In related technologies, the cement sampling device is a sampling cylinder, and a sampling groove is provided at the top of the sampling cylinder. When the staff samples the cement, the sampling cylinder is inserted into the cement to be sampled, and the cement falls into the sampling cylinder from the sampling groove under the action of gravity. Then, the staff pulls out the sampling cylinder from the cement to be sampled, and the sampling of the cement is completed.
[0003] A Chinese patent with the publication number of "CN219870404U" discloses a sampling device for cement detection, which includes: a sampling cylinder with one end closed and the other end open; a sampling rod with one end extending into the opening of the sampling cylinder and fixed to the inner wall of the sampling cylinder; a baffle plate slidably connected to the sampling rod and sliding close to or away from the sampling cylinder, and the outer side wall of the baffle plate can be detachably attached to the inner side wall of the sampling cylinder.
[0004] However, there are still some deficiencies in this device. Since it is necessary to sample cement at different depths by inserting it into the cement, after sampling is completed, the user needs to pull out the entire device from the cement and then take out the cement in the device. Firstly, it is not conducive for the user to sample the cement sample. Secondly, it will also cause a vacancy at the sampling point of the cement, thereby affecting the later firmness of the cement. Content of the Utility Model

The bottom end of the pull rod protrudes from the bottom end of the sampling rod through the material passing hole. A stop block is fixedly connected to the bottom end of the pull rod, and the position of the stop block corresponds to the position of the material passing hole. A limit plate is threadedly connected to the outer wall of the sleeve, and a handle is fixedly connected to the outer wall of the sleeve.
[0008] As a preferred technical solution, a fixing block is fixedly connected to the top end of the limit plate. One side of the fixing block is in contact with the outer wall of the sleeve. A screw hole is opened on the other side of the fixing block. A bolt is threadedly connected inside the screw hole. One side of the bolt is threadedly connected to the inside of the sleeve through the screw hole. The limit plate is threadedly connected to the outer wall of the sleeve through the fixing block, screw hole and bolt.
[0009] As a preferred technical solution, a groove is opened at the bottom end of the limit plate. A floating foam is fixedly connected inside the groove. The floating foam covers the inside of the groove, and the bottom end of the floating foam protrudes two centimeters from the groove.
[0010] As a preferred technical solution, a sealing ring is fixedly connected to the bottom end of the limit plate. The sealing ring is located inside and close to the floating foam, and the inside of the sealing ring is in contact with the outer wall of the sleeve.
[0011] As a preferred technical solution, a collection box is slidably connected to the outer wall of the sampling rod. The support plate is located at the top end close to the collection box. A partition is slidably connected to the inner wall of the collection box. A second chute matching the partition is opened on the inner wall of the collection box. The partition is slidably connected to the inner wall of the collection box through the second chute.
[0012] As a preferred technical solution, a first chute is opened on the outer wall of the sampling rod. A connection hole matching the sampling rod is opened at the top end of the collection box. A slider matching the first chute is fixedly connected to the inner wall of the connection hole. The slider is slidably connected inside the first chute. The collection box is slidably connected to the outer wall of the sampling rod through the slider and the first chute.
[0013] As a preferred technical solution, an anti-corrosion layer is coated on the outer wall of the sampling rod. The thickness of the anti-corrosion layer on the outer wall of the sampling rod is one centimeter, and the anti-corrosion layer on the outer wall of the sampling rod covers the sampling rod.
[0014] In summary, the present utility model mainly has the following beneficial effects:
[0015] First, during use, to facilitate sampling of cement at different depths, the user can rotate the sampling rod in advance. Under the mutual cooperation of the external thread and the internal thread, the length of the sampling rod at the bottom end of the sleeve can be adjusted. After the adjustment is completed, the sampling rod is directly inserted into the cement. At this time, the pull rod and the block will also be sent into the cement together. Its limiting plate can limit the position of the sleeve, preventing the entire sleeve from sinking into the cement. Affected by the pressure, the through-hole will be filled with cement at different depths. When it is necessary to take out the cement, the pull rod is pulled through the convex block, and the block enters the through-hole, and then the cement in the through-hole can be directly pulled out to the top end of the sampling rod. Therefore, the purpose of facilitating the sampling of cement can be achieved. After the cement sampling is completed, the user can also fill the lacking position of the cement through the through-hole, thereby solving the problem that affects the later firmness of the cement;
[0016] Second, due to the existence of the collection box, when the cement is pulled out through the through-hole, the collection box can catch the falling cement. Since the depths of the cement samples overflowing at different stages are different, the user can slide the partition through the second chute. The sliding of the three partitions can divide the inner space of the collection box into three small spaces, which is conducive to the user to divide the cement samples at different depths. The mutual cooperation of the first chute and the slider is conducive to the user to directly disassemble the collection box later, which is more conducive to the user to accurately detect the cement samples later.

Under the mutual cooperation of the external thread 4 and the internal thread 2, the length of the sampling rod 3 at the bottom end of the sleeve 1 can be adjusted. After the adjustment is completed, the sampling rod 3 is directly inserted into the cement. At this time, the pull rod 9 and the stop block 10 will also be sent into the cement together. The limiting plate 17 can limit the position of the sleeve 1, and can prevent the entire sleeve 1 from sinking into the cement. Affected by the pressure, the through-hole 5 will be filled with cement at different depths. When it is necessary to take out the cement, the pull rod 9 is pulled through the convex block 8, and the stop block 10 enters the through-hole 5, and then the cement in the through-hole 5 can be directly pulled out to the top end of the sampling rod 3. Therefore, the purpose of convenient sampling of cement can be achieved. When the cement sampling is completed, the user can also fill the lacking position of the cement through the through-hole 5, and then the problem affecting the later firmness of the cement can also be solved.

[0030] Principle of use and advantages: When in use, to facilitate sampling of cement at different depths, the user can rotate the sampling rod 3 in advance. Under the mutual cooperation of the external thread 4 and the internal thread 2, the length of the sampling rod 3 at the bottom end of the sleeve 1 can be adjusted. After the adjustment is completed, the sampling rod 3 is directly inserted into the cement. At this time, the pull rod 9 and the stopper 10 will also be sent into the cement together. Its limit plate 17 can limit the position of the sleeve 1, and can prevent the entire sleeve 1 from sinking into the cement. Affected by the pressure, the through-hole 5 will be filled with cement at different depths. When it is necessary to take out the cement, the pull rod 9 is pulled through the convex block 8, and the stopper 10 enters the through-hole 5, and then the cement in the through-hole 5 can be directly pulled out to the top end of the sampling rod 3. Therefore, the purpose of facilitating sampling of cement can be achieved. After the cement sampling is completed, the user can also fill the lacking position of the cement through the through-hole 5, and then the problem affecting the later firmness of the cement can also be solved. Due to the existence of the bolt 20, the screwing of the bolt 20 can effectively fix the position of the limit plate 17 and prevent the limit plate 17 from shifting. When it is necessary to disassemble the limit plate 17, just screw out the bolt 20 from the screw hole 19, which is also conducive to the user's later maintenance of the limit plate 17. Due to the existence of the floating foam 23, the buoyancy at the bottom end of the limit plate 17 can be effectively increased, and the stability of the position placement of the limit plate 17 can be improved secondly to prevent the limit plate 17 from sinking into the cement. Due to the existence of the sealing ring 24, the connection point between the limit plate 17 and the sleeve 1 can be sealed, and the cement can be effectively prevented from flowing into the connection point between the two. Due to the existence of the collection box 12, when the cement is pulled out through the through-hole 5, the collection box 12 can catch the falling cement. Since the depths of the cement samples overflowing at different stages are different, the user can slide the partition plate 16 through the second chute 15. The sliding of the three partition plates 16 can divide the inner space of the collection box 12 into three small spaces, which is conducive to the user's division of the cement samples at different depths. The mutual cooperation of the first chute 11 and the slider 14 is conducive to the user's later direct disassembly of the collection box 12, which is more conducive to the user's later accurate detection of the cement samples.
