[0002] Quartz sand is quartz particles obtained by crushing quartz stone. Quartz stone is a non-metallic mineral, a hard, wear-resistant, and chemically stable silicate mineral. Quartz sand is an important industrial mineral raw material, not a chemical dangerous good, and is widely used in industries such as glass, casting, ceramics and fireproof materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives, and filter media. During the processing of quartz sand, it needs to be sorted, and the quartz sand sorter is particularly important in quartz sand processing equipment.

[0003] At present, when processing fused quartz sand, quartz sand with a large difference in volume needs to be processed separately, but the existing feeding devices for fused quartz sand cannot classify according to the volume of quartz sand, affecting the processing effect of quartz sand. Summary of the Utility Model

With the elastic expansion and contraction of the telescopic spring, when the driving motor drives the spiral conveying roller to rotate, the overall structure vibrates. When the quartz sand passes through the screening frame, multiple screen meshes with gradually decreasing mesh sizes screen the quartz sand of different sizes, so that the screened quartz sand falls from different discharge hoppers into the external collection box below.

[0008] Preferably, the number of the bottom plates is two, and universal wheels are fixed to both ends of the bottoms of the two bottom plates.

[0009] The universal wheels provided enable the support assembly to be moved, improving the flexibility of the overall structure.

[0010] Preferably, the telescopic spring is located between the fixed plate and the connecting block, and the two pipe clamps are respectively inserted into both ends of the outer wall of the conveying cylinder.

[0012] Preferably, a driving motor is installed at one end of the conveying cylinder, and the output shaft of the driving motor is fixedly connected to one end of the spiral conveying roller.

[0013] The spiral conveying roller is driven by the driving motor to rotate, conveying the materials in the conveying cylinder.

[0014] Preferably, the other end of the spiral conveying roller is rotatably connected to a fixing frame fixed on the inner wall of the conveying cylinder, and a feed hopper is inserted and fixed at one end of the top of the conveying cylinder.

[0016] Preferably, the top of the screening frame is provided with installation openings distributed at equal distances, and the screen meshes are respectively fixed to the inner wall tops around the installation openings, and the mesh sizes of the screen meshes gradually decrease towards the direction of the driving motor.

[0017] The screening frame is inserted into the installation openings and fits against the bottom inside the conveying cylinder. The quartz sands of different sizes are screened by multiple screen meshes with gradually decreasing mesh sizes.

[0018] Preferably, an opening is provided at the bottom of the conveying cylinder, and the opening is adapted to the specification of the screening frame. Installation blocks are fixed to both bottom ends of the opening and both bottom ends of the screening frame, and insertion blocks are inserted into the installation blocks.

[0020] The beneficial effects of the present utility model are as follows:

[0021] The driving motor drives the spiral conveying roller to rotate, conveying the quartz sand in the conveying cylinder.
