Description

Technical Field

[0001] This invention relates to the field of belt conveyor technology, and in particular to a belt conveyor tail cleaning structure. Background Technology

[0002] In cement production, when belt conveyors transport clinker, wet ash, and cement powder, the materials tend to adhere to the surface of the belt. Therefore, multiple cleaning mechanisms are installed at the tail of the conveyor to effectively clean the belt.

[0003] Existing technologies include integrated scraper cleaning mechanisms, but these require complete replacement after localized wear and have poor compatibility with belts, exhibiting significant drawbacks. Other designs feature segmented, multi-scraper parallel designs with elastic floating space for the scrapers. These multi-scraper designs are generally modular, using an arc-shaped plate as the main body fitted onto the main shaft, with the scrapers, scraper supports, and springs fitted and installed onto the arc-shaped plate. When replacing the scrapers, the supports and springs must also be disassembled and replaced, resulting in wasted structural components and increased costs.

[0004] Meanwhile, when the arc-shaped plate is spliced ​​and installed onto the main shaft, through holes are usually opened at both ends of the arc-shaped plate. After the arc-shaped plate is fitted onto the main shaft, bolts are inserted into the through holes to complete the overall positioning of the arc-shaped plate and the scraper. This installation method is relatively troublesome and requires a lot of tools such as bolts and screwdrivers. Moreover, after installation, the arc-shaped plate and the scraper may still move along the axial direction of the main shaft, affecting the cleaning effect of the cleaning mechanism on the belt. Furthermore, it does not meet the equipment's requirements for quick disassembly and maintenance, and has certain limitations in use.

[0005] Therefore, it is necessary to provide a belt conveyor tail cleaning structure to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a belt conveyor tail cleaning structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a belt conveyor tail cleaning structure, comprising a plurality of scrapers and two main shafts fixed on the belt conveyor, wherein a plurality of support rods are sequentially arranged axially between the two main shafts, a support assembly for supporting the scrapers is sleeved on the outer surface of the support rods, and a limiting assembly for positioning the support assembly is provided on the support rods, and a telescopic assembly is provided between adjacent support rods.

[0008] The telescopic component has an extended state and a retracted state. In the extended state, it engages with adjacent support rods to achieve relative fixation of the two adjacent support rods. In the retracted state, it forms a space through which the support component can pass.

[0009] The limiting component works in conjunction with the support component to position the support component along the circumferential and axial directions of the support rod, and the limiting component allows the support component and the scraper to float elastically along the radial direction of the support rod.

[0010] As a further aspect of the present invention: the limiting component includes a connecting rod slidably mounted on the support rod, and a second spring is fixedly installed between the connecting rod and the inner wall of the support rod; the portion of the connecting rod protruding from the support rod is positioned in conjunction with the support component, and the second spring provides elastic floating for the support component through the connecting rod.

[0011] As a further embodiment of the present invention: the support assembly includes an incomplete ring sleeved on the outside of the support rod and movably engaged with the connecting rod. Two brackets are fixedly installed on the outer surface of the incomplete ring, and two sliding plates are slidably installed inside the brackets. The ends of the two sliding plates are jointly fixedly installed with a scraper retainer for fixing the scraper.

[0012] As a further aspect of the present invention: the incomplete ring has a first notch and a second notch connected in the circumferential direction of the support rod, the length of the first notch in the circumferential direction of the support rod is not less than the length of the connecting rod in the circumferential direction of the support rod, and the length of the second notch in the axial direction of the support rod is equal to the length of the connecting rod in the axial direction of the support rod.

[0013] As a further embodiment of the present invention: the slide plate is slidably mounted on the bracket along the radial direction of the support rod, and the slide plate and the connecting rod are relatively fixed by bolts. The second spring enables the scraper to float elastically through the connecting rod, the slide plate and the retainer.

[0014] As a further aspect of the present invention: the telescopic assembly includes a sleeve rod and a partition plate fixedly connected to the sleeve rod. The sleeve rod is slidably installed in one of two adjacent support rods along the axial direction, and a first spring is fixedly installed between the sleeve rod and the support rod. A plurality of buckles are fixedly installed at the end of the partition plate away from the first spring. The end surface of the support rod corresponding to the buckle is provided with a groove adapted to the buckle. The first spring causes the buckle to be inserted into the groove to form a lock.

[0015] As a further aspect of the present invention: when the buckle separates from the slot, a space is formed, and the length of this space along the axial direction of the support rod is not less than the length of the incomplete ring along the axial direction of the support rod.

[0016] As a further aspect of the present invention: a protrusion is fixedly installed on the outer surface of the buckle, and the surface of the protrusion away from the partition is flush with the surface of the buckle away from the partition. When it does not move completely around the protrusion, it can push the protrusion and the buckle away from the slot simultaneously.

[0017] As a further aspect of the present invention: the protrusion includes a wedge block rotatably mounted on the buckle, the outer surface of the buckle is provided with a groove for the wedge block to be rotatably positioned, and a third spring is fixedly installed between the groove and the wedge block.

[0018] As a further aspect of the present invention: the third spring causes the wedge to tend to move out of the groove, and when the wedge is stored in the groove, the outer surface of the wedge is flush with the outer surface of the support rod.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: through the cooperation between the main shaft, support rods and telescopic components, a multi-scraper splicing cleaning design is formed. When the telescopic components are in the retracted state, a clearance space is formed between adjacent support rods that allows the support components to pass through. The individual scraper and corresponding support components can be independently disassembled and replaced without disassembling the main shaft and using tools. This significantly simplifies the maintenance process of the cleaning structure, shortens the equipment downtime for maintenance, and reduces the difficulty of manual operation and maintenance costs.

[0020] Through the cooperation between the support rod, limiting component and support component, the limiting component provides radial floating capability for the support component and scraper. When there are large clumps of material on the belt surface, the scraper can automatically retract with the force of the material, effectively avoiding scraper jamming, breakage and belt scratches, improving the operating stability of the cleaning device and extending the service life of the scraper and belt.

[0021] Meanwhile, the limiting component can provide effective positional limitation for the support component based on the support rod, so that the support rod, limiting component, support component and scraper form a stable limiting assembly system, ensuring that each scraper is tightly spliced ​​and accurately positioned.

[0022] Furthermore, based on the modular design, the scraper integrates the support components with the positioning and installation structure of the main shaft and the floating support structure of the slide plate driving the scraper, forming a limit component that is independently separated and installed on the support rod. When a single scraper is worn or damaged, only the corresponding failed scraper and support component need to be replaced. The limit component does not need to be disassembled and replaced, effectively reducing disassembly trouble and spare parts loss, and reducing long-term maintenance costs.

[0034] Example 1:

[0035] Please see Figures 1 to 6 This invention provides a belt conveyor tail cleaning structure, suitable for effectively cleaning the tail of the belt conveyor 2. The cleaning structure in this embodiment is one group within a comprehensive cleaning system and can be set as the first or second group at the tail, serving the purpose of scraping off waste materials. Figure 1 As shown, the whole includes a housing 1 and a belt mechanism 2 disposed on the housing 1. The inside of the housing 1 is provided with a cleaning structure that fits into the belt mechanism 2. The cleaning structure corresponds to the lower or front edge of the belt mechanism 2. The specific structure and working principle of the housing 1 and the belt mechanism 2 can be selected from the prior art. The present invention will not elaborate further. The technical solution of the present invention will be described in detail below in conjunction with the improvement of the cleaning structure.

[0036] Furthermore, such as Figure 2As shown, the cleaning structure includes two main shafts 4 and several scrapers 3. In this embodiment, there are four scrapers 3 arranged side by side. Four support rods 5 are arranged axially between the two main shafts 4. A telescopic component 6 is provided between two adjacent support rods 5. The telescopic component 6 can realize the relative positioning between two adjacent support rods 5, thereby limiting the position of the four support rods 5. A support component 7 for fixing the scraper 3 is sleeved on the outer surface of the support rod 5, and a limiting component 8 for positioning the support component 7 is provided through the outer surface of the support rod 5. When the position of the support rod 5 is limited, the position of the scraper 3 can also be limited by the support component 7 and the limiting component 8, thereby allowing the four scrapers 3 to be spliced ​​together side by side.

[0037] In this embodiment, the telescopic component 6 not only fixes adjacent support rods 5, but also creates an exposed space between two adjacent support rods 5. The support component 7 can then be fitted into the outer surface of the support rod 5 through this space, allowing for quick assembly and disassembly of the scraper 3 without disassembling the main shaft 4. Furthermore, the limiting component 8 not only provides effective positioning for the support component 7, but also allows the support component 7 and the scraper 3 to have a floating space along the radial direction of the support rod 5. This provides the scraper 3 with clearance space, enabling automatic avoidance when encountering large clumps of waste material on the belt mechanism 2.

[0038] Reference Figure 2 In an optional embodiment of the present invention, the two support rods 5 located on both sides are fixedly connected to the two main shafts 4, and the two adjacent support rods 5 are relatively fixed by the telescopic assembly 6. At this time, the positions of the four support rods 5 can be effectively defined in sequence, providing a good basis for defining the positions of the four scrapers 3.

[0039] Reference Figures 3 to 5 In an optional embodiment of the present invention, the telescopic component 6 includes a sleeve 603 slidably mounted to the support rod 5. A first spring 604 is fixedly mounted between one end of the sleeve 603 and the support rod 5. The first spring 604 causes the sleeve 603 to tend to extend out of the support rod 5. A partition 601 is fixedly mounted at the other end of the sleeve 603. A plurality of buckles 602 are fixedly mounted on the surface of the partition 601 away from the sleeve 603. The buckles 602 are used to insert into the outer surface of adjacent support rods 5 to define the position of two adjacent support rods 5. Correspondingly, a slot 501 adapted to the buckle 602 is opened on the outer surface of the adjacent support rod 5. Under the action of the first spring 604, the buckle 602 can move automatically towards the slot 501 to form a lock and complete the positioning of the two adjacent support rods 5.

[0040] In the above structure, such as Figure 3As shown, the support rod 5 is installed in the support rod 5 on the right side of two adjacent support rods 5, and the slot 501 is also opened at the right end of the support rod 5. When the support rod 5 is located in the support rod 5 on the left side of two adjacent support rods 5, the slot 501 is also opened at the left end of the support rod 5 accordingly; its specific direction can be adjusted according to actual needs.

[0041] Reference Figures 4 to 6 In an optional embodiment of the present invention, the limiting component 8 includes a connecting rod 801 slidably mounted on the support rod 5. The connecting rod 801 is used to position the support component 7 and slides along the radial direction of the support rod 5. A second spring 802 is fixedly installed between the connecting rod 801 and the inner wall of the support rod 5. Under the action of the second spring 802, the connecting rod 801 tends to extend out of the support rod 5. At this time, the connecting rod 801 can drive the scraper 3 to also have a moving space through the limiting component 8, thereby making the scraper 3 have a floating space. Here, the second spring 802 simultaneously realizes the floating positioning support of the connecting rod 801 and the scraper 3.

[0042] Reference Figures 3 to 5 In an optional embodiment of the present invention, the support assembly 7 includes an incomplete ring 701 sleeved on the outer surface of the support rod 5 and movably engaged with the connecting rod 801. Two brackets 702 are fixedly installed on the outer surface of the incomplete ring 701. Slide plates 704 are slidably installed inside the two brackets 702. A retainer 703 for fixing the scraper 3 is fixedly installed on the top of the slide plate 704. The connecting rod 801 and the two slide plates 704 are fixedly connected by bolts. Here, the connecting rod 801 simultaneously defines the positions of the slide plate 704, the incomplete ring 701 and the scraper 3.

[0043] Among them, such as Figure 4 As shown, the incomplete ring 701 has a first notch 705 and a second notch 706 along the circumferential direction, and the second notch 706 is connected to the first notch 705. The length of the first notch 705 along the circumferential direction of the main shaft 4 is greater than or equal to the length of the connecting rod 801 along the circumferential direction of the main shaft 4. At this time, the incomplete ring 701 can move along the main shaft 4 to allow the connecting rod 801 to enter the first notch 705. The length of the second notch 706 along the axial direction of the main shaft 4 is equal to the length of the connecting rod 801 along the axial direction of the main shaft 4. At this time, the connecting rod 801 can move from the first notch 705 to the second notch 706. After the connecting rod 801 enters the second notch 706, the inner walls of the two sides of the second notch 706 can respectively fit into the two side walls of the connecting rod 801. This limits the position of the incomplete ring 701, and the positions of the bracket 702, the slide plate 704, the retainer 703 and the scraper 3 can also be limited.

[0044] Furthermore, such as Figure 4 and Figure 6As shown, through holes 803 are provided on the surface of the connecting rod 801 and the surfaces of the two sliding plates 704. When the connecting rod 801 enters the second notch 706 and abuts against it, and the connecting rod 801 and the two sliding plates 704 are relatively fixed through the through holes 803 and bolts, the connecting rod 801 and the incomplete ring 701 can be relatively fixed, and the connecting rod 801 drives the sliding plate 704 to slide up and down based on the sliding plate 704, thereby giving the scraper 3 a floating avoidance space.

[0045] It should be noted that the two outermost support rods 5 are fixed on the main shaft 4 and cannot move left or right, so the corresponding scrapers 3 on these two support rods 5 also cannot move left or right. Therefore, the corresponding scrapers 3 on the middle support rod 5 can also be limited in the middle, so that the position of the middle support rod 5 is stabilized accordingly. Thus, the connecting rod 801 integrates the positioning and installation function of the incomplete ring 701 based on the main shaft 4 and the floating support function of the slide plate 704 driving the scraper 3.

[0046] It should also be noted that when the partition 601 causes the buckle 602 to separate from the slot 501 and the surface of the partition 601 away from the buckle 602 moves into contact with the end of the corresponding support rod 5, the distance between the surface of the buckle 602 away from the partition 601 and the edge of the slot 501 is greater than or equal to the length of the incomplete ring 701 along the axial direction of the main shaft 4. This allows the incomplete ring 701 to pass through the space formed between the buckle 602 and the corresponding support rod 5 when the partition 601 causes the buckle 602 to separate and the partition 601 abuts against another support rod 5. This allows the incomplete ring 701 to be quickly disassembled and assembled between two adjacent support rods 5.

[0047] In summary, through the cooperation of the main shaft 4, support rod 5, buckle 602 and slot 501, based on the design of multi-scraper 3 splicing cleaning, when the buckle 602 is disengaged from the slot 501, a clearance space is formed between adjacent support rods 5, allowing the incomplete ring 701 to pass through. The individual scraper 3 and its corresponding support component 7 can be independently disassembled and replaced without disassembling the main shaft 4 and using tools. This significantly simplifies the maintenance process of the cleaning structure, shortens the equipment downtime for maintenance, and reduces the difficulty of manual operation and maintenance costs.

[0048] Through the cooperation of structures such as support rod 5, incomplete ring 701, connecting rod 801 and second spring 802, the elastic support of the second spring 802 enables the connecting rod 801 and scraper 3 to have radial floating capability. When there are large clumps of material on the belt surface, the scraper 3 can automatically retract with the force of the material, effectively avoiding scraper 3 jamming, breakage and belt scratches, improving the operational stability of the cleaning device and extending the service life of scraper 3 and belt.

[0049] Meanwhile, the connecting rod 801 can also be used to limit the position of the incomplete ring 701. The incomplete ring 701 can quickly pass through the connecting rod 801 with the help of the first notch 705, and the axial positioning of the incomplete ring 701 can be achieved with the help of the second notch 706. Combined with the bolt connection between the slide plate 704 and the connecting rod 801, a stable limiting assembly system is formed to ensure that each scraper 3 is tightly spliced ​​and accurately positioned.

[0050] Furthermore, based on the modular design, the scraper 3 separates the incomplete ring 701 based on the positioning and mounting structure of the main shaft 4 and the floating support structure of the slide plate 704 that drives the scraper 3 into a limiting component 8, which is independently installed on the support rod 5. When a single scraper 3 is worn or damaged, only the corresponding failed scraper 3 and support component 7 need to be replaced. The positioning and mounting structure of the incomplete ring 701 and the floating support structure of the scraper 3 do not need to be disassembled and replaced, effectively reducing disassembly trouble and spare parts consumption, and reducing long-term maintenance costs.

[0051] Please see Figure 7 Considering that the outer surface of the buckle 602 is flush with the outer surface of the support rod 5, it would be inconvenient to move the position of the partition 601. Therefore, a protrusion 9 is fixedly installed on the outer surface of the buckle 602. The surface of the protrusion 9 away from the partition 601 is flush with the surface of the buckle 602 away from the partition 601. When the incomplete ring 701 moves to the right and contacts the protrusion 9, it can push the protrusion 9 and the buckle 602 to the right, so that the buckle 602 separates from the slot 501 and forms a space between the buckle 602 and the slot 501 for the incomplete ring 701 to disengage. This allows for one-handed disassembly and assembly of the incomplete ring 701, thereby further improving the disassembly and assembly efficiency of the incomplete ring 701 and the scraper 3. The protrusion 9 also makes it easier for the staff to move the buckle 602, which is beneficial for the subsequent replacement of the buckle 602 with a new support component 7 and scraper 3.

[0052] Please see Figure 8 and Figure 9Considering that the protrusion 9 is based on the buckle 602 and the direction of movement is limited, the incomplete ring 701 can only move from the side of the protrusion 9 away from the partition 601 toward the protrusion 9. If it moves from the other side toward the protrusion 9, it will be blocked by the protrusion 9 and will not be able to separate the buckle 602 from the slot 501 or enter the space formed after the buckle 602 and the slot 501 are separated. Therefore, the protrusion 9 is improved to include a wedge 901 rotatably mounted on the buckle 602. The wedge 901 can rotate based on the buckle 602 and a groove 605 is provided on the outer surface of the buckle 602 for the wedge 901 to be placed. A third spring 903 is fixedly installed between the groove 605 and the wedge 901. Under the action of the third spring 903, the wedge 901 has a tendency to move out of the groove 605. The top surface of the wedge 901 near the slot 501 is provided with an arc surface 902 that matches the groove 605, so that the wedge 901 can be smoothly retracted into the groove 605.

[0053] In the above structure, such as Figure 9 As shown, the wedge 901 still has a flat surface for contacting the side wall of the incomplete ring 701, and its arc surface 902 is located on the side of the flat surface away from the groove 605. This design allows the incomplete ring 701 to contact the flat surface and move synchronously with the wedge 901, the buckle 602, and the partition 601 when it moves from the left side of the support rod 5 toward the wedge 901. When the incomplete ring 701 moves from the right side of the support rod 5 toward the wedge 901, it can first squeeze the wedge 901 into the groove 605 and squeeze the third spring 903. After the incomplete ring 701 passes the wedge 901, the wedge 901 can be reset and extended under the action of the third spring 903 (after the wedge 901 is stored in the groove 605, the outer surface of the wedge 901 is flush with the outer surface of the support rod 5). At this time, the incomplete ring 701 can move from the left side toward the wedge 901, pushing the buckle 602 to move and creating a space for disengagement.

[0054] In summary, through the cooperation of structures such as buckle 602, wedge 901, third spring 903, and groove 605, when the incomplete ring 701 moves from the left to the wedge 901, it can directly push buckle 602 to move to form a separation space. When it moves from the right to the wedge 901, it can first pass over the wedge 901 and then push buckle 602 to move to form a separation space. At this time, it does not interfere with the quick assembly and disassembly of the incomplete ring 701 and scraper 3 based on support rod 5, and also makes it feasible for the incomplete ring 701 to quickly detach from both sides of support rod 5, thus making it more practical.

[0055] Based on the above design, the overall working principle of the belt conveyor tail cleaning structure is explained below:

[0056] S1. First, fix the main shaft 4 on the housing 1, and fix the ends of the side support rods 5 on both sides to the two main shafts 4 respectively to form an overall support base. The middle support rod 5 is sequentially engaged and spliced ​​by the buckle 602 and the slot 501 to achieve the positioning of the overall support rod 5.

[0057] S2. Next, move the buckle 602 to separate it from the slot 501 and create a space. Insert the incomplete ring 701 into the support rod 5 through the space. Move it axially so that the connecting rod 801 enters the first notch 705 and the second notch 706 in sequence. Then fix the connecting rod 801 and the slide plate 704 through the through hole 803 and the bolt to achieve the final fixation of the incomplete ring 701 and the scraper 3. Multiple scrapers 3 are spliced ​​side by side along the axial direction to form a complete cleaning surface.

[0058] After assembly, scraper 3, under the elastic force of the second spring 802, remains in contact with the surface of belt mechanism 2, scraping away the waste material adhering to its surface as the belt runs, thus achieving tail-end cleaning. When there are large clumps of waste material on the belt surface, scraper 3 automatically floats and avoids them with the help of the second spring 802.

[0059] S3. When disassembling scraper 3, the incomplete ring 701 is disengaged from the connecting rod 801 and moved axially along the support rod 5. The support rod 5 pushes the buckle 602 and the partition 601 to move and compress the first spring 604, so that the buckle 602 is disengaged from the slot 501 and a space is formed for the incomplete ring 701 to be disengaged. At this time, scraper 3 and incomplete ring 701 can be quickly removed as a whole. When installing scraper 3 later, step S2 can be repeated.

[0060] The above-disclosed examples are merely preferred embodiments of this application, intended to facilitate understanding and implementation by those skilled in the art. However, they cannot be used to limit the scope of this application. Therefore, equivalent variations made within the scope of this application are still within the scope of this application.
