[0023] Example: like Figures 1-6As shown, an adjustable cutter head device includes a cutter head 1, a cutter head shaft 2, a rotating shaft 4, an adjusting sleeve 5, and at least one blade assembly 3. The cutter head 1 is fixedly connected to the cutter head shaft 2, the blade assembly 3 is fixedly connected to the rotating shaft 4, the cutter head shaft 2 is movably connected to the rotating shaft 4, and the adjusting sleeve 5 is linked with the cutter head shaft 2 and the rotating shaft 4. By rotating the adjusting sleeve 5, the cutter head shaft 2 moves axially relative to the rotating shaft 4.

[0024] The cutter head 1 has a conventional disc structure. The cutter head 1 is provided with a cutter head hole 11 and a blade cavity 12. The cutter head hole 11 and the blade cavity 12 are connected. The cutter head shaft 2 is installed in the cutter head hole 11. The two are fastened together by screws, bolts, etc. The blade assembly 3 is located in the blade cavity 12.

[0025] In this embodiment, there is one blade assembly 3 and one blade cavity 12 for the blade disc 1. In other embodiments, there may be two or more blade assemblies 3. This application does not limit the number of blade assemblies 3, and the specific number can be set as needed.

[0026] The blade assembly 3 includes a blade holder 31 and a blade 32. The blade 32 is fixedly mounted on the blade holder 31, and the blade holder 31 is fixedly mounted on the rotating shaft 4. The blade disc shaft 2 is sleeved outside the rotating shaft 4, and the two are coaxially arranged.

[0027] The blade holder 31 includes a first mounting part 311 and a second mounting part 312. The first mounting part 311 is fastened to the rotating shaft 4 by screws, bolts, etc. The second mounting part 312 is provided with a groove 3121. The shape of the groove 3121 is adapted to the blade 32. The blade 32 is located in the groove 3121 and is fastened to it by screws, bolts, etc.

[0028] The cutter head shaft 2 and the rotating shaft 4 are connected by a positioning key 6, which restricts their circumferential rotation and allows them to move only axially. Specifically, the cutter head shaft 2 has a first positioning groove 23 and the rotating shaft 4 has a second positioning groove 40. The first positioning groove 23 and the second positioning groove 40 are distributed axially and their openings face each other, forming a positioning groove. The positioning key 6 is inserted into the positioning groove, thereby restricting the rotation between the cutter head shaft 2 and the rotating shaft 4, allowing the cutter head shaft 2 to move axially relative to the rotating shaft 4.

[0029] The linkage between the adjusting sleeve 5, the cutter head shaft 2, and the rotating shaft 4 is as follows: The cutter head shaft 2 is provided with at least one track groove 20, which is axially upward. The adjusting sleeve 5 is fixed with at least one positioning screw 51, which corresponds one-to-one with the track groove 20. The positioning screw 51 passes through the track groove 20 and is slidably connected to the track groove 20. When the adjusting sleeve 5 is rotated, the positioning screw 51 slides along the track groove 20. According to the track groove 20, the positioning screw 51 presses down or lifts the cutter head shaft 2 so that it moves axially upward or downward relative to the rotating shaft 4.

[0030] To lock the cutter head shaft 2 in the required position and thus fix the distance between the cutter head 1 and the blade 32, this application also includes a locking structure. The locking structure includes a spring plunger 71, which is mounted on the rotating shaft 4. The adjusting sleeve 5 is provided with spring plunger holes 51. When the adjusting sleeve 5 rotates, the spring plunger 71 moves through several spring plunger holes 51. When the adjusting sleeve 5 stops rotating, the ball head of the spring plunger 71 pops out and locks into the spring plunger hole 51 to achieve locking.

[0031] The spring plunger 71 is an existing structure that has been procured, and this application does not modify or apply it.

[0032] Preferably, a plurality of spring plunger holes 51 are arranged in a ring shape on the adjusting sleeve 5.

[0033] Preferably, the rotating shaft 4 is provided with a limiting groove 41, which is an annular groove distributed around the shaft. The limiting groove 41 is opposite to the positioning screw 51. The positioning screw 51 is inserted into the trajectory groove 20 and the limiting groove 41 from the outside to the inside. When the adjusting sleeve 5 drives the positioning screw 51 to rotate, the front end of the positioning screw 51 is supported by the limiting groove 41 and slides along the limiting groove 41. The limiting groove 41 plays a supporting role for the positioning screw 51, ensuring the stability of the positioning screw 51.

[0034] Preferably, the outer surface of the adjusting sleeve 5 is textured to enhance friction.

[0035] The cutter head shaft 2 includes a shaft end 21 and a shaft post 22. The shaft end 21 is fixedly connected to the shaft post 22 and the shaft end 21 is fixedly connected to the cutter head 1. The track groove 20 is fixedly installed on the shaft post 22 and is wound around the shaft post 22.

[0036] The shaft end 21 is provided with a clearance position 211, and the blade holder 31 is set in the clearance position 211. The clearance position 211 serves to position and limit the installation of the blade holder 31.

[0037] The rotating shaft 4 includes a rotating column 42 and a rotating end 43. The rotating column 42 and the rotating end 43 are fixedly connected. The first mounting part 311 of the blade holder 31 is fastened to the rotating column 42 by screws, bolts, etc. The second positioning groove 40 and the limiting groove 41 are provided on the rotating column 42. The spring plunger 71 is installed on the rotating end 43.

[0038] Preferably, the rotating shaft 4 is provided with an annular cavity 44, and a washer 8 is provided in the annular cavity 44. The washer 8 contacts the adjusting sleeve 5, which can reduce the resistance when the adjusting sleeve 5 rotates.

[0039] The implementation process of the example is as follows: Initially, the blade assembly 3 and the cutter head 1 maintain the maximum distance. At this time, the positioning screw 51 is located at the highest position of the track groove 20. When adjustment is required, the adjusting sleeve 5 is rotated, and the positioning screw 51 moves downward along the track groove 20, controlling the cutter head shaft 2 to move downward along the axis, thereby driving the cutter head 1 to move downward, thus reducing the distance between the blade assembly 3 and the cutter head 1. When the required distance is reached, the adjusting sleeve 5 stops rotating, and the spring plunger 71 is engaged with the spring plunger hole 51 to achieve locking. When the distance needs to be increased, the adjusting sleeve 5 is rotated in the opposite direction.

[0040] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort should fall within the protection scope of this utility model.
