Description

Technical Field

[0001] The present invention relates to the technical field, and in particular to a fully sealed mud scraper. Background Art

[0002] Scraper conveyors generally transport bulk materials by pulling the scraper chain through a driving unit in a rectangular cross-section and closed machine trough, and transport bulk materials from one location to another designated location. They have been widely used in the transportation of bulk materials in various industries. They are widely used conveying equipment in chemical, coal, metallurgy, mining, food and transportation departments. They are suitable for conveying loose dust, small particles or small blocks and other bulk materials. They can be arranged horizontally, inclined or vertically. In existing scraper conveyors, when the hopper is feeding, materials will overflow through the gap at the lower end of the hopper, and the overflowed materials will enter the casing. If they are not cleaned for a long time, they will accumulate in the conveyor casing. The more the residual materials accumulate, the more it will affect the normal operation of the conveyor and shorten its service life. Therefore, the device needs to be cleaned. However, due to the sealing characteristics of the conveyor, manual cleaning is extremely inconvenient and wastes manpower costs. At the same time, due to the needs of structural installation, there is always a gap between the rotating roller at the tail of the scraper conveyor and the upper support plate, which causes the sticky materials on the scraper to often fall into the rotating roller, which affects the operation of the machine over time, and the cleaning is very troublesome, which seriously reduces the conveying efficiency of the scraper conveyor and easily causes damage to the scraper conveyor and malfunctions. Therefore, it is urgent to make necessary improvements to the existing scraper conveyor. Summary of the invention

[0030] Working process and principle of the present invention:

[0031] The present invention relates to a fully sealed mud scraper machine, which adds materials into an upper hopper, and the materials are scattered under the action of a scattering shaft and enter a supporting plate below the upper hopper, and a driving chain drives the scraper to pass under the upper hopper, and the scraper takes the materials away and transports them to a designated position.

Therefore, it is difficult for the sticky material on the scraper to fall under the supporting plate, reducing unnecessary accumulation of residual materials and avoiding affecting the service life of the equipment and the continuity of production. In addition, a wear-resistant block is provided on the anti-leakage plate. In the process of the drive chain transitioning from the arc segment to the straight segment, the drive chain directly contacts the wear-resistant block by friction, and the friction force in this process is relatively large, thereby reducing the direct wear of the drive chain on the supporting plate and extending the service life of the supporting plate.
