Drawings
The accompanying drawings, which are incorporated in and constitute a part of this application, are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification.
Fig. 1 is a schematic view of the overall structure of the present invention.
In the figure: 1-machine base, 2-screening tank, 21-first discharge port, 22-second discharge port, 23-third discharge port, 3-fine screen, 4-rotating shaft, 5-coarse screen, 6-feed hopper, 7-speed regulating motor and 8-collecting barrel.
Detailed Description
Referring to fig. 1, the present invention is implemented as follows: a grading sieve for feed processing comprises a machine base 1 and a cylindrical grading sieve tank 2 arranged on the machine base 1; a coarse screen 5 and a fine screen 3 which are parallel to each other are respectively arranged in the tank body of the screening tank 2 from top to bottom, and the coarse screen 5 and the fine screen 3 are obliquely arranged; a speed regulating motor 7 is obliquely arranged above a top cover of the screening tank 2, an output shaft of the speed regulating motor 7 is connected with one end of a rotating shaft 4, the other end of the rotating shaft 4 extends into a tank body of the screening tank 2 and is respectively connected with the axial centers of the coarse screen 5 and the fine screen 3, and when the rotating shaft 4 is driven by the speed regulating motor 7 to rotate, the coarse screen 5 and the fine screen 3 can rotate along with the rotating; a feed hopper 6 is arranged on one side of the top cover of the screening tank 2, which is close to the top ends of the coarse screen 5 and the fine screen 3.
Referring to fig. 1, in the present invention, a first discharge port 21 and a second discharge port 22 are respectively disposed on a side wall of a tank body of a middle screening tank 2 near bottom ends of a coarse screening mesh 5 and a fine screening mesh 3, and the first discharge port 21 and the second discharge port 22 are respectively connected to a material collecting barrel 8, so that granular feed retained on the coarse screening mesh 5 and the fine screening mesh 3 can be smoothly discharged by arranging the first discharge port 21 and the second discharge port 22; the bottom of the screening tank 2 is conical, a third discharge hole 23 is formed in the center of the bottom of the screening tank, and the conical structure is adopted to facilitate smooth discharge of feed particles; the inclined included angles of the coarse screen 5 and the fine screen 3 and the horizontal plane are 5-8 degrees, the structure is favorable for discharging the pellet feed retained on the screen smoothly, the screening speed and the screening effect of the feed can be further improved, the discharge of the pellet feed is not facilitated due to too small inclined included angles, and the particles are easily concentrated at the bottom end of the screen due to too large inclined included angles, so that the screening speed and the screening effect are influenced.
