Furthermore, the sieve must be removed each time it is cleaned, making the operation cumbersome, time-consuming, and labor-intensive.

[0003] An inspection device for cement samples is proposed to address the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a testing device for cement samples, in order to solve the problems mentioned in the background art. In the current prior art, the commonly used device for cement samples is the cement fineness negative pressure sieve analyzer. However, after a period of use, the screen of the cement fineness negative pressure sieve analyzer is easily clogged by cement powder, which affects the sieving efficiency and accuracy. Moreover, the screen needs to be removed every time it is cleaned, which is troublesome, time-consuming and labor-intensive.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a testing device for cement samples, comprising a box body, wherein a cylinder is fixedly installed in the middle of the top surface of the box body; Several fixing screws are connected through both sides of the box body. A rubber gasket is connected through one side of the fixing screw. An anti-loosening nut is attached to one side of the rubber gasket. The anti-loosening nut is threaded to the fixing screw. A sliding groove is opened in the middle of the inside of the box body. A slider is slidably connected inside the sliding groove. A collection box is fixedly connected to the top surface of the slider. Also includes: A connecting plate is fixedly connected to one side surface of the cylinder output end through the housing, and quick-release components are symmetrically arranged on the top surface of the connecting plate; The quick-release assembly includes a connecting bracket that is fixedly connected to the connecting plate; A connecting sleeve is fixedly installed in the middle of the top surface of the connecting frame.

[0006] Preferably, a screw is connected through the inside of the connecting sleeve, a bearing seat is rotatably connected to the bottom surface of the screw, and a sliding plate is fixedly connected to the bottom surface of the bearing seat.

[0007] Preferably, a snap-fit ​​rod is fixedly connected to the middle of the bottom surface of the skateboard, the snap-fit ​​rod is connected through the connecting sleeve, and the skateboard is slidably connected to the connecting sleeve.

[0008] Preferably, the inner sides of the box are symmetrically provided with sliding grooves, and a sliding block is slidably connected inside the sliding groove. A screen is fixedly connected to the surface of the sliding block away from the sliding groove.

[0009] Preferably, a connecting plate is fixedly connected to the cylinder output end through one side surface of the housing.

[0010] Preferably, a threaded groove is formed in the middle of one side surface of the sliding block, and the threaded groove is threadedly connected to the fixing screw.

[0011] Preferably, the connecting plate has connecting grooves on both sides inside, a T-shaped plate is slidably connected inside the connecting groove, a drain plate is fixedly connected to the bottom surface of the T-shaped plate, and a snap-fit ​​groove is formed in the middle of the top surface of the T-shaped plate, which is engaged with a snap-fit ​​post.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This testing device for cement samples, through the cooperation of a connecting plate, connecting groove, T-shaped plate, unblocking plate, snap-fit ​​groove, and quick-release assembly, allows for quick-release of the unblocking plate, thereby enabling unblocking of sieves with different aperture sizes and reducing the frequency of sieve clogging. Simultaneously, the inclusion of a fixing screw, rubber gasket, and anti-loosening nut allows for sieve replacement, thus meeting the testing requirements for cement samples of varying fineness. The specific details are as follows: 1. By setting up connecting plates, connecting grooves, T-plates, unblocking plates, snap-fit ​​grooves, and quick-release components, different unblocking plates are required when unblocking screens with different aperture sizes. This necessitates replacing the unblocking plates. When replacing the unblocking plate, rotating the screw, which has a threaded connection with the connecting sleeve, allows the screw to move during rotation. Simultaneously, the screw has a rotatable connection with the bearing housing, ensuring that the screw's rotation does not drive the bearing housing, sliding plate, or snap-fit ​​mechanism. The rotation of the column, and the movement of the screw under rotation, can drive the movement of the bearing seat, the sliding plate, and the snap-fit ​​column. This allows the drain plate to be disassembled and replaced by pulling it when the snap-fit ​​column separates from the snap-fit ​​groove. When installing the drain plate, the T-shaped plate is placed inside the connecting groove, and the drain plate is pushed into the housing completely. Then, the screw is rotated again, causing the bearing seat, the sliding plate, and the snap-fit ​​column to descend, so that the snap-fit ​​column engages with the snap-fit ​​groove, thus achieving quick disassembly of the drain plate. 2. When performing detailed testing of cement samples, the screen needs to be replaced by setting a fixing screw, rubber gasket, and anti-loosening nut. This is done by using a tool to rotate the anti-loosening nut to separate it from the fixing screw, then pulling the screen to complete the replacement. Similarly, when installing the screen, place the slider on the screen inside the groove, push the screen completely into the housing, screw the fixing screw into the threaded groove, then place the rubber gasket on the fixing screw, and finally thread the anti-loosening nut onto the fixing screw to complete the screen replacement and installation.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-6 This utility model provides a technical solution: a testing device for cement samples, including a box body 1, a cylinder 2 fixedly installed in the middle of the top surface of the box body 1; several fixing screws 3 are connected through the two side surfaces of the box body 1, a rubber gasket 4 is connected through one side of the surface of the fixing screw 3, an anti-loosening nut 5 is attached to one side of the surface of the rubber gasket 4, the anti-loosening nut 5 is threadedly connected to the fixing screw 3, a sliding groove 6 is opened in the middle of the interior of the box body 1, a slider 7 is slidably connected in the sliding groove 6, and a collection box 8 is fixedly connected to the top surface of the slider 7; it also includes: a connecting plate 12 fixedly connected to one side surface of the box body 1 through the output end of the cylinder 2, quick-release components 18 are symmetrically arranged on the top surface of the connecting plate 12; wherein, the quick-release component 18 includes a connecting frame 1801 fixedly connected to the connecting plate 12; wherein, a connecting sleeve 1802 is fixedly installed in the middle of the top surface of the connecting frame 1801, such as Figure 1-6 As shown, by setting the connection plate 12, connection groove 14, T-shaped plate 15, unblocking plate 16, snap-fit ​​groove 17 and quick-release assembly 18, the unblocking plate 16 can be quickly disassembled, thereby unblocking the screens 11 with different aperture sizes, thus reducing the frequency of clogging of the screens 11. At the same time, by setting the fixing screw 18033, rubber gasket 4 and anti-loosening nut 5, the screens 11 can be replaced, thereby meeting the requirements for testing cement samples with different fineness. Meanwhile, the cylinder 2 is electrically connected to the control end.

[0017] A screw 1803 is internally connected to the connecting sleeve 1802. A bearing seat 1804 is rotatably connected to the bottom surface of the screw 1803. A sliding plate 1805 is fixedly connected to the bottom surface of the bearing seat 1804. A snap-fit ​​rod 1806 is fixedly connected to the middle of the bottom surface of the sliding plate 1805. The snap-fit ​​rod 1806 is internally connected to the connecting sleeve 1802, and the sliding plate 1805 is slidably connected to the connecting sleeve 1802. Figure 5 , 6 As shown, when replacing the drain cleaning plate 16, the screw 1803 is rotated. The screw 1803 and the connecting sleeve 1802 are connected by a thread, which allows the screw 1803 to move when rotating. At the same time, the screw 1803 is connected to the bearing seat 1804, which means that the screw 1803 will not drive the bearing seat 1804, the sliding plate 1805, and the locking post to rotate when rotating. However, when the screw 1803 moves while rotating, it can drive the bearing seat 1804, the sliding plate 1805, and the locking post to move. Thus, when the locking post separates from the locking groove 17, the drain cleaning plate 16 can be disassembled and replaced by pulling it.

[0018] The interior of the housing 1 has symmetrical sliding grooves 9 on both sides. Sliding blocks 10 are slidably connected inside the sliding grooves 9. A screen 11 is fixedly connected to the surface of the sliding block 10 away from the sliding groove 9. A connecting plate 12 is fixedly connected to the side surface of the housing 1 through which the output end of the cylinder 2 passes. A threaded groove 13 is formed in the middle of one side surface of the sliding block 10, and the threaded groove 13 is threadedly connected to the fixing screw 3. Figure 2 , 3As shown, by setting the fixing screw 3, rubber gasket 4, and anti-loosening nut 5, when performing fine testing on cement samples, the screen 11 needs to be replaced. This can be done by using a tool to rotate the anti-loosening nut 5, separating it from the fixing screw 3, and then pulling the screen 11 to complete the replacement. Similarly, when installing the screen 11, the slider 7 on the screen 11 is placed inside the groove 6, and then the screen 11 is fully pushed into the housing 1. The fixing screw 3 is then screwed into the threaded groove 13, the rubber gasket 4 is fitted onto the fixing screw 3, and finally the anti-loosening nut 5 is screwed in. The screen 11 can be replaced and installed by connecting it to the fixing screw 3. The screen 11 is equipped with an ultrasonic device that uses high-frequency ultrasonic vibration to cause micro-vibration of the screen 11, preventing material particles from adhering to it and effectively solving the problem of screen 11 clogging. This is especially suitable for fine screening. The ultrasonic device is existing technology, and its working principle and power connection are the same as existing technologies. The ultrasonic transducer is bolted to the metal frame of the screen 11, transmitting the ultrasonic vibration to the entire screen surface through the frame, thus achieving the vibration purpose. The ultrasonic device model is Teledyne. The SeaBat T20-P provides excellent dust and water resistance. To prevent the screen 11 from loosening under vibration, a combination of anti-loosening nuts 5 and rubber washers 4 is used. The anti-loosening nuts 5 with anti-reverse grooves, along with the silicone rubber washers 4, eliminate the gap between the fixing screw 3 and the screen 11 and buffer the impact of vibration on the fixing screw 3, preventing loosening. At the same time, the screen 11 material with "high elastic modulus + high fatigue strength" is selected to improve the strength and service life of the screen 11. Before sliding the sliding block 10 and sliding groove 9 on the screen 11, the inside of the sliding groove 9 can be blown to reduce the accumulation of dust inside the sliding groove 9.

[0019] Connecting grooves 14 are provided on both sides of the inner side of the connecting plate 12. A T-shaped plate 15 is slidably connected inside the connecting grooves 14. A drain plate 16 is fixedly connected to the bottom surface of the T-shaped plate 15. A snap-fit ​​groove 17 is provided in the middle of the top surface of the T-shaped plate 15. The snap-fit ​​groove 17 is engaged with the snap-fit ​​post. Figure 4 As shown, when installing the drain cleaning plate 16, the T-shaped plate 15 is placed inside the connecting groove 14, and the drain cleaning plate 16 is pushed into the housing 1 completely. Then, the screw 1803 is rotated again, causing the screw 1803 to drive the bearing seat 1804, the sliding plate 1805 and the locking post to descend, so that the locking post engages with the locking groove 17, thereby achieving quick disassembly of the drain cleaning plate 16.

[0020] Working principle: Before using this testing device for cement samples, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 6 As shown, by first setting up the connecting plate 12, connecting groove 14, T-shaped plate 15, unblocking plate 16, snap-fit ​​groove 17, and quick-release assembly 18, different unblocking plates 16 are required when unblocking screens 11 with different aperture sizes. This necessitates replacing the unblocking plate 16. When replacing the unblocking plate 16, the screw 1803 is rotated. The screw 1803 and connecting sleeve 1802 are connected by a threaded rotation, allowing the screw 1803 to move during rotation. Simultaneously, the screw 1803 is rotatably connected to the bearing seat 1804, ensuring that the screw 1803 does not drive the bearing seat 1804 or the sliding plate 1802 during rotation. The rotation of 805 and the locking post, and the movement of the screw 1803 under rotation, can drive the movement of the bearing seat 1804, the sliding plate 1805 and the locking post. Thus, when the locking post is separated from the locking groove 17, the unblocking plate 16 can be disassembled and replaced by pulling it. When installing the unblocking plate 16, by placing the T-shaped plate 15 inside the connecting groove 14 and pushing the unblocking plate 16 into the housing 1 completely, the screw 1803 is rotated again, causing the screw 1803 to drive the bearing seat 1804, the sliding plate 1805 and the locking post to descend, so that the locking post engages with the locking groove 17, thereby achieving quick disassembly of the unblocking plate 16.

[0021] Secondly, by setting up the fixing screw 3, rubber gasket 4, and anti-loosening nut 5, when performing fine testing on cement samples, the screen 11 needs to be replaced. At this time, the anti-loosening nut 5 can be rotated with a tool to separate it from the fixing screw 3, and then the screen 11 can be pulled to complete the replacement of the screen 11. At the same time, when installing the screen 11, the slider 7 on the screen 11 is placed inside the slide groove 6, and then the screen 11 is fully pushed into the box 1. The fixing screw 3 is screwed into the threaded groove 13, and then the rubber gasket 4 is put on the fixing screw 3. Finally, the anti-loosening nut 5 is threaded onto the fixing screw 3 to complete the replacement and installation of the screen 11.

[0022] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
