Description

Technical Field

[0001] The utility model relates to the field of recycled concrete, in particular to a waste concrete block regeneration device. Background Art

[0002] Recycled concrete refers to new concrete made by crushing, cleaning, and grading discarded concrete blocks, mixing them with grading in a certain proportion, partially or completely replacing natural aggregates such as sand and gravel (mainly coarse aggregate), and then adding cement, water, etc. Recycled concrete can have the following combinations of aggregates: all aggregates are recycled aggregates, coarse aggregates are recycled aggregates and fine aggregates are natural sand, coarse aggregates are natural crushed stone or pebbles, and fine aggregates are recycled aggregates. Recycled aggregates replace part of the coarse aggregate or fine aggregate. In order to facilitate subsequent recycling, the discarded concrete blocks need to be crushed.

[0003] However, the existing waste concrete block regeneration device has certain defects in actual use. Since the waste concrete blocks come from a wide range of sources, they will contain certain nails or steel bars after being discarded. If they are not processed, it will not only affect the subsequent recycling, but also easily cause damage to the crushing device, affecting the service life of the equipment. Utility Model Content

The mounting plate 2 is symmetrically welded with L-shaped plates 4 of the crushing assembly, which are located on both sides of the mounting plate 2, and the side walls of the L-shaped plate 4 close to each other are installed with clamping plates 20 through electric push rods 19, and the side walls of the clamping plates 20 are equidistantly welded with extrusion blocks 21 (whose shape is as shown in FIG. Figure 5 As shown), it is convenient to crush the discarded concrete blocks, and in order to absorb the steel bars contained in the crushed concrete blocks and recycle them separately, the mounting plate 2 is located between the L-shaped plate 4 and the feed port 7 and is provided with two sets of adjustment components, including an electric push rod 16 equidistantly installed on the mounting plate 2, and a lifting plate 5 is commonly installed at its output end, a permanent magnet 17 of the suction component is installed under the front lifting plate 5 (close to the L-shaped plate 4), a permanent magnet 2 18 is installed under the rear lifting plate 5 (close to the feed port 7), and a toggle rod 6 is equidistantly welded under the rear lifting plate 5, so that two suctions are performed, and the crushed concrete block can be toggled before the second suction to ensure the suction effect.

[0027] See also Figure 1-Figure 5 In order to ensure the crushing effect of the concrete blocks and facilitate subsequent recycling and reuse, the crushing box 1 is symmetrically installed with a rotating shaft 14 of the crushing mechanism, and crushing fins 11 are equidistantly installed on the outside.
