Abstract
Description
Technical Field
[0001] The present application relates to the technical field of material pushing, and in particular to a swing arm type flap material pushing device. Background Art
[0002] In the sintering production process, the sintering mixture is mainly transported by belt conveyors. Belt conveyors have large conveying capacity, can continuously transport materials without interruption, and have a high degree of automation, a wide controllable range of conveying speed, and are easy to achieve three-dimensional cross-conveying. In addition, its installation structure is simple, maintenance is convenient, and the cost is low. It can also transport a wide range of materials. The belt conveyor unloading trolley is a separate component of the belt conveyor. It travels on the conveyor and can unload at any point in the horizontal section of the conveyor.
[0003] However, it is difficult to control the spillage of returned materials during transportation on belt conveyors, especially for the mixed iron materials in the sintering batching room, whose main components are concentrate, quicklime, dolomite, coal, sintering dust ash, environmental dust ash, steelmaking ash, returned ore, etc. After secondary heating water mixing and balling by the drum, the moisture content of the mixed material is about 6.7%, and the temperature is about 65°C. At present, the large particles of sticky materials on the working surface of the belt are mainly cleaned by H-type and P-type scrapers, and the cleaning volume is about 75%. The wet mud film adsorbed on the working surface of the belt will form a large amount of material accumulation when passing through the lower rotating roller, which will cause the roller bearing to wear faster or get stuck and not rotate. In severe cases, it will cause the belt to deviate or the belt to be squeezed to death, resulting in a shutdown accident. Summary of the invention
[0004] The purpose of the embodiments of the present application is to provide a swing-arm type flap pushing device, which can solve the technical problems raised by the background technology.
[0005] An embodiment of the present application provides a swing-arm type flip plate pushing device, comprising a frame and a plurality of rotating rollers, wherein the plurality of rotating rollers are rotatably arranged on the frame, a pushing plate is fixedly arranged on the rotating rollers, and stoppers are arranged at both ends of the rotating rollers, one end of the stopper is fixedly arranged on the frame, and the end of the stopper away from the frame abuts against the pushing plate and tilts the pushing plate.
[0006] Furthermore, the number of rotating rollers is two, and the bottoms of the pusher plates on the two rotating rollers are flush with each other.
[0007] Furthermore, a wear-resistant plate is fixedly provided at the lower end of the push plate.
[0008] Furthermore, bearings are provided at both ends of the rotating roller, and the rotating roller is connected to the frame via the bearings.
[0009] Furthermore, the surface of the pusher plate is provided with wear-resistant ceramics.
[0010] Furthermore, the inclination angle of the push plate when abutting against the stopper is 50-70°.
[0011] Beneficial effects of the utility model:
[0012] The utility model arranges a rotating roller rotatably on a frame, a pushing plate is fixedly provided on the rotating roller, and stoppers are provided at both ends of the rotating roller, one end of the stopper is fixedly provided on the frame, and the end of the stopper away from the frame abuts against the pushing plate and makes the pushing plate tilt. When in use, the frame is fixed on the moving frame of the belt conveyor unloading trolley, so that the pushing plate abuts against the belt of the belt conveyor. When the moving frame of the belt conveyor unloading trolley moves, the pushing device is driven to move, and the wet mud film on the conveying belt of the belt conveyor is scraped and pushed, so as to avoid the wet mud film adsorbed on the working surface of the belt to form a large amount of material accumulation when passing through the lower rotating roller, so as to avoid the accelerated wear of the roller bearing or the jamming and non-rotation, and to prevent the belt from running off track or being squeezed to death to cause a shutdown accident.

[0025] like Figure 1 and Figure 2When the material is in the working state, the lifting of the lifting device 11 is in the process of being lifted up, and the lifting of the lifting device 11 is in the process of being lifted up, so that the lifting of the lifting device 11 is in the process of being lifted up, and the lifting of the lifting device 11 is in the process of being lifted up, so that the lifting of the lifting device 11 is in the process of being lifted up, and the lifting of the lifting device 11 is in the process of being lifted up, and the lifting of the lifting device 11 is in the process of being lifted up, and the lifting of the lifting device 11 is in the process of being lifted up
[0026] like Figure 1 As shown, two rotating rollers 2 are provided, and the bottoms of the pushing plates 3 on the two rotating rollers 2 are flush with each other, so that the two pushing plates 3 can play a pushing role at the same time.
[0027] like Figure 2 As shown, a wear-resistant plate 5 is fixedly provided at the lower end of the push plate 3, and the wear-resistant plate 5 abuts against the belt of the belt conveyor to reduce wear and extend the service life.
[0028] like Figure 2 As shown, bearings 6 are provided at both ends of the rotating roller 2, and the rotating roller 2 is connected to the frame 1 through the bearings 6. Specifically, the bearings 6 are welded at the connection between the stopper 4 and the frame 1, and the rotating roller 2 is easier to rotate through the bearings 6.
[0029] like Figure 1 and Figure 2 As shown, the surface of the push plate 3 is provided with wear-resistant ceramics (not shown in the figure) to prevent the push plate 3 from directly contacting the material, reduce the wear of the push plate 3, and extend the service life of the push plate 3.
[0030] like Figure 2 As shown, the inclination angle of the push plate 3 when abutting against the stopper 4 is 50-70°. In this embodiment, the inclination angle of the push plate 3 when abutting against the stopper 4 is 60°. Reasonable inclination scheduling makes it easier to push the wet mud film on the belt conveyor belt.
[0031] Working principle:
[0032] Fix the frame 1 on the mobile frame of the belt conveyor unloading trolley, so that the push plate 3 abuts against the belt of the belt conveyor, and the axial center line of the rotating roller 2 is perpendicular to the longitudinal center line of the belt conveyor unloading trolley, such as Figure 2As shown, when the belt is operating normally in production, when the belt conveyor unloading trolley starts to move from left to right, it is a pushing process. At this time, the pushing plate 3 rotates clockwise along the rotating roller 2 until the stopper 4 is away from the end of the frame 1. At this time, the pushing flap forms an angle of 60° with the horizontal plane, and the scattered accumulated materials are pushed into the head bin of the sintering machine as the belt conveyor unloading trolley runs; when the belt conveyor unloading trolley starts to move from right to left, it is a return process. The pushing plate 3 rotates counterclockwise along the rotating roller 2 under the reaction force, and the pushing plate 3 rises about 15 mm. When it reaches the starting point, the moving trolley automatically stops to complete the material clearing process and automatically enters the next cycle.
[0033] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
