Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

As shown in fig. 1 and 2, the utility model provides a screening installation of concrete aggregate, screening installation include motor 4, by output shaft 5 that motor 4 driven set up along upper and lower direction, install output shaft 5 on the turning block 6, turning block 6 on fixedly connected with one be the down tube 7 of a contained angle with vertical axis, screening installation still include screening basket 10, the bottom of screening basket 10 be fixed with a loop bar 8, loop bar 8 cover establish the down tube 7 on, and with the rotatable connection of down tube 7.

The screening equipment still include a guide bar 2 that sets up along vertical direction, the lateral wall 11 of loop bar 8 on be connected with a slider 3, slider 3 install guide bar 2 on, slider 3 can follow guide bar 2 slide from top to bottom. In a preferred embodiment, the sliding block 3 is a sleeve ring sleeved on the guide rod 2, and a gap is formed between the sleeve ring and the sliding rod. The collar cooperates with the guide rod 2 to limit the movement of the top end of the loop bar 8.

In a preferred embodiment, the upper surface of the rotating block 6 is an inclined surface 61, the inclined rod 7 is fixed on the inclined surface 61, and the inclined rod 7 is perpendicular to the inclined surface 61. The intersection point of the straight line of the inclined rod 7 and the straight line of the output shaft 5 is positioned at the top end of the loop bar 8. Motor 4 drive down tube 7 rotates along a toper orbit around a vertical axis, and down tube 7 drives loop bar 8 and swings along the toper orbit, and loop bar 8 drives screening basket 10 upper and lower ascending swing, because the straight line at down tube 7 place with the crossing point of the straight line at output shaft 5 place be located the top of loop bar 8, including the cooperation of the lantern ring and guide bar 2, the swing of direction about screening basket 10 only takes place, does not take place to rock around vertical axis, makes the overall structure of equipment more stable.
