Description
Technical Field
[0001] The utility model belongs to the technical field of sampling devices, and in particular relates to a sampling device for collecting data at a mixing station. Background Art
[0002] Concrete is abbreviated as "concrete": it refers to a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates; and water (which may contain admixtures and additives) mixed in a certain proportion and obtained by mixing. It is also called ordinary concrete. It is widely used in civil engineering. With the continuous development of the economy, my country's construction industry has developed rapidly, and the amount of infrastructure construction has increased. As one of the largest building materials used in modern construction projects, the demand for concrete has increased by leaps and bounds. In the concrete production process, various tests are required to design a concrete mix ratio that meets the requirements. Manual sampling is often required at the concrete mixing station for testing, and then it has to be placed on the testing equipment for testing. The existing sampling device has a relatively simple function. When the concrete consistency is large, the staff needs to wait a long time to complete the sampling work, and the concrete slurry sampling speed is slow. Utility Model Content
[0003] In view of the problems existing in the prior art, the purpose of the present invention is to provide a sampling device for collecting data in a mixing station.
[0004] In order to solve the above problems, the present invention adopts the following technical solutions:
[0005] The cam is threadedly connected to the bottom of the sampling cylinder, and a conical counterweight is provided on the lower side wall of the sampling cylinder. A sampling assembly is installed inside the sampling cylinder. The sampling assembly includes a piston, which is slidably installed in the interior of the sampling cylinder. The bottom of the piston is fixedly connected to a pull rod, which passes through the sampling cylinder and extends to the outside. The sampling cylinder is cut into an L shape to form a main shell and a side shell. The outer surfaces of the main shell and the side shell are provided with connected threaded grooves. When sampling, the sampling cylinder is inserted into the concrete, and the threaded cylinder is rotated. Through the cooperation of the mounting bracket and the retaining ring, the baffle is pulled up and the feed port is opened, so that concrete can enter the interior of the sampling cylinder. By pulling the pull rod upward, the piston moves upward to generate negative pressure in the interior of the sampling cylinder, and then the concrete can be quickly sucked in to complete the sampling. Compared with the existing technology, the sampling speed of the concrete is improved. After the sampling is completed, the threaded cylinder is rotated in the opposite direction to block the feed port to prevent the concrete from flowing out.
[0006] Preferably, the sampling assembly further includes an annular baffle, which is sleeved on the outside of the sampling cylinder.
[0007] Preferably, U-shaped mounting brackets are fixedly connected to both sides of the top of the baffle, and the mounting brackets are slidably connected to the sampling tube.
[0008] Preferably, a threaded barrel is threadedly connected to the top center of the mounting bracket, and the threaded barrel is rotatably connected to the sampling barrel.
[0009] Preferably, both sides of the side shell are protruded outward to form positioning protrusions.
[0010] Preferably, positioning grooves are respectively provided on both sides of the main shell.
[0011] Preferably, the outer surfaces of the main shell and the side shell are threadedly connected with a limiting ring. When the sampling cylinder is combined, the positioning protrusion is inserted into the inside of the positioning groove to accurately dock the main shell and the side shell, and the limiting ring is used to connect and fix the main shell and the side shell to form a combination of the sampling cylinder. When the sampling cylinder needs to be cleaned, the limiting ring is rotated to disengage from the side shell, and the sampling cylinder can be opened for cleaning.
[0012] Preferably, a handle is fixedly connected to the upper side wall of the sampling cylinder, and the handle is convenient for holding the sampling cylinder.
[0013] Beneficial effects of the utility model:
[0014] Compared with the prior art, the advantages of the present invention are:
[0015] 1. The utility model can open the feed port by rotating the threaded barrel, allowing concrete to enter the interior of the sampling barrel. By pulling the pull rod upward, the piston moves upward to generate negative pressure inside the sampling barrel, and then the concrete can be quickly sucked in to complete the sampling. Compared with the existing technology, the concrete sampling speed is improved.
[0016] 2. The utility model accurately docks the main shell and the side shell by inserting the positioning protrusion into the positioning groove, and fixes them together with the main shell and the side shell through a limiting ring, thereby forming a sampling cylinder.
