Detailed Description

The technical solutions of the present invention will be further described below with reference to the accompanying drawings and examples in order to more clearly understand the technical solutions of the present invention.

Example 1:

as shown in fig. 1-2, the grille flushing device for the fine grille of the utility model comprises a mounting frame 2, wherein the mounting frame 2 is arranged below the top end position of a transmission chain of the fine grille 1; the mounting frame 2 is sequentially provided with a water spraying assembly and a hairbrush assembly from top to bottom; the water spraying assembly comprises a guide rod 3 and a threaded rod 4 which are arranged on the mounting frame 2, a moving block 5 which is sleeved on the guide rod 3 and the threaded rod 4, a liquid distribution pipe 6 which is arranged on one side of the moving block 5 close to the fine grating 1, and a plurality of spray heads 7 which are distributed on the liquid distribution pipe 6; the moving block 5 is connected with the guide rod 3 in a sliding mode and is in threaded connection with the threaded rod 4; the liquid distribution pipe 6 is communicated with a high-pressure water source through a pipeline; the spray head 7 is arranged towards the grating plate; two ends of the threaded rod 4 are rotatably connected with the mounting rack 2, and two ends of the threaded rod extend out of the mounting rack 2; one end of the threaded rod 4 is connected with an output shaft of a motor 13 arranged outside the mounting frame 2; the brush component comprises a rotating shaft 8 which is rotatably connected to the mounting frame 2, and bristles 9 which are arranged on the circumferential surface of the rotating shaft 8 and used for cleaning the grating plate; one end of the rotating shaft 8 extends out of the mounting frame 2 and is connected with the threaded rod 4 through a belt in a transmission mode.
