A combined river dredging device

Abstract

The invention discloses a combined river channel dredging device, which relates to the technical field of channel engineering cleaning. The invention includes a boat, a working box, a sludge tank and a dredging pump; two pairs of chutes are arranged on the inner walls of both sides of the working box; movable plates are slidably connected to the inner walls of the two pairs of chutes; through holes are opened between the two pairs of chutes; A pair of rectangular strips are arranged on both edges of the through hole; threaded holes are arrayed on one end of a pair of rectangular strips; the inner wall of the threaded hole is threaded with bolts; the bolts are matched with nuts; the upper surface of the work box is provided with round holes and installation holes; A dredging pump is fixedly installed on the inner wall; one end of the dredging pump cooperates with the sludge tank; two pairs of rotating devices are arranged on the upper surface of the working box; the inner wall of the working box is fixedly connected with the sludge tank; the working box is fixedly connected with the boat. The invention has the effects of convenient operation, cost saving, continuous operation, improved work efficiency and reduced labor intensity through the functions of the boat, the work box, the sludge tank and the dredging pump.

Description

technical field [0001] The invention belongs to the technical field of river channel engineering cleaning, in particular to a combined river channel dredging device. Background technique [0002] The main function of the river course is drainage and navigation. As time goes by, silt on the river bed will gradually accumulate; over time, the river bed will be raised, which will affect the navigation and drainage capabilities. It is black and smelly, which affects people's health; therefore, every once in a while, some rivers need to be dredged; the existing dredging method is mainly to build dams along the river in sections, and divide The water is drained, and then the river bed is flushed with a high-pressure water gun, and then the mud-water mixture is sucked into the nearby ditches or ponds through the suction pump. This dredging method consumes a lot of energy and costs a lot, and it is difficult to carry out continuous operations and has low working efficiency. Low. ...
