[0002] With the continuous development of my country, the demand for quartz sand in the fields of construction, chemical industry and casting is also increasing. Quartz sand is produced by crushing quartz stone. When quartz stone is crushed to form quartz sand, the interior of the quartz sand contains a large number of impurities, which affects the quality of the quartz sand and thus its performance. Therefore, after the quartz stone is crushed to form quartz sand, it is necessary to use a screening device to screen the crushed quartz sand to remove impurities and extract the quartz sand.
[0003] A fracturing quartz sand screening device, disclosed in publication CN 218854788 U, includes a hopper, a sand inlet, a screening chamber, a storage rack, a motor, a cleaning device, and a sand outlet. The bottom of the hopper is fixedly connected to the sand inlet, the bottom of the sand inlet is fixedly connected to the screening chamber, and the bottom of the screening chamber is fixedly connected to the storage rack. A motor is installed inside the storage rack. The right end of the screening chamber is fixedly connected to the cleaning device, and the right end of the screening chamber has a sand outlet. An optimized agitator is installed inside the first cavity. Powered by the motor, the agitator uses a paddle to screen the quartz sand within the screening frame. A slider and a locking block ensure thorough screening of the quartz sand, avoiding cost waste. The cleaning device is located on the right side of the screening chamber. A water pump uses a nozzle to clean the first cavity, and an electric push rod further enlarges the working area of the nozzle for enhanced cleaning.
[0004] However, the above-mentioned device still has some shortcomings in use. When screening, the quartz sand needs to be manually moved to the high hopper position and manually fed. The quartz sand is heavy, the manual labor intensity is high, the efficiency is low, it is time-consuming and laborious, and it is inconvenient to use. Utility Model Content

[0013] Compared with the prior art, this utility model provides a quartz sand screening device for fracturing, which has the following beneficial effects: In use, the quartz sand to be screened is put into the storage box. Then, the rotation of the first motor drives the winding roller to wind up the steel rope, thereby driving the connecting plate and the storage box to rise. When the storage box rises to the position of the hopper, the rotation of the second motor drives the screw to rotate, thereby driving the screw sleeve and the storage box to move, so that the storage box moves to the top of the hopper. Then, the electric push rod retracts to drive the baffle to rise, exposing the opening. Then, the rotation of the third motor of the push assembly drives the lead screw to rotate, thereby driving the lead screw sleeve and the push plate to move.

The rotation of the first motor 13 can automatically drive the connecting plate 9 and the storage box 12 to rise, without the need for manual handling.
[0022] Example 3: The difference between this example and Example 1 is that the inner side walls of the mounting bracket 5 are provided with sliding grooves 14, and the sliding grooves 14 are slidably connected with sliders 15.

Then, the rotation of the third motor 27 of the push assembly drives the lead screw 22 to rotate, thereby moving the lead screw sleeve 23 and the push plate 26. The push plate 26 pushes out the quartz sand inside the storage box 12, causing the quartz sand to fall from the opening into the hopper 4 and then onto the screening machine 2 for screening. When in use, this device can automatically drive the quartz sand to rise to the position of the hopper 4 and automatically feed it in. No manual handling is required, saving time and labor, improving screening efficiency, and reducing labor intensity.
