[0043] Example 2:

[0044] The present application provides a kind of premix feed screening device of anti-adhesion, please refer to Figures 1-8 Wherein, same or corresponding parts in example 1 are marked with corresponding figure marks in example 1, for the sake of simplicity, only the difference points of example 1 are described below: a pair of speed reduction mechanisms 6 are installed on the inner front end and lower end of the screening cavity 3, the speed reduction mechanism 6 includes a rotating column 601 rotatably connected to the inner end of the shell 1, a speed reduction pressing plate 602 corresponding to the lower bottom plate 502 is fixedly connected to the inner end of the rotating column 601, the speed reduction pressing plate 602 on the rear side and the upper pressing plate 506 are all magnetic, and the speed reduction pressing plate 602 and the upper pressing plate 506 are adsorbed, to prevent the weight of the humid feed from being insufficient to drive the humidity screening mechanism 5 as a whole to continue to rotate, the rear end of the speed reduction pressing plate 602 is fixedly connected with a push bent rod 603, the outer end of the push bent rod 603 is slidably connected with a speed control cylinder 604 fixedly connected with the inner end of the shell 1, and a homing spring 605 is installed between the inner end of the speed control cylinder 604 and the outer end of the push bent rod 603.

[0045] Please refer toFigure 8 The inside outer end of the speed control cylinder 604 is provided with a communication cavity 606 connected with the inner end, and the communication cavity 606 and the inside of the speed control cylinder 604 are filled with hydraulic oil, which can delay the rotation of the rotating column 601 and the speed control pressure plate 602. The included angle between the center of the speed control pressure plate 602 and the center of the main control shaft 501 is 45°, and the central axis of the speed control pressure plate 602 on the front side forms an included angle of 45° with the horizontal plane, which can make the speed control pressure plate 602 accurately abut the lower bottom plate 502 and the upper pressure plate 506.

[0046] Please refer to Figures 1-10 The inside outer end of the speed control cylinder 604 is provided with a communication cavity 606 connected with the inner end, and the communication cavity 606 and the inside of the speed control cylinder 604 are filled with hydraulic oil, which can delay the rotation of the rotating column 601 and the speed control pressure plate 602. The included angle between the center of the speed control pressure plate 602 and the center of the main control shaft 501 is 45°, and the central axis of the speed control pressure plate 602 on the front side forms an included angle of 45° with the horizontal plane, which can make the speed control pressure plate 602 accurately abut the lower bottom plate 502 and the upper pressure plate 506.

[0047] Please refer to Figures 1-10 When the premix feed needs to be screened, the operator pours a certain amount of premix feed into the screening cavity 3 through the upper end of the screening cavity 3, and the upper pressure plate 506 is pressed to move downward, and the elastic film 507 is extruded by the protruding block 504 to form a certain curvature, which improves the adhesion between the wet feed and the elastic film 507.

Then, under the adsorption of the wet feed and the upper pressure plate 506 and the speed control pressure plate 602, the humidity screening mechanism 5 continues to rotate. When the lower bottom plate 502 and the upper pressure plate 506 are in a vertical state, the upper pressure plate 506 loses the pressure and returns to its original position.
