Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a marker storage device for an implanter, and in particular, when the depth of the marker submerged in the soil is adjusted, the position of the locking device that locks the marker in the storage position is automatically set to a new position. And a marker storing device.

[0002]

[Prior Art]

 Generally, the marker of the transplanter is a device that marks the position to be passed next time in the field while moving from one side of the field to the other. Therefore, during the rice planting work in the field, it should be lowered to the field and the position to run next to the rice transplanter should be noted.However, at the working position, it should be overhanged greatly from the machine to the next planting side. There is. For this reason, when the direction of movement is changed in the field, the marker on the side that has already finished rice planting is turned to the pulling up posture. In addition, a marker is stored inside the machine body when traveling on the road, and a locking tool is provided on the machine body side so as to lock the marker.

[0003]

[Problems to be solved by the device]

 However, in the conventional transplanter, when adjusting the depth of planting rice seedlings, and adjusting the depth of the marker submerged in the soil at the same time, the position of the marker is adjusted to the position of the locking tool when storing it. It cannot be locked because it is displaced. Therefore, when the work was completed and the marker was to be retracted, the position of the locking tool had to be adjusted, and the marker had to be returned to the initial position and retracted, which was troublesome.

[0004]

[Means for Solving the Problems]

 The present invention solves such a problem, and when the depth to which the marker is immersed is adjusted, it is possible to obtain a storage device that can move the position of the locking tool that holds the marker in the storage position in conjunction with each other. For the purpose, a connecting shaft 4 for connecting a plurality of floats 4b arranged in the left-right direction to the working machine frame 1b is horizontally mounted, and the connecting shaft 4 is provided with an arm 4a extending rearward and downward. In the transplanter in which the float 4b is supported on the free end of the arm 4a and the marker 5 is rotatably supported on the outer end of the connecting shaft 4, a marker locking rod 4f is provided projecting upward from the connecting shaft 4, The marker locking rod 4f is formed with a marker locking portion 5e, and the marker 5 is stored in the locking portion 5e.

[0005]

[Work]

 The depth of the marker immersed in the soil is adjusted by raising and lowering the float 4b and adjusting the planting depth by the planting depth adjusting lever 4d via the connecting shaft 4. When the connecting shaft 4 is rotated for adjusting the implantation depth, the marker locking rod 4f fixed to this also changes its position by the same angle. Further, since the locking portion 5e of the marker 5 is supported by the marker locking rod 4f, the angle change of the marker 5 is always followed, so that the storage position always follows the angle change of the marker 5 and the phase is not shifted. Absent.

【Example】

 Hereinafter, the invention will be described with reference to illustrated embodiments. In FIG. 1, reference numeral 1 denotes a planting work machine, which is connected to a rear portion of a traveling machine body T forming a riding type rice transplanter through a link mechanism 1a. In addition to the traveling machine body T and the planting work machine 1, the power takeoff shaft of the traveling machine body T and the input shaft (not shown) of the planting work machine 1 are connected via an intermediate shaft S. .. The member B erected at the tip of the aircraft is a reference rod for determining the course of the traveling aircraft T, and serves as a reference for aligning the line marked on the field with the marker with the driver's line of sight. is there.

As shown in FIG. 2 and FIG. 3, the planting work machine 1 has a work machine frame 1b welded to the lower end of the vertical frame forming the link mechanism 1a, and has a drive case 2 extending in the left-right direction. Is pivotably connected in the left-right direction by a longitudinal pivot 1c, and its swing range is restricted by a leaf spring 1d fixed to the work machine frame 1b. Further, the drive case 2 supports a seedling stand 1e that reciprocates in the left-right direction, and a planting unit 3 that drives the planting claw 3b from the drive case 1c via the chain case 3a. A connecting shaft 4 is rotatably supported below the drive case 2 via a substantially triangular bracket 2a.

The connecting shaft 4 connects the respective floats 4b and is made of a steel pipe. A large number of arms 4a extend rearward and downward from the outer surface thereof, and the float 4b is rotated by a pin 4c at the tip thereof. Installed as possible. The arm 4a is provided with a planting depth adjusting lever 4d that extends upward from the connecting shaft 4 and is operated from the driver's seat, and a marker 5 that marks the position of the return path in the field.

As shown in FIG. 4, an auxiliary pipe 4e extending upward is welded to the end of the connecting shaft 4, and the root of the marker 5 is attached to the pin 5a constituting the pivotal support at the outer end of the auxiliary pipe 4e. Therefore, it is pivotally supported so as to be rotatable, and is urged by the spring 5b in the protruding direction. Further, 5c is a Bowden wire for remotely operating the marker 5 to retract it, the inner wire of which is locked to the root of the marker 5 and the outer wire is supported by the bracket 5d. The bracket 5d is welded to the auxiliary pipe 4e.

Therefore, when the inner wire of the Bowden wire 5c is now pulled against the elasticity of the spring 5b, the marker 5 is pulled up from the soil and rotated to the pulling up position in the mode shown in FIG. .. When the inner of the Bowden wire 5c is loosened, the marker 5 is pulled by the elastic force of the spring 5b and protrudes outward as shown in Fig. 6, and the tip of the marker 5 is sunk into the soil and its locus on the paddy field. I will draw.

In FIG. 4, reference numeral 4f denotes a locking rod for locking the marker 5 at the storage position, which is welded to the auxiliary pipe 4e. A locking portion 5e for locking the marker 5 at the storage position is integrally formed on the upper end of the locking rod 4f. That is, the locking portion 5e is U-shaped with the outside of the body closed by a steel pipe, and is formed by bending the upper end portion of the locking rod 4f.

Since this embodiment is configured as described above, the marker 5 is returned from the working position shown in FIG. 6 to the pulling up posture position shown in FIG. 5, and the marker 5 in this state is further manually moved. It is pushed into the inside of the machine body and locked and retained in the U-shaped locking portion 5e.

[0013]

[Effect of the device]

 In the marker storage device according to the present invention, a connecting shaft 4 for connecting a plurality of floats 4b arranged in the left-right direction to the working machine frame 1b is horizontally mounted, and an arm 4a extending rearward and downward is attached to the connecting shaft 4. In the transplanter in which the float 4b is supported at the free end of the arm 4a and the marker 5 is rotatably supported on the outer end of the connecting shaft 4, the marker locking rod is moved upward from the connecting shaft 4. The marker locking rod 4f is provided with a marker locking portion 5e, and the marker 5 is stored in the locking portion 5e.

Therefore, when the burial amount of the marker 5 in the soil is adjusted in the working posture of the marker 5, the locking rod 4f and the locking portion 5e formed on the upper end of the locking rod 4f are correspondingly adjusted. The position will be adjusted accordingly. Therefore, it is not necessary to readjust the marker 5 regardless of whether it is buried in the soil. Further, since the marker locking rod 4f is fixed on the connecting shaft 4 and the marker locking portion 5e is formed at the end thereof, when the marker 5 is raised to the storage position, it can be easily operated by hand. Further, the marker can be locked to the marker locking portion 5e, and the transplanting work in the field and the storing work of the marker 5 during traveling on the road can be efficiently performed.
