[0025] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0026] The structure of the present utility model is described in detail below with reference to the accompanying drawings.

[0027] like Figures 1 to 7 As shown, an embodiment of the present invention provides a construction waste crushing equipment, including a first rolling frame 1 and a second rolling frame 2, a conveyor 4 is fixedly installed on the upper part of the first rolling frame 1 and the second rolling frame 2, a crushing assembly 7 is provided on the lower upper part of the conveyor 4, a support frame 8 is provided at the lower part of the crushing assembly 7, and the crushing assembly is fixedly installed on the upper part of the support frame 8, the crushing assembly 7 includes a fixed frame 701, fixed cutting knife groups 705 are fixedly installed on both sides of the fixed frame 701, a movable cutting knife group 706 is rotatably installed inside the fixed frame 701, and the outer part of the movable cutting knife group 706 is rotatably connected to the inner wall of the fixed cutting knife group 705; the movable cutting knife group 706 includes a rotating shaft 7061, a square rod 7062 is fixedly connected to the outer part of the rotating shaft 7061, an arc-shaped cutting knife 7063 is sleeved on the outer part of the square rod 7062, and a square hole 7064 corresponding to the shape of the square rod 7062 is opened inside the arc-shaped cutting knife 7063.

[0028] In the aforementioned construction waste crushing equipment, the crushing assembly 7 is supported by a fixed frame 701. Fixed blade assemblies 705 are mounted on both sides of the fixed frame 701, forming a stable cutting reference surface. A movable blade assembly 706 is also flexibly mounted within the fixed frame 701. This movable blade assembly 706 closely cooperates with the inner wall of the fixed blade assembly 705, achieving efficient cutting through relative motion. The rotating shaft 7061 of the movable blade assembly 706 serves as the power source, securely connected to a square rod 7062 on the outside. The square rod 7062 is fitted with curved blades 7063. These curved blades 7063 are carefully designed with square holes 7064 that correspond exactly to the shape of the square rod 7062, ensuring a secure connection and smooth rotation. During operation, a drive mechanism rotates the rotating shaft 7061, which in turn drives the curved blades 7063 in circular motion around the rotating shaft 7061. This design enables the curved cutter 7063 to first clamp the construction waste during rotation, and then cut it off with its sharp blade. Even round waste that is difficult to bear the force can be effectively crushed, greatly improving the crushing efficiency.

[0029] Support frame 8 not only provides a stable support platform for pulverizing assembly 7 but also optimizes the overall structure of the equipment through a rational layout. Furthermore, the pulverized material naturally falls under the action of gravity, while conveyor 4 further functions to guide the pulverized material to a designated area, effectively avoiding material accumulation below pulverizing assembly 7 and maintaining a clean and efficient working environment.

[0030] In this embodiment, the fixed cutting blade assembly 705 includes a long plate 7051 and a short plate 7052. Multiple long plates 7051 and short plates 7052 are provided, and the multiple long plates 7051 and short plates 7052 are arranged in a staggered manner. The side of the curved cutting blade 7063, which is away from the rotating shaft 7061, slides in contact with the short plate 7052. The curved cutting blade 7063 slides in contact with two adjacent long plates 7051 to perform the cutting operation.

[0031] The fixed cutter assembly 705 is composed of carefully selected long plates 7051 and short plates 7052, arranged in a unique pattern of alternating long plates 7051 and short plates 7052. The curved cutter 7063 slides in contact with the short plates 7052 on the side away from the rotating shaft 7061. This design gives the curved cutter 7063 a high degree of freedom, allowing it to freely adjust its position during rotation and flexibly handle construction waste of various shapes. When the curved cutter 7063 slides into contact with the short plates 7052, its curved design effectively captures and locks the waste, ensuring stable force during the cutting process, resulting in more efficient and thorough shredding.

[0032] The sliding fit between the curved cutter 7063 and the two adjacent long plates 7051 forms the core of the cutting action. These two long plates 7051 not only provide a stable cutting path for the curved cutter 7063, but also, through their hard material and precise arrangement, ensure the accuracy and force of the cutting action. This design demonstrates remarkable advantages, particularly for flexible waste such as plastic bags. As the curved cutter 7063 rotates, it adheres closely to the surface of the long plates 7051, using its sharp blade to precisely cut the plastic bag. This effectively prevents waste from entangled in the rotating shaft 7061 and ensures the continuous and stable operation of the equipment.

[0033] In this embodiment, a mounting plate 9 is fixedly connected to one side of the support frame 8, and a motor 10 is fixedly mounted to one side of the mounting plate 9. A first rotating wheel 702 is fixedly connected to the output end of the motor 10, and the first rotating wheel 702 is connected to a second rotating wheel 704 through a transmission belt 703. The second rotating wheel 704 is fixed to one side of the rotating shaft 7061.

[0034] A motor 10 is fixedly mounted on one side of the mounting plate 9. This motor 10 serves as the core of the entire drive system. To transmit power from motor 10 to the rotating shaft 7061, the output end of motor 10 is securely connected to a first rotating wheel 702. First rotating wheel 702 is then tightly connected to a second rotating wheel 704 located on one side of the rotating shaft 7061 via a transmission belt 703. Second rotating wheel 704, the terminal end of the transmission system, is precisely fixed to one side of the rotating shaft 7061. Its design fully considers its compatibility with the transmission belt 703 and its rotational stability, ensuring that it can drive the rotating shaft 7061 to rotate smoothly and efficiently after receiving power.

[0035] In this embodiment, the conveyor 4 is bent, and a plurality of partition plates 5 are fixedly connected to the outside of the conveyor belt of the conveyor 4. Second baffles 6 are fixedly installed on both sides of the upper part of the conveyor 4, and a first baffle 3 is fixedly installed on the bottom of the conveyor 4.

[0036] To adapt to complex working environments and optimize the material transfer path, conveyor 4 is designed with a curved shape. This non-linear layout not only saves space but also cleverly guides the flow of materials, ensuring that the crushed materials move smoothly along the pre-set path. The curved design also takes into account the stability and continuity of the materials during transfer, laying a solid foundation for efficient operation.

[0037] Several partitions 5 are fixed to the outside of the conveyor belt of conveyor 4. These partitions 5 are arranged evenly and securely, creating a safe and efficient material channel. The primary function of these partitions 5 is to prevent the crushed material from falling or scattering, even on inclined conveyor paths. This design not only improves conveying efficiency but also significantly reduces the risk of material loss and environmental pollution.

[0038] In order to further ensure the stability and safety of the material during transportation, a second baffle 6 is fixedly installed on both sides of the upper part of the conveyor 4. It effectively limits the lateral movement range of the material on the conveyor belt and prevents the material from deviating from the predetermined path due to inertia or other external forces.

[0039] Considering the safety of users and the maintenance requirements of the equipment, a first baffle 3 is fixedly installed at the bottom of the conveyor 4. This effectively isolates the direct contact between the user and the high-speed running parts inside the conveyor 4, greatly reducing the risk of users being injured by accidental touch.

[0040] The working principle of this utility model:

[0041] During use, the fixed frame 701 firmly supports the entire assembly, while the fixed cutter assemblies 705 mounted on either side of the frame provide a stable cutting base. The movable cutter assembly 706 rotates flexibly, closely cooperating with the fixed cutter assembly 705. The drive mechanism rotates the rotating shaft 7061, which in turn causes the curved cutter 7063 to perform a circular motion around the rotating shaft 7061. During rotation, the curved cutter 7063 first clamps the construction waste, then uses its sharp blades to cut and sever it, effectively crushing all types of waste, including round, hard-to-bear waste. The crushed material then falls naturally and is guided by conveyor 4 to a designated area, preventing accumulation and maintaining a clean and efficient work environment.
