Once the garbage accumulates to a certain level, it will issue a timely reminder to prevent garbage from overflowing or clogging the equipment. Optionally, the pressure sensor 13 is located below the garbage collection box 12.

[0040] In summary, the utility model has a screen machine with adjustable rake teeth length. After starting the equipment, the first driving member 4 drives the active sprocket 1 to rotate, which is connected to the driven sprocket 2 through the bar transmission chain 3, so that the bar system tilts to intercept solid waste in the fluid; at the same time, the adjustment gear 8 engages with the adjustment serrations 9 on the rake teeth, and the second driving member drives the adjustment gear 8 to rotate to change the extension or retraction of the rake teeth, so that the screen machine can flexibly adjust the length of the rake teeth according to different types of waste, optimize the sewage interception effect, and improve the overall treatment efficiency; in addition, the screen machine is easy to operate and has strong adaptability, and is suitable for various environmental requirements in sewage treatment plants, drinking water purification plants, power plant water diversion systems, and other industrial wastewater treatment facilities.
