[0025] The left and right sides of the front end face of the first screening frame 2 and the left and right sides of the rear end face of the second screening frame 4 are both provided with spring fixing plates 14, the lower end faces of the plurality of spring fixing plates 14 are all fixedly connected with exciting springs 15, the lower ends of the plurality of exciting springs 15 are all fixedly connected with the mounting table 1, and the front end face of the first screening frame 2 and the rear end face of the second screening frame 4 are both provided with exciting mechanisms 16.
[0026] In the embodiment, first, the stirring motor 26 is started, the rotating rod 12 is driven to rotate along with the N-shaped sliding frame 11, the stirring frame 13 is driven to rotate by the rotating rod 12, and thus the stirring effect is achieved; then, the two air cylinders 25 are started, the N-shaped sliding frame 11 is driven to reciprocate along with the sliding block 9 and the sliding groove 10 along with the extension and retraction of the two air cylinders 25, the rotating rod 12 is driven to reciprocate, the stirring frame 13 rotating at the moment is driven to reciprocate by the rotating rod 12, and thus the reciprocating movement has the stirring effect, and the first screening inclined plate 5, the second screening inclined plate 6, the third screening inclined plate 7 and the fourth screening inclined plate 8 are distributed in an inclined manner, so that the material accumulation phenomenon caused by the vibration screening of the feed is avoided, and the screening efficiency is improved.
[0027] The high-speed motor 18 in the exciting box 17 of the exciting mechanism 16 drives the eccentric weight 19 to perform centrifugal rotation, and thus the first screening frame 2 and the second screening frame 4 are driven to vibrate along with the exciting spring 15, and thus the first screening inclined plate 5, the second screening inclined plate 6, the third screening inclined plate 7 and the fourth screening inclined plate 8 are driven to vibrate, and the vibration screening effect is achieved.
[0028] As a technical optimization scheme of the utility model, the exciting mechanism 16 comprises two exciting boxes 17, the motor fixing plates 27 are installed in the interiors of the two exciting boxes 17, the high-speed motors 18 are installed on the opposite sides of the two motor fixing plates 27, and the output ends of the two high-speed motors 18 respectively penetrate through the two motor fixing plates 27 and are fixedly connected with the eccentric weights 19.
[0029] In the embodiment, the high-speed motor 18 drives the eccentric weight 19 to rotate at high speed, and thus the first screening frame 2 and the second screening frame 4 are driven to vibrate along with the exciting spring 15 due to the centrifugal rotation of the eccentric weight 19, and thus the first screening inclined plate 5, the second screening inclined plate 6, the third screening inclined plate 7 and the fourth screening inclined plate 8 are driven to vibrate, and the vibration screening effect is achieved.

[0031] In this embodiment: two different types of mixed feed are placed on the upper ends of the first screening inclined plate 5 and the third screening inclined plate 7 respectively. Since the diameter of the first mesh 20 is larger than the diameter of the second mesh 21, the first type of mixed feed is vibrated and screened by the first mesh 20 and the second mesh 21. Then, since the diameter of the third mesh 22 is different from that of the first mesh 20, and the diameter of the third mesh 22 is larger than the diameter of the fourth mesh 23, the second type of mixed feed is vibrated and screened by the third mesh 22 and the fourth mesh 23. Thus, the effect of simultaneously screening two different types of mixed feed is achieved.
[0032] As a technical optimization of this utility model, cylinder fixing plates 24 are installed between the right end of the first screening frame 2 and the partition plate 3, and between the right end of the second screening frame 4 and the partition plate 3. Cylinders 25 are installed on the right end face of the two cylinder fixing plates 24 respectively. The output ends of the two cylinders 25 pass through the two cylinder fixing plates 24 and are fixedly connected to the N-shaped sliding frame 11.
[0033] In this embodiment: two cylinders 25 drive the N-shaped sliding frame 11 to move back and forth, which in turn drives the rotating rod 12 to move back and forth, and the rotating rod 12 drives the rotating stirring frame 13 to move back and forth, thus facilitating the reciprocating movement effect for the rotation of the stirring frame 13.
[0034] As a technical optimization of this utility model, stirring motors 26 are installed on both the front and rear sides of the upper surface of the N-shaped sliding frame 11. The two stirring motors 26 pass through the N-shaped sliding frame and are fixedly connected to the two rotating rods 12 respectively.
[0035] In this embodiment: the stirring motor 26 drives the rotating rod 12 to rotate, and the rotating rod 12 drives the stirring frame 13 to rotate. Therefore, the rotation of the stirring frame 13 achieves the characteristic of improving the sieving effect.
[0036] As a technical optimization of this utility model, the upper end surface of the mounting platform 1 is provided with two through openings 28, which correspond to the first screening frame 2 and the second screening frame 4 respectively.
[0037] In this embodiment, by passing through the orifice 28, the feed that is finally screened can flow down through the orifice 28.
[0038] Working principle and usage process of this utility model:
[0039] First, the high-speed motor 18 is started, causing the eccentric counterweight 19 to rotate centrifugally. This, in turn, causes the first screening frame 2 and the second screening frame 4 to vibrate with the excitation spring 15, thus causing the first screening inclined plate 5, the second screening inclined plate 6, the third screening inclined plate 7, and the fourth screening inclined plate 8 to vibrate, achieving the effect of vibration screening. Then, two different mixed feeds are placed on the upper ends of the first screening inclined plate 5 and the third screening inclined plate 7, respectively. At the same time, the stirring motor 26 is started, causing the rotating rod 12 to rotate with the N-shaped sliding frame 11. The rotating rod 12 then drives the stirring frame 13 to rotate, thus achieving the stirring effect. Finally, the two cylinders 25 are started. As the two cylinders 25 extend and retract, the N-shaped sliding frame 11 moves back and forth with the slider 9 and the chute 10, thus driving the rotating rod. The rotating rod 12 moves back and forth, and then drives the rotating mixing frame 13 to move back and forth. Because the reciprocating motion has a mixing effect, and the first screening inclined plate 5, the second screening inclined plate 6, the third screening inclined plate 7 and the fourth screening inclined plate 8 are distributed in an inclined shape, the accumulation phenomenon during feed screening will not occur, which can improve the screening efficiency. The two different compositions of feed are screened for the first time by the first screening inclined plate 5 and the third screening inclined plate 7, and the remaining feed is screened for the second time by the second screening inclined plate 6 and the fourth screening inclined plate 8. The remaining feed that is not screened for the second time falls through the second mesh 21 and the fourth mesh 23, and then flows down through the outlet 28, so as to achieve the characteristic of simultaneously screening two different compositions of feed, thus completing the automatic screening process.
[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
