Description

Technical Field

[0001] The utility model relates to the technical field of aggregate recycling, in particular to concrete aggregate recycling equipment. Background Art

[0002] Concrete aggregate refers to the loose granular material that acts as a skeleton or filler in concrete. It is divided into coarse aggregate and fine aggregate. Coarse aggregate refers to pebbles, crushed stones, etc., and fine aggregate refers to natural sand, artificial sand, etc.

[0003] In the prior art, a Chinese patent with publication number "CN213194545U" discloses a concrete aggregate recycling and reuse equipment, which is characterized in that concrete to be classified is placed above a screening net, and then a motor is started, the start of the motor drives the rotation shaft 1 to rotate, the rotation of the rotation shaft 1 drives the rotation of a circular rotating disk, the rotation of the circular rotating disk drives the rotation of the rotation shaft 2, the rotation of the rotation shaft 2 drives the transmission rod to move forward and backward, the forward and backward movement of the transmission rod drives the fixed rod to move forward and backward, the forward and backward movement of the fixed rod drives the fixed block to move forward and backward, the forward and backward movement of the fixed block drives the screening net to move forward and backward, the forward and backward movement of the screening net drives the fixed semicircular block 1 below to move forward and backward, the forward and backward movement of the fixed semicircular block 1 drives the transmission block 1 to move forward and backward, the forward and backward movement of the transmission block 1 drives the hard spring to move forward and backward, and the forward and backward movement of the hard spring drives the transmission block 2 to move forward and backward, so that users are exempted from the screening process, the screening quality and speed are improved, and the problem that waste slag and aggregate stick together in the existing separation equipment and the separation is not very successful is solved.

[0004] However, the existing technology still has major deficiencies, such as:

[0005] When concrete aggregate needs to be recycled and reused, waste slag and aggregate need to be separated. In the solution described above, the screening of concrete aggregate is achieved by shaking the screening net, but the concrete aggregate on the screening net will shake synchronously with the screening net, and the fine aggregate in the coarse aggregate cannot pass through the screening net quickly, which will cause too much concrete aggregate to accumulate on the screening net over a long period of time.

[0029] A driving assembly is provided on the recycling box 18, and the arc frame 1 is made to swing back and forth by the driving assembly; the driving assembly includes a gear block 3 and a positioning block 4, and the number of the gear block 3 is multiple, and the positioning block 4 is fixedly installed on the side end surface of the recycling box 18, and the gear block 3 is fixedly installed on the arc frame 1, and an electric push rod 5 is fixedly installed on the positioning block 4, and a tooth plate 6 is fixedly installed on the output end of the electric push rod 5, and the tooth plate 6 is meshed with the gear block 3. A sliding groove 7 for use with the tooth plate 6 is opened on the recycling box 18, and the electric push rods 5 in a symmetrical arrangement work in the opposite way. When the extending rod in the electric push rod 5 on one side is in an extended state, the extending rod in the electric push rod 5 on the other side is in a retracted state.

[0030] In this embodiment, the concrete aggregate is filtered through the filter screen 2 on the arc frame 1, so as to separate aggregates of different volumes, and the electric push rod 5 in the driving assembly is used to drive the tooth plate 6 to move horizontally. When the tooth plate 6 moves horizontally in the sliding groove 7, the filter screen 2 on the arc frame 1 will reciprocate through the arc groove 8 through the engagement of the tooth plate 6 and the tooth block 3, which can effectively increase the separation of concrete aggregates and improve the recovery effect of the device. Embodiment 2

[0031] On the basis of the first embodiment, in order to make the filter screen 2 on the arc frame 1 more effective in filtering concrete aggregates, an anti-deposition component is used to achieve this effect. An anti-deposition component is provided inside the recovery box 18. The anti-deposition component prevents the concrete aggregates on the filter screen 2 from clogging the filter screen 2. The anti-deposition component includes a motor 9. The motor 9 is fixedly mounted on the front surface of the recovery box 18. A stirring shaft 10 is fixedly mounted on the output end of the motor 9. A stirring blade 11 is fixedly mounted on the stirring shaft 10. The stirring blade 11 is located above the filter screen 2.

[0032] In this embodiment, when the filter screen 2 on the arc frame 1 swings back and forth, the motor 9 in the anti-deposition component drives the stirring shaft 10 to rotate, and the stirring blades 11 on the stirring shaft 10 stir the concrete aggregate on the filter screen 2, so that the fine aggregate in the coarse aggregate can be separated, making it easier for the fine aggregate to pass through the filter screen 2, effectively improving the filtering effect of the filter screen 2, and also preventing the concrete aggregate from accumulating on the filter screen 2.

[0033] Working principle:

[0034] When in use, the concrete aggregates to be classified are put into the recycling box 18 through the feed port 12, and the concrete aggregates are separated by the filter screen 2 on the arc frame 1. At this time, the electric push rod 5 drives the tooth plate 6 to move horizontally. When the tooth plate 6 moves horizontally in the sliding groove 7, the filter screen 2 on the arc frame 1 will reciprocate through the arc groove 8 through the meshing of the tooth plate 6 and the tooth block 3, which can effectively increase the separation of concrete aggregates and improve the recycling effect of the device.

[0035] At the same time, the motor 9 drives the stirring blades 11 on the stirring shaft 10 to stir the concrete aggregate on the filter screen 2. The stirring blades 11 are used to separate the fine aggregate in the coarse aggregate, so that the fine aggregate can pass through the filter screen 2 more conveniently, effectively improving the filtering effect of the filter screen 2, and also preventing the concrete aggregate from accumulating on the filter screen 2.

[0036] Small-volume aggregates will be discharged through the discharge port 13, and coarse aggregates will be on the filter screen 2. The box door 16 will be opened by the positioning bolts 17, and the large-volume aggregates on the filter screen 2 will be discharged by opening the box door 16.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
