[0036] During the crushing process of quartz stone, the driving motor 23 is first started, and the driving motor 23 drives the connecting shaft 22, the crushing roller 21 and the gear 26 to rotate, and then the gear 26 drives another gear 26 to rotate during the rotation, so that the two sets of gears 26 rotate in opposite directions, so that the two sets of connecting shafts 22 and the crushing roller 21 rotate in opposite directions. At this time, the quartz stone is put into the inside of the feed port 19, and the two sets of crushing rollers 21 crush the quartz stone into quartz sand during the rotation, and then the quartz sand falls to the top of the screen 16. At this time, the external water supply device is connected to the atomizing nozzle 18, and then the atomizing nozzle 18 sprays water atomization sand onto the quartz sand, and at the same time, the double-axis motor 10 is started, and the double-axis motor 10 drives the rotating rod 12 The rotating tube 14 rotates, and the rotating tube 14 drives the mounting frame 15 and the screen 16 to rotate during the rotation.

[0038] A hinge groove is provided at the top of the cylindrical slider 11, and the bottom of the hinge rod 13 is located inside the hinge groove, which is convenient for the hinge rod 13 to flip over. The guide groove 7 is made of an elliptical structure, and the cylindrical slider 11 is adapted to the guide groove 7.

[0041] Embodiment 2

[0042] See also Figure 2 and Figure 4 , further changes were made on the basis of Example 1:

[0043] The blowing mechanism 2 includes a slip ring 201, a guide groove 202, a one-way valve 203, a guide sleeve 204, an airbag 205, a guide sleeve rod 206 and a connecting tube 207. Multiple groups of connecting tubes 207 are symmetrically arranged on both sides of the top of the mounting frame 15. The top of the connecting tubes 207 is provided with an airbag 205. A slip ring 201 is arranged between the tops of the multiple groups of airbags 205. A guide groove 202 is arranged on the top of the inner side of the crushing bin 1. The slip ring 201 is located inside the guide groove 202. The top of the airbag 205 is provided with a guide sleeve 204. The bottom of the connecting tube 207 is provided with a guide sleeve rod 206.

A one-way valve 203 is arranged at the bottom of one side of the connecting tube 207 and the top of one side of the airbag 205 to limit the airflow and facilitate the suction of the airbag 205.

[0044] During the screening process, some large particles of quartz sand may be stuck in the holes of the sieve plate, and the device can use the force of the reciprocating up and down movement of the mounting frame 15 to blow air, and then use the wind force to blow the quartz sand. During the screening process, it can effectively prevent large particles of quartz sand from blocking the mesh holes of the screen 16, thereby affecting the screening of the quartz sand, and use the wind force to turn over the quartz sand, thereby improving the screening efficiency of the quartz sand to a certain extent.

[0045] During the reciprocating up and down movement of the mounting frame 15, the airbag 205 expands and contracts following the position of the mounting frame 15. When the airbag 205 expands, the one-way valve 203 at the bottom is affected by the air pressure and is in a closed device and cannot draw external air, while the outside air enters from the one-way valve 203 at the top. When the airbag 205 contracts, the one-way valve 203 is closed due to the air pressure, so that the air inside the airbag 205 is blown out from the one-way valve 203 at the bottom, and then the quartz sand is blown up by the wind force to prevent large particles of quartz sand from blocking the holes in the screen 16. At the same time, during the rotation of the mounting frame 15, the airbag 205, the guide sleeve 206, the guide sleeve 204 and the slip ring 201 rotate with it, and the slip ring 201 moves along the guide groove 202 to ensure stability during rotation.

[0050] After the quartz sand is screened for a period of time, the pump 24 can be automatically started to extract the quartz sand screened out from the crushing chamber 1, so that the large particles of quartz sand can be crushed again to avoid wasting the quartz sand. At the same time, after a period of extraction, the pump 24 can be turned off so that the pump 24 can be turned on and off intermittently, thereby effectively saving electricity and avoiding the situation where the pump 24 is continuously turned on to affect the quartz sand screening.

[0051] During the starting process of the dual-axis motor 10, the dual-axis motor 10 drives the rotating rod 12 to rotate, and the rotating rod 12 drives the parts inside the reducer 902 to rotate, and then the reducer 902 drives the first turntable 903 to rotate slowly, and the first turntable 903 drives the push rod 914 to rotate. When the push rod 914 rotates to the inside of the push rod matching groove 916, it drives the second turntable 904 to rotate. When the push rod 914 escapes from the inside of the push rod matching groove 916, the limiting clamping plate 913 just slides into the inside of the arc groove 915 to limit the second turntable 904, so as to prevent the second turntable 904 from being deflected by external force, thereby realizing the rotation work of the second turntable 904 gap. After the second pressing plate 912 on the second turntable 904 rotates to the specified position, the second pressing plate 912 squeezes the push block 905, thereby pressing the push block 905 into the outside 908 is moved to the specified position, and the pump start switch 909 is pressed, thereby turning on the pump 24. At this time, the pump 24 extracts the screened quartz sand on the top of the screen 16 through the extraction pipe 25 and the ventilation groove 17, transports it to the inside of the discharge pipe 20, and re-discharges it into the inside of the feed port 19 for re-crushing to avoid waste of quartz sand. When the arc groove 915 continues to rotate for a certain distance, the second pressure plate 912 disengages from the push block 905. At this time, the moving rod 906 resets and pushes the push block 905, the moving rod 906 and the first pressure plate 908 to move, so that the first pressure plate 908 no longer presses the pump start switch 909, and then the pump 24 is turned off, and no longer extracts quartz sand.

[0052] The push block 905 is made of a semi-arc structure. After the second pressure plate 912 moves to the specified position, the push block 905 can be pressed into the interior of the external mounting tube 910 through the arc structure. The cross-section of the limiting clamp 913 is a semicircular structure. The limiting clamp 913 is adapted to the arc groove 915, so that the limiting clamp 913 can rotate into the interior of the arc groove 915 and cooperate with the arc groove 915, thereby limiting the second turntable 904. After the push rod 914 escapes from the push rod matching groove 916, the second turntable 904 is prevented from rotating under the influence of external force.

[0053] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
