Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cement sampling, and more specifically, to a bagged cement sampler. Background Art
[0002] When cement is brought into the construction site for renovation, its variety, grade, packaging or bulk warehouse number and factory date should be checked, and its strength stability and other necessary performance indicators should be re-tested. When sampling the bagged cement brought into the site, it is necessary to poke a hole in the cement bag to take out the sample, so a bagged cement sampler is needed. Some existing bagged cement samplers cannot actively fill the cement sample into the sampler when in use, making it difficult for operators to collect sufficient cement samples, and the practicality is low. To solve the above problems, we have launched the following device. Utility Model Content

At the same time, the movable plate drives the movable block and the first U-shaped seat to rise, so that the connecting rod rotates and pushes the second U-shaped seat and the sampling plate, so that the sampling plate rotates around the positioning column, so that the sampling port is opened, and a vacancy is formed between the sampling plate and the sampling port. The cement sample automatically fills the vacancy under the action of gravity, and then people release the handle and reset the sample collecting plate through the spring restoring force, so that the cement sample at the vacant position is pushed into the sampling tube from the sampling port by the sample collecting plate, which is convenient for people to actively fill the cement sample into the sampler.

[0030] By adopting the above technical scheme, the bagged cement sampler is provided with a pull rod 15, a spring 17 and a push rod. When people insert the device into the cement bag, people use their right hand to pull the pull rod 15 through the handle 16, thereby driving the movable plate 8 to rise and compress the spring 17. At the same time, the movable plate 8 drives the movable block 9 and the first U-shaped seat 11 to rise, so that the connecting rod 12 rotates and pushes the second U-shaped seat 13 and the sampling plate, so that the sampling plate rotates around the positioning column 5, so that the sampling port 2 is opened, and a vacancy is formed between the sampling plate and the sampling port 2. The cement sample automatically fills the vacancy under the action of gravity, and then people release the handle 16, and the sample collecting plate 3 is reset by the restoring force of the spring 17, so that the cement sample at the vacant position is pushed into the sampling tube 1 from the sampling port 2 by the sample collecting plate 3, which is convenient for people to actively fill the cement sample into the sampler.
[0031] Specifically, an external threaded ring 18 is fixedly connected to the bottom of the sampling tube 1, and a hole-opening drill bit 19 is arranged directly below the sampling tube 1. An internal thread groove 20 is provided on the upper surface of the hole-opening drill bit 19. The hole-opening drill bit 19 is threadedly connected to the surface of the external threaded ring 18 through the internal thread groove 20, and an anti-slip pattern 21 is provided on the surface of the hole-opening drill bit 19.
[0032] By adopting the above technical solution, the bagged cement sampler is provided with an external thread ring 18, an internal thread groove 20 and an anti-skid pattern 21. When taking out the collected samples, people continuously rotate the hole-opening drill bit 19 through the anti-skid pattern 21 on the surface of the drill bit, so that the external thread ring 18 rotates relative to the internal thread groove 20. With the mutual cooperation between the external thread ring 18 and the internal thread groove 20, the hole-opening drill bit 19 is separated from the sampling tube 1, so that people can pour the collected cement samples from the sampling tube 1, which is convenient for people to take out the collected samples.
[0033] Specifically, there are two groups of sample inlets 2 and sample collecting plates 3 , which are symmetrically arranged on the surface of the sampling tube 1 .
[0034] Specifically, there are two groups of limiting grooves 6 and limiting blocks 7 , which are symmetrically arranged on the inner wall of the sampling tube 1 .
[0035] Specifically, the cross section of the handle 16 is in the shape of an inverted convex letter "U".
[0036] Specifically, the surface threads of the external thread ring 18 and the inner wall threads of the internal thread groove 20 are adapted to each other.
[0037] Specifically, a rubber sleeve 22 is fixedly connected to the surface of the sampling tube 1 , and a dust-blocking ring 23 is fixedly connected to the surface of the sampling tube 1 close to the rubber sleeve 22 .
[0038] The working principle of the utility model is as follows: when in use, people first hold the rubber sleeve 22 with their left hand, and then guide the sampling tube 1 into the cement bag through the hole drill 19. The dust-blocking ring 23 can prevent the handle from getting cement dust on the rubber sleeve 22 and people's hands dirty during the process. Then people use their right hand to pull the pull rod 15 through the handle 16, thereby driving the movable plate 8 to rise and compress the spring 17. At the same time, the movable plate 8 drives the movable block 9 and the first U-shaped seat 11 to rise, so that the connecting rod 12 rotates and pushes the second U-shaped seat 13 and the sampling plate, so that the sampling plate rotates around the positioning column 5, so that the sampling port 2 is opened, and a vacancy is formed between the sampling plate and the sampling port 2, and the cement sample is pulled under the action of gravity. The empty space is automatically filled, and then people release the handle 16, and the sample collecting plate 3 is reset by the restoring force of the spring 17, so that the cement sample at the empty space is pushed into the sampling tube 1 from the sampling port 2 by the sample collecting plate 3, thereby actively filling the cement sample into the sampler, and then people can repeat the above operation multiple times according to the demand for cement samples. After the cement sample is collected, people continue to rotate the hole-opening drill bit 19 through the anti-slip groove 21 on the surface of the drill bit, so that the external thread ring 18 rotates relative to the internal thread groove 20. With the mutual cooperation of the external thread ring 18 and the internal thread groove 20, the hole-opening drill bit 19 is separated from the sampling tube 1, so that people can pour the collected cement sample from the sampling tube 1 to take out the collected sample.
