Abstract

This invention discloses a prickly pear harvesting device. The device is moved to the prickly pear tree to be harvested, and a collecting umbrella mechanism surrounds the tree trunk. Hydraulic cylinder I drives a gantry frame to rotate, and hydraulic cylinder II drives sliding plates to slide, positioning the two sliding plates on opposite sides of the prickly pear canopy. Then, an eccentric drive mechanism drives a V-shaped frame to continuously open and close in a V-shape via a transmission rod. Driven by the V-shaped frame, the harvesting plates repeatedly encircle the prickly pear canopy, and the harvesting rod repeatedly inserts into the canopy, causing the prickly pears to fall into the collecting umbrella mechanism, thus achieving the purpose of harvesting the prickly pears. This invention confines the prickly pear canopy to a localized area through repeated shaking, pulling, and striking, effectively increasing the fruit drop rate to as high as 81.7%. The fruit and branch damage rates during harvesting using this invention are minimal. With a fruit drop rate of 81.7%, this is sufficient to meet the needs of large-scale industrial harvesting of prickly pears.
