[0024] Reference Figure 1-Figure 5The utility model provides a garbage collection device on the surface of a sedimentation tank, including a sedimentation tank body 4, a pushing assembly 3 is synchronously arranged on the silting mechanism of the sedimentation tank body 4, two guide rails 11 are fixed to the circumferential inner wall of the sedimentation tank body 4 by bolts, a slide 9 is slidably connected to one side of the two guide rails 11, an angle iron 13 is fixed between the two slides 9 by bolts, a connecting frame 7 is welded to one side of the angle iron 13, a collecting box 1 is fixed to one end of the connecting frame 7 by bolts, a driving component for moving the collecting box 1 up and down is arranged on the top of the sedimentation tank body 4, the driving component is a fixing frame 14, the fixing frame 14 is fixed to the top of the sedimentation tank body 4 by bolts, an oil cylinder 15 is fixed to the top outer wall of the fixing frame 14 by bolts, and the oil cylinder 1 One end of the piston rod passes through the fixing frame 14 and is fixed to the angle iron 13. By starting the oil cylinder 15, the oil cylinder 15 is extended and shortened, and the fixing frame 14 and the collecting box 1 are driven to move and adjust to a suitable position through the angle iron 13. A self-locking component is provided between the sedimentation tank body 4 and the angle iron 13. When the silting mechanism is started, the pushing component 3 is driven to rotate, so that the pushing component 3 pushes the garbage on the surface of the sewage in the sedimentation tank body 4 into the collecting box 1 and is collected. The silting mechanism is composed of a silting plate, a connecting shaft and a driving motor. The driving motor is fixedly installed on the frame at the top of the sedimentation tank. The silting plate is connected to the driving motor through the connecting shaft, and the silting plate contacts the inner wall of the bottom of the sedimentation tank and performs silt scraping operation. When the sewage in the sedimentation tank body 4 When the water level changes, the connecting frame 7 can be driven by the driving component to drive the collecting box 1 to move along the guide rail 11, so that the position height of the collecting box 1 can be adjusted, so that the top of the collecting box 1 is flush with the sewage level of the sedimentation tank body 4, thereby effectively avoiding the existing slag discharge port being fixed in position. When the water volume is large, a large amount of water enters the lifting pump room through the slag port, and repeated processing increases the power consumption. When the water volume is small, the slag port is higher than the liquid level, resulting in the slag cannot be discharged smoothly. A material guide inclined plate 8 is fixed to one side of the collecting box 1 by bolts, and the pushing assembly 3 includes a connecting square tube 5, one end of which is fixed to one side of the rotating main shaft on the dredging mechanism by bolts, and the bottom outer wall of the connecting square tube 5 is fixed with a soft scraper by bolts The soft scraper strip 6 is a rubber strip.
