Description

Technical Field

[0001] The present application relates to the technical field of conveying equipment, and in particular to a surface cleaning device for a flame-retardant conveyor belt. Background Art

[0002] Flame-retardant conveyor belts are essential equipment for coal mine transportation. During use, some material may adhere to the belt's surface. If not cleaned promptly, the accumulated material can easily cause the belt to deviate, impacting normal operation. To address this issue, the inventors have proposed a surface cleaning device for flame-retardant conveyor belts. Utility Model Content

[0003] The present application provides a flame-retardant conveyor belt surface cleaning device to solve the technical problem of material adhering to the surface of the flame-retardant conveyor belt.

[0004] The technical solution of this application is as follows:

[0005] The present application provides a flame-retardant conveyor belt surface cleaning device, which includes: a scraper, a rotating shaft and a support plate;

[0006] The rotating shaft is fixedly connected to the scraper, and the rotating shaft can drive the scraper to rotate. A transmission plate is provided at the end of the rotating shaft;

[0007] The support plate is rotatably connected to the rotating shaft, and a slide groove is provided on the support plate. A slider and a spring are clamped inside the slide groove, and the slider can move along the slide groove under the push of the spring;

[0008] The transmission plate is engaged with the slider, and the thrust of the spring on the slider can make the scraper generate a movement trend to follow the rotation of the shaft.

[0009] By adopting the above technical solution, the thrust generated by the spring on the slider acts on the rotating shaft through the transmission plate, causing the rotating shaft to have a movement tendency to rotate around its own axis, which can keep the scraper and the flame-retardant conveyor belt in close contact. In this way, the scraper can clean the surface of the flame-retardant conveyor belt during operation, which is conducive to scraping off the adhered materials in time.

[0010] In some implementations, a sleeve is sleeved on the rotating shaft, the sleeve is fixedly connected to the rotating shaft, and the transmission plate is fixedly connected to the sleeve.

[0011] In some implementations, the sleeve is bolted to the shaft.

[0012] In some implementations, the transmission plates are symmetrically arranged at both ends of the rotating shaft.

[0013] In some implementations, the transmission plates are arranged along the radial direction of the rotating shaft.

[0014] In some implementations, the slide groove is configured in an arc shape that is coaxially arranged with the rotation axis.

[0015] In some implementations, the chute is configured to be in a major arc shape along a cross section.

[0016] In some implementations, the slider has a connecting portion extending out of the slide slot, and the connecting portion is provided with a slot for clamping the transmission plate.

[0017] In some implementations, the slots are arranged along the radial direction of the rotating shaft.

[0018] In some implementations, an adjustment block is screwed into the sliding groove, and a spring is compressed between the adjustment block and the sliding block. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to make the purpose, technical solutions and advantages of this application clearer, the application is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain this application and are not used to limit this application.

[0028] See also Figure 1-Figure 2In this embodiment, a flame-retardant conveyor belt surface cleaning device includes a scraper 10, a rotating shaft 20 and a support plate 30, wherein the rotating shaft 20 is fixedly connected to the scraper 10, and the rotating shaft 20 can drive the scraper 10 to rotate. A transmission plate 21 is provided at the end of the rotating shaft 20; the support plate 30 is rotatably connected to the rotating shaft 20, and a slide groove 31 is provided on the support plate 30, and a slider 32 and a spring 33 are clamped inside the slide groove 31. The slider 32 can move along the slide groove 31 under the push of the spring 33; the transmission plate 21 is clamped with the slider 32, and the thrust of the spring 33 on the slider 32 can make the scraper 10 produce a movement trend of following the rotation of the rotating shaft 20.

[0029] By adopting the above technical solution, the thrust generated by the spring 33 on the slider 32 acts on the rotating shaft 20 through the transmission plate 21, causing the rotating shaft 20 to have a movement tendency to rotate around its own axis, which can keep the scraper 10 and the flame-retardant conveyor belt 40 in close contact. In this way, the scraper 40 can clean the surface of the flame-retardant conveyor belt 40 during operation, which is conducive to scraping off the adhered materials in time.

[0030] It should be noted that the scraper 10 is fixedly connected to the rotating shaft 20, and the scraper 10 is arranged along the longitudinal direction of the rotating shaft 20. The outer end of the scraper 10 is bent toward the side where the flame retardant conveyor belt 40 is located, and abuts against the surface of the flame retardant conveyor belt 40. A sleeve 22 is sleeved on the rotating shaft 20, and the sleeve 22 is bolted and fixed between the rotating shaft 20. The transmission plate 21 is welded to the sleeve 22, and the transmission plate 21 is arranged as a whole along the radial direction of the rotating shaft 20. The transmission plate 21 remains symmetrically arranged at both ends of the rotating shaft 20.

[0031] The cam 32 is provided with a screw thread on the top of the support plate 30 so that the cam 32 can rotate relative to the support plate 30, and the cam 32 is provided with a screw thread on the top of the support plate 30 so that the cam 32 can rotate relative to the support plate 30.

[0032] It should be understood that the adjustment block 34 forms a threaded connection with the slide groove 31, and the slider 32 forms a sliding snap fit with the slide groove 31, so that the slider 32 can slide along the slide groove 31 under the push of the spring 33 in a compressed state, and utilize the snap fit between the transmission plate 21 and the snap fit of the snap fit 322 to make the transmission plate 21 rotate around the axis of the rotating shaft 20 following the slider 32, and then drive the scraper 10 to rotate through the rotation of the rotating shaft 20.

[0033] It should also be noted that the flame retardant conveyor belt 40 passes over the drive roller 41, the drive roller 41 is mounted on the mounting frame 42, and the support plate 30 is bolted to the mounting frame 42, so that the scraper 10, the rotating shaft 20 and the drive roller 41 are arranged in parallel. Under the push of the spring 33, the scraper 10 has a tendency to rotate counterclockwise following the rotating shaft 20, so that the scraper 10 is closely attached to the surface of the flame retardant conveyor belt 40. During operation, the scraper 10 can scrape off the material adhering to the surface of the flame retardant conveyor belt 40.
