Meanwhile, the output end of the controller 8 is also connected with a display 9, and the display 9 displays the calculated distance result so that an operator can conveniently judge the depth of the drill rod 3.
When the system is used, firstly, when the bottom of the drill rod 3 of the pile machine is flush with the ground, the system is initialized to start counting, and the depth of the drill rod 3 is calculated.
Through the technical scheme, the simple-used system for indicating the depth of the drill rod 3 of the pile machine is provided, the reflecting strips 4 on the mast 1 are used as scales, the sensors 5 are used for identifying the reflecting strips 4 and recording the number of the passing reflecting strips 4 through the controller 8, and then the depth of the downward movement of the drill rod 3 is calculated and displayed through the display 9.
The reflecting strips 4 can be made of reflecting materials commonly used in the market, and the purpose is to enable the reflecting rate of the reflecting strips 4 and the reflecting rate of the mast 1 main body part to form a large difference, so that the sensor 5 can conveniently identify and distinguish the mast 1 main body and the reflecting strips 4.

In order to avoid long-time construction in the construction site, the problem that the reflection rate is insufficient and the identification cannot be effective due to the fact that the reflection strips 4 are smeared by dust is solved. And a cleaning brush 7 is fixedly arranged on the drill rod mounting seat 2, the cleaning brush 7 is arranged right below and above the sensor 5, and the tail end of the brush hair of the cleaning brush 7 is in contact with the mast 1 to clean the reflective strip 4.

When the drill rod 3 reaches the lowest point, the sensor 5 is flush with the lowermost reflective strip 4. Since the lower reflecting strip 4 belongs to the inactive part, the lowest one of the reflecting strips 4 is the position flush with the sensor 5 when the drill rod 3 reaches the lowest point of the working range.
The depth of the drill rod 3 is assumed to be L, and the distance between the reflecting strips 4 of the reflecting groups is assumed to be L1The number of the reflecting strips 4 of the upper reflecting group is K, and the space between the reflecting strips 4 of the lower reflecting group is L2The number of light-reflecting strips 4 passed by the sensor 5 is N.
When N is less than or equal to K, L = L1N；
When N > K, L = L1K+L2（N-K）。
