Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a cement sampling device for building construction. Background Technique

[0002] Cement is an essential material in construction, and its quality characteristics determine the quality of the building. Therefore, before the construction of a building, it is necessary to sample and measure the quality of the cement. During building construction, due to the large amount of work, the demand for cement is correspondingly large. Therefore, many construction projects reserve cement in advance to keep up with the project progress. Since cement has high requirements for the storage environment, and the construction site environment is poor, it is necessary to sample the cement regularly.

[0003] The existing cement sample sampling device has a simple structure, generally a tubular sampler, which pierces the cement bag and extends into its interior for sampling at different positions. However, cement has a powdery structure, and when it accumulates together, it is mutually extruded and not easy to enter the sampler through the sampling hole. Even if a small amount of cement enters the sampler, it will accumulate near the sampling port, blocking the sampling port and resulting in insufficient sampling volume. This situation is particularly obvious when the cement is damp. Therefore, the utility model proposes a cement sampling device for building construction to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a cement sampling device for building construction to solve the problems raised in the above background technique.

A sampling shaft 305 is rotatably connected to the inner wall of the sampling cylinder 301 through a bearing. A screw blade 306 is welded on the shaft body of the sampling shaft 305. The number of the screw blades 306 is several. A partition plate 308 is welded on the shaft body of the sampling shaft 305. The partition plate 308 is arranged between two screw blades 306. A handwheel 307 is fixedly installed at the end of the sampling shaft 305.

[0030] Further, as Figure 3 shown, a square block 4 is welded at one end of the support cylinder 1. A rectangular groove 5 is opened on the end face of the square block 4. A first threaded cylinder 6 is fixedly installed on the inner wall of the rectangular groove 5 through bolts. The other end of the support cylinder 1 is sleeved with a second threaded cylinder 7, and the second threaded cylinder 7 is fixed to the support cylinder 1 through bolts. The sampling cylinder 301 is threadedly connected to both the first threaded cylinder 6 and the second threaded cylinder 7.

[0031] By setting the sampling assembly 3, during sampling, the sampling cylinder 301 is inserted into the cement bag by rotating the handle 302. After reaching the target depth, the handwheel 307 is rotated to drive the sampling shaft 305 to rotate, thereby driving the screw blade 306 on the sampling shaft 305 to rotate, and conveying the cement sample falling into the sampling cylinder 301 from the sampling port 304 backward, so as to prevent the cement sample from accumulating near the sampling port 304 and facilitating the collection of sufficient samples.

[0032] Specifically, as Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 and Figure 8 shown, the protection assembly 2 includes a fixing piece 201. A square tube 202 for the passage of the square block 4 is fixedly arranged on the fixing piece 201. A positioning cylinder 203 is fixedly installed on the surface of the fixing piece 201, and the positioning cylinder 203 is arranged inside the square tube 202. A one - character chute 204 is arranged on the inner wall of the positioning cylinder 203. A T - shaped hook 205 is slidably connected to the inner wall of the one - character chute 204. A round hole is opened at the bottom end of the positioning cylinder 203. The T - shaped hook 205 used here is made of soft plastic, and its hook claws have a certain flexibility and can be extruded from the round hole on the positioning cylinder 203.

[0033] It should be noted that a pressing column 8 is fixedly installed on the end face of the square block 4.
