[0021] See also Figures 1 to 4The utility model provides a technical solution: a portable concrete detection device, including a base 1, a convex limiting groove 14 is provided inside the base 1, a convex limiting block 15 is slidably connected to the inside of the convex limiting groove 14, and the top of the convex limiting block 15 is threadedly connected to the collecting pan 2, and the collecting pan 2 is provided with a collecting cavity 3, and a slump cylinder 4 is placed inside the collecting cavity 3.

The threaded connection structure facilitates the installation and disassembly of the collecting pan 2 and the cleaning of the concrete mixture. Limiting plates 32 are installed on both sides corresponding to the cylinder 4. One end of the limiting plate 32 is in contact with the aggregate cavity 3 and presses against the aggregate cavity 3 to limit the slump cylinder 4, which is convenient for standardizing the position of the slump cylinder 4. A mounting frame 31 is installed on the top of the base 1 and on one side of the aggregate tray 2. The interior of the mounting frame 31 is rotatably connected to the support cylinder 5, and the interior of the support cylinder 5 is slidably connected to the adjusting frame 6. A convex chute 7 is provided inside the adjusting frame 6, and the interior of the convex chute 7 is slidably connected to the convex slider 8. One side of the convex slider 8 is connected to a bracket 9. The bottom of the bracket 9 is rotatably connected to a support plate 10. A plurality of tamping rods 11 are connected to the bottom of the support plate 10. The interior of the convex chute 7 is rotatably connected to a reciprocating screw rod 12. The reciprocating screw rod 12 passes through the convex slider 8 and is in contact with the convex The slider 8 is threadedly connected, so that the convex slider 8 drives the bracket 9 and the support plate 10 to rise and fall as the reciprocating screw 12 rotates. The multiple tamping rods 11 at the bottom of the support plate 10 are then inserted into the slump cylinder 4 to facilitate tamping the mixture. A second motor 13 is installed on the top of the adjusting frame 6. The output end of the second motor 13 is connected to the reciprocating screw 12 to provide power for the rotation of the reciprocating screw 12. A third motor 22 is installed on the top of the bracket 9. The output end of the third motor 22 is connected to the support plate 10 to provide power for the rotation of the support plate 10 and the multiple tamping rods 11. A telescopic spring 16 is installed inside the convex limiting groove 14, and one end of the telescopic spring 16 is connected to the convex limiting block 15. One side of the convex limiting block 15 is rotatably connected to a pulley 17. The convex limiting groove 1 4 and is located on one side of the pulley 17 and is rotatably connected with an eccentric cam 18. A first motor 19 is fixedly installed inside the base 1. The output end of the first motor 19 is connected to the eccentric cam 18, driving the eccentric cam 18 to rotate. Cooperating with the deformation of the telescopic spring 16, the eccentric cam 18 pushes the pulley 17 and the convex limit block 15 to repeatedly move. The aggregate tray 2 and the slump cylinder 4 then shake slightly, so that the concrete in the slump cylinder 4 is more evenly distributed. One side of the support cylinder 5 is threadedly connected with a first locking bolt 23. One end of the first locking bolt 23 extends into the support cylinder 5, so that the adjusting frame 6 can slide in the support cylinder 5 and be lifted and lowered. By rotating the first locking bolt 23, one end of the adjusting frame 6 is displaced and pressed against the adjusting frame 6, thereby fixing the adjusting frame 6.In order to adjust the overall length of the support tube 5 and the adjustment frame 6, an adjuster 24 is installed on one side of the mounting frame 31. The internal rotation of the adjuster 24 is connected to the worm gear 25 and the worm 26. The worm gear 25 and the worm 26 are engaged with each other. The top of the adjuster 24 is rotatably connected to the handle 27. The worm gear 25 and the worm 26 are connected to the support tube 5 and the handle 27 respectively. Under the action of the worm gear 25 and the worm 26, the handle 27 and the support tube 5 are driven to push the support tube 5 to rotate and fold it, so as to shorten the length of the support tube 5 and the adjustment frame 6, so as to reduce the space occupied when not in use. A measuring rod 28 is rotatably connected to the top of the base 1, located on the side of the collecting pan 2 away from the support tube 5.

One end of the second locking bolt 30 extends into the through-hole, allowing the measuring plate 29 to adjust its position as the measuring rod 28 rotates, and to rise and fall in conjunction with the sliding of the measuring plate 29. The second locking bolt 30 is then rotated to fix the measuring plate 29, making it easier for the measuring plate 29 to measure the height of the concrete mixture.

[0022] In summary, when the portable concrete detection device is used, the slump cylinder 4 is placed in the aggregate cavity 3 in the aggregate tray 2 on the base 1, and one end of the limit plates 32 on both sides of the slump cylinder 4 is against the aggregate cavity 3. After the concrete mixture is filled into the slump cylinder 4 to a certain amount, the first motor 19 drives the eccentric cam 18 to rotate. Since the convex limit groove 14 in the base 1 is slidably connected with the convex limit block 15, the convex limit block 15 is threadedly connected to the aggregate tray 2, and the convex limit The block 15 is provided with a telescopic spring 16 and a pulley 17 on both sides. Therefore, the eccentric cam 18 pushes the pulley 17 and the convex limit block 15 to repeatedly move, and the aggregate plate 2 and the slump cylinder 4 shake slightly, and the concrete mixture in the slump cylinder 4 is evenly distributed. At this time, the second motor 13 drives the reciprocating screw 12 in the adjusting frame 6 to rotate, and the reciprocating screw 12 is connected to the convex slider 8 through a threaded connection, so that the convex slider 8 drives the bracket 9 and the multiple tamping rods 11 below it to move downward. The tamping rods 11 are moved so that the tamping rods 11 are inserted into the slump cylinder 4. After the third motor 22 drives the support plate 10 and the multiple tamping rods 11 to rotate a certain number of circles, the multiple tamping rods 11 are pulled out from the slump cylinder 4 and the concrete mixture is filled into the slump cylinder 4 again. The operation is repeated. After the end, the slump cylinder 4 is lifted up and separated from the mixture. The height of the soil mixture is measured by the measuring plate 29, and the aggregate tray 2 collects the mixture. When the mixture needs to be cleaned, the aggregate tray 2 is rotated to separate it from the convex limit block 15. At the same time, since the support cylinder 5 is slidably connected to the adjusting frame 6 and is fixed under the action of the first locking bolt 23, the worm gear 25 and the worm 26 engaged in the adjuster 24 are respectively connected to the support cylinder 5 and the handle 27. Therefore, rotating the handle 27 can drive the support cylinder 5 and the adjusting frame 6 to rotate, fold, and slide the adjusting frame 6, shortening the overall length of the support cylinder 5 and the adjusting frame 6, and reducing the volume of the device.

[0023] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
