Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering. More specifically, the present invention relates to a device for recycling steel bar waste in construction engineering. Background Art

[0002] Construction engineering refers to the engineering entity formed by the construction of various housing buildings and their ancillary facilities and the installation of pipelines and equipment supporting them. It covers the new construction, expansion, and renovation of houses and structures and is a branch of civil engineering. It is closely related to people's production and life. During the construction process of construction engineering, a large amount of steel bar waste is often generated. The treatment of these wastes has always been an important issue. Traditional treatment methods often involve direct disposal or landfill, which not only wastes resources but also may cause environmental pollution. Therefore, the present invention proposes a device for recycling steel bar waste in construction engineering, aiming to achieve the efficient recycling and reuse of steel bar waste to reduce resource waste and environmental pollution.

[0003] According to the patent document: CN212820153U, a device for recycling steel bar waste in construction engineering solves the problems in the prior art that randomly placed steel bar waste not only causes difficulties in cleaning at the end of the later project but also causes environmental pollution and heavy metal pollution to the surrounding soil, posing a hazard to construction workers. A device for recycling steel bar waste in construction engineering includes a box body. One side of the box body is fixedly connected to a driving motor by bolts, and a first pulley is sleeved on the output shaft of the driving motor. Two crushing rollers are provided in the inner cavity of the box body. The proposed method of recycling and screening separation effectively recycles and processes steel bar waste, which is not only highly efficient but also occupies less space after the steel bar waste is crushed, is classified and recycled without causing pollution, and is time-saving and labor-saving, with high practicality.

[0004] In some concrete slabs in construction engineering, steel bars are usually provided inside. However, when recycling waste concrete slabs, the steel bars in the concrete slabs usually need to be hammered out by construction workers using hammer-like tools. This method is not only time-consuming and laborious with low efficiency, but also during the process of hammering out the steel bars, since construction workers cannot hammer the entire concrete slab, the angle of each hammer strike is different, which is likely to damage the steel bars and affect the reuse of the steel bars. Summary of the Invention

The staff place multiple placing plate main bodies 121 with concrete slabs on the inner wall of the U-shaped transfer bin 111. The two rack bars 123 provided at the bottom of the rightmost placing plate main body 121 with a concrete slab are engaged with the outer walls of the two gears 1111. At this time, start the motor 114. The output end of the motor 114 drives the turntable 115 to rotate. While the turntable 115 rotates, it drives the crawler 116 to move. While the crawler 116 moves, it drives the second turntable 1110 to rotate. While the second turntable 1110 rotates, it drives the rotating pipe 119 to rotate. While the rotating pipe 119 rotates, it drives the rotating rod 118 to rotate. While the rotating rod 118 rotates, it drives the two rotating disks 1112 to rotate. While the two rotating disks 1112 rotate, they drive the two abutting blocks 1113 to perform circular motion. While the two abutting blocks 1113 perform circular motion, they slide on the inner walls of the two elliptical chute plates 1114. Under the action of the abutting blocks 1113, the two elliptical chute plates 1114 move up and down reciprocally through the inverted L-shaped push rod 1115. While the inverted L-shaped push rod 1115 moves up and down reciprocally, it drives the lifting plate 221 to move up and down. While the lifting plate 221 moves up and down, through the transmission of the rotating rod 222 and the V-shaped rotating rod 223, the columnar push rod 224 slides on the inner walls of the two columnar push rod guide blocks 217, and drives the U-shaped push plate connecting plate 225 and the connecting plate guide block 226 to move up and down along the outer wall of the columnar vertical rod 218, thereby driving the crushing plate U-shaped push plate 219 and the crushing plate 2110 to perform up and down reciprocating motion, and perform crushing treatment on the concrete slab placed on the crushing frame bottom plate 211. At the same time, when the rotating pipe 119 rotates, it drives the two gears 1111 to rotate. While the two gears 1111 rotate, they drive the two rack bars 123 at the bottom of the rightmost placing plate main body 121 engaged with them to move. While the rack bar 123 moves, it drives the placing plate main body 121 to slide to the right on the inner wall of the U-shaped transfer bin 111. When the rightmost placing plate main body 121 slides to the right side of the U-shaped transfer bin 111, at this time, the staff can place another placing plate main body 121 with a concrete slab on the leftmost side of the U-shaped transfer bin 111 and push it to the right so that the concrete slab placing plate main body 121 on the other side is engaged with the two gears 1111, and repeat the above operation. After the crushing plate 2110 performs crushing treatment on the concrete slab, then the staff can clean the crushed concrete blocks and collect the dropped steel bars, so as to complete the purpose of recycling the steel bars in the concrete slab.

[0022] Working principle of the present invention: When it is necessary to recycle the steel bars in the concrete slab, first place the concrete slab on the inner wall of the placing plate main body 121. The staff place multiple placing plate main bodies 121 with concrete slabs on the inner wall of the U-shaped transmission bin 111. The two rack bars 123 provided at the bottom of the rightmost placing plate main body 121 with a concrete slab are engaged with the outer walls of the two gears 1111. At this time, start the motor 114, and the output end of the motor 114 drives the turntable 115 to rotate. While the turntable 115 rotates, it drives the crawler 116 to move. While the crawler 116 moves, it drives the second turntable 1110 to rotate. While the second turntable 1110 rotates, it drives the rotating pipe 119 to rotate. While the rotating pipe 119 rotates, it drives the rotating rod 118 to rotate. While the rotating rod 118 rotates, it drives the two rotating disks 1112 to rotate. While the two rotating disks 1112 rotate, they drive the two abutting blocks 1113 to perform circular motion. While the two abutting blocks 1113 perform circular motion, they slide on the inner walls of the two elliptical chute plates 1114. Under the action of the abutting blocks 1113, the two elliptical chute plates 1114 move up and down reciprocally through the inverted L-shaped push rod 1115. While the inverted L-shaped push rod 1115 moves up and down reciprocally, it drives the lifting plate 221 to move up and down. While the lifting plate 221 moves up and down, through the transmission of the rotating rod 222 and the V-shaped rotating rod 223, the columnar push rod 224 slides on the inner walls of the two columnar push rod guide blocks 217, and drives the U-shaped push plate connecting plate 225 and the connecting plate guide block 226 to move up and down along the outer wall of the columnar vertical rod 218, thereby driving the crushing plate U-shaped push plate 219 and the crushing plate 2110 to perform up and down reciprocating motion to crush the concrete slab placed on the crushing frame bottom plate 211. At the same time, when the rotating pipe 119 rotates, it drives the two gears 1111 to rotate. While the two gears 1111 rotate, they drive the two rack bars 123 at the bottom of the rightmost placing plate main body 121 engaged with them to move. While the rack bars 123 move, they drive the placing plate main body 121 to slide to the right on the inner wall of the U-shaped transmission bin 111. When the rightmost placing plate main body 121 slides to the right side of the U-shaped transmission bin 111, at this time, the staff can place another placing plate main body 121 with a concrete slab on the leftmost side of the U-shaped transmission bin 111 and push it to the right so that the concrete slab placing plate main body 121 on the other side is engaged with the two gears 1111, and repeat the above operation. After the crushing plate 2110 crushes the concrete slab, then the staff can clean the crushed concrete blocks and collect the dropped steel bars.
