Definitions

  • the present invention relates to a device for processing cut tree trunks that need to be protected from mold, insects, and all kinds of parasites, whether of plant or animal origin.
  • this type of treatment should not be done by immersion from the surface lateral device of the trunks, but well from one of its ends so as to reach the heart of these and then gradually provoke the longitudinal penetration of the treatment solution.
  • the migration of the treatment solution can therefore be easily introduced into the trunk and drive out the sap it contains by gradually replacing with the treatment solution.
  • the present invention therefore aims not only to remedy the first drawbacks known in the prior art but, by in addition, to perfect the idea of principle which has just been cited.
  • said injection means consist of a bell capable of covering one of the frontal ends of the trunk to be treated and fitted with sealing means provided between the trunk and the bell.
  • said means injection device of the invention are constituted by a chamber sealed compression between, on the one hand, said sealing means and consequently the end of the trunk, and on the other hand, the internal face of the bell through which the treatment solution is brought for injection under pressure in the trunk from the entire surface of its end frontal, for impregnation to the heart and progressive in the direction longitudinal.
  • said injection means constitute a sealed compression between said sealing means on the one hand, and consequently the end of the trunk, and on the other hand the internal face of the bell through which the treatment solution is brought for injection under pressure in the trunk from the entire surface of its end frontal, for impregnation to the heart and progressive in the direction longitudinal.
  • the processing device cut tree trunks 2 by impregnating the fibers with a solution of appropriate treatment, includes injection means I, under pressure, longitudinally to the trunk 2, from one of its front ends 2A, 2A '
  • said injection means I consist of by a bell 1 capable of styling, in particular, simultaneously one of the ends frontal 2A, 2'A of the trunk 2 'to be treated as well as its lateral peripheral surface adjacent 2B, 2'B.
  • the bell 1 is equipped with sealing means 3, 3A, 3B) provided between the trunk 2, 2 'and the bell 1.
  • the half trunk 2 represents a trunk of small diameter while the half trunk 2 'represents a half trunk of large diameter.
  • Their lateral surface 2B, 2'B and their surface frontal 2A and 2'A represent respectively the lateral and frontal surfaces half trunk 2 and half trunk 2 '.
  • a trunk 2 having a lateral surface 2B and an end surface front 2A.
  • the bell 1 covers the whole from the end 2A of the trunk 2 via the sealing means 3 interposed concentrically between the outer peripheral surface 2B of the trunk 2 and the internal peripheral surface 1A of the bell 1.
  • the injection means I constitute a sealed compression chamber 4 between said means on the one hand sealing 3, and consequently the end 2A of the trunk 2, and on the other hand the internal face 1A of the bell 1 through which the solution of treatment, in particular, via a tube 5, in order to be injected under pressure into the trunk 2 from the entire surface of its front end 2A, for a deep and progressive impregnation in the longitudinal direction L, in particular, at a speed as a function of pressure injection.
  • the bell 1 is provided for non-deformable. As developed below, it is thus, in particular, metallic.
  • said bell 1 may also be provided as deformable. It is made up of example, of an elastic sleeve 41, in particular of rubber, and of a canvas sleeve 42, capable of defining its maximum volume. After having been subject to the trunk on the lateral peripheral surface 2B, 2'B of the latter, it is then swollen during the injection of the treatment solution.
  • the device according to the invention is optionally provided with means 43 spacing of the latter.
  • Said spacing means 43 include, in particular, coupling means 44, regularly spaced on the circumference of the mouth of said deformable bell 1, and means 45 simultaneous radial displacement of said coupling means 44.
  • Said coupling means 44 consist, for example, of plates 46, located on either side of the sleeves 41, 42 and connected between them by a screw 47 so as to pinch the latter.
  • Said displacement means 45 are constituted, by example, of a plurality of cables 48, subject to said coupling means 44. Said cables 48 are also guided radially by angles 49.
  • said cables 48 are, for example, able to be tensioned simultaneously.
  • they are, in particular, connected to an attachment point 50 commons sliding along a worm 51 in a maneuver nut 52.
  • a ring 53 may be provided to support said angles. 49 and said maneuvering nut 52, said ring 53 can also be used, optionally, to guide said cables 48 between these elements so as to ease their tension.
  • said bell 1 is optionally provided with a purge 30 allowing the evacuation of air during the injection of the treatment solution.
  • the sealing means 3 are essentially constituted, for example, by a air bag 3 arranged concentrically on the inner surface device 1A of the bell 1 near its mouth and susceptible to enclose, by expansion, the lateral peripheral surface 2B of the end of the trunk 2.
  • the O-ring 3A is capable of cooperating with at least one elastic and crown-shaped 3B midsole cuff, taking place concentrically between said cushion 3A and the lateral peripheral surface 2B end of the trunk 2, when the latter is of a diameter less than that of the O-ring 3A when fully inflated.
  • the O-ring inflatable 3A is capable of cooperating with a plurality of cuffs concentric dividers 3B, of identical shape, making them nestable one inside the other, their dimensions progressing at a step constant from basic inside and outside diameters corresponding to smallest diameter of trunks 2 admitted for treatment.
  • the bell 1 which is metallic, will have a diameter of 570 mm receiving an inflatable O-ring whose outside diameter in contact with the bell is of a diameter identical to this while its internal diameter can be variable up to 520 mm.
  • cuffs interlayer elastic bands have a pitch of 20 mm, i.e.: a set of 300/320 - 320/340 - 340/360 - 360/380 - 380/400 - 400/420 - cuffs 420/440 - 440/460 - 460/480 - 480/500 - 500/520.
  • trunks ranging from 300 mm to 570 mm if we also count the possibilities offered by the air bag, by itself, depending on whether it is inflated or deflated.
  • the sealing means 3 consist of said sleeves 41, 42 defining the deformable bell 1 themselves, said deformable bell 1 being secured on the trunk 2 by one or more clamps 54.
  • said elastic sleeves 41 and canvas 42 are, for example, related to their opposite end to that cooperating with the trunk, on a base 55, provided said supply 5 and said purge 30. Maintaining them on said base 55 is provided by one or more clamps 56.
  • the bell 1 is arranged horizontally on an equally horizontal support 6, by through a hydraulic cylinder 7 adjustable in height along H and itself mounted on rollers 8 to allow longitudinal adjustment along L, so to be able to present the mouth 1C of the bell 1 on the peripheral surface lateral 2B of a trunk 2, according to these two parameters H and L, said trunk 2 being previously immobilized in a horizontal position and in the XX 'axis of the bell on the same support 6 as this one.
  • rollers 8 of the hydraulic cylinder 7 supporting the bell 1 rest on rails 9 integral with the horizontal support 6.
  • the trunk 2 to treated is retained in place on the support 6, during the injection operation, by lateral stops 10 located on either side, and by a blocking stop longitudinal 11 located at the end 20 of the trunk 2, opposite to that opposite 2B introduced in bell 1 for the initialization of the treatment.
  • a plurality of bells, in occurrence 2 is integrated into the device, so as to process simultaneously a corresponding number of trunks. It could also be three or more bells arranged in a revolver turret.
  • the mobile trailer 17 has four stabilizing jacks 20 located at its four end angles and a hitch 21 allowing its connection to a towing vehicle.
  • the or said bells 1, provided for non-deformable are left without support.
  • the trunks 2 are then supported, for example, independently of said bells 1 by wedges 32, in particular consisting of tree trunks.
  • a mobile container 33 is possibly provided for the transport, among others, of one or more treatment solution tanks, a generator, a compressor, a control and regulation cabinet, a set of bells 1 and their sealing sleeve 3 and / or a set of hoses 34 of different lengths, able to be connected to said supply valves 5.
