[0016] In conjunction with the accompanying drawings, the utility model includes a shell 1, a feed port 2 is provided at the top of the shell 1, a coarse material outlet 3 is provided at the bottom of the shell 1, a sieve plate 4 is installed in the shell 1, the sieve plate 4 is a cone with a large end facing downward, a vertical rotating shaft is installed at the axis of the sieve plate 4, a driving motor 5 is connected to the lower end of the rotating shaft, the driving motor 5 drives the sieve plate 4 to rotate, an involute-shaped guide plate 6 is fixed on the upper surface of the sieve plate 4, the guide plate 6 spirally extends outward to the edge of the sieve plate 4, during the rotation of the sieve plate 4, under the guidance of gravity and centrifugal force and the guide plate 6, the coarse material that cannot pass through the screen will move along the guide plate 6 to the outer edge of the sieve plate 4 until it is out of the outer end of the guide plate 6. The material slides down the sieve plate 4 and is discharged from the coarse material outlet 3 at the bottom of the shell 1; moreover, the guide plate 6 not only has the effect of pushing the material outward, but also can extend the movement distance of the material on the sieve plate 4, so as to achieve a more thorough screening effect; a funnel-shaped fine material tray 7 is installed at the bottom of the shell 1, the fine material tray 7 is coaxial with the sieve plate 4 and is located directly below the sieve plate 4, the plate opening diameter of the fine material tray 7 is smaller than the outer edge diameter of the sieve plate 4, the fine material filtered through the sieve holes of the sieve plate 4 falls into the fine material tray 7, and a fine material outlet 8 is provided at the lower end of the fine material tray 7, the fine material outlet 8 penetrates downward through the bottom surface of the shell 1 and extends out of the shell 1, so as to discharge the fine material, and the fine material tray 7 is welded and fixed to the bottom surface of the shell 1.

[0017] The bottom of the shell 1 is a slope with one side higher than the other side, and the coarse material outlet 3 is opened at the lowest position of the bottom surface of the shell 1, so that the coarse material can be automatically discharged from the coarse material outlet 3.

[0018] A plurality of horizontal and rotatable rollers 9 are evenly distributed on the circumference of the side wall of the shell 1 . The rollers 9 are supported below the edge of the sieve plate 4 to provide support for the outer edge of the sieve plate 4 and improve the stability of the sieve plate 4 .

[0019] The driving motor 5 is fixed on the fine material tray 7 via a plurality of connecting rods 10 .

[0020] The driving motor 5 is provided with a protective shell 11 to prevent materials from falling directly onto the driving motor 5 .

[0021] The taper of the sieve plate 4 is not less than 20, so as to prevent the material from sliding too quickly to the outer edge of the sieve plate 4, resulting in a short screening time and incomplete screening.

[0022] When the utility model is in use, the feed to be screened enters the shell 1 from the feed inlet 2 and falls on the central area of ​​the screen plate 4. Since the screen plate 4 is conical, the material will move toward the outer edge of the screen plate 4 along the guide plate 6 under the action of gravity, centrifugal force and the guide of the guide plate 6 during the rotation of the screen plate 4. During the movement of the material, the fine material passes through the sieve holes of the screen plate 4 and falls into the fine material tray 7 below and is discharged from the fine material outlet 8. The coarse material finally falls from the edge of the screen plate 4 to the bottom of the shell 1 and is discharged from the coarse material outlet 3. In this way, constant speed feeding can realize continuous screening operation.

[0023] The utility model realizes the screening of coarse and fine materials and automatic continuous discharging through the conical screen plate 4 and the spiral guide plate 6 and the special coarse material discharging method, thereby realizing continuous screening operation without cleaning the coarse material, thereby improving practical convenience and screening efficiency.
