Abstract

The invention relates to equipment for mechanizing coal mining. Dahl - ensuring uniformity of the engine of the combine and improving its reliability. The combine gearing mechanism includes a housing I connected with the conveyor 2. Inside the housing 1 there are power cylinders 5, which are hingedly connected to it from one side. On the other hand, they are connected to the crankshaft (KB) 6. By means of a mechanical transmission .7 KB 6 is connected to the camshaft 8. The latter is connected by means of levers 9 to the block of control valves 10. The reciprocating movement of the power cylinders 5 by KB 6 converted into rotational motion. As a result, the drive sprocket associated with the KB 6 moves along a rail mounted on the conveyor 2, which also drives the combine. 3 il. cC (L concocted with 1 Fig.

The invention relates to mining and is intended for mining combines.

The purpose of the invention is to ensure uniform movement of the combine and increase the reliability of its work.

Figure 1 shows the movement mechanism, front view; figure 2 - section - cut A-A in fig.L; Fig. 3 shows the switching circuit of power cylinders and distribution valves.

The movement mechanism of the mining combine comprises a housing 1 associated with the bottomhole conveyor 2, a drive sprocket 3, which is in engagement with the rail 4. Inside the housing 1 there are power cylinders 5, which are connected with the housing 1 on one side. on the other hand, it is movably connected to the crankshaft 6, on which the drive sprocket 3 is fixed. The crankshaft 6 is mediated by%: g 2: “oG8GG orgp :: re” - “6th”, including “ch.”. 9, it is connected with a block of cylinders, a drive sprocket and re-distributor valves. ten.

rotates into rotational motion. As a result, the sprocket 3, which is connected to the crankshaft 6, begins to roll on the rail 4, which sets in motion the entire combine.

At the time of the passage of the crankshaft so-called; dead points automatically by means of a camshaft 8, the switching valves P and 12 switch over, with the result that the rod and piston cavities of the power cylinders 5 communicate alternately with the pressure 14 and then the drain 15 lines. The change in the direction of movement of the combine is carried out by changing the direction of movement of the working fluid using the valves 13.
