Description

Bucket wheel submersible dredge pump dredger

The utility model relates to excavation, dredging technology field, especially relates to a kind of mechanically operated having and digs the dredger of inhaling feedway.

In the prior art, what be used for training of channel work has cutter suction dredger and adopts chain bucket or the dredger of grab bucket pattern, cutter suction dredger exists the not high defective of efficient, and the mud that the dredger of chain bucket or grab bucket pattern digs out can not be carried at a distance, maybe need to carry through secondary, increase the construction trouble, the recently domestic dredger of developing a kind of reamer chain bucket combination, (China's utility model patent, patent No. ZL95200779.7), but still need secondary to carry though this dredger can improve a little work efficiency.Abroad, as West Germany Ao Lunsitaiyinkao Bell Co. on the basis that absorbs line cutter and chain bucket advantage, a kind of bucket wheel suction dredger of development, its work efficiency improves 1.4-2 doubly than strand suction formula, but this dredger adopts seat formula dredge pump, and all be large-scale, power is than high, complicated in mechanical structure, the dredging in cost height, inapplicable small-sized river course.

The purpose of this utility model is that a kind of structure that provides for a large amount of network of waterways, the rural area work of desilting and dredging of adaptation China is simple, cost is low, efficient is high, concentration is high, the bucket wheel submersible dredge pump dredger that can carry at a distance.

The technical solution of the utility model is such: a kind of bucket wheel submersible dredge pump dredger, comprise hull, registration device, engine installation, control mechanism, move ship mechanism, excavating gear, suction mud mechanism etc., wherein excavating gear adopts the bucket wheel form, bucket wheel is installed in and stretches out in the outer bucket wheel frame end of fore, bucket wheel frame is vertically moved by playing the frame suspension rod by the frame winch that rises that is installed on the deck in ship structure, its side travel is to handle hull by the bitubular winch that is installed on the cabin front portion all around to be shifted, thereby guarantees the correct location of mining position; The transmission of bucket wheel is to be realized through parts such as universal drive shaft and cone gears by worm reducer by the buncher that is installed on the bucket wheel frame; The periphery of bucket wheel is the no bed mud bucket that evenly gathers, and is cut the soil layer that the gets off sucking hole over against diving slurry pump by bucket wheel, mud under pump waterpower field action by ducting to the stacking place.

The utility model compared with prior art since bucket wheel to cut the mud performance good, under same power, force of cut is twice than reamer.The bucket of bucket wheel is laid very close, earth can only enter mud pump in the same crack between the bucket lip intake chamber, and the soil layer that cuts is thin and even, is difficult for stopping up the impeller of sucking hole and pump, has improved the efficient of pump.Bucket wheel cuts the mud layer that gets off and directly falls into pump intake, and the earth loss is less, concentration is high.No matter transverse moving left and right or digging depth change, and the excavation amount all changes down.And simple in structure, yardstick is less, cost is lower, be widely used in desilting and dredging of the network of waterways, China rural area.

By accompanying drawing the utility model is further described below:

Accompanying drawing 1 is a structural representation of the present utility model.

Accompanying drawing 2 is the structural representation of the utility model parts 14 bucket wheel drivings device.

From accompanying drawing 1 as seen: bucket wheel submersible dredge pump dredger of the present utility model, comprise hull, registration device, engine installation, control mechanism, move ship mechanism, excavating gear, suction mud mechanism etc., its registration device by hull 10 afterbodys about two work piles 1 and the stake winch 2 that rises that is installed on the deck in ship structure reach a suspension rod 3 and formed; Engine installation is the diesel powerplant 4 that is installed on the cabin rear portion; Control mechanism comprises the low-tension distribution board 5 of the control propulsion source that is installed on cabin middle part, submersible machine control housing 6, and the transmission of control bucket wheel, bucket wheel frame lifting and hull move and locate etc. the operating console 7 of function; Moving ship mechanism mainly is the bitubular winch 8 that is installed on the cabin front portion, excavating gear adopts the bucket wheel form, bucket wheel 17 is installed in the end of Shen for the outer bucket wheel frame 14 of fore, its driving device 13 is located on the bucket wheel frame, bucket wheel frame is vertically moved by playing a frame suspension rod 11 by a frame winch 9 that is installed on the deck in ship structure; Suction mud mechanism is mounted in the diving slurry pump 15 in the bucket wheel frame outside, and its sucking hole 16 is installed in the lip of bucket wheel, accepts and cuts the earth that falls, and is transported to by dredging tube 12 and stacks the place.

From accompanying drawing 2 as seen, the driving device of bucket wheel comprises buncher 17, and parts such as worm reducer 18 and universal drive shaft 19 and conical insert roller box 20 are formed.
