Abstract
Description
Technical Field
[0001] This invention relates to the field of crushing equipment technology, and in particular to a modular assembly crusher. Background Technology
[0002] A crusher is a machine that crushes large solid raw materials to a required size. It mainly uses mechanical force to crush raw materials into smaller particles. During the crushing process, the raw materials are subjected to impact, compression, grinding, and other forces to break them into particles that meet the requirements of subsequent production processes.
[0003] Before a crusher can be put into use, it needs to be assembled. In existing technology, the assembly steps of a crusher are generally as follows: First, prepare the bearing sleeve, coupling, and retaining ring and place them inside the housing. Then, install the bearing sleeve onto the rotor shaft according to the drawings, connect one end of the coupling to the rotor shaft and the other end to the motor shaft. Next, install the retaining ring onto the rotor shaft to fix the position of the bearing sleeve and coupling. Then, install the motor, connect the motor output shaft to the rotor shaft, and adjust the position of the motor and rotor shaft to ensure they can cooperate and operate correctly. Finally, conduct a trial run to check whether the installation of the bearing sleeve, coupling, and retaining ring is correct and whether there is any looseness or abnormal noise. Only after confirming that everything is correct can the crusher be put into use.
[0004] It is evident that accurate installation of components inside the crusher casing is a prerequisite for the crusher to be put into use. However, the assembly method of assembling components inside the casing is limited by the operating space, making the assembly process difficult and cumbersome. This not only increases the probability of assembly errors but also makes it more difficult to adjust the position and angle of incorrectly assembled components, resulting in reduced assembly efficiency of the crusher and affecting the crushing operation. Summary of the Invention
[0005] This invention provides a modular assembly crusher to solve the technical problem in the prior art where assembling parts inside the crusher housing makes the assembly process more difficult and cumbersome, thereby increasing the probability of assembly errors and the difficulty of adjusting the position and angle of the parts.
[0006] To solve the above problems, the modular assembly crusher provided by the present invention adopts the following technical solution:
[0007] A modular assembly crusher, comprising:
[0008] The chassis houses the crushing module and serves to provide support and protection for the crushing module, as well as isolate the noise generated during the crushing process.
[0009] The crushing module is installed inside the chassis. The crushing module includes a cutter structure, a front bearing, a bearing sleeve, and a coupling. One end of the coupling is connected to the cutter structure, and the bearing sleeve is connected to the end of the coupling near the cutter structure.
[0010] A power module is installed outside the chassis. The power module includes a motor, and the output end of the motor is connected to the end of the coupling that is away from the cutter structure.
[0011] The cutting structure, the front bearing, the bearing sleeve, and the coupling are assembled outside the chassis to form the crushing module, which is used to be completely fed into the chassis for installation in one go.
[0012] The advantages of the modular assembly crusher provided by this invention are as follows: by assembling the cutting structure with components such as the front bearing, bearing sleeve, and coupling outside the machine casing to form a crushing module, and then sending the crushing module completely into the machine casing for installation at once, the machine casing provides support and protection for the crushing module and isolates the noise generated by the crushing module during the crushing process. The machine casing and the crushing module together form a crushing chamber for crushing raw materials; then, a power module is installed outside the machine casing, and the output end of the motor in the power module is connected to the end of the coupling away from the cutting structure to provide crushing power for the crushing module.
[0013] In this invention, the crushing module is prefabricated and assembled outside the casing. This assembly method provides ample operating and movement space for the crushing module, reducing the impact of space limitations on the assembly process and mitigating safety hazards caused by insufficient assembly space. This is beneficial for ensuring the safety of workers. Furthermore, assembling the crushing module in a larger space facilitates the adjustment of the position and angle of components during assembly, shortening the assembly time and improving the accuracy and efficiency of the crushing module assembly. In summary, this invention effectively solves the technical problems of existing technologies where assembling components inside the crusher casing makes the assembly process more difficult and cumbersome, thus increasing the probability of assembly errors and the difficulty of adjusting the position and angle of components.
[0014] Furthermore, the cutting structure includes a blade holder, which includes a central rotating shaft and a blade holder sleeved on the central rotating shaft, and a main cutting blade is mounted on the blade holder.
[0015] Furthermore, the chassis is equipped with a secondary cutter assembly facing inwards. The secondary cutter assembly includes a cutter cover plate connected to the chassis, on which a secondary cutter is fixedly mounted. The secondary cutter cooperates with the main cutter to cut the material entering the chassis.
[0016] Furthermore, the secondary cutter and the cutter cover plate are provided with corresponding pin holes and bolt holes. The secondary cutter is precisely installed on the cutter cover plate by inserting a positioning pin into the pin hole, and the secondary cutter is locked to the cutter cover plate by screwing a bolt into the bolt hole.
[0017] Furthermore, the coupling is connected to the central rotating shaft.
[0018] Furthermore, the outer periphery of the bearing sleeve is provided with a plurality of protrusions protruding from its surface, and the end of the coupling connected to the bearing sleeve has a groove that matches the protrusions. The protrusions and the grooves cooperate to quickly and accurately assemble the bearing sleeve and the coupling.
[0019] Beneficial effects: By setting multiple protrusions on the outer circumference of the bearing sleeve and setting grooves on the coupling to match the multiple protrusions, the protrusions can be freely inserted into the grooves without affecting the use of the bearing, and the positioning can be provided for the accurate installation of the bearing sleeve on the coupling, thus improving the installation efficiency of the bearing sleeve and the coupling.
[0020] Furthermore, the coupling is either a rigid coupling or a flexible coupling.
[0021] Furthermore, the coupling is a plum blossom coupling.
[0022] Furthermore, the chassis is connected to the plum blossom coupling by bolts.
[0023] Furthermore, both ends of the central rotating shaft are provided with shaft retaining rings to prevent it from shifting during operation and to lock the front bearing. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0032] It should be noted that the main concept of the modular assembly crusher provided by this invention is as follows: by assembling the cutting structure, front bearing, bearing sleeve, and coupling, etc., outside the casing to form a crushing module, the assembly space outside the casing is more spacious, providing more operating and movement space for the crushing module assembly. This facilitates precise alignment and angle adjustment between components during assembly, reduces the probability of assembly errors, and greatly improves the installation efficiency of the crushing module, thereby increasing the overall installation efficiency of the crusher. After the crushing module is installed, it is completely inserted into the casing for installation. Then, the power module is installed outside the casing, and the output end of the motor in the power module is connected to the end of the coupling away from the cutting structure. The motor provides crushing power to the crushing module to ensure the crushing operation. Through the above configuration, this invention effectively solves the technical problem in the prior art where assembling components inside the crusher casing makes the assembly process more difficult and cumbersome, thus increasing the probability of assembly errors and the difficulty of adjusting the position and angle of components.
[0033] After introducing the basic principles of the present invention, various non-limiting embodiments of the present invention are described in detail below. Any number of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.
[0034] The principles and spirit of the present invention will be explained in detail below with reference to several representative embodiments.
[0035] A pulverizer is a machine that crushes large solid raw materials to a required size. It primarily uses mechanical force to break down raw materials into smaller particles. During the pulverizing process, the raw materials are broken into particles that meet the requirements under the action of impact, compression, and grinding forces to satisfy the needs of subsequent production processes.
[0036] Before a crusher can be put into use, it needs to be assembled. Accurate installation of the components inside the crusher's casing is a prerequisite for its operation. However, traditional assembly methods, which involve assembling components inside the casing, are limited by operating space, making the assembly process difficult and cumbersome. This not only increases the probability of assembly errors but also makes adjusting the position and angle of incorrectly assembled components more difficult, leading to reduced assembly efficiency and hindering crushing operations. Therefore, there is an urgent need to provide a new type of crusher to solve the technical problems of existing technologies that make the assembly process more difficult and cumbersome, thus increasing the probability of assembly errors and the difficulty of adjusting the position and angle of components.
[0037] Example 1 of the modular assembly crusher provided by this invention:
[0038] like Figures 1 to 4 As shown, the modular assembly crusher includes a casing 1, a crushing module, and a power module. The crushing module is installed inside the casing 1, which provides support and protection for the crushing module and isolates it from noise generated during the crushing process. The power module is installed outside the casing 1 and connected to the crushing module, providing the crushing power to the crushing module.
[0039] Regarding the crushing module: The crushing module includes a cutter structure, a front bearing, a bearing sleeve 2, and a coupling. The cutter structure includes a cutter holder, which includes a central rotating shaft 5 and three annular cutter holders 6 sleeved on the central rotating shaft 5. A main cutter 7, made of tungsten steel, is obliquely welded onto the cutter holder 6, and its extension direction forms an angle of 5° with the extension direction of the central rotating shaft 5. The front bearing is a ball bearing 17, which is installed inside the bearing sleeve 2. The coupling is either a rigid coupling or a flexible coupling, with the right end of the coupling connected to the left end of the central rotating shaft 5. The bearing sleeve 2 is installed on the right end of the coupling, i.e., the end of the coupling connected to the central rotating shaft 5.
[0040] Specifically, the left and right ends of the central rotating shaft 5 are provided with shaft retaining rings 14. The shaft retaining rings 14 are used to prevent the central rotating shaft 5 from running after vibrating left and right during the operation of the crusher, and at the same time, they play a locking role for the ball bearings 17.
[0041] Specifically, the coupling is a plum blossom coupling 3, which is connected to the housing 1 by bolts 11. The outer circumference of the bearing sleeve 2 is provided with four protruding blocks 12. The right end of the plum blossom coupling 3, i.e., the end where the plum blossom coupling 3 is fitted onto the bearing sleeve 2, has four grooves 13 that match the protruding blocks 12. The protruding blocks 12 and the grooves 13 cooperate with each other, allowing the protruding blocks 12 to be freely inserted into the grooves 13 without affecting the use of the ball bearing 17. This also provides positioning for the accurate installation of the bearing sleeve 2 on the plum blossom coupling 13, improving the installation efficiency of the bearing sleeve 2 and the plum blossom coupling 3.
[0042] Regarding the power module: The power module includes motor 4, the output of which is connected to the left end of the plum blossom coupling 3. Specifically, motor 4 is a single-phase DC motor (220V) with a synchronous speed of 1500 rpm, an output power of 750W, and a torque of 4.775 N·m.
[0043] In addition, a secondary cutter assembly is fixedly installed on the inner side wall of the chassis 1. The secondary cutter assembly includes a cutter cover plate 8 connected to the chassis 1, and a secondary cutter 9 is fixedly installed on the cutter cover plate 8. The secondary cutter 9 cooperates with the main cutter 7 to cut the material entering the chassis 1.
[0044] Specifically, the cutter cover plate 8 is a rectangular plate. Two rows of corresponding bolt holes 15 are provided on both the secondary cutter 9 and the cutter cover plate 8. Bolts 11 are screwed into the bolt holes 15 to lock the secondary cutter 9 to the cutter cover plate 8, preventing displacement of the secondary cutter 9 during long-term cutting. Two corresponding pin holes 16 are also provided on both the secondary cutter 9 and the cutter cover plate 8. Cylindrical positioning pins 10 are inserted into the pin holes 16 to achieve precise installation and fixation of the secondary cutter 9 on the cutter cover plate 8. It should be noted that when installing the secondary cutter 9, the arc surface of the secondary cutter 9 must first be tightly fitted with the arc surface of the main cutter 7 before tightening the bolts on the cutter cover plate 8 to ensure the cutting edge relationship between the main cutter 7 and the secondary cutter 9.
[0045] Finally, it should be noted that the cutting structure, ball bearing 17, bearing sleeve 2, and plum blossom coupling 3 are assembled outside the chassis 1 to form a crushing module, which is used to be completely fed into the chassis 1 for installation in one go.
[0046] The working principle of the modular assembly crusher provided by this invention is as follows: First, the blade holder 6 is fixedly installed on the central rotating shaft 5, and then the main cutter 7 is welded to the blade holder 6 to form a cutter structure; then, the cutter structure is assembled with the ball bearing 17, bearing sleeve 2, plum blossom coupling 3, and shaft retaining ring 14 to form a crushing module; then, the crushing module is fed into the machine box 1 from the left side at once, and the arc surface of the main cutter 7 is tightly fitted with the arc surface of the auxiliary cutter 9 installed inside the machine box 1. After fitting, the bolts 11 on the cutter cover plate 8 are locked to ensure the cutting edge relationship between the main cutter 7 and the auxiliary cutter 9; finally, after the crushing module is installed in the machine box 1, the output end of the motor 4 is connected to the left end of the plum blossom coupling 3, and the right end of the plum blossom coupling 3 is locked and fixed with bolts 11, thereby completing the modular assembly of the crusher.
[0047] Embodiment 2 of the modular assembly crusher provided by the present invention:
[0048] Its main difference from Example 1 is:
[0049] In Example 1, the coupling is a plum blossom coupling.
[0050] In this embodiment, the coupling is a serpentine spring coupling.
[0051] Embodiment 3 of the modular assembly crusher provided by the present invention:
[0052] Its main difference from Example 1 is:
[0053] In Example 1, the motor is a single-phase DC motor with a voltage of 220V, a synchronous speed of 1500 rpm, an output power of 750W, and a torque of 4.775 N·m.
[0054] In this embodiment, the motor speed is selected based on the specific cutting amount. If the cutting amount is large, a high-speed motor can be selected; if the cutting amount is small, a low-speed motor can be selected.
[0055] Based on the above description in this specification, those skilled in the art will also understand that terms used, such as "upper," "left," "right," "inner," and "outer," which indicate orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings of this specification. They are only for the purpose of facilitating the explanation of the present invention and simplifying the description, and do not explicitly or implicitly suggest that the device or element involved must have the specific orientation, or be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as a limitation on the present invention.
[0056] In addition, in the description of this specification, "multiple" means at least two, such as two, three or more, etc., unless otherwise expressly and specifically defined.
