Definitions

  • the invention relates to a device and a method for the netting of trees as featured in the preamble to claim 1 and claim 13.
  • Such devices comprise a supply opening that is configured at the end of a funnel-shape tube being, at its opposite end, connected to a cylindrical tube.
  • the device is positioned horizontally, the tree to be netted being pressed with its cut-off end first into the wide end of the funnel-shaped tube and continuing into the cylindrical tube.
  • a gripper claw or hook can be provided for pulling the tree through the cylindrical tube.
  • a sleeving or hose-shaped net has been pushed over the cylindrical tube, the end of the net being suspended beyond the end thereof.
  • the free end of the net is secured to the tree—either by a knot being tied at the end of the net or by the net being secured relative to the tree in any other manner, and the net is subsequently pulled off the cylindrical tube as the tree is pulled there through.
  • the net is cut off, which is preferably performed manually—and the tree is netted.
  • this device is associated with the drawback that—when used for large scale operation where a large number of trees are netted—three persons are usually required to complete the operation: one for feeding trees to the device, one for cutting off the sleeving, and one for discharging the netted trees from the device.
  • this prior art device is fairly long, partly due to the protracted length of the funnel-shaped tube and the cylindrical tube, and partly because the trees to be netted are pulled all the way through the funnel-shaped tube by means of a pulling device.
  • the friction that occurs between the tree to be netted and the inside of the cylindrical tube is also of a significant magnitude, in particular when the cylindrical tube is long as is the case with the prior art device.
  • the dependent claims feature particularly preferred embodiments that further improve the device according to the invention.
  • FIG. 1 is an explanatory sketch showing a device for the netting of trees according to the invention
  • FIG. 2 shows an explanatory cross section of the device
  • FIG. 3 shows a tree partially pulled through the device shown in FIGS. 1 and 2.
  • a preferred explanatory embodiment of a device for the netting of trees in accordance with the invention comprises a supply opening 1 provided, in the embodiment shown, in a plate 2 in the form of a circular opening having an inclined edge 3 , whereby the supply opening 1 is caused to have a larger diameter on the forwardly oriented side of the plate 2 than on the opposite side.
  • a netting tube 4 is provided that consists of a circular tube having an internal diameter that corresponds essentially to the smallest diameter of the supply opening 1 , ie corresponds to the dimension of the supply opening 1 in the plate 2 at the side that faces towards the netting tube 4 .
  • the netting tube 4 is provided with a sleeve- or hose-shaped net 5 that is compressed in the longitudinal direction, as shown, which means that—as a starting point—it fills the netting tube 4 along the entire longitudinal expanse thereof. Such compression of the net 5 enables positioning of many metres of net sleeving 5 on the comparatively short netting tube 4 .
  • the netting tube 4 is provided with a flange 6 that constitutes an end stop for the net 5 , whereby it is kept on the netting tube 4 .
  • the end stop of the net 5 is constituted by the plate 2 with the supply opening 1 , the plate 2 being, however, located a short distance from the netting tube 4 to allow the net 5 to be pulled around the front end 7 of the netting tube 4 , whereby this end of the net 5 can be bent into the netting tube 4 , as shown in FIG. 2.
  • the distance between the front edge 7 of the netting tube 4 and the plate 2 has exactly such expanse that there is room for the net 5 to be located there between. If a commonly used net 5 of nylon is used, the distance between the netting tube 4 and the plate 2 needs only be about 1 mm.
  • the netting tube 4 is, at the front edge 7 provided with an outwardly protruding bead 8 that causes the net 5 to be stretched when it is pulled across the bead 8 .
  • an outwardly protruding bead 8 that causes the net 5 to be stretched when it is pulled across the bead 8 .
  • a pull device for pulling a tree to be netted through the supply opening 1 and the netting tube 4 .
  • the pulling device comprises two gripper claws 9 , each of which being securely attached to a rotatable tube 10 via a lever 11 .
  • a pull bar 12 is pivotally mounted that is, at its opposite end, connected to a hydraulic cylinder 13 via a connector element 14 .
  • this construction causes the gripper claws 9 to first be pulled towards each other, optionally around the cut-off end of a tree, following which the entire pull device will be displaced to the right in FIGS. 1 and 2.
  • a cutter device 15 is provided immediately after the netting tube 4 , said cutter device 15 comprising, in the embodiment shown, two rotatably mounted and partially overlapping cutter blades 16 that efficiently cut the net 5 off when they are conveyed downwards through an empty net 5 after a tree has been pulled through the device. Underneath the cutter blades 16 , two conical rollers 17 , 18 are mounted that have between them a narrow slot.
  • rollers 17 , 18 rest against the netted tree as it leaves the netting tube 4 , and the moment the top of the tree has travelled past the rollers and there remains only net 5 , the cutter device drops downwards due to its weight, the net 5 penetrating upwards between the rollers 17 and 18 , and the cutter blades 16 cutting off the net 5 .
  • the cutter device is rotatably mounted about an axis parallel with the longitudinal axis of the netting tube, which is not, however, shown in further detail.
  • a cutter device configured in this manner is of course not restricted to use in connection with a device for the netting of trees according to the present invention, but it may just as well be useful in connection with other devices for the netting of trees.
  • a conveyor belt 19 is provided that is able to transport the netted tree away from the netting device as such.
  • the device for the netting of trees is adjusted as shown in FIG. 2, ie with the front end of the net 5 within the netting tube 4 and the gripper jaws 9 also within the netting tube 4 , they being preferably located at the inner face thereof.
  • the cut-off end of a tree to be netted is now conveyed into the supply opening 1 and further into the netting tube 4 , where it is enclosed by the net 5 , whose end is loosely suspended within the netting tube 4 .
  • the hydraulic cylinder 13 is activated whereby the gripper jaws 9 are caused to engage with the cut-off end of the tree as explained above.
  • the pull device is able to pull the entire tree through the netting tube 4 , but preferably the pull device stops when the thickest portion of the tree has been pulled through, since it is possible to pull the remainder of the tree through by use of less force.
  • the device according to the invention can be made significantly shorter than the known devices where a pull device pulls the entire tree through the funnel-shaped tube and the cylindrical tube.
  • the rate of the conveyor belt 19 corresponds to the rate of the pull device whereby the conveyor belt 19 cooperates with the pull device when the tree drops thereon.
  • the conveyor belt 19 may be configured such that it runs at an increased rate, eg 2.5 times faster, when the pull device has let go of the cut-off end of the tree and is moved back to its starting position, whereby the tree is removed from the netting tube 4 more quickly.
  • the netting tube 4 is, in the preferred embodiment, provided, at the front edge 7 , with an outwardly protruding bead 8 that causes the net 5 to be stretched when pulled across the bead 8 .
  • the bead 8 has an outer diameter that corresponds essentially to the maximum diameter of the net sleeving 5 , whereby additional resistance against the net 5 being pulled over the edge 7 is generated, with the result that the net 5 within the netting tube 4 is further tightened in the longitudinal direction when a tree along with the net 5 is pulled through the netting tube 4 .
  • tight netting of the tree is accomplished.
  • the shown and described device for the netting of trees is provided with a hydraulic pull device for pulling trees through the device.
  • a hydraulic pull device for pulling trees through the device.
  • other kinds of pull devices eg a mechanical device, or to altogether omit same and pull the trees through the device manually.
  • the shown and described device can be constructed as a separate unit or it may be constructed for mounting on eg a tractor or other forestry machinery. Likewise, it may be combined with other units, such as eg a palleting unit to which the conveyor belt may convey the netted trees.
  • the netting tube can be configured as a replaceable cassette, which means that it can readily be replaced when the net on the first netting tube has been used up.
  • a winding device can be mounted instead of the netting tube, whereby the same device can also be used for tying trees.
