[0010] One embodiment of the present invention will be described with reference to FIGS.
[0011] In Figures 1 and 2, 1 is a ridge coating machine. This ridge coating machine 1 is an agricultural machine that is connected to the rear of a tractor (not shown), which is a vehicle that can travel in a field, and performs ridge coating work while moving in the direction of travel (forward) as the tractor travels.
[0012] The ridge painting machine 1 comprises a body 2 which is detachably connected to a three-point link hitch section (work machine lifting support section) at the rear of the tractor, a rotary-type embankment body (cultivation body) 3 which is rotatably mounted on the body 2 and rotates in a predetermined rotational direction to till the soil on the rice field surface and the ridge (original ridge) and pile it up onto the ridge, a ridge forming body 4 which is rotatably mounted on the body 2 and rotates in a predetermined rotational direction to compact the soil made by the embankment body 3 behind the embankment body 3 to form a new ridge (new ridge), and an upper surface scraping body 5 which is rotatably mounted on the body 2 and rotates in a predetermined rotational direction to scrape the upper surface of the ridge (upper surface of the original ridge) in front of the embankment body 3.
[0013] The embankment body 3 performs embankment work while rotating in a predetermined rotation direction (up-cut direction, which is the opposite direction to the rotation direction of the ridge forming body) around a horizontal rotation center axis X1 in the left-right direction. The ridge forming body 4 performs ridge formation work while rotating in a predetermined rotation direction around a horizontal rotation center axis X2 in the left-right direction.
[0014] The ridge coating machine 1 also includes an embankment cover 6 which is a cover body that covers the embankment body 3, a ridge forming body cover 7 which covers part of the ridge forming body 4, and an upper surface scraping body cover 8 which covers the upper surface scraping body 5.
[0015] The machine body 2 has a fixed machine frame 11 that is detachably connected to a three-point link hitch at the rear of the tractor. The fixed machine frame 11 has a shaft holding portion 12 that rotatably holds an input shaft 13, and the input shaft 13 is connected to the PTO shaft of the tractor via a joint.
[0016] One end of a pair of left and right rotating arms 15 is rotatably attached to the fixed machine frame 11, and a movable machine frame 16, which also serves as a transmission case, is rotatably attached to the other end of each of the rotating arms 15. The movable machine frame 16 moves in response to the rotation of both rotating arms 15 based on the extension and contraction of a cylinder 17 such as an electric hydraulic cylinder.
[0017] The movable machine frame 16 also has a shaft holding section 18, which rotatably holds an intermediate input shaft (not shown) connected to the input shaft 13 via a joint 19. The embankment body 3, ridge forming body 4 and upper surface scraping body 5 are driven to rotate based on the power input to the intermediate input shaft. The embankment body 3, ridge forming body 4 and upper surface scraping body 5 are each rotatably mounted at predetermined locations on the movable machine frame 16.
[0018] The embankment body 3 has a rotating shaft 21 which is a left-right drive shaft that rotates around a central rotation axis X1, and a plurality of embankment tines (cultivation tines) 22 attached to the rotating shaft 21 and used for embankment work (cultivation work).
[0019] The ridge forming body 4 has a rotary shaft 23 which is a left-right drive shaft that rotates about a central rotation axis X2, and a ridge forming member 24 which is attached to the rotary shaft 23 and performs ridge forming work.
[0020] The ridge forming member 24 has a truncated cone-shaped (including substantially truncated cone-shaped) ridge side forming part (side disk) 26 that compacts the embankment made by the embankment body 3 while rotating in a predetermined direction about the rotation center axis X2 together with the rotating shaft 23 to form a ridge side (ridge slope) with a downward slope toward the rice field surface side, and a cylindrical (including substantially cylindrical) ridge top surface forming part (upper surface roller) 27 that is connected to the reduced diameter side end (right end) of the ridge side forming part 26 and compacts the embankment made by the embankment body 3 while rotating in a predetermined direction about the rotation center axis X2 together with the rotating shaft 23 to form a horizontal ridge top surface. The ridge side forming part 26 has a plurality of ridge side forming plates 28 arranged in the rotation direction, for example, and each of these ridge side forming plates 28 is detachably attached to a base plate 29.
[0021] The upper surface scraping body 5 has a rotating shaft 31 which is a drive shaft in the front-rear direction, and a plurality of scraping claws 32 which are attached to the rotating shaft 31 and perform the upper surface scraping work.
[0022] Here, as shown in Figures 3 to 5, the embankment cover 6, which covers at least the upper side of the embankment body 3, guides the soil (cultivated soil) released by the embankment tines 22 of the embankment body 3 and discharges and supplies it toward the ridge forming body 4 from the supply port (discharge port) 40, which is the opening at the rear end, and prevents the soil (cultivated soil) released by the embankment tines 22 of the embankment body 3 from scattering around.
[0023] The embankment cover 6 has a left cover part 41 which is one side cover part, a right cover part 43 which is the other side cover part, and a central cover part 42 located between the left cover part 41 and the right cover part 43. The central cover part 42 is a ridge side soil supply part which guides the soil released by the embankment tines 22 of the embankment 3 and supplies the tilled soil from the supply port 40 toward the lower side of the ridge side forming part 26. The right cover part 43 is a ridge top soil supply part which guides the soil released by the embankment tines 22 of the embankment 3 and supplies the tilled soil from the supply port 40 toward the lower side of the ridge top forming part 27.
[0024] In other words, the embankment cover 6 has a left side cover part 41, a central cover part 42 which is a soil supply part for the side of the ridge connected to the right end part of the left side cover part 41, and a right side cover part 43 which is a soil supply part for the top surface of the ridge connected to the right end part of the central cover part 42.
[0025] The left cover part 41 has a curved plate 51 in the shape of a substantially circular arc that follows the trajectory of the tip of the embankment claw 22 of the embankment body 3, and a flat left side plate 52 protrudes downward from the left end of this curved plate 51. A notch 53 is formed in the lower part of the left side plate 52, and the rotation shaft 21 of the embankment body 3 is inserted into this notch 53.
[0026] The central cover section (the first soil supply section, the soil supply section for the ridge side) 42 mainly supplies soil to at least the expanded end side (inner end side) of the ridge side forming section 26 of the ridge forming body 4, i.e., for example, toward the front of the lower side of approximately the left half of the ridge side forming section 26.
[0027] The central cover portion 42 has an upper plate 61 at the rear, which has a soil-guiding plate portion 60 at its rear end that is inclined, high at the front and low at the rear when viewed from the side, and this upper plate 61 is formed into a curved plate that convex upwards.
[0028] A flat intermediate side plate 62 protrudes downward from the left end of the upper plate 61 , and this intermediate side plate 62 is connected and fixed to the right end of the curved plate 51 of the left cover portion 41 .
[0029] Furthermore, an inner cover body 63 formed in a flat plate shape is attached to the intermediate side plate 62 via a rubber plate 64 , and the angle of this inner cover body 63 with respect to the front-rear direction can be adjusted by an adjustment plate 65 .
[0030] A plurality of pin insertion holes 66 are formed in the front end of the adjustment plate 65, and a fixed pin 68 erected on a protruding plate portion 67 of the curved plate 51 is inserted into any one of the plurality of pin insertion holes 66 selected from the plurality of pin insertion holes 66, and a stop pin 69 is attached to the fixed pin 68. Similarly, a plurality of pin insertion holes 71 are formed in the rear end of the adjustment plate 65, and a fixed pin 73 erected on a protruding plate portion 72 of the inner cover body 63 is inserted into any one of the plurality of pin insertion holes 71 selected from the plurality of pin insertion holes 71, and a stop pin 74 is attached to the fixed pin 73.
[0031] The right side cover part (the second soil supply part, the ridge top surface soil supply part) 43 mainly supplies soil to at least the inner end part of the ridge top surface forming part 27 of the ridge forming body 4, i.e., for example, toward the front of the lower side of approximately the left half of the ridge top surface forming part 27.
[0032] And, like the central cover part 42, the right side cover part 43 has an upper plate 81 at its rear part, which has a soil guiding plate part 80 at its rear end part that is inclined from front to rear in a side view, and this upper plate 81 is formed in a curved plate shape that is convex upward, and this upper plate 81 is located at a higher position than the upper plate 61 of the central cover part 42. In other words, the right side opening 43a which is an opening of the right side cover part 43 is provided so as to be located at a higher position than the central opening 42a which is an opening of the central cover part 42 (see FIG. 4).
[0033] In the example shown in Fig. 6, the inclined plate portion (inclined plate) 60 of the upper plate 61 of the central cover portion 42 and the inclined plate portion (inclined plate) 80 of the upper plate 81 of the right cover portion 43 are positioned parallel to each other, but they do not necessarily have to be parallel. In the example shown in Fig. 6, the distance between the plate portion 60 on the central cover portion 42 side and the plate portion 80 on the right cover portion 43 side located above the plate portion 60 is approximately constant in side view, but the distance between them may be changed depending on, for example, the field conditions.
[0034] A flat intermediate side plate 82 protrudes downward from the left end of the upper plate 81, and this intermediate side plate 82 is connected and fixed to the right end of the upper plate 61 of the central cover part 42. On the other hand, a curved right side plate 83 protrudes downward from the right end of the upper plate 81, and a side cover body 85 is provided on this right side plate 83 so as to be vertically movable.
[0035] The right side plate 83 is bent so that the supply port 40 opening toward the rear side widens, but a rotating plate that can be rotated and adjusted may be provided on the rear end side so that the opening amount of the supply port 40 can be changed, for example. The embankment cover 6 is provided with a rubber cover 86, which is an elastic cover that can be elastically deformed, positioned from the front end side to the right end side of the embankment cover 6.
[0036] Next, the operation of the above-mentioned ridge coating machine 1 will be described with reference to Figures 5 to 9. The arrows in Figures 5 to 9 indicate the direction in which soil is released by the embankment claws 22 of the embankment body 3 during rotation in the up-cut direction.
[0037] When the ridge coating machine 1 is connected to the rear of a tractor and moved in the forward direction along the ridge by the tractor, the upper surface of the ridge is scraped by the upper surface scraper 5 to remove weeds and the like, and behind this upper surface scraper 5, the soil on the rice field surface and on the ridge is cut and tilled by the soil banking body 3, and the tilled soil is supplied toward the ridge forming body 4 and piled up on the ridge.
[0038] Then, the bank made of tilled soil piled up on the ridge (on the original ridge) is compacted by the ridge forming body 4 to form a new ridge. That is, the bank is compacted by the ridge side forming portion 26 of the ridge forming body 4 to form the inclined ridge side of the new ridge, and the bank is compacted by the ridge top surface forming portion 27 of the ridge forming body 4 to form the horizontal ridge top surface of the new ridge.
[0039] During such ridge-plastering work, a portion of the soil that is plowed and released by the embankment tines 22 of the embankment body 3 rotating in the up-cut direction is guided by the embankment body cover 6 and supplied to the ridge forming body 4 through its supply port 40, as shown by the arrows in Figures 5 to 9.
[0040] More specifically, the left cover part 41 of the embankment cover 6 guides the soil from the embankment claw 22 side of the embankment body 3 so as to rotate around, and supplies some of the soil to the right side. Also, the central cover part 42 of the embankment cover 6 guides the soil from the embankment claw 22 side of the embankment body 3 and forcibly supplies it toward the underside of the enlarged diameter end side of the ridge side forming part 26 of the ridge forming body 4, and the right cover part 43 of the embankment cover 6 guides the soil from the embankment claw 22 side of the embankment body 3 and forcibly supplies it toward the underside of the reduced diameter end side of the ridge side forming part 26 of the ridge forming body 4 and toward the ridge top surface forming part 27 side.
[0041] As a result, the desired amount of soil is supplied in a balanced manner to the front side of each of the ridge side forming portion 26 and the ridge top surface forming portion 27, and the supplied piled-up soil (cultivated soil) is compacted by both portions to form a strong new ridge.
[0042] Furthermore, with this type of ridge painting machine 1, the embankment cover 6 covering the embankment 3 has a central cover portion 42 which is a ridge side soil supply portion that guides soil from the embankment 3 side within the embankment cover 6 and discharges and supplies it toward the ridge side forming portion 26 side of the ridge forming body 4, and a right cover portion 43 which is a ridge top surface soil supply portion that guides soil from the embankment 3 side within the embankment cover 6 and discharges and supplies it toward the ridge top surface forming portion 27 side of the ridge forming body 4, so that it is possible to distribute and supply the desired amount of soil required to form a new ridge in a balanced manner to each of the ridge side forming portion 26 and the ridge top surface forming portion 27, respectively, and therefore appropriate ridge painting work can be performed.
[0043] Moreover, it is possible to form stable and strong new ridges even in soil conditions and moisture conditions that make it difficult to crush soil, and the rotation speed of the rotating shaft 21 of the inverted type embankment body 3 can be increased to improve soil crushing properties and soil supply capacity, making it possible to appropriately respond to various field conditions and increasing versatility.
[0044] In addition, each of the central cover portion 42 and the right side cover portion 43 of the embankment cover 6 has an upper plate 61, 81 at its rear which has an inclined (including curved) plate portion 60, 80 at its rear end which is higher at the front and lower at the rear when viewed from the side, and the upper plate 80 of the right side cover portion 43 is positioned higher than the upper plate 60 of the central cover portion 42, so that the desired amount of soil can be appropriately supplied to each of the ridge side forming portion 26 and the ridge top surface forming portion 27, thereby enabling even more appropriate ridge painting work.
[0045] In addition, the ridge side soil supply section, which supplies soil from the embankment side toward the ridge side forming section, is not limited to supplying soil toward the lower side in approximately the left half of the ridge side forming section, but may, for example, supply soil toward the entire lower side of the ridge side forming section.
[0046] Furthermore, the ridge top surface soil supply section that supplies soil from the embankment side toward the ridge top surface forming section is not limited to one that supplies soil toward the lower side in approximately the left half of the ridge top surface forming section, and may be, for example, one that supplies soil toward the lower side of the entire ridge top surface forming section. As shown in Figure 5, the ridge top surface soil supply section (right cover section 43) shown in Figure 5 supplies a portion of the soil from the embankment side toward the ridge side surface forming section, but may be configured to supply only to the ridge top surface forming section, for example.
[0047] Furthermore, an adjustment plate for adjusting the amount of soil may be provided removably or rotatably at the rear end of the soil supply section for the side of the ridge or the soil supply section for the top of the ridge.
[0048] In addition, one or more intermediate soil supply sections, such as a ridge shoulder soil supply section that supplies soil from the embankment side toward the ridge shoulder formation section, may be provided between the ridge side soil supply section and the ridge top surface soil supply section, at a height intermediate between the two.
[0049] Furthermore, a sprinkler device (water supply means) may be provided that sprinkles water onto the ridge forming body and the soil, for example, to adjust the moisture content of the embankment. [Explanation of symbols]
