DEVICE FOR MONITORING AND AMORTIZING IMPACT FORCE OF FALLING COAL AND METHOD FOR BAND TRANSPORT SYSTEM IN COAL MINE Russian patent published in 2018 - IPC B65G43/00 B65G15/60 B65G39/14 B65G47/16 

FIELD: machine building.

SUBSTANCE: device comprises a group of (1) amortizing rolls, amortizing holder (2), damping springs (3), shock absorbing buffer (4), signal converting and transmitting device (5), and the main mounting plate (6), the band (1) of the amortizing reels for the tape is fixed to the amortizing holder (2), the upper ends and lower ends of the damping springs (3) and the shock absorber (4) are connected respectively to the amortizing holder (2) and to the main mounting plate (6), and the impact damper (4) is connected through the supply wires to a signal conversion and transmission device (5) which is fixed to the main mounting plate (6). Device is installed under the band in the area of the material falling.

EFFECT: impact damper (4) converts the impact force applied to the band in the material falling area into an electrical signal that is sent to the host computer (9), which determines whether a failure has occurred due to backfilling or not, thereby reducing the damage caused by the impact of falling coal on the band and performing protection of the coal backfilling by monitoring the process of falling coal.
