Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a leveling level of a scraping device which is an operation before rice transplanting in a paddy field or before sowing rice seeds.

[0002]

2. Description of the Related Art Conventionally, with regard to this kind of leveling leveling section,
JP-A-6-165605 is known. This conventionally known scraping device includes a machine frame, a rotary work body rotatably provided on the machine frame, and a first leveling ground supported at the rear of the rotary work body and supported vertically. And a second terrain body that is supported at the rear of the first terrain body and that is vertically movable. The rear end of the first terrain body and the second terrain A guide plate that is inclined forward and downward from the front end of the body and drains muddy water at the time of leveling through the second leveling body behind the second leveling body with the guide plate. A plurality of guides, each having a drain port formed therein, facing the inflow portion of the drain port on the first terrain body, and guiding contaminants flowing into the inflow section toward the second lower terrain body at the rear lower side. The rods are juxtaposed at intervals and are projected downward from the front of the leveling plate of the second leveling body. The number of induction bars to embed inclined to protrude been contaminants toward the rear downward from the leveling plate in the ground is obtained by parallel at intervals.

[0003]

According to the above-mentioned prior art, together with the fine soil action, mud is passed through the guide plate from the rear end portion of the first leveling body, passes through the upper surface of the second leveling plate, and moves backward. However, there is a disadvantage that the total length of the first terrain and the second terrain is long and the second terrain is heavy.
In addition, a number of guide rods for guiding toward the second terrain body are juxtaposed to bury the foreign matters. The mud will simply run off the mud surface further and separate and will not mix. Therefore, there is a problem that the muddy water separated on the surface becomes resistant to the penetration of the seed into the soil particularly in the direct sowing operation of the seed.

[0004]

In order to solve the above-mentioned problems, a scratching device comprising a crushed portion, an upper cover covering the crushed portion, and a leveler swingably connected to a rear edge of the upper cover. Further, the present invention provides a scratching device characterized in that a partition rake formed by arranging plate materials in a comb-like shape with front and rear sides provided between a leveler and the rear of the crushed soil portion is provided. Further, in the above-mentioned scraping device, the lower end of the partition rake is formed so as to be located further below the contact surface of the leveler.

[0005]

The comb-like plate forming the partition rake provided between the leveling device and the rear side of the scraping device embodying the present invention partitions the muddy water on the surface of the scratching surface in the left-right direction and has a U-shape in plan view. By forming a large number of partition rooms, muddy water is forced into the inside of the soot again and mixed. or,
Since the plate members are arranged in a comb shape in the front-rear direction, and are located further below the ground contact surface of the leveler, the solidified solid mass is guided into the substitute soil while being crushed, and the surface is leveled.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration will be described with reference to the drawings embodying the present invention. FIG. 1 is a side sectional view embodying the present invention, and FIG. 2 is a perspective view showing a main part. Reference numeral 1 shown in FIG. 1 denotes a top hitch, which is provided at the top of the mission 3. The input shaft 2 is disposed in front of the mission 3 and the pipe frame 4 is provided so as to project toward both sides. A transmission shaft 5 is mounted on one side of the pipe frame 4 and supports a wide and wide crushed soil portion 8 at both ends. Reference numeral 7 denotes an upper cover having an arc-shaped cross section that covers the upper portion of the crushed soil portion 8.

Reference numeral 14 denotes a first leveler, the front end of which is swingably fixed to the rear end of the upper cover 7 by a first pin 18. A second leveler 17 is rotatably fixed to the rear end of the second leveler 14. Reference numeral 17 denotes a second leveler, the front end of which is a second pin 19.
Accordingly, the first leveler 14 is rotatably fixed to the rear end of the first leveler 14. Reference numeral 16 denotes a first tine, which is attached in parallel from the rear end of the first leveler 14 toward the ground. 17 is a second tine, the second leveler 15
And is arranged in parallel along the bottom plate of the second leveler 15.

Reference numeral 10 denotes a fixed switching case, which has a cam mechanism for locking the support link 11 downward and opening it upward.

Reference numeral 12 denotes an auxiliary rod fixed to the other end of the support link 11, and the lower end of the auxiliary rod 12 is
It is connected to the upper surface of the leveler 15. An operation lever 20 provided above the top hitch 1 is interlocked with the fixed switching case 10 to control the support link 11 so that the second leveler 15 can swing freely and stand upright via the auxiliary rod 12. To have a fixed action.

Reference numeral 13 denotes a partition rake. In the present embodiment, a plurality of thin plate members 25 are arranged side by side in the lateral direction, and the upper end thereof is fixed to a transfer bracket 26. The thin plate member 25 hangs down in parallel in the front-rear direction, is curved downward in a side view, and has a lower end located further below the ground surface of the second leveler 15. In the present embodiment, the transfer fitting 26 is an angle material and the upper surface is fixed over the entire width of the rear edge of the upper cover 7 described above.

Therefore, the claw 9 for plowing and crushing the soil is normal rotation (arrow).
As it rotates, the earth mass is crushed by the partition rake 13 which is close to the rear part of the rotation locus and is mixed into the soil. And the crushed soil are further fused. The mud that has been fused and sent is the first leveler 14
And rough impurities are buried in the mud layer by the first tine. Further, while the surface is finished evenly by the second leveler 15, the impurities left on the surface are buried in the soil by the second tine 17.

Referring to FIG. A side case 21 is provided at a side end of the pipe frame 4 to transmit the power transmitted by the transmission shaft 5 to the rotating shaft 6 to rotate the crushed soil portion 8. In the partitioning rake 13, a transfer bracket 26 is fastened with a bolt and a nut to a portion where the rear edge of the upper cover 7 is horizontally folded rearward. The first leveler 14 is provided with a coil spring 24 provided on a rod 23 and supported by an arm 22, and is installed by being pressed downward.

[0013]

According to the above construction, the muddy water is mixed with the mud while preventing the muddy water from colliding with the leveler and flowing to the right and left during the scraping work, and is uniformly formed in the mud soil. Is done. Therefore, it is suitable for high-speed work and direct sowing work in which seeds are directly driven.
