Description

Technical Field

[0001] This utility model belongs to the field of cement sampling technology, and specifically relates to a sampling device for testing the proportion of special cement. Background Technology

[0002] Cement is a common building material. It is a powdery substance mainly composed of raw materials such as limestone, clay, gypsum, and silicates. It reacts with water to form a hard texture. Cement is usually mass-produced. Before it is put into use, it needs to be sampled and tested. Special cement is different from general cement. It has certain unique properties and is suitable for specific uses or can play a special role.

[0003] A search revealed that in the prior art, Chinese Patent Publication No. CN219589999U, authorized on August 25, 2023, discloses a cement sampling tool, including a sampling tube. A tubular handle is installed on the rear half of the sampling tube. A sleeve and a telescopic spring are movably inserted inside the handle. The sleeve and telescopic spring are fitted onto the outside of the sampling tube, with the telescopic spring providing forward support to the sleeve. The sleeve extends into the front half of the sampling tube, and its inner wall is in contact with the outer wall of the sampling tube. In this embodiment, the cement inside the sampling tube will not spill outwards.

[0004] However, the device still has the following drawbacks: the above embodiment does not have the effect of continuous multiple sampling. If it is necessary to sample cement from different locations or types, multiple sets of equipment need to be carried or the equipment needs to be manually cleaned before use, which reduces the flexibility of the equipment and consumes a lot of time.

A storage groove 14 is provided on the side wall of the mounting groove 5 near the sampling head 2. Two sets of first electric push rods 15 are symmetrically installed in the storage groove 14. Both sets of first electric push rods 15 are electrically connected to the control panel 10. A push plate 16 is installed on the output end of the two sets of first electric push rods 15. A protective pad 17 is installed on the side wall of the push plate 16 away from the first electric push rod 15.

[0028] For example, such as Figure 2 and Figure 4 As shown, a number of first fixing components 18 are installed in a ring array on the outer wall of the mounting rod 12. The first fixing components 18 slide against the inner wall of the mounting box 1 near the sampling head 2. A number of sampling tubes 23 are arranged in a ring array inside the mounting box 1.

[0029] The first fixing component 18 includes a first connecting block 181. One end of the first connecting block 181 is mounted on the outer wall of the mounting rod 12, and the other end of the first connecting block 181 is mounted on a first mounting plate 182. A first mounting cavity 183 is formed on the first mounting plate 182, and a second soft pad 184 is disposed in the first mounting cavity 183.

[0030] For example, such as Figure 4 , Figure 5 and Figure 6As shown, the outer wall of the mounting rod 12 is provided with several sets of movable slots 19 in a circular array. Each set of movable slots 19 has a set of movable blocks 20 sliding in it. Each set of movable blocks 20 has a set of springs 21 installed at one end. The springs 21 are located at the end of the movable blocks 20 that is close to the mounting groove 5. The other end of the springs 21 is installed on the inner wall of the movable slot 19. The mounting rod 12 is provided with several sets of second fixing components 22 in a circular array. One end of each set of movable blocks 20 passes through one set of movable slots 19 and is installed on one set of second fixing components 22.

[0031] The second fixing component 22 includes a second connecting block 221. A second mounting plate 222 is installed at one end of the second connecting block 221. A second mounting cavity 223 is formed on the second mounting plate 222. Two sets of empty slots 224 are symmetrically formed in the second mounting plate 222. Both sets of empty slots 224 are connected to the second mounting cavity 223. A set of second electric push rods 225 is installed in each set of empty slots 224. A set of clamping plates 226 is installed on the output end of each set of second electric push rods 225. A control button 227 is installed on the second mounting plate 222. Both sets of second electric push rods 225 are electrically connected to the control button 227.

[0032] Working principle: The motor 11 and the first electric push rod 15 are started by the control panel 10. The first electric push rod 15 drives the push plate 16 and the protective pad 17 to move, while pushing the sampling tube 23 and the second fixing component 22 to move. The second fixing component 22 drives the moving block 20 to move, while stretching the sampling tube 23. The sampling tube 23 moves through the cavity 3 to collect material, and the material enters the sampling tube 23.

[0033] The first electric push rod 15 drives the protective pad 17 to return to its original position. The spring 21 pulls the second fixing component 22 to move and return to its original position, while simultaneously driving the sampling tube 23 to return to its original position. The first soft pad 4 scrapes off the lime on the outer wall of the sampling tube 23 to prevent cross-contamination and ensure the purity of the sample and the accuracy of the test results.

[0034] The motor 11 drives the mounting rod 12 to rotate, which in turn drives the sampling tube 23 to rotate. The sampling tube 23 that has completed sampling is replaced with the sampling tube 23 that has not yet been sampled. The first electric push rod 15 is started again to perform the next sampling. Sampling can be performed continuously multiple times.

[0035] After the sampling number is reached, turn the end of the sampling head 2 away from the installation box 1 upwards, pull the fixing block 9 to move the installation block 7, and the installation block 7 will pull the card block 8 out of the card slot 6 at the same time, and pull the installation rod 12 out of the rotating slot 13 and the installation box 1. Press the control button 227, the second electric push rod 225 will start and drive the clamping plate 226 to move away from the sampling tube 23, and move the sampling tube 23 out of the second installation cavity 223 and the first installation cavity 183.

[0036] The new sampling tube 23 is inserted into the first mounting cavity 183 and then into the second mounting cavity 223. The control button 227 is pressed again, and the second electric push rod 225 drives the clamping plate 226 to move and fit against the outer wall of the sampling tube 23 for fixation. After the replacement is completed, the mounting block 7 is placed in the mounting groove 5 so that the locking block 8 is moved and locked in the locking groove 6.

[0037] The first electric push rod 15 moves the push plate 16 and the protective pad 17, pushing the sampling tube 23 through the cavity 3. The material enters the sampling tube 23. The first electric push rod 15 returns to its original position, while the sampling tube 23 returns to its original position. The motor 11 drives the mounting rod 12 to rotate, while the sampling tube 23 rotates. The sampling tube 23 that has completed sampling is replaced with the sampling tube 23 that has not been sampled. The first electric push rod 15 is started again to perform the next sampling. Sampling can be performed continuously multiple times, which improves the flexibility of the equipment and saves time and effort.

[0038] The second electric push rod 225 is controlled by the control button 227 to move the clamping plate 226, clamping and releasing the sampling tube 23, moving the sampling tube 23 for installation and removal, which facilitates replacement and improves both convenience and practicality.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
