Abstract
ARRANGEMENT IN GATHERING MOUTH FOR BEAN AND PEANUT HARVESTER, comprising a gathering roll (16) which, rotating at an anticlockwise direction, gathers the branches of bean or peanut that are already pulled out and bunched, throwing them upwards and backward to the dragging roll (37) or above the rolls (55-54) and, afterwards, to the dragging roll (37) that, in turn, leads the gathered product to the press cylinder (23), so that this movement itself makes the land and some other small particles to be removed by the sieve or screen ( 14) of the mouth (9); said press cylinder (23) receives and removes the product from the mouth and lead it to the beating cylinder (28) which, in turn, works in the longitudinal-horizontal direction and its tracking system is axial, thereby allowing to speed up or to delay the flow of the product to be trodden out, carrying it through the screen (27), which works for allowing grains and small particles to pass over, stopping the large particles that are carried to the outlet of straw placed in the right back side of the machine. On said set, the vibrating sieve (26) is placed, which receives the trodden out product together with the small particles, such as straw and land, and, through its long extension, removes the land by an outflow system and allow the product ready for being cleaned by a stream of air (30). The product entirely cleaned is carried to the gutter (31-33) and, from this point on, the chained container lift (34) carries the product entirely cleaned to the bulk section (36).
Description
ARRANGEMENT IN GATHERING MOUTH FOR BEAN AND PEANUT HARVESTER
Field of the Invention The present invention relates generally to farming equipment, and more particularly to harvesters.
Background of the Invention There are currently several machines and agricultural accessories with harvester headers specially designed to gathering the plant material, such as grains, mainly the peanut and the bean, like the Brazilian applications MU 7801088 (BR) of June 8, 1998, MU 7900686 (BR) of March 27, 1999 and MU 7900789 (BR) of May 21, 1999 - all of them designated as ARRANGEMENT IN BEAN AND PEANUT HARVESTER, and P10001647-0 (BR) of April 19, 2000 - HARVESTER SET FOR BRANCHES.
The above harvesters are generally equipped with similar harvester headers and similarly assembled with a movable inlet tunnel with a transversal section slightly rectangular and tapered in the machine longitudinal direction, including a slight backward narrowing, where its rear end is jointly fixed to the structure and, in such a condition, the same tunnel is kept lifted by mechanical means, the latter being a threaded element with manual nut and an adjustment spring for the height of the operation, while, on the lower side, the tunnel has its wall shaped such as a static sieve, also being provided with a wheeling system designed as a supporting guiding roll which, in turn, allows the tunnel or its lower mouth to follow in a lifted way the irregularities of the ground because a gathering roll is transversely assembled with gathering pins along with the header, which moves alternately, the same pins being more exposed on the lower part of the roll while they are more retracted on the upper part and, thus, this retractable effect, with the rotation of the set by the transmission, allows both to gather the branches and to throw them towards the tunnel and, on its sieve, where dragging keeps on going through a dragging conveyor belt, helping the capture of the branches and to drag them over the sieve, throwing them inside a transversally section existing in the front part of the chassis, where a press cylinder is assembled having a embodiment similar to the gathering roll, however, in this case, with a lower number of retractable pins, and its external part also includes an helicoidal conductor, helping to carry the branches to the inlet of another longitudinal section placed over the chassis, the section being internally limited by a vibrating sieve and by a sieve-shaped or by a screen-shaped tunnel, where a beating cylinder with an helicoid with L-shaped pins and paddle are provided inside the screen and above the vibrating sieve, helping to beat the branches and, at the same time, to displace them backwards, where the beating tunnel and the vibrating sieve are interconnected with two different parts: the sieve ends in a right side outlet while the vibrating sieve is connected with an aspirating duct which, in addition to being provided with adjustments of air inlet and of stretcher bearing, is also provided with purifying fan of the tracked material on the top and, further, the sieve also ends in a almost clean grain transversal gathering gutter with a transporting thread that, in turn, ends in a lowering point and, from this point upwards, a chained container lift is developed, whose upper part is provided with a slope backward extension that finally ends in a bulking section existing on the cart, where the entirely cleaned grains are left.
Therefore, it is noted that, in the harvester headers of the above mentioned machines, the crops are gathered by a tunnel which, in the front end, is designed with a gathering roll and, subsequently, the same tunnel is equipped with a conveyor belt to lead the branches to the press cylinder. This system has logically its advantages, but it has been noted that the same header could be improved because its operation by conveyor belt does not reach the aimed effect in the movement of the plant material.
The present disclosure relates specifically to technical and functional improvements specially developed to provide more efficient means for a gathering mouth (herein referred to as a "harvester header") of a harvester of plant material, such as bean, peanut or any other grain, so that the harvester may gather crops which were previously pulled out and bunched, and, after that, the harvester may also make more efficient the entire cleaning process of the plant material by separating them from the disposable parts of the crop.

Summary of the Invention In one aspect, the present disclosure provides a harvester header having a modified tunnel, but keeping the sieve in its lower part.
In another aspect, the present disclosure provides a harvester header in which the conveyor belt is replaced with a rotation intermediate piece for dragging the plant material, so that the same piece may, on one side, to catch the plant material gathered by the press roll and, on the other side, to pull the plant material to the press cylinder. In this condition, the movement of the plant material, besides of being more efficient, has a new technical effect because the rotation piece for dragging can comprise several star-shaped pieces of four curved ends and, thus, a closer handling of the plant material is performed by shaking them in order to be separated from soil and other remainders that are rejected by the sieve.
In yet another aspect, the present disclosure provides a harvester header having a separator assembly that cooperates with the gathering means to disengage at least some plant material from the gathering means once the plant material has been gathered from the ground and moved into the header. The gathering means of the present header, in spite of being like that described in the application P10001647-0 of April 19, entitled harvester set of branches, has been modified with the addition of a separator assembly, which in at least one embodiment comprises curved rules or springs likewise curved among the twisted nails, giving the set a rotative combs shape and, thus, this gathering set, during its operation, has proved to be more efficient when compared to the prior art because, with such an embodiment, the gathering roll is shaped so as to have its diameter or its ordinarily cylindric surface featured by the radially assembled nails, which are in charge of gathering the plant material and of throwing it to the intermediate dragging roll, consequently, the plant material becomes substantially untied on the gathering roll, thereby avoiding the accumulation which eventually could reduce the efficiency of the operation of the gathering roll.

Detailed Description of the Invention The present harvester header is adapted for use in harvesters. In at least one embodiment, the present harvester header is adapted for use in towed harvesters, such as the harvester depicted in Figures 1 and 2. Before getting to the description of the present harvester header, the harvester chassis shown in Figures 1 and 2 will first be described.
This harvester comprises a harvester chassis (1), which is supported on a pair of wheels (2). Chassis (1) has anterior and posterior portions, and a threshing assembly disposed therebetween and generally in section (25) of chassis (1). Threshing assembly comprises a tunnel in the form of a sieve or screen (27), and a beating cylinder (28) disposed within the screen (27). Beating cylinder (28) beats the plant material (R) and, at the same time, dislodges it in the direction of the posterior portion of chassis (1). The threshing assembly is disposed above a vibrating sieve (26), which collects some of the plant material that has fallen through screen (27) of the threshing assembly.
Vibrating sieve (26) also moves, by way of vibrations, some of the plant material that has fallen through screen (27) rearwardly in the direction of the posterior portion of chassis (1). In the posterior portion of chassis (1), screen (27) of the threshing assembly and vibrating sieve (26) are interconnected with two different parts. Screen (27) ends in a right side outlet, while the vibrating sieve (26) is connected with an aspirating duct (29) that, in addition to being provided with air supply adjustments, is also above provided with a purifying fan.
Vibrating sieve (26) also ends in a transversal gathering gutter (31) of almost clean plant material with a transporting thread (32). Transporting thread (32) moves the plant material to a lowering point (33). From this point, the plant material is moved upward in a shaft by way of a chained container lift (34). Container lift (34) dumps the plant material into extension (35), which slopes downwardly to a bulk section (36) in the chassis (1).
In addition, as shown in Figure 2, chassis (1) comprises a press cylinder (23) disposed in an intake area of the anterior portion of chassis (1). Press cylinder (23) can have a plurality of retractable pins, and its external part can also include a helicoid transporter (24), which helps to move the plant material from the anterior portion of chassis (1) to the section (25) of chassis (1) where the threshing assembly is located.
The present harvester header is now described. Reference is first made to Figures 1 and 2, wherein one embodiment of the present harvester header is shown. In these figures, harvester header (9) is disposed at the anterior portion of harvester chassis (1). In this embodiment, the entire harvester can be towed or otherwise moved by a vehicle, such as a tractor, via the harvester header (9). Header (9) can comprise an engaging shaft (3) for this purpose, which can include a universal towing engagement (5).
Engaging shaft (3) can also have a vertical resting base (4). In addition, header (9) can also have a hydraulic system having hydraulic set (7), and means (6) for connecting hydraulic set (7) to a hydraulic source. Means (6) may also provide for connection of header (9) to an external mechanical power source, such as a powered drive shaft. The powered drive shaft can be, for example, a power switch of a tractor. In at least one embodiment, means (6) comprises a header drive for connection with the powered drive shaft.
Furthermore, as shown in Figure 2, means (6) can comprise a duct with internal means for the header drive in the form of a cardan shaft (8). Header (9) can further comprise a transmission system for transferring mechanical power from the external mechanical power source to various subsystems and components of header (9) and chassis (1). The header drive of header (9) can be positioned between the header transmission and the external power source. The transmission (not shown) can comprise one or more belts, chains, pulleys, gears and other kinds of components for the interconnection, rotation and driving of the different movable parts of header (9) and chassis (1).
Harvester header (9) further comprises a header support structure defining an inlet tunnel therethrough for the travel of plant material (R) gathered from the ground to the inlet area of the harvester chassis (1). Header support structure generally has front, rear, upper and lower portions and two opposing and spaced apart outer ends.
At least one supporting wheel (15) is disposed at the front portion of the header support structure for supporting the front portion above the ground, thereby allowing header (9) to follow the irregularities of the ground. In addition, the header support structure is pivotally coupleable to the anterior portion of the harvester chassis (1). As shown in Figure 1, header support structure can be pivotally connected to chassis (1) by way of one or more pivotal connections (10).
The inlet tunnel defined by the header support structure can have a cross section being slightly rectangular and tapered in the front to rear direction, including a slight backward narrowing. Header support structure can be retained relative to means (6) by way of mechanical means (11) and (12). In at least one embodiment, means (11) is in the form of a chain, and means (12) is in the form of an adjustable threaded bolt and nut combination. Means (12) can also comprise an adjustment spring for facilitating the operation height of the harvester header (9).
As shown in Figures 2, 7, and 9, the lower portion of the header support structure located between the front and rear portions comprising a sieve portion (14) for allowing unwanted material separated from the plant material to pass therethrough.
Reference is now made to Figures 2 to 4, 8, and 9. Harvester header (9) comprises gathering means (16) positioned in the front portion of the support structure for gathering the plant material (R) from the ground and moving the plant material into the inlet tunnel toward the rear portion of the header support structure.
Gathering means (16) can be disposed and extend between the outer ends of the header support structure, and be rotatably coupled to the header support structure.
In at least one embodiment, gathering means can be in the form of a gathering roll (16). Having reference to Figure 3, gathering roll (16) can comprise a tubular body (17) and tubular assembling ends (18), these and the first one being crossed by a static shaft (19) with an eccentric intermediate part (20). Shaft (19) can be rotatably coupled to the header support structure. Gathering roll (16) can also comprise a plurality of gathering members extending outwardly relative shaft (19) in a transverse direction relative to the rotational axis of shaft (19), and wherein the gathering members are spaced apart from one another at least in the longitudinal direction of the rotational axis of shaft (19). In addition, gathering members can also be circumferentially spaced-apart from one another relative to the shaft (19) of the gathering means (16). In other words, gathering members can be radially spaced around the rotational axis of shaft (19).
Furthermore, as shown in the Figures, gathering members can be in the form of a plurality of gathering pins (21) distributed along intermediate part (20), which, on one end, are assembled such as connecting rods on the eccentric part of the shaft, while holes existing in the tubular body (17) cross the opposite ends, where said pins move alternately, being more exposed on the lower and upper part of the roll, while in the rear part they are more retracted. Thus this retractable effect, which gradually takes place with the rotation of the set through the transmission (22) (shown in Figure 7), gathers the plant material (R) and throws it towards and into the tunnel defined by the header support structure. As shown in Figure 9, gathering means (16) moves the plant material into the tunnel and towards sieve (14) in the lower portion of the header support structure.
As best shown in Figures 2 and 9, header (9) further comprises first dragging means (37). First dragging means (37) can be located within the header support structure between the gathering means (16) and the rear portion of the header support structure for moving the plant material gathered by the gathering means (16) toward the rear portion of the header support structure. In addition, first dragging means (37) is disposed and extends between the outer ends of the header support structure. First dragging means (37) also comprises a shaft (38) rotatably coupled to the header support structure, and a plurality of dragging portions (43) disposed at spaced-apart locations along the shaft (38). Furthermore, each dragging portion (43) can have a plurality of arms extending in a substantially radial direction from the shaft (38).
As shown in Figures 2 and 9, one or more of the arms of each dragging portion (43) of the first dragging means (37) can be curved about a longitudinal axis of each arm in a direction that is opposite to the direction of rotation of the first dragging means indicated by an arrow in Figure 9. This direction is discussed further below.
Each dragging portion (43) of the first dragging means can have four arms.
In addition, as shown in Figure 9, harvester header (9) can have an untying comb (44) disposed within the header support structure and at the first dragging means (37) for disengaging at least some plant material from the arms of the first dragging means (37) when the arms of the first dragging means are rotated. Untying comb (44) cooperates with the arms of the first dragging means (37) for disengaging at least some plant material from the arms of the first dragging means (37) after the plant material has been dragged by the first dragging means (37).
Untying comb (44) can comprise a plurality of spaced-apart tooth members, the tooth members being interspaced with the dragging portions of the first dragging means (37). In addition, as shown in Figure 9, untying comb (44) can be disposed between the shaft (38) of the first dragging means (37) and the rear portion of the header support structure. Furthermore, untying comb (44) can extend rearwardly and upwardly in the header support structure from the region near or at the shaft (38) of the first dragging means (37).
In addition, as mentioned above, harvester header (9) comprises transmission means for transferring mechanical power from an external mechanical power source to various subsystems and components of header (9). In at least one embodiment, transmission means transfers mechanical power from the header drive to the gathering means (16) to rotate the gathering means for gathering the plant material from the ground and moving the plant material into the inlet tunnel. The transmission means also transfers mechanical power from the header drive to the first dragging means to rotate the first dragging means in a direction so that the arms of the first dragging means (37) move the gathered plant material under the shaft of the first dragging means and toward the rear portion of the header support structure.
The transmission means can be adapted to rotate the gathering means (16) in a direction so that the gathering means (16) moves the gathered plant material over the shaft (19) of the gathering means (16) and into the header support structure.
This direction is indicated by an arrow in Figure 9.
The transmission of one of the embodiments shown in the Figures is now described in more detail. Having reference to Figure 7, shaft (38) can be synchronized with the side transmission (22), where a chain (39) with a stretcher (40) interconnects the gearing (41-42) of the gathering means (16) and of the first dragging means (37), as well as, in the opposite side, as seen in Figure 10, there can also exist a transmission by gearing and chain between the first dragging means (37) and the press cylinder (23) of the harvester chassis (1).
As shown in Figure 9, the lower portion of the header support structure located between the front and rear portions and below the first dragging means (37) can have a curved shape in a direction extending between the front and rear portions of the header support structure and that substantially conforms to a shape of a portion of a lower path of rotation of distal ends of the arms of the first dragging means (37). This portion may also conform to the lower profile of the gathering means (16). In addition, at least a portion of the curved shape of the lower portion of the header support structure can be substantially sinuous. This lower portion of the header support structure is generally the region in which the sieve (14) is disposed, so that the first dragging means (37) drags the plant material over sieve (14) to separate unwanted material from the plant material.
In addition, as can be seen in Figures 3 to 6, 8 and 9, gathering means can be in the form of a gathering roll (16). Gathering roll (16) can comprise several sets of gathering pins (21), where each set can have six radial pins, originating a circle (21 A) of pins. However, each set can have fewer or more than six pins.
Harvester header (9) can also comprise a separator assembly disposed at the gathering means (16) and cooperating with the gathering members of the gathering means for disengaging at least some plant material from the gathering members once the plant material has been moved into the header support structure by the gathering means.
Again, in the embodiments shown in the Figures, gathering members are in the form of pins 21. The separator assembly can comprise a plurality of spaced-apart separator members (45), the separator members being aligned transversely to the rotational axis of the gathering means (16) and distributed lengthwise relative the gathering means. In addition, separator members (45) can be interspaced with the gathering members (21) of the gathering means (16) for disengaging at least some plant material from the gathering members (21).
As best seen in Figure 9, in at least one embodiment, at least a portion of each separator member (45) of the separator assembly can be curved and extend around a portion of the rotational axis of the gathering means (16). Separator members (45) can extend at least from a frontal portion of the gathering means (16) to an upper region of the gathering means (16) to guide the plant material into the header support structure and to disengage at least some plant material from the gathering members (21). As shown in Figure 9, in at least one embodiment, separator members (45) can be substantially U-shaped and extend around gathering means (16) between gathering members (21).
Separator members (45) can be connected to header support structure by way of supports (46), and can be made from, for example, sheet metal.
Separators (45) have been developed to define a front semicircular or U-shaped surface at gathering means (16) and, thus, the plant material slides more easily about gathering means (16) backwards to first dragging means. In addition, separator assembly helps to prevent interlacement and bunching of the plant material around the area of the gathering means (16).
As best shown in Figures 8, 9 and 10, header (9) can comprise height adjustment means for adjusting the position of the front portion of the header support structure relative to the position of the at least one supporting wheel (15), thereby providing for adjustment of the distance between the gathering means (16) and the ground. In at least one embodiment, as shown in the Figures, header (9) can have an intermediate set for the height adjustment (47), comprised by a telescope (48) whose end is interconnected with the supporting structure (49) of the corresponding wheel (15), while the upper end comprises a bearer (50) and spring (51) fastened to the side of header (9), where the set is crossed by a threaded piece (52) with the corresponding handle (53), thereby providing the necessary means to increase and reduce the course of said telescope (48) and, consequently, it is possible to establish an ideal height for the operation of gathering means (16).
Figures 11 to 17 show other embodiments of header (9). In these embodiments, separator members (45') comprise round bars that are curved. In addition, as shown in Figures 13 to 15, each set of pins in gathering means (16) is preferably comprised of eight retractable pins (21).
As best shown in Figure 15, header (9) can comprise one or more additional dragging means. In the embodiment shown in Figure 15, header (9) has a secondary dragging means (54) and a tertiary dragging means (55) both for moving the plant material gathered by the gathering means (16) further toward the rear portion of the header support structure. Secondary (54) and tertiary (55) dragging means are located within the header support structure and can be rotatably coupled to the header support structure. Secondary (54) and tertiary (55) dragging means can be disposed and extend between the outer ends of the header support structure, and can be disposed adjacent the lower portion of the header support structure. Secondary dragging means (54) is positioned between gathering means (16) and first dragging means (37), and tertiary dragging means (55) is positioned between the gathering means (16) and secondary dragging means (54), As shown in Figure 15, in at least one embodiment, secondary dragging means (54) can have a substantially circular cylindrical shape, and tertiary dragging means (55) can have a substantially hexagonal cylindrical shape.
The transmission means of header (9) can be adapted to transfer mechanical power from the header drive to the secondary (54) and tertiary (55) dragging means to rotate the secondary and tertiary dragging means in a direction so that the secondary and tertiary dragging means move the plant material thereover and toward first dragging means (37). Secondary (54) and tertiary (55) dragging means can be synchronized such as is shown in Figures 16 and 17, by a supplementary transmission system (56) assembled in the left and right side of header (9), where the supplementary transmission systems can comprise gears, chains and a belt stretcher, so that secondary (54) and tertiary (55) dragging means, as well as the gathering means (16) and the dragging means (37) may be synchronized with one another and also with the power switch of a tractor (not illustrated).
The operation of the present harvester header is now described. Gathering means (16) can rotated in a direction so that the plant material passes over the rotational axis of the gathering means, gathers the plant material (such as, for example, branches of bean or peanut plants) that are already pulled out and bunched, throwing them upwards and backwards to the dragging means, which include first dragging means (37), and possibly secondary (54) and tertiary (55) dragging means, that, in turn, move the gathered plant material towards the press cylinder (23) at harvester chassis (1). This movement of the plant material causes some of the soil and some other small unwanted particles to be removed from the plant material by the sieve (14) from the header (9).
The operation of the harvester chassis (1) is now described. The press cylinder (23) works to receive and to remove the plant material from the header (9) and lead it to the threshing assembly comprising beating cylinder (28) which, in turn, works in the longitudinal-horizontal direction and its tracking system is axial, thereby allowing to speed up or to delay the flow of the plant material to be trodden out, carrying it through the screen (27). Screen (27), which works for allowing grains and small particles to pass over, stopping the large particles that are carried to the outlet of straw placed in the right back side of chassis (1). On the set, the vibrating sieve (26) is placed, which receives the trodden out plant material together with the small particles, such as fine straw and soil , and, through its long extension, removes the soil by an outflow system and allow the plant material ready for being cleaned by a stream of air (30). The product entirely cleaned is carried to the gutter (31-33) and, from this point on, the chained container lift (34) carries the product entirely cleaned to the bulk section (36).
As it is noted, the improvements introduced in the present harvester, after what has been exposed and illustrated, define a new constructive embodiment, substantially more advantageous than the prior designed machines because, with such changes, the stages of gathering and cleaning the product are more accurately done, i.e., the improvements introduced in the gathering means allows the same to rotate in a contrary direction when compared with the prior art, that is, the plant material is lifted and thrown upwards and backwards, and this does not occur in the prior art, where the dislocation of the plant material is done in a contrary direction and, thus, the amount of dragged land is substantially lower, besides the fact that, simultaneously to the plant material being lifted, the cleaning process is started already, leaving the land that eventually goes along with the plant material. The dragging means (37), being or not assembled with secondary and tertiary dragging means (54-55), also does an additional shake of the plant material, thereby improving the removal of certain particles, mainly the soil, from the gathered plant material. Afterwards, the separation or cleaning process of the grains is like that of the mentioned prior art.

Detailed Description of the Invention The present harvester header is adapted for use in harvesters. In at least one embodiment, the present harvester header is adapted for use in towed harvesters, such as the harvester depicted in Figures 1 and 2. Before getting to the description of the present harvester header, the harvester chassis shown in Figures 1 and 2 will first be described.
This harvester comprises a harvester chassis (1), which is supported on a pair of wheels (2). Chassis (1) has anterior and posterior portions, and a threshing assembly disposed therebetween and generally in section (25) of chassis (1). Threshing assembly comprises a tunnel in the form of a sieve or screen (27), and a beating cylinder (28) disposed within the screen (27). Beating cylinder (28) beats the plant material (R) and, at the same time, dislodges it in the direction of the posterior portion of chassis (1). The threshing assembly is disposed above a vibrating sieve (26), which collects some of the plant material that has fallen through screen (27) of the threshing assembly.
Vibrating sieve (26) also moves, by way of vibrations, some of the plant material that has fallen through screen (27) rearwardly in the direction of the posterior portion of chassis (1). In the posterior portion of chassis (1), screen (27) of the threshing assembly and vibrating sieve (26) are interconnected with two different parts. Screen (27) ends in a right side outlet, while the vibrating sieve (26) is connected with an aspirating duct (29) that, in addition to being provided with air supply adjustments, is also above provided with a purifying fan.
Vibrating sieve (26) also ends in a transversal gathering gutter (31) of almost clean plant material with a transporting thread (32). Transporting thread (32) moves the plant material to a lowering point (33). From this point, the plant material is moved upward in a shaft by way of a chained container lift (34). Container lift (34) dumps the plant material into extension (35), which slopes downwardly to a bulk section (36) in the chassis (1).
In addition, as shown in Figure 2, chassis (1) comprises a press cylinder (23) disposed in an intake area of the anterior portion of chassis (1). Press cylinder (23) can have a plurality of retractable pins, and its external part can also include a helicoid transporter (24), which helps to move the plant material from the anterior portion of chassis (1) to the section (25) of chassis (1) where the threshing assembly is located.
The present harvester header is now described. Reference is first made to Figures 1 and 2, wherein one embodiment of the present harvester header is shown. In these figures, harvester header (9) is disposed at the anterior portion of harvester chassis (1). In this embodiment, the entire harvester can be towed or otherwise moved by a vehicle, such as a tractor, via the harvester header (9). Header (9) can comprise an engaging shaft (3) for this purpose, which can include a universal towing engagement (5).
Engaging shaft (3) can also have a vertical resting base (4). In addition, header (9) can also have a hydraulic system having hydraulic set (7), and means (6) for connecting hydraulic set (7) to a hydraulic source. Means (6) may also provide for connection of header (9) to an external mechanical power source, such as a powered drive shaft. The powered drive shaft can be, for example, a power switch of a tractor. In at least one embodiment, means (6) comprises a header drive for connection with the powered drive shaft.
Furthermore, as shown in Figure 2, means (6) can comprise a duct with internal means for the header drive in the form of a cardan shaft (8). Header (9) can further comprise a transmission system for transferring mechanical power from the external mechanical power source to various subsystems and components of header (9) and chassis (1). The header drive of header (9) can be positioned between the header transmission and the external power source. The transmission (not shown) can comprise one or more belts, chains, pulleys, gears and other kinds of components for the interconnection, rotation and driving of the different movable parts of header (9) and chassis (1).
Harvester header (9) further comprises a header support structure defining an inlet tunnel therethrough for the travel of plant material (R) gathered from the ground to the inlet area of the harvester chassis (1). Header support structure generally has front, rear, upper and lower portions and two opposing and spaced apart outer ends.
At least one supporting wheel (15) is disposed at the front portion of the header support structure for supporting the front portion above the ground, thereby allowing header (9) to follow the irregularities of the ground. In addition, the header support structure is pivotally coupleable to the anterior portion of the harvester chassis (1). As shown in Figure 1, header support structure can be pivotally connected to chassis (1) by way of one or more pivotal connections (10).
The inlet tunnel defined by the header support structure can have a cross section being slightly rectangular and tapered in the front to rear direction, including a slight backward narrowing. Header support structure can be retained relative to means (6) by way of mechanical means (11) and (12). In at least one embodiment, means (11) is in the form of a chain, and means (12) is in the form of an adjustable threaded bolt and nut combination. Means (12) can also comprise an adjustment spring for facilitating the operation height of the harvester header (9).
As shown in Figures 2, 7, and 9, the lower portion of the header support structure located between the front and rear portions comprising a sieve portion (14) for allowing unwanted material separated from the plant material to pass therethrough.
Reference is now made to Figures 2 to 4, 8, and 9. Harvester header (9) comprises gathering means (16) positioned in the front portion of the support structure for gathering the plant material (R) from the ground and moving the plant material into the inlet tunnel toward the rear portion of the header support structure.
Gathering means (16) can be disposed and extend between the outer ends of the header support structure, and be rotatably coupled to the header support structure.
In at least one embodiment, gathering means can be in the form of a gathering roll (16). Having reference to Figure 3, gathering roll (16) can comprise a tubular body (17) and tubular assembling ends (18), these and the first one being crossed by a static shaft (19) with an eccentric intermediate part (20). Shaft (19) can be rotatably coupled to the header support structure. Gathering roll (16) can also comprise a plurality of gathering members extending outwardly relative shaft (19) in a transverse direction relative to the rotational axis of shaft (19), and wherein the gathering members are spaced apart from one another at least in the longitudinal direction of the rotational axis of shaft (19). In addition, gathering members can also be circumferentially spaced-apart from one another relative to the shaft (19) of the gathering means (16). In other words, gathering members can be radially spaced around the rotational axis of shaft (19).
Furthermore, as shown in the Figures, gathering members can be in the form of a plurality of gathering pins (21) distributed along intermediate part (20), which, on one end, are assembled such as connecting rods on the eccentric part of the shaft, while holes existing in the tubular body (17) cross the opposite ends, where said pins move alternately, being more exposed on the lower and upper part of the roll, while in the rear part they are more retracted. Thus this retractable effect, which gradually takes place with the rotation of the set through the transmission (22) (shown in Figure 7), gathers the plant material (R) and throws it towards and into the tunnel defined by the header support structure. As shown in Figure 9, gathering means (16) moves the plant material into the tunnel and towards sieve (14) in the lower portion of the header support structure.
As best shown in Figures 2 and 9, header (9) further comprises first dragging means (37). First dragging means (37) can be located within the header support structure between the gathering means (16) and the rear portion of the header support structure for moving the plant material gathered by the gathering means (16) toward the rear portion of the header support structure. In addition, first dragging means (37) is disposed and extends between the outer ends of the header support structure. First dragging means (37) also comprises a shaft (38) rotatably coupled to the header support structure, and a plurality of dragging portions (43) disposed at spaced-apart locations along the shaft (38). Furthermore, each dragging portion (43) can have a plurality of arms extending in a substantially radial direction from the shaft (38).
As shown in Figures 2 and 9, one or more of the arms of each dragging portion (43) of the first dragging means (37) can be curved about a longitudinal axis of each arm in a direction that is opposite to the direction of rotation of the first dragging means indicated by an arrow in Figure 9. This direction is discussed further below.
Each dragging portion (43) of the first dragging means can have four arms.
In addition, as shown in Figure 9, harvester header (9) can have an untying comb (44) disposed within the header support structure and at the first dragging means (37) for disengaging at least some plant material from the arms of the first dragging means (37) when the arms of the first dragging means are rotated. Untying comb (44) cooperates with the arms of the first dragging means (37) for disengaging at least some plant material from the arms of the first dragging means (37) after the plant material has been dragged by the first dragging means (37).
Untying comb (44) can comprise a plurality of spaced-apart tooth members, the tooth members being interspaced with the dragging portions of the first dragging means (37). In addition, as shown in Figure 9, untying comb (44) can be disposed between the shaft (38) of the first dragging means (37) and the rear portion of the header support structure. Furthermore, untying comb (44) can extend rearwardly and upwardly in the header support structure from the region near or at the shaft (38) of the first dragging means (37).
In addition, as mentioned above, harvester header (9) comprises transmission means for transferring mechanical power from an external mechanical power source to various subsystems and components of header (9). In at least one embodiment, transmission means transfers mechanical power from the header drive to the gathering means (16) to rotate the gathering means for gathering the plant material from the ground and moving the plant material into the inlet tunnel. The transmission means also transfers mechanical power from the header drive to the first dragging means to rotate the first dragging means in a direction so that the arms of the first dragging means (37) move the gathered plant material under the shaft of the first dragging means and toward the rear portion of the header support structure.
The transmission means can be adapted to rotate the gathering means (16) in a direction so that the gathering means (16) moves the gathered plant material over the shaft (19) of the gathering means (16) and into the header support structure.
This direction is indicated by an arrow in Figure 9.
The transmission of one of the embodiments shown in the Figures is now described in more detail. Having reference to Figure 7, shaft (38) can be synchronized with the side transmission (22), where a chain (39) with a stretcher (40) interconnects the gearing (41-42) of the gathering means (16) and of the first dragging means (37), as well as, in the opposite side, as seen in Figure 10, there can also exist a transmission by gearing and chain between the first dragging means (37) and the press cylinder (23) of the harvester chassis (1).
As shown in Figure 9, the lower portion of the header support structure located between the front and rear portions and below the first dragging means (37) can have a curved shape in a direction extending between the front and rear portions of the header support structure and that substantially conforms to a shape of a portion of a lower path of rotation of distal ends of the arms of the first dragging means (37). This portion may also conform to the lower profile of the gathering means (16). In addition, at least a portion of the curved shape of the lower portion of the header support structure can be substantially sinuous. This lower portion of the header support structure is generally the region in which the sieve (14) is disposed, so that the first dragging means (37) drags the plant material over sieve (14) to separate unwanted material from the plant material.
In addition, as can be seen in Figures 3 to 6, 8 and 9, gathering means can be in the form of a gathering roll (16). Gathering roll (16) can comprise several sets of gathering pins (21), where each set can have six radial pins, originating a circle (21 A) of pins. However, each set can have fewer or more than six pins.
Harvester header (9) can also comprise a separator assembly disposed at the gathering means (16) and cooperating with the gathering members of the gathering means for disengaging at least some plant material from the gathering members once the plant material has been moved into the header support structure by the gathering means.
Again, in the embodiments shown in the Figures, gathering members are in the form of pins 21. The separator assembly can comprise a plurality of spaced-apart separator members (45), the separator members being aligned transversely to the rotational axis of the gathering means (16) and distributed lengthwise relative the gathering means. In addition, separator members (45) can be interspaced with the gathering members (21) of the gathering means (16) for disengaging at least some plant material from the gathering members (21).
As best seen in Figure 9, in at least one embodiment, at least a portion of each separator member (45) of the separator assembly can be curved and extend around a portion of the rotational axis of the gathering means (16). Separator members (45) can extend at least from a frontal portion of the gathering means (16) to an upper region of the gathering means (16) to guide the plant material into the header support structure and to disengage at least some plant material from the gathering members (21). As shown in Figure 9, in at least one embodiment, separator members (45) can be substantially U-shaped and extend around gathering means (16) between gathering members (21).
Separator members (45) can be connected to header support structure by way of supports (46), and can be made from, for example, sheet metal.
Separators (45) have been developed to define a front semicircular or U-shaped surface at gathering means (16) and, thus, the plant material slides more easily about gathering means (16) backwards to first dragging means. In addition, separator assembly helps to prevent interlacement and bunching of the plant material around the area of the gathering means (16).
As best shown in Figures 8, 9 and 10, header (9) can comprise height adjustment means for adjusting the position of the front portion of the header support structure relative to the position of the at least one supporting wheel (15), thereby providing for adjustment of the distance between the gathering means (16) and the ground. In at least one embodiment, as shown in the Figures, header (9) can have an intermediate set for the height adjustment (47), comprised by a telescope (48) whose end is interconnected with the supporting structure (49) of the corresponding wheel (15), while the upper end comprises a bearer (50) and spring (51) fastened to the side of header (9), where the set is crossed by a threaded piece (52) with the corresponding handle (53), thereby providing the necessary means to increase and reduce the course of said telescope (48) and, consequently, it is possible to establish an ideal height for the operation of gathering means (16).
Figures 11 to 17 show other embodiments of header (9). In these embodiments, separator members (45') comprise round bars that are curved. In addition, as shown in Figures 13 to 15, each set of pins in gathering means (16) is preferably comprised of eight retractable pins (21).
As best shown in Figure 15, header (9) can comprise one or more additional dragging means. In the embodiment shown in Figure 15, header (9) has a secondary dragging means (54) and a tertiary dragging means (55) both for moving the plant material gathered by the gathering means (16) further toward the rear portion of the header support structure. Secondary (54) and tertiary (55) dragging means are located within the header support structure and can be rotatably coupled to the header support structure. Secondary (54) and tertiary (55) dragging means can be disposed and extend between the outer ends of the header support structure, and can be disposed adjacent the lower portion of the header support structure. Secondary dragging means (54) is positioned between gathering means (16) and first dragging means (37), and tertiary dragging means (55) is positioned between the gathering means (16) and secondary dragging means (54), As shown in Figure 15, in at least one embodiment, secondary dragging means (54) can have a substantially circular cylindrical shape, and tertiary dragging means (55) can have a substantially hexagonal cylindrical shape.
The transmission means of header (9) can be adapted to transfer mechanical power from the header drive to the secondary (54) and tertiary (55) dragging means to rotate the secondary and tertiary dragging means in a direction so that the secondary and tertiary dragging means move the plant material thereover and toward first dragging means (37). Secondary (54) and tertiary (55) dragging means can be synchronized such as is shown in Figures 16 and 17, by a supplementary transmission system (56) assembled in the left and right side of header (9), where the supplementary transmission systems can comprise gears, chains and a belt stretcher, so that secondary (54) and tertiary (55) dragging means, as well as the gathering means (16) and the dragging means (37) may be synchronized with one another and also with the power switch of a tractor (not illustrated).
The operation of the present harvester header is now described. Gathering means (16) can rotated in a direction so that the plant material passes over the rotational axis of the gathering means, gathers the plant material (such as, for example, branches of bean or peanut plants) that are already pulled out and bunched, throwing them upwards and backwards to the dragging means, which include first dragging means (37), and possibly secondary (54) and tertiary (55) dragging means, that, in turn, move the gathered plant material towards the press cylinder (23) at harvester chassis (1). This movement of the plant material causes some of the soil and some other small unwanted particles to be removed from the plant material by the sieve (14) from the header (9).
The operation of the harvester chassis (1) is now described. The press cylinder (23) works to receive and to remove the plant material from the header (9) and lead it to the threshing assembly comprising beating cylinder (28) which, in turn, works in the longitudinal-horizontal direction and its tracking system is axial, thereby allowing to speed up or to delay the flow of the plant material to be trodden out, carrying it through the screen (27). Screen (27), which works for allowing grains and small particles to pass over, stopping the large particles that are carried to the outlet of straw placed in the right back side of chassis (1). On the set, the vibrating sieve (26) is placed, which receives the trodden out plant material together with the small particles, such as fine straw and soil , and, through its long extension, removes the soil by an outflow system and allow the plant material ready for being cleaned by a stream of air (30). The product entirely cleaned is carried to the gutter (31-33) and, from this point on, the chained container lift (34) carries the product entirely cleaned to the bulk section (36).
As it is noted, the improvements introduced in the present harvester, after what has been exposed and illustrated, define a new constructive embodiment, substantially more advantageous than the prior designed machines because, with such changes, the stages of gathering and cleaning the product are more accurately done, i.e., the improvements introduced in the gathering means allows the same to rotate in a contrary direction when compared with the prior art, that is, the plant material is lifted and thrown upwards and backwards, and this does not occur in the prior art, where the dislocation of the plant material is done in a contrary direction and, thus, the amount of dragged land is substantially lower, besides the fact that, simultaneously to the plant material being lifted, the cleaning process is started already, leaving the land that eventually goes along with the plant material. The dragging means (37), being or not assembled with secondary and tertiary dragging means (54-55), also does an additional shake of the plant material, thereby improving the removal of certain particles, mainly the soil, from the gathered plant material. Afterwards, the separation or cleaning process of the grains is like that of the mentioned prior art.
