What should be paid attention to when the roadheader picks cut coal and rock?
The following items should be paid attention to when the roadheader picks cut coal and rock:
When the roadheader uses picks to cut rocks whose hardness is greater than the cutting capacity of the roadheader, stop using the roadheader and take other rock-breaking measures.
According to the degree of softness and hardness of the coal rock, the propulsion speed of the machine should be controlled to avoid overloading the cutting motor or crushing the scraper conveyor. The shovel should be lowered when cutting. If the amount of falling coal is too large and causes overload, the driver needs to stop immediately, and exit the roadheader for processing. It is strictly forbidden to start the machine by inching, so as not to burn the motor or damage the hydraulic motor.
The cutting head can only cut coal and rock under the condition of rotation. The cutting head is not allowed to start with load, the propulsion speed should not be too high, and overload operation is prohibited.
When the cutting head is in the low working position, it is forbidden to lift the blade. The distance between the cutting part and the shovel plate shall not be less than 300 mm, and it is strictly forbidden for the cutting head to collide with the shovel plate. When cutting the upper coal and rock, prevent the pick from touching the net and the beam.
Always pay attention to cleaning the bottom and cleaning the floating coal (rock) on both sides of the machine body. When sweeping the bottom, one knife should be pressed to avoid hard ridges at the bottom, so as to prevent the crawler from getting higher and higher when it moves forward.
