Description

Technical Field

[0002] With the rapid development of the global economy, people's demand for mineral resources is increasing. However, in the land mining areas currently discovered and mined, the resource reserves are constantly declining, and finding new mineral resources has become a top priority. Therefore, the rich mineral resources in the deep sea with huge mining potential have become a new key research target for countries around the world. The deep sea is rich in a large number of polymetallic nodules, which can effectively alleviate the problem of mineral resource shortage. In the technical exploration of deep-sea mining, the existing deep-sea mining technology research is mostly focused on the optimization and improvement of the collection efficiency of the collection head. Most researchers use the collection test platform to simulate the actual process of seabed mining, and conduct design research through the analysis of test data, but few people have conducted research on the efficiency optimization method of ore laying and collection during the working process of the experimental platform.

[0003] The material tray is a component unit of the collection test platform. It can be used to store and load ore during the operation of the collection test platform. It is widely used in various collection test platforms due to its high load-bearing capacity, long service life, corrosion resistance, moisture resistance and other characteristics. In the preparation stage before the platform test, it is necessary to manually lift the tray to adjust the height, then lay the ore on the tray and perform detailed division work to ensure that the ore is evenly distributed on the tray. After the test, it is necessary to manually collect and weigh the remaining ore particles on the tray. The whole process will take a lot of time and seriously affect the test efficiency. In addition, since some ore particles fall off the tray due to the impact of water flow during the test, it will also have a certain impact on the accuracy of the test data. Utility Model Content
