[0001] This utility model relates to the field of PE pipe technology, and in particular to a crushing device for recycling PE pipes. Background Technology

[0002] PE pipe, or polyethylene pipe, is a type of plastic pipe widely used in various industrial and civil fields. It is known for its excellent physical properties, outstanding chemical stability, and significant economic benefits, making it the preferred material for many engineering projects. With the widespread application of plastic products, polyethylene (PE) pipes have been used extensively in municipal water supply, drainage, gas transmission, agricultural irrigation, and other fields. However, the disposal of waste PE pipes has become an increasingly serious environmental problem. Traditional landfill and incineration methods not only waste resources but also cause serious environmental pollution. Therefore, developing efficient and environmentally friendly PE pipe recycling equipment has become the key to solving this problem.

[0003] Existing PE pipe recycling processes typically include pretreatment, crushing, washing, and granulation. Among these, the crushing stage is one of the core technologies in the entire recycling process, and its efficiency and effectiveness directly affect the quality and cost of subsequent recycling. However, in many existing devices, the feeding process of PE pipes relies on manual operation. Workers need to manually put the PE pipes one by one into the crushing equipment. This operation method is not only time-consuming and labor-intensive, increasing the labor intensity of workers, but also makes manual handling and placement more difficult for larger or longer PE pipes, which can easily lead to worker fatigue or even injury.

[0004] Therefore, it is necessary to design a crushing device for PE pipe recycling to solve the above-mentioned technical problems. Utility Model Content
