CHEEK CRUSHER SUPPORT FRAME Russian patent published in 2017 - IPC B02C1/02 

FIELD: mining.

SUBSTANCE: crusher (100) comprises a movable cheek (105) and basically immovable cheek (104) with a crushing zone (103). The drive mechanism is connected to the movable cheek for its fluctuations against the immovable cheek to crush material. The connection joint with the mechanical drive is connected to the movable cheek to control the distance of separating the movable and immovable cheeks. The support frame (118) supports the movable cheek through the connection joint. The support frame includes a wall (125) of power transmission. The wall generally extends in a plane transverse or perpendicular to the longitudinal axis (128) of the connection joint. The first (300) and the second (400) side of the wall are located to face the movable cheek and backwards from the movable cheek respectively. The opening (202) enables piston to extend (117) from the first side of the wall. The piston is connected to a mechanical drive (116) located on the second side. The first (126) and the second (127) areas of the reinforcing ends continue along the first and second longitudinal ends of the wall. Each area comprises the first (302, 305) and the second (126, 127) flanges. The first flange comes forward from the first side of the wall towards the movable cheek. The second flange extends from the second side of the wall away from the movable cheek.

EFFECT: strength and weight optimisation is provided due to the profile of the wall transmission forces of the rear end of the frame.
