Machine-made sand screening equipment capable of adjusting screening granularity

The invention provides machine-made sand screening equipment capable of adjusting screening granularity, and relates to the technical field of machine-made sand screening equipment. The machine-made sand screening equipment capable of adjusting the screening granularity comprises a bottom shell, an adjusting mechanism is installed on the outer side of the bottom shell and comprises a support, a supporting block is slidably connected to the top of the support, a sealing frame is fixedly connected to the outer side of a balance wheel, and a screen is fixedly connected to the interior of the sealing frame. According to the machine-made sand screening equipment capable of adjusting the screening granularity, a telescopic wheel drives a telescopic rod to slide, the turning radius of the screen is reduced, the replacement space is reduced, meanwhile, the balance wheel drives the screen to swing to the vertical position, the external space of the screen is reduced, and after the screen is installed in place, a rolli
