[0002] In the mining and other heavy industrial applications, MT series mining heavy duty trucks play a vital role. These heavy-duty trucks are usually equipped with large diesel tanks to support their long-time, high-intensity operation needs. However, as mining heavy-duty truck technology continues to advance and operating environments become increasingly complex, the design and protection of diesel tank filler necks have become a key issue to ensure equipment performance and fuel safety.
[0003] In the field of mining heavy-duty trucks, the design of MT series diesel tank filler necks is crucial to ensuring the cleanliness of fuel and the safe operation of equipment. Traditional diesel tank filler neck designs usually come with dust covers, dust shields, fireproof nets, and fireproof cloth protection facilities. These facilities have played a role in protecting the diesel tank to some extent. However, as the mining environment becomes increasingly complex and the design of filler necks continues to optimize, traditional protection facilities have been unable to meet existing usage requirements. The shortcomings of these facilities have led to serious pollution of the internal environment of the diesel tank, clogging of the fuel filter, wear and tear of critical valve components, and a decline in engine performance, which has severely impacted the performance and fuel efficiency of mining heavy-duty trucks. Specifically, while dust covers and dust shields can prevent dust and sand from entering, they are easily damaged or lost in harsh mining environments, significantly reducing their dustproof effect. Fireproof nets and fireproof cloth may not be ideal in terms of fireproofing, especially when exposed to high temperatures or fire sources for extended periods, and can easily clog and affect fuel flow. Therefore, it is necessary to design a protective cover for the diesel tank filler neck of a mining heavy-duty truck to address the aforementioned issues. SUMMARY
