Description

The present invention relates to a work method for a coater, and more particularly to a work method for a coater that works at a position offset laterally with respect to the travel position of a traveling machine body.

  Such a hull coater is attached to the rear part of a traveling machine body such as a tractor, and moves the working part to a position offset laterally with respect to the traveling position of the traveling machine body to perform the hulling work. In recent years, it has been attracting attention as having achieved mechanization of the lacquering work which requires a great amount of time and labor since it forms cocoons over the entire circumference of a wide field (see Patent Document 1).

  This glazing machine includes a machine frame having an input shaft to which power from a traveling machine body is input, a movable machine frame that is movable in the left-right direction from the machine frame and that holds the working direction of the working unit in a predetermined direction, And a working unit that is provided on the movable machine frame and rotates by the power transmitted from the traveling machine body to perform the smearing operation.

  This padding machine performs a straight line painting operation at an offset position as the traveling body progresses. However, when performing a straight line painting operation along the periphery of the field in a rectangular field, the traveling machine body When the leading end of the paddle reaches the end of the field, the subsequent straight line work cannot be performed, and there is a problem that unworked parts always remain at the four corners of the rectangular field.

  Therefore, in the conventional lacquering machine, the lacquering machine is moved to the offset work position on the opposite side of the normal operation with respect to the traveling machine body, and its front-rear relation is reversed (reversed reverse), so that the four corners are not yet worked. There has been proposed a hulling machine capable of a hulling operation while moving the traveling machine body backward with respect to the portion (see Patent Document 2).

  This wrinkle coater is provided so as to be freely turnable in the left-right direction with a machine frame that is detachably connected to the traveling machine body and a rotation center shaft that extends in the vertical direction on the rear side of the machine frame as a rotation fulcrum. A movable machine frame, a pretreatment rotor disposed on the movable machine frame to cut up the upper part of the old paddle and depositing the soil piled up by the pretreatment rotor on the cut old paddle; And a working part. The working unit can be installed at any one of a left offset work position offset to the left side and a right offset work position offset to the right side with respect to the traveling direction of the traveling machine body via the movable machine frame.

For convenience of explanation, the directions of the arrows shown in FIG. 1 (perspective view) and FIG. 17 (perspective view) will be described below as the front-rear direction and the left-right direction. First, the plastering machine 1 used for the working method will be described.

  The wrinkle coater 1 includes a mounting portion 10 that is mounted on the rear portion of a traveling machine body, which will be described later, an offset mechanism 20 that can swing in the left-right direction from the mounting portion 10, and a moving end side (rear end side) of the offset mechanism 20. And a working unit 50 that is disposed so as to be pivotable in the horizontal direction with the pivot point O provided as a pivot center, and performs a smearing operation with power transmitted from the traveling machine body.

  The mounting portion 10 includes a connecting frame 11 that is mounted on the three-point link connecting mechanism of the traveling machine body, and a hitch frame 13 that is attached to the rear side of the connecting frame 11. An input shaft (not shown) is provided at the lower center of the hitch frame 13 in the left-right direction, and the input shaft transmits power from a PTO shaft (not shown) of the traveling machine body via a transmission shaft (not shown). It has become.

  The offset mechanism 20 is for moving the working unit 50 in the left-right direction with respect to the traveling machine body. The offset mechanism 20 is connected to the hitch frame 13 so as to be rotatable in the left-right direction with the front end as a rotation fulcrum. An offset frame 21 that extends to the side, a link member 25 that is juxtaposed along the left side of the offset frame 21 and that is pivotably connected to the hitch frame 13 in the left-right direction, and a lower portion of the rear end of the offset frame 21 And a connecting arm member 23a connected to a connecting portion 23 that is rotatably provided at a position. The rear end portion of the link member 25 is pivotally connected to the connecting arm member 23a. The offset mechanism 20 forms a parallel link mechanism by the offset frame 21, the link member 25, the hitch frame 13, and the connecting arm member 23a. The offset mechanism 20 can turn in the left-right direction by the expansion and contraction operation of the turning cylinder 3 provided on the offset mechanism 20.

  At the rear end portion of the offset frame 21, a driven shaft 30 that extends in the vertical direction and can be rotated by power from the traveling machine body is disposed. A rotation center shaft 33 that is coaxially connected to the driven shaft 30 and extends downward is provided at the lower portion of the driven shaft 30, and the rotation center shaft 33 that extends downward from the lower end of the rear end of the offset frame 21 includes the connecting portion described above. 23 is rotatably attached.

  The connecting portion 23 is configured such that the frame portion 51 extending from the working portion 50 is integrated with the connecting portion 23 and the working portion 50 is offset while keeping the orientation of the working portion 50 constant, or the frame portion with respect to the connecting portion 23 is The working unit 50 is rotated through the frame part 51 by freely rotating the part 51, and has a connecting mechanism 23 connected between the connecting part 23 and the frame part 51. The connection mechanism 40 includes a rotation link mechanism 41 connected between the connection portion 23 and the frame portion 51, and a connection between the rotation link mechanism 41 and the frame portion 51 to expand and contract the rotation link mechanism 41. And a telescopic cylinder 42 for rotating the working unit 50 via 51. When the expansion / contraction movement of the expansion / contraction cylinder 42 is restricted, the connecting portion 23 and the frame portion 51 can be integrated via the rotation link mechanism 41, and when the expansion / contraction cylinder 42 is expanded / contracted, the working portion connected to the frame portion 51. 50 can be reversed (reversed reverse) with its direction changed from one side of the left and right sides of the traveling machine body 90 to the other side.

  The working portion 50 is attached to the distal end portion of the frame portion 51 in a state where the working portion 50 is fixed to a drive shaft case extending downward, which will be described later. The working unit 50 is provided with a heaven processing 53, a preprocessing unit 60, and a trimming unit 70 from the front side to the rear side. By arranging the respective processing units of the working unit 50 in this way, the soil cut from the upper part of the old paddle by the top field processing unit 53 and the soil cut by the pre-processing unit 60 are piled up, and the trimming unit 70 The soil filled with is painted on the shredded old wall. As shown in FIG. 4 (plan view), when the frame unit 51 extends in the left-right direction, the working unit 50 has the working direction axis O2 indicating the direction of the working unit 50 as the traveling machine body 90 advances. It is arranged so as to be parallel to the direction A.

  As shown in FIG. 2A (plan view), the preprocessing unit 60 and the trimming unit 70 are attached to the drive shaft case 35 described above. That is, the pre-processing unit 60 is attached to the drive shaft case 35 via a pre-processing power transmission case 61 extending in the front-rear direction, and the rectifying unit 70 is connected to the drive shaft case 35 via a rectifying power transmission case 71 extending in the front-rear direction. Is attached. The pre-processing unit 60 is attached with its rotating shaft 60a coupled to the front end of the pre-processing power transmission case 61, and the trimming unit 70 is the tip of the trimming power transmission case 71 'that includes the rotating shaft 70a. Is connected and attached to the rear end portion of the trimming power transmission case 71. That is, the preprocessing unit 60 and the trimming unit 70 are integrally attached to the drive shaft case 35. For this reason, the part which consists of the pre-processing part 60 and the trimming part 70 is compactized, and can reduce the magnitude | size of the whole coating machine. The preprocessing power transmission case 61 is pivotably mounted at the end on the drive shaft case 35 side so as to be pivotable. Between the preprocessing power transmission case 61 and the drive shaft case 35, as shown in FIG. 2B (side view), the vertical position of the preprocessing unit 60 is moved by swinging the preprocessing power transmission case 61 up and down. A possible vertical movement device 63 is provided.

  This vertical movement device 63 has a handle 64 at the top, and when this handle 64 is rotated, the vertical movement device 63 expands and contracts, and the pre-processing power is set with the base end portion of the pre-processing power transmission case 61 as a rotation fulcrum. The transmission case 61 can be swung up and down. For this reason, the pre-processing unit 60 can be moved in the vertical direction via the pre-processing power transmission case 61 by the vertical movement device 63. More specifically, when the handle 64 is rotated and the vertical movement device 63 is contracted, the pre-processing unit 60 is moved to an upper position with respect to the trimming unit 70 as shown in FIG. 2C (side view). Can be made. Here, the movement amount of the pre-processing unit 60 is an amount that can be moved to an upper position at least above the old basket U when the old basket U is painted by the trimming unit 70. On the other hand, as shown in FIG. 3 (side view), when the handle 64 is rotated and the vertical movement device 63 extends, the pre-processing unit 60 can be moved to a lower position with respect to the trimming unit 70.

  As shown in FIG. 1 again, when the power from the traveling machine body 90 is transmitted to the input shaft, the wrinkle coater 1 configured in this way transmits this power to the power (not shown) disposed in the offset frame 21. It is transmitted to the driven shaft 30 via the transmission mechanism and transmitted to the rotation center shaft 33. Then, the power transmitted to the rotation center shaft 33 is transmitted through a power transmission mechanism (not shown) in the frame portion 51 and a power transmission mechanism (not shown) in the drive shaft case, as shown in FIG. 61 is transmitted to a power transmission mechanism (not shown) provided in the power transmission case 71 and drives the preprocessing unit 60 and the trimming unit 70. The power transmitted to the drive shaft case is transmitted to the heaven processing unit 53 via a power transmission mechanism in a heaven processing power transmission case (not shown) to drive the heaven processing unit 53.

Next, a description will be given of a working method of the coater 1 when the side Fa of the rectangular farm field F is applied by the coater 1 according to the present invention. As shown in FIG. 4 (plan view), first, the traveling machine body 90 is installed at a position along one side Fa of the field F. Then, the working unit 50 is offset to the right side of the traveling machine body 90 by the offset mechanism 20 and the connecting mechanism 40 shown in FIG. 1 so that the working direction axis O2 of the working part 50 is oriented in the same direction as the traveling direction A of the traveling machine body 90. Move. Then, the traveling machine body 90 is moved forward and the working unit 50 is driven. As a result, the heaven field processing unit 53 cuts the upper part of the old paddle U on one side Fa of the field F, the pre-processing unit 60 piles up the cut soil, and the soil on which the trimming unit 70 is built up. One side Fa of the field F is smeared continuously on the old straw U.

  Then, when the traveling machine body 90 approaches the front end peripheral position 90a of the field F and the traveling direction of the traveling machine body 90 changes, the frame part 51 is made rotatable with respect to the coupling part 23 by the coupling mechanism 40 shown in FIG. 1 is extended to rotate the working unit 50 with respect to the offset mechanism 20 so that the direction of the working direction axis O2 of the working unit 50 does not deviate from one side Fa of the field F. For this reason, the work part 50 can move to the edge part along one side Fa of the agricultural field.

  Here, when the working unit 50 moves to the end of one side Fa of the field F (50b), the trimming unit 70 moves in the portion B of the old basket U between the heaven field processing unit 53 and the trimming unit 70. Since it is an area where it cannot be applied, it is not possible to perform the haze painting operation, and an unworked portion remains at the end of the old hail U.

  However, when the working unit 50 reaches the corner of the field F (50b), the position of the pre-processing unit 60 is set to the old basket U by the vertical movement device 63 shown in FIG. By moving the adjusting section 70 while moving the position of the working unit 50 to the other old scissors U ′ side by moving the position of the working section 50 by swinging the offset mechanism 20, The unworked portion B of the old tack U can be smeared. For this reason, it is possible to perform the glazing operation up to the end of the old ridge U.

  In addition, the attachment position of the pre-processing part 60 and the shaping part 70 is not restricted to the positional relationship mentioned above, There exist various types. Below, these various positional relationships are demonstrated. First, as shown in FIG. 5A (plan view), an adjustment power transmission case 71 ′ including the rotation shaft 70 a of the adjustment unit 70 is arranged so as to be orthogonal to the rotation center axis of the drive shaft case 35. Thus, the front end of the trimming power transmission case 71 ′ is attached to the side surface of the drive shaft case 35, and the trimming power transmission case 71 ′ extending between the trimming portion 70 and the drive shaft case 35 is attached to the preprocessing unit 60. A front end portion of a preprocessing power transmission case 61 ′ extending to be connected to the rotation shaft 60a is rotatably attached. Then, as shown in FIG. 5B (plan view), a vertical movement device 63 is provided between the preprocessing power transmission case 61 ′ and the drive shaft case 35. As a result, as shown in FIG. 5C (plan view), the up-and-down moving device 63 can move the preprocessing unit 60 to an upper position with respect to the trimming unit 70.

  Further, as shown in FIG. 6A (plan view), the trimming portion 70 is disposed at a position close to the drive shaft case 35 and the tip of the trimming power transmission case 71 ′ is placed on one side of the drive shaft case 35. It is attached to the side portion of the drive shaft case 35, the end portion of the pretreatment power transmission case 61 is rotatably attached to the other side portion of the drive shaft case 35, and the pretreatment portion 60 is attached to the tip portion of the pretreatment power transmission case 61 As shown in FIG. 6B (plan view), a vertical movement device 63 may be provided between the preprocessing power transmission case 61 and the drive shaft case 35. As a result, as shown in FIG. 6C (plan view) and FIG. 7 (plan view), the vertical movement device 63 moves the preprocessing unit 60 to the upper position and the lower position with respect to the trimming unit 70. be able to.

  Further, as shown in FIG. 8A (plan view), the preprocessing power transmission case 61 of the preprocessing unit 60 is juxtaposed with the trimming power transmission case 71 ′, and one end side end of the preprocessing power transmission case 61 is arranged. Is provided on the drive shaft case 35 so that the other end side end of the preprocessing power transmission case 61 is disposed in the vicinity of the trimming unit 70 and extends from the preprocessing unit 60 to the other end side end. A processing power transmission case 61 ′ may be attached, and a vertical movement device 63 may be provided between the preprocessing power transmission case 61 and the drive shaft case 35 as shown in FIG. 8B (plan view). As a result, as shown in FIG. 8C (plan view), the up-and-down moving device 63 can move the preprocessing unit 60 to an upper position with respect to the trimming unit 70.

  Further, as shown in FIG. 9A (plan view), a pre-processing power transmission case 61 ′ extending from the pre-processing unit 60 is attached to the side surface of the drive shaft case 35, and is attached to the tip of the rectifying power transmission case 71 ′. The side surface of the end portion on one end side of the attached trimming power transmission case 71 is rotatably attached to the side surface of the drive shaft case 35, and as shown in FIG. A trimming unit vertical movement device 63 may be provided between the drive shaft case 35 and the drive shaft case 35. As a result, as shown in FIG. 9C (side view) and FIG. 10 (side view), the adjusting unit 70 is moved upward and downward relative to the preprocessing unit 60 by the adjusting unit vertical movement device 63. Can be moved to.

  When the trimming unit 70 is provided so as to be movable up and down with respect to the preprocessing unit 60 in this way, as shown in FIG. 11 (plan view), it is smeared from one corner Fa of the field F along one side Fa. When working, the trimming unit 70 is moved to a position above the preprocessing unit 60 by the trimming unit vertical movement device 63 shown in FIG. Other than connecting the traveling machine body 90 to the old fence U by installing the pre-treatment part 60 and the heavenly treatment part 53 at the corner of the field. When the celestial processing unit 53, the preprocessing unit 60, and the trimming unit 70 are driven, the celestial processing unit 53 and the preprocessing unit 60 perform a predetermined range preprocessing. After that, the trimming unit 70 can perform the glazing operation from the end of the other old scissors U ′. For this reason, an unworked portion does not occur at the end of the old tack U ′ at the start of the tacking operation, and the end of the old tack U ′ can be reliably smeared.

  Moreover, although the case where the traveling machine body 90 moves forward is described in the above-described practical form, the plastering machine 1 according to the present invention travels as shown in FIG. 12 (plan view). It is possible to perform the glazing operation while moving the body 90 backward. In this case, the working unit 50 moves from the right position to the left position of the traveling machine body 90 shown in FIG. When the working unit 50 moves to the corner of the field, as shown in FIGS. 13 (a) (side view) and (b) (front side front view), the pre-treatment unit 60 is indicated by a broken line as shown in FIG. Move to the upper upper position. Then, as described above, the end portion of the old tack U is painted by the trimming section 70 while the traveling machine body is moved backward. As described above, the plastering machine 1 according to the present invention can coat the end of the old tack U while moving the traveling body 90 backward.

  Moreover, as shown in FIG. 14 (plan view), FIG. 15 (a) (side view) and (b) (front side front view), the plastering machine 1 of the present invention moves the pretreatment unit 60 in the vertical direction. As a means to make it, you may provide the up-and-down moving apparatus 63 'with the parallel link mechanism 65. The parallel link mechanism 65 is provided between the pre-processing unit 60 and the trimming unit 70, and is rotatably connected to a trimming power transmission case 71 ′ disposed coaxially with the rotation shaft of the trimming unit 70. The member 66 connected between the preprocessing power transmission case 61, the drive shaft case 35, and the preprocessing unit 60 is configured as a pair of link members. Thus, by moving the preprocessing unit 60 up and down via the parallel link mechanism 65, the preprocessing unit 60 can be moved up and down without changing the posture of the preprocessing unit 60.

  The parallel link mechanism 65 described above is aligned with respect to the preprocessing unit 60 as shown in FIGS. 16A (plan view), (b) (side view), and (c) (front side view). You may provide so that the part 70 may be moved to an up-down direction. In this case, the parallel link mechanism 65 has a trimming power transmission case 71 and a member 66, one end side end portion of which is pivotally connected to the drive shaft case 35, and the other end side end portion thereof is regulated by the trimming power. It pivots to the transmission case 71 ′. As a result, by moving the trimming unit 70 up and down via the parallel link mechanism 65, the trimming unit 70 can be moved up and down without changing the posture of the trimming unit 70.

  In addition, in the above description, the plastering machine 1 capable of performing the smearing operation while the traveling machine body is moved forward or backward is described. However, as shown in FIG. 17, the smearing work can be performed only when the traveling machine body is moved forward. It is also possible to use a wrinkle coater 80 for forward movement. This wrinkle coater 80 is shown in FIG. 1 in that the working unit 50 having no frame 51 shown in FIG. It is different from the coater 1 and is common to the coater 1 shown in FIG. 1 in other parts.

  In such a hull coater 80, the pre-processing unit 60 can be moved to the upper upper position of the old hammer, and the trimming unit 70 can be moved to the upper upper position of the old hammer, as shown in FIG. By providing the vertical position adjusting device 63 shown in FIG. 4, the same effects as those of the above-described coater 1 can be obtained.
