[0053] Like reference numerals are used for like features throughout the drawings, where appropriate.

[0054] It will be appreciated that the Figures, whilst illustrating various aspects and features of the present disclosure, are not exhaustive and / or exclusive, and the apparatus and methods disclosed herein are not limited to the exact form shown. It will be appreciated that features of the embodiments described herein (and for example shown in the figures) may be combined.

[0055] Detailed description

[0056] Aspects and features of certain examples and embodiments are described herein.

[0057] The present disclosure relates to an apparatus and method for gathering plant material, for example when harvesting plant material. 173281 / 03 P20025632W001

[0058] By way of illustration, but not limitation, Figs. 1 to 9 show various embodiments for the apparatus.

[0059] The apparatus 10 comprises a conveyor 20 for transporting plant material 5, and comprises a support structure 40 configured to support a receiver 30 for receiving plant material 5 which has been transported by the conveyor 20. The receiver 30 is separable from the support structure 40, so as to remove the receiver 30 and any received plant material 5 from the apparatus together.

[0060] This provides an integrated apparatus which both conveys (by the conveyor 30) plant material (for example plant material which is cut during harvesting), and also allows plant material to be gathered (in the receiver 30) for example in a stacked configuration (stack 6). This may assist with efficiently gathering (loading) plant material.

[0061] In this regard, having the conveyor 30 and the receiver 40 provided within a single integrated apparatus means that it is not necessary to coordinate multiple discrete apparatuses when gathering plant material. In this regard, the apparatus may be considered a self-loading system. This can be compared against, for example, arrangements not in accordance with the present disclosure using a first vehicle (e.g. tractor) to cut plant material, and a physically separate second vehicle (e.g. a truck with a trailer bed) on which plant material is stacked after being cut, the second vehicle being driven next to the first vehicle. Compared to such arrangements, the apparatus of the present disclosure may be more fuel efficient (requiring only a single apparatus, which may be mounted on a single vehicle), less costly, take up less space, and require less human effort than operating multiple apparatuses.

[0062] Furthermore, since the receiver 30 of the present disclosure is configured to be separable from the support structure 40 of the apparatus, this can furthermore provide a fast and effective way of unloading plant material 5. Since the receiver 30 is configured to be removed together with plant material 5, this can assist with maintaining plant material in a desired arrangement (for example a stacked configuration) during unloading. This can be compared against, for example, unloading plant material without any such separable receiver 30 (for example tipping plant material from a trailer bed of a truck onto the ground) which may cause the plant material to fall in a disorderly mess.

[0063] In embodiments, the apparatus (that is, the conveyor 20, receiver 30 and support structure 40, and optionally any other parts of the apparatus described herein) is attachable (and in use, attached) to a (single) vehicle 50, such as a tractor. This allows the apparatus to be mobile, and movable to different locations (for example within a field of plant crop) for gathering plant material. It will be appreciated that a vehicle other than a tractor could instead be used. 173281 / 03 P20025632W001

[0064] With regards to the conveyor 20, in embodiments, the conveyor is configured to transport plant material to a position above (higher than) the receiver 30. Thus, in embodiments, an end 21 of the conveyor 20 is (positioned) above (higher than) the receiver 20.

[0065] In embodiments, the conveyer 20 is configured to transport plant material to a position directly (vertically) above the receiver 30 (so that the end 21 of the conveyor 20 is directly (vertically) above the receiver 20). In embodiments, the conveyer 20 is configured to transport plant material to a position directly (vertically) above an entrance 31 to the receiver 30 (so that the end 21 of the conveyor 20 is directly (vertically) above the entrance 31 to the receiver 20). Thus, in embodiments (an entrance 31 to) the receiver 30 is positioned below (an end 21 of) the conveyor 20. In such embodiments, plant material transported by the conveyor 20 can fall into the receiver 30 under the influence of gravity alone. The apparatus may, however, be configured to allow a human worker to be present, for example to guide plant material 5 (plant stalks 2 with leaves 3 thereon) into the receiver, for example into a stacked configuration within the receiver.

[0066] Alternatively, it would be possible for the conveyer to transport plant material to a position above, but horizontally offset from, the receiver 30. In such embodiments, plant material arriving at the end 21 of the conveyor 20 could then be moved into the receiver (for example by a human worker).

[0067] In embodiments, the conveyor 20 is configured so that plant material 5 transported by the conveyor is raised during transport, from a first height (at which plant material is initially provided to the conveyor, for example at a start 22 of the conveyor) to a second (greater) height (at which plant material exits the conveyor, for example at the end 21 of the conveyor).

[0068] Thus, in embodiments, the conveyor 20 is configured to, whilst transporting plant material 5, lift plant material upwards. This may assist with lifting plant material 5 away from the ground or other plants within a field of plant crop.

[0069] Thus, in embodiments, at least part of the conveyor 20 is inclined, so that the end 21 of the conveyor 20 is at a greater height (higher, in a vertical, z, direction) than the start 22 of the conveyor 20.

[0070] In embodiments, the end 21 of the conveyor 20, in use (for example when the apparatus is fitted to a vehicle, for example a tractor) is at a height of at least 1 metre above the ground, or at least 1.5 meters, or at least 1.8 meters, or at least 2 meters above the ground. This can allow a relatively large receiver 30 to be provided beneath the end of the conveyor, so that a relatively large amount of plant material 5 can be gathered. 173281 / 03 P20025632W001

[0071] In embodiments, the support structure 40 (in addition to supporting receiver 30 also) supports (at least part of) the conveyor 20. Thus, in embodiments, the conveyor 20 is operably coupled to the receiver 30. In embodiments, the relative position between the (end 21 of) the conveyor 20 and the receiver 30 (and the relative position of the conveyor 20 compared to the support structure 40) is fixable, and in embodiments fixed (so that the conveyor 20 cannot be moved relative to the receiver 30). This can help to ensure that plant material is deposited from the end of the conveyor at a reliable position relative to the receiver.

[0072] In embodiments the conveyor 20 is configured to transport plant material along a path (at least part of) which is inclined and which also has one or more changes in direction (in a horizontal x-y direction). This is shown, for example at least in Figs. 2 and 3. This can allow the conveyor to achieve a relatively significant height gain whilst remaining relatively compact.

[0073] Thus, in embodiments, the conveyor 20 comprises at least one change in direction.

[0074] In embodiments, the conveyor 20 comprises a first portion 23 (for example having a start which corresponds to the start 22 of the conveyor 20) which extends (conveys plant material) in a first direction, and a second portion 24 (for example having an end which corresponds to the end 21 of the conveyor 20) which extends (conveys plant material) in a second, different, direction compared to the first portion. In embodiments the first portion 23 extends in a direction substantially perpendicular to the second portion 24 of the conveyor 20.

[0075] In embodiments, the apparatus is configured so that, when attached to a vehicle 50 (for example a tractor) the conveyor 20 at least partially wraps around the vehicle, so that plant material 5 is transported at least partially around the vehicle as it is transported (and raised) by the conveyor 20. This may provide a relatively compact arrangement.

[0076] In embodiments, a (the first) portion 23 of the conveyor is configured to extend (transport plant material) along a side of a vehicle 50 (when the apparatus is attached to a vehicle), in embodiments extending only along a single side of the vehicle 50.

[0077] In embodiments, a (the second) portion 24 of the conveyor 20 is configured to extend (transport plant material) at a rear of a vehicle 50 (when the apparatus is attached to a vehicle), in embodiments extending only at a rear of the vehicle 50.

[0078] The conveyor could comprise a single, continuous, conveyor arrangement (a single, continuous moving endless surface), which transports plant material from the start 22 of the conveyor 20 to the end 21 of the conveyor. In such embodiments, the first and second portions 23, 24 of the conveyor 20 could be portions of a single, continuous, conveyor arrangement. 173281 / 03 P20025632W001

[0079] Alternatively, and in embodiments, the conveyor 20 may comprise multiple, discrete, conveyor arrangements 25, 26 (multiple, discrete, moving endless surfaces), arranged in series to transport plant material from the start 22 of the conveyor 20 to the end 21 of the conveyor, for example as shown in the Figures. In other words, the apparatus may comprise multiple, discrete, conveyor arrangements 25, 26 (multiple, discrete, moving endless surfaces), together defining a path along which plant material is conveyed.

[0080] In such embodiments, a first conveyor arrangement 25 may form a first portion 23 of the conveyor (the first portion 23 for example having the features described herein), and a second conveyor arrangement 26 may form a second portion 25 of the conveyor (the second portion 25 for example having the features described herein).

[0081] Thus, in embodiments, the first conveyor arrangement 25 (for example having a start which corresponds to the start 22 of the conveyor 20) may extend (convey plant material) in a different direction compared to the second conveyor arrangement 26 (for example having an end which corresponds to the end 21 of the conveyor 20). For example, the second conveyor arrangement 26 may extend (convey plant material) in a direction substantially perpendicular to the first conveyor arrangement 25.

[0082] In embodiments, a (the first) conveyor arrangement 25 is configured to extend (transport plant material) along a side of a vehicle 50 (when the apparatus is attached to a vehicle), in embodiments configured to extend only along a side of a vehicle 50.

[0083] In embodiments, a (the second) conveyor arrangement 26 is configured to extend (transport plant material) at a rear of a vehicle 50 (when the apparatus is attached to a vehicle), in embodiments configured to extend only at a rear of a vehicle 50.

[0084] However, it would be possible for the conveyor 20 to be subdivided differently (for example so that the first conveyor arrangement 26 additionally extends at least partially along the rear of the vehicle, or so that the second conveyor arrangement 26 additionally extends at least partially along the side of the vehicle).

[0085] In embodiments, the apparatus has only two conveyor arrangements 25, 26 (provided in series) for transporting plant material. However, it would be possible for the conveyor 20 to be subdivided into more than two conveyor arrangements.

[0086] In use, plant material 5 may initially be provided to the first portion 23 of the conveyor 20 (to the first conveyor arrangement 24), and then transported to the second portion 24 of the conveyor (to the second conveyor arrangement 26) from which it is received by the receiver 30.

[0087] Plant material may initially be provided to the conveyor 20 in any suitable and desired way. 173281 / 03 P20025632W001

[0088] For example, a human worker could place plant material 5 on the conveyor 20, for example after cutting the plant material 5 from a plant in a field of crop as part of the harvesting operation.

[0089] Alternatively, and in embodiments, the present apparatus may be used in combination with a mechanical cutter, for cutting plant material 5 from plants in a field of crop. In embodiments, the present apparatus comprises a mechanical cutter 27 (as part of a single integrated apparatus which can be attached to a single vehicle 50).

[0090] In embodiments, a mechanical cutter 27 is provided at an infeed to the conveyor 20 (before or at the start 22 of the conveyor 20). This allows plant material to be cut and directly transferred to the conveyor 20.

[0091] In embodiments, the mechanical cutter 27 comprises a cutting blade (for example a cutting disk) provided on an arm 28 which supports at least part of the conveyor 20 (for example supporting the first portion 23 (first conveyor arrangement 25)). In embodiments, mechanical cutter 27 is arranged to cut plant material 5 by cutting a plant stalk 2 from a plant in situ in a field of crop.

[0092] In embodiments, a (the first) portion 23 of the conveyor 20 (the first conveyor arrangement 25) is configured to transport plant material 5 in the same orientation as provided to the mechanical cutter 27. In embodiments, the first portion 23 of the conveyor 20 is configured to transport plant material 5 with plant stalks 2 pointing substantially vertically (upright) (in other words, so that plant material 5 is transported the same orientation in which it grows). This could be achieved in any suitable and desired way, for example by using a first conveyor arrangement 25 comprising one or more gripping elements (for example metal pins) for gripping and holding plant material 5 in the desired orientation. The gripping elements could, for example, be provided on a moving chain, or a pair of opposing chains, for example supported within the arm 28.

[0093] One or more (other) portions of the conveyor 20 may transport plant material 5 in an orientation which is different to the orientation in which plant material grows on a plot crop.

[0094] In embodiments, a (the second) portion 24 of the conveyor 20 (the second conveyor arrangement 26) (which includes the end 21 of the conveyor 20, from which a plant material 5 is received by the receiver 30) is configured to allow plant material 5 to be transported with plant stalks 2 (of successive plants) oriented in the same direction as one another, so that plant material 5 can be (is) provided to the receiver 30 with plant stalks 2 oriented in a same direction as one another. This can assist with providing plant material to the receiver 30 in an orderly fashion, so that it can be organised within the receiver 30.

[0095] In embodiments, a (the second) portion 24 of the conveyor 20 (the second conveyor arrangement 26) (which includes the end 21 of the conveyor 20, from which a plant material 173281 / 03 P20025632W001

[0096] 5 is received by the receiver 30) is configured to support plant material 5 lying flat (with plant stalks 2 oriented substantially horizontally) on the conveyor, in embodiments with plant stalks lying across the width of the conveyor (perpendicular to the direction of transport). This can allow plant material to be stacked neatly when received by the receiver 30, for example as illustrated in Fig. 2.

[0097] Thus, in embodiments, the conveyor 20 comprises a first portion 23 for transporting plant material with plant stalks pointing substantially vertically, and a second portion 24 for transporting plant material with plant stalks lying flat and substantially horizontally thereon.

[0098] In embodiments, the conveyor 20 is configured so that the orientation of plant material 5 is changed during transport of plant material, for example, from an orientation in which plant stalks 2 extend substantially vertically to an orientation in which plant stalks 2 extend substantially horizontally. Such a change to a horizontal orientation may assist with neatly stacking the plant material 5 within the receiver 30.

[0099] In embodiments, a (the second) portion 24 of the conveyor 20 (the second conveyor arrangement 26) is sized to support plant material 5 with plant stalks 2 oriented horizontally (lying flat on the conveyor). Thus, in embodiments a (the second) portion 24 of the conveyor 20 has a width (perpendicular to the direction of transport of plant material 5) which is at least 30 cm, or at least 50 cm, or at least 80 cm, or at least 1 metre.

[0100] In embodiments, a (the second) portion 24 of the conveyor 20 (the second conveyor arrangement 26) comprises a conveyor belt (an endless loop of flexible material). This may provide good support for the plant material 5. Other types of conveyor could however be used if desired, such as a chain conveyor.

[0101] In embodiments, a (the second) portion 24 of the conveyor 20 (the second conveyor arrangement 26) is inclined, so that plant material is raised as it is transported, and is in embodiments planar (forms a planar, in inclined, path for transporting plant material 5).

[0102] In embodiments, the apparatus is arranged so that plant material 5 can be transferred (is deposited) (directly) from the first conveyor arrangement 25 onto the second conveyor arrangement 26, and can then be transferred (deposited) (directly) from the second conveyor arrangement 26 into the receiver 30. In embodiments, the apparatus comprises a guard 29 (guard structure) configured to prevent plant material from falling off the apparatus during transport between the first and second conveyor arrangements 25, 26.

[0103] Regarding the receiver 30, the receiver 30 is in embodiments provided beneath the end 21 of the conveyor 20.

[0104] In embodiments, the apparatus is configured so that, when the apparatus is attached to a vehicle 50, the receiver 30 is positioned at the rear of the vehicle 50, in embodiments 173281 / 03 P20025632W001 only at the rear of the vehicle (and not provided on or extending along either side of the vehicle 50). This may provide a relatively compact arrangement.

[0105] In embodiments, the receiver 30 (when supported on the support structure 40 of the apparatus), comprises a base portion 32 and one or more side portions 33, 34. In use, plant material 5 received by the receiver 30 can be supported on top of the base portion 32 and between the side portions 33, 34. This can be seen, for example in Fig. 4. Such a configuration may assist with containing plant material 5, and for example holding plant material 5 in a stacked configuration, as compared for example to a base portion only (for example as would be the case if plant material were to be gathered on a trailer bed).

[0106] In embodiments, the receiver 30 comprises only two, opposing, side portions 33, 34 (forming opposite sides of the receiver 30, for example to support opposite sides of a stack 6 of plant material). In such appointments, one or more (other) (opposing) sides of the receiver may be open.

[0107] In other words, the material forming the receiver 30 may comprise only two, opposing side portions 33, 34 (and a base portion 32), such that one or more (other) (opposing) sides of the receiver comprise no material. In such embodiments, the receiver 30, when formed of a flexible material, may comprise a belt of material (in other words, forming a sling), in embodiments with each end of the belt of material being attachable (configured to be attached) to the support structure 40 of the apparatus.

[0108] Such a configuration may sufficiently support plant material 5 is within the receiver 30 (when attached to the apparatus and also when removed from the support structure 40 of the apparatus, regardless of the exact length of plant stalks which may overhang the receiver), whilst also allowing plant material to be easily removed from the open sides at a later stage for example when plant material is to be processed (e.g. cured or defoliated (by removing leaves from plant stalks)).

[0109] In embodiments, the receiver 30 (also) comprises an opening 31 at the top of the receiver, for receiving plant material 5. In embodiments, the top of the receiver 30 is entirely open. This can allow plant material 5 to be deposited at any desired position within the receiver, for example to form a stack 6 of plant material (see for example Fig. 2).

[0110] In embodiments, the receiver 30 is sized to receive (and to support simultaneously) plant material 5 comprising plural plant stalks 2 with leaves 3 thereon.

[0111] In embodiments, the receiver 30 is sized to support (contain)(hold) received plant material 5 in a stacked configuration (to support a stack 6 of plant material). In embodiments, the plant material 5 is stacked (and supported by the receiver 30) with plant stalks 2 oriented in a same direction, for example with plant stalks 2 oriented horizontally, and arranged in one or more (in embodiment plural) rows and one or more (in embodiments plural) columns. 173281 / 03 P20025632W001

[0112] In embodiments, the receiver 30 (when supported on the support structure 40 of the apparatus) has a depth D (of the base portion 32, extending between the open sides of the receiver 30, in embodiments corresponding to the direction which plant stalks are to be oriented) which is at least 50%, in embodiments at least 70% of the length of a stalk 2 of plant material 5 to be received. This may provide good support of plant stalks. In embodiments, the depth D is at least 20 cm, or at least 50 cm, or at least 80 cm, or at least 1 metre, or at least 1.2 metres.

[0113] In embodiments, the receiver 30 (when supported on the support structure 40 of the apparatus) has a width W (of the base portion 32, extending between the first and second side portions 33, 34) sized to support (contain) plural plant stalks 2 with leaves 3 thereon, in embodiments at least three, or at least five plant stalks with leaves thereon. In embodiments, the width W is at least 30 cm, or at least 50 cm, or at least 80 cm, or at least 1 metre, or at least 1.2 metres, or at least 1.4 metres. In embodiments the width, W, is greater than the depth D

[0114] In embodiments, the receiver 30 (when supported on the support structure 40 of the apparatus) has a height H (from the base portion 32 to the top opening 31, corresponding to the height of the first and second side portions 33, 34) sized to contain plural plant stalks 2 with leaves 3 thereon, the plant stalks 2 oriented horizontally, in embodiments at least three, or at least five plant stalks with leaves thereon. In embodiments, the height H is at least 30 cm, or at least 50 cm, or at least 80cm, or at least 1 metre, or at least 1.2 metres, or at least 1.4 metres. In embodiments the height H, is greater than the depth D. In embodiments, the height H is greater than the width W. .

[0115] In embodiments, the receiver 30 comprises flexible material, in embodiments being formed at least partly (in embodiments substantially) of flexible material. Thus, in embodiments the base portion 32, and the side portions 33, 34 of the receiver 30 comprise (are formed of) flexible material.

[0116] This may provide a more cost-effective configuration than, for example, a receiver formed of a rigid material such as metal. In this regard, when the present receiver 30 is removed from the apparatus with plant material 5 therein, it may be desired to replace it with a new (empty) receiver 30 immediately to continue gathering material, and so a low cost for the receiver 30 may be helpful.

[0117] A receiver 30 comprising flexible material may also allow (in embodiments allows) plant material 5, after being removed from the apparatus with the receiver 30, to be at least partially wrapped by the receiver. This may assist with containing the plant material (and for example retaining the plant material in a stacked configuration), for example when 173281 / 03 P20025632W001 transporting the plant material 5 (in the receiver 30) for onward processing, for example such as transport to a curing barn.

[0118] In embodiments, the flexible material of the receiver 30 is configured so as to permit (at least part of) the receiver 30 to hang from the support structure 40. In embodiments, the flexible material of the receiver 30 has a strength sufficient to support plant material (for example plural plant stalks 3 with leaves 2 therein, for example in a stacked configuration) without breaking.

[0119] In embodiments the flexible material of the receiver 30 comprises fabric, for example a woven fabric or nonwoven fabric. The flexible material may comprise natural fibres (for example comprising cellulosic fibres, for example comprising cotton, hessian, bamboo or other natural fibres, the flexible material for example comprising a cloth or canvass), and / or artificial fibres (for example comprising plastic or other polymeric material).

[0120] In embodiments, the base portion 32, and the side portions 33, 34 of the receiver 30 are formed substantially continuously with one another (so that a substantially continuous, same, piece of material extends from one side portion 33 to the opposing side portion 34). This can allow the receiver 30, when removed from the support structure 40 of the apparatus to be wrapped around the plant material received therein, for example to help to contain the material.

[0121] In embodiments, the base portion 32 (and in embodiments each of the side portions 33, 34) are each formed of substantially continuous material (in the depth D direction of the receiver 30). This may provide good support to plant material received within the receiver 30.

[0122] In embodiments the receiver 30 (the base portion 32, and the side portions 33, 34 of the receiver 30, and ignoring any attachments 35 for attaching to the support structure 40) is formed of only (consists of) a single piece of flexible material. Such arrangements are shown, for example, in Figs. 2 and 4. This may provide a relatively cost-effective arrangement.

[0123] However, it would alternatively be possible to form the receiver of plural pieces of material. For example, the receiver 30 could be formed of plural strips of material or strings, provided adjacent one another in the depth D direction of the receiver 30, and each spanning the base portion 32 and side portions 34 of the receiver 30. Such an arrangement could, for example, still allow plant material to be supported, and also wrapped (bound) together once the receiver 30 has been removed from the support structure 40 of the apparatus.

[0124] It will be appreciated that, although the receiver has (adopts) a shape comprising the base portion 32 and side portions 33, 34 when attached to the support structure 40 of the apparatus, the receiver may have (adopt) a different shape when not attached to the support 173281 / 03 P20025632W001 structure 40, for example when the receiver comprises flexible material. In this regard, the receiver 30 may comprise one or more (in embodiments a single) (flat) piece of material which, when attached to the support structure 40 of the apparatus hangs under gravity to adopt a shape comprising the base portion 32 and side portions 33, 34.

[0125] In embodiments, the receiver 30 and / or the support structure 40 comprises one or more attachments 35 for attaching the receiver 30 to the support structure 40. In embodiments, the receiver 30 is supported on the support structure 40 at least at (by virtue of) the one or more attachments 35.

[0126] The one or more attachments may be provided at or near a top of the receiver 30 (for example at or near the top opening 31 to the receiver 30). In embodiment where the receiver 30 comprises flexible material, (at least part of, in embodiments substantially all of) the receiver may hang beneath the attachment(s) 35 when the receiver is attached to the support structure 40.

[0127] In embodiments where the receiver 30 comprises one or more attachments 35 (attachment means), the attachments may be provided within, or in embodiments extend from, the body of the receiver 30.

[0128] In embodiments one or more attachments 35 are provided within, or extend from, either or both side portions 33, 34 of the receiver 30. The attachment(s) 35 may be provided at plural locations on a (or each) side portion 33, 34 of the receiver 30, for example being provided at one or more (or each) each corner of the receiver 30.

[0129] An (or each) attachment 35 in embodiments comprises a flexible loop or tie (for example comprising a flexible material, such as rope or fabric), for looping or tying around at least part of the support structure 40. For example, Fig. 4 shows attachments 35 each in the form of a fabric tie. Alternatively, a (or each) attachment 35 may comprise a hook (comprising (formed of) rigid material) for hooking onto at least part of the support structure 40. In such embodiments, the support structure 40 may comprise one or more elements (for example arms or extensions 41) to which the attachment(s) 35 can be tied, looped or hooked.

[0130] In embodiments attachments 35 comprising flexible loops or ties, or hooks, are configured so that attachments (for example on opposite sides portions 33, 34 of the receiver 30) can be joined (attached (tied or hooked) or grasped) together, in embodiments before and / or after the receiver 30 has been removed from the support structure 40 of the apparatus. This may assist with constraining plant material 5 within the receiver. In this regard, attaching (tying or hooking) the attachments 35 together (to one another) before removing the receiver 30 and plant material 5 from the apparatus can help to constrain plant 173281 / 03 P20025632W001 material within the receiver 30 during removal, so that removal can be performed quickly and without loss of plant material.

[0131] Other forms of attachment 35 would alternatively be possible, for example such as one or more holes (for example reinforced with eyelets) in the receiver 30 to be mounted on a suitable extension of the support structure.

[0132] In embodiments, the support structure 40 comprises a support portion 44 which supports at least part of (in embodiments the entirety of) the base portion 32 of the receiver 30. In embodiments the support portion 44 (additionally) supports at least part of (in embodiments only a lower part, and not an upper part of) one or more side portions (either or both side portions 33, 34) of the receiver 30. In such embodiments, the support portion 44 may comprise a base portion 45 for supporting the base portion 32 of the receiver, and first and second side portions 46, 47, for supporting (at least part of) the first and second side portions 32 and 33 of the receiver. In such embodiments, the support portion 44 is configured to be positioned beneath (and in contact with) the base portion 32 of the receiver 30, and optionally also adjacent (and in contact with) one or more side portions 33, 34 of the receiver 30. An example such support portion 44 can be in Fig. 3.

[0133] In this way, in embodiments where the receiver 30 comprises flexible material, the support portion 44 may assist with supporting (maintaining) the receiver 30 in a shape that allows receipt of plant material in a stacked configuration (as opposed, for example, to having a receiver which hangs freely from attachment(s) 35).

[0134] In embodiments the support portion 44 also comprises a rear portion 48, between the first and second side portions 46, 47 (which in use, spans an open portion between the first and second side portions 32, 33 of the receiver 30). When the apparatus is attached to a vehicle, the rear portion 28 may be positioned between the base portion 45 and a rear of the vehicle, to help support plant material and prevent plant material from falling between the support 40 and the vehicle.

[0135] The support portion 44 may be formed of any suitable and desired (rigid) material. For example, the support portion 44 may comprise (be formed of) a metal. This may impart durability. However, other material could instead be used.

[0136] As discussed here, the receiving portion 30 is separable from the support structure 40, so as to remove the receiving portion 30 and any plant material 5 thereon from the apparatus.

[0137] In embodiments, the apparatus comprises a mechanical ejector 60 to assist with removing the receiver 30 from the support structure 40.

[0138] In embodiments, the mechanical ejector 60 is movable, in embodiments by a mechanical actuator, which is in embodiments (electrically) powered. 173281 / 03 P20025632W001

[0139] In embodiments, the mechanical ejector 60 is configured to move the receiver 30 into a position whereby the receiver 30 and plant material 5 are removed from (slide off of) the apparatus by gravity.

[0140] In embodiments, the mechanical ejector 60 is a movable part of the support structure 40 which supports the receiver 30.

[0141] In embodiments the mechanical ejector 60 comprises the support portion 44 (having any of the features described above).

[0142] Thus, in embodiments, the mechanical ejector 60 is configured to support at least part of (in embodiments the entirety of) the base portion 32 of the receiver 30, and in embodiments to (also) support at least part of (in embodiments only a lower part, and not an upper part of) one or more side portions (either or both side portions 33, 34) of the receiver 30. In such embodiments, the mechanical ejector 60 may comprise a base portion 65 for supporting the base portion 32 of the receiver, and first and second side portions 66, 67, for supporting (at least part of) the first and second side portions 32 and 33 of the receiver. In such embodiments, the mechanical ejector 60 is configured to be positioned beneath (and in contact with) the base portion 32 of the receiver 30, and optionally also adjacent (and in contact with) one or more side portions 33, 34 of the receiver 30.

[0143] The mechanical ejector 60 may also comprise a rear portion 68, between the first and second side portions 66, 67 (which in use, spans an open portion between the first and second side portions 32, 33 of the receiver 30). When the apparatus is attached to a vehicle 50, the rear portion 68 may be positioned between the base portion 65 of the ejector 60 and the vehicle 50, to help support plant material and prevent plant material from falling between the ejector 60 and the vehicle.

[0144] In embodiments, the mechanical ejector 60 is be configured to tilt (rotate) so as to tip the receiver 30 off of the apparatus (and off of the mechanical ejector 60). Thus, the mechanical ejector 60 may be configured so that a single (tilt) movement of the mechanical ejector 60 causes the receiver 30 to be removed from the apparatus. This may provide a quick and effective unloading.

[0145] For example, and in embodiments, the mechanical ejector is configured to move (tilt) so that a base portion 65 of the mechanical ejector 60 (which supports the base portion 32 of the receiver 30) moves from a substantially horizontal orientation to an inclined orientation, so that the receiver 30 is tipped off of the mechanical ejector 60. This movement may also cause a rear portion 68 (in embodiments where that is provided) of the mechanical ejector 60 to exert a pushing force on the plant material in the receiver 30, to assist with urging the plant material 5 and receiver 30 off the support structure. This action is illustrated for example in Fig. 8. 173281 / 03 P20025632W001

[0146] To allow the receiver 30 to be removed (e.g. tipped off) of the support structure 40 (for example as shown in Figs. 8 and 9), the (any) attachments 35 (for example material ties or loops, or hooks) attaching the receiver 30 to the support structure 40 may be detached (disengaged) before actuating (moving) the mechanical ejector. This could be done, for example, by a human worker untying or otherwise detaching the attachments 35.

[0147] It will be appreciated, however, that the mechanical ejector 60 could alternatively or additionally be embodied in other ways.

[0148] Thus, the mechanical ejector 60 could comprise (a movable) part of the support structure 40 which does not support (contact) the base 32 of the receiver 30.

[0149] For example, the mechanical ejector 60 could comprise part of the support structure 40 to which the receiver 30 is attached.

[0150] For example, the mechanical ejector 60 could comprise a mechanical (and electrically powered) release mechanism, configured to release the receiver 30 from one or more attachment(s) 35 that attach the receiver 30 to the support structure 40.

[0151] This could be achieved, for example, by using attachment(s) 35 comprising releasable grip(s) which are mechanically actuatable and thus form a mechanical ejector 60.

[0152] Another option would be to additionally or alternatively configuring one or more arms or extensions 41 to which the receiver 30 is attached as a mechanical ejector 60, for example by configuring said one or more arms or extensions 41 to be movable (for example tilt-able, or retractable) so as to release the receiver 30 from the support structure 40.

[0153] Alternatively, or additionally, the mechanical ejector 60 could comprise a mechanical (and electrically powered) pushing mechanism, configured to push the receiver 30 and plant material 5 thereon off of the support structure 40.

[0154] In embodiments (regardless of the particular configuration of the ejector 60), the ejector 60 may be mechanically (and electrically powered so as to be) movable.

[0155] In embodiments the ejector 60 is not configured to be separated from the (support structure 40 of) apparatus when the receiver 30 and plant material 5 are removed from the apparatus. Thus, in embodiments, the ejector 60 is not separable from (the support structure 40 of) the apparatus.

[0156] In embodiments, the ejector is configured to (after being actuated to assist with removing the receiver 30 and plant material 5 thereon), revert (return) to a position which allows a (new) receiver 30 to be attached to the support structure 40 of the apparatus. This can assist with quickly (immediately) returning the apparatus to a condition that allows plant material to be received (gathered).

[0157] In other words, in embodiments the ejector 60 is movable between a first position which allows a receiver 30 be attached to the support structure 40 of the apparatus (and to 173281 / 03 P20025632W001 receive plant material 5), and a second position which assists with removing the receiver 30 and plant material 5 thereon from the support structure. Thus, the ejector is in embodiments movable from a first position to a second position, and also configured to return (is movable back to) the first position from the second position.

[0158] This is illustrated, for example in Figs. 7 to 9, in which Fig. 7 shows plant material being loaded into (gathered in) a receiver 30 (with the ejector 60 in its first position), Fig. 8 shows the ejector 60 in its second position which assists with removing the receiver 30 and plant material 5 therein from the support structure, and Fig. 9 shows the ejector 60 returned to its first position and fitted with a new receiver 30 ready to receive more plant material.

[0159] As discussed herein, a human worked may assist with operation of the apparatus, for example to attach and detach one or more attachments 35 which attach the receiver 30 to the support structure 40, or for example to assist with guiding plant material 5 from the conveyor 20 into the receiver 30 in a stacked configuration.

[0160] In embodiments, the apparatus comprises a support 42 for a human worker (for example as illustrated in Figs. 5 and 6). In embodiments the support 42 for a human worker is configured (positioned) so that a human worker can reach plant material 5 from the end 21 of the conveyor 20, and direct plant material 5 into the receiver 30. In embodiments apparatus is (also) configured so that human worker can reach from the support 42 to one or more of the attachments 35 which attach the receiver 30 to the support structure 40.

[0161] In embodiments, the support 42 for a human worker is part of the support structure 40 of the apparatus, and in embodiments is (thus) attachable to a vehicle 50 by attaching the support structure 40 to the vehicle. In embodiments, the support 42 for a human worker is positioned (when the apparatus is attached to a vehicle 50) at the rear of the vehicle 50, in embodiments between the vehicle and the receiver 30. This may provide a relatively compact arrangement. Whilst Figs. 5 and 6 show a support 42 for a human worker which comprises a chair, it could alternatively comprise a standing platform or other support.

[0162] In embodiments, the apparatus also comprises a sunshield (sunshade) 43 for protecting a human worker from the sun. The sunshield 43 may be positioned above the support 42 for the human worker (for example as shown in Fig. 5). The sunshield 43 may be formed of any suitable and desired material, for example a metal and / or fabric.

[0163] In embodiments the apparatus is configured so that, when the apparatus is attached to a vehicle 50, one or more of the following are provided (extend) (only) at the rear of the vehicle: at least part of the conveyor 20, the receiver 30, the mechanical ejector 60, the support 42 for a human worker. This may provide a relatively compact arrangement.

[0164] As described herein the apparatus allows plant material to be gathered, for example when harvesting plant material. 173281 / 03 P20025632W001

[0165] In embodiments, the apparatus is configured to (and used to) gather plant material 5 comprising plant stalks 2 with leaves thereon 3. In embodiments, the plant material 5 is plant material that has been cut from plants in a field of crop (for example being cut by a cutter 27 of the apparatus) during harvesting, but which is otherwise unprocessed (for example has not yet been cured). The plant stalks 2 may comprise essentially the entire stalk of the plant.

[0166] In embodiments, apparatus is configured to (and used to) gather plant material 5 from (comprising) tobacco plants.

[0167] Figure 10 is a flowchart showing steps in a method for using the apparatus of the present disclosure.

[0168] In embodiments, the method comprises providing plant material 5 to the conveyor 20 of the apparatus, so as to transport plant material to the receiver 30 (step 91).

[0169] When a desired amount of plant material has been received (gathered) in the receiver, the method comprises removing the receiver 30 and plant material 5 thereon from the support structure 40 of the apparatus (step 92). This may comprise actuating a mechanical ejector 60 to assist with removing the receiver 30 and plant material 5 thereon from the support structure 40.

[0170] The method may also or alternatively comprise performing other steps as consistent with the present disclosure.

[0171] For example, the method may comprise, prior to providing plant material 5 to the conveyor, attaching a receiver 30 to the support structure 40 of the apparatus. This may comprise, for example, tying, looping (or hooking) one or more material ties or loops (or hooks) of the receiver around part of the support structure 40.

[0172] The method may comprise cutting plant material 5 from plants (for example one by one), for example in a field of crop, and then (in embodiments immediately) providing the plant material 5 to the conveyor 20 (for the plants one by one). In embodiments, the method comprises cutting the plant material 5 using a cutter 27 of the apparatus, and embodiments directly transferring plant material from the cutter 27 to the conveyor 20.

[0173] In embodiments, the method comprises operating the conveyor 20 continuously when gathering planter material, so as to continuously transport plant material provided thereto to the receiver 30.

[0174] In embodiments, the method comprises a human worker assisting with transferring plant material 5 from an end 21 of the conveyor 20 into the receiver 30, so as to arrange plant material 5 in a stacked configuration in the receiver.

[0175] In embodiments, the method comprises, when a desired amount of plant material has been received (gathered) in the receiver 30, halting the conveyor 20, and detaching the attachment(s) 35 which attached the receiver 30 to the support structure 40. This could be 173281 / 03 P20025632W001 done as part of actuating a mechanical ejector 60. Alternatively, (and in embodiments is) the method comprises detaching the attachment(s) 35 (for example by manually untying, unlooping (or unhooking) one or more material ties or loops (or one or more hooks) of the receiver from support structure 40) prior to actuating a mechanical ejector 60 (in this case the mechanical ejector may, for example, cause a part of the support 40, for example which supports a base of the receiver 30 to move to a position which causes the receiver 30 to move off of the support 40 under the influence of gravity). In embodiments, the method comprises allowing the receiver 30 with plant material 5 thereon to fall to the ground. In embodiments, the method comprises tying or hooking together the ties, loops or hooks of the receiver 30 to help maintain plant material in a stacked configuration even when removed from the support structure 40.

[0176] In embodiments, the method comprises (once the receiver 30 with plant material 5 thereon has been removed from the support structure 40), returning the mechanical ejector to a position in which the support structure 40 of the apparatus can support a (new) receiver 30, and providing a (new) receiver on the support structure 40. After providing a (new) receiver 30 on the support structure 40, the operation (movement) of the conveyor may be resumed, and further plant material may be provided to the conveyor 20 to be received in the (new) receiver 30.

[0177] In embodiments, the method comprises (for example at a later time), collecting any receiver(s) 30 with plant material 5 thereon which have been removed from the apparatus. In embodiments, the receiver(s) 30 with plant material 5 thereon are collected by a separate apparatus compared to the present disclosure (for example using another vehicle). The collection may comprise picking up (lifting) the receiver 30 with plant material 5 thereon using the one or more ties, loops or hooks. The receiver(s) 30 with plant material 5 thereon may then be transported for further processing, for example being transported to a barn or other agricultural building or structure in which the plant material may be cured or defoliated or processed in any other desired way.
