DEVICE FOR CUTTING VEGETABLE WITH HEAD

摘要

PROBLEM TO BE SOLVED: To provide a head-having vegetable cutting device which is suitably adopted into a harvester for harvesting head-having vegetables such as cabbages and which can precisely cut off the rhizomes of the vegetables from the head portions. SOLUTION: A nipping and carrying portion 2 is synchronously driven with a cutting blade-driving portion 6. It is detected that the rhizome of a vegetable having a head is placed at a prescribed position in the nipping and carrying portion 2. and a cutting blade 5 is then reciprocatively moved from the side of the nipping and carrying portion 2 to a position for carrying the rhizome. The cutting blade 5 has a circular or curved cross-sectional shape expanded on the side of the head 1a. A contact terminal 7 coming into contact with the carried rhizome is disposed between one pair of right and left augers in the nipping and carrying portion 2. The cutting blade-driving portion 6 is driven in connection with the contact terminal to once reciprocate the cutting blade from a cutting-waiting position to a cutting position. In interlock with the operation of the cutting blade-driving portion 6 the connection of the contact terminal to the cutting blade-driving portion 6 is cancelled. Energizing mechanisms 13, 14 for returning the contact terminal to the contact-waiting position at a stage when the rhizome is carried to a position being not in contact with the contact terminal are arranged.
