In the assembling process of the cutter head mechanism of the application, only the blade 1 is placed into the containing groove 3, and then the first cover body 201 and the second cover body 202 are connected and fixed by being matched with each other, so that the overall assembling process of the cutter head mechanism is simple and convenient; the blade 1 is installed and fixed by using the containing groove 3, so that the contact area between the blade 1 and the cutter holder 2 is more, the connection state of the blade 1 installed on the cutter holder 2 is more stable, the stress on the blade 1 is more uniform, and the deformation of the blade 1 in the using process is also reduced.
[0039] Preferably, the number of the blade 1 is four and is uniformly distributed on the circumference of the cutter holder 2; so that the scraping actions of the blades 1 are orderly performed.
[0040] Referring to Figure 3 , 4 , 5, 6, 7, the first cover body 201 and the second cover body 202 are both provided with the containing groove 3, the containing groove 3 is provided with a clamping groove 4 which is communicated therein, the blade 1 is provided with a protruding part 103 on the side edge, and the protruding part 103 and the clamping groove 4 are matched and clamped with each other. The structure of the protruding part 103 and the clamping groove 4 is simple, and the connection and installation of the protruding part 103 and the clamping groove 4 is very stable.
[0041] The protruding part 103 is symmetrically arranged on both sides of the inner end part 102, and the clamping groove 4 is communicated and arranged on one end of the containing groove 3 which is close to the rotating axis of the cutter holder 2. The symmetric arrangement of the protruding part 103 makes the stress on both sides of the blade 1 more uniform, avoids the deformation of the blade 1 due to uneven stress, and affects the use, and the protruding part 103 is located on the side edge of the inner end part 102, so that the moment which can be generated by the protruding part 103 relative to the overall length of the blade 1 is larger, and the ability of the blade 1 to withstand the torsion in the using process is stronger.
[0042] Referring to Figure 3 , 4, 5, 6, 7, the knife holder 2 is provided with a plurality of convex portions 203 in the circumferential direction, the blade 1 is connected to the outermost end of the convex portion 203, the outer side of the convex portion 203 includes a facing surface 204 and a back surface 205 which are separately arranged on both sides of the blade 1, all the facing surfaces 204 are inclined to the clockwise direction or the counterclockwise direction relative to the blade 1, and the facing surface 204 is arc-shaped with the middle part protruding outward.
