[0005] Patent Document 1: Japanese Patent Application Publication No. 2020-72749 (JP2020-72749A) Summary of the Invention

[0006] The technical problem that the invention aims to solve

[0007] In order to properly perform its function of separating crops for as many crops as possible, it is preferable that the distance between the left and right dividing devices is as large as possible. On the other hand, if the body supporting the dividing device is increased laterally, the left and right ends of the body may come into contact with the crops planted in the field.

[0008] The purpose of this invention is to provide a harvester that can harvest more crops by suppressing the expansion of the machine body width and increasing the distance between the left and right dividers.

[0009] Technical solutions for solving technical problems

[0010] The harvester of the present invention comprises: a vehicle body; left and right dividers for separating crops to be harvested from crops left in the field; and an arm for supporting the dividers in a state that allows them to swing up and down on the vehicle body. The arm has a first portion as an end on the side of the dividers and a second portion as an end on the side of the vehicle body. The inner end of the first portion in the lateral direction of the vehicle body is located on the outer side of the vehicle body than the inner end of the second portion in the lateral direction of the vehicle body.

[0011] According to this structure, while maintaining the lateral size of the vehicle body, the distance between the left and right dividers is increased, thus allowing more crop to be picked up through the dividers. Additionally, the left and right ends of the vehicle body are less likely to come into contact with the crops planted in the field.

[0012] In this invention, preferably, the vehicle body, the divider, and the arm constitute a linkage mechanism, wherein the arm has an upper arm and a lower arm located below the upper arm.

[0013] According to this structure, the divider swings up and down while its angle is maintained at a certain level by the linkage mechanism. This keeps the divider at an angle that facilitates the intake of crop.

[0014] In this invention, it is preferred that the upper arm and the lower arm extend in a non-parallel manner.

[0015] According to this structure, the distance between the upper arm and the lower arm can be set to a size at which the divider can be stably supported by the upper arm and the lower arm.

[0016] In this invention, preferably, the arm has an inclined portion that extends laterally outward toward the vehicle body in a forward direction.

[0017] According to this structure, compared with the structure in which the arm extends laterally outward to the vehicle body and then bends at a right angle to extend forward, the length of the arm is smaller, thus increasing the distance between the left and right dividers with a simple structure.

[0018] In this invention, it is preferred that the arm is a hollow box-shaped component.

[0019] This structure reduces weight and cost compared to structures where the arm is a solid component.

[0020] In this invention, it is preferred that the arm is capable of swinging about an axis extending laterally along the vehicle body.

[0021] According to this structure, the divider can easily swing up and down by swinging the arm around the axis that extends laterally along the vehicle body.

[0022] In this invention, preferably, a conveying device is also provided, which is located behind the divider to convey the harvested crop. The divider has: a rotating body that can rotate about an upper and lower axis; and a guide member located behind the rotating body that guides the crop toward the conveying device while in contact with the crop. A recess is formed at the lower end of the guide member that is recessed laterally outward toward the vehicle body.

[0023] Because the feeder contacts the protrusion of the field, the divider sometimes goes over the protrusion. In this case, a gap is created between the divider and the field, making it difficult for the divider to pick up the crop. According to this structure, the protrusion of the field enters the recess formed at the lower end of the feeder, thereby preventing a gap from forming between the divider and the field. As a result, the divider can easily pick up the crop.

[0024] In this invention, preferably, the inlet component is a plate-shaped component, and the recess has a first surface that extends downward toward the lateral outer side of the vehicle body.

[0025] According to this structure, the depth of the concave portion increases towards the bottom. Consequently, the convex portion of the field enters the concave portion, making it difficult for the lower end of the guide component to contact the convex portion. Therefore, it is difficult to create a gap between the divider and the field.

[0026] In this invention, preferably, the inlet component is a plate-shaped component, and the recess has a second surface that extends laterally outward toward the vehicle body in a forward direction.

[0027] According to this structure, the depth of the concave portion increases towards the front. Consequently, the convex portion of the field enters the concave portion, making it difficult for the lower end of the guide component to contact the convex portion. Therefore, it is difficult to create a gap between the divider and the field.

[0028] In this invention, preferably, the inlet component is a plate-shaped component, and the recess has: a first surface that extends downward toward the lateral outer side of the vehicle body; a second surface located below the first surface that extends forward toward the lateral outer side of the vehicle body; and a third surface that extends downward from the lower end of the first surface and forward from the front end of the second surface, wherein the angles formed by the first surface and the third surface and the second surface and the third surface are both obtuse angles.

[0029] According to this structure, the depth of the concave portion increases towards the bottom. Furthermore, the depth of the concave portion increases towards the front. As a result, the convex portion of the field enters the concave portion, making it difficult for the lower end of the guide component to contact the convex portion. Therefore, it is difficult to create a gap between the divider and the field.

[0030] Furthermore, even when the crop taken in by the divider enters the recess, the crop is difficult to hook due to the angle between the first and third surfaces or the angle between the second and third surfaces, thus making it easy to guide the crop toward the conveying device.

[0040] Hereinafter, a sugarcane harvester, which is an example of a harvester of the present invention, will be described based on the accompanying drawings. In the following description, the direction of arrow F in the drawings will be designated as "front side", the direction of arrow B as "rear side", the direction of arrow U as "upper side", the direction of arrow D as "lower side", the direction of arrow R as "right side", and the direction of arrow L as "left side".

[0041] [Overall Structure]

[0042] like Figure 1 , Figure 2 , Figure 3 As shown, the sugarcane harvester includes: a vehicle body 1; a running gear 2 supporting the vehicle body 1; a harvesting device 3 for cutting crops; a conveying device 4 for conveying the crops harvested by the harvesting device 3; a screening device 5 that uses screening air to screen the crops into harvested material and impurities; a rear conveying device 6 that conveys the harvested material supplied from the screening device 5 to the rear and discharges it to the outside; a driver's cab 7 for the driver to ride in; and an engine E supported on the vehicle body 1.

[0043] The driving unit 2 has left and right front wheels 21 and left and right rear wheels 22 located behind the front wheels 21. The rear wheels 22 are supported by axle boxes connected to the vehicle body 1. Power from the engine E is transmitted to the left and right rear wheels 22 via a transmission. In other words, the rear wheels 22 are driven by the engine E.

[0044] The front wheels 21 are supported on the vehicle body 1 in a manner that allows them to be raised, lowered, and steered. Power from the engine E is not transmitted to the front wheels 21.

[0045] The conveyor 4 is supported on the vehicle body 1 in a rearward and upward tilted position. Specifically, the lower part of the conveyor 4 is supported on the vehicle body 1. In addition, the rear part of the conveyor 4 is supported on the vehicle body 1 via an axle box or transmission located below the rear part of the conveyor 4.

[0046] The front of the conveying device 4 is connected to the rear of the harvesting device 3. As a result, the crop harvested by the harvesting device 3 is conveyed by the conveying device 4 toward the rear and upper part of the vehicle body 1.

[0047] The screening device 5 is connected to the rear of the conveying device 4. The crop conveyed by the conveying device 4 is chopped at the conveying end of the conveying device 4 and fed to the screening device 5. The crop supplied to the screening device 5 falls downward from the conveying end of the conveying device 4, passing through the interior of the screening device 5. The crop passing through the screening device 5 is screened by using screening air to splash impurities to the outside of the vehicle body 1. The screened harvested material falls to the front of the rear conveyor 6.

[0048] The rear conveyor 6 extends obliquely upward and backward in a tilted position. The rear conveyor 6 conveys the harvested material upward and backward. The conveyed harvested material is discharged from the discharge section located at the rear of the rear conveyor 6 to the outside of the vehicle body 1. Specifically, the harvested material is discharged into the cargo compartment of a transport vehicle traveling parallel to the sugarcane harvester via the rear conveyor 6.

[0049] Harvesting device

[0050] like Figure 1 , Figure 2 , Figure 3 As shown, the harvesting device 3 includes: left and right grass separating bodies 31, which separate the crops to be harvested from the crops left in the field; left and right grain dividers 32, which separate the crops to be harvested from the crops left in the field; arms 33, which support the grain dividers 32 on the vehicle body 1 in a state that allows them to swing up and down; a falling device 38, which falls the crops forward; and a cutter 39, which harvests the roots of the crops that have been fallen using the falling device 38.

[0051] The grass divider 31 is connected to the lower part of the divider 32. When viewed from above, the grass divider 31 has a shape in which the width of the vehicle body narrows as it moves towards the front.

[0052] like Figure 4 As shown, the grass divider 31 has a grass divider cover 31a covering the upper part of the grass divider 31 and a flat grounding member 31b.

[0053] The divider 32 is located in front of the conveyor 4. In other words, the conveyor 4 is located behind the divider 32.

[0054] Arm 33 is a rod-shaped component. Additionally, arm 33 is a hollow, box-shaped component. Arm 33 connects the vehicle body 1 to the divider 32. Arm 33 is capable of swinging relative to the vehicle body 1 about an axis extending laterally along the vehicle body.

[0055] The folding device 38 is a cylindrical component located at multiple positions along the longitudinal direction of the vehicle body. The folding device 38 is capable of rotating about an axis along the transverse direction of the vehicle body. The left and right ends of the folding device 38 are supported on the vehicle body 1 via bearings. The folding device 38 has a hydraulic motor and is driven by the power of the hydraulic motor.

[0056] The cutter 39 is suspended from the vehicle body 1. The cutter 39 has left and right drive shafts extending in the vertical direction. The drive shafts are capable of rotating about an axis in the vertical direction. Multiple cutting edges extend radially from the drive shafts. Driven by the rotation of the drive shafts, the multiple cutting edges rotate about an axis in the vertical direction.

[0057] Power from the hydraulic motor is transmitted to the left and right drive shafts via a gear mechanism. The left and right blades are driven to rotate in opposite directions.

[0058] [Support Frame]

[0059] like Figure 1 , Figure 4 , Figure 5 As shown, the vehicle body 1 has a support frame 11 that supports the driver's unit 7 located above the harvesting device 3.

[0060] The support frame 11 includes upper and lower frames 12 extending horizontally along the vertical direction of the vehicle body, front and rear frames 13 extending horizontally along the front and rear direction of the vehicle body, connecting frame 14 extending laterally along the vehicle body, and left and right sidewalls 15 located laterally inside the vehicle body 1 than the upper and lower frames 12. The sidewalls 15 are plate-shaped components.

[0061] like Figure 4 As shown, the upper and lower frames 12 have a first upper and lower frame 12a and a second upper and lower frame 12b located behind the first upper and lower frame 12a.

[0062] The front and rear frames 13 have a first front and rear frame 13a and a second front and rear frame 13b located below the first front and rear frame 13a.

[0063] The upper part of the first upper and lower frame 12a is connected to the front part of the connecting frame 14. Additionally, the front part of the first front and rear frame 13a is connected to the rear part of the connecting frame 14. That is, the first upper and lower frame 12a is connected to the first front and rear frame 13a via the connecting frame 14. The lower part of the first upper and lower frame 12a is connected to the front part of the second front and rear frame 13b.

[0064] The upper part of the second upper and lower frame 12b is connected to the rear part of the first front and rear frame 13a. The lower part of the second upper and lower frame 12b is connected to the rear part of the second front and rear frame 13b.

[0065] Based on the above structure, the support frame 11 has a rectangular shape when viewed from the side.

[0066] like Figure 5 As shown, the connecting frame 14 is connected to the left and right upper and lower frames 12. In addition, the connecting frame 14 is connected to the left and right first front and rear frames 13a.

[0067] Specifically, the left end of the connecting frame 14 is connected to the upper part of the first upper and lower frame 12a on the left. In addition, the right end of the connecting frame 14 is connected to the upper part of the first upper and lower frame 12a on the right.

[0068] The left end of the connecting frame 14 is connected to the front part of the first front and rear frame 13a on the left. In addition, the right end of the connecting frame 14 is connected to the front part of the first front and rear frame 13a on the right.

[0069] like Figure 4 As shown, the cutter 39 is suspended and supported on the left and right side walls 15 in a forward-leaning position. The left and right side walls 15 are erected opposite each other, separated by the path through which the crop taken in by the divider 32 passes.

[0070] 〔arm〕

[0071] like Figure 4 , Figure 5 As shown, arm 33 is supported on the first upper and lower frames 12a, which can swing up and down. Arm 33 has an upper arm 34 and a lower arm 35 located below the upper arm 34.

[0072] The upper arm 34 has a front portion 34f (corresponding to the first portion) which is the end on the side of the divider 32 and a rear portion 34b (corresponding to the second portion) which is the end on the side of the vehicle body 1. In other words, the front portion 34f is the front end of the upper arm 34. In addition, the rear portion 34b is the rear end of the upper arm 34.

[0073] The upper arm 34 and the lower arm 35 extend in a non-parallel manner. Specifically, when viewed from the side, the angle of the upper arm 34 relative to the horizontal plane is larger than the angle of the lower arm 35 relative to the horizontal plane.

[0074] The rear portion 34b of the upper arm 34 is connected to the upper part of the first upper and lower frame 12a. The upper arm 34 is capable of swinging about the axis P1 that extends laterally along the vehicle body.

[0075] The front portion 34f of the upper arm 34 is connected to the upper part of the left and right divider support frames 32d of the divider 32. The divider support frames 32d extend along the divider 32. The divider support frames 32d are able to swing relative to the upper arm 34 about an axis P3 that extends laterally along the vehicle body.

[0076] The lower arm 35 has a front portion 35f (corresponding to the first portion) which is the end on the side of the divider 32, and a rear portion 35b (corresponding to the second portion) which is the end on the side of the vehicle body 1. In other words, the front portion 35f is the front end of the lower arm 35. In addition, the rear portion 35b is the rear end of the lower arm 35.

[0077] The rear portion 35b of the lower arm 35 is connected to the lower part of the first upper and lower frame 12a. The lower arm 35 can swing up and down about the axis P2 extending laterally along the vehicle body.

[0078] The front portion 35f of the lower arm 35 is connected to the lower part of the divider support frame 32d. The divider support frame 32d is able to swing relative to the lower arm 35 about an axis P4 that extends laterally along the vehicle body.

[0079] The above structure forms a linkage mechanism consisting of the vehicle body 1, the divider 32, and the arm 33. Specifically, the first upper and lower frames 12a, the divider support frame 32d, the upper arm 34, and the lower arm 35 constitute a four-section linkage mechanism.

[0080] The harvesting device 3 has left and right hydraulic cylinders 36. The hydraulic cylinders 36 are connected to the support frame 11. Specifically, the base of the hydraulic cylinder 36 is connected to the upper part of the first upper and lower frame 12a.

[0081] The support frame 11 has a bulge portion 16 that bulges rearward from the first upper and lower frames 12a. The base end of the hydraulic cylinder 36 is connected to the bulge portion 16.

[0082] The harvesting device 3 includes a chain 37 extending across the front end of the hydraulic cylinder 36 and the front side portion 35f of the lower arm 35. The front end of the hydraulic cylinder 36 and the front side portion 35f are connected by the chain 37. As a result, the divider 32 swings up and down via the hydraulic cylinder 36 and the chain 37. That is, the divider 32, connected to the chain 37, swings up and down by the extension and retraction of the hydraulic cylinder 36.

[0083] When the vehicle body 1 is moving, if the divider 32 crosses the protrusion of the field, the chain 37 becomes slack and the lower arm 35 swings upward. As a result, the divider 32 swings upward.

[0084] As the divider 32 passes over the protrusion of the field, the chain 37 changes from a slack state to a taut state due to the weight of the divider 32, etc. Additionally, the lower arm 35 swings downwards. Consequently, the divider 32 swings downwards.

[0085] like Figure 5 As shown, the upper arm 34 has an inclined portion 34i that extends laterally outward toward the vehicle body 1 in a top-down view. Similarly, the lower arm 35 has an inclined portion 35i that extends laterally outward toward the vehicle body 1 in a top-down view.

[0086] When viewed from above, the inclined portions 34i and 35i of the upper arm 34 and the lower arm 35 are located between the front portions 34f and 35f that extend in a straight line along the front-rear direction of the vehicle body and the rear portions 34b and 35b that extend in a straight line along the front-rear direction of the vehicle body.

[0087] The inner ends of the front portions 34f and 35f of the upper arm 34 and the lower arm 35 are located on the outer side of the vehicle body 1, which is closer to the inner ends of the rear portions 34b and 35b on the lateral side of the vehicle body.

[0088] like Figure 5 As shown, the straight-line distance W1 between the rear part 34b of the upper left arm 34 and the rear part 34b of the upper right arm 34 in the transverse direction of the vehicle body is less than the straight-line distance W2 between the front part 34f of the upper left arm 34 and the front part 34f of the upper right arm 34 in the transverse direction of the vehicle body.

[0089] In addition, the straight-line distance W1 between the rear portion 35b of the left lower arm 35 and the rear portion 35b of the right lower arm 35 in the transverse direction of the vehicle body is less than the straight-line distance W2 between the front portion 35f of the left lower arm 35 and the front portion 35f of the right lower arm 35 in the transverse direction of the vehicle body.

[0090] [Grain divider]

[0091] like Figure 4 , Figure 5 As shown, the divider 32 has: an inner screw 32a (equivalent to a rotating body) that can rotate around an upper and lower axis (axis P6); an outer screw 32b (equivalent to a rotating body) located laterally outside the vehicle body 1 than the inner screw 32a, and capable of rotating around an upper and lower axis (axis P5); a screw connecting frame 32c that connects the inner screw 32a and the outer screw 32b; and an infeeding component 8 that guides the crop toward the conveying device 4 while in contact with the crop.

[0092] The internal screw 32a is cylindrical. The internal screw 32a has a helical shape on its outer periphery. The internal screw 32a is driven by a hydraulic motor located at its upper end. When viewed from the side, the internal screw 32a is tilted downwards and rearwards. When viewed from the side, the internal screw 32a rotates about an axis P6 extending obliquely backwards.

[0093] Divider support frame 32d extends along inner screw 32a. Specifically, divider support frame 32d extends from the lower part of inner screw 32a to the upper part of inner screw 32a. Divider support frame 32d is connected to the upper part and the lower end of inner screw 32a.

[0094] The external screw 32b is cylindrical. The external screw 32b has a helical shape on its outer periphery. The external screw 32b is driven by a hydraulic motor located at its upper end. The external screw 32b is tilted downwards and rearwards when viewed from the side. The external screw 32b rotates about an axis P5 that extends obliquely backwards when viewed from the side.

[0095] The screw connecting frame 32c connects the upper part of the inner screw 32a and the upper part of the outer screw 32b. For example... Figure 5 As shown, the screw connecting frame 32c, when viewed from above, extends laterally outward from the rear of the inner screw 32a toward the rear of the outer screw 32b towards the vehicle body 1.

[0096] [Import Component]

[0097] like Figure 6 , Figure 7 , Figure 8 As shown, the import component 8 is a plate-shaped component. In Figure 6 The left-side guide member 8 is located on the left-side divider 32. A lateral outward (inward) direction is formed at the lower end of the guide member 8 towards the vehicle body 1. Figure 6 The recessed portion 81 (left side) extends from the front end of the feed member 8 to the middle of the front and rear portions of the feed member 8. The feed member 8 is fixed to the divider support frame 32d.

[0098] The feeder component 8 has a folded-back portion 82 formed by folding back from the front end of the feeder component 8 to the lateral outer side of the vehicle body 1. The folded-back portion 82 covers the front part of the divider support frame 32d.

[0099] like Figure 6 As shown, the guide member 8 is located further rearward than the lower end of the internal screw 32a. In other words, the guide member 8 is located behind the internal screw 32a.

[0100] like Figure 4 , Figure 5 As shown, the feeder 8 covers the space from the side wall 15 to the divider 32 from the lateral inner side of the vehicle body 1. Therefore, the crop scooped up by the divider 32 will not enter the space from the side wall 15 to the divider 32.

[0101] The guide member 8 extends from the lower part of the divider 32 to the upper part of the divider 32. Specifically, the guide member 8 extends from the lower end of the inner screw 32a to the upper part of the inner screw 32a. However, it is not limited to this; the guide member 8 may also extend from the lower part of the divider 32 to the upper and lower middle parts of the divider 32. The lower end of the guide member 8 is located at the same height as the lower end of the dividing body 31.

[0102] The guide component 8 extends from the front of the side wall 15 to the rear of the divider 32. Specifically, the guide component 8 extends from the front of the side wall 15 to the front of the divider support frame 32d. The lower end of the guide component 8 extends from the rear of the divider body 31 to the front of the side wall 15. However, it is not limited to this; the guide component 8 may not extend from the front of the side wall 15 to the rear of the divider 32 if the space from the side wall 15 to the divider 32 is covered by other components.

[0103] The guide component 8 covers the hydraulic cylinder 36 from the lateral inner side of the vehicle body 1. This prevents the crop from contacting the hydraulic cylinder 36 and thus preventing the arm 33 from swinging.

[0104] [Concave]

[0105] like Figure 6 , Figure 7 , Figure 8 As shown, the recess 81 has: a first surface 81a, which extends downwards at an angle to the outer side of the vehicle body 1; a second surface 81b, which is located below the first surface 81a and extends forwards at an angle to the outer side of the vehicle body 1; and a third surface 81c, which extends downwards from the lower end of the first surface 81a and forwards from the front end of the second surface 81b. In this embodiment, the first surface 81a, the second surface 81b, and the third surface 81c are planar.

[0106] like Figure 7 As shown, when viewed from the front, the angle θ1 formed by the first surface 81a and the third surface 81c is an obtuse angle. Therefore, compared to the case where the angle θ1 is smaller than an obtuse angle, the crop is less likely to get hooked, and thus it is easier to guide the crop towards the conveyor device 4.

[0107] like Figure 8 As shown, when viewed from below, the angle θ2 formed by the second surface 81b and the third surface 81c is an obtuse angle. Therefore, compared to the case where angle θ2 is smaller than an obtuse angle, the crop is less likely to get hooked, and thus it is easier to guide the crop toward the conveyor device 4.

[0108] Figure 5 , Figure 7 , Figure 8 The line L3, indicated by the single-dot dash, is an imaginary line that passes through the inner lateral end of the vehicle body 1 in component 8 and extends along the longitudinal direction. Additionally, in Figure 5 , Figure 7 , Figure 8 Line L4, represented by a single-dot dash, is an imaginary line extending along the inner lateral end of the vehicle body 1 in the inlet component 8, i.e., the third surface 81c. Line L4 is located laterally outside the vehicle body 1 than line L3. The straight-line distance W3 between L3 in the left divider 32 and L3 in the right divider 32 in the lateral direction of the vehicle body is smaller than the straight-line distance W4 between L4 in the left divider 32 and L4 in the right divider 32 in the lateral direction of the vehicle body.

[0109] Line L4 passes through the inner lateral end of the vehicle body 1 of the grass divider 31. That is, the third surface 81c in the recess 81 and the inner lateral end of the vehicle body 1 in the grass divider 31 are at the same position in the lateral direction of the vehicle body. As a result, the third surface 81c does not protrude further into the lateral direction of the vehicle body 1 than the grass divider 31, thus allowing for the wide access of crops to the field.

[0110] [Other Implementation Methods]

[0111] This invention is not limited to the embodiments described above. For example, it may be configured as in other embodiments described below. In other embodiments described below, structures identical to those in the embodiments are labeled with the same numbers and reference numerals as those in the embodiments described above.

[0112] [1] In the above embodiment, arm 33 has an upper arm 34 and a lower arm 35. However, the number of arms 33 is arbitrary. For example, there may be one arm 33 or more arms 33.

[0113] [2] At least one of the upper arm 34 and the lower arm 35 may not have inclined portions 34i and 35i, and may extend forward while bending after extending laterally outward to the vehicle body 1. Alternatively, at least one of the upper arm 34 and the lower arm 35 may also extend forward while bending at a right angle after extending laterally outward to the vehicle body 1.

[0114] [3] In the above embodiment, the inner ends of the front portions 34f and 35f of the upper arm 34 and the lower arm 35 in the transverse direction of the vehicle body are located on the outer side of the vehicle body 1, which is closer to the inner ends of the rear portions 34b and 35b in the transverse direction of the vehicle body.
