Dredging head for underwater dredging machine

Abstract

The invention provides a dredging head for an underwater dredging machine, and relates to the field of underwater dredging. The dredging head for the underwater dredging machine comprises a silt pumping pipe and a motor, the exterior of the upper end of the silt pumping pipe is fixedly sleeved with a supporting sleeve, the motor is fixedly connected with the left side face of the supporting sleeve, the exterior of the lower end of the silt pumping pipe is fixedly sleeved with a fixing sleeve, and the circumferential face of the silt pumping pipe is fixedly sleeved with a sealing disc. The circumferential face of the sealing disc is fixedly connected with the inner wall of the fixing sleeve, a water drainage hole communicated with the interior of the fixing sleeve is formed in the position, located above the sealing disc, of the circumferential face of the fixing sleeve, a plurality of water inlet holes communicated with the interior of the fixing sleeve are formed in the bottom end of the fixing sleeve, an installation disc is fixedly installed at the upper end of the fixing sleeve, and the exterior of the installation disc is sleeved with a sliding disc. According to the dredging head for the underwater dredging machine, the motor is arranged, the motor can rotate through meshing of the gear and a rotating wheel when rotating, the efficient silt pumping effect is achieved, and the problem that an existing dredging head is affected by hard silt and thus is low in dredging efficiency is solved.

Description

technical field [0001] The invention relates to the field of underwater dredging, in particular to a dredging head for an underwater dredging machine. Background technique [0002] Our country has a vast territory, with many rivers, reservoirs, and power stations, all of which are responsible for drinking, flood discharge, drainage, tourism, shipping, power generation and other different functions for the blood of our lives. However, silt often forms silt when it collects into rivers and reservoirs with water flow, and silt can easily cause river channel blockage and seriously affect the use function of the river channel. In order to slow down the siltation and prolong the life of the reservoir, it is usually necessary to use mechanical excavation to clean up the underwater silt, among which the underwater dredger is an important mechanical equipment. [0003] Although some existing dredging heads can clean hard silt, the underwater environment is relatively complex, and mo...
