Description

Technical Field

[0001] This utility model relates to the field of conveyor belt auxiliary mechanical equipment, and in particular to a scraper assembly and a conveyor belt cleaner. Background Technology

[0002] When conveyor belts transport powdery materials, such as coal powder and lime, the materials are prone to sticking to the belt. Although ordinary scraper-type conveyor belt cleaners can solve the problem of timely removal of sticky materials, the scrapers on these cleaners wear out quickly due to prolonged scraping, resulting in a high maintenance frequency and thus increasing the operating cost of the conveyor belt.

[0003] A utility model patent with patent application number 202420578414.1 discloses a novel impact cleaner. This new impact cleaner no longer uses a scraping method, but instead employs a cam, causing the scraper to reciprocate and impact the conveyor belt, promptly removing adhered materials. However, this cam-type operation results in too little impact force; it only causes a certain degree of undulation in the conveyor belt and does not generate significant instantaneous impact, thus the cleaning effect is not ideal. Utility Model Content

[0004] Therefore, it is necessary to provide a scraper assembly and a conveyor belt cleaner to address at least one of the problems mentioned above.

[0005] In the first aspect, the present invention provides a scraper assembly, including a backing seat, a roller, and a swing assembly, wherein the roller and the swing assembly are disposed on the same side of the backing seat;

[0006] The roller is axled onto the abutment seat. The swing assembly includes a traction shaft, a sleeve portion, a swing arm, and a cleaning portion. The first end of the traction shaft is pivotally connected between the rolling center and the rolling edge of the roller. The second end of the traction shaft is inserted into the first end of the sleeve portion. The second end of the sleeve portion is axled onto the abutment seat. The swing arm extends from the side of the sleeve portion. The cleaning portion is disposed at the top end of the sleeve portion.

[0007] In some implementations of the first aspect, the rolling surface of the roller is a toothed surface.

[0032] The technical solution of this utility model and how the technical solution solves the above-mentioned technical problems are described in detail below with specific embodiments.

[0033] An embodiment of the first aspect of this utility model provides a scraper assembly, such as Figure 1 As shown, it includes a support seat 100, a roller 200 and a swing assembly 300, with the roller 200 and the swing assembly 300 disposed on the same side of the support seat 100.

[0034] like Figure 3 As shown, the roller 200 is axially connected to the abutment 100. The swing assembly 300 includes a traction shaft 310, a sleeve portion 320, a swing arm 330, and a cleaning portion 340. The first end of the traction shaft 310 is pivotally connected between the rolling center and the rolling edge of the roller 200. The second end of the traction shaft 310 is inserted from the first end of the sleeve portion 320. The second end of the sleeve portion 320 is axially connected to the abutment 100. The swing arm 330 extends from the side of the sleeve portion 320. The cleaning portion 340 is disposed at the top of the sleeve portion 320.

[0035] By adjusting their positions, both the roller 200 and the cleaning unit 340 can rest against the moving conveyor belt 10, such as... Figures 2-5 As shown, the roller 200 rotates under the drive of the conveyor belt 10. The first end of the traction shaft 310 on the swing assembly 300 is connected to the wheel surface of the roller 200 to form an eccentric rotation structure. The second end of the traction shaft 310 is sleeved in the sleeve portion 320. The traction shaft 310 can reciprocate relative to the sleeve portion 320, thereby realizing that the roller 200 drives the traction shaft 310 to reciprocate and swing. The cleaning part 340 provided on the sleeve portion 320 can swing and clean the conveyor belt 10.

[0036] The conveyor belt cleaner provided by this utility model includes rollers 200 that abut against and press against the surface of the conveyor belt 10. On the one hand, the rollers 200 rotate, and on the other hand, the rollers 200 press against and cut the material adhering to the surface of the conveyor belt, making the material loose. Then, the swing component 300 linked with the rollers 200 sweeps the material off. It can effectively clean the material adhering to the conveyor belt without the need for continuous scraping by a scraper.

[0037] The surface of roller 200 needs to be roughened to improve the reliability of the conveyor belt drive roller 200. In some implementations of the first aspect, such as... Figure 6 As shown, the rolling surface of roller 200 is a toothed surface. Specifically, it can be a gear structure or a sawtooth structure. This structure can break large areas of material adhering to the conveyor belt surface into smaller pieces, which can be directly removed or facilitate subsequent cleaning.

[0038] Optionally, in conjunction with the embodiments of the first aspect and the above implementations, in other implementations of the first aspect, the swing arm 330 is perpendicular to the axis of the sleeve portion 320. The vertical structure of the swing arm 330 and sleeve portion 320 allows for better contact between the swing arm 330 and the cleaning portion 340 on the swing arm 330 and the conveyor belt.

[0039] Optionally, in conjunction with the embodiments of the first aspect and the above implementation methods, in some further embodiments of the first aspect, such as Figure 1 and Figure 3 As shown, a brush body 341 is provided at the top of the sweeping part 340. The top of the sweeping part 340 can be a bristle brush or a wire brush. More specifically, in some implementations, the sweeping part 340 is detachably connected to the swing arm 330. The sweeping part 340 can be connected and installed on the swing arm 330 by plugging it in. When it is necessary to replace the sweeping part 340, it can be directly removed and replaced, which is convenient for maintenance.

[0040] Optionally, in conjunction with the first aspect embodiment and the above implementation, in some further embodiments of the first aspect, such as... Figure 6 As shown, the roller 200 has a slide rail 210 and a fixed slider 220 on its surface. The fixed slider 220 is mounted on the slide rail 210, and the first end of the traction shaft 310 is pivotally connected to the fixed slider 220. By setting the slide rail 210 and the fixed slider 220, and connecting the first end of the traction shaft 310 to the fixed slider 220, the swing amplitude of the traction shaft 310 can be adjusted, thereby adjusting the swing amplitude of the cleaning unit 340 and improving the adaptability of the scraper assembly to various materials on the conveyor belt.

[0041] Optionally, combining the first aspect with the above implementation methods, such as... Figure 1 As shown, the abutment 100 includes a mounting frame 110 and a support beam 120; the roller 200 and the sleeve portion 320 are both axially connected to the mounting frame 110, and one end of the support beam 120 is connected to the mounting frame 110.

[0042] Based on the same technical concept, a second aspect of this utility model also provides a conveyor belt cleaner, including a torsion spring assembly, a base, and a scraper assembly as described in any of the first aspects of this utility model. The torsion spring assembly is disposed within the base, and the abutment 100 is connected to the torsion spring assembly. Multiple scraper assemblies can be arranged side-by-side to facilitate lateral coverage of the conveyor belt.
