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. 16, in order to widen the limit that can deal 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.

  The present invention has been made on the basis of the above-mentioned problems. The object of the present invention is to form a high ridge and clean and solidly finish the upper surface of the embankment and the entire slope so that the operation can be performed speedily. A molding machine is provided.

  In order to achieve the above object, a dredger forming machine according to claim 1 of the present invention includes a machine body equipped with a prime mover, a traveling wheel provided in the fuselage and rotated by the prime mover, and a cultivated soil rotated by the prime mover. A tilling blade that is scraped up, a top plate that is provided behind the tilling blade and that tightens the upper surface of the soil, and a slope plate that compacts the slope, and the upper end side is a rocking motion mechanism with the lower end side of the slope plate as a fulcrum The beveling means for rocking by the oscillating means and the rotating shaft provided in the direction perpendicular to the advancing direction of the machine body and arranged on the slope side of the ridge forming portion behind the dripping means and rotated by the prime mover A sloped shaped body formed by combining a driven flat plate-like pressing piece into a truncated pyramid shape with the rear side in the rotation direction protruding toward the slope side of the ridge-forming part and forming the outer peripheral edge of the pressing piece into a truncated cone shape , Formation of the above-mentioned slope molded body Parts thereof distal end side provided on the upper surface side is characterized in that anda top molded body formed in a tubular shape so as to project to the ridge forming the upper surface side.

  A scissor forming machine according to claim 2 is the scissor forming machine according to claim 1, characterized in that the upper surface molded body has a truncated cone shape.

  Moreover, the scissor forming machine according to claim 3 is a scissor forming machine according to any one of claims 1 to 2, wherein the slope of the old scissors of the scissor forming part is scraped off the tip side of the tilling blade on the scissor forming part side. It is characterized by having a surface tillage blade.

  Moreover, the straw molding machine according to claim 4 is the straw molding machine according to any one of claims 1 to 3, wherein the tilling blade scrapes up the tillage to the straw forming part side and the tilling soil to the rut forming part side. The tilling blades that are scraped up are arranged on the left and right.

  That is, in the case of the scissor forming machine according to the present invention, a scissor striking means for flatly striking the top surface and the slope of the scissors, and a sloped surface molded body for flatly striking the scissors and top surfaces of the scissors. Therefore, the top surface and the entire slope are surely finished to a flat surface even with a large uneven surface, and the shape is finished neatly and well. In particular, the sloped molded body is formed by combining the flat pressing pieces in the shape of a truncated pyramid so that the rear side in the rotation direction protrudes toward the slope side of the flange forming portion, and the outer peripheral edge side of the pressing pieces is formed in a truncated cone shape. Since the cultivated soil enters between the ridge forming surface and the truncated pyramid-shaped pressing piece and is pressed by the impeller-shaped pressing piece, and the outer peripheral edge of the pressing piece is formed in a truncated cone shape, Without escaping to the groove side, it is possible to consolidate the accumulated soil from the bottom up. In addition, the intermittent pressing force of the sloped surface molded body on the slope of the ridge is generated a plurality of times during one rotation, so that it is surely compacted. Furthermore, the upper surface molded body formed in a cylindrical shape is rolled and pressed so as to press the upper surface of the ridge. In this way, the forming operation of the ridge can be performed quickly and efficiently.

  According to the scissor forming machine of the present invention, the bottom face and the whole slope of the scissors can be firmly pressed and formed high, and the top surface can also be pressed flat in a horizontal state by the cylindrical top surface molded body. Therefore, even if the surface of the coral is large and uneven, the upper surface can be surely finished to be a flat surface, and the upper surface and the slope can be finished in a solid shape. Further, the wrinkle forming operation can be performed quickly and efficiently.

  The cocoon forming machine 100 of the present invention uses a hand tractor (cultivator) 1 as a towing vehicle 1A. Of course, a passenger tractor described later may be used as a towing vehicle. 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 pair of left and right tilling blades R1, R2 for scraping the soil 20A to 20C and a slope tilling blade R3 for scraping off the slope 20D of the old tack 20 are provided. The front wheel (double wheel) R0 and the pair of right and left tilling blades R1 and R2 allow the tiller 1A to go straight with good left-right balance. That is, the pair of right and left tilling blades R1 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 opposite slope side, the hand tractor (cultivator) 1 The 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. It should be noted that the configuration may be such that the six blades R1 on the slope side face the slope side, the three blades R1 on the slope side face the slope side, and the three blades face the slope side. 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 O <b> 1 at the lower end of the slope plate 30 </ b> B can be rotated by a pin P <b> 1 at the lower end of the frame F <b> 1 suspended from the support cylinder 31 attached to the body F. It is pivotally supported by. The slope plate 30B is provided with an upper surface plate 30A that taps on the upper surface. The upper surface plate 30A is attached to the slope plate 30B in such a manner that the height of the upper surface plate 30A can be adjusted according to the height of the ridges by means of attaching a plurality of holes and bolts. The upper surface plate 30A may be integrally attached to the slope plate 30B. The slope plate 30B and the top plate 30A are connected to a drive system DO (described later in FIG. 7) DO using a prime mover E as a drive source through a swing motion mechanism at the upper corner portion so as to swing the plate. . 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 to swing the slope plate 30B, and the lower end of the connecting rod L4 is connected to the support shaft P4 on the upper portion of the slope plate 30B. ing. Thus, the connecting rod L4 moves back and forth in the direction of the axis of the arrow (c), thereby swinging the slope plate 30B in the direction of the arrow (2). With such a configuration, the upper surface plate 30A and the slope plate 30B are swung in the left-right direction perpendicular to the flange 20 indicated by the arrow (2) at a predetermined rotational speed with the lower end fulcrum O1 as the center. 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, a large-diameter pyramidal surface body 40A is mounted in an impeller shape on the outer peripheral portion 63A of the first cylindrical portion 63 fitted to the rotary shaft 50. 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 °.

  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 ridge forming part. In addition, since the outer peripheral edge 40I of the pressing piece is formed in a truncated cone shape, the cultivated soil enters between the straw molding surface and the truncated pyramid-shaped pressing piece and is pressed by the impeller-shaped pressing piece. Since the outer peripheral edge side of the piece is formed in a truncated cone shape, the soil does not escape to the groove side, and the accumulated soil can be pressed up sequentially from the bottom. 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.

  Next, referring to FIG. 7, a driving 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. explain. 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.

  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, 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.

  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. 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, the surface of the old slope face 20D is scraped off by the tilling blade R3. 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. 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.

  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. 17, 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. 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 °. 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. Further, since the outer peripheral edge 40I of each pressing piece 40C in the sloped surface molded body 40A is formed in a truncated cone shape, the bottom face portion 20E of the slope face of the ridge 20 is firmly pressed without any gap, so that the bottom face portion of the slope face 20D. 20E soil 20A is less likely 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.

  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, 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 a plurality of times during this one rotation. Can occur, and can be compacted securely and can form a slope that does not collapse easily.

  Furthermore, 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.

  Next, a wrinkle forming machine 300 according to a second embodiment of the present invention will be described with reference to FIG. In the case of the present embodiment, the tow vehicle 1A is replaced by a riding tractor 80 instead of the walking type traveling device. In this embodiment, a rotating disk 40 ′ having the same type as that of the ridge-shaped body 40 is attached to the opposite side. Then, an upper surface plate provided behind the tilling blade for compacting the upper surface of the soil and a slope plate for compacting the slope are integrally formed, and the upper end side is swung by the swing motion mechanism with the lower end side of the slope plate as a fulcrum. The beating surface hitting means 30 is attached to a rotating shaft provided in a direction perpendicular to the advancing direction of the machine body, and is rotationally driven by the prime mover. A sloped shaped body 40A formed by combining a flat pressing piece in a truncated pyramid shape with the rear side in the rotation direction projecting to the sloped side of the flange forming part, and forming the outer peripheral edge of the pressing piece in a truncated cone shape, An upper surface molded body 40B ′ formed in a cylindrical shape is provided on the upper surface side of the ridge forming portion of the sloped molded body so that the tip side protrudes toward the upper surface side of the ridge forming portion. Other configurations are the same as those in the first embodiment, and the description thereof will be omitted. According to such a riding tractor 80, the body of the tractor 80 can be balanced in a stable posture even if the tilling blade R1 is not symmetrical.

  Next, a third embodiment of the present invention will be described with reference to FIGS. Although the above embodiment has been described with reference to an example of a paddle forming machine for forming paddy paddles, it is applied to paddle forming instead. That is, in the apparatus of the first embodiment, the rotating shaft 50 and the drive shaft 33 are extended to the left side in the drawing, and the ridge forming body 40 and the ridge surface hitting means 30 are also provided on the opposite side (left side in the drawing) of the machine body. It is a thing. 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.
