[0098] like Figure 3 As shown, in one embodiment, the stirring device 4 comprises:

[0099] A stirring box 41, wherein the stirring box 41 is fixedly connected to a side end of the fixed pipe 35 near the cover body 36 through a bracket;

[0100] A double-headed motor 42, wherein the double-headed motor 42 is vertically fixedly connected to the stirring box 41, and the bottom end of the double-headed motor 42 is passed through the bottom end of the stirring box 41;

[0101] A stirring shaft 43, wherein the stirring shaft 43 is connected to the bottom end of the double-headed motor 42;

[0108] A first rope winding wheel 49, wherein the first rope winding wheel 49 is fixedly connected to the rope winding wheel fixing groove 48 via a second rotating shaft;

[0109] A rotating gear 40, wherein the rotating gear 40 is coaxially connected to the second rotating shaft with the first rope winding wheel 49;

[0110] A sliding seat 51, wherein the sliding seat 51 is slidably connected to the inner wall of the stirring box 41, and the sliding seat 51 covers the notch of the rope winding wheel fixing groove 48;

[0111] A transmission rack, the transmission rack is connected to the notch end of the sliding seat 51 close to the fixed groove 48, and the transmission rack is meshed with the rotating gear 40;

At this time, under the action of centrifugal force, the centrifugal ball 57 connected to the top of the double-headed motor 42 through the connecting rope slides on the inner end of the inclined plate 47. As the speed of the double-headed motor 42 increases, the opening angle between the connecting rope and the top of the double-headed motor 42 becomes larger, thereby pressing the inclined plate 47 to flip in the inclined plate fixing groove 46 toward the inner wall of the stirring box 41 with the first rotating shaft as the center, thereby pressing the sliding seat 51 connected to the inclined plate 47 through the rotating rod 52 to move upward along the inner wall of the stirring box 41 at the notch end of the rope winding wheel fixing groove 48, and the transmission rack connected to the bottom end of the sliding seat 51 drives the second gear 40 to rotate through the rotating gear 40. The rotating shaft rotates in the rope wheel fixing groove 48, and the first rope wheel 49 connected to the second rotating shaft pulls the first slider 54 to move upward in the first slide groove 53 through the first rope body 56, thereby driving the inner wall of the stirring cover 45 connected to the first slider 54 to move upward along the side end of the stirring box 41, and the stirring blade 44 is exposed in the stirring cover 45, thereby completing the stirring of the riverbed silt. When the double-headed motor 42 stops working, the reset coil spring 55 drives the second rotating shaft to rotate in the opposite direction, and the inclined plate 47 flips in the inclined plate fixing groove 46 away from the inner wall of the stirring box 41 with the first rotating shaft as the center, and the inclined plate 47 returns to its original state, and the first rope wheel 49 releases the pull on the first rope body 56, and the stirring cover 45 falls, thereby keeping the stirring blade 44 from being exposed in the non-working state.
