Hand-held powered soil cultivation device

摘要

A hand-held powered ground and soil cultivation device includes a handle, a first end of which includes a holding zone and/or a holding member for the user, and the opposite end of which includes a head to which a working tool is rotationally or pivotally attached. During operation of the device, the working tool performs a reciprocating oscillating movement along a portion of a rotation and about a predetermined central angular position under the effect of the movement transmitted by a drive unit including at least an electric actuator or a heat engine. The hand-held powered device is characterized in that the working tool is releasably attached to the head, the working tool being mounted on a drive shaft that performs a reciprocating oscillating rotational movement and forms a vertical or horizontal axis of oscillation for the tool. The central angular position of the working tool can be adjusted.

1. A handheld motor-driven soil and ground cultivation device (1), comprising:
a handle (2) that comprises,
at a first end (3), a gripping zone and/or at least one gripping element suitable for a user, and,at an opposite second end (4), a head (6) comprising a housing and a drive device (5) with a drive shaft (8), wherein a work tool (7) is rigidly attached, by a single fastening point, to the head (6) at the drive shaft (8) of the drive device (5) to rotate about an axis of rotation of the drive shaft (8) such that, when the device (1) is used, the work tool (7) is driven with a reciprocating oscillating rotational movement transmitted by the drive device (5) along a portion of rotation and around a specified middle angular position under the action of the reciprocating oscillating rotational movement, wherein the work tool (7) is connected removably to the drive shaft (8) of the drive device (5), and is configured to be driven by the reciprocating oscillating rotational movement to oscillate along a vertical or horizontal axis of oscillation of the work tool (7), wherein the middle angular position of said work tool (7) with respect to the drive shaft (8) is adjustable, wherein the drive device (5) comprises one of an electric actuator or a heat engine, wherein the work tool (7) is mounted laterally, or on one side of, said head (6), wherein the work tool (7) is mounted on a projecting part (8′) of the drive shaft (8), said projecting part (8′) projecting outside of the housing of the head (6), and wherein the work tool (7) is mounted to the projecting part (8′) by means of an intermediate part (11) that is directly and rigidly attached at a first end to the drive shaft (8) and directly attached at an opposite second end to the work tool (7).
