TRACTORS FOR AGRICULTURAL HARVESTERS VIBRATING

摘要

The present invention relates to a farm product harvester for tractors which is placed at the back of a tractor to help a tractor to collect tubers such as sweet potatoes and potatoes and, more particularly, to a farm product harvester for tractors for removing foreign materials from farm products by vibrating a sieve guiding farm products. The vibrating farm product harvester for tractors placed at the back of a tractor comprises: a frame for fixation having a plurality of connection links for itself to be attached at the back side of a tractor; a ��shaped main frame comprising fixations for installation installed at two end parts of the frame for fixation; a rotation cam type vibrator for generating vibration through rotational power transmitted from a tractor and which includes PTO connection rotational axis installed at the center of the frame for fixation; a vibration connection rode for transmitting vibration generated by the vibrator; a vibration frame of which the upper part is connected to the vibration connection rod and of which the middle part is combined to the fixations for installation to rotate around a hinge axis; a blade for fixation installed at the lower part of the fixation for installation; a blade for work comprising vibrational blades installed on the vibrating frame; a first vibrator which vibration of the vibration frame is transmitted to and which is installed at the lower part of the vibrating frame; and a vibrator body including a second vibrator to transmit the vibration of the vibrating frame and which is extended to the first vibrator to improve the fertilizer efficiency.
