Definitions

  • the present invention relates to a method and an apparatus for feeding twigs one by one from a bundle of energy forest sprouts, for the further handling or treatment thereof.
  • the object of the present invention is to provide a method and an apparatus for achieving an efficient, labour-saving feeding of energy forest sprouts one by one into a subsequent handling or treatment position, preferably in a planting apparatus.
  • Fig. 1 is a sideview of an embodiment of a feeding apparatus according to the invention
  • Fig. 2 is a rear view of the feeding apparatus according to Fig. 1
  • Fig. 3 is a schematical view from above of the chute of the feeding apparatus according to Figs. 1 and 2, with the down-feed housing omitted, but with the positions of the drive belts by the aperture for the downward feeding illustrated,
  • Figs. 4a and 4b are detailed views illustrating a typical embodiment of the drive mechanism for the downward feeding means of the feeding apparatus.
  • Fig. 5 is a schematic illustration of a sprout bundle retainer according to Fig. 1.
  • the feeding apparatus basically consists of a feeding chute 1 and a down-feed housing 2.
  • the feeding chute 1 has a general V-shape in cross-section, where the angle between the legs of the V-shape is not critical but may be modified in view of the specific application.
  • a bundle of energy forest sprouts are positioned standing upright in the chute 1, whereby they are held together in the bundle adjacent their upper ends, by means of a support ring 4 which, for the insertion of the bundle 3 of sprouts is open at the back, at 4a, and which at the back is provided with two rods or tines 4b attached at each end of the ring 4 and arranged such that they cross each other.
  • the rods or tines are resilient in such a manner that they are deflected when a bundle of sprouts is inserted but prevent the sprouts from falling out backwardly after having been inserted.
  • the chute 1 is in itself also provided with a stop la at the rear end thereof, in order to prevent the root ends of the sprouts from sliding out rear- wardly from the chute 1.
  • the chute 1 At its forward end the chute 1 is likewise provided with a stop lb in order to prevent the root ends of the sprouts 3 from sliding too far ahead, but this forward stop lb is not extended at a level with the forward end of the chute 1 but is curved outwardly so that it generally has the shape of a hopper split in half along its longitudinal centre plane with the hopper-shape or funnel-shape directed downwardly towards the down-feed housing 2.
  • the chute 1 At a position straight above the down-feed housing 2, in the area of the apex of the V-shape and substantially at the transition area between the end of the chute 1 and the funnel-shaped forward stop lb, the chute 1 is also provided with a down-feed aperture
  • the down-feed aperture 5 is preferably circular and should be dimensioned such that it permits feeding- down the root end of the energy forest sprouts therethrough, whilst simultaneously preventing the feeding-down of two sprouts simultaneously. Since the energy forest sprouts have a consider ⁇ ably smaller diameter at the top end than in the root end and since the root end of a subsequent sprout must not be fed down before the top end of the previous sprout has left the down-feed aperture, the aperture 5 must be dimensioned accordingly, i.e. the diameter of the aperture 5 may only slightly exceed the maximum expected diameter of the root end.
  • a sprout guide 6 is also provided above the down-feed aperture 5, and the purpose of this guide 6 is to make sure that the sprout 3 which is being fed down is maintained substantially centrally in the down-feed aperture 5 also during the final phase of its downward feeding, i.e. when the thin top end is fed down.
  • the sprout guide 6 is also provided above the down-feed aperture 5, and the purpose of this guide 6 is to make sure that the sprout 3 which is being fed down is maintained substantially centrally in the down-feed aperture 5 also during the final phase of its downward feeding, i.e. when the thin top end is fed down.
  • the sprout guide 6 is also provided above the down-feed aperture 5, and the purpose of this guide 6 is to make sure that the sprout 3 which is being fed down is maintained substantially centrally in the down-feed aperture 5 also during the final phase of its downward feeding, i.e. when the thin top end is fed down.
  • the sprout guide 6 is also provided above the down-feed aperture 5, and the purpose of this guide 6 is to make sure that the sprout 3 which is being fed down is maintained substantially
  • Fig. 1 illustrates an example of a suitable support and adjustment mechanism 8 for stabilizing the chute 1 and for simultaneously permitting a stepless adjustment of the angle of inclination.
  • This mechanism 8 consists of two telescopically displaceable portions 8a, 8b which at their free ends are pivotally connected to the down-feed housing 2 and the chute 1, respectively and which may be locked relative to each other by means of a stop screw 9.
  • the down-feed housing 2 is in itself formed by a pair of parallel sidewalls 2a, 2b positioned at a mutual distance from each other and firmly connected to each other by means of a suitable number of transversal connections 2c of which only one is visible in Fig. 1.
  • the pins 11 of four pulleys 12 are rotatably journalled in elongated holes 10 in the sidewalls 2a, 2b of the down-feed housing 2, in such a manner that the pulleys 12 run between the sidewalls 2a, 2b.
  • Two of the pulleys are provided opposite each other, at a distance from each other at the upper end of the down-feed housing 2 and two of them are correspondingly provided at the lower end of the down-feed housing 2.
  • a drive belt 13 travels around each pair consisting of an upper and a lower pulley 12.
  • the drive belts 13 are driven in opposite directions in such a way that between their inner stretches they form a down-feed shaft through which they feed down the sprouts 3 engaged by the drive belts 13 immediately below the down-feed aperture 5 of the chute 1.
  • the belts 13 are provided with a serrated or toothed surface (indicated in Figs. 4a and 4b) in order to safely grip the sprouts 3 received therebetween and to securely move them downwardly.
  • the pins 11 of the upper and lower pulleys 12 respectively which pins are slidably journalled in the elongated holes 10, are connected to each other by means of a spring strap 14 tending to bring the pulleys 12 together as much as possible - down to a distance corresponding to a minimum sprout diameter - but permitting the pulleys 12 to be brought apart from each other against a force at larger sprout diameters.
  • the drive belts 13 will at each instance securely grip the sprouts 3 at one place to securely feed down the sprouts 3.
  • a drive mechanism for the drive belts 13 will now be described more closely.
  • the invention is in no way restricted to this embodiment of the drive mechanism and that, depending upon the actual application, the drive mechanism may be designed in several other ways obvious to a man skilled in the art, for adaption to the specific situa ⁇ tion or application.
  • the described embodiment of the drive mechanism is adapted to be connected to the drive apparatus of the planting apparatus described in the above-mentioned Swedish patent application No. 8904035-6 for obtaining a synchronized down-feed of the full shoot with the cutting and planting move ⁇ ment of the planting apparatus.
  • the drive mechanisms for the drive belts 13, illustrated in the drawings are adapted to the planting apparatus according to the last-mentioned Swedish patent speci ⁇ fication, and in Figs. 4a and 4b the connection is illustrated by means of the pull rod 15 illustrated only in part (deleted from Fig. 1 and only partly illustrated in Fig. 2).
  • the pull rod is assumed to perform upwardly and downwardly directed movements in accordance with the drawn arrow, said upwardly and downwardly directed movements corresponding to a feeding of energy forest sprouts 3 with a length corresponding to a normal cutting length, whereby this movement is taken from and automatically obtained with a correct length through the displacement movement performed in said known planting apparatus for the purpose of cutting cuttings to the correct length.
  • a drive mechanism 16 is provided for each of the drive belts 13, but since said drive mechanisms are identical only one will be described and illustrated in Figs. 4a and 4b.
  • the pull rod 15 is pivotally connected to a clamping piece 17 which in turn is pivotally supported on a pin 18 mounted on a flange 19a protruding from a counterpiece 19.
  • the clamping piece 17 and the counterpiece 19 are provided such that from each side they straddle the drive belt 13.
  • each step corresponds to the feeding-down of the sprout 3 inserted therebetween with a distance correspon ⁇ ding to the length of a cutting.
  • sliding guides 12 of a suitable material are provided between the side edges 2a and 2b of the down-feed housing 2, immediately behind the respective counterpiece 19, and having a length corresponding to the drive movement. The rear side of the counterpiece 19 will contact and will be guided by this sliding guide 21, especially during the upwardly directed feeding movement.
  • a bundle of such sprouts are inserted from behind into the support ring 4 by pushing aside the resilient rods 4b.
  • the sprouts are then positioned with their root end resting in the chute 1 adjacent its rear end.
  • the sprouts 3 will, during their advancement towards the front end of the chute 1, find their way down towards the bottom of the chute and thereby automatically be aligned in a row resting against the bottom of the chute.
  • the movement of the root end of the sprouts 3 towards the forward end of the chute 1 is achieved partly by swinging the chute into a suitable angle of inclination relative to the horisontal, but depending upon the application the forward movement may have to be supported by a vibrating or shaking movement applied to the chute either by a drive means not illustrated in the drawings and provided in connection with the feeding apparatus or, such as by the application for which the embodiment illustrated in the drawings is intended, by the vibra ⁇ tion generated by the planting apparatus during its operation.
  • the support ring 4 is provided at such a distance above the chute 1 that the sprouts 3a are remained therein during their entire movement towards the forward end of the chute 1.
  • the root end falls down through the aperture and is engaged by the drive belts 3 provided immediately below the aperture, between the belts.
  • the funnel-shape of the forward stop lb serves to provide space for the root end of the sprout 3 in the case where this is bent as a bandy stick, which is common.
  • the drive belts 3 When the drive belts 3 are activated they grip the root end of the sprout having fallen down through the down-feed aperture 5 and feed this sprout into the down-feed housing 2, between the drive belts 3, preferably stepwise with the predetermined length of a cutting to be planted. After a certain down-feed the sprout 3 is released from the support ring 4 and will then be maintained substantially centrally between the drive belts 3 by the sprout support 6. Thereby, and by the dimensioning of the down-feed aperture 5 the sprout 3 being fed down will prevent a new sprout from falling down through the down-feed aperture 5 until the preceding sprout has left the down-feed aperture completely unblocked, whereupon the next sprout is fed down in the same manner.
