  • FIG 1 depicts an apparatus, installation or system 10 for protecting trees 12, especially from insects.
  • System 10 is typically installed in a field, such as an commercial orchard for example, where trees 12 have been planted and grow in a single-row.
  • System 10 comprises posts 14 aligned together in a row, which is itself aligned with the single-row of trees 12.
  • the posts 1 support a retractable shield 16 which extends longitudinally over the length of the row of posts 14.
  • system 10 also comprises a bottom tray 18 located below branches of the trees 12 and which snugly fit around the posts 14 the trunks 36 of the trees 12.
  • the posts 14 are installed between the trees 12, typically one post 14 between one to as many trees 12 as is convenient.
  • One section 23 of system 10 corresponds to at least one tree 12 between two adjacent posts 14.
  • the section 23, i.e. the distance between two adjacent posts 14, may be of any length For example, it can be 3, 5 or even 10 meters or more.
  • the number of plants per section depends on their size. For example, it is possible to fit more shrubs in a section 23 than trees 12. In an industrial orchard, for example, it is typical to have between one to ten trees 12 planted between each post 14, depending on the desired density, although there is no specific limit to how many plants or trees are planted between each post 14.
  • Each post 14 has lateral extensions 20 extending on both sides of the post 14.
  • Lateral extensions 20 support two lateral guides 24, each one being located on a different side of the lateral extensions 20.
  • These lateral guides 24, which may take the shape of tensioned wires, small tubes or small tubes over tensioned wires, are used to guide the shield 16 when it is deployed over the trees 12.
  • the lateral guides 24 are located at a lateral distance on each side of the row of posts 14 so that they support and spread the shield 16, when deployed, so that it substantially clears branches of the trees 12.
  • Posts 14 are fixedly interconnected by longitudinal cables 21 running along the length of the row of posts 1 to provide some structural resistance and cohesion to system 10
  • the posts 14 are typically installed substantially equidistant from each other, especially in an orchard where trees have been planted intentionally also substantially equidistant from each other.
  • the posts 14 are provided at their lower portions with channels 27 for receiving bottom edges 29 of the shield 16.
  • the receivers 27 may be provided with locks 25 to secure the shield 16 in place and seal against the bottom tray 18.
  • the system 10 is provided with a deploying mechanism that is either manual or motorized with a motor 26 located on one of the posts 14, preferably substantially at midpoint along the row of posts 14 so that the motor 26 can drive shafts 28 extending in opposite directions towards each end of the row of posts 14.
  • Shield 16 is attached to the shafts 28 either at the shield top edge or at the shield bottom edges 29.
  • the shield 16 may be attached to the shafts 28 by its bottom edges 29 via cables 31 .
  • Activating the motor 26 in one direction rolls up the cables 31 around the shafts 28 so that the bottom edges 29 are pulled up and the shield 16 bundles at the upper portion of the posts 14.
  • motor 28 is activated in the opposite direction so the shafts unroll the cables 31 , thereby lowering the bottom edges 29.
  • the bottom edges 29 of the shield 16 are each provided with a longitudinal tube 33.
  • This tube 33 adds weight to the bottom edge 29 of the shield 16 to pull downwardly by gravity the bottom edges 29 of the shield 16 during deployment of the shield 16.
  • the shield 16 is made at least partially of a netting material typically used in the construction of nets, such as meshed material, or screen, that lets rain through, but keeps insects out.
  • the shield 16 may also use material that is impermeable to rain, for example, at its top portion.
  • This shield design is used to reduce humidity within an enclosed volume around the canopy of the trees 12 (or branches of plants) defined by the shield 16, the bottom tray 18 and end covers 40 located at each extremity of the system 10. Reducing the humidity in this enclosed helps prevent mushrooms propagation on leaves.
  • shield 16 may use a combination of impermeable and permeable materials depending on environmental conditions and on intended purposes.
  • the end covers 40 may be made of the same material as the shield 16.
  • At least some of the posts 14 are provided with supports 30, such as bearings, bushings, sliders or other mechanical adequate equivalent for rotatably and slidingly supporting the shafts 28.
  • Shafts 28 are mounted to be only vertically supported and longitudinally floating (slidable) in the supports 30. This advantageously allows some variation in the distance between adjacent posts 14, often caused by ground movement, for example during thaw in spring, does not induce a load in the shafts 28.
  • FIG. 4 is now concurrently referred to.
  • the left and right lateral guides 24 and a ridge guide 52 form three vertices of a virtual isosceles triangle 34.
  • the ridge guide 52 being higher than the two lateral guides 24, represents the summit of the virtual isosceles triangle 34.
  • the angles a of the virtual isosceles triangle located at the vertices of the lateral guides 24 preferably measure at least 40 degrees.
  • using cables 31 to retract and deploy the shield 16 allows placing the shafts 28 at an intermediate position within the triangle 34. By adjusting the position of the ridge guide 52, the angles a may be easily adjusted.
  • the ridge guide 52 may be a wire or a tube.
  • the cables 31 may be routed between the shafts 28 and the longitudinal tubes 33 at the bottom edges 29 through pulleys 54 attached proximate, or to, the ridge guide 52.

Abstract

L'invention concerne un système et un procédé de protection d'une plantation en rangée unique contre des insectes. Les plantes peuvent être des arbres, des arbustes ou des vignes. Le système comprend une rangée de poteaux alignés avec la rangée unique de plantes, un écran s'étendant sur une longueur de la rangée de poteaux, un plateau au-dessous des branches des plantes et deux couvercles d'extrémité. Le plateau inférieur, qui s'étend le long de la longueur de la rangée de plantes, comporte des ouvertures pour s'adapter et se sceller étroitement contre les poteaux et les tiges des plantes. Dans une position déployée, l'écran peut être actionné pour venir en prise avec le plateau inférieur pour assurer l'étanchéité contre celui-ci. Les deux couvercles d'extrémités assurent l'étanchéité contre l'écran et contre le plateau, protégeant ainsi les branches des plantes contre les insectes. L'écran peut utiliser un matériau en filet.
