[0021] The present invention is described below with specific embodiments, but is not intended to be a limitation of the present invention.

[0022] Embodiment 1

[0023] like Figure 1-Figure 3As shown, in this embodiment, the rotary cutting pulverizer provided includes multiple groups of pulverizer groups, and the pulverizer groups include teeth 1 and branch pipes 10 that can rotate relative to each other. The teeth 1 and branch pipes 10 can crush the material into protruding parts with sharp edges during the rotation process, and their main function is to grab and shear the material. When the teeth 1 rotate, they will produce friction and impact with the material, thereby crushing the material. In the crushing process, the relative rotation of the teeth 1 and branch pipes 10 is the key. This rotation can generate shear force, impact force and friction force, which work together to crush the material.

[0024] The biting teeth 1 are provided with a plurality of embedded openings, and the design of the embedded openings helps the material to be better captured and crushed during the rotation of the biting teeth 1. When the material is caught by the biting teeth 1 and brought into the embedded openings, due to the special shape and structure of the embedded openings, the material will be subjected to a more concentrated crushing force, thereby achieving more efficient crushing. A ventilation hole is provided at the root of the embedded opening. When the embedded opening is close to one side of the branch pipe 10, the ventilation hole can form an inward suction force on the embedded opening. When the embedded opening is far away from one side of the branch pipe 10, the ventilation hole can form an outward blowing force on the embedded opening. The setting of the ventilation hole further enhances the crushing effect of the biting teeth 1. When the embedded opening is close to one side of the branch pipe 10, the ventilation hole helps the material to fit more closely on the biting teeth 1 by generating an inward suction force, thereby preventing the material from escaping during the crushing process. This suction force also helps to push the material further into the embedded opening, thereby increasing the depth and effect of the crushing.

[0025] When the inner opening is away from the side of the branch pipe 10, the ventilation hole generates an outward blowing force. This blowing force helps to blow the crushed material out of the inner opening, so that it continues to enter the next round of crushing process or is discharged from the crushing knife group. In this way, the biting teeth 1 can continuously and efficiently process the material and avoid the accumulation or blockage of the material in the inner opening.

[0026] The embedded opening includes a tip notch embedded in the inside of the biting tooth 1, the tip notch points to the inside of the biting tooth 1, and the ventilation hole is connected to the end of the tip. The connection between the ventilation hole and the end of the tip notch means that the airflow can directly act on the material contacted by the tip. When the embedded opening is close to one side of the branch pipe 10, the suction force generated by the ventilation hole will be concentrated on the tip, further helping the material to enter the embedded opening. When the embedded opening is far away from one side of the branch pipe 10, the blowing force generated by the ventilation hole will also act on the material through the tip, pushing it out of the embedded opening to prevent blockage.

[0027] Embodiment 2

[0028] like Figure 2As shown, based on the first embodiment, this embodiment provides a rotation method for the biting tooth 1 and the branch pipe 10. A ring sleeve 2 is fixed inside the biting tooth 1 and the branch pipe 10. A mounting hole is provided inside the ring sleeve 2. The ventilation hole inside the biting tooth 1 passes through the ring sleeve 2 and is connected to the mounting hole inside the ring sleeve 2. The provision of the ring sleeve 2 enhances the structural stability of the biting tooth 1 and the branch pipe 10. The ring sleeve 2 serves as a fixing part to tightly connect the biting tooth 1 and the internal part of the branch pipe 10, reducing the possibility of loosening or damage caused by rotation or vibration. A filter screen 9 is provided inside the ventilation hole to filter impurities. The inner ring surface of the ring sleeve 2 fits with the outer ring surface of the inner tube 3 to ensure that the ring sleeve 2 can rotate freely.

[0029] Embodiment 3

[0030] like Figure 1-Figure 5 As shown, this embodiment provides a pulverizing assembly, including the rotary cutting pulverizing blade in the above-mentioned embodiment 2, the pulverizing assembly includes two inner tubes 3, the biting teeth 1 and the branch pipe 10 are rotatably mounted on the two inner tubes 3 respectively, the inner tube 3 is provided with an air outlet cavity 6 and an air extraction cavity 7, when the end of the vent hole is connected to the air outlet cavity 6, the gas inside the air outlet cavity 6 can be discharged from the vent hole to the outside, when the end of the vent hole is connected to the air extraction cavity 7, the air extraction cavity 7 can be exhausted inward through the vent hole, and the inner tube 3 is provided with an air outlet cavity 6 and an air extraction cavity 7. The arrangement of these two cavities is connected to the vent hole on the biting teeth 1, and by controlling which cavity the vent hole is connected to, the directional flow of the air flow can be achieved. When the end of the vent hole is connected to the air outlet cavity 6, the gas inside the air outlet cavity 6 can be discharged from the vent hole to the outside, forming an outward blowing force, which helps to blow the crushed material out of the embedded opening to avoid blockage. When the end of the ventilation hole is connected to the air extraction chamber 7, the air extraction chamber 7 can extract air inward through the ventilation hole to form an inward suction force, which helps to fit the material more closely to the biting teeth 1 and enhance the crushing effect. A baffle 8 is provided inside the inner tube 3, and the air outlet chamber 6 and the air extraction chamber 7 are respectively arranged on both sides of the baffle 8. An air outlet pipe 4 and an air extraction pipe 5 are installed on the inner tube 3. The air outlet pipe 4 is connected to the air outlet chamber 6, and the air extraction pipe 5 is connected to the air extraction chamber 7 to provide power for the air outlet chamber 6 and the air extraction chamber 7. The air outlet pipe 4 and the air extraction pipe 5 are respectively connected to the fan and the air extraction pump outside the crushing assembly.

[0031] Working principle: When the crushing assembly is started, the branch pipe 10 and the biting teeth 1 begin to rotate relative to each other, and the gap between them becomes the main working area for material crushing. After the material is brought into this area, it is sheared, impacted and rubbed between the biting teeth 1 and the branch pipe 10, and is gradually broken into smaller particles.

[0032] During the crushing process, a key mechanism plays an important role. A ventilation system is designed inside the tooth 1. When the tooth 1 rotates to form a certain angle with the branch pipe 10, the ventilation holes inside the tooth 1 are connected to a specific cavity, which is called the suction cavity. At this time, the suction cavity generates suction, which acts on the embedded opening of the tooth 1 through the ventilation holes. This suction helps to adsorb the material more tightly between the tooth 1 and the branch pipe 10, ensuring that the material will not fall off or escape during the crushing process.

[0033] When the material is fully broken, the bite teeth 1 continue to rotate, so that the ventilation holes inside it are connected to another cavity, which is referred to as the blowing chamber. At this time, the blowing chamber generates a blowing force through the ventilation holes, which acts on the inner opening. This blowing force effectively blows out the material remaining in the inner opening, causing it to leave the area between the bite teeth 1 and the branch pipe 10, thereby completing the material discharge process.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
