摘要:
A rotatable working device (20) for mounting on the frame (6) of a machine, the device (20) comprising a drive shaft (9) and a number of working elements (10) mounted on the drive shaft, and the machine having bearing supports (7) provided on the frame (6) in which the drive shaft (9) can be rotatably mounted, and in which:
a two part hub assembly (1,2) is provided at at least one end of the drive shaft (9), and which comprises:
a first hub portion (1) having a projecting stub shaft (1.1) intended to be received by a respective bearing support (7) and to be coupled with a drive coupling provided on the machine; and a second hub portion (2) which is connected to said one end of the drive shaft (9) and which is releasably coupled to the first hub portion (1) whereby, in an operating mode of the device, the drive coupling (8) can apply drive input to the shaft (9) via the first and second hub portions (1, 2) when they are coupled together and, upon release of the second hub portion (2) from the first hub portion (1) in a release mode of the device, the drive shaft (9) and working elements (10) mounted thereon can be de-mounted from the machine as a unit.

An agricultural separator comprises a first rotatable member (3) and a second rotatable member (4) rotatable about substantially parallel spaced axes. The first rotatable member (3) carries a plurality of wheels (1) with angularly-spaced resilient fingers (2) and the second rotatable member (4) carries a plurality of corresponding cam members (5). Each cam member 5 has at least one cam surface (6) at its periphery and the rotatable members (3,4) are arranged such that, in use, the cam surface (6) on each cam member (5) engages and squeezes at least one of the resilient fingers (2) of the corresponding wheel (1) to facilitate cleaning of the wheels.
摘要:
An apparatus (10) for providing a fluidized bed (24) to effect the separation of a mixture of articles (58, 60) having at least a first density and a second density that is greater than the first density into separate groups. The apparatus (10) includes an inclined trough (12) which is supplied at an input end (18) with either a fluidization medium, such as sand, or a mixture of articles (58, 60) from which a fluidized bed (24) is formed by forcing gas upwardly through the bottom of the trough and through the fluidization medium or the mixture. In the case where a fluidization medium such as sand is used, the mixture of articles is introduced into the fluidized bed medium so as to be entrained therewith to effect separation as the articles travel in the direction of flow of the fluidized bed medium. Vertical oscillatory movement is imparted to the inclined trough (12) to improve the separation and layering where the mixture of articles is fluidized, or to improve the density uniformity where a fluidization medium such as sand is fluidized as the bed.
摘要:
An agricultural separator comprises three spaced rotatable members (4, 5, 6) each comprising a row of axially-spaced starwheels (9) having angularly-spaced resilient fingers (15, 15′). The spacing (17) between the first and second rotatable members (4, 5) and the spacing between the starwheels (9) thereof is sufficiently small to allow particles of a relatively small size to pass therethrough for return to the ground. The spacing between the second and third rotatable members (5, 6) and/or the spacing between the starwheels (9) of the third rotatable member (6) is sufficiently large to separate out larger objects for removal laterally (7) of the separator. Still larger objects is passed on by the third rotatable member (6) to a trough or bin (8).
摘要:
A debris separating device (200) for separating debris (2) from crops (1) is presented. The debris separating device (200) comprises a receiving end (220) for receiving the collection of objects (5) and an output end (230) arranged vertically below the receiving end (220) for providing objects (5) downstream in a feeding flow (F) of the debris separating device (200). Further to this, the debris separating device (200) comprises a driven closed loop carrier medium (210) arranged between the receiving end and the output end (230). The driven closed loop carrier medium (210) is provided with one or more openings (212) adapted to permit crops (1) to pass there through, and the driven closed loop carrier medium (210) is arranged to provide objects (5) passing there through to the output end (230) of the debris separating device (200).
