Embodiment Construction
[0011] The present invention will be described in detail below in conjunction with accompanying drawing: Figure 1-2 As shown, a dredging device for a dredging ship according to the present invention includes a dredging pump 1 and a twisted suction head 2 connected with the dredged pump 1, and the twisted suction head 2 includes a rotatable shaft and a Connected blades, the bottom of the sand pump 1 is connected to the twisted suction head 2 through a suction pipe 3, and a sundry blocking device 4 is arranged between the suction pipe 3 and the twisted suction head 2. The control device 4 is two hollow spheres with the same spherical center. The mud can pass through the gap between the two hollow spheres, but the debris with a large length or volume cannot pass through the gap, which effectively prevents the debris from blocking the suction pipe. Reduce maintenance times and maintenance costs; the top of the sand pump 1 is provided with a mud outlet pipe 5 extending into the pu...

The invention discloses a dredging device for the dredging ship. The device comprises a silt pump and a twisting head connected with the silt pump, the twisting head comprises a rotating shaft can rotate and a blade is connected with the rotating shaft, the bottom of the silt pump is connected with the twisting head through a suction pipe, a sundries blocking device is arranged between the suctionpipe and the hinge suction head, the impurity blocking device is a hollow sphere with two concentric spheres, the slurry can pass through the gaps between the two hollow spheres, the length or the large-size sundries cannot pass through the gap, a mud outlet pipe extending into the pump body and a vent pipe for allowing compressed air to enter are arranged at the top of the silt pump, one end ofthe vent pipe is connected with the silt pump, the other end of the vent pipe is connected with an air compressor, after the air compressed by the air compressor enters the silt pump, and the mud is discharged along the mud outlet pipe under the pressure of compressed air. The device is simple in structure, easy and convenient to operate, high in working efficiency, economical, practical, low in using noise and the like.
Description
technical field [0001] The invention relates to the technical field of river cleaning, in particular to a dredging device for a dredging ship. Background technique [0002] With the rapid development of my country's economy, the shipping industry has also accelerated its development, and the importance of waterways has become increasingly prominent. However, after the river course has been used for a long time, more silt will accumulate at the bottom. At this time, the silt needs to be cleaned to prevent the normal operation of the boats on the river course from being affected. In addition, our inland rivers also carry a large amount of silt, which often leads to silting of the river and obstruction of the waterway. Therefore, the importance of dredging ships is self-evident. How to quickly, efficiently and economically remove sludge has become a new problem. Therefore, there is an urgent need in the industry for a dredging vessel that integrates multiple advantages such ...
