Description

Technical Field

[0001] The invention relates to the technical field of material conveying equipment, in particular to a scraper-type sweeper for a head wheel of a belt conveyor. Background Art

[0002] In industries such as metallurgy, mining, docks, and power generation, bulk material transportation mainly relies on belt conveyors. When conveying bulk materials, there will always be a small amount of material adhering to the surface of the belt, following the movement of the belt, and finally adhering to the surface of some conveyor components or scattering under them, which will cause wear of related conveyor components, increase the driving torque of the conveyor, and pollute the environment.

[0003] For this reason, a head cleaner is installed on the conveyor to solve this problem. The head cleaners commonly used now use scrapers made of various materials to scrape the surface of the conveyor belt to remove adhered materials. However, these cleaners have complex structures and many moving parts. The scrapers are easy to wear and have a short service life. They often require maintenance, are costly, and have a low cost-effectiveness. In addition, the scraping effect on materials with high adhesion is not good. When foreign objects are caught on the cleaner, the normal operation of the conveyor will be endangered. Summary of the invention

At the same time, the driving shaft synchronously drives the driven shaft to rotate through a linkage component, thereby driving the scraper below to rotate synchronously, thereby adjusting the angles of the two scrapers, thereby meeting the debris cleaning work of belt conveyors of different types and speeds.

[0035] (4) In the present invention, by the mutual cooperation among the water tank, the double-piston-rod hydraulic cylinder and the nozzle of the flushing assembly, the water inside the water tank is pressurized by the extrusion plate so that the water flows to the nozzle through the connecting pipe and is sprayed outward by the nozzle to flush the belt conveyor and the first scraper. When the cleaning device finishes working, the mounting frame moves away from the belt conveyor and separates the mounting frame from the horizontally distributed piston rod of the double-piston-rod hydraulic cylinder. At this time, the extrusion plate is reset by the reset spring, and the nozzle stops spraying water. Such a design is conducive to improving the effect of cleaning debris on the surface of the belt conveyor. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] In this embodiment, when the scraper assembly 3 moves toward the belt conveyor 2 to scrape away debris, the flushing assembly 5 can flush the scraper assembly 3 and the surface of the belt conveyor 2 at the same time, and can flush away some debris on the surface of the belt conveyor 2 and debris caught on the scraper assembly 3, thereby improving the debris scraping effect on the conveyor belt of the belt conveyor 2.

[0045] Furthermore, as a preferred embodiment, the scraper assembly 3 includes a mounting frame 34, a driving shaft 32, a driven shaft 36, an adjustment assembly and a linkage assembly. The mounting frame 34 can be operably moved close to or away from the belt conveyor 2. The driving shaft 32 is located above the driven shaft 36 and is arranged parallel to each other. One end of the driving shaft 32 and the driven shaft 36 are both rotatably mounted on the mounting frame 34. The outside of the driving shaft 32 and the outside of the driven shaft 36 are fixedly sleeved with scrapers 31. When one of the scrapers 31 contacts the surface of the conveyor belt of the belt conveyor 2 and the other scraper 31 also contacts the surface of the conveyor belt of the belt conveyor 2, the adjustment assembly is transmission-connected to the driving shaft 32 for driving the driving shaft 32 to rotate so as to adjust the angle of the scraper 31. The linkage assembly is connected between the driving shaft 32 and the driven shaft 36. When the driving shaft 32 rotates, the driven shaft 36 rotates synchronously with it through the linkage assembly.

[0046] In this embodiment, the scraper assembly 3 has two scrapers 31, which are arranged up and down. When one of the scrapers 31 contacts the surface of the conveyor belt of the belt conveyor 2, the other scraper 31 also contacts the surface of the conveyor belt of the belt conveyor 2, thereby achieving a double-layer scraping effect on the conveyor belt of the belt conveyor 2.

[0051] More preferably, the locking rod 35 and the mounting bracket 34 are elastically connected via a spring.

[0052] When the angle of the scraper 31 needs to be adjusted, the locking rod 35 is manually squeezed inward to disengage the locking rod 35 from the locking hole 331, and the handle is turned to adjust the angle of the scraper 31. After the adjustment is completed, the locking rod 35 is released, and the locking rod 35 extends outward into the corresponding locking hole 331 under the action of elastic force to lock the hand wheel 33.

[0053] Furthermore, as a preferred embodiment, the flushing component 5 is arranged on the side of the mounting frame 34 close to the belt conveyor 2, which includes a water tank, a nozzle, a connecting pipe and an extrusion component. The water tank is a top-opening structure, and there is an extrusion plate 57 at the opening of the water tank. The extrusion plate 57 forms a sealed sliding fit with the inner wall of the water tank. The nozzle is installed on the mounting frame 34 and faces the conveyor belt of the bag conveyor and the scraper 31 located on the driving shaft 32. One end of the connecting pipe is connected to the bottom side wall of the water tank and the other end is connected to the nozzle. The extrusion component is transmission-connected to the extrusion plate 57 for extruding the extrusion plate 57 downward so that the extrusion plate 57 squeezes the water in the water tank through the connecting pipe to the nozzle for spraying.

[0055] In this embodiment, through the mutual cooperation among the water tank, double-piston-rod hydraulic cylinder and nozzle components of the flushing assembly 5, the water inside the water tank is pressurized by the extrusion plate 57 so that the water flows to the nozzle through the connecting pipe and is sprayed out by the nozzle to flush the belt conveyor 2 and the first scraper 31. When the cleaning device finishes working, the mounting frame 34 moves away from the belt conveyor 2 and separates the mounting frame 34 from the horizontally distributed piston rod of the double-piston-rod hydraulic cylinder. At this time, the extrusion plate 57 is reset by the reset spring 58, and the nozzle stops spraying water. This design is conducive to improving the effect of cleaning debris on the surface of the belt conveyor 2.
