GEAR PRESS Russian patent published in 2012 - IPC A01F15/00 B30B11/28 

FIELD: agriculture.

SUBSTANCE: invention relates to the agricultural machine industry and can be used for pelleting and briquetting of forages. Gear press includes tooth-wheels with pressing channels in the hollows. Each tooth-wheel contains an insertion mounted with an ability of axial movement and connected with the tooth-wheel by screw connections. The outer diameter of the insertion is 5…10% less than the diameter of the pitch circle of the tooth-wheel. On the surface of the insertion directed to the tooth-wheel the protrusions are made. The number and width of the protrusions is equal to the number and width of the channels in the tooth-wheel. The height of the protrusions of the insertion is 0.2…0.4 of the depth of the tooth-wheel channels. In the peripheral area of each protrusion of the insertion on the surface facing the tooth-wheel, a bevel is made. The angle between the surface of the bevel and the plane perpendicular to the axis of the tooth-wheel does not exceed 10°.

EFFECT: by choosing a rational section of channels of pressing by axial movement of the insertion, the efficiency of pressing of crushed materials is increased.
