Abstract:
A vine or cane pruning apparatus, comprising a toothed wheel for guiding the pruning apparatus over vegetation in use, the wheel comprising a multiplicity of generally radially projecting teeth distributed about the periphery of the wheel for catching vegetation between gaps of the teeth, and wherein the wheel rotates by consequence of its engagement with the vegetation and vine or cane posts as the apparatus is driven along a row of vines or canes for pruning; and a driven rotary cutter mounted co-axially to the wheel for cutting vegetation caught between the teeth, the cutter being configured such that its effective cutting area falls within the diameter of the wheel.
Abstract:
The invention relates to devices and methods for removing twigs, in particular canes, which have been cut from plants, in particular vines, growing in an espalier but which continue to be retained in the espalier and at least partly protrude from the top of the espalier.
Abstract:
An apparatus (20) for use in stripping irregular material (8) from a line (3, 4) during relative movement between the apparatus (20) and line (3, 4), including a material guide (50), stripping mechanism (40) and line guide (30). A first line guide element(30a), first stripping element (40a) and first material guide element (50a) collectively form a first stripping assembly and the second line guide element (30b), second stripping element (40b) and second material guide element (50b) collectively form a second stripping assembly, the line passing between said stripping assemblies during said stripping. The stripping assemblies are orientated during said stripping such that the first material guide rotation axis and the first stripping element rotation axis are on a first lateral side of the line and the second material guide rotation axis and the second stripping element rotation axis are on a second lateral side of the line.
Abstract:
The invention relates to a method for analysing the structure of cultured hedges, equally applicable by day or by night, for a mobile, continuously-moving machine in tied or staked plantations such as vineyards, characterised in that the system uses an artificial vision system (4), working by transmission, which permits a detection of the shadowing of the light between one or more transmitters and one or more detectors to one side and the other of the hedge and the information generated by said shadows of light are processed by an electronic analysis system (7), programmed or embodied to examine the elements of the structure of the hedge.
Abstract:
A double blade bar for pruning and pollarding, comprising a supporting framework (2) for a cutting blade (3) and a counter-chop blade (5) extending along a cutting direction (10), interconnected each other and being operable in alternating rectilinear movement, in opposite direction one another, along the cutting direction, passing from an open configuration of the bar in which the cutting teeth overlap the counter-chop teeth, to a closed configuration wherein each of the cutting teeth is located in a substantially intermediate position with respect to the port defined by two successive counter- chop teeth, and vice versa. The bar also comprises movement transmission means which present, on the cutting blade, an upper rack (6) which engages, by means of a cogwheel (7), a corresponding lower rack (8) associated to the counter-chop blade. The wheel is pivoted on a supporting rod (9) around a pivoting axis (20) and driven by motor means, so that in the open configuration it engages with a median portion with respect to the upper rack and a median portion with respect to the lower rack, while in the closed configuration it engages simultaneously with the upper rack and the lower rack.
Abstract:
A cutting system for plants includes opposed first cutting assemblies and opposed second cutting assemblies. The first cutting assemblies include a substantially vertical stack of cage type cutters and a lower cutter having stationary and rotating cutter members. The cage type cutters include an outer driven guard that moves the plants past the stationary cutters. Opener wheels have a diameter slightly greater than the cutters and engage posts and other objects to position the cutting assemblies and to prevent damage to the cutting assemblies and trellises. Side cutter assemblies are positioned forward of the vertical stack of first cutting assemblies and provide precision side cuts. The side cutters include stationary cutter members and rotating cutter members that provide a precise shearing action. The system rotational speed is controlled to maintain a speed proportional to the ground speed so that a substantially constant percentage of plant material is removed.
Abstract:
A programmable viticulture management system includes a mechanized device for removing excess undesired portions of plants advances through a vineyard to perform control operations on two rows or half-rows of grape vines simultaneously. Accessories mount to the mechanized device and include various engagement members for engaging the vines. A control system automatically varies the velocity of the engagement members in relation to the vehicle speed. The control system also receives various inputs and provides information on multiple growth control practices.
Abstract:
L'objet de l'invention est un procédé d'effeuillage consistant à créer un flux d'air susceptible de redresser la végétation à l'avant de moyens (16) de coupe, caractérisé en ce que le flux d'air est généré en amont des moyens (16) de coupe selon le sens d'écoulement dudit flux.
Abstract:
The invention relates to a process for pruning a row of plants supported by posts spaced by a distance d from each other along said row, using a machine comprising a straddling tunnel (5) equipped with a pruner (6) with two pruning harrows (7) disposed each respectively on one side of said tunnel and operable reversibly in an open state wherein they are moved apart, said process providing for driving the machine at a speed V along the row by placing said row within the tunnel (5) to prune it on each side between the harrows (7) and for operating said harrows in their open state upon the passage of each posts between them, the opening of the harrows (7) being operated by means of an automatic procedure (H) determined by a previous learning stage (E) using several successive manual openings (E1) of the harrows (7) to determine an opening time period (T ON ) necessary for the passage of a post at the driving speed V and an interval time period (T period ) separating said openings, said opening and interval time periods being applied during the automatic procedure (H).
