The recliner 10 includes a first link 12, a second link 13 and a third link 14 which are coaxially and sequentially nested, so that the space occupied by the recliner 10 is greatly reduced. The upper end of the first connecting rod 12 is hinged with the bottom of the other end of the sieve plate 6 corresponding to the vertex angle, the internal thread at the lower end of the first connecting rod 12 is in matched connection with the left-handed external thread at the upper end of the second connecting rod 13, the right-handed internal thread at the lower end of the second connecting rod 13 is in matched connection with the external thread at the upper end of the third connecting rod 14, and the lower end of the third connecting rod 14 is hinged with the top of the corresponding spring 7. The inclination of the screening deck 6 is adjusted by rotating the second connecting rod 13 as follows: because two ends of the second connecting rod 13 are reverse threads, when the second connecting rod 13 is rotated, the first connecting rod 12 and the second connecting rod 13 simultaneously move in the same direction along the axial direction of the third connecting rod to support or retract the sieve plate 6, and meanwhile, the three connecting rods keep a straight line to form a stable triangular structure with the sieve plate 6 and the frame.

On the other hand, the recliner 10 on the left and right sides are completely symmetrical, and the second link 13 needs to be rotated synchronously during adjustment to prevent uneven force on the two sides of the screen plate 6. The pin holes on the second connecting rod 13 and the third connecting rod 14 also have a positioning function, so that the screen surface is prevented from being unevenly stressed due to small angle error. In addition, the inclination angle regulator 10 can also adopt an air cylinder or a hydraulic cylinder, and the optimization of the vibration parameters such as the inclination angle of the sieve plate 6 can also be adjusted and fastened by using the air cylinder or the hydraulic cylinder. In addition, the inclination angle regulator 10 can also adopt an air cylinder or a hydraulic cylinder, and the optimization of the vibration parameters such as the inclination angle of the sieve plate 6 can also be adjusted and fastened by using the air cylinder or the hydraulic cylinder.
