Environment-friendly riverway sludge excavation device

Abstract

The invention discloses an environment-friendly riverway sludge excavation device. The environment-friendly riverway sludge excavation device comprises an excavation barrel, a connection barrel, anoperation rod, a connection rod and excavation buckets; the top end of the excavation barrel fixedly communicates with the connection barrel; the operation rod is in threaded connection with the innerside of the connection barrel, and the bottom end of the operation rod is fixedly provided with a reducing sleeve which is arranged to be a sleeve pipe of a semi-closed structure; the bottom end of areducing block is fixedly provided with a connection rod; the connection rod is arranged on the inner side of the excavation barrel in a sleeved mode, and the two sides of the connection rod are fixedly provided with limiting blocks correspondingly; the positions, opposite to the limiting blocks, of the inner side of the excavation barrel are fixedly provided with limiting grooves, and the limiting blocks are slidably connected to the inner sides of the limiting grooves; the bottom end of the connection rod is fixedly connected with two first hinged seats; and the excavation buckets are rotationally connected to the inner sides of the first hinged seats correspondingly. Through the environment-friendly riverway sludge excavation device, the problem that sludge goes away due to the fact that shaking is large in the bottom sludge lifting process during sludge removal excavation is solved.

Description

technical field [0001] The invention relates to the technical field of river silt cleaning devices, in particular to an environment-friendly river silt digging device. Background technique [0002] At present, the vast majority of rivers in my country suffer from water pollution to varying degrees. Part of the pollution factors are eliminated through self-purification and degradation of the water body, and some refractory substances, such as heavy metals or pollutants that exceed the self-purification capacity of the environment, are deposited on the riverbed through a series of migration and transformation. The pollution of river bed sediment has increased. Therefore, it is necessary to understand the pollution status and changes of water bodies through investigation and sampling, find out the migration status of sediment and the process of pollutant accumulation and change, grasp the pollution of river sediment, and take corresponding control measures. [0003] There are f...
