The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further.
To shown in Figure 4, this low seam mining machinery multifunctional rolling cartridge comprises driving wheel 20, transmission case 30, master rotor 40, spillplate 50 and auxiliary cylinder 60 like Fig. 1; Also comprise rotary positioning mechanism 10, driving wheel 20 inner bulge shoulders lean on old man's side through being bolted to master rotor 40 cylindrical shells, and rotary positioning mechanism 10 connects with rocking arm 70 through bolt; The wheel hub 62 of auxiliary cylinder 60 leans on bolt to connect with the output shaft 37 of transmission case 30, and rotary positioning mechanism 10 comprises handle 11, fixed cover 12, sliding bearing 13, splined shaft 14 and ring gear 15, and handle 11 has interior external splines; The interior external splines of handle 11 meshes with the external splines of splined shaft 14 and the internal spline of fixed cover 12 respectively; There is external gear splined shaft 14 lower ends, external gear and ring gear 15 engagements, and ring gear 15 connects through bolt and transmission case 30; Fixed cover 12 right sides connect through bolt and rocking arm 70; Transmission case 30 comprises that housing 31, three 32,33,34, two idle pulleys 35,36 of change-speed gearing, output shaft 37 and 32,33,34 and two idle pulleys 35,36 of 38, three change-speed gearings of axle sleeve mesh successively, all are arranged in the housing 31; Output shaft 37 connects with idle pulley 36, and the outside of output shaft 37 is provided with axle sleeve 38.
The present invention is divided into left and right sides two parts; Be symmetrical structure; Be installed in respectively on the cutting units tie-plate of the left and right sides; External splines length on the splined shaft 14 should guarantee rotary positioning mechanism 10 can be effectively in the scope of endwisely slipping with the engagement of driving wheel 20 internal splines with fully separate, when the internal spline of rotary positioning mechanism 10 and fixed cover 12 separates, can turning handle 11; External splines through splined shaft 14 is given the external gear of splined shaft 14 terminations and the gear pair that ring gear 15 is formed with transmission of power; Drive whole transmission case 30 and auxiliary cylinder 60 and do upset or small rotatablely moving, when rotating to desired location, rotary positioning mechanism 10 external splines are pushed in the fixed cover 12 around master rotor 40 axis.Under the normally coal mining situation of coal-winning machine, as shown in Figure 5, auxiliary cylinder 60 places master rotor 40 back, and master rotor 40 is responsible for coal cutting, auxiliary cylinder 60 auxiliary coalingging; When coal-winning machine moves to the end,, make auxiliary cylinder 60 and transmission case 30 turn to master rotor 40 opposite sides according to above-mentioned steps operation rotary positioning mechanism 10; And fully drop to base plate; As shown in Figure 6, at this moment, the pick 61 of auxiliary cylinder 60 is responsible for cutting off not " the triangle coal " of easy to clean.Transmission case 30 is at change-speed gearing 34 places, and kinetic current is divided into two-way, through change-speed gearing 35 and change-speed gearing 36; Pass to two auxiliary cylinders 60 by output shaft 37, separately two auxiliary cylinders 60 have the identical characteristics of motion in two multifunctional rolling cartridges of front and back, through gearbox; Auxiliary cylinder 60 has the rotating speed close with master rotor 40, opposite rotation direction, and auxiliary cylinder 60 is opposite with master rotor 40 helical blade rotation directions; The direction of motion is opposite, and the two combines to have improved greatly to coaling and defeated coal efficient.
In order to improve effect of loading coal; Spillplate 50 is arranged on 60 of two auxiliary cylinders, and transmission case 30 connects and extend near auxiliary cylinder 60 terminations, stops the coal outflow of 60 of two auxiliary cylinders; Two auxiliary cylinders 60 and a spillplate 50; Master rotor 40 forms certain cornerite relatively, has played the retaining coal and has strengthened the effect of coalingging, and three's existence obviously improves the effect of loading coal of cylinder.
