Abstract:
The present invention relates to a balancing group (17; 17'; 17") for motorized tree-shaking devices having a vibrating shaft (11) equipped with a hook (13); to its balancing method; and to a device that incorporates said group having a mass (21; 21'; 21") oscillating along an arched trajectory defined by a guiding element (25; 25', 25") and operated by a control unit (7b, 15) associated to the movement of said shaft.
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:
The present invention relates to a portable shaker apparatus for harvesting olives. The shaker apparatus according to the invention comprises one or more prong holder arms (5) rotatably mounted to the head (2) of the apparatus by means of respective pivot pins (7), and is characterized in that each prong holder arm is mounted to the corresponding pivot pin with the interposition of at least two rolling bearings (15a, 15b) preferably arranged at a mutual distance. By providing at least two rolling bearings (15a, 15b) arranged at a distance from each other, tilting torques to which the prong holder arms (5) are subjected during use of the apparatus according to the invention are effectively managed. As a result, the deformation and wear effect of the rolling tracks of the bearings (15a, 15b) is reduced, with consequent increase in the reliability of the shaker apparatus, because of wear reduction, and a considerable decrease in the vibrations transmitted to the operator.
Abstract:
Reversibly installable modular fitness area comprising a plurality of modules (100), variously assemblage due to common stable and reversible connection system, which when joined together give rise to stage-like structures, each of which comprising one or more equipment pieces for carrying out fitness exercises. Especially opposite support modules (100', 100") have slingshot arm shape, and each of the stages is equipped with a display illustrating how to perform the exercise.
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.
Abstract:
A portable power tool (1) for use in farming and gardening works, comprising a motor (2), a tubular member (6) at least partially housing a transmission member connecting said motor (2) to an end tool (25) driven by said motor, a handlebar (3) with at least one handgrip (4,5) being fitted to said tubular member (6) through a fastening device (9) comprising elastic means (14, 15). The fastening device (9) comprises a case (16) fitted around said tubular element (6) and a clamp (10, 11)to which said handlebar (3) is secured, that are connected to each other by a connecting element (18) surrounded by a first pair (14, 14) of elastomeric elements and by a second pair (15, 15) of elastomeric elements surrounding said first pair of elements and with a hardness different from that of the first pair.
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 (Figure 5).
