Description

TECHNICAL FIELD

[0001] The utility model relates to the screen cleaning field especially relates to an automatic mud scraping device. BACKGROUND

[0002] When the vibrating screening equipment encounters material with high viscosity, the screen is bonded with sundries, causing overflow or reducing the screening processing capacity, increasing the disposal cost, and often requiring a dedicated post to scrape off the sundries on the screen surface, which is high in labor intensity. SUMMARY

[0003] The utility model discloses an automatic mud scraping device, which solves the problems in the background technology.

[0004] To achieve the above object, the utility model provides the following technical scheme:

[0005] An automatic mud scraping device includes a brush, a guide rail, a hydraulic cylinder and a fixed seat. The rear end connecting rod of the brush is installed on the guide rail. The guide rail is provided with an advancing slope track and a return horizontal track. When the rear end connecting rod of the brush moves forward, it moves along the advancing slope track in the guide rail, causing the front brush to lift and move away from the surface of the screen, thereby avoiding affecting the normal operation of the material. When the rear end connecting rod of the brush moves backward, it moves along the return horizontal track in the guide rail, causing the brush to approach the screen surface and clean the screen. The rear end connecting rod of the brush is installed at the front end of the hydraulic cylinder, and the brush moves forward and backward in the guide rail by the hydraulic cylinder. The rear end of the hydraulic cylinder is installed on the fixed seat, and the brush is installed on the top of the screen inlet by the fixed seat.

[0006] The utility model has the advantages of reasonable design, automatic operation instead of manual operation, saving labor and environmental protection, and improving the processing efficiency and effect of the screening equipment for sticky materials. BRIEF DESCRIPTION OF DRAWINGS

[0007] Figure 1 The utility model discloses an automatic mud scraping device.

[0008] In the figure: 1, brush, 2, guide rail, 3, hydraulic cylinder, 4, fixed seat. DETAILED DESCRIPTION

[0009] The utility model will be further described in combination with the drawings and specific embodiments:

[0010] For example, Figure 1As shown, an automatic mud scraping device comprises a brush 1, a guide rail 2, a hydraulic cylinder 3, a fixed seat 4, the connecting rod at the rear end of the brush 1 is installed on the guide rail 2, the guide rail 2 is provided with an advancing inclined track and a returning horizontal track, when the connecting rod at the rear end of the brush 1 moves forward, it moves along the advancing inclined track in the guide rail 2, so that the front brush 1 is lifted away from the screen surface, thereby avoiding affecting the normal operation of the material, when the connecting rod at the rear end of the brush 1 moves back, it moves along the returning horizontal track in the guide rail 2, so that the brush 1 is close to the screen surface to clean the screen, the connecting rod at the rear end of the brush 1 is installed at the front end of the hydraulic cylinder 3, and the brush 1 is driven by the hydraulic cylinder 3 to move back and forth in the guide rail 2, the rear end of the hydraulic cylinder 3 is installed on the fixed seat 4, and the brush 1 is installed on the top of the screen feed inlet through the fixed seat 4.

[0011] The working principle of the utility model is: one end of the hydraulic cylinder 3 is fixed with the brush 1, the brush 1 realizes reciprocating movement along with the extension and retraction of the hydraulic cylinder 3, when the brush 1 is consistent with the material running direction, the brush 1 is close to the screen to scrape off sundries, when the brush 1 is opposite to the material running direction, the brush 1 is away from the screen surface to avoid affecting the normal operation of the material when passing through the guide rail 2, the hydraulic cylinder 3 drives the brush 1 to reciprocate, and the automatic sundry scraping function is realized.

[0012] It is obvious for those skilled in the art that the utility model is not limited to the details of the above-mentioned exemplary embodiments, and the utility model can be realized in other specific forms without departing from the spirit or basic characteristics of the utility model. Therefore, no matter from which point, the embodiments should be regarded as exemplary, and equivalent changes in the equivalent scope are all included in the scope of the utility model.
