The input end of the water pump 11 is connected to an external pipeline 12, and the output end of the water pump 11 is connected to a connecting pipe 13. One end of the connecting pipe 13 is connected to a shunt pipe 14. A plurality of nozzles 15 are evenly distributed on the outer side of the shunt pipe 14. A cylinder 16 is provided at one end of the test bench 2. The output end of the cylinder 16 movably penetrates through the test bench 2 and is connected to a scraper 17.

[0023] In this embodiment, an external water source can be connected through the external pipeline 12. The water pump 11 is used to pump water in, and the water is conveyed to the shunt pipe 14 through the connecting pipe 13, and then the water is sprayed out by the nozzle 15 to wash the polyurethane mortar on the test bench 2. At the same time, after the washing is completed, the cylinder 16 is used to push the scraper 17, so that the residual mortar and water on the test bench 2 can be completely scraped off, thereby preventing mortar residue, ensuring the subsequent use of the device, and at the same time, there is no need for manual cleaning, effectively reducing the cleaning difficulty, saving labor costs, and improving the overall work efficiency.

[0024] Embodiment 2

[0025] As Figures 1 - 4 shown, mounting brackets 3 are symmetrically arranged at the bottom on both sides of the test bench 2. A fixing bracket 4 is arranged at the top of the mounting bracket 3. A guide rod 5 is arranged inside the fixing bracket 4. A motor 6 is arranged at the top of the fixing bracket 4. The output end of the motor 6 movably penetrates through the fixing bracket 4 and is connected with a lead screw 7. A first slider 8 is arranged on the outer sides of the guide rod 5 and the lead screw 7. One end of the first slider 8 is connected with a hydraulic telescopic rod 9. One end of the hydraulic telescopic rod 9 is connected with a thumb gripper 10. A second slider 18 is arranged on the outer sides of the guide rod 5 and the lead screw 7. The adjacent ends of the two second sliders 18 are fixedly connected with a connecting frame 19. A docking pipe 20 is arranged at the bottom of the connecting frame 19. One end of the docking pipe 20 penetrates through the connecting frame 19 and is connected with a filling port 21. A test mold 22 is arranged on the top of the test bench 2. Two handles 24 are symmetrically arranged on the outer side of the test mold 22. A docking port 23 is arranged on the top of the test mold 22. The docking port 23 is arranged directly below the docking pipe 20. Anti-slip foot pads 26 are arranged at the four corners of the bottom of the test device body 1.

[0026] In this embodiment, the thumb gripper 10 is pushed by the hydraulic telescopic rod 9 to clamp and fix the test mold 22, preventing the mortar from flowing out from the bottom of the test mold 22. And after the grouting work is completed, the motor 6 is used to drive the lead screw 7 to rotate, so that the first slider 8 drives the thumb gripper 10 and the test mold 22 clamped by the thumb gripper 10 to slide on the guide rod 5 and the lead screw 7, and then the test mold 22 is pulled out, so that the polyurethane mortar flows on the test bench 2, thereby reducing the influence of manual operation on the test work, effectively improving the test efficiency, and improving the test accuracy.

[0027] Working principle of this embodiment: During use, first start the motor 6 to drive the screw rod 7 to rotate, prompting the first slider 8 and the second slider 18 to slide downward on the guide rod 5 and the screw rod 7. Then, insert the docking pipe 20 into the docking port 23 to complete the docking. At the same time, the hydraulic telescopic rod 9 pushes the thumb gripper 10 to clamp the handle 24, fixing the test mold 22 on the test bench 2. Then, inject the polyurethane mortar to be tested from the material injection port 21. After the injection is completed, start the motor 6 again, so that the first slider 8 drives the test mold 22 to slowly rise, thereby causing the polyurethane mortar to flow out from the bottom of the test mold 22 and slowly flow on the test bench 2. Let it stand for a period of time and wait for the polyurethane mortar to stop flowing. At this time, observe the scale line 25, record the flow diameter of the polyurethane mortar, and measure its fluidity. Finally, connect the external pipe 12 to an external water source, start the water pump 11 to pump water in, and transport it to the shunt pipe 14 through the connecting pipe 13. The water is sprayed out by the nozzle 15 to wash the polyurethane mortar on the test bench 2. After the washing is completed, start the cylinder 16 to push the scraper 17 to scrape off the residual polyurethane mortar and water on the test bench 2, thus completing the use of the polyurethane mortar floor material fluidity testing device.
