Description

Technical Field

[0001] The utility model relates to the technical field of filling mechanical equipment, in particular to an adjustable gangue throwing machine for tunnel filling. Background Art

[0002] With the continuous exploitation of coal resources, many artificial spaces have been formed underground, causing the surface to sink, and gangue has accumulated on the ground, forming gangue mountains. The large amount of gangue piled up has a serious impact on the normal production of the mining area and brought about a series of social and environmental problems.

[0003] When filling the goaf of coal mines with waste rock, waste rock throwing machines are generally used. Existing waste rock throwing machines have poor adjustability, so some people usually set an adjustment cylinder under the conveyor belt to achieve adjustment. For example, the Chinese utility model patent with announcement number CN211495658U specifically discloses a self-made remote control waste rock throwing belt device for mining.

[0004] However, when the above-mentioned gangue throwing machine is actually used, people will find that when adjusting the device, the frame is only pushed up by starting the oil cylinder to adjust the overall height. However, after the adjustment, the frame is not provided with a limiting structure, which leads to poor overall stability during operation and greatly increases the safety hazard. Utility Model Content
