Abstract

The invention discloses a damping mechanism of a coal mining machine. The coal mining machine 6 comprises a protective plate (6.1) at the top and a traveling base (6.3) at the bottom, a machine body (6.2) is mounted on the base (6.3), the protective plate (6.1) is supported by a supporting device (6.4) located on the base (6.3), the damping mechanism (11) is arranged at the bottom of the base (6.3), a supporting plate (11.9) is horizontally arranged in a casing (11.1) of the damping mechanism (11), two ends of the supporting plate (11.9) are glidingly arranged in the casing (11.1) through a sliding mechanism, the sliding mechanism comprises a sliding sleeve (11.4) arranged at one end of the supporting plate (11.9), a groove (11.5) is formed in the inner side wall of the casing (11.1), a slid rail (11.3) is vertically arranged in the groove (11.5), and the sliding sleeve (11.4) glidingly sleeves the slide rail (11.3). The damping mechanism has a good damping effect.

Description

technical field [0001] The invention belongs to the field of coal, in particular to a shock absorbing mechanism of a coal shearer. Background technique [0002] As an important part of the complete set of equipment in the fully mechanized mining face, the shearer has an important impact on the production of the mine and whether it can achieve high yield and high efficiency. It is also an important link to ensure the safe, reliable and economical operation of the fully mechanized mining face equipment. The shearer in the prior art generally includes a body and a cutting arm, and the drum is installed at the front end of the cutting arm. When the shearer cuts coal underground, it will generate a lot of vibration. The vibration force is mainly driven by the shearer drum. It is transmitted to the cutting arm, and the cutting arm is hinged with the fuselage to transmit the vibration to the whole machine. If the shearer vibrates too much when working underground, it will affect t...
