[0020] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings. In the embodiments of the present utility model, the different types of cross-sectional lines are not labeled according to national standards, nor do they specify material requirements for the components; they are used to distinguish the cross-sectional views of the components in the drawings.

[0021] Please see Figure 1-4 A rotary grading screen with easy screen replacement includes a base 1, a support platform 2 connected to the upper left end of the base 1, a geared motor 3 mounted on the top of the support platform 2, and a left rotating rod 16 connected to the output shaft of the geared motor 3 via a coupling 4. A housing 14 is mounted on the upper right end of the base 1, and a cover 10 is embedded in the top of the housing 14. A screen frame 5 is arranged near the top inside the housing 14, and two positioning posts 9 are symmetrically arranged at the bottom inside the screen frame 5. A sealing plate 6 is provided on the top of the screen frame 5, and both ends of the sealing plate 6 are connected to the top ends of the screen frame 5 by fastening bolts 7. A screen mesh 8 is arranged inside the screen frame 5. Two positioning holes 15 are symmetrically opened on both sides of the bottom of the screen 8. Two positioning posts 9 set on the screen frame 5 are inserted into the two positioning holes 15 at the bottom of the screen 8. One end of the left rotating rod 16 passes through the housing 14 and is connected to the left end of the screen frame 5. The right end of the screen frame 5 is connected to the right rotating rod 17. The right end of the right rotating rod 17 is connected to the inner wall of the housing 14 through the support seat 12. A coarse material discharge port 13 is opened on the right side wall of the housing 14. A fine material discharge port 18 is opened at the bottom of the housing 14. A filter screen 19 is set inside the housing 14 and directly below the screen frame 5. A feed inlet 11 is opened on the upper left side of the housing 14.

[0022] The diameters of the sieve frame 5, filter screen 19, and sieve screen 8 are all the same.

[0023] The feed inlet 11 is located at the upper left of the screen frame 5.

[0024] The cover 10 can be removed from the top of the housing 14.

[0025] The sieve frame 5 is set at an angle, with the left side higher than the right side.

[0026] Among them, the support platform 2 is an inverted L-shaped structure.

[0027] The working principle and usage process of this utility model are as follows: First, the feed particles to be screened are poured in from the feed inlet 11, and the reduction motor 3 is started to drive the left rotating rod 16 on the coupling 4 to rotate. The rotating left rotating rod 16 drives the screen frame 5 to rotate, thereby driving the screen 8 inside the screen frame 5 to rotate, thus screening the feed particles. Coarse feed particles that do not pass through the mesh of the screen frame 5 and the screen 8 are discharged from the coarse material outlet 13, while fine feed particles that pass through the mesh of the screen frame 5, the screen 8 and the filter screen 19 are discharged from the fine material outlet 18, thereby achieving graded screening.

[0028] When it is necessary to replace the screen 8, the cover 10 on the housing 14 is removed, and the fastening bolts 7 at both ends of the sealing plate 6 are rotated off. Then the sealing plate 6 is removed from the top of the screen frame 5, so that the top of the screen frame 5 is opened. Then the screen 8 inside the screen frame 5 is taken out for replacement, which can realize convenient replacement of the screen 8, reduce the difficulty of replacing the screen 8 later, and make it easy to use. The contents not described in detail in this instruction are the prior art known to those skilled in the art.
