BACKGROUND OF THE INVENTION
The present invention relates to a support device for a preliminary roll in a multi-transplanter that supports a pre-roll that is a replacement sheet roll provided in the multi-transplanter.
[0002]
[Prior art]
Conventionally, a transplanting machine is connected to the rear of a traveling machine body having a driver's seat and a driving step, and a sheet that rolls out as the traveling machine body covers the field scene is rolled into the transplanting machine and the traveling working machine. A multi-implanting machine is known in which a sheet roll formed on each side and a support device for a preliminary roll, which is a replenishment sheet roll, are mounted, and the support frame of the preliminary roll in the support device is arranged along the side of the traveling machine body. It has been publicly known that it can be switched between a preliminary roll retracted posture position and a preliminary roll supply posture position to the transplanting machine that has been displaced in a direction crossing the traveling machine body.
[0003]
[Problems to be solved by the invention]
However, since the support frame is accommodated in the retracted posture position and extends to the side of the driver's seat and the driving step when the spare roll is not attached, the worker is required to get on and off the driving step. Once the support frame is opened (posture displacement toward the supply posture position) to secure a boarding / alighting space from the side to the driving step, boarding / exiting to the driving step is performed, and the support frame is closed after boarding / exiting ( There is a drawback in that it is not easy to get on and off the driving step because it is necessary to perform an operation of changing the posture from the supply posture position side to the retracted posture position.

[0006]
DETAILED DESCRIPTION OF THE INVENTION
1 to 3 are an overall side view, a main part side view, and an overall plan view of a multi-planter (rice transplanter), and a driver's seat is mounted on the body frame 4 of the traveling body 1 supported by the front and rear wheels 2 and 3. 6 and an operation step 7 are provided, and a planting work machine 9 which is a transplanting work machine is attached to the rear of the traveling machine body 1 via a lifting link 8 so as to be movable up and down and rolling. The planting work machine 9 is obliquely provided with a seedling stand 11 whose upper end is inclined forward, and the planter case 12 is provided with a mat seedling at the lower back of the seedling stand 11 as the traveling machine body 1 travels. A known planting part 13 for sequentially scraping and transplanting is attached.
[0007]
On the other hand, on the bottom surface of the planting work machine 9, a sensor roller 14 that automatically controls the swing of the lifting link 8 to support the planting work machine 9 at a predetermined height is supported horizontally by the equalizer arm 16, and At the front upper position of the sensor roller 14 is attached a cylindrical sheet case 18 that rotatably supports a sheet roll 17 in which a paper sheet made of cardboard recycled paper or the like is formed in a roll shape so as to be rotatable in the horizontal direction. It has been.
[0008]
The multi-grafting machine having the above structure lowers the planting work machine 9 on the field so as to support the planting machine 9 at a predetermined height, and sequentially feeds the paper sheets 19 from the sheet rolls 17 while the traveling machine body 1 is running. The seedlings 13 are scraped off from the mat seedlings by the planting unit 13 while the surface is covered, and the seedlings are planted from the top of the paper sheet 19 and transplanted (multi-transplanting) into the field.
[0009]
Note that a sheet cutter 22 is provided at a rear position of the planting work machine 9 and supported by the rear end of the cutter arm 21 pivotally supported on the side of the planting work machine 9. The paper sheet can be cut at the covering end position by swinging the rear end up and down and lowering the sheet cutter 22 to the field scene.
[0010]
As in the prior art, the left and right ends of the seat case 18 are configured to be openable and closable, and by opening one of the end portions, the sheet roll 17 is inserted into the seat case 18 from either of the open end portions. The sheet case 18 can be inserted, that is, the sheet roll 17 can be replaced (supplemented) by inserting the sheet roll 17 into the sheet case 18 from the side.
[0011]
In this embodiment, a support device 24 that supports a spare roll 23 that is a sheet roll for replacement (replenishment) is provided on both the left and right sides of the traveling machine body 1. The sheet roll can be exchanged by moving from 24 to the seat case 18 from the side of the seat case 18. Note that the support device 24 of the present embodiment is configured so that a total of two preliminary rolls 23 can be mounted one on each of the left and right sides of the traveling machine body 1.
[0012]
The support device 24 is provided on a vertical stay 27 erected from the axle case 26 of the rear wheel 3, a horizontal stay 28 supported on the upper end side of the vertical stay 27, and on the left and right end sides of the horizontal stay 28. The holder 29 and the bowl-shaped support frames 31 attached to the left and right holders 29, respectively. The spare roll 23 is supported by the left and right support frames 31 and mounted on the support device 24. ing. Both holders 29 are located on the rear side of the traveling machine body 1.
[0013]
The support frame 31 has a boss 31a provided at one end rotatably fitted to a fulcrum shaft 30 provided on the holder 29, and is rotatably attached to and supported by the holder 29, as will be described later. The auxiliary roll 23 and the support frame 31 are configured to support the auxiliary roll 23 such that the auxiliary roll 23 and the support frame 31 are substantially parallel to each other and the axes of the auxiliary roll 23 are substantially parallel to each other.
[0014]
That is, the preliminary roll 23 is substantially parallel to the support frame 31 when mounted on the support device 24, while the support frame 31 has the other end (free end) with the rear side of the traveling machine body 1 as a rotation fulcrum as described above. ) Side is supported with respect to the traveling machine body 1 so as to be capable of opening and closing in the left-right direction.
[0015]
As shown in FIG. 3, the support frame 31 has a preliminary roll storage posture position A along which the preliminary roll 23 and the support frame 31 are along the side of the traveling machine body 1, and the preliminary roll 23 and the support frame 31 are on the axis of the seat case 18. The posture can be freely switched to a preliminary roll supply posture position B which is displaced in a direction intersecting the traveling machine body 1 so as to be substantially along (substantially parallel).
[0016]
Particularly, when the support frame 31 is switched to the supply posture position B (posture displacement) in a state where the planting work machine 9 is raised, the auxiliary roll 23 and the axis of the seat case 18 are flat as shown in FIG. When viewed from the side, the axis of the auxiliary roll 23 and the center (axis) of the seat case 18 are substantially matched when switched to the retracted posture position A as shown in FIG.
[0017]
As a result, when the planting work machine 9 is raised and the support frame 31 is set to the supply posture position B, the axes of the preliminary roll 23 and the seat case 18 substantially coincide with each other, and the preliminary roll 23 is linearly inserted into the seat case 18. The sheet roll can be easily exchanged. At this time, the front end (free end) of the support frame 31 is set to a length that ensures the boarding / alighting space S from the side to the operation step 7 in the retracted posture position A.
[0018]
Next, the support structure of the preliminary roll 23 in the support frame 31 will be described. The support frame 31 is provided with contact portions 32 and 33 that contact a part of the preliminary roll 23 in the vertical direction with a predetermined distance apart in the axial direction of the support frame 31, and the upper contact portion 32 is the preliminary roll. A part of the upper part of the rear side of the rear part 23 (the rotation fulcrum side of the support frame 31) and a part of the lower part of the contact part 33 are in contact with a part of the auxiliary roll 23 on the lower side of the rear part.
[0019]
That is, both the abutting portions 32 and 33 support the upper and lower circumferential surfaces on the rear end side of the preliminary roll 23 with a predetermined distance apart in the axial direction, so that the preliminary roll 23 is cantilevered on the support frame 31. It has a structure that is stably supported without play. As shown in FIG. 1, a support stay 34 that supports the front end side of the preliminary roll 23 is provided on the front side of the traveling machine body 1, and the support frame 31 to which the preliminary roll 23 is attached is in the storage posture position A. In some cases, the front end side of the auxiliary roll 23 is supported, and the auxiliary roll 23 is stably stored.
[0020]
At this time, the abutment portions 32 and 33 form an opening portion 36 that exposes a part of the peripheral surface of the auxiliary roll 23 in the axial direction between the upper and lower sides. The auxiliary roll 23 is supported on the support frame 31 through the opening 36 by supporting the auxiliary roll 23 on the support frame 31 in correspondence with the tape 35 or the like (see FIG. 4) that prevents looseness. The tape 35 and the like can be easily peeled off in the state of being left.
[0021]
With the structure shown above, the auxiliary roll 23 is mounted on the support frame 31 and the support frame 31 is set to the retracted posture position A, so that the auxiliary roll 23 is placed on either the left or right side of the traveling machine body 1 or on the left or right side. In a cantilever state, the planting work machine 9 is raised and the support frame 31 is placed in the supply posture position B while the spare roll 23 is mounted on the support frame 31. The operator can easily insert the spare roll 23 into the sheet case 18 (replace the sheet roll) while supporting the unsupported end side of the supported spare roll 23.
[0022]
On the other hand, when the spare roll 23 is not mounted, the support frame 31 is rotated to the storage posture position A and stored along the side of the traveling machine body 1. At this time, the length of the front end of the support frame 31 is the same as that described above. Therefore, a boarding space S from the side to the driving step 7 is secured in front of the support frame 31, and the support frame 31 is opened (posture displacement to the supply posture position B side). In addition, the driver can easily get on and off the driving step 7.
[0023]
Thereby, when exchanging the sheet roll, the distance that the operator (driver) walks in the field is shortened and the workability is improved. However, since the length of the support frame 31 is relatively short, the support device 24 is reduced in weight, Usability has been improved.
[0024]
The support frame 31 is provided with an insertion portion (not shown) into which the pipe-shaped or bowl-shaped preliminary roll 23 can be inserted, and the preliminary roll 23 configured by the two contact portions 32 and 33 as described above is supported. Instead of the portion, the support portion of the preliminary roll 23 may be configured by the insertion portion. At this time, the preliminary roll 23 is positioned in the insertion portion in contact with the upper and lower peripheral surfaces of the insertion portion at a predetermined distance in the axial direction of the preliminary roll 23.
[0025]
On the other hand, as shown in FIG. 5, a driving force is input to the drive shaft 41 of the planting work machine 9 from the traveling machine body 1 via the PTO shaft 42 and the intermediate shaft 43. The shaft 43 is connected to the intermediate shaft 43 and the drive shaft 41 via a joint 44 via a joint 44, respectively. The joint 44 is rotatably supported at one end by a link holder 48 to which an upper link 47 constituting the elevating link 8 is connected, and the other end is connected to an arm 51 connected to the upper link 46 through a rod 49. It is fixed.
[0026]
As a result, when the planting work machine 9 shown in FIG. 5A is raised, the upper link 47 pushes down the rod 49 and the arm 51 is tilted forward, and the planting work machine 9 shown in FIG. 5B is lowered. When the upper link 47 pulls down the rod 49 and the arm 51 moves upward, the arm 51 swings and the bending angle of the intermediate shaft 43 with respect to the drive shaft 41 does not change greatly when the planting work machine 9 is lifted and lowered. The rotation of the drive shaft 41 (drive of the planting work machine 9) is configured to be stable.
[0027]
【The invention's effect】
According to the structure of the present invention configured as described above, a space for getting on and off from the side to the operation step is secured in the retracted position of the support frame in front of the support frame. When not mounted, there is an advantage that the driver can easily get on and off the driving step without opening the support frame (posture displacement toward the supply posture position).
[0028]
In addition, since the support frame supports the preliminary roll at the upper and lower contact portions separated by a predetermined distance in the axial direction, the preliminary roll can be stably supported without play. By providing an open part that continuously exposes a part of the surface in the axial direction, it is possible to easily peel off the tape or the like that prevents the spare roll from being scattered while the spare roll is supported by the support frame. There is also an advantage.
