Description

TECHNICAL FIELD

[0001] The utility model mainly relates to the water area dredging equipment field, concretely is a river course dredging device. BACKGROUND

[0002] River course silt cleaning is a way of river course management, and river course dredging can deepen the river course, benefit drainage, flood discharge, purify water quality, and is relatively common in daily life. In the process of soaking and water flow for many years, a large amount of silt deposition is generated on the riverbed at the bottom of the river course. If it is not cleaned for a long time, the riverbed of the river course will be raised, and the water storage capacity will be reduced. Therefore, it is necessary to regularly carry out dredging operation on the river course.

[0003] However, the existing river course dredging device is generally fixed on the shore or the ship body, and the dredging depth cannot be flexibly adjusted during use. Moreover, the fixed dredging device makes it difficult for the dredging ship to travel, and the dredging device is generally closed and always underwater, which causes certain difficulties in internal cleaning and maintenance. UTILITY MODEL CONTENT

[0004] To solve the problems of the prior art, the utility model provides a river course dredging device, which has the following main effects. A movable support plate driven by screw rotation is arranged in the ship body to move and drive the dredging pipe barrel to move. A hydraulic cylinder capable of driving the dredging pipe barrel to lift is arranged between the movable support plate and the dredging pipe barrel. The dredging pipe barrel is moved to the rear of the ship body and lifted at the front end, so that the lower end of the dredging pipe barrel is inserted below the water surface. The dredging depth can be adjusted by adjusting the lifting height of the movable support plate and the hydraulic cylinder. A spiral conveying blade driven by a motor is arranged inside the dredging pipe barrel to convey the silt and impurities accumulated at the bottom of the river course to the upper part of the dredging pipe barrel. A drainage pipe and a guide pipe are arranged on both sides of the dredging pipe barrel to convey the silt and impurities to the two ship bodies for collection. After dredging is completed, the dredging pipe barrel can be retracted into the ship body. The dredging pipe barrel is divided into two parts and connected by bolts. When the inside of the dredging pipe barrel needs to be cleaned, the dredging pipe barrel can be placed on the ship body and opened to clean the inside of the dredging pipe barrel.
