Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

In the description of the present invention, "a plurality" means two or more unless otherwise specified; the terms "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "head", "tail", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are merely for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1-3, the movable coal pit blanking mechanism according to this embodiment includes a blanking port 2 disposed between rails 1, a sieve frame 3 adapted to the blanking port 2 is hinged to the blanking port 2, a plurality of vertical sieve plates 4 are disposed on the sieve frame 3 in parallel, and a driving device 5 for driving the sieve frame 3 to rotate is disposed on the opposite side of the hinged end of the sieve frame 3;

preferably, the hinge shaft 31 of the sieve frame 3 is perpendicular to the rail 1, and the vertical sieve plate 4 is arranged perpendicular to the hinge shaft 31;

after the coal blocks are screened by the vertical sieve plate 4, large coal blocks are left on the upper part of the vertical sieve plate 4, the driving device 5 drives the sieve frame 3 to rotate upwards and lift up, the large coal blocks on the sieve frame 3 can roll down along the vertical sieve plate 4, and then the driving device 5 drives the sieve frame 3 to rotate downwards and lay flat, so that the material can be continuously screened, the operation is convenient, the labor intensity is reduced, and the efficiency is improved; the driving device 5 is an oil cylinder, the fixed end of the oil cylinder is hinged on the fixed seat, and the output end of the oil cylinder is hinged on the sieve frame 3.
