[0033] Reference Figures 1 to 4 The utility model discloses a disc screen for screening large-sized materials and small-sized materials in a mixed material. The disc screen includes a frame 100, a disc roller 200 and a material limiting member 300.

[0034] The disc roller 200 is rotatably connected to the frame 100. The disc rollers 200 are arranged in nineteen numbers. The nineteen disc rollers 200 are arranged in sequence. A sieve port 400 is provided between two adjacent disc rollers 200. The nineteen disc rollers 200 can rotate to convey the mixed material, so that the small-sized material passes through the sieve port 400 and falls into the first area s1 below the disc roller 200, and the large-sized material is conveyed to the second area s2 at the end of the stroke. The material limiting member 300 is provided on the frame 100, and the material limiting member 300 is provided below the disc roller 200 at the end along the conveying direction. The material limiting member 300 can block the large-sized material from moving toward the first area s1 due to the disc roller 200 at the end along the conveying direction.

[0035] It is understandable that when the user inverts the mixed material onto the rotating disc roller 200, the small-sized materials in the mixed material will fall into the first area s1 through the sieve 400, while the large-sized materials in the mixed material cannot pass through the sieve 400 and are further transported by the disc roller 200 to the second area s2 at the end of the stroke.

[0036] Through the above structure, the material limiting member 300 is arranged below the disc roller 200 at the end along the conveying direction, so as to block the large-sized materials moving toward the first area s1 driven by the disc roller 200 at the end along the conveying direction, thereby reducing the large-sized materials falling into the first area s1.

[0037] In some embodiments, the number of the disc rollers 200 is ten, twenty, or the like.
