The rotary reverse fishing type grid dirt remover can reduce the cost of post-waste residue treatment and can also avoid the problem of environmental pollution. The grid brings sundries to the upper part of the slag hole from bottom to top, the sundries fall off by gravity or water flow impact to the slag hole, and then fall into the conveyor from the slag hole to be discharged.
Because a certain distance exists between two adjacent groups of rake teeth on the rotary reverse-fishing type grid dirt remover, sundries in sewage are easy to flow away along with the sewage from the distance between the two adjacent groups of rake teeth, and therefore, an underwater auxiliary grid is usually arranged below the rotary reverse-fishing type grid dirt remover. The underwater auxiliary grating is required to be movable, namely, when the underwater movable auxiliary grating intercepts underwater sundries, the underwater movable auxiliary grating is pushed by the previous group of the harrow teeth to rotate, and after the previous group of harrow teeth are separated from the underwater movable auxiliary grating, the underwater movable auxiliary grating is required to be reset to the original position, so that the underwater movable auxiliary grating can be connected with the next group of harrow teeth. At present, the automatic resetting effect of the underwater movable auxiliary grid is poor, even the situation that the underwater movable auxiliary grid is difficult to reset due to overlarge rotating angle occurs, and at the moment, underwater sundries are easy to flow away along with sewage from the space between the underwater movable auxiliary grid and the adjacent two groups of rake teeth. When failing to reset in time, if manual resetting is carried out on the underwater movable auxiliary grid manually, the use of the grid dirt remover can be influenced, the working efficiency is influenced, and meanwhile, the operation risk and the cost are increased.

Detailed Description
The present invention will be described in further detail with reference to the drawings, but the scope of the invention is not limited thereto.
As shown in fig. 1-2, the automatic resetting device for the underwater movable auxiliary grid of the rotary reverse fishing type grid dirt remover comprises a front baffle plate 3 fixed below a dirt remover main body 6 and the underwater movable auxiliary grid 1 rotatably connected with the front baffle plate 3 through a hinge 4. The main body 6 of the dirt remover is an existing rotary reverse-fishing type grid dirt remover, the principle of the dirt remover is that a toothed harrow is fixed on a chain, under the drive of a motor reducer, a harrow tooth 7 rotates along with the chain in the reverse water flow direction, sundries are brought to the position above a slag hole from bottom to top, and the rear sundries fall off by gravity or water flow impact falls off to the slag hole.
