[0034] In the scheme designed by the present invention, by synchronously rotating the handles 56 on the left and right outer walls of the shell 1, the adjusting screw 54 can be rotated in the adjusting nut 55, and then the transmission shaft 45 will be driven to slide out or retract in the transmission shaft tube 41 through the rotating sleeve 53, the support strip 52 and the support sleeve 51, thereby facilitating the symmetrical transmission shaft tubes 41 to slide away from or close to each other, and then facilitating the removal or installation of the two cutting discs 3 from the cutting chamber 11 or into the cutting chamber 11.

[0035] As an embodiment of the present invention, the adjustment and installation assembly 6 includes a connecting rod 61, a threaded rod 62, a limit strip 63, a positioning sleeve 64, an inner ring 65, a positioning plug 66, a locking nut 67 and a square plug 68. The two ends of the connecting rod 61 are respectively provided with a threaded rod 62, and at least four limit strips 63 are installed in a circumferential array on the outer ring surface of the connecting rod 61. The outer ring surface of the connecting rod 61 is sleeved with a positioning sleeve 64, and the length of the positioning sleeve 64 is adjusted according to the distance between the two cutting discs 3.

The cutting discs 3 sleeved on the threaded rods 62 are locked and fixed by locking nuts 67. The two square blocks 68 are respectively fixed to the end surfaces of the two threaded rods 62, and each square block 68 is respectively slidably inserted into each square slot 452.

[0036] In the solution designed by the present invention, when the distance between the two cutting discs 3 needs to be increased, the locking nut 67 is first disassembled from the threaded rod 62, and then the inner ring 65 on the cutting disc 3 is removed from the threaded rod 62, and then the positioning sleeve 64 is removed from the connecting rod 61, and then the positioning sleeve 64 of the required length is sleeved on the connecting rod 61, and at this time, the limiting strip 63 on the connecting rod 61 will slide into the limiting long groove 641, so that the positioning sleeve 64 can be located in the middle position of the connecting rod 61, and then The cutting disc 3 is sleeved on the threaded rod 62 through the inner ring 65, and the end face of the inner ring 65 is in contact with the end face of the positioning sleeve 64. At this time, the positioning plug 66 is inserted into the corresponding positioning slot 651, and then the locking nut 67 is rotated onto the threaded rod 62 to install and fix the cutting disc 3 with the two ends of the positioning sleeve 64 in a position fit, and then the square plug 68 at the end of the threaded rod 62 is aligned with the square slot 452 opened at the end of the transmission shaft 45, and then the handle 56 is twisted to make the symmetrical The transmission shafts 45 are close to each other, and then the square plug block 68 will be inserted into the square slot 452, so that the symmetrical transmission shaft 45 can be connected with the threaded rod 62 and the connecting rod 61 to form a whole, so as to facilitate the driving of the adjusted two cutting discs 3 to rotate synchronously to cut and groove the wall; therefore, by changing the length of the positioning sleeve 64 sleeved on the connecting rod 61, it is possible to adjust the distance between the two cutting discs 3, so that the construction personnel can cut two complete and parallel slots on the wall, and can also adjust the width between the two parallel slots as needed, so as to facilitate the construction of slots of different widths on the wall, and the connecting rod 61 drives the positioning sleeve 64 to rotate coaxially through the cooperation of the limiting strip 63 and the limiting long slot 641, and the positioning sleeve 64 drives the two fitted cutting discs 3 to rotate synchronously and coaxially through the cooperation of the positioning plug blocks 66 and the positioning slots 651 at the two end parts, so as to improve the stability and safety of the slotting device in constructing slots on the wall.

[0037] As an embodiment of the present invention, the adjustment support mechanism 5 further includes a sliding block 57 and a threaded sleeve 58.

[0038] In the scheme designed by the present invention, when the square plug block 68 is inserted into the square slot 452, the end face of the threaded rod 62 is flush with the end face of the transmission shaft 45, and then the threaded sleeve 58 is rotated to be threadedly connected to the flush threaded rod 62. Since the threaded sleeve 58 is slidably and rotatably connected to the transmission shaft 45 through the cooperation of the bearing and the sliding plug block 57, the threaded sleeve 58 will not interfere with the transmission shaft 45 when being threadedly connected to the threaded rod 62. After the threaded rod 62 is connected to the axis of the transmission shaft 45 through the cooperation of the square plug block 68 and the square slot 452, it will be connected to the threaded rod 62 through the threaded sleeve 58, thereby preventing the transmission shaft 45 and the threaded rod 62 from being disconnected when the cutting disc 3 is cutting grooves on the wall, thereby affecting the normal grooving construction of the cutting disc 3 on the wall.

[0039] As an embodiment of the present invention, a material guide interception mechanism 8 is provided in the collection box 7, and the material guide interception mechanism 8 includes an inclined guide plate 81, a bending guide plate 82, a rotating shaft rod 83, an electric telescopic rod 84, an elastic screen 85 and an air guide tube 86.

The bottom end of the inclined guide plate 81 is integrally formed with a bending guide plate 82, and the bending guide plate 82 is located in the collection box 7. The connection between the inclined guide plate 81 and the bending guide plate 82 is connected by a rotating shaft. The rod 83 is rotatably mounted to the box opening of the collection box 7, a semicircular elastic screen 85 is fixed on the inner wall of the collection box 7, the dust box 71 is connected to the collection box 7 through an air guide tube 86, and the pipe opening of the air guide tube 86 is located at the semicircular elastic screen 85, the bending guide plate 82 is obliquely extended to the lower side of the arc surface of the elastic screen 85, at least two electric telescopic rods 84 are vertically fixed to the lower wall of the cutting chamber 11, and the piston rods of at least two electric telescopic rods 84 are upwardly connected to the lower surface of the highest inclined end of the inclined guide plate 81;

[0040] In the scheme designed by the present invention, when the two symmetrical cutting discs 3 are grooving the wall, the dust generated by the cutting of the cutting discs 3 will be sucked into the collection box 7 through the dust suction fan and the air duct 86, and the large particles of dust will fall onto the inclined inclined guide plate 81, and then fall into the collection box 7 along the inclined guide plate 81, and the elastic screen 85 installed on the box wall of the collection box 7 will intercept and separate the incoming dust, and as the inclined guide plate 81 falls and accumulates too much dust, the piston rod of the electric telescopic rod 84 can be controlled to retract and extend, so that the inclined guide plate 81 can swing back and forth in the cutting chamber 11, so that the accumulated dust can quickly fall into the collection box 7, and when the inclined guide plate 81 swings up and down, it will drive the bending guide plate 82 to swing back and forth in the collection box 7 through the rotating shaft rod 83, so that the dust entering the collection box The dust in the collecting box 7 can quickly fall to the bottom of the box. At the same time, the swing of the bending guide plate 82 will vibrate the elastic screen 85, so that the dust gathered on the surface of the elastic screen 85 will fall off into the collecting box 7, preventing the filtered and intercepted dust from adhering to the elastic screen 85, causing the elastic screen 85 to be blocked, thereby affecting the collection and cleaning of the dust generated by the cutting. At the same time, since the bending guide plate 82 is inclined and extends downward to the outer side of the elastic screen 85, the dust entering the collecting box 7 can be blocked and guided, so that the flowing airflow first drives the dust to fall to the bottom of the collecting box 7, and then is filtered, intercepted and discharged through the elastic screen 85, which can effectively reduce the large-scale adhesion of the dust entering the collecting box 7 to the elastic screen 85, and the dust collected inside the collecting box 7 can be removed and cleaned through the bottom cover detachably installed at the bottom of the collecting box 7.

[0042] In the scheme designed by the present invention, after the cutting forms a complete slotted seam and the construction personnel clean the wall between the two parallel seams with an impact drill, the construction personnel can sleeve the brush roller 9 on the connecting rod 61 as needed, and then fix the brush roller 9 with the locking nut 67, and then install the adjustment installation assembly 6 with the brush roller 9 installed into the cutting cavity 11. The construction personnel then hold the handle 2, insert the brush roller 9 into the slotted cable trough, and then slowly move the shell 1, so that the rotating brush roller 9 will clean the slotted cable trough to prevent concrete blocks or impurities from remaining in the cable trough, thereby affecting the safe and quick installation of the wire pipe and the wire box.
