Abstract

The utility model discloses a simple dredger for stream channel. A flat plate taken as a work platform is arranged on the buoy, and railings taken as the body of the ship of the dredger are arranged around the flat plate. The vacuum absorbing power of the sand absorbing device arranged on the ship body is utilized, the submarine river sand is absorbed into a sand-water separator by the sand absorbing tube, the flowing water is drained, and the damp sand is transported onto the sand transporting ship. The utility model has the advantages of simple structure, convenient installation and maintenance, small size, flexible operation, high efficiency, safe production, less manufacture cost, wide sand fetching channel, and stable ship body, being favorable for regulating the flatness of the river bed.

Description

Simple dredger for stream channel

The utility model belongs to the machine of digging sand in the simple and easy river course that the river course operation at sea takes water-bed river sand.

The sand device of getting of inland river dredge boat is to be fixed on the sprocket-type conveyer belt in the same direction uniformly by a plurality of buckets of digging sand, after conveyer belt connects from beginning to end, be enclosed within on the transverse axis of the runner that links to each other with reductor that is installed on the hull and elevator lower end, during work, the elevator lower end layer of sand that sinks under water, the start running, because dig sand bucket and conveyer belt synchronous operation, hull slowly advances, when the bucket of digging sand contacts with layer of sand, just river sand is dug in the bucket, the rising water outlet is poured the river sand in the bucket into cabin then.This whole heavy by getting the dredge boat that sand device running, sand hopper dig sand, involve great expense, invest big, and it is narrower to get the sand road of sand, it is bad to get the sand effect.

The purpose of this utility model is to provide a kind of bottom that is useful in the river course to get sand, all simple and easy very easily river course of the operating maintenance machine of digging sand.

The method that the utility model is finished is to make hollow pontoon with metal blank, flat board is installed as work top on floating drum, adds railing all around, the hull of forming dredge boat, the damp sand conveying device is installed, grit water separator, loading and unloading hoisting frame and suction sand device on the hull.The stirring of sinking to layer of sand when inhaling the sand device by sand suction pipe and work

Connect, utilize the strength of vacuum suction when digging sand, the loose river sand that stirs through agitator, in company with muddy water along sand suction pipe, absorb in the grit water separator that is installed on the hull from the bottom, drop removes flowing water, stay damp sand, with conveying device cargo ship is gone up in the damp sand commentaries on classics again and transported.Work finishes, and the wire rope that elevator utilizes the lower end to be connected with sand suction pipe is left the water agitator through the loading and unloading hoisting frame.

The utility model has the advantages that: 1. simple in structure, installation and maintenance are convenient; 2. replace with what sand hopper was dug sand and get the sand device with inhaling the sand device, volume is little, and manufacturing cost is few, uses maneuverability; 3. can dig sand more than 3000 cubic metres every day, it is effective to get sand; 4. the sand road of getting sand is wide, and it is smooth to help riverbed, whole station; 5. hull is steady, production safety.

Accompanying drawing is overall structure figure of the present utility model, and wherein Fig. 1 is a front view, and Fig. 2 is a vertical view.

Most preferred embodiment of the present utility model is flat board to be installed as working platform (3) on floating drum (1), railing (2) is installed all around, the hull of forming dredge boat, the general circuitous water of floating drum is not allowed the steel plate that gets rusty, volume roller welding is connected into hollow cylinder, the size of this hollow pontoon, how much are length and use number, all design definite according to the hull carrying capacity.Generally be no less than two floating drums, also can adopt the good material of buoyancy to make floating drum, hoisting frame ∥ (7) and elevator (8) are installed above the hull, the wire rope ∥ (15) that the elevator utilization links to each other, activity wheel through the hoisting frame top connects sand suction pipe (5), so that the agitator (6) that control is connected with the sand suction pipe lower end enters water-bed layer of sand when operation the degree of depth.Hang out the water surface when not working.Agitator comprises that automatic stirring and hydraulic pressure stir, and the effect of agitator enters sand suction pipe after being to make water-bed layer of sand loose.The upper end of sand suction pipe is connected with suction sand device (14) on being installed in hull, utilizes the strength of vacuum suction that agitator is smash the diffusing water-bed fluffing of moulding sand when inhaling the sand device busy and enters in the grit water separator (4) along sand suction pipe.Drop goes the damp sand behind the flowing water to forward on the sand carrier by conveying device (13).The leading portion of hull also is equipped with loading and unloading hoisting frame (9), is used for lifting by crane elevator, sand sucker.The loading and unloading maintenance of machinery such as grit water separator.The back segment of hull is equipped with power machine room (10), and driver's cabin is located at wherein, and the mobile reductor (11) that stern is installed utilizes the interconnect function of the pull rope (12) that the other end links to each other with water-bed anchor.Control the gait of march of machine when operation of digging sand.

Claims
