Description

  The present invention relates to a riding grooving machine that forms a deep groove using the weight of an operator in order to quickly supply and drain water to a paddy field.

  Conventionally, grooving work has been carried out for the purpose of quickly supplying and draining water to paddy fields to improve the growth of crops. The conventional grooving machine walks while following the grooving machine, and forms a groove by being pulled by the driving wheel while the operator presses the triangular plate provided behind the driving wheel against the ground. Grooving machines are becoming mainstream. Further, a grooving machine in which a grooving plate is attached to the rear of a 4-wheel paddy management machine represented by a riding rice transplanter and the groove is formed while pressing the grooving plate against the ground is already known.

  In addition, even if the applicant of this patent is as light and portable as a walking grooving machine, the occupant rides a grooving machine that forms a deep groove using the weight of the operator. On August 29, 2003, a patent application was filed as Japanese Patent Application No. 2003-306008 (Japanese Patent Laid-Open No. 2005-73540).

Japanese Patent Laid-Open No. 2005-73540

  Grooving using a four-wheeled paddy paddy machine is an easy task for the operator. However, the stepping of rice during turning and the joining of grooves to each other are not performed properly. It has not yet spread due to problems such as breaking the cage when entering and leaving, and the cost of the machine itself.

  Therefore, the applicant of the present patent application is light as a walking follow-up type grooving machine, and enables the operator to board (strip or sit on) the grooving machine even if the cost is low. A grooving device capable of forming a deep groove by utilizing weight is proposed as in Patent Document 1.

  In the embodiment of Patent Document 1, a driving part is provided at the front and a grooved part is provided at the rear, and a riding part is provided at a substantially upper intermediate position between the driving part and the grooved part, so that an operator can straddle or sit on the board.

  The grooving machine 1 shown in FIG. 3 has a structure in which the holding member 21 including the grip 22 of the riding section 4 can be separated from the seat surface 20. A part of the holding member 21 is inserted into the bottom of the seating surface 20 and can be fixed with the fixing screw 19. In FIG. 3, the two holding screws 19 are used to fix the holding member 21 to the bottom surface of the seating surface 20. However, the number of the fixing screws 19 may be a plurality of four or considering the workability, the fixing screws 19 may be used. If 19 is one, workability can be improved.

  In the first embodiment, the height of the riding section 4 on which the worker 8 rides can be adjusted up and down. In the second embodiment, the position of the holding member 21 when the worker 8 gets on the seating surface 20 of the riding section 4. The structure which can adjust to the front-back direction toward the advancing direction is proposed. Therefore, in the embodiment of the present invention, either the height adjustment mechanism of the riding section 4 on which the worker 8 rides, or the mechanism in which the worker 8 can move the holding member 21 for holding the grooving machine 1 in the front-rear direction. Or it has a mechanism of both.

  2, the plurality of holes provided in the vertical direction of the frame 10 and the frame 6 are shifted in the vertical direction, and are fixed with fixing screws 17 at the positions where the respective holes are provided. Although the height is adjusted, one or both of the frame 10 and the frame 6 are provided with several holes in the front-rear direction with respect to the traveling direction 23, and the entire riding section 4 is slightly front-rear with respect to the traveling direction. It is good to be able to attach it in the direction (not shown).

  The operator 8 grasps both sides of the grip 22 provided at the upper end of the holding member 21 of the riding part 4 with each hand, and then straddles or sits down on the seating surface 20, and takes the riding part 4 to his working posture. It is confirmed whether there is a height or a position of the grip 22 in the front-rear direction.

  When the height of the riding section 4 is different from the orientation of the operator 8, the fixing screw 17 is loosened, the frame 6 and the frame 10 of the riding section 4 are separated and shifted up and down, and the scattered holes are aligned with each other. The height is set to a position desired by the operator 8, and the frame 6 and the frame 10 are coupled again with the fixing screw 17.

  Further, when the operator 8 gets on the riding part 4 and grips the grip 22 provided on the holding member 21, if the operator 8 is different from the orientation of the operator 8, the fixing screw 19 is loosened from the bottom surface of the seat surface 20. The holding member 21 is inserted and removed or separated, moved to a position where the operator can easily hold the grip 22 in the front-rear direction, and fixed again by the fixing screw 19 so that the holding member 21 does not move back and forth from the bottom of the seating surface 20. Is.

  When each position is determined, the operator 8 operates the rotation adjusting device 26 provided on the grip 22 to transmit the power of the engine 11 to the gear box 13 via the power transmission shaft 12 to rotate the wheel 14. Then, the grooving operation is performed in the traveling direction 23.

  When forming a groove using the grooving machine 1, the operator 8 gets on the riding part 4, throws out both feet toward the front in the traveling direction 23, and at the same time the machine advances. The foot of the foot of the foot is slightly touched to the ground and the balance is progressed while sliding the foot of the foot, but the height of the seat 20 is adjusted according to the height, physique and weight of the worker 8 and their respective orientations. If you do not work, it will be difficult to work. In addition, the grip 22 that was easy to hold in the stationary position also needs to bring the center of gravity of the worker 8 to a place different from the stationary position, depending on the hardness of the field or the weight of the worker 8. It is necessary to fix the position.

  By starting the grooving operation, the posture position that was good at the stationary position is also forced to change, so that the worker 8 is considerably displaced from the position of the height of the seating surface 20 at the time of the operation, If it is determined that the seat surface 20 itself should be moved in the front-rear direction with respect to the traveling direction, the fixing screw 17 is loosened and the height and the position of the seat surface in the front-rear direction are adjusted. The holding member 21 also has a distance from the seating surface 20 of the holding member 21 at a position where the operator can easily hold the grip 22 in a place where the center of gravity of the worker 8 seems to be relatively centered during the work. Adjust again.

  When the worker 8 is different, when the farm field is moved and the hardness of the farm field and the depth of the cultivator are different, the worker 8 moves the front and rear and the height position of the seating surface 20 of the riding section 4 on which the worker 8 rides. 1 so that the distance from the holding member 21 and the seating surface 20 for the operator 8 to hold 1 can be moved to a position where the operator 8 can easily work according to the orientation of the operator 8, the depth of the groove, and the traveling speed. The work can be performed comfortably.

  Conventionally, it is well known that grooving operations in paddy fields can be carried out systematically in irrigating and falling water of paddy fields, so that the growth of rice roots is promoted and a strong and high yielding rice that does not fall down is known. However, grooving work is a heavy labor performed during high-temperature and high-humidity periods, and is difficult to incorporate with current farming methods that seek low cost and low labor.

  Therefore, in the present invention, even if it is a riding type, it is lightweight and can be easily carried, and a grooving machine that can easily create a deep groove by using the weight of the worker is further adapted to the worker's physique and body shape. Adjusting the height of the seating surface of the board and holding the grooving machine body, the grip held by the worker can be moved in the front-rear direction according to the weight of the worker and the hardness of the field to be grooved Therefore, it becomes possible to provide the operation position of the grooving work suitable for the worker, and the worker can easily perform the grooving work and can reduce labor.

  The widespread use of grooving work promotes the growth of rice roots and leads to the production of strong, high-yielding rice without lodging, thus promoting the improvement of the taste and quality of the whole rice and improving the basic physical strength of Japanese agriculture. I think there is.
