Abstract

The invention discloses a device for quickly cleaning frozen and stuck materials in an excavator bucket and the bucket, and belongs to the technical field of surface mining equipment. The device comprises a chain net and a fixing device. The chain net is a net structure formed by connecting a plurality of main chains and auxiliary chains in a cross mode and used for being clung to the inner wall of the bucket, and a plurality of fixed links are arranged on the chain net. The fixing device is connected with the fixed chain ring and is used for detachably fixing the chain net on the inner wall of the bucket. When the cleaning is carried out, the frozen and adhered material wraps the chain net, the zipper net is pulled outwards after the fixation is released, and the frozen and adhered material can be peeled off from the inner wall of the bucket along with the whole or large blocks of the chain net, so that the cleaning efficiency is greatly improved, and the labor intensity and the safety risk are reduced. The invention also discloses an excavator bucket comprising the device.

Description

Device for rapidly cleaning frozen and adhered materials in bucket of excavator Technical Field The invention belongs to the technical field of continuous mining major equipment of an open pit coal mine, and particularly relates to a device for quickly cleaning frozen and stuck materials in a bucket of an excavator. Background In northern areas, the problem that the material is frozen and stuck easily occurs in the running process of the excavator in winter, the water-containing material is slowly frozen and stuck on the inner wall of the bucket layer by layer after contacting the inner wall of the bucket at low temperature, the water-containing material is stuck more and more thick, the inner space of the bucket is compressed, the actual volume of the bucket is reduced, the quantity of the material entering the bucket is reduced, and finally the production capacity of the excavator is reduced, so that the material frozen and stuck by the bucket has to be stopped and cleaned. The materials in the shovel are cleaned by manual cleaning, and workers smash and buckle frozen and stuck materials by hammers, chisels, crowbars and the like. The temperature in winter in cold areas is extremely low, the lowest temperature in winter in partial areas even reaches-40 ℃, the freezing and sticking of materials in the shovel bucket are very firm, the breaking and freezing of the materials are very laborious, and a crowbar is difficult to insert into the lower part of the frozen and stuck materials to pry up the frozen and stuck materials, so that workers are extremely difficult to clean the frozen and stuck materials in the shovel bucket by adopting simple tools such as the hammer, the chisel, the crowbar and the like, the time is long, the effective working time of the excavator is seriously shortened, the yield of a production system is reduced in winter, and the supply protection production of coal in winter is seriously influenced. Meanwhile, the working condition of the worker for buckling and freezing and adhering the material is very bad, the labor intensity is high, the working difficulty is increased in the cold and bad environment in winter, the working efficiency is reduced, and the safety risk that the worker is injured by smash exists.
