Cutter suction device used for sewage removal boat on river surface

Abstract

The invention discloses a cutter suction device used for a sewage removal boat on a river surface and relates to the field of silt removal equipment. The cutter suction device includes a reamer head connected to the end of a cutter suction pipe and comprises a fixing ring, a connecting sleeve and multiple reamer arms, the curved reamer arms are fixed between the fixing ring and the connecting sleeve, and multiple reamer teeth are uniformly and fixedly distributed on one side face of each curved reamer arm; each reamer tooth includes a toothed base and a reaming tooth, and the toothed bases areconnected with the reaming teeth through bolts. Each toothed base is of a cubic structure, one side face of each toothed base is fixedly connected with the side face of the corresponding curved reamer arm, and an oval groove is formed in the other side face of each toothed base; a blind hole communicated with the corresponding oval groove is formed in each toothed base, and a first spring is clamped into each blind hole. Through holes are symmetrically formed in the opposite side walls of each oval groove. By fixedly installing the reaming teeth in the toothed bases, under the cooperation ofthe first springs, straight groove openings and bolts, damping performance is provided for the reamer teeth, the efficiency of maintaining the reamer teeth is improved, and labor pressure of people isreduced.

Description

technical field [0001] The invention belongs to the technical field of dredging equipment, in particular to a cutter suction device used for river surface cleaning ships. Background technique [0002] When the cutter suction cleaning ship is working, it needs to stir up the sediment deposited on the bottom of the river and lake first, then use the mud pump to pump out the turbid solid-liquid mixture, and then filter the mixed sediment and discharge it to the designated It plays an important role in the dredging or removal of silt at the bottom of lakes, rivers, reservoirs, etc. [0003] However, the environment at the bottom of rivers and lakes is relatively complicated, and many large solids, such as stones, are often deposited. When the cutter suction boat is working, the cutter teeth do not have a buffer function and are in contact with large hard solids. It will bring huge damage to the reamer teeth, and the existing reamer teeth are fixed on the reamer arm and cannot b...
