| 摘要 |
The invention relates to a method and device for controlling the advance and cutting roller height of a shearer loader according to the load measured directly on the roller carrier arm. The invention is characterized in that the load on the carrier arm (2) is directly measured by means of a strain gauge strip (1). The measuring values are compared with a set threshold value . If the threshold value is exceeded, the speed of the winch and therefore the speed of advance is reduced using the advance control. If the cutting roller height control is used, the cutting roller (6) is lowered or raised. If the load of the roller carrier arm is reduced, the above-mentioned measures are inverted. The invention relates to control of the advance and cutting roller height of shearer loaders which are used in underground mining for extracting minerals found in stratum-type deposits.
