The invention relates to a large vibrating screen with a side housing structure, using for granulation grading, dehydration, desliming and medium draining of coal, comprising a screen box, an elastic holder, a motor, a motor stand, a group of vibration exciter, a coupling of the group of vibration exciter, a bearing beam, a sieve plate, a rail base of the sieve plate, a coupling, a discharge opening and a rear plate, wherein, a side plate of the screen box is a box structure side housing, the box structure side housing comprises two side plates, two end plates at the left and right side for connecting the two side plates, a top connecting plate and a bottom connecting plate, an interlayer of the two side plates is provided with a plurality of location joint pins. With the adoption of the side housing structure, a reinforced beam is needless, the barycenter of the large vibrating screen is lower, the mass of the vibrating part of the screen is reduced, the structure rigidity is reinforced, and the manufacture technical performance is good. Compared with the prior vibrating screen with the same type, the weight is reduced 40%, the height is reduced 300 to 500 millimeter, the bendingresistance ability of the side is strong, the deformation is small, the longitudinal and lateral load resistance ability is strong, the mechanical properties of the whole machine is reliable, and theapplicability is extensive.
