    摘要： A vibratory screening device includes a frame and a screen, supported by the frame, for separating undersize and oversize material. A vibrating device, coupled to the screen includes a first output shaft with an axis of rotation that oscillates relative to the frame. The vibrating device oscillates the screen as the first output shaft is rotated. A driver includes a second output shaft with an axis of rotation that is fixed relative to the frame. The driver rotates the first output shaft. A connector mechanically couples rotational output of the first output shaft to the second output shaft. Preferably, the connector includes a first universal joint, a sliding spline shaft, and a second universal joint. The driver preferably includes an engine, a centrifugal clutch coupled to the first output shaft, a sheave, and an endless belt connecting the centrifugal clutch to the sheave.

    摘要： A sieve screen deck comprising having a frame and a sieve screen resiliently mounted to the frame so as to allow a limited amount of movement between the sieve screen and the frame. The sieve screen has flexible side walls. The screen deck also has a rapping mechanism which itself has a ram fixed at one end relative to the frame and acting at its other end on a drive shaft via a crank arm. The drive shaft extends across the sieve screen and is rotatably journalled in the respective side walls of the sieve screen. The rapping mechanism also has a rapping bar connected to the drive shaft by resilient elongate arms. The rams is actuated so as to move the rapping bar at intervals from a rest position wherein the rapping bar is spaced a short distance from the sieve screen and the sieve screen is supported by the frame to a primed position. In the latter portion, the rapping bar is spaced further away from the sieve screen and a predetermined distance above its rest position and the screen is raised relative to the frame and thereafter to release the mechanism to allow the rapping bar and the sieve screen to fall back to the rest position with such force that the rapping bar will cause the resilient arms to bend sufficiently to cause the rapping bar to strike the sieve screen.

    摘要： A screening assembly for a mobile bulk material processing apparatus is capable of adjustment of its position with respect to the base frame of the mobile bulk material processing apparatus in order to facilitate the transfer of material from the screen on to the processing unit, such as a crusher, by optimizing the height and the angle of operation of the screening assembly. The screening assembly is also capable of being folded into a compact arrangement, which is compliant to transport regulations, while also being convenient and safe for the operators. The screening assembly includes a base frame and at least two linking elements coupled at pivotable joints in such a way that when in operational position, the two linking elements are configured to adjust the height and the angle of inclination of the screen box to facilitate transfer of material from the screen to the crusher.
