DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 , an embodiment provided by the utility model:

[0025] The knife roller body 1 and the mounting groove 11 used in the present application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0026] A chipper drum assembly that is easy to install, comprising: a knife drum body 1, a mounting groove 11 is provided on the surface of the knife drum body 1, and a thread groove 12 is provided on the inner wall of the mounting groove 11;

[0027] A tool structure 2 is installed inside the installation groove 11. The tool structure 2 includes a tool holder 21. The tool holder 21 is installed inside the installation groove 11. A tool groove 22 is provided on the surface of the tool holder 21. A blade body 23 is inserted inside the blade groove 22. A through groove 24 is provided on the surface of the blade body 23.

[0028] A fixing structure 3 is installed on the tool structure 2, and the fixing structure 3 includes a coarse stud 31, which is movably installed in the thread groove 12 through a thread, and a thin stud 32 is integrally formed on the top surface of the coarse stud 31, and a rectangular column 33 is integrally formed on the top surface of the thin stud 32. A screw sleeve 34 is installed on the upper side of the thin stud 32, and a rectangular groove 35 is provided on the bottom surface of the screw sleeve 34. A bolt 36 is movably installed on the top surface of the screw sleeve 34 through a thread, and the blade body 23 is installed in the tool holder 21. When disassembling and assembling the blade body 23, there is no need to loosen the tool holder 21. The operation is convenient, the structure is simple, and it is more practical.

[0029] Furthermore, the end of the blade body 23 is exposed from the inner side of the blade groove 22 , and the material can be chipped through the blade body 23 .

[0030] Furthermore, the left end width of the through slot 24 is greater than the right end width. When the screw sleeve 34 is inserted into the through slot 24, the blade body 23 cannot be detached from the tool holder 21. When the thin stud 32 is inserted into the through slot 24, the blade body 23 can be removed from the tool holder 21 for easy replacement.

[0031] Furthermore, the diameter of the screw sleeve 34 is greater than the diameter of the thin stud 32. When the screw sleeve 34 rises, it can drive the thin stud 32 to be located in the through groove 24, making it easy to remove and replace the blade body 23.

[0032] Furthermore, the diameter of the thin stud 32 is equal to the width of the right end of the through slot 24. When the thin stud 32 is located in the through slot 24, it cannot fix the blade body 23, and the blade body 23 can be taken out and replaced.

[0033] Furthermore, the rectangular column 33 is inserted into the rectangular groove 35, and the bolt 36 is used to fix the rectangular column 33 inside the rectangular groove 35. The rectangular column 33 cooperates with the rectangular groove 35 so that the rotation of the screw sleeve 34 can drive the thick stud 31 to rotate, which is convenient for separating the thin stud 32 downward from the through groove 24.

[0034] Working principle: During installation, insert the blade body 23 into the blade groove 22, and the blade body 23 can be installed in the tool holder 21, and then the tool holder 21 is installed downward in the installation groove 11, and the thin stud 32 passes through the blade body 23 through the through groove 24, and the screw sleeve 34 is installed on the top of the thin stud 32, and the rectangular column 33 is inserted into the rectangular groove 35, and the bolt 36 is rotated to fix the rectangular column 33 and the screw sleeve 34. Then, the screw sleeve 34 is rotated to drive the thin stud 32 and the thick stud 31 to move downward, and the thick stud 31 is lowered in the thread groove 12, and the thin stud 32 is downward away from the through groove 24, and the lower end of the screw sleeve 34 is inserted into the through groove 24, and the tool holder 21 and the blade body 23 can be fixed on the knife roller body 1;

[0035] When the blade body 23 needs to be replaced, the screw sleeve 34 is rotated in the opposite direction. The screw sleeve 34 drives the thin stud 32 and the thick stud 31 to move upward through the rectangular groove 35 and the rectangular column 33. The lower end of the screw sleeve 34 is pulled out from the through groove 24, and the thin stud 32 is located in the through groove 24, which can release the limit on the blade body 23. At this time, the blade body 23 is pulled to slide the thin stud 32 out of the through groove 24, and the blade body 23 can be removed, and a new blade body 23 is inserted into the knife groove 22, and the through groove 24 is sleeved on the outside of the thin stud 32. The screw sleeve 34 is rotated, and the lower end of the screw sleeve 34 is reinserted into the through groove 24, so that the blade body 23 can be fixed. The operation is convenient and more practical.

[0036] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model.
