Description

The invention relates to mining equipment intended for excavation of flat mineral deposits of materials with relative gas impermeability, mainly potash ores, with limited width of combine moves under the condition of stability.

The purpose of the invention is to increase the productivity of a mining combine by combining continuous shipment of ore with the operation of a combine.

FIG. 1 shows a combine, side view} in FIG. 2, view A of FIG. one; in fig. 3 is a section BB in FIG. 2

The harvester contains outer 1 and inner 2 crowing crowns which are connected to the corresponding drive 4 and 5 through the gearbox 3, and the gear case 3 is pivotally connected to the feed and displacement body 7 through the hydraulic cylinder 6 and connected to the delivery pipe 8, which the hinge 9 is connected to the chassis 7 and forms the bearing beam of the combine design. One end of the delivery pipe 8 is located in the central part of the outer 1 and inner 2 brown crowns and is rigidly connected with a hollow spherical guide light 1Q protruding beyond the dimensions of crowns 1 and 2, and the other end through a flange connection 11 is connected to the loading machine 12, The spherical flashlight 10 is pivotally connected to the hollow sealer 13. The combine also includes a loading device 14, a fencing shield 15, a discharging window 16, a reloading device 17, discs 18, detachable rims 19 and a compressed air source 20.

The combine works as follows.

Using the feed and displacement body 7 and lifting jacks 6, the hollow sealer 13 and the spherical guide light 10 are driven into the predetermined delivery well connecting the bottom of the combine to the transshipment point of the broken ore to district vehicles. When rotating the crowing crowns 1 and 2, berm milling cutters 19, cutting discs 18 and feeding the harvester to the face with the help of the feed and transfer organ 7, the ore is crushed. The loading device 14 captures the broken ore and through the discharge window 16 in the bend of the shield 15 fencing unloads it to the transfer device 17. The loading device 17 delivers the broken ore to the loading machine 12, in which the locking, dosing of the broken ore, mixing it with compressed air coming into the loading machine 12 from the source 20 of compressed air (for example, air blowers, a turbocharger, or from a mine network of compressed air). From the loading machine 12, the ore is repulsed by compressed air through the delivery pipe 8, the guide lantern 10, the sealer 13 enters the delivery well, which is delivered to the loading point to local or long-haul vehicles.

The hollow sealer 13 seals the delivery well from the side of the bottom of the harvester and simultaneously continues the delivery channel formed by the delivery tube and the guide light.
