Japanese Patent No. 2564230

  The conventional configuration has the following problems. In other words, in the conventional ridge forming apparatus, the rotating body that holds down the upper surface of the ridge is composed of a small-diameter round shaft. Escape to the upper side and do not hold the earth firmly, and the tightness and flatness of the upper surface of the ridge will deteriorate. This means that extra time is required for the work of forming the ridges, which deteriorates the work efficiency. Moreover, since the said rotary body is a small diameter round shaft, there exists a limit in pressing down the flat top surface with a large unevenness | corrugation flatly. Therefore, as shown in FIG. 21, in order to expand the limit that can cope with the large unevenness of the heel surface 20C, the small-diameter rotating body 52B must necessarily be made large in diameter, which is necessarily the rotating body 52B. This means that the effective dimension of the inner rotary plate 52 that rotates integrally with the conical surface 52A is reduced, resulting in a new problem that the height H0 of the flange 20 is limited to be low. In short, in the conventional ridge forming apparatus, the working speed is slowed down if a high ridge is to be formed, and the outer diameter of the rotating body is increased to ensure that the top surface of the large uneven surface is flat. There was a problem that the height would be lowered.

  In addition, in order to finish the entire slope of the ridges cleanly and firmly, so that the work can be performed speedily, the embankment is struck with a striking plate in advance before it is finished with the sloped molded body, and is in a state of being compacted to some extent. It is possible. However, when the slope is struck hard, the amount of soil becomes small and hard, and when the slope molding is pressed against this, the lower part of the heel is shaved and undercut occurs, making it impossible to finish cleanly and the heel tends to collapse It becomes.

FIG. 14 is an explanatory view showing the positional relationship between the sloped surface hitting plate and the sloped surface molded body.

  The cocoon forming machine 100 of the present invention uses a hand tractor (cultivator) 1 as a towing vehicle 1A. The fuselage F of the towing vehicle 1A is provided with a motor E at the front upper part in the traveling direction A, and the front wheel (double wheel) R0 of the towing car 1A and the vicinity of the ridge forming part 20 are dug up at the front lower part and the slope 20D and the upper surface A tilling work body R comprising a pair of left and right tilling blades R1, R2 that scrapes the soil 20A on 20C and a slope tilling blade R3 that scrapes off the slope 20D of the old tack 20 is provided. In addition, traveling wheels H1 and H2 are provided on the left and right at the rear. The front wheel (double wheel) R0, the pair of left and right tilling blades R1 and R2, and the traveling wheels H1 and H2 can be used for tilling with good left-right balance and the towing vehicle 1A can travel straight.

  That is, the pair of left and right tilling blades R1 and R2 is composed of two each of left and right three pieces, each having six pieces, and by digging up the soil evenly on the slope side and the anti-slope side, a hand tractor (cultivator) 1 aircraft is balanced in a stable posture. Further, the slope tiller blade R3 for scraping the slope 20D of the old tack 20 is attached to the tip side of the tiller blade R1, and is composed of a blade inclined according to the slope angle of the slope. In addition, it is good also as a structure which abbreviate | omits the said slope tilling blade R3, and piles up soil directly on the slope of an old tack with a pair of right and left tilling blade R1, R2. Moreover, although it is the said tilling blade R1, R2, it is not necessarily restricted to the said structure, The 1 side of the tilling blade R2 of the anti-slope side is set so that six sheets of the slope side tilling blade R1 face the slope side. It is good also as a structure which orient | assigned three sheets to the slope side and directed other tillage blade R2 to the slope side. Thereby, more soil can be supplied to the slope side, and the body of the hand tractor (cultivator) 1 can be balanced in a stable posture. Further, the tilling blades R1 and R2 may be attached to the shaft via a cylindrical body, moved in the axial direction and fixed at an arbitrary position with a bolt or the like, and the attachment position may be adjustable. It is needless to say that the tilling blades R1 and R2 can be attached to a plurality of pieces, or can be moved to an arbitrary position. Thereby, more soil can be supplied to the slope side, and the body of the hand tractor (cultivator) 1 can be balanced in a stable posture. Further, the front wheel (double wheel) R0 of the towing vehicle 1A and the rear left and right traveling wheels H1 and H2 can keep the tilling depth by the pair of left and right tilling blades R1 and R2 constant, and thus the height of the rod Can be held constant.

  At the rear part of the tilling blades R1 and R2 in the towing vehicle 1A, there is provided a hook surface hitting means 30 for compacting the soil 20A and the slope 20D piled on the upper surface 20C of the hook forming portion 20. As shown in FIGS. 1 to 4, the saddle-striking means 30 is configured such that a fulcrum O1 at the lower end of the slope-striking plate 30B is rotated by a pin P1 on a lower end of a frame F1 suspended from a support cylinder 31 attached to the body F. It is pivotally supported. The slope striking plate 30B is provided with a top surface striking plate 30A that strikes the top surface at the top. The upper surface striking plate 30A is attached to the sloped surface striking plate 30B so that the height of the upper surface striking plate 30A can be adjusted in accordance with the height of the ridge by means of a plurality of holes and bolts. The upper surface hitting plate 30A may be integrally attached to the slope hitting plate 30B.

  The slope hitting plate 30B and the top hitting plate 30A are connected to a driving system DO (described later in FIG. 7) DO using a prime mover E through an advancing / retracting movement mechanism S in an upper corner portion so as to advance and retreat them. ing. The configuration is such that the lower end of the connecting rod L1, which is pivotally supported by an eccentric pin P on the disc 33A of the drive shaft 33 rotating within the support cylinder 31 and moves up and down as indicated by an arrow (A), is the tip of the connecting rod L2. It is connected at a substantially right angle with a universal joint. The rear end of the connecting rod L2 is pivotally supported by a support shaft P2 attached to the fuselage F, and is integrated with the connecting rod L3 in a vertical posture, as indicated by an arrow (b) with the support shaft P2 as the center of rotation. Is swung. The upper end of the connecting rod L3 is pivotally supported by the upper end of the connecting rod L4 and the support shaft P3 so as to swing the slope hitting plate 30B, and the lower end of the connecting rod L4 is a support shaft on the upper portion of the slope hitting plate 30B. Connected to P4. Thus, the connecting rod L4 moves back and forth in the direction of the axis of the arrow (C), thereby swinging the slope striking plate 30B in the direction of the arrow (2). With such a configuration, the upper surface striking plate 30A and the sloped surface striking plate 30B swing at a predetermined rotation speed in the left-right direction perpendicular to the rod 20 indicated by the arrow (2) with the lower end fulcrum O1 as the center. Is done. Thus, the slope 20D can be struck and compacted simultaneously with the upper surface 20C of the ridge forming portion 20. The function / purpose of the saddle surface hitting means 30 is that, in the next slope molded body 40A, the rotational speed is different between the upper part and the lower part of the saddle forming part 20, and the upper side becomes slower and the pressing degree becomes lower. This is because it is preferable that the upper part and the slope be squeezed to some extent.

  Two large-diameter traveling wheels H1 and H2 are provided on the rear side of the saddle-striking means 30, and the traveling wheel H1 on the saddle side has an axis of a rotating shaft 50 in a direction perpendicular to the traveling direction of the airframe. A stainless steel sloped surface molded body 40A provided at L and a saddle molded body 40 having a stainless steel upper surface molded body 40B for finishing the upper surface 20C of the flange molded portion 20 at the rotation center O are attached. Thereby, the slope molded body 40A and the upper surface molded body 40B are rotationally driven together with the traveling wheels H1 in the traveling direction A of the towing vehicle 1A.

  Further, as shown in FIGS. 5 and 6, the left and right traveling wheels H1 and H2 are mounted on a bearing cylinder 60 fitted to a rotary shaft 50 having a hexagonal cross section and a wheel 61 attached to the outside thereof. The traveling wheels H1 and H2 are connected to a drive system DO (described later in FIG. 7) DO using the prime mover E as a drive source via a chain C5 wound around the sprocket 12 on the bearing cylinder 60. Moreover, the said saddle molded object 40 is arrange | positioned on the outer side of the driving | running | working wheel H1. First, the slope molded body 40A is mounted on the outer peripheral portion 63A of the first cylindrical portion 63 fitted to the rotating shaft 50. That is, the sloped molded body 40A is a combination of a plurality of (preferably 6 to 10 sheets, 8 illustrated) flat plate-like pressing pieces 40C made of stainless steel in a pyramidal shape, and the rotation axis side of which is a bolt B. Are fixed to the outer peripheral portion 63A of the first cylindrical portion 63, and the adjacent surface on the outer peripheral side 40D of each piece is combined at a predetermined inclination angle so that the rear side G in the rotation direction protrudes toward the slope 20D side. The rear side is curved in an R 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 °.

  As shown in FIG. 1, FIG. 5 and FIG. 6, the sloped surface molded body 40A combines the flat plate-like pressing pieces 40C in a truncated pyramid shape so that the rear side in the rotational direction protrudes to the sloped surface side of the flange forming part. In addition, since the rear side is curved in an R shape and the outer peripheral edge 40I of the pressing piece is formed in a truncated cone shape, the cultivated soil enters and accumulates between the ridge forming surface and the truncated pyramid shaped pressing piece, It is pressed by the R-shaped part on the rear side of the shaped pressing piece 40C, and the slope can be finished cleanly without adhesion of soil. Moreover, since the outer peripheral edge side of the pressing piece is formed in the shape of a truncated cone, the accumulated soil can be pressed up sequentially from the bottom without escaping to the groove side. Thereby, the soil 20A of the bottom surface portion 20E of the slope 20D is firmly pressed by the outer peripheral edge 40I of each pressing piece 40C without a gap, and the bottom surface portion 20E does not collapse. Become.

  Further, the drive system DO for driving the traveling wheels H1, H2, the beating surface hitting means 30, the slope forming body 40A, the upper surface forming body 40B, the tilling blades R1, R2, R3 and the like has the following configuration. ing. That is, as shown in FIG. 7, 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, sprockets 5, 6, chain C3. It is transmitted to the rotary shaft 50 by the sprockets 7 and 7A, the chain C4 and the sprocket 9B. The traveling wheels H1 and H2 travel by power on / off operation with the sprocket 3 with a pawl clutch.

  The driving wheels H1 and H2 are driven by an output from the engine E from the sprocket 9A on the rotating 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, sprocket 11E or 11F, and 11G or 11H, 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.

  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 positional relationship between the saddle surface hitting means 30 and the sloped surface molded body 40A is as follows. That is, as shown in FIG. 14, when the sloped surface hitting plate 30B of the saddle face hitting means is moved forward, the lower part thereof is provided at a position away from the lower part of the sloped molded body 40A on the opposite side. Although this distance T varies depending on the viscosity of the soil, etc., a range of 1 to 10 cm is preferable, and in the illustrated case, it is set to 5 cm. As a result, the amount of soil accumulated between the sloped surface hitting plate 30B and the old hammer is increased, and finishing with the sloped molded body 40A is performed while maintaining a soft state. At this time, as shown in FIG. 20, when the saddle-striking means 30 is set in a state of projecting from the sloped molded body 40A, the slope is strongly squeezed by the sloped molded body 40A and then finished. If it tries to do so, the lower part of the slope will be scraped by the slope molding 40A, and an undercut U will occur. This is probably because the amount of soil between the sloped surface and the slope of the ridge is small and hard. Therefore, in the present invention, the sloped surface hitting plate 30B of the saddle face hitting means 30 is provided at a position where the lower part thereof is separated from the lower part of the sloped surface molded body 40A on the side opposite to the saddle side. In this case, since the amount of soil accumulated between the sloped surface striking plate 30B and the old shear is large and kept in a soft state, the bottom of the slope is formed by the slope molding when it is scooped by the slope molded body 40A. It was possible to finish it cleanly without being cut by the body and causing an undercut U.

  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. 8, the tiller blade R1 and the tiller blade R2 at the lower front part dig up near the paddle forming part 20 and scrape the soil 20A to the slope 20D and the upper surface 20C. Further, when the tilling blade R3 is provided, the surface of the old slope face 20D is scraped off. As shown in FIG. 9, 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 FIG. 10, the sloped surface molded body 40 </ b> A and the top surface molded body 40 </ b> B of the ridged molded body 40 arranged behind the ridged surface hitting means 30 roll in the traveling direction A and are stacked on the sloped surface and the top surface. It proceeds while pressing the soil 20A.

  As shown in FIGS. 6 and 10, the slope molding 40A is formed by combining a plurality of pressing pieces 40C so that the rear side G of the rotation direction protrudes toward the slope 20D. Intermittent forming force of the sloped molded body 40A to the slope of this time is generated a plurality of times during this one rotation, and it is surely compacted. Further, the sloped surface molded body 40A combines the flat pressing piece 40C in a truncated pyramid shape with the rear side in the rotation direction protruding toward the slope side of the flange forming part, and the rear side is curved in an R shape. Since the outer peripheral edge 40I is formed in a truncated cone shape, the cultivated soil enters and accumulates between the ridge forming surface and the truncated pyramid-shaped pressing piece, and is pressed by the R-shaped portion on the rear side of the flat pressing piece 40C. , Can finish the slopes cleanly without adhesion of soil. In addition, since the outer peripheral edge of the pressing piece is formed in the shape of a truncated cone, the soil does not escape to the groove side, but the soil that has fallen into the bottom surface of the slope is tightened from below and is sequentially pressed upward. As a result, the soil is firmly compacted to the slope, and the bottom face does not collapse. Thereby, the slope 20D of the ridge is smooth and clean, and the ridge that does not collapse easily can be formed speedily.

  As shown in FIG. 21, 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. 22, 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 100 of the present invention, as shown in FIGS. 10 and 11, 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 mm. Since it is set to °, even if the airframe is tilted to the slope side, the upper surface 20C is finished by being slightly tilted 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.

  Further, when the slope-striking plate 30B of the saddle-striking means is advanced, its lower portion O1 is provided at a position away from the bottom of the slope-shaped molded body 40A on the opposite side. As a result, the amount of soil accumulated between the beveling plate 30B and the old reed is increased, and a soft state can be maintained. It can be finished neatly without being cut by the body and causing undercut U.

  As described above, according to the present embodiment, 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.

  In addition, since the plurality of pressing pieces 40C are provided in the shape of the impeller on the slope molding 40A, the intermittent pressing force of the slope molding on the slope 20D of the rod 20 is applied several times during this one rotation. Can occur, and can be compacted securely and can form a slope that does not collapse easily.

  Further, the upper surface molded body 40B is a resin tapered surface 40E whose tip side on the outer peripheral surface is slightly narrowed, and the taper angle is set to about 10 °. Even if it is tilted, the upper surface 20C is finished in a horizontal posture or slightly tilted to the inside of the ridge. Thereby, rainwater flows into the edge side of the kite, and the upper surface of the kite which cannot be easily broken by rainwater can be formed.

  Further, since the lower surface of the slope-striking plate 30B of the saddle-striking means is provided at a position farther away from the bottom of the sloped molded body 40A when it is advanced, the slope-striking plate 30B and the old hammer are provided. Since the amount of soil accumulated between the two and the surface can be kept soft, the lower part of the slope is scraped by the sloped molded body and the undercut U is generated when it is stroked by the sloped molded body 40A. It can be finished beautifully. Therefore, collapse of the ridge due to water leakage from this portion can be prevented.

  Next, a second embodiment of the present invention will be described with reference to FIGS. In the case of the first embodiment, the cultivation work body R is cultivated at the bottom of the field adjacent to the old ridge and soil is placed in the ridge forming section, which is used as a surface-tapping means, a slope-shaped molded body, and an upper-surface molded body. In the configuration finished by the above, the slope striking plate of the beating surface striking means has a structure in which the lower part is provided at a position away from the lower part of the sloped molded body on the side opposite to the receding side. In the case of the form, the tilling work body R is plowed on the bottom of the field adjacent to the old ridge and the old ridge slope, and the soil is placed on the ridge forming section 20, and this is applied to the ridge surface hitting means 30, the slope formed body 40 A and the upper surface. In the configuration finished by the molded body 40B, when the sloped surface hitting plate 30B of the saddle surface hitting means 30 is advanced, its lower portion O1 is provided at the same position as the lower part of the sloped surface molded body 40A or at a position away from the opposite side. It is a configuration. As shown in FIG. 15, the tilling work body R projects the tilling blade R1 to the slope portion of the old rod, plows the entire portion, and lays soil.

  In addition, as shown in FIG. 16, the tilling work body R causes the tilling blade R1 to protrude to the slope portion of the old tack, and the tilling blade R4 on the tip side has a short size, and it is tilled obliquely along the slope. It will be used to fill the soil. In this case, the lower surface of the sloped surface hitting plate 30B of the saddle surface hitting means only needs to be provided at the same position as the lower part of the sloped surface molded body or at a position away from the saddle side. This is because the amount of soil accumulated between the beating plate 30B and the old fence can be increased and kept soft. Other configurations are the same as those in the first embodiment, and the description thereof will be omitted. According to the present embodiment, the tilling work body R is plowed on the bottom of the field adjacent to the old paddle and the old paddle slope part, and the soil is deposited on the paddle forming part, so that it accumulates between the slope striking plate and the old paddle. With the amount of soil increased and soft, the sloped molded body will be finished with a scissors, and it can be finished neatly without the occurrence of undercut U on the slope, and it can be made into a scissors that does not easily collapse due to water leakage. .

  The present invention is not limited to the first and second embodiments. First, the saddle surface hitting means 30 and its forward / backward movement mechanism S are shown in the above embodiment, but the slope hitting plate 30B is swung around the fulcrum O1 at the lower end. As shown in FIG. 17, an advancing / retracting mechanism S that moves the slope striking plate 30 </ b> B forward / backward by the expansion / contraction movement of the hydraulic cylinder may be adopted, and may be pressed as a whole. Further, as shown in FIG. 18, an advancing / retreating mechanism S that supports the front side of the slope striking plate 30 </ b> B so as to be rotatable and connects the oscillating arm to the rear side to advance / retreat may be adopted. In this case, a configuration provided with the upper surface hitting plate 30A may be provided, or a configuration provided with no top hitting plate 30A may be used. Further, as shown in FIG. 19, an advancing / retreating movement mechanism S that attaches a crank arm to a raising / lowering arm that moves up and down and connects the crank arm to the slope striking plate 30B with an advancing / retreating arm to move forward / backward is adopted. You may do it. Even when such various facet striking means 30 and its forward / backward movement mechanism S are employed, the same operational effects as those of the first and second embodiments can be exhibited.

  Further, although it is the sloped surface molded body 40A, in the figure, the flat plate-like pressing piece 40C made of stainless steel is combined in a truncated pyramid shape with the rear side in the rotation direction protruding toward the slope side of the flange forming part, and the rear side is R. The outer peripheral edge 40I of the pressing piece is formed in a truncated cone shape, but is not necessarily limited thereto, and may be simply a cone shape or a pyramid. A trapezoidal shape may be used, or a resin flat plate-like pressing piece 40C may be combined in a truncated pyramid shape so that the rear side in the rotation direction protrudes to the slope side of the ridge forming portion. Further, although it is the upper surface molded body 40B, the figure shows a resin frustum shape, but it may be simply a cylindrical shape, or a combination of resin plates on the surface of the cylinder in the shape of an impeller. Good. Even when such a configuration is adopted, the same operational effects as those of the first and second embodiments can be exhibited. Further, although the slope tillage blade R3 is shown in the figure, it is composed of a blade inclined according to the slope angle of the slope, but the invention is not necessarily limited thereto, and the blade may reciprocate. The cutter may be rotated. In addition, the basic configuration of the tiller 1 is not particularly limited, and various configurations such as those having different configurations such as a tiller blade, a prime mover, wheels, and a hiddle are conceivable.
