Problems solved by technology
However, when the crusher fails, the staff of the coal mine often add lubricating oil to remove the fault, which will lead to the failure of the crusher. It is difficult for manufacturers and coal mines to balance the accountability of crusher failures fairly

The invention discloses an apparatus for recording the state of a mine crusher. The apparatus includes an intrinsically safe explosion-proof shell arranged on the crusher, and a core processor, a data memory, a rechargeable battery and a signal transmission interface which are arranged in the shell, a liquid level switch and a temperature sensor which are arranged on a oil tank and a vibration sensor arranged on the body of the crusher conveys signals to the core digital processor, data processed by the core processor is stored in the data memory, the rechargeable battery provides power for the core processor and the data memory, and the apparatus is connected with other external devices through the signal transmission interface; and the data memory adopts a storage chip with a data encryption function, and is provided with a factory storage password. The apparatus protects the lubrication system of the crusher by recording the state of oil in the lubricating oil tank of the crusher and the vibration condition of the crusher in a timing manner, provides bases for arbitration of responsibility after faults, and also has the advantages of only reading without writing, and data encryption storage.
Description
technical field [0001] The invention relates to a device for recording the state of a mining crusher, belonging to the technical field of intelligent monitoring of mining crushers. Background technique [0002] The mining crusher is the equipment for crushing the larger coal blocks mined by the shearer. Due to the violent vibration of the crusher when it is working, and the high temperature and high humidity underground in the coal mine, once the crusher is not lubricated in time, it is prone to failure. [0003] The main monitoring objects of the crusher lubrication system are the lubricating oil level, temperature and vibration of the machine body. By monitoring the lubricating oil level of the crusher, it can be monitored whether the lubricating oil of the crusher reaches the specified oil level. The temperature of the oil can sense whether the temperature of the lubricating oil of the crusher exceeds the normal working range. However, when the crusher fails, the staff ...
