SYSTEM FOR SHARPENING OF BLADES TO BE MOUNTED AT AGRICULTURAL IMPLEMENTS Russian patent published in 2015 - IPC A01B5/00 A01B7/00 A01B15/16 

FIELD: process engineering.

SUBSTANCE: in compliance with the first version, claimed system comprises sharpening tool, rail and locating tool. Said sharpening device comprises the grindstone to be engaged with the implement round blade. Said rail supports said sharpening device and to facilitate the latter along said rail. Said locating part is engaged with the rail and will be engaged with the implement structural parts and those of said sharpening device while the rail and sharpening device are to be secured at the implement without fasteners. In compliance with the second version, claimed system comprises the sharpening device, first and second motors, drive unit, locating part and controller. The sharpening device comprises the same parts described in said first version as well as grinding wheel to sharpen the blade cutting edge. The first motor drives the grinding wheel to spinning. Drive unit is meant for revolving the blade relative to aforesaid sharpening device. The drive unit comprises the wheel to engage with the blade. The second motor serves to drive the wheel. The locating part can secure to the drive unit attach the drive unit to the implement structural element and can be detached therefrom. The controller controls the first and second motors. In compliance with the third version, the system comprises the sharpening device, rail, locating device and drive unit. Said sharpening device includes the grindstone. Grindstone comprises grinding wheel to sharpen the blade cutting edge and first motor to drive the grinding wheel. The rail carries the sharpening device to facilitate its displacement along the rail. The locating part is engaged with the rail to engage with the implement structural element and supports both the rail and sharpening device. Said drive unit spins the blade relative to grindstone and comprises the wheel to be engaged with the blade. The second motor serves to drive the wheel. The sharpening device comprises the carriage to engage with the rail and the grindstone support. Grindstone support can spin relative to said carriage between the position of engagement with the blade and that whereat it is disengaged therefrom.

EFFECT: higher efficiency of blades owing to sharpening without removal from the implement.
