Description

Technical Field

[0001] This utility model relates to the field of waste shredding, and in particular to a waste shredding device for the construction industry. Background Technology

[0002] With the acceleration of urbanization, my country's annual construction waste production has exceeded 3 billion tons, accounting for more than 40% of the total urban solid waste. Traditional treatment methods mainly rely on landfill and open dumping, with a comprehensive utilization rate of less than 20%, leading to problems such as waste of land resources, dust pollution, and groundwater pollution. Construction waste has a complex composition (mixture rate of concrete blocks, bricks, wood, metal, plastics, etc. > 60%), and existing equipment is unable to achieve efficient sorting and resource utilization, becoming a core pain point restricting the industry's development. Existing waste crushing equipment is mostly simple jaw crushers.

[0003] Existing waste shredding equipment typically uses an eccentric wheel to rotate, causing two impact plates to compress construction waste. However, because construction waste varies in size and weight, it's inevitable that after shredding large, heavy waste, smaller, lighter waste needs to be shredded immediately. This means the distance between the two impact plates cannot be adjusted according to the different sizes of the waste, which can significantly impact the overall efficiency of the waste shredding equipment. Utility Model Content

[0004] To overcome the problem that existing waste crushing equipment requires adjusting the distance between two impact plates to ensure the uniformity of construction waste size, but often results in a significant change in the size of construction waste in a short period of time, making it difficult for the crushing equipment to adapt.

[0005] The technical solution of this utility model is: a waste crushing equipment for the construction industry, including a crushing component, a driving component movably connected to the crushing component, an adjusting component connected to the crushing component, and a separating component movably connected to the adjusting component;

[0006] The adjustment assembly includes a material drop box connected to the crushing assembly, a fixed plate connected to the material drop box, a judgment component movably connected to the fixed plate, a plurality of reset springs connected to the judgment component, and a positioning rod disposed inside the reset springs, wherein the positioning rod is connected to the material drop box.

[0007] Preferably, the judging component includes a drop plate connected to a return spring, a laser rangefinder connected to the drop plate, a timer disposed at the front end of the laser rangefinder, and a guide groove formed on the drop plate, wherein the timer is electrically connected to the laser rangefinder.

[0008] Preferably, the separation assembly includes a sealing box movably connected to the discharge box, a fixing plate connected to the sealing box, a limiting rod connected to the fixing plate, a moving assembly connected to the sealing box, and a screening assembly movably connected to the sealing box.

[0009] Preferably, the movable component includes a second electric push rod connected to the sealing box, a mounting plate connected to the second electric push rod, and a suction fan connected to the sealing box.

[0010] Preferably, the screening assembly includes a rotating plate movably connected to the sealed box and a plurality of screening fans connected to the rotating plate.

[0011] Preferably, the crushing assembly includes a housing connected to the material feeding box, a first impact plate connected to the inner wall of the housing, a connecting frame connected to the housing, a telescopic rod movably connected to the connecting frame, a fixed frame movably connected to the telescopic rod, a first electric push rod connected to the fixed frame, a push block connected to the first electric push rod, and a second impact plate connected to the push block.

[0012] Preferably, the drive assembly includes an eccentric drum movably connected to the housing, a first synchronous pulley connected to the eccentric drum, a synchronous belt movably connected to the first synchronous pulley, a second synchronous pulley movably connected to the synchronous belt, a servo motor connected to the second synchronous pulley, and a motor bracket connected to the servo motor.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model uses a drop plate to support falling construction waste and a laser rangefinder to monitor the distance between the drop plate and the drop box to determine the weight of the construction waste falling on the drop plate. A timer is used to monitor the number of times the distance between the drop plate and the drop box changes per unit time. By combining the data from both, the size of the construction waste is determined. The position between the first impact plate and the second impact plate is adjusted by driving an electric push rod.

[0015] 2. This utility model uses a suction fan installed on the sealed box to suck up the dust generated inside the material box due to crushing, so as to quickly remove the dust. At the same time, the second electric push rod can move the position of the sealed box to quickly seal the material box. In addition, the screening fan set on the rotating plate can screen the construction waste falling from the material plate, and the airflow generated by the screening fan can separate the small particles in the construction waste, thereby significantly improving the working efficiency of the entire waste crushing equipment.
