DETAILED DESCRIPTION

[0057] The invention will be understood from the following detailed description of embodiments, which are meant to be descriptive and not limiting. For the sake of brevity, some well-known features, methods, systems, procedures, components, circuits, and so on, are not described in detail.

[0058] FIG. 2 schematically illustrates a sabra fruit harvesting machine at work, according to one embodiment of the invention.

[0059] The harvesting machine, which is marked herein by reference numeral 100, comprises a sealed container 12 for fruit collection; a flexible tube 14 connected to the sealed container 12, wherein the inlet 22 of the suction tube is several millimeters larger than the diameter of a fruit in order to allow “swallowing” of the fruit into the tube.

[0060] Vacuum pump connected to the sealed container 12 draws the air of flexible tube 14 into the sealed container 12 thereby pulling a fruit placed at the inlet of the tube into the sealed container 12, where it is accumulated.

[0061] A user approaches the inlet 22 of flexible tube 14 to a sabra fruit 11, and cuts with a cutting device 27, such as a knife or an oriented device, the fruit at the location 21 where the sabra fruit 11 connects to the sabra plant 10. Due to the suction, the fruit 10 is drawn into the sealed container 12, where it is stored.

[0062] The suction mechanism, i.e., the vacuum pump and the sealed container, are placed on a vehicle 28. A ladder 26 is installed on the vehicle 28. The user that harvests the fruits stands on the ladder 26, while another user (not illustrated) drives the vehicle 28.

[0063] FIG. 3 schematically illustrates a sabra fruit harvesting machine 100, according to one embodiment of the invention.

[0064] FIG. 4 is a zoomed view thereof.

[0065] The machine comprises vacuum pump 13 that sucks air from a flexible tube 14 through a sealed container 12 in which the collected fruits are stored. Thus, by placing a fruit at the inlet 22 of the flexible tube 14, it is sucked into the sealed container 12.

[0066] Reference numeral 15 denotes a door of the sealed container 12. Tube 18 connects the vacuum pump 13 to the sealed container 12.

[0067] This mechanism is placed on a vehicle 28.

[0068] The vehicle also comprises a ladder, which has two adjusting abilities: The ladder can be elongated (part 26b can be shifted with reference to part 26a of the ladder), and additionally its tilt is also adjustable by changing the angle along its axis 30.

[0069] Platform 25 is used to place thereon filled and empty fruit boxes, tools, etc.

[0070] FIG. 5 schematically illustrates a sabra fruit harvesting machine 100 which further details the operation of the machine, according to one embodiment of the invention.

[0071] In this figure, the ladder expands by shifting part 26b of the ladder upwards, with reference to part 26a of the ladder.

[0072] In addition, the door 15 of the sealed container 12 is open.

[0073] FIG. 6 schematically illustrates a sucking mechanism of a sabra fruit harvesting machine 100, according to one embodiment of the invention.

[0074] The mechanism comprising a vacuum pump 13, which is connected via tube 18 to a sealed container 12, used for collecting fruits. To the sealed container 12 is connected a flexible tube 14. The inlet to flexible tube 14 is marked herein by reference numeral 22.

[0075] The vacuum pump 13 draws air through the inlet 22 of flexible tube 14. Upon placing a fruit 11 at the inlet 22 of flexible tube 14 and disconnecting the fruit from the plant, it is sucked into the sealed container 12. On its way, fruit 11 meets barrier 19, which stops and softens its fall, and directs its fall into basket 16, which is placed into the sealed container 12.

[0076] Once in a while, the collecting basket 16 is taken out, and an empty basket 16 replaces it.

[0077] The pumped air enters into the vacuum pump 13 via tube 18, and exits from the vacuum pump via outlet 23 thereof.

[0078] Reference numeral 29 denotes a vacuum released valve. This is useful for allowing easy opening of door 15. More particularly, the valve eliminates the sealing of the sealed container by generating an open aperture in the sealed container.

[0079] FIGS. 7a and 7b demonstrate the action of the ladder, according to one embodiment of the invention.

[0080] In FIG. 7a part 26b of the ladder moves upwards, thereby expending the length of the ladder.

[0081] In FIG. 7b part 26a of the ladder is vertical, while in FIG. 7a it is inclined. Thus, a user can adjust both, the height of the ladder and its inclination, thereby allowing placing the ladder in such a way that his work will be eased.

[0082] FIG. 8 schematically illustrates a fruit cutting device, according to one embodiment of the invention.

[0083] The cutting device, which is marked herein by reference numeral 27, comprises a cutting tool 32 (such as scissors, a shutter, a rotating blade, etc.) and an activation element 31 such as a button (in the case the mechanism is electric), a lever (in the mechanism is mechanical), etc. Thus, a user places the fruit into the cutting device 27, presses the activation element 31, and the cutting tool 32 cuts the fruit from the plant.

[0084] The invention eases the physical harvesting work, provides easy access to fruits to be harvested, diminishes the fruits depreciation, un-necessitates the need to carry a ladder and a pail, allows to concentrate “large” amounts of fruits on the platform of the vehicle, and transporting it to the concentration site. In particular, when it comes to sabra, it helps a worker to avoid contacting with sabra thorns.

[0085] Despite of the fact that the examples herein refer to sabra, it should be noted that the same mechanism can also be implemented for harvesting apples, plums, peaches, oranges, clementine, lemons, Chinese oranges, tomatoes, peppers, strawberries, olives, and other, whether they comprise a stalk or not.

[0086] These benefits are essential since there is a short time to harvest the fruits and send them to the market. If the fruits are not shipped on time, their shelf life is shortened, which means damage to the farmer.
