WORKING EQUIPMENT OF SHAFT LOADING MACHINE WITH CONTROLLED BUCKET Russian patent published in 2009 - IPC E21D1/04 E02F3/413 

FIELD: mining engineering.

SUBSTANCE: working equipment of the shaft loading machine with controlled bucket comprises a movable operating element consisting of pivotally connected hydraulic ram 6 and controlled bucket 7, mounting plate 1 equipped with a tillable spar 2 with a slewing gear 3, an arm 4 pivotally mounted on the tillable spar 2, a pivotally connected dipper arm 5 to the bottom end of which the movable operating element is mounted by its hydraulic ram 6, hydraulic racks 8 and 10 for arm and dipper arm rotation in a vertical plane. The operating element is equipped with two powered hydraulic racks 12, the housings of which are ball 13 jointed to the mounting racks 14 rigidly fixed on the hydraulic ram 6 housing and rods are connected to the yoke 15 of the controlled bucket by means of single pivot joints. The controlled bucket is connected to the hydraulic ram by means of a ball connector. The hydraulic rack 8 controlling boom swing in a vertical plane is connected with its top end to the mounting plate 1 by means of a ball connector 9 with a possibility of rotation in a horizontal plane together with the arm 4. The slewing gear of the tillable spar 2 is in the form of hydraulic rack jack 3.

EFFECT: improved mechanisation and increased capacity when charging mined rock into transport facilities when mounting vertical shafts.
