Description

Technical Field

[0001] The utility model relates to the technical field of cement sampling, in particular to a cement detection sampling mechanism. Background Art

[0002] Cement is a commonly used building material. It is a powdery substance made from limestone, clay, ore and other raw materials through processes such as crushing, mixing and calcining. It is mainly used in the production of building materials such as concrete, mortar and blocks. It is also widely used in road repair, foundation treatment and other construction fields.

[0003] After cement is processed, it needs to be tested to understand the composition, physical properties and chemical properties of cement, so as to ensure that its quality meets the standard requirements. This requires the use of a sampling device to sample and store cement. However, when sampling, most of the samples are taken from the surface of cement at the storage location. The information of the outermost part of the cement cannot fully understand the uniformity and quality of the entire batch of cement, resulting in a decrease in the accuracy and representativeness of the sampling. For this reason, we propose a cement detection sampling mechanism to solve the existing problems. Utility Model Content

The cone reduces the resistance of the material collection barrel when it is inserted into the cement process, and the cone is used to realize rotation and fixation at the lower end of the material collection barrel.

[0007] Preferably, the inner wall of one side of the sampling tube is provided with multiple sets of equally spaced guide rails located on both sides of the material taking port, and both ends of the closing plate are provided with sliders, which are slidably sleeved on the outer wall of the guide rails.

[0008] Preferably, the mounting blocks are provided with through holes, and a guide rod whose upper end is connected to the support block is slidably inserted in the through holes, and the guide rod is slidably inserted in the spring. During the extension and retraction of the spring, the through holes in the mounting blocks slide on the outer wall of the guide rod, and the guide rod limits the spring and guides the upper end of the closing plate.

[0009] Preferably, one end of the connecting rope is connected to the closing plate, and the inner wall of one side of the sampling tube is provided with equally spaced collars, and the lower end of the pull rod is slidably inserted into the collar. When the pull rod is pulled up, the connecting rope is stretched, and then the closing plate is driven up, the closing plate is linked, and when the guide rod moves longitudinally, it is slidably guided by the collar.

[0010] Preferably, the lower end of the sampling barrel is open, a sliding sleeve is embedded in the upper end of the sampling barrel, and the upper end of the pull rod is slidably inserted into the sliding sleeve. The material inside the sampling barrel is discharged through the opening, and the sliding sleeve inside the upper end of the sampling barrel supports the guide rod slidingly, so that the upper end of the guide rod slides longitudinally inside the upper end of the sampling barrel.

[0011] Preferably, a pull ring is provided at the upper end of the pull rod, and a handle is provided at the upper end of the sampling tube. Both the pull ring and the handle are easy for the staff to grasp, so that the staff can use the guide rod and the sampling tube conveniently.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-Figure 4 As shown, a cement detection sampling mechanism proposed by the utility model comprises a sampling tube 1, a pull rod 7, a mounting block 11 and a closing plate 12, wherein an evenly spaced feed port 2 is provided inside one end of the sampling tube 1, a cone tube 3 is provided at the lower end of the sampling tube 1, a mounting ring 4 is provided at the upper end of the cone tube 3, a threaded sleeve is sleeved on the outer wall of the threaded sleeve on the lower end outer wall of the sampling tube 1, a thread that meshes with the threaded sleeve is provided on the inner wall of the mounting ring 4, an evenly spaced closing plate 12 is provided inside the sampling tube 1 and is located on one side of the feed port 2, a plurality of evenly spaced guide rails 13 are provided on the inner wall of one side of the sampling tube 1 and are located on both sides of the feed port, sliders 14 are provided at both ends of the closing plate 12, the sliders 14 are slidably sleeved on the outer wall of the guide rails 13, a mounting block 11 is provided on the upper end of the closing plate 12, and a spring 10 is provided on the upper end of the mounting block 11 , the inner wall of one side of the sampling barrel 1 is provided with equidistantly distributed support blocks 18, the lower ends of the support blocks 18 are provided with springs 10 connected to the mounting blocks 11, through holes 15 are opened inside the mounting blocks 11, and guide rods 16 connected to the upper ends of the support blocks 18 are slidably inserted inside the through holes 15, and the guide rods 16 are slidably inserted inside the springs 10, a pull rod 7 is provided inside the sampling barrel 1, and equidistantly distributed connecting ropes 8 are provided on the outer wall of one side of the pull rod 7, and one end of the connecting rope 8 is connected to the closing plate 12, and equidistantly distributed rings 9 are provided on the inner wall of one side of the sampling barrel 1, and the lower ends of the pull rods 7 are slidably inserted inside the rings 9, and the lower end of the sampling barrel 1 is open, and a sliding sleeve 17 is embedded and installed inside the upper end of the sampling barrel 1, and the upper end of the pull rod 7 is slidably inserted inside the sliding sleeve 17, and a pull ring 6 is provided on the upper end of the pull rod 7, and a handle 5 is provided on the upper end of the sampling barrel 1.

[0021] Based on the implementation steps of Example 1: the inspector grasps the handle 5, and inserts the sampling tube 1-cone tube 3 as the plug-in point into the cement, and the material taking port is completely immersed in the cement. At this time, the pull ring 6 is pulled to drive the pull rod 7 to rise, and the connecting rope 8 is forced to pull the closing plate 12 to drive the closing plate 12 to rise, and the material taking port loses its shielding. The cement enters the sampling tube 1 through the open pores of the material taking port. By opening sampling feed ports 2 at different heights, samples from different depths of cement can be obtained, so that the reference data value of the cement batch detection is improved;

[0022] According to the height of the closing plate 12, the flow rate of cement entering the material taking barrel will change. The opening of the closing plate 12 to the material taking port is adjusted by the lifting height of the pull rod 7 to control the flow rate of cement input into the material taking barrel. Through this small flow rate of material taking, when the sampling barrel 1 is horizontally inserted into the cement, the cement is carried on the inner wall of one side of the sampling barrel 1, and cement at different positions can be inserted multiple times to perform multi-point and multi-position sampling, further improving the diversity of cement sampling.

[0023] After the pull rod 7 is relaxed, the spring 10 pushes the mounting block 11 downward by its own elasticity, so that the closing plate 12 automatically closes the material opening, thereby avoiding the spillage of cement after sampling and effectively storing the sampled cement.
