[0030] like Figures 1 to 3 As shown, the embodiment of the utility model provides a high-efficiency vibrating screening machine for quartz sand ore, comprising a frame 1, a drop hopper 2, a blower 3, a combined drive mechanism 4, a crankshaft connecting rod assembly 5, a vibrating screen 6 and a floating connecting arm 7; the vibrating screen 6 is arranged at the bottom of the frame 1, and the vibrating screen 6 is connected to the frame 1 through a plurality of floating connecting arms 7, the vibrating screen 6 can reciprocate in the vertical direction relative to the frame 1, the drop hopper 2 is arranged at the top of the frame 1, and the drop hopper 2 is used to transport quartz sand to the On the vibrating screen 6, the blower 3 is arranged at the side end of the frame 1, and the air outlet 30 of the blower 3 is arranged between the drop hopper 2 and the vibrating screen 6. The blower 3 is used to blow air to the falling quartz sand; when the quartz sand falls from the drop hopper 2 to the vibrating screen 6, the blower 3 can blow out air outward and act on the falling quartz sand to remove impurities or fine dust particles to prevent them from adhering to the quartz sand, thereby improving the screening purity of the quartz sand, and the falling quartz sand can be screened by particle size through the vibrating screen 6.

[0031] like Figure 2 and Figure 3As shown, the combined drive mechanism 4 includes a driving motor 41, a driving pulley 42, a first driven pulley 43, a second driven pulley 44 and a transmission belt 45. The driving motor 41 is arranged on the frame 1, and the output shaft of the driving motor 41 is connected to the driving pulley 42, the first driven pulley 43 is connected to the air blower 3, the second driven pulley 44 is connected to one end of the crankshaft connecting rod assembly 5, and the other end of the crankshaft connecting rod assembly 5 is connected to the bottom of the vibrating screen 6. The driving pulley 42, the first driven pulley 43 and the second driven pulley 44 are connected by the transmission belt 45. With this arrangement, the air blower 3 and the vibrating screen 6 can be driven simultaneously by one driving motor 41 to operate, which not only reduces the overall complexity of the equipment and reduces energy consumption, but also realizes the coordinated operation of the air blower 3 and the vibrating screen 6, avoiding the impact of asynchronous operation on the screening effect.

[0032] like Figure 1 and Figure 2 As shown, the blower 3 further includes a housing 31 and fan blades 32. The housing 31 has an interior containing a chamber 300. The fan blades 32 are located within the chamber 300 and are connected to the first driven pulley 43 via a rotating shaft. An air outlet 30 communicating with the chamber 300 is provided at a side end of the housing 31. The housing 31 encloses the fan blades 32 within the interior containing chamber 300, thereby protecting the fan blades 32 and preventing them from being disturbed by external materials or impurities during high-speed rotation.

This arrangement allows qualified quartz sand particles to fall into the receiving plate 62 after being screened, while large particles of quartz sand that have not passed the screening are discharged through the discharge trough 63, thereby avoiding the mixing of large and small particles of quartz sand and improving the screening quality. It should be noted that a discharge port is provided at the end of the receiving plate 62 to achieve the smooth discharge of quartz sand.

[0036] like Figure 3 As shown, further, the floating connecting arm 7 includes a swing arm 70, a first connecting rod 71 and a second connecting rod 72.
