[0025] The detection mechanism 2 includes a mounting shell 21 , the left end of the top of the built-in valve cylinder 1 is fixedly connected with the mounting shell 21 , and a rubber pad 22 is adhesively connected to the bottom of the mounting shell 21 , and the rubber pad 22 is convenient for improving the measurement stability of the viscometer 23 .

[0026] A viscometer 23 is adhesively connected to the top of the rubber pad 22 , and a damping rod 24 is fixedly connected to the top right end of the mounting shell 21 , so that the damping rod 24 is convenient for mounting and fixing the scale tape 25 .

[0027] The bottom of the sliding rod in the damping rod 24 is fixedly connected with a scale tape 25. The bottom measuring tube of the viscometer 23 passes through the top left end of the built-in valve-type cylinder body 1 and is plugged and fixed inside it. The viscometer 23 is electrically connected to an external display screen. The scale tape 25 facilitates the detection of the thickness of the rubber pad 22.

[0028] The working principle of the cylinder of a built-in valve hydraulic breaker hammer according to the first embodiment is as follows:

[0029] When the viscosity of the hydraulic oil in the built-in valve type cylinder body 1 needs to be tested, the viscometer 23 is started, and the viscosity change of the hydraulic oil in the built-in valve type cylinder body 1 is monitored through the measuring tube at the bottom of the viscometer 23 to reduce the existence of filter blockage, pump failure or other potential problems.
