When the compressive strength of the cement test block is tested, the box door 4 is opened, and the cubic cement block is placed on the upper surface of the placement table 13, and then the first cylinder 12 is started. The first cylinder 12 is started to drive the clamping plate 11 to clamp the cement test block, and then the hydraulic cylinder 5 is started to drive the pressure sensor 6 and the pressure plate 7 to move downward. When the pressure plate 7 moves downward, the cement test block is squeezed, and the state of the cement test block is observed through the glass window 16. When observing that the cement test block is broken, the pressure value recorded by the display screen 17 is recorded, and the compressive strength of the cement test block is recorded. Then, the cleaning component 2 is used to clean the cement test block. When there are more cement test blocks in the collection box 14, the box door 4 is opened, and then the collection box 14 close to the box door 4 is taken out, and then the collection box 14 away from the box door 4 is rotated along the support rod 10, so that the collection box 14 rotates 180°, and then the collection box 14 is taken out and the cement test block is poured out.

[0028] Reference Figure 1 , Figure 2 and Figure 4As shown, the cleaning component 2 includes a second cylinder 201, which is fixedly installed in the third fixing hole 15, and the second cylinder 201 is connected to a connecting plate 202. A threaded hole 203 is provided at the center position of the side of the connecting plate 202 away from the second cylinder 201, and a connecting rod 204 is threadedly movably connected to the threaded hole 203. A movable plate 205 is fixedly sleeved outside the connecting rod 204, and a push plate 207 is connected to the end of the connecting rod 204 away from the connecting plate 202. A plurality of groups of evenly distributed bristles 206 are provided on the lower surface of the movable plate 205, and the bristles 206 are in contact with the upper surface of the placement table 13, and the push plate 207 is not in contact with the upper surface of the placement table 13. The push plate 207 is tilted, and the second cylinder 201 is started, and the second cylinder 201 starts to drive the connecting plate 202 moves horizontally. When the connecting plate 202 moves horizontally, it drives the connecting rod 204, the movable plate 205, the bristles 206 and the push plate 207 to move horizontally. When the push plate 207 moves horizontally, the larger cement test block is pushed into the collection box 14. The bristles 206 clean the upper surface of the placement table 13 and sweep the smaller sand and debris into the collection box 14. The bristles 206 move back and forth through the reciprocating extension and contraction of the second cylinder 201, thereby realizing the back and forth movement of the bristles 206, thereby cleaning the upper surface of the placement table 13 back and forth. When the bristles 206 need to be cleaned, the second cylinder 201 is started to drive the connecting rod 204 to move toward the direction of the box door 4. When the bristles 206 move away from the placement table 13, the movable plate 205 is rotated to release the threaded connection between the connecting rod 204 and the mounting plate.

[0029] Working principle: When testing the compressive strength of cement test blocks (according to GB50107 "Concrete Strength Test and Evaluation Standard": the standard value of cubic compressive strength refers to a cubic test piece with a side length of 150 mm made and maintained according to the standard method), open the box door 4, place the cubic cement block on the upper surface of the placement table 13, and then start the first cylinder 12. The first cylinder 12 starts to drive the clamping plate 11 to clamp the cement test block, and then start the hydraulic cylinder 5 to drive the pressure sensor 6 and the pressing plate 7 to move downward. When the pressing plate 7 moves downward, it squeezes the cement test block, and observes the state of the cement test block through the glass window 16. When observing that the cement test block is broken, record the pressure value recorded by the display screen 17 and record the compressive strength of the cement test block;

[0030] Subsequently, the cleaning component 2 is used to clean the cement test block. The specific method is to start the second cylinder 201. The second cylinder 201 starts to drive the connecting plate 202 to move horizontally. When the connecting plate 202 moves horizontally, it drives the connecting rod 204, the moving plate 205, the brush 206 and the push plate 207 to move horizontally. When the push plate 207 moves horizontally, the larger cement test block is pushed into the collection box 14. The brush 206 cleans the upper surface of the placement table 13 and sweeps smaller sand and debris into the collection box 14. The back and forth movement of the brush 206 is achieved by the back and forth extension and retraction of the second cylinder 201, thereby cleaning the upper surface of the placement table 13 back and forth. When the bristles 206 need to be cleaned, the second cylinder 201 is started to drive the connecting rod 204 to move toward the box door 4. When the bristles 206 move away from the placement table 13, the movable plate 205 is rotated to release the threaded connection between the connecting rod 204 and the mounting plate. Through the setting of the cleaning component 2, it is convenient to clean the fine sand and debris on the surface of the placement table 13, and the placement table 13 is cleaned conveniently. The fine sand and debris will not get stuck in the gap between the push plate 207 and the placement table 13, thereby preventing the push plate 207 and the placement table 13 from being worn, thereby improving the service life of the push plate 207 and ensuring the cleaning effect.

[0031] When there are a lot of cement test blocks in the collecting box 14, open the door 4, then take out the collecting box 14 close to the door 4, then rotate the collecting box 14 away from the door 4 along the support rod 10, so that the collecting box 14 rotates 180°, then take out the collecting box 14 and pour out the cement test blocks.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
