The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described.
As Fig. 1-shown in Figure 10, structural representation for a kind of separate assembling coalcutter of the present utility model, it comprises that mainly cutting units 1, motor section 2 and 3 three parts of tractive unit constitute, and wherein cutting units comprises coal cutting head and two part compositions of following coal cutting head again.Coal cutting head and following coal cutting head can independently respectively be connected and fixed to form with connecting bolt and motor section 2 and go up coalcutter and following coalcutter on this cutting units.This connecting bolt that is connected and fixed coal cutting portion 1 and motor section 2 is four.Motor places the machine middle part, the rear and front end projecting shaft is worked with the power shaft connection drive cutting units 1 and the coal cutting portion 3 of coal cutting variable transmission mechanism and traction variable transmission mechanism respectively, drives walking haulage gear and coal cutting operating mechanism simultaneously by traction variable transmission mechanism and coal cutting variable transmission mechanism.
The clutch system that the concrete structure of coal cutting operating mechanism is made up of by spline housing 10 motor spline 9 one ends and coal cutting portion spline passes to small bevel gear gear 8, slow down after vertical shaft 12 passes through pentacle weel 13 in the output of coal cutting variable transmission mechanism, driving chain cutter chain 4 rotates, clutch system is used for controlling the motion of cutter chain 4 and stopping, clutch system action bars 19 is to traverse motor section and tractive unit, concentrates on the operation of tractive unit end.Bottom jib 5 is to support by the bottom jib support 6 that is fixed on coal cutting portion, bolt governor motion 31 is fastened on the bottom jib, bottom jib support 6 is opened an elongated slot, rotating bolt governor motion 31 during tight chain, cutter chain 4 slides in bottom jib support 6 elongated slots, drive bottom jib 5 and move forward and backward, regulate the degree of tightness of bolt governor motion 31.But bottom jib 5 left rotation and right rotation become 90 °, fix by screw pin after bottom jib 5 anglecs of rotation.During the main frame tuning, bottom jib 5 must rotate at random.Be installed in as driven sprocket on the bottom jib 5 of coal cutting operating mechanism main body and cutter chain 4 formations, cutter chain 4 is provided with the sprocket 34 in cut coal seam, and pick is arranged by five lines.Said bottom jib 5 is again by upper cover plate 32, lower cover 33 be arranged on up and down that two hand hay cutters constitute to guarantee the panel 30 that constitutes die cavity between the cover plate, bottom jib 5 is installed in as coal cutting variable transmission mechanism casing and constitutes on the rolling disc 14 of a part, can be under the effect of directive wheel around coal cutting variable transmission mechanism output vertical shaft 12 left-right rotation 90 degree, promptly bottom jib can rotate in cut face 180 degree scopes.In order to regulate the tightness of chain, bottom jib 5 is provided with the bolt governor motion 31 of regulating the chain degree of tightness, and bolt governor motion 31 is arranged in the die cavity of bottom jib 5.Be fixed on the sprocket 34 in the cut coal seam on the chain, sprocket 34 directions are positioned at the chain traffic direction and spend to the cross section of hanging down positive and negative 60.The concrete set-up mode of sprocket 34 on chain as shown in figure 10.
