Description

Technical Field

[0001] The invention belongs to the field of belt conveyor cleaning, and in particular relates to a belt conveyor tail roller cleaning system. Background Art

[0002] With the widespread use of conveyors, the characteristics of transported materials are diverse, and the application environment is also relatively harsh. The roller is a key component of the conveyor belt. Improving the quality of the roller will improve the quality of the entire conveyor belt. The internal quality of the roller itself and the wear of the roller by the external environment are the reasons for the roller quality. In order to save costs, increase the life of the product, and make the whole machine run better, it is very important to clean the materials stuck to the roller. In the existing technology, a scraper and a brush structure are often used to clean the roller or the conveyor belt. However, if the swept material is not cleaned in time, it will cause re-sticking. Or for materials with high viscosity, the surface of the roller will stick to some materials because the sweeping amount is not strong and the cleaning is not thorough. If the material is relatively hard, it will accelerate the wear of the roller and the conveyor belt, thereby reducing the life of the roller and the conveyor belt.

[0017] The present invention will be further described in detail below with reference to the embodiments. The advantages and features of the present invention will become clearer as the description proceeds. However, these embodiments are merely exemplary and do not constitute any limitation to the scope of the present invention. It should be understood by those skilled in the art that the details and forms of the technical solutions of the present invention may be modified or replaced without departing from the spirit and scope of the present invention, but such modifications and replacements fall within the scope of protection of the present invention.

[0018] Figure 1 This is a left-side structural diagram of the tail roller cleaning system of the present invention. Figure 2 It is a schematic diagram of the structure of the tail roller cleaning system in the present invention from a top view.

[0019] like Figure 1 and Figure 2 As shown, the present invention provides a belt conveyor tail roller cleaning system, including a fixing device arranged on a frame 9 at the tail of the conveyor, a first scraper 1 and a second scraper 2 arranged on the fixing device, and a first material receiving trough 4 and a second material receiving trough 5 for collecting waste.

[0020] The present invention provides a first scraper 1 and a second scraper 2 to clean the tail roller 8 and the conveyor belt 10 respectively, and collects the cleaned materials in time through the material receiving trough to prevent the secondary sticking of the materials. It can effectively provide a cleaning effect for the tail roller 8 and the conveyor belt 10 and improve the service life of the tail roller 8 and the conveyor belt 10.

[0021] The fixing device includes a first crossbeam 6 and a fixing frame 7. The first crossbeam 6 is arranged on the frame 9 at the tail of the conveyor near the tail roller 8. The fixing frame 7 is connected to the first crossbeam 6 and is arranged above the conveyor belt 10. One end face of the second scraper 2 is connected to the first crossbeam 6, and the other end face with a blade is close to the tail roller 8, that is, the working surface is close to the side surface of the tail roller 8, which is used to scrape off the material attached to the roller. The first crossbeam 6 is arranged close to the tail roller 8, which is conducive to installing the second scraper 2 so that the working surface of the second scraper 2 is close to the side surface of the tail roller 8, thereby improving the cleaning effect. In actual use, an elastic gasket can be used at the installation point of the second scraper 2 and the first crossbeam 6 according to the viscosity and hardness of the material to achieve a buffering effect for the second scraper 2.

[0022] Both ends of the first scraper 1 are mounted on the fixed frame 7 via a linkage mechanism 3. The linkage mechanism 3 includes a first linkage 31, a second linkage 32, and a third linkage 33. One end of the first linkage 31 is connected to the first crossbeam 6 and the other end is hinged to the second linkage 32. One end of the third linkage 33 is connected to the first scraper 1 and the other end is hinged to the second linkage 32. The first scraper 1 is always in contact with the conveyor belt 10 under its own weight, thereby improving the cleaning quality. The first scraper 1 is configured as a V-shape. Due to the action of the linkage mechanism 3, the first scraper 1 is always in contact with the conveyor belt 10 under its own weight. When the material passes through the working surface of the first scraper 1, the first scraper 1 scrapes off the material adhering to the conveyor belt 10 and enters the first material receiving trough 4 below the conveyor belt 10 at the lower end of the fixed frame 7 along the working surface of the first scraper 1 from both sides of the conveyor belt 10.

[0023] A chute plate 11 is provided above the second scraper 2. The chute plate 11 has a straight plate portion and a curved plate portion. Material adhering to the tail drum 8, removed by the second scraper 2, passes through the straight plate portion and slides into the curved plate portion. Centrifugal force then throws the material into the second receiving chute 5. Specifically, the second receiving chute 5 is located above the fixed frame 7, with one end covering the crossbeam and the other end connected to the fixed frame 7.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1) The present invention is designed with a first scraper and a second scraper to clean the tail roller and conveyor belt respectively, and the cleaned materials are collected in time through a material receiving chute to prevent secondary adhesion of the materials. This can effectively provide a cleaning effect on the tail roller and conveyor belt, and extend the service life of the tail roller and conveyor belt.

[0026] 2) The present invention is designed to design the fixing frame to include a first crossbeam and a fixing frame. The first crossbeam is arranged close to the tail drum, which is conducive to installing the second scraper so that the working surface of the second scraper is close to the side surface of the tail drum, thereby improving the cleaning effect. In actual use, an elastic gasket can be used at the installation point of the second scraper and the first crossbeam according to the material viscosity and material hardness to achieve a buffering effect for the second scraper.

[0027] 3) The present invention designs a connecting rod mechanism, one end of which is connected to the first beam, and the other end is connected to the first scraper. Due to the existence of the connecting rod mechanism, the first scraper always sticks to the conveyor belt under the action of its own gravity, thereby improving cleaning efficiency.

[0028] 4) This invention features a chute plate with a straight plate portion and a curved plate portion. Material adhering to the tail roller is removed by the second scraper. After being scraped, it slides through the straight plate portion into the curved plate portion, where centrifugal force throws the material into the second receiving chute. This ensures that the scraped material is accurately delivered to the first receiving chute, preventing it from falling onto the lower frame and conveyor belt, potentially causing secondary adhesion to the roller. This improves cleaning quality and extends the service life of the roller and conveyor belt.

[0029] The above technical features of the present invention are novel, creative and practical in the field of conveyors and crushing. The terms in this technical solution can be explained and understood using patent documents in this technical field.

[0030] The implementation schemes in the above embodiments can be further combined or replaced, and the embodiments are merely descriptions of preferred embodiments of the present invention, and do not limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various changes and improvements made to the technical solutions of the present invention by professional and technical personnel in this field shall fall within the scope of protection of the present invention.
