Concrete materials are composed of granular aggregate, water, and admixtures and admixtures added when necessary. They are configured in a certain proportion, uniformly stirred, vibrated, compacted and formed, and cured and hardened. It is an artificial stone. It is widely used because of its simple production process, low price, and rapid forming. Whether it is road structure, bridge or building, concrete is indispensable. The quality of concrete directly affects the safety of the building structure and has a great impact on the cost of the construction project. Therefore, the quality inspection of concrete is a more important step in the entire inspection work. For this purpose, a concrete strength detection device is needed. However, the existing concrete detection device has a poor fixing effect on the concrete sample when testing the concrete.

Then, the outer shell can be lifted up by pushing out the electric push rod, and the lever arm can be increased by extending the sliding support plate so that the first universal wheel and the second universal wheel can be kept away from the ground, so that the outer shell cannot move when cutting and sampling concrete.

The shielding protection net can be removed and cleaned later, so that the concrete blocks can be collected, and after the test is completed, the waste storage box can be pulled out and transported to the garbage disposal site, and then the side door can be opened to pour out all the concrete waste, which is convenient for the collection, transportation and dumping of the concrete blocks under test, and can prevent dust pollution caused by the test.

[0025] Compared with the prior art, the invention has the following beneficial effects: the concrete strength detection device for road construction quality detection: 1. After the concrete block is cut out or the manufactured concrete block is completed, the waste storage box only needs to be pulled out from the shell, and the concrete block can be placed on the outer surface of the support platform of the waste storage box. Then the waste storage box can be inserted into the shell so that the concrete block can be located under the lower pressure top crushing plate, which is convenient for placing the concrete block into the detection device for testing; 2. After the concrete block is placed on the support platform, the distance between the clamping plate and the contact slide plate can be adjusted by rotating the adjustment threaded rod. After the waste storage box is inserted into the shell, the contact slide plate will be pushed so that the clamping plates can approach each other and clamp the concrete block. By adjusting the clamping plates, concrete blocks of different sizes can be clamped and the concrete blocks can be fixed during detection to reduce the data deviation caused by movement during detection; 3. After the concrete blocks are tested, the broken concrete blocks will fall into the waste storage box and slide down to the side near the side door through the inclined surface of the waste storage box, so that the concrete blocks can be automatically collected and tested multiple times. At the same time, the dust generated by the broken concrete blocks can also be extracted by the exhaust fan, so that the dust can pass through the exhaust holes and be collected by the shielding protection net, so that the dust will not be scattered around during the test and cause environmental pollution. At the same time, the tested concrete blocks can be collected and stored, and the waste storage box can be conveniently taken out from the shell after the test is completed, and the concrete blocks can be effortlessly transported to the garbage collection point through the waste storage box and the second universal wheel; 4. When cutting and sampling, you only need to push the shell to the location where sampling is required, and then start the worm motor to rotate. The rotation of the worm motor drives the turbine screw to rotate together, so that the turbine screw can rotate and push the mobile platform to move along the direction of the sliding module, so that the cutting motor can drive the cutting barrel to rotate when it rotates, and cut the concrete floor as the cutting motor descends. The self-locking property of the worm motor and the turbine screw allows the cutting barrel to descend stably without bouncing. At the same time, when the shell is moved and transported, it can ensure that the moving platform, cutting motor, and cutting barrel will not fall automatically, so that the sampling can be tested immediately after the sampling is completed, and it is convenient to carry the cutting motor and cutting barrel for movement, thereby improving the convenience of use.
