[0003] For example, Chinese patent document (CN108375487A) describes a cement sampling and testing device, which includes a sampling cylinder, a sampling groove, and a drive rod. The sampling cylinder is a cylindrical body closed at one end, with several mounting holes evenly distributed on its side wall. A sampling groove, which is hinged to the mounting hole and can be screwed into or out of the sampling cylinder around the hinge axis, is a wedge-shaped groove with an outer wall that corresponds to the arc-shaped surface of the sampling cylinder. This invention features a simple structure, convenient use, and ingenious design. The sampling cylinder is designed with a conical bottom for easy insertion into the cement. By inserting the drive rod downward into the sampling cylinder, the sampling groove can be screwed out of the sampling cylinder around the hinge axis. Rotating the sampling cylinder allows sampling from sampling grooves at different depths. The design of sampling grooves at different heights ensures different sampling depths. Each sampling tube is independent and can test cement at different depths separately. However, during use, when the cement raw material clumps, it can affect the quality of the sampling and subsequent testing. Therefore, improvements are needed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-4 The present invention provides a technical solution: a cement material sampling device, including a sampling cylinder 1, a sampling component 2 is provided inside the sampling cylinder 1, the sampling component 2 includes a vertical plate 202, and auxiliary sampling components 3 are provided on both sides of the vertical plate 202.

[0033] The auxiliary sampling component 3 includes multiple third cone blocks 301 fixedly connected to the vertical plate 202. A roller 302 is provided at the top of the vertical plate 202. A fixing rod 303 is fixedly connected to the side of the roller 302 away from the vertical plate 202. A fourth cone block 305 is fixedly connected to the other end of the fixing rod 303. A fifth cone block 306 is attached to one side of the bottom of the fourth cone block 305. Two guide rods 310 are symmetrically fixedly connected to both sides of the bottom of the fifth cone block 306. A vibration guide head 311 is fixedly connected to the bottom end of the guide rod 310. The multiple third cone blocks 301 are linearly distributed outside the vertical plate 202, and the multiple third cone blocks 301 increase in size from top to bottom. The larger the roller 302 is, the further away from the fixed rod 303 it is from the vertical plate 202. The fixed rod 303 is fitted with a second spring 304 on its outer periphery. The two sides of the second spring 304 are fixedly connected to one side of the roller 302 and the inner wall of the sampling cylinder 1, respectively. The outer periphery of multiple guide rods 310 is fixedly connected to the same horizontal plate 307. The bottom center of the horizontal plate 307 is fixedly connected to a third spring 308. The bottom of the third spring 308 is fixedly connected to a fixed plate 309. One side of the fixed plate 309 is fixedly connected to the inner wall of the sampling cylinder 1. The fixed plate 309 has symmetrical circular through holes on both sides inside. The guide rods 310 are slidably connected inside the circular through holes.

[0034] Detailed Implementation: The sampling cylinder 1 is fixed to the external drive unit. The external drive unit drives the sampling cylinder 1 into the cement material to be sampled, causing the electric push rod 201 to move the vertical plate 202 and the first cone block 203 upward. The first spring 207 will drive the sampling box 206 to reset. Then, as needed, the electric push rod 201 will drive the vertical plate 202 to continue moving upward. Under the action of the vertical plate 202, the third cone block 301 will move upward, causing the roller 302 to squeeze the second spring 304. At this time, the roller... 302 will drive the fixed rod 303 and the fourth cone block 305 to move, causing the fifth cone block 306 to drive the horizontal plate 307, guide rod 310 and guide head 311 to move downward. The guide head 311 will vibrate and crush the cement material inside the sampling box 206. Vibration can mechanically crush the loose lumps captured during the sampling process and improve the uniformity of the sample. By making the multiple third cone blocks 301 larger and larger from top to bottom, the vibration force of the guide head 311 is adjusted to suit the material vibration needs of different situations, thereby ensuring the applicability of the device.

[0035] An electric push rod 201 is fixedly connected to the top of the vertical plate 202. The top of the electric push rod 201 is fixedly connected to the inner wall of the sampling cylinder 1. Sampling ports are opened on both sides of the inside of the sampling cylinder 1. A first cone block 203 is fixedly connected to both sides of the bottom of the vertical plate 202. A second cone block 204 is attached to the other side of the first cone block 203. A connecting rod 205 is fixedly connected to the side of the second cone block 204 away from the first cone block 203. A sampling box 206 is fixedly connected to the other end of the connecting rod 205. The sampling box 206 is slidably sealed inside the sampling port. A first spring 207 is sleeved on the outer periphery of the connecting rod 205. The two sides of the first spring 207 are fixedly connected to one side of the second cone block 204 and the inner wall of the sampling cylinder 1, respectively.

[0036] Detailed implementation: The electric push rod 201 drives the vertical plate 202 and the first cone block 203 to move downwards, so that the first cone block 203 squeezes the second cone block 204, the connecting rod 205 and the first spring 207, causing the sampling box 206 to move away from the outside of the sampling cylinder 1. The sampling box 206 samples the external cement material. When closed, the sampling box 206 can form a relatively sealed space, protecting the sample from the influence of environmental humidity during the removal process, thereby ensuring the portability of the cement material during the sampling process.

[0037] Working principle: In use, the sampling cylinder 1 is fixed to the external drive unit. The external drive unit drives the sampling cylinder 1 into the cement material to be sampled. Then, the electric push rod 201 drives the vertical plate 202 and the first cone block 203 to move downwards, causing the first cone block 203 to squeeze the second cone block 204, the connecting rod 205, and the first spring 207, causing the sampling box 206 to move away from the outside of the sampling cylinder 1. The sampling box 206 samples the external cement material. Then, the electric push rod 201 drives the vertical plate 202 and the first cone block 203 to move upwards. Spring 207 will drive sampling box 206 to reset. Then, according to actual needs, electric push rod 201 will drive vertical plate 202 to continue to move upward. Under the action of vertical plate 202, the third cone block 301 will move upward, so that roller 302 will squeeze the second spring 304. At this time, roller 302 will drive fixed rod 303 and fourth cone block 305 to move, so that fifth cone block 306 will drive horizontal plate 307, guide rod 310 and guide head 311 to move downward. The guide head 311 will vibrate and crush the cement material inside sampling box 206, which is convenient to use.
