Embodiment：
The utility model can be explained in more detail by example below, open the purpose of this utility model is intended to protect
All changes and improvements in the scope of the utility model, the utility model are not limited to the following examples；
A kind of grinding machine that can detect wear liner, including grinding mill barrel 101, pad 102 and liner plate 103, the liner plate
103 are fixed on the inwall of grinding mill barrel 101 by intelligent bolt 2, and the inner hollow of intelligent bolt 2, hollow space passes through exhausted
Edge castable 202 is by sensor probe 203, sensor assembly 204, processor module 205, wireless communication module 206 and power supply
Module 208 is sealed in inside intelligent bolt 2, and the afterbody of intelligent bolt 2 is provided with antenna 207, and the intelligent bolt 2 passes through antenna 207
Data exchange is carried out with bolt control centre.
The length on the head of the intelligent bolt 2 is equal to the thickness of liner plate 103.
The bolt control centre is connected by ethernet communication circuit with Zhong Kong operator stations, realizes human-computer exchange work(
Energy.
The bolt control centre is connected by serial communication circuit with grinding machine programmable controller.
The sensor probe 203 includes electrode 2031 and the linear resistance 2032 of setting in parallel, and the two leads to respectively
Conductor 2033 is crossed to be connected with sensor assembly 204.
The electrode 2031, linear resistance 2032 and conductor 2033 are wrapped up by insulating materials 2034.
As Figure 1-3, intelligent bolt 2 is fixed according to circumferencial direction or horizontal direction as needed when in use
On grinding mill barrel 101, its distributed quantity can determine that every grinding machine 1 can be only according to the specification of grinding machine 1 and cost consideration synthesis
Installation one, can also be installed multiple simultaneously.The difference of intelligent bolt 2 and plain bolt is the head of intelligent bolt 2 during installation
It is generally flush with new installation liner plate, and plain bolt head is depression, i.e., bolt head is less than liner plate 103, the head of intelligent bolt 2
