Embodiment 1

[0037] Embodiment 1: A kind of recycled concrete aggregate screening device, such as figure 1 and figure 2 As shown, it includes a support frame 1 and a body. The body includes a housing 2 and is connected with a sieve body 3 in a tilted rotation in the housing 2, and a feed hopper 15 communicated with the sieve body 3 is provided on one end of the housing 2. There are sieve holes 31 evenly distributed on the sieve body 3, and a drive mechanism for driving its rotation is provided on the sieve body 3, the drive mechanism is a motor 4 and a reducer, and the housing 2 includes a top shell 21 and a bottom shell 22 , and a material leakage port 221 is opened on the upper bottom of the bottom shell 22, so that the aggregate is poured from the feed hopper 15 into the rotating sieve body 3, and the aggregate with smaller particles can fall from the sieve hole 31 and Leaks out from the leakage port 221, and the aggregate with larger particles rolls to the lowest point of the sieve b...

Embodiment 2

[0042] Embodiment 2: A kind of recycled concrete aggregate screening device, such as Figure 7 and Figure 8 As shown, the difference between it and Embodiment 1 lies in the difference of the driving member. The driving member includes a stud 8 that penetrates in the chute 61 and abuts against the mounting bar 5 . The end of the mounting bar 5 away from the stud 8 and the chute The second spring 9 is arranged between the 61 inner walls, so only the stud 8 needs to be rotated, and the mounting bar 5 is pushed to adjust the position by means of the stud 8. When the stud 8 is rotated and moved inwardly, the second spring 9 is compressed, and the stud 8 is turned over. When the post 8 moves back, the mounting strip 5 will recover under the action of the second spring 9, the structure is simple, and the threaded stud 8 also has an axial anti-reverse effect, making the adjustment of the position of the mounting strip 5 more stable.

Abstract

The invention discloses a recycled concrete aggregate screening device. According to the technical scheme, the recycled concrete aggregate screening device comprises a support frame and a machine body; the machine body includes a shell, and a screen body rotationally connected into the shell and slantly arranged; one end of the shell is connected with a feed hopper; screen holes are distributed in the screen body; the support frame is provided with a driving mechanism for driving the screen body to rotate; mounting bars are fixed in the shell; push rods corresponding to the screen holes are axially arranged; push balls with apertures larger than that of the screen holes are fixed at the end parts of the push rods; first springs for pushing the push rods to keep the push balls recessed in the screen holes are arranged between the push rods and the mounting bars; and when aggregates are blocked in one part of screen holes, the push balls are continuously recessed in all the screen holes in the rotating process of the screen body to push the aggregates blocked in the screen holes into the screen body, so that the cleaning of the aggregates blocked in the screen holes is more conveniently realized, and the screen body is kept in an excellent screening state.

Description

technical field [0001] The invention relates to a screening device, in particular to a recycled concrete aggregate screening device. Background technique [0002] Recycled concrete is a kind of concrete prepared by using waste concrete after crushing and processing to make recycled coarse aggregate and fine aggregate, and partially or completely replacing natural coarse aggregate and fine aggregate. After waste concrete is crushed, it is obtained The aggregates are recycled aggregates, which need to be screened before use. For example, the Chinese patent with the notification number CN203791183U discloses a vibratory screening device for recycled concrete aggregates that is easy to discharge, including a sieve body and a feeding device. , bracket outer frame, electric screen seat, the feeding device is located at the upper part of the whole screening device, the lower part of the feeding device is connected with the screen body, the feeding device, one side of the screen bod...
