[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0026] refer to Figure 1-6 The shown type of eccentric shaft double vibrator wide circular vibrating screen includes a circular vibrating screen 1, and the circular vibrating screen 1 is arranged at an angle. An eccentric shaft is provided in the circular vibrating screen 1, and there are two groups of eccentric shafts, and cams are connected to both ends of the eccentric shaft. The circular vibrating screen 1 is driven by a vibrator 3, and there are two groups of vibrators 3 and they are arranged on the same side of the circular vibrating screen 1. The output end of the vibrator 3 is connected to the cam through a universal coupling. A base 2 is provided under the circular vibrating screen 1, and the vibrator 3 is installed on the base 2. The base 2 is also connected to the circular vibrating screen 1 through a spring. A material receiving box is also provided in the base 2, and the material receiving box is located under the circular vibrating screen 1.

[0027] As an implementation method in this embodiment, a guide plate 6 and a clamping plate 9 for fixing the screen frame 7 are provided in the circular vibrating screen 1, and the screen frame 7 slides between the guide plate 6 and the clamping plate 9. The guide plate 6 is also provided with a limiting mechanism 8 for limiting the screen frame 7, and the screen frame 7 is provided with a limiting groove 5 that is adapted to the position and size of the limiting mechanism 8, and the circular vibrating screen 1 is also provided with a through hole 4, which fixes the position of the screen frame 7 when it is installed in the circular vibrating screen 1.

[0028] As an implementation method in this embodiment, in order to make the screen frame 7 fixed more firmly, the limiting mechanism 8 also includes a block 81, and a groove for installing the block 81 is opened on the guide plate 6. The block 81 rotates in the groove on the guide plate 6, and the size of the block 81 is adapted to the limiting groove 5 on the screen frame 7. The block 81 is semicircular, and teeth are provided on the arc surface of the block 81. An adjustment component for adjusting the rotation angle of the block 81 is provided below the block 81.

[0029] As an implementation method in this embodiment, the adjustment assembly includes an adjustment block 82 and a fixed block 88. The adjustment block 82 is provided with a tooth groove that matches the teeth on the clamping block 81. The clamping block 81 is engaged with the adjustment block 82. The adjustment block 82 is used to adjust the rotation angle of the clamping block 81. The fixed block 88 is bolted to the bottom surface of the guide plate 6. The fixed block 88 and the side wall of the circular vibrating screen 1 are respectively provided with a through groove and a through hole that match the adjustment block 82. The through groove is located on the fixed block 88, and the through hole is located on the circular vibrating screen 1. The adjustment block 82 slides in the through groove and the through hole. One end of the adjustment block 82 is connected to a T-shaped head 84, and the other end passes through the circular vibrating screen 1 and is connected to a handle 85. The T-shaped head 84 is used to limit the maximum length of the adjusting block 82 that can be pulled out. The handle 85 makes it more convenient and quick to pull the adjusting block 82. A mounting groove 86 is provided on the adjusting block 82. A rotating stopper 87 is connected in the mounting groove 86. The rotating stopper 87 is rotatably connected to the adjusting block 82 by rotating the bolt 83. A threaded hole for installing the rotating bolt 83 is provided on the clamping block 81. The rotating stopper 87 is used to lock the position of the adjusting block 82. When the rotating stopper 87 is in a vertical state under the action of gravity, the distance between the rotating stopper 87 and the circular vibrating screen 1 is less than the distance that the adjusting block 82 moves when the clamping block 81 needs to be released from the screen frame 7.

[0030] The sieve frame 7 is fixed to the outer edge of the circular vibrating screen 1 by the tooth groove on the adjusting block 82, so that the engaging block 81 engaged therewith is rotated, so that the semicircular engaging block 81 is rotated out of the groove on the guide plate 6, so that the engaging block 81 is simultaneously located in the groove on the guide plate 6 and the limiting groove 5 on the sieve frame 7, and the engaging block 81 limits the sieve frame 7, so that the position of the sieve frame 7 is limited. At this time, the mounting groove 86 is located at the outer side of the circular vibrating screen 1, and the rotating stopper 87 in the mounting groove 86 is swung downward under the action of gravity with the rotating bolt 83 as the axis, fixing the adjusting block 82, and the adjusting block 82 can no longer drive the engaging block 81. The block 81 rotates significantly, making the fixation of the screen frame 7 more secure. Then the equipment is powered on and the vibrator 3 is started. The vibrator 3 drives the circular vibrating screen 1 to vibrate and screen. The material is put into the vibrating screen from the top and output to the material collecting equipment from the lower side of the circular vibrating screen 1 after tilting. At the same time, the finest material falls into the material collecting box below the circular vibrating screen 1. When the screen frame 7 needs to be replaced, the equipment is stopped first, and the screen frame 7 is slightly pushed upwards through the lower side of the circular vibrating screen 1, and the rotating stopper 87 on the adjusting block 82 is rotated to a horizontal state. Then, the adjusting block 82 is pushed toward the inside of the circular vibrating screen 1 by the handle 85, so that the adjusting block 82 drives the clamping block 81 to rotate, and the clamping block 81 rotates to the groove of the guide plate 6. The clamping block 81 no longer limits the screen frame 7. Then, the new screen frame 7 can be installed into the circular vibrating screen 1, and the new screen frame 7 that needs to be replaced is pushed out of the guide plate 6, and then the new screen frame 7 is fixed by the limiting mechanism 8.
