Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, in particular to a concrete sampling device for civil engineering. Background Art

[0002] In modern engineering construction work, concrete is one of the most commonly used building materials. It is mainly obtained by mixing gravel, stone powder, cement, water, etc. in a certain proportion. After it solidifies, it is as hard as rock. In the production of concrete, different additives and special cements are generally required to adjust the quality of concrete. The quality of concrete is very important, so sampling and testing the concrete before it is put into use is a very important work link in the project.

[0003] Most of the existing concrete sampling devices for civil engineering are only equipped with a sampling port, which means that only concrete of a single depth can be sampled during sampling, and the conditions of concrete at different depths cannot be observed. Moreover, after the existing concrete sampling devices for civil engineering complete the sampling and pour out the concrete inside, some concrete will still adhere to the inner wall of the sampling tube. If it is not cleaned, it will be mixed with the concrete sampled next time, resulting in inaccurate data. Therefore, manual cleaning is required by staff, which is inconvenient. For this reason, we propose a concrete sampling device for civil engineering. Utility Model Content

In addition, after the existing concrete sampling device for civil engineering completes the sampling and pours out the concrete inside, part of the concrete will still adhere to the inner wall of the sampling tube. If it is not cleaned, it will mix with the concrete of the next sampling, resulting in inaccurate data.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a concrete sampling device for civil engineering, comprising a sampling tube and a mounting rod, wherein the mounting rod is located in the inner cavity of the sampling tube, sampling ports are opened on the front and rear sides of the outer wall of the sampling tube, and the sampling ports on the front and rear sides are arranged in sequence from top to bottom, storage bins are opened on the front and rear sides of the interior of the sampling tube, and the storage bins on the front and rear sides are arranged in sequence from top to bottom, a transmission bin is opened on the upper side of the interior of the sampling tube, a first motor is fixedly connected to the front side wall of the inner cavity of the transmission bin, a driving rod is fixedly connected to the rear end of the power output shaft of the first motor, a driving gear is fixedly connected to the front and rear sides of the outer wall of the driving rod, a gear driven screw is rotatably connected to the front and rear sides of the bottom of the inner cavity of the transmission bin, the bottom ends of the gear driven screws on the front and rear sides penetrate the transmission bin, the storage bin and the sampling port and extend to the bottom of the inner cavity of the bottom sampling port, baffles are screwed to the outer walls of the gear driven screws on the front and rear sides, and the baffles on the front and rear sides are arranged in sequence from top to bottom.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The concrete sampling device for civil engineering, when sampling concrete, after the sampling tube enters the concrete and reaches the designated position, the first motor is started to drive the driving rod to rotate, so that the driving rod drives the driving gear to drive the gear driven screw meshing with it to rotate, so that the baffle installed on the gear driven screw moves up with the rotation of the gear driven screw and enters the storage bin, and the obstruction of the sampling port is removed, so that the concrete enters the sampling tube through the sampling port. Since three sampling ports are arranged from top to bottom, concrete of different depths can be sampled. After the sampling is completed, the first motor is reversed, so that the driving gear drives the gear driven screw to reverse, so that the baffle descends to seal the sampling port, and then the sampling tube is lifted to the ground, and the sampling port is opened to observe the concrete condition in the sampling tube, so that concrete of different depths can be sampled, thereby increasing the accuracy of the data.

[0018] 2.

Then the third motor is started to drive the threaded rod to rotate, so that the scraper installed on the threaded rod descends with the rotation of the threaded rod, and the concrete attached to the inner wall of the sampling tube is cleaned from top to bottom. After the cleaning is completed, the scraper is reset by reversing the third motor, so that the concrete on the inner wall of the sampling tube can be automatically cleaned, saving time and effort.
