[0002] Concrete needs to be tested after mixing, so that the material properties of the concrete can be known, to ensure that the used concrete can reach the predetermined standard after solidification, and to avoid the use of unqualified concrete, such as the patent application number 201811208159.7, a construction concrete The performance testing sampling device includes a fixing seat, the fixing seat is channel-shaped steel, and pin holes are arranged on the side of the fixing seat, and a mounting seat is arranged in the middle of the lower end of the fixing seat, and the outside of the mounting seat is fitted with a guide rail mounting seat, Two polished rods are fixed inside the guide rail mounting seat, and a lead screw is installed between the two polished rods. Parallel to the axis of the polished rod, the upper end of the lead screw is connected to the output shaft of the feed motor, and the feed motor is fixedly installed with the guide rail mounting base. Although it can be fixedly assembled with an external vehicle for automatic sampling, the weight of the vehicle itself is used to carry out automatic sampling. , to ensure the stability of the sampling process, but the detection performance is not comprehensive, and the phenomenon of collapse caused by unqualified concrete materials

The invention provides a concrete sampling and detecting device which comprises a device body, a mounting groove is formed in one side of the device body, a limiting groove is integrally formed in theinner wall of the mounting groove, a penetrating groove is formed in the upper end face of the device body, a pressure block is slidably connected in the penetrating groove, and a plurality of telescopic rods are symmetrically and fixedly connected to the outer wall of the pressure block. The upper end of the inner wall of the telescopic rod is fixedly connected with a spring, the other end of the spring is fixedly connected with a fixing shaft, the upper end of the pressure block is fixedly connected with a hydraulic cylinder, the upper end of the pressure block is fixedly connected with a mounting base and a gas conveying tank, the output end of the gas conveying tank is fixedly connected with a fixing base, and the lower end of the fixing base is fixedly connected with a guide pipe. The other end of the guide pipe is connected with the hydraulic cylinder, and the lower end in the device body is fixedly connected with a low-pressure block. The device has the advantages that the operation is simple and convenient, the concrete strength is detected through sampling, and whether the concrete strength meets the design requirements or not is judged, so that the strength and the quality of built buildings and roads meet the design requirements.
