DESCRIPTION OF SPECIFIC EMBODIMENTS OF THE INVENTION

[0039] FIG. 1 shows a system 1 for growing mushrooms, comprising a shelving 2 , comprising multiple support beds 3, 4, 5, 6, 7 for holding compost and casing soil arranged above each other, a picking platform 8 for harvesters 9. The platform 8 is movable with at least a vertical directional component V along the shelving. The picking platform may also comprise a balustrade 29 to prevent harvester 9 from falling off the picking platform 8. The system further comprises a harvesting conveyor 10, comprising a harvesting conveyor belt 11 that extends at least partially along the beds 3, 4, 5, 6, 7 and is supported by a number of guides 12, 13, 14, 15, 16, 17 along which the harvesting conveyor belt 11 is movable. Guides 12, 13, and 14 are coupled to the shelving and at guides 15, 16 and 17 are coupled to the picking platform 8 and are movable together with the platform 8 with at least a vertical directional component V.

[0040] The guides 12, 13, 14, 15, 16, 17 comprise rollers, wherein the harvesting conveyor belt 11 is looped around the rollers 12, 13, 14, 15, 16, 17. The harvesting conveyor 10 is an endless conveyor, and the belt 11 is looped around the guides. The harvesting conveyor 10 is provided with a tensioner 18, which is formed by a movable guide or roller, that can move in order to compensate for the change in the total length of the trajectory of the conveyor belt when the picking platform 8 is moved, either in horizontal H or vertical direction V. In order to move the picking platform 8, it may form part of a picking lorry 19. The picking lorry 19 comprises a frame 19 comprising an arm 23 that extends from the frame 19 with a horizontal directional component, and wherein the arm supports a remote guide 17 at a height level at or below the height of the lowest bed 7 for the harvesting conveyor at a horizontal distance remote from the picking platform 8, such that a height of the harvesting conveyor 10, 11 decreases in the direction from said first guide 16 attached to the picking platform to said remote guide 17 supported by the arm 23. The length of the arm 23 is adjustable, in particular longitudinally compressible by a stopper 25, said stopper 25 located near the end of the beds 3, 4, 5, 6, 7. In this specific embodiment the shelvings are arranged in a cell, wherein the cell comprises a door 24, comprising a cut-out 28 through which the harvesting conveyor 10 extends.

[0041] In the depicted embodiment, the harvesting conveyor 10 is frameless, that is, its belt 11 is supported by the guides, but extends without a cover or frame in between them over at least part of its total length. The harvesting conveyor may preferably extend at least over the entire length L of the shelving. The harvesting conveyor 10 is configured to deliver mushrooms to a delivery point 20 from where they can be processed further. The harvesting conveyor may return at least partly below the shelving (not depicted). It may further comprising a drive 21 for driving the conveyor 10.

[0042] FIG. 2 shows a second embodiment of a system according to the invention. The system is provided with a second harvesting conveyor 22, placed besides the first harvesting conveyor 10, 11 in a width direction. The second conveyor is at a fixed height, allowing harvesters to pick mushrooms from the lowest supports 6 and 6, while standing on ground level. The picking lorry has such construction 23 that the first harvesting conveyor 10, 11 remains above the second harvesting conveyor 22, and for that purpose an additional guide 24 is provided.

[0043] FIG. 3 shows a schematic side view of a harvester 9 on a picking platform 8. In this embodiment of the invention a sweeper 26 is attached to the picking platform 8 and/or lorry19, wherein said sweeper 26 is adjacent to the picking platform 8 and/or lorry 19, and extending in the direction of the bed 3, 4, 5, 6, 7, said sweeper 26 covering the distance between the bed 3, 4, 5, 6, 7 and the harvesting conveyor 10,11. The sweeper 26 is configured to enclose any object in the space between the bed 3, 4, 5, 6, 7 and the harvesting conveyor 10, 11. Such an object may in a non-limitative example be a pillar 30, forming a part of the shelvings. Furthermore, a catch tray 27 is attached along the length of the picking platform 8 and/or lorry 19 at a side facing the beds 3, 4, 5, 6, 7, constructed of a compressible material, configured to intercept tumbling mushrooms. Said catch tray 27 further decreases the amount of spoiled harvest.

[0044] The embodiments shown are examples only and limit in no sense the scope of protection as defined in the following claims.

[0045] The invention also relates to a system for growing mushrooms, comprising a shelving, comprising multiple support beds for holding compost and casing soil arranged above each other, comprising a harvesting conveyor belt, being an endless belt comprising holes for receiving stipes of mushrooms, that extends at least partially along the beds and is supported by a number of guides, along which the harvesting conveyor is movable, wherein the harvesting conveyor belt is at least partially frameless.
