  • Patent number: 8968065
    Abstract: A combine harvester comprises a separating apparatus arranged to receive a threshed crop stream and convey rearwardly. The separating apparatus comprises a grate for allowing grain and chaff to fall onto an underlying separator pan, the separator pan being driven in an oscillating manner to convey a grain/chaff stream forwardly for delivery to a cleaning unit. The separator pan comprises a first portion and a second portion disposed forwardly of the first portion. A rear edge of the second portion is releasably attached to a front edge of the first portion, the second portion being pivotable around a forward mounting around a transverse axis between an operating position in which the second portion is attached to the first portion forming a continuous pan surface, and a lowered position in which the second portion is detached from the first portion giving maintenance access to the underside of the separating apparatus.

  • Patent number: 8708153
    Abstract: A grape processing apparatus and method is described and which includes a screen, a cleated conveyor belt with a bottom flight and which is spaced from the screen, and a source of bunches of grapes which have associated stems, and which are fed into a predetermined space between the bottom flight of the cleated conveyor belt and the screen, and wherein the bunches of grapes move along the screen in a rolling and tumbling motion to separate the individual grapes from the associated stems, and wherein the individual grapes are collected thereafter.

  • Patent number: 6238285
    Abstract: An agricultural harvesting machine having a threshing and separating mechanism for threshing and separating crop material; and cleaning mechanisms for cleaning the threshed and separated crop material. The cleaning mechanism comprising: a grain pan for receiving threshed and separated crop material and transporting the latter rearwardly; and an upper and lower sieves installed behind the grain pan and operable to receive the material from the grain pan and move it through and along. At least one portion of the grain pan is inclined in a sideways direction for sideways movement of the threshed and separated crop material while it is being transported rearwardly towards the sieve. This inclination spreads out the surplus of crop material supplied to one longitudinal section of the grain pan and delivers it in an even pattern to the front section of the upper sieve.

  • Patent number: 6012276
    Abstract: A harvester (10) includes a separator (22) to help separate unwanted plant material from a crop. Separator (22) includes a series of paddles (46) which are rotated in unison by a drive system (50). The crop, which will often comprise a vine or tree crop, and which will ideally comprise raisins (14), falls between rotating paddles (46). Plant materials, such as cane (60), is transported by the tops of the rotating paddles from over cane separator (22).

  • Patent number: 5791986
    Abstract: The invention provides an improved ripple pan which compensates for the over-deposition of threshed grain onto the outer portions of the grain pan by channeling the grain to the center of the pan. The pan has a central section with ripples that are perpendicular to the flow of the grain, and two outer sections with outer edges that are elevated above the central section. The ripples on the two outer sections are biased such that the outer edges of the ripples are located rearward of the inner edges of the ripples. An alternate embodiment of this invention solves the problem of excessive grain deposition in the central section of the ripple pan. This embodiment has two outer sections configured similarly to the first embodiment and a central section with a center peak which slopes downward on either side of the peak to the inner edges of the outer sections.
