  • Patent number: 5002135
    Abstract: A portable electric tool, such as, for example, shears or secateurs suitable for pruning and/or harvesting work, comprises at least one moving working component disposed at the front and of a hollow frame one part of which forms the handle of the tool and inside which are housed an electric motor and a speed reducer. The outlet of the speed reducer is connected to the moving working component by means of a transmission system which comprises a moving gear unit. The tool also includes a trigger which protrudes outside the frame and operates an electric control device. The trigger and the electric control device are connected to the moving gear unit of the moving working component and follow the movements of the component. The trigger and the control device can occupy different relative positions, so that each movement made by the trigger from a neutral position, activates the control device, which in turn starts the electric motor to move the whole unit: i.e.

  • Patent number: 4989365
    Abstract: A machine for training plants to be supported between two lifting wires positioned one to each side of a row of such plants. The machine includes a head comprising first and second lifting means for raising from ground level the aforesaid lifting wires and plant vegetation to be supported therebetween, first and second guide means positioned behind the lifting means in the intended direction of travel of the machine for guiding and drawing together the raised lifting wires, and connection means positioned behind the guiding means in the intended direction of travel of the machine for interconnecting the raised lifting wires. The arrangement is such that, in operation of the machine, the said first lifting means and said first guide means are positioned on one side of said row of plants and said second lifting means and said second guide means are positioned on the other side of said row of plants.

  • Patent number: 4975016
    Abstract: An automated machine comprising a handler mounted with a rotating aptitude about two perpendicular and intersecting rotational axes, having a free end fitted with a mechanical hand comprising an intake head. A vision system is permanently installed at the point of intersection of the rotational axes in a base unit comprised of a cradle which supports a rotatable turret which has an extension arm attached to another end of the handler. The handler is comprised of two branches comprising a folding arm that are joined together at one end with devices provided for symmetrical movement of both branches when an external force is exerted on either of them. The automated machine contains devices for deployment and retraction of its folding arms so as to grasp and release an object detected by the vision system installed in the handler apparatus.

  • Patent number: 4733525
    Abstract: A cutting machine for use in agriculture, viticulture and arboriculture has at least one cutting assembly constituted by a plurality of superposed cutting tools, each cutting tool comprising a rotary circular cage provided with peripheral openings, and a member disposed in the cage and taking part in the cutting action, the improvement being that the cage and the member disposed therein are made in a complementary manner and are associated so as to constitute a system of blade and counter blade producing a cut by shearing action.

  • Patent number: 4644648
    Abstract: A portable hydraulic tool, such as a hydraulic secateurs, is of the kind having a single acting ram including a driving piston with its piston rod connected to at least one movable operating member such as a cutting element of the tool, the piston being movable in fluid tight manner in a bore under the thrust of hydraulic fluid acting on a working face of the piston, the improvement being that there is provided a return chamber the volume of which decreases when the driving piston is displaced in its working stroke, the return chamber containing a compressible fluid under pressure such that, when the thrust exerted on the piston by the hydraulic fluid becomes less than the thrust exerted on the piston by the compressible fluid, the piston is caused to carry out a return stroke by the expansion of the compressible fluid.

  • Patent number: 4359821
    Abstract: A hydraulic secateur or pruning shears includes a device for continuously and smoothly controlling the separation of its cutting blades. This avoids the disadvantage inherent in conventional hydraulic-assisted pruning shears, in which the cutting blades must either be open completely or closed completely, resulting in the entanglement of branches and other undesirable objects with the cutting blades. The controlling device includes a trigger, distribution apparatus for pressurized fluid, an inlet for the fluid and an outlet for the fluid. At least one of the blades is pivotable and activated by hydraulic apparatus. The blades can be set and maintained at any position between the two extreme positions.
