At the same time, it solves the problem that the piston rod of the hydraulic cylinder is repeatedly used and has a large wear, which is not conducive to continuous detection and use.

[0007] To achieve the above purpose, the utility model provides a strength detection device for processing and preparing recycled concrete, including a base. In the middle of the upper end of the base, a pressure sensor is fixedly installed. A protection mechanism is arranged at the upper end of the base. The edge of the upper end of the base is fixedly connected with a bracket. At the top of the bracket, a hydraulic cylinder is fixedly installed.

[0008] The principle of the present utility model lies in: during use, first place the concrete block to be detected on the base and above the pressure sensor. Then, rotate the adjusting rod through the knob. The adjusting rod moves through the threaded movement between it and the linkage block, so that the sliding sleeve rises and slides on the outside of the fixed sleeve. In this way, the concrete block has a protective effect during strength detection, preventing the splashing of crushed stones and protecting the on-site workers. Then, use the hydraulic cylinder to push the pressure seat downward, so as to apply pressure to the concrete block through the pressure seat, thereby detecting its structural strength. When the pressure seat rises and resets, the top pin on the pressure seat can be inserted into the hollow shell of the lubricating mechanism from the bottom and apply pressure to the sponge block in the hollow shell, thereby releasing the lubricating oil in the sponge block, and then lubricating the piston rod, thereby reducing the wear of the piston rod and being applicable to continuous detection.
