[Structure] In a passenger rice transplanter configured by connecting a planting part B in which at least the rearward portions of both rear wheels 1 of this machine A are floatless to the rear of this machine A, the rear of both rear wheels 1 Is constructed by erectioning a pair of both mark erasing bodies 3a, 3b which are symmetrical in shape and face each other horizontally so that the bottom surface 2 is horizontal and the mark erasing can be performed from above both sides of the wheel mark. In addition, both the mark erasing bodies 3a and 3b are formed in a triangular pyramid shape in which the respective inner side surfaces 4 facing each other are parallel to each other and parallel to each other, and the front surface 5 is a vertical triangular surface. It is composed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wheel erasing device for a riding rice transplanter capable of effectively erasing the wheels behind the machine, which pulls at least the planting part where the rear sides of both rear wheels of the machine are floatless. .

[0002]

[Prior Art]

 Conventionally, in order to further increase the speed of a rice transplanter, it is known that at least the portion behind the rear wheels of the machine is floatless below the planting section towed by the machine. .

[0003]

[Problems to be solved by the device]

 However, as described above, in the passenger rice transplanter configured by connecting the planting part in which at least the rear parts of the rear wheels of the machine are at the rear side of the machine to the rear of the machine, both rear wheels of the machine are There are defects such as wheel marks left behind and unevenness on the surface of the field, resulting in poor precision of seeding and easy growth of weeds.

[0004]

[Means for Solving the Problems]

 The present invention has been devised so as to solve such a problem and effectively eliminate the marks on the wheels and level the wheels.Therefore, in the rear of both rear wheels, symmetrical shapes are provided on the left and right sides. In addition, the bottom surface is horizontal and a pair of both mark erasing bodies capable of erasing the mark from both sides of the wheel mark are erected, respectively. The inner side surfaces are vertically parallel to each other and the front surface is a vertically triangular surface, forming a triangular pyramid.

[0005]

[Action]

 Therefore, in the running traces of both rear wheels, a groove is formed above both sides to allow the soil to rise, but the mark erasing bodies on both sides where the bottom surface is horizontal move forward across the groove while It is possible to backfill the soil that rises in the ditch into the ditch, and level the surface with a horizontal bottom surface. Also, by forming a double-sided eraser in the shape of a triangular pyramid, while leveling the soil surface with the horizontal bottom surface, Water can flow smoothly backwards.

【Example】

 1 to FIG. 11, FIG. 1 is a side view of a riding rice transplanter, in which a link mechanism 9 is installed behind the machine A equipped with both front wheels 6, both rear wheels 1, a handle 7, a seat 8 and the like. The attachment part B is configured to be movable up and down, and the planting part B has a center float 10 only at the lower center part, and a floatless above the center float 10 and behind both rear wheels 1 of the machine A. Three planting cases 11 are erected above the area to be the above, and the rear part of each planting case 11 is equipped with double-type planting claws 12, respectively. Above the seedling take-out plate 13 which is horizontally installed across, the seedling mounting table 14 which reciprocates in the lateral direction is installed obliquely.

Both ends of a support frame plate 16 which is horizontally mounted via a bracket 15 above the front part of the center float 10 are extended to the rear of both rear wheels 1 of the machine A, and the support thereof is supported. Below the both ends of the frame plate 16, a pair of four plates made of symmetrical flat plates are vertically erected so as to face left and right, the bottom surface 2 is horizontal, and the marks can be erased from above both sides of the wheel mark. The square-shaped mark erasing bodies 3a, 3b are hung vertically, but the upper portions of both support shafts 17a, 17b fixed to the lateral outer surfaces of the center of the mark erasing bodies 3a, 3b are made rotatable to the support frame 16. Fan gears 18a and 18b, which mesh with each other, are fixed to the upper portions of both the support shafts 17a and 17b on the support frame 16, respectively. The arm 19 extending to the In addition to connecting 0, the operation wire 21 that can be operated from the side of the machine A is connected so that both mark erasing bodies 3a and 3b can be rotated in opposite directions about the support shafts 17a and 17b. The bottom surfaces 2 of the mark erasers 3a and 3b and the bottom surface of the center float 10 are arranged on the same horizontal plane.

Therefore, as shown in FIG. 10, the running marks of both rear wheels 1 are formed with grooves on the upper side of both sides to raise the soil, but the mark erasing bodies 3 on both sides where the bottom surface 2 becomes horizontal. While a and 3b move forward across the groove as shown in FIG. 11, it is possible to backfill the groove with soil rising up on both sides of the groove, and level the surface with the horizontal bottom surface 2. Further, it is possible to operate the operation wire 21 from the side of the main body A to rotate both the mark erasing bodies 3a and 3b. In a weakly viscous field, as shown in FIG. Shape, or in a highly viscous field, as shown in Fig. 8, to adjust by adjusting the shape of a flat inverted C with a sloping slope, or when water is accumulated, as shown in Fig. 9. Adjusting it parallel to the horizontal prevents horizontal vibration and causes floating seedlings. It can be prevented from growing.

FIG. 12 to FIG. 14 show another embodiment. In both of the mark erasing bodies 3a and 3b, the inner side surfaces 4 facing each other stand upright in a triangular surface to be parallel surfaces to each other and the front surface 5 to each other. It is formed in the shape of a triangular pyramid, which is a vertical triangular surface, and is connected by an upper connecting metal fitting 22 and can be supported by a supporting rod 23. As shown in FIG. When the water is accumulated, the horizontal bottom surface 2 makes the soil surface even, while the water flows smoothly between the mark erasers 3a and 3b and above, as shown by the arrows in FIG.

[0010]

[Effect of the device]

 In this way, according to the present invention, the running marks of both rear wheels 1 are formed with grooves on both sides above which soil is raised, but the mark erasing bodies 3a and 3b on both sides where the bottom surface 2 is horizontal. As the soil moves forward across the ditch, it fills the ditch with soil that rises up on both sides of the ditch, and evens out the surface with the horizontal bottom surface 2. If it is formed in a flat shape, the horizontal bottom surface 2 will make the soil surface even, while allowing water to flow smoothly to the rear, so that the planting section B of the floatless plant can be planted with high precision. It has the advantage that it can be suitably implemented because it can effectively erase the marks.
