Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a waste material recovery device for bridge construction. Background Art

[0002] A bridge generally refers to a structure built across rivers, lakes, and seas to enable vehicles and pedestrians to pass smoothly. To adapt to the modern high-speed development of the transportation industry, bridges are also extended to refer to buildings that cross mountain streams, poor geological conditions, or meet other transportation needs to make travel more convenient. Road engineering refers to the entire process of planning, design, construction, maintenance, and management of roads, as well as the engineering entities involved. Road and bridge construction is an important project in urban transportation construction.

[0003] For example, a Chinese patent (publication number: CN215087566U) discloses a waste recycling device for road and bridge construction in the field of construction waste recycling technology, including a crushing box body, two drive shafts are horizontally installed in the inner cavity of the crushing box body, and crushing rollers are installed on the outer walls of the two drive shafts, and the two crushing rollers are symmetrically installed in the inner cavity of the crushing box body, and a synchronization mechanism is provided at the same end of the two drive shafts. The side wall of the crushing box body opposite to the synchronization mechanism is fixed with a drive motor by bolts. The utility model can place a waste collection bucket on both sides of the guide plate. When the waste collection bucket on one side is full, the rotation of the supporting shaft is driven by rotating the switching rocker arm, thereby driving the guide plate to tilt to the other side, so that the crushed waste can be discharged into the collection bucket on the other side, avoiding the need to stop or stop the waste delivery in order to replace the collection bucket, thereby improving the efficiency of waste crushing and processing.

[0004] The above-mentioned waste recycling device for road and bridge construction still has certain shortcomings. When the waste collection bucket on one side is full, the support shaft is driven to rotate by rotating the switching rocker arm, thereby driving the guide plate to tilt to the other side, so that the crushed waste can be discharged into the collection bucket on the other side, avoiding the need to stop or stop the waste delivery before replacing the collection bucket. However, crushing the waste by only two crushing rollers will produce waste of different sizes, and it is impossible to separate waste of different sizes, affecting waste recycling. Therefore, this application proposes a waste recycling device for bridge construction to solve the above problems. Utility Model Content

[0045] The working principle of the above embodiment is:

[0046] (1) When the filter screen 213 needs to screen the waste, the first motor 203 is started.

The left first rotating rod 206 drives the left sprocket to rotate. The left sprocket drives the right sprocket and the right first rotating rod 206 to rotate together through the chain. The two first rotating rods 206 rotate at the same time, driving the turntable 209 to rotate. When the turntable 209 rotates, it drives the second rotating rod 210 to rotate together. Through the rotation of the second rotating rod 210, the fixed frame 211 and the connecting rod 212 are driven to make a straight line motion up and down. The filter screen 213 is driven to move together through the connecting rod 212, so that the filter screen 213 can screen waste of different sizes and facilitate recycling.

[0047] (2) When the waste enters the box body 1 through the feed pipe 4, the electric push rod 502 is started, and the electric push rod 502 drives the first rack 503 to move to the left. When the first rack 503 moves, it will drive the first gear 505 and the third rotating rod 504 to rotate together, and drive the second rack 506 to move to the right through the first gear 505. When the first rack 503 and the second rack 506 move, they will drive the T-shaped block to slide inside the T-shaped groove, increasing the stability of the first rack 503 and the second rack 506 when moving. When the first rack 503 and the second rack 506 move, they will drive the baffle 508 to move together through the connecting block 507, so that the two baffles 508 move relative to each other at the same time, preventing the waste from flying out when the waste is crushed.
