Through the left automatic sharpening mechanism and the right automatic sharpening mechanism which are arranged in pair, the device can sharpen two adjacent moving blades simultaneously, and the sharpening efficiency is improved.
The sharpening stone is fixedly connected with the driving end of the electro-hydraulic push rod through the fixing sleeve, the fixing sleeve is provided with a connecting cavity, and the shape of the connecting cavity corresponds to that of the sharpening stone.
Through setting up fixed sleeve, the connection of the whetstone of being convenient for is fixed.
The side wall of the connecting cavity is provided with a fixed adjusting bolt hole and an adjusting fixing bolt.
Through setting up fixed regulation keyhole, regulation gim peg, be convenient for connect fixedly to the whetstone, and can carry out the adjustment of protrusion to the whetstone after wearing and tearing, the make full use of material of being convenient for.
