[0009]
As shown in FIG. 2 to FIG. 4, the left and right side markers 98 are provided on the side bumper 108 that guards the outermost part of the seedling mounting table 16 so as to be foldable / extendable, and the planting case 20 is connected, A base end frame 112 is fixed on a transmission pipe 109 that accommodates a planting drive shaft, a support column 111 is erected on the base end frame 112, and an upper seedling support shoe 110 is disposed on the upper end of the support column 111. Has been. A base portion of the side bumper 108 is foldably connected to the outer end of the base end frame 112 via a rotation fulcrum shaft 113 and a position restricting pin 114. When the seed bumper 16 is folded and the side bumper 108 is stored, the position restricting pin 114 is removed, the position restricting pin 114 is rotated rearward, and the position restricting pin 114 is inserted and fixed. Is hooked on both side surfaces of the seedling mount 16.
[0010]
A side marker 98 is foldably connected to the distal end side of the side bumper 108 via a support rod 115 which is a marker main body, and the undulation plate 116 at the base end of the support rod 115 is a rotation fulcrum shaft 117. It is connected to the side bumper 108 so as to be freely rotatable. A wire 135 is connected to the support rod 115 side of the undulating plate 116 and connected to the lifting link mechanism of the planting part, and is pulled to accommodate the side marker 98 when the planting part is raised, while the undulating plate 116 is connected. A spring 136 is interposed between the opposite end and the side bumper 108 to urge the side marker 98 in a protruding direction.
[0011]
Further, the marker mounting plate 118 at the base end of the side marker 98 is connected to the tip of the support rod 115 through a rotating shaft 119 so as to be rotatable. Marker refracting between a tip of a rotating arm 120 fixed to the mounting plate 118 in a direction opposite to the side marker 98 and a fixing piece 121 fixed inside a rotating fulcrum shaft 117 provided on the side bumper 108. A marker refracting link 122 as a means is interposed.
[0012]
The distance between the upper attachment point of the refractive link 122 and the rotation shaft 119 is larger than the distance between the lower attachment point of the link 122 and the fulcrum shaft 117, and the side marker 98 is supported by the support rod 115 when the support rod 115 is raised. The rotation angle of the side marker 98 is set to be larger in the direction opposite to the rising direction of the side marker 98 than the rotation angle of the support rod 115.
Therefore, the tip end portion of the side marker 98 does not protrude outward greatly when stored, and can be stored within the body width, and the side marker 98 does not protrude outward when stored. 98 does not catch obstacles, reduces the possibility of contact and damage, reduces running costs by replacing damaged parts, is economical, and allows the operator's attention to be concentrated on the work Therefore, the burden on the operator can be reduced, and safe work can be performed.
A marker storage hook 124 is provided on the mounting plate 123 at the upper end of the support 111 to engage and hold a support rod 115 in the storage state, which will be described later.
[0013]
The refracting link 122 for accommodating and projecting the side marker 98 is made of an elastic body, and is configured such that a force to bend and extend the refracting link 122 always works.
Therefore, the side marker 98 is urged to rotate downward during storage so that the side marker 98 does not protrude outward due to vibration, inertia, or the like. A force to extend due to the elasticity of the link 122 is applied to urge the tip of the side marker 98 so as to always thrust into the soil, and the side marker 98 floats up or jumps on the unevenness or lump of the field. This prevents the lines from disappearing and ensures that the lines can be drawn.
[0014]
Further, as shown in FIGS. 5 to 8, the mounting plate 118 is provided with stoppers 130 and 131 for restricting the angle when the side marker 98 and the support rod 115 are stored and extended. 115.
[0015]
As shown in FIGS. 5 and 6, the stopper 130 is welded and fixed to the mounting plate 118, and when the side marker 98 is stored, the stopper 130 abuts the support rod 115, and more than necessary inside. It is controlled not to rotate. In other words, the side marker 98 is stretched by restricting the pivot arm 120 and the refracting link 122 with the stopper 130 so that the pivot point of the pivot arm 119 and the refraction link 122 does not exceed the extension of the support rod 115 around the pivot shaft 119 (beyond the dead point). When turning it out, it is prevented from rotating in the reverse direction. Furthermore, the refraction link 122 is not pulled more than necessary by the side marker 98 during storage, and therefore it is unnecessary for the joint between the rotating arm 120 and the refraction link 122 and the connecting portion between the fixed piece 121 and the refraction link 122. Since no load is applied, it is possible to reduce the wear of the connecting portion, which is economical. In addition, the side marker 98 rotates inward more than necessary during storage and does not come into contact with the seedling table 16. When the side marker 98 is stored and moved and turned, the side marker 98 is provided. Therefore, the burden on the operator can be reduced.
[0016]
Further, as shown in FIGS. 7 and 8, the stopper 131 is fixed to the upper surface of the outer end of the support rod 115 by welding, and when the side marker 98 is projected, the stopper 131 comes into contact with the mounting plate 118, The side marker 98 is restricted from rotating more than necessary. For this reason, the side marker 98 does not hit the convex portion of the farm scene when overhanging, or hits the soil mass and is not rotated more than necessary.
Thereby, the marking to the stable farm field is possible by the side marker 98. FIG. Since it comprised in this way, the movable range at the time of the overhang | projection of the side marker 98 and the accommodation is controlled. In addition, since it comprises as mentioned above, even when the said refractive link is comprised with an elastic body, the rotation range of the side marker 98 can be controlled.
[0017]
Further, as shown in FIGS. 9 and 10, the mounting plate 123 is fixed to the upper end of the support column 111, and the hook base 134 is pivoted on the mounting plate 123 by a pivot shaft 133 made of a bolt. Further, a spring 132 is externally fitted to the pivot shaft 133, one end of the spring 132 is locked to the mounting plate 123, and the other end is locked to the hook base 134, and the hook base 134 is fixed to the spring 132. It is urged to move upward. The hook base 134 is loosely fitted to the pivot shaft 133 so that the hook base 134 can tilt in the front-rear direction. In addition, a marker storage hook 124 made of an elastic material is fixed to the tip of the hook base 134, and the marker storage hook 124 can be bent by elastic deformation.
[0018]
With this configuration, at the work position where the side bumper 108 is extended to the side, when the side marker 98 is in the storage position, the marker storage hook 124 is attached to the pivot shaft 133 as shown in FIG. The refractive link 122 can be engaged and held only by pivoting to the center sideways. Then, when the side bumper 108 is rotated rearward and the seedling stage 16 is folded, the refraction link 122 is positioned rearward as shown in FIG. 10, so that the hook base 134 is tilted rearward. Thus, the marker storage hook 124 can be engaged with the refractive link 122. Furthermore, the side bumper 108 can be rotated rearward while the marker storage hook 124 is engaged with and held by the refractive link 122 at the working position where the side bumper 108 is extended to the side.
Thus, since the marker storage hook 124 can be rotated back and forth and right and left, it does not impose an unreasonable burden on each part of the refractive link 122, the hook base 134, and the mounting plate 123.
[0019]
【The invention's effect】
Since the present invention is configured as described above, the following effects can be obtained.
That is, since the hook base portion of the side marker storage hook that locks the side marker for drawing at the storage position is configured to be able to turn left and right and back and forth, when holding the side marker in the working state at the stored position, The side marker can be engaged and held by the marker storage hook only by rotating in the left-right direction.
In addition, when the split seedling stage is folded and the side marker base is also folded, the side marker can be easily engaged and held by rotating the marker storage hook to the rear. However, it does not place an excessive burden on each part such as the hook base and link, which reduces the load on each part, reduces the degree of metal fatigue, and extends the usable period of the part. It is economical.
[0020]
In addition, since an elastic member is externally fitted on the pivot shaft of the hook base and the hook base is urged in the direction of the pivot axis by the elastic member, the hook base can be allowed to move back and forth, and attached by the elastic member. The side marker can always be pulled when the marker is stored, so that it will not come off even if vibration or impact occurs in the locked state, and noise may be generated due to vibration or the like. There is nothing.
[0021]
In addition, since the side marker storage hook is made of an elastic body, the refractive link 122 is engaged and held by the marker storage hook 124 after the side bumper 108 is rotated backward in order to restore the original shape even if it is deformed. In this case, the marker storage hook 124 can be bent backward to engage and hold the refractive link 122. Further, since it is difficult to be permanently deformed, the necessity for replacement is reduced, and the running cost is reduced, which is economical.
[0022]
In addition, in the rice transplanter where the side marker can be refracted in the middle, and the side marker is refracted when the side marker is stored, the refracting link that is refracted and extended when the side marker is extended and stored is made of an elastic body. When the side marker is stored, the side marker can be urged to rotate inward and can be stored inside the side bumper. Further, when the side marker is extended and extended, the refraction link urges the side marker to rotate downward, so that the side marker can be reliably pushed into the soil of the field.
Also, even when the side marker is pushed up in a hard field, the refractive link is elastically deformed and the side marker is less likely to break, and it is always biased downward, so it may jump up and break the line Absent. Further, even if the refraction link is deformed and held by the side marker storage hook, it is not permanently deformed, so that the amount of insertion of the side marker into the soil can be changed. Further, since it is difficult to be permanently deformed, the necessity for replacement is reduced, and the running cost is reduced, which is economical.
