As shown in FIG. 4, the vacuum chamber 12 of the first housing 10 has a relatively smaller radius than the softening chamber 11 to increase the dust collecting performance. Vacuum pressure is generated through the partition plate 121 As shown in Fig.

This structure has a structure in which the area of the vacuum chamber 12 is gradually reduced as compared with the combustion chamber 11 so that the dust collection performance can be increased.

The partition plate 121 is composed of a lower plate 121a for sealing the lower surface of the vacuum chamber 12 and a vertical plate 121b bent upward from the lower plate 121a to partition the polishing chamber 11, (12) are individually sealed so that a vacuum pressure can be generated.

At this time, a plurality of cutting grooves 121c are formed at predetermined intervals in the bent portions of the lower plate 121a and the vertical plate 121b, so that the dust generated in the polishing chamber 11 can be collected by the vacuum pressure .

A connecting pipe 122 communicating with the vacuum chamber 12 is coupled to the upper end of the first housing 10. The connecting pipe 122 may be connected to a vacuum pump (not shown).

That is, the upper disk 31 and the lower disk 32 of the rotating unit 30 are pressed against the support plate 13 by the pressing bolts 33 passing through the grooves 131, The upper disk 31 and the lower disk 32 are rotated by the length of the grooves 131 depending on whether the disk is fastened or not.

A guide bracket 40 for guiding a handle rod 41 having a handle 411 in a vertical direction is fixed to the upper surface of the pivoting means 30.

The guide bracket 40 rotates together with the pivoting means 30 and also functions to allow the grip 411 to be folded.

One side of the second housing 50 is integrally coupled to the lower portion of the guide bracket 40 and the other side of the second housing 50 is connected to the shaft 60 to which the traveling wheel 61 is connected through two arms 51 to be.

Here, since the second housing 50 is coupled to the guide bracket 40, the second housing 50 can be rotated together with the rotation of the rotation unit 30.

Accordingly, the first housing 10 and the second housing 50 can vary the angle between the first housing 10 and the second housing 50 through the rotating unit 30, thereby providing a structure capable of continuously traveling in the traveling direction as well as in the straight direction .

On the other hand, the arms 51 are hinged to both sides of the second housing 50 in the form of "┏". At this time, the lower portion of each arm 51 is coupled to the shaft 60 so that the second housing 50 can be driven while rolling on the ground, and the height of the second housing 50 can be varied with respect to the shaft 60.

The second housing 50 is fixed by the horizontal adjusting means 70 connected to the central portion of the shaft 60.

The horizontal adjusting means 70 functions to adjust the height of the second housing 50 with respect to the shaft 60 according to the inclination of the workpiece surface or the horizontal degree of the polishing pad 25. [

The horizontal adjustment means 70 includes a rotation lever 71 exposed at an upper portion of the other side of the second housing 50 and a bearing connected to the rotation lever 71 and fixed to the inside of the second housing 50 A hollow shaft 73 coupled to the hollow shaft 73 and freely rotatable with respect to the hollow shaft 73 so as to be coupled to the hollow shaft 73, And an upper portion of which is hinged to the screw shaft 74 and the lower portion of which is fixed to the shaft 60.

That is, according to the above structure, the rotation lever 71 is grasped by the hand according to the inclination of the workpiece surface or the polishing pad 25 to rotate the hollow shaft 73 clockwise or counterclockwise, thereby rotating the second housing 50 ) Can be raised and lowered from the ground, and a detailed description thereof will be described below.

In the lower portion of the first housing 10, a scattering prevention curtain 14 is further coupled to prevent scattering of dust generated by the polishing pad 25.

Hereinafter, the operation of each part of the concrete grinding apparatus according to the present invention will be briefly described.

FIG. 7 is an operation diagram showing a second housing which rotates through the rotation means, and FIG. 8 is an operation diagram showing a second housing which is height-adjusted through the horizontal adjustment means in FIG.

As shown in FIG. 7, the first housing 10 and the second housing 50 can change the angle between the first housing 10 and the second housing 50 via the rotating unit 30.

 Referring to FIG. 3, the second housing 50 is fixed to the guide bracket 40, and the guide bracket 40 is fixed to the upper disk 31 of the rotating unit 30.

The support plate 13 is constrained by the pressing force of the upper disk 31 and the lower disk 32. [

In this state, when the pressing bolt 33 is unfastened, the pressing force of the upper disk 31 and the lower disk 32, which press the upper and lower portions of the supporting plate 13, weakens and the restraint of the supporting plate 13 is released.

The supporting plate 13 whose restraint is released is changed to a desired angle and then the pressing bolt 33 is tightened so that the traveling direction can be continuously traveled not only straight but also in the curved direction.

Also, the pressure bolt 33 can be loosely tightened to allow the first housing 10 to freely travel by steering the first housing 10 in a desired direction with respect to the second housing 50.

Here, the second housing 50 is configured such that the height of the second housing 50 can be varied in the shaft 60 by the pair of arms 51 and the interlocking arm 75.

The second housing 50 is fixed to the screw shaft 74 hinged to the interlocking arm 75 by the hollow shaft 73 of the horizontal adjusting means 70, But remains fixed.

On the other hand, when only one side of the polishing pad 25 is in close contact with the surface of the workpiece, the rotation lever 71 is held by hand to rotate the hollow shaft 73 clockwise to lower the hollow shaft 73. The second housing 50 coupled to the hollow shaft 73 is lowered with respect to the shaft 60 so that the polishing pad 25 can be leveled.

Conversely, when only the other part of the polishing pad 25 is in close contact with the workpiece surface, the hollow shaft 73 is rotated in the counterclockwise direction through the rotation lever 71 to rotate the second housing 50 relative to the screw shaft 74 As a result, the second housing 50 can be raised with respect to the shaft 60 to which the traveling wheels 61 are coupled, thereby aligning the polishing pad 25 in level.

9 is a configuration diagram showing another example partitioning plate.

9, the partitioning plate 121 for partitioning the vacuum chamber 12 has a curved surface having an inner diameter relatively larger than a rotation radius of the polishing pad 25, And a plurality of cutting grooves 121c inclined at a turning radius are formed.

This structure prevents the centrifugal force of dust corresponding to the rotation of the polishing pad 25 from being interfered with the partitioning plate 121 and also forms the cutout groove 121c in the direction of rotation of the dust to reduce the speed of the rotating dust So that it is possible to collect dust.

This structure has the effect of reducing the energy because the dust can be easily collected even if the vacuum pressure is weak.

It is to be understood that the invention is not limited to the disclosed embodiment, but is capable of many modifications and variations within the scope of the appended claims. It is self-evident.
