[0034] 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.

[0035] like Figure 1-13 As shown:

[0036] A combined pulverizing blade for a grain pulverizer, including a blade holder 101;

[0037] Mounting hole 102 is opened in the center of tool holder 101. Mounting hole 102 has a multi-shape structure design.

[0038] Multiple sets of blades 103 are provided and are evenly distributed on the outer side of the blade holder 101. The blades 103 can be designed with multiple shapes.

[0039] A circular ring 104 is disposed outside the tool holder 101 and is connected to one end of a plurality of blades 103.

[0040] In this implementation scheme: the grain crusher uses a combination crushing blade. When in use, the mounting hole 102 on the blade holder 101 can be installed on the output shaft of the drive mechanism. The drive mechanism drives the blade holder 101 to rotate, which in turn drives the blade 103 and the circular ring 104 to rotate synchronously to crush the grain.

[0041] The circular ring 104 provides structural stability. The circular ring 104 is concentric with multiple sets of blades 103. The design of the circular ring 104 effectively enhances the support of the blades 103 during high-speed rotation, greatly reducing vibration or movement caused by lack of support, thereby ensuring the accuracy and stability of the crushing operation. The enhanced support structure ensures that the force on the blades 103 is evenly distributed during high-speed rotation, avoiding stress concentration caused by uneven force, reducing the risk of deformation and damage to the blades 103. The uniform load distribution reduces wear and damage to the blades 103 during high-speed rotation, improving the durability of the blades 103.

[0042] It should be noted that the crushing tool 100 consists of a tool holder 101, a mounting hole 102, a blade 103, and a circular ring 104.

[0043] Furthermore;

[0044] In an optional embodiment, the tool holder 101 and the mounting hole 102 can be designed as an integral structure.

[0045] In this embodiment, the tool holder 101 and the blade 103 are designed as an integrated structure, which improves the overall rigidity and strength and ensures the stability of the blade 103 under high-speed rotation and high load conditions.

[0046] Furthermore;

[0047] like Figure 8-12 As shown: In an optional embodiment, the shape of the mounting hole 102 can be circular, square, hexagonal, pentagonal, rectangular, triangular, elliptical, rhomboid, star-shaped, or other shapes that can bear torque and are not prone to slippage.

[0048] In this embodiment, the shape of the mounting hole 102 can be circular, square, hexagonal, pentagonal, rectangular, triangular, elliptical, rhomboid, or star-shaped. Circular mounting hole 102 is the most common and simplest shape, easy to manufacture and install, and can provide uniform support and rotation. Alternatively, if the mounting hole 102 is square, hexagonal, pentagonal, rectangular, or triangular, it can provide multiple sets of positioning surfaces, which helps to provide good support and prevent rotation, increasing connection stability and rigidity.

[0049] It should be noted that the specific shape of the output shaft of the drive mechanism is adapted to the shape of the mounting hole 102. The shape of the output shaft can be flexibly designed according to the different shapes of the mounting hole 102.

[0050] Furthermore;

[0051] like Figure 2-6 As shown: In an optional embodiment, the blade 103 may be designed as a single-line, three-group, four-group, five-group, six-group, or eight-group blade.

[0052] In this embodiment, the blade 103 can be designed as a single-section blade, or blades in three, four, five, six, or eight sections. A single-section blade 103 is simple and easy to install, suitable for machining applications requiring straight-line cutting or wider widths. It provides good visibility and operating space, facilitating operation and maintenance. Multiple blade sections 103, such as three, four, five, six, and eight sections, provide higher stability and balance, suitable for high-speed rotation and high-precision machining applications. It can provide more uniform cutting force and reduce vibration.

[0053] Furthermore;

[0054] In an alternative embodiment, the blade 103 may be wavy in shape.

[0055] In this embodiment: when the blade 103 is designed with a wave-shaped structure, the wave-shaped blade can provide more contact points during cutting, which helps to improve cutting speed and efficiency, and can reduce the direct contact area with the material, thereby reducing the wear rate.

[0056] In an alternative embodiment, the blade 103 may be flat overall.

[0057] In this embodiment: when the blade 103 has a flat structure design, the flat design provides a more stable cutting surface, which helps to improve cutting accuracy.

[0058] In an alternative embodiment, the blade 103 may be serrated overall.

[0059] In this embodiment: when the blade 103 is designed with a serrated structure, the serrated blade can cut into the material more easily, especially when cutting harder grains. The serrated blade can reduce the contact area with the material, thereby reducing wear.

[0060] In addition, the blade 103 as a whole can also be other shapes that are conducive to increasing the rubbing area, not limited to wavy, flat and serrated shapes.

[0061] Furthermore;

[0062] In an optional embodiment, multiple sets of blades 103 may be welded to a circular ring 104.

[0063] In this embodiment, multiple sets of blades 103 can be welded to the circular ring 104. After multiple sets of blades 103 are welded to the circular ring 104, they form an integral structure, which can improve the rigidity and stability of the entire blade 103 and reduce the vibration and sway that may occur during high-speed rotation.

[0064] Furthermore;

[0065] In an optional embodiment, multiple sets of blades 103 may be bolted to a circular ring 104.

[0066] In this embodiment: multiple sets of blades 103 can be connected to the circular ring 104 by bolts. Circular countersunk holes are provided at corresponding positions of the blades 103 and the circular ring 104, and a connecting piece is provided between the blades 103 and the circular ring 104. The connecting piece has a circular hole corresponding to the circular countersunk hole. The bolt passes through the circular countersunk hole and the circular hole and is screwed to the nut. The bolt head is located below the blades 103 and the circular ring 104. The bolt connection allows for quick replacement of worn or damaged blades 103 or circular rings 104 without the need for overall replacement, reducing usage costs.

[0067] In an alternative embodiment, multiple sets of blades 103 may be riveted to a circular ring 104.

[0068] In this embodiment: multiple sets of blades 103 can be riveted to circular rings 104. First circular countersunk holes are provided at corresponding positions of blades 103 and circular rings 104, and a connecting piece is provided between blades 103 and circular rings 104. A second circular countersunk hole corresponding to the first circular countersunk hole is provided on the connecting piece. The tail of the rivet is struck or pushed by a rivet gun or hammer to expand and fill the first and second circular countersunk holes. Riveting can provide a higher connection strength than bolting because the rivet expands during riveting, thereby forming a tight connection. This can prevent the blades 103 from falling off during use. The connection has good vibration resistance, which is especially important for the high-speed rotating blade 103 assembly, and can prevent loosening and wear caused by vibration.

[0069] The working principle and usage process of this utility model: This grain crusher uses a combined crushing blade. During use, the mounting holes 102 on the blade holder 101 allow it to be installed at the output end of the drive mechanism. The drive mechanism drives the blade holder 101 to rotate, which in turn drives the blades 103 and the circular ring 104 to rotate synchronously, thus crushing the grains. The circular ring 104 provides structural stability. The circular ring 104 and multiple sets of blades 103 are concentric. The design of the circular ring 104 effectively enhances the support of the blades 103 during high-speed rotation, greatly reducing vibration or movement caused by lack of support, thereby ensuring the accuracy and stability of the crushing operation. The enhanced support structure ensures that the force on the blades 103 is evenly distributed during high-speed rotation, avoiding stress concentration caused by uneven force, reducing the risk of deformation and damage to the blades 103. The uniform load distribution reduces wear and damage to the blades 103 during high-speed rotation, improving the durability of the blades 103.

[0070] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
