Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, in particular to a machine-made sand-motherrock screening and soil-removing vibrating screen. Background Art

[0002] Artificial sand refers to sand processed by sand making machines and other ancillary equipment. The finished product is more regular and can be processed into sand of different rules and sizes according to different process requirements, which can better meet daily needs. Artificial sand requires professional equipment to produce qualified sand and gravel. Mother rock is needed for sand making, and the quality of the mother rock directly affects the quality and precision of the sand. In order to improve the quality of the mother rock, a mother rock screening and soil removal vibrating screen is needed to screen and remove soil from mother rocks of different specifications and qualities.

[0003] The vibrating screen in the prior art drives the parent rock to be filtered through the sieve plate by the vibration of the sieve plate during use. For example, the utility model patent with publication number CN213943889U discloses a vibrating screen for screening and removing soil from machine-made sand and parent rock, which includes a shell, and movable holes are opened on the relative inner walls of the shell.

[0004] During use of the above-mentioned prior art, the first screening frame is shaken by the cooperation of the motor to facilitate the first screening of the mother rock. At the same time, the second screening frame is moved by the vibration of the first vibrator to perform a second screening on the mother rock after the first screening. However, in the process of the mother rock moving on the surface of the screening frame, the screening of the mother rock is achieved only by relying on the vibration of the screening frame. The contact between the mother rock and the screening frame is not sufficient and the problem of incomplete screening may easily occur, thereby affecting the screening efficiency of the mother rock.
