Dredging loader for water sump

Abstract

The invention discloses a dredging loader for a water sump, which mainly comprises a scraper conveyor, a cleaning guard plate connected with the tail part of the scraper conveyor and a walking trolley loading the scraper conveyor, wherein the cleaning guard plate consists of protection plates, screw impellers arranged on the inner sides of the protection plates and cleaning rubber sheets fixed below the protection plates; the protection plates are connected with the front end of a connection plate through a longitudinally horizontal pin shaft; the connection plate is connected with the tail of the scraper conveyor through upper and down vertical hinge pins; left and right push-and-pull hydrocylinders are arranged between the outer side of each protection plate and the tail of the scraper conveyor; upper and down push-and-pull hydrocylinders are arranged between the protection plates and the connection plate; and a curving elastic rubber and plastic conveying scraping plate is arranged on a chain of the scraper conveyor. The adoption of the dredging loader relieves the labor strength of workers greatly, saves the time, completely avoids the phenomenon of leaking coal slime in the water sump during artificial dredging, increases the effective capacity of the water sump and ensures that a drainage system is performed normally and sequentially, so that the normal safety production of mines is ensured.

Description

Technical field: [0001] The invention relates to a dredging mechanical device, in particular to a water tank dredging loader used for cleaning coal slime in a mine underground water tank. Background technique: [0002] There is a large amount of groundwater in the process of underground coal mining, and the mine drainage system undertakes the important task of draining the underground water, which is the key link to ensure the safe production of the mine. In order to facilitate drainage, several water bins need to be arranged under the coal mine, and each water bin is provided with a pair of water bins, that is, the inner and outer water bins are used for water storage. When the underground water flows to the water tank, a part of coal slime and sediment are brought into the water tank to settle in the water tank, which hinders the storage of the water tank, so it must be cleaned and excavated in time. Article 281 of the "Coal Mine Safety Regulations" stipulates that the wa...
