Description

Technical Field

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

[0002] Concrete is a general term for engineering composite materials that are made of aggregates bonded together by cementitious materials. The term concrete usually refers to cement as the cementitious material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion and mixed to obtain cement concrete, also known as ordinary concrete. It is widely used in civil engineering. Concrete has the characteristics of abundant raw materials, low price and simple production process, which leads to its increasing usage.

[0003] Utility model patent CN216050792U discloses a concrete sampling device, including a shell, a rotating shaft, an upper cover, a conical head and an opening and closing unit; the shell is a cylindrical body with a hollow interior and an opening at the top, a slide groove is provided at the upper part of the front side of the shell, a sample inlet is provided at the lower part of the front side of the shell, a sample outlet is provided at the upper part of the rear side of the shell, and handrails are installed on the left and right sides of the upper part of the shell;

However, when sampling, both hands are required to operate, and the rotating handle needs to be rotated to make it deeper when necessary, which is laborious. Moreover, when cleaning the inside and outside after sampling, it is extremely inconvenient to clean the concrete inside because it cannot be disassembled. If it is not cleaned thoroughly, it will affect the next use, so the practicality is low. Utility Model Content

[0023] Hold the handle 11 with one hand, then insert the lower end of the rod body 1 into the concrete to be sampled with the drill bit 3, and pull the handle to collect the concrete into the collecting tank 2. It can be operated with one hand, which is convenient and quick. At the same time, a cleaning structure 4 is provided in the collecting tank 2, which makes cleaning the collecting tank 2 more convenient, efficient and practical.

[0024] In another embodiment, see Figures 1 to 4 The cleaning structure 4 includes a cleaning block 41 that matches the inner diameter of the collecting tank 2. The cleaning block 41 is arranged at the top of the collecting tank 2 and is slidably connected to the inner wall of the collecting tank 2. A connecting rod 42 is slidably inserted into the upper side of the cleaning block 41 in the rod body 1. The connecting rod 42 extends downward into the collecting tank 2 and is fixedly connected to the upper side of the cleaning block 41. A shift block 43 is transversely fixed on the top of the connecting rod 42. A movable groove 13 is longitudinally opened at the side wall of the rod body 1 corresponding to the shift block 43. The shift block 43 can extend from the movable groove 13 to the outside of the rod body 1. A first movable cavity 14 is opened at the part of the rod body 1 corresponding to the connecting rod 42 located in the rod body 1. A limiting slider 44 slidably connected to the side wall of the first movable cavity 14 is fixedly provided on the top of the rod body 1 corresponding to the first movable cavity 14. A first spring 45 is provided at the lower side of the limiting slider 44 in the first movable cavity 14, and the first spring 45 is inserted on the connecting rod 42;

[0025] When the collecting tank 2 needs to be cleaned, the drill bit 3 is first rotated and unscrewed, and then the shifting block 43 is pushed downward. At this time, the cleaning block 41 scrapes the concrete remaining on the inner wall of the collecting tank 2 from top to bottom. The first spring 45 is reset to drive the cleaning block 41 to reset upward, which is convenient for the next sampling work.

[0026] In this embodiment, the rod body 1 is further provided with a matching arc-shaped baffle 46 at the position corresponding to the movable groove 13, the lower side of the arc-shaped baffle 46 passes through the lower side wall of the movable groove 13 and is slidably connected thereto, a connecting block 47 is transversely fixedly provided at the bottom of the arc-shaped baffle 46, and the rod body 1 is longitudinally provided with a second movable cavity 15 corresponding to the connecting block 47, the right side of the second movable cavity 15 is connected to the first movable cavity 14, the connecting block 47 extends rightward into the first movable cavity 14, and is fixedly connected to the left side of the limit slider 44;

[0027] When not being cleaned, the movable groove 13 is closed by the arc baffle 46 to prevent concrete from entering the movable groove 13 during sampling and affecting its later use. At the same time, when the shifting block 43 is moved, the limit slider 44 is driven to move downward, thereby driving the arc baffle 46 to move downward so that it will not affect the normal use of the shifting block 43.

[0029] During sampling, when the rod body 1 reaches the specified position and the handle 12 is pulled, the cover plate 5 is pulled up under the traction of the steel wire 6, thereby opening the feed port 17 and allowing the concrete to enter the collecting tank 2. After the collection is completed, the handle 12 is released and the cover plate 5 is closed under the resetting action of the second spring 52. It can be operated with one hand, which is simple and convenient.
