Position adjustable dredging device

Abstract

The invention relates to the technical field of river and lake dredging, in particular to a position adjustable dredging device. The position adjustable dredging device comprises a delivery pipe, a suction pump communicating with the upper end of the delivery pipe and a taper hopper communicating with the lower end of the delivery pipe, and further comprises a rectangular frame fixed to the two sides of a ship body, a sliding platform in sliding fit with the rectangular frame, a winch, a mechanical arm and a counterweight. The sliding direction of the sliding platform is consistent with the length direction of the ship body. The winch is fixed to the sliding platform. The counterweight is suspended onto the winch through a wire rope. The fixed end of the mechanical arm is fixedly connectedwith the counterweight. The movable end of the mechanical arm is fixedly connected with the lower end of the delivery pipe. The upper end of the delivery pipe and the suction pump are both fixed to the sliding platform. At the upper end of the delivery pipe, the dredging device is controlled to conduct wide-range position adjustment through sliding connection of the rectangular frame and the sliding platform to improve the dredging efficiency. The dredging device is controlled to conduct small-range accurate positioning through the mechanical arm hoisted by the winch so that the taper hoppercan avoid plants at the river bottom and protect the plants.

Description

technical field [0001] The invention relates to the technical field of river and lake dredging, in particular to a position-adjustable dredging device. Background technique [0002] Each river and lake is an independent ecological circle. In order to ensure the cleanliness of the environment, the bottom of the river and lake should be regularly dredged. However, due to the huge workload of dredging, mechanical equipment will be used to clean it. Most of the traditional cleaning equipment is conveyed by the conveyor belt or sucks the sludge directly through the suction pipe. When the position needs to be changed, the hull is directly moved. Due to the large volume of the hull, moving the hull directly will cause the distance between the suction positions to be too large, resulting in poor dredging effect. At the same time, due to the inability to achieve fine position adjustment, it is easy to touch the vegetation at the bottom of the river during dredging, which will not on...

AI Technical Summary

Problems solved by technology

Due to the large volume of the hull, directly moving the hull will make the distance between each suction position too large, resulting in poor dredging effect

At the same time, due to the inability to achieve fine position adjustment, it is easy to touch the vegetation at the bottom of the river during dredging, which will not only cause damage to the vegetation at the bottom of the river, but also reduce the dredging effect at this position
