  The present invention relates to an offset work machine, an offset mechanism part that is mounted on a traveling machine body and is movable to a position offset in the left-right direction with respect to the traveling position of the traveling machine body, and horizontally on the moving end side of the offset mechanism part. The present invention relates to an offset working machine having a working unit rotatably arranged.

  Such an offset work machine is mounted on a traveling machine body such as a tractor, and when performing a linear coating operation for spreading the field along the traveling direction of the traveling machine body or a groove digging work for digging a groove in the field. Used for. Since the padding work and the grooving work are work performed on the periphery of the field, the work part for performing these work needs to be installed at a position offset laterally with respect to the travel position of the traveling machine body. There is.

  Further, since the plastering work and the grooving work are straight work at the offset position in accordance with the progress of the traveling machine body, the traveling machine body is used when working along the periphery of the field in a rectangular field. When the leading end of the paddle reaches the end of the field, the subsequent work cannot be performed, and an unworked part always remains at the four corners of the rectangular field.

  Therefore, in the case of a spot coater, the present applicant moves the spot coater to the offset work position on the opposite side of the normal work with respect to the traveling machine body and reverses its front-rear relation (reverse reverse), A plastering machine has been proposed that can work while the traveling machine body is moved backward with respect to the unworked portions at the four corners (see Patent Document 1).

  This wrinkle coater has a main body frame extending in the front-rear direction having a connecting portion that is detachably connected to a connecting mechanism provided in the traveling machine body, and a working portion that can be detachably connected to a rear end portion of the main body frame. It has. The working unit includes any one of a left offset work position offset to the left side with respect to the traveling direction of the traveling machine body, a right offset work position offset to the right side, and a storage position on the rear side in the traveling direction of the traveling machine body at the rear end of the main body frame. It can be installed at any position.

Japanese Patent Laid-Open No. 10-4706 (page 3, FIG. 2)

  However, in this conventional coater, when the support frame forming the offset mechanism portion is lengthened in order to ensure sufficient overhanging to the offset work position, the work section is installed in the storage position. The longitudinal direction length of the coater becomes longer, and the center of gravity position of the coater moves to the rear side. For this reason, when the traveling machine body is moved and transported by the traveling machine body being lifted and supported by the traveling machine body, there is a risk that traveling may become unstable due to the inclination of the road surface or riding on obstacles. is there.

  Also, in order to install the work part of the hull coater in a position reversed with respect to the traveling machine body, the work part was once removed from the attachment position of the main body frame during normal work and reversed with respect to the traveling machine body. Attach the working part to the body frame. For this reason, the problem that the installation operation | work which installs the working part reversed and reversed in a work position arises. These problems are the same for the grooving machine.

It can be installed at a storage position that is close to the side and fits behind the traveling machine body, or an inverted offset work position that is reversed of the traveling machine body.

  According to a third aspect of the present invention, in the offset working machine according to the first or second aspect, the offset mechanism portion has one end side rotatably connected to the mounting portion and the moving end side is coaxial with the rotation fulcrum of the frame portion.

And a parallel link mechanism.

  The invention of claim 4 is the invention of the offset working machine according to claim 3, wherein the offset frame of the offset mechanism part and the frame part of the working part include a power transmission mechanism (for example, the power transmission device 30 in the embodiment). It is characterized by that.

  According to a fifth aspect of the present invention, in the invention of the offset working machine according to the third or fourth aspect, the offset frame is a vertical rotation shaft (for example, an embodiment) provided on the link fulcrum in the mounting portion and the rotation fulcrum on the moving end side. And the frame portion includes a winding transmission mechanism having at least a vertical rotation shaft provided at a rotation fulcrum of the connecting portion as a power transmission shaft. To do.

  The invention of claim 6 is the invention of the offset working machine according to any one of claims 1 to 5, wherein the working unit is a pre-processing body (for example, the heaven processing unit 55 and the pre-processing unit 59 in the embodiment) and It is a wrinkle coating work unit provided with a trimming body (for example, the trimming unit 63 in the embodiment).

  A seventh aspect of the present invention is the offset working machine according to any one of the first to fifth aspects, wherein the working portion is a grooving working portion provided with a grooving body.

  According to the offset working machine of the first aspect, the working portion includes a frame portion that extends in a predetermined direction (for example, the offset working position side in the embodiment) from a rotation fulcrum provided on the moving end side of the offset mechanism portion. Thus, as compared with the case of only the offset mechanism unit, the offset working machine according to the present invention can increase the amount of offset movement by which the working unit is offset in the left-right direction of the traveling machine body. In addition, the extending portion of the frame portion is held in a predetermined direction with respect to the movement of the offset mechanism portion, and the frame portion is rotated by the expansion / contraction operation of the expansion / contraction cylinder. By providing a coupling mechanism that rotates with respect to the moving fulcrum, the working unit can be offset-shifted steplessly while the working unit remains in a predetermined orientation with respect to the movement of the offset mechanism, and the frame The working unit can be rotated about the rotation fulcrum of the unit and moved to the left and right sides of the traveling machine body.

  According to the offset working machine of the second aspect, the working unit can be installed at the one-side offset working position and the reverse-side offset working position by moving the offset mechanism and turning the coupling mechanism. The working unit can be installed from the one-side offset work position to the reverse-side offset work position or from the reverse-side offset work position to the one-side offset work position simply by moving and rotating the coupling mechanism. Therefore, the installation work at the work position of the working unit is easy, and the workability of the installation work can be improved. Further, since the offset mechanism portion and the frame portion can be stored in a state where the offset mechanism portion and the frame portion are folded at the rotation fulcrum by moving the offset mechanism portion and rotating the connecting mechanism, the working portion is stored in the rear position of the traveling machine body close to the mounting portion side. The length of the offset working machine in the stored state can be shortened. For this reason, the center of gravity position of the offset work machine can be brought closer to the traveling machine body side, and as a result, when the traveling machine body is moved and lifted and supported by the traveling machine body, It is possible to prevent the possibility of running unstable due to the inclination of the road surface or riding on an obstacle.

  According to the offset working machine of the third aspect, the offset mechanism portion is arranged in parallel with the offset frame, one end side of which is connected to the mounting portion and the moving end side of the offset mechanism portion is coaxially connected to the rotation fulcrum of the frame portion. And having a link member connected to a connecting arm member whose one end side is connected to the mounting portion and whose moving end side is connected to the connecting portion to form a parallel link mechanism, so that the offset mechanism portion and the frame portion are fixed. The extension direction of the frame portion can be held in a predetermined direction with respect to the movement of the offset mechanism portion. For this reason, it is possible to adjust the amount of offset movement of the working unit steplessly while the orientation of the working unit is kept constant in a predetermined direction only by moving the offset mechanism unit. In addition, since the working part is supported by the offset frame and the link member, the rigidity of the offset frame can be reduced compared to the case where the working part is supported by a single offset frame. The machine can be reduced in weight.

  According to the offset working machine of the fourth aspect, by including the power transmission mechanism in the offset frame and the frame portion, the offset work can be performed as compared with the case where the power transmission mechanism is provided separately from the offset frame and the frame portion. The structure of the machine can be simplified, and the entire work machine can be reduced in weight by sharing parts.

  According to the offset working machine of the fifth aspect, the wrapping transmission mechanism having the vertical rotation shaft serving as the power transmission shaft is included in the offset frame and the frame portion, so that the vertical rotation shaft and the power transmission shaft can be used together. Thus, the structure of the offset working machine can be simplified, and the entire working machine can be reduced in weight by sharing parts. In addition, since the power transmitted to the vertical rotation shaft can be transmitted to the winding transmission mechanism and the working unit in the frame part via the winding transmission mechanism, even when the length of the offset frame or the frame part is long, The power transmitted to the vertical rotation shaft can be easily transmitted to other vertical rotation shafts.

  According to the offset working machine according to claim 6, by making the work part a glazing work part having a pretreatment body and a trimming body, the length in the front-rear direction in the storage state is short, and the work is reversed and reversed. It is possible to provide an offset working machine capable of performing a glazing operation with the advantage that the installation work of installing the part at the work position is easy.

  According to the offset working machine of claim 7, the working portion is a grooving working portion provided with a grooving body, so that the working portion that is reversed and reversed in the front-rear direction length in the storage state is the working position. It is possible to provide an offset working machine provided with a working unit capable of grooving work, which has the advantage of being easy to install.

  According to the offset working machine according to the present invention, the working unit has a rotation fulcrum on the moving end side of the offset mechanism unit and includes a frame portion extending from the fulcrum in a predetermined direction (for example, the offset working position side). Thus, the amount of offset movement of the working unit in the left-right direction can be increased. In addition, the connecting portion through the rotation fulcrum of the offset mechanism portion and the frame portion holds the extension direction of the frame portion in a predetermined direction with respect to the movement of the offset mechanism portion, and the frame portion is extended by the expansion / contraction operation of the expansion / contraction cylinder. By providing a coupling mechanism that rotates with respect to the rotation fulcrum, the working unit can be offset-moved steplessly while the working unit remains in a predetermined orientation with respect to the movement of the offset mechanism unit. The working part can be turned around the turning fulcrum of the frame part as the turning center.

  Further, since the working unit can be installed at the one-side offset work position and the reverse-side offset work position by moving the offset mechanism part and turning the connection mechanism, it is only necessary to move the offset mechanism part and turn the connection mechanism. Thus, the work unit can be installed from one offset work position to the other offset work position, and the workability of the work part installation work can be improved. Further, since the offset mechanism portion and the frame portion can be stored in a state where the offset mechanism portion and the frame portion are folded at the rotation fulcrum by the movement of the offset mechanism portion and the rotation of the coupling mechanism, the working portion is stored at the rear position of the traveling machine body approaching the mounting portion side. The length of the offset working machine in the stored state can be shortened. For this reason, the center of gravity position of the offset work machine can be brought closer to the traveling machine body side, and when the traveling machine body is moved and transported by the traveling machine body with the hull coater being lifted and supported, the slope of the road surface It is possible to prevent the possibility of running unstable due to riding on obstacles or obstacles.

  The offset mechanism part is connected to the mounting part at one end side and is connected to the offset frame, the moving end side being coaxially connected to the rotation fulcrum of the frame part, and the one end side is connected to the mounting part for movement. When the offset mechanism part and the frame part are fixed by having a parallel link mechanism having a link member connected to a connection arm member whose end side is connected to the connection part, the movement of the offset mechanism part is prevented. The extending direction of the frame part can be held in a predetermined direction. For this reason, it is possible to adjust the amount of offset movement of the working unit steplessly while the orientation of the working unit is kept constant in a predetermined direction only by moving the offset mechanism unit. Further, since the working portion is supported by the two members of the offset frame and the link member, the rigidity of the offset frame can be reduced, and the offset working machine can be reduced in weight.

  Further, by including the power transmission mechanism in the offset frame and the frame portion, the structure of the offset working machine can be simplified, and the entire working machine can be reduced in weight by sharing parts. In addition, the structure of the offset work machine can be simplified by combining the vertical rotation shaft and power transmission shaft by including a winding transmission mechanism with a vertical rotation shaft serving as the power transmission shaft in the offset arm and frame section. It is possible to reduce the weight of the entire work machine by sharing the parts.

  In addition, by making the working part a glazed working part with a pretreatment body and a trimming body or a grooving working part with a grooving body, the length in the front-rear direction in the storage state is short and inversion It is possible to provide an offset working machine capable of performing a fringing work and a groove digging work, which has an advantage that the installation work for installing the reversed working unit at the work position is easy.

[First embodiment]
First, the wrinkle coater will be described. For convenience of explanation, the directions of the arrows shown in FIG. 1 (perspective view) and FIG. 2 (plan view) will be described below as the front-rear direction and the left-right direction. As shown in FIGS. 1 and 2, the wrinkle coater 1 is connected to a three-point link connecting mechanism (not shown) provided at the rear portion of the traveling machine body 90 so that the traveling machine body 90 moves forward and backward. In accordance with this, the paintwork is performed. The wrinkle coater 1 is mounted on the traveling machine body 90 and includes a mounting part 10 having an input shaft (described later) to which power from the traveling machine body 90 is input, and a turning cylinder 3 provided on the mounting part 10. An offset mechanism 20 that can be moved laterally (left and right), and a power that is transmitted to the moving end side (rear end side) of the offset mechanism 20 so as to be rotatable in the horizontal direction and transmitted from the input shaft. And a working unit 50 that performs work at positions offset to the left and right sides with respect to the traveling position of the machine body 90.

  The mounting portion 10 includes a hitch frame 11 that extends in the left-right direction, and a connection frame 13 that is attached to the front side of the hitch frame 11 and that can be connected to a three-point link connection mechanism provided at the rear portion of the traveling aircraft body 90. . As shown in FIG. 3B (cross-sectional view), a gear box 4 is provided at the lower center of the hitch frame 11 in the left-right direction. The gear box 4 is provided with the input shaft 4a described above, and the input shaft 4a is adapted to transmit power from a PTO shaft (not shown) of the traveling machine body via a transmission shaft (not shown). Yes.

  As shown in FIG. 2, the offset mechanism section 20 is provided side by side along the left side of the offset frame 21 and an offset frame 21 that is rotatably connected to the hitch frame 11 with the front end side as a link fulcrum and extends rearward. The front end side of the hitch frame 11 is rotatably connected to the left end portion, and the rear end side of the offset frame 21 is connected to a connecting portion 23 rotatably provided at the rear end portion of the connecting frame member 23a. Become. The offset mechanism unit 20 forms a parallel link mechanism by the offset frame 21, the link member 25, the hitch frame 11, and the connecting arm member 23a.

  The offset frame 21 is a box-like member having a hollow inside, and a power transmission device to be described later is provided in the offset frame 21. The offset frame 21 can swing in the left-right direction by the expansion and contraction operation of the swing cylinder 3 described above that is pivotally connected between the rear end portion of the offset frame 21 and the left end portion of the hitch frame 11. As shown in FIG. 3A (internal plan view) and FIG. 3B, the power transmission device 30 built in the offset frame 21 is a winding transmission mechanism, and can freely rotate within the front end portion of the offset frame 21. A drive shaft 31 that is disposed and extends in the vertical direction, a drive sprocket 32 that is fixed to an intermediate portion in the vertical direction of the drive shaft 31, and that is rotatably disposed in the rear end portion of the offset frame 21 and extends in the vertical direction. It has a driven shaft 33, a driven sprocket 34 fixed to the intermediate portion in the vertical direction of the driven shaft 33, and a chain 35 wound around the drive sprocket 32 and the driven sprocket 34.

  The drive shaft 31 receives the drive force from the input shaft 4 a via bevel gears 5 and 6 disposed in the gear box 4. For this reason, the driving force from the traveling machine body is transmitted to the driven shaft 33 via the input shaft 4 a, the driving shaft 31, the driving sprocket 32, the chain 35 and the driven sprocket 34.

  A rotation center shaft 7 extending downward coaxially with the driven shaft 33 is connected to the lower portion of the driven shaft 33. That is, the rotation center shaft 7 rotates with the rotation of the driven shaft 33. As shown in FIG. 1, the connecting portion 23 described above is rotatably attached to the lower rear end portion of the offset frame 21. That is, the connecting portion 23 is in a non-coupled state with the rotation center shaft 7 and is rotatable about the rotation center shaft 7 as a rotation fulcrum O. The connecting arm member 23 a described above is connected to the connecting portion 23. At the lower end portion of the rotation center shaft 7 that penetrates the connecting portion 23, there is a working portion 50 having a frame portion 51 that extends from the rotation fulcrum O to the offset work position side with the rotation center shaft 7 as a rotation fulcrum O. Is provided.

  As shown in FIG. 1, the frame portion 51 can be rotated with respect to the rotation fulcrum O by the expansion / contraction operation of the expansion / contraction cylinder 41 of the connection mechanism 40 connected between the connection portion 23 and the frame portion 51. The extension direction of the frame part 51 is held in parallel with the movement of the offset mechanism part 20 by the mechanism 40. The connecting mechanism 40 is connected between the connecting portion 23 and the frame portion 51, and is connected between the rotating link mechanism 42 and the working portion 50 to expand and contract the rotating link mechanism 42. It has a telescopic cylinder 41. The rotation link mechanism 42 is a so-called four-bar link including four nodes, and a portion of the connection portion 23 from the rotation fulcrum O of the connection portion 23 to a position P1 having a predetermined distance on the front end side of the offset frame 21. Is defined as a first node 42a, and the second link 42b is defined between the fulcrums of the first link member 43 pivoted in the left-right direction with the position P1 as a rotation fulcrum. One end side is pivoted so that it can be rotated in the left-right direction, and the other end side is pivotable in the left-right direction with a position P2 having a predetermined distance from the rotation fulcrum O in the extending direction of the frame 51 as a rotation fulcrum. The connected second link member 44 is defined as a third joint 42c, and the portion of the frame portion 51 between the pivot position P2 of the second link member 44 pivoted to the frame portion 51 and the rotation fulcrum O is a fourth joint 42d. It is configured as.

  The first node 42a of the rotation link mechanism 42 is a fixed node, the second node 42b is an input node, the third node 42c is an intermediate node, and the fourth node 42d functions as an output node. The length L2 of the second node 42b that is the input node is longer than the length L4 of the fourth node 42d that is the output node. For this reason, the rotation angle of the fourth joint 42d is larger than the rotation angle of the second joint 42b. That is, the rotation link mechanism 42 has a limited stroke of the telescopic cylinder 41 that swings the second joint 42b, and therefore the fourth joint 42d, that is, the rotation of the frame portion 51 within the swing range of the second joint 42b. It is configured to increase the moving range. More specifically, the second section is such that when the telescopic cylinder 41 is fully contracted, the frame portion 51 extends parallel to the right side, and when the telescopic cylinder 41 is fully extended, the frame portion 51 extends parallel to the left side. The lengths of 42b (first link member 43) and the fourth joint 42d are set.

  The coupling mechanism 40 configured in this way, coupled with the offset mechanism part 20, holds the extending direction of the frame part 51 parallel to the left-right direction with respect to the left and right turning movement of the offset mechanism part 20. That is, the connection mechanism 40 can integrate the connection part 23 of the frame part 51 and the offset mechanism part 20, if the expansion / contraction operation | movement of the expansion-contraction cylinder 41 is controlled in the state in which the frame part 51 extended in the left-right direction. For this reason, when the offset mechanism part 20 pivots in the left-right direction in a state where the frame part 51 and the connecting part 23 are integrated, the frame part 51 is parallel to the left-right direction by the offset mechanism part 20 constituting the parallel link mechanism. It is moved while being maintained. The attachment position of the telescopic cylinder 41 will be described later.

  As shown in FIG. 1, the frame 51 includes a winding transmission mechanism (not shown) having a power transmission shaft as the vertical rotation shaft 52 shown in FIG. 1 to which power from the rotation center shaft 7 is transmitted. ing. Since the winding transmission mechanism in the frame 51 has the same configuration as that in the offset frame 21 described above, the description thereof is omitted. The driving force from the traveling machine body 90 is transmitted to a work main body portion 54 (to be described later) of the working portion 50 via the winding transmission mechanism in the offset frame 21, the rotation center shaft 7 and the winding transmission mechanism in the frame portion 51. . Thus, since the vertical rotating shaft 52 is disposed coaxially with the driven shaft 33, the entire working machine can be reduced in weight by sharing the parts. The driving force from the traveling machine body 90 is transmitted to a work main body portion 54 (to be described later) of the working portion 50 via the winding transmission mechanism in the offset frame 21, the rotation center shaft 7 and the winding transmission mechanism in the frame portion 51. Is done.

  A work main body 54 is connected to a lower end of the frame 51 via a drive shaft case (not shown) extending downward. A power transmission mechanism (not shown) is built in the drive shaft case, and this power transmission mechanism is adapted to transmit power from a winding transmission mechanism in the frame portion 51. The work main body 54 includes a heaven processing unit 55 that cuts off the upper part of the old fence formed along the periphery of the field, a pre-processing unit 59 that piles up the cut soil, and the piled up soil. It has a trimming part 63 to be applied on the old basket.

  As shown in FIG. 2, the celestial processing unit 55 includes a celestial processing rotor (not shown) that is rotatable. The heaven processing rotor is connected to and supported by the drive shaft case via the heaven power transmission case 56. A power transmission mechanism (not shown) is built in the heaven power transmission case 56, and the power from the power transmission mechanism of the drive shaft case is transmitted to the heaven processing rotor via this power transmission mechanism.

  The pre-processing unit 59 has a tilling rotor (not shown) that can freely rotate. The tilling rotor is connected to and supported by the drive shaft case via the pretreatment power transmission case 60. A power transmission mechanism (not shown) is built in the pretreatment power transmission case 60, and the power from the power transmission mechanism of the drive shaft case is transmitted to the tilling rotor via this power transmission mechanism. A fixing member 61 whose one end is fixed to the frame portion 51 and extends to the upper position side of the tilling rotor is provided at an upper position of the pretreatment portion 59, and the telescopic cylinder 41 constituting the connecting mechanism 40 described above is provided on the fixing member 61. The bottom end of the is pivoted.

  The trimming unit 63 has a polyhedral drum 65 attached to a rotating shaft 64 that extends in the left-right direction and is rotatably supported, and a cylindrical portion 66 that is attached to the right end of the polyhedral drum 65 and extends in the lateral direction. . The trimming part 63 is connected to and supported by the drive shaft case via a trimming power transmission case 67. A power transmission mechanism (not shown) is built in the trimming power transmission case 67, and the power from the power transmission mechanism of the drive shaft case is transmitted to the trimming section 63 via this power transmission mechanism.

  The work main body portion 54 is disposed with respect to the frame portion 51 so that the rotation shaft 64 of the trimming portion 63 is parallel to the direction in which the frame portion 51 extends in a state where the frame portion 51 extends in parallel in the left-right direction. Yes. That is, the work main body 54 is arranged so that the work direction axis O2 indicating the direction of the work part 50 is parallel to the traveling direction A of the traveling machine body 90 when the frame part 51 extends in the left-right direction. Has been.

  Next, the operation of the wrinkle coater 1 will be described. For example, when the telescopic cylinder 41 of the coupling mechanism 40 extends when the offset frame 21 of the offset mechanism 20 extends obliquely rearward to the left and the frame 51 extends parallel to the right side in the left-right direction, 4 (a) (plan view), the first link member 43 of the rotation link mechanism 42 rotates in the direction of arrow A (clockwise), and the frame portion 51 moves via the second link member 44. Turns backward. When the telescopic cylinder 41 is further extended and fully extended, as shown in FIG. 4B (plan view), the first link member 43 is further rotated clockwise and the second link member 44 is rotated. The frame portion 51 pivots to a position extending parallel to the left side in the left-right direction.

  As described above, in the plastering machine 1 according to the present invention, the work unit 50 can be rotated about the rotation fulcrum O on the rear end side of the offset frame 21 and the work main body 54 can be rotated by the coupling mechanism 40. Can be moved from one side in the left-right direction to the other side. For this reason, it is possible to move the working unit 50 to the offset position on the side opposite to that during normal work by simply extending and retracting the telescopic cylinder 41 and to reverse the front-rear relationship (reverse reverse). Therefore, the workability of the installation work in which the working unit 50 is reversed and installed can be improved.

  Further, while the work main body portion 54 is held in the reversed and reversed state, that is, with the telescopic cylinder 41 maintained in the fully extended state, the revolving cylinder 3 is reduced and moved so that the offset mechanism portion 20 is revolved in the left-right direction. Then, as shown in FIG. 5A (plan view), the frame portion 51 is integrated with the connecting portion 23 and the connecting arm member 23a, and the frame portion is turned by the turning movement of the offset mechanism portion 20 forming the parallel link mechanism. 51 moves to the left while being held parallel to the left-right direction. As a result, the working unit 50 can be moved to the left-side offset work position where the hulling work can be performed by the backward traveling of the traveling machine body. Further, as shown in FIG. 5B (plan view), when the offset mechanism 20 is turned to the right while the frame 51 is held in parallel in the left-right direction, the working unit 50 is moved to the right with respect to the traveling machine body. It is possible to move the working unit 50 to the right offset work position where the paintwork can be applied to the heel. Further, compared with the case where the working unit 50 is rotatably provided at the rear end portion of the offset frame 21, the coater 1 according to the present invention contributes to the increase in the offset amount by the length of the frame unit 51. Can be made. For this reason, even if the length of the offset frame 21 is shortened, the working unit 50 can be installed at the offset work position.

  Moreover, if the expansion / contraction operation | movement is regulated in the state which extended the expansion-contraction cylinder 41 so that the extending direction of the frame part 51 may become parallel to the left-right direction, The work position adjustment can be performed in a stepless manner while the direction of the work direction axis O2 of the working unit 50 is parallel to the traveling direction of the traveling machine body by only the turning operation in the left-right direction of 20.

  Further, as shown in FIG. 2, when the offset mechanism portion 20 is rotated with respect to the hitch frame 11 and tilted to the left rear side, the offset mechanism portion 20 and the frame portion 51 are broken at the rotation fulcrum O. Since the width dimension in the left-right direction of the coater 1 is reduced and the longitudinal length of the coater 1 is shortened, the coater 1 is stored in the rear position of the traveling machine body 90. Can do. For this reason, the hull coater 1 in the housed state has a shorter length in the front-rear direction, and the center of gravity of the hull coater 1 can be brought closer to the traveling machine body 90 side.
