Submerged dredging machine

Abstract

The submersible river-desilting dredging machine is characterized by that its motor and mud pump are placed in a sealed shell body, the output shaft of said motor is connected with the mud pump by means of speed-changing gear box, and a power shaft which is perpendicular to the output shaft of motor is set between the motor and mud pump, the power shaft is matched with speed-changing gear box, and its two ends are equipped with symmetrical eccentric wheels, and the mud pump is placed on the chassis of the shell body, and the outer side of working surface of the chassis is covered with cutting filter screen, and the external end of sealed shell body is equipped with floating body. The invention is applicable to various river dredging engineerings.

Description

【Technical field】 [0001] The invention relates to a dredging device for dredging river channels for submerged operation. 【Background technique】 [0002] At present, the dredging devices for cleaning up riverbeds, ponds, artificial lakes and other silt debris mainly include hydraulic dredgers, dredgers and excavators. Hydraulic dredgers usually use high-pressure water guns to scour the soil, and then transport the mud to the destination by the mud pump supported on the floating barrel. Its advantage is that it can transport mud for a long distance. The disadvantage is that it must be cut off, and the labor intensity of the operator is high. , can not deal with stone fixed objects, resulting in low efficiency. The dredger can berth at a designated position on the water surface, install the mud pump on the liftable bridge frame, twist the mud into mud with a reamer, and transport it to the destination after being sucked by the mud pump on the bridge frame. The distance is lon...

Problems solved by technology

Hydraulic dredgers usually use high-pressure water guns to scour the soil, and then transport the mud to the destination by the mud pump supported on the floating barrel. Its advantage is that it can transport mud for a long distance. The disadvantage is that it must be cut off, and the labor intensity of the operator is high. , can not deal with stone fixed objects, resulting in low efficiency

The dredger can berth at a designated position on the water surface, install the mud pump on the liftable bridge frame, twist the mud into mud with a reamer, and transport it to the destination after being sucked by the mud pump on the bridge frame. The distance is long, the disadvantage is that the excavation depth and angle of the lifting bridge arm are limited, and the investment is large, the cost of use is high, the movement is inconvenient, and it is not suitable for small rural rivers, etc.

Excavators are common equipment. During operation, the chassis is on the shore, and the excavating arm is extended into the water. Its advantage is high excavation efficiency. The disadvantage is that it must be used in conjunction with other transportation auxiliary equipment such as transport vehicles, and it is prone to secondary pollution, and the scope of operation is limited. , large investment, high cost of use

Furthermore, none of these dredging devices are suitable for deep water operations
