Description

Technical Field

[0001] This utility model belongs to the field of chipper blades, specifically an adjustable chipper blade. Background Technology

[0002] A chipper is a type of machinery widely used in the wood processing industry. It is mainly used to cut logs or other woody materials into thin slices. The flying knife is one of the key components of the chipper, and its performance directly affects the chipping quality and production efficiency.

[0003] The throwing knife is bolted to a support plate within the knife slot during installation. To adjust the knife's extension based on the log's diameter, hardness, or cutting requirements, the operator first uses a wrench to loosen the bolts, releasing the knife's position. The knife's position is then adjusted to ensure the desired height. Finally, the bolts are tightened again to re-secure the knife, thus achieving adjustment. However, in actual use, adjusting the throwing knife requires external tools, making the process cumbersome. Without external tools, adjusting the knife is difficult, reducing adjustment efficiency.

[0004] In summary, this utility model provides an adjustable chipper blade to solve the above problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] An adjustable chipper blade includes a blade plate, a blade on the top of the blade plate, and the blade plate is fixed to the inner cavity of a blade groove. A connecting groove is formed on the top of the blade plate, and a rack is fixedly connected to one side of the inner cavity of the connecting groove. Positioning holes are formed on both sides of the top of the blade plate. A knob is formed on the top of the blade, and a connecting cylinder is fixedly connected to the bottom of the knob. A sleeve is fitted onto the surface of the connecting cylinder and is fixedly connected to the blade. A spring is provided between the connecting cylinder and the sleeve. A gear is fixedly connected to the bottom of the sleeve, located in the inner cavity of the connecting groove and meshing with the rack. A connecting plate is movably connected to the bottom of the knob via a bearing, and a positioning rod is fixedly connected to the bottom of the connecting plate. The bottom of the positioning rod extends into the inner cavity of the positioning hole and is movably connected to the inner cavity of the positioning hole.

[0007] Furthermore, in this utility model, the top of the spring extends into the inner cavity of the connecting cylinder and is fixedly connected to the top of the inner cavity of the connecting cylinder, and the bottom of the spring extends into the inner cavity of the sleeve and is fixedly connected to the bottom of the inner cavity of the sleeve.

[0008] Furthermore, in this utility model, limit grooves are provided on both sides of the inner cavity of the sleeve, and limit blocks are fixedly connected to the lower ends of both sides of the surface of the connecting cylinder. The limit blocks are located in the inner cavity of the limit groove and are slidably connected to the inner cavity of the limit groove.

[0009] Furthermore, in this invention, magnets are fixedly connected to the bottom of the positioning rod and the bottom of the positioning hole cavity, and the two magnets are magnetically connected.

[0010] Furthermore, in this utility model, the bottom of the gear is movably connected to a slide rod via a bearing, the bottom of the inner cavity of the connecting groove is provided with a sliding groove, the bottom of the slide rod extends into the inner cavity of the sliding groove and is slidably connected to the inner cavity of the sliding groove.

[0011] Beneficial effects: This utility model has the following beneficial effects:

[0012] This invention features a blade plate fixed inside a blade groove, with the blade connected above the blade plate, facilitating blade disassembly and replacement. Rotating a knob rotates the connecting cylinder, sleeve, and gear. Due to the meshing of the gear and rack, the gear rotates while simultaneously moving the blade to one side, thus adjusting the blade extension.

[0019] To better understand the technical content of this utility model, specific embodiments are described below in conjunction with the accompanying drawings. Various aspects of this utility model are described in this disclosure with reference to the accompanying drawings, which illustrate numerous illustrative embodiments. The embodiments of this disclosure are not necessarily defined to include all aspects of this utility model. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in this utility model are not limited to any particular implementation. Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0020] Example 1

[0021] like Figure 1-4 The image shows the first embodiment of this utility model, which provides an adjustable chipper blade, including a blade plate 1. A blade 2 is mounted on the top of the blade plate 1, and the blade plate 1 is fixed to the inner cavity of a blade groove. A connecting groove 3 is formed on the top of the blade plate 1, and a rack 4 is fixedly connected to one side of the inner cavity of the connecting groove 3. Positioning holes 5 are formed on both sides of the top of the blade plate 1. A knob 6 is mounted on the top of the blade 2, and a connecting cylinder 7 is fixedly connected to the bottom of the knob 6. A sleeve 8 is fitted onto the surface of the connecting cylinder 7, and the sleeve 8 is fixedly connected to the blade 2. A spring 9 is provided between the connecting cylinder 7 and the sleeve 8. The bottom of the sleeve 8 is fixedly... A gear 10 is fixedly connected to the inner cavity of the connecting groove 3 and meshes with the rack 4. The connecting groove 3 provides movement space for the gear 10, and the rack 4 meshes with the gear 10, realizing the function of driving the blade 2 to move by rotating the knob 6. The bottom of the knob 6 is movably connected to the connecting plate 11 through the bearing, and the bottom of the connecting plate 11 is fixedly connected to the positioning rod 12. The bottom of the positioning rod 12 extends into the inner cavity of the positioning hole 5 and is movably connected to the inner cavity of the positioning hole 5. The positioning hole 5 and the positioning rod 12 cooperate with each other to fix the blade 2 in the designated position after adjustment.

[0022] like Figure 1-4As shown, by rotating knob 6, the connecting plate 11 and the positioning rod 12 are driven upward, causing the positioning rod 12 to disengage from the inner cavity of the positioning hole 5 and release the positioning of the blade 2. At the same time, rotating knob 6 can drive the connecting cylinder 7 and the sleeve 8 to rotate. Since the gear 10 meshes with the rack 4, the rotation of the sleeve 8 will be converted into the power of the gear 10, causing the gear 10 to move linearly on the rack 4, thereby pushing the blade 2 forward or backward to adjust the extension length of the blade 2. After adjustment, the return force of the spring 9 can drive the connecting cylinder 7, knob 6 and connecting plate 11 to reset, causing the connecting plate 11 to drive the positioning rod 12 into the inner cavity of the positioning hole 5, thereby positioning the adjusted blade 2. This achieves the adjustment operation. No external auxiliary tools are needed throughout the process. Only rotating knob 6 is needed to adjust the extension length of the blade 2, which greatly improves the adjustment efficiency.

[0023] Example 2

[0024] Reference Figure 4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0025] In this embodiment, the top of the spring 9 extends into the inner cavity of the connecting cylinder 7 and is fixedly connected to the top of the inner cavity of the connecting cylinder 7, and the bottom of the spring 9 extends into the inner cavity of the sleeve 8 and is fixedly connected to the bottom of the inner cavity of the sleeve 8.

[0026] Limiting grooves 13 are provided on both sides of the inner cavity of the sleeve 8. Limiting blocks 14 are fixedly connected to the lower ends of both sides of the surface of the connecting cylinder 7. The limiting blocks 14 are located in the inner cavity of the limiting grooves 13 and are slidably connected to the inner cavity of the limiting grooves 13.

[0027] like Figure 4 As shown, the two ends of the spring 9 are connected to the connecting cylinder 7 and the sleeve 8 respectively, which facilitates the resetting of the connecting cylinder 7 and the positioning of the blade 2 in the later stage, preventing the blade from deviating during the cutting process. The limiting groove 13 and the limiting block 14 cooperate with each other to limit the sliding range of the connecting cylinder 7 inside the sleeve 8, and also facilitate the synchronous movement of the connecting cylinder 7 and the sleeve 8.

[0028] Example 3

[0029] Reference Figure 1-4 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0030] In this embodiment, magnets are fixedly connected to the bottom of the positioning rod 12 and the bottom of the inner cavity of the positioning hole 5, and the two magnets are magnetically connected.

[0031] The bottom of the gear 10 is movably connected to the slide rod 15 via a bearing. The bottom of the inner cavity of the connecting groove 3 is provided with a slide groove 16. The bottom of the slide rod 15 extends into the inner cavity of the slide groove 16 and is slidably connected to the inner cavity of the slide groove 16.

[0032] like Figure 1-4 As shown, by setting a magnet, the connection between the positioning hole 5 and the positioning rod 12 can be made more secure, enhancing the stability of the blade 2 after positioning. When the gear 10 moves, it can drive the slide rod 15 to slide along the inner cavity of the slide groove 16, thereby limiting the gear 10 and preventing the gear 10 from disengaging from the rack 4 during movement.

[0033] In use, first pull knob 6. Knob 6 causes spring 9, connecting plate 11, and positioning rod 12 to move upward, stretching spring 9. Then, place blade 2 on top of blade plate 1. Blade 2 drives gear 10 into the inner cavity of connecting groove 3, engaging the rack 4 on one side of the inner cavity of connecting groove 3. Next, release knob 6. Spring 9 loses its stretching force, causing knob 6, connecting plate 11, and positioning rod 12 to return downward, allowing positioning rod 12 to enter the inner cavity of positioning hole 5, achieving a snap-fit. The two magnets attract each other, creating a magnetic connection, thus completing the connection and installation of blade plate 1 and blade 2. This facilitates the subsequent wood chipping operation of blade 2. When adjusting the extension length of blade 2, first pull knob 6. Knob 6 causes connecting plate 11 and positioning rod 12 to move upward. 12 is moved upwards, causing the positioning rod 12 to gradually disengage from the inner cavity of the positioning hole 5, thereby releasing the positioning of the blade 2. At the same time, rotating the knob 6 can drive the connecting cylinder 7 and the sleeve 8 to rotate. Since the gear 10 meshes with the rack 4, the rotation of the sleeve 8 will be converted into the power of the gear 10, causing the gear 10 to move linearly on the rack 4, thereby pushing the blade 2 forward or backward to adjust the extension length of the blade 2. After adjustment, the return force of the spring 9 can drive the connecting cylinder 7, the knob 6 and the connecting plate 11 to reset, so that the connecting plate 11 drives the positioning rod 12 into the inner cavity of the positioning hole 5, thereby positioning the adjusted blade 2. This achieves the adjustment operation. No external auxiliary tools are needed throughout the process. Only rotating the knob 6 is needed to adjust the extension length of the blade 2, which greatly improves the adjustment efficiency.
