As shown in the accompanying drawings, the working principle and operating conditions of the large-inclination vertical drum shearer of the present invention are as follows:

1. Position placement and adjustment of the large-inclination vertical drum shearer of the present invention: first, a certain pile is artificially driven at the top of the coal seam mining face, that is, at the auxiliary roadway, and a gap is dug at the main roadway of the coal seam mining face As machine position, the steel rope 38 on the shearer reel 5 at the gap is pulled out and fixed on the fixed pile, and at the same time, the traction rope of the auxiliary traction hoist is fixed on the tail hook 32 at the rear of the body 2, so that The shearer is tilted as a whole, so that the tail portion of the body 2 and the extension arm 4 faces upwards and the front portion faces downwards, and is placed right along the coal seam mining face. In the dug gap, loosen the fixed connection bolts between the machine body 2, the bracket seat 34 and the skid 35, turn on the power supply, and pull the shearer to move upward slowly by the auxiliary traction hoist until the machine body 2 is completely moved to the coal seam excavation. On the working surface, the drum 5 just contacts with the vertical surface of the coal seam mining working surface.

Two, the excavation process of the large-inclination vertical drum shearer of the present invention: (1), after removing the support seat 34 and the skid 35, lay and install other auxiliary facilities, and then coal mining can be carried out; (2), by The explosion-proof motor directly drives the main transmission wheel 9 on the motor main shaft 8 to mesh with a pair of auxiliary transmission wheels 10 to make the power transmission chain 3 run, and drives the longitudinal front and rear transmission shafts 11 and 12 to output power synchronously; (3), the front transmission shaft 11 The end bevel gear 13 drives a bevel gear shaft 14 and the spur gear 15 on the shaft to rotate, and the spur gear 15 drives the third-stage transmission gear 16 and the transmission gear shafts 17 of all levels to rotate, thereby driving the final transmission gear shaft 18 and its half The drum 5 on the flexible coupling 19 rotates, and the pick 39 on the drum 5 rotates synchronously with the spiral chute 40 to complete coal mining and coal output. Laying in the enamel chute of the mining roadway, due to the large inclination angle of the mining roadway, the speed of coal passing through the enamel chute will be accelerated, directly slipped into the main roadway below the mining roadway, and then transported to the ground by transportation equipment; (4), The end worm 20 of the rear transmission shaft 12 drives the worm gear shaft 21 and the reel 6 on the shaft to rotate, and the steel rope 38 on the reel 6 forms a steel rope traction power transmission chain under the action of a fixed fulcrum above the coal seam mining working face to realize Synchronized with the rotation of the drum 5, thereby tightening the steel rope 38, so that the shearer slowly moves upwards and climbs along the coal seam mining face; (5), the direction of the shearer during the mining movement and the protection of the body 2 are set by The four anti-friction safety wheels 33 at the four corners of the body 2 are controlled. When the body 2 encounters the bending of the coal seam mining face during the movement, because the two outer wheelbases of the four anti-friction safety wheels 33 on the body 2 are larger than the body 2 and the drum 5, so the four anti-friction safety wheels 33 are first in contact with the roadway wall of the coal seam mining face, and with the movement of the shearer, the anti-friction safety wheels 33 are purely rolled, guiding the shearer to cling to The movement of the roadway wall automatically controls the forward movement, and also protects the body 2 and the drum 5 from collision until all the coal seams are excavated here.

Three. The transition of the large-inclination vertical drum shearer of the present invention: (1), after the coal seam excavation is completed, when it is necessary to transition, the support seat 34 and the skid 35 are placed below the body 2, and the opening above the excavation roadway is opened. Auxiliary traction hoist to make the shearer move downwards slowly until the shearer is fully moved to the bracket seat 34 and the skid 35, and is fixed by inserting bolts into the bracket connection hole 41; Sliding function makes the shearer on the skid 35 slowly slide down to the main roadway, so far the coal seam mining process of the large dip angle roadway is over.
