DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] like Figure 1-6 As shown, a detachable vibrating screen pressing structure includes a screen 4, a screen support frame 5 for pressing the bottom of the screen 4, screen pressing bars 3 for fixing the screen 4 and the screen support frame 5, and a wedge 2 for pressing the screen pressing bars 3; the screen 4 is located above the screen support frame 5; the screen pressing bars 3 are arranged above the screen 4 and the screen support frame 5; the wedge 2 is arranged above the screen pressing bars 3; the pressing plate body 1 is arranged above the wedge 2, and the pressing plate body 1 is fixedly connected to the vibrating screen side plate 6; the pressing plate body 1 includes a fixed plate surface 1-1, a first horizontal plate surface 1-2, a first vertical plate surface 1-3, a second horizontal plate surface 1-4, and a second vertical plate surface 1-5.

[0024] The lower surface of the wedge block 2 is matched with the upper surface of the screen bar 3, and both are inclined surfaces. As a preferred solution, the inclined surface has an inclination angle of 30° in this embodiment. The screen bar 3 includes a large screen bar 3-1 and a small screen bar 3-2; the wedge block 2 includes a first wedge block 2-1 and a second wedge block 2-2; a plurality of first wedge blocks 2-1 are arranged above the large screen bar 3-1, and a plurality of second wedge blocks 2-2 are arranged above the small screen bar 3-2, and the first wedge block 2-1 and the second wedge block 2-2 are arranged correspondingly.
