Problems solved by technology

[0002] At present, the country is vigorously promoting the intelligent and unmanned coal mining face, but due to the cumbersome circuit system of the coal shearer and the straight-line coal cutting of the coal shearer, a single point of failure requires a complete shutdown of the working face for manual switching. This has greatly hindered the promotion of intelligent unmanned working faces; at the same time, the severe vibration of the shearer during operation caused a large area of ​​the coal wall in front, artificially damaging the load-bearing structure of the roof, which is not good for the roadway support

Abstract

The present invention provides a hook lift and a coal mining system. The hook hook includes a base, a turntable, a first rod body, a second rod body, a grab bucket, a connecting rod assembly and a driving assembly. The turntable is horizontally rotatable and arranged on the base. The rear end of the first rod body is vertically rotatably arranged on the turntable. The rear end of the second rod body is vertically rotatably connected to the front end of the first rod body. The grab bucket is vertically rotatably connected to the front end of the second rod body, and the grab bucket is provided with a breaking hammer. The connecting rod assembly is connected between the grab bucket and the front end of the second rod body. The driving assembly includes a first driving part, a second driving part and a third driving part. The first driving part is arranged between the turntable and the front side of the first rod body. The second driving part is arranged between the rear side of the first rod body and the rear end of the second rod body. The third driving part is arranged between the rear side of the second rod body and the connecting rod assembly.

Description

technical field [0001] The invention relates to the technical field of coal mining systems, in particular to a coal mining system applied to the N00 construction method. Background technique [0002] At present, the country is vigorously promoting the intelligent and unmanned coal mining face, but due to the cumbersome circuit system of the coal shearer and the straight-line coal cutting of the coal shearer, a single point of failure requires a complete shutdown of the working face for manual switching. This has greatly hindered the promotion of intelligent unmanned working faces; at the same time, the severe vibration of the shearer during operation caused a large area of ​​the coal wall in front, artificially damaging the load-bearing structure of the roof, which is not good for the roadway support . Contents of the invention [0003] A main purpose of the present invention is to overcome at least one defect of the above-mentioned prior art, and provide a coal mining sy...
