Description

Technical Field

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

[0002] With the development of urbanization in my country, the amount of construction waste has been increasing year by year. Construction waste, without any treatment, is transported to the suburbs or urban peripheries for simple landfill or open-air storage. This not only wastes land and resources but also pollutes the environment. Waste concrete treatment requires the use of crushing devices to break down lumps of waste concrete into concrete blocks and fine sand for recycling. High-quality crushed and screened concrete blocks and fine sand can be used for concrete recycling. Existing technology announcement number CN215087408U proposes a recycled concrete crushing and recycling device, including a shell, a coarse crushing mechanism, and a crushing mechanism. The shell has an inlet and an outlet, with the inlet located above the outlet. The coarse crushing mechanism and the crushing mechanism are arranged sequentially from top to bottom inside the shell between the inlet and outlet. The coarse crushing mechanism is used for preliminary crushing of the concrete waste, and the crushing mechanism is used to crush the preliminarily crushed concrete into recyclable fine aggregate. However, because the extrusion-type coarse crushing mechanism is intermittent, it is easy for large volumes of concrete to fall onto the crushing mechanism when the coarse crushing mechanism opens, which can easily cause the crushing mechanism to get stuck, making it difficult to inspect and maintain. In addition, if the concrete surface is relatively smooth, the coarse crushing mechanism can cause the concrete to slide during extrusion, which cannot guarantee the initial crushing effect and can easily result in the concrete still being too large. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a waste concrete crushing and recycling device that is easy to maintain, ensures the crushing quality of waste concrete blocks, improves the discharge efficiency, and is highly practical.
