[0013] Furthermore, a bottom frame is provided at the lower end of the shield, and the bottom frame is located above the storage box;

[0014] Specifically, after the bottom frame is lowered, it fits with the upper end of the storage box to shield the space above the storage box.

[0022] Compared with the prior art, the advantages of the present invention are:

[0023] The utility model rolls and conveys the concrete blocks by conveying rollers that are tilted upward from the bottom, and rolls the concrete blocks into the storage box. After the test, the storage box can be turned over to facilitate the discharge of the concrete. The hydraulic rod is used as the power to press the concrete blocks through the longitudinally moving pressure sensing head, so that the concrete can be effectively tested for its compressive strength. At the same time, the material loading process is convenient.

[0024] At the same time, because the fragments generated by the compression test of concrete blocks are intercepted by the storage box, the opening of the storage box is covered by a shield to prevent the concrete fragments from scattering, making it easier for staff to clean and collect the concrete blocks after testing.

[0045] During house construction, the concrete blocks solidified with the same materials are supported at the bottom by the conveying roller 206, which pushes the concrete blocks to the storage box 208. The motor 207 drives the mounting shaft 210 to rotate, driving the storage box 208 to rotate. The inner wall of one side of the storage box 208 corresponds to the conveying roller 206. At this time, the concrete blocks are pushed into the storage box 208. The guide roller 209 in the storage box 208 rolls and supports the concrete blocks. When the concrete blocks are transported to the storage box 208, the motor 207 drives the mounting shaft 210 to rotate, driving the opening of the storage box 208 to face upward, driving the hydraulic rod 204 to drive the pressure sensing head 211 to descend, pressing the concrete blocks inside the storage box 208. During the pressing process of the concrete blocks, the pressure value is displayed on the display panel 205, and then the concrete blocks are subjected to compression testing. During the testing process, the concrete blocks avoid being directly carried to the testing location by the staff. Through the rolling support, the concrete blocks are transported labor-saving during testing, avoiding the problem of the staff having to carry them to the designated location more laborious.
