Description

Technical Field

[0001] This utility model relates to the field of crusher technology, and in particular to a crushing cone fixing structure. Background Technology

[0002] A toothed roll crusher is a mechanical device that uses two relatively rotating toothed rolls to crush materials. It is mainly used for crushing brittle materials such as coal, ore, limestone, and oil shale. The crushing cone is a key component of the toothed roll crusher, directly contacting the material being crushed and bearing the crushing force. During use, it is prone to loosening and falling off, which can easily lead to accidents. Furthermore, it is a wear part that requires frequent replacement; therefore, the safety and reliability of its fixing structure are of paramount importance.

[0003] Currently, the crushing cones on the working rolls of toothed roll crushers are mostly installed directly with bolts. This can easily lead to loosening and insecure installation during operation. As a result, most users simply weld the crushing cones in place, which makes it difficult to replace them later. Utility Model Content

[0004] This application discloses a crushing cone fixing structure to solve the problems of easy loosening, insecure installation, and inconvenient replacement of crushing cones in the prior art.

[0005] To solve the above problems, the present invention adopts the following technical solution: A crushing cone fixing structure includes: Mounting holes are used to install the crushing cone; A positioning part is formed between one end of the mounting hole and the crushing cone. The positioning part is used to position the crushing cone during installation. The first connector is located inside the mounting hole and is sleeved on the crushing cone. The first connector is used to position the crushing cone radially. The second connector is installed in the mounting hole and connected to one end of the crushing cone. The second connector is used to position the crushing cone axially.

[0006] Furthermore, the positioning part includes a slot and a boss; The slot is opened at one end of the mounting hole, and the boss is connected to the crushing cone. The boss and the slot can be engaged to achieve the pre-positioning of the crushing cone and the mounting hole.

[0007] Furthermore, the first connecting member is an expansion coupling sleeve, and the first connecting member is located between the crushing cone and the mounting hole.

[0008] Furthermore, one end of the crushing cone is provided with an internal threaded hole, and the second connecting piece is threadedly engaged with the internal threaded hole to position the crushing cone axially.

[0009] Furthermore, the second connecting component is a bolt.

[0010] Furthermore, a flat washer and a spring washer are sequentially provided between one end of the crushing cone and the second connecting member.

[0011] Furthermore, the mounting holes include a first shaft hole and a second shaft hole; The diameter of the first shaft hole is smaller than that of the second shaft hole. The crushing cone is inserted into the first shaft hole. A groove is provided at the end of the first shaft hole away from the second shaft hole. The first connecting piece is located in the first shaft hole, and the second connecting piece is located in the second shaft hole.

[0012] Furthermore, the crushing cone includes a crushing cone body and a connecting shaft; One end of the crushing cone is connected to a connecting shaft. A boss is installed on the end of the connecting shaft near the crushing cone, and an internal threaded hole is opened on the end of the connecting shaft away from the crushing cone. The connecting shaft can be inserted into the first shaft hole and extends to the connection between the first shaft hole and the second shaft hole.

[0013] Furthermore, multiple grooves are evenly formed on the surface of the crushing cone, which are used for rapid discharge of crushed material.

[0014] Furthermore, the crushing cone fixing structure also includes a crushing cone ring, which is sleeved on the motor rotating shaft. Multiple mounting cylinders are evenly distributed around the outer wall of the crushing cone ring, and mounting holes are provided on the mounting cylinders.

Furthermore, the first and second connecting parts can be disassembled independently, eliminating the need to replace the entire mounting hole assembly and improving maintenance efficiency. This invention uses a positioning part to connect the crushing cone to the mounting hole for pre-positioning. Then, the first connecting part radially constrains the crushing cone to further prevent loosening. The second connecting part further locks and fixes the end of the crushing cone, providing axial constraint and achieving an even stronger anti-loosening effect.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," "third," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0021] The utility model concept of this application is described here: During practical use, the inventors discovered that the crushing cones on the working rolls of toothed roll crushers are mostly installed directly with bolts. This often leads to loosening and insecure installation during operation, prompting users to weld the crushing cones in place, which makes future replacements difficult. Furthermore, most crushing cones on the market only crush solid materials in a single pass, without the option to use additional auxiliary tools for further crushing, resulting in low crushing efficiency and excessive crushing time.

[0022] Based on this, the applicant provides a crushing cone fixing structure, which solves the problems of crushing cones easily becoming loose and not being securely installed during operation, making replacement convenient, and improving the crushing and refining of solid materials, enhancing the crushing effect and increasing crushing efficiency.

[0023] The following is in conjunction with the appendix Figures 1 to 5 The present application provides a detailed description of a crushing cone fixing structure through specific embodiments and application scenarios.

[0024] Reference Figure 1 A crushing cone fixing structure includes: a mounting hole 100, a positioning part 300, a first connecting member 400, and a second connecting member 500; Mounting hole 100 is used to install crushing cone 200; A positioning part 300 is formed between one end of the mounting hole 100 and the crushing cone 200. The positioning part 300 is used to position the installation of the crushing cone 200. Specifically, the initial installation position of the crushing cone 200 is pre-positioned by the positioning part 300, which takes into account both positioning accuracy and torque bearing capacity, ensuring safety and reliability.

[0025] The first connector 400 is located inside the mounting hole 100 and is sleeved on the crushing cone 200. The first connector 400 is used to position the crushing cone 200 radially. Specifically, the first connecting member 400 provides radial constraint to the crushing cone 200, further preventing the crushing cone 200 from loosening.

[0026] The second connector 500 is installed in the mounting hole 100 and connected to one end of the crushing cone 200. The second connector 500 is used to position the crushing cone 200 axially.

[0027] Specifically, the second connector 500 is connected to the end of the crushing cone 200 to form axial positioning, thereby achieving a further anti-loosening effect.

[0028] By forming a three-dimensional spatial positioning through radial and axial constraints, the overall displacement error of the crushing cone 200 can be controlled within 0.2mm, which is significantly better than the 0.5mm error level of the traditional single interference fit. Furthermore, the first connecting piece 400 and the second connecting piece 500 can be disassembled independently without the need to replace the entire mounting hole assembly, thus improving maintenance efficiency.

[0029] Among them, reference Figure 4 and Figure 5 In this embodiment, the crushing cone fixing structure also includes a crushing cone ring 10, which is sleeved on the motor rotating shaft. Multiple mounting cylinders 20 are evenly distributed on the outer wall of the crushing cone ring 10, and mounting holes 100 are provided on the mounting cylinders 20.

[0030] Specifically, the mounting cylinder 20 is welded or integrally formed onto the crushing cone ring 10; the number of mounting cylinders 20 is 4-12, and in this embodiment, the number of mounting cylinders 20 is 6; the mounting cylinder 20 is provided with a through mounting hole 100; the multiple mounting cylinders 20 evenly distributed around the circumference of the crushing cone ring 10 form an annular crushing area, improving crushing efficiency and processing capacity; the crushing cone ring 10 is sleeved on the motor rotating shaft, ensuring a unified power source and stable power transmission; during maintenance, the crushing cone 200 on a single mounting cylinder 20 can be disassembled without removing the entire crushing cone ring 10, enabling partial replacement and maintenance, reducing downtime and maintenance time and costs.

[0031] Reference Figures 2 to 5 In this embodiment, the positioning part 300 includes a slot 310 and a boss 320; The slot 310 is provided at one end of the mounting hole 100, and the boss 320 is connected to the crushing cone 200. The boss 320 and the slot 310 can be engaged to achieve the pre-positioning of the crushing cone 200 and the mounting hole 100.

[0032] Specifically, the slot 310 and the boss 320 are shaped to match each other. In this embodiment, the slot 310 and the boss 320 are cross-shaped, and the slot 310 and the boss 320 are tapered, which facilitates the self-locking of the crushing cone 200 and the mounting hole 100, taking into account both positioning accuracy and torque bearing capacity, ensuring safety and reliability, and preventing the crushing cone 200 from loosening. The slot 310 is opened on the mounting cylinder 20 at one end of the mounting hole 100. Through the snap-fit ​​engagement of the boss 320 and the slot 310, the time for manual calibration and alignment is saved, ensuring the initial assembly accuracy, avoiding the possibility that the crushing cone 200 may undergo radial offset or circumferential torsion due to the lack of a reference when installing the first connecting piece 400 and the second connecting piece 500. It also enhances the stability during the assembly process, reduces the risk of component damage, reduces equipment maintenance costs, and extends the service life of the overall structure.

[0033] Reference Figure 2 and Figure 4 In this embodiment, the mounting hole 100 includes a first shaft hole 110 and a second shaft hole 120; The diameter of the first shaft hole 110 is smaller than the diameter of the second shaft hole 120. The crushing cone 200 is inserted into the first shaft hole 110. A groove 310 is provided at the end of the first shaft hole 110 away from the second shaft hole 120. The first connector 400 is located in the first shaft hole 110 and the second connector 500 is located in the second shaft hole 120.

[0034] Specifically, the mounting hole 100 is stepped because the diameter of the first shaft hole 110 is smaller than that of the second shaft hole 120; and the first shaft hole 110 is also stepped. The first connector 400 is sleeved on the end of the crushing cone 200, and the first connector 400 contacts the step of the first shaft hole 110, which facilitates the positioning of the first connector 400 during installation. The second connector 500 contacts the step at the connection between the first shaft hole 110 and the second shaft hole 120, which facilitates the positioning of the second connector 500 during installation, improves the locking force of the second connector 500, ensures stable transmission of axial preload, and facilitates disassembly and replacement.

[0035] By setting the first shaft hole 110, a tight-fitting installation reference is provided for the crushing cone 200, while a radial expansion space is reserved for the first connecting member 400. This ensures the effective radial fixing function and effectively disperses radial stress, preventing the first shaft hole 110 from wearing or deforming due to excessive local stress. A groove 310 is provided at the end of the first shaft hole 110 away from the second shaft hole 120, which engages with the boss 320 of the crushing cone 200, further restricting the radial movement of the crushing cone 200 and ensuring positioning accuracy during crushing operations. The second shaft hole 120 prevents interference between the second connecting member 500 and the inner wall of the second shaft hole 120, while also providing space for the second connecting member 500 to expand. The tightening / untightening operation of the second connector 500 provides ample operating space for tools (such as wrenches), and ensures that the second connector 500 only bears axial preload without radial load, significantly extending its service life. The hierarchical structure of the first shaft hole 110 and the second shaft hole 120 naturally forms an assembly logic of installing radial components first and then axial components, which can avoid incorrect assembly sequence and improve assembly efficiency. Furthermore, since the first shaft hole 110 and the second shaft hole 120 are functionally separated, it is not necessary to touch the radial mating parts of the first connector 400 and the crushing cone 200 when disassembling the second connector 500, thus avoiding damage to the radial positioning structure during disassembly.

[0036] Reference Figures 1 to 3 In this embodiment, the first connector 400 is an expansion coupling sleeve, and the first connector 400 is located between the crushing cone 200 and the mounting hole 100.

[0037] Specifically, the expansion sleeve (also known as an expansion sleeve) is a mechanical part that uses axial force to cause radial elastic deformation of the inner and outer rings, thereby achieving a tight connection between the connected part and the base. Based on the pre-positioning of the positioning part 300, it rigidly connects the crushing cone 200 and the first shaft hole 110 through uniform radial pressure, forming a clearance-free fit and completely restricting the radial displacement and circumferential rotation of the crushing cone 200. The expansion sleeve achieves surface contact through overall radial expansion, which can evenly distribute the pressure on the mating surface of the crushing cone 200 and the first shaft hole 110, extending the service life of the crushing cone 200 by 20%-30%. Furthermore, the expansion sleeve uses bolts and other fasteners to provide axial force for tightening, eliminating the need for complex processes such as heating, cooling, or heavy-duty pressing, making installation and disassembly convenient and significantly improving efficiency. This improves maintenance efficiency. The pre-positioning of the positioning part 300 provides a precise installation reference for the expansion coupling sleeve, ensuring that the expansion coupling sleeve can be evenly fitted between the crushing cone 200 and the first shaft hole 110, avoiding uneven force on the expansion sleeve due to initial position offset. The rigid fixation of the expansion coupling sleeve can further lock the fit of the positioning part, preventing the slot 310 and the boss 320 from loosening or wearing under vibration conditions. This synergistic design of pre-positioning + precision fixing enables the crushing cone 200 to maintain stable positional accuracy under high-speed rotation and severe vibration conditions, significantly improving the operational reliability of the equipment.

[0038] Reference Figure 2 and Figure 3 In this embodiment, one end of the crushing cone 200 is provided with an internal threaded hole 510, and the second connecting member 500 is threadedly engaged with the internal threaded hole 510 to position the crushing cone 200 axially.

[0039] Specifically, during crushing operations, the crushing cone 200 is subjected not only to radial impact loads but also to axial movement due to material compression and equipment vibration. The second connecting piece 500 engages with the internal threaded hole 510, directly restricting the axial movement of the crushing cone 200 through the self-locking characteristic and pre-tightening force of the thread. Simultaneously, it forms a three-dimensional constraint with the radial positioning of the expansion sleeve, ensuring the stability of the crushing cone 200's position in three-dimensional space. The second connecting piece 500 is easy to install and operate, reducing maintenance costs. During tightening, the axial position of the crushing cone 200 can be finely adjusted by controlling the thread insertion depth, with an accuracy of 0.1-0.2mm. This fine-tuning capability can compensate for pre-positioning issues. The expansion sleeve addresses potential axial errors in the assembly, ensuring the working end face of the crushing cone 200 is in the optimal working position, thereby guaranteeing stable crushing gaps and improving the uniformity of crushed product particle size. The expansion sleeve achieves a rigid connection between the crushing cone 200 and the first shaft hole 110 through radial surface contact, while the threaded second connector 500 pulls the crushing cone 200 axially, forming a gapless, all-around rigid whole between the crushing cone 200, the expansion sleeve, and the mounting hole 100. This not only fully constrains the displacement freedom of the crushing cone 200 and improves the operational stability of the equipment under impact and vibration conditions, but also reduces processing and maintenance costs, demonstrating significant technical practicality and industrial application value.

[0040] Reference Figure 2 , Figure 3 and Figure 5 In this embodiment, the crushing cone 200 includes a crushing cone body 210 and a connecting shaft 220; One end of the crushing cone 210 is connected to a connecting shaft 220. A boss 320 is installed on the end of the connecting shaft 220 near the crushing cone 210. An internal threaded hole 510 is opened on the end of the connecting shaft 220 away from the crushing cone 210. The connecting shaft 220 can be inserted into the first shaft hole 110 and extends to the connection between the first shaft hole 110 and the second shaft hole 120.

[0041] Specifically, the crushing cone 210 and the connecting shaft 220 are integrally formed; the diameter of the end of the connecting shaft 220 away from the crushing cone 210 is smaller than the diameter of the rest of the connecting shaft 220, which facilitates the installation of the expansion coupling sleeve; the diameter of the connecting shaft 220 is slightly smaller than the first shaft hole 110, which facilitates the installation of the connecting shaft 220 into the first shaft hole 110.

[0042] The crushing cone 210 is in direct contact with solid materials and bears crushing loads such as compression and impact. It is the core actuator for realizing the crushing function of the equipment. The connecting shaft 220 realizes the radial positioning of the crushing cone 200 in the first shaft hole 110. At the same time, it provides axial space for the subsequent assembly of the second connecting piece 500, ensuring that the second connecting piece 500 can cooperate with the internal thread hole 510 of the connecting shaft 220 in the second shaft hole 120 to form a complete axial fixing chain. Furthermore, the connecting shaft 220 evenly transmits the crushing load borne by the crushing cone 210 during operation to the mounting cylinder 20, avoiding load concentration that could lead to local structural damage.

[0043] Reference Figures 1 to 3 In this embodiment, the second connector 500 is a bolt.

[0044] Specifically, the second connector 500 is a wing bolt, countersunk bolt, or socket head cap bolt. When the second connector 500 is a wing bolt with a handle, it can be operated without tools, achieving quick disassembly. Through the cooperation between the bolt and the internal threaded hole 510, it completely resists the axial movement, impact load, and vibration interference generated during crushing operations. The stable preload can eliminate the axial clearance between the connecting shaft 220 and the expansion sleeve and mounting hole 100, further improving the overall positioning accuracy. The assembly and maintenance efficiency is excellent, making it suitable for industrial mass production and on-site maintenance. Moreover, the radial rigidity constraint of the expansion sleeve can prevent the connecting shaft 220 from deflecting when subjected to axial force, avoiding local wear of the thread profile due to unilateral force on the bolt, and extending the service life of the bolt.

[0045] Reference Figure 2 and Figure 3 In this embodiment, a flat washer 520 and a spring washer 530 are sequentially provided between one end of the crushing cone 200 and the second connecting member 500.

[0046] Specifically, the flat washer 520 makes step contact with the connection between the first shaft hole 110 and the second shaft hole 120. A spring washer 530 is placed at the end of the flat washer 520 away from the connecting shaft 220. The flat washer 520 and the spring washer 530 are sleeved on the outside of the bolt stud. By setting the flat washer 520, the inherent defects of direct contact between the bolt and the connecting shaft 220 are solved. When the bolt head is in direct contact with the end face of the connecting shaft 220, the axial pressure during bolt tightening will be concentrated locally due to the small contact area, which can easily lead to indentation, deformation or even damage to the end face of the connecting shaft 220. The flat washer 520 increases the contact area and disperses the concentrated pressure to a larger area, avoiding damage to the end face of the connecting shaft 220 due to excessive local stress, extending the service life of the crushing cone 200. In addition, the flat washer 520 can fill the small end face gap, so that the preload of the bolt is evenly transmitted to the connecting shaft 220. 20. To ensure the reliability of axial positioning, a spring washer 530 is used to provide continuous anti-loosening preload to resist vibration and loosening. When crushing materials, the crushing cone 210 will generate strong vibration and impact. This vibration can easily cause gaps in the threaded fit between the bolt and the internal threaded hole 510, leading to loosening. After the bolt is tightened, the spring washer 530 will undergo elastic deformation, generating continuous radial elastic force, so that the bolt thread and the thread surface of the internal threaded hole 510 are always tightly fitted, eliminating the gaps caused by vibration and effectively preventing the bolt from loosening. In addition, during long-term operation, the thread surfaces of the bolt and the internal threaded hole 510 may experience slight wear due to friction, or slight deformation due to temperature changes and load fluctuations, resulting in an increase in the fit clearance. The elastic deformation capacity of the spring washer 530 can automatically compensate for these gaps, maintain the tightness of the threaded fit, and ensure that the axial positioning does not fail.

[0047] The flat washer 520 and the spring washer 530 can freely exert pressure dispersion and anti-loosening functions within the second shaft hole 120 without being restricted by the shaft hole space, ensuring stable transmission of axial preload. Both the flat washer 520 and the spring washer 530 are standardized and universal parts, with low procurement costs and convenient installation. They can also be replaced individually after wear, without the need to replace the bolts or the crushing cone 200, which greatly reduces the equipment maintenance costs and downtime.

[0048] Reference Figure 3 and Figure 5 In this embodiment, the surface of the crushing cone 210 is uniformly provided with multiple grooves 600, which are used for rapid discharge after crushing.

[0049] Specifically, by uniformly opening multiple grooves 600 on the surface of the crushing cone 210, the crushing cone 210 is shaped like a plum blossom petal, which further improves the crushing and refining of solid materials by the crushing cone 210, and facilitates the rapid discharge of crushed materials from the grooves 600, thereby enhancing the crushing effect and improving the crushing efficiency.

[0050] When the crushed material is quickly discharged through the groove 600, the crushing chamber will not be hindered by the entry of new material due to the incomplete discharge of old material, ensuring that the equipment can continuously receive material to be crushed, significantly increasing the material processing capacity per unit time. Moreover, the rapid discharge of the groove 600 can reduce over-crushing, making the crushing process more in line with the target particle size requirements, reducing ineffective energy consumption. At the same time, it reduces the continuous friction between the retained material and the surface of the crushing cone 210, which can reduce the wear rate of the surface of the crushing cone 210, extend its service life, ensure that the particle size of the discharged material is more uniform, and improve the quality stability of the crushed product. Furthermore, the rapid discharge function of the groove 600 reduces material retention from the source, reduces the probability of blockage and hardening, reduces the number of manual cleanings, reduces maintenance costs, and improves the stability and continuity of equipment operation.

[0051] Working principle: In use, the connecting shaft 220 is inserted into the first shaft hole 110, and the pre-positioning of the crushing cone 210 and the mounting hole 100 is achieved through the boss 320 and the slot 310. Then, the expansion coupling sleeve is inserted from the second shaft hole 120 until the expansion coupling sleeve contacts the step of the first shaft hole 110. The expansion coupling sleeve is tightened by providing axial force through fasteners such as bolts, which radially constrains the crushing cone 200 and further prevents loosening. Then, the flat washer 520 and the spring washer 530 are installed so that the flat washer 520 contacts the step at the connection between the first shaft hole 110 and the second shaft hole 120. The crushing cone 200 is axially constrained by the threaded engagement of the bolt and the internal threaded hole 510, achieving a further anti-loosening effect.
