Screening machine

Abstract

The invention discloses a screening machine which comprises a shell. An inlet; the screen is obliquely arranged in the shell relative to the horizontal plane and comprises a plurality of screen bars; the first receiving part is used for receiving the fine materials; the second receiving part is used for receiving coarse materials; the movable device comprises a movable frame which is positioned below the screen; the multiple jacking parts are arranged on the movable frame and are arranged at intervals in the first direction; two ends of the first connecting frame rod are respectively hinged with the movable frame and the shell; the driving device is in driving connection with the first side link and is used for driving the first side link to rotate relative to the shell; the movable device is configured as follows: in an ejection state, the driving device drives the first side link to rotate relative to the shell; therefore, the materials have the moving tendency of moving upwards in the direction perpendicular to the inclined surface of the screen and the moving tendency of moving downwards in the inclined direction of the screen due to the acting force of the material ejecting parts entering the corresponding first gaps on the materials which are in contact with the screen and located on the screen.

Description

technical field [0001] The invention relates to the field of material screening machinery, in particular to a screening machine. Background technique [0002] Mineral preparation plants, coal preparation plants, coking plants and other places often have materials in narrow spaces that need to be screened. Existing screening machines require a large inclination angle for the screen (the angle needs to be greater than the material accumulation angle). Extensions are often difficult to fit into tight spaces. At the same time, large pieces of material are also easy to get stuck in the screen, resulting in reduced screening efficiency, and the screen needs to be cleaned regularly. Contents of the invention [0003] The purpose of the present invention is to provide a screening machine that can meet the requirements of a narrow space and has a good screening effect. [0004] The invention discloses a screening machine, comprising: [0005] case; [0006] The inlet is arrange...
