The invention relates to the technical field of vibration sieves, in particular to a double-layer drilling fluid vibration sieve. The double-layer drilling fluid vibration sieve comprises a sieve box,a damping device is fixedly connected with the lower side of a first connecting seat and comprises a supporting column and a first damping base, a second connecting seat is fixedly arranged on the lower right side of the sieve box, a lifting damping device is fixedly connected with the lower side of the second connecting seat and comprises a hydraulic cylinder and a second damping device, a shock-excitation beam is fixedly connected with the inner wall of a vibration source conducting plate, a first vibration motor is fixedly connected with the upper side of a vibration motor mounting seat, asecond vibration motor is fixedly connected with the left side of the vibration motor mounting seat, and lower layer sieve nets are fixedly connected with the lower side of an upper layer sieve net and the inner wall of the sieve box respectively. By means of the double-layer drilling fluid vibration sieve, secondary vibration and screen can be conducted on the drilling fluid, so that the large-particle solid phase and small-size solid phase in the drilling fluid are screened separately, the efficiency of the screening purification can be improved, and the use performance of the drilling fluid can be effectively improved.
