Technical Field

[0001] The utility model relates to the technical field of machine-made sand screening, in particular to machine-made sand screening equipment with adjustable granulation aperture. Background Art

[0002] Artificial sand usually refers to sand made from crushed stone and gravel through sand making machines and other auxiliary equipment. The finished product is more regular and can be processed into sand of different rules and sizes according to different process requirements. It is also called crushed sand. The manufacturing process of artificial sand is to repeatedly crush the gravel and then screen it.

The rotating gear 73 cooperates with the gear ring 75 through the second linkage teeth 74, and can drive the gear ring 75 and the screening drum 2 to rotate.

[0032] In this embodiment, the screening drum 2 includes a small particle drum 21 and a large particle drum 22. The small particle drum 21 and the large particle drum 22 are installed inside the screening drum 2. The small particle drum 21 is connected to the rotating gear 73 and will rotate along with the rotating gear 73. The large particle drum 22 is connected to the driving gear 71 and will rotate along with the driving gear 71.

[0033] In this embodiment, the small particle barrel 21 includes a clamping groove 211, a first sieve groove 212, a rotating cylinder 213, a first adjustment groove 214 and a yield groove 215. The small particle barrel 21 is provided with a clamping groove 211, and the internal rotation of the clamping groove 211 is matched with the rotating cylinder 213.

[0038] When the large particle barrel 22 is rotating, the small particles of sand and gravel in the machine-made sand will fall from the second sieve slot 222 in the large particle barrel 22 into the small particle barrel 21, and the large particles of sand and gravel will be blocked by the second sieve slot 222. Then, the small particles of sand and gravel that fall into the small particle barrel 21 will be screened by the first sieve slot 212, and the smaller particles of sand and gravel will fall from the first sieve slot 212 into the screening barrel 2, thereby forming three layers of screening with different specifications. Then, the machine-made sand after screening is discharged through the discharge end of the large particle barrel 22 and the first discharge port 5 and the second discharge port 6.

[0039] By rotating the rotating cylinder 213 and the locking cylinder 223 in the interlayer of the large particle cylinder 22 and the small particle cylinder 21, the first adjustment groove 214 and the second adjustment groove 224 are rotated to be on the same center line as the first sieve groove 212 and the second sieve groove 222, so that the screening aperture of the first sieve groove 212 and the second sieve groove 222 can be adjusted.
