Description

Technical Field

[0001] This utility model relates to the field of construction engineering, and more specifically, to a construction waste shredder. Background Technology

[0002] In the field of construction engineering, many waste materials, such as construction waste, need to undergo crushing processes in order to achieve the goal of efficient recycling or to optimize transportation and disposal processes. For example, after waste concrete is crushed to a specific particle size standard, it can be converted and recycled, and then used to produce recycled concrete or as road base filling material. In this series of processes, the crusher, as the core processing equipment, occupies a pivotal and key position in the resource utilization system of construction waste.

[0003] A search revealed that Chinese patent CN210125435U discloses "a construction waste crusher for construction projects, belonging to the field of waste crushing and processing. The crusher includes a base, a square box fixedly connected to the upper surface of the base via a shock absorber frame, a variable-diameter cylinder fixedly connected to the lower surface of the square box, a feed hopper on the upper surface of the square box, a crushing roller on the upper inner surface of the square box, a folded guide plate and a support seat fixedly connected to the lower inner surface of the square box, a rotating rod connected to the inner surface of the support seat via a bearing, the rotating rod rotating via the bearing, and a crushing blade fixedly connected to the lower outer surface of the rotating rod. After being crushed by the crushing roller, the waste falls into the variable-diameter cylinder, where it is continuously crushed by the lower crushing mechanism, increasing the degree of crushing. The addition of a shock absorber frame provides buffering and vibration reduction during operation, reducing vibration and noise." However, the following defects still exist:

[0004] (1) In actual use, the crushing rollers equipped with this device have a fixed position layout and lack the function of adaptive adjustment to control the crushing particle size for different types of construction waste. This can easily cause the construction waste to get stuck during the crushing process, thus affecting the normal operation of the device.

[0005] (2) In actual use, the device lacks an effective protection mechanism against dust dispersion during the crushing operation. Long-term operation will not only cause dust particles to diffuse in the working environment and cause continuous pollution to the surrounding ecological environment, but also threaten the health and safety of users through inhalation.

[0006] Therefore, we have made improvements to this and proposed a construction waste shredder. Utility Model Content

The water enters the U-shaped pipe 304 and is sprayed out by the water sprayer 306 to limit the dust generated during the crushing process, thus achieving the purpose of environmental protection and worker health protection. The crushed objects are collected in the collection box 404. The hydraulic press 402 pressurizes the crushed objects to reduce the spacing between them, thereby reducing their volume and shaping them for easy transportation. The second motor 6 drives the second crushing column 8 for secondary crushing to improve the crushing quality and prevent the initially crushed particles from being too large.
