6. the pressing component 370 in the composite separating mechanism 300 releases the pressed roller 330, the push-pull cylinder 004 drives the turnover frame 310 to incline towards one side of the sand collecting box 140, so that one side of the opening of the roller 330 is at a low position, the turnover angle of the turnover frame 310 is preset to enable the roller 330 to form potential energy sliding towards one side of the roller limiting component 340 under the action of gravity, the sliding push disc 334 is pushed by pushing the support 356 to enable the roller 330 to slide, it needs to be pointed out that at this time, the force of the roller 330 pushing the support 356 to push the roller 330 to slide is smaller than the force of the roller 330 overcoming the compression of the return spring 335, so that the roller 330 slides and the cover 332 cannot be opened, when the retainer ring 336 sliding onto the roller 330 abuts against the boss in the roller limiting component 340, and after the pushing support 356 in the boosting component 350 pushes further, the sliding of the roller 330 already abuts against, at this time, the return spring 335 is compressed by the pushing force, the barrel cover 332 slides outwards under the sliding of the sliding rod 333 and the sliding push tray 334, that is, is correspondingly opened, so that the barrel opening of the barrel 330 is closer to the sand collection box 140, that is, the sand in the barrel 330 cannot fall outside the sand collection box 140, after pouring is completed, the pushing bracket 356 is pushed to retreat, the barrel cover 332 is correspondingly closed under the action of the return spring 335, the push-pull cylinder 004 drives the turnover frame 310 to return to the initial position, because the turnover frame 310 has a certain inclination initially, the barrel 330 can slide back to the initial position by self weight, that is, the barrel cover slides until the sliding push tray 334 abuts against the pushing bracket 356, the pressing assembly 370 is executed to press the barrel 330, the vibration screening mechanism 200 returns to the initial position, and a cleaning and separation process is completed.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
