[0026] like Figure 1-Figure 5 The concrete sampling device comprises: a sampling tube 1, a conical head 18, a spiral auger 8, a sample tube 7 and a handle 10.

[0027] The sampling tube 1 extends in the front-to-back direction. The sampling tube 1 is composed of a plurality of connecting tubes 4 which are detachably spliced ​​end to end in the front-to-back direction. The frontmost connecting tube 4 is the feed tube 2, and the rearmost connecting tube 4 is the discharge tube 3. A feed port 5 is provided on the tube wall of the feed tube 2, and a discharge port 6 is provided on the tube wall of the discharge tube 3. A sample cylinder 7 is detachably provided at the discharge port 6, and a scale is provided on the sample cylinder 7.

[0028] The conical head 18 is detachably provided with the front end of the feed pipe 2, the spiral auger 8 is coaxially rotatable in the sampling tube 1, the main shaft 9 of the spiral auger 8 extends backward and is connected to the discharge pipe 3 and the handle 10, and the handle 10 is fixed with a plurality of foldable and extended handles 11 arranged at intervals along the circumference of the main shaft 9.

[0029] When the device is in use, the sampling tube 1 is inserted into the concrete to be sampled, and then the spiral auger 8 is manually rotated by the handle 10. After the concrete flows into the sampling tube 1 through the feed port 5, it is transported to the discharge port 6 under the action of the rotating spiral auger 8, and then falls into the sample tube 7, thereby realizing the collection of concrete samples.

[0030] In the present device, a conical head 18 is provided at the front end of the sampling tube 1, thereby reducing the resistance of the sampling tube 1 inserted into the concrete; a spiral auger 8 is used to transport concrete, and the transport form is simple and easy to implement; the rotation of the spiral auger 8 is achieved by manually rotating the handle 10, and the manual structure will be simpler, and the cost of the device will be lower, which is more suitable for popularization and use. In addition, a foldable and extended handle 11 is provided on the handle 10, so the extended handle 11 can be selected to make the rotation more labor-saving; a scale is set on the sample tube 7 for storing concrete samples, so that accurate quantitative sampling can be achieved.

[0031] In addition, the device as a whole adopts a detachable design. The sampling tube 1, conical head 18 and sample tube 7 used are all detachable. When the concrete sampling is completed, the relevant parts can be removed for cleaning, thereby preventing the concrete from hardening and solidifying and adhering to the device, thereby affecting the subsequent sampling use.

[0032] In specific applications, such as Figure 1 and Figure 2 As shown, between any two adjacent connecting tubes 4 in the front-to-back direction, a rear end of one connecting tube 4 is provided with an annular convex edge 12, and a front end of the other connecting tube 4 is provided with an annular groove, an outer peripheral wall of the convex edge 12 is provided with an external thread, and an inner peripheral wall of the groove is provided with an internal thread, and the external thread is threadedly connected with the internal thread, thereby realizing the detachable splicing connection of the sampling tube 1, and this connection form is simple and easy to realize.

[0033] like Figure 2As shown, the conical head 18 is hollow inside, so that the weight of the conical head 18 can be reduced. A threaded blind hole is provided at the rear end of the conical head 18, and a stud 13 is provided at the front end of the feed pipe 2. The threaded blind hole is threadedly connected to the stud 13, thereby realizing the detachable connection between the conical head 18 and the feed pipe 2.

[0034] like Figure 1 and Figure 3 As shown, a discharge pipe 19 is provided at the discharge port 6, and a clamping shaft 14 is provided on the outer tube wall of the discharge pipe 19. An L-shaped clamping groove 15 is provided on the upper edge of the sample tube 7. The clamping groove 15 includes a first groove portion and a second groove portion. The first groove portion extends in the up-down direction, and the lower end of the first groove portion is connected to the second groove portion. The second groove portion extends in the horizontal direction. The first groove portion and the second groove portion jointly define the L-shaped clamping groove 15.

[0035] When in use, the clamping shaft 14 passes downward through the first groove, and the sample tube 7 is rotated so that the clamping shaft 14 is clamped into the second groove, so that the sample tube 7 can be firmly connected with the discharge pipe 19. When the sample tube 7 needs to be removed, the sample tube 7 is rotated in the opposite direction, and then the sample tube 7 is removed downward, which is very convenient.

[0036] like Figure 4 and Figure 5 As shown, the handle 11 includes an outer rod body 16 and an inner rod body 17, the outer rod body 16 is fixedly connected to the handle 10, the inner rod body 17 is pivotally connected to the outer rod body 16, and a storage groove is provided on the outer rod body 16, and the inner rod body 17 is rotated and stored in the storage groove. Therefore, when the inner rod body 17 is rotated so that the inner rod body 17 extends from the storage groove and the outer rod body 16, the handle 11 will be lengthened at this time, and it will be more labor-saving when rotating the handle 10. When it is not used, the inner rod body 17 can be folded and stored in the storage groove.

[0037] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
