[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the specification of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0032] Refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 5, An embodiment provided by the present utility model: a concrete rheology regulation test device, including a bottom plate 1. Above the middle of the top surface of the bottom plate 1, there is a barrel 13. An ultrasonic vibrator 14 is fixedly connected to the outer wall of the barrel 13. A rheology detector 15 is installed inside the barrel 13. On both sides of the top surface of the bottom plate 1, there are lifting components for lifting the support plate 3. The support plate 3 is at the top of the lifting components. In the middle of the top surface of the support plate 3, there is a motor 4 fixedly connected. The output end of the motor 4 is fixedly connected to a rotating shaft 5. At the bottom of the rotating shaft 5, there is a scraping plate 6 fixedly connected. The outer wall of the scraping plate 6 is in contact with the inner wall of the barrel 13. In the middle of the bottom surface of the support plate 3, there is a support column 7 fixedly connected. The rotating shaft 5 is rotatably connected to the middle of the support column 7. Through holes 8 are opened on the outside of the support column 7. On one side of the top surface of the support plate 3, there is a water pump 9 fixedly connected. The output end of the water pump 9 is fixedly connected to a water pipe 10. The water pipe 10 is fixedly connected to the through hole 8 at the top of one side of the support column 7.
[0033] During use, first use the sleeved lifting component to move the scraping plate 6 out of the barrel 13, and then pour the concrete into the barrel 13. At this time, the ultrasonic vibrator 14 can vibrate the concrete, and the rheology detector 15 can be used to test the rheology of the concrete. When the test is over, the concrete is discharged. Then use the lifting component to make the scraping plate 6 enter the inner wall of the barrel 13 and make its outer wall contact with the inner wall of the barrel 13. Then connect the water pump 9 to the water source and drive the water pump 9. At this time, water can enter the support column 7 along the water pipe 10 and spray out from the through hole 8. At this time, drive the motor 4 to drive the rotating shaft 5 and the scraping plate 6 to rotate. Therefore, the inside of the barrel 13 can be scrubbed, and the bottom of the barrel 13 can be cleaned by the bottom of the scraping plate 6, and the side wall of the barrel 13 can be cleaned by the side wall of the scraping plate 6. Therefore, the residue of the concrete can be avoided from affecting the accuracy of the next concrete test.
[0034] Referring to Figure 1 , Figure 3 and Figure 4 , the lifting component includes a bracket 2 and an electric push rod 11. The bracket 2 is fixedly connected to the outside of the middle of the top surface of the bottom plate 1. The electric push rod 11 is fixedly connected to the middle of the top inner wall of the bracket 2. The bottom of the electric push rod 11 is fixedly connected to the bottom plate 1. The output end of the electric push rod 11 is fixedly connected to the bottom surface of the support plate 3. On the front and back sides of the middle of one side of the bottom surface of the support plate 3, there are guide rods 12 fixedly connected. The two guide rods 12 are respectively slidably connected to both sides of the top of the bracket 2.
[0035] Driving the electric push rod 11 can push the support plate 3 out or retract it. Therefore, the support plate 3 can be lifted or lowered, and the movement direction of the support plate 3 can be guided by the guide rods 12, thereby improving the overall operation stability of the device.
[0036] Referring to Figure 1, a discharge pipe 16 is fixedly connected to the middle of the bottom surface of the barrel body 13, and a sealing cover 17 is threadedly connected to the bottom of the discharge pipe 16. Legs 18 are fixedly connected to the bottom of the barrel body 13, and the bottoms of the legs 18 are fixedly connected to the bottom plate 1.
[0037] After the test is over, the concrete can be discharged from the discharge pipe 16 through the sealing cover 17.
[0038] Refer to Figure 1 , Figure 4 and Figure 5 , a cavity is provided inside the support column 7, and the through hole 8 communicates with the cavity. A sliding hole is provided in the middle of the support column 7, and the rotating shaft 5 is rotatably connected inside the sliding hole.
[0039] By providing a cavity inside the support column 7, when water enters the support column 7, it will first enter the inside of the cavity, and finally the water will enter the through hole 8 from the cavity. And through the sliding hole in the middle of the support column 7, a space for installing the rotating shaft 5 can be provided, and at this time the support column 7 can also limit the rotating shaft 5, thereby improving the smoothness of the rotation of the rotating shaft 5.
[0040] Refer to Figure 1 , Figure 4 and Figure 5 , an air pump 19 is fixedly connected to the other side of the top surface of the support plate 3, the output end of the air pump 19 is fixedly connected to an air pipe 20, and the air pipe 20 is fixedly connected to the through hole 8 at the top of the other side of the support column 7.
[0041] After the cleaning is over, the air pump 19 is driven to send gas along the air pipe 20 into the cavity inside the support column 7, and finally the gas is ejected from the through hole 8. At this time, the water remaining on the side wall of the barrel body 13 can be air-dried, and under the action of the air flow, the water can be forced to flow along the side wall of the barrel body 13 to the bottom of the barrel body 13. Therefore, the discharge of water can be promoted, and thus it can be avoided that in the next test, the remaining water is mixed with the concrete, resulting in a change in the composition ratio of the concrete, thereby affecting the accuracy of the test results.
[0042] Working principle: When in use, first drive the electric push rod 11 to extend its output end to push out the support plate 3, so that the scraping plate 6 is moved out of the interior of the barrel body 13 and is positioned above the barrel body 13. Subsequently, pour the concrete to be tested into the interior of the barrel body 13. The concrete inside the barrel body 13 can be vibrated by driving the ultrasonic vibrator 14, and the rheological properties of the concrete can be detected by using the rheological detector 15. Moreover, by changing the frequency of the ultrasonic vibrator 14, the rheological properties of the concrete under different vibration frequencies can be detected. When the test is completed, open the sealing cover 17 to discharge the concrete inside the barrel body 13 from the discharge pipe 16. Then tighten the sealing cover 17 and drive the electric push rod 11 to retract its output end, so that the scraping plate 6 enters the barrel body 13. Subsequently, connect the input end of the water pump 9 to a water source, and drive the water pump 9 to convey water into the water pipe 10. At this time, the water can enter the cavity of the support column 7 along the water pipe 10 and finally spray out from the through hole 8. At this time, the interior of the barrel body 13 can be rinsed, and drive the motor 4 to drive the rotating shaft 5 and the scraping plate 6 to rotate. At this time, the inner wall of the barrel body 13 can be scrubbed. Moreover, the side wall of the scraping plate 6 is in contact with the inner wall of the barrel body 13. Therefore, the bottom of the scraping plate 6 can scrub the bottom of the barrel body 13, and the side wall of the scraping plate 6 can clean the side wall of the barrel body 13, thereby improving the quality of cleaning and avoiding the residue of concrete. When the cleaning is completed, open the sealing cover 17 to discharge the water and the residual concrete from the discharge pipe 16. Then drive the air pump 19 to convey gas into the air pipe 20 and the cavity of the support column 7. At this time, the gas can spray out from the through hole 8, and thus the water remaining on the inner wall of the barrel body 13 can be air-dried. When the water inside the barrel body 13 is air-dried, stop the air pump 19 and drive the electric push rod 11 to lift the support plate 3. At this time, the next concrete test can be realized.
