  The present invention relates to a glazing machine, and more particularly, to a glazing machine provided with a pre-processing unit that cuts and fills an old paddle and a trimming unit that applies the piled soil onto the cut old paddle.

  Such a hoe coater is, for example, in the axial direction of the cultivating shaft on the outer peripheral surface of the cultivating shaft supported so as to be rotatable along the advancing direction while proceeding along the heel with the forward movement of a traveling machine body such as a tractor. A configuration in which the pre-treatment unit provided with a plurality of rows of tilling claws protruding at a predetermined distance is used to leap up the soil for culling the old culm, and the laid portion is applied to the old culm by the trimming unit. Is adopted.

  However, with this dredge coater, depending on working conditions such as dredging soil quality and weather, which are different from region to region, the binding between the old dredging and the embankment will be weak and a solid dredging will not be formed. There was a case that could not be done.

  Therefore, a banking mechanism in which a plurality of lifting claws are radially provided on a mounting shaft that is rotatably supported and extends in the traveling direction, and a trimming tool having a substantially conical outer peripheral surface that can trim one side surface of the kite. The seesaw motion is arranged in the intermediate part in the direction of travel between the leveling mechanism, which is composed of a leveling body capable of simultaneously leveling the upper surface of the roll body and the ridge and one upper side of the ridge, and the embankment mechanism and the grading mechanism Thus, there has been proposed a straightening machine provided with a preliminary shaping mechanism for preliminarily shaping one side surface of the basket (see Patent Document 1).

  According to this grading machine, the soil is raised on the old ridge by the embankment mechanism, and the raised soil is preliminarily clamped by the preliminary grading mechanism. Tighten the sides and the base of the heel. Therefore, the upper surface of the heel, one side surface of the heel, and the base of the heel can be securely clamped to form a stronger heel.

A sizing machine equipped with an internal clamping mechanism that is arranged closer to the old ridge and tightens the old ridge by kneading the embankment located inside the new ridge by rotating contact between the outer peripheral surface and the raised protrusion. Has also been proposed (see Patent Document 2).

  According to the grading machine described in Patent Document 2, it is possible to clamp only the surface layer portion, and the inside that is likely to be insufficiently tightened can be tightened to the inside. In addition, a robust bag can be obtained even inside.

JP-A-9-51704 JP-A-10-136708

  Such a conventional straightening machine can clamp the surface and base of the Xinjiang and the inside, but the boundary between the base of the Xinjiang and the farmed field, The surface cannot be clamped. For this reason, the hail collapses from this boundary and water leakage occurs, or water leakage from the tillage track easily occurs.

  The present invention has been made to solve such a problem, and not only the surface layer portion of the Xinjiang but also the inside of the Xinjiang that is difficult to be pressed or the base of the Xinjiang to the rim surface is firmly tightened. An object of the present invention is to provide a wrinkle coater capable of forming a strong wrinkle by pressing and capable of forming a wrinkle that is difficult to leak.

In order to achieve the above-mentioned object, the padding machine of the present invention is mounted on a traveling machine body, disposed at a position offset laterally with respect to the traveling position of the traveling machine body, and pre-processing for crushing an old fence In the scissor coater that performs the scissoring work that proceeds with the traveling of the traveling machine body, the pretreatment part is supported rotatably. A cultivating shaft extending along the traveling direction, a plurality of cultivating claws provided on the cultivating shaft and rotating on the same rotational axis as the cultivating shaft, and a cultivating shaft extending rearward in the axial direction of the cultivating shaft from the plurality of cultivating claws Cultivated trace tightening pressure that clamps the soil piled up on the surface of the old cultivated trace that has been rotated by the same rotation axis as the cultivated axis from the tillage surface Ka1 to the edge surface Ka2. Means (Cultivation trace tightening press in embodiment) Characterized in that it comprises a 30,41,45) and (claim 1).

  The term “extends along the traveling direction” of the present invention includes a case where it extends parallel to the traveling direction of the coater, and a case where it extends obliquely with respect to the traveling direction of the coater.

  The “cultivation claw” of the present invention includes a cultivation claw that cuts and cultivates old culvert and dredged soil, and a cultivating claw that can supply the cultivated soil to the adjustment unit side.

  The “edge surface” of the present invention includes a field surface obtained by cutting the field interior side from the base of the tilling trace by the tilling claws of the pretreatment section.

The “cultivation trace clamping means” of the present invention rotates together with the tillage shaft of the pretreatment unit and clamps the soil piled up on the surface of the tillage trace from the slope of the tillage trace to the ridge surface. Specifically, the tilling mark tightening pressure means is a tightening means for tightening soil with the rotation of the support portion at the tip of the support portion that is attached to the tillage shaft and rotates on the same rotation axis as the tillage shaft. An appendage is provided (claim 2).

  In the present invention, the “clamping portion that performs the soil clamping operation” is to apply the soil piled up on the surface of the tillage to the tillage with a clamping margin. A plate-like contact portion (contact plate portion 32a in the embodiment) extending so that the rear side has a tightening margin with respect to the front side in the rotation direction is provided (claim 4).

  The “contact portion” of the present invention may be either one whose front side in the rotational direction is fixed to the tilling shaft and whose rear side is opened, or one whose front side and rear side in the rotational direction are fixed. The contact portion may be any one that extends linearly, one that curves, or one in which a linear member is bent in a plurality of stages.

  The maximum rotation radius of the rotation locus of the tightening portion of the present invention is smaller than the rotation radius of the tilling claw having the maximum rotation radius among the plurality of tilling claws provided on the tilling shaft. 3).

  In this way, the soil piled up on the surface of the cultivated ruins of the old culvert that has been cut down is securely squeezed by the fastening part, and a layer of soil that is firmly tightened on the surface of the cultivated ruins or on the edge of the ridge is formed. Can be formed.

  Further, the contact portion of the tightening portion of the present invention is provided with an inclination angle with respect to the traveling direction (Claim 5).

  In the present invention, “having an inclination angle with respect to the advancing direction” means that the contact portion of the tightening portion is inclined with respect to the advancing direction, specifically, the contact portion of the tightening portion. A case where the front side in the traveling direction is inclined outward with respect to the rear side and a case where the front side in the traveling direction of the contact portion is inclined inward with respect to the rear side are also included.

  In the pretreatment unit of the present invention, the tilling shaft is provided with an inclination angle with respect to the traveling direction (claim 6).

  In the present invention, “having an inclination angle with respect to the traveling direction” means that the tilling axis of the pretreatment unit is tilted with respect to the traveling direction. The case where it inclines outside with respect to a rear side, and the case where the advancing direction front side of a tilling axis inclines inward with respect to a rear side are also included.

  In this way, the tilling shaft of the pretreatment unit has an inclination angle with respect to the traveling direction, and the contact portion of the tightening unit is provided with an inclination angle with respect to the traveling direction. It is possible to incline the cultivated trace clamping pressure means with respect to the traveling direction. Therefore, as compared with the tilling pressure tightening means that is not inclined with respect to the traveling direction, the rotation contact area of the tilling mark tightening means can be increased. It can be tightened from the tillage surface to the ridge surface with greater force. Moreover, the binding property of the soil clamp | tightened by the pressure difference of a contact part can be improved.

  According to the present invention, the pretreatment unit is supported by the plurality of tilling claws provided on the tilling shaft that is rotatably supported and extends in the traveling direction, and the tilling shaft is located behind the tilling shaft in the axial direction. Cultivation trace pressure means that clamps the soil piled up on the surface of the tillage of the old ridge that is provided on the extending tillage shaft, rotates with the tillage shaft, and is cut by the tillage pawl from the slope of the tillage to the edge surface. By tightening the soil piled up from the slope of the tillage mark to the ridge surface by the tillage pressure tightening means, the soil piled on the tightened soil layer is further tightened by the trimming unit. . For this reason, two layers of clamped soil are formed on the slope of the tillage mark, and a robust new ridge that has been hardened to the inside of the ridge can be formed. Therefore, even if the surface layer of the fresh potato collapses due to water waves or the like during the scraping operation, the inner layer remains, so that water leakage can be prevented. Moreover, since the soil layer clamped from the base of the new ridge to the shore surface is formed by the tilling trace tightening means, water leakage from the shore surface can be prevented.

  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The best mode of a coater according to the present invention will be described below with reference to FIGS. In addition, since there are various types of glazing machines, and the present invention is compatible with these various varnishing machines, a working unit having a pre-processing unit and a trimming unit, which are the main parts of the present invention. A wrinkle coater will be described with reference to a drawing that describes only the above.

  As shown in FIG. 1 (plan view), the wrinkle coater 1 is attached to the rear portion of the traveling machine body 90 and moved to a position offset laterally with respect to the traveling position of the traveling machine body 90. Is provided with a working unit 10 that performs the wrinkling operation.

  The working unit 10 includes a pre-processing unit 11 for embedding the cut soil, and a trimming unit 60 for applying the piled soil on the cut old iron. The working unit 10 is arranged on the moving end side of the offset mechanism unit so that the working direction of the working unit 10 is parallel to the traveling direction A of the traveling machine body 90 regardless of the swinging of the offset mechanism unit provided in the coater 1. Is held rotatably.

  A main shaft extending in the vertical direction is rotatably supported on the moving end side of the offset mechanism portion, and the main shaft is rotated by receiving a driving force from the traveling machine body 90. A power transmission mechanism that connects the main shaft and the preprocessing unit 11 and a power transmission mechanism that connects the main shaft and the rectifying unit 60 are connected to the main shaft. For this reason, the pre-processing unit 11 and the trimming unit 60 are driven to rotate by the driving force transmitted from the traveling machine body 90 via the main shaft and the power transmission mechanism.

  The trimming unit 60 includes a polyhedral drum 62 attached to a rotating shaft 61 supported so as to be rotatable in the left-right direction with respect to the traveling direction, and a cylindrical portion 63 attached to the right end of the polyhedral drum 62 and extending in the left-right direction. And is supported on the moving end side of the offset mechanism portion.

  The pre-processing unit 11 is supported on the moving end side of the offset mechanism unit as shown in FIGS. 1, 2A (as viewed from the arrow Ia in FIG. 1), and FIG. 2B (side view). A tilling shaft 12 serving as a rotation shaft of the pretreatment unit 11 extends substantially parallel to the traveling direction A of the coater 1, is rotatably supported, and is connected to a power transmission mechanism connected to the main shaft. For this reason, when the main shaft rotates, the pretreatment unit 11 rotates through the power transmission mechanism.

  When the tips of the tilling claws 17, the scooping claws 21, and the tightening portion 32, which are described later, are at positions facing the old tack K, the pre-processing section 11 moves from the upper part of the old tack K to the lower side. It rotates in the direction of the moving arrow X, that is, in the down cut direction.

  The pre-processing unit 11 includes the tilling shaft 12 described above, a plurality of tilling claws 17 that are radially attached to the outer periphery of the tilling shaft 12 and rotated together with the tilling shaft 12, and the axis of the tilling shaft 12 rather than the plurality of tilling claws 17. The scooping claw 21 is provided on the rear side in the direction, and the tilling mark clamping device 30 is provided on the rear side in the axial direction of the tilling shaft 12 with respect to the scooping claw 21.

  The tilling claws 17 are arranged in two rows with a predetermined distance from the front side to the rear side of the tilling shaft 12, and each row has a phase difference of 180 degrees in the circumferential direction of the tilling shaft 12. A tilling claw 17 is attached. The tilling claw 17 is detachably attached to a holder 12a projecting from the outer periphery of the tilling shaft 12 through fastening means such as a bolt 12b.

  The tilling claw 17 has a vertical blade portion 17b and a horizontal blade portion 17c continuously extending from an attachment base portion 17a attached to the holder 12a, and bends in a direction opposite to the rotation direction from the vertical blade portion 17b to the horizontal blade portion 17c. The horizontal blade portion 17c is bent to one side with respect to the vertical blade portion 17b to form a rake face 17d on the inner side. In the present embodiment, the horizontal blade portion 17c is curved rearward in the traveling direction. Each of the vertical blade portion 17b and the horizontal blade portion 17c is formed with a blade edge portion 17e having a substantially constant width, and the blade edge portion 17e is a single blade.

  When this tilling claw 17 rotates, it rushes into the soil from the vertical blade portion 17b and cuts the soil in the left-right direction with respect to the traveling direction, and the horizontal blade portion 17c enters into the soil and the soil is predetermined in the front-rear direction. The cultivated soil is held by the rake face 17d of the horizontal blade portion 17c, and after the horizontal blade portion 17c comes out of the soil, the plowed soil is thrown to the old dredge side and inverted. The

  These tilling claws 17 are configured such that the rotation radius Rf of the tilling claws 17 on the front side in the axial direction of the tilling shaft 12 is smaller than the rotation radius Rr of the tilling claws 17 on the rear side in the axial direction (see FIG. 1). . For this reason, the tillage resistance at the time of the padding operation is reliably dispersed, the vibration of the tilling can be made relatively small, and a stable padding operation can be performed. The second row of the tilling claws 17 are arranged with a phase shift of about 90 degrees with respect to the first row of the tilling claws 17. The phase shift is not limited to 90 degrees, and may be smaller than the same phase or 90 degrees.

  A scooping claw 21 is provided on the rear side of these tilling claws 17. The claw claw 21 has a claw body portion 21a continuously extending from a base portion attached to a holder 12a projecting from the tilling shaft 12 on the base end side, and a rotation direction front side edge portion of a tip portion of the claw body portion 21a. It has the scooping plate part 21b attached along this edge. The claw claw 21 is detachably attached to the holder 12a via the bolt 12b in the same manner as the tilling claw 17.

  The claw body portion 21a is bent in the same direction as the rotation direction of the pretreatment portion 11, and a mounting surface portion having a predetermined width is formed on the front side edge portion in the rotation direction on the tip side. The attachment surface portion is bent in the same direction as the rotation direction, and the scooping plate portion 21b is attached to the attachment surface portion in a curved state along the attachment surface portion. For this reason, the claw claw 21 conveys the soil so as to hold the soil, and releases the soil held after the scooping plate portion 21b reaches the upper portion of the rotation area to the old dredge side.

  The scooping plate portion 21b is disposed on the rotation rear side of the working area of the tilling claw 17 (see FIG. 2A). An action area means the rotation area of the vertical blade part 17b and the horizontal blade part 17c at the time of rotation of the tilling claw 17, and in this embodiment, the scooping plate part 21b is on the rotation rear side of the cultivation claw 17 having the action area. It arrange | positions so that it may be applied to a part of action area | region in planar view (refer FIG. 1). For this reason, the scooping plate portion 21b can surely scoop up the soil cultivated by the tilling claws 17 as the padding machine 1 moves forward, and the scooping plate portion 21b vibrates with a foreign object such as a stone. There is almost no risk of damage. In addition, the scooping plate part 21b may be disposed so that the entire area is within the working area in the plan view of the preprocessing part 11.

  Further, the scooping plate portion 21b is disposed at a position where the tip end portion thereof and the tip end portion of the tilling claw 17 approach each other as viewed in the axial direction of the tilling shaft 12 (see FIG. 2A). Further, the scooping plate portion 21b is arranged on the extension line E of the horizontal blade portion 17c of the tilling claw 17 so that the rotation trajectory of the tip portion of the scooping plate portion 21b is inside the rotation trajectory of the tip portion of the tilling claw 17. (See FIG. 2 (a)).

  Thus, the scooping plate portion 21b of the scooping claw 21 is disposed at a position where the tip portion thereof and the tip portion of the tilling claw 17 are close to each other in the axial direction of the tilling shaft 12, and the tip portion of the scooping plate portion 21b. Is arranged on the extension line E of the horizontal blade portion 67b of the tilling claw 17 so that the rotation trajectory is inside the rotation trajectory of the tip portion of the tilling claw 17, so that a relatively large stone or the like in the field When the pretreatment unit 11 is rotated, even if the foreign object hits the tilling claw 17 during rotation of the pretreatment unit 11, it is difficult for the foreign object to hit the scooping claw 21, and damage to the scooping claw 21 is suppressed.

  The tilling shaft clamping device 30 described above is provided on the tilling shaft 12 on the rear side in the axial direction of the tilling shaft 12 with respect to the claw claw 21. The tilling trace clamping device 30 includes a disc-shaped support portion 31 that is coaxially attached to the tilling shaft 12, and a plurality of tightening bolts that are disposed on the peripheral portion of the support portion 31 with a predetermined interval in the circumferential direction. Attached portion 32 is provided.

  The tightening portion 32 is formed of a plate-like member such as a sheet metal, and is bent from the one end portion of the contact plate portion 32a and the contact plate portion 32a disposed along the outer periphery of the support portion 31, and the support portion. And a mounting portion 32b extending to the 31 side. The contact plate portion 32a is curved so that the outside is convex, the front end portion in the rotation direction of the contact plate portion 32a is disposed so as to contact the peripheral edge portion of the support portion 31, and the rear side in the rotation direction of the contact plate portion 32a advances to the rear side. Accordingly, it extends in a direction away from the peripheral edge of the support portion 31. For this reason, a fastening margin S for fastening the accumulated soil is formed between the front end portion and the rear end portion in the rotation direction of the contact plate portion 32a. Although this tightening margin S will be described in detail later, the slope Ka1 and the tillage trace Ka of the tillage trace Ka (see FIG. 3A) of the old tack K cut by the tillage claw 17 of the pretreatment unit 11 This is a tightening width when the contact plate portion 32a tightens the soil piled up on the drooping surface Ka2.

  The attachment portion 32b is formed from the position in front of the rear end in the rotation direction of the contact plate portion 32a to the front end portion in the rotation direction of the contact plate portion 32a. Through holes for passing fastening means such as bolts are provided on both sides of the mounting portion 32b in the rotational direction. The attachment portion 32b is disposed so as to face the front surface of the support portion 31, and is fastened and fixed to the support portion 31 by a bolt 34 inserted through the through hole. When the fastening part 32 is fixed to the support part 31, the surface of the contact plate part 32a becomes substantially parallel to the axial direction of the tilling shaft 12 (see FIG. 1).

  Further, the tightening portion 32 is fixed to the support portion 31, and the position where the maximum rotation radius R1 of the rotation locus of the tightening portion 32 is smaller than the maximum rotation radius R2 of the tilling claw 17 provided on the tilling shaft 12. (See FIG. 1). That is, the tightening portion 32 is arranged at a position where the radius R1 of the rotation locus of the rear end portion in the rotation direction of the contact plate portion 32a is smaller than the maximum rotation radius R2 of the tilling claw 17 provided on the tilling shaft 12. .

  When the hulling operation is performed by the hull coater 1 configured as described above, as shown in FIG. 3A, the tilling claw 17 of the pretreatment unit 11 cuts off the old hail K, and the old hail K is cut off. Cut and cultivate the surface. The soil cut and cultivated by the cultivating claw 17 is piled up on the cultivation trace Ka of the old culvert K that has been crushed by the craving claw 21 disposed on the rear side in the traveling direction of the cultivating claw 17. .

  As shown in FIG. 3 (b), the soil piled up on the tillage trace Ka of the old fence K is dredged from the slope Ka1 of the tillage trace Ka by the contact plate portion 32a of the tightening portion 32 of the tillage trace pressure device 30. It is tightened over the surface Ka2. Accordingly, a soil layer (hereinafter, referred to as “inner layer 35”) fastened to the slope Ka1 of the tillage trace Ka and the ridge surface Ka2 is formed in an arc shape in a side view.

  Further, the soil piled up on the tillage trace Ka of the old fence K is tightened in contact with the slope Ka1 of the tillage trace Ka and the top face of the old fence K, as shown in FIG. 3 (c). Thus, a new ridge N is formed in which a clamped soil layer (hereinafter referred to as an “outer layer 37”) is formed on the slope of the inner layer 35 and the top surface of the old ridge K.

  The Xinjiang N is configured such that an inner layer 35 is formed inside the slope side and an outer layer 37 is laminated on the surface of the inner layer 35. Further, an inner layer 35 is formed on the surface of the heel so that an inner layer 35 formed on the inner side of the slope of the shin N is extended on the surface of the rim of the new heel N. For this reason, two layers of the clamped soil are formed on the slope Ka1 of the tillage mark Ka, and a solid new paddle N solidified to the inside of the paddle is formed.

  FIG. 11A (plan view) shows a working unit 70 including a preprocessing unit 71 having a comparison target structure with the preprocessing unit 11 of the present application. The pretreatment unit 71 is obtained by removing the tilling crushing pressure device 30 from the pretreatment unit 11 described above, and the other structure is the same as that of the pretreatment unit 11. For this reason, the pre-processing unit 71 attaches the same reference numerals to the same aspects as the pre-processing unit 11, and a description thereof is omitted.

  As shown in FIG. 11B, the working unit 70 including the pre-processing unit 71 having the structure to be compared has the tilling claw 17 moved to the old ridge when the pre-processing unit 71 rotates in the downcut direction (arrow X direction). While cutting K, the surface of the old ridge K is cut off. The soil cut by the tilling claw 17 is piled up on the tillage trace Ka of the old hail K that has been scooped up by the claw claw 21 disposed on the rear side in the traveling direction of the tilling claw 17.

  As shown in FIG. 11 (c), the soil piled up on the tillage trace Ka of the old fence K is clamped to the slope Ka1 of the tillage trace Ka and the top face of the old fence K by the trimming unit 60, A new ridge N ′ in which an outer layer 37 is formed on the slope face Ka1 of Ka and the top surface of the old ridge K is completed.

  Thus, the new culm N ′ formed by the pre-processing unit 71 of the structure to be compared is formed on the slope Ka1 of the tillage trace Ka and the top surface of the old culm K, as shown in the left side of FIG. Although the tightened outer layer 37 is formed, the binding property of the outer layer 37 may be weak depending on the field conditions and the like. In this case, the outer layer 37 is displaced from the slope Ka1 of the tillage trace Ka as shown in the left side view of FIG. There is a risk of water leaking from the top of the field.

  In addition, when a hole 80 or a passage 81 made of mole or a mouse exists at the bottom of the new bag N ′, even if the new bag N ′ is formed by the pre-processing unit 71 of the structure to be compared, FIG. As shown in the left side view, the outer layer 37 is not formed at the edge of the new ridge N ′, and therefore cannot block the passage 81 such as a mole. Further, since the bottom surface of the tillage remains cut by the tillage claws, there is a possibility that water in the field may leak to the outside through the passage 81 or from the tillage mark closer to the field than at the bottom.

  On the other hand, according to the pretreatment unit 11 of the present application, the new culm N formed by the pretreatment unit 11 is clamped on the slope Ka1 of the tillage trace Ka as shown in the right side view of FIG. Two soil layers of the inner layer 35 and the outer layer 37 are formed. For this reason, the binding property of the outer layer 37 is weak depending on the field conditions, etc., and even if the outer layer 37 slips down due to water waves or the like at the time of scraping work, as shown in the right view of FIG. The inner layer 35 remains on the slope Ka1 of Ka. Therefore, there is no possibility that the water in the field leaks from the upper part of the new rice cake N.

  Further, even when a hole 80 or a passage 81 made of mole or a mouse exists at the bottom of the old basket K, the pre-processing unit 11 of the present application can be applied to the surface of the paddle from the upper part of the new paddle N and further to the farming side. Since the inner layer 35 clamped over the surface is formed, the inner layer 35 can block the passage 81 such as a mole. For this reason, it is possible to prevent the water in the field from leaking to the outside through the passage 81 or from the tillage mark.

  Note that the preprocessing unit is not limited to the above-described structure, and may be, for example, as shown in FIGS. That is, the pre-processing unit 40 includes a plurality of tilling claws 17 arranged in two rows in the axial direction of the tilling shaft 12 on the tilling shaft 12 and the axial direction of the tilling shaft 12 relative to the second row of tilling claws 17. Tillage provided with a contact plate portion 41b that presses the soil piled up on the tillage trace that is disposed on the rear side and cut by the tillage claw 17, and a scooping plate portion 41c that supplies the soil plowed by the tillage claw 17 to the old rod side. And a trace clamping device 41.

  The tillage crushing pressure device 41 includes a claw body portion 41a continuously extending from an attachment base attached to a holder 12a projecting from the tillage shaft 12, and a contact plate portion attached to the tip of the claw body portion 41a. 41b and a scooping plate portion 41c.

  The nail body 41a is attached to the holder 12a via the bolt 12b in the same manner as the tillage nail 17. The claw body portion 41a is bent in the same direction as the rotation direction of the pretreatment unit 40, and the front end side of the claw body portion 41a is divided into two forks to the front side and the rear side in the rotation direction of the tilling shaft 12, and the rear side extension support portion 41a1 and the rear side extension. The support portion 41a2 is formed.

  A contact plate portion 41b extending along the rotation direction of the pretreatment unit 40 is attached to the front end portions of the front side extension support portion 41a1 and the rear side extension support portion 41a2. The contact plate portion 41b is a plate-like member formed of a metal material such as a sheet metal, and supports the front extension so that the rear side is positioned on the radially outer side of the pretreatment portion 40 with respect to the front side in the rotation direction of the contact plate portion 41b. A fastening margin S is formed between the front end portion and the rear end portion in the rotation direction of the contact plate portion 41b, attached to the portion 41a1 and the rear extension support portion 41a2.

  A scooping plate portion 41c extending along the direction in which the front side extension support portion 41a1 extends is provided on the front end surface in the rotation direction of the front side extension support portion 41a1. The scooping plate portion 41c is inclined so as to extend forward in the rotational direction as it moves outward in the radial direction of the pretreatment portion 40 in a side view. For this reason, the scooping plate part 41c can carry the soil so as to hold the soil, and the soil held after the scooping plate part 41c reaches the upper part of the rotation area can be released to the old paddle side.

  The front end portion in the rotation direction of the scooping plate portion 41c is arranged close to the front end portion in the rotation direction of the contact plate portion 41b described above. For this reason, when the pre-processing part 40 rotates, the contact plate part 41b is prevented from being deformed by contact of the soil with the inner surface on the tip side of the contact plate part 41b.

  A plurality of claw body portions 41 a to which the contact plate portion 41 b and the scooping plate portion 41 c are attached are provided with a predetermined phase difference with respect to the tilling shaft 12. FIG. 6 shows a case where two nail body portions 41a are provided with a phase difference of 180 degrees, and FIG. 7B shows a case where the four nail body portions 41a have a phase difference of 90 degrees. The case where it has and is provided is shown. In addition, the number of the nail | claw main-body parts 41a is not restricted to 2 or 4, One or 3 or more may be sufficient.

  When the pre-processing unit 40 configured in this way rotates in the down cut direction (arrow X direction), as shown in FIG. 8A, the plurality of tilling claws 17 cut the old kite K and the old kite K Cut the edge surface. As shown in FIG. 8B, the soil cut by the tilling claws 17 is scooped up by the scooping plate portion 41c of the tilling mark clamping device 41 disposed on the rear side in the traveling direction of the tilling claws 17. It is piled up on the cultivated trace ka of the old fence K which was cut.

  The soil piled up on the tillage trace Ka of the old fence K is clamped by the contact plate 41b of the tillage trace pressure device 41, and the slope Ka1 of the tillage trace Ka of the old fence K and the edge surface Ka2 of the tillage trace Ka. The tightened inner layer 35 is formed. Further, as shown in FIG. 8C, the soil piled up on the tillage trace Ka of the old fence K is tightened in contact with the slope Ka1 and the top surface of the tillage trace Ka by the trimming unit 60. Accordingly, a new ridge N is formed in which the slope Ka1 of the tillage trace Ka and the outer layer 37 fastened to the top surface are formed.

  As described above, the claw plate claw 21 and the tilling trace clamping pressure shown in FIG. 1 described above are provided by including the scooping plate portion 41c capable of releasing soil on the one claw main body portion 41a and the contact surface portion 41b capable of fastening the soil. Compared with the pretreatment unit 11 in which the device 30 is provided separately on the tilling shaft 12, the number of parts can be reduced and the cost can be reduced, and the pretreatment unit 40 can be made compact.

  The tillage crushing pressure device 45 may be as shown in FIG. 9 (side view). This tilling trace clamping device 45 is provided with the scooping plate part 41c described above on the front side in the rotational direction of the front end part of the claw body part 41a whose front end side is bent forward in the rotational direction, and the rear end of the claw main body part 41a in the rotational direction. A swing restricting plate 46 extending to the side is provided, and a contact plate portion 45 b is provided outside the swing restricting plate 46.

  The scooping plate portion 41c is attached so that the tip side protrudes from the tip of the claw body portion 41a. The distal end portion of the scooping plate portion 41c extends in the vicinity of a position after deformation of the contact plate portion 45b described later.

  The swing restricting plate 46 is bent at the intermediate portion in the rotation direction toward the claw body portion, and the rear side in the rotation direction of the swing restricting plate 46 is a deformation of the contact plate portion 45b that becomes the tightening margin S of the contact plate portion 45b. It extends to the rear side in the rotational direction so as to follow a later position (hereinafter referred to as a deformation position S2).

  The contact plate portion 45b is a plate-like member such as a sheet metal, and the rear side in the rotation direction of the contact plate portion 45b is bent at a plurality of locations, and the mounting base portion 45b1, the arm portion 45b2, the contact pressing portion 45b3, the escape portion from the front end side to the rear side. It has a portion 45b4 and is formed to be convex outward in a side view. The attachment base 45b1 is fastened together with the swing restricting plate 46 via the bolt 12b to the tip of the claw body 41a. The arm portion 45b2 extends away from the outer surface of the swing restricting plate 46 as the arm portion 45b2 moves rearward in the rotational direction.

  The tip of the arm part 45b2 is disposed at a position before deformation of the contact plate part 45b (hereinafter referred to as the original position S1), and the contact pressing part 45b3 connected to the arm part 45b2 extends along the original position S1. The escape portion 45b4 connected to the contact pressing portion 45b3 extends from the outside of the original position S1 to the tilling shaft 12 side beyond the deformation position S2.

  For this reason, when the contact plate portion 45b comes into contact with the soil piled up on the tillage trace of the old ridge, the arm portion 45b2 is elastically deformed and swings toward the swing restricting plate 46, and the arm portion 45b2 moves to the swing restricting plate 46. If it contacts, the movement of the contact press part 45b will be controlled. Therefore, the earth piled up is tightened with the width of the tightening margin S by the contact pressing portion 45b. For this reason, it is possible to form the inner layer 35 fastened to the slope of the old cultivated trace or the surface of the cultivated trace (see FIG. 3C).

  In addition, although the Example mentioned above showed the case where it arrange | positions so that the extending direction of the tilling axis | shaft 12 of the pre-processing part 11 may extend substantially parallel to the advancing direction, as shown to Fig.10 (a), a tilling axis | shaft is shown. It may be arranged with an inclination angle θ that inclines toward the heel side as 12 advances in the traveling direction A. In the present embodiment, the tilling shaft 12 is arranged with an inclination angle θ of an acute angle (about 18 degrees in the drawing).

  Thus, when the tilling shaft 12 is disposed so as to be inclined toward the old ridge in plan view, the cultivating claw 17 cuts obliquely with respect to the old ridge K and moves the soil in that direction. The direction of the flow can be set to the trimming unit 60 side. For this reason, foreign substances such as stones can easily escape and there is little risk of overloading, and the flow of soil supplied to the trimming unit 60 is smooth and stable scouring work can be performed.

  Further, when the tilling shaft 12 is disposed with an inclination angle θ with respect to the traveling direction A, the contact plate portion 32a of the tightening portion 32 is also disposed obliquely with respect to the traveling direction A. Therefore, when the pretreatment unit 11 rotates, the soil piled up on the tillage trace of the old tack K by the claw 21 is inclined and pressed toward the inner side of the tack by the contact plate portion 32a, and the tillage trace The inner layer 35 is tilted and tightened on the slope and the edge surface (see FIG. 10B). At this time, as compared with the non-inclined contact plate portion, the contact area with the soil by rotation becomes large, so that the soil can be tightened with a larger force.

  Furthermore, when the contact plate portion 32a inclined obliquely rotates around the tilling shaft 12, the front side of the contact plate portion 32a has a larger maximum radius of rotation than the rear side, and therefore moves inside the reed. For this reason, even if the tightening margin S is the same, the degree of soil tightening by the front side of the contact plate portion 32a is stronger than that of the rear side of the contact plate portion 32a. For this reason, the binding property of the inner layer 35 itself clamped while having this pressure difference can be further improved, and the binding property with the outer layer 37 clamped on the surface thereof can be further enhanced.

  Therefore, as shown in FIG. 10B, the soil piled up on the tillage trace Ka of the old ridge K is brought into contact with the slope Ka1 of the tillage trace Ka and the top surface of the old ridge K as shown in FIG. It is done. A clamped outer layer 37 is formed on the slope of the inner layer 35 and the top surface of the old ridge K, so that a new ridge N that is stronger and more robust inside the ridge can be formed.
