Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a marker device provided between a traveling body and a seedling mounting table, and more specifically, a traveling reference index for the next stroke is attached to a tip of a vertically rotating marker arm protruding to the side of the body. The present invention relates to a marker device in a transplanter provided with a rotating body marker formed on a surface.
[0002]
[Prior art]
Generally, a transplanting machine such as a riding rice transplanter for planting seedlings in a field along with the running of the airframe is used to perform a seedling planting operation in an orderly manner. Side markers are provided.
[0003]
Such side markers are drawn with a rod-shaped drawing tool provided at the tip of the marker arm, but when water is stretched relatively deeply on the rice field, the line drawn on the rice field may become turbid. May be difficult to see. In view of this, there is known a rotary marker which is provided at a tip of a marker arm and is orthogonal to a rotatable marker instead of a rod-shaped drawing tool.
[0004]
However, in the case where the rotating body marker is provided at the end of the marker arm in an orthogonal shape, even if the marker arm is moved upward to store the rotating body marker between the traveling body and the seedling mounting table, it is necessary to plant the rotating body marker with the traveling body. The space between the attached parts is made as small as possible to make the whole transplanter compact, so there is not enough space to store the rotating body marker that has become the horizontal storage posture with the upward movement. However, there is a fear that the rotating body marker may come into contact with the rear wheel of the traveling machine or the seedling mounting table of the planting part.
[0005]
Therefore, conventionally, in order to secure a storage space for the rotating body marker, the planting part is necessarily lowered backward to increase the distance between the seedling mounting table and the traveling machine, so even if the rotating body marker can be stored, There is a problem in that the balance between the front and rear of the body is deteriorated, and the head-up amount of the body during operation is increased.
[0006]
[Problems to be solved by the invention]
The present invention has been made in order to solve the conventional problems as described above, and even if a rotating body marker is provided at the tip of a marker arm that rotates up and down, the marker arm is raised. When moving, the rotating body marker should not contact the rear wheel of the traveling machine or the seedling platform of the planting part, and the planting part should be as close as possible to the traveling machine to make the whole transplanter compact. It is an object of the present invention to provide a marker device in an implanting machine capable of performing the above-mentioned.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, a technical measure taken by the present invention is to provide a marker arm which is vertically protruding to the side and pivots vertically between a traveling machine and a seedling mounting table, and is provided at a tip of the marker arm. A rotating body marker is provided, and when the marker arm is moved down, the rotating body marker having an action posture protruding laterally is rotated on the mud surface to form a traveling reference index, and when the marker arm is moved up, traveling is performed. A rotating body marker in a storage position between the machine body and the seedling mounting table can be folded in the front-rear direction with respect to the marker arm. It is characterized in that it can be folded on the table side, and further, a fixing member for switching and fixing the rotating body marker between the operating position and the folding position is provided on the front side of the marker arm. It is intended.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of the present invention will be described in detail with reference to the accompanying drawings of one embodiment. First, in FIGS. 1 to 3, reference numeral 1 denotes a traveling body of a riding rice transplanter exemplified as a transplanter, and an engine part covered with a bonnet 5 on a front part of a body frame 4 having a front wheel 2 and a rear wheel 3. 6 is mounted, and a driver's seat 7 is provided behind it. Reference numeral 8 denotes a steering handle, 9 denotes a center marker erected at the center of the front end of the bonnet 5, and 10 denotes auxiliary seedling stands erected on both sides of the front of the body.
[0009]
At the rear of the body frame 4, a multiple-row planting section 12 is mounted to be movable up and down via a link mechanism 11 including an upper link 11 a and a lower link 11 b. The seedling-planting section 12 includes a seedling table 13 arranged in a front-to-back and rear-to-bottom state, a horizontal frame 14 for the planting section, a plurality of rows of planter cases 15 supported on the lower surface thereof, and the planter case. The planter 16 includes a planter 16 which is mounted on the rear end of the planter 15 and operates, and a float 17 arranged below the planter case 15 for leveling the rice field.
[0010]
Reference numeral 18 denotes a seedling mounting stay that supports the back side of the seedling mounting base 13, 19 denotes an apron guard / stand, and 20 denotes a frame. Reference numeral 21 denotes a hydraulic cylinder disposed between the hydraulic device on the machine body side and the link mechanism 11, and the seedling placement section 12 is moved up and down by the expansion and contraction operation of the hydraulic cylinder 21.
[0011]
Further, between the rear end of the traveling machine body 1 and the seedling mounting table 13, left and right marker arms 22 protruding laterally and rotating vertically are provided, and a rotating body marker 23 is provided at a tip of the marker arm 22. As shown in FIG. 4, the rotating body marker 23 is attached and the rotating body marker 23 is moved from the working posture (a) orthogonal to the marker arm 22 projecting sideways to the non-working posture (b) as shown in FIG. ), It is freely rotatable over an upwardly retracted storage position (c) located between the traveling machine body 1 and the seedling mounting table 13. In the drawing, the rotating body marker 23 in the stored posture is further folded rearward to be in the folded posture.
[0012]
That is, the marker arm 22 is vertically rotatably mounted on both left and right sides of the seedling mounting section 12 via the mounting section 24, and the left and right rotating body markers 23 are mounted on the tip of the marker arm 22. However, the rotating body marker 23 is configured by radially projecting a hook-shaped projection 26 for scooping up a mud surface on the outer periphery of a rotating body 25 formed in a wheel shape. In the operation posture orthogonal to the marker arm 22 projecting to the side, the rotating body marker 23 that is in contact with the mud surface rotates the mud surface as the aircraft travels, and the hook-shaped protrusion 26 scoops the mud surface. The running reference index is raised and formed.
[0013]
Further, an operation wire 27 is connected to the marker arm 22 so that the left and right marker arms 22 automatically and alternately project to the side in conjunction with the raising and lowering of the seedling placement section 12, or The operation posture in which the marker arm 22 in an arbitrary direction is protruded to the side by operating a lever (not shown) is the same as in the related art. Reference numeral 28 denotes a marker hook that locks the marker arm 22 rotated upward at a position where the rotating body marker 23 is in the retracted posture.
[0014]
In the upright position where the marker arm 22 is rotated upward, the rotating body marker 23 mounted on the tip of the marker arm 22 is horizontal and located between the traveling machine 1 and the seedling mounting table 13. However, according to the present invention, the rotating body marker 23 can be folded in the front-rear direction so as to be parallel to the marker arm 22 so that the rotating body marker 23 and the traveling body 1 can be folded. It can be stored in a narrow space between the seedling mounting table 13.
[0015]
Further, by making the rotating body marker 23 foldable toward the seedling mounting table 13 behind the marker arm 22, the rotating body marker 23 can be stored between the marker arm 22 and the seedling mounting table 13. That is, as shown in FIGS. 5 to 7, a pin 29 is attached to the tip of the marker arm 22 so as to be rotatable back and forth around the spring pin 30, and the rotating body marker 23 is rotatably attached to the tip of the pin 29. It is pivoted. The marker arm 22 is provided with a linear pin 29 and a fixing member 31 which comes into contact with the marker arm 22 and prevents the pin 29 from rotating back and forth. The fixing member 31 is turned sideways. It can be released by moving.
[0016]
Therefore, as shown in FIG. 5, the rotating member marker 23 can always be fixed to the operation posture orthogonal to the marker arm 22 by the fixing member 31 as shown in FIG. 5, and when the marker arm 22 is moved upward and stored, as shown in FIGS. When the fixing member 31 is rotated to the side to release the fixing, and the pin 29 is rotated to the rear, the rotating body marker 23 in the storage position is folded toward the seedling table 13 behind the marker arm 22. It can be in a folded position.
[0017]
By providing the fixing member 31 toward the front side of the marker arm 22, that is, toward the traveling body 1, the operator can sit on the driver's seat 7 by raising the seedling-planting part 12 at the time of circling the body. The rotator marker 23 can be folded while being pressed.
[0018]
With the above-described configuration, in performing the transplantation operation, if one of the left and right marker arms 22 is moved downward to protrude the rotating body marker 23 to the side, the rotating body marker 23 is moved with the running of the body. Rotates on the mud surface. At this time, the hook-shaped projection 26 protruding from the outer periphery of the rotating body 25 scoops up the mud surface and raises the running reference index in the next process, so that even if water is spread relatively deeply on the rice field, it is sure In this way, the reference line can be recognized, and the transplant operation can be performed orderly.
[0019]
When the marker arm 22 is moved up and stored, if the fixing member 31 provided on the marker arm 22 is rotated to the side, the rotating body marker 23 is moved along the seedling mounting table 13 from the horizontal upward movement posture. Since the foldable posture can be folded, the rotating body marker 23 does not abut on the seedling table 13 of the seedling mounting part 12 or the rear part of the traveling machine 1. For this reason, the whole transplanting machine can be made compact by bringing the seedling placement section 12 closer to the traveling machine body 1.
[0020]
When the rotating body marker 23 is folded behind the marker arm 22, that is, on the side of the seedling mounting table 13, the rotating body marker 23 in the storage position by moving the marker arm 22 upward is moved to the marker arm 22 and the seedling. Since it can be stored compactly with the mounting table 13, the narrow space between the traveling machine body 1 and the seedling planting section 12 can be used more effectively.
[0021]
Further, since the fixing member 31 of the rotating body marker 23 is provided toward the front side of the marker arm 22, that is, toward the traveling body 1, the seedling placement part 12 can be raised when the body circulates at the ridge. The operator can fold the rotating body marker 23 with one touch from the traveling body 1 side while sitting in the driver's seat 7, thereby improving the working efficiency.
[0022]
【The invention's effect】
In short, the present invention provides a marker arm, which projects sideways and pivots up and down, between a traveling machine and a seedling mounting table, and a rotating body marker is provided at the tip of the marker arm, and a marker below the marker arm is provided. When moving, the rotating body marker of the working posture protruding sideways rotates on the mud surface to form a running reference index, and when the marker arm is moved up, it is located between the running body and the seedling mounting table. The rotating body marker in the storage posture is foldable in the front-rear direction with respect to the marker arm, and the rotating body marker is foldable on the seedling table side behind the marker arm, and further, the front side of the marker arm. In addition, a fixed member that switches and fixes the rotating body marker between the working posture and the folding posture is provided, so that the marker arm is moved upward, and the rotating body marker in the stowed posture is moved forward and backward. If it is folded, it can be placed almost in line with the seedling mounting table, so that the rotating body marker does not come into contact with the planting section or the traveling machine, and therefore, the planting section is brought closer to the traveling machine. As a result, the entire transplanter can be made compact.
[0023]
In addition, in the case where the rotating body marker is foldable to the seedling table side behind the marker arm, the rotating body marker in the storage position moved upward can be folded and stored between the marker arm and the seedling mounting table, so that the traveling machine And the space between the seedling mounting table can be used more effectively.
[0024]
Furthermore, in the case where the fixed member of the rotating body marker is provided on the front side of the marker arm, the operator sitting in the driver's seat can easily switch the rotating body marker in the storage position from the traveling body side to the working position and the folding position. Can be fixed.
