The specific embodiment:
Below in conjunction with accompanying drawing, the present invention is done further and explained.
As shown in Figures 1 to 4, a kind of brill formula coal-winning machine front end transmission case of the present invention comprises front moving box body 2, the rear end of front moving box body 2 is provided with left-handed drilling rod output 8 and dextrorotation drilling rod output 7, and the front end of front moving box body 2 is provided with left-handed drill bit input 9, dextrorotation drill bit input 11 and middle drill bit input 10.Left-handed drilling rod output 8 connects left-handed drill bit input 9 by long-and-short-addendum teeth axle 1, and dextrorotation drilling rod output 7 connects dextrorotation drill bit input 11 by long-and-short-addendum teeth axle 2 19, and middle drill bit input 10 connects long-and-short-addendum teeth axle 3 18.Long-and-short-addendum teeth axle 1 is in transmission connection with long-and-short-addendum teeth axle 3 18 by high displacement idler shaft 1 and high displacement idler shaft 2 17 successively, and long-and-short-addendum teeth axle 2 19 is in transmission connection with long-and-short-addendum teeth axle 3 18 by high displacement idler shaft 3 20, high displacement idler shaft 4 21 and high displacement idler shaft 5 22 successively.During coal-winning machine work, left-handed drilling rod and left-handed drilling rod are given left-handed drilling rod output 8 and dextrorotation drilling rod output 7 by transmission of power respectively; Left-handed drilling rod output 8 passes to left-handed drill bit input 9 by power by long-and-short-addendum teeth axle 1, and long-and-short-addendum teeth axle 1 power of having more than needed passes to long-and-short-addendum teeth axle 3 18 by high displacement idler shaft 1 and high displacement idler shaft 2 17 successively; Dextrorotation drilling rod output 7 passes to dextrorotation drill bit input 11 by power by long-and-short-addendum teeth axle 2 19, and long-and-short-addendum teeth axle 2 19 power of having more than needed passes to long-and-short-addendum teeth axle 3 18 by high displacement idler shaft 3 20, high displacement idler shaft 4 21 and high displacement idler shaft 5 22 successively; Long-and-short-addendum teeth axle 3 18 is given middle drill bit input 10 by transmission of power.Because left-handed drill bit input 9, dextrorotation drill bit input 11 and middle drill bit input 10 are three-shaft linkage formula arrangement, cutting power and the rotating speed of left-handed drill bit input 9 and dextrorotation drill bit input 11 are consistent constantly, and in the time of can effectively preventing drilling operation, the problem of front end transmission case side sideslip occurs.
The front box body top of moving is provided with upper left coal column support 1 and upper right coal column support 12, and the axis of upper left coal column support 1 and the axis of left-handed drilling rod output 9 are crossing, and the axis of upper right coal column support 12 and the axis of dextrorotation drilling rod output 11 are crossing.Before the bottom of moving box body 2 be provided with that lower-left coal column supports 5, bottom right coal column support 13 and in lower coal column support 14, lower-left coal column support 5 axis and bottom right coal column support 13 axis respectively with the stagger distance of a drilling rod radius of gyration of the axis of left-handed drilling rod output 8 and the axis of dextrorotation drilling rod output 7, in lower coal column to support 14 axis crossing with the axis of middle drill bit input 10.The bottom of left-handed drilling rod output 8 and dextrorotation drilling rod output 7 is main defeated coal channel, staggered after certain distance with the axis of left-handed drilling rod output 8 and the axis of dextrorotation drilling rod output 7 respectively in the axis of the axis of lower-left coal column support 5 and bottom right coal column support 13, both can provide enough support forces, also make defeated coal channel clear and coherent, improved the defeated coal efficiency of drilling rod simultaneously.
Lower-left coal column support 5 with in lower coal column support 14 between and in lower coal column support 14 and bottom right coal column support 13 between be provided with coal scraper plate 3, this coal scraper plate 3 is self-locking structure.The upper end of coal scraper plate 3 is connected with the underneath hinges of front moving box body 2, the lower end of coal scraper plate 3 can be rotated around the upper end of coal scraper plate 3, and between the rear end of the lower end of coal scraper plate 3 and front moving box body 2, be provided with back-moving spring 4, at coal scraper plate 3, near a side of front moving box body 2 front ends, be provided with coal scraper plate limited block 6, coal scraper plate limited block 6 is fixedly connected with the bottom of front moving box body 2.When coal-winning machine creeps into, coal scraper plate 3 upwards turns to minimum angles under back-moving spring 4 pins down, and it does not hinder the output of normally creeping into coal cinder; When coal-winning machine retreats defeated coal, coal scraper plate 3 self-lockings are opened, coal scraper plate 3 is pivotally lowered into maximum angle, and paste dead with coal scraper plate limited block 6, coal scraper plate limited block 6 is given the enough support forces of coal scraper plate 3, and the coal cinder dropping outside defeated coal channel is scraped in defeated coal channel and exported by drilling rod conveying blade.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
