Detailed Description

The utility model is further described with reference to the following figures and detailed description.

A variable-angle dirt-removing rake as shown in fig. 1 to 4, which comprises a telescopic arm 11 and a rake assembly movably connected with the telescopic arm 11; the telescopic arm 11 is connected with the tooth rake component through a rotary rake rotating shaft. The tooth rake component comprises a fixed tooth rake 23, a movable tooth rake 22 and a tooth rake rotating arm 21; the rotary harrow driving device 31 is used for driving the harrow teeth assembly to adjust the angle; a harrow drive device 32 used for driving the movable harrow 22 to make the movable harrow 22 and the fixed harrow 23 in a harrow combining state or a harrow separating state. When floaters in front of the trash rack are cleaned, the telescopic arm 11 conveys the rake tooth assembly above the floaters under the operation of the driving device, the rake combining driving device 32 drives the movable rake tooth 22 and the fixed rake tooth 23 to be in an open state, and the preparation for clamping the floaters is well made; in order to clamp the floating objects close to the trash rack better, the rotating arm 21 can be driven by the rotating harrow driving device 31 to rotate by taking the rotating harrow rotating shaft as the center of a circle, so that the angles of the movable toothed harrow 22 and the fixed toothed harrow 23 can be adjusted, and the floating objects can be clamped more conveniently.
