Description

Harvester and row unit and separator thereof

Technical Field

The present disclosure relates to the field of agricultural harvesters, in particular, the present disclosure relates to harvesters and row units and dividers thereof.

Background

Combine harvesters typically have a divider, also commonly referred to as a nose, for guiding crop stalks up to an ear separation chamber that includes an ear pick roller and an ear pick plate. The harvested crop is then transported to the interior of the harvester for subsequent processing.

During a harvesting operation, when the header is properly aligned with the rows of crop stalks, a pair of dividers straddle the crop stalks being harvested in each row, and the ears of the crop are directed to the snapping rolls and snapping plates, generally without accident, to be stripped from the stalks. However, it is not uncommon for the row of dividers and crop stalks to become misaligned as the combine traverses the field. The misalignment of the separator and the row of crop stalks means that the row of stalks is not adequately positioned between a pair of adjacent separators. When this occurs, the divider may not properly contact the crop stalks and the combine may not pick some or all of the crop from the stalks. This is due at least in part to the construction of conventional dividers. Typical dividers include vertical sidewall surfaces and/or wide planar bottom ends, which result in severe bending of the divider, potentially shearing off stalks that are misaligned with respect to the divider. Thus, a portion of the valuable ear is not stripped from the stalk, but is left in the field, which results in less than optimal crop harvesting.

Accordingly, there remains a need for a combine harvester having the ability to prevent crop loss at the corn header location.

The divider, row unit and harvester according to the present disclosure will be described below with reference to the accompanying drawings. A harvester according to the present disclosure (not shown in the figures) has a header 100 for harvesting crops, as shown in fig. 5-7. The header 100 is provided at a front end thereof with a row unit 200, and the row unit 200 includes a series of dividers 300 arranged side by side. In one embodiment, the dividers 300 may be arranged parallel to and equally spaced from each other as shown, or may be otherwise arranged as desired.

The dividers 300 may be mounted to the header 100 independently of one another and may pivot relative to the header 100. For example, as shown in fig. 7, which shows one divider 300 pivoted upward to be substantially upright, the other dividers 300 remain substantially parallel to the ground. The number of dividers 300 can be selected as desired.

The divider 300 according to the present disclosure will be described in detail below with reference to fig. 1-4. As shown, the divider 300 may have a generally semi-circular cone shape, i.e., a shape that is half of the cone after it is cut in the longitudinal direction. Of course, it will be understood by those skilled in the art that the divider 300 may take any other suitable shape, such as a half pyramid, etc.

The divider 300 includes a front end 310, a rear end 320, and a divider body 330 extending between the front end 310 and the rear end 320. The front end 310 is the tip portion of the cone that faces forward in the direction of travel of the harvester, and the rear end 320 is the bottom portion of the cone that faces rearward in the direction of the form of the harvester. As such, divider 300 generally tapers from rear end 320 to front end 310. For convenience of the subsequent description, the direction from the front end portion 310 to the rear end portion 320 is defined as the length direction of the separator 300, i.e., the left-right direction in the page of fig. 1, the width direction of the separator 300 is the up-down direction in the page of fig. 1, and the height direction of the separator 300 is the direction perpendicular to the page of fig. 1.

During operation of the divider 300, the divider 300 is generally parallel to the ground with its front end 310, divider body 330 and rear end 320 arranged along the direction of travel of the harvester so that crop can travel along the gaps between adjacent dividers 300 of the row units 200 into the header 100 as the harvester travels in the field. As shown in fig. 7, dividers 300 may be independently pivoted off the ground, for example, to facilitate maintenance work.

The separator body 330 may be made of a material, such as sheet, such that at least a majority of its area has a substantially uniform wall thickness. A hollow chamber 301 is formed within the divider 300 according to the present disclosure, and the hollow chamber 301 may be collectively defined by the front end 310, the rear end 320, and the divider body 330. The side of the hollow chamber 301 facing the ground during operation of the divider 300 is open to reduce weight and cost. The side of the hollow chamber 301 may be completely open or partially open.

The hollow cavity 301 may advantageously be used to house functional components, such as various types of sensors. Due to the presence of the openings, these functional components can act directly facing the ground. In one embodiment, a height sensor (not shown in the figures) may be arranged in the hollow chamber 301, which may be configured to detect the height of the divider 300 relative to the ground during operation of the divider 300.

Due to the presence of the openings, the sides of divider 300 are rimmed near the ground, as shown by dashed lines 302 in fig. 1-3. As can be clearly seen in fig. 1 and 2, the edge extends conically from the rear end 320 to the front end 310. During operation of the dividers 300, crop enters the gaps between adjacent dividers 300 from the front end 310 and travels toward the rear end 320. If a crop approaches the front end 310 as it enters the gap (i.e., if the crop is in a row that is offset from the divider), the crop will be pushed in a lateral direction by the edge 302 as it travels toward the rear end 320, causing the crop to lean to both sides and no longer remain upright. As such, the crop enters at an oblique orientation as it enters the header 100, which is detrimental to subsequent operations.

To avoid or reduce this occurrence, the divider body 330 of the divider 300 according to the present disclosure includes a recessed cut-out 340. The cut-out portion 340 may be formed by, for example, cutting both sides of the separator 300 from the front end portion 310 to the rear end portion 320 such that the edge of the formed cut-out portion 340 extends from the front end portion 310 to the rear end portion 320 and is recessed in the height direction and the width direction of the separator 300. As shown in fig. 3, the edge of the cut-out portion 340 formed after cutting is recessed in the height direction and the width direction with respect to the edge 302 before cutting. Generally, both side edges of the separator 300 are cut to form the cut-outs 340, i.e., the separator body 330 includes both left and right cut-outs 340. Preferably, the edges of the left and right cut-outs 340 have the same configuration, i.e., the edges of the two cut-outs 340 are symmetrically arranged with respect to the length direction of the separator 300. Therefore, in the following description, one cutting portion 340 is described as an example.

As described above, the cut-out portions 340 are recessed in the height direction and the width direction of the separator 300, which results in a reduction in the width direction of the portion of the separator body 330 having the cut-out portions 340, as compared with the case without the cut-out portions 340. As best shown in fig. 1-2, the width of the portion where the cut-out 340 is located is significantly less than the width of the edge 302. Due to this reduction in width, the crop, even near the front end 310, when entering the gap between adjacent dividers 300, maintains as vertical an orientation as possible as it travels toward the rear end 320, facilitating subsequent operations.

The cutout portion 340 may be configured to reduce the width of the divider body 330 in the width direction according to the actual application needs. For example, the cut-out 340 may reduce the width of the divider body 330 by 5% to 50%, preferably by 10% to 40%, such as by about 20% or about 30%, as compared to the width when not cut-out (i.e., the width of the edge 302 in the width direction).

The reduced width configuration of the cut-out 340 may be achieved in a variety of ways, some of which are described below. It will be understood by those skilled in the art that the cut-out portion of the separator according to the present disclosure is not limited thereto, and various modifications and variations may be made thereto as long as they can be used to reduce the width of the separator in the width direction without departing from the spirit and scope of the present disclosure.

The edge of the cut-out 340 may include a first section 341 and a second section 342, the first section 341 extending from the front end 310 towards the rear end 320, the second section 342 extending from the first section 341 to the rear end 320. The first section 341 and the second section 342 may be two consecutive sections with a smooth transition between them.

The first section 341 may extend generally linearly, for example, as shown in fig. 1 and 2, the first section 341 may extend linearly in a top view and a bottom view of the separator 300, and the first section 341 may extend linearly in a front view of the separator 300 shown in fig. 3. The second section 342 may extend curvilinearly, for example, as shown in fig. 3, the second section 342 extends from the first section 341 to the rear end 320 along a substantially circular arc shape. The second section 342 may extend in various patterns of curves, for example it may extend approximately a quarter of a circle, or it may extend in a curve made up of multiple arcs having different radii. In one embodiment, the curve along which the second section 342 extends may also partially include a straight line portion, for example, a section of the second section 342 near the rear end 320 may be a straight line portion.

In one embodiment, the first section 341 may extend a length that is longer than the second section 342, such that the first section 341 extends a majority of the length of the divider body 330 in the length direction of the divider 300, e.g., the first section 341 may extend to proximate the rear end 320, as shown in fig. 3. In this case, the width of most of the area of the divider body 330 in the length direction can be reduced, so that the crop can still maintain a substantially vertical orientation when traveling to the rear end 320 of the divider 300. The first section 341 may extend 1.5 to 3 times, for example, may be about 2 times the length that the second section 342 extends.

The cut-out 340 may be provided at an edge thereof with a reinforcing member 350. The reinforcing member 350 may surround the edge of the cut-out 340 and be fixed thereto by fastening means such as bolts, welding, etc. The reinforcement member 350 may be made of, for example, a metal sheet, and extend along the entire edge of the cut-away portion 340, or along a partial edge of the cut-away portion 340, to reinforce the structural strength of the cut-away portion 340, preventing the separator body 330 from being deformed, such as bent, during the operation of the separator 300.

In the case where the edge of the cut-out portion 340 includes the first and second sections 341 and 342, the reinforcement member 350 includes the first and second reinforcement members 351 and 352, respectively. The first reinforcement member 351 is fixed to the first section 341, and the second reinforcement member 352 is fixed to the second section 342. The first and second reinforcing members 351 and 352 may be integrally formed or may be separately formed.

The divider 300 is provided with a securing portion on the rear end portion 320, and preferably with securing portions 361 on opposite sides of the rear end portion 320, respectively, as shown in fig. 1-4. The divider 300 is secured to the header 100 of the harvester by the securing portion 361, as shown in fig. 5-7. The fixing portion 361 may be in the form of a bolt hole or a pin hole, for example, whereby the divider 300 is fixed to the header 200 by a bolt or a pin.

A support 362 is provided at a position of the separator body 330 near the rear end 320, and the support 362 may be substantially centrally provided in the hollow chamber 301 in the width direction, as shown in fig. 2. The support portion 362 may be supported on the header 100 such that the header 100 may support the divider 300 when the divider 300 is fixed to the header 100 of the harvester by the fixing portion 361.

The separator body 330 of the separator 300 according to the present disclosure may be further provided with a reinforcing structure so as to reinforce the strength of the separator body. In the illustrated embodiment, these reinforcing structures are located within the hollow chamber 301, but it will be understood by those skilled in the art that such reinforcing structures may also be located outside of the hollow chamber 301. The reinforcing structure according to the present disclosure mainly includes a support reinforcing structure 370 and a pressure reinforcing structure 380.

As shown in fig. 2, the support reinforcement structure 370 is located within the hollow chamber 301 at a substantially middle position of the divider body 330. The support reinforcement structure 370 is primarily used to prevent a buckling condition that may occur during operation of the divider body 330. The support reinforcement structure 370 may be located relatively closer to the front end portion 310 than the rear end portion 320, i.e., the distance between the support reinforcement structure 370 and the rear end portion 320 is greater than the distance between the support reinforcement structure 370 and the front end portion 310, so that the support reinforcement structure 370 can provide additional support to the front end portion 310 in addition to preventing the divider body 330 from bending, to reinforce the strength of the front end portion 310, to prevent the front end portion 310 from being deformed during the operation of the divider 300.

In one embodiment, the support reinforcement structure 370 may include two sets of protrusions 371, as shown in FIG. 2. The two sets of protrusions 371 may be attached to each other (configuration shown in fig. 2) or may be spaced apart from each other (not shown). One set of projections may be at an intermediate position along the length of the divider body 330 and another set of projections may be closer to the front end 310. It will be appreciated by those skilled in the art that the support reinforcement structure 370 may also include one or more than two sets of protrusions, the number of which may be determined according to actual needs.

Each set of protrusions 371 may include one or more protrusions, and the number of protrusions included in each set may be the same or different. For example, one set may include one protrusion and another set may include two protrusions. In the illustrated embodiment, the protrusions have a triangular cross-sectional configuration, which allows for a reduction in weight of the reinforcement structure 370 while ensuring sufficient strength of the divider body 330. It will be appreciated by those skilled in the art that the protrusions may also have any other suitable configuration.

As shown in fig. 2, the pressure intensifying structure 380 is located within the hollow chamber 301 at a location of the divider body 330 proximate the rear end 320. Since the width of the divider body 330 is wider as it gets closer to the rear end 320, the pressure of the crop on the divider body 330 is also gradually increased. Thus, the pressure reinforcement structure 380 serves to resist impact and lateral pressure of crops against the separator body 330, preventing deformation of the separator body 330.

The pressure reinforcing structure 380 may include two bosses 381, and the two bosses 381 may be symmetrically arranged with respect to the length direction of the separator 300. The bosses 381 may be integral with the edges of the cut-out 340. The side of the boss 381 facing away from the rear end 320 may form a rounded corner 382 with the edge of the cut-out 340 to enhance the effect of the boss 381 against impact and lateral pressure from the crop. In other embodiments, the other side of the boss 381 may also form a rounded portion with the edge of the cut-out 340.

The bosses 381 may be disposed such that the support 362 is between the two bosses 381 to further improve the strength against impact force and lateral pressure. In one embodiment, the bosses 381 and the supports 362 may be integrally formed to facilitate manufacturing and to improve strength.

Although exemplary embodiments of the present disclosure have been described, it will be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without substantially departing from the spirit and scope of the present disclosure. Accordingly, all changes and modifications are intended to be included within the scope of the present disclosure as defined in the appended claims. The disclosure is defined by the following claims, with equivalents of the claims to be included therein.
