[0045] The working principle of the quartz sand rolling crushing device disclosed in the present invention is as follows: the motor 306 drives the output gear 308 to rotate through the output belt 307, thereby driving the intermediate shaft 108 to rotate, the rotation of the intermediate shaft 108 drives the side bevel gear 112, the transmission wheel 111, the missing gear 109 and the intermediate gear 110 to rotate, the intermediate gear 110 drives the lower gear 107 and the lower eccentric wheel 105 to rotate, and the movable crushing plate 104 is driven to slide back and forth along the feed box 101 through the lower push rod 106, the missing gear 109 drives the outer gear 113 to rotate intermittently, and the upper wheel 115 and the upper eccentric wheel 114 are driven to rotate intermittently through the upper transmission belt 116, and the intermittent block 102 is driven to intermittently along the feed box 101 through the upper push rod 117. The quartz stone is put into the feed box 101 by reciprocating sliding. The intermittent block 102 slides back and forth so that the quartz stone intermittently falls between the fixed crushing plate 103 and the movable crushing plate 104. The movable crushing plate 104 reciprocates, and the movable crushing plate 104 and the fixed crushing plate 103 crush the quartz stone. The distance between the fixed crushing plate 103 and the movable crushing plate 104 gradually decreases from top to bottom, thereby improving the crushing efficiency of the quartz stone. After being crushed to a certain size, the quartz stone falls into the feed chamber 208 through the drop hole 118.

At the same time, the upper gear 216 drives the spur gear 222 and the transfer bevel gear 221 to rotate through the positive transmission belt 215, driving the rear bevel gear 223, the rear shaft 224 and the rear gear 225 to rotate, thereby driving the eccentric gear 227 and the eccentric wheel 226 to rotate, and driving the lifting seat 228 to continuously rise and fall along the ore washing box 201 through the eccentric column 229. After preliminary crushing, the quartz stone falls into the feed chamber 208 and enters the clean water in the ore washing box 201. The quartz stone is transported by the conveying shaft 205, and the clean water is stirred by the stirring blade shaft 218 to improve the cleaning effect. When the quartz stone enters the filter cartridge 210, the filter cartridge 210 is provided with a number of holes, which can wash away the small particles of mud and sand in the quartz stone through the water flow and discharge it through the discharge slope 231. The cleaned quartz stone then reaches the lifting seat 228, which is continuously raised and lowered to the rolling slope 305 in batches.The outer gear 113 drives the rotating rod 309 to rotate, thereby driving the outer rotating rod 310 to rotate, thereby driving the driving gear 311 to move between the fixed rack 315 and the outer rack 312, and the fixed rack 315 drives the driving gear 311 to rotate, and the driving gear 311 drives the outer rack 312 and the transmission gear 314 to slide along the extension frame 302, and the fixed rack 315 drives the transmission gear 314 to rotate, thereby driving the inner rack 313 and the rolling frame 303 to slide back and forth.
