The transmission case can realize right-angle transmission through common mechanisms such as bevel gears or cardan shafts.

The angle adjusting component can be realized in various ways, and the simplest way is to use mutually matched turntables with pin holes, and to position the angle adjusting by adjusting the angles of the turntables and using different pin holes. Of course, the angle can be adjusted by driving the hydraulic rotary support or the explosion-proof motor. Two ways of installing the saw blade are needed because intersecting gaps are opened on the roadway stone wall, and the stone wall is drawn into small units which are not connected with each other, as shown in fig. 8.

The free end of forearm 33 articulates mounting bracket 53, mounting bracket 53 includes two connecting rods, the relative forearm bilateral symmetry of connecting rod sets up, its one end is articulated with 33, the other end is fixed one rather than the perpendicular horizontal board, when mounting bracket 53 rotated directional forearm 33 front end, horizontal board contactless saw bit 42, fixed a plurality of hydraulic hammers 51 on the horizontal board, it makes hydraulic hammer 51 can rotate and angle modulation relatively horizontal board through the angle modulation part is articulated between hydraulic hammer and the horizontal board, one side sliding connection scraper blade 52 of hydraulic hammer 51 is kept away from to the horizontal board, scraper blade 52 can the reciprocal anchorage relatively horizontal board.

The diameter of the saw blade 42 is between 30-50cm, the thickness of the saw blade is in the range of 3-5mm, and the power of the hydraulic hammer can be smaller.

A grooving process, comprising the steps of:

1) cutting a plurality of parallel gaps on the slotting surface by using a saw blade, wherein the depth of the gaps is within the range of 5-15cm, and the width of the gaps is within the range of 3-5 mm;

2) cutting a gap intersected with the gap in the step 1) on the slotting surface by using a saw blade, wherein the intersected angle is in the range of 70-90 degrees;

3) crushing the stones formed in the second step by using a hydraulic hammer;

4) using a scraper to collect crushed stones and discharging the crushed stones out of the groove;

5) and (4) repeating the steps 1-4 until the slotting reaches the expected depth.

With the above apparatus and grooving process, firstly, the power of the apparatus can be relatively small, because the steps 1-4 are actually to open a shallow groove and divide the crushing step into crushing small stones, which has low requirements on the size of the saw blade, the power of the hydraulic motor and the output power of the hydraulic hammer, so that the cost is reduced and the maintenance cost is also greatly reduced; the grooving efficiency is improved, complex work is divided into 3-5 simple works, the work efficiency is not linear improvement in practice but exponential improvement, the reason is that when the grooving is carried out, no matter what equipment is used, the surface part is easy to remove, but when the grooving is carried out to a deep part, the difficulty is increased, the efficiency is greatly reduced, the grooving work is changed into the grooving always carried out on the surface by the equipment and the process, and the work efficiency can be greatly improved. And the former equipment needs the artifical broken stone piece of removing ceaselessly, and this operating time is very consuming in the aspect of, and the degree of difficulty is very big, especially when the groove is very deep, and the manual work is exempted from the operation. Finally, the equipment and the process have the advantages that the raised dust is little, the slotted surface is divided into small blocks, the small blocks are broken and separated from the slotted surface, the generated dust is very little, the safety coefficient is high, and the working environment is healthier and more environment-friendly.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and those skilled in the art can make various modifications and variations. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
