Description

Technical Field

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

[0002] As is well known, construction waste is the waste generated in construction projects, encompassing various waste materials generated during the construction of houses, roads and bridges, etc. It mainly includes waste such as bricks, tiles and concrete blocks generated when demolishing old buildings. Crushing devices can crush the impurities in construction waste to facilitate subsequent classification and recycling.

[0003] However, traditional construction waste crushing equipment usually adopts a single crushing method, such as simple compression or knocking, which makes it difficult to control the crushing force and particle size, and cannot be crushed uniformly. Therefore, technical improvements are urgently needed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a construction waste crushing device. When in use, the device uses multiple sets of cylinders to drive the hammer to perform initial crushing of the waste. Subsequently, a servo motor is activated to drive a rotating rod on one side to rotate, which in turn drives a gear on the other side to rotate in the opposite direction, thereby performing secondary crushing of the crushed waste and making the particle size of the waste more uniform.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A construction waste crushing device includes a support frame. A flow rack is fixedly connected to one side of the upper surface of the support frame. Two mounting boxes are fixedly connected to the top surface of the flow rack. Multiple cylinders are fixedly connected to the top surface of each mounting box. A pressure hammer is fixedly connected to the output end of each cylinder. A crushing frame is fixedly connected to the other side of the upper surface of the support frame. Rotating rods are rotatably connected to both sides of the inner wall of the crushing frame. Each pair of rotating rods is meshed with gears. Multiple crushing blades are fixedly connected to the outer wall of each rotating rod.

[0007] Compared with existing construction waste crushing devices, this construction waste crushing device, when in use, can perform primary crushing of waste by starting multiple sets of cylinders to drive the hammer. Then, by starting the servo motor to drive the rotating rod on one side to rotate, it drives the gear on one side to rotate, which in turn drives the rotating rod on the other side to rotate in the opposite direction, thus performing secondary crushing of the crushed waste and making the particle size of the waste more uniform.

[0008] Furthermore, a PLC control panel is provided on the lower part of one side of the front outer wall of the support frame;

[0009] The above technical solution allows for easy control of the cylinder and servo motor by electrically connecting them to the PLC control panel.

[0010] Furthermore, a groove is provided on the other side of the lower surface of the support frame, and the upper end of the groove is connected through the crushing frame.

[0011] The above technical solution facilitates the discharge of waste residue through the trough.

[0012] Furthermore, an inlet is provided on one side of the upper surface of the circulation rack;

[0013] The above technical solution facilitates the entry of waste residue through import.

[0014] Furthermore, an outlet is provided on the outer wall of the other side of the circulation rack;

[0015] The above technical solution allows for the easy discharge of waste residue from the initial crushing via an outlet.

[0016] Furthermore, a feeding rack is fixedly connected to the upper end of the crushing rack;

[0017] The above technical solution facilitates the entry of the initial crushed waste residue through the feeding rack.

[0018] Furthermore, a protective shell is fixedly connected to the outer wall of the front end of the crushing frame, the front end of each rotating rod penetrates through the crushing frame to the outside of the crushing frame, and a servo motor is fixedly connected to the front end of the inner wall of the protective shell. The output end of the servo motor is fixedly connected to the outer wall of the front end of one rotating rod.

[0019] The above technical solution allows the servo motor to drive the rotating rod on one side to rotate while simultaneously driving the gear on the other side to rotate.

[0020] Furthermore, multiple baffles are fixedly connected to both sides of the upper end of the inner wall of the crushing frame;

[0021] The above technical solution uses baffles to prevent waste residue from entering from both sides.

[0022] This utility model has the following beneficial effects:

[0023] 1. The present invention proposes a construction waste crushing device. Compared with existing construction waste crushing devices, when this construction waste crushing device is used, multiple sets of cylinders are started to drive the pressure hammer to perform primary crushing of the waste. Then, by starting the servo motor, one side of the rotating rod is driven to rotate, which in turn drives the gear on one side to rotate, thereby driving the other side of the rotating rod to rotate in the opposite direction, which can perform secondary crushing of the crushed waste and make the particle size of the waste more uniform.
