Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-4 , the present invention provides a rotary grille cleaner, including a cleaner body 1. Sleepers 2 are fixedly installed on both sides of the frame of the cleaner body 1, and a rake frame 3 is arranged in the middle of the cleaner body 1. A plurality of groups of rake teeth 34 are evenly arranged on the rake frame 3, and upper connecting columns 31, middle connecting columns 32 and lower connecting columns 33 are evenly installed on the rake teeth 34. At the same time, adjacent two groups of rake teeth 34 are connected by the upper connecting column 31, the middle connecting column 32 and the lower connecting column 33; the rake teeth 34 include a tooth plate 341, and a rake seat 342 is fixedly arranged at the end of the tooth plate 341. At the same time, two groups of mounting holes 343 are opened on the rake seat 342, and the top of the tooth plate 341 is fixedly connected to the tooth end 348. A plurality of groups of sawteeth 349 are evenly arranged on the inner wall surface of the tooth end 348.

[0027] Working principle: The bottom of the cleaner body 1 is inserted into the water body, and at the same time, a plurality of rake frames 3 thereon move to convey and clean the sundries in the water body. A plurality of groups of equally spaced rake teeth 34 are installed on the rake frame 3. The sawteeth 349 are arranged in five groups and evenly distributed on the arc inner wall surface of the tooth end 348. The setting of the sawteeth 349 enables the sundries to stay stably on the rake teeth 34 after being grabbed by the rake teeth 34 and not easy to slide off; when the rake teeth 34 lift the sundries, enough force will be applied to hold the sundries tightly to prevent them from falling due to the action of gravity.

[0028] As a preferred implementation mode, the two sleepers 2 are symmetric structures with respect to the rake frame 3, and the surface height of the sleepers 2 is greater than the top height of the rake frame 3.

[0029] As Figure 1 shown: The surface height of the sleeper 2 is greater than the top height of the rake frame 3, so that when the cleaner body 1 is transported, the sleeper 2 can protect the rake frame 3 and prevent the rake teeth 34 on the rake frame 3 from deforming under the external pressure.

[0030] The toothed plate 341 is a fan-shaped structure made of metal, and three groups of arc-shaped reinforcing ribs 344 are arranged on both side surfaces of the toothed plate 341.

[0031] As a preferred embodiment, five groups of saw teeth 349 are evenly distributed on the arc-shaped inner wall surface of the tooth end 348, and the cross-section of the saw teeth 349 is triangular.

[0032] Upper perforations 347, middle perforations 346 and lower perforations 345 are respectively formed on the surface of the tooth end 348 from top to bottom, and lower connecting columns 33, middle connecting columns 32 and upper connecting columns 31 are respectively inserted into the lower perforations 345, middle perforations 346 and upper perforations 347.

[0033] The tooth end 348 is arranged in a "C" shape, and the top of the tooth end 348 is arc-shaped. At the same time, the tooth end 348 is fixedly connected to the handle base 342 through the toothed plate 341.

[0034] As Figures 2-4 shown: A large number of rake teeth 34 are fixedly connected through the lower connecting columns 33, middle connecting columns 32 and upper connecting columns 31. The arrangement of the three groups of connecting columns can block the lifting blind area formed between the rake teeth 34 and the rake teeth 34, improve the area for the rake frame 3 to lift sundries, and at the same time increase the compressive strength of the rake teeth 34.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
