[0040] A discharge barrel 4 is provided on the right side of the mounting base 1, one end of which is connected to a dust collecting sleeve 5, and the other end is connected to a dust collecting bag 6; the dust collecting sleeve 5 is in contact with the inner wall of the mounting base 1 and the dust collecting port of the dust collecting sleeve 5 is close to the tangent direction of the blade of the cutting disc 2.

[0041] A pair of rotating wheels 7 are rotatably arranged on the left and right sides of the bottom of the mounting base 1 . The rotating direction of the rotating wheels 7 is the same as that of the cutting blade 2 . The bottom end of the rotating wheel 7 is higher than the bottom end of the disc-shaped cutting blade 2 and lower than the bottom end of the mounting base 1 .

[0042] The electrical secondary piping line grooving device of the utility model is provided with a dust collecting sleeve 5, a discharge barrel 4 and a dust collecting bag 6, which can collect dust in time when the cutting blade 2 generates dust during cutting, reduce the dust debris from being scattered into the air, avoid inhalation by operators, and protect the health of operators.

[0043] When in use, the operator controls the device to realize mobile cutting of the electrical secondary piping line grooving device by rotating the wheel 7, thereby improving work efficiency and being suitable for large-scale use and promotion in industry.

[0044] As a preferred solution, both ends of the rotating wheel 7 are coaxially connected with a rotating shaft 8; the rotating shaft 8 is rotatably connected to the corresponding side wall of the mounting base 1;

[0045] The two rotating wheels 7 are connected via two transmission belts 9 , and the two transmission belts 9 are respectively mounted on two rotating shafts 8 located on the same side.

[0046] Through the cooperation between the rotating belt 9 and the rotating wheel 7, the bottom end of the rotating belt 9 is pressed against the wall, thereby forming a closed space at the bottom of the mounting base 1, further ensuring that debris and dust generated during operation do not enter the external space.

[0047] Specifically, Figure 3 As shown, the upper end of the mounting base 1 is closed by a fixing shell 10, and the fixing shell 10 is sealed and plugged into the interior of the mounting base 1;

[0048] A rotating shaft is arranged in the middle of the cutting blade 2, and the rotating shaft is rotatably connected to the fixed shell 10. The output shaft of the rotating motor 3 drives the rotating shaft to rotate through a belt transmission, thereby driving the cutting blade 2 to rotate.

[0049] As a preferred solution, a compression spring 11 is provided between the fixing shell 10 and the mounting base 1;

[0050] When the compression spring 11 is not compressed, the cutting blade 2 is located inside the mounting base 1 ; after the compression spring 11 is compressed, the bottom end of the cutting blade 2 is lower than the bottom end of the rotating wheel 7 .

[0051] Further preferably, first limit plates 12 are disposed on both left and right sides of the fixed shell 10 ; and second limit plates 13 corresponding to the two first limit plates 12 are disposed inside the mounting base 1 .

[0052] Limiting rods 14 are disposed at the front and rear positions of the second limiting plates 13 ; the limiting rods 14 slide through the corresponding first limiting plates 12 .

[0053] A compression spring 11 is sleeved on each limiting rod 14 , and the compression spring 11 is located between the first limiting plate 12 and the second limiting plate 13 .

[0054] This arrangement enables the cutting blade 2 to be stored inside the mounting base 1 when not in use. When in use, the cutting blade 2 can be extended to work by pressing the fixing shell 10, thereby ensuring safety.

[0055] Further preferably, the first limiting plate 12 and the second limiting plate 13 located on the right side of the fixing shell 10 and the mounting base 1 do not contact the dust collecting sleeve 5 .

[0056] Further preferably, a handle 15 is provided at the top of the fixed shell 10 to facilitate an operator to move the device.

[0057] As a preferred solution, a movable plate 16 is connected to the lower part of one side of the mounting base 1; a movable wheel 17 is rotatably arranged at the bottom of the movable plate 16; the bottom end of the movable wheel 17 is located in the same plane as the bottom end of the rotating wheel 7;

[0062] The rolling wheel 61 contacts the wall under the push of the torsion spring 1902, and the rolling wheel 61 rotates along with the movement of the base 1. The rotating motor 3 drives the cutting blade 2 to rotate through the belt transmission, and presses the fixed shell 10, thereby driving the high-speed rotating cutting blade 2 to contact and cut the wall. The generated debris and dust will be thrown out from the tangential direction of the cutting blade 2 and guided to the dust collecting bag 6.

[0063] The base 1 is pushed to move and cut out the wire groove. At the same time, under the push of the torsion spring 1902, the guide plate 1903 extends into the wire groove to play a certain blocking role. The guide wheel 1904 contacts the bottom of the wire groove, further reducing the discharge of debris and dust from the wire groove, thereby reducing dust in the air and preventing workers from inhaling it and affecting their health.
