Deep mine clearing and digging device

Abstract

The invention relates to a mechanical device for cleaning up dregs under sewage wells, in particular relates to a deep well excavation cleaner which is suitable for cleaning up the dregs in sewage wells in a draining system. The deep well excavation cleaner comprises a box lever, a clamshell excavator composed of two buckets which can open or close relatively, and a clamshell excavator cylinder used to control the two buckets to open or close. The box lever is composed of an external box, a middle box which is driven and connected through the telescopic cylinder of the box lever and can slide along the external box, and an internal box which can slide along the middle box. A descending pulley is arranged at the lower part of the middle box; two ends of a descending steel wire which goes round the descending pulley are respectively fixed at the upper end of the external box and the upper end of the internal box. A lifting pulley is arranged at the upper part of the middle box; a lifting guide pulley is arranged at the lower part of the external box; one end of a lifting steel wire is fixedly connected at the lower end of the internal box and the other end goes round first the lifting pulley and then the lifting guide pulley and finally is fixedly connected to the upper part of the external box; and the clamshell excavator is connected with the lower end of the internal box. The deep well excavation cleaner can avoid heavy physical labor for cleaning up the sewage wells and greatly improve work efficiency.

Description

technical field [0001] The invention relates to a mechanical device for cleaning and digging underground dirt, in particular to a cleaning and digging machine suitable for sewage wells and rainwater wells of underground drainage systems. Background technique [0002] The public facilities in modern cities are very complete, especially the underground drainage facilities in the city are dotted all over the underground of the city. These underground pipes must have a sewage well for cleaning pipes not far away, and some There are still many rainwater wells on the side of the road. These wells need to be used for a period of time to clean out the sand, gravel, silt and other sundries in order to ensure the normal use of the pipelines and these wells. At present, all these work are done manually. To carry out, not only low work efficiency, high labor intensity, bad working environment, but also difficult to clean up.
