Abstract
Description
[Technical field]
[0001] The present invention relates to a crop harvester. [Background technology]
[0002] Patent Document 1 discloses a harvester that can neatly stack agricultural products such as green onions in a storage section. Moreover, Patent Document 2 discloses a vegetable harvesting device that stores vegetables, the stems and leaves of which are to be harvested, in a receiving case without damaging them. Also, for example, takana is processed into various pickles, mainly in the Kyushu region. When harvesting takana, it is necessary to air-dry it in the field, so the harvesting work involves cutting the stems of takana cultivated in ridges, turning them over, lining them up in the field, air-drying them, and collecting the takana after air-drying for half a day to a day.

[0004] [Patent Document 2] JP 2010-252677 A Summary of the Invention [Problem to be solved by the invention]
[0005] However, devices for storing harvested crops in containers as in Patent Documents 1 and 2 are not suitable for crops that need to be lined up in a field to dry after harvesting. Also, since harvesting crops such as Takana requires a lot of labor to be done, which can be dried more efficiently by lining them upside down in the field after harvesting, there was a demand for automation. [Means for solving the problem]
[0006] One aspect of the present invention is a crop harvester that cuts crops with a cutting blade, supports the crops on a loading plate, sandwiches the crops between a pair of conveyor belts, and arranges the crops in furrows.The crop harvester comprises a lower resistor provided near the end of the loading plate and applies resistance to transport to the lower part of the crops, and an upper resistor provided near the exit of the conveyor belts and scrapes in the upper part of the crops, and the lower resistor and upper resistor work together to turn the crops upside down and arrange them in the furrows. Effect of the Invention
[0007] According to the present invention, the process of turning harvested crops upside down and arranging them in the field can be automated. [Brief description of the drawings]

[Figure 7] A diagram showing the process by which the harvested Takana CM is turned over and arranged in the furrow R1. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0009] (Embodiment 1) (composition) (Basic configuration) Fig. 1 is a left side view of a takana harvester 1 (crop harvester) according to the first embodiment. Fig. 2 is a plan view of the takana harvester 1. The takana harvester 1 is a device that harvests takana CM while traveling. The upper part of the takana CM is the leaf, and the lower part is the stem.
[0010] The Takana harvester 1 travels with the front wheels 14 and rear wheels 12 in contact with the furrows R1 between the ridges R formed in the field. The pair of left and right rear wheels 12 are positioned so as to straddle one ridge R from side to side. The Takana harvester 1 is a three-wheeled, rear-wheel drive walk-behind type agricultural harvester, and an operator holding a steering handle (not shown) steers the Takana harvester 1 from behind while walking on the furrow R1 where the left rear wheel 12 is located.
[0011] The Takana harvester 1 has a running body 10. The running body 10 is equipped with a base 31, a conveyor belt 35, a loading plate 37, a resistance roller 37b, a raking blade 39, a first chute 38, and a second chute 40, and further, although not shown, an internal combustion engine that drives a pair of left and right rear wheels 12 and the conveyor belt 35 is also installed.
[0012] The running body 10 has a machine frame 11 extending in the front-rear direction. The machine frame 11 is located on the left side of the takana harvester 1. The running body 10 has a first support member 13 and a second support member 15 extending to the left and right, respectively. The first support member 13 is fixed to the rear end of the machine frame 11 and extends to the right from the machine frame 11. The second support member 15 is fixed to a midpoint of the machine frame 11 in the front-rear direction and extends to the right from the machine frame 11.
[0013] A pair of left and right rear wheels 12 (rear parts of the running body 10) are fixed to an axle 12a that passes through the machine frame 11 and the first support member 13 from left to right. The running body 10 has one front wheel 14 (front part of the running body 10). The front wheel 14 is located on the left side of the takana harvester 1.
[0014] The Takana harvester 1 has a base 31 fixed to the traveling body 10. The base 31 is fixed to the second support member 15 and extends upward toward the front from the second support member 15. A rotary cutting blade (cutting blade) 33 is attached to the base 31.
[0015] The rotary cutting blade 33 is a disc-shaped blade that rotates when the driving force of the internal combustion engine is transmitted to it and cuts the stems of the Takana CM. The rotary cutting blade 33 is held in a downward-facing position at the front end of a cutting blade holding member 34 that extends forward from the base 31. The rotary cutting blade 33 is located near the center of the pair of rear wheels 12 in the left-right direction, and is therefore in a position that overlaps with the ridge top portion R2, which is the uppermost portion of the ridge R in a plan view, when the front wheels 14 and the rear wheels 12 are positioned in the ridge furrow.
[0016] (Mechanism for adjusting the height of the rotary blade) It is desirable that the rotary cutting blade 33 cuts the takana CM at a position approximately 2 to 4 cm above the ridge top R2 (approximately at the position of the ridge top R2). In order to adjust the height of the rotary cutting blade 33 to the position of approximately the ridge top R2, the takana harvester 1 is provided with a first adjustment mechanism 50 and a second adjustment mechanism 60 for adjusting the height of the rotary cutting blade 33. By appropriately adjusting the height position of the rotary cutting blade 33, it is possible to prevent the leaves from scattering when the takana CM is cut above the stem, and to prevent the rotary cutting blade 33 from coming into contact with the ridge R.
[0017] (1st adjustment mechanism 50) The front wheel 14 is attached to one end of a front wheel rotating arm 17 via a shaft 14a, and the other end of the front wheel rotating arm 17 is connected to a front wheel support shaft 17a. The front wheel support shaft 17a passes through the vehicle frame 11 and is connected to one end of a connecting link member 51 inside the vehicle frame 11. One end of a hollow connecting arm 53 is connected to the other end of the connecting link member 51 via a connecting shaft 52. A female thread (not shown) is formed on the inner periphery of the other end of the connecting arm 53, and a male thread 55a on the rod 55 side is screwed into the female thread. The rod 55 has a straight portion 55b and a handle portion 55c (first operating portion).
[0018] When the operator turns the handle portion 55c, the amount of tightening of the male screw 55a relative to the female screw of the connecting arm 53 changes, and the connecting arm 53 moves forward and backward. When the connecting arm 53 moves forward and backward, the connecting link member 51 and the front wheel rotating arm 17 rotate around the front wheel support shaft 17a, the front end of the machine body frame 11 moves up and down, and the second support member 15, the base portion 31, the cutting blade holding member 34, and the rotary cutting blade 33 move up and down together with the machine body frame 11, and the height of the rotary cutting blade 33 is adjusted. Hereinafter, the connecting arm 53, the straight portion 55b, the connecting link member 51, and the front wheel rotating arm 17 are collectively referred to as the first connecting mechanism 50a. The first connecting mechanism 50a connects the handle portion 55c and the front wheel 14, and is displaced by operating the handle portion 55c to adjust the height of the rotary cutting blade 33 to the position of approximately the ridge top R2.
[0019] (Second adjustment mechanism 60) FIG. 3 is a left side view of the second adjustment mechanism 60. FIG. The second adjustment mechanism 60 has a rod holding part 62, and the rod holding part 62 holds the straight part 55b of the rod 55 of the first adjustment mechanism 50. The front body S1 and the rear body S2, which extend radially outward from the straight part 55b, are fixed to the straight part 55b, and the straight part 55b between the front body S1 and the rear body S2 is inserted into the rod holding part 62. The rod 55 is rotatable inside the rod holding part 62. The front body S1 and the rear body S2 contact the rod holding part 62 to restrict the relative movement between the rod 55 and the rod holding part 62 in the front-rear direction, and move the rod 55 and the rod holding part 62 together in the front-rear direction. The second adjustment mechanism 60 has a base part 61 mounted on the traveling body 10, a rod holding part 62, a parallel link mechanism 63, and a lever stopper 65.
[0020] The parallel link mechanism 63 is a closed-loop four-bar link mechanism in which a pair of opposing links 63a, 63c and another pair of opposing links 63b, 63d have the same length. The link 63c is fixed to the base 61, and the links 63a to 63d are connected by the joints 63e to 63h. The above-mentioned rod holding part 62 is attached to the upper surface of the link 63a. The link 63d is provided with an operating lever (second operating part) 64 that extends rearward from the joint part with the link 63c. The operating lever 64 is a rod-shaped member that extends rearward. The operating lever 64 rotates integrally with the link 63d around the joint 63g. The operating lever 64 is sufficiently longer than the link 63d, and can easily displace the parallel link mechanism 63. A joint part 64a is provided in the middle of the operating lever 64, and a part rearward of the joint part 64a is formed so as to be swingable left and right around the joint part 64a.
[0021] FIG. 4 is a rear view of the lever stopper 65. FIG. The lever stopper 65 is a plate-shaped member fixed to the base portion 61. A lever movement hole 65a through which the operating lever 64 is inserted is formed in the lever stopper 65. The lever movement hole 65a is a hole that extends vertically. Furthermore, the lever stopper 65 is provided with four notches 65b spaced apart vertically, and each of the notches 65b is connected to a lever movement hole 65a. The operating lever 64 can be inserted into each of the notches 65b, and the notches 65b restrict the rotation of the operating lever 64. In other words, the lever stopper 65 positions the operating lever 64 and the parallel link mechanism 63 at stages according to the number of the formed notches 65b.
[0022] When an operator swings the operation lever 64 up and down, the parallel link mechanism 63 is displaced, and the rod holding part 62 connected to the link 63a moves back and forth. As a result, the rod 55 and the connecting arm 53 move back and forth together with the rod holding part 62, and the rotary cutting blade 33 moves up and down as in the case of the first adjustment mechanism 50. Hereinafter, the parallel link mechanism 63 and the rod holding part 62 are collectively referred to as the second connecting mechanism 60a. The second connecting mechanism 60a connects the operation lever 64 and the first connecting mechanism 50a. In addition, the second connecting mechanism 60a is displaced by operating the operation lever 64, thereby displacing the first connecting mechanism 50a and adjusting the height of the rotary cutting blade 33.
[0023] (Mechanism for transporting and turning over the takana) As shown in FIGS. 1 and 2, a conveyor belt 35 and a placement plate 37 for conveying the grass CM cut by the rotary cutting blade 33 are attached to the base portion 31. The conveyor belts 35 are a pair of circular belts provided on the left and right sides, and have protrusions provided at equal intervals toward the outside of the ring. Each conveyor belt 35 is wound around a plurality of V-pulleys of the belt drive unit 36 fixed to the base unit 31, and is stretched forward and backward in a state of inclination upward toward the rear. The front ends of the pair of conveyor belts 35 are located at positions sandwiching the center of the rotary cutting blade 33 on the left and right, and the rear ends are located to the right of the front ends. Each conveyor belt 35 is driven in a circular manner in the opposite directions by the driving force of the internal combustion engine transmitted to the belt drive unit 36. The stalks of the ...
[0024] The placement plate 37 is a plate-shaped member that is long in the front-rear direction, and supports from below the Takana CM transported by the conveyor belt 35. The placement plate 37 is provided in a position that is approximately parallel to the conveyor belts 35 and occupies the space between the two conveyor belts 35 in a plan view. The placement plate 37 is located below the conveyor belts 35, and is provided at a height such that the conveyor belts 35 can pinch the leaves of the Takana CM with their stems placed on the placement plate 37. Both left and right ends of the placement plate 37 are raised upward. In this embodiment, the placement plate 37 is made of an iron plate that makes it easy for the Takana CM to slide.
[0025] A resistance roller (lower resistance body) 37b is provided at the rear end (near the end of the mounting plate 37) 37a of the mounting plate 37. The rear end 37a is a portion of the mounting plate 37 that is slightly less inclined upward than the other portions of the mounting plate 37 and has an angle slightly closer to horizontal. The resistance roller 37b is a roller that can rotate about an axis in a horizontal direction that is approximately perpendicular to the conveying direction of the conveyor belt 35. The resistance roller 37b is located in an opening formed on the lower surface of the rear end 37a, and approximately half of the upper side of the resistance roller 37b is exposed above the lower surface of the rear end 37a through the opening. The resistance roller 37b comes into contact with the stem of the takana CM conveyed backward on the mounting plate 37 by the conveyor belt 35, and by delaying the conveyance of the stem, the leaves of the takana CM are tilted backward.
[0026] A first chute 38 is connected to a rear end 37a on the outlet side of the placement plate 37. The first chute 38 is a plate-shaped member extending rearward and downward from the rear end of the placement plate 37. The first chute 38 extends parallel to the placement plate 37 in a plan view. The first chute 38 extends to a position where its rear end reaches to the right of the right rear wheel 12. The rear end of the first chute 38 overlaps with the furrow R1 on which the right rear wheel 12 touches the ground in a plan view.
[0027] A pick-up blade (upper resistor) 39 is provided near the exit of the conveyor belt 35. The pick-up blade 39 can rotate about an axis in a horizontal direction substantially perpendicular to the conveying direction of the conveyor belt 35. The pick-up blade 39 has six blades 39a arranged radially around the axis of rotation of the pick-up blade 39. Each blade 39a is a plate made of a flexible material such as rubber or silicon. Each blade 39a is arranged in a direction parallel to the rotation axis of the pick-up blade 39. The pick-up blade 39 comes into contact with the leaves of the takana CM that are released by the conveyor belt 35 and tilted backward, and picks up the leaves of the takana CM downward. Therefore, the takana CM slides down the first chute 38 with the stems located on the upper side.
[0028] FIG. 5 is a perspective view of the second chute 40, showing the second chute 40 as seen from the left front. The second chute 40 is provided at the outlet side of the first chute 38, facing the first chute 38. The second chute 40 overlaps with the furrow R1 on which the right rear wheel 12 touches the ground in a plan view. The second chute 40 drops the takana CM that slides down from the first chute 38 into the furrow R1 with the stems standing upward. The second chute 40 has a main body portion 41 and a buffer portion 43.
[0029] The main body 41 is a member having a generally cylindrical shape penetrating vertically and provided with a notch 41a and an opening 41b. The inner diameter of the main body 41 is large enough for the Takana CM to pass through. The notch 41a is formed in the front part of the side surface of the main body 41, i.e., in the part located on the first chute 38 side, and is a notch that opens upward. The notch 41a is formed over approximately half the circumference of the side surface in the circumferential direction of the main body 41. The notch 41a becomes an entrance when the Takana CM slides down from the first chute 38 into the second chute 40.
[0030] The opening 41b is provided at a position facing the notch 41a on the side surface of the main body 41. The opening 41b is formed to extend downward beyond the notch 41a.
[0031] The buffer section 43 is a plate-like member curved in an arc shape that weakens the momentum of the stacked container CM sliding down into the second chute 40 through contact. The buffer section 43 is provided to close the opening 41b and faces the first chute 38. The buffer section 43 has approximately the same shape as the portion cut out from the main body section 41 when forming the opening 41b. The buffer section 43 is connected to the main body section 41 via a hinge 45 attached to the upper end. The lower part of the buffer section 43 can rotate around the hinge 45 toward the front side, that is, toward the first chute 38.
[0032] The lower part of the buffer part 43 is pushed forward, i.e., toward the direction approaching the first chute 38, by the compression spring 47 extending forward and backward. One end of the compression spring 47 is connected to the rear surface of the lower part of the buffer part 43, and the other end is held by a spring holding part 41c formed on the main body part 41. The spring holding part 41c extends downward from above the opening 41b on the outside of the side surface of the main body part 41, and holds the other end of the compression spring 47 behind the buffer part 43. The falling speed of the high-capacity CM decreases as the high-capacity CM comes into contact with the buffer part 43 pushed forward by the compression spring 47. In this embodiment, the compression spring 47 is a coil spring.
[0033] The main body 41 is formed with a guide portion 41d that is located opposite the buffer portion 43 in a plan view and extends below the buffer portion 43. The guide portion 41d is a side surface of the main body 41 that is not cut out. The guide portion 41d comes into contact with the ta-ka-na CM pushed forward by the buffer portion 43, and guides the ta-ka-na CM vertically downward.
[0034] (Operation during Takana harvest) (Takana harvester running order) FIG. 6 is a schematic diagram showing the running order of the Takana harvester 1 when harvesting the Takana CM. As shown in FIG. 6, the Takana harvester 1 harvests the Takana CM by so-called circular mowing. First, the operator runs the Takana harvester 1 along the outermost ridge R among the multiple ridges R surrounded by the headland HL in the field to harvest the Takana CM. At this time, the traveling direction of the Takana harvester 1 is the direction A in which the ridge R is not located on the right side of the Takana harvester 1. Next, the operator moves the Takana harvester 1 via the headland HL to the opposite and outermost ridge R from the ridge R where the Takana CM was first harvested. After that, the operator runs the Takana harvester 1 along the destination ridge R in the direction B, which is the opposite direction of the direction A. As a result, the two ridge furrows R1 located outside the two outermost ridges R are arranged with the Takana CM facing upward.
[0035] Next, the worker runs the Takana harvester 1 in direction A along the ridge R adjacent to the ridge R from which the Takana CM was first harvested. After that, the worker runs the Takana harvester 1 in direction B along the ridge R adjacent to the ridge R from which the Takana CM was secondly harvested. In this way, the worker runs the Takana harvester 1 on a spiral running path starting from the outermost ridge R until the harvesting of the Takana CM on the innermost ridge R is completed. By harvesting in this order, the Takana CM that has been harvested and arranged in an inverted state in the ridge furrow R1 will not hinder the movement of the Takana harvester 1 and the worker.
[0036] (Operations related to transporting cut takana) 7 is a diagram showing the process in which the katana CM cut by the rotary cutting blade 33 is turned over and arranged in the furrow R1. As shown in FIG. 7(a), the cut katana CM is conveyed upwards with the leaves pinched by the conveyor belt 35 with the stems in contact with the loading plate 37.
[0037] As shown in FIG. 7(b), when the takana CM reaches the rear end 37a of the placement plate 37, the resistance roller 37b comes into contact with the stem of the takana CM from the rear side. This causes the rearward movement speed of the stem of the takana CM to be slower than the rearward movement speed of the leaves of the takana CM sandwiched between the conveyor belts 35. This causes the takana CM to tilt in a direction in which the leaves face rearward. In addition, in this embodiment, the resistance roller 37b rotates due to contact with the takana CM, so that excessive load is unlikely to be applied to the takana CM.
[0038] As shown in Fig. 7(c), the Takana CM sent backward from the rear end of the conveyor belt 35 comes into contact with the sweeping blade 39. Because the leaves of the Takana CM are inclined toward the rear side, the leaves of the Takana CM come into contact with the sweeping blade 39. The sweeping blade 39 sweeps in the leaves of the Takana CM that it comes into contact with downward. In addition, the sweeping blade 39 is rotatable, and each blade 39a is made of rubber or the like, so that the Takana CM is unlikely to be damaged when it is scooped in.
[0039] As shown in FIG. 7(d), the Takana CM that is scooped downward by the scooping blade 39 slides backward down the first chute 38 with its leaves facing backward and downward and its stem facing forward and upward.
[0040] As shown in FIG. 7(e), the takana CM that has slid backward from the rear end of the first chute 38 enters the inside of the second chute 40 through the notch 41a. The leaves of the takana CM come into contact with the buffer section 43 provided in the second chute 40 at a position opposite the first chute 38. As a result, the takana CM moving backward is received by the buffer section 43, the takana CM is made to stand up, and the leaves can be dropped approximately vertically downward in a position where they are located downward. In addition, the buffer section 43 is biased forward by the compression spring 47. Therefore, the buffer section 43 retreats upon contact with the takana CM, and the falling speed of the takana CM is reduced without damaging the takana CM. Even if the takana CM is bounced forward by the buffer section 43, the takana CM falls approximately vertically downward along the guide section 41d.
[0041] The takana CM that falls from the second chute 40 in a substantially vertically downward direction falls with its leaves facing downward into the furrow R1 on which the right rear wheel 12 is in contact with the ground, which is at a position overlapping with the second chute 40 in a plan view. As a result, the takana CM cut by the rotary cutting blade 33 is arranged upside down with respect to the furrow R1. In addition, because the falling speed of the takana CM is reduced by the buffer section 43, the leaves of the takana CM are less likely to be damaged by the impact of the fall.
[0042] (Effects, etc.) As described above, the takana harvester 1 of this embodiment is an agricultural harvester that cuts the takana CM with a rotating cutting blade 33, supports the takana CM on the loading plate 37, clamps it between a pair of conveyor belts 35, and transports the takana CM in the furrows R1.The machine is equipped with a resistance roller 37b provided at the rear end 37a of the loading plate 37 for applying transport resistance to the stems of the takana CM, and a scraping blade 39 provided near the exit of the conveyor belt 35 for scraping in the leaves of the takana CM.The resistance roller 37b and the scraping blade 39 work together to turn the takana CM upside down and arrange it in the furrows R1. This allows the takana CM harvested by the takana harvester 1 to be automatically aligned upside down in relation to the furrow R1.
[0043] Also, as in this embodiment, the outlet of the loading plate 37 may be provided with a first chute 38 which slopes downward, and a second chute 40 which faces the first chute 38 and stands the Takana CM up in an inverted upside down state, and the Takana CM may be arranged in the furrows after passing through the second chute 40. This makes it difficult for the takana CM harvested by the takana harvester 1 to roll when lined up in the furrows. Therefore, the takana CM harvested by the takana harvester 1 can be lined up neatly in the furrows R1 with the furrows turned upside down.
[0044] Further, as in this embodiment, the second chute 40 may be configured to include a buffer portion 43 at a position where the stacked paper CM collides. This allows the falling speed of the takana CM to be reduced. Therefore, the takana CM harvested by the takana harvester 1 can be arranged in an orderly manner in the furrows R1 in an upside-down state without being damaged.
[0045] Also, as in this embodiment, the lower resistor may be configured as the resistance roller 37b, which allows the lower resistor to be configured with a simple structure.
[0046] Also, as in this embodiment, the upper resistor may be configured as a rotary type raking blade 39. This allows the upper resistor to be configured with a simple structure. (Other embodiments)
[0047] In the above embodiment, an example in which the crop harvester of the present invention is applied to the takana harvester 1 has been described, but this is merely one example. For example, the crop harvester of the present invention may be applied to a device for harvesting any leafy vegetable other than takana.
[0048] In the above embodiment, the takana harvester 1 is described as being driven by the driving force of an internal combustion engine, but this is just one example. For example, the takana harvester 1 may be driven by power output from a battery or a generator.
[0049] In the above embodiment, the compression spring 47 is described as a coil spring, but this is only one example. The compression spring 47 may be a spring other than a coil spring, such as a leaf spring. Also, instead of the compression spring 47, an elastic body such as rubber may be connected to the spring holding portion 41c and the buffer portion 43.
[0050] In the above embodiment, the front wheels 14 are described as being provided on the left side of the takana harvester 1, but the front wheels 14 may also be provided on the right side of the takana harvester 1, or on both the left and right sides.
[0051] In the above embodiment, the resistance roller 37b is described as an example of the lower resistor, but this is only an example. The lower resistor may be any structure that can provide a transport resistance to the stem of the takana CM near the end of the mounting plate 37. The resistance roller 37b may be configured to be driven by a driving force from an internal combustion engine or the like.
[0052] In the above embodiment, the raking blade 39 has been described as an example of the upper resistor, but this is merely an example. The upper resistor may be any structure capable of raking downward the leaves of the takana CM sent rearward from the conveyor belt 35. For example, the upper resistor may be a suspended rubber sheet (a so-called sag rubber used for mudguards for trucks, etc.). The raking blade 39 may be configured so that the lower half is driven in a direction toward the rear (counterclockwise on the paper in FIG. 7) by a driving force from an internal combustion engine or the like.
