[0016] In order to enable the above-mentioned purposes, features and advantages of the present application to be more clearly understood, the present application will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0017] As Figures 1-6 shown in a kind of jet grab for cleaning gate sill silt, the jet grab includes grab frame 1, rotary rake device 2, high-pressure jet device.

[0018] Grab frame 1 is connected with lifting device through connector 101 in its top, facilitating the lifting and movement of grab, and the rear side of grab frame 1 is provided with guide wheel 102, so that guide wheel is pressed on the grid of trash rack or gate slot or grid slot, and plays the role of guiding and stabilizing.

[0019] The turning rake device 2 is hinged to the lower end of the grab frame 1, and is composed of a plurality of rake teeth 201 and a connecting frame 202. The plurality of rake teeth 201 are uniformly fixed on the connecting frame 202, and the connecting frame 202 is hinged to the grab frame 1. The turning rake device 2 is controlled to rotate by a hydraulic cylinder 3 hinged to the grab frame 1. The lower end of the turning rake device 2 is also provided with a shovel tooth 7 cooperating with the turning rake device 2. The opening and closing actions of the turning rake device 2 are realized by the extension and retraction of the hydraulic cylinder 3, so as to grab the silt.
