[0002] The reverse scoop screen cleaning machine is widely used in the water intakes of sewage treatment plants, drinking water intakes, large hydropower stations, river and lake comprehensive management projects, rainwater drainage and sewage lifting pump stations. The equipment uses rake teeth to salvage floating objects and sediments at the water source intake and lift them out of the water surface. When the rake teeth rotate to the top and reverse, the dirt is dumped into the dirt hopper, and the water flows through the screen to the rear water purification area.

[0003] The main structure of the existing reverse scoop type screen cleaning machine includes a frame, a traction chain, a transmission system, a tooth rake assembly, an underwater guide wheel, a screen frame and a pressure plate. The screen frame is fixed in the screen channel through a guide rail;

[0004] The bottom of the garbage cleaning machine is submerged in water. When the tooth rake assembly is used to salvage branches and animal carcasses on the water surface, the tooth rake assembly is not convenient for applying force to the branches and animal carcasses, which easily leads to failure in salvaging large-sized garbage in the river.

Multiple groups of salvage rings 56 are evenly installed on the fixed shaft 55.

[0022] Working principle: The submerged part 2 at the bottom of the garbage cleaning machine body 1 is tilted and set in the water. At this time, under the operation of the chain drive component 4, the salvage component 5 moves, so that the fixed shaft 55 moves along the surface of the salvage plate 51 under the action of the chain. At this time, the bottom limit piece 562 shuttles inside the support frame 53, and the leaves and animal carcasses covered on the surface of the multiple groups of support frames 53 are clamped on the upper and lower parts of the leaves and animal carcasses respectively under the action of the eight groups of bottom limit pieces 562 moving upward, and under the action of the bottom limit pieces 562 and the salvage pieces 563, so as to fully salvage the leaves and animal carcasses and avoid the occurrence of salvage failure.
