DETAILED DESCRIPTION OF THE INVENTION

[0011] An embodiment of the present invention will be described with reference to FIGS.

[0012] 1 and 2, reference numeral 1 denotes a harvester, which is an agricultural machine, and this harvester 1 is a self-propelled harvesting device for harvesting a harvest product W grown in a farm field. The harvest product W is, for example, potatoes (agricultural crops) grown in the soil of the furrows of the farm field.

[0013] The harvester 1 is equipped with a harvester body 2 that travels forward (in the direction of travel) along the ridges of a farm field, digging up and transporting harvested product W from the soil of the ridges.

[0014] The harvester body 2 has a frame 5, an engine 6 which is a drive source installed on the frame 5, a transmission (HST) 4 to which power from the engine 6 is transmitted, left and right crawlers 7 which operate based on the power from the transmission (HST) 4 and travel on the field, and a transport means 8 which operates based on the power from the engine 6 and transports the harvested product W.

[0015] The harvester body 2 also has left and right gauge wheels 11 that move over the field while sandwiching the field ridges, and a digging blade (tip) 12 that digs up the harvested product W from the soil in the field ridges and sends it to the conveying starting end of the conveying means 8.

[0016] Furthermore, the harvester body 2 has a plurality of seats 13 on which operators sit, and an operating means 14 arranged in front of one of the seats 13 (13a), and the operator sitting in that seat 13 (13a) operates the operating lever 15 of the operating means 14 as appropriate.

[0017] Here, the conveying means 8 has an inclined conveying conveyor 16 that receives the harvested product W from the digging blade 12 and conveys it diagonally upward and rearward, and a horizontal sorting conveyor 17 that receives the harvested product W from the conveying conveyor 16 and conveys it rearward. The conveying conveyor 16 is, for example, a rod conveyor, and the sorting conveyor 17 is, for example, a belt conveyor.

[0018] The transport conveyor 16 has a first conveyor section 21 on the front side and a second conveyor section 22 on the rear side, and the first conveyor section 21 is rotatable in the vertical direction relative to the second conveyor section 22 around a left-right axis 23.

[0019] In other words, the first conveyor section 21 enters a working state by rotating downward around the axis 23 based on the contraction of the cylinder (e.g., hydraulic cylinder) 24, and enters a non-working state (upright storage state) by rotating upward around the axis 23 based on the extension of the cylinder 24.

[0020] The harvester 1 also has left and right front loading sections 31 on which the container K is detachably placed, left and right central loading sections 32 on which the container K is detachably placed, and a rear loading section 33 on which the container K is detachably placed.

[0021] The containers (harvest storage containers) K that can be placed on the respective placement sections 31-33 are, for example, storage members with an outer rectangular parallelepiped shape and an open top, and within these storage members, containers K, harvested products W that meet the specifications are manually selected and stored from the harvested products W being transported by the transport means 8 by an operator. The left and right front placement sections 31 are configured symmetrically. Similarly, the left and right center placement sections 32 are also configured symmetrically.

[0022] The rear loading section 33 has a position-changeable rear loading body (liftable container platform) 35 on which the container K is detachably placed. The rear loading body 35 can be raised and lowered relative to the harvester body 2 in response to the operation of a cylinder (e.g., a hydraulic cylinder) 34, and can also be set to an upright storage state.

[0023] The central placement section 32 has a position-changeable central placement body (central container table) 36 on which a container K is detachably placed.

[0024] As shown in Figure 3(a), the central side mounting body 36 is attached to the mounting portion 37 of the machine frame 5 of the harvester main body 2 so that it can rotate vertically around a front-to-rear axis 38, and the axis 38 is inserted into the long hole portion 39 of the central side mounting body 36.

[0025] The downward rotation of the central side mounting body 36 is restricted by the abutment between the abutment portion 41 for restricting the downward rotation of this central side mounting body 36 and the frame portion 40 of the machine frame 5, resulting in a horizontally expanded state (used state), and a container K is placed on this expanded state of the central side mounting body 36.

[0026] 3(b) and 3(c), when an operator manually rotates the central mount body 36 upward about the shaft 38, the central mount body 36 becomes upright and then descends by its own weight by the length of the elongated hole 39. As a result, the upright central mount body 36 is placed in a stored state in which its upward rotation is restricted by the abutment portion 42 for restricting upward rotation coming into contact with the frame portion 40, and its downward rotation is restricted by the abutment portion 41 for restricting downward rotation coming into contact with the frame portion 40.

[0027] The front loading section 31 has a front loading body (front container table) 51 on which a container K is detachably loaded and whose position can be changed.

[0028] As shown in FIGS. 4 to 6, the front mounting body 51 is a mounting body that is rotatable in the horizontal direction and in the vertical direction relative to the machine frame 5 of the harvester body 2.

[0029] That is, the front mounting body 51 is rotatable horizontally about an up-down axis (vertical axis Y) 46 relative to the casing 5 of the harvester body 2, and is rotatable vertically about an up-down axis (horizontal axis X) 47 relative to the casing 5 of the harvester body 2. The horizontal axis X is an imaginary line (rotation center axis) passing through the axis of the horizontal round shaft 47. The vertical axis Y is an imaginary line (rotation center axis) passing through the axis of the vertical round shaft 46, which is the vertical direction.

[0030] The front support body 51 rotates upward around the horizontal axis X (the rotation angle of this upward rotation is approximately 90 degrees) and forward, which is to one side of the horizontal direction, around the vertical axis Y (the rotation angle of this forward rotation is approximately 90 degrees), to an upright storage state (unused state) with its underside facing the harvester main body 2.

[0031] In addition, the front mounting body 51 rotates rearward, which is the other side in the horizontal direction around the vertical axis Y (the rotation angle of this rearward rotation is approximately 90 degrees), and downward around the horizontal axis X (the rotation angle of this downward rotation is approximately 90 degrees), thereby becoming in a horizontally unfolded state (usage state) with its underside facing downward (towards the field scene), and a container K is placed on the front mounting body 51 in this unfolded state.

[0032] In addition, as shown in Figures 4 to 6, the front loading section 31 has a rotating body 52 that is attached to the mounting section 50 of the machine frame 5 of the harvester main body 2 so that it can rotate horizontally around the vertical axis Y, and the front loading section 51 is attached to this rotating body 52 so that it can rotate vertically around the horizontal axis X.

[0033] In other words, the rotating body 52 is mounted on the mounting portion 50 of the machine frame 5 via an axis 46 so as to be rotatable horizontally, and the front mounting body 51 is mounted on the rotating body 52 via an axis 47 so as to be rotatable vertically.

[0034] Therefore, the operator rotates the front support body 51 upward relative to the rotating body 52 around the horizontal axis X, and then rotates the rotating body 52 forward together with the front support body 51 around the vertical axis Y relative to the machine frame 5, so that the front support body 51 enters an upright storage state with its underside facing inward toward the harvester main body 2.

[0035] In addition, the operator rotates the rotating body 52 together with the front mounting body 51 rearward relative to the machine frame 5 around the vertical axis Y, and then rotates the front mounting body 51 downward relative to the rotating body 52 around the horizontal axis X, causing the front mounting body 51 to assume a horizontally deployed state with its underside facing downward.

[0036] 1 and 2 is a horizontally deployed state (used state), and this deployed state is a state in which the front mount body 51 is located at an deployed position to the side of the first conveyor section 21 in the working state. Also, for example, the state of the front mount body 51 shown in FIG. 11(a) is an upright folded state (highest raised state), and this folded state is a state in which the front mount body 51 is located at a folded position to the side of the first conveyor section 21 in the non-working state. Furthermore, for example, the state of the front mount body 51 shown in FIG. 11(b) is an upright stored state (unused state), and this stored state is a state in which the front mount body 51 is located at a stored position to the side of the first conveyor section 21 in the non-working state.

[0037] Furthermore, the front mounting portion 31 has a fixing means 53 for releasably fixing (locking) the front mounting body 51 in a folded state, which is positioned at the folding position by rotating upward around the horizontal axis X, in a predetermined position, i.e., for example, the folding position.

[0038] The fixing means 53, which will be described in detail later, can automatically fix the front mounting body 51 to the folded position simply by manually rotating the front mounting body 51 upward from the unfolded position to the folded position (changing the position from the unfolded position to the folded position). In other words, the fixing means 53 automatically locks the front mounting body 51 to the folded position simply by rotating the front mounting body 51 upward.

[0039] 4, the mounting portion 50 of the machine frame 5 has a bearing hole 55 into which the shaft 46 is inserted and fixed, and also has a first fixing hole 56, a second fixing hole 57, and a third fixing hole 58. The mounting portion 50 is reinforced with a reinforcing plate 59.

[0040] 4 to 6, the rotating body 52 has a longitudinal portion 61 in which a shaft insertion hole 60 is formed, and the shaft 46 is inserted through the shaft insertion hole 60 of the longitudinal portion 61. Plate-like portions 62 are provided at both longitudinal ends of the longitudinal portion 61, and each plate-like portion 62 has a shaft insertion hole 63 formed therein, through which the shaft 47 is inserted. An engagement pin 92, which will be described later, is fixed to one of the plate-like portions 62.

[0041] A U-shaped frame 65 is fixed to the longitudinal middle of the elongated portion 61, and a pin member 66 is attached to the U-shaped frame 65 so as to be movable up and down, and the pin member 66 is biased downward by a compression spring 67, which is a biasing member. An R-shaped pin 68 is attached to the insertion hole of the pin member 66 to prevent it from coming out.

[0042] When the pin member 66 is inserted into the first fixing hole 56, the front mount body 51 in the unfolded state is fixed together with the rotating body 52 at the unfolded position so as to assume the state shown by the two-dot chain line in Fig. 2 (for example, a pair of left and right mount bodies forming a roughly V-shape). When the pin member 66 is inserted into the second fixing hole 57, the front mount body 51 in the unfolded state is fixed together with the rotating body 52 at the unfolded position so as to assume the state shown by the solid line in Fig. 2 (a state in which the longitudinal direction coincides with the front-rear direction). When the pin member 66 is inserted into the third fixing hole 58, the front mount body 51 in the stored state is fixed together with the rotating body 52 at the stored position (see Fig. 11(b)).

[0043] The front loading body 51 has a loading main body portion 71 which is approximately rectangular in plan view and on which the container K is removably placed, and a rotating body mounting portion 72 which is provided at the rear end side of the loading main body portion 71 and is attached to the rotating body 52 via an axis 47 so that it can rotate up and down.

[0044] The loading main body 71 has, for example, a roughly rectangular ring-shaped frame member 73, two rod-shaped container loading members 74, three reinforcing members 75 (75a, 75b, 75b) installed between the two container loading members 74, and two rod-shaped connecting members 76 whose one ends are connected and fixed to the reinforcing member 75 (75a).

[0045] The rotating body mounting portion 72 has a longitudinal portion 81 made of, for example, a rectangular cylindrical pipe member, and the other end of the connecting member 76 is connected and fixed to this longitudinal portion 81. Plate-shaped portions 82 are provided at both longitudinal ends of the longitudinal portion 81, and each plate-shaped portion 82 is formed with a shaft insertion hole 83 through which the shaft 47 is inserted. Cotter pins 85 for preventing the shaft 47 from coming out are inserted into insertion holes 84 at both ends of the shaft 47.

[0046] The fixing means 53 has an engaging plate 91 and an engaging pin 92 which automatically engage with each other when the front mounting body 51 is positioned at the folded position (predetermined position) simply by an operator manually rotating the front mounting body 51 upward from the unfolded position to the folded position around the horizontal axis X.

[0047] The plate-shaped engagement plate (lock plate) 91 is the one-side engagement body, and the protruding engagement pin (lock pin) 92 is the other-side engagement body. This engagement pin 92 is fixed to one of the plate-shaped portions 62 of the rotating body 52.

[0048] The engagement plate 91 is made of a plate-like member bent at, for example, two points, and has a rectangular plate-shaped engagement plate portion 93, a knob portion 95 which is one side plate portion connected to the front end portion, which is one longitudinal end of the engagement plate portion 93, via a bent portion 94, and a guide portion 97 which is the other side plate portion connected to the rear end portion, which is the other longitudinal end of the engagement plate portion 93, via a bent portion 96.

[0049] The engagement plate portion 93 is formed with an elongated engagement hole portion 98 that releasably engages with the engagement pin 92, and also with a similarly elongated shaft insertion hole 99.

[0050] The knob 95 is a plate-like portion that an operator pinches with his or her fingers when releasing the engagement between the engagement pin 92 and the engagement hole 98. The guide 97 is a plate-like portion that guides the engagement pin 92 toward the engagement hole 98 and is pressed by the engagement pin 92 during this guidance. Note that both the knob 95 and the guide 97 are inclined at the same inclination angle (e.g., 30 degrees) relative to the engagement plate 93.

[0051] The fixing means 53 has a support shaft (support shaft portion) 101, which is a round shaft-shaped support body that movably (tiltably) supports the engagement plate 91, and the support shaft 101 is welded and fixed to one of the plate-shaped portions 82. The stepped support shaft 101 has, for example, a large-diameter portion 101a welded and fixed to one of the plate-shaped portions 82, and a small-diameter portion 101b that is smaller in diameter than the large-diameter portion 101a, and the small-diameter portion 101b is inserted into the elongated shaft insertion hole 99.

[0052] A compression spring 102, which is a biasing body that biases the engagement plate 91 toward the large diameter portion 101a, is disposed on the outer circumferential side of the small diameter portion 101b of the support shaft 101. The compression spring 102 is positioned in a compressed state between the engagement plate 91 and a washer 103. A split pin 105 for preventing removal is inserted into an insertion hole 104 at the tip of the small diameter portion 101b of the support shaft 101.

[0053] The engaging plate portion 93 is restricted from rotating relative to the one plate-shaped portion 82 by abutment with an abutment plate 106, which is provided so as to protrude from the one plate-shaped portion 82.

[0054] 7 to 10, a case where an operator rotates the front carrier 51 upward from the unfolded position (lowest position) to the folded position (highest position) to change from the unfolded state to the folded state (operation of rotating upward by an operator) will be described. Note that while the front carrier (left front container base) 51 of the left front carrier section 31 will be described, the same applies to the right front carrier section 31 (the same applies to other descriptions).

[0055] First, as shown in Fig. 7, the front-side mounting body 51 is positioned at the deployed position and in an deployed state. At this time, downward rotation of the front-side mounting body 51 in the deployed state is restricted by the contact between the lower surface of the elongated portion 81 and the frame portion 40 of the machine casing 5, and as a result, the front-side mounting body 51 is in an approximately horizontal deployed state.

[0056] Then, when an operator, for example, grasps the frame member 73 with his / her hand and lifts the front mounting body 51 to rotate the front mounting body 51 upward around the horizontal axis X relative to the rotating body 52, the engagement plate 91 is pushed by the engagement pin 92 and moves against the biasing force of the compression spring 102, as shown in Figures 8 and 9.

[0057] In other words, the engagement plate 91, which rotates upward integrally with the front mounting body 51, is guided by the guide portion 97 and pressed by the tip of the engagement pin 92, which slides along the guide portion 97, causing it to rotate (tilt) around the shoulder portion 100 of the large diameter portion 101a of the support shaft 101 as a fulcrum against the biasing force of the compression spring 102.

[0058] Next, when the operator further rotates the front support body 51 upward and the front support body 51 is positioned in the folded position, as shown in FIG. 10, the engaging plate 91 moves back to its original position (standby position) due to the biasing force of the compression spring 102, and the engaging pin 92 enters the engaging hole portion 98 of the engaging plate 91, and as a result, the engaging pin 92 and the engaging hole portion 98 engage with each other.

[0059] In this way, the worker does not need to perform any other operation (inserting or removing fixing devices such as pins) other than the operation of lifting the front mounting body 51, but simply manually rotates the front mounting body 51 upward from the unfolded position to the folded position (only lifting the front mounting body), and the engagement hole portion 98 of the engagement plate 91 and the engagement pin 92 engage with each other, releasably fixing the front mounting body 51 to the predetermined folded position, and this fixation maintains (fixes) the folded state of the front mounting body 51.

[0060] To release the engagement between the engagement hole portion 98 of the engagement plate 91 and the engagement pin 92 (positioning and fixing to the folded position), the operator simply pinches the knob portion 95 of the engagement plate 91 with his or her fingers and rotates (tilts) the engagement plate 91 around the shoulder portion 100 of the large diameter portion 101a of the support shaft 101 as a fulcrum against the biasing force of the compression spring 102, as shown by the dotted line in Figure 10(b), and this rotation causes the engagement pin 92 to come out of the engagement hole portion 98.

[0061] Next, with reference to FIGS. 11 to 14, a case where an operator horizontally rotates the front mounting body 51 from the folded position to the stored position to change from the folded state to the stored state (horizontal rotation operation by an operator) will be described.

[0062] 11(a), the front mounting body 51 is in the folded position and is folded upright. At this time, the horizontal rotation of the rotating body 52 is restricted by the engagement between the pin member 66 and the second fixing hole 57, and therefore the horizontal rotation of the front mounting body 51 relative to the machine casing 5 about the vertical axis Y is also restricted.

[0063] Then, after the worker releases the engagement between the pin member 66 and the second fixing hole 57, for example, by gripping the frame member 73 with his / her hand, the front mounting body 51 together with the rotating body 52 is rotated horizontally forward around the vertical axis Y, and as shown in Figure 11(b), the front mounting body 51 is positioned at the storage position and assumes an upright storage state.

[0064] At this time, the horizontal rotation of the rotating body 52 is restricted by the engagement of the pin member 66 with the third fixing hole 58, and thereby the horizontal rotation of the front mounting body 51 is also restricted, so that the front mounting body 51 is maintained (fixed) in the upright stored state. Note that the entire front mounting body 51 in this upright stored state is located inside the outer end of the harvester body 2.

[0065] Here, as shown in FIGS. 12 to 14, the front mounting body 51 in the upright stored state is in a state in which the underside thereof faces inward, that is, toward the harvester main body 2.

[0066] That is, the lower surface of the front mounting body 51 in the stored state and the side surface of the first conveyor section 21 of the harvester body 2 in the non-working state (stored state) are spaced apart and face each other at a predetermined distance.

[0067] At this time, the center of gravity G of the front mounting body 51 in the stored state is located slightly outside (outside) the horizontal axis X, which is the rotation center of the front mounting body 51, as seen from the front (see FIG. 14). Note that the center of gravity G may be located directly above the horizontal axis X as seen from the front, or may be located slightly inside (inside) the horizontal axis X as seen from the front.

[0068] For example, if the fixation by the fixing means 53 (engagement between the engagement pin 92 and the engagement hole portion 98) is released due to some malfunction, and the front side mounting body 51 rotates downward around the horizontal axis X toward the outside, opposite the harvester main body 2, based on its own weight, the downward rotation is regulated by the abutment receiving portion 110, which is the rotation regulating portion.

[0069] As shown in Figure 15, this abutment receiving portion 110 is configured, for example, as the portion of the frame portion 40 of the machine frame 5 of the harvester main body 2 that abuts against the round pipe-shaped frame member 73 of the front mounting body 51.

[0070] As shown in Figure 15(a), before the fixation (lock) by the fixing means 53 is released, a gap 109 exists between the lower end of the frame member 73 of the front mounting body 51 and the abutment receiving portion 110 on the upper surface of the frame portion 40.

[0071] However, when the front mounting body 51 rotates downward and outward around the horizontal axis X due to the release of the lock, the lower end of the frame member 73 abuts against the abutment receiving portion 110, as shown in Figure 15(b), and this abutment restricts the downward rotation of the front mounting body 51 outward.

[0072] As a result, even if the lock is released when the front side mounting body 51 is in a stored state (for example, when transporting by truck), the front side mounting body 51 only rotates slightly downward and outward by the amount of the gap 109, and does not fall outward.

[0073] Furthermore, even if the front carrier 51 rotates downward inward rather than outward, the upper end of the container carrier member 74 abuts against the side surface 21a of the non-operating first conveyor section 21, as shown by the two-dot chain line in Fig. 14, and this abutment restricts the downward inward rotation of the front carrier 51. Therefore, in this case as well, the front carrier 51 will not fall inward.

[0074] Furthermore, according to the harvester 1 described above, the fixing means 53 of the front loading section 31 has an engaging plate 91 and an engaging pin 92 that engage with each other when the front loading body 51 is positioned (reaches) the folded position simply by rotating (changing position) the front loading body 51 upward from the unfolded position to the folded position, so the operator can fix the front loading body 51 in the folded position simply by rotating it upward. Therefore, there is no need to insert or remove pin members, as was previously necessary, which reduces the burden on the operator and, moreover, there is no risk of losing parts because there are no parts that need to be removed or attached.

[0075] Furthermore, the fixing means 53 has a support shaft 101 that movably supports the engagement plate 91, and a compression spring 102 that biases the engagement plate 91. When the front mounting body 51 rotates upward, the engagement plate 91 is pushed by the engagement pin 92 and moves against the biasing force of the compression spring 102. When the front mounting body 51 is then positioned in the folded position, the engagement plate 91 moves to its original position due to the biasing force of the compression spring 102, and the engagement hole portion 98 of the engagement plate 91 and the engagement pin 92 engage with each other. Therefore, the front mounting body 51 can be properly fixed in the folded position by the fixing means 53, which has a simple configuration.

[0076] Furthermore, the engagement plate 91 of the fixing means 53 has a gripping portion 95, separate from the guide portion 97, which the worker pinches with his or her fingers when disengaging the engagement hole portion 98 from the engagement pin 92. This allows the worker to easily disengage the engagement between the engagement hole portion 98 and the engagement pin 92 (fixation by the fixing means), further reducing the burden on the worker.

[0077] In the above embodiment, the fixing means for fixing the mounting body in a predetermined position is described as having a configuration in which one side engaging body (engagement plate, etc.) is provided on the mounting body side and the other side engaging body (engagement pin, etc.) is provided on the rotating body side, but this is not limited to this, and it may also be a configuration in which, for example, one side engaging body (engagement plate, etc.) is provided on the rotating body side (fixed side) and the other side engaging body (engagement pin, etc.) is provided on the mounting body side (position change side).

[0078] Furthermore, the predetermined position at which the mounting body is fixed (positioned and fixed) by the fixing means is not limited to the folded position, which is the highest position, but may be any position such as the unfolded position or the stored position.

[0079] Furthermore, the placement section on which the storage member is placed is not limited to the front placement section provided on the front side of the harvester body, but may be, for example, a central placement section or a rear placement section, etc., and is optional.

[0080] Furthermore, the crops harvested by the harvester are not limited to potatoes, but may also be sweet potatoes, onions, carrots, etc. [Explanation of symbols]
