Description
Technical Field
The invention relates to the related field of bridge engineering, in particular to construction waste smashing equipment for bridge engineering and a smashing method thereof.
Background
The construction waste refers to the general name of dregs, waste concrete, waste bricks and stones and other wastes produced by people in the production activities of the construction industry such as demolition, construction, decoration and repair. The construction waste can be classified into engineering residue soil, decoration waste, demolition waste, engineering slurry and the like according to the production source; the construction waste can be classified into slag, concrete blocks, broken stone blocks, broken bricks and tiles, waste mortar, slurry, asphalt blocks, waste plastics, waste metals, waste bamboo and wood and the like according to the composition. With the acceleration of industrialization and urbanization, the construction industry is rapidly developing, and along with the increase of the generated construction waste, the quantity of Chinese construction waste accounts for more than 1/3 of the total quantity of municipal waste. The site selection of most urban construction waste stacking sites is random to a great extent, construction waste stacking sites are formed nearby construction sites, and due to the fact that construction is convenient and due protective measures are lacked, the construction waste stacks collapse under the influence of external factors, and the phenomenon that roads are blocked and even other buildings are impacted is avoided. A large amount of construction waste is randomly stacked, not only occupies the land, but also pollutes the environment, and directly or indirectly influences the air quality. During the process of stacking and burying the construction waste, leachate or leachate which is sewage seeped by fermentation, leaching and scouring of rainwater and soaking of surface water and underground water can cause serious pollution to the surrounding surface water and underground water. The construction waste of bridge engineering is less than that of building engineering, but because the construction site is positioned near the water flow and is not treated, the pollution to the water flow is far greater than that of the water in the building engineering.
At present, the crushing equipment of construction waste realizes crushing through a special crusher, in order to ensure that the particle size of the crushed material is smaller than a standard value, a plurality of groups of crushing structures are usually arranged in the crusher for crushing, but the arrangement of the plurality of groups of crushing structures can increase the occupied space of the equipment; therefore, the market urgently needs to develop building rubbish smashing equipment for bridge engineering and a smashing method thereof to help people solve the existing problems.

step two: the discharging pipe (4012) discharges materials to reach a screening cavity (307) inside a first screening metal net (302) through a feeding hopper (308), output rods of second hydraulic cylinders (314) on the left side and the right side extend and contract alternately, the first screening metal net (302) shakes, a third driving motor (3031) on a swinging mechanism (303) drives a rotating disc (3032) to rotate, a rotating column (30321) connected with the rotating disc (3032) slides in a middle groove (30331) of the swinging rod (3033), the swinging rod (3033) rotates, and the first screening metal net (302) swings back and forth in the longitudinal direction as the swinging rod (3033) is connected with a side fixed disc (305) on one side of the first screening metal net (302) through a semicircular protruding block (30332);
step three: the first screening metal net (302) swings back and forth and swings back and forth, the construction waste in the first screening metal net (302) is rapidly screened, the construction waste with the aperture smaller than that of the first screening metal net (302) falls to the upper end of the first conveyor belt (201), an output shaft of the first driving motor (202) drives the first connecting roller to rotate so as to drive the first conveyor belt (201) to rotate, and the construction waste with small particle size is conveyed through the first conveyor belt (201);
step four: after the construction waste in the first screening metal net (302) is smaller than the aperture of the first screening metal net (302) is discharged, the output rod of the first hydraulic cylinder (311) is extended, the side sealing disc (310) is driven to be far away from the connecting column (301), until the discharge chute (3121) is just completely exposed, the output rod of the second hydraulic cylinder (314) on the left side is contracted, the output rod of the second hydraulic cylinder (314) on the right side is extended, the screening unit (3) inclines towards the discharge chute (3121), the construction waste in the first screening metal net (302) which is larger than the aperture of the first screening metal net (302) falls to the upper end of the second conveyor belt (203) through the discharge chute (3121), the output shaft of the second driving motor (204) drives the second connecting roller to rotate so as to drive the second conveyor belt (203) to rotate, and the second conveyor belt (203) conveys the construction waste with large aperture.
