Dredger

Abstract

The invention discloses a dredger. The dredger comprises a dredger body, a sludge cleaning device and a propelling and positioning device; the sludge cleaning device comprises a plurality of rake tooth gratings, a plurality of sludge suction devices, a sludge delivering pipe and positioning floats; a first support and a second support are mounted at the front end of the dredger body; a first driving motor and a first chain wheel are mounted at the top end of the first support; the first chain wheel is mounted at the output end of the first driving motor; a plurality of electric hoists are mounted on the second support; each circle of rake tooth grating winds around a second chain wheel and a third chain wheel; each second chain wheel is connected with the first chain wheel through a firsttransmission belt; each third chain wheel is connected with the output end of the corresponding electric hoist; the sludge suction devices are connected with the sludge delivering pipe; the positioning floats are mounted on the sludge delivering pipe; and the propelling and positioning device is used for pushing the dredger body to move forwards or positioning the dredger body on the river bed. Bythe aid of the dredger, sludge in the river bed can be cleaned and recovered effectively, the sludge cleaning depth of the dredge is deep and adjustable, the river bed and the ecological system of the river bed cannot be damaged, and the influence on the river bed is small.

Description

technical field [0001] The invention relates to a river bed garbage cleaning device, in particular to a dredging ship. Background technique [0002] There is often a large amount of garbage deposited in the silt of the river bed, which causes damage to the environment and ecology. It is very necessary to clean up the silt and garbage on the river bed. CN106697207A discloses a river and lake surface silt garbage cleaning ship, which is divided into three parts: garbage bin, garbage bin, and power bin. The garbage bin is located at the bow, and a garbage entrance is opened at the bow, with a height of 70 cm and a width of 120 cm. Left and right, the center height of the garbage entrance is basically the same as the water surface, and a roller with a diameter of 60 cm can be installed above the inner side of the entrance, and the speed of the roller is 30 revolutions per minute. The lower arc of the roller is connected to the water surface, and the roller is driven by the motor...

CN106697207A discloses a river and lake surface silt garbage cleaning ship, which is divided into three parts: garbage bin, garbage bin, and power bin. The garbage bin is located at the bow, and a garbage entrance is opened at the bow, with a height of 70 cm and a width of 120 cm. Left and right, the center height of the garbage entrance is basically the same as the water surface, and a roller with a diameter of 60 cm can be installed above the inner side of the entrance, and the speed of the roller is 30 revolutions per minute. The lower arc of the roller is connected to the water surface, and the roller is driven by the motor. Rotate counterclockwise to make the garbage on the surface of the water quickly enter the garbage bin. A mesh metal chain lifting belt is installed in the middle of the garbage bin. The lifting belt is 40 degrees from the horizontal plane and tilts to the rear of the ship. One end enters the water at a depth of 35 cm, and the other end exceeds the hull. The height is 90 cm, the width of the lifting belt is 60 cm, and a drain is opened on both sides of the rear of the garbage bin, so that the water entering the garbage bin is discharged from the drains on both sides, so that the garbage on the water surface can enter smoothly. In the middle seat of the ship, the garbage on the surface of the water falls into the garbage bin driven by the lifting belt. The power cabin is the rear part of the ship. An engine is installed in the middle of the power cabin to drive the propeller, and a water pump is installed on the right side to drain the water collected in the boat. , a power generation unit is installed on the left side to meet the power consumption of the motors on the ship. A movable cover is placed on the top of the power compartment, and the helmsman of the ship is at the stern. Requirements for Deep Cleaning of Riverbeds

CN2501916Y discloses a river bed rubbish cleaning machine, which is connected with a large frame by the hull, a hinged base connected with the large frame with the hull, a base level detection device and a base level adjustment device installed on the base, and a rolling hinge installed under the base. machine frame, the roller hinger installed in the middle of the roller hinger frame, the fender installed around the roller hinger frame, the garbage outlet opened on the rear fender, fixed in front of the roller hinger frame The water ejector at the bottom is composed of a transmission mechanism that connects the roller hinge with the power source. Although this river bed garbage cleaning machine can be used to clean river bed garbage, its cleaning depth is also shallow, and the cleaning effect is not ideal.
