[0025] An adjustable blade drum for a chipper includes: a blade drum body 1, the surface of which has a groove 11 and a mounting cavity 12;

[0026] A positioning structure 2 is installed inside the mounting cavity 12. The positioning structure 2 includes a tool holder 21, which is movably installed inside the mounting cavity 12. A mounting groove 22 is formed on the surface of the tool holder 21. A guide strip 23 is integrally formed on the inner bottom surface of the mounting groove 22. A positioning bolt 24 is threadedly connected to the top surface of the tool holder 21. A blade body 25 is movably installed inside the mounting groove 22. A reserved groove 26 is formed on the surface of the blade body 25. A threaded rod 27 is threadedly connected to the inside of the right side wall of the blade body 25. A rotating rod 28 is movably installed inside the blade roller body 1 through a bearing. Through the cooperation of the threaded rod 27 and the rotating rod 28, the threaded rod 27 and the rotating rod 28 can be spliced ​​when the tool holder 21 is installed. When it is necessary to adjust the extension length of the blade body 25, rotating the rotating rod 28 will drive the threaded rod 27 to rotate. The threaded rod 27 is threadedly connected to the blade body 25, which can drive the blade body 25 to move inside the mounting groove 22, thereby realizing the convenient adjustment of the extension length of the blade body 25 and improving the practicality of the device.

[0027] Furthermore, three sets of grooves 11 and mounting cavities 12 are provided respectively, and the three sets of grooves 11 and three sets of mounting cavities 12 are staggered. The mounting cavities 12 provide a position for the installation of the positioning structure 2.

[0028] Furthermore, the guide bar 23 is slidably installed on the bottom surface of the blade body 25, and the positioning bolt 24 passes through the blade body 25 via the reserved groove 26. The bottom end of the positioning bolt 24 is threadedly connected to the inner wall of the mounting cavity 12. The guide bar 23 provides guidance for the installation of the blade body 25 inside the mounting groove 22. The blade body 25 can move outside the positioning bolt 24 through the reserved groove 26 to adjust the extension length. The tool holder 21 can be fixed inside the mounting cavity 12 by the positioning bolt 24.

[0029] Furthermore, the right side wall of the blade body 25 fits against the inner wall of the mounting groove 22, and the threaded rod 27 is movably mounted inside the tool holder 21 via a bearing. The rotation of the threaded rod 27 can drive the blade body 25 to move inside the mounting groove 22.

[0030] Furthermore, the right end of the threaded rod 27 is provided with a hexagonal groove, and the left end of the rotating rod 28 is integrally formed with a hexagonal block. The left end of the rotating rod 28 is located inside the mounting cavity 12 and is inserted into the tool holder 21. The left end of the rotating rod 28 can rotate inside the tool holder 21 to facilitate the engagement of the threaded rod 27.

[0031] Furthermore, the hexagonal block is adapted to the hexagonal slot, and the hexagonal block is inserted inside the hexagonal slot. The rotation of the rotating rod 28 can drive the threaded rod 27 to rotate through the hexagonal block and the hexagonal slot, so as to realize the convenient adjustment of the extension length of the blade body 25.

[0032] Working principle: During installation, insert the blade body 25 into the mounting groove 22, and then use a hex wrench to rotate the threaded rod 27. The threaded rod 27 is threadedly connected to the blade body 25. The rotation of the threaded rod 27 will cause the blade body 25 to move inside the mounting groove 22, and the guide bar 23 can slide on the bottom surface of the blade body 25, which can guide and limit the installation of the blade body 25 inside the mounting groove 22. Place the tool holder 21 together with the blade body 25 inside the mounting cavity 12. Since the tail end of the blade body 25 is in contact with the inner wall of the mounting groove 22, the angle of the threaded rod 27 is matched with the angle of the rotating rod 28. The hexagonal block at the left end of the rotating rod 28 will be inserted into the hexagonal slot at the right end of the threaded rod 27. Then rotate the positioning bolt 24. The positioning bolt 24 passes through the tool holder 21 and the reserved groove 26, so that the tool holder 21 can be stably installed inside the mounting cavity 12.

[0033] When it is necessary to adjust the extension length of the blade body 25 from the surface of the cutter roller body 1, use a hex wrench to rotate the rotating rod 28. The rotating rod 28 drives the threaded rod 27 to rotate through the hexagonal block and hexagonal groove. The threaded rod 27 is threadedly connected to the blade body 25. When the threaded rod 27 rotates, it drives the blade body 25 to move inside the mounting groove 22, which can realize the convenient adjustment of the extension length of the blade body 25 and improve the ease of use of the device.
