Abstract
An automated planter device for planting seedlings in an obstacle-strewn and/or uneven terrain. A laterally extendable boom is provided at the end of a vertically-moveable arm, which arm may also be swung from side to side. The boom has a plurality of spaced- apart seedling injectors thereon for planting seedlings. Advantageously, due to variably adjustable positioning of the seedling injectors on the boom, obstacles encountered such as tree stumps or medium sized rocks capable of being traversed but which otherwise create an obstacle to a typical seedling planter, may be avoided. The seedling injectors are each coupled via vacuum hoses to a bin mounted on the planter, which vacuum hoses supply seedlings from the bin to the injectors. A powered gantry at the rear of the planter unloads the bin from the planter when empty, and engages and lifts a re-stocked bin containing additional seedlings onto the rear of the device.

Accordingly, in such further aspect of the invention, such planter comprises:
a modified earth excavator having tracks for propelling said modified earth excavator over said ground, having:
(i) a cab thereon for an operator to control said seedling planter;
- 4 -CALLAW\ 2499815\1 (ii) an elongate, powered moveable arm, a distal end of which is vertically- positionable and extendable outwardly from said modified earth excavator;
(iii) an elongate boom member mounted at said distal end of said moveable arm and replacing a normally-situated excavator bucket at said distal end of said moveable arm, said elongate boom member extending parallel to said ground;

In both embodiments, the flexible hoses are preferably are vacuum hoses.
Supply of seedlings to each of said seedling injectors is achieved by the seedling injectors withdrawing air from an associated of said hoses extending to said bin.
In both embodiments, each of the seedling injectors may further be provided with soil tillage appendages protruding from a ventral position thereon, such soil tillage appendages engaging the ground during injection of a seedling in the ground, and adapted to be reciprocated in a back and forth manner at a time of injection of a seedling in said ground by a respective seedling injector.
Advantageously, by the automated seedling planter of the present invention having a boom member mounted on a movable arm numerous advantages useful for efficient and automated planting can be realized.

Advantageously, by the automated seedling planter of the present invention having a boom member mounted on a movable arm numerous advantages useful for efficient and automated planting can be realized.
- 5 -CALLAW\ 2499815\1 By way of few non-limiting examples, as a first example, by having the boom member effectively replace the excavator bucket of a commercially-available excavator, the movable arm and boom member may be swung if desired from a normal position directly in front of the seedling planter to an offset position to the side of the planter.
Specifically, by swinging the moveable arm and boom member to the side of the automated planter. If the boom rotation feature is further incorporated, the boom member when swung to the side may still, if desired, be maintained perpendicular to the direction of travel. In either scenario, by having the boom member and seedling injectors situated to the side of the vehicle, such capability is particularly useful where the spacing of seedling injectors along the length of the boom members crowded and planting seedlings using the seedling injectors in front of the seedling planter would result in some of the planted seedlings being crushed by the tracks when the planter passes forwardly and over them.
As a second example, having seedling injectors mounted on a boom member parallel to the ground advantageously allows for adjustable positioning of at least the seedling injectors on mutually opposite ends of the boom member, .which is extremely useful for obstacle avoidance.
As a third benefit of the design, which provides for mounting of the seedling injectors on the boom member , the ends for such boom member may be made pivotable, wherein one or both of the ends may be temporarily raised to allow for obstacle avoidance and passage of such boom member and seedling planter past such obstacle, such as a remaining tree in an otherwise burned forest area that is being re-planted after a fire, or to avoid a stump in a previously logged area that is now being re-seeded.
Pivotable ends of the boom member also allow for folding over of the pivotable ends, so as to reduce the width of the planter apparatus to allow transportation of such planter apparatus on roadways having a lesser width and thus be able to meet width limitations for travel over such roadways.
In a preferred embodiment of the seedling planter, ends of the boom member are extended and retracted by powered means, such as by a hydraulic cylinder supplied by pressurized hydraulic fluid from the vehicle. A pair of hydraulic cylinders, for example, may be mounted proximate mutually opposite respective ends of the boom member, and when actuated extend or retract such mutually opposite ends. The mutually opposite ends typically

A pair of hydraulic cylinders, for example, may be mounted proximate mutually opposite respective ends of the boom member, and when actuated extend or retract such mutually opposite ends. The mutually opposite ends typically
- 6 -CALLAW\ 2499815\1 have mounted thereon a seedling injector, and in such manner the position of each seedling injector at such mutually opposite ends of the boom member may be individually altered. This feature is particularly advantageous if an obstacle were to be encountered on the terrain being seeded, and relocation of one seedling injector on the boom member is needed to temporarily avoid the obstacle to allow further progression of the automated seeder, or to allow a non-uniform positioning of a seedling which is unable to be located in a uniform position due to an obstacle such as tree stump, rock, or the like.
In a refinement, the boom member may be provided with powered separator means thereon for altering a distance separating two or more seedling injectors on said boom member from each other. The powered separator means is actuated and controlled by the operator from the cab of the seedling planter. The powered separator means for varying or altering the separation of the plurality of seedling injectors between each other may take the form of hydraulic cylinders or other means of motive power such as electric motors driving gearing which relocates the seedling injectors along the boom member. Such feature advantageously allows the avoidance of interference of a seedling injector on the boom member with a local obstacle, such as a tree stump, and may also allow variably adjust the separation distance of seedling injectors on the boom member to quickly allow more dense or less dense planting of seedlings.
In an embodiment of the invention where the automated seedling planter is constructed by modifying a commercially-available earth excavator and the excavator bucket replaced by the boom member of the present invention, the powered means for extending and retracting ends of said boom member is coupled to and controlled by hydraulic pressure lines which otherwise would have been used by said operator to control said otherwise normally-situated excavator bucket on said moveable arm. In such manner the automated seeding apparatus may be relatively easily manufactured from modifications made to a commercially¨available vehicle with only retrofitting of a commercially ¨available excavator being required.
Depending on the types of seedlings, the quality and fertility of the soil in which the seedlings are being planted, and local meteorological conditions such as the amount of annual rainfall received, the spacing between planted seedlings may wish to be adjusted, prior to commencing seeding.

- 7 -CALLAW\ 2499815\1 While altering the distance separating the seedling injectors along the boom member may be done using powered means, alternatively, the separation of the seedling injectors on the boom member may be manually adjusted, prior to the commencement of seedling planting, so as to thereby beforehand adjust the spacing of seedlings being planted. In such an embodiment each seedling injector mounted on said boom member is further provided with a position adjustment mechanism to allow altering or varying spacing of seedling injectors along said boom member. Such position adjustment means may be a powered means, such as a hydraulic cylinder, or may be a manual relocation means, such as a series of slidable positions with a manually operated pin which may be inserted to thereby lock each seedling injector at a desired slidable position along the boom member. Where a manual relocation capability is provided, an operator may, prior to commencement of planting, manually adjust the position of the seedling injectors along the boom member.
Such adjustment mechanism also allows more seedling injectors to be added on the boom member and the spacing of remaining seedling injectors already mounted on the boom member to be slidably adjusted, so as to maintain uniform spaced apart distance between each.
In a further refinement, the boom member is comprised of two half-members extending perpendicularly outwardly from respective mutually opposite sides of said distal end of said moveable arm. Each of the half-members are provided with a pivotable wrist member pivotably mounted at an outboard end of each of said half-members. The pivotable wrist members are each respectively coupled to a respective hydraulic cylinder to allow powered upward pivoting of each wrist member when the respective hydraulic cylinder is actuated by said operator. In such manner, with selective upward pivoting of the wrist members, low obstacles such as stumps can be passed over by the seeder planter. Also, upward pivoting of both wrist members effectively decreases the width of the boom member, useful for transporting the automated seedling planter over roadways of lesser width.
In a further refinement, a boom-rotating means may be provided at the distal end of said moveable arm, for rotating said boom member within a plane parallel to said ground.
Typically, the boom-rotating means will only allow a maximum rotation in one direction of a 900 arc, due to otherwise causing twisting or parting of flexible tubing lines used in conveying seedlings from the bin to each of the seedling injectors (see further discussion of flexible tubing lines, below). Preferably, the boom-rotating means is powered to allow the planter-

operator to rotate the boom member remotely from the cab of the seedling planter.
In an embodiment of the invention where the automated seedling planter is constructed by modifying a commercially-available earth excavator and the excavator bucket replaced by the boom member of the present invention, the boom-rotating means is may be powered by and physically coupled to hydraulic pressure lines which otherwise would have been used by said operator to control said normally-situated excavator bucket on said moveable arm.
In a further aspect of the present invention, the design lends itself to being able to load and unload a bin containing seedlings, which bin is transported by the seedling planter of the present invention.
Accordingly, in a further refinement of the present invention, the seedling planter further comprises a powered gantry for lifting the bin onto the seedling planter, and for demounting said bin from the vehicle when supply of seedlings therein is exhausted. The powered gantry may further possess bin-engaging apparatus for releasably engaging said bin to allow said powered gantry to lift said bin onto said vehicle and to demount said bin from said vehicle.

In the following description, similar and functionally equivalent components in the drawings are identified with corresponding same reference numerals.
Reference to an element in the singular, such as by use of the article "a" or "an" is not intended to mean "one and only one" unless specifically so stated, but rather "one or more".
Fig.s 1-4 depict an automated seedling planter 10 of the present invention for planting seedlings 42 in ground 11. Fig. 1 depicts a forward perspective view (Fig. 1) the automated seedling planter 10; Fig. 2 a rear perspective view; Fig. 3 a frontal perspective view when a side method of planting seedlings is employed (typically when seedling spacing is such that tracks 14 of the vehicle 12 would otherwise overrun the planted seedlings 42 if a frontal planting position of moveable are 20 was employed), and Fig. 4 being a rear perspective view of a further embodiment of automated seedling planter 10 which employs a boom-rotating means 70 to rotate the boom 24 in a plane parallel to ground 11.
As may be generally seen from Fig.s 1-4, automated seedling planter 10 comprises a powered vehicle 12 having tracks 14 for traversing difficult terrain or loose or muddy ground 11. Powered vehicle 12 typically comprises a modified earth excavator having an excavator bucket (not shown) removed from a distal end 22 of a powered articulated moveable arm 20 ,and a boom member 24 coupled to moveable arm 20 at distal end thereof. Moveable arm 20 on tracked vehicle 12 is preferably capable of being swung from side to side of vehicle 12 by the operator as is common for earth excavators.
Proximal end 23 of moveable arm 20 is pivotably secured to vehicle 12.
Advantageously, in place of the excavator bucket (not shown) there is provided an elongate boom member 24 mounted at the distal end 22 of moveable articulated arm 20.
Elongate boom member 24 extends horizontally and perpendicularly outwardly from distal end 22 of moveable arm 20.
A plurality of seedling injectors 28 are mounted in spaced relation to each other along a length of elongate boom member 24. Seedling injectors 28 inject seedlings 42 into ground 11 during travel of automated seedling planter 10 in a forward direction as shown in
- 12 -CAL_LAW\ 2499815\1 Fig. 1. Boom member 24 possesses at least a pair (28a, 28b) of seeding injectors 28 mounted on mutually opposite ends (29a, 29b) respectively of boom member 24.
(see Fig. 5) As may be best seen from Fig.'s 5, 9, & 12 seedling injectors 28 each comprise soil-engaging and/or soil tillage members 30a, 30b protruding from a ventral position. Soil tillage members 30a, 30b are configured so as to reciprocate in a back and forth manner as more fully explained herein at the time or immediately prior to injection of a seedling 42 in ground 11 by a respective seedling injector 28, so allow tillage of earth around the seedling 42 or breaking up of ground 11 in preparation for seedling injection in ground 11. Such feature is particularly useful if planting is being done in winter and the ground otherwise be frozen, or if the ground 11 is otherwise hard or compacted, and also for tillage of unwanted plant material at the location of seedling planting.
A seedling bin 40 for containing seedlings 42 on vehicle 12 prior to their being planted by seedling planter 10, may be mounted on seedling planter 10, preferably at the rear of vehicle 12, as shown in Figs. 1-4.
To allow seedlings 42 in bin 40 to be rapidly and efficiently supplied to each seedling injector 28 for planting, the seedling planter 10 of the present invention utilizes a plurality of flexible hoses 44 extending from bin 40 respectively to each of seedling injectors 28. In a preferred embodiment, flexible hoses 44 are vacuum hoses. In such embodiment, the supply of seedlings 42 to each of said seedling injectors 28 is achieved by said seedling injectors 28 withdrawing air from an associated respective vacuum hose 44 extending from such respective seedling injector 28 to bin 40, to thereby withdraw seedlings 42 through such vacuum hose 44 to a respective seedling injector 28 for injection into ground 11.
In a preferred embodiment as best shown in Fig. 5, boom member 24 is provided with powered means 95a, 95b for extending and retracting one or both of mutually opposite ends 29a, 29b of boom member 24, so as to thereby alter distance and/or `d2' separating a pair 28a, 28b of seedling injectors 28a, 28b which are respectively situated at mutually opposite ends 29a, 29b of boom member 24. Powered means 95a, 95b may comprise any motive force, such as a piston and cylinder powered by hydraulic fluid or compressed air, or an electric or pneumatically-powered motor. In a preferred embodiment powered means comprises hydraulic cylinders 95a, 95b as shown in Fig. 5.
Advantageously and by way of illustrative example, as best shown in successive
(see Fig. 5) As may be best seen from Fig.'s 5, 9, & 12 seedling injectors 28 each comprise soil-engaging and/or soil tillage members 30a, 30b protruding from a ventral position. Soil tillage members 30a, 30b are configured so as to reciprocate in a back and forth manner as more fully explained herein at the time or immediately prior to injection of a seedling 42 in ground 11 by a respective seedling injector 28, so allow tillage of earth around the seedling 42 or breaking up of ground 11 in preparation for seedling injection in ground 11. Such feature is particularly useful if planting is being done in winter and the ground otherwise be frozen, or if the ground 11 is otherwise hard or compacted, and also for tillage of unwanted plant material at the location of seedling planting.
A seedling bin 40 for containing seedlings 42 on vehicle 12 prior to their being planted by seedling planter 10, may be mounted on seedling planter 10, preferably at the rear of vehicle 12, as shown in Figs. 1-4.
To allow seedlings 42 in bin 40 to be rapidly and efficiently supplied to each seedling injector 28 for planting, the seedling planter 10 of the present invention utilizes a plurality of flexible hoses 44 extending from bin 40 respectively to each of seedling injectors 28. In a preferred embodiment, flexible hoses 44 are vacuum hoses. In such embodiment, the supply of seedlings 42 to each of said seedling injectors 28 is achieved by said seedling injectors 28 withdrawing air from an associated respective vacuum hose 44 extending from such respective seedling injector 28 to bin 40, to thereby withdraw seedlings 42 through such vacuum hose 44 to a respective seedling injector 28 for injection into ground 11.
In a preferred embodiment as best shown in Fig. 5, boom member 24 is provided with powered means 95a, 95b for extending and retracting one or both of mutually opposite ends 29a, 29b of boom member 24, so as to thereby alter distance and/or `d2' separating a pair 28a, 28b of seedling injectors 28a, 28b which are respectively situated at mutually opposite ends 29a, 29b of boom member 24. Powered means 95a, 95b may comprise any motive force, such as a piston and cylinder powered by hydraulic fluid or compressed air, or an electric or pneumatically-powered motor. In a preferred embodiment powered means comprises hydraulic cylinders 95a, 95b as shown in Fig. 5.
Advantageously and by way of illustrative example, as best shown in successive
- 13 -CALLAW\ 2499815\1 Figs. 6 & 7, should seedling planter 10 approach an obstacle such as a tree stump 52 at a location which would otherwise interfere with seedling injector 28b planting a seedling 42 at such location (ref. Fig. 6), hydraulic cylinder 95b may be actuated to extend end 29b telescopically outwardly from pivotable wrist member 27b of boom member 24, to thereby avoid tree stump 52 when boom member 24 is lowered so as to contact ground 11 and allow seedling injector 28b to then inject a seedling at a location other than at the location of stump 52.
In a refinement, powered means 95a, 95b may be provided for each seedling injector 28 situated along boom member 24 to further provide capability of individually adjusting distances separating not only h the pair of seedling injectors 28a, 28b mounted on mutually opposite ends 29a, 29b of boom member 24 but all individual seedling injectors 28 along boom member 24. Such feature is useful and advantageous for not only avoiding obstacles, such as tree stumps in the example depicted in Figs. 6 & 7 for each seedling injector 28, but is also advantageous for adjusting simultaneously the spacing distances 'd' separating each seedling injector 28 from another. In such manner spacing distance "d1", `d2"
etc. may be varied by the seedling planter operator when using seedling planter 10 at different seedling locations and with different types of seedlings 42, without having the operator of the seedling planter 10 be forced to exit from cab 16 to manually relocate spacing of seedling injectors 28 along boom member 24 in the manner below explained.
If no powered means 95a, 95b is provided for automated re-positioning of seedling injectors 28 along boom member 24, in an alternative embodiment seedling injectors 28 may nonetheless be manually repositioned along boom member 24 via a position-adjustment mechanism 50a, 50b to allow spacing distances 'd' separating each seedling injector 28 from another to nevertheless still be adjusted. Advantageously, this feature allows adjustment of spacing between seedlings, for different seedling locations and with different types of seedlings 42.
In such embodiment, as best showing in Fig. 5 & Fig. 12, each of seedling injectors 28 are slidably mounted on boom member 24 via (and position-adjustment mechanism 50a, 50b comprises) a pair of inverted cup-shaped brackets 53, each bracket member having an aperture 51 therein for receiving a locking pin 50. Boom member 24 is likewise provided with a plurality of apertures 51 therealong for receiving locking pin 50.
Repositioning of a seeding injector 28 along boom member 24 is accomplished by removing locking pin 50,
In a refinement, powered means 95a, 95b may be provided for each seedling injector 28 situated along boom member 24 to further provide capability of individually adjusting distances separating not only h the pair of seedling injectors 28a, 28b mounted on mutually opposite ends 29a, 29b of boom member 24 but all individual seedling injectors 28 along boom member 24. Such feature is useful and advantageous for not only avoiding obstacles, such as tree stumps in the example depicted in Figs. 6 & 7 for each seedling injector 28, but is also advantageous for adjusting simultaneously the spacing distances 'd' separating each seedling injector 28 from another. In such manner spacing distance "d1", `d2"
etc. may be varied by the seedling planter operator when using seedling planter 10 at different seedling locations and with different types of seedlings 42, without having the operator of the seedling planter 10 be forced to exit from cab 16 to manually relocate spacing of seedling injectors 28 along boom member 24 in the manner below explained.
If no powered means 95a, 95b is provided for automated re-positioning of seedling injectors 28 along boom member 24, in an alternative embodiment seedling injectors 28 may nonetheless be manually repositioned along boom member 24 via a position-adjustment mechanism 50a, 50b to allow spacing distances 'd' separating each seedling injector 28 from another to nevertheless still be adjusted. Advantageously, this feature allows adjustment of spacing between seedlings, for different seedling locations and with different types of seedlings 42.
In such embodiment, as best showing in Fig. 5 & Fig. 12, each of seedling injectors 28 are slidably mounted on boom member 24 via (and position-adjustment mechanism 50a, 50b comprises) a pair of inverted cup-shaped brackets 53, each bracket member having an aperture 51 therein for receiving a locking pin 50. Boom member 24 is likewise provided with a plurality of apertures 51 therealong for receiving locking pin 50.
Repositioning of a seeding injector 28 along boom member 24 is accomplished by removing locking pin 50,
- 14 -CAL_LAW\ 2499815\1 slidably repositioning seedling injectors 24 along boom member 24 to a desired position having a uniform desired separation between seedling injectors 28, and reinserting locking pin 50 when each seedling injector 28 is at a location when aperture 51 in inverted cup-shaped bracket 53 is aligned with corresponding aperture 51 in boom member 24 at the desired spacing distance. As shown in Fig. 5, such manual means of repositioning seedling injectors 28 along boom member 24 may be used in combination with powered means 95a, 95b.
In a further refinement of seedling planter 10, and as best shown in Fig. 8 and Fig. 5, further capability of the boom member 24 of pivotable folding of boom member 24 on each of respective opposite sides of moveable arm 20 is provided. In such further refinement boom member 24 is comprised of two half-members 25a, 25b extending respectively perpendicularly outwardly of respective mutually opposite sides of distal end 22 of moveable arm 20. Each of half-members 26a, 26b are provided with a respective pivotable wrist members 27a, 27b pivotably mounted at and to a respective outboard end 29a, 29b of each of half-members 26a, 26b.
Pivotable wrist members 27a, 27b are each respectively coupled to a respective hydraulic cylinder 96a, 96b to thereby allow powered pivotable folding of each wrist member 27a, 27b on a respective half-member 26a, 26b as shown in Fig. 8 when the respective hydraulic cylinder 96a, 96b is actuated by seedling planter operator.
Such above further refinement advantageously provides two important features.
Firstly such further refinement allows one or more seedling injectors 28, and particularly seedling injectors 28a, 28b mounted at mutually opposite ends of boom member 24, to be raised to avoid an obstacle such as a tree stump 52 in the path of boom member 24 (Of course, such obstacle 52 may be alternatively be avoided by raising movable arm 20, or by extending or retracting the seedling injector 28b in the manner explained and as shown in Fig.s 6 & 7).
Secondly, and more importantly, such refinement allows the width of the boom member 24 to be temporarily reduced. This feature in particularly thereby allows for the transportation of the seedling planter 10 along roadways. of limited width, and during transportation of seedling planter 10 from one planting location to another, or to allow the planter 10 to pass between two obstacles, such as two spaced apart trees.
In a further refinement of seedling planter 10, and as best shown in Fig. 8 and Fig. 5, further capability of the boom member 24 of pivotable folding of boom member 24 on each of respective opposite sides of moveable arm 20 is provided. In such further refinement boom member 24 is comprised of two half-members 25a, 25b extending respectively perpendicularly outwardly of respective mutually opposite sides of distal end 22 of moveable arm 20. Each of half-members 26a, 26b are provided with a respective pivotable wrist members 27a, 27b pivotably mounted at and to a respective outboard end 29a, 29b of each of half-members 26a, 26b.
Pivotable wrist members 27a, 27b are each respectively coupled to a respective hydraulic cylinder 96a, 96b to thereby allow powered pivotable folding of each wrist member 27a, 27b on a respective half-member 26a, 26b as shown in Fig. 8 when the respective hydraulic cylinder 96a, 96b is actuated by seedling planter operator.
Such above further refinement advantageously provides two important features.
Firstly such further refinement allows one or more seedling injectors 28, and particularly seedling injectors 28a, 28b mounted at mutually opposite ends of boom member 24, to be raised to avoid an obstacle such as a tree stump 52 in the path of boom member 24 (Of course, such obstacle 52 may be alternatively be avoided by raising movable arm 20, or by extending or retracting the seedling injector 28b in the manner explained and as shown in Fig.s 6 & 7).
Secondly, and more importantly, such refinement allows the width of the boom member 24 to be temporarily reduced. This feature in particularly thereby allows for the transportation of the seedling planter 10 along roadways. of limited width, and during transportation of seedling planter 10 from one planting location to another, or to allow the planter 10 to pass between two obstacles, such as two spaced apart trees.
- 15 -CALLAW\ 2499815\1 In a still further refinement, boom member 24 may be rotatable about an azimuth in a plane parallel to ground 11, as best shown for example comparing Fig.'s 1& 4 , where boom member 24 has been rotated in such a plane from its orientation in Fig. 1 to that shown in Fig. 4. In such further refinement boom rotating means 70 is provided at distal end 22 of moveable arm 20.
Boom rotating means 70 may comprise a roller bearing (not shown), an electric or hydraulically powered motor 71 powering a driving pinion (not shown) , and a gear ring (not shown) fixedly secured to one or the other of the distal end 22 of moveable arm 20 or boom member 24, with the driving pinion causing relative rotation of boom member 24 relative and about distal end 22 of moveable arm 20.
Other configurations of boom-rotating means 70 and means for providing relative rotatable motion of boom member 24 to distal end 22 of movable arm 20 will now occur to persons of skill in the art of hydraulic equipment, and are not further described herein. The feature of a rotatable boom member 24 may alternatively allow the width of the planter 10 to be reduced, instead of using hydraulic cylinders 96a, 96b to foldable collapse boom member 24.
In addition, by having a rotatable boom 24, such allows, when moveable arm 20 is moved to the side of planter 10 as shown in Fig. 3 for side planting, boom 24 to be rotated so as to continue to be perpendicular to the direction of travel of the planter 10.
In preferred embodiments of the seedling planter 10, a powered gantry 80 may be provided for lifting bin 40 onto rear of seeding planter 10, and for demounting bin 40 from planter 10 when supply of seedlings 42 therein is exhausted, as best shown in Fig's 2, 19, &
11, Preferably, powered gantry 80 possesses bin-engaging apparatus 90, such as a pair of hydraulically powered cylinders 99a, 99b driving corresponding lever arms 100a, 100b, for releasibly engaging pinions 101a, 101 b on bin 40 to allow powered gantry 80 to engageably couple to bin 40, and then via cylinders 102a, 102b lift bin 40 to rear of planter 10. The aforesaid equipment operates in reverse to demount bin 40 from rear of planter 10.
In a further refinement, a towable skid 200 on which an additional bin 40' may be carried at shown in Fig. 10 , may be towed by planter 10 to increase the range that planter
Boom rotating means 70 may comprise a roller bearing (not shown), an electric or hydraulically powered motor 71 powering a driving pinion (not shown) , and a gear ring (not shown) fixedly secured to one or the other of the distal end 22 of moveable arm 20 or boom member 24, with the driving pinion causing relative rotation of boom member 24 relative and about distal end 22 of moveable arm 20.
Other configurations of boom-rotating means 70 and means for providing relative rotatable motion of boom member 24 to distal end 22 of movable arm 20 will now occur to persons of skill in the art of hydraulic equipment, and are not further described herein. The feature of a rotatable boom member 24 may alternatively allow the width of the planter 10 to be reduced, instead of using hydraulic cylinders 96a, 96b to foldable collapse boom member 24.
In addition, by having a rotatable boom 24, such allows, when moveable arm 20 is moved to the side of planter 10 as shown in Fig. 3 for side planting, boom 24 to be rotated so as to continue to be perpendicular to the direction of travel of the planter 10.
In preferred embodiments of the seedling planter 10, a powered gantry 80 may be provided for lifting bin 40 onto rear of seeding planter 10, and for demounting bin 40 from planter 10 when supply of seedlings 42 therein is exhausted, as best shown in Fig's 2, 19, &
11, Preferably, powered gantry 80 possesses bin-engaging apparatus 90, such as a pair of hydraulically powered cylinders 99a, 99b driving corresponding lever arms 100a, 100b, for releasibly engaging pinions 101a, 101 b on bin 40 to allow powered gantry 80 to engageably couple to bin 40, and then via cylinders 102a, 102b lift bin 40 to rear of planter 10. The aforesaid equipment operates in reverse to demount bin 40 from rear of planter 10.
In a further refinement, a towable skid 200 on which an additional bin 40' may be carried at shown in Fig. 10 , may be towed by planter 10 to increase the range that planter
- 16 -CAL_LAW\ 2499815\1 may plant with seedling 42, without having to return to a base for restocking of bin 40.
Figs. 9 & 12 show partial cut-away sections of a typical seedling injector 28, and in particular the reciprocating soil tillage members 30a, 30b which protrude from a ventral portion of each seedling injector 28, preferably on either side of where seedlings 42 are 5 supplied to seedling ground penetrating portion 300 of seedling injector 28. Powered means, such as, but not limited to, a pair of double-acting hydraulic piston/cylinders 301a, 301b, are respectively, through cam arms 303a, 303b, coupled to respective rotatable shafts 302a, 302b to convert linear motion of the hydraulic cylinders 301a, 301b to rotary motion, thereby moving respective tillage members 30a, 30b mounted thereon in a back and forth motion 10 when pistons in hydraulic cylinders 301a, 301b are actuated back and forth. Soil around and at the location of injection of seedling 42 may thereby be broken up and tilled. Such advantageously allows for not only breaking up of ground 11 for example when planting of seedlings in winter when ground 11 may be frozen, but further allows for tillage and elimination of weeds and aeration of the soil in the region of seedling planting to thereby assist growth of the planted seedling 42.
