According to the utility model, the plurality of crushing mechanisms which are sequentially staggered are arranged on the rotating shaft, so that the blades can uniformly occlude materials in the crushing process, and the damage to the blades caused by overlarge single-point stress is avoided. Besides, the blade is fixed by adopting a hidden mounting mechanism, so that the exposure of screws is effectively reduced, the risk of accidental injury in operation is reduced, and the anti-loosening performance is improved by increasing the contact area. Meanwhile, due to the design of anti-skid textures on the surface of the rotating shaft, slippage or dislocation of the supporting seat is further prevented, and the stability and safety of the equipment under high-load operation are ensured. According to the utility model, the operation reliability and the service life of equipment are obviously improved.

Description

Technical Field

[0001] The utility model relates to the technical field of mechanical engineering, in particular to a heavy-duty crusher with high-efficiency biting, anti-fracture and impact-resistant performance. Background Art

[0002] In the design and use of heavy-duty crushing equipment, especially when processing high-hardness materials, the durability and impact resistance of crusher blades have always been a technical difficulty in the industry. For example:

[0003] 1. Traditional crushers typically crush materials by placing multiple blades on a rotating shaft. However, in this structure, the blades are susceptible to concentrated stress during rotation, resulting in uneven force and breakage or wear during operation, shortening the equipment's service life. Furthermore, due to the high vibration of the equipment during crushing, the connection between the blades and the supporting structure can easily loosen due to vibration, resulting in poor operational stability.

[0004] 2. Existing techniques typically enhance blade material or thickness to improve impact resistance. While this approach reduces blade breakage to a certain extent, due to limitations in the overall structural design, the blades can still be damaged by excessive concentrated stress. Furthermore, thickening the blade increases energy consumption and reduces crushing efficiency.

[0005] 3. Regarding equipment connection, some existing technologies use tighter connections to reduce blade loosening caused by vibration. However, when facing long-term high-load operation, there is still a risk of loosening between the blade and the support seat, especially in high-vibration environments, where this loosening problem is more significant.

[0006] Furthermore, existing technologies often use external bolts or other fasteners to connect the blade to the support base. While this design facilitates installation and disassembly, it also introduces new safety hazards. Because the bolts are typically exposed, they are prone to accidental damage during operation, especially when the equipment is running at high speeds. Exposed bolts increase the risk of operator injury. Furthermore, the exposed portions of the external bolts are susceptible to wear and corrosion after prolonged use, further increasing the risk of bolt loosening and breakage, thereby impacting the overall performance and safety of the equipment.

[0007] Therefore, how to effectively avoid the breakage of the blade caused by uneven force, reduce the loose connection and improve the operational safety has become the technical problem to be solved by the present utility model. Utility Model Content

[0008] The technical problem solved by the present invention is to address the defects existing in the above-mentioned prior art and provide a heavy-duty crusher with efficient bite and anti-fracture and impact resistance performance, so as to solve the problems of uneven force on the blades, loose connections and operational safety hazards raised in the above-mentioned background technology.

[0009] In order to solve the above technical problems, the technical solutions adopted by the present invention are as follows:

[0010] A heavy-duty crusher with efficient biting, anti-fracture and impact-resistant properties, comprising a crusher body, the crusher body comprising a funnel seat, the funnel seat comprising a funnel cavity, a rotating shaft being arranged in the funnel cavity, the rotating shaft passing through the funnel cavity and the two ends of the rotating shaft being rotatably connected to the funnel seat respectively; a plurality of crushing mechanisms are staggered in sequence in the axial direction of the rotating shaft, the crushing mechanism comprising a triangular support seat, the triangular support seat being sleeved on the rotating shaft and fixedly connected to the rotating shaft, the triangular support seat comprising three corners, each corner being provided with a knife claw formed by a protrusion, the knife claw being fixedly connected to a blade, and the blade being distributed in a staggered manner on the rotating shaft through the knife claw.

[0011] As a further solution of the present invention, the blade is fixedly connected to the knife claw through a hidden mounting mechanism, and the hidden mounting mechanism includes an installation avoidance groove, which is arranged on the surface of the knife claw, and a threaded hole is provided at the bottom of the installation avoidance groove. The bolt passes through the threaded hole and is threadedly connected to the installation screw hole on the knife claw.

[0012] As a further solution of the present invention, the number of the hidden mounting mechanisms is two, and the two hidden mounting mechanisms are symmetrically arranged on both sides of each claw, so that the blade is installed on the claw more firmly to reduce the risk of loosening when impacted.

[0013] As a further solution of the present invention, the three corners of the triangular support seat are evenly distributed on the periphery of the rotating shaft, and the raised parts of the claws are distributed at an angle of 120 degrees, so that the blade is evenly stressed when driven by the rotating shaft, thereby reducing the impact of unbalanced vibration on the equipment.

[0014] As a further solution of the present invention, the blade and the claw are installed through a tightly fitting fixed connection structure, and the fixed connection structure includes bolts and threaded holes to ensure that the blade and the claw maintain a stable relative position during rotation.

[0015] As a further solution of the present invention, the surface of the rotating shaft is provided with an anti-slip texture or anti-slip coating to increase the friction between the triangular support seat and the rotating shaft to prevent the triangular support seat from sliding or dislocating during rotation.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. Multiple crushing mechanisms are staggered on the rotating shaft, allowing the blades' multiple corners to be fully exposed and utilized. This design effectively increases the number of cutting positions and corners where the blades come into contact with the material, ensuring multi-directional and multi-angle cutting during the crushing process, achieving more uniform and efficient crushing. Furthermore, the multiple staggered blades prevent rapid wear or damage to the blades caused by a single force point during the crushing process, further enhancing the stability and service life of the equipment.

[0018] 2. Multiple, sequentially staggered crushing mechanisms ensure that the blades engage the material evenly during the crushing process, preventing blade breakage or damage due to excessive force at a single point. In particular, the triangular support design evenly distributes the raised portions of the blades at a 120-degree angle, further enhancing the stability of the equipment during operation and reducing equipment wear and tear caused by unbalanced vibration.

[0019] 3. The blade is fixed with a concealed mounting mechanism, which not only ensures the blade is secure but also effectively reduces the exposed screw area, thereby reducing the risk of accidental damage during operation. In addition, this mounting method further improves the blade's resistance to loosening under high impact by increasing the contact area of the mounting area.

In an embodiment of the utility model, a heavy-duty crusher with efficient biting, anti-fracture and impact-resistant properties includes a crusher body 1, the crusher body 1 includes a funnel seat 2, the funnel seat 2 includes a funnel cavity 3, a rotating shaft 4 is provided in the funnel cavity 3, the rotating shaft 4 passes through the funnel cavity 3 and the two ends of the rotating shaft 4 are respectively connected to the funnel seat 2 for rotation; a plurality of crushing mechanisms are staggered in sequence in the axial direction of the rotating shaft 4, the crushing mechanism includes a triangular support seat 5, the triangular support seat 5 is sleeved on the rotating shaft 4 and fixedly connected to the rotating shaft 4, for example, the triangular support seat 5 can be an integrated structure with the rotating shaft 4, which are all extended implementation methods known to ordinary technicians in this field; the triangular support seat 5 includes three corners, each corner is provided with a protruding claw 6, the claw 6 is fixedly connected to the blade 7, and the blade 7 is distributed on the rotating shaft 4 in a staggered manner through the claw 6.

[0030] The blade 7 is fixedly connected to the claw 6 via a concealed mounting mechanism. This mechanism includes a mounting clearance groove 8, which is provided on the surface of the claw 6. The bottom of the mounting clearance groove 8 is provided with a threaded hole 9, through which a bolt passes and is threadedly connected to the mounting screw hole on the claw 6. There are two concealed mounting mechanisms, symmetrically arranged on either side of each claw 6, making the installation of the blade 7 on the claw 6 more stable and reducing the risk of loosening during impact. The three corners of the triangular support 5 are evenly distributed on the periphery of the rotating shaft 4, and the raised portions of the claw 6 are distributed at a 120-degree angle, so that the blade 7 is evenly stressed when driven by the rotating shaft 4, thereby reducing the impact of unbalanced vibration on the equipment.

[0031] The blade 7 and the claw 6 are mounted together via a tightly fitting fixed connection structure comprising bolts and threaded holes 9, ensuring that the blade 7 and the claw 6 maintain a stable relative position during rotation. The surface of the rotating shaft 4 is provided with an anti-slip texture or coating to increase friction between the triangular support 5 and the rotating shaft 4, thereby preventing the triangular support 5 from slipping or misaligning during rotation.

[0032] Example 1:

[0033] This embodiment relates to a heavy-duty crusher with efficient engagement, anti-fracture, and impact-resistant properties. This crusher is particularly suitable for processing high-hardness materials such as construction waste, ore, and other complex materials. When processing such materials, conventional crushers are prone to blade breakage due to uneven force due to design limitations. Furthermore, in high-frequency vibration environments, the connection between blade 7 and the supporting structure can easily loosen, affecting the stability and service life of the equipment.

[0034] In this embodiment, the crusher includes a rotating shaft 4, on which a plurality of crushing mechanisms are staggered in sequence. Each crushing mechanism includes a triangular support base 5, on which three knife claws 6 are evenly distributed, and blades 7 are fixed to the knife claws 6. When the crusher is in operation, the rotating shaft 4 drives the blades 7 to rotate at high speed, and the blades 7 engage with the material to achieve efficient crushing. During this process, due to the staggered design of the crushing mechanism, the blades 7 can evenly engage the material, effectively avoiding breakage or damage to the blades 7 due to excessive force at a single point. This design is particularly suitable for processing large and hard materials, significantly improving the crushing efficiency and durability of the equipment.

[0035] This embodiment also uses a hidden mounting mechanism to firmly fix the blade 7 on the claw 6. This mounting mechanism reduces the exposed part of the screw by providing an avoidance groove on the surface of the claw 6 and installing the bolt in a hidden manner, thereby reducing the risk of the operator being injured by contact with the screw during the operation of the equipment. In addition, since the hidden mounting mechanism further improves the anti-loosening performance of the blade 7 under high impact by increasing the contact area of the mounting part, it ensures that the blade 7 can still maintain a stable relative position under high-speed rotation and high-load conditions, prevents the blade 7 from loosening or falling off, and ensures the long-term stable operation of the equipment. In addition, in this embodiment, an anti-slip texture or coating known to ordinary technicians in this field can be provided on the surface of the rotating shaft 4 to enhance the friction between the triangular support seat 5 and the rotating shaft 4, so as to prevent the support seat from slipping or misalignment when the equipment is running. Especially when processing high-hardness materials, the anti-slip design effectively avoids equipment shutdown or failure problems caused by the sliding of the support seat, thereby extending the continuous operation time of the equipment and reducing the need for equipment maintenance.

For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to the specific circumstances.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
