[0002] In many fields such as mining, construction, and road building, crushers are indispensable key equipment used to break large pieces of stone into smaller particles that meet specific needs, laying the foundation for subsequent processing and use. Traditional stone crushers have some significant drawbacks that restrict their efficiency and ease of use. From a structural design perspective, traditional crushers are mostly single-machine crushers or integral jaw crushers with secondary crushing, making disassembly and replacement extremely inconvenient when the jaw plates or hammers are damaged. Integral designs have significant limitations, wasting considerable manpower, resources, and time, and causing the crusher to malfunction during replacement, affecting overall production progress. Furthermore, when other core components inside the crusher, such as the crushing shaft and blades, are damaged, the structural design hinders disassembly. Maintenance personnel often need to spend a lot of time and effort removing numerous unrelated parts to access the component requiring repair or replacement, making the maintenance process cumbersome and complex, greatly reducing the equipment's efficiency.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0035] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0036] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0037] In existing technologies, secondary crushers are generally designed as a single unit. Material is first crushed in the primary crushing hopper, then falls into the secondary crushing hopper for further crushing, achieving gradient crushing, reducing the difficulty of material crushing, and improving crushing efficiency. However, single-unit secondary crushers are large, heavy, and occupy a lot of space, making them inconvenient to transport and move. Furthermore, disassembly and maintenance of internal working parts are inconvenient.

[0038] In view of this, the designers have provided a detachable crushing device that is easy to transport and move, as well as easy to maintain and replace parts.

[0039] Please refer to Figures 1-6 This embodiment provides a detachable crushing device, including:

[0040] The system includes a transfer mechanism 100, a crushing mechanism 200, and a connecting mechanism 300. The transfer mechanism 100 is provided with a discharge port 112, and the crushing mechanism 200 is provided with a receiving port 211 and a discharge port 212. The crushing mechanism 200 is detachably connected to the transfer mechanism 100 through the connecting mechanism 300, and the discharge port 112 is connected to the receiving port 211.

[0041] As described above, the working principle of the detachable crushing device provided in this embodiment is as follows:

[0042] The transfer mechanism can be a frame structure or a jaw crusher, and can be flexibly configured according to the application scenario. For example, when secondary crushing is required, the transfer mechanism can be set as a jaw crusher, connected to the folding arm of an excavator, and then the crushing mechanism can be connected to the jaw crusher. At this time, the discharge port of the jaw crusher is connected to the receiving port of the crushing mechanism. In use, the material to be crushed is put into the primary transfer mechanism 100, which performs primary crushing. The crushed material that meets the particle size requirement is discharged from the discharge port 112 and enters the secondary crushing mechanism 200 from the receiving port 211. The crushing mechanism 200 continues to crush the material, reducing the particle size, and finally, the material that meets the particle size requirement is discharged from the discharge port 212.

[0043] Because the material is crushed in a graded, staged manner, the difficulty of crushing the material is reduced, and the crushing efficiency is improved. Meanwhile, the transfer mechanism 100 and the crushing mechanism 200 are detachably connected via the connecting mechanism 300. When movement and transportation are required, the crushing mechanism 200 and the transfer mechanism 100 can be disassembled and separated, allowing for independent transportation. They are small in size, lightweight, and more flexible in movement and transportation, enabling flexible and professional operation even in harsh environments. Furthermore, after separation, they are independent of each other and can be maintained independently without obstruction or interference. Disassembly and assembly are convenient, and maintenance costs are low.

[0044] Furthermore, in some scenarios, the crushing mechanism can be detached from the transfer mechanism, allowing the jaw crusher to be used independently; alternatively, the transfer mechanism can be configured as a frame structure, with the crushing mechanism directly mounted on it for independent material processing. This versatility and wide applicability make it suitable for various applications. By mounting the transfer mechanism on the excavator's folding boom, mobile crushing operations can be achieved. For example, the original bucket mounting position on the excavator can be removed, and the transfer mechanism can be installed in the original bucket location. Specific installation structures can be referenced from existing known technologies.

[0045] The following embodiments illustrate the details of the detachable crushing device of this application by way of example.

[0046] Please refer to Figures 1-2 In this embodiment, optionally, the detachable crushing device includes a transfer mechanism 100, a crushing mechanism 200, and a connecting mechanism 300. The transfer mechanism 100 is detachably connected to the crushing mechanism 200 via the connecting mechanism 300. Material enters through the transfer mechanism 100, is initially crushed by the transfer mechanism 100, and the crushed material falls into the crushing mechanism 200, where it is further crushed.

[0047] It should be understood that detachable crushing devices can crush construction slag or ore, and have a variety of applications. This embodiment does not impose any specific limitations on them.

[0048] Please refer to Figures 1-4Optionally, the transfer mechanism 100 is configured as a jaw crusher, comprising a first housing 110, a first flange connecting plate 120, a power unit 130, a transmission unit 140, a moving jaw plate 150, a fixed jaw plate 160, and a linkage unit 170. The first housing 110 has an inlet 111 and an outlet 112, which are connected. The first flange connecting plate 120 is fixed to the bottom of the first housing 110 and surrounds the outlet 112. The power unit 130 and the transmission unit 140 are both mounted on the first housing 110, and the power unit 130 is connected to the moving jaw plate 150 via the transmission unit 140. The moving jaw plate 150 and the fixed jaw plate 160 are both installed inside the first housing 110, forming a crushing space between them. The inlet 111 connects to the upper part of the crushing space, and the outlet 112 connects to the lower part of the crushing space. The linkage unit 170 can transmit the power of the power unit 130 to the crushing mechanism 200.

[0049] During operation, the power unit 130 starts, driving the movable jaw plate 150 to move relative to the fixed jaw plate 160 via the transmission unit 140. The movable jaw plate 150 and the fixed jaw plate 160 work together to crush the material between them. Obviously, this embodiment does not improve the crushing structure or crushing distance of the transfer mechanism 100. The principle of how the movable jaw plate 150 moves under the drive of the power unit 130 and the transmission unit 140, and how the movable jaw plate 150 and the fixed jaw plate 160 cooperate to crush the material, can be directly referred to existing known structures. To avoid repetition and redundancy, this embodiment will not provide a detailed description.

[0050] In some embodiments, optionally, the power unit 130 includes a hydraulic motor 131, a power shaft 132, and a first flywheel 133. The transmission unit 140 includes a first transmission wheel 141, a transmission belt 142, a second transmission wheel 143, and a pull rod 144. The hydraulic motor 131 is fixed inside the first housing 110. The first transmission wheel 141 is fixed to the output shaft of the hydraulic motor 131. The first transmission wheel 141 is connected to the second transmission wheel 143 via the transmission belt 142. The second transmission wheel 143 is mounted on the power shaft 132, which is rotatably mounted on the first housing 110. The power shaft 132 can be a crankshaft. One end of the movable jaw plate 150 can be sleeved on the crankshaft, and the other end can be connected to the first housing 110 via the pull rod 144. The pull rod 144 is fixedly connected to the first housing 110, and the other end of the pull rod 144 is rotatably connected to the back of the movable jaw plate 150. The first flywheel 133 is mounted on the power shaft 132, and the first flywheel 133 and the first transmission wheel 141 are located on opposite sides of the first housing 110.

[0051] During operation, the hydraulic motor 131 starts, transmitting power to the second transmission wheel 143 via the first transmission wheel 141 and the transmission belt 142. The second transmission wheel 143 drives the power shaft 132 to rotate, thereby causing the moving jaw plate 150 to move relative to the fixed jaw plate 160. During this process, the first flywheel 133 rotates together with the power shaft 132.

[0052] Optionally, the linkage unit 170 can be configured as a linkage belt.

[0053] Please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 In this embodiment, optionally, the crushing mechanism 200 includes a second housing 210, a second flange connecting plate 220, a baffle plate 230, a crushing execution unit 240, and a screen 250. The second housing 210 is provided with a receiving port 211 and a discharging port 212 arranged opposite to each other. The second flange connecting plate 220 is fixed to the top of the second housing 210. The baffle plate 230 is installed inside the second housing 210, with the baffle plate 230 near the receiving port 211. The baffle plate 230 blocks a portion of the receiving port 211, thereby reducing the width of the receiving port 211. A material discharge channel is formed between the baffle plate 230 and the second housing 210. The crushing execution unit 240 is connected to the second housing 210, and the linkage unit 170 is in transmission cooperation with the crushing execution unit 240, thereby transmitting the power of the power unit 130 to the crushing mechanism 200. Screen 250 is installed at discharge port 212. After the material is crushed, the material that meets the particle size requirements can be discharged through screen 250.

[0054] Since the crushing mechanism 200 and the transfer mechanism 100 share the same power unit 130, energy can be saved.

[0055] It should be understood that when the crushing execution unit 240 is working, some material may move towards the receiving port 211 under the impact. If the material is discharged from the receiving port 211, it will hit the transfer mechanism 100, which may damage the transfer mechanism 100. Since the baffle plate 230 is set at the receiving port 211, it can block the material discharged from the receiving port 211 and reduce the probability of the material rushing out of the receiving port 211. This will not affect the normal material discharge of the transfer mechanism 100, and can also improve the safety of the device operation.

[0056] Optionally, the baffle plate 230 is provided with a guiding ramp 231, which faces the receiving port 211. The guiding ramp 231 has a first side close to the discharge channel and a second side away from the discharge channel. The height of the second side is higher than that of the first side, so that the guiding ramp 231 can guide the material to slide into the discharge channel. The material falling from the discharge port 212 or the material rushing out from the receiving port 211 can fall onto the guiding ramp 231 under the action of gravity, and be guided by the guiding ramp 231 to the discharge channel, thereby entering the second housing 210.

[0057] In some embodiments, the baffle plate 230 can be rotatably connected to the second housing 210, thereby adjusting the inclination angle of the material ramp, providing flexibility and preventing material from accumulating on the guide ramp 231. Obviously, in other embodiments, the baffle plate 230 can be directly fixed inside the second housing 210, with the angle of the baffle plate 230 fixed, sufficient to achieve the effects of blocking and guiding material.

[0058] Optionally, the crushing execution unit 240 includes an execution shaft 241, a crushing cutter 242, and a second flywheel 243. The execution shaft 241 is rotatably mounted inside the second housing 210. The crushing cutter 242 and the second flywheel 243 are both mounted on the execution shaft 241, with the crushing cutter 242 located inside the second housing 210 and the second flywheel 243 located outside the second housing 210. A linkage belt is simultaneously tensioned outside both the first flywheel 133 and the second flywheel 243. The power unit 130 transmits power to the first flywheel 133, which drives the second flywheel 243 to rotate via the linkage belt, thereby driving the execution shaft 241 to rotate, and ultimately driving the crushing cutter 242 to rotate, using the crushing cutter 242 to crush the material falling from the receiving port 211.

[0059] It should be understood that the crushing cutter 242 can be a hammer or a blade, etc. The appropriate cutter can be selected as needed to crush different types of materials and improve crushing efficiency. That is, the crushing mechanism can be a hammer crusher or a blade crusher, etc.

[0060] In addition, the screen 250 can be detachably connected to the second housing 210, which makes it easy to adjust the screen 250 with different apertures according to the material particle size requirements, making it flexible in use.

[0061] In this embodiment, optionally, the connecting mechanism 300 can be configured as a bolt assembly. The bolt assembly is fixedly connected to both the first flange connecting plate 120 and the second flange connecting plate 220, thereby achieving a detachable connection between the transfer mechanism 100 and the crushing mechanism 200. The connection method is simple, reliable, and easy to assemble and disassemble.

[0062] The detachable crushing device provided in this embodiment, by designing the transfer mechanism 100 and the crushing mechanism 200 to be detachably connected, allows maintenance personnel to complete the replacement work in a short time when a component is damaged, greatly improving the ease of use and work efficiency of the equipment. At the same time, through reasonable structural design and parameter optimization, the crushing mechanism 200 can better adapt to the crushing requirements of different materials, further improving crushing efficiency and reducing production costs, thus possessing broad application prospects and market value.

[0063] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
