In addition, the terms "first" and "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.
[0023] As Figures 1 to 5As shown, the built-in dust removal and noise reduction structure of the blade shredder of the embodiment includes two support frames 1, which have a certain supporting effect, and a protective shell 3 is commonly installed at the upper end of the two support frames 1, which is made of metal and used for protection to avoid excessive contact between the internal mechanical structure and the outside world. A material channel 17 is formed in the inside of the protective shell 3, which is a longitudinal through groove. An inlet hopper 4 is installed outside the upper end of the material channel 17. The materials to be shredded are put into the inside of the material channel 17 through the inlet hopper 4. Two rotating blade groups 6 are rotatably connected to the inside of the material channel 17 above. The two rotating blade groups 6 are arranged in a staggered manner and are both connected with driving devices. The materials are shredded by the two rotating blade groups 6. A ring of first sound insulation cotton 7 is installed outside the rotating blade group 6 and inside the protective shell 3. The first sound insulation cotton 7 can have a certain sound insulation effect. An installation groove 5 is formed at the position of the two sides of the rotating blade group 6 of the protective shell 3. A plurality of buffer structures 8 are installed in the inside of the installation groove 5. The buffer structures 8 are used to offset and slow down the vibration generated when the rotating blade group 6 shreds the materials. A connecting spring rope 11 is commonly installed between the plurality of buffer structures 8. The connecting spring rope 11 can enhance the connection strength of the plurality of buffer structures 8, and in turn enhance the buffering effect of the buffer structures 8 on the vibration.

One clamping plate 801 is in contact with the bottom end of the installation groove 5, and the other clamping plate 801 is supported by the four side supporting arms 805. The pendulum ball 803 is installed between the two mounting columns 802 through the two elastic ropes 804. When the shredder is running, the vibration will be transmitted to the buffer structure 8. At this time, the pendulum ball 803 will produce irregular operation due to the vibration. In the process of the operation of the pendulum ball 803, the force from the vibration transmission will be consumed, thereby having a certain buffering effect. A through hole 806 is formed at the central position of the side supporting arm 805. The connecting spring rope 11 is connected with the surface of the pendulum ball 803 through the through hole 806. The position close to the pendulum ball 803 of the side supporting arm 805 is a semicircular arc groove, which can avoid the contact between the pendulum ball 803 and the side supporting arm 805 when the pendulum ball 803 swings.

[0027] Further, a triangular pyramid 2 is installed between the two support frames 1 and below the material channel 17, and the triangular pyramid 2 can guide the crushed material in different directions to avoid accumulation of the material at the bottom.
[0028] The use method of the embodiment is as follows: the material enters the material channel 17 through the feeding hopper 4, the two rotary blade sets 6 are started to crush the material, the crushed material is discharged through the lower end opening of the material channel 17, the two mounting grooves 5 are provided inside the protection shell 3, a plurality of buffer structures 8 are installed inside the mounting grooves 5, the plurality of buffer structures 8 are connected by the connecting spring ropes 11, the vibration generated during the operation of the rotary blade sets 6 is transmitted to the inside of the plurality of buffer structures 8, the vibration is buffered by the buffer structures 8, the connecting spring ropes 11 can enhance the connection strength of the plurality of buffer structures 8, thereby enhancing the buffering effect of the buffer structures 8 on the vibration, the first sound insulation cotton 7 is installed outside the rotary blade sets 6, and the second sound insulation cotton 9 is installed on the side wall surface of the mounting groove 5, which can block the noise generated by the shredder to a certain extent, thereby avoiding the interference of the noise on the operator.
