[0002] A wood chipper is a wood processing equipment mainly used to process wood into craft wood chips. It is widely used in the raw material preparation section of industries such as papermaking, artificial board, pulping and textiles. Currently, wood chippers include a feed roller, which cuts the material through the feed roller.

[0003] The existing feed rollers have evenly distributed teeth on their surface. During use, the feed rollers use these teeth to clamp and transport materials. After a period of use, the teeth will wear and deform due to friction with the materials, which will affect the feeding efficiency of the feed rollers. Since the teeth are integrated with the roller body, they cannot be replaced individually, which increases the operating costs for enterprises.

[0004] Therefore, in order to solve the above problems, a split-type feed roller for chippers is proposed. Utility Model Content

[0012] This invention features a positioning structure. A triangular reinforcing plate is inserted into the inner side of the mounting groove, and the plate is moved left and right until its left and right ends align with the left and right ends of the roller body. At this point, the connecting groove aligns with the second threaded groove. A first bolt is then inserted into the connecting groove and rotated. The bottom end of the first bolt is screwed into the inner side of the second threaded groove, thus fixing the triangular reinforcing plate inside the mounting groove. The gear body is then inserted into the inner side of the mounting groove from one side. A limiting block and a positioning block are inserted into the limiting grooves on the surface of the gear body, providing limiting for the installation of the gear body inside the mounting groove. Furthermore, the triangular reinforcing plate abuts against the gear body, supporting the back of the gear body to enhance its rigidity and improve its material conveying efficiency. As a result, the two sets of side meshing discs are respectively attached to the left and right side walls of the roller body. The second bolt is inserted through the side meshing disc and rotated to screw the end of the second bolt into the first threaded groove, thereby fixing the side meshing disc to the side wall of the roller body. The side meshing disc is attached to the triangular reinforcing plate and the meshing tooth body, which can provide a limit for further fixing the triangular reinforcing plate and the meshing tooth body on the roller body surface, ensuring the stability of the device. When one set of meshing tooth bodies wears out, the second bolt is reversed to remove the side meshing disc from the roller body. The meshing tooth body is pushed left and right to push the worn meshing tooth body out of the mounting groove. The new meshing tooth body is then reinserted into the mounting groove, allowing for individual replacement of the worn meshing tooth body. The operation is convenient and labor-saving, reducing the maintenance cost of the device and improving the economic benefits of the enterprise. Attached Figure Description
