Abstract

FIELD OF THE INVENTION The invention relates to mining machinery, in particular to loading machines. The goal is to increase productivity and reliability. The working body has table 1, conveyor 2, hydraulic cylinders (HZ) 3 and 4, scoring legs 5 and 6. The synchronizing link 7 tons 8 and the arms of paws 5 and 6 form a hinged four-link. T he 8 has stops 9 and 10. A link 7 is pivotally connected by an axis 11 with a table 1. The arms of legs 5 and 6 have rollers 14 and 15 with the ability to move along axes 12 and 13 by an amount exceeding the thickness of the guides 16 and 17. 5 and 6 have reference areas. The rod cavity HZ 3 is connected to the piston cavity HZ 4 and vice versa. During operation, paw 5 extends HZ 3, roller 14 moves along guide 16. T ha 8 nepeMeiqaef to conveyor 2 paw 6. In the position of paw 5 Ki, stop 9 reaches the handle of paw 5, after which the four billet rotates as a rigid system around axis 11 K2, with the end of the paw 6 occupying the position of the Ka- At the same time, the paw 5 is inserted into the stack. Then, Hz 3 and 4 are reversed. Paw 6 moves to the KS position, and paw 5 to the Kz position, pushing the rock mass onto the conveyor 2. After that, the stop 10 limits the displacement of the four-link units, paw 6 moves to the point KB, and paw 5 - to point IGj. Then the cycle is repeated. When the HZ rod extends, the roller 15 of the foot 6 intersects the guide 17 on the side of its beveled edge. At the same time, the roller 15 rises by an amount equal to the height of the guide 17, after which it descends to the table 1. The roller 14 also works in a similar way. 1 cp f-ly, 3 ill.

Claims (2)

Claim 1. The working body of the loading machine, including paired raking legs located on the receiving table, a hinge .15 but connected to the synchronizing link and hydraulic cylinders, guides and rollers, characterized in that, in order to increase productivity and reliability, the raking legs are pivotally interconnected by additional traction, which at the ends has stops located with the possibility of interaction with the legs, while the raking legs, additional traction and the synchronizing link form a four-link. 2. The working body according to claim 1, with the fact that the guides are made of wedge-shaped plates, and the rollers are located on the legs with the possibility of interaction with the guides and movement in the axial direction.
