The pressing block 88 is a circular block, the axis of the circular block coincides with the axis of the upper screen cover 6, and the upper surface of the pressing block 88 is fixed together with the lower ends of the three fixing rods 87. When the pressing component 8 is used for pressing the upper screen cover 6, a worker only needs to tightly hold the operating plate 82 and screw the threaded rod 81 downwards, the lower end of the threaded rod 81 is abutted to the pressing block 88 and continues to screw the threaded rod 81 downwards, the pressing block 88 moves downwards along with downward movement of the threaded rod 81 until the pressing block 88 stops screwing the threaded rod 81 when the bottom surface of the pressing block 88 is abutted to the upper surface of the upper screen cover 6, at the moment, the positions of the upper screen cover 6 and the filter screen 5 are fixed, the condition that the upper screen cover 6 and the filter screen 5 drop in the vibration screening process is avoided, and smooth proceeding of the vibration screening process is guaranteed. When needing to take off upper screen cover 6, the staff only need to grip operation panel 82 and upwards twist threaded rod 81 for threaded rod 81 lower extreme is kept away from compact heap 88, and at this moment, threaded rod 81 disappears to compact heap 88's compressing action, and sliding plate 84 is along sleeve 83 inside wall upward movement under spring 85's spring action, and under the effect of dead lever 87, compact heap 88 is along with sliding plate 84 upward movement and keep away from upper screen cover 6, with this the staff take off upper screen cover 6 of being convenient for.

As shown in fig. 2 and 4, the filter screen 5 is provided with a limiting assembly 9, and the limiting assembly 9 includes a first groove 91, a second groove 92 and a limiting plate 93. First recess 91 is round platform shape, and its axis and compact heap 88's axis coincidence, and the diameter of first recess 91 top surface circle is less than the diameter of first recess 91 bottom surface circle. The second groove 92 is cylindrical, the axis of the second groove is also overlapped with the axis of the pressing block 88, the first groove 91 and the second groove 92 are sequentially arranged on the bottom surface of the pressing block 88 from bottom to top, and the second groove 92 is communicated with the first groove 91. The limiting plate 93 is in a circular plate shape, the axis of the limiting plate 93 coincides with the axis of the pressing block 88, the bottom surface of the limiting plate 93 is fixed to the upper surface of the upper screen cover 6, and the limiting plate 93 is in clamping fit with the second groove 92. When the use compresses tightly subassembly 8 and compresses tightly upper screen cover 6, limiting plate 93 passes and inserts in the second recess 92 behind the first recess 91, and the lateral wall of limiting plate 93 and the inside wall laminating of second recess 92 to upper screen cover 6 is restricted in the ascending motion of horizontal direction, has avoided upper screen cover 6 and filter sieve 5 to take place the condition emergence of skew on the horizontal direction.

The implementation principle of the embodiment is as follows: before carrying out vibratory screening, the staff only needs to place a plurality of filter sieves 5 on placing the dish 2 by supreme down in proper order, closes upper screen cover 6 afterwards, adjusts the subassembly 8 that compresses tightly on the circular slab 71 simultaneously for compress tightly subassembly 8 with upper screen cover 6 compress tightly downwards can, with this firmly spacing upper screen cover 6, thereby make and lead to screen cover and filter sieve 5 remain stable at the vibrating screen vibratory screening in-process, avoided the condition that screen cover and filter sieve 5 dropped when the screening to take place.

In this scheme, for avoiding upper screen cover 6 and filter sieve 5 the condition of position deviation takes place at shale shaker vibrations screening in-process, the staff only needs to grip operation panel 82 and twist threaded rod 81 downwards, make threaded rod 81 lower extreme and compact heap 88 butt, continue to twist threaded rod 81 downwards simultaneously, compact heap 88 downstream under the impetus of threaded rod 81, stop twisting threaded rod 81 when compact heap 88 bottom surface offsets tightly with the upper surface of upper screen cover 6 until, at this moment, upper screen cover 6 and filter sieve 5's position can be injectd, the condition that upper screen cover 6 and filter sieve 5 dropped in vibrations screening in-process has been avoided, thereby the smooth of vibrations screening process has been guaranteed to go on.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
