An adjustable river channel sediment removal device for drag suction boats

Abstract

The invention discloses an adjustable river channel sediment removal device used for a raking suction ship, and relates to the field of dredging equipment. The invention includes a rake shell and a movable cover. The movable cover includes a connecting shell and a working shell. One side of the connecting shell is fixedly connected with one side of the working shell. The connecting shell is located inside the rake shell and is opposite to the rake shell. The side walls are connected in rotation; the top outer arc surface of the working shell is fixedly equipped with a power mechanism; the inside of the working shell is installed with a crushing mechanism, and the power mechanism drives the crushing mechanism to rotate through two sets of transmission mechanisms; the working shell is far away from the connecting shell. A plurality of rake teeth are uniformly distributed and fixed on the side edges, and two lugs are symmetrically fixed on the side walls of both ends of the working shell; the lugs are provided with straight grooves. The invention utilizes the energy of the water flow to make the power mechanism drive the crushing mechanism to rotate through the transmission mechanism, so as to realize the crushing of the dredged material, avoid the damage of the rake teeth and the blockage of the suction pipe, and improve the dredging efficiency of the rake suction vessel.

Description

technical field [0001] The invention belongs to the field of dredging equipment, and in particular relates to an adjustable river channel sediment removal device for a suction boat. Background technique [0002] A suction boat is a dredging device that sucks mud while sailing, and the structure of the head of the suction boat has a direct impact on the dredging performance of the head, which is not only related to the production efficiency of the suction boat, but also related to the dredging performance of the suction boat. job security. Due to the long-term accumulation, the environment at the bottom of the river is complicated. There are some hard dredged objects on the bottom of the river. The long-term contact between the rake head and the hard objects will damage the rake head. If it cannot be broken effectively, it will directly affect the suction efficiency of the suction pipe, and even block the suction pipe. [0003] Therefore, it is necessary to study an adjusta...
