Abstract
Description
Technical Field
[0001] This utility model relates to the field of chipper technology, specifically a flying knife for a chipper that is easy to install. Background Technology
[0002] A chipper is a machine specifically designed to cut wood, hay, or other materials into thin slices. It is widely used in industries such as wood processing, feed processing, and waste disposal. It uses high-speed rotating blades to chip materials into uniform thin slices for subsequent processing or direct use. In a chipper, the flying knife is a special type of cutting tool designed for high-speed rotation to cut and thin materials efficiently. It has high sharpness and wear resistance, thus significantly improving production efficiency and cutting quality.
[0003] However, the flying blades of existing chippers will wear out during use, requiring timely replacement. However, the installation and replacement process is relatively laborious. During installation, the flying blades must be accurately positioned first and then fixed, which is cumbersome. Furthermore, if the positioning is inaccurate, the flying blades may become unstable, thus affecting the chipper's working efficiency and cutting quality.
[0004] Therefore, this utility model provides a flying knife for a chipper that is easy to install, in order to solve the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] This utility model provides a throwing knife, such as Figures 1-4 As shown, a chipper blade that is easy to install includes a handle 1. A first insertion block 2 is fixedly connected to one side of the handle 1. A slot is formed on the front surface of the first insertion block 2, and a connecting component is inserted into the slot.
[0025] The connecting assembly includes a rod 3, one end of which is inserted into the inside of a slot, and the other end of which is fixedly connected to a second insertion block 15. A first spring 4 is fixedly connected to the front surface of the second insertion block 15, and a force plate 14 is fixedly connected to one side of the first spring 4. A drive frame 5 is fixedly connected to both the upper and lower surfaces of the second insertion block 15. Pulling the drive frame 5 can compress the first spring 4 through the second insertion block 15, and then the first insertion block 2 is inserted into one side of the second insertion block 15. The first spring 4 can push the second insertion block 15, which in turn pushes the rod 3. The rod 3 can connect the second insertion block 15 and the first insertion block 2, thereby ensuring accurate positioning of the blade 12 and guaranteeing the stability of the installation. This ensures the working efficiency and cutting quality of the chipper. At the same time, the blade holder 1 and the blade 12 can be separated, and the blade 12 can be disassembled and replaced individually to reduce replacement costs.
[0026] The inner walls of the drive frame 5 are fixedly connected to both sides of the second spring 6. One end of the second spring 6 is fixedly connected to the outer frame 7. The outer frame 7 can limit the upper and lower sides of the first plug-in block 2 and the second plug-in block 15 to ensure the stability of their connection. The second spring 6 can connect the outer frame 7 to the drive frame 5.
[0027] A protective block 8 is fixedly connected to one side of the outer frame 7. The protective block 8 is made of silicone. The inner wall of the protective block 8 fits against the outer surface of the blade 12, which can improve the stability of the connection between the outer frame 7 and the blade 12 and reduce the possibility of the blade 12 breaking.
[0028] The outer frame 7 is located in the middle of the second spring 6 and is rotatably connected to a bolt 10 via a bearing 9. The outer surface of the bolt 10 is threadedly connected to the front surface of the drive frame 5. By rotating the bolt 10, the position of the drive frame 5 can be controlled so as to limit and fix the position of the drive frame 5 and prevent the insertion rod 3 from disengaging from the first insertion block 2.
[0029] A connecting block 11 is fixedly connected to one side of the force plate 14, and a blade 12 is fixedly connected to one side of the connecting block 11. A groove is provided on one side of the connecting block 11, and one side of the second plug-in block 15 is slidably connected to the inside of the groove. The connecting block 11 can increase the area that the blade 12 can connect to.
[0030] A slot is provided on the other side of the tool holder 1. A sliding groove is provided on the inner wall of the slot. A fastening pad 13 is engaged inside the sliding groove. The slot makes it easier to align the tool holder 1 during installation, thereby improving the convenience and accuracy of replacement. The fastening pad 13 can increase the friction between the tool holder 1 and the connection point, improve the stability during connection, and facilitate the use of a separate fixing bolt for fixation.
[0031] Working steps: First, the tool holder 1 is engaged with the connection point via the slot. The fastening pad 13 enhances the tightness of the engagement. Then, a fixing bolt is used to fix the tool holder 1. Next, the threaded bolt 10 is turned to move the drive frame 5 outward. The drive frame 5 allows the second insertion block 15 to compress the first spring 4. Next, the second insertion block 15 is inserted into one side of the first insertion block 2. Then, the threaded bolt 10 is turned to push the insertion rod 3 into the interior of the first insertion block 2 via the second insertion block 15. This connects the second insertion block 15 and the first insertion block 2. Finally, the tool holder 1 and the blade 12 can be disassembled and the blade 12 can be removed and replaced separately to reduce replacement costs.
[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
