Preferably, described two driving chain sprockets all are connected on the output shaft of gearbox in the traction electric machine, and traction electric machine is connected with gearbox.
The utility model has changed by original driving chain sprocket and has been installed in coal-winning machine inside, coal-winning machine is realized moving up and down of coal-winning machine by the traction electric machine drive driving chain sprocket of fuselage interior on conduction chain, change its driving chain sprocket into be installed in coal-face two ends, utilize two driving chain sprockets to make the power traction chain and realize moving up and down of coal-winning machine.This kind mode of traction practice is simple, the traction electric machine at two ends can increase and reduce tractive force according to the weight of coal-winning machine, owing to not limited by the coal-face spatial altitude, therefore, traction electric machine also can not be subjected to the restriction of locus, drive system is positioned at the two ends outlet of work plane, makes things convenient for plant maintenance and replacing.
The beneficial effect of a kind of external traction apparatus of thin coal seam shearer of the utility model is, change the driving chain sprocket of coal-winning machine into be installed in coal-face two ends, utilize traction electric machine to drive driving chain sprocket and do moving up and down of power traction chain realization coal-winning machine, the tractive force of this kind mode is very big, drive system is positioned at the two ends outlet of work plane, maintains easily and changes.
Description of drawings Fig. 1 is the low seam mining machinery structural representation of prior art;
Fig. 2 is a structural representation of the present utility model.
The specific embodiment is further described the utility model below in conjunction with accompanying drawing, but therefore the utility model is not limited among the described scope of embodiments.
Referring to Fig. 2, a kind of external traction apparatus of thin coal seam shearer, comprise fuselage 1, piston shoes 2, Scraper Conveyer Middle Trough 3, traction electric machine 4, driving chain sprocket 5, conduction chain 7, attachment pegs 8, swivel pin 9, rocking arm 10, cutting motor 11, helix drum 12, the two ends, the left and right sides of described fuselage 1 are connected with rocking arm 10 respectively by attachment pegs 8 and swivel pin 9, and rocking arm 10 is connected with helix drum 12 respectively; The bottom of fuselage 1 is provided with piston shoes 2, piston shoes 2 place the top of Scraper Conveyer Middle Trough 3, it is characterized in that: the upper and lower exit at work plane is equipped with driving chain sprocket 5,7 whiles of conduction chain are connected with the driving chain sprocket 5 in the upper and lower exit of work plane, at least one driving chain sprocket 5 is connected with the output shaft 411 of gearbox 41 in the traction electric machine 4, and traction electric machine 4 is connected with gearbox 41.
