AI Technical Summary
During the sampling process of existing bagged cement samplers, it is difficult for cement to move to the back end, resulting in insufficient sampling volume and inability to ensure sampling quality.
A bagged cement sampler is designed including a sleeve and a sampling cylinder rotatably connected to the sleeve. By providing a shaft and a spiral disc in the sampling cylinder, the rotation of the spiral disc drives the cement sample to move to the rear, so that the space at the inlet hole is vacant, so that the subsequent cement falls into the sampling cylinder.
Through this design, the sampling quantity can be guaranteed and adapted to scenarios with large sampling quantity, which improves the practicality of the sampler.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cement samplers, in particular to a bagged cement sampler. Background Art
[0002] At present, cement samplers are usually used for continuous sampling of powdered materials such as raw materials out of the cement mill, raw materials entering the kiln, coal powder out of the cement mill, coal powder entering the kiln, cement out of the cement mill, and cement leaving the factory. In engineering construction, cement sampling is also very important. Timely and reasonable sampling and testing can prevent safety hazards caused by poor cement quality. Therefore, relevant national technical standards and specifications stipulate that cement samples with the same number must be collected at different locations.
[0003] An existing bagged cement sampler has a through hole formed on a sleeve and a sampling tube. After the sleeve is inserted into a cement bag, the sleeve is reciprocated to allow cement to pass through the through hole and fall into the sampling tube. The sampling tube is then rotated to allow the through hole to rotate to the bottom of the sleeve. The sleeve is used to seal the sampling tube to achieve sampling. However, cement moves into the sampling tube only by gravity, and the sampling tube has a certain length. After cement falls into the sampling tube, it is difficult to move to the rear end, which fills up the space at the sampling hole. Subsequently, cement no longer moves into the sampling tube, making it difficult to ensure the sampling volume. Therefore, a bagged cement sampler is proposed for improvement. Utility Model Content
[0004] The purpose of the present invention is to solve at least one of the above technical deficiencies.
[0005] Therefore, one purpose of the utility model is to provide a bagged cement sampler to solve the problems mentioned in the background technology and overcome the deficiencies in the prior art.
[0006] In order to achieve the above-mentioned purpose, an embodiment of the utility model provides a bagged cement sampler, comprising a sleeve and a sampling barrel rotatably connected in the sleeve, the front end of the sleeve is fixedly connected to a puncture head, a feeding hole is provided on the sleeve, the rear end of the sampling barrel is fixedly connected to a first handle, the rear end of the sampling barrel is fixedly connected to a second handle, and a sampling hole is provided on the sampling barrel;
[0007] A shaft is rotatably connected inside the sampling tube, a third handle is fixedly connected to the rear end of the shaft, a spiral disk is fixedly connected to the shaft, barrier rings are provided on both sides of the sampling hole of the sampling tube, observation windows are provided at the rear ends of the sampling tube and sleeve, a prompt block is fixedly connected to the rear end of the sleeve, and a marking block is fixedly connected to the rear end of the sampling tube.
[0008] Preferably, from any of the above schemes, both ends of the sampling tube are rotatably connected to the sleeve via bearings, and the size of the feed hole is not greater than the size of the injection hole.
[0009] Preferably, any of the above solutions is that the first handle, the second handle and the third handle are all provided with anti-slip pads.
[0010] The above technical solution is adopted: the sleeve provides an installation platform for the sampling tube and other structures, and can block the sampling hole on the sampling tube to prevent the sample cement entering the sampling tube from flowing out again. The puncture head can facilitate the sleeve to pierce the cement bag so that sampling can be performed using the sampling structure. The feed hole allows cement to pass through it and then enter the sleeve. A first handle is set at the rear end of the sleeve to facilitate the staff to hold the sleeve so as to keep the sleeve stable or rotate the sleeve. The size of the feed hole is not larger than the sampling hole, so that the feed hole can enter the sampling hole smoothly. Anti-skid pads are set on the first handle, the second handle and the third handle to avoid hand slippage and improve stability when holding.
[0011] Preferably, in any of the above schemes, the first handle, the second handle and the third handle each include two symmetrically arranged grip rods.
[0012] Preferably, any of the above schemes is that the injection hole adopts an inverted cone structure that is wide outside and narrow inside, and the shaft is rotatably connected to the middle part of the sampling tube.
[0013] The above technical solution is adopted: the first handle, the second handle and the third handle of the two handles are symmetrically arranged, so that the staff can hold it according to the needs. The sampling tube is used to accommodate the sample cement, and an injection hole is provided on it, so that the sample cement can enter the sampling tube. The injection hole adopts an inverted cone structure, so that the cement sample after entering the sleeve can smoothly pass through the injection hole and fall into the sampling tube. The shaft rod provides a mounting platform for the spiral disk and can drive the spiral disk to rotate. The third handle is set at the rear end of the shaft rod to facilitate the staff to rotate the shaft rod.
[0014] Preferably, any of the above schemes is that a plurality of balls are embedded on a side of the barrier ring close to the sleeve, and the observation window has an arc-shaped structure.
[0015] Preferably, any of the above schemes is that the observation window, the material passing hole and the sampling hole are arranged on the same surface of the sleeve and the sampling tube.
[0016] The above technical solution is adopted: when the shaft is rotated, the spiral disk rotates with the shaft. Under the rotation of the spiral disk, the cement sample entering the sampling barrel is driven by the spiral disk to move to the rear of the sampling barrel, so that the space at the sampling hole is vacated, which is convenient for the subsequent cement to fall into the sampling barrel. Repeating this process can ensure the sampling quantity. Barrier rings are set on both sides of the sampling hole to block the sample cement and prevent the sample cement from moving between the sleeve and the sampling barrel. Ball bearings are set on the outside of the barrier ring to improve the smoothness of the sampling barrel when rotating relative to the sleeve. The setting of the observation window is convenient for the staff to observe the situation in the sampling barrel.

Under the rotation of the spiral disk, the cement sample entering the sampling barrel is driven by the spiral disk to move to the rear of the sampling barrel, so that the space at the sampling hole is vacated, which is convenient for the subsequent cement to fall into the sampling barrel. Repeating in this way can ensure the amount of sampling, and it can be more adapted to the scene with a larger sampling amount, and it is more practical.
[0019] 2. The bagged cement sampler can block the sample cement by setting barrier rings on both sides of the sampling hole to prevent the sample cement from moving between the sleeve and the sampling tube. Ball bearings are set on the outside of the barrier ring to improve the smoothness of the sampling tube when rotating relative to the sleeve. The setting of the observation window is convenient for the staff to observe the situation in the sampling tube.
