Cleaning of belt conveyor is very important in coal transportation, which is mainly determined by the characteristics of coal materials. The underground coal powder has high proportion, high moisture content, high humidity and viscosity. During the operation of the belt conveyor, coal dust will be stuck on the belt surface. If the cleaning is not complete, the operation of the equipment will be affected. During the continuous transportation of underground coal, if the cohesive and compacted coal dust is drawn into the belt pulley and wrapped on the pulley and the bearing idler group, forming a cone or uneven thickness of hard blocks, resulting in changes in the diameter and shape of the pulley, it will cause belt deviation. What is more serious is that the accumulation of hard blocks to a certain extent will also cause major accidents such as belt breakage. The application of automatic belt cleaner can solve the belt deviation caused by this kind of problem and prevent serious accidents.
The working principle of the fully automatic belt cleaner of the tail drum is to use the constant pressure of the cylinder to keep the working force of the cleaning relatively constant and effectively remove the coal deposits on the drum. When the blade is worn during operation and the distance between the blade and the roller becomes larger, the hydraulic cylinder will push the blade forward automatically for clearance compensation. In actual operation, it is only necessary to set the working pressure of the hydraulic cylinder at the initial stage, and then it is unnecessary to adjust and maintain the wiper blade. The scraping blade angle can make the coal scraps swept off the drum fall automatically, so as to achieve the purpose of cleaning.
On October 30, Li Zhenbo, General Manager of Information Technology at Shandong China Coal Group and General Manager of Zhongyun Group, was invited to deliver a keynote presentation at an activity organized by the Teaching and Research Group of the Shandong Province Technical and Vocational Schools Admissions and Employment (Industry-Education Integration) Center. The event brought together 23 technical and vocational schools across the province and focused on innovative integration of artificial intelligence with technical and vocational education, sharing practical achievements from the front lines of industry and jointly exploring new approaches to cultivating versatile digital-skills professionals through school-enterprise collaboration.
Recently, the Zhongmei Zhiren AI system, independently developed by the Intelligent Research Institute of Shandong China Coal Group, has continued to evolve and improve. Drawing on core technologies including large language models (LLMs), retrieval-augmented generation (RAG), AI agent workflow orchestration, multimodal vision, and audio and video generation, it is building a dedicated end-to-end AI platform for China’s industrial and mining supplies sector. The platform uses independently controllable AI technology to support the digital transformation of domestic and international trade and foster new quality productive forces.
Recently, three sets of software independently developed by Shandong China Coal Industry & Mining Supplies Group Co., Ltd. have successfully passed the review of the National Copyright Administration and obtained the Computer Software Copyright Registration Certificates. The three certified achievements are all built-in agent modules of the China Coal Zhiren AI System, namely: China Coal Zhiqing Image Management Tool V1.0, China Coal Construction Machinery Foreign Trade Independent Website System V1.0, and China Coal Mining Machinery Foreign Trade Independent Website System V1.0. This marks the continuous expansion of the ecological layout of the China Coal Zhiren AI System and the further consolidation of self-developed technical barriers.
Shandong China Coal Mining Support Equipment Co., Ltd. was founded in the 1990s with more than 1100 employees. It now has 53 professional companies, 3 Hong Kong companies, 1 British Cayman company and 1 American company. It is a large diversified industrial group integrating intelligent equipment manufacturing, e-commerce, software research and development and intelligent logistics, which is cultivated and supported by the Ministry of industry and information technology, the Ministry of Commerce, the development and Reform Commission, Shandong Province and Jining City.
