Example 1
A drum screening machine for household garbage, see fig. 1-4, comprising: support frame 10, screen cloth 20, screen cloth fixed ring 30, height adjusting part 40, motor, axis of rotation 60, collection fill 70, connecting rod 80. Wherein, a plurality of screen mesh fixing rings 30 are arranged on the top of the support frame 10 in parallel and at intervals, and the screen mesh 20 is sleeved on and fixed to the screen mesh fixing rings 30. The height adjusting member 40 is used to adjust the height of one end of the screen fixing ring 30 so that the screen fixing ring 30 is inclined. The output shaft of the motor is fixedly connected with the rotating shaft 60 and is used for driving the rotating shaft 60 to rotate. A plurality of connecting rods 80 are in the solid fixed ring 30 of screen cloth, and the one end of a plurality of connecting rods 80 assembles in the solid fixed ring 30 of screen cloth center and fixed connection together, and the other end is fixed with the solid fixed ring 30's of screen cloth inner wall, specifically, can set up three connecting rods that are 120 degrees angles. The rotation shaft 60 passes through the centers of the plurality of screen fixing rings 30 and is fixedly connected with the connecting rod 80, one end of the rotation shaft 60 penetrates through the support frame 10 and is movably connected with the support frame 10, and the other end of the rotation shaft is adjusted in height by the height adjusting part 40. The collection hopper 70 is disposed below the screen 20 for collecting garbage having a particle size smaller than the aperture of the screen.
