especially the front end of the guide rod 143 A guide wheel 144 seated in the groove 200 and performing a rolling motion is mounted.

In this case, when the long bolt 141 is moved forward or backward by rotating the handle 142, the left and right positions of the guide rod 143 inserted into the long bolt 141 are adjusted and mounted on the guide rod 143. The left and right positions of the guide wheel 144 are adjusted, so that the position between the guide wheel 144 and the joint groove 200 can be aligned in a line.

Therefore, when the engine unit 112 is driven, the rotational power by the gear train 117 and the chain 118 is transmitted to the traveling wheel 102 mounted on the lower base 100, the concrete pavement road of the present invention When the sealing material removing device is to be moved forward, the guide wheel 144 of the guide means 140, as described above for the concrete pavement sealing device of the present invention while moving forward rolling motion in the joint groove (200) You will be guided forward path.

That is, since the guide wheel 144 and the joint groove 200 of the guide means 140 are aligned in line as described above, the joint groove in the state where the guide wheel 144 is correctly inserted and seated in the joint groove 200. The cloud movement along the 200 will guide the forward movement path for the concrete pavement sealing material removal apparatus of the present invention.

In this way, the forward movement guide operation of the guide means 140 is made, and the cutting means 130 coming along the rear of the guide means 140 makes an operation to cut the side surface of the closed sealing material 200 in the joint groove 200. do.

More specifically, in the state in which each cutting blade 132 of the cutting means 130 is pushed down to the both side wall surface of the joint groove 200 as described above, according to the drive of the engine unit 112 as described above the present invention When the advance of the sealing material removing device of the concrete pavement of the made, as shown in Figure 8 attached to each cutting edge 132 also advances along the joint groove 200 of the waste sealing material 200 in the joint groove 200 Both sides are cut, and both sides of the waste sealing material 200 are separated from both side walls of the joint groove 200.

Next, after both sides of the waste sealing material 200 are separated from both side wall surfaces of the joint groove 200 by the cutting means, the waste sealing material 202 in the joint groove 200 by the waste sealing material removing means 150. Is lifted and removed completely.

To this end, waste sealing material removal means 150 for scraping and lifting the waste sealing material 202 cut by the cutting means on both sides of the joint groove 200 is removed at each bottom surface of the lower base 100. It is rotatably mounted.

Looking at the configuration of the waste sealing material removal means 150, as can be seen in Figure 5, the support rod 152 is rotatably inserted into the hollow body 151 formed integrally on both sides of the bottom surface of the lower base 100, The central portion of the support rod 152 is integrally formed with a hook 154 to scrape off the cut waste sealing material 202 in the joint groove 200, and also to fix and release the position of the support rod 152 and the hook 154. In order to fasten the bolt 153 to tighten the outer surface of the support rod 152 through the hollow body 151 is fastened.

Therefore, the fastening bolt 153, which is fastened to the hollow body 151 and fastening the outer diameter surface of the support bar 152, is released, and then the support bar 152 is rotated downwardly, and at the same time the support bar 152 The hook 154 integrally formed at the center portion is also rotated downward to be inserted into the joint groove 200, and then tightens the fastening bolt 153 again, thereby inserting the hook inserted into the joint groove 200. A firm fixed state of 154 is achieved.

Accordingly, the rotational power of the engine unit 112 is continuously transmitted to the traveling wheel 102 mounted on the lower base 100 by the gear train 117 and the chain 118, thereby sealing the concrete pavement of the present invention. Since the removal device continues to move forward, the hook 154 of the waste sealing material removing means 150 scrapes the bottom of the waste sealing material 202 in the joint groove 200 and lifts it as shown in FIG. 9. As a result, the waste sealing material 202 in the joint groove 200 is completely separated and removed by the waste sealing material removing means 150.

At this time, even if the waste sealing material 202 in the joint groove 200 is completely separated by the cutting means 130 and the waste sealing material removing means 150, the inner wall surface of the joint groove 200 is in a very rough state. Since it remains difficult to reinsert the new sealing material, it also interferes with the construction of the new sealing material in good quality.

To this end, it is necessary to grind the inner wall surface of the joint groove 200 evenly so that a new sealing material can be inserted smoothly, and thus the joint groove 200 is connected to the connection frame 116 integrally connected to the rear end of the chassis frame 110. Grinding means 160 for uniformly grinding the inside of the) is installed.

As can be seen in Figure 6, the grinding means 160 is a means for uniformly grinding the wall surface in the joint groove 200 in which the waste sealing material 202 is removed by receiving the power of the engine unit 112, the chassis frame It is intensively mounted on the connecting frame 116 integrally connected to the rear end of the (110).

As a configuration for driving the grinding means 160, a pair of grinding wheels 162 connected by the engine unit 112, the gear train 117, and the chain 118 are rotatable in the connection frame 116. And a pair of grinding wheels 162 are arranged side by side back and forth.

At this time, the gear train 117, the chain 118, and the pair of grinding wheels 162 are wrapped and covered by the cover body 161.

Therefore, as shown in FIG. 10, after the waste sealing material 202 in the joint groove 200 is removed by the hook 154 of the waste sealing material removing unit 150, the joint groove in which the waste sealing material 202 is removed is removed. A pair of grinding wheels 162 grind the wall in 200.

That is, in the state where the sealing material removing device of the concrete pavement of the present invention continues to move slowly forward, the rotational power of the engine unit 112 is a pair of grinding wheels 162 by the gear train 117 and the chain 118. The pair of grinding wheels 162 cleanly grind the wall surface of the joint groove 200 in which the waste sealing material 202 is removed while the grinding wheel 162 is rotated at the same time.

Meanwhile, when the grinding wheels 162 of the grinding means 160 do not coincide with the joint groove 200, the left and right positions of the chassis frame 110 are adjusted using the chassis frame left and right conveying means 120. By doing so, the connecting frame 116 integrally mounted to the chassis frame 110, the grooves 200 jointed with the left and right positions of the grinding wheels 162 of the grinding means 160 mounted to the connecting frame 116 and The position can be adjusted to match.

As shown in FIG. 3, the chassis frame left and right conveying means 120 not only adjusts the left and right positions of the chassis frame 110, but also functions to assemble the chassis frame 110 and the lower base 100 to each other. To this end, a transfer hole 121 is formed on the upper surface of the lower base 100 along the width direction, and the transfer pipe 122 mounted along the width direction on the bottom surface of the chassis frame 110 in the transfer hole 121. By inserting the transferable, the relative coupling between the lower base 100 and the chassis frame 110 is made.

In this case, as another configuration of the chassis frame left and right conveying means 120, a screw hole 123 is formed at a predetermined position on the bottom surface of the chassis frame 110, and the screw bar 127 rotates in place in the screw hole 123. Is inserted, and the driven bevel gear 124 is formed at the outer end of the screw bar 127, and the driven bevel gear 124 is formed at the lower end of the vertical rotary operation bar 126 at the driven bevel gear 124. ) Is meshed.

Therefore, in order to adjust the left and right positions of the chassis frame, first rotating the rotation operation bar 126 of the chassis frame left and right conveying means 120 to one side, the driving bevel gear 125 of the rotation operation bar 126 is rotated At the same time, the driven bevel gear 124 is engaged and rotated, so that the screw bar 127 rotates in place in the screw hole 127 formed on the bottom of the chassis frame 110, and eventually the screw bar 127 As the in-situ rotation, the chassis frame 110 in which the screw holes 127 are formed moves finely to the left or the right.

With the left and right movement of the chassis frame 110 as described above, the connecting frame 116 integrated with the chassis frame 110 and the grinding means 160 mounted on the connecting frame 116 are also moved to the same position. Therefore, since the position of each grinding wheel 162 of the grinding means 160 can be easily adjusted to a position corresponding to the joint groove 200.

Thus, by using the chassis frame left and right conveying means 120, by aligning the front and rear position between the grinding wheel 162 and the joint groove 200 of the grinding means 160, the grinding wheel 162 of the grinding means 160 always This will precisely grind the wall in the joint groove 200.

On the other hand, as the grinding wheel 162 grinds the wall of the waste sealing material 202 removed by the waste sealing material removing means 150 and the joint groove 200 from which the waste sealing material 202 has been removed, including the waste sealing material. Since concrete powder may be scattered and scattered to the outside, a cleaning means for directly removing the suction is required.

To this end, primary cleaning means 170 for suctioning and removing foreign matters that are ground by the waste sealing material and the grinding means removed in the joint groove 200 are provided.

1 and 2, as one configuration of the primary cleaning means 170, the suction pipe 172 serving as a suction discharge passage of the waste sealing material and the grind foreign matter is the cover body 161 of the grinding means 160. The suction compressor 171, which is mounted on the upper side and is a suction driving source, is installed at a predetermined position of the chassis frame 110.

At this time, the storage tank 174 for storing the inhaled waste sealing material and the ground foreign matter is mounted at a predetermined position of the chassis frame 110, the suction compressor 171 and the suction pipe 172 is attached to the suction hose 173. Are interconnected.

Therefore, due to the suction force according to the driving of the suction compressor 171, the waste sealing material 202 removed in the joint groove 200 and concrete powder generated when grinding the wall surface in the joint groove 200, etc. By passing through the 172 and the suction hose 173 to the storage tank 174 to be stored, it provides an environmentally friendly surface that can prevent the waste sealing material and concrete powder to be scattered to the outside.

Thus, even after the waste sealing material 202 and the concrete powder and the like are removed by suction, residual foreign substances such as fine powder may remain in the joint groove 200, so that the inner space of the joint groove 200 may be reconstructed to construct a new sealing material. It is preferable to clean again.

To this end, in order to finally suck in and remove the foreign matter remaining in the joint groove 200, the secondary cleaning means 180 is installed at the rear end of the grinding means 160.

As shown in FIG. 7, the secondary cleaning means 180 is connected to the back of the cover body 161 of the grinding means 160 and has a skeleton structure 182 having wheels 181 on the bottom thereof to travel thereafter. Based.

In addition, a motor 183 is mounted to the rear of the skeletal structure 182, and a brush 184 for floating the foreign matter remaining in the joint groove 200 is connected to the shaft of the motor 183, and the skeletal structure ( At the rear of the motor 183, a small air compressor 185 is mounted on the side of the motor 183 to finally clean the inside of the joint groove 200 by blowing foreign matter caused by the brush 184 into the air.

Therefore, as shown in FIG. 11, as the motor 183 is driven and the brush 184 rotates in the joint groove 200, the joint groove 200 is driven by the rotational force of the brush 184. Foreign matter remaining in the inside (such as fine concrete powder) is injured.

At the same time, when air is blown from the nozzle connected to the small air compressor by the operation of the small air compressor 185, the fine concrete powder injured in the joint groove 200 is blown out of the joint groove 200 and removed. As a result, the inside of the joint groove 200 is maintained in a clean state in order to construct a new sealing material.
