CONSTRUCTIVE ARRANGEMENT APPLIED TO GRAIN HARVESTING MACHINE

Abstract

A constructive arrangement applied to a grain harvesting machine reducing the sizes of the bulk carrier and the collecting set, bringing them to measurements which are compatible with the body of the machine, thus enabling transportation next to the machine, with no need to disassemble any parts, having hinges and support arms of the bucket and the support structure of the receiving device provided with hinging devices to reduce their lateral dimensions, those hinging devices being activated by hydraulic cylinders.

Claims

1. A constructive arrangement applied to a grain harvesting machine comprising: (a) a bucket defined by a cubic structure, with a base closure, a top closure a front closure, a rear closure and two side closures; (b) a discharge mouth mounted onto one of the side closures; (c) a first set of hydraulic cylinders having a first stage and a second stage; (d) an articulation mechanism, arranged in parallel to the front closure and to the rear closure, having a triangular structure, comprising: a first bar and a second bar hinged and articulated to each other, and arranged in parallel to the base closure and to the side closure bearing the discharge mouth; a first segmented bar and a second segmented bar hinged and articulated to each other, and arranged in parallel to the base closure and to the side closure bearing the discharge mouth; and joined to the first bar and the second bar in an articulated manner; wherein, the first and second bars and the first and second segmented bars are articulated in response to the actuation of the first stage of the first set of hydraulic cylinders, which articulates the side closure bearing the discharge mouth, and wherein further providing locks applied to the second segmented bars, and locks applied to the front closure and rear closure, maintaining the relative position of the first and second segmented bars, and preventing the articulation of the side closure bearing the discharge mouth, so that, when the second stage of the first set of hydraulic cylinders is activated, an articulation of the bucket occurs.

2. The constructive arrangement applied to a grain harvesting machine according to claim 1, further comprising a collecting device, the collecting device comprising: an internal segment and two external segments, the internal segment hinged to the two external segments at articulated hinging points, each of the external segments having an internal section and an external section; a second set of hydraulic cylinders hinged at one end to the articulated hinging points and hinged at an opposite end to external edges located at the external sections of the two external segments.

DETAILED DESCRIPTION OF THE INVENTION

[0025] As shown in FIGS. 1 to 6, the claimed arrangement has a bucket (1) defined by a cubic structure, with a base closure (2), an upper closure (3), a front closure (4), a rear closure (5) and two side closures (6), and a discharge mouth (7) mounted onto one of the side closures (6). The arrangement also has hinging devices located in parallel to the front and rear closures, the hinging devices formed by a triangular structure constituted by a first bar (8) and a second bar (9) which are hinged to each other, located in parallel to the base closure and to the side closure (6) bearing the discharge mouth (7). The hinged bars are joined, and also hinged, to a first segmented bar (10) and a second segmented bar (11), which are also hinged to each other. Upon an activation of the first stage (12) of the first set of hydraulic cylinders (13), hinging the first and second bars (8 and 9) and the first and second segmented bars (10 and 11) on the side closure bearing the discharge mouth, so to change the bucket measurement between the working and displacement or transport positions. Locks (14) are included and applied to the second segmented bars (11), as well as locks (15) applied to the front closure (4) and rear closure (5), keeping the relative position of the first and second segmented bars (10, 11) and avoiding the side closing where the discharge mouth is located, from hinging, so that, when the second stage (16) of the first set of hydraulic cylinders (13) is activated, the bucket may be hinged.

[0026] As shown in FIGS. 7 to 10, the collecting device (17) is further defined by segmented structures, having a collecting device (17) including an internal segment and two external segments having an internal section and an external section; the internal segment hinged to the two external segments at central hinging points (18), where second set of hydraulic cylinders (19) are hinged at one end, and which shafts are hinged to the external edges (20) of the external sections of the external segments of said collecting device, at an opposite end.
