Description

Technical Field

[0001] The utility model belongs to the technical field of aggregate sampling, and in particular relates to an aggregate quality detection sampling device. Background Art

[0002] Aggregate, also known as "aggregate", is a granular material that plays a role in the skeleton and filling of concrete and mortar. There are two types of aggregate: fine aggregate and coarse aggregate. The diameter of fine aggregate particles is between 0.16 and 5 mm. Natural sand is generally used, such as river sand, sea sand and valley sand. When natural sand is lacking, artificial sand ground from hard rocks can also be used; the diameter of coarse aggregate particles is greater than 5 mm, and crushed stone and pebbles are commonly used. In order to ensure the quality of concrete, it is necessary to sample and test the aggregate before production. However, during sampling, since the aggregates are piled together, the existing sampling equipment can only sample part of the surface of the aggregate, and the sample taken is not representative. Moreover, after sampling, the sample in the sampling equipment cannot be quickly taken out, which affects the use efficiency. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0019] Embodiment 1, as Figure 1 , Figure 3 and Figure 4 As shown, an aggregate quality inspection sampling device is provided, wherein a lifting and rotating assembly 2 is installed on the top of a gantry 1, and a sampling assembly 3 is connected to the lifting and rotating assembly 2. The sampling assembly 3 includes an assembly tube 4, an electric push rod 5 is installed on the top of the inner side of the assembly tube 4, and a push plate 6 is connected to the power output end of the electric push rod 5. A sampling tube 7 is assembled and connected to the bottom of the assembly tube 4, and a cavity 8 is provided inside the sampling tube 7. The sampling tube 7 is provided with an opening 9 at the bottom of the cavity 8. The sampling tube 7 is also provided with a sampling port 10 connected to the inside of the cavity 8, and a sliding plate 6 is provided inside the opening 9. A push plate 11 is movably installed, and a barrel 12 is connected to the top of the push plate 11. Both the push plate 11 and the barrel 12 are slidably arranged in the cavity 8. The barrel 12 is provided with a plurality of feed ports 13 corresponding to the sampling ports 10. A baffle 14 is installed on the inner side of the top of the barrel 12. A connecting rod 15 is connected to the center of the baffle 14. The bottom of the connecting rod 15 is connected to the push plate 11. A top plate 16 is installed on the top of the connecting rod 15. A top column 17 is installed on the top of the top plate 16. The top of the top column 17 passes through the sampling barrel 7 and extends to its upper side.

[0020] In this embodiment, when sampling the accumulated aggregate, the door frame 1 is first installed at the aggregate accumulation location, and then the lifting and rotating assembly 2 is controlled to drive the sampling assembly 3 to move up and down and rotate, so that the sampling assembly 3 can move toward the aggregate. When the sampling tube 7 descends and contacts the aggregate, the aggregate pushes the push plate 11, so that the push plate 11 pushes the barrel 12 and the connecting rod 15, so that the barrel 12 slides in the cavity 8, and at the same time the connecting rod 15 pushes the top plate 16, and the top plate 16 pushes the top column 17 to move upward. When the sampling tube 7 continues to descend, the aggregate will enter the cavity 8 in the opening 9 for preliminary sampling. When the sampling tube 7 goes deep into the aggregate pile, the barrel 12 is pushed by the push plate 11, and the feed port 13 on the barrel 12 is aligned with the sampling port 10 on the surface of the sampling tube 7. The sampling tube 7 is continued to be controlled to descend for deep sampling, so that the aggregate enters the barrel 12 through the sampling port 10 and the feed port 13, thereby completing two sampling tasks, and then the lifting and rotating component 2 is controlled to drive the sampling component 3 to reset.

[0021] After resetting, when it is necessary to take out the sample in the sampling tube 7, the electric push rod 5 is controlled to start, so that the electric push rod 5 pushes the push plate 6, the push plate 6 pushes the top column 17, the top column 17 pushes the top plate 16, the top plate 16 pushes the connecting rod 15, and the connecting rod 15 pushes the push plate 11 while sliding in the baffle 14, so that the push plate 11 pushes the raw material in the opening 9 to discharge the sampling tube 7. When the raw material in the opening 9 is discharged, the top plate 16 is just located on the upper side of the baffle 14. At this time, the electric push rod 5 continues to be controlled to push the push plate 6, so that the push plate 6 pushes the top column 17, the top column 17 pushes the top plate 16, and the top plate 16 pushes the baffle 14, so that the baffle 14 pushes the sample in the barrel 12 to discharge the sampling tube 7, thereby facilitating the rapid removal of the sampled sample.
