Description

Technical Field

[0001] The present application relates to a reservoir dredging device. Background Art

[0002] In order to buffer the imbalance between the water use end and the water supply end, some reservoirs are generally set up to deal with this problem. For small reservoirs, manual dredging can generally be used, but for medium and large reservoirs, the cost of manual treatment is too high and the time is too long, so only mechanized treatment can be used. However, since the reservoir itself is completely different from the river channel and the area is not particularly large, it is difficult to use dredging equipment arranged in rows, and the procurement cost of this type of equipment is also relatively high, which is not suitable for widespread use in reservoir dredging. Utility Model Content

[0003] In order to solve the above problems, the present application proposes a reservoir desilting device, including a rotating motor, a vertically arranged stirring part connected to the power is arranged at the lower part of the rotating motor, a transition holding chamber is arranged at the upper part of the stirring part, and a discharge pipe is arranged on one side of the transition holding chamber; the stirring part includes a rotating shaft connected to the power of the rotating motor, an upper annular plate is arranged on the side of the rotating shaft, arc plates are evenly arranged at the lower part of the upper annular plate, and a plurality of crushing teeth are arranged on the arc plate. The present application adopts a vertically arranged stirring part, which occupies a relatively small space as a whole and has a relatively low cost, and is suitable for desilting the reservoir. The broken and stirred sludge first enters the transition holding chamber, and then is introduced from the transition holding chamber into the discharge pipe to complete the sludge cleaning operation.

[0004] Preferably, a feed guide screw is also provided on the outer side of the rotating shaft.

[0005] Preferably, a support head is arranged at the bottom of the rotating shaft, and a transition connection bearing is arranged between the support head and the rotating shaft.

[0006] Preferably, a receiving groove is provided on the inner side of the arc plate, and the crushing teeth include a clamping block embedded in the receiving groove, and a crushing cone is provided on one side of the clamping block facing the rotation direction of the stirring part to form the crushing teeth. The present application can prevent the re-precipitation of the dispersed sludge through the coordination of the arc plate, the gap formed between the arc plates, and the rotating shaft provided in the middle, thereby ensuring the dredging effect.

[0007] Preferably, the crushing teeth are arranged obliquely.

[0008] Preferably, a plurality of rotating parts are arranged on the upper portion of the upper annular plate, and an annular guide edge cooperating with the rotating parts is arranged on the outer side of the transition accommodating chamber.

[0009] Preferably, the rotating part includes a U-shaped bracket, a rotating wheel is arranged in the U-shaped bracket, and the rotating wheel is arranged to slide and abut against the annular guide edge. The present application can fully ensure the rotation stability during dredging through the coordinated arrangement of the rotating wheel and the annular guide edge, thereby ensuring the effect of breaking up the sludge.

[0013] 1. The present application adopts a vertically arranged stirring section, which occupies a relatively small space as a whole and has a relatively low cost. It is suitable for dredging operations in water reservoirs.
