And a ridge forming body (disk portion) 4 for forming ridges.

  The ridge forming body 4 is formed in a truncated cone shape (including a substantially truncated cone shape) to form a slanted ridge side surface of a new ridge by compacting the embankment by the fill body 3 while rotating in the rotation direction. The body 6 and the heel side surface forming body 6 provided on the reduced diameter end side of the heel side surface forming body 6 are rotated integrally with the heel side surface forming body 6 and the embankment by the embankment body 3 is compacted to form a horizontal surface of the heel surface of the new heel. It has a cylindrical shape (including a substantially cylindrical shape) to form the upper surface forming body 7. In addition, the peripheral speed of the hook forming body 4 is faster than the traveling speed of the tractor so that the hook forming body 4 rotates in a slip state with respect to the hook side surface and the hook upper surface.

  Further, the hammer coater 1 includes a bank body cover body 8 that covers the bank body 3, an upper surface milling body 9 that scrapes the upper surface portion of the main fence while rotating in a predetermined direction in front of the bank body 3, and the seam forming body 4. And a wrinkle forming body cover body (not shown).

  As shown in FIG. 1, the airframe 2 has a machine frame 11 that is detachably connected to a three-point link portion at the rear of the tractor. The machine frame 11 has a shaft holding portion 12, and an input shaft (not shown) is rotatably provided on the shaft holding portion 12. The input shaft is connected to a PTO shaft of a tractor (not shown) via a joint.

  Further, a movable machine frame 15 that rotatably supports the embankment body 3 and the ridge forming body 4 is connected to the machine frame 11 via a connecting means 16. The movable machine frame 15 is movable in the horizontal direction with respect to the machine frame 11 based on the operation of a cylinder 17 that is a plurality of extendable elastic bodies. For this reason, the upper surface scraping body 9, the embankment body 3, and the ridge forming body 4 are arranged in order from the front during the forward operation by the paddle coater 1, but are reversed 180 degrees in the reverse direction at the corner of the field. It becomes.

  Further, the movable machine frame 15 includes a bank body holding part 18 and a ridge forming body holding part 19, and the bank body 3 is rotatably provided on the bank body holding part 18. 4 is rotatably provided.

  The embankment body 3 is used for embankment that is detachably attached to a tilling shaft 21 that is a rotating shaft in the front-rear direction that is rotated by power from the input shaft side of the machine body 2 and a plurality of claw holder portions 22 of the tilling shaft 21. The tillage claw 23 is provided.

  The ridge forming body 4 has a left and right rotation shaft 26 that is rotated by power from the input shaft side of the machine body 2, and together with the rotation shaft 26, a truncated cone-shaped ridge side surface forming body 6 and a cylindrical ridge upper surface forming body. Reference numeral 7 denotes a rotation center axis X in the horizontal direction, which is the horizontal direction.

  As shown in FIGS. 1 to 3, the heel side surface forming body 6 is arranged side by side in a state of being close to each other in the rotational direction of the heel side surface forming body 6, and includes a plurality of at least two kinds of different sizes. There are two plate-shaped side surface forming plates (face plates), that is, eight types of fan-shaped side surface forming plates 31 and 32 having different central angles (fan central angles), for example.

  That is, the heel side surface forming body 6 includes a large face plate 31 which is a fan-shaped side face forming plate having a central angle α and a central angle smaller than the central angle α of the large face plate 31. each of the large-surface plate 31 and the small-surface plate 32 is a fan-shaped side surface forming plate having the shape of a fan having β. During the rotation of the heel side surface forming body 6, the embankment by the embankment body 3 is pushed in on the rear side in the rotation direction and compacted.

  The central angle α of the large face plate 31 is 55 °, for example, and the central angle β of the small face plate 32 is 35 °, for example. Therefore, the plurality of face plates 31 and 32 are not arranged at equal intervals in the circumferential direction, and the intervals differ depending on the size of the central angle.

  The plurality of (for example, eight) face plates 31 and 32 are connected to each other in the rotation direction of the side surface forming body 6 by a connecting plate 33 which is a connecting member, and have a predetermined truncated cone shape. It is an ordering drum.

  The connecting plate 33 has a longitudinal shape, and includes a flat plate portion 33a on both ends in the width direction, and a curved plate portion 33b having a U-shaped cross section that connects the flat plate portions 33a together. One flat plate portion 33a is fixed to the inner surface of the front end portion in the rotational direction of one of the face plates 31 and 32 of the adjacent face plates 31 and 32 by welding, and the other flat plate portion 33a is the adjacent face plates 31 and 32. The other face plates 31 and 32 are fixed to the inner surfaces of the rear end portions in the rotational direction by welding.

  As is clear from FIG. 2, at least one of one face plate 31, 32 (that is, the large face plate 31 or the small face plate 32) and two other face plates 31, 32 adjacent to each other in the rotational direction ( For example, only one of them is different in size from the one face plate 31, 32. That is, three face plates of the same size are not arranged in succession in the rotation direction. For example, two large face plates 31 and two small face plates 32 are alternately arranged in the rotation direction.

  Here, each of the face plates 31 and 32 is made of, for example, a metal plate such as stainless steel, and both are fan-shaped (including substantially fan-shaped) having the same radial dimension and slightly protruded so that the outer surface side is convex. It is formed in a curved surface and is arranged radially about the rotation center axis X. And the part located in the rotation direction rear side among the outer surfaces (surfaces in contact with the embankment) of the face plates 31 and 32 is a working surface (pressing surface) 34 that pushes the embankment by the embankment body 3 and compacts it. Yes.

  Further, the side surface forming body 6 is formed between the face plates 31 and 32 adjacent to each other in the rotation direction of the side surface forming body 6, that is, between the large face plate 31 and the large face plate 31, and between the small face plate 32 and the small face plate 32. In addition, a step 35 is formed between the large face plate 31 and the small face plate 32 so that the front side in the rotational direction becomes higher. Each step 35 has a longitudinal shape along the radial direction of a virtual circle centered on the rotation center axis X in a side view, and has a height in the normal direction of the outer peripheral surface of the truncated cone-shaped side surface forming body 6. Has dimensions (height difference).

  As shown in FIG. 5, the height dimension of the stepped portion 35 between the face plates 31 and 32 adjacent to each other (the rear end in the rotation direction of the face plate and the front end in the rotation direction of the face plate adjacent to the face plate in the rotation direction rearward). Is set in accordance with the size of the face plates 31 and 32 on the rear side in the rotational direction of the two adjacent face plates 31 and 32. In other words, the height difference, which is the height dimension of the stepped portion 35 between the face plates adjacent to each other, is large when the center angle of the face plate on the rear side in the rotational direction of the double-sided plates is large, and the rotational direction of the double-sided plates is The smaller the central angle of the rear face plate, the smaller.

  More specifically, the face plates 31 and 32 are disposed such that the distance from the rotation center axis X of the side surface forming body 6 gradually increases from the rotation direction front end toward the rotation direction rear end, and The height dimension of each step portion 35 is set according to the size of the face plates 31 and 32 on the rear side in the rotation direction so that the distance from the rotation center axis X at the front end in the rotation direction of each face plate 31 and 32 is constant. ing. For this reason, the distance from the rotation center axis line X of the rotation direction rear end of each faceplate 31 and 32 is not constant.

  As is apparent from FIG. 5, the front ends in the rotational direction of the face plates 31 and 32 are positioned on the reference plane A where the distance from the rotation center axis X is constant. For example, the height dimension HL of the step portion 35 between the large face plate 31 and the large face plate 31 adjacent to each other is larger than the height dimension HS of the step portion 35 between the large face plate 31 and the small face plate 32 adjacent to each other.

  Further, as is clear from FIGS. 4A to 4C, the height dimension H1 on the center side of each stepped portion 35 is larger than the height dimension H2 on the outer peripheral side. The center side height dimension H1 and the outer peripheral side height dimension H2 may be the same.

  Further, as shown in FIG. 3 and the like, the heel side surface forming body 6 has a short cylindrical truncated cone base member 36 and a boss member 37 fixed to the inner surface side of the base member 36. Yes. And the edge part of the center side of each faceplate 31 and 32 is being fixed to the base member 36 by welding. The rotation shaft 26 is inserted and fixed in the shaft insertion portion 38 of the boss member 37. Further, the upper surface forming body 7 is detachably attached to the boss member 37.

  Next, the operation and the like of the wrinkle coater 1 will be described.

  When the coater 1 is moved in the advancing direction by traveling of the tractor in a state where the coater 1 is connected to the rear part of the tractor, the upper surface scraping body 9 scrapes the upper surface portion of the main fence, and the embankment body behind the advancing direction 3 cultivates the soil of the paddy field and the former paddy and raises the cultivated soil onto the former paddle, and the fillet formed by the banking body 3 is compacted while the paddle forming body 4 rotates behind the traveling direction to form a new paddle.

  At this time, the large surface plate 31 and the small surface plate 32 of the heel side surface forming body 6 of the ridge forming body 4 rotate around the rotation center axis X while the embankment by the embankment body 3 is applied to the acting surface 34 on the outer surface on the rear side in the rotation direction. It is pushed into the main fence side and compacted to form a new side face, but the soil pressing interval by the face plates 31 and 32 which are these side face forming plates is not a constant interval, but depends on the size of the central angle of each face plate Change.

  And according to such a plastering machine 1, at least two types of face plates 31 and 32 of different sizes push the embankment by the embankment body 3 on the rear side in the rotational direction, so Differently, the pressing interval of the soil by the face plate is not constant, and as a result, stable padding work can be performed under various field conditions regardless of the field conditions such as soil conditions such as dry fields and wet fields. 1 versatility is improved.

  That is, for example, for dry soil, it can be strongly tightened with the large face plate 31, and by the step-by-step ridge forming that is lightly tightened with the small face plate 32 and then strongly tightened with the large face plate 31, it is strongly resistant to collapse. In addition, the presence of the face plate 32 can reduce the scraping of the surface of the mold once formed against the wet soil, and a strong new collapse can be formed.

  In addition, at least one of the two other face plates 31 and 32 adjacent to the one face plate 31 and 32 in the front-rear direction is different in size from the one face plate 31 and 32. Therefore, more stable glazing operation can be performed.

  Furthermore, since the saddle-side surface forming body 6 has only two types of face plates 31 and 32 having different sizes, assembly and the like are easy as compared with a configuration having three or more types of face plates.

  In addition, in the coater 1, the height dimension of the stepped portion 35 between the adjacent side surface forming plates is set according to the size of the rear side surface forming plate in the rotational direction of the both side surface forming plates. For example, as in the second embodiment shown in FIG. 6, the step between adjacent side surface forming plates (face plates 31 and 32) is not limited to the above-described configuration (configuration based on the rear side plate). A configuration in which the height dimension of the portion 35 is set in accordance with the size of the front side surface forming plate on the front side in the rotation direction of the both side surface forming plates (configuration based on the front side surface plate) may be employed.

  In the configuration shown in FIG. 6, the face plates 31 and 32 are disposed such that the distance from the rotation center axis X of the side surface forming body 6 gradually increases from the front end in the rotation direction toward the rear end in the rotation direction. In addition, the height of each step 35 is set according to the size of the front face plates 31 and 32 in the rotation direction so that the distance from the rotation center axis X of the front end in the rotation direction of each face plate 31 and 32 is constant. Has been. For this reason, the distance from the rotation center axis line X of the rotation direction rear end of each faceplate 31 and 32 is not constant.

  As is apparent from FIG. 6, the front ends in the rotational direction of the face plates 31 and 32 are located on the reference plane A where the distance from the rotation center axis X is constant. For example, the height dimension HL of the step portion 35 between the large face plate 31 and the small face plate 32 adjacent to each other is larger than the height dimension HS of the step portion 35 between the small face plate 32 and the small face plate 32 adjacent to each other.

  Further, the height dimension of the stepped portion 35 is set according to the size of the side surface forming plate so that the distance from the rotation center axis X of the front end in the rotation direction of each side surface forming plate is constant. For example, as in the third embodiment shown in FIG. 7, the rear end in the rotational direction of each side surface forming plate (face plates 31 and 32) is used to suppress vertical vibration of the side surface forming body 6 or the like. The height dimension of each stepped portion 35 may be set according to the size of the heel side surface forming plate so that the distance from the rotation center axis X is constant.

  In the configuration shown in FIG. 7, the face plates 31 and 32 are disposed such that the distance from the rotation center axis X of the side surface forming body 6 gradually increases from the front end in the rotation direction toward the rear end in the rotation direction. In addition, the height dimension of each step 35 is the rear face plate 31 in the rotational direction so that the distance from the rotation center axis X of the rear end (high portion) of the face plates 31 and 32 in the rotational direction is constant. , 32 is set according to the size. For this reason, the distance from the rotation center axis X of the rotation direction front end (part with low height) of each face plate 31 and 32 is not constant.

  As is apparent from FIG. 7, the rear end in the rotation direction of each of the face plates 31 and 32 is located on a reference surface (outer peripheral surface of the side surface forming body) A having a constant distance from the rotation center axis X. . For example, the height dimension HL of the step portion 35 between the large face plate 31 and the large face plate 31 adjacent to each other is larger than the height dimension HS of the step portion 35 between the large face plate 31 and the small face plate 32 adjacent to each other.

  Further, for example, as in the fourth embodiment shown in FIGS. 8A and 8B, each of the face plates 31 and 32 may be detachably attached to the outer surface side of the base member 36 by bolts 41.

  In the configuration shown in FIG. 8, the base member 36 is formed in a truncated cone shape larger than that of FIG. 3, and a plurality of face plate mounting holes 42 are formed in the base member 36. A plurality of nuts 43 are fixed to the inner surfaces of the face plates 31 and 32 by welding. The face plates 31 and 32 are individually attached to the base member 36 by inserting the bolts 41 through the holes 42 of the base member 36 and screwing them into the nuts 43. For this reason, the connecting plate 33 is unnecessary, and the face plates 31 and 32 can be individually replaced. For example, although not shown, a configuration in which a drum-like member in which adjacent face plates are connected by a connecting member is detachably attached to the base member 36 may be used.

  Also, for example, as in the fifth embodiment shown in FIG. 9, both one side surface forming plate (for example, the large surface plate 31 or the small surface plate 32) and the other side surface forming plate adjacent to the front and rear in the rotational direction. However, the structure which differs in the magnitude | size of the central angle from the one side surface formation board may be sufficient. In this configuration, the large plate 31 and the small plate 32 are alternately arranged.

  Further, as in the sixth embodiment shown in FIG. 10, for example, the saddle-side surface forming body 6 has nine types of fan-shaped saddle-side surface forming plates having two different central angles, that is, for example, three sheets. The large surface plate 31 and the six small surface plates 32 may be used.

  In addition, as in the seventh embodiment shown in FIG. 11, for example, the saddle-side surface forming body 6 has nine fan-shaped saddle-side surface forming plates having three different central angles, that is, for example, three sheets. The large surface plate 31, the three small surface plates 32, and the three medium surface plates (side surface forming plates) 46 may be used.

  Furthermore, as in the eighth embodiment shown in FIG. 12, for example, the saddle-side surface forming body 6 has four types of fan-shaped saddle-side surface forming plates having different central angles, that is, for example, two sheets. The large surface plate 31, the two small surface plates 32, the two middle surface plates 46, and the two extra large surface plates (side surface forming plates) 47 may be used.

  Also, for example, although not shown in the figure, there are five types of fan-shaped side surface forming plates with different central angles, and eight types of eight fan-shaped with different central angles. The structure etc. which have a heel side surface formation board may be sufficient, and what is necessary is just the structure which has a plurality of heel side surface formation board by at least 2 types from which a magnitude | size mutually differs.

  Note that the number of side surface forming plates which are trimming plates is preferably 6 to 9, for example, but other numbers may be used, and the central angle of each side surface forming plate having a fan shape is 20 ° to 72. °, preferably 30 ° to 60 °.

  Further, the side surface forming plate may be, for example, a rectangular shape in addition to the fan shape, or may be an elastic plate that can be elastically deformed, for example.

  Furthermore, regarding the height dimension of the stepped portion between the side surface forming plates adjacent to each other in the rotation direction, for example, the height dimension on the outer peripheral side (hem side) of the stepped portion is made constant regardless of the size of the side surface forming plate. Only the height dimension on the center side of the stepped portion may be changed in accordance with the size of the side surface forming plate.

  In addition, although several embodiment of this invention and its modification were demonstrated, it is also possible to combine the said embodiment and modification suitably in the range which does not deviate from the summary of this invention.
