[0025] The cleaning mechanism 3 includes a support frame 301 located below two conical barrels 2. A sliding frame 302 is fixedly connected to the outer surface of each conical barrel 2. Each sliding frame 302 is slidably connected inside the support frame 301. Two support seats 6 are fixedly connected to the upper surface of the water storage tank 1. The upper surface of each support seat 6 is fixedly connected to the bottom surface of the support frame 301. The support seats 6 can fix the position of the support frame 301 on the water storage tank 1, increasing the stability and reliability of the support frame 301 during use.

[0026] A dual-axis motor 303 is installed below the conical barrel 2. The upper surface of the dual-axis motor 303 is fixedly connected to the bottom surface of the support frame 301. Both output ends of the dual-axis motor 303 are fixedly connected to screws 304. The outer surface of each screw 304 is threadedly connected to the inner wall of the sliding frame 302. The outer surface of each screw 304 is rotatably connected to a positioning frame 7. The upper surface of each positioning frame 7 is fixedly connected to the bottom surface of the support frame 301. The threads of the two screws 304 are opposite in direction. The positioning frame 7 can further position the screws 304 and increase the stability of the screws 304 when rotating.

[0027] Two fixed brackets 305 are fixedly connected to the upper surface of the support frame 301. A pressure bracket 306 is provided above the conical barrel 2. A water pump 307 is fixedly connected to the upper surface of the pressure bracket 306. A connecting hose 308 is fixedly connected to the water inlet end of the water pump 307. The end of the connecting hose 308 away from the water pump 307 passes through the support frame 301 and the water storage tank 1 and extends into the interior of the water storage tank 1. Reinforcing ribs 8 are fixedly connected to the opposite sides of the two fixed brackets 305. The bottom surfaces of the two reinforcing ribs 8 are fixedly connected to the upper surface of the support frame 301. The reinforcing ribs 8 can increase the tightness of the connection between the fixed bracket 305 and the support frame 301, making the fixed bracket 305 less prone to loosening and shaking, and improving the pressure resistance of the fixed bracket 305.

[0028] Sliding blocks 309 are fixedly connected to both the front and back of the lower pressure frame 306. Both sliding blocks 309 are slidably connected to the interior of the fixed frame 305.

A sliding rod 9 is provided inside each compression spring 310. The bottom end of each sliding rod 9 is fixedly connected to the inner bottom wall of the fixed frame 305, and the top end of each sliding rod 9 is fixedly connected to the inner top wall of the fixed frame 305. The inner wall of each sliding block 309 is slidably connected to the outer surface of the sliding rod 9. The sliding rod 9 can increase the sliding stability of the sliding block 309 inside the fixed frame 305, making the sliding block 309 less prone to displacement and improving the reliability of the sliding block 309.

[0029] A hollow tube 313 is fixedly connected to the inner wall of the inner ring of the sealed bearing 312. Several nozzles 314 are fixedly connected to the outer surface of the hollow tube 313. Each nozzle 314 is at a certain angle to the hollow tube 313. The water outlet of the water pump 307 passes through the sealing cover 311 and extends into the interior of the sealing cover 311. A movable plate 315 is slidably connected inside the support frame 301. The bottom surface of each conical barrel 2 is in contact with the upper surface of the movable plate 315. A drainage groove 316 is provided on the upper surface of the movable plate 315. A guide groove 317 is provided on the upper surface of the support frame 301. Limiting frames 10 are fixedly connected to both sides of the movable plate 315. The right side of one of the limiting frames 10 is in contact with the left side of the support frame 301. The limiting frame 10 can limit the sliding position of the movable plate 315 inside the support frame 301, prevent the movable plate 315 from becoming loose from the support frame 301, and increase the accuracy of the movable plate 315.

[0030] The working principle of this utility model is as follows: In use, the dual-shaft motor 303 and the water pump 307 are first connected to an external power source and controller. When it is necessary to test the slump of the concrete, the power provided by the dual-shaft motor 303 drives the screw 304 to rotate. This, combined with the opposing threads on the two screws 304, allows the two sliding frames 302 to bring the two conical barrels 2 closer together until they are in complete contact. At this point, concrete can be poured into the space formed by the two conical barrels 2. Then, the dual-shaft motor 303 reverses direction, driving the two conical barrels 2... Quick separation allows observation of the concrete slump, enabling slump testing. When cleaning the inner wall of the conical barrel 2 is required, first manually pull the moving plate 315 to the left using the limit frame 10, positioning the drainage trough 316 above the guide trough 317. At this point, the tested concrete on the moving plate 315 can be cleaned. Then, the dual-axis motor 303 rotates again, causing the conical barrel 2 to merge, with the conical barrel 2 positioned above the drainage trough 316. By manually pressing down the lowering frame 306, the sliding block 309 can slide inside the fixed frame 305. This forces the compression spring 310 to contract, simultaneously causing the hollow tube 313 to move downwards and insert between the two conical barrels 2 until the bottom surface of the lower pressure frame 306 contacts the upper surface of the conical barrel 2. At this point, using the suction force provided by the water pump 307 in conjunction with the connecting hose 308, the clean water inside the water storage tank 1 can be drawn out and sprayed into the conical barrel 2 through the sealing cover 311, the hollow tube 313, and the nozzle 314. Utilizing the angle between the nozzle 314 and the hollow tube 313, as well as the auxiliary rotation of the sealed bearing 312, the nozzle 314 can spray water while simultaneously... The hollow tube 313 is rotated inside the conical barrel 2 by the impact force of the water flow, which increases the rinsing effect on the conical barrel 2. Finally, the wastewater can be discharged outward through the drainage channel 316 and the guide channel 317, allowing the concrete slump testing device to quickly clean the conical barrel 2 after concrete slump testing without the need for manual cleaning by staff. This reduces the amount of residual concrete on the inner wall of the conical barrel 2, improves the ease of cleaning the conical barrel 2, and enables the concrete slump testing device to quickly carry out the next concrete slump test, ensuring the efficiency of concrete slump testing.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
