Problems solved by technology
[0002] The vibrating screen is a commonly used screening and filtering device. Its main function is to filter the scattered materials with different particle sizes, so that the large particles remain on the upper part of the filter, and the small particles can flow through the screen. The specified container, the existing vibrating screen for drilling mud cannot perform rotary screening and vibrating screening at the same time, so that the efficiency of the vibrating screen is low when screening, and when the existing mud vibrating screen collects the filtered mud , the mud is easy to adhere to the inner wall of the collection device, and long-term accumulation is likely to cause material blocking, which affects the normal discharge of mud

The invention discloses a vibrating screen for drilling mud, and relates to the technical field of mud filtering. The vibrating screen specifically comprises a machining bin, a top cover, a vibratingdevice, a screen net, a hopper, an outer ring, a compression spring, an anti-stockpiling device, a flow guiding pipe, a flow diversion pipe and a base; the top cover sleeves the top of the machining bin, and the vibrating device is arranged in the middle of an inner cavity of the machining bin; the screen net is mounted at the top end of the vibrating device, and the hopper sleeves the bottom endof the inner cavity of the machining bin; and the outer ring is arranged on the outer side of the hopper. According to the vibrating screen for the drilling mud, through an air cylinder, a sleeve is adopted to drive the screen net to vibrate in the longitudinal direction, when the air cylinder compresses a conical spring through the sleeve, the conical spring can drive the sleeve to rotate, when the air cylinder is restored, the conical spring drives the sleeve to be restored and reversely rotate, and the situation that the vibrating screen for the drilling mud cannot conduct rotating screening and vibrating screening simultaneously, and thus the efficiency of the vibrating screen during screening is low is avoided.
