A rotating rod 12 has multiple stirring blades 13 fixedly connected to its outer wall. The output end of the second motor 9 drives the first bevel gear 10 to rotate, and the second bevel gear 11 will rotate, causing the rotating rod 12 at the bottom of the second bevel gear 11 to rotate, which in turn drives the stirring blades 13 to rotate. A cement bucket 14 is set on the top front side of the bottom plate 1. The cement bucket 14 is placed on the bottom plate 1, and the stirring blades 13 stir the cement inside it. A fixing rod 15 is fixedly connected to the top of the connecting sleeve 8, and an extrusion plate 16 is fixedly connected to the top of the fixing rod 15. When the connecting sleeve 8 rotates, the fixing rod 15 and the extrusion plate 16 at its top will face downwards, and the telescopic rod 4 will retract, causing the extrusion plate 16 to extrude the cement inside the cement bucket 14 to test the strength of the cement. Clamping mechanisms 2 are set on the left and right sides of the top of the bottom plate 1 to clamp the cement bucket 14 and prevent it from moving during stirring.

[0041] Specifically, a fixed frame 3 is fixedly connected to the top rear side of the base plate 1. A telescopic rod 4 is fixed to the front end of the bottom inner side of the fixed frame 3, and a guide post 5 is fixed to the rear end of the bottom inner side of the fixed frame 3. When the telescopic rod 4 is activated, it will push the top moving block 6 to move up and down. Since the rear side of the moving block 6 can move up and down smoothly along the guide post 5, this ensures the stability and accuracy of the movement of the moving block 6. A motor 7 is fixed to the top front side of the moving block 6, and its output end is connected to a connecting sleeve 8. When the motor 7 starts to rotate, the connecting sleeve 8 rotates synchronously. A motor 9 is installed in front of the connecting sleeve 8, and its output end is connected to a bevel gear 10. As the motor 9 rotates, the bevel gear 10 rotates... When the motor starts rotating, it meshes with the bottom of the outer wall of the second bevel gear 11, and the second bevel gear 11 will also rotate. At the bottom of the second bevel gear 11, the rotating rod 12 is fixedly connected to it. The outer wall of the rotating rod 12 is also distributed with multiple stirring blades 13. The rotation of the second motor 9 can drive the stirring blades 13 to fully stir the cement in the cement bucket 14 placed on the front side of the top of the base plate 1.

When the connecting sleeve 8 rotates to a specific position, the fixed rod 15 and the extrusion plate 16 at the top will face downwards, the telescopic rod 4 will retract, and the extrusion plate 16 will extrude the cement inside the cement bucket 14, so that the strength of the cement can be detected.

[0042] Reference Figure 2 and Figure 6 The clamping mechanism 2 includes two fixed blocks 201. The bottoms of the two fixed blocks 201 are fixedly connected to the top left and right sides of the base plate 1. A round hole 202 is opened between adjacent fixed blocks 201. A pressing rod 203 is slidably connected inside the two round holes 202. A clamping ring 204 is fixedly connected between adjacent pressing rods 203. Two grooves 205 are opened on the top of the outer wall of the two pressing rods 203. A locking block 206 is slidably connected inside the multiple grooves 205. The pressing rod 203 is inserted into the round hole 202 in the fixed block 201, and then the two locking blocks 206 are inserted into the grooves 205. The clamping ring 204 can clamp the cement bucket 14 to prevent it from moving during mixing.

[0043] Specifically, two fixing blocks 201 are fixedly connected to the top left and right sides of the base plate 1, respectively. A round hole 202 is opened between the two adjacent fixing blocks 201. A pressing rod 203 is inserted into the round hole 202 and can slide flexibly. A clamping ring 204 is fixed at the opposite end of the two pressing rods 203. Two grooves 205 are also opened on the top of the outer wall of the pressing rod 203. A locking block 206 can slide into each groove 205. When it is necessary to fix the cement bucket 14, the pressing rod 203 is first inserted into the round hole 202, and then the locking block 206 is slid into the groove 205, so that the clamping ring 204 can clamp the cement bucket 14, effectively preventing the cement bucket 14 from shifting during mixing.

[0044] Reference Figure 1 and Figure 2 Support columns 17 are fixedly connected to the four corners of the bottom of the base plate 1. Anti-slip sleeves 18 are fixedly connected to the bottom of the multiple support columns 17 to prevent the device from moving when it is started. A cover plate 19 is provided in the middle of the outer wall of the rotating rod 12. The cover plate 19 is designed to prevent cement from splashing during mixing. Clip fasteners 20 are fixedly connected to the top of the left and right sides of the outer wall of the cement bucket 14. Pipe clamps 21 are fixedly connected to the left and right sides of the outer wall of the cover plate 19 to fix the cover plate 19 to the top of the cement bucket 14.

[0045] Specifically, support columns 17 are connected to the four corners at the bottom of the base plate 1. Anti-slip sleeves 18 are installed at the bottom of the support columns 17 to effectively increase friction and prevent the device from moving randomly due to vibration when it is started. A smooth cover plate 19 is designed in the middle of the outer wall of the rotating rod 12 to effectively block cement from splashing during mixing. On the top of the left and right sides of the outer wall of the cement bucket 14, there is a buckle 20 and pipe clamps 21 on both sides of the outer wall of the cover plate 19. The two work together to fix the cover plate 19 to the top of the cement bucket 14.

[0046] Reference Figure 3 and Figure 6 The bottom of the movable block 6 is fixedly connected to a connecting seat 22, and the bottom of the connecting seat 22 is fixedly connected to a camera 23 for recording the detection process. The tops of the multiple card blocks 206 are all fixedly connected to connecting blocks 24, and the tops of the multiple connecting blocks 24 are all fixedly connected to pull rings 25 for easy pulling of the card blocks 206. The diameters of the two extrusion rods 203 are smaller than the circular hole 202, and the multiple card blocks 206 are adapted to the groove 205.

[0047] Specifically, the bottom of the movable block 6 is connected to the connecting seat 22, and a camera 23 is installed under the connecting seat 22, which can record the entire process of cement testing and provide a basis for subsequent analysis. On the fixed structure of the device, the top of each locking block 206 is connected to the connecting block 24, and the connecting block 24 is provided with a pull ring 25, which makes it easy for the user to pull the locking block 206. The diameter of the extrusion rod 203 is smaller than that of the round hole 202, and the locking block 206 and the groove 205 are matched in size, which ensures that the device is stable and easy to operate.

[0048] Working principle: A fixed frame 3 is fixed to the top rear side of the base plate 1, which supports and positions other key components. When the telescopic rod 4 at the front end of the bottom inner side of the fixed frame 3 is activated, it will push the top moving block 6 upward or downward. The guide column 5 at the rear end of the bottom inner side of the fixed frame 3 provides a track for the movement of the moving block 6. The rear side of the moving block 6 moves smoothly up and down along the guide column 5, making the movement of the moving block 6 stable and accurate. The motor 7 installed on the front top of the moving block 6 is the key to controlling the rotation of the connecting sleeve 8. The output end of the motor 7 is connected to the connecting sleeve 8. When the motor 7 is powered on, the rotational power generated is directly transmitted to the connecting sleeve 8, causing the connecting sleeve 8 to rotate synchronously. On the front side of the connecting sleeve 8, the second motor 9 is installed. The output end of the second motor 9 is connected to the first bevel gear 10. When the second motor 9 starts working, the first bevel gear 10 rotates accordingly. Because the first bevel gear 10 and the second bevel gear 10 are connected to the first bevel gear 10, the motor 7 rotates smoothly up and down along the guide column 5, making the movement of the moving block 6 stable and accurate. The motor 7 installed on the front top of the moving block 6 is the key to controlling the rotation of the connecting sleeve 8. The output end of the first motor 7 is connected to the first bevel gear 10. When the second motor 9 starts working, the first bevel gear 10 rotates accordingly. The bottom of the outer walls mesh with each other, so that the rotation of the first bevel gear 10 can drive the second bevel gear 11 to rotate. At the bottom of the second bevel gear 11, the rotating rod 12 is fixed to it. The outer wall of the rotating rod 12 is also distributed with multiple stirring blades 13, which drive the stirring blades 13 to rotate and fully stir the cement in the cement bucket 14 placed on the top front side of the base plate 1, so that the cement is in a uniformly mixed state. The top of the connecting sleeve 8 is connected to the fixing rod 15, and the top of the pressing plate 16 is fixed to the pressing plate 16. When the connecting sleeve 8 rotates to a specific position, the fixing rod 15 and the pressing plate 16 will face downward with the rotation of the connecting sleeve 8, and the telescopic rod 4 will retract. The pressing plate 16 will then apply pressure to the cement inside the cement bucket 14 under the action of the telescopic rod 4. As the pressure gradually increases, the deformation and cracking of the cement under pressure can be observed to detect the strength of the cement and determine whether the cement meets the corresponding quality standards.

[0049] Furthermore, when it is necessary to fix the cement bucket 14, the two extrusion rods 203 are respectively inserted into the round holes 202 of the corresponding fixing blocks 201, and the extrusion rods 203 are pushed to slide in the round holes 202, so that the clamping ring 204 gradually approaches and wraps around the cement bucket 14. After the clamping ring 204 is adjusted to a suitable position, the locking block 206 is accurately slid into the groove 205 on the top of the outer wall of the extrusion rod 203. The locking block 206 plays a locking role, fixing the extrusion rod 203 in the current position, thereby allowing the clamping ring 204 to tightly clamp the cement bucket 14. During the subsequent cement mixing process, due to the stable clamping of the clamping ring 204, the cement bucket 14 is effectively prevented from shifting due to the vibration and force generated by mixing, ensuring the stable progress of cement mixing and testing.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
