Abstract:
A tree shaking device for collecting fruits from trees, comprising a housing (2) containing an eccentric kinematic mechanism (3) and a reciprocating rod (9) partially housed within said housing (2) and equipped at its free end with a hook (11) . To the housing (21) of a light alloy there is fastened a steel bush (14), preferably embedded in the light alloy casting of the housing (2), that supports the kinematics mechanism (3) comprising an eccentric member (3) and two bearings (15, 16).
Abstract:
A tree shaking device for collecting fruits from trees, comprising a housing (2) containing an eccentric kinematic mechanism (3); a reciprocating rod (4) partially housed within said housing (2) and equipped at the free end with a hook (11); a front tubular handgrip (13) which partially embraces said rod (4) and a rear handgrip (15) on which the motor controls are mounted. The front handgrip (13) is freely slidable over a tubular protection (10) fastened to the housing, thus reducing the transmission of reaction forces to the user.
Abstract:
A tree shaking device for harvesting fruit from trees, comprising a housing (2) containing a reduction gear driven by a motor (4) for imparting a reciprocating motion to a rod (9) provided with a hook (11) at one end for engaging the tree branches, a rear handgrip (15) connected to said housing (2) and carrying the device controls, and a front tubular handgrip (22) having a polygonal inner cross section and axially slidable along a sleeve (21) having a polygonal outer cross section and being integral to said rod (9), whereby said hook (11) can rotate while the device is operating and no axial vibrations are transmitted to the hand of the operator.

Abstract:
Portable handheld power tool for use in farming and gardening works, in particular a shaking device for collecting fruits, comprising a motor (15), a motor housing (12) and a rod (14) carrying an end tool (11) driven by said motor (15). The motor can be mechanically disengaged from the tool through a centrifugal clutch (18) comprising a clutch body (21) fastened to said motor, in which at least one friction shoe (22) is rotatably mounted for engaging a clutch drum fastened to a rod driving mechanism. In order to reduce wear-and-tear, each friction shoe (22) is mounted on the clutch body (21) through a ball bearing (27) housed into a seat (29) formed in said body. The invention further relates to an improved centrifugal clutch for a portable handheld tool to be used in farming and gardening works.
Abstract:
The present invention relates to a tracked hand-truck (1) driven by an electric motor (9) and provided with a mechanical gear system (19) for transmitting the motion from the output shaft of said electric motor (9) to the track assemblies (7a,7b) of said hand-truck (1). Thanks to the provision of said mechanical gear system (19) it is possible to obtain a steering system and a standstill system that are simple, cheap and reliable. According to the invention, thanks to the combination of an electric motor (9) and a mechanical gear system (19) the speed and the energy consumption of the hand-truck (1) can be modified according to the needs of the user both by acting on the motor (9) through a first electric adjustment system and by acting on the mechanical gear system (19) through a second mechanical adjustment system, separated and independent from said first electric adjustment system.
