Description

Technical Field

[0001] This application relates to the field of crusher technology, and more particularly to a crushing device. Background Technology

[0002] Open-pit coal mining machines often encounter large chunks of raw coal during mining operations. These large chunks can easily cause blockages or damage to transport equipment during subsequent transportation.

[0003] The main solution in the existing technology is to set up crushing equipment to crush large pieces of raw coal. The crushed coal pieces can reduce the occurrence of blockages in transportation equipment.

[0004] However, during operation, the crusher is prone to squeezing the coal blocks located below it, which increases the friction between the transport equipment and other related components, thereby accelerating the wear of the transport equipment and other components. Utility Model Content

[0005] This application provides a crushing device to solve the problem that the crushed material is prone to wear and tear on transportation equipment.

[0006] The present application provides a crushing device, including a first housing, the first housing including at least two crushing components arranged side by side and at least one first plate, the first plate being disposed in the first housing and located between two adjacent crushing components.

[0007] The crushing assembly may include a crushing disc and crushing teeth. The crushing disc is rotatably disposed in a first housing, and the crushing teeth are arranged around the periphery of the crushing disc. The crushing teeth are used to crush the material fed into the first housing.

[0008] With this configuration, the first plate can separate the various crushing components inside the first box, forming multiple crushing working zones. The material to be crushed is crushed through the gap between the crushing components and the first plate, and the operator can pour the material to be crushed into each crushing working zone separately, avoiding the situation where the material piles up in one crushing working zone and causes blockage.

[0009] As an optional implementation, the crushing assembly provided in this application embodiment may further include a rotating component and at least two fixed seats. The fixed seats are connected to the outer wall of the first housing. A crushing disc is sleeved around the rotating component, and both ends of the rotating component pass through the wall of the first housing and are connected to the fixed seats.

[0010] With this configuration, both the front and rear ends of the rotating component are connected to the fixed base, which is then fixedly connected to the side surface of the first housing. This method of fixing the rotating component can reduce the vibration generated when the rotating component rotates rapidly.

[0011] As an optional implementation, the end of the breaking tooth provided in this application embodiment abuts against the surface of the first plate.

[0012] With this configuration, the crushing teeth are arranged in sequence around the periphery of the crushing disc. The crushing teeth can be further subdivided into a cutting tooth part and a base part. The cutting tooth part contacts the side of the first plate. During operation, the material is crushed by the cutting teeth and the first plate, forming fine particles that fall onto the conveying equipment below.

[0013] As an alternative implementation, the crushing assembly may also include a power unit mounted on one of the mounting bases.

[0014] As an optional implementation, the mounting base may include an upper base and a lower base, which are joined together.

[0015] As an optional implementation, both the upper and lower seats have arc-shaped grooves on their sides, and the holes formed by the splicing of the arc-shaped grooves cooperate with the rotating parts.

[0016] This design allows for easy disassembly of the lower seat, facilitating the replacement of the crushing teeth around the crushing disc, reducing maintenance costs of the crushing device, and extending its service life.

[0017] As an optional implementation, the first housing may further include a first connecting plate, which is disposed at one end of the first housing, and the first housing is connected to a feed hopper through the first connecting plate.

[0018] As an alternative implementation, the feed hopper has openings at both the top and bottom, with the top opening being larger than the bottom opening.

[0019] As an alternative implementation, the first housing may further include a second connecting plate, which is disposed at the end away from the first connecting plate, and the first housing is connected to the auxiliary transport equipment through the second connecting plate.

[0020] As an optional implementation, the surface of the second connecting plate is provided with multiple through holes at intervals for bolt connection with auxiliary transportation equipment.

[0021] With this configuration, the material is crushed into small particles by the crushing teeth and the first plate. Because the material size is reduced, the crushing teeth are prevented from directly squeezing the conveying equipment below the first box, thus reducing direct wear on the bottom conveying system.

[0022] This embodiment of the application achieves material compression and grinding into fine particles by setting a crushing component and a first plate, avoiding the situation where the crushing component and the conveying equipment below are squeezed together with large particles, causing wear on the conveying equipment. In addition, by setting multiple crushing discs with the same spacing, it can ensure that the crushed particles are of uniform size; by using a technical solution of detachable crushing teeth and uniformly distributed crushing teeth, the crushing component is subjected to stable force during operation, which helps to extend the service life of the equipment and facilitates maintenance.

[0023] In addition to the technical problems solved by the embodiments of this application, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions described above, other technical problems that the crushing device provided by this application can solve, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further explained in detail in the specific embodiments.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments.

[0037] Open-pit coal mining machines often encounter large chunks of raw coal during mining operations. These large chunks can easily cause blockages or damage to transport equipment during subsequent transportation.

[0038] The main solution in the existing technology is to set up crushing equipment to crush large pieces of raw coal. The crushed coal pieces can reduce the occurrence of blockages in transportation equipment.

[0039] However, during operation, the crusher is prone to squeezing the coal blocks located below it, which increases the friction between the transport equipment and other related components, thereby accelerating the wear of the transport equipment and other components.

[0040] To address the aforementioned issues, this application embodiment improves the crushing component 200 of the crushing device. When the crushing device provided in this application is in operation, the material is conveyed from the scraper conveyor into the receiving hopper 400 and then falls to the crushing component 200. The crushing component 200 rotates under power drive. Larger coal blocks are deformed and crushed into smaller particles that can pass through the gap between the toothed discs by the compression between the crushing teeth 202 and the first plate 300, reducing the wear of subsequent transportation equipment. The smaller particles also facilitate subsequent transportation.

[0041] Figure 1 This is a schematic diagram of the structure of a crushing device provided in an embodiment of this application; Figure 2 for Figure 1 Rear view;

[0042] like Figure 1 and Figure 2 As shown in the embodiment of this application, a crushing device may include a first housing 100. The first housing 100 includes at least two crushing components 200 arranged side by side and at least one first plate 300. The first plate 300 is disposed inside the first housing 100 and is located between two adjacent crushing components 200.

[0043] The first plate 300 can separate the various crushing components 200 set in the first box 100, forming multiple crushing working zones. The material to be crushed is crushed through the gap between the crushing component 200 and the first plate 300.

[0044] Furthermore, operators can pour the materials to be crushed into each crushing working zone separately, avoiding the situation where materials pile up in one crushing working zone and cause blockages.

[0045] The specific structure of the crushing component 200 will be described in detail below.

[0046] Figure 3 This is a schematic diagram of the structure of a crushing component in a crushing device provided in an embodiment of this application.

[0047] Reference Figures 1 to 3 As shown, in one optional implementation, the crushing assembly 200 may include a crushing disc 201 and crushing teeth 202. The crushing disc 201 is rotatably disposed inside the first housing 100, and the crushing teeth 202 are arranged around the periphery of the crushing disc 201. The crushing teeth 202 are used to crush the material fed into the first housing 100.

[0048] It is understandable that the crushing teeth 202 are arranged sequentially and spaced around the periphery of the crushing disc 201. The crushing teeth 202 can be further subdivided into a cutting tooth part and a base part. The cutting tooth part contacts the side of the first plate 300. During operation, the material is crushed by the cutting teeth and the first plate 300 and forms fine particles that fall into the conveying equipment below.

[0049] It is worth mentioning that the number of crushing discs 201 provided in this embodiment is three. The specific number of crushing discs 201 can be changed according to the actual situation, and this application does not impose a limit on the number. The relative rotation angle between each crushing disc 201 is 360 / 3n degrees. The crushing teeth 202 are evenly distributed, and the spacing between the crushing discs 201 is also the same. This helps to ensure that the particle size of the crushed material is uniform, and also avoids excessive local wear of the crushing teeth 202. In addition, the crushing teeth 202 are detachable, allowing for the replacement or repair of individual worn crushing teeth 202, reducing the overall maintenance cost of the device.

[0050] Reference Figure 1 and Figure 2 As shown, the crushing assembly 200 provided in this application embodiment may further include a rotating component 203 and at least two fixed seats 204. The fixed seats 204 are connected to the outer wall of the first housing 100. The rotating component 203 is fitted with a crushing disc 201 around its periphery. Both ends of the rotating component 203 pass through the wall of the first housing 100 and are connected to the fixed seats 204.

[0051] The end of the breaking tooth 202 provided in this embodiment abuts against the surface of the first plate 300.

[0052] It is understood that the fixed base 204 is an assembly structure with a hole in the center for the assembly of the rotating component 203. The crushing device provided in this application embodiment contains four fixed bases 204 and two rotating components 203. The front and rear ends of the rotating component 203 are connected to the fixed base 204, and the fixed base 204 is then fixedly connected to the side surface of the first housing 100. Fixing the rotating component 203 in this way can reduce the shaking generated when the rotating component 203 rotates rapidly.

[0053] It should be noted that the crushing disc 201 provided in this application embodiment is connected to the rotating part 203 by welding.

[0054] Reference Figure 2 As shown, as an optional implementation, the crushing assembly 200 may also include a power unit 205, which is mounted on one of the mounting bases 204.

[0055] It is understood that the crushing device provided in this application embodiment includes two power units 205, that is, each rotating component 203 requires and only requires one power unit 205 to drive it. The power unit 205 consists of a hydraulic motor and a reducer, and the power unit 205 is mounted on a fixed base 204 at one end of the rotating component 203 and connected to the rotating component 203.

[0056] Reference Figure 1 As shown, as an optional implementation, the fixing base 204 may include an upper base 2041 and a lower base 2042, which are joined together.

[0057] Both the upper seat 2041 and the lower seat 2042 have arc-shaped grooves on their sides, and the holes formed by the splicing of the arc-shaped grooves cooperate with the rotating part 203.

[0058] The upper seat 2041 and lower seat 2042 provided in this application embodiment are both provided with arc-shaped grooves on their sides, and the holes formed by the splicing of the arc-shaped grooves cooperate with the rotating component 203. It can be understood that, specifically when installing the rotating component 203 provided in this application embodiment, the lower seat 2042 is first fixedly connected to the surface of the first housing 100 by bolts, then the rotating component 203 is placed on the circular groove of the lower seat 2042, and finally the upper seat 2041 is covered and the upper seat 2041 and lower seat 2042 are fixedly connected by bolts.

[0059] Understandably, fixing the rotating part 203 with a fixed base 204 makes it easier for operators to replace it and reduces the maintenance cost of the equipment.

[0060] Reference Figure 1 and Figure 4 As shown, as an optional implementation, the first housing 100 may further include a first connecting plate 101, which is disposed at one end of the first housing 100, and the first housing 100 is connected to a feed hopper 400 through the first connecting plate 101.

[0061] The feed hopper 400 provided in this embodiment has openings at both the top and bottom, with the top opening being larger than the bottom opening.

[0062] It is understandable that the first connecting plate 101 of the first box 100 is connected to the feed hopper 400 by bolts. The material to be processed is poured into the feed hopper 400 and then falls into the crushing component 200 for crushing. Feeding the material by pouring it into the feed hopper 400 can prevent the crushed material from flying out during feeding and also makes it easier for the operator to feed the material.

[0063] Reference Figure 1 and Figure 4 As shown, as an optional implementation, the first housing 100 may further include a second connecting plate 102, which is disposed at the end away from the first connecting plate 101, and the first housing 100 is connected to the auxiliary transport equipment through the second connecting plate 102.

[0064] The second connecting plate 102 provided in this application embodiment has multiple through holes spaced apart on its surface for bolt connection with auxiliary transportation equipment.

[0065] It is understandable that the transport equipment is bolted to the lower end of the first box 100 via the second connecting plate 102. After the material is crushed, it falls onto the auxiliary transport equipment. The material is crushed into small particles by the crushing teeth 202 and the first plate 300. Since the material size is reduced, the crushing teeth 202 are prevented from directly squeezing the transport equipment below the first box 100, thus reducing the direct wear on the bottom conveying system.

[0066] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the application disclosed herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this application are indicated by the following claims.

[0067] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope.
