Description
Technical Field
[0001] This utility model relates to the field of cement slurry technology, and in particular to a cement testing and sampling device. Background Technology
[0002] Cement is a powdered hydraulic inorganic binder that forms a paste when mixed with water. It can harden in air or water and can firmly bind materials such as sand and stone together. After the cement is mixed according to the specified proportions, it needs to be sampled and tested before leaving the factory.
[0003] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: Existing sampling devices mostly involve manually scooping cement slurry into a container using tools such as spoons. Subsequently, staff monitor the cement inside the container, but during the process of sending the container for monitoring, the cement is easily caused to solidify due to prolonged contact with air. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides a cement testing and sampling device.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cement testing and sampling device, comprising a hollow sampling tube, a sampling head installed on the side wall of the sampling tube, a sealing cap installed at the end of the sampling tube away from the sampling head, a sliding plate slidably disposed inside the sampling tube, a rubber pad fixedly disposed on the side wall of the sliding plate, and the sampling head and the sampling tube communicating with each other.
[0006] By adopting the above technical solution, when workers need to take samples of cement, they need to insert the sampling head into the concrete mortar. Then, the workers slide the sliding plate upwards, causing the rubber pad to slide upwards with the sliding plate, thereby drawing the concrete mortar into the sampling tube. During this process, the sampling tube has a low probability of contact with the outside air due to the sealing cap, thus reducing the probability of the concrete mortar solidifying.
[0007] Furthermore, a bolt is threaded through the side wall of the sealing cover, a rotating groove is formed on the side wall of the slide plate away from the rubber pad, an annular groove is formed on the inner wall of the rotating groove, the bolt is rotatably connected to the rotating groove, an annular block is rotatably arranged in the annular groove, and the bolt and the annular block are fixed to each other.
[0008] By adopting the above technical solution, when the sliding plate needs to be slid, the operator needs to rotate the bolt, which moves the bolt upward, causing the sliding plate to slide upward under the action of the bolt. This, in turn, causes the rubber pad to move upward under the action of the sliding plate, thereby reducing the difficulty for the operator to slide the sliding plate and thus reducing the difficulty of the operator's work. During this process, the ring block rotates synchronously with the bolt under the action of the bolt, which reduces the probability of the bolt and the sliding plate separating from each other, thereby improving the stability of the device.
[0009] Furthermore, two mounting grooves are provided on the inner wall of the sampling tube at the end away from the sampling head, and rotating grooves are provided on the two opposite inner walls of the mounting grooves. Two placement grooves are provided on the outer wall of the sealing cover. A rotating rod is rotatably installed in the rotating groove, and a mounting block is fixedly installed on the side wall of two adjacent rotating rods that are close to each other. The mounting block matches the placement groove.
[0010] By adopting the above technical solution, when workers need to clean the sampling tube, they need to pull the bolt upwards, causing the sealing cap to slide upwards under the action of the bolt. During this process, the mounting block rotates under the action of the sealing cap, which in turn causes the rotating rod to rotate under the action of the sealing cap. The mounting block then rotates into the mounting groove under the action of the sealing cap, thus removing its obstruction of the sealing cap and separating it from the sampling tube. After cleaning, workers then install the sealing cap. At this point, the mounting groove and the placement groove are aligned. Workers need to rotate the mounting block in the opposite direction, so that both ends of the mounting block are in the mounting groove and placement groove respectively. This limits the sealing cap's position, allowing it to be installed into the sampling tube, thus reducing the difficulty of cleaning the sampling tube.
[0011] Furthermore, a reset groove is provided on the inner wall of the rotating groove, and a torsion spring is fixedly provided on the inner wall of the reset groove. The other end of the torsion spring is fixedly provided on the side wall of the rotating rod.
[0012] By adopting the above technical solution, when the mounting slot and the placement slot are aligned, the mounting block and the rotating rod rotate in opposite directions under the action of the torsion spring, thereby reducing the difficulty for workers to rotate the mounting block and thus reducing the difficulty of their work.
[0013] Furthermore, a first receiving groove is provided on the outer wall of the sealing cap, and a second receiving groove is provided on the inner wall of the sampling tube. A sealing gasket is installed in both the first and second receiving grooves.
[0014] By adopting the above technical solution, the sealing gasket improves the sealing performance of the device, thereby reducing the probability of concrete mortar solidification inside the sampling tube.
[0015] Furthermore, a sealing block is installed on the sampling head, and the sealing block is made of rubber.
[0016] By adopting the above technical solution, after the staff has taken the sample, the staff needs to install the sealing block into the sampling tube, which further reduces the probability of the concrete mortar in the sampling tube solidifying.
[0017] Furthermore, a functional handle is installed on the side wall of the bolt.
[0018] By adopting the above technical solution, the functional handle reduces the difficulty for workers to turn the bolts, thereby reducing the difficulty of their work.
[0019] Furthermore, both ends of the mounting block are rounded.
[0020] By adopting the above technical solution, the rounded corners reduce the probability of collisions when the mounting block rotates, thereby improving the stability of the device.
[0021] In summary, this utility model has the following beneficial effects:
[0022] 1. In this application, when workers need to take samples of cement, they need to insert the sampling head into the concrete mortar. Then, the workers slide the sliding plate upwards, causing the rubber pad to slide upwards with the sliding plate, thereby drawing the concrete mortar into the sampling tube. During this process, the sampling tube has a low probability of contact with the outside air due to the sealing cap, thus reducing the probability of the concrete mortar solidifying.
[0023] 2. In this application, when the sliding plate needs to be slid, the operator needs to turn the bolt, which moves the bolt upward, causing the sliding plate to slide upward under the action of the bolt, and then the rubber pad to move upward under the action of the sliding plate. This reduces the difficulty for the operator to slide the sliding plate and thus reduces the difficulty of the operator's work. During this process, the ring block rotates synchronously with the bolt under the action of the bolt. The ring block reduces the probability of the bolt and the sliding plate separating from each other, thereby improving the stability of the device.
[0024] 3. In this application, when the worker needs to clean the sampling tube, the worker needs to pull the bolt upwards, causing the sealing cap to slide upwards under the action of the bolt. During this process, the mounting block rotates under the action of the sealing cap, which in turn causes the rotating rod to rotate under the action of the sealing cap. During this process, the mounting block rotates into the mounting groove under the action of the sealing cap, thereby removing the obstruction of the sealing cap by the mounting block and separating the sealing cap from the sampling tube. Subsequently, after cleaning, the worker installs the sealing cap. At this time, the mounting groove and the placement groove are aligned. The worker needs to rotate the mounting block in the opposite direction, so that both ends of the mounting block are in the mounting groove and the placement groove respectively, thereby limiting the sealing cap by the mounting block and installing the sealing cap into the sampling tube, thus reducing the difficulty of cleaning the sampling tube for the worker.

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0031] like Figure 1-4As shown in the illustration, this application discloses a cement testing sampling device, including a sampling tube 1, a sampling head 11, a sealing cap 12, a sliding plate 13, a rubber pad 14, a bolt 2, an annular block 21, a rotating rod 4, and a mounting block 41. The sampling tube 1 has a cylindrical structure, and the sampling head 11 is installed on the side wall of the sampling tube 1, communicating with the sampling tube 1. The sealing cap 12 is installed at the end of the sampling tube 1 away from the sampling head 11. The sliding plate 13 has a cylindrical structure and is slidably disposed inside the sampling tube 1. The rubber pad 14 is fixedly disposed on the side wall of the sliding plate 13.
[0032] When workers need to take samples of cement, they need to insert the sampling head 11 into the concrete mortar. Then, the workers slide the sliding plate 13 upwards, causing the rubber pad 14 to slide upwards along with the sliding plate 13, thereby drawing the concrete mortar into the sampling tube 1. During this process, the sampling tube 1 has a low probability of contact with the outside air due to the sealing cap 12, thus reducing the probability of the concrete mortar solidifying.
[0033] A rotating groove 3 is formed on the side wall of the slide plate 13 away from the rubber pad 14, and an annular groove 31 is formed on the inner wall of the rotating groove 3. The bolt 2 is threaded through and set on the side wall of the sealing cover 12, and the bolt 2 is rotatably connected to the rotating groove 3. The annular block 21 has a circular structure, and the annular block 21 is rotatably set in the annular groove 31, and the bolt 2 is fixed to the annular block 21.
[0034] When the sliding plate 13 needs to be slid, the operator needs to rotate the bolt 2, which moves the bolt 2 upward, causing the sliding plate 13 to slide upward under the action of the bolt 2. This, in turn, causes the rubber pad 14 to move upward under the action of the sliding plate 13, thereby reducing the difficulty for the operator to slide the sliding plate 13 and thus reducing the difficulty of the operator's work. During this process, the ring block 21 rotates synchronously with the bolt 2 under the action of the bolt 2. The ring block 21 reduces the probability of the bolt 2 and the sliding plate 13 separating from each other, thereby improving the stability of the device.
[0035] Two mounting grooves 32 are formed on the inner wall of the sampling tube 1 at the end away from the sampling head 11. Rotation grooves 33 are formed on the two opposite inner walls of the mounting grooves 32. Two placement grooves 34 are formed on the outer wall of the sealing cover 12. The rotating rod 4 is a round rod structure and is rotatably mounted in the rotation groove 33. The mounting block 41 is fixedly mounted on the side wall of the two rotating rods 4 that are close to each other, and the mounting block 41 matches the placement groove 34.
[0036] When cleaning sampling tube 1, the worker pulls bolt 2 upwards, causing the sealing cap 12 to slide upwards. During this process, mounting block 41 rotates under the action of sealing cap 12, causing rotating rod 4 to rotate as well. Mounting block 41 then rotates into mounting groove 32, removing its obstruction of sealing cap 12 and separating it from sampling tube 1. After cleaning, the worker installs sealing cap 12. With mounting groove 32 and placement groove 34 aligned, the worker rotates mounting block 41 in the opposite direction, positioning both ends of mounting block 41 within mounting groove 32 and placement groove 34 respectively. This limits the sealing cap 12, allowing it to be installed into sampling tube 1, thus reducing the difficulty of cleaning sampling tube 1.
[0037] To reduce the difficulty of the work for the workers, a reset groove 35 is provided on the inner wall of the rotating groove 33. A torsion spring 5 is fixedly installed on the inner wall of the reset groove 35, and the other end of the torsion spring 5 is fixedly installed on the side wall of the rotating rod 4. When the mounting groove 32 and the placement groove 34 are aligned, the mounting block 41 and the rotating rod 4 rotate in opposite directions under the action of the torsion spring 5, thereby reducing the difficulty for the workers to rotate the mounting block 41 and thus reducing the difficulty of the workers' work.
[0038] To reduce the probability of concrete mortar solidifying inside the sampling tube 1, a first receiving groove 36 is provided on the outer wall of the sealing cap 12, and a second receiving groove 37 is provided on the inner wall of the sampling tube 1. A sealing gasket 6 is installed in both the first receiving groove 36 and the second receiving groove 37. The sealing gasket 6 improves the sealing performance of the device, thereby reducing the probability of concrete mortar solidifying inside the sampling tube 1.
[0039] To reduce the probability of concrete mortar solidifying inside sampling tube 1, a sealing block 7 made of rubber is installed on sampling head 11. After sampling, the staff needs to install the sealing block 7 into sampling tube 1, thereby further reducing the probability of concrete mortar solidifying inside sampling tube 1.
[0040] To reduce the difficulty of the work for the workers, a functional handle 8 is installed on the side wall of bolt 2. The functional handle 8 reduces the difficulty for the workers to turn bolt 2, thereby reducing the difficulty of the work for the workers.
[0041] To improve the stability of the device, rounded corners 9 are provided at both ends of the mounting block 41. The rounded corners 9 reduce the probability of collision when the mounting block 41 rotates, thereby improving the stability of the device.
[0042] The working principle of the cement testing and sampling device in this embodiment is as follows: When the staff needs to take a sample of the cement, the staff needs to insert the sampling head 11 into the concrete mortar. Then, the staff slides the sliding plate 13 upward, and the rubber pad 14 slides upward with the sliding plate 13 under the action of the sliding plate 13, so that the concrete mortar is sucked into the sampling tube 1. During this process, the sampling tube 1 has a small probability of contact with the outside air under the action of the sealing cap 12, thereby reducing the probability of the concrete mortar solidifying.
[0043] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected by this utility model. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
