Description

Technical Field

[0001] The invention relates to the technical field of crushing knives, in particular to a polygonal environmentally friendly crushing knife. Background Art

[0002] The polygonal environmentally friendly crushing knife is a specially designed crushing tool with a unique structure and polygonal characteristics. When in use, sensors such as displacement sensors, pressure sensors and temperature sensors are installed at key positions of the polygonal environmentally friendly crushing knife. These sensors can monitor the working status of the crushing knife in real time, such as cutting depth, cutting force and working temperature, making it more intelligent and automated, making it suitable for a variety of crushing operations, especially in the field of environmental protection. It shows significant advantages and is widely used in various occasions that require crushing processing, especially in the field of environmental protection, such as waste recycling, garbage disposal, etc. Its efficient crushing ability and environmental protection characteristics make it an indispensable tool in these fields.

[0003] When the existing crushing knife is in use, the number of blades is fixed. The fixed number of blades leads to uneven distribution of materials in the crushing chamber. Some materials may not be effectively crushed, which affects the crushing efficiency and quality. The number of blades cannot be changed according to actual needs, and the fixed number of blades cannot flexibly adjust the crushing capacity and crushing effect according to actual needs. When the crushing efficiency needs to be improved, it cannot be achieved by increasing the number of blades, and when the energy consumption needs to be reduced, the goal cannot be achieved by reducing the number of blades.

[0004] When the crushing knife is in use, it is generally fixed in place by bolts and other structures. If the tightening force of the bolts is insufficient or the connection structure is unreasonable, the crushing knife may fall off during use, causing a safety accident. The fixation method using only bolts and other connection structures may limit the flexibility of the crushing knife in design and use, making it unable to adapt to materials of different types, hardness and sizes. Insufficient connection strength may also cause other parts of the equipment (such as bearings, transmission devices, etc.) to bear excessive loads, thereby accelerating the overall wear and aging of the equipment.

[0028] Among them, through the meshing transmission of the first internal gear 4 and the second internal gear 5, the precise rotation control of the connecting disk 3 and the retracting mechanism 24 connected thereto relative to the cutter disc 1 is realized. This design makes the deployment and storage operations of the blade 11 simpler and more stable. At the same time, the close fit between the limit disk 7 and the inside of the cutter disc 1, and the flexible rotation of the rotating block 10 on the fixed shaft 9, together ensure the stability and reliability of the blade 11 during the extension and retraction process, and avoid operational errors caused by shaking or misalignment. The threaded connection design of the limit screw 12 not only achieves a firm fixation between the connecting disk 3 and the cutter disc 1, but also provides a convenient adjustment method, allowing the user to adjust the working state of the blade 11 as needed, such as locking the position of the blade 11 or making fine adjustments, thereby enhancing the applicability and flexibility of the entire device.

[0029] See also Figure 6 and Figure 7The cutter disc 1 is provided with a stabilizing mechanism 6, which includes a mounting shaft 13, a fastening spring 19, an elastic rod 20, a hinge seat 21 and an abutting rod 22. The outer surface of the mounting shaft 13 is engaged with the interior of the cutter disc 1, and the outer surface of the mounting shaft 13 is engaged with the interior of the connecting disc 3. A sliding groove 18 is provided inside the mounting shaft 13.

[0030] Among them, the mounting shaft 13 is clamped with the inside of the cutter disc 1 and the connecting disc 3 to form a stable supporting structure. This design not only enhances the connection strength between the connecting disc 3 and the cutter disc 1, but also ensures the stability of the entire retracting mechanism 24 during operation. At the same time, the combined use of the sliding groove 18, the tightening spring 19, the elastic rod 20 and the hinge seat 21 enables the abutment rod 22 to abut against the cutter disc 1, thereby further stabilizing the connection between the connecting disc 3 and the cutter disc 1.

The setting of the plug-in groove 14 and the threaded groove 15 makes it more stable when connected to external connecting components.

[0031] See also Figure 1 and Figure 2 The outer surface of the cutter disc 1 is provided with a cutting edge 2.

[0032] Among them, through the use of the blade 2, the material can be crushed efficiently and conveniently when the crushed material does not require additional crushing, thereby saving energy consumption.

[0033] Working principle: when in use, when the whole is connected and stabilized, the installation shaft 13 can be first inserted into the inside of the cutter disc 1 and the connecting disc 3, and then the abutment rod 22 can be pressed to take the abutment rod 22 out of the inside of the rectangular groove 23, and then the abutment rod 22 can be rotated in the direction through the action of the hinge seat 21, and then the abutment rod 22 can be loosened. The abutment rod 22 can be fixed between the abutment rod 22 and the inside of the sliding groove 18 through the power action of the fastening spring 19 and the elastic rod 20, so that the position of the abutment rod 22 can be abutted against the right side of the cutter disc 1, and then the installation The surface of the shaft 13 is provided with a threaded ring 16, and the outer surface of the threaded ring 16 is installed with an abutment bolt 17, and the right side of the abutment bolt 17 is abutted against the left side of the cutter disc 1 to ensure stability during use. Finally, the external connecting piece is connected to the plug-in groove 14 opened inside the installation shaft 13. After the connection is completed, the threaded groove 15 opened inside the installation shaft 13 can be used to thread the threaded groove 15, the installation shaft 13 and the external connecting piece. Fastening screws are connected to ensure the tightness of the cutter disc 1 during use and prevent the cutter disc 1 from falling off the equipment during use.

[0034] When the number of blades 11 is changed, the abutment rod 22 can be pressed to separate the left side of the abutment rod 22 from the right side of the cutter disc 1, and then the connecting disc 3 can be rotated to mesh the first internal gear 4 set inside the connecting disc 3 with the second internal gear 5 set inside the cutter disc 1, thereby driving the limit disc 7 to rotate. When the limit disc 7 rotates, the rotating block 10 fixedly installed on the left side of the limit disc 7 can rotate on the outer surface of the fixed shaft 9. When the rotating block 10 rotates, the left side of the rotating block 10 can be abutted against the inclined surface of the blade 11, so that the position of the blade 11 is separated from the inside of the cutter disc 1, and one side of the blade 11 is exposed to the outer ring of the cutter disc 1. Then, one side of the abutment rod 22 can be pulled to abut one side of the abutment rod 22 against the right side of the cutter disc 1, so that the position of the blade 11 is more stable. Finally, through the action of the limiting screw 12, the outer surface of the limiting screw 12 is connected to the internal threads of the cutter disc 1 and the connecting disc 3, so that the position of the blade 11 after moving out of the cutter disc 1 is further stabilized, thereby ensuring stability during crushing.
