Abstract
The invention relates to a beating mechanism for grape-gathering operations. Two beaters (5) and (6), disposed opposite each other, and constituded by whips (8), are imparted transverse motions defined by the throws of two cam members (10) and (17) of a beating mechanism. The motions, which have identical periods, differ in phase on two opposite beaters. The mean spacing between the points (9) is at a maximum; said spacing varies according to a law, in order to avoid breaking the branches, while ensuring that the grapes are duly taken down.
Claims4
In a mobile grape gathering machine of the type wherein a generally inverted U-shaped structure passes over at least one row of vine stocks, said structure having at least two beating devices with a plurality of flexible rods emanating therefrom to beat or shake the vine stocks to remove the graps therefrom, mounted within said said inverted U-shape, the improvement wherein each beater mechanism comprises:
- a. a rod carrying plate to which is affixed one end of each of the plurality of flexible rods, said rod carrying plate having an integral crank pin extension with a first circular opening therethrough,
- b. a lever having a first end rigidly affixed to said rod carrying plate and a second end,
- c. a connecting rod having a first end pivotally attached to said second end of said lever, and a second end having an integral enlarged portion with a second circular opening therethrough,
- d. a first spindle pivotally attached to said inverted U-shaped structure,
- e. a first eccentric rigidly affixed to said first spindle and rotatably mounted within said first circular opening,
- f. a second spindle pivotally attached to said inverted U-shaped structure,
- g. a second eccentric rotatably mounted within said second circular opening, and
- h. means to rotate said first and second eccentrics, in the same direction to cause said rod carrying plate to translate along a curved path with respect to said U-shaped structure.
