Description

  The present invention provides a finisher having a trimming body for shaping the collar, and continuously finishing the surface from the top surface to the slope on the top surface trimming section for shaping the top surface of the collar among the trimming bodies. The present invention relates to a trimming blade having a function, and a trimming body using the same.

  The brush coater has a frusto-conical sloped surface adjuster and a cylindrical upper surface adjuster connected to its tip in the axial direction. The old dredged soil that has been loosened by the treatment body is reshaped as a dredging having a slope and an upper surface. The trimming body is given a rotational speed that allows it to roll at a speed faster than the traveling speed of the paddy coater, and exerts the function of compacting the surface soil by rolling on the slope and top surface of the paddle by slip rotation ( Patent Document 1).

  As the trimming body rotates by slip, the slope trimming section and the top trimming section apply pressure to both the slope and the top of the collar, so that the tightened collar can be shaped. The soil tries to slide to the slope side by the pressure acting from the upper surface, and the reaction force at that time can be received by the slope trimming unit. A compaction effect can be obtained (see Patent Document 2).

  However, in Patent Documents 1 and 2, dynamic pressure is applied to the soil by striking the top surface of the saddle using a drop or a step when the trimming body rotates, so that the surface soil may be disturbed or scattered. There is.

  On the other hand, by bending a plurality of blades as in Patent Document 1 connected to the outer periphery of the upper surface trimming part and making one blade in contact with the upper surface in two stages, There is a method of increasing the pressure effect on the soil by the blade plate compared to the case where the blade plate having a cylindrical surface is brought into contact with the upper surface of the ridge (see Patent Document 3).

JP-A-2000-37106 (Claim 1, paragraphs 0013 and 0019, FIGS. 3, 4, and 7 to 9) Japanese Patent Laying-Open No. 2006-55121 (Claim 1, paragraphs 0021 to 0022, FIGS. 2 and 3) Japanese Patent No. 3997473 (Claim 1, paragraphs 0008, 0012 to 0014, FIGS. 3 and 6)

  According to the method in which the bent blade plate is brought into contact with the upper surface of the ridge as in Patent Document 3, the direction of the blade plate surface is different with the convex portion facing the axial direction of the upper surface adjusting portion being sandwiched. The area of contact with the upper surface of the heel during rotation around the axis is smaller than when using a continuous flat surface having no part or a blade having a curved surface. As a result, it is said that there is an advantage that the pressure applied to the soil increases when it comes into contact with the upper surface of the ridge and the pressurizing effect is enhanced (paragraph 0012).

  In Patent Document 3, blades that overlap each other in the circumferential direction and are formed with ridges in the radial direction are also connected to the slope (side) trimming section, but from the top trimming section to the slope trimming section. Since both slats are discontinuous at the transition boundary, any one of the slats of the upper surface grading section and the slats of the slope grading section does not straddle the ridge upper surface and the slope surface simultaneously. Therefore, the upper surface and the slope of the heel cannot be pressed simultaneously by any of the blade plates, and it is difficult to finish the boundary portion between the heel face and the slope (side surface) in a continuous surface in the width direction of the heel.

  In particular, the blades of the top surface adjustment section are positioned on the heel side from the slope surface adjustment section, so when they are in contact with the heel surface, they tend to be pressed from the slope surface adjustment section to the heel surface side. Since the ridges are formed over the entire length in the axial direction on the blades of the part, it cannot be curved so as to form a curved surface when pressed from the slope trimming part.

  If the blades of the upper surface adjustment section are pressed by the slope adjustment section and forced to bend toward the heel side, the angle of the ridges will be within the range from the upper surface adjustment section to the slope adjustment section. As a result of spreading and the absence of the ridges, the edge on the downstream side in the circumferential direction of the slats faces the heel side when contacting the surface (upper surface and slope) of the heel. For this reason, with the rolling of the upper surface trimming part, when the edge is about to be separated from the heel surface, the heel surface may be kicked, leaving a linear trace facing the width direction on the heel surface. Further, since the blade is assumed to be bent at an unspecified position in the axial direction, the bent portion may press the upper surface of the ridge, and as a result, a planar trace may be left on the surface of the ridge.

  From the above background, the present invention proposes a blade plate of an upper surface adjusting portion that makes it possible to continuously finish the surface from the upper surface to the slope, and an adjusting body having an upper surface adjusting portion using the same. To do.

A blade for a trimming body of a glaze coater according to a first aspect of the present invention is connected to a slope trimming portion for shaping the slope of a kite by rotation around an axis, a support member serving as a main body, and a peripheral surface thereof. A plurality of blades, and is connected to the tip end portion in the axial direction of the slope trimming portion and rotates together with the slope trimming portion, and includes an upper face trimming portion for shaping the upper surface of the collar. A blade that constitutes the upper surface trimming part of the trimming body mounted on the coating machine,
A connecting portion connected to the support member; and a projecting portion that is continuous with the connecting portion and projects to the downstream side in the rotation direction of the upper surface trimming portion, and at least the slope trimming of the projecting portion. The end portion on the portion side is shaped so as to approach the slope adjusting portion side from the top face adjusting portion side from the upstream side to the downstream side in the rotation direction of the top face adjusting portion, and the slope adjusting portion. It is assumed that a transition portion that overlaps with is formed.

  The “support member serving as the main body” refers to a support member that constitutes the main body of the upper surface trimming unit. The support member itself is formed in a columnar shape, a polygonal column shape, a truncated cone shape, a truncated pyramid shape, or the like, and it does not matter whether the peripheral surface (surface) of the support member is closed or open. When the support member is composed of a plate having no opening, the peripheral surface is closed, and when the support member is composed of a frame member, the support member is open.

  The “upstream side in the rotation direction” refers to the front side in the direction of rotation when the upper surface trimming part rotates about the axis (the side that comes in contact with the front surface of the collar). “The transition part has a shape that approaches the slope adjusting part side from the upper surface adjusting part side from the upstream side to the downstream side in the rotational direction” means that the upper surface adjusting part extends from the upstream side to the downstream side in the rotational direction. The transition part is formed in, for example, a triangular shape or a trapezoidal shape from this shape, and at least a part on the side of the slope adjusting part is a part of the slope adjusting part. It overlaps the surface from the heel side. When the slope trimming part is composed of a plurality of blades, the transition part overlaps the blades. The length of the transition portion in the axial direction may gradually increase (increase gradually) from the upstream side to the downstream side in the rotational direction, or may increase in stages.

  The phrase “overlap with the slope trimming portion” means that the transition portion may directly overlap (contact) the surface of the slope trimming portion or may overlap with a gap. The transition part overlaps with the surface of the slope adjusting part with a gap between the transition part or the blade plate in a state where the part from the projecting part to the transition part is curved as described above. Realized by being manufactured. In this case, the blades of the upper surface adjustment unit are pressed to the heel side from the blades of the slope adjustment unit when the adjustment body rotates, and thus overlap the surface of the slope adjustment unit (blade plate). Touch the surface or line. Therefore, in a state where the trimming body is not rotating, it is not always necessary that the blade plate of the upper surface trimming unit is in contact with the blade plate of the slope trimming unit.

  “At least the transition portion is formed at the end of the overhang portion on the slope trimming portion side” means that the transition portion is formed in the range of the overhang portion and the connection portion to the overhang portion. Say that it may be formed. As described above, since the transition portion has a shape that approaches the slope trimming portion side from the upstream side to the downstream side in the rotation direction, the ratio of the transition portion to the range of the overhang portion is large as a whole.

  When the slope trimming part is composed of a plurality of blades, the blades are rotated in order to increase the pressing force applied to the upper surface along with the rotation, like the upper surface trimming part. Since the blades located on the upstream side in the direction are combined so as to cover the upstream end of the blades located on the downstream side, in the part where the two blades are adjacent in the circumferential direction, the blade located on the upstream side The plate overlaps the surface side of the vane plate located on the downstream side. In other words, the surface of the blade plate located on the upstream side is located on the upper surface side of the blade plate located on the downstream side, and between the surface of the blade plate on the upstream side and the surface of the blade plate on the downstream side. There is a step. In this relationship, in order to avoid interference with the blade located upstream of the slope trimming portion, the transition portion of the blade blade of the top trimming portion extends from the range of the overhanging portion to the slope trimming portion side. It is reasonable to be formed to overhang.

  As shown in FIG. 1 and the like, when the transition part of one slat constituting the upper surface sizing part straddles, for example, two slats constituting the slope sizing part, the transition part is the slope sizing. It overlaps with the downstream blade from the upstream blade. As described above, since there is a step between the two blades of the slope adjusting part, the edge (end) on the slope adjusting part side of the transition part is the blade on the upstream side of the slope adjusting part. If the shape is such that it draws a curve that connects (passes) a point on the surface and a point on the downstream vane surface, the edge (end) on the slope adjustment side of the transition part It will be in the state which contacts the surface of the two blades of a collar part simultaneously. While the edge (end) of the upper surface adjustment part on the side of the slope adjustment part is in contact with the surface of the slope adjustment part, the axial length of the transition part gradually increases from the upstream side to the downstream side. In some cases, the transition portion has a triangular shape, and the transition portion becomes trapezoidal when the axial length of the transition portion becomes constant from the middle.

  If the transition part is not there, for example, it is additionally connected to a rectangular slat or it is continuous in an integrated form, straddling the slope adjustment part from the upper surface adjustment part, On the other hand, it contacts continuously from the upper surface to the slope. The transition part can continuously finish the surface smoothly from the top surface to the slope by contacting the surface from the top surface to the slope, where the shaping state tends to be discontinuous. Become.

  In particular, the transition section is a range from the tip of the upper surface adjustment section in the axial direction to the slope adjustment section by contact with the surface of the slope adjustment section when the adjustment body rotates. Since the curved surface is curved so that the axial side of the upper surface trimming part is convex and the heel side is concave (FIGS. 1, 6 to 8A), the blades of the upper surface trimming part are shaped. The plate has a curved surface in the range from the top surface to the slope (FIG. 8- (b)). The overhanging portion, which is a portion excluding the connecting portion and the transition portion connected to the support member of the upper surface trimming portion, forms a curved surface having a concave side with respect to the axis of the upper surface trimming portion. The part from the part to the transition part forms a curved surface whose convex side is convex with respect to the plane facing the circumferential direction of the upper surface trimming part (FIGS. 6 to 11).

  In the case of a slat without a transition part, the upper surface and the slope are independently shaped to shape the upper surface and the slope, respectively, so that the finished upper surface and the slope are flat. Therefore, the boundary part becomes a polygonal column shape, and a corner appears in the boundary part. The corners protruding at the boundary between the upper surface and the slope are susceptible to external forces during farming, and are liable to collapse due to the load from the upper surface or the impact force on the corners. On the other hand, in the present invention, the transition portion of the upper surface trimming portion straddles the slope trimming portion, and the boundary portion between the upper surface of the corrugation and the slope is finished to be a curved surface, so that the protrusion of the corner portion is eliminated, so that stability against collapse is eliminated. There is an advantage that the characteristics are remarkably improved.

  In addition, since the transition portion overlaps the surface of the slope trimming portion, the transition portion blocks the gap at the boundary portion between the separated top surface trimming portion and the slope trimming portion from the surface side. It functions to suppress the intrusion of earth and sand into the inside of the support member, which is the main body of the upper surface trimming section, or the connecting portion between the upper surface trimming section and the slope trimming section.

  The transition portion is also a part of the upper surface adjusting portion, so that it approaches the upper surface with rotation of the upper surface adjusting portion and tries to overlap the peripheral surface of the support member when contacting, In addition to overlapping with the blades of the trimming section, it functions to allow the soil on the upper surface of the trough to flow toward the slope trimming section. In addition, the soil at the boundary between the upper surface and the slope is leveled together with the blades of the slope trimming unit or as part of the blades of the slope trimming unit, and functions to consolidate to the inner side of the cage. As a result, since the soil at the boundary between the upper surface and the slope surface is continuously and evenly pressed, a situation of discontinuity is avoided.

  In Patent Document 3, the end of the blade plate of the upper surface adjustment portion on the side of the slope adjustment portion is shaped so as to approach from the upper surface adjustment portion side to the slope adjustment portion side from the upstream side to the downstream side. It looks like, but the blades of the upper surface adjustment part do not overlap the surface of the slope adjustment part, so the blades of the upper surface adjustment part are continuous in the range from the upper surface of the hook to the slope It is difficult to form a curved surface. Even if a part of the blade plate end of the upper surface trimming unit may come into contact with the surface of the slope trimming unit, only a part of it, for example downstream If only one part of the blade is in contact and the other part is not in contact, excessive pressure is concentrated on the part from the slope trimming part. is there.

  On the other hand, the transition portion of the present invention, as described above, is rotated from the midway position in the axial direction of the upper surface adjustment portion to the slope adjustment portion by contact with the surface of the slope adjustment portion when the adjustment body rotates. In the range, along the surface of the slope trimming part, it curves so that the axis side of the top trimming part becomes convex and the collar side becomes concave (FIGS. 9 and 11). From this, since it is possible to contact the slope trimming part in the entire length of the edge on the slope trimming part side in the transition part, there is no action of excessive pressure on a part of the edge of the transition part, Factors that accelerate damage are eliminated.

  As described above, it is sufficient that the blades of the upper surface adjusting portion are in contact with the surface of the slope adjusting portion by a surface or by a line as long as the adjusting body is rotating, and at least by the line. As a result, the reaction force received from the slope trimming part by the transition part coming into contact with the slope trimming part is dispersed, so that concentration of pressure on the edge is avoided and the possibility of damage is also reduced. ing.

  The overhanging portion that protrudes downstream in the rotational direction from the connecting portion connected to the support member follows the surface shape of the support member, and as a whole is a curved surface (curved surface) that is convex on the surface side (concave on the support member side) or bent Although the surface is formed, the transition portion comes into contact with the surface of the slope trimming portion and tends to bend or bend in the opposite direction to the overhanging portion, that is, on the side opposite to the support member. In this relation, if the bending rigidity of the boundary portion between the transition portion and the overhanging portion is not an extent that does not hinder the bending at the boundary portion, an unspecified position in the blade plate axial direction may be bent as in Patent Document 3. There is.

  When there is a possibility that the slats bend at the boundary position with the overhang due to its material properties, wall thickness, etc., for example, when the blade contacts the surface of the slope rectifying part, By giving elasticity that can be bent to the surface side (Claim 2), the bending rigidity at the boundary portion between the transition portion and the overhang portion can be relaxed. Here, “surface” refers to the surface of the vane itself, and refers to the opposite side of the shaft (support member) of the upper surface adjusting portion. As a result, it is possible to avoid the occurrence of a situation where bending at an unspecified position is avoided and the bent portion presses the upper surface of the heel and leaves a trace on the heel surface. If a material with low bending rigidity, such as a thin steel plate or other metal plate or a synthetic resin plate, is used for the blade plate itself, the blade plate itself has elasticity that can be bent to the surface side.

  In order to bend the transition portion when contacting the surface of the slope trimming portion, it is not always necessary to give the transition portion elasticity that can be curved. It is also possible to curve the range from the overhanging portion to the transition portion by giving the transition portion a curved surface that assumes the situation where it contacts the surface (FIGS. 9 and 11).

  “Elasticity that can be bent to the surface side” means that the blade surface is elastically deformed to the opposite side of the support member in accordance with the surface shape by contact with the surface adjustment portion of the blade, and the surface adjustment portion is in the deformed state. The state where it is in close contact with the surface of the slope trimming part by the restoring force to restore to the side. In the range where the blades of the upper surface adjusting portion overlap with the support member as described above, the support member side forms a concave curved surface, but if the overhanging portion and the transition portion are viewed in the circumferential direction of the blade plate, the blade plate moves from the overhanging portion. The range to the part is a curved surface convex toward the support member.

  Giving the transition portion “elasticity that can be bent toward the surface side” specifically means that at least the end of the slope adjustment portion in the axial direction of the upper face adjustment portion is at the end of the slope adjustment portion. This is made possible by giving a length that allows contact with the surface. The fact that the transition portion has elasticity that can be curved toward the surface side includes a case where the transition portion is curved by contact with the slope-grading portion during rotation and a case where the transition portion is pre-curved during molding of the blade.

  As described above, the transition part may or may not come into contact with the surface of the slope trimming part when the trimming body is not rotating, but the transition part can contact the surface of the slope trimming part. The bending rigidity of the entire slat including the transition part is reduced by giving a long length and increasing the axial length of the slat, and it can be easily bent and deformed by contact with the sloped surface. Therefore, the occurrence of a discontinuous bent portion as in the case of forced bending deformation is avoided.

  Since the plurality of blades constituting the upper surface trimming unit are connected to the surface of the support member at intervals in the circumferential direction while covering the surface of the support member as a whole (Claim 7), The overhanging portion projects from the connecting portion connected to the surface of the support member to the downstream side in the rotational direction in the tangential direction of the circumferential surface, and when the upper surface adjusting portion is viewed in the axial direction, the plurality of blades are arranged in a bowl shape . For this reason, with the rotation of the upper surface trimming part, when the slats are going to be detached from the cocoon upper surface, it is assumed that the slats have elasticity, so that the soil on the cocoon upper surface is spun up by the restoring force, It is possible to suppress or prevent the soil from jumping up by forming a return portion that is curved or bent toward the support member at the tip end in the circumferential direction of the overhanging portion of the slats (Claim 4).

  Since the distal end portion in the circumferential direction of the overhang portion is an end portion on the downstream side in the rotation direction of the upper surface trimming portion, and the overhang portion can form a concave curved surface toward the support member side, The term “bend” means that the circumferential tip is bent or bent with a larger curvature than the other protruding portion, and the circumferential tip is directed toward the support member by forming the return portion (see FIG. 9, FIG. 10).

  For example, if the tip of the overhanging portion of the slat has the same curvature as the other parts (the overhanging portion of the blade is a uniform curved surface or a flat surface up to the tip), the tip is detached from the top surface In this case, it is conceivable that the soil on the top surface of the reed is repelled toward the reed side by the reaction force when rapidly restoring from the elastic deformation state.

  On the other hand, since the return portion curved toward the support member is formed at the distal end portion in the circumferential direction of the overhang portion, it is in contact with the upper surface until the tip portion is detached as shown by the chain line in FIG. Can be maintained. In particular, the surface on the heel surface side of the return portion forms a convex curved surface, so that the surface on the heel side of the return portion remains in contact with the heel surface when detached from the heel surface accompanying rotation of the upper surface adjusting portion. Alternatively, it is possible to level without flipping the soil because it tries to float from the top surface of the kite while sliding on the top surface of the kite.

  As described above, the blades of the upper surface adjustment portion overlap the surface of the slope surface adjustment portion at the transition portion, and work to finish the surface smoothly and continuously from the upper surface to the slope surface. When in contact with the surface trimming part, it is desirable that the transition part or the part from the transition part to the overhanging part bend uniformly along the surface of the slope trimming part. Therefore, it is appropriate that the return portion formed at the circumferential tip of the overhang portion is formed in a form that does not hinder the elastic deformation of the transition portion into the curved state. On the other hand, when the return part is formed at the circumferential tip of the overhang, the bending rigidity around the axis of the tip is increased, so the blades are bent and deformed around the circumferential axis. It becomes difficult to let you.

  Therefore, by gradually reducing the degree of curvature or bending of the return portion at the circumferential tip of the overhang from the tip end side in the axial direction of the upper surface trimming portion toward the slope trimming portion side (Claim 5). Furthermore, by forming the return portion at the tip end in the circumferential direction of the overhang portion from the overhang portion to the vicinity of the transition portion (claim 6), while maintaining the soil leveling effect at the overhang tip portion, The transition portion can be naturally bent and deformed along the surface of the slope trimming portion. “Axial tip side” refers to the end on the side not connected to the slope trimming portion of both ends in the axial direction of the upper surface trimming portion.

  The degree of curvature of the return part or the degree of bending refers to the curvature of the return part or the surface of the overhang part (the surface on the side in contact with the heel) and the surface of the return part (the surface on the side in contact with the heel). The angle formed is "smaller" means that the curvature or angle gradually decreases and approaches 0 as shown in FIG. 9 and FIG.

  Since the degree of curvature or the like of the return portion gradually decreases from the tip end side in the axial direction of the upper surface adjusting portion to the slope adjusting portion side, the blade in the range from the transition portion or the middle of the overhang portion to the transition portion Since the plate no longer obstructs the bending deformation, the transition portion or the range from the overhanging portion to the transition portion is easily bent and deformed along the curved surface of the surface due to contact with the surface of the sloped surface adjusting portion. If the curvature of the return part approaches 0 at the midway position from the overhang part to the transition part, there is no influence on the bending deformation due to the curvature of the return part, and the blade can be bent and deformed in that range. “Near the transition part” refers to a section from the middle of the overhang part to the middle of the transition part when the blade is viewed in the axial direction.

  As described above, the plurality of blades of the upper surface trimming unit cover the surface of the support member as a whole, and are connected to the surface of the support member at intervals in the circumferential direction to constitute the upper surface trimming unit. To do. That the plurality of blades cover the support member as a whole means that the blades are always in contact with the upper surface when the upper surface adjusting portion rotates. Say to cover. In the case where the support member is, for example, a polygonal column, the blades are disposed between the support member and the heel surface both when the side surface portion of the support member faces the heel surface and when the ridge line portion faces the heel surface. Says to be in an intervening state.

  Specifically, the connecting portion connected to overlap one of the side surfaces of the support member in the case of the polygonal column shape, and the side surface continuous to the connecting portion and adjacent to the downstream side in the rotational direction of the upper surface adjusting portion A plurality of blades as a whole as a result of covering the connecting portions of the blades located on the downstream side in the rotation direction of the upper surface adjusting portion. It will be a shape that covers. The downstream side in the rotational direction is the rear side in the direction of rotation when the upper surface adjusting portion rotates about the axis, and the blades on the downstream side in the rotational direction are relatively upstream of the rotational direction on the upper surface. It contacts after the blade located on the front side. As described above, the support member does not need to have a polygonal column shape, but in the case of a polygonal column shape, there is a good compatibility that facilitates stable connection of the connecting portions of the blades to the support member.

  When the support member has a polygonal column shape, the ridgeline part of the polygonal columnar support member presses the top surface of the support so that one of the blade plates is in contact with the top surface of the support member. When this is done, and when the side surface portion presses the upper surface of the heel, the upper surface of the heel is directly pressed via the blade.

  The state in which the plurality of blades cover the support member as a whole may be obtained when the upper surface adjusting portion rotates and at least one blade is in contact with the upper surface. If a curved surface that is convex toward the outer peripheral side of the member is formed, it is easy to obtain a state in which the blade plate covers the support member during rotation of the upper surface trimming portion. In the case where the blade is composed of a connecting portion and an overhanging portion, the overhanging portion only needs to form a curved surface that protrudes toward the outer peripheral side of the support member.

  When the slats of the slats extend over the same plane as the connecting part, the entire surface of the slats easily touches the top surface of the slats almost simultaneously during the rotation of the top surface trimming part. Since the time in contact with the soil becomes longer, the flat surface may drag the soil on the upper surface of the fence. On the other hand, since the projecting portion forms a curved surface that protrudes toward the outer periphery of the support member, each blade has a shape close to a portion of the cylindrical surface, and a portion of the blade is in contact with the soil. Since the time is shortened, the slats can level the same part continuously by a curved surface by slip rotation without dragging the soil.

  When the upper surface trimming part is composed of, for example, a polygonal column-shaped support member and an elastic blade plate that is connected to the side surface of the support member, the blade plate that directly contacts the upper surface of the support member has the shape of the support member. The upper surface of the heel is pressed while following the deformation. On the other hand, since the support member rotates while keeping the center position on the cross section constant, the distance from the center to the ridge line of the polygonal column and the distance to the side surface are different, so the side surface part is pressed when the ridge line part is pressed. There is a difference in the pressure when the pressure is applied, and the pressure increases when the pressure is applied from the ridge line portion.

  Therefore, the upper surface trimming section has different pressures when pressing the upper surface from the blades positioned on the outer peripheral side of the ridge line portion of the support member and when pressing the upper surface from the blades positioned on the outer peripheral side of the side surface portion. In order to press the upper surface, it is possible to press the same point with two different pressures from the blades by slip rotation by being combined with a polygonal column-shaped support member.

  The ability to pressurize the same point with two different pressures has the effect of compacting the top surface of the reed and the effect of finishing the reed evenly in the length direction, regardless of soil quality or soil moisture content. It is possible to finish the surface soil uniformly while properly compacting the surface soil. If the water content is high, excess water is naturally removed from the soil by consolidation.

  Here, when the ridge line part (corner part) of the polygonal column-shaped support member is in direct contact with the heel face, the pressure applied from the ridge line part to the heel face is greater than the pressure from the side face part, so the blades are leveled. It acts to extrude the soil to both sides of the ridge line portion, and it is assumed that grooves are formed as traces of the ridge line portion on the upper surface of the ridge. This can also be said for the protruding portion of Patent Document 3 that forms a polygonal surface.

  On the other hand, in claim 7, when combined with a polygonal column-shaped support member, a plurality of blade plates cover the surface of the support member as a whole, so that the blades are pressed when pressing the upper surface from the ridge line portion of the support member. Since the plate functions to disperse the pressure, it is possible to press the upper surface of the ridge from the ridge line portion, disperse the pressure while compacting, and even out the soil.

  In particular, when the support member that is the main body of the upper surface trimming unit is a polygonal polyhedron, the support member itself has high rigidity in the radial direction and the circumferential direction, and has high torsional rigidity. Since it has the property of not easily deforming against pressure, the support member itself has high stability against reaction force. For this reason, a sufficient reaction force can be applied from the blades when pressing the upper surface of the flange, and the support member itself is not easily deformed, so that the pressure effect from the blades is reliably exhibited, and the pressure as expected is maintained. It is possible to give.

  The bending rigidity and torsional rigidity required for the support member are ensured by setting the plate thickness of the plate (plate) constituting it to a certain level or more. However, the plate that closes the end surface of the support member or the inscribed plate By adding, the rigidity is remarkably improved.

  Furthermore, in the case of a polygonal column, since the support member is a polyhedron, a sufficient contact area with the support member can be secured when the blade plate is joined to the support member using a bolt or the like. The stability against deformation is improved and the durability against damage is increased.

  In particular, when the overhanging portion of the slat has a length in the circumferential direction that exceeds the side surface of the support member to which the slat plate is connected and the downstream side surface in the rotational direction, the ridge line portion of the support member Since the two slats overlap each other, when the slats level the top surface of the heel, the pressure on the top surface of the slats by the slats can be dispersed more than when one slat is located at the ridge line portion of the support member. This is possible, and the effect of finishing the heel surface smoothly is improved.

  For example, when the ridge line portion of the polygonal column-shaped support member directly contacts the ridge surface, the pressure from the ridge line portion acts on the ridge surface intensively, but two blades overlap the ridge line portion of the support member. As a result, the effect of dispersing the pressure applied from the ridge line portion to the upper surface of the heel increases. In addition, since the slats are elastic (bendable and deformable), when two slats overlap, the curvature of the surface of the top surface adjustment portion that directly contacts the top surface of the slats is one. Since the surface becomes smaller and the curved surface becomes gentler, the leveling effect on the upper surface of the ridge is improved, and a smoother finish is possible.

  In addition, the plurality of blades are in a state of covering the surface of the support member as a whole, or the overhanging portion of the blades is in a state of covering the surface of the blades located on the downstream side in the rotation direction of the upper surface adjusting unit. Thus, since the downstream portion of the blade plate located on the upstream side covers (covers) the joint portion of the blade plate located on the downstream side, soil enters the joint portion of the blade plate, and the joint portion. The possibility of accelerating the damage is reduced and the damage is suppressed.

  The blades are fixed to the outer periphery of the support member when the upper surface trimming unit is in use, but if they are detachably connected to the support member, in addition to cleaning the upper surface trimming unit, It will be possible to replace worn blades. Specifically, an engaging portion protrudes from one of the blade plate and the support member, and an engaged portion that can be engaged with the engaging portion is formed on the other, and the engaging portion and the engaged portion are By engaging each other, the blades are detachably connected to the side surface of the support member.

  The engaging portion is formed on one of the surface on the support member side of the blade plate and the surface on the blade plate side of the support member, and the engaged portion is formed on the surface on the side facing the engaging portion. When the engaging portion and the engaged portion are engaged with each other, it is only necessary to have a relationship capable of maintaining the state where the blade plate is connected to the support member. For example, when the engaging portion is engaged with the engaged portion, The engaging portion may be engaged with the engaged portion in the direction of detachment of the blade plate, that is, in the axial direction or radial direction of the support member. The engaging portion may be formed on a joining member for pressing the blade plate against the support member, which will be described later. In this case, the engagement portion penetrates the blade plate and protrudes toward the support member, thereby making the blade plate Will be projected. In this case, the engaging portion engages with the engaged portion formed on the support member.

  Since the connection of the blade plate to the support member is performed by the engagement of the engaging portion and the engaged portion, the connection work and the separation work of the blade plate to the support member are simplified, and the The efficiency of blade replacement work is improved.

  When the engaging part only engages with the engaged part and the blade cannot secure stability in the joined state to the support member, the blade is engaged with the engaged part at the engaging part. In this state, the stability in the joined state to the support member is improved by joining directly or indirectly to the support member with a bolt or the like at any part of the blade. When the above-described joining member is used for joining the blade plate to the support member, the blade plate is indirectly joined to the support member with a bolt or the like.

  When the engaging portion is engaged with the engaged portion, the blade plate may be separated from the support member in the direction of disengagement. If the joining member is bolted to the support member while being pressed from the outer peripheral side to the support member side by a joining member such as a plate, the disengagement of the engagement is reliably prevented. The joining member abuts on the side surface of the support member or abuts on the side surface and the end surface, and is detachably joined to the support member by screwing a bolt into the side surface or the end surface.

  It has a connection part connected to a support member which is a main body of the upper surface trimming part, and a projecting part projecting from the connection part to the downstream side in the rotation direction, and at least the end part on the slope trimming part side of the projecting part In addition, the transition portion is arranged in the range from the upstream side to the downstream side in the rotational direction to approach the slope surface adjustment portion side from the upper surface adjustment portion side and form a transition portion that overlaps the slope surface adjustment portion. When the body rotates, the slats can be curved so that the heel side is concave due to contact with the surface of the slope trimming part. As a result, the range from the top surface of the ridge to the slope can be finished into a curved surface, and the corner portion does not protrude from the range from the top surface of the heel to the slope, so stability against collapse is improved.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.

  1 (a) to 1 (d) show a truncated cone-shaped slope rectifying section 2 for shaping the slope of the ridge 70 shown in FIGS. 4 and 5 by rotation around an axis, and a support member 31 serving as a main body. And a plurality of blades 32 connected to the peripheral surface thereof, connected to the tip end portion in the axial direction of the slope rectifying portion 2 and rotated together with the slope rectifying portion 2, An example of the configuration of the trimming body 1 that is provided with the top trimming unit 3 that shapes the (skin upper surface) 70 a and is attached to the jar coating machine 10 is shown.

  The slats 32 constituting the upper surface trimming section 3 are connected to the support member 31, and the overhanging section 32 b is continuous to the connection section 32 a and projects to the downstream side in the rotation direction of the upper surface trimming section 3. At least at the end of the projecting portion 32b on the side of the slope trimming portion 2 from the side of the top surface trimming portion 3 from the upstream side to the downstream side in the rotational direction of the top surface trimming portion 3. The transition part 32d which has a shape approaching to the part 2 side and overlaps the slope adjusting part 2 is formed. The vane plate 32 is divided into three regions, that is, a connection portion 32a, an overhang portion 32b, and a transition portion 32d. Details of the blade 32 will be described later.

  As shown in FIG. 13, the brush coater 10 basically coats the parallel connection frames 11, 11 and the parallel connection frames 11, 11 connected to the rear part of the tractor via a three-point link hitch mechanism. A hitch frame 12 connected in the width direction of the machine 10 and an offset frame 13 connected to the rear of the hitch frame 12 so as to be swingable around a vertical axis.

  A connecting member 14 projects in the width direction of the spreader 10 from the front end position of the offset frame 13 in the forward direction, and a link frame 15 is parallel to the offset frame 13 between the connecting member 14 and the hitch frame 12. It is constructed and connected to both sides in a freely rotatable manner. The offset frame 13 forms a parallel link by the link frame 15, the hitch frame 12, and the connecting member 14. The offset frame 13 is stretched between the hitch frame 12 and the tip position of the offset frame 13, and expands and contracts the cylinder 16 connected to both. By this, the hitch frame 12 can be freely offset.

  A gear box 17 connected to the PTO shaft of the tractor via a universal joint or the like is fixed to the tractor side of the hitch frame 12, and power from the PTO shaft is transmitted to the input shaft of the gear box 17. It is transmitted to the driven shaft 18 supported by the tip of the offset frame 13 through the inside of the offset frame 13 through the drive shaft in 17.

  As shown in FIG. 14, the work machine 50 of the wrinkle coater 10 is mainly coaxial with the driven shaft 18 at the tip of the offset frame 13 and is connected to a drive box 51 having a transmission shaft 55 to which power is transmitted from the driven shaft 18. The trimming body 1 is composed of a pretreatment body 52 that projects from the drive box 51 forward in the direction of travel relative to the trimming body 1 and loosens the earth and sand of the old paddle before shaping the trimming body 1. The pre-treatment body 52 has a claw claw 52a that rotates by receiving power from the drive box 51. While the work machine 50 is traveling, the claw claw 52a cuts the earth and sand of the old claw at a position in front of the trimming body 1. It is prepared for shaping by the trimming body 1 by loosening.

  As shown in FIG. 13, an arm 53 projecting toward the trimming body 1 is connected to a connecting portion of the connecting member 14 with the link frame 15, and the work machine 50 is connected between the arm 53 and the drive box 51. Is mounted on the working machine cylinder 54 that swings with respect to the wrinkle coater 10 and is connected to both. The work machine 50 controls the work posture by the expansion and contraction of the work machine cylinder 54.

  A rotation shaft to which power is transmitted from the transmission shaft 55 is disposed in the drive box 41, and the slope adjusting portion 2 of the adjustment body 1 is connected to the rotation shaft. The slope trimming unit 2 is rotated by the rotation of the rotary shaft, and at the same time, the upper surface trimming unit 3 is rotated.

  For example, as shown in FIG. 2, the slope trimming unit 2 is formed in a truncated cone shape as a whole by connecting a plurality of fan-shaped blades 21 at a straight line portion in the radial direction. The connecting portion 22 is connected to the upper surface trimming portion 3 and serves as a positioning reference when connecting the plurality of blades 21 to the portion. The connecting portion 22 is in a state of protruding from the slope trimming portion 2 to the upper surface trimming portion 3 side.

  In the drawings, as shown in FIGS. 4 and 5, as the slope trimming unit 2 rotates, a force that presses the slope (hereinafter, slope face) 70 b of the heel 70 from the upstream side to the downstream side in the rotational direction is applied. In order to increase gradually, the end of the blade 21 located on the relatively upstream side of the blade 21 on the downstream side is overlapped with the blade 21 located on the downstream side from the upper surface trimming unit 3 side. Although the blade 21 is combined, it is not always necessary. The cross-sectional shape of the collar 70 is shown in FIG. There is a case where no step is formed between the adjacent blades 21 and 21 when the adjacent blades 21 and 21 overlap or when they do not overlap. When a step is formed between the adjacent blades 21 and 21, it is related (influenced) to the shape of the transition portion 32 d as described later.

  In the case of illustration, the adjacent slats 21, 21 are supported by being overlapped with the holding part 22b formed on the slat 21 side of the connecting part 22, and a step is formed between the slats 21, 21. They are joined together by welding or the like. In this case, by forming a step between the blades 21, 21, the distance between the surface of each blade 21 and the slope 70b gradually decreases from the upstream side to the downstream side. The force with which the surface of the wing plate 21 on the heel side presses the slope surface 70b gradually increases from the upstream side to the downstream side due to the rotation of the slope surface adjusting portion 2, and has an effect of compacting the slope surface 70b.

  A screw hole 22a is formed on the end surface of the connecting portion 22 on the upper surface adjusting portion 3 side for connection with the upper surface adjusting portion 3 by a bolt 7 or the like. The upper surface adjusting portion 3 is shown in FIG. As shown in FIG. 4, the bolt 7 penetrating in the axial direction is screwed into the screw hole 22a to be connected to the connecting portion 22. The bolt 7 does not need to penetrate the entire length of the upper surface trimming portion 3, and an insertion hole through which the bolt 7 is simply inserted is formed from the end surface on the front end side of the upper surface trimming portion 3, and closer to the slope surface trimming portion 2 ahead The length of the bolt 7 can be shortened by forming a screw hole into which the bolt 7 is screwed.

  When the bolt 7 is used to connect the upper surface trimming part 3 to the connection part 22, there is an advantage that the upper surface trimming part 3 can be connected in a replaceable manner. However, the upper surface trimming part 3 and the connection part 22 are advantageous. In addition to this, by forming a male screw on the outer peripheral surface of one of the upper surface adjusting portion 3 and the connecting portion 22 and forming a female screw on the other inner peripheral surface, the upper surface adjusting portion 3 is It can be rotated around an axis and directly connected to the connecting portion 22 in a replaceable manner.

  1- (a) to (d), as described above, are configured by connecting the slope trimming unit 2 and the upper surface trimming unit 3, and an example of the configuration of the trimming body 1 attached to the corrugating machine 10 is shown. FIG. 4 shows the end face of the top surface adjusting portion 3 on the front end side in the axial direction. The upper surface trimming section 3 includes a support member 31 coupled to the coupling section 22 of the slope trimming section 2 and a plurality of blade plates 32 connected at intervals in the circumferential direction (rotation direction) of the support member 31. Composed. 1 (a) and 1 (b), the alternate long and short dash line indicates the rotation center of the top surface adjustment unit 3, that is, the adjustment body 1, and the arrows around it indicate the direction of rotation.

  As shown in FIG. 4, the main body 31a of the support member 31 constituting the main body of the upper surface trimming section 3 is basically formed by bending one or a plurality of plates or assembling a plurality of plates. These are welded together to form a polygonal column shape, a cylindrical shape, a truncated pyramid shape, a truncated cone shape, or the like. In addition, the main body portion 31a of the support member 31 may be formed by a frame structure in which a frame material is arranged at a portion corresponding to a polygonal column, a ridgeline of a polygonal frustum, or a column or a truncated cone. In these cases, a face material may be disposed on the portion corresponding to the bottom surface at both ends in the axial direction, or in the case of a truncated pyramid, a frame material may be disposed on the portion corresponding to each side of the bottom surface. is there.

  A stiffening plate 31b for joining the blade plate 32 and an end portion on both sides in the axial direction of the main body portion 31a, or an intermediate portion between the end portion and an axially intermediate portion to compensate for insufficient rigidity due to the hollow main body portion 31a. It arrange | positions and is joined to the main-body part 31a. In the drawing, as shown in FIG. 3 (a), a stiffening plate 31b is arranged at the intermediate portion near the end surface of the top surface trimming portion 3 in the axial direction and near the slope surface trimming portion 2, and the stiffener plate 31b is disposed on the end surface. The rigid plate 31b is used to fix the blade plate 32.

  The stiffening plate 31b is joined to the main body 31a by means such as welding or bolt joining while being inscribed in the main body 31a or in contact with the end surface of the main body 31a. The side surface portion of the main body 31a made of a plate is preferably a blind plate in order to ensure rigidity, but an opening may be formed in a part of the side surface portion for the purpose of reducing the weight.

  The stiffening plate 31b is formed with an insertion hole 31c through which the bolt 7 for connecting the upper surface adjusting portion 3 to the connecting portion 22 of the slope adjusting portion 2 is inserted. The stiffening plate 31b is also provided with a screw hole 31d for bringing the blade plate 32 into contact with the stiffening plate 31b using the joining member 4 and joining the stiffening plate 31b with the bolt 5 penetrating the joining member 4 in this state. Is formed. In FIG. 4, the screw hole 31 d is formed as an arc-shaped long hole with respect to the center on the cross section, so that the position of the bolt 7 to the screw hole 22 a of the connecting portion 22 can be adjusted.

  FIG. 4 shows a case where the cross section of the support member 31 of the top surface trimming section 3 is a regular octagon, but the cross sectional shape of the support member 31 is not necessarily a regular polygon. If the cross section of the support member 31 is polygonal, the ridge surface 70a can be pressed by the ridge line portion and the side surface portion of the support member 31 (polygon), and therefore the width of each side surface is different as shown in FIG. It may be a polygon. However, if the support member 31 is a regular polygon, the upper surface 70a can be pressed from the ridge line portion and the side surface portion at a constant time interval when the upper surface trimming portion 3 rotates.

  The slat 32 is elastically deformed along the outer shape of the support member 31 when coming into contact with the collar upper surface 70a, and is synthesized with polypropylene, polyethylene, polyvinyl chloride or the like having elasticity that restores to its original shape as it is detached from the collar upper surface 70a. It is formed from a metal material such as a resin or a steel plate, and is detachably joined to the side surface portion of the support member 31. In some cases, the slats 32 are preliminarily connected to the outer periphery of the support member 31 and are molded so as to form a curved surface convex toward the surface side along the outer peripheral surface of the support member 31. The amount of elastic deformation when contacting the upper surface 70a is small.

  In the drawing, in order to ensure the stability of the blade 32 connected to the support member 31 (to prevent the blade 32 from being detached from the support member 31), the joining member 4 described above is disposed on the outer peripheral side of the blade 32. The blade 32 is detachably connected to the support member 31 by bonding the bonding member 4 to the support member 31. In the drawing, the stiffening plate joined to the end surface of the support member 31 while being connected to the support member 31 in a state where the blade 32 is pressed against the side surface of the support member 31 (main body portion 31a). The function to join to 31b is given.

  In the drawing, in order to simplify the detachable connection work between the blade plate 32 and the support member 31, an engaging portion that engages with the other is formed on one side, and the engaging portion engages with the other side. An engaged portion is formed. As described above, since the joining member 4 is used in the drawing to supplement the connection of the blade 32 to the support member 31, the engaging portion 43 is formed on the joining member 4 and the support member 31 is engaged. Although the portion 33 is formed, the engagement portion 43 of the joining member 4 penetrates the blade plate 32 and protrudes toward the support member 31, so that it is equivalent to the engagement portion 43 protruding from the blade plate 32. become.

  When the engaging portion 43 is formed in the joining member 4, the joining member 4 is joined to the contact portion 41 that overlaps the surface of the blade plate 32 and the end surface of the support member 31 as shown in FIG. The engagement portion 42 is composed of two portions of the joining portion 42 that overlaps the stiffening plate 31b, and is engaged with one of the surface on the blade plate 32 side of the contact portion 41 and the side surface of the support member 31 (main body portion 31a). A joint 43 is projected. FIG. 3B is an enlarged view of the engaging portion 43 portion of FIG. Here, as described above, the engaging portion 43 is formed on the contact portion 41 of the joining member 4 and the engaged portion 33 is formed on the side surface of the support member 31.

  With the formation of the engaging portion 43 in the joining member 4, the engaged portion 33 with which the engaging portion 43 engages is formed on the side surface of the support member 31 (main body portion 31 a). When the engaging portion is formed on the support member 31, the engaged portion is formed on the blade plate 32 or the joining member 4. Further, along with the formation of the engaging portion 43 in the joining member 4, an insertion hole 32f through which the engaging portion 43 is inserted is formed in the connecting portion 32a of the blade 32 as shown in FIG. The engaging portion 43 may protrude from the surface of the blade plate 32 on the support member 31 side. In this case, the contact portion 41 of the joining member 4 simply holds the blade plate 32 against the support member 31. It works to attach.

  The engaging portion 43 has a pin shape having a head portion 43b on the distal end side (supporting member 31 side) of the shaft portion 43a, and the engaged portion 33 is an insertion hole through which the head portion 43b of the engaging portion 43 can be inserted. 33a and the insertion hole 33a, the shaft part 43a of the engaging part 43 has an opening-like shape having a slot 33b in the form of a long hole that can move (slide). As the engaging portion 43, a pin, a bolt, or the like having a head portion 43b is used.

  When the joining member 4 is attached to the support member 31 (main body portion 31 a), the head portion 43 b of the engaging portion 43 passes through the insertion hole 32 f formed in the blade plate 32 and the insertion hole 33 a of the engaged portion 33. Is inserted through the shaft portion 43a. In this state, the shaft portion 43a moves (slides) along the groove 33b of the engaged portion 33, so that the head portion 43b is engaged with the groove 33b on one side in the axial direction and on the radially outer side. The joining member 4 is connected to the support member 31. When the joining member 4 is detached, the shaft portion 43a is moved (slid) along the groove 33b and removed from the support member 31 by pulling the head portion 43b out of the insertion hole 33a.

  The joining portion 42 of the joining member 4 is formed with an insertion hole 42a through which the bolt 5 for joining the joining member 4 to the stiffening plate 31b is inserted. The joining member 4 passes through the insertion hole 42a of the joining portion 42, It is joined to the stiffening plate 31b by a bolt 5 screwed into the stiffening plate 31b.

  With the contact portion 41 of the joining member 4 pressing the blade plate 32 against the side surface of the support member 31, the joint portion 42 is joined to the stiffening plate 31 b of the support member 31, so that the blade plate 32 is supported by the support member 31. The upper surface trimming portion 3 is formed integrally with 331. As shown in FIG. 3A, the upper surface adjusting portion 3 in which the blade 32 is integrated with the support member 31 is bolted to the core member 6 directly connected to the connecting portion 22 of the slope adjusting portion 2 described above. 7 is integrated with the slope trimming unit 2.

  The core member 6 is formed by joining a plurality of flanges 62 having insertion holes, which are disposed on the inner peripheral side of a cylindrical main body 61 at intervals in the axial direction, and for ensuring rigidity. Depending on the soil conditions, the core material 6 can be used as the upper surface trimming section 3. The upper surface trimming portion 3 passes through the stiffening plate 31b joined to the end surface of the support member 31 and the flange 62 of the core member 6, and into the screw hole 22a formed in the connecting portion 22 of the sloped surface trimming portion 2. The reaching bolt 7 is screwed into the screw hole 22a to be joined to the core member 6. FIG. 3- (c) shows an end face on the stiffening plate 313b side of the upper surface trimming section 3 shown in FIG. 3- (a). 1- (a) to (d) show the external appearance of the trimming body 1 in which the top trimming section 3 is integrated with the slope trimming section 2. FIG.

  As shown in FIG. 4, the vane plate 32 of the upper surface trimming section 3 is connected to a connection portion 32 a that is connected to overlap any one of the side surfaces of the support member 31, and is adjacent to the downstream side in the rotation direction of the support member 31. The overhanging portion 32b extends to the side surface (blade plate 32) side, and the overhanging portion 32b covers the connection portion 32a of the vane plate 32 positioned on the downstream side in the rotation direction of the upper surface trimming portion 3 in the width direction. Have

  Specifically, the projecting portion 32b of the blade 32 has a length in the circumferential direction that exceeds the side surface adjacent to the downstream side in the rotational direction from the side surface of the support member 31 to which the blade plate 32 is connected. . That is, the downstream end portion of the overhanging portion 32b of the blade plate 32 has a length that extends beyond the ridge line portion of the side surface adjacent to that side, and further extends to the adjacent side surface. As shown in FIG. 5, in a state where the two blade plates 32 are overlapped, the slip rotation is performed while the soil on the ridge upper surface 70 a existing forward in the traveling direction is wound under the blade plate 32.

  FIG. 5 shows a state where the upper surface trimming portion 3 having the support member 31 that is not a regular polygon is rolling on the upper surface 70a. When the blade 32 presses the collar upper surface 70a because the downstream end of the projecting portion 32b of the blade 32 has a length exceeding the ridge line portion of the side surface adjacent to that side, a plurality of drawings Then, the two blade plates 32 are overlapped, and the pressure from the support member 31 is transmitted to the upper surface 70a through the plurality of blade plates 32.

  The blade 32 is overlapped on the side surface of the support member 31 by the above-described joining member 4 at the connection portion 32a and joined to the support member 31 in a state of being pressed to the center side on the cross section. The connection part 32a is in a state of being constrained to the support member 31 by the joining member 4 by being joined in a state where the connection part 32a overlaps with a side surface forming a plane of the support member 31. In this state, the overhang portion 32 b forms a curved surface such as a cylindrical surface that protrudes toward the outer peripheral side of the support member 31, and is in a state where it can be bent (elastically) deformed with respect to the support member 31.

  By forming a curved surface in which the overhanging portion 32b is convex toward the outer peripheral side of the support member 31, when the overhanging portion 32b comes into contact with the upper surface 70a, the distance from the center of the support member 31 to the ridge line is defined as a radius. It becomes a shape close to a cylinder having a circular arc surface.

  As described above, the overhanging portion 32b has a length exceeding the side surface adjacent to the downstream side in the rotational direction in the circumferential direction, and is curved convexly toward the outer circumferential side of the support member 31, whereby the upper surface trimming portion 3 is curved. During rolling, the two blades 32 overlap and begin to wind the soil under the blades 32, and the soil is smoothed on the curved surface until the tip 32c is separated from the saddle upper surface 70a on the downstream side in the rotational direction of the blades 32. Will be. At this time, since the upper surface trimming portion 3 rotates by slip, the upper surface 70a is consolidated and the surface is finished smooth.

  When the upper surface trimming portion 3 rolls, the center position on the cross section of the upper surface trimming portion 3 is kept constant, so that the ridge line portion of the support member 31 approaches the collar upper surface 70a and tries to press, A difference occurs in the pressing force from the blade 32 when the side surface portion approaches and the pressure is about to be pressed, and the pressure when the ridgeline portion is about to be pressed increases.

  In this relationship, when pressing the heel surface 70a from the ridge line portion of the support member 31 through the blade plate 32, the soil is pressed with a larger pressure, and when pressing from the side surface portion through the blade plate 32, the pressure is smaller than that. Therefore, the upper surface trimming unit 3 can consolidate the upper surface 70a with two different pressures. Further, since the upper surface trimming section 3 rolls (slips) on the upper surface 70a at a speed higher than the moving speed, the surface is uniformly leveled while pressing the upper surface 70a downward.

  In the drawing, a return portion 32e is formed at the boundary portion between the tip portion 32c in the circumferential direction of the overhang portion 32b of the blade plate 32, that is, the tip portion 32c on the downstream side in the rotation direction and the other overhang portion 32b. By bending or bending 32e toward the support member 31 with a larger curvature than the overhanging portion 32b, the circumferential tip end 32c of the overhanging portion 32b is detached from the collar upper surface 70a as shown in FIG. The tip 32c is prevented from jumping up the soil.

  Since the overhanging portion 32b is forcibly bent and deformed immediately before being detached from the collar upper surface 70a, for example, when the overhanging portion 32b has a uniform curvature in the circumferential direction, the overhanging portion 32b tends to be detached. Sometimes, it is assumed that the distal end portion 32c jumps rapidly from the heel surface 70a by the restoring force. On the other hand, the tip 32c of the overhang 32b is curved with a larger curvature than the other parts due to the formation of the return portion 32e, so that the tip 32c is in contact with the collar upper surface 70a or slips on the collar upper surface. However, it will not leap up because it tries to rise from the top of the fence.

  As shown in FIG. 1, at the end of the projecting portion 32b of the blade 32 on the slope surface adjusting portion 2 side, the upper surface adjusting portion 3 side from the upstream side to the downstream side in the rotational direction of the upper surface adjusting portion 3 A transition portion 32d having a shape approaching from the slope to the slope adjusting portion 2 side is formed. The transition portion 32d is formed mainly from the end position of the overhang portion 32b, but may be formed over the connection portion 32a and the overhang portion 32b.

  The plurality of blade plates 21 constituting the slope adjusting section 2 are combined with the blade plate 21 positioned on the downstream side in the rotation direction overlapping the rear surface of the blade plate 21 positioned on the upstream side, so The blade 21 located on the side is located closer to the upper surface trimming unit 3. In this relationship, in order to avoid a collision with the blade plate 21 located on the relatively upstream side of the slope trimming part 2, the transition part 32d extends from the upstream side in the rotational direction of the upper surface trimming part 3 to the downstream side. Thus, the length of the upper surface trimming portion 3 in the axial direction is increased, and as shown in FIGS. 1- (a) to (d), it is formed in a triangular shape, a trapezoidal shape, a wing shape, or a shape close thereto.

  1 (a), (b), and (d) indicate the boundary position between the overhanging portion 32b and the transition portion 32d of the vane plate 32. The transition portion 32d continues to the overhanging portion 32b, and In the case of being integrally formed as a part of the protruding portion 32b, the broken line does not actually appear. The transition portion 32d is also formed by connecting a separate component from the overhang portion 32b to the overhang portion 32b. As shown in the figure, the transition part 32d overlaps the vane plate 21 of the slope trimming part 2 from the top trimming part 3 side, that is, the collar 70 side, and prevents, for example, turning in the case of a triangular shape or a trapezoidal shape. Therefore, the corner portion is dropped, and the outline of the transition portion 32d is curved.

  When the overhanging portion 32b of the blade 32 comes into contact with the collar upper surface 70a as the upper surface trimming section 3 rotates, and is pushed by the collar upper surface 70a and overlaps the peripheral surface (side surface portion and ridge line portion) of the support member 31. Since the transition portion 32d is also pushed by the heel surface 70a, the transition portion 32d tends to overlap the surface of the blade plate 21 of the slope rectifying portion 2. As a result, as shown in FIG. 8A, since the range from the overhanging portion 32b to the transition portion 32d tends to be curved following the surface of the blade plate 21, the curved overhanging portion 32b is changed to the transition portion. The range extending to 32d presses the slope surface 70b and the collar upper surface 70a toward the inner side of the collar 70, and the portion from the slope surface 70b to the collar upper surface 70a is shaped into a curved surface as shown in FIG. Is done.

  At this time, since the soil on the ridge upper surface 70a is flowed to the slope leveling unit 2 side, the soil at the boundary between the ridge upper surface 70a and the slope is leveled with equal pressure and consolidated to the inner side of the ridge 70. It will be. Since the soil at the boundary between the ridge upper surface 70a and the slope is leveled, the boundary (surface) between the upper surface 70a of the ridge 70 and the slope does not become discontinuous. FIG. 8- (a) shows the blade plate 31 in which the range from the overhanging portion 32b to the transition portion 32d is curved in advance, similar to the blade plate 31 of the upper surface trimming portion 3 shown in FIGS. However, even when it is bent by elastic deformation, it is bent into the same shape as in FIG. 8- (a), and the collar 70 shown in FIG. 8- (b) is shaped.

  6 shows a state in which the trimming body 1 shown in FIG. 1- (a) is viewed from a position near the center of the upper surface trimming section 3, and FIG. 7 shows the upper surface trimming section 3 and the slope trimming section 2 in FIG. The state where the boundary part is enlarged is shown. As shown here, the vane plate 32 of the top surface trimming unit 3 is in a state of straddling the two vane plates 21 and 21 of the slope trimming unit 2 and overlaps the vane plate 21 at the transition unit 32d. The edge (end part) on the slope surface adjusting part 2 side is in contact with the surface of the upstream blade plate 21 and the surface of the downstream blade plate 21 or is in a state where it can contact.

  The state in which the edge of the transition portion 32d can contact the surface of the blade plate 21 is a state in which the transition portion 32d is formed in a curved shape along the surface of the slope rectifying portion 2, and the blade plate 32 is molded. Obtained in case. The transition part 32d may be elastically deformed into a curved surface shape by contact with the slope adjusting part 2, and in that case, the blade plate 32 does not necessarily have to be molded in a state of forming a curved surface, and is formed into a flat plate shape. It only has to be molded.

  The blade 32 is in contact with the surface of the slope rectifying section 2 by at least the transition part 32d being sandwiched between the heel 70 and the slope rectifying section 2 when the rectifying body 1 is rotated (during use). What is necessary is just to form the curved surface from which the range from the overhang | projection part 32c to the transition part 32d is concave to the collar 70 side at that time. FIG. 8- (a) shows a state where the range from the overhang portion 32c to the transition portion 32d presses the collar 70. FIG.

  As shown here, the transition part 32d of the vane plate 32 forms a curved surface having a concave side on the side of the collar 70 due to contact with the slope trimming part 2 as the trimming body 1 rotates. As shown, the range (shoulder portion) from the upper surface 70a to the slope 70b of the ridge 70 is a curved surface. This curved surface is continuous in the length direction of the collar 70 when a plurality of blades 32 arranged in the circumferential direction of the upper surface trimming section 3 presses the collar 70 continuously.

  FIG. 9 and FIG. 11 show the state of the front surface (the surface on the side of the flange 70) and the back surface (the surface on the side of the support member 31) of one blade plate 32, respectively. Here, a flat connecting portion 32a having a length equivalent to the length in the axial direction of the support member 31, a protruding portion 32b that protrudes in the circumferential direction from the connecting portion 32a and curves toward the supporting member 31, and an extending portion. A vane plate 32 manufactured by injection molding or the like from polyethylene or the like is shown in a form having a transition portion 32d protruding from the connection portion 32a and the overhanging portion 32b to the slope adjusting portion 2 side. The transition part 32d forms a curved surface in which the upper surface trimming part 3 side is convex (the ridge 70 side is concave).

  In FIG. 9, the broken line in the circumferential direction of the support member 31 on the side of the transition part 32d shows the boundary between the transition part 32d and other parts for convenience, but here the transition part 32d is connected to the connection part 32a. It forms in the slope adjusting part 2 side over the range to the overhang | projection part 32b. Since the circumferential width of the connecting portion 32a only needs to be large enough to overlap and connect to the surface of the support member 31, it is smaller than the width of the overhanging portion 32b, but from the range of the width of the connecting portion 32a. By forming the transition part 32d, the contact area with the slope trimming part 2 is increased, and the reaction force received from the slope trimming part 2 at the time of deformation is dispersed, so that the transition part 32d is easily bent. Have advantages.

  In particular, in FIG. 9, the edge of the transition portion 32d on the slope trimming portion 2 side in the section from the connection portion 32a to the midway in the circumferential direction of the overhang portion 32b is formed in a straight line on the plane, and the periphery of the overhang portion 32b By forming the edge of the section from the halfway in the direction to the tip 32c into a curved shape along the surface shape (curved surface) of the blade 21 of the slope adjusting part 2, the edge of the transition part 32d extends over the entire length. The surface of the blade plate 21 of the surface trimming unit 2 can be contacted.

  In the example of FIG. 9, a return portion 32e that is curved or bent toward the support member 31 is formed at the distal end portion on the downstream side in the rotation direction of the overhang portion 32b. (Curvature or angle) gradually decreases from the tip end side in the axial direction of the upper surface adjusting portion 3 to the slope adjusting portion 2 side, and is formed from the overhanging portion 32b to the vicinity of the transition portion 32d. 9A to 10C are cross-sectional views taken along lines CC, BB, and AA in FIG. 9, and the curvature or angle of the return portion 32 e is the axis of the top surface adjusting portion 3. Larger near the tip of the direction, smaller near the slope adjusting part 2, and in the range of the transition part 32d, the transition part 32d can be bent to the opposite side of the support member 31 in that range, and the size is almost close to zero. It has become.

  In the range of the transition portion 32d, the curvature or angle of the return portion 32e is close to 0, and in that range, the presence of the return portion 32d inhibits the bending deformation in the range from the overhang portion 32b to the transition portion 32d. Therefore, when the vane plate 32 is elastically deformed by contact with the sloped surface adjusting portion 2, the elastic deformation can be generated without resistance at the deformed portion.

  12- (a) to (e) show a state where the upper surface trimming section 3 shown in FIG. 1 rolls on the upper surface 70a and makes one rotation. The upper surface trimming section 3 rotates while maintaining a constant height from the upper surface 70a to the center of the cross section. As shown in FIGS. 1 and 5, the center position on the cross section of the upper surface trimming section 3 is set to such a height that the two blades 32 are sandwiched between the ridge line portion of the support member 31 and the collar upper surface 70a. Is done.

At this time, the side surface portion of the support member 31 is in a state of floating from the collar upper surface 70a, and the blade plate fixed to the upstream side surface of the connection portion 32a of the blade plate 32 fixed to the side surface portion. The 32 overhanging portions 32b overlap and press the heel surface 70a with an appropriate pressure.

  Since there is a gap between the side surface portion of the support member 31 and the collar upper surface 70a, the overhanging portion 32b of the blade 32 positioned on the outer peripheral side with respect to the support member 31 is convex to the outer peripheral side between the collar upper surface 70a. The soil is pressed while elastically deforming into a curved surface. In this situation, the tip 32c of the blade 32 where the overhang 32b is located on the outer peripheral side of the side portion of the support member 31 facing the upper surface 70a is in contact with the overhang 32b of the downstream blade 32. Yes. At this time, the distal end portion 32c is curved or the like, so that the distal end comes into contact with the protruding portion 32b of the downstream blade plate 32, and the blade plate 32 itself having the distal end portion 32c is separated from the downstream blade plate 32. In order to project, the projecting portion 32b of the blade 32 having the tip portion 32c contributes to elastic deformation into a curved surface convex toward the outer periphery such as an arc surface.

  FIG. 12- (b) shows the situation where the top surface trimming section 3 is rotated by 10 ° from (a). At this time, the ridge line portion of the support member 31 starts to press the collar upper surface 70a, the ridge line portion is pressed by the ridge line portion, and the overhanging portion 32b of the upstream blade plate 32 is crushed through the downstream blade plate 32, The upper surface 70a is pressed with a pressure larger than the situation (a). In this situation, the tip 32c of the blade 32 located on the upstream side of the blade 32 in contact with the flange upper surface 70a in the overhanging portion 32b is about to be detached from the flange upper surface 70a.

Shows the closest situation. At this time, since the ridge line portion of the support member 31 is closest to the heel surface 70a, the heel surface 70a is pressed with the greatest pressure following (b). In the process of shifting from (b) to (c), the tip 32c of the blade 32 on the upstream side of the blade 32 that is in contact with the flange upper surface 70a is detached from the flange upper surface 70a. The distal end portion 32c in the circumferential direction of the overhang portion 32b is detached while sliding on the collar upper surface 70a.

  In FIG. 12- (d), the upper surface trimming portion 3 further rotates 10 ° from (c), the ridge line portion of the support member 31 passes just below the center of the support member 31, and the ridge line portion presses the heel surface 70a. Indicates the situation that continues. During the transition from (c) to (d), the largest pressure is applied to the upper surface 70a.
