Definitions

  • the object of the invention is a method for removing buds in branch cordon vine system, for controlling vine condition, shoot vigour, yield and fruit quality.
  • the vine-growing, training and yield control method known as "minimal pruning" achieves yield control by the cutting back or shortening drooping shoot systems.
  • the method has proven to be successful for producing ordinary wines.
  • the need for improved fruit quality has called for the development of a new yield control method (Bab ⁇ , Hungarian patent No. 220,386 Bl / 1998) that performs the task by utilising a machine for hedge-like trimming of the branch system and thinning main buds after bud pushing. Adjusting the width of the thinned zone enables the method to control vine condition, shoot vigour, and the number of shoots in addition to performing yield control. In adequately trained vineyards, where the tasks described above are performed using machines, hand pruning is no longer needed.
  • the operation of the yield control machine is facilitated in branch cordon vine systems by a vertically positioned branch system.
  • a vertically positioned branch system it is advantageous to fix future fruiting canes depending vertically downward from the cordon arm to vertical wires of the trellis.
  • the cordon arm should be 190 centimetres above the ground, with the vertical wires (and fruiting canes) being equally spaced, e.g. 25 centimetres apart.
  • the bud load of the vines can be adequately tuned to the varying fertility of the ground, even during the treatment.
  • Bud removing is carried out in the upper zone of the vertically positioned branch system, in the proximity of the cordon arm.
  • Nine load is controlled by adjusting the width of the treated zone.
  • US patent No. 4,257,213 discloses an apparatus fitted with rotary brushes for removing buds and shoots. Brushes are pressed against the branch system while rotating about a vertical axis. This machine, however, cannot be used in branch cordon vine systems. The reason for that is that fruiting shoots of a branch cordon vine system are positioned vertically, and, because efficient bud removal in such a system would require the brushes to enter the branch system and track vertical shoots downwards, brushes with bristles moving in horizontal planes are unable to efficiently carry out the bud removing treatment. In addition, as bottom parts of fruiting shoots in a branch cordon vine system are not fixed, brushes rotating about vertical axes will inevitably dislodge them, or, still worse, wind them around the brushes.
  • Our invention is therefore a method for removing buds in branch cordon vine systems for controlling vine condition, vigour, yield and fruit quality.
  • Main buds of the branch system are removed from the upper portion of the vine after bud pushing but before wood formation starts at shoots springing from main buds, using an implement supported on a moving tractor, with the implement comprising rotating sickles and/or a brush treating device undergoing rotational or rotational and reciprocating motion.

  • a further preferred way of carrying out the inventive method is characterised by that main buds of the vine are removed by a brush treating device that has its principal axis set so that it inclines into the direction of the advance of the tractor and/or in a direction perpendicular thereto.
  • a still further preferred way of carrying out the inventive method is characterised by that main buds of the vine are removed by a brush treating device comprising bristles arranged along several planes to form edge brushes, where said planes are perpendicular to the axis of rotation of the brush treating device.
  • Another preferred way of carrying out the inventive method is characterised by that main buds of the vine are removed by a brush treating device comprising bristles arranged in an acute or obtuse angular position with respect to the axis of rotation of the brush treating device.

  • the bud removing apparatus consists of two main units: the bud removing means and the motive and mounting means that support the bud removing means.
  • the apparatus can be produced as a modular combination of these units.
  • the bud removing means can consist of cutter, beater, and brusher modules, with the number of modules being dependent on requirements of technology.
  • the units can at the same time be operated separately.
  • the bud removing means is preferably driven by a hydraulic motor.
  • the implement is mounted on the tractor by a mounting means.
  • the mounting means is responsible for eliminating jolts and swings caused by ground bumps or the steering of the tractor, thereby stabilising the position of the bud removing means.
  • the mounting means also adjusts the position of the bud removing means to adapt to the changing width of the branch system as the tractor proceeds.
  • the self-centering mounting means provides for keeping a pre-set distance between the branch system and the brush structure. Without self-centering the brush structure enters the branch system to an undesirable degree, which can result in an uneven rotation of the brush.
  • Dimensions (width and length) of the implement are dependent on the type of the tractor and implement, on the place and method of mounting, and on characteristics of the vine system (distance of rows, height of the branch system).
  • the mounting means of the implements are fabricated of angular, preferably closed section steel of suitable gauge and strength.
  • the mounting means of the preferred embodiments of the implements according to the invention is similar to the implement mounting device applied in . a vine topping machine made by Csorna-Hantech in Hungary (type: SN-05-500-1).
  • the implement can be mounted on the side of the tractor, or alternatively it can be attached to the 3 attachment points (Fig. 5) on the rear thereof. In the latter case, owing to the three-point suspension, the tilt angle of the implement becomes adjustable, which makes it possible to set the vertical position of the bottom part of the implement.
  • the vertical position of the brush treating device is adjusted by means of a hydraulic cylinder in parallel combination with a vertical column.
  • a “self-centering” version of the mounting means can also be conceived (Figs. 8-13).
  • the "self-centering" design provides for keeping the degree of penetration of the brush structure into the branch system within established limits.
  • the self-centering mounting means shown in Figs. 6-8 is mounted on the 3 hydraulically operated attachment points on the rear of the tractor.
  • the bud removing means presses against the branch system under its own weight, while the average distance of the bud removing means and the branch system remains adjustable.
  • the penetration depth of the brush bristles into the shoot system can be adjusted against a spring, and the vertical position of the brush treating device 6-8 is also adjustable.
  • the mounting means keeps the bud removing means suspended above one row or multiple rows of vines (9-13).
  • the mounting means extends from the tractor towards the vine row, reaching above the branch system of the vines.
  • the brushing implements arranged along substantially parallel axes, depend from the mounting means on both sides of the row, "hanging" downwards. Implement positions are adjusted by the mounting means so as to follow the path of the vine row.
  • the mounting means is designed to enable the adjustment of the relative distances of the brush structures: brush structures may move relative to one another within the limits set by limiter arms, the movement being guided and restricted by springs and dampers.
  • An embodiment of the mounting means can simultaneously operate on multiple vine rows (Figs. 9-11).
  • the inventive apparatus can contain a mounting means that is different from the ones set forth above.
  • a mounting device that is different from the ones set forth above.
  • the mounting device described in US Patent No. 6,374,538 Bl (Sheet 57), or a machine produced by Andros Engineering, USA, CA ("over-the-vine tool carrier") can also be applied.
  • the cutting device thereof can be replaced by implement III of the present invention, providing for operation on both sides of the vine row.
  • Attaching the bud removing apparatus to a gantry-type tractor can be also advantageous.
  • the motive and mounting means of the invention should of course be adapted to it (Fig. 26).
  • the cutting means of the yield control apparatus can follow two different designs.
  • a cutting means is formed by the edge brush itself, which can be complemented with sickles or saws.
  • the cutting means rotates about an axis.
  • Rotary sickles are mounted so that they conform to the path of the edge brush.
  • Stationary finger bars or stationary sickles
  • rotary cutting means employing only the reaction of the brush structure or the plant itself can be conceived.
  • the principal structure of the cutting means is known art by itself, but the cutting means comprising rotary sickles cooperating with the brush structure is a novelty.
  • the cutting means for separating fruiting shoots can be implemented in two varieties, with the axis of rotation of the cutting means being either a) coincident with (implements I/c, I/d, Il/a) or b) distinct from (implements I/a, I/b, Il/b, Il/d, and III) the axis of the brush structure.
  • Buds (or, occasionally, short shoots with a length of about 10-15 cm) are removed by brush bristles.
  • the length of the bristles can be in the range of 5-250 mm (exceptionally 450 mm), with their diameter falling between 0.5 and 3 mm, and preferably being 1-2 mm.
  • Bristles are arranged either in a "scattered" configuration, or are grouped into clusters of a few or into rows or zones.
  • the brush formed thereby constitutes a brush structure together with the brush shaft.
  • the brush structure consists of structural elements that attach the brush to the brush shaft.
  • the brush is preferably attached to a tubular element (or, alternatively, to the brush shaft itself).
  • Bristles arranged in zones or bands constitute an "edge brush,” which can take the shape of a brush wheel (with the outline of the bristles forming a disc that falls into a plane perpendicular to the brush shaft), or a spiral brush. In case of the latter, bristles are arranged along a spiral around the brush shaft (Fig. 21). The width of the band of bristles of the edge brush is 1-5 cm. Bristles of the edge brush are arranged radially around the brush shaft, with, occasionally, some of them "slanting" laterally, out of the plane of the edge brush. Between the individual bands of the brush there are either no bristles or the bristles are very short (Fig. 15).
  • Edge brushes of the described art comprise a structural element that forces bristles against the branch system during the operation of the apparatus.
  • the short bristles can be positioned so that they incline tangentially in the direction of rotation.
  • Bristle-free zones cause the branch system to undergo a wave-like motion, enhancing the efficiency of bud thinning.
  • an edge brush comprising bristle-free sectors can also be conceived (Fig. 16).
  • Brush shafts and brush structures attached thereto are driven by a hydraulic motor either directly or through a drive gear.
  • Bud thinning action of the brush structure on a given area of the branch system varies as a function of the distance of the brash shaft from the area in question.
  • the brush structure acts with optimal efficiency on a 20 cm- wide tract of the branch system, collinear with the brush shaft. Areas further than that can receive only partial treatment.
  • the bud thinning impact can be enhanced by the "shearing" effect that results from the rotation of neighbouring, parallel brash structures. In this case both brush structures efficiently act with the whole area of their vertical projections on the branch system.
  • Implement I can be used in cooperation with different cutting-brushing means. Its suspendible version is suitably mounted on the front of the tractor.
  • the cutting means of the implement "cuts to size" the top and sides of the branch system, while the brushing means operates on the top zone of the branch system.
  • the implement is applied for controlling vine condition and shoot vigour. Nine condition is adjusted by shortening canes, whereas shoot vigour is controlled by thinning swelling main buds.
  • the implement can be applied for shoot thinning as well: in the proximity of the cordon arm, where the shoot system is prone to growing thick, shoots are thinned by the implement before the start of wood formation.
  • Implements I/a, I/b, and I/c are mounted on the side of the tractor, using a mounting means.
  • the mounting means supports a column that can be tilted in the direction of the vine row.
  • a support beam is attached to the column, with the height thereof above the ground being adjustable by means of a hydraulic cylinder.
  • the width of the treated range at the top of the branch system is also adjustable (implements I/c, I/d).
  • implements I/c, I/d In vineyards with vines having wide branch systems it is preferable to attach multiple cutting-brushing means to the topping frame of the implement.
  • the brushing-cutting means of the apparatus is identical to that of implement I/b.
  • This embodiment of the inventive apparatus is to be used primarily in "minimal pruning" systems (Figs. 25, 26).
  • Implements according to the invention are adjusted to match the width and height of the branch system. In addition, it is possible to adjust during the operation of the apparatus
  • Implement II operates on the sides of the branch system. It should be dimensioned with regard to the width of the tractor and the row spacing of the vine system.
  • the implement is preferably mounted on the side of the tractor, suspended to the section between the front and rear wheels. This mounting position, however, frequently puts limits to the length and width of the implement. When operating between closely spaced rows, only the efficiently operating parts of the brushes can extend from the plane of the wheels of the tractor towards the vine row.
  • the implement can also be mounted on the rear of the tractor, using three-point suspension. In that case the implement fits easily in the space between the rows, which makes this mounting position suitable for systems with closely spaced rows.
  • a gantry-type mounting means that arches over the row. This mounting means is preferably mounted on the side of the tractor between the front and rear wheels.
  • the implement is used for yield control as well as controlling the number of shoots and vine condition. It applies an edge brush as brushing means, and can also be fitted with a cutting means that "cuts its way” through the fruiting shoots.
  • the implement is shown in Fig. 4 with a simplified motive and mounting means.
  • the support column of the mounting means is attached to the tractor by an adjustable-length support frame F.
  • the column supports a cutting (or beating) means and a brushing means.
  • the vertical position of the cutting (beating) and brushing means can be adjusted by means of a hydraulic cylinder, with the horizontal projection thereof being at the start parallel with the direction of advance of the tractor. During operation the angular position of the implement can be modified.
  • the brushing means is best kept parallel with the row, but in case of a row where the width of the branch system varies the front of the apparatus should be further removed from the branch system. This enables the brushing means to guide the branch system towards the brushes (Fig. 1).
  • cordon arm of a branch cordon vine system is 190 cm above the ground.
  • Implement II can be used for shoot thinning, that is, thinning 5-20 cm-long shoots in the proximity of the cordon arm. In older vineyards the same task is preferably performed by implement II/c.
  • the column G of the apparatus When performing yield control operations using implement Il/a, the column G of the apparatus is tilted forward, in the direction of advance of the tractor (Fig. 4). The tilt angle of the column G of the support frame F can be adjusted and locked.
  • the column G supports a brushing means. (If needed, as an addition, sickles can be mounted on the shaft of the brushing means.
  • Fig. 4 shows the path of the contour of the sickles.)
  • the brush structure is made up of three parts. Brushes are arranged along three independent shafts supported in a frame, each shaft being fitted with bearings at both ends (Fig. 23).
  • implement II/c The motive and mounting means of implement II/c is similar to that of implement Il/a, but implement II/c does not have a brash structure. It comprises beater rods, or, optionally, a cutting means comprising swinging or stationary sickles, arranged on multiple parallel shafts supported below one another on the support beam of the implement.
  • the speed of rotation of the implement can be easily optimised, and, having no brash structure, the implement can be rotated with significantly higher speeds than previous ones.
  • Implement II/c is usually mounted behind implement I on the tractor.
  • An apparatus thus configured is advantageously used for controlling/limiting vine condition and shoot density.
  • brush bristles and sickles or beater rods move downward along the branch system opposite the orientation of shoots and buds, following a nearly vertical path.
  • Moving bud removing means draw the branch system downward and towards the implement against its suspension to the cordon line, helping the penetration of the implement among the fruiting shoots.
  • the angle between the horizontal projection of the brush shaft and the vine row is adjustable, which provides for "forcing" the brush structure among fruiting shoots extending from the contour of the branch system.
  • the speed of rotation of the bud removing means corresponds to the translational speed of the tractor. Controlling the rotational speed of the instrument in such a way ensures that fruiting shoots are kept in a nearly vertical position even if the speed of the tractor varies.
  • the bud removing efficiency of single-shaft brash stractures is greater in the proximity of the shaft than in areas further away.
  • Moving brash bristles guide "protruding" fruiting shoots before the apparatus.
  • the cutting and beating means can be separated from the brash structure.
  • the inventive cutting, beating and brushing means enable the apparatus to adapt to technological requirements and changing demands of the working environment.
  • the inventive apparatus can perform yield control and vine condition adjustment operations on patches of ground of different fertility.
  • shoot density can be lowered using a single-shaft brush stracture with the shaft set horizontally.
  • Implement III is primarily used for yield control. As it can be seen in Fig. 1, the suspended variant of the implement is mounted on the side of the tractor in a similar way to what has been described relating to implement II. It is preferable to use a mounting means that enables the implement to operate on both sides of the vine row simultaneously. When operating on both sides of the row, the bud thinning impact of the implement is improved by the antagonistic alternating motion of brush structures supported on substantially vertical shafts.
  • Fig. 1 is the top plan view of the implements according to the invention, with Fig. 2 showing the front view and Figs. 3-4 showing the side views thereof.

  • support arms TAK are connected to horizontal beam VG through rotary stop pins FHK.
  • a hydraulic jack can be disposed between the support arm TAK and the horizontal beam VG for adjusting vertical position of the implement KNN.
  • suspenders FUK are mounted so that they rotatably depend from said support arm at different angles in such a way that the bottom support arm ATA is in non-parallel position relative to support arm TAK.
  • the bottom support arm ATA there are swinging arms LEK rotatably connected to said support arm ATA, with brush support frames KFK being hinged to the swinging arms LEK at both sides of the support arm ATA.
  • Brush structures are supported in the brash support frames in bearings, so that the brashes can be rotated by a drive.
  • Dampers LCS are disposed between the swinging arms LEK and between swinging arms LEK and the brash support frames KFK.
  • the contracting, "scissoring" motion of the swinging arms LEK is limited by an adjustment rod AR acting against a spring RUG for swinging arms disposed rearward, while the degree to which the forward disposed swinging arms LEK are drawn together is determined by the hydraulic cylinder H, so the swinging arms LEK can be expanded before starting the treatment on a new row.
  • the swinging arms LEK are able to move against the spring RUG and the damper LCS during the operation of the implement KNN.
  • Figs. 9-13 Rough compensation of level difference between vine rows on the two sides of the tractor is provided for by the two horizontal beam that can be elevated independently of each other.
  • a hydraulic cylinder is included between the horizontal beam NG and the implement KVV.
  • the hydraulic cylinder should be disposed such that it enables the implement KVV to turn about its suspension point to a limited extent, which improves the capability of the apparatus to follow branch cordon rows accurately despite the rocking, wobbling motion of the tractor.
  • suspenders FUK of the implement KVV provide for more exact tracking of rows in case row spacing is not constant or the tractor is wobbling or rocking. Swinging arms LEK ensure that the spacing of the brush support frames KFK from the branch system is kept optimal so that brush bristles enter into the branch system to the desired depth.
  • the operating height of the implements KVV is controlled by the vertically moving the horizontal beams VG. In the upper terminal position of the horizontal beams VG the implements KVV can be lifted off the rows.
  • the horizontal beams VG can be turned into a position parallel with the direction of advance of the tractor, preferably in such a way that after being displaced slightly along the horizontal beam VG the implements KVV get aligned beside one another.
  • Fig. 14 shows an embodiment of the driving mechanism of the brush treating device KF.
  • the speed of rotation of the hydraulic motor is too high compared to the desired rotation speed of the brashes, the speed of rotation is reduced between the shaft of the hydraulic motor HM and the shaft of the brushes by means of a chain and sprockets LK or using a ribbed belt drive.
  • Fig. 15 an edge brash arrangement is shown. Between the edge brashes there are zones with no bristles at all or zones comprising densely packed shorter bristles. Bristles may be arranged in a radial position with respect to the support shaft or in inclining positions, slanting laterally out of the plane of the edge brush, or slanting tangentially either into the direction of rotation or oppositely.
  • the aim of both the edge wheel brash and the spiral brash arrangements is to make bristles enter deeper into the branch system and remove deeper laying buds and shoots.
  • Fig. 16 shows a perspective view of the clustered-bristle edge brush arrangement.
  • This arrangement can be derived from the edge wheel brash by dividing individual edge brash discs into sectors comprising bristles on the one hand and bristle-free sectors on the other. Bristled and bristle-free sectors can occupy identical or different angular regions. Bristles can be arranged in a way that they slant forward, backward, or sideways with respect to the brash shaft. The angular position of bristle-free sectors in neighbouring edge brushes can be identical or different.
  • Bristle-free sectors help penetration into the branch system and the forward motion of the brush in the direction of the brush axis, so that the brush can "skip" to the next section of the freated branch system.
  • the section comprising bristles engages the branch system, it sets the treated section of the branch system into motion, which helps bud removing.
  • Fig. 17 shows brush stractures KFSZF that are supported on nearly vertical shafts and undergo antagonistic reciprocating motion.
  • the brush structure consists of cup brushes. Cup brushes are clamped together by nuts disposed at the ends of the brush shaft. If fasteners are slightly loosened, brush cups can be freely rotated, independently of each other.
  • the stracture comprises a brash cup KT and plastic brash adapter KB sandwiched between a bottom clamping plate A and an upper clamping plate TSZ, and a distance piece BH applied for distancing the bottom clamping plate A and the upper clamping plate TSZ.
  • Brush shafts can be supported, driven and controlled in a way that they depend downwards from a horizontal support means. This arrangement provides for simultaneous operation of the apparatus on both sides of the vine row.
  • the horizontally disposed camshaft B moves follower E and the brash shaft T together with the brush structure by means of an eccentric cam EX as shown in Fig. 18.
  • the camshaft B is driven by a hydraulic motor.
  • the distance of the cam EX from the shaft T is adjustable, which makes it possible for the camshaft B to cause the brush structure to rotate slower of faster against frictional forces.
  • the speed of rotation of the brush shaft T should be adjusted so that the brush rolls on the branch system with a speed proportional to the speed of advance of the tractor. Bristles penetrate the branch system like needles.
  • the implement can be designed with brush shafts of adjustable relative distance. Distance between the brush shafts should be tuned to the width and density of the branch system: with brash shafts placed closer or with brushes with overlapping motion paths a better brushing effect can be attained.
  • Figs. 19 and 20 illustrate a suitable brush arrangement.
  • Fig. 21 illustrates a double-start spiral edge brush KFSP.
  • the number of spiral "threads" of the brash varies as a function of fruiting shoot density. Higher fruiting shoot density values require more "threads.”
  • Double-start spiral edge brushes are used in case the fruiting shoots are about 25 cm apart on the cordon arm. In that case the edge brush penetrates among the fruiting shoots and separates them, an effect that is intensified by the application of a more densely packed brush with harder, thicker bristles. The edge brush "cuts its way” through thinner shoots.
  • Sickles operate "optimally" at higher rotational speeds than the rotary edge brash. Therefore, diverging criteria are set for the speed of rotation of the brush shaft T.
  • an implement comprising only sickles (implement II/c) especially for cutting "long-thick" canes connecting fruiting shoots.
  • the implement can also be utilised in ageing vineyards for shoot thinning, and for bud thinning on fruiting shoots. In the latter case sickles are replaced with flexible beating means.

  • the shaft T supporting the (cutting-) brushing means is perpendicular to the column G.
  • the column G is surrounded by a slide CSK.
  • the shaft T is mounted on the side of column G facing the vine row.
  • the shaft T is attached to the slide CSK by means of a bearing housing CSH.
  • a tubular member CSI is connected to the shaft T, with said tubular member CSI carrying an edge brash.
  • the shaft T is rotated by a hydraulic motor HM drive.
  • the shaft T extends through the full length of the tubular member CSI. Because the column G is tilted, the centre of gravity of the implement is shifted.
  • the column G should be of adequate strength. (A closed section member is of suitable strength. Its length depends on the height of the branch system, in the vineyard according to our example it is preferably 240 cm.)
  • the total length of the tubular member that is attached to the column is set by the height of the branch system, or by the width of the track to be treated.
  • the length of the brush stracture should be greater, whereas in the opposite case it should be smaller.
