Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, in particular to a belt surface cleaning device for a belt conveyor. Background Art

[0002] As an important material conveying equipment in the mineral processing production process, the belt conveyor plays an important role in material conveying and transportation. In the process of conveying wet mineral materials, the wet mineral materials are very easy to adhere to the surface of the belt to form sticky materials. After the sticky materials enter the tail belt roller with the belt running, they will tear and roughen the surface glue of the belt, accelerating the wear of the belt. And as the sticky materials on the surface of the roller become more and more sticky, the adhesion will increase, causing the belt to deviate, resulting in serious consequences. In order to solve the above-mentioned sticky material phenomenon, a belt cleaning structure is usually set under the power roller of the belt conveyor head. The belt cleaning structure includes a scraper device with a scraper plate as the main component. In order to ensure the cleaning effect, it is necessary to ensure that the scraper plate of the belt cleaning structure is always in contact with the belt on the roller. However, in actual use, due to the high hardness of the adhered mineral, the scraper plate is severely worn, and the scraper plate needs to be replaced frequently to ensure the cleaning effect. However, the lower part of the replaced scraper plate is intact. Due to the fixed limitation of the scraper plate installation structure, it cannot be used any longer, resulting in a waste of resources and an increase in the consumption cost of the mineral processing enterprise. Utility Model Content

[0003] The utility model aims to provide a belt conveyor belt surface cleaning device, which can improve the utilization rate of the scraper plate and reduce the consumption cost of the enterprise while ensuring the cleaning effect.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A belt conveyor belt surface cleaning device comprises a triangular scraper plate mounting frame and an adjusting mechanism connected to the scraper plate mounting frame, wherein the two ends of the bottom of the scraper plate mounting frame are respectively hinged to the longitudinal beam of the belt conveyor support frame, and the pointed end faces the direction opposite to the return direction of the belt; the adjusting mechanism comprises a first adjusting rod, a telescopic sleeve and a second adjusting rod threadedly connected to the telescopic sleeve, one end of the first adjusting rod is hinged to the pointed end of the scraper plate mounting frame, and the other end is inserted into the telescopic sleeve and slidably connected to the telescopic sleeve; one end of the second adjusting rod is inserted into the telescopic sleeve and threadedly connected to the telescopic sleeve, and the other end is hinged to the crossbeam of the belt conveyor support frame; a spring is installed in the telescopic sleeve, and the two ends of the spring are respectively abutted against the first adjusting rod and the second adjusting rod.

[0006] Compared with the prior art, the utility model has the following beneficial effects:

[0007] When the triangular scraper plate mounting frame is lifted up, the rubber scraper plate can be stably kept in contact with the outgoing belt of the belt conveyor under the action of the spring elastic force, and the hardness of the spring can be adjusted by rotating the telescopic sleeve to always keep the scraper plate tightly combined with the belt, thereby improving the utilization rate of the scraper plate and avoiding waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 It is a bottom view of the structure of the utility model.

[0009] Figure 2 It is a structural side view of the utility model.

[0010] In the figure, 1-scraper plate mounting frame, 2-first adjusting rod, 3-telescopic sleeve, 4-second adjusting rod, 5-spring, 6-rubber scraper plate. DETAILED DESCRIPTION

[0011] The utility model is further explained below in conjunction with the accompanying drawings.

[0012] like Figure 1-2 As shown, a belt conveyor belt surface cleaning device comprises a triangular scraper plate mounting frame 1 and an adjusting mechanism connected to the scraper plate mounting frame 1, a rubber scraper plate 6 is fixedly installed on the top of the scraper plate mounting frame 1 by bolts, and the two ends of the bottom are respectively hinged to the longitudinal beams of the belt conveyor support frame, and the pointed part faces the direction opposite to the return direction of the belt; the adjusting mechanism comprises a first adjusting rod 2, a telescopic sleeve 3 and a second adjusting rod 4 screwed to the telescopic sleeve 3, one end of the first adjusting rod 2 is hinged to the pointed part of the scraper plate mounting frame 1, and the other end is inserted into the telescopic sleeve 3 and abuts against one end of a spring 5 installed in the telescopic sleeve 3, the other end of the spring 5 abuts against one end of the second adjusting rod 4 screwed, and the other end of the second adjusting rod 4 is hinged to the crossbeam of the belt conveyor support frame.

[0013] When in use, the extension amount of the first adjusting rod 2 and the second adjusting rod 4 can be adjusted by rotating the telescopic sleeve 3, and then the angle of attack of the scraper plate mounting frame 1 can be adjusted to ensure that the rubber scraper plate 6 is always in contact with the return belt of the belt conveyor under the action of the elastic force of the spring 5, so as to achieve scraping and cleaning; and in the scraping process, the tip direction of the scraper plate mounting frame 1 is opposite to the forward direction of the return belt, forming a broken arch posture, so that the mud and water adhered to the bottom of the belt automatically move to both sides and fall off, reducing the amount of mud and water falling into the belt corridor and protecting the belt rollers.

[0014] In summary, the belt surface cleaning device of the belt conveyor of the utility model improves the utilization rate of a single rubber scraper plate, reduces the replacement frequency of the rubber scraper plate, ensures the continuity of the mineral processing operation, and reduces the production cost of the enterprise.
