| The knowing of the shearing properties of buxus stalk have important role in the design and fabricate of buxus pruning machine. A series of laboratory tests were conducted to measure the shear force, shear consumption energy and shear strength of stem internodes of buxus stalk under impact cutting at four loading rates: 1, 2, 3 and 4 m/s, three internodes: fifth, tenth and fifteenth and moisture content level 72% wet base. In this test, the stalk specimens were served in impact cutting process by using a special cutting test apparatus that was designed, fabricated, and calibrated. To define the impact cutting force of buxus stem, the apparatus was attached with beam type load cell and shear blade. The variance analysis of the data results showed that the... |
