Description

TECHNICAL FIELD The present invention relates to a storage device for a wire drawing marker in a paddy field working machine such as a submerged soil direct seeder (seeder) or a riding rice transplanter.

Conventional techniques and problems In paddy work machines such as direct sowing machines for submerged soil and riding rice transplanters, wire drawing markers are erected up and down on the left and right sides of the working parts such as seeders and planting parts. The line marker on the work site side is tilted to the side (the marker on the already-worked site side is upright) to run while drawing a line on the paddy field, and the line is used as an index in the next stroke to allow the aircraft to travel, making it an appropriate adjacent line. I try to secure a space. During work, it is necessary to switch the left and right wire drawing markers alternately between the working position and the non-working position by operating the lever, etc. every time the aircraft travels, but the wire drawing marker is generally an elongated and lower end of a flexible rod-shaped body. Since the part is pivotally supported on the working machine side, it is easy to swing due to inertia during the tilting operation, and in particular, when the marker is erected from the working posture to the non-working posture, there is a tendency that the marker overruns toward the inside of the fuselage. Therefore, during the standing operation, the marker is often abruptly set in the storage hook fixed to the working machine side, which hinders the wire drawing work.

SUMMARY OF THE INVENTION Therefore, according to the present invention, in the present invention, a working unit 3 such as a seeding unit and a planting unit is connected to the rear of the traveling machine body 1, and the wire drawing marker 10 is attached to the working unit 3 so as to be up and down. In this paddy working machine, a marker receiver 15 is elastically displaceably attached to the working portion 3 at a position where the marker 10 is tilted up and down, and the wire drawing marker 10 is attached to the marker receiver 15 in a non-acting posture while standing. Stopper part to receive
15a is provided so as to project into the up-and-down movement locus of the wire drawing marker 10, and the hook portion 15b that locks and fixes the wire-drawing marker 10 in the retracted state of the non-working posture is positioned away from the up-and-down operation locus of the marker. At the same time, when the marker is stored, the above-mentioned problem is solved by providing it so as to project to the position where the marker can be locked due to the elastic displacement in the locus of raising and lowering the marker.

When the vehicle is running on a road or when the season is off, the wire drawing marker is erected and hooked on the hook portion of the marker receiver to be stored therein. At that time, the marker holder is pulled to hook the hook portion on the marker. During the wire drawing work, the hook part is removed from the marker and the marker receiver is returned to the original state. Since the hook portion is provided so as to be retracted from the raising / lowering operation locus of the marker, even if the marker swings due to inertia or the like during the raising / lowering operation, it does not get caught on the hook portion. Further, an abnormal operation such as an overrun due to inertia during the operation of the marker is stopped and blocked while being buffered by the stopper portion provided in the marker receiver.

Example The drawings show a submerged direct sowing machine in which a sowing section (working section) 3 is connected to the rear of a traveling machine body 1 via a three-point link mechanism 2. A plurality of seed hoppers 4 are mounted in the width direction with respect to the seeding frame 5 for storing seed paddy. Each of the hoppers 4 has a feeding roller 6 axially supported therein, and the seed paddy in the hopper 4 rotates the feeding roller 6. Along with this, a predetermined amount is fed out, and the seeds are dropped from the notch groove (not shown) of the float 7 through the conduit 4a and sown.

Reference numeral 8 denotes a rolling spring, and the seeding portion 3 is configured to be able to roll around a pivot shaft (not shown) provided at the center portion in the width direction so as to follow the unevenness of the rice field. . The power of the sowing section 3 is the PTO of the traveling body 1.
It is introduced from the shaft via the universal joint shaft 9. Reference numeral 10 is a wire-drawing marker which is located in front of the hopper 4 and arranged on both the left and right sides of the seeding section 3. Has been done.
13 is a tension spring, 14 is a wire for raising the marker,
When the seeding section 3 is raised by hydraulic operation during traveling of the machine body, the wire 14 is pulled so that the marker 10 stands up in a non-acting posture against the spring 13 with the pin 12 as a fulcrum.
When the seeding section 3 descends and comes into contact with the rice field, the marker 10 is released from the regulation by the wire 14 by the operation of the marker lever (not shown), and the spring 13 keeps it lying in a substantially horizontal drawing action posture. It is configured. Therefore, the wire-drawing marker 10 draws a fan-shaped up-and-down operation locus about the pin 12.

Reference numeral 15 is a marker receiver mounted on the left and right sides of the seeding section 3 so as to be elastically displaceable corresponding to the drawing markers 10 and 10. The marker receiving member 15 holds the drawing marker 10 in a non-acting posture. Is provided in a state in which the wire drawing marker 10 is projected into the up and down operation path, and the hook portion 15b for fixing the wire drawing marker 10 in the non-operating posture is provided in a state of being retracted from the up and down operation path of the marker 10. Has been.

In this embodiment, the marker receiver 15 is constructed as follows.
That is, the coil spring 16 is formed on the base end side of the wire rod that constitutes the marker receiver 15, one end of the coil spring 16 is extended downward, and the extension 16a is provided outside the outer hopper 4. A push bolt 18 is attached to the pipe-shaped stay 17 which is erected on the seeding frame 5 along the side surface.
While inserting and fixing via, while extending the other end side of the coil spring 16 inward and bending the middle part of the extension 16b to interfere with the up and down operation trajectory of the marker 10. The stopper portion 15a is formed by projecting forward, is then folded back from the projecting end portion to the bending base end portion, is further bent inward from the folding back end portion, and the hook portion 15b is provided at the extending end portion thereof to form the marker 10 It is formed in a state of being retracted rearward from the up-and-down operation locus.

Alternatively, the entire marker receiver 15 may be formed of an elastic wire or plate to fix the base end to the seeding section 3 side.

6 and 7 show a structure in which the present invention is installed in a riding rice transplanter.

19 is a planting section and 20 is a seedling stand. The marker receiver 15 ′ is located on the rear surface side of the seedling placing table 20 and attached to the planting frame 22 via the stay 21. 10 'is a line drawing marker. The structure of the marker receiving member 15 'and the action of the marker receiving member 15' on the line drawing marker 10 'are the same as those of the present embodiment.

In the above configuration, when driving on the road or during the off-season, the left and right line drawing markers 10 are erected, and the markers 10 are slightly moved toward the inside of the fuselage against the elasticity of the marker 10 itself and the elasticity of the spring 13. The hooking marker 10 is fixed to the hook portion 15b of the receiving tool 15 and stored. At that time, if the marker receiver 15 is pulled outward, the marker receiver 15 is elastically displaced by the elastic force of the coil spring 16, and the hook portion 15b is moved to the marker 1.
It can be easily hooked at 0 (see A and D in Fig. 5). When the marker 10 is engaged, the stopper portion 15a can be used as a grip portion, which is convenient.

By the way, at the time of sowing work, the hook portion 15b is removed from the marker 10, the marker receiver 15 is returned to the original state shown in FIG. 5E, and the left and right markers 10 are set as shown in FIGS. 5C and 5F. The work is started in the non-acting posture that is received from the inside by the stopper portion 15a. During sowing, the marker is changed every time the aircraft is turned.
Although one of the 10 (markers on the unseeded land side) is in the working posture (falling posture) and the other (the marker on the already seeded ground side) is in the non-working posture (standing posture), the tilting operation is repeated (seeding section). Three
The marker 10 of the working posture automatically stands up when the
The hook portion 15b of the marker receiver 15 is provided so as to be retracted from the raising / lowering operation locus of the marker 10, and further, the stopper portion 15a for receiving the marker 10 in the non-acting posture is provided on the outer side of the hook portion 15b. Therefore, even if the marker 10 swings due to a reaction or the like during the stand-up operation, the marker 10 is reliably prevented from being caught by the hook portion 15b. Therefore, the inconvenience that the marker 10 suddenly engages with the hook portion 15b when the marker 10 is tilted and the automatic tilting operation is disabled is eliminated, and the wire drawing work by the marker 10 is always performed smoothly and reliably. Be seen. Further, abnormal operation such as overrun due to inertia during marker operation is stopped and blocked while being buffered by the stopper portion 15a, so that mud and the like adhering to the marker 10 is prevented from recoiling and scattering to the aircraft side. . Since the marker receiver 15 is arranged at a relatively high position above the hopper 4 and receives the marker 10 near the tip, the recoil of the tip is small and the effect of preventing the scattering of mud or the like is further enhanced.

Effect of the Invention As described above, according to the present invention, when the drawing marker is stored,
By elastically displacing the marker holder, the marker can be hooked on the hook part and easily fixed in the non-working posture.However, when the marker is used, the marker suddenly catches on the hook part due to vibration due to recoil, etc. In addition to eliminating inconvenience such as inability to overturn, the stopper can prevent abnormal operation such as overrun due to inertia at the time of marker operation, and the wire drawing work with the marker can always be performed smoothly and reliably. , It is possible to eliminate the scattering of mud and the like attached to the markers to the side of the machine body.
