DETAILED DESCRIPTION

[0025] This embodiment discloses a cutting device for road maintenance, comprising a base 1, a motor vibration reduction box 2 installed on the base 1, and a protective cover 3 installed on the side wall of the motor vibration reduction box 2;

[0026] A motor 5 is installed in the motor damping box 2 through a damping mechanism, a cutting blade 51 is detachably installed on the power output shaft of the motor 5, and the protective cover 3 is provided on the outer cover of the cutting blade 51; a reserved groove is provided on the side wall of the motor damping box 2 to facilitate the power output shaft of the motor 5 to extend into the protective cover 3;

[0027] like Figure 2 and Figure 3 As shown, the protective cover 3 is a fan-shaped structure, and a fan ring gap is reserved;

[0028] A noise-reducing sound-absorbing board 31 is installed on the inner wall of the protective cover 3; in specific implementation, the sound-absorbing board 31 is one of a foam sound-absorbing board, a polyester fiber sound-absorbing board, and a mineral wool sound-absorbing board, so as to be close to the sound source end to achieve noise reduction processing;

[0029] A plurality of dust reduction cooling nozzles 32 are also installed on the inner wall of the protective cover 3, and each dust reduction cooling nozzle 32 is supplied with water through a water injection pipe 8 and a water pump 9; wherein the plurality of dust reduction cooling nozzles 32 are connected to the water tank 10 through the water injection pipe 8, and are specifically transported through the water pump 9.

[0030] like Figure 1 As shown, the vibration reduction mechanism includes a lower vibration reduction seat 4 for elastically supporting the motor 5 and an upper pressing seat 6 for pressing the top surface of the motor 5; wherein the lower vibration reduction seat 4 is mounted on the base 1 through a plurality of lower guide rods 41 and lower vibration reduction springs 42; and the upper pressing seat 6 is mounted on the top surface of the motor vibration reduction box 2 through a plurality of upper guide rods 61 and upper vibration reduction springs 62;

[0031] Therefore, even if the cutting blade 51 vibrates and transmits sound waves to the motor 5, the lower vibration damping seat 4 and the upper clamping seat 6 can play a buffering role and prevent the cutting blade 51 from colliding violently with the hard structure.

[0032] In this embodiment, the base 1 is installed on a trolley or a traction mechanism, so as to facilitate the adjustment of the cutting depth according to needs, or the transportation and transfer of the cutting device.

[0033] In this embodiment, a plurality of linear bearings corresponding to the upper guide rod 61 are installed on the top plate of the motor damper box 2; a limit plate is installed at the uppermost end of the upper guide rod 61; and the upper guide rod is utilized to ensure the vertical lifting and lowering of the upper clamping seat.

[0034] In this embodiment, the dust reduction cooling nozzles 32 are respectively arranged on both sides of the cutting disc 51; on the one hand, the cutting disc is cooled by spraying water or atomizing the dust reduction cooling nozzles, and on the other hand, dust reduction treatment can also be carried out with the help of the dust reduction cooling nozzles.

[0035] In this embodiment, a bearing seat 7 for supporting the power output shaft of the motor 5 is installed on the lower vibration damping seat 4.

[0036] When in use, the motor 5 is started to drive the cutting disc 51 to rotate. At the same time, the water pump 9 and the water injection pipe 8 are used to inject water into each dust reduction cooling nozzle 32, so that the water is sprayed on the cutting disc 51 to cool it down, and the purpose of dust reduction can also be achieved.

[0037] During this process, the sound waves generated by the vibration between the cutting disc 51 and the surface to be cut are, on the one hand, partially absorbed by the sound absorbing plate 31 in the protective cover 3; on the other hand, the vibration transmitted to the vibration damping seat is buffered by the spring, thereby reducing the transmission of noise sound waves.

[0038] The above embodiments are only descriptions of the preferred methods of the invention, and are not intended to limit the scope of the invention. Without departing from the design spirit of the invention, various modifications and improvements made to the technical solution of the invention by ordinary technicians in this field should fall within the protection scope of the claims of the invention.
