Description

  The present invention relates to a brush coater having a trimming body for shaping a kite, in which the upper surface trimming unit for shaping the upper surface of the kite has a function of compacting the surface soil of the kite surface. This is related to the machine body.

  The finishing body of the coater has a truncated cone shaped slope leveling section and a cylindrical top surface trimming section connected to the tip thereof, and rotates around the axis when the coater runs, so that the pretreatment body The old earthen soil loosened in advance is reshaped as a wall with a slope and an upper surface. At that time, the trimming body is given a rotation speed that can be rolled at a speed faster than the traveling speed of the coater, so that the slope and the upper surface are rolled by slip rotation and the surface soil is consolidated. .

  As the trimming body rotates by the slip, the slope trimming section and the top trimming section apply pressure to both the slope and the top of the kite, so that the surface soil is consolidated and the stability of the shaped kite is improved. Secured. For this reason, the tightened wrinkles can be shaped as pressure is applied to the slope and upper surface of the wrinkles from the trimming body (see Patent Document 1).

  However, the soil tries to slide to the slope side due to the pressure applied from the upper surface, and the reaction force at that time can be received by the slope trimming unit. A certain compaction effect can be obtained (see Patent Documents 2 and 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. 3163269 (Claim 6, paragraphs 0063 to 0067, FIG. 8)

  In any of Patent Documents 1 to 3, since a dynamic pressure is applied to the soil by hitting the top surface of the kite using a drop or a step when the trimming body rotates, there is no possibility of disturbing or scattering the surface soil. It can not be said. If the soil is scattered, there is a possibility of affecting the adjacent fence that has been shaped.

  In addition, it is effective to increase the density of the soil in order to consolidate the soil on the upper surface of the ridge, so if the soil on the upper surface can be brought to the slope without removing it to the periphery, the soil consolidation effect will be improved. It is done. However, in Patent Documents 1 to 3, since only the rotation of the trimming body around the axis is used to apply pressure to the upper surface of the saddle, it cannot be expected that the soil on the upper surface is brought closer to the slope side.

  In view of the above background, the present invention proposes a trimming body for a glaze coater that statically applies pressure to the soil on the top surface of the trough and allows surplus soil to be moved to the slope side.

According to the first aspect of the present invention, there is provided a trimming body according to a first aspect of the present invention, wherein a truncated cone-shaped slope trimming section for shaping the slope of the bowl by rotation around an axis, and a rotation with the slope trimming section connected to a tip of the slope trimming body. In a glazing machine provided with a styling body composed of an upper surface styling part for shaping the upper surface of the candy,
A feature of the present invention is that a spiral groove is continuously formed on the surface of the upper surface trimming portion from the front end portion to the slope trimming portion side.

  Specifically, the spiral groove formed on the surface of the upper surface adjusting portion is, as described in claim 3, a normal surface adjustment from the front end portion from the front to the rear in the direction in which the upper surface adjusting portion rotates. A groove with an inclination toward the buttock side. Since the grooves of the upper surface adjusting part are formed continuously, no difference appears in the direction of the grooves when the upper surface adjusting part is viewed from above, or when viewed from the front or the back. For example, when the brush coater advances in the direction in which the leveling body (upper leveling part) rolls, the leveling body rotates on the plane in the direction of travel of the brush coater. It is the direction of travel of the coater, and its front indicates the forward direction of travel of the coater.

  Therefore, the inclination of the groove on the surface of the upper surface adjusting portion from the front side to the rear side in the direction of rotation toward the slope adjusting portion side means that the groove is rotated along with the rotation of the adjusting body, that is, the upper surface adjusting portion. It means that the soil existing inside is formed in a direction to be conveyed to the slope trimming unit side in a screw conveyor manner.

  The inclination of the groove is the direction in which the soil on the upper surface of the ridge is fed to the slope side by the rotation of the upper surface adjustment section (the adjustment body), but is not necessarily related to the direction of the progress of the glazing machine. In principle, the upper surface trimming portion rotates so as to roll in the direction of travel of the coater. In this case, the groove is formed in the direction of the left-hand thread as shown in FIG. However, when the upper surface leveling portion rolls in the direction opposite to the direction of advance of the wrinkle coater, the groove is formed in the direction of the right-hand thread as shown in FIG. In either case, the groove on the surface of the upper surface trimming part is formed in such a direction that the soil is fed to the slope trimming part side by rotation around the axis, so that the surplus soil existing on the upper surface of the upper surface trimming part is It is sent to the slope side during shaping by rotation.

  Groove is continuously formed means that the groove on the surface of the upper surface adjustment part is continuously formed up to the slope adjustment part side without being interrupted, and there is a discontinuous part of the groove in part. , Including that it is formed intermittently to the extent that it can be regarded as continuous as a whole. The upper surface adjusting portion having the groove is formed, for example, by scraping the outer peripheral surface of a material having a cylindrical original shape into a spiral shape or forcibly pressing from the outside. Alternatively, a coil spring having no rigidity between one-pitch strands and having a rigidity that does not easily bend and deform is used as it is as the upper surface trimming portion. In any case, the material of the material is not limited, and a metal material or a synthetic resin is used.

  The surplus soil sent to the slope side by the rotation of the groove on the top surface trimming part is applied to the slope surface by the slope surface trimming part that shapes the slope, and is consolidated, so that the top surface trimming part covers the top surface. Combined with rolling, the soil compaction effect of the entire fence is improved. As a result, it is possible to firmly finish the slope even in the case of a ridge made of soil that is easy to collapse (slip failure). At the same time, it is possible to finish the surface of the ridge and the slope smoothly and improve the appearance.

  In particular, when the spiral groove is continuously formed from the upper surface adjusting part to a part of the slope adjusting part as described in claim 2, as shown in FIG. Since the soil fed to the slope trimming section is guided to the slope and continuously pressed against the slope by the slope trimming section, it is at the boundary between the top trimming section and the slope trimming section. There is no stagnation of the soil. “Forming up to a part of the slope trimming part” means that a spiral groove is formed up to a part of the frustoconical shape near the top (corresponding to a connecting part 22 described later).

  In the first to third aspects, since the upper surface trimming part statically presses the upper surface of the heel by rotating around the axis, unlike the case of dynamically pressing as in the case of giving a striking force, the upper surface earth and sand are scattered. There is no. Since there is no scattering of earth and sand, there is no effect on adjacent and finished reeds.

  As described above, when surplus soil is sent to the slope side, the upper surface trimming section rotates by slip, and the surface between the grooves rolls downward vertically, so that the soil on the upper surface of the trough is also consolidated. Become. At this time, the range in contact with the upper surface of the ridge is divided into a plurality of peaks in the axial direction by a groove continuously formed from the tip of the upper surface grading portion to the slope grading portion side. The crest portion is pressed evenly in the axial direction of the upper surface trimming portion, and the upper surface of the heel is consolidated.

  In particular, when the portion (mountain) between the grooves on the surface of the upper surface trimming portion has a convex curved surface toward the surface side as described in claim 4, the peak portion divided by the groove is an arc surface. Therefore, there is an advantage that the effect of pressing the upper surface of the heel by rotation is improved. In this case, the crests on the surface of the upper surface adjustment part repeatedly flow in the axial direction from the tip side of the upper surface adjustment part to the slope adjustment part side by rotation, so that the surface crests have a convex curved surface. The rolling effect by doing is expected over the entire length of the upper surface trimming part.

  The surplus soil on the upper surface of the cocoon surface is formed by continuously forming a spiral groove from the tip to the slope surface adjustment side on the surface of the upper surface grading portion that constitutes the grading body and shapes the upper surface of the heel Can be sent to the slope trimming section, so that the density of the soil forming the ridge can be increased and a strong ridge can be finished. Further, the upper surface trimming portion statically rolls the upper surface while feeding the soil on the upper surface to the slope side by rotation, so that the scattering of the soil does not occur as in the case of dynamic rolling.

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

  FIG. 1 shows a truncated cone-shaped slope grading section 2 that shapes the slope 40b of the ridge 40 by rotation around the axis, and rotates together with the slope grading section 2 connected to the tip thereof. In the scissor coater provided with the trimming body 1 composed of the top surface trimming section 3 for shaping 40a, the spiral groove 4 is continuously formed on the surface of the top surface trimming section 3 from the tip to the slope trimming section 2 side. The outline of the trimming body 1 single body currently formed is shown.

  As shown in FIG. 6, the main body 10 is basically connected to the rear part of the tractor via a three-point link hitch mechanism, and the parallel connection frames 11 and 11 and the parallel connection frames 11 and 11 are connected to each other. The hitch frame 12 is connected in the width direction of the coating machine, and the offset frame 13 is connected to the rear of the hitch frame 12 so as to be swingable around a vertical axis.

  A connecting material 14 projects from the tip of the offset frame 13 on the rear side of the coater body 10 in the width direction of the coater body 10, and is parallel to the offset frame 13 between the connecting material 14 and the hitch frame 12. A link frame 15 is installed. 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 constructed between the hitch frame 12 and the tip position of the offset frame 13 and is connected to both of the hydraulic cylinders 16. By the expansion and contraction, 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. 7, the work machine 30 of the wrinkle coater is mainly coaxial with the driven shaft 18 at the tip of the offset frame 13 and is connected to a drive box 301 having a transmission shaft 35 to which power is transmitted from the driven shaft 18. It is composed of a frame 1 and a pretreatment body 302 that protrudes forward from the drive box 301 with respect to the trimming body 1 in the traveling direction and loosens the earth and sand of the old bowl prior to shaping of the trimming body 1. The pretreatment body 302 has a claw cutting claw 302a that rotates by receiving power from the drive box 301, and the claw claw 302a cuts the earth and sand of the old claw at a position in front of the trimming body 1 while the work machine 30 is running. It is prepared for shaping by the trimming body 1 by loosening.

  As shown in FIG. 6, an arm 33 projecting toward the trimming body 1 is connected to a connecting portion of the connecting member 14 to the link frame 15, and the work machine 30 is connected between the arm 33 and the drive box 301. A working machine hydraulic cylinder 34 that swings with respect to the coater body 10 is installed and connected to both. The work machine 30 is directed in an arbitrary direction by expansion and contraction of the work machine hydraulic cylinder 34.

  A rotating shaft to which power is transmitted from the transmission shaft 35 is disposed in the drive box 301, and the slope adjusting portion 2 of the adjusting body 1 is connected to the rotating 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. 8, the slope trimming unit 2 is formed in a truncated cone shape as a whole by connecting a plurality of fan-shaped blades 21 with each other at their straight portions, and at the central portion that is the tip position. Is a reference for positioning when a plurality of blades 21 are connected, and a connecting portion 22 for connecting to the upper surface trimming portion 3 is arranged. The connecting portion 22 is in a state of protruding from the slope trimming portion 2 to the upper surface trimming portion 3 side.

  A screw hole 22a for connection with the upper surface adjusting portion 3 by a bolt 5b or the like is formed on the end surface of the connecting portion 22 on the upper surface adjusting portion 3 side, and the upper surface adjusting portion 3 is shown in FIG. As shown, the bolt 5b penetrating in the axial direction is screwed into the screw hole 22a to be connected to the connecting portion 22. The bolt 5b does not need to pass through the entire length of the upper surface trimming portion 3, but forms an insertion hole through which the bolt 5b is simply inserted from the end surface on the front end side of the upper surface trimming portion 3, and is closer to the front surface trimming portion 2 By forming a screw hole into which the bolt 5b is screwed, the length of the bolt 5b can be shortened.

  When the bolt 5b 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 one of the outer peripheral surfaces 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 It can be rotated around an axis and directly connected to the connecting portion 22 in a replaceable manner.

  As shown in FIG. 2A, the adjusting body 1 and the adjusting body 1 are rotated when the groove 4 is continuously formed from the upper surface adjusting section 3 to the tip of the slope adjusting section 2 as described above. The state of the movement of the soil on the ridge upper surface 40a when performing is shown. (A) shows an example in which the inclination of the groove 4 is close to vertical and the angle formed with the rotation axis is close to 90 °, but the inclination of the groove 4 is arbitrarily set, as shown in (b) The angle formed with the rotation axis may be about 45 °. The closer the inclination of the groove 4 is to the horizontal, there is an advantage that the movement distance (lead) of the soil during one rotation of the upper surface trimming part 3 can be gained.

  FIG. 3A shows a case where a coil spring having a shape in which the wire diameter of the strands is large and one pitch strands are in contact with each other is used as the upper surface trimming portion 3. When using a coil spring as an off-the-shelf product, since the coil spring does not have a screw hole for screwing the bolt, it is joined to the connecting portion 22 of the slope adjusting portion 2 by a method that does not depend on the bolt, such as welding. Is done.

  FIG. 3B is a spiral view of the outer peripheral surface of the material 3A having a cylindrical original shape by using a rolling machine as shown in FIGS. An example in the case where the groove 4 is formed is shown. In FIG. 4A, a cylindrical die (round die) 50 is arranged on both sides in the diameter direction of the material 3A, and the die 50, 50 on both sides are rotated in the same direction, thereby rotating in the opposite direction. In this method, the spiral groove 4 is formed in 3A. (B) is a method of forming the groove 4 in the material 3A by sandwiching the material 3A between two plate-shaped dies (flat dies) 50 and 50 and moving one of the dies 50 in parallel. In addition to the method of forming the grooves 4 on the outer peripheral surface of the material 3A, there is also a method in which cutting is directly made on the outer peripheral surface while rotating the material 3A around the axis.

  FIG. 5- (a) shows that while forming the upper surface trimming portion 3 from a cylindrical core material 31 having a flange 31b formed on one end face of the cylindrical portion 31a and a coiled surface material 32 wound around the outer periphery thereof. An operation procedure when the upper surface trimming unit 3 is connected to the slope trimming unit 2 will be described.

  The coil-shaped surface material 32 is formed by heating a bar material such as a synthetic resin round bar such as an acrylic resin, or a metal round bar or a square bar and bending it into a coil shape. Since the synthetic resin has a property that the adhesion of the soil is smaller than that of the metal material, the suitability as the upper surface trimming portion 3 having a function of feeding the soil of the upper surface 40a to the slope 40b is high. In FIG. 5, for the sake of simplification, the strands of the surface material 32 are represented as plate-like, but the strands are actually rod-shaped.

  The end faces of the one-pitch strands positioned at both ends in the axial direction of the surface material 32 ensure a contact area between the receiving material 23 fixed to the tip position of the sloped surface adjusting portion 2 and the flange 31b of the core material 31. Therefore, it is cut off on a flat surface. Since the one-pitch strands positioned at both ends in the axial direction of the surface material 32 are joined to the flange 31b of the core material 31 facing each other and the receiving material 23 at the tip of the slope adjusting portion 2 by bolts 5a. The insertion hole 32a is formed. Insertion holes 31c and 23a are also formed in the flange 31b of the core member 31 corresponding to each insertion hole 32a and the receiving member 23, respectively.

  The receiving member 23 is fixed at the boundary position with the connecting portion 22 at the tip of the slope trimming portion 2, and the connecting portion 22 protrudes from the surface of the receiving member 23 toward the core 31. A screw hole 22a is formed in the end face of the connecting portion 22 in the axial direction. The screw hole 22a passes through the flange 31b of the core member 31 and is screwed with a bolt 5b that passes through the inside (hollow portion) of the surface member 32. The bolt 5 b passes through an insertion hole 31 d formed near the center of the flange 31 b of the core material 31.

  The connecting portion 22 is inserted on the inner peripheral side of the cylindrical portion 31a, such as inscribed in the cylindrical portion 31a of the core member 31, and ensures an overlap margin with the cylindrical portion 31a. The core material 31 is joined to the connecting portion 22 in a state where the overlapping margin between the cylindrical portion 31 a and the connecting portion 22 is adjusted, and the axial length of the upper surface trimming portion 3 is the overlapping margin between the cylindrical portion 31 a and the connecting portion 22. Determined by the length of Depending on the length of the overlap between the cylindrical portion 31a and the connecting portion 22, the threaded length (tightening) of the bolt 5b passing through the insertion hole 31d of the core member 31 and screwed into the screw hole 22a of the connecting portion 22 is secured. Amount).

  The length in the axial direction of the upper surface trimming portion 3 can be changed by changing the length of the cylindrical portion 31a as shown in FIG. 5- (b) in addition to the overlap margin between the cylindrical portion 31a and the connecting portion 22. Thus, by preparing a plurality of core members 31 having different lengths of the cylindrical portion 31a, it is possible to form the upper surface trimming portion 3 corresponding to the width of the upper surface 40a to be shaped. . Moreover, the length of the upper surface trimming part 3 is finely adjusted by adjusting the overlap margin between the cylindrical part 31a and the connecting part 22 for each core 31 having a different length of the cylindrical part 31a.

  Since the surface material 32 is formed in a coil spring shape and is capable of extending and contracting in the axial direction, it follows the adjustment of the overlap allowance between the cylindrical portion 31 a and the connecting portion 22. As the length of the bolt 5b is shorter (the screwing length is larger), the surface material 32 is compressed in the axial direction, so that the strands of the surface material 32 become dense and the distance (pitch) between the wires is shortened. Is done.

  If the end face of the cylindrical portion 31a of the core member 31 comes into contact with the receiving member 23 at the time when the bolt 5b is tightened into the screw hole 22a, excessive tightening of the bolt 5b is prevented and the surface in the tightened state. The stability of the material 32 and the core material 31 is ensured.

  The flange 31b of the core material 31 and the one-pitch strands of the surface material 32 opposed thereto are connected by a bolt 5a having a length penetrating through the insertion holes 31c and 32a. Similarly, the one-pitch strands of the receiving member 23 and the surface member 32 facing the receiving member 23 are connected to each screw hole 23a by a bolt 5a having a length penetrating the insertion hole 32a.

  In the state where the surface material 32 is connected to the receiving material 23 and the flange 31b of the core material 31 and the core material 31 is connected to the connection portion 22, the upper surface trimming portion 3 is completed. At this time, the rigidity of the upper surface trimming part 3 and the characteristics such as pressure, pitch (lead) to the soil of the upper surface 40a due to the soil, and the total length in the axial direction are based on the material of the surface material 32 itself, and the core It can be freely adjusted by the length of the cylindrical portion 31a of the material 31. For this reason, if a plurality of core members 31 having different lengths of the cylindrical portion 31a are prepared as shown in FIG. It can be changed in the field.
