[0002] Concrete is the most common building material nowadays. During its use, its hardness and strength are tested. Usually, a portion of the concrete is cut off and tested by applying pressure with a strength testing machine to obtain accurate data.

[0003] However, most common strength testing machines on the market have some common problems. During the use of the machine, the concrete breaks up and generates dust and concrete fragments. Common strength testing machines do not have cleaning and dust removal functions, and manual cleaning is required after use, which is time-consuming and labor-intensive. If the machine is not cleaned for a long time, it will affect the normal use of the strength testing machine, leading to problems such as inaccurate test data or parts jamming. Therefore, a concrete strength testing machine is proposed. Utility Model Content

[0015] Beneficial effects

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0017] 1. This concrete strength testing machine places the concrete block to be tested in the middle of the bearing plate. The cylinder drives the pressure rod to extend and retract, and the pressure plate applies pressure to the concrete block. The strength data is obtained through the pressure sensor. The data is transmitted back to the control box through the electrical connection between the pressure sensor and the control box. The dust generated during the process is sucked out of the testing box by the suction force generated by the fan and then filtered by two filter plates in the filter box, thus ensuring that the cleanliness inside the testing box is not damaged by dust.

[0018] 2. This concrete strength testing machine uses an electric actuator to drive a cleaning roller. The cleaning roller pushes the crushed stone on the bearing plate through the waste inlet into the storage tank along the moving limit plate. Water is then supplied through the water inlet pipe, pumped into the spray pipe ring, and then formed into water droplets through the nozzles and enters the testing tank. The adsorption force of the water droplets thoroughly cleans the inside of the testing tank. Finally, the liquid reaches the storage tank through the drain hole, and then passes through the solid-liquid separation plate in the storage tank to separate the crushed stone and liquid for storage, thereby achieving the purpose of saving labor and time costs.

[0034] Specifically, such as Figure 2As shown, after the concrete block is placed on the bearing plate 407, the device drives the pressure rod 402 to move through the cylinder 401, and then applies pressure to the concrete block through the pressure plate 404.

[0035] When implementing this procedure, please follow these steps:

[0036] 1) First, place the concrete block onto the support plate 407 inside the testing box 1;

[0040] In summary, this concrete strength testing machine uses a cylinder 401 to drive a pressure rod 402 to extend and retract, which, in conjunction with a pressure plate 404, applies pressure to the concrete block. Strength data is then obtained through a pressure sensor 403 and transmitted back to the control box 2 via an electrical connection between the pressure sensor 403 and the control box 2. Dust generated during this process is sucked out of the testing chamber 1 by the suction force generated by the fan 505 through the dust collection hood 501, and then filtered by two filter plates 504 inside the filter box 502, ensuring that the cleanliness inside the testing chamber 1 is not compromised by dust. The machine is powered by an electric actuator. Rod 605 drives cleaning roller 604. Cleaning roller 604 pushes the crushed stone on bearing plate 407 through waste port 601 into storage tank 701 along moving limit plate 602. Water is then supplied to water inlet pipe, and enters water spray pipe ring 607 through water pump 606. Water droplets are formed through nozzle 608 and enter detection box 1. The adsorption force of water droplets thoroughly cleans the inside of detection box 1. Finally, the liquid reaches storage tank 701 through drain hole 8. Then, the solid-liquid separation plate 702 in storage tank 701 separates the crushed stone and liquid for storage, thereby saving labor and time costs.
