[0024] like Figure 1 - Figure 4As shown in the figure, the steel bar spacing detection device provided in this embodiment includes two fixed rails 1. A moving trolley 2 is movably installed at the lower ends of the two fixed rails 1. An installation rod 9 is installed at the lower end of the moving trolley 2. An installation plate 8 is fixedly installed at the upper end of the installation rod 9. A screen 6 is installed at the lower end of the installation rod 9. A material cylinder 3 is arranged outside the screen 6. A rotating seat 11 is movably sleeved outside the installation plate 8. A rotating sleeve 10 is fixedly installed at the lower end of the rotating seat 11. The rotating sleeve 10 is movably sleeved outside the installation rod 9. Scraping bars 5 are arranged on both sides of the lower end of the rotating sleeve 10. The lower ends of the scraping bars 5 are in contact with the surface of the screen 6. The fixed rail 1 is in a "U" shape. Installation blocks are fixedly installed on both sides of the upper end of the moving trolley 2. A pulley 4 is movably installed on one side of the installation block. The pulley 4 is movably inserted into the interior of the fixed rail 1. A transmission gear ring 12 is arranged outside the rotating seat 11. A motor 7 is installed at the upper end of the moving trolley 2. A transmission gear 13 is fixedly installed at the transmission end of the motor 7. The transmission gear 13 meshes with the transmission gear ring 12;

[0025] In this embodiment, the moving trolley 2 moves along the fixed rail 1 through the pulley 4 (a driving device for helping the moving trolley 2 move can be set). The material pipes can be arranged on both sides of the upper end of the material cylinder 3. Materials are put into the interior of the material cylinder 3 through the material pipes and fall on the surface of the screen 6. The motor 7 operates. The motor 7 drives the rotating seat 11 to rotate through the transmission gear 13 and the transmission gear ring 12. The rotating seat 11 drives the scraping bars 5 to rotate through the rotating sleeve 10. The rotation of the scraping bars 5 on the surface of the screen 6 can stir the materials inside the material cylinder 3, can stir the materials, can also accelerate the feeding speed, and can also filter out impurities in the materials. The falling materials move along with the moving trolley 2 and can be evenly spread on the filter cloth, and can evenly measure the water content at different positions of the sludge on the filter cloth.

[0026] As Figures 2 to 4 shown in the figure, a connection structure is arranged between the installation plate 8 and the moving trolley 2. The connection structure includes installation holes. Multiple installation holes are formed on the surface of the moving trolley 2. The installation holes are located above the installation plate 8. Multiple installation screw sleeves 15 are rotatably installed at the upper end of the moving trolley 2. The installation screw sleeves 15 are connected to the installation holes. An installation bolt 14 connected to the installation plate 8 is movably inserted into the interior of the installation screw sleeve 15. The installation bolt 14 is threadedly connected to the installation screw sleeve 15. An installation gear 16 is arranged outside the installation screw sleeve 15. An adjustment ring seat 22 is arranged at the upper end of the moving trolley 2. An installation gear ring 23 that cooperates with the installation gear 16 is arranged at the lower end of the adjustment ring seat 22;

[0027] In this embodiment, when maintenance of the screen 6 is required, the user rotates the adjusting ring seat 22. The adjusting ring seat 22 drives multiple mounting gears 16 to rotate through the mounting toothed ring 23. The mounting gears 16 drive the mounting screw sleeve 15 to rotate, so that the mounting bolt 14 can be pulled out from the inside of the mounting bolt 15, so that the mounting plate 8 and the rotating seat 11 are separated from the moving trolley, and the screen 6 and the material cylinder 3 are separated from the moving trolley 2, which facilitates the maintenance of the screen 6.

The installation ring 21 is movably connected to the adjusting ring seat 22. A support spring 19 connected to the movable ring 18 is sleeved on the surface of the support rod 20. An annular groove is opened on the surface of the installation ring 21. An annular rail that matches the annular groove is fixedly installed on the lower end of the adjusting ring seat 22.

[0029] In this embodiment, after the mounting plate 8 is connected to the moving trolley 2 and the screen 6 is installed, the moving ring 18 is supported by the support spring 19. The moving ring 18 can be supported by the support rod 20 to support the mounting ring 21. The mounting ring 21 supports the adjusting ring seat 22, so that the mounting toothed ring 23 is disengaged from the mounting gear 16. This prevents the adjusting ring seat 22 from rotating when the moving trolley 2 moves, thus avoiding any impact on the connection between the mounting sleeve 15 and the mounting bolt 14.
