Description

Technical Field

[0001] This utility model relates to the field of concrete testing technology, specifically a concrete slump and air content testing device. Background Technology

[0002] A concrete slump and air content testing device is commonly used to determine the slump (flowability) and air content of concrete. These parameters are crucial for the workability and quality control of concrete. However, an existing concrete slump testing device (publication number: CN216285291U) has the following drawbacks in use:

[0003] In its use, the slump test tube is placed in the middle, and the fixed plate at the bottom of the slump test tube is fixed by a rotatable limiting rod. After fixing, concrete can be filled into the slump test tube. When the pin is pulled out and the limiting rod releases the limiting of the fixed plate, the slump test tube can be lifted to measure the slump and spread of the concrete. However, after the measurement, the concrete falls onto the test table and needs to be cleaned by the staff with tools, otherwise it will affect the subsequent experiments. Therefore, this patent proposes a concrete slump air content test device to solve the above problems. Utility Model Content

A second rotating wheel is slidably connected to the outer walls of the second rotating rod and the limit strip. A connecting frame is fixed to one side of the bottom plate. The second rotating wheel is fixed to the connecting frame. A belt is provided between the first rotating wheel and the second rotating wheel. A second motor is fixed to the other side of the collection box. The output end of the second motor passes through the collection box and is fixed to the first rotating rod.

This way, the workers do not need to clean the concrete on the base plate afterward, saving a lot of labor.

[0013] In addition, the second motor drives the first rotating rod to rotate, which in turn drives the first rotating wheel to rotate. The first rotating wheel then drives the belt to move, which in turn drives the second rotating wheel to rotate. The second rotating wheel then drives the second rotating rod to rotate, which in turn drives the first auger to rotate and transport the concrete. The concrete is then pumped into the storage bin by the delivery pump. The second rotating rod drives the second auger to rotate, causing the concrete to be discharged from the discharge pipe. In this way, the concrete after the slump test is collected and can be used for subsequent concrete air content tests. This eliminates the need for manual collection of concrete and feeding it into the concrete air content meter for testing, saving a lot of labor. Attached Figure Description

The concrete slump air content test device provided by this utility model can clean the surface of the base plate 1 after the experiment, thus eliminating the need for manual cleaning of the surface of the base plate 1.

[0021] like Figures 1-4As shown, this utility model provides a technical solution: a concrete slump air content testing device, including a base plate 1, a slump bucket 2 and a concrete air content measuring instrument 3 placed on the top of the base plate 1, a cleaning mechanism 4 provided on one side of the top of the base plate 1, the cleaning mechanism 4 including a fixing member 401 fixed to the top of the base plate 1, a screw rod 402 rotatably connected between the inner walls of the two ends of the fixing member 401, a slider 403 screwed to the outer wall of the screw rod 402, a connecting rod fixed between the inner walls of the two ends of the fixing member 401, the connecting rod passing through the slider 403, a fixing rod 404 fixed on one side of the slider 403, a cleaning plate 405 installed at the bottom of the fixing rod 404, the cleaning plate 405 being fixed to the fixing rod 404 by bolts, a first motor fixed to one end of the fixing member 401, the output end of the first motor passing through the fixing member 401 and fixed to the screw rod 402.

[0022] It should be noted that by starting the first motor, the first motor drives the lead screw 402 to rotate, the rotation of the lead screw 402 drives the slider 403 to move, the movement of the slider 403 drives the fixed rod 404 to move, and the movement of the fixed rod 404 drives the cleaning plate 405 to clean the surface of the base plate 1.

[0023] like Figure 1 and Figure 2 As shown, a connection port 6 is provided at the top of the base plate 1, and a collection box 5 is fixed at the bottom of the base plate 1. The collection box 5 is located directly below the connection port 6. A first rotating rod 7 is rotatably connected between the inner walls of both sides of the collection box 5. A first auger 8 is fixed to the outer wall of the first rotating rod 7. A mounting frame 11 is slidably connected to the top of the base plate 1.

An inlet pipe 15 is fixedly connected to one side of the top of the storage box 14, and an outlet pipe 16 is fixedly connected to the other side of the bottom of the storage box 14.

[0024] It should be noted that the cleaning plate 405 cleans the concrete on the surface of the base plate 1, and the concrete falls from the connection port 6 into the collection box 5. The first rotating rod 7 drives the first auger 8 to rotate, so that the concrete is transported to the storage box 14 by the delivery pump 12.

[0025] like Figure 1 and Figure 3As shown, the first rotating rod 7 passes through one side of the collection box 5 and its outer wall is fixed with a first rotating wheel 17. The inner walls of the two sides of the storage box 14 are rotatably connected to a second rotating rod 19. The outer wall of the second rotating rod 19 is fixed with a second auger. The outer wall of the second rotating rod 19 passes through one side of the storage box 14 and its outer wall is fixed with a limit strip 21.

In this way, the concrete after the slump test is collected and can be used for subsequent concrete air content tests. This eliminates the need for manual collection of concrete and feeding it into the concrete air content measuring instrument 3 for testing, saving a lot of labor. In addition, the second motor drives the first rotating rod 7 to rotate, the first rotating rod 7 drives the first rotating wheel 17 to rotate, the first rotating wheel 17 drives the belt to move, the belt drives the second rotating wheel 20 to rotate, and the second rotating wheel 20 drives the second rotating rod 19 to rotate.

[0027] like Figure 4 As shown, both the slump bucket 2 and the concrete air content meter 3 have bases 22 fixed to their bottom outer walls. Slots 23 are provided at both ends of the top of the base 22. Fixing blocks 24 are fixed at both ends of the base plate 1. A rotating rod 25 is rotatably connected to the top of the fixing blocks 24. An installation rod 26 is fixed to the top of the rotating rod 25.
