Description

Technical Field

[0001] This utility model relates to the field of wood chipper technology, specifically to a large-diameter wood disc chipper with adjustable cutting angle. Background Technology

[0002] A wood chipper is a specialized piece of equipment for producing wood chips. It is also called a wood slicer and belongs to the wood processing equipment series.

[0003] Application number CN202410862049.1 discloses a large-diameter log disc chipper with adjustable cutting angle. The chipping system is automatically rotated by an angle-adjusting motor, ensuring adjustable angle between the chipper and the feed direction during chipping. This allows for the chipping of logs with suitable angles and shapes. Adjusting the cutting angle adjusts the cutting force, ensuring reasonable cutting force for logs of different diameters. Furthermore, the movable frame is more stable with the support of an auxiliary arc-shaped slide rail, meeting the design reliability requirements. However, this design has shortcomings. The chipper's height is not adjustable, limiting its use. When not in use, it lacks a protective mechanism, making it susceptible to accidental contact. Additionally, the directly exposed cutting components pose a safety hazard.

[0004] Therefore, we propose a large-diameter wood disc chipper with adjustable cutting angle. Utility Model Content

[0005] The main purpose of this utility model is to provide a large-diameter wood disc chipper with adjustable cutting angle. Through the design of the installation mechanism, the height of the chipper body can be easily adjusted, allowing the chipper body to be used flexibly. The protective cover is placed on the upper part of the outer side of the chipper body, which can protect the chipper body when it is not in use, avoid damage caused by accidental collision, and improve its safety. This can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A large-diameter wood disc chipper with adjustable cutting angle includes a chipper body, a mounting mechanism, and a protective cover. The chipper body is mounted on the mounting mechanism, and a protective cover is fitted over the upper outer part of the chipper body. The protective cover is located above the mounting mechanism, and a top plate is fixedly connected to the top of the protective cover. The mounting mechanism includes a support plate, a first limiting plate, a second limiting plate, a piston rod, a base, a limiting component, and an electric cylinder. The support plate is a horizontally arranged rectangular plate structure, and the bottom end of the chipper body is connected to the upper surface of the support plate.

[0008] A box is vertically connected to one end of the upper surface of the support plate, and a column is fixedly connected to the top of the box. The column has a groove for installing a threaded rod. The top plate is located in the groove and is fitted onto the threaded rod. The end of the top plate away from the protective cover is fixedly connected to the end of the limiting block.

[0009] By adopting the above technical solution

[0010] Specifically, the base is located directly below the support plate, and multiple relatively parallel electric cylinders are fixedly installed on the inner wall of the bottom end of the base, with piston rods connected to the top of the electric cylinders.

[0011] Specifically, the top of the piston rod passes through the base and is vertically inserted into the lower end face of the support plate, and a rectangular frame structure limiting member is fixedly sleeved on the lower outer side of the base.

[0012] Specifically, the housing has a mounting cavity for installing the motor located directly below the slide groove.

[0013] Specifically, the top end of the threaded rod is rotatably connected to the inner wall of the top of the slide groove, and the bottom end of the threaded rod passes through the top of the housing and is connected to the output shaft at the top of the motor.

[0014] Specifically, a stop bar for limiting the position of the top rod is fixedly engaged at the center of the column near the chipper body, and observation ports are provided on both sides of the protective cover.

[0015] The beneficial effects of this utility model are:

[0016] (1) The large-diameter wood disc chipper with adjustable cutting angle described in this utility model, through the design of the first limiting plate, the second limiting plate and bolts, enables the chipper body to be fixedly assembled on the mounting mechanism. Through the design of the mounting mechanism, it is convenient to adjust the height of the chipper body. Multiple sets of electric cylinders move upward synchronously, and the piston rod can push the support plate upward until the chipper body is pushed to the specified height, thereby achieving the purpose of adjusting the height of the chipper body;

[0017] (2) The large-diameter wood disc chipper with adjustable cutting angle described in this utility model has a protective cover placed on the upper part of the outer side of the chipper body. When the chipper body is not in use, it can protect it and prevent damage caused by accidental contact, while also improving its safety. When the chipper body needs to be used, the motor drives the threaded rod to rotate. Through the threaded engagement between the threaded rod and the top plate, the protective cover can move upward until the chipper body is fully exposed. It has the advantage of simple operation.

[0032] In use, the chipper body 1 is assembled onto the mounting mechanism 2. The chipper body 1 is placed on the upper surface of the support plate 3 and is located between the first limiting plate 16 and the second limiting plate 17. The first limiting plate 16 and the second limiting plate 17 are fixedly connected to the bottom of the chipper body 1 by bolts. A box 7 and a column 8 for installing the protective cover 9 are provided on one side of the chipper body 1. The protective cover 9 is fitted on the upper outer side of the chipper body 1. When the chipper body 1 needs to be used, the motor 14 drives the threaded rod 13 to rotate. Through the threaded engagement between the threaded rod 13 and the top plate 11, the protective cover 9 can move upward until the chipper body 1 is fully exposed.
