Definitions

  • the present invention regards a system for covering crops, comprising a plurality of plastic strips or sheets, suspended over said crops, provided with means for enabling partial gathering of said plastic sheets in order to air said crops.
  • Crops, in particular grapevines, are usually protected from hail and excessive solar radiation with covers constituted by sheets made of transparent pi asti c materi al .
  • the supporting structure of said sheets is constituted by a plurality of posts driven into the ground and aligned along the rows, said posts keeping a rope pulled over the top of them.
  • the sheets which are in the form of strips some metres wide and approximately as long as the row that they cover, are rested in midline on said pulled rope.
  • the strips of the parallel rows are then joined together along the edges with laces and clamps so as to form a continuous cover.
  • the width of the sheets is chosen with a certain excess so as to create a series of sloping stretches that favour draining of rainwater.
  • the edges are hooked with elastic ropes to hooks driven into the ground to prevent even minor gusts of wind from being sufficient to raise the sheets and cause them to vibrate.
  • this operation is carried out by unlacing the sheets so as to separate the strips and gather said sheets, hooking them to the respective posts.
  • the cover is not eliminated completely, but wide openings are formed in positions corresponding to the posts, said openings being sufficient to guarantee air change.
  • the operation of separation of the strips does not present particular problems, it being sufficient to walk along the edges of the strips and unhook the connecting laces.
  • the gathering operation instead, is not equally convenient, in the first place because the ridge ropes are rather high from the ground and are not easily reachable by persons of small stature, in the second place because these ridge lines are in positions corresponding to the crops so that it is far from convenient also to approach them, and finally because the operation of gathering of the sheet is in any case laborious and then requires tying for the sheet to remain gathered up.
  • a cover system has been proposed of the type comprising a plurality of sheets or nettings made of plastic material, in the form of parallel strips joined together or set up against one another along the edges and supported by ropes stretched horizontally along the rows, said ropes being supported over the rows by purposely provided posts.
  • the system according to the invention is characterized in that it envisages means designed to retract in a transverse direction said strips made of transparent plastic material towards their midline in such a way that wide spaces are opened between the strips for airing the underlying crops.
  • These means designed to retract the strips comprise a flexible cord that winds round the strips themselves, said flexible cord forming a loop at each of the posts in such a way that by closing the loop, the cover is gathered up, retracting towards the midline of the strip.
  • EP 2368421 and EP 271207 are systems for covering rows to protect them from hail or from adverse weather conditions, said systems being provided with means for opening the coverings for the entire length of the row, but these patents regard plane covering surfaces, which do not convey rainwater, hail, etc. to the sides of the rows and moreover envisage transverse ropes for supporting the cover, which are not present or necessary in the technical solution forming the subject of the present invention.
  • Figure 1 shows the system for covering crops in the case where the sheets are completely stretched out over the rows, in which each row has a winch with self-blocking gear, which can be operated via a crank on one of the end posts, whilst on the other end post a rear winch is preferably provided for recall of the rope with a rewinding spring;
  • Figure 2 shows the covering sheets of Figure 1 in the closed configuration, i.e., gathered over the supporting posts of the row;
  • Figure 3 corresponding to Figure 1, shows a variant of the invention in which all the winches on the end posts (or sets thereof) are connected and operated synchronously via a tube that is made to turn by a purposely provided electric motor of adequate power;
  • Figure 4 shows an enlarged detail of the invention, visible in which is the system for fixing each return spring for stretching out the sheets again, via a purposely provided ring that is hooked to the edge of the respective sheet as well as to the loop that is used for gathering the sheet at each post when it is desired to uncover the row.
  • a sheet 4 preferably made of transparent plastic material (HDPE, Mater-Bi or the like), said sheet being in the form of strips some metres wide and substantially as long as the row.
  • Covering of the crop is obtained by driving a number of rows of posts 2 into the ground, said rows being appropriately set at a distance apart in such a way that when these sheets 4 are stretched out, a continuous cover is formed.
  • the arched rods 3 are of a length such that the side edge of the sheet 4 of one row is adjacent to or at the side edge of the sheet 4 of the contiguous row. According to the prior art, it is also possible to envisage purposely provided laces and clamps for connecting together the side edges of the sheets 4 set side by side.
  • post covers 5 appropriately shaped so as to be fitted on the top of said posts 2.
  • the covering is hence constituted by a series of parallel sheets 4 supported in a longitudinal direction by a plurality of pulled ropes 6 and in a transverse direction by said arched rods 3.
  • a flexible cord is provided set around the sheet 4 so as to form a respective loop 7, in which said loop lies in a plane perpendicular to the pulled rope 6.
  • the ends 7a-7b of said loop 7 pass through a purposely provided hole or side ring set in the proximity of the post cover 5 in such a way that, by pulling said ends 7a-7b, the loop 7 is tightened around the sheet, gathering it up towards the midline, thus opening up wide spaces to enable airing of the crops .
  • the present invention envisages that, for each row, the ends 7a-7b of each loop 7 are firmly fixed to a control rope 8, which is purposely arranged horizontally throughout the length of the row.
  • two lateral elastic means M such as two tension springs, designed to widen the loop, and hence stretch out the sheet completely, when the control rope 8 is released and consequently the ends 7a-7b of the loop return into their initial position.
  • these lateral springs M are fixed to the edge of the sheet 4 and preferably to the corresponding loop 7 via a purposely provided ring 15 (see Figure 4), said ring being hooked to the loop 7 and s multaneously fixed to the sheet 4 via a hole purposely provided in the sheet itself, in the proximity of its side edge.
  • end posts 9 are provided, one with a winch 10 with self-blocking gear which can be operated via a crank, and the other (optional) with a rear winch 11 for recall of the rope 8 with a rewinding spring.
  • the ends 7a-7b of the loop 7 run in a winch 14 with clamping mechanism, appropriately fixed to each post 2, substantially at the height at which the horizontal rope 8 is located.
  • Said front winch 10 in order to pull/loosen the rope 8, is preferably operated manually via a crank with a pawl -and- ratchet mechanism of a known type.
  • the front winch 10 and the rear winch 11 are preferably mounted on purposely provided end posts 9 appropriately inclined and firmly anchored to the ground to be able to withstand the forces that develop during actuation of the rope 8 to open/close the cover 4.
  • a variant of the invention envisages that all the winches 10 (or sets thereof) are connected and operated synchronously via a tube 13 that is made to turn by a purposely provided electric motor 12 of adequate power.
  • said motor 12 it is advantageously possible to operate said motor 12 directly to control s multaneously open ng/clos ng of the covering sheets 4 of a series of rows, without it being necessary to intervene on the individual row to gather or stretch out the corresponding sheet 4.
