[0025] like Figure 7-Figure 8As shown, the guide device 4 includes a fixed plate 41, which is fixedly connected to the inner wall of the fixed column 126, the third turntable 33 is arranged below the fixed plate 41, the top of the fixed plate 41 is fixedly connected to the second protruding column 412, the top of the fixed plate 41 is provided with a second arched hole 411, the top center position of the third turntable 33 is fixedly connected to a rotating rod 42, the rotating rod 42 passes through the fixed plate 41, the middle end outer wall of the rotating rod 42 is fixedly connected to a protruding piece 421, the rotating rod 42 is fixedly connected to a first rotating wheel 422 at one end away from the third turntable 33, one side of the first rotating wheel 422 is connected to a second rotating wheel 45 through a belt drive, the top of the second rotating wheel 45 is fixedly connected to a push rod 46 through a column, and the push rod 46 is fixedly connected to the top of the second rotating wheel 45. The rod 46 is located at the top of the platform 121, the push rod 46 is in a retractable state, and the bottom of the push rod 46 fits with the track. The middle end of the rotating rod 42 is slidably connected with the push plate 43, and the bottom of the push plate 43 is fixedly connected with a No. 3 raised column 431, and the diameter of the No. 3 raised column 431 matches the width of the No. 2 arch hole 411. A spring 44 is fixedly connected between the No. 3 raised column 431 and the No. 2 raised column 412, and the top of the push plate 43 is fixedly connected with a raised block 432, and the raised block 432 and the raised piece 421 are on the same horizontal plane. A No. 3 arch hole 433 is opened on the top of the push plate 43, and the width of the No. 3 arch hole 433 matches the diameter of the rotating rod 42, and the rotating rod 42 passes through the No. 3 arch hole 433.

[0026] It can be seen from this that when it is necessary to test permeable concrete, Figure 2-Figure 8As shown, the staff puts the measuring cup 5 full in the measuring cup entrance 14 in advance (here, the measuring cup 5 uses a cylindrical measuring cup 5 with the same diameter at the upper and lower ends. They will not be stacked on each other during the placement process, but will have a stacking effect), then opens the single-opening door 11 and places the cylindrical permeable concrete sample on the support ring 2, and against the position of the baffle 16, closes the single-opening door 11, and the measuring cup 5 falls into the arc groove 1211 through the measuring cup entrance 14. At this time, the No. 2 turntable 32 rotates together with the No. 1 raised column 322 under the drive of the motor 31. During the rotation of the No. 1 raised column 322, it will enter the No. 1 arch hole 331 and drive the No. 3 turntable 33 to rotate together. When the No. 1 raised column 322 rotates 90 degrees, it will break away from the No. 1 arch hole 331 and bring the No. 3 turntable 33 to rotate together. The third turntable 33 will rotate 90 degrees together. At this time, the third turntable 33 will drive the first turntable 422 to rotate through the rotating rod 42. The first turntable 422 will drive the second turntable 45 and the push rod 46 to rotate together. The push rod 46 will push the measuring cup 5 to the other end of the arc groove 1211 and fall into the regular column 1241. Then, during the rotation of the rotating rod 42, the first turntable 125 and the measuring cup 5 will be driven to rotate 90 degrees to the bottom of the first funnel 1213. At this time, the water inlet 15 starts to take in water to detect the water permeability of the permeable concrete. The water flowing down from the concrete will flow through the second funnel 21 to the first funnel 1213 and finally flow into the measuring cup. Under the rotation of the No. 1 turntable 125, the measuring cup is transported to the side of the weighing track 122.

[0027] It should be noted that the position of the push rod 46 is not the center of the platform 121. Under the limitation of the top track of the platform 121, the retractable push rod 46 will rotate and retract along the track, so that the end of the push rod 46 will always slide in the arc groove 1211 during the process of pushing the measuring cup 5, and no deviation will occur.

[0028] In addition, after the measuring cup 5 falls into the arc groove 1211, it is pushed by the push rod 46 to fall between the travel cover 124 and the No. 1 turntable 125, and until it is transported to the position of the weighing track 122, the push rod 46 is always in the same direction as the measuring cup 5, because when the rotating rod 42 drives the No. 1 turntable 125 to rotate 90 degrees, the push rod 46 also pushes the measuring cup 5 through the track until the measuring cup 5 is pushed again for the next detection.

[0029] When the measuring cup 5 is pushed to the position of the weighing track 122, the rotating rod 42 drives the protruding piece 421 to rotate together, and the protruding piece 421 is also in the same direction as the push rod 46 and staggered at a certain angle (the figure is a schematic diagram for the convenience of display), that is, the protruding piece 421 rotates to the direction of the weighing track 122 after the push rod 46 rotates 90 degrees for the next time. When the protruding piece 421 rotates to the position of the protruding block 432, the protruding block 432 and the push plate 43 will slide toward the direction of the weighing track 122 and push the measuring cup 5 onto the weighing pan 123, weigh the water in the measuring cup 5, calculate and detect, and finally obtain data, and the detection is completed.

[0030] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
