Description

Semi-enclosed submerged suction dredge with self-twisting, self-sucking and self-advancing features

What the utility model provided is a kind of new underwater silt remover---semiclosed from twisting self-priming from the suction dredge of walking under water.Belong to agricultural machinery technological field.

The latent formula pond dredger that existing dredger such as Xinjing Machinery Factory, Shanghai produce, it has only suction nozzle to be furnished with to inhale the walking apparatus of seeing off, and its power is by submersible motor.Submersible motor cost height, humidity resistance is poor, the life-span is short, do not have in the suction nozzle strand mud device, concentration low, meet pan soil and can't construct.Also have some large-scale dredge boats, it partly is equipped with strand mud device at suction nozzle, is open type, laterally twists mud that mud twists and leans on the high-velocity flow at mouth piece place that mud is swept away, and concentration of hydraulic mixture has only 10%.

The purpose of this utility model be to propose a kind of whole machinery have complete automatic control, self-priming, certainly strand, from running gear.It is semi-enclosed from strand, self-priming, the suction dredge under water walked certainly.It runs into pan soil equally can operate as normal.Concentration of hydraulic mixture can be up to 80%.

Technical solution of the present utility model: its structure as shown in the figure.It mainly contains power, walking, strand mud and suction and send four systems.Wherein suction is sent system that slush pump is arranged and pipeline should be arranged.Slush pump is that what to adopt is prior art, and it is arranged on the afterbody near buoyancy aid, plays suction and send mud; Suction send system to also have soil-suction head, and it is to sink under water, and is connected with slush pump.Soil-suction head has coulter shaft and two augers and suction nozzle shell.There is driving shaft the power transfer part, and driving shaft is an enclosed major axis of more piece, and driving shaft is the umbrella gear box transmission by driven by motor work.Semiclosed soil-suction head and driving shaft join, and umbrella gear box and driving shaft join.Two augers drive by driving shaft in suction nozzle shell both sides.Two augers are the different spirals of rotation direction, and its turn direction also is incorgruous rotation, thereby order about buoyancy aid and contained apparatus marches forward.Upending frame is located at the buoyancy aid head, does not hang suction nozzle and hangs the water surface by wirerope when soil-suction head is not worked, and sinks under the water during work.Driving shaft is a closed more piece major axis that can change length.Driving shaft and suction nozzle join, and drive the auger and the coulter shaft work of suction nozzle part; Umbrella gear box is to join with belt and motor, and umbrella gear box is just by driven by motor work.Whole device has four motors, and a motor is to be used for promoting hanging work, and a motor is used for driving bevel gear and makes driving shaft work, also has a motor to be used for making upending frame work, and it passes through the driven by motor gearbox, by gearbox band rope roll.Slush pump itself also has motor, guarantees slush pump work.Three motors join with hanging, upending frame, umbrella gear box respectively by belt.Umbrella gear box drives driving shaft work, the work of drive shaft suction nozzle.Dynamical system mainly is four above-mentioned motors, and it also can use diesel engine instead as power.Running gear is to drive forward by two augers, and the course is held in hanging.Whole device adopts is that splicing structure, double width, plane buoyancy aid carry floating all machineries, is furnished with hanging and makes auxiliary propulsion, is shifted and turns round.The walking strand is inhaled power by closed more piece axle.From the suction nozzle gear-box under water that is passed to waterborne, gear-box drives coulter shaft and rotates in semi-enclosed suction nozzle shell, and 12 are twisted into dense mud to colter with mud on the coulter shaft.The slush pump suction inlet is connected by sebific duct with the suction nozzle shell, forms enclosed from strand, self-suction system.The different auger of direction of rotation is equipped with in the suction nozzle both sides, gear-box power transmits break-in, speed change through worm gear case and drives auger do not stop rotation in earth, make auger produce propulsive force in earth, auger promptly drives suction nozzle and the walking automatically of all machinery, forms complete automatic running gear.Automatic control electronic box and suction nozzle lifting crane is housed on the buoyancy aid, when suction nozzle quits work, dried up capable of hoisting.

Whole machinery have complete automatic control, self-priming, certainly strand, from running gear.Can construct in pan soil, concentration of hydraulic mixture can reach 80%.From waterborne to using closed more piece major axis transferring power under water.

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

Among the figure 1 is hanging, 2,5, the 6th, motor, the 7th, upending frame, the 3rd, slush pump, the 4th, umbrella gear box, the 8th, driving shaft, the 9th, transmission case, the 10th, auger, the 11st, case, the 12nd, worm gear case, the 13rd, coulter shaft.

Claims (1)

1, by suction give, that power, walking, strand mud four systems are formed is semiclosed from strand, self-priming, the suction dredge under water walked certainly, it is characterized in that inhaling soil-suction head in the mud system and be and sink under water and slush pump joins, it is made up of coulter shaft, two augers and suction nozzle shell, its two augers are located at suction nozzle shell both sides, make incorgruous rotation promotion hull and advance; Running part in the dynamical system is that the driving shaft that drives auger and coulter shaft work is arranged, it is an enclosed major axis of more piece, and join with semiclosed soil-suction head, the umbrella gear box that depends on motor-driven to go to drive driving shaft work joins with driving shaft, upending frame is located at the head of buoyancy aid, and hangs sink under the water work or hang the water surface of suction nozzle with wirerope.
