  Next, referring to FIG. 8, the above-described traveling wheels H1, H2, the beating surface hitting means 30, the slope forming body 40A and the upper surface forming body 40B, and the tilling blades R1, R2, R3, etc. are driven. The drive system DO to be described will be described. First, the output from the engine E to the saddle molding 40 is sprocket 2, chain C1, sprocket with claw clutch 3, shaft 4, chain C2, sprocket 5, 6, chain C3, sprocket 7, 7A, chain C4, sprocket. 9B is transmitted to the rotating shaft 50. The traveling wheels H1 and H2 travel by turning on / off the power with the sprocket 3 with a claw clutch.

  Further, the driving wheels H1 and H2 are driven by the output from the engine E from the sprocket 9A on the drive shaft 50 through the chain C5 to the sprocket 11C, sprocket 11D, chain C6 and sprocket 10C of the idle shaft 11B on the shaft 11A. The chain C7 or C8, the sprocket 11E or 11F, and 11G or 11H, the chain C9 or C10 are further transmitted from the sprocket 10A with a claw clutch or the sprocket 10B with a claw clutch at both ends of the drive shaft 35. To the sprockets 12A and 12B. And it is transmitted to the traveling wheels H1, H2 attached to the outer ends of the first cylindrical portions 50A, 50B to which the sprockets 12A, 12B are attached. The sprocket 10A with a claw clutch has a small diameter, the sprocket 11E has a large diameter for a low speed, the sprocket 10B with a claw clutch has a large diameter, and the sprocket 11F has a small diameter for a high speed. , H2 can be rotated at different speeds.

  In addition, the transmission of power from the rotary shaft 50 to the rotary shaft 46 is performed by rotating a chain 49 between a sprocket 47 provided on the rotary shaft 50 and a sprocket 48 provided on the rotary shaft 46 so that the sprocket 48 is always free to rotate. Is transmitted to the rotary shaft 46 by an on / off operation of the clutch means 55.

  Further, the output to the tilling blades R1, R2 is transmitted by the rotor shafts of the sprocket 13, the chain C10, and the sprocket 14 that are transmitted by turning on and off the claw clutch of the sprocket 7A, and the tilling blade R1 mounted on the rotor shaft. , R2 and R3 are rotationally driven. This on / off operation is performed by turning on / off the pawl clutch of the sprocket 7A. Further, the output to the beating surface hitting means 30 is transmitted by the sprocket 15 to which power is transmitted when the claw clutch of the sprocket 7A is turned on and off, and the drive shaft 33 connected to the upper face hitting means 30 by the chain C11 and the sprocket 16 is transmitted. To drive. This off operation is performed by turning on and off the pawl clutch of the sprocket 7A.

  The operation will be described based on the above configuration. First, the prime mover E is started so that the saddle molding machine 100 can run, the saddle surface striking means 30 and the saddle molding 40 are driven, and the inner side of the saddle 20 is moved in the traveling direction A. At this time, as shown in FIG. 9, the tiller blade R1 and the tiller blade R2 at the front lower part dig up near the paddle forming portion 20 and scrape the soil 20A on the slope 20D and the upper surface 20C. Further, the surface of the old slope face 20D is scraped off by the tilling blade R3. As shown in FIG. 10, the soil 20 </ b> A raised on the upper surface 20 </ b> C of the ridge forming portion 20 is compacted by the ridge surface beating means 30 disposed behind the tilling blade R <b> 1. That is, when the hitting plates 30A and 30B swing and move on the upper surface and slope of the ridge, the soil 20A raised on the upper surface is flattened and solid, and the soil of the slope that follows is flatly pushed. Solidify. Subsequently, as shown in FIGS. 11 and 12, the sloped surface molded body 40 </ b> A and the top surface molded body 40 </ b> B of the ridged molded body 40 disposed behind the ridged surface striking means 30 roll in the traveling direction A, It proceeds while pressing the soil 20A built up on the upper surface.

  The slope molded body 40A has a conical face body attached to the distal end side of the rotating shaft 46 via a mounting bracket 78, and the molding force on the slope of the flange 20 is actuated by rotation to be securely compacted. Further, the upper surface molded body 40B also has a frustoconical appearance, and the molding force on the upper surface of the ridge works and is securely compacted. As a result, the slope 20D of the ridge is smooth and beautifully finished, and a ridge that does not easily collapse is formed quickly.

  Further, in the scissor forming machine of the present invention, the scissors compact 40, that is, the sloped compact 40A and the top compact 40B, is provided at a position eccentrically above the drive shaft 50 of the traveling wheel and is driven by the drive shaft 50. Rotational force is transmitted by the clutch means 53 for turning on / off the transmission of the motor, and the position can be adjusted up and down around the drive shaft 50.

  That is, as shown in FIG. 7, when it is desired to move the saddle molding 40 to the maximum lowered position, the operation portion 59 is pulled up to release the guide roller 58, and the crank arm 43 is lowered to the lowest position of the guide guide plate 56. It moves to 1 position (a), returns the operation part 59, and locks the guide roller 58 in the said guide groove. As a result, the sloped surface molded body 40A of the ridge formed body 40 is disposed at the position of the solid line in the drawing, and the height of the ridge formed is the lowest. At this time, as shown in FIG. 6, in the clutch means 53, the clutch lever 71 is pushed by the guide rail 75, and the clutch shifter 72 shifts to the left side in the figure to automatically engage the clutch by the driving force of the drive shaft 50. Rotational force is transmitted. Further, when forming a ridge higher than this, the operation unit 59 is pulled up to make the guide roller 58 free, and the crank arm 43 is moved to the second position (b) slightly above the guide guide plate 56 to operate the operation unit. 59 is returned to lock the guide roller 58 in the guide groove. As a result, the sloped surface molded body 40A of the ridge molded body 40 is disposed at the position of the broken line in the figure, and the height of the molded ridge increases. The clutch means is in the same state as described above, and is automatically rotated.

  Further, when it is desired to raise and temporarily stop the saddle molded body 40, it moves to the third position (c), and when it is desired to completely raise and stop when not in use, it moves to the fourth position (d). Let In this case, in the clutch means 53, the clutch lever 71 is disengaged from the guide rail 75, and the clutch shifter 72 shifts to the right side in the figure to automatically turn off the clutch so that the rotational force is separated from the driving force of the drive shaft 50. It is not transmitted. In the case of the above-described embodiment, the guide groove is switched to the upper and lower stages when in use. However, the height can be adjusted in multiple stages by increasing the number of guide grooves. In the case of the above-described embodiment, the automatic switching type using the clutch lever and the guide rail is shown as the clutch means. However, instead of this, the clutch drive type having an independent operation unit, that is, the clutch approach is shown. It is also possible to adopt a method in which the above operation is performed with a clutch lever via a wire.

  As shown in FIG. 16, in the conventional wrinkle forming apparatus, the outer diameter edge of the conical surface 52A constituting the inner rotary plate (conical rotating body) 52 for forming the slope 20D of the reed 20 is formed linearly. If this is the case, the straight portion of the outer diameter edge cannot press down the bottom surface portion 20E of the slope 20D, and the slope is likely to collapse. Moreover, the earthing device (especially walking type hail forming device) which consists of a tilling blade which supplies soil to the hail forming unit 20 continuously in a raised state is a traveling direction of the machine body when the soil is brought closer to the hull forming unit side with the tilling blade. On the other hand, the force that tilts the light aircraft to the heel side works and tilts it. As shown in FIG. 16, the original upper surface 20C and slope 20D are shown by the two-dot chain line. However, since the machine body tilts toward the heel forming portion, the rotating body 52B provided at the center of rotation of the conical rotating body 52A constituting the heel forming apparatus is inclined low, and this tip tilts the top surface 20C of the heel to form a concave groove. 20C 'is formed. In addition, the conical rotating body 52A that forms the slope 20D of the ridge also presses the upper side of the slope strongly and does not push the lower side so much, so a firm slope is not formed. For this reason, there is a problem that the slope side of the upper surface becomes high, and rainwater flows down to the outside of the upper surface, that is, the outside of the eaves, and is easily broken by rainwater.

  On the other hand, in the scissor forming machine of the present invention, as shown in FIGS. 11 and 12, the upper surface molded body 40B has a tapered surface 40E whose outer peripheral surface is slightly narrowed on the tip side, and the taper angle is about 10 °. Therefore, even if the airframe is inclined to the slope side, the upper surface 20C is finished by being slightly inclined to the horizontal posture or the inside of the heel. Thereby, rainwater flows into the edge side of the kite, and a kite that is not easily broken by the rainwater is quickly formed. Further, as shown in FIG. 13, the upper surface molded body 40A is obtained by cutting a hexagonal cross section rotation shaft 50 as a rotation axis into short pieces, and providing a female screw 50C on the shaft end surface. The first taper portion 40C ′ disposed at the boundary between the upper surface and the slope of the heel and the second taper portion 40T at the tip of the first taper portion are integrally formed and screwed to the female screw 50C with the bolt B0. It can also be attached. The surface angle between the sloped molded body 40A and the first taper portion 40C ′ is set to about 20 °, and the second taper portion 40T is set to a taper angle of about 10 ° with respect to the rotation center O. This is set from an empirical rule that the inclination of the aircraft to the heel side is around 10 °. The taper angle is not limited to the above and is arbitrary. Further, the first tapered portion 40C ′ may be formed in an R shape instead of a linear shape.

  When the first tapered portion 40C ′ is attached to the boundary between the upper surface and the slope of the collar on the rotation axis of the sloped molded body 40A, and the second tapered portion 40T is attached to the tip, The boundary between the upper surface 20C and the slope 20D can be finished in an arc shape by the first tapered portion 40C ′. Even if the aircraft tilts toward the heel side, the second tapered portion 40T is in a horizontal posture and the upper surface 20C is finished in a horizontal state as indicated by a two-dot chain line, so that rainwater does not collect on the upper surface and the boundary from the upper surface of the heel. Smoothly flows into the slope through the arcuate surface of the. As a result, rainwater does not collect on the upper surface, but flows smoothly from the upper surface of the kite to the slope through the boundary arc-shaped surface. Therefore, it is possible to form a ridge that does not collapse due to rainwater.

  As described above, the scissor forming machine 100 of the present invention first operates the striking surface striking means 30 for flatly forming the top surface 20C and the slope 20D of the piled scissors forming portion 20, and then further increases the slope 20D. Since the sloped molded body 40A formed flat and the top molded body 40B formed flat on the upper surface 20C of the ridge 20 are allowed to act, the ridge 20 is increased even if the outer diameter of the upper molded body 40B is reduced. Can be molded. This is because even if the upper surface 20C of the ridge is piled up with a large pile and has unevenness, it can be first struck and compacted by the ridge surface striking means 30, and the upper surface molded body 40B can be rubbed with the upper surface 20C. It can be finished with a smooth and clean top surface. Further, the slope 20D can be finished in advance by the hitting plate 30B of the saddle hitting means 30 so that the tightening is good and the finish can be smooth and clean. Furthermore, since the slope molding 40A is formed in the shape of a truncated cone, the bottom surface portion 20E of the slope surface of the ridge 20 is firmly pressed without any gap, so that the soil 20A of the bottom surface portion 20E of the slope surface 20D is difficult to collapse. Therefore, by taking the above-described work mode, the work can be performed at the normal traveling speed of the towing vehicle 1A, and therefore, the work for forming the rod 20 can be performed speedily and efficiently. Further, the sloped surface molded body 40A is provided at a position deviated upward from the drive shaft of the traveling wheel, is transmitted with a rotational force by the clutch means 53 for turning on / off the transmission of the drive force of the drive shaft, and vertically Therefore, it is possible to easily change the height of the ridge by raising and lowering the upper surface molded body and the slope molded body while having a simple configuration.

  As described above, according to the embodiment of the present invention, the following effects can be obtained. First, in the scissors forming machine 100, scissor surface hitting means 30 for forming the top surface 20C and the slope 20D of the scissors forming portion 20 flat, and the slope 20D of the scissors forming portion 20 and the bottom surface 20E are formed flat. Since the upper surface molded body 40B is separately installed and operated, the heel is high, and the soil 20A of the bottom surface portion 20E of the slope 20D is evenly pressed by the outer peripheral edge 40I of each pressing piece 40C and is not easily collapsed. The top surface 20C and the slope 20D of the ridge-forming part 20 can be smooth and beautifully finished. In addition, the wrinkle forming work can be performed quickly and efficiently. Further, the height of the ridge can be arbitrarily adjusted with a simple configuration without exchanging the upper surface molded body and the sloped surface molded body.

  In addition, although the scissors molding 40 in the said 1st Embodiment was made into the shape of a conical body, it is not limited to this. For example, a conical surface body may be formed by arranging a plurality of (e.g., eight) conical surface-shaped plates in parallel with the end portions overlapped. Also in this case, since the slope is formed flat by striking with the saddle face striking means, it can be finished beautifully only by stroking with the multi-plate conical face. Moreover, it is good also as pyramid surface shape instead of said conical surface shape, and as shown to FIG. 14, FIG. 15, 2nd Embodiment made into a pyramid surface shape and impeller shape. It is also possible to use the cocoon molding machine 200. That is, a large-diameter pyramidal surface body 40 </ b> A is mounted in an impeller shape on the outer peripheral portion 63 </ b> A of the first cylindrical portion 63 fitted to the rotating shaft 46. That is, the sloped body 40A includes a plurality of (six to eight, preferably eight in the drawing) resin-made flat plate-shaped pressing pieces 40C on the rotating shaft side of the first cylindrical portion 63 with bolts B. Adhering to the outer peripheral portion 63A, the adjacent surfaces on the outer peripheral side 40D of each piece are combined in a predetermined inclination angle so that the rear side G in the rotation direction protrudes toward the slope 20D, and are fixed in an impeller shape. Further, the upper surface molded body 40 </ b> B is disposed on the outer periphery of the second cylindrical portion 65. That is, the upper surface molded body 40 </ b> B has a frustoconical appearance, and a tapered surface 40 </ b> E made of resin whose tip end side is slightly narrowed is attached to the outer peripheral portion 65 </ b> A of the second cylindrical portion 65. Although the taper angle is arbitrary, it is preferably about 10 °.

  Since the above-mentioned slope molding 40A combines a plurality of pressing pieces 40C so that the rear side G of the rotation direction protrudes toward the slope 20D, the slope molding 40A to the slope of the ridge 20 is 40A. This intermittent molding force is generated a plurality of times during this one rotation, so that it is surely compacted. In addition, since the slope molded body 40A having the outer peripheral edge 40I projecting in an arc shape is separately installed and operated, the bottom face portion 20E of the slope face of the ridge 20 and the whole slope face can be firmly pressed and formed high. In addition, the upper surface 20C can be formed flat in a horizontal state. In particular, since the outer peripheral edge 40I of each pressing piece 40C of the sloped surface molded body 40A is formed in a truncated cone shape, the cultivated soil enters between the ridge forming surface and the truncated pyramid-shaped pressing piece to form an impeller shape. Since the outer periphery of the pressing piece is formed in a truncated cone shape, the soil does not escape to the groove side, and it is tightened from the bottom of the slope that has fallen to the bottom of the slope. It can be pressed up. As a result, the soil is firmly clamped to the slope, and the slope does not collapse. As a result, the slope 20D of the ridge is smooth and beautifully finished, and a ridge that does not easily collapse is formed quickly.

  Moreover, although the said embodiment gave and demonstrated the example of the straw molding machine which shape | molds the paddy rice paddy, it can replace with this and can be applied to shaping | molding of paddy. That is, in the apparatus of the first embodiment, the rotary shaft 50, the drive shaft 33, and the rotary shaft 46 are extended to the left side in the drawing, and the ridge-formed body 40 and the ridge surface hitting means 30 are provided on the opposite side of the machine body. Can do. Since other configurations are the same as those in the first embodiment, the same portions are denoted by the same reference numerals and description thereof is omitted. Such a thing also falls in the technical scope of the present invention.

  By adopting such a configuration, it can be used for the work of making a ridge by making a groove in the house, and at that time, the upper surface and the slope of the ridge can be firmly tightened to form an upper ridge. Other operations and effects are the same as those in the first embodiment.

  In addition to the above-described configuration, the culvert forming machine, the cultivating blade, which has a slope cultivating blade that scrapes off the old ridge of the cocoon forming portion on the tip side of the cultivating blade on the cocoon forming portion side, Can be a cocoon forming machine characterized in that a cultivating blade that rakes up the cultivated soil to the cocoon-forming part side and a cultivating blade that rakes up the cultivated soil to the side of the anti-molding part are arranged on the left and right. .
