Abstract
Description
La présente invention concerne un système de protection des vergers d'arbres notamment fruitiers contre les intempéries telles que la grêle par exemple et le matériel de mise en oeuvre du dit système. The present invention relates to a system for protecting orchards of trees, in particular fruit trees, against bad weather such as hail for example and the equipment for implementing said system.
I1 est convenu de protéger les vergers au moyen de filets. De manière connue, des poteaux doivent être implantés à distance régulière par exemple tous les douzes mètres dans chaque rangée d'arbres. Les poteaux à l'extrêmité de chaque rangée sont ancrés au sol. He agreed to protect the orchards with nets. In known manner, posts must be installed at regular distance, for example every twelve meters in each row of trees. The posts at the end of each row are anchored to the ground.
Un cable de partage relie les poteaux de chacune des rangées d'arbres et des cables transversaux relient les poteaux entre eux de préférence à une hauteur inférieure à celle des rangs des poteaux. A sharing cable connects the posts of each of the rows of trees and transverse cables connect the posts together preferably at a height less than that of the rows of posts.
Les filets sont ensuite tendus sur le cable de partage et fixés sur les cables transversaux. La réalisation de tels systèmes de protection est particulièrement longue mais elle est également très coûteuse, le prix de revient étant de l'ordre de cent vingt mille francs TTC à l'hectare couvert.The nets are then stretched over the sharing cable and fixed on the transverse cables. The realization of such protection systems is particularly long but it is also very expensive, the cost being of the order of one hundred and twenty thousand francs inclusive of tax per hectare covered.
La présente invention vise à réaliser un système
de protection des vergers d'arbres fruitiers contre les intempéries au moyen de filets et le matériel de mise en oeuvre dudit système qui soit tout aussi efficace que l'art antérieur et qui soit de mise en oeuvre plus simple et surtout moins coûteuse puisque les études réalisées par l'inventeur ont permis de chiffrer le coût entre vingt à vingt cinq mille francs TTC l'hectare couvert ; à cet effet, ledit système utilise des filets qui reposent sur la frondaison des arbres, chacun des filets d'une rangée étant lié à des branches de rangées d'arbres adjacentes à celles supportant le filet.The present invention aims to achieve a system
for protecting orchards of fruit trees against bad weather by means of nets and the equipment for implementing said system which is just as effective as the prior art and which is simpler and above all less costly to implement since the studies carried out by the inventor made it possible to calculate the cost between twenty to twenty five thousand francs inclusive of tax per hectare covered; for this purpose, said system uses nets which rest on the foliage of the trees, each of the nets of a row being linked to branches of rows of trees adjacent to those supporting the net.
Suivant encore une autre caractéristique de l'invention, le ou les tronçons de filets successifs de chacune des rangées d'arbres présente une pente de chaque côté de la rangée facilitant l'écoulement, les pentes de deux rangées de filets pouvant être réunies. According to yet another characteristic of the invention, the section or sections of successive threads of each of the rows of trees has a slope on each side of the row facilitating the flow, the slopes of two rows of threads being able to be joined.
Suivant encore une autre caractéristique de l'invention, le filet de chaque rangée d'arbres repose sur un fil de partage tendu au-dessus des arbres axialement à une rangée d'arbres et le filet chemise chaque rangée d'arbres en reposant sur ses branches. According to yet another characteristic of the invention, the net of each row of shafts rests on a sharing wire stretched above the shafts axially to a row of shafts and the thread sleeves each row of shafts by resting on its branches.
D'autres avantages et caractéristiques de l'invention apparaîtront à la lecture de la description ci-après d'une forme de réalisation de l'invention donnée à titre d'exemple non limitatif et illustrée par les dessins joints dans lesquels - la figure 1 est une vue en coupe du système de protection selon une première forme de réalisation, - la figure 2 est une vue en coupe du système de protection selon une autre forme de réalisation, - la figure 3 représente un engin dérouleur de filet selon la forme de réalisation de l'invention représentée à la figure 1, - la figure 4 schématise la mise en oeuvre du système selon la figure 2, - la figure 5 représente une vue partielle du dispositif selon la figure 4. Other advantages and characteristics of the invention will appear on reading the following description of an embodiment of the invention given by way of non-limiting example and illustrated by the accompanying drawings in which - Figure 1 is a sectional view of the protection system according to a first embodiment, - Figure 2 is a sectional view of the protection system according to another embodiment, - Figure 3 shows a net unwinding machine according to the form of embodiment of the invention shown in Figure 1, - Figure 4 shows schematically the implementation of the system according to Figure 2, - Figure 5 shows a partial view of the device according to Figure 4.
En figure 1 sont représentées schématiquement deux rangées d'arbres 1-2 dont les frondaisons, branches et feuilles sont indiquées par le répère 3. In FIG. 1 are diagrammatically represented two rows of trees 1-2, the foliage, branches and leaves of which are indicated by reference 3.
L'espacement de chaque rangée est de l'ordre de quatre mètres. The spacing of each row is of the order of four meters.
Selon l'invention, sur chaque rangée d'arbres, un filet 4 est disposé qui repose sur le sommet 5 desdits arbres. According to the invention, on each row of trees, a net 4 is arranged which rests on the top 5 of said trees.
Selon l'invention, chacun des filets présente une pente de chaque côté de l'axe de la rangée pour faciliter l'encombrement et l'évacuation notamment de la grêle. According to the invention, each of the nets has a slope on each side of the axis of the row to facilitate the space requirement and the evacuation in particular of the hail.
Chacun des filets est relié par des liens 6 de qualité adaptés à des branches charpentières de rangées d'arbres adjacentes de niveau inférieur pour ménager ladite pente. Each of the nets is connected by links 6 of quality suitable for carpenter branches of rows of adjacent trees of lower level to spare said slope.
Ce système de protection fait jouer aux arbres le rôle de charpente support des filets, ce qui évite le montage de piquets et fils ou câbles tendus de l'art antérieur. I1 est destiné à être appliqué à des arbres âgés et de ce fait suffisamment charpentés pour supporter le poids de la grêle. This protection system makes the trees play the role of support structure for the nets, which avoids the mounting of stakes and tensioned wires or cables of the prior art. I1 is intended to be applied to old trees and therefore sufficiently structured to support the weight of hail.
La mise en oeuvre de ce mode de réalisation est effectuée comme représenté schématiquement en figure 3. The implementation of this embodiment is carried out as shown diagrammatically in FIG. 3.
Un véhicule tracteur de tout type connu est pourvu d'une flèche ou bras 7, avant ou arrière avec un axe horizontal déporté sur lequel est empilé un rouleau 8 constitué par le filet 4. Le rouleau du fait du déport de l'axe horizontal est transversal à l'axe longitudinal de la rangée d'arbres. A tractor vehicle of any known type is provided with an arrow or arm 7, front or rear with an offset horizontal axis on which is stacked a roller 8 formed by the net 4. The roller due to the offset of the horizontal axis is transverse to the longitudinal axis of the row of trees.
L'extrémité du filet est fixée au bout de la rangée d'arbres par exemple sur le premier arbre de la tête. The end of the net is fixed to the end of the row of trees, for example on the first head tree.
La tension du filet est obtenue par les cordes 6 régulièrement espacées reliant les bords du filet avec les branches charpentières des rangées d'arbres adjacentes. The tension of the net is obtained by the regularly spaced strings 6 connecting the edges of the net with the carpenter branches of the adjacent rows of trees.
La liaison des filets parallèles entre eux s'effectue à distance régulière, par exemple tous les 1,20 mètres au moyen de crochets de forme adaptée. The parallel nets are connected to each other at a regular distance, for example every 1.20 meters by means of hooks of suitable shape.
A l'extrémité du rang, le filet est attaché par tous moyens connus au dernier arbre. At the end of the row, the net is attached by all known means to the last tree.
L'exemple de réalisation de l'invention représenté à la figure 2 est adapté aux vergers dont les arbres, encore jeunes sont associés chacun à un piquet tuteur et sont de structures trop faibles pour pouvoir supporter directement le poids de la grêle retenue par le filet 4. The embodiment of the invention shown in Figure 2 is suitable for orchards whose trees, still young, are each associated with a stake stake and are too weak structures to be able to directly support the weight of hail retained by the net 4.
Dans ce mode de réalisation un fil ou cable de partage 9 est tendu au-dessus et le long de la rangée d'arbres suivant son axe longitudinal. Sur ce fil ou cable de partage 9 est disposé le filet 4 qui repose sur les côtés des arbres en chemisant la rangée d'arbres. In this embodiment, a sharing wire or cable 9 is stretched above and along the row of trees along its longitudinal axis. On this sharing wire or cable 9 is disposed the net 4 which rests on the sides of the trees by lining the row of trees.
Dans ce mode de réalisation, le fil ou câble de partage est fixé avantageusement aux piquets tuteurs.In this embodiment, the sharing wire or cable is advantageously fixed to the stake stakes.
La largeur du filet est calculée en sorte que soit chemisée la totalité des branches et feuilles. La fixation du filet s'effectue au moyen d'une tige, non représentée pour simplifier le dessin, enroulée horizontalement dans l'extrémité inférieure du filet, de place en place et reliée par un ou plusieurs liens aux troncs des arbres de la rangée correspondante. The width of the net is calculated so that all the branches and leaves are lined. The net is fixed by means of a rod, not shown to simplify the drawing, wound horizontally in the lower end of the net, from place to place and connected by one or more links to the trunks of the trees of the corresponding row .
Dans cet exemple de réalisation, il est possible d'utiliser un filet de plus faible résistance mecanique que dans le cas de la figure 1, ce filet pouvant être de type extrudé. Ce mode de réalisation nécessite des filets de plus grande largeur que dans le cas de la figure 1. In this exemplary embodiment, it is possible to use a thread of lower mechanical strength than in the case of FIG. 1, this thread being able to be of the extruded type. This embodiment requires nets of greater width than in the case of FIG. 1.
En figure 4 est représentée la mise en place du système de protection selon la figure 2. Dans ce mode de mise en oeuvre, il est fait usage pour chaque rangée d'arbres de deux véhicules pourvus chacun d'un rouleau dévideur 10 vertical. Le filet est enroulé sur les deux rouleaux et tendu entre-eux, chacun des véhicules et des rouleaux correspondants venant de part et d'autre de la rangée. In FIG. 4 is shown the installation of the protection system according to FIG. 2. In this embodiment, use is made for each row of shafts of two vehicles each provided with a vertical reel 10. The net is wound on the two rollers and stretched between them, each of the vehicles and corresponding rollers coming from either side of the row.
Par avancement du véhicule, le filet est déroulé. By advancing the vehicle, the net is unwound.
On peut également concevoir que, comme représenté, soient utilisés deux véhicules avec chacun un rouleau vertical dans les rangs de rives du verger et dans les rangs intérmédiaires un ou des véhicules avec des rouleaux verticaux.It is also conceivable that, as shown, two vehicles are used with each a vertical roller in the rows of banks of the orchard and in the intermediate rows one or more vehicles with vertical rollers.
On peut également concevoir sans sortir du cadre de l'invention que les filets de chacun des rouleaux 10 sont en une seule bande indépendante des autres bandes des autres rouleaux, lesdites bandes étant reliées entre elles par tout moyen connu au sommet de la rangée d'arbres. It is also conceivable without departing from the scope of the invention that the threads of each of the rollers 10 are in a single strip independent of the other strips of the other rollers, the said strips being connected together by any known means at the top of the row of trees.
