Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and more specifically, to a modular segmented, fully adjustable belt conveyor cleaning device. Background Technology

[0002] Traditional solid-plate elastic polyurethane scrapers are prone to frictional and internal heat generation during cleaning, affecting the hardness of the polyurethane elastomer. They are also susceptible to acid and alkali corrosion when handling waste materials. When the scraper's hardness decreases or it corrodes, high-viscosity, easily sticky material particles can penetrate between the conveyor belt and the scraper, causing separation and making it impossible to effectively remove material adhering to the conveyor belt. This sticky material layer leads to material accumulation on the rollers and idlers, causing rollers to become out of round, belt misalignment and slippage, and the conveying capacity failing to meet design requirements. Furthermore, during material transport, most of the material concentrates in the middle, leading to wear in the middle section. The wear is more severe on both sides. When the wear reaches a certain level, a dent appears in the middle of the belt. In this case, the whole scraper will stick to the sides of the belt, but not to the middle. When the belt dries, as the belt runs, the sticky material layer falls off in fragments, causing material to spill along the conveyor belt and making cleaning difficult. Compared with the multi-segment cleaners on the market, it cannot be adjusted in all directions. The scraper bracket cannot rotate independently, and the scraper is fixedly installed, which makes it impossible for some scrapers to stick vertically to the belt. At the same time, it will form point contact between the scraper and the belt instead of line contact, resulting in poor scraping effect and a high risk of tearing the belt. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a modular segmented fully adjustable belt conveyor cleaning device, which ensures that all scrapers can achieve vertical and tight contact with any contact surface of the belt and have good clamping force.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a modular segmented all-angle adjustable belt conveyor cleaning device is constructed and installed on the steel plates on both sides of the head pulley cover of the belt conveyor. It includes a base and a scraper device and an adjustment device installed on the base. The scraper device includes a scraper, a rubber torsion spring, a fixing pin, a scraper frame base and a scraper frame top rod. The adjustment device is provided with a base support. Multiple fixing pins pass through the inner hole of the rubber torsion spring. The two ends of the fixing pins are inserted into pressure blocks. The pressure blocks are fixed on the base support. The scraper frame base is clamped to the outer shell of the rubber torsion spring. Twisting the scraper frame base causes the rubber torsion spring to provide a reaction force to push the scraper against the belt surface.

[0005] According to the above scheme, the adjustment device further includes a longitudinal locking nut and a longitudinal adjusting screw. The base bracket is fixedly connected to the middle part of the longitudinal adjusting screw through the longitudinal locking nut, and the two ends of the longitudinal adjusting screw are mounted on the C-shaped frame.

[0006] According to the above scheme, the adjustment device further includes a lateral adjustment screw, a lateral adjustment block, and a lateral adjustment locking nut. The end of the base bracket is in contact with the lateral adjustment screw, and the lateral adjustment screw is mounted on the C-shaped frame through the lateral adjustment block and the lateral adjustment locking nut.

[0007] According to the above scheme, the scraper frame top rod is provided with a waist hole, the scraper frame base is provided with a round hole, and the scraper frame top rod is connected by a slotted pin after being sleeved into the scraper frame base.

[0008] According to the above scheme, the inner hole of the scraper frame top rod and the outer circle of the scraper frame base are clearance fit, the groove pin and the scraper frame base are interference fit, and the scraper frame top rod can rotate freely around the axial direction.

[0009] According to the above scheme, the scraper frame base is fastened with open bolts.

[0010] According to the above scheme, the upper end of the scraper frame top rod is connected to the scraper by bolts, and the scraper is locked on the step of the top rod.

[0011] According to the above scheme, the bolt holes on the scraper are centered holes.

[0012] According to the above scheme, the scraper devices are installed in parallel on the base in a staggered manner, and the spacing between them along the axial direction of the base is less than the width of the scraper.

[0013] According to the above scheme, the base support is a cylindrical rotatable base support.

[0014] The modular, segmented, fully adjustable belt conveyor cleaning device of this utility model has the following beneficial effects:

[0015] 1. The scraper driven by the rubber torsion spring elastic element of this utility model has excellent dynamic compensation performance. The scraper has good tracking performance of the conveyor belt, and the material is not easily squeezed between the scraper and the belt, and the cutter head is not easy to accumulate material. The free swing of the axis of the top rod allows the top surface of the scraper to form line contact with the belt, realizing equal contact force between the scraper and the belt, ensuring that the entire scraper surface scrapes the material without damaging the belt and extending its service life. The scraper unit adopts a vertical scraper rod and a parallel plane with the belt, which can be used in narrow installation positions and has a wider range of applications.

[0016] 2. When the adjusting device presses the scraper assembly to contact the belt surface, the scraper can swing freely to a certain extent, so it can adapt well to the repaired or worn belt surface, making it a complete line contact rather than a point contact. This can effectively protect the belt from being cut while completely cleaning the material. Attached Figure Description

[0022] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figure 1-4 As shown, the modular segmented fully adjustable belt conveyor cleaning device of this utility model is installed on the steel plates on both sides of the belt conveyor head wheel cover 3, including a base 2 and a scraper device 1 and an adjustment device 4 installed on the base.

[0024] The scraper device 1 includes a scraper 9, a rubber torsion spring 13, fixing pins 14, a scraper frame base 15, and a scraper frame top rod 16. The adjusting device 4 is equipped with a base bracket 8. Multiple fixing pins 14 pass through the inner holes of the rubber torsion spring 13, with both ends of the fixing pins 14 inserted into pressure blocks 10. The pressure blocks 10 are fixed to the base bracket 8, forming a central fixation of the rubber torsion spring 13. The scraper frame base 15 clamps onto the outer shell of the rubber torsion spring 13, and torsion of the scraper frame base 15 causes the rubber torsion spring 13 to provide a reaction force that pushes the scraper against the belt surface.

[0025] The clamping force of the scraper 9 on the belt is generated by the relative torsion of the inner core and outer shell of the rubber torsion spring 13. The scraper frame base 15 is fitted onto the outer shell of the rubber torsion spring 13, and the opening of the scraper 9 is narrowed by bolt fasteners to generate a clamping force on the outer shell of the rubber torsion spring 13, thereby fixing it to the outer shell of the rubber torsion spring 13. The scraper 9, the scraper frame top rod 16 and the scraper frame base 15 are a whole unit and are lifted upward by the adjusting device 4. When the scraper 9 contacts the belt and generates a certain torsion, the rubber torsion spring 13 rotates relative to the inner and outer sides. The rubber at its center outputs a reaction torque to the scraper device 1, so that the scraper 9 fits tightly against the surface of the belt, ensuring that no material enters between the scraper 9 and the belt during operation.

[0026] Preferably, the adjusting device further includes a longitudinal locking nut 6 and a longitudinal adjusting screw 7. The base bracket 8 is fixedly connected to the middle of the longitudinal adjusting screw 7 via the longitudinal locking nut 6, and both ends of the longitudinal adjusting screw 7 are mounted on the C-shaped frame. The adjusting device also includes a transverse adjusting screw 5, a transverse adjusting block 12, and a transverse adjusting locking nut 11. The end of the base bracket 8 contacts the transverse adjusting screw 5, and the transverse adjusting screw 5 is mounted on the C-shaped frame via the transverse adjusting block 12 and the transverse adjusting locking nut 11.

[0027] The scraper frame base can be adjusted omnidirectionally by using the lateral adjusting screw 5 and the longitudinal adjusting screw 7. When the device needs to be adjusted vertically as a whole, loosen the longitudinal locking nut 6 and rotate the longitudinal adjusting screw 7; when the device needs to be adjusted horizontally as a whole, loosen the lateral adjusting locking nut 11 and rotate the lateral adjusting block 12, which will allow the lateral adjusting screw 5, which is welded to the mounting base bracket 8 of the scraper device 1, to move left and right. This allows for omnidirectional movement of the device, greatly facilitating installation and adjustment.

[0028] Preferably, the scraper frame top rod 16 is provided with a waist hole, and the scraper frame base 15 is provided with a round hole. After the scraper frame top rod 16 is fitted into the scraper frame base 15, the two are connected by a slotted pin 17. The inner hole of the scraper frame top rod 16 and the outer circle of the scraper frame base 15 are clearance fit, and the slotted pin 17 and the scraper frame base 15 are interference fit. The scraper frame top rod 16 can rotate freely around the axial direction. The scraper 9 installed at the top of the scraper frame top rod 16 can adaptively rotate to form line contact when in contact with the belt, ensuring the scraping effect while effectively protecting the belt from damage due to point contact.

[0029] Preferably, the scraper frame base 15 is fastened with open bolts. Loosening the bolts allows it to rotate freely on the housing of the rubber torsion spring 13, so that its initial installation angle can be adjusted according to the actual condition of the belt surface, ensuring that the scraper 9 can be pressed vertically against the belt surface.

[0030] Preferably, the scraper 9 is connected to the scraper frame top rod 16 at the upper end by bolts and is locked on the step of the scraper frame top rod 16. At the same time, 9 is a centering hole, which can be rotated 180° for use after one side is worn, thus doubling the service life.

[0031] Preferably, the scraper devices 1 are installed in parallel and staggered arrangement on the base 2 to ensure that the scrapers 9 do not interfere with each other when they move, and the spacing between them in the axial direction of the base 2 is less than the width of the scrapers 9 to ensure that the scrapers 9 overlap each other by a certain distance in the axial direction.

[0032] Preferably, the base support 8 is a cylindrical rotatable base support that can be freely rotated to adjust the installation angle of the overall scraping device 1.

[0033] The advantages of this utility model are as follows:

[0034] 1. Full line contact: The scraper is installed on a guide rod with a certain degree of free swing around the axis. When the adjusting device presses the scraper assembly to contact the belt surface, the scraper can swing freely to a certain extent, so it can adapt well to the repaired or worn belt surface, making it a complete line contact rather than a point contact. While completely cleaning the material, it can effectively protect the belt from being cut.

[0035] 2. Superior practicality of the scraper: The scraper is made of hard alloy, which has excellent wear resistance and scraping performance for high belt speed and high viscosity materials. It is also extremely wear-resistant, and materials are not easily squeezed between the scraper belt, so it is not easy for material to accumulate or stick. At the same time, unlike embedded scrapers, this scraper is fixed to the scraper frame with bolts, and the scraper is designed symmetrically with a cross center line. When the blade edge on one side is severely worn, it can be rotated 180° for installation, which doubles the service life and greatly reduces the cost of use and maintenance.

[0036] 3. The dual-rotation setting ensures good scraper fit; the mounting base of the scraper device assembly is a cylindrical design. The entire scraper device can be adjusted by rotating the base by loosening the bolts and set screws holding the base; the scraper device base is clamped to the circular housing of the rubber spring. By loosening the clamp bolts and rotating the scraper frame, the independent angle rotation of a single scraper frame can be achieved, so that each scraper unit can fit perfectly with the belt.

[0037] 4. The omnidirectional adjustment device facilitates installation and positioning; the brackets on both sides of the scraper device mounting base are connected or pass through by longitudinal and transverse screws, which can achieve omnidirectional adjustment. The initial positioning of the device does not require high positional accuracy. After positioning, the longitudinal and transverse screws can be adjusted to make the device reach the ideal position, which can save a lot of installation time.

[0038] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims. All of these forms are within the protection scope of the present invention.
