A fruit or vegetable harvesting system, comprising: - a transport system for transferring fruits or vegetables from a harvesting point to an unloading point on a conveyor; - at least one support platform for an operator, the support platform defining a harvesting point for the fruit or vegetables; - a conveyor suitable to receive the fruit or vegetables transferred from the transport system; wherein the transport system comprises a plurality of transport modules connected to one another so as to form a closed chain, where each transport module is provided with, or jointly forms with one or more adjacent transport modules, support means configured to keep a single fruit or vegetable or several fruits or vegetables in a stable position without mutual contact, wherein each transport module comprises a module body with axial symmetry extending along a module axis defining along said module axis a spherical head and a pair of arms firmly connected to the spherical head, where the spherical head is crossed transversely to the module axis by a through head opening forming, on the outer surface of the spherical head, opposite eyelets with a prevalent extension in the direction of the module axis, and where said arms diverge from the spherical head so as to form corresponding distal arm portions, which are mutually spaced apart so as to form therebetween a head seat, which accommodates the spherical head of an adjacent transport module, the distal arm portions being connected by a connection pin passing through the through head opening, so that the arms of each transport module are free to rotate with respect to the spherical head of the transport module to which they are connected, both about the axis of the connection pin and about a head axis passing through the center of the spherical head and orthogonal to the axis of the connection pin, the transport system further comprising motorized movement means and guide means for the chain along a predetermined ring path; wherein the harvesting system is characterized in that the closed chain forms a portion of the forward path, which directly connects the harvesting point to the conveyor, so that each fruit or vegetable collected is transferred from the harvesting point to the conveyor without being moved from the position thereof defined by the support means. - a transport system for transferring fruits or vegetables from a harvesting point to an unloading point on a conveyor; - at least one support platform for an operator, the support platform defining a harvesting point for the fruit or vegetables; - a conveyor suitable to receive the fruit or vegetables transferred from the transport system; wherein the transport system comprises a plurality of transport modules connected to one another so as to form a closed chain, where each transport module is provided with, or jointly forms with one or more adjacent transport modules, support means configured to keep a single fruit or vegetable or several fruits or vegetables in a stable position without mutual contact, wherein each transport module comprises a module body with axial symmetry extending along a module axis defining along said module axis a spherical head and a pair of arms firmly connected to the spherical head, where the spherical head is crossed transversely to the module axis by a through head opening forming, on the outer surface of the spherical head, opposite eyelets with a prevalent extension in the direction of the module axis, and where said arms diverge from the spherical head so as to form corresponding distal arm portions, which are mutually spaced apart so as to form therebetween a head seat, which accommodates the spherical head of an adjacent transport module, the distal arm portions being connected by a connection pin passing through the through head opening, so that the arms of each transport module are free to rotate with respect to the spherical head of the transport module to which they are connected, both about the axis of the connection pin and about a head axis passing through the center of the spherical head and orthogonal to the axis of the connection pin, the transport system further comprising motorized movement means and guide means for the chain along a predetermined ring path; wherein the harvesting system is characterized in that the closed chain forms a portion of the forward path, which directly connects the harvesting point to the conveyor, so that each fruit or vegetable collected is transferred from the harvesting point to the conveyor without being moved from the position thereof defined by the support means.
