Description

[Detailed Description of the Invention] The present invention relates to a device for holding and storing a line marker provided on a rice transplanting work machine in its non-working position in a riding rice transplanter.

In a riding rice transplanter in which a rice transplanting machine is attached to the rear of the traveling vehicle via a lift mechanism so that it can be raised and lowered, a line marker pivotally supported on the rice transplanter is connected to the lift mechanism, and the line marker performs the lifting action. In the case of a marker that moves up and down in conjunction with It is actuated by elasticity, and with this configuration, the raised position of the line marker is in an upright position roughly along the outside of the seedling stand, and beyond the upright position, from the outer edge of the seedling stand. Since it cannot be positioned inside and is held by a wire, it is prone to vibration and is unstable. Therefore, during planting work and when driving on the road, the line marker, which is in an upright position and protrudes laterally from the seedling stand, may be damaged by hitting an obstacle such as a high ridge or cliff, or the marker support may be damaged due to machine vibration. There were defects such as deformation of the mechanism. For this reason, a holding mechanism has been proposed in which the line marker is stored and held in a non-working position inside the rice transplanting machine, but the driver must get out of the driver's seat each time the line marker is stored and held or released. Since the markers are switched and stored, the operation is complicated, troublesome, and inefficient.

In view of the conventional deficiencies as described above, and with the aim of improving this, the present invention is designed to provide a retaining tool for holding a line marker to the seedling stand support member installed on the back side of the seedling stand of a rice transplanting machine. The drawing marker is provided so that the tip end of the drawing marker is elastically stored and held against the elasticity of the marker member itself and the elasticity of the marker extension spring, and the drawing marker storage member is The locking operation and locking release operation can be performed quickly and easily from the driver's seat.

29 is a hydraulic lever for operating the hydraulic cylinder 7. When the rice-transplanting work machine 5 is raised by hydraulic operation, the line marker 16 is erected by the movement of the outer wire 17 and placed in an intermediate erected position B along the outer edge of the seedling platform 33. When the rice-transplanting machine 5 descends and comes into contact with the rice field, the machine body is extended to the side by operating the marker lever 27 and held in the working extended position A. Reference numeral 30 denotes a frame erected at the front of the rice transplanting machine 5, and a slide piece 32 that comes into contact with an upper rail 33a provided on the back side of the seedling stand 33 is erected on a seedling stand holding stay 31 provided at the upper end of the frame. A seedling stand support member S is formed which supports the seedling stand 33 which moves back and forth from side to side by the seedling stand holding stay 31, frame 30, etc. from the back side. Reference numeral 34 is a marker locking holder for holding the line drawing marker 16 in a non-working position C which is further inward from the intermediate standing position B, and one end of the locking holder 34 is attached to a seedling stand. It is fixed to the left and right ends of the mounting stay 31, bent into a U-shape in plan view with the free end facing forward, and the line drawing marker 16
The rod-shaped portion can be hooked onto the U-shaped portion to be stored and held against the elasticity of the marker member itself and the elasticity of the marker extension spring 16b. When locking and releasing the locking holder 34, the driver holds and releases the marker 16 by holding the tip of the marker 16 while sitting in the driver's seat 3.

The present invention is configured as described above, and the rice transplanting machine 5 is driven while being lowered to the ground on the rice field, while the machine body is moved forward to carry out the planting work, and when one stroke of planting is completed, the machine When the rice-transplanting machine 5 is rotated, when the planting clutch is disengaged and the hydraulic lever 29 is set to the raised position, the piston rod 8 protrudes and the rice-transplanting machine 5
rises. At this time, the piston rod 8 moves the nuts 15b, 15b of the marker actuating members 15, 15 from the position shown by the solid line in FIG. 2 to the position shown by the chain line in FIG. Since the outer receivers 17a and 17a, which are integrated with 15, also move rearward, the line drawing marker 16, which is in the working position A and extends out to the side of the machine, is pulled by the inner wire 18 and stands up against the extension spring 16b. Also, the lock member 20,
When the marker actuating members 15, 15 move rearward, the locking members 20, 20 are successively pushed up by the bent portions 15a, 15a and rotate upward against the spring 21, and the engaging recesses 22 of the locking members 20, 20 are folded. Music section 15
a, 15a, and the line drawing marker 16 is held upright in an intermediate upright position R along the outer edge of the seedling stand 33.

When the machine rotates in this state and the next stage of planting is to be carried out, when the hydraulic lever 20 is set to the lowered position, the piston rod 8 is retracted and the rice transplanter 5 is lowered, but the marker actuating members 15, 15 are not activated as shown in Fig. 2. As shown in FIG. 2, the left and right markers 16, 16 are kept in the standing position in the intermediate standing position (b) because they are locked in the rearwardly protruding position.

Therefore, when the marker lever 27 is tilted toward the planted area, for example, to the right in FIG.
6 is pulled up, the locking member 20 on the left side separates from the bent portion 15a, and the outer stop 17a of the outer wire 17 on that side is pulled together with the marker operating member 15 due to the weight of the drawing marker 16 and the elasticity of the marker extension spring 16b. Returning to the front, the delineation marker 16 on the unplanted area side falls down from the intermediate standing position B shown by the solid line in FIG. At the same time as the planting work is carried out, a line is drawn on the rice field on the side of the unplanted area. In ordinary fields, delineation work is carried out along with planting work as described above, but for example, when planting work is performed adjacent to obstacles such as high ridges or cliffs, or when entering and exiting the field at an angle from a high farm road. When doing so, while holding the line marker 16 on the side with the disability in the standing position B,
A part of the marker protrudes from the aircraft body, and there is a risk that this protruding part may collide with the above-mentioned obstacle and be damaged, so move the line marker 16 from the standing position B to the non-working position C. It is necessary to store and hold the entire marker in order to reliably prevent collisions. In such a case, the driver, while sitting in the driver's seat 3, grasps the tip of the line drawing marker 16,
If this is hooked to the inner locking holder 34, it can be easily hooked with one hand. At that time, the line drawing marker 16 is attached to the marker extension spring 16.
The line-drawing marker 16 is easily rotated about the pivot portion 16a along the back surface of the seedling stand 33 against the elastic force of b, and is housed and held in the locking holder 34.
The elasticity of the marker member itself and the spring 16
It is reliably held by the reinforced bias of b. In addition, when delineating an unplanted area along a path where obstacles are not adjacent, quickly remove the delineation marker 16 from the locking holder 34 in the reverse procedure to the above, and then operate the marker lever 27. As mentioned above, both locking and releasing can be done quickly and easily with one hand.

Incidentally, when driving on the road, the left and right line marking markers 16, 16 may be housed and held in their respective locking holders 34, 34 in the same manner as the above-mentioned procedure, and the line drawing markers 16 may be protruded outward from the aircraft body. In addition to allowing safe driving without causing any
4 and 34, it is possible to prevent deformation and damage due to body vibration.

4 to 6 show a second embodiment, in which the marker locking holder 35 is bent toward the back side of the seedling stand 33, and when storing and locking the drawing marker 1, , the tip of the marker 16 is the seedling stand 33
It is designed so that it can be locked to the holder 35 while being guided by the back surface, and when the marker 16 is stored by extending the hand from the driver's seat 3, the tip of the marker is connected to the holder 35 and the seedling. Since the marker 16 is guided between the seedling platform 33 and slid along the back side of the seedling platform 33, there is no risk of the marker 16 being bent unexpectedly, and there is no risk of straining the pivot portion of the marker 16. It can be locked with the locking holder 35. Further, since the free end of the locking holder 35 is hidden toward the rear side of the seedling stand 33, there is no risk of injury to the driver or an assistant who supplies the seedlings by getting caught in the free end.

FIG. 7 shows a third embodiment, in which a marker locking holder 37 is pivotally attached to the tip of a bracket 36 provided on a seedling holding stay 31.
The locking holder 37 is made of a clip-shaped elastic plate with an Ω-shaped cross section, and is configured to swing freely around the pivot pin 38, so that the marker 16
can be reliably held in its non-working position.

The lines shown in FIGS. 8 and 9 are line-drawing markers related to the present invention that have improved compatibility with soft rice fields. A marker 41 is attached to the marker 41, which rotates using the pad 40 as a cushioning material, and a wide plate piece 41a is welded to the front surface of the marker 41, and the bottom edge of the plate piece 41a presses against the rice field to form a wide groove. is formed, and it is possible to obtain clear grooves over a long period of time even in soft rice fields where marker lines tend to disappear without being buried by the surrounding mud.

In this way, the rice transplanting work machine is attached to the rear of the traveling vehicle body via a lift mechanism so that it can be raised and lowered freely, and the base of the long bar-shaped line marking marker with a line drawing part formed at the tip is attached to the body of the rice transplanting work machine. a working posture (a) in which the marker is pivoted and the delineated part of the marker is extended to the side of the aircraft;
A marker overhang that is movably attached to an intermediate standing position (B) substantially along the outer edge of the seedling platform and a non-working position (C) stored in the rice transplanting machine, and urges the line drawing marker in the direction of the working position (A). A spring is provided, and the movement of the line drawing marker from the working position A to the intermediate standing position B is linked to a lifting operation of lifting the rice transplanting machine by the lifting mechanism against the elasticity of the marker extension spring. In the riding rice transplanter, a marker locking holder for locking and holding the line drawing marker in the non-working position C is provided on the seedling stand support member disposed on the back side of the seedling stand of the rice transplanting machine. A drawing marker storage device for a riding rice transplanter, in which a rod-shaped portion of the drawing marker is elastically stored and held against the elasticity of the marker itself and the elasticity of the marker extension spring. Although it has a simple structure of simply installing a marker holding lock on the body side of the rice transplanting machine, the line-drawing marker, which is in an upright position on the outside of the seedling table, can be moved to the storage position inside the seedling table. Change operations and vice versa can be easily and reliably changed with one touch from the driver's seat, and can be used as delineation markers when planting in fields close to obstacles such as ridges or cliffs, or when entering and exiting fields. The above-mentioned posture change operation can be performed quickly and efficiently without the hassle of having to get out of the driver's seat each time, and when driving on the road, the delineation marker can be moved to the side. By storing and holding the marker without protruding, it is possible to drive safely, and it is also possible to prevent deformation and damage of the marker due to vibration, and when storing the marker in a non-working position, it resists the elasticity of the marker itself and the elasticity of the marker extension spring. Since the marker is securely held and locked, there is no risk of it coming off unexpectedly or making vibration noise.
In addition, since the marker locking holder is installed using existing seedling stand support members such as the seedling stand support stay required to support the seedling stand, a special attachment is required separately as the attachment member for the marker locking holder. Installing parts,
There is no need to worry about installation space, and it can be easily and inexpensively installed on existing components by welding, etc., and can be installed inconspicuously from the outside.In addition, the line marker can be placed in a comfortable position approximately along the seedling stand. It has extremely useful practical effects, such as being able to store and lock it with one hand.
