Claims

1. Harvesting device for harvesting fruit hanging from a plant, comprising:

- a frame which is displaceable in a transport direction and carries a loop-like conveyor track which can be driven in circular manner; and

- at least one harvesting bin connected to the conveyor track,

characterized in that the conveyor track lies in a plane which is substantially parallel to the transport direction and which lies at a first acute angle to the horizon in a direction transversely of the transport direction during normal use of the harvesting device.

2. Harvesting device according to claim 1 , wherein at least one catcher is mounted on the at least one harvesting bin, wherein the at least one catcher comprises a flexible catching element for catching fruit and guiding it to the harvesting bin.

3. Harvesting device according to claim 1 or 2, comprising a plurality of harvesting bins and preferably a plurality of catchers, wherein adjacent harvesting bins and catchers connect at least substantially to each other along at least a part of the conveyor track.

4. Harvesting device according to claim 2 or 3, wherein the at least one catcher is displaceable relative to the conveyor track in a direction of extension substantially transversely of the transport direction.

5. Harvesting device according to claim 4, wherein the at least one harvesting bin is displaceable in the direction of extension relative to the conveyor track.

6. Harvesting device according to claim 4 or 5, wherein the at least one harvesting bin and/or the at least one catcher is/are reciprocally displaceable over a carrier mounted on the conveyor track.

7. Harvesting device according to claim 6, wherein the carrier is mounted non-rotatably on the conveyor track and extends substantially transversely of a local longitudinal direction of the conveyor track, and encloses a second angle with an extension of the plane in which the conveyor track lies.

8. Harvesting device according to claim 7, wherein the second angle is greater than the first angle.

9. Harvesting device according to any one of the claims 3-8, wherein the conveyor track has a substantially linear harvesting segment extending substantially in the transport direction along a lower side thereof, and the harvesting device further comprises a first guide placed along the harvesting segment for the purpose of displacing the at least one harvesting bin and/or the at least one catcher in the direction of extension relative to the conveyor track,

wherein the first guide is configured, while the harvesting bin and/or the catcher is being displaced along the harvesting segment counter to the transport direction by the conveyor track, to:

- first move the harvesting bin and/or the catcher away from the conveyor track in the direction of extension;

- hold the harvesting bin and/or the catcher away from the conveyor track while the harvesting bin is being displaced along at least a portion of the harvesting segment; and then

- displace the harvesting bin and/or the catcher back toward the conveyor track counter to the direction of extension.

10. Harvesting device according to any one of the claims 6-9, wherein the carrier comprises a stop for the harvesting bin, which is configured to close the harvesting bin at least partially when the harvesting bin lies against the stop.

11. Harvesting device according to claim 9 or 10, wherein the conveyor track further has an unloading segment along an upper side thereof, and the harvesting device further comprises a second guide placed along the unloading segment for the purpose of opening the at least one harvesting bin at least partially by moving it away from the stop.

12. Harvesting device according to claim 11, further comprising a crate transport system configured to pass collecting crates under the unloading segment in or counter to the transport direction for the purpose of catching fruit from the at least one harvesting bin in the collecting crates.

13. Harvesting device according to claim 12, wherein the crate transport system comprises a buffer for one or more stacks of crates, a de-stacker connected to the buffer, a filling track lying under the unloading segment and connecting to the de-stacker, and a stacker connecting to the filling track.

14. Harvesting device according to any one of the foregoing claims, wherein a running speed of the conveyor track is synchronized with a displacement speed of the harvesting device.

15. Harvesting device according to claim 14, further provided with a motor which is placed on the frame and is connected drivingly to both the conveyor track and a first chassis carrying the frame.

16. Harvesting device according to any one of the foregoing claims, wherein the conveyor track comprises a chain.

17. Harvesting device according to any one of the foregoing claims, provided with two substantially identical conveyor tracks with harvesting bins connected thereto, which conveyor tracks are removed from each other in a horizontal direction transversely of the transport direction and are driveable in circular manner in opposite direction.

18. Harvesting device according to claim 17, wherein the frame forms a gantry which is displaceable over a row of plants, wherein the two conveyor tracks each lie on one side of the gantry.

19. Harvesting device according to claim 17 or 18, when dependent on at least claim 11, wherein each conveyor track has its own crate transport system.

20. Harvesting device according to claim 19, when dependent on at least claim 12, wherein the buffer, the de-stacker, the filling track and the stacker lie substantially in the same vertical plane parallel to the transport direction.

21. Harvesting device according to any one of the foregoing claims, further provided with at least one platform which is mounted on the frame and is configured to carry workers.

22. Harvesting device according to claim 21, wherein the at least one platform is placed within the periphery of the at least one conveyor track.

23. Harvesting device according to any one of the foregoing claims, further provided with displacing means for displacing the harvesting device transversely of the transport direction.

24. Harvesting device according to claim 23, wherein the displacing means comprise a collapsible and extendable second chassis.

25. Harvesting device according to claim 24, wherein the frame is carried by the first chassis and the harvesting device is further provided with lifting means for lifting and lowering the frame relative to the first chassis or second chassis.

26. Harvesting device according to any one of the foregoing claims, further provided with a tarpaulin tensioned above the at least one harvesting bin at an angle to the horizon for the purpose of catching fruit out of reach of the at least one harvesting bin and guiding it to the at least one harvesting bin.

27. Harvesting device according to claim 26, further provided with a ribbon tensioned along the tarpaulin for the purpose of slowing down fruit caught by the tarpaulin.

28. Harvesting device according to any one of the foregoing claims, wherein:

- the harvesting device is also displaceable counter to the transport direction; and

- the at least one conveyor track is driveable in circular manner in two directions.

29. Method for harvesting fruit hanging from a plant, comprising the steps of:

- displacing a harvesting device according to any one of the foregoing claims toward a plant in a transport direction; and

- driving the at least one conveyor track in circular manner, and thereby:

- displacing the at least one harvesting bin to a first position lying close to an underside of the plant;

- holding the at least one harvesting bin in the first position at the same time as shaking the plant so that fruit therefrom falls into the at least one harvesting bin or at the same time as picking and dropping fruit so that it falls into the at least one harvesting bin;

- displacing the at least one harvesting bin to a second position, in which the at least one harvesting bin is removed further from the plant than in the first position and lies higher than in the first position; and

- emptying the at least one harvesting bin in the second position.
