Description
10~3~1Z
Present invention is related to a flax decorticator more specifically the present invention relates to a mobile decorticator for collecting flax straw in the field decorticating the flax straw, separating bast and dross fibres, leaving the dross fibres in the field and packaging the bast fibres.
'DESCRIPTION OF THE PRIOR ART
Various equipment has been proposed for use in ' decorticating flax and also has been proposed to utilize equipment in the field. Such equipment is shown for example in U.S. patents 2,983,965 and 3,064,315 issued May 15, 1961 and November 20, 1962 respectively to Schneider Jr. The equipment disclosed in these two patents uses a hammer mill and carries the flax through the hammer mill in an air stream with the dross fibxes being driven through the cage of the hammer mill so that ~ the hammer mill performs two functions, namely, that of ,, decortication and of separation. While this equipment ! was designed to be mobile, it was found to be too heavy to be utilized by passing through the field to harvest the flax straw and the flax straw had to be transported to a fixed location for processing. This device also required considerable horse power and c,ould not be driven, for example, from a power take-off on a conven-tional tractor.
' Subsequently a more efficient decorticator was described in U.S. patent 3,872,545 issued Narch 25, 1975 to Altassar. This device uses a disc rotating in close proximity to housing with the disc and the housing being provided with co-operating pins mounted at specific angles so that the flax could be decorticated using relatively little power. However, this device while .
--' 109341Z
being effective as a decorticator, provided no separa-tion for the bast and dross after decortication.
BRIEF DESCRIPTION OF THE PRESENT INVENTION
It is the object of the present invention to provide a mobile light-weight, low horse power, flax decorticator and adapted to travel through the field and collect the flax, decorticate same separate the bast from the dross and package the bast in suitable form for transport.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Like reference numerals indicate like parts throughout the various views.
Figures 1 and 2 schematically illustrate the operation and arrangement of equipment comprising the present invention. The equipment includes a pick-up device 10 which may be a rake type pick-up convention-ally used to pick-up swaths of grain in the field.
Normally the flax will have been harvested and the flax straw left in rows or swaths in the field. In any event, the pick-up 10 collects flax straw from the row or swaths of flax straw schematically illustrated 12 and passes it onto the ramp 14 which has a pair of substan-- `
lOg341Z
tially vertical belt conveyers 16 and 18 positioned one on each side thereof. Preferably each of these convey-ers is pivotedably mounted adjacent the pick-up 10 and has its end remote from the pick-up 10 movable toward and away fro~ and biased toward the other of said conveyers via spring means schematically indicated at 15 (Figure 2). In the illustrated arrangement the arrows 20 indicates such movement for the conveyers 16 and 18.
This movement meters the flow of straw and ensures that - 10 the flax straw is gripped and fed by the belt conveyers 16 and 18 into a shredder generally indicated at 22.
The conveyers 16 and 18 are driven by suitable hydraulic motors indicated at 21 (Figure 2).
The conveyer 16 on the side of the shredder 22 leading in the direction of rotation is provided with a deflection plate 19 which moves with the free end of the conveyer to open and close the mouth ~ the housing of the shredder so that the material as it is being shred-ded is retained within the shredder and is directed to the inlet conduit.
The shredder 22 is provided by a housing 24 enclosing a rotating drum 26 formed by a plurality of substantially triangular discs or plates 28 stacked one on top of the other with the points of the triangles slightly offset one relative to the other. The drum 26 is driven by a suitable hydraulic motor 25 in the direction of the arrow 27. The flax straw enters the shredder 22, is engaged by the points of the plates 28 and is projected along an infeed conduit 30 toward the decorticator 32. The shredder 22 functions to prelimi-narily breakdown or cut the flax straw into short 10~341Z
lengths and to accelerate and project the flax into and along the conduit 30 towards the decorticator 32.
The decorticator 32 is substantially the same as the decorticator described in the said U.S. patent 3,872,545 to Altaasar and is composed of a disc 34 rotating within a housing 36. One wall or face 38 of the housing 36 cooperates with the front face 40 of the disc to form between them a working space 42. The faces 38 and 40 are provided with working elements 44 and 46 respectively in the form of pins arranged in consecutive rows in the inter-meshing, over-lapping relationship so that the pins of 46 on the disc do not interfere with the pins 44 on the housing and vice versa as the disc is rotated relative to the housing. The pins 46 on the rotating disc slope away from the face 40 rearwardly relative to the direction of rotation of the disc (see Figure 3), and the pins 46 on the housing slope away from the face 38 forwardly in the direction of rotation, -while the pins 44 and 46 all slope radially outward relative to the axis of rotation of the disc. Thus the pins 44 and 46 all slope radially outward and tangen-tially to facilitate the passage of flax through the decorticator as described more fully in the said United States patent 3,872,545.
It will be noted that the conduit 30 is directed at an angle to the working face 40 and offset from the axis of rotation of the disc 34 so that the flax entering the working space 42 does so at an angle directing the material with a momentum in the direction radially outward of the disc. To facilitate this radial movement impellers or paddles such as those indicated at 48 are mounted on the rear face of the disc and func-., ~ , tioned to draw air in through the duct 30 and throughthe back wall 50 of the decorticator to help transport the flax toward the decorticator 32 through the inlet duct or conduit 30 and from the decorticator 32, through the exhaust conduit 52 and into the pneumatic cyclone separator 54. The disc 34 is driven by a suitable motor -schematically illustrated at 56.
The cyclone separator 54 has a cylindrical section 58 and a conical section 60 and the conduit 52 provides a tangential inlet adjacent the top or base of ~ the cylindrical section 58. Suitable outlets including 4~ 6/
a base outlet ~J for air and an apex outlet 62 for the bast fibre are provided at opposite longitudinal ends of the cyclone separator 54.
The cyclone separator 54 is not a conventional cyclone separator although it has many features in com-mon with a conventional cyclone separator. As shown in Figure 4 the cyclone separator 54 at its base outlet ~t and a vortex finder 64 which projects into the cyclone separator almost to the bottom of the cylindrical section 58. However, the conical section 60 is provided with, in the illustrated arrangement, a pair of substan-tially axially extending slots 66 and 68 which are covered with screening rod means generally indicated at 70 and 72 respectively. Screening means are mounted from bars 74 and 76 trailing openings 66 and 68 respec-tively in the direction of movement of the material.
The screening means 70 and 72 are each compos-ed of a plurality of round or cylindrical rods about 1/4" diameter on 1/2" centres and each of the bars 74 and 76 has a thickness (projecting in from the conical wall 60) of approximately 1/8 n .
In operation the material first traverses the bars 74 and 76 which tend to deflect material away from the wall then across the openings 66 and 68. The rods 70 and 72 extend substantially in the direction of move-ment of the material and thus do not obstruct movement of the material around the cyclone, however they tend to block the opening to bast fibre while permitting the escape of dross material through the openings 66 and 68.
The openings 66 and 68 are enclosed on the outer surface of the cyclone by a housing generally indicated at 78 (see Figure 5) that provides a passage 80 for the dross material escaping through the outlets 66 and 68 and directs this material down and out of the unit as indicated by the arrow 82 in Figure 4. Thus the dross material leaves the equipment in operation and is thus spread around the field due to the movement of the equipment around the field to pick up the straw and thereby facilitates its functioning as fertilizer.
The preferred arrangement of the present invention as above described incorporates the separator device as a part of a pneumatic cyclone but this is not essential. Other conventional screening means may be used. For example, air may be separated from the decorticated flax using a conventional cyclone and the , dross material separated from the bast using a conven-i tional screening means adapted to make the separation.
However, such arrangements generally significantly increase the weight of the unit and could result in significantly impairing mobility of the equipment.
~^ 5~
Bast material leaves the cyclone 44 through the apex outlet 62 and is introduced into a suitable baling mechanism generally indicated at 84. The baler ~' , ':, ' , . , 1093~1Z
is provided with the conventional reciprocating plunger mechanism 86 to form the bale which is ejected as indicated by the arrow 88 to provide bale 90 that may be transported to the site where it is finally used.
The feed rate of the baler is correlated with the production or feed of bast from the cyclone which will normally require reducing of the speed of the baler piston so that the number of strokes of the piston is fewer than a conventional baler. The flax is not a fodder crop similar to for example alfalfa, and it has been found that the speed of the baler can be slowed down to about 6 or 8 strokes as compared with the strokes of the conventional baler.
The baler 84 preferably will be a wire type baler rather than a conventional cord type baler as it has been found that with the cord type baler difficulty is encountered in producing a tight bale since the spring-back of the bast fibres is not equivalent to the spring-back normally encountered in conventional hay or ; 20 other fodder material normally baled with the equipment.
Each of the elements such as the shredder 22, disc 34 and the conveyers 16 and 18 may be driven by any suitable means such as hydraulic motors. Power requirements of the equipment are relatively small and therefore the power source may be the same as the equipment used to pull the device through the field i.e.
the power take-off from a suitable tractor. In the arrangement shown the power take off from the tractor is used to power the hydraulic pump schematicall~
indicated at 96 in Figure 2 which in turn _ g _ ~09341Z
drives the various hydraulic motors. The baler is also driven from the power take-off while the pick-up 10 is driven by rotation of the wheel 92 by ground engagement and through the drive chain 94 (see figure 2).
The bast rich fraction that is baled generally contains about 60% bast 40 dross as is normally best suited for pulping.
Modification can be made without department from the spirit of the invention as defined in the appended claims, , ~

Normally the flax will have been harvested and the flax straw left in rows or swaths in the field. In any event, the pick-up 10 collects flax straw from the row or swaths of flax straw schematically illustrated 12 and passes it onto the ramp 14 which has a pair of substan-- `

tially vertical belt conveyers 16 and 18 positioned one on each side thereof. Preferably each of these convey-ers is pivotedably mounted adjacent the pick-up 10 and has its end remote from the pick-up 10 movable toward and away fro~ and biased toward the other of said conveyers via spring means schematically indicated at 15 (Figure 2). In the illustrated arrangement the arrows 20 indicates such movement for the conveyers 16 and 18.
This movement meters the flow of straw and ensures that - 10 the flax straw is gripped and fed by the belt conveyers 16 and 18 into a shredder generally indicated at 22.
The conveyers 16 and 18 are driven by suitable hydraulic motors indicated at 21 (Figure 2).
The conveyer 16 on the side of the shredder 22 leading in the direction of rotation is provided with a deflection plate 19 which moves with the free end of the conveyer to open and close the mouth ~ the housing of the shredder so that the material as it is being shred-ded is retained within the shredder and is directed to the inlet conduit.
The shredder 22 is provided by a housing 24 enclosing a rotating drum 26 formed by a plurality of substantially triangular discs or plates 28 stacked one on top of the other with the points of the triangles slightly offset one relative to the other. The drum 26 is driven by a suitable hydraulic motor 25 in the direction of the arrow 27. The flax straw enters the shredder 22, is engaged by the points of the plates 28 and is projected along an infeed conduit 30 toward the decorticator 32. The shredder 22 functions to prelimi-narily breakdown or cut the flax straw into short 10~341Z
lengths and to accelerate and project the flax into and along the conduit 30 towards the decorticator 32.
The decorticator 32 is substantially the same as the decorticator described in the said U.S. patent 3,872,545 to Altaasar and is composed of a disc 34 rotating within a housing 36. One wall or face 38 of the housing 36 cooperates with the front face 40 of the disc to form between them a working space 42. The faces 38 and 40 are provided with working elements 44 and 46 respectively in the form of pins arranged in consecutive rows in the inter-meshing, over-lapping relationship so that the pins of 46 on the disc do not interfere with the pins 44 on the housing and vice versa as the disc is rotated relative to the housing. The pins 46 on the rotating disc slope away from the face 40 rearwardly relative to the direction of rotation of the disc (see Figure 3), and the pins 46 on the housing slope away from the face 38 forwardly in the direction of rotation, -while the pins 44 and 46 all slope radially outward relative to the axis of rotation of the disc. Thus the pins 44 and 46 all slope radially outward and tangen-tially to facilitate the passage of flax through the decorticator as described more fully in the said United States patent 3,872,545.
It will be noted that the conduit 30 is directed at an angle to the working face 40 and offset from the axis of rotation of the disc 34 so that the flax entering the working space 42 does so at an angle directing the material with a momentum in the direction radially outward of the disc. To facilitate this radial movement impellers or paddles such as those indicated at 48 are mounted on the rear face of the disc and func-., ~ , tioned to draw air in through the duct 30 and throughthe back wall 50 of the decorticator to help transport the flax toward the decorticator 32 through the inlet duct or conduit 30 and from the decorticator 32, through the exhaust conduit 52 and into the pneumatic cyclone separator 54. The disc 34 is driven by a suitable motor -schematically illustrated at 56.
The cyclone separator 54 has a cylindrical section 58 and a conical section 60 and the conduit 52 provides a tangential inlet adjacent the top or base of ~ the cylindrical section 58. Suitable outlets including 4~ 6/
a base outlet ~J for air and an apex outlet 62 for the bast fibre are provided at opposite longitudinal ends of the cyclone separator 54.
The cyclone separator 54 is not a conventional cyclone separator although it has many features in com-mon with a conventional cyclone separator. As shown in Figure 4 the cyclone separator 54 at its base outlet ~t and a vortex finder 64 which projects into the cyclone separator almost to the bottom of the cylindrical section 58. However, the conical section 60 is provided with, in the illustrated arrangement, a pair of substan-tially axially extending slots 66 and 68 which are covered with screening rod means generally indicated at 70 and 72 respectively. Screening means are mounted from bars 74 and 76 trailing openings 66 and 68 respec-tively in the direction of movement of the material.
The screening means 70 and 72 are each compos-ed of a plurality of round or cylindrical rods about 1/4" diameter on 1/2" centres and each of the bars 74 and 76 has a thickness (projecting in from the conical wall 60) of approximately 1/8 n .
In operation the material first traverses the bars 74 and 76 which tend to deflect material away from the wall then across the openings 66 and 68. The rods 70 and 72 extend substantially in the direction of move-ment of the material and thus do not obstruct movement of the material around the cyclone, however they tend to block the opening to bast fibre while permitting the escape of dross material through the openings 66 and 68.
The openings 66 and 68 are enclosed on the outer surface of the cyclone by a housing generally indicated at 78 (see Figure 5) that provides a passage 80 for the dross material escaping through the outlets 66 and 68 and directs this material down and out of the unit as indicated by the arrow 82 in Figure 4. Thus the dross material leaves the equipment in operation and is thus spread around the field due to the movement of the equipment around the field to pick up the straw and thereby facilitates its functioning as fertilizer.
The preferred arrangement of the present invention as above described incorporates the separator device as a part of a pneumatic cyclone but this is not essential. Other conventional screening means may be used. For example, air may be separated from the decorticated flax using a conventional cyclone and the , dross material separated from the bast using a conven-i tional screening means adapted to make the separation.
However, such arrangements generally significantly increase the weight of the unit and could result in significantly impairing mobility of the equipment.
~^ 5~
Bast material leaves the cyclone 44 through the apex outlet 62 and is introduced into a suitable baling mechanism generally indicated at 84. The baler ~' , ':, ' , . , 1093~1Z
is provided with the conventional reciprocating plunger mechanism 86 to form the bale which is ejected as indicated by the arrow 88 to provide bale 90 that may be transported to the site where it is finally used.

The flax is not a fodder crop similar to for example alfalfa, and it has been found that the speed of the baler can be slowed down to about 6 or 8 strokes as compared with the strokes of the conventional baler.

Each of the elements such as the shredder 22, disc 34 and the conveyers 16 and 18 may be driven by any suitable means such as hydraulic motors. Power requirements of the equipment are relatively small and therefore the power source may be the same as the equipment used to pull the device through the field i.e.
the power take-off from a suitable tractor. In the arrangement shown the power take off from the tractor is used to power the hydraulic pump schematicall~
indicated at 96 in Figure 2 which in turn _ g _ ~09341Z
drives the various hydraulic motors. The baler is also driven from the power take-off while the pick-up 10 is driven by rotation of the wheel 92 by ground engagement and through the drive chain 94 (see figure 2).
The bast rich fraction that is baled generally contains about 60% bast 40 dross as is normally best suited for pulping.
