Mechanical tree shaker for fruit harvesting

摘要

The low power agricultural mechanical tree shaker for fruit harvesting using phase-controlled linear impact vibrations includes an adjustable springs set (FIG. 3) (8) that connects the vibrator set (FIG. 1) (1) to the clamp/trunk or limb set (FIG. 1) (4) (FIG. 5) through the guiding system (FIG. 3) (9, 10, 18, 19) and allows to set the spring tension for resonance vibration after attaching the shaker to a particular tree. Consequently, the vibration of the shaker set will have an adjustable phase angle between the shaker set and the clamp/trunk or limb set, between 0 DEG and 360 DEG . The clamp has the form of a fork (FIG. 5) and includes a set of vulcanized asymmetric grips (FIGS. 3 and 5) (15), a vulcanized chains set (FIG. 5 (17), for the attachment of the clamp to the tree.
