Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is designed to prevent foreign matters such as waste straw and leaves scattered in a field from being scattered by the rotation of a vertical cutting blade, and the foreign matters to be reversed. Plowing that prevents foreign matter from being exposed to the surface of a completed gravel (hereinafter referred to as "reversal gravel") or falling onto the surface of a gravel that is in the process of being inverted, thereby preventing foreign matter from being exposed between adjacent reciprocal gravel. The present invention relates to a reversing work machine.

[Conventional technology]

FIG. 8 to FIG. 10 show a conventional triple-type tillage reversing work machine.

A plurality of beams B _{1 to} B ₄ are attached to the machine body 2 at predetermined intervals along a direction perpendicular to the traveling direction P of the machine body 2. A horizontal cutting blade 4, a reversal earth plate 6, a foot wipe earth plate 8 and a holding plate 10 are attached to the central beams B ₂ and B ₃ , respectively.

The beam B ₄ at the end portion in the reversal direction Q of the gravel is provided with only the foot-dispersing earth plate 8, and the reversal direction Q of the gravel is
A horizontal cutting blade 4, a flipping earth plate 6, and a holding plate 10 are attached to the beam B ₁ at the end portion in the opposite direction.

In front of each beam B ₁ .about.B ₄ is attached a horizontal rotary shaft 12,
Vertical cutting blades 14 and 16 are attached to the horizontal rotary shaft 12.

This tillage reversing work machine is mounted on a tractor (not shown) through a mast 18 and towed, and the power of the tractor is input to an input shaft 20 so that the horizontal rotary shaft 12 rotates. .

A vertical cutting blade 14 attached to the horizontal rotary shaft 12 is for forming a vertical cutting groove 24 for making a rubble 22 in soil. Similarly, the vertical cutting blade 16 is for removing one corner 22a in order to facilitate the reversal of the rubble 22 (see FIG. 4 (a)).

A flat plate-like cover 26 is attached to the machine body 2 so as to cover the rear portions of the vertical cutting blades 14 and 16. The cover 26 is for colliding and dropping scattered materials such as a lump of earth scattered by the rotation of the vertical cutting blades 14 and 16.

When performing the tillage reversal work in a field where a large amount of contaminants such as waste straw and leaves are scattered, rotation of the vertical cutting blades 14 and 16 scatters the contaminants along with the soil block,
It collides with 26 and falls.

However, since the cover 26 has a flat plate shape and the cross-sectional shape is the same in all parts, the position of the foreign matter colliding with the cover 26 is in the lateral direction (direction perpendicular to the traveling direction of the machine body). Is not regulated at all. For this reason, the foreign substances that have collided with the cover 26 fall on the surface of the inverted gravel or drop on the surface of the gravel during the inversion, and are exposed from the overlapping portions of the adjacent inverted gravel.

The impurities embedded in the lower layer of the inverted gravel ripen and are returned to the soil to improve soil fertility, but the contaminants that have fallen to the surface of the inverted gravel do not ripen, and when this contaminant is long , When cultivating with the rear working machine or during tillage work,
Contaminants may wind around the rotating shaft and claws of the work machine, and interfere with these operations.

[Problems to be solved by the device]

According to the present invention, foreign matters such as waste straw and leaves scattered in the field are scattered by the rotation of the vertical cutting blade and collide with the cover, and thereafter, the foreign matters fall on the surface of the inverted gravel,
Alternatively, it is an object of the present invention to prevent the foreign matters from falling on the surface of the gravel during the inversion and exposing the contaminants between the adjacent gravel.

[Means for Solving the Problems]

The present invention is designed to cover a vertical cutting blade for vertically cutting soil into a predetermined width to make a gravel, a flipping earth plate for inverting the gravel, and a rear portion of the vertical cutting blade. In a tillage reversing work machine equipped with a cover attached to a machine body, a partition plate is substantially vertical to a portion below the cover and substantially corresponding to a mounting position of the reversing earth plate, and its rear end is It is characterized in that the portion is attached to be inclined with respect to the traveling direction of the machine body by displacing the portion with respect to the front end portion in the reverse direction of the gravel.

[Function of device]

The partition plate is almost vertical to the portion corresponding to the mounting position of the flipping earth plate below the cover attached to the fuselage so as to cover the rear portion of the vertical cutting blade, and the rear end is Since it is attached to the front end part in an inversion direction of the gravel and inclined with respect to the traveling direction of the aircraft, the soil of the part that was the ground surface of the gravel at the time of inversion and the partition plate, The position along the reversal direction of the gravel corresponds (the partition plate is always located above the ground surface of the gravel during the reversal).

Therefore, the foreign matter that collided with the partition plate falls on the surface of the gravel during the reversal, and as the reversal angle increases, the foreign matter that falls on the surface of the gravel slides down below the gravel and becomes the inverted gravel. Embedded in the lower layer.

〔Example〕

1 to 3 show an embodiment of the present invention, in which the same parts as those described in the above-mentioned "Prior Art" are designated by the same reference numerals to avoid redundant description. Only the characteristic parts of the present invention will be described in detail.

Between the beams B _{1 to} B ₄ of the machine body 2, independent covers 28 are attached so as to cover the rear portions of the vertical cutting blades 14 and 16. A partition plate 30 is attached almost vertically to the end of each cover 28 opposite to the reverse side of the rubble.

As shown in FIG. 2, the partition plate 30 is attached to a portion substantially corresponding to the attachment position of the flipping earth plate 6 in plan view. The rear end of the partition plate 30 is displaced in the reversal direction Q of the soil with respect to the front end, whereby the partition plate 30 is inclined with respect to the traveling direction P of the machine body 2 and the cover 28 is moved.
Is installed below.

When performing the tillage reversal work in the field where the foreign matters A are scattered, as shown in FIG. 4, when the machine body 2 advances, the vertical cutting blades 14 form the vertical grooves 24 in the soil, and at the same time, The horizontal cutting blade 4 horizontally cuts a predetermined depth portion of the soil to form a soil gravel 22 (Fig. 4 (a)). In addition, when the soil gravel 22 is formed, one corner portion 22a of the soil gravel 22 is provided to facilitate the inversion of the soil gravel 22.
Is cut by the vertical cutting blade 16.

The soil gravel 22 formed by the vertical cutting blade 14 and the horizontal cutting blade 4 is gradually inverted by the reversing earth plate 6.
The partition plate 30 is attached to a portion substantially corresponding to the attachment position of the flipping earth plate 6 in a plan view, and its rear end is displaced in the inversion direction Q of the soil rub 22 with respect to the front end. .

Therefore, when the foreign matter A scattered by the rotation of the vertical cutting blades 14 and 16 collides with the partition plate 30, the foreign matter A falls to the portion 22b which was the ground surface of the rubble 22 during the inversion,
As the reversal angle of the rubble 22 increases, the foreign matter A that has dropped onto the portion 22b that was the ground surface of the rubble 22 slides down below the rubble 22 [Fig. 4 (b), (c)]. ].

When the soil gravel 22 is inverted up to about 90 ° by the reversing soil clay plate 6, the lower end of the soil gravel 22 in the middle of reversing is foot-disposed by the foot soil soil clay plate 8 and further about 50 °. Most of the foreign matter A that has been turned upside down and that has fallen to the portion 22b that was the ground surface of the rubble 22 is buried in the lower layer of the turned up rubble [Fig. 4 (d), (e)]. ]. It should be noted that the retaining plate 10 presses the soil gravel 22 that is being inverted from above, so that the soil gravel 22 is reliably inverted.

Further, as shown in FIGS. 5 and 6, a plurality of partition plates 30 are attached to the lower side of one flat plate-shaped cover 26 as described above, and the cover 26 is spread over the entire width via the hinge 32. You may be able to open it.

Further, each of the above-described embodiments is a multiple-type plowing reversing work machine, and is a working machine that performs plowing reversal at the same phase position along the traveling direction P of the machine body 2. As shown in FIG.
In the case of a working machine configured to reverse the plowing at positions displaced along the traveling direction P, the cover 28 having the partition plate 30 may be attached to each part.

[Effect of device]

According to the present invention, the partition plate is made substantially vertical to the portion below the cover attached to the fuselage to substantially correspond to the mounting position of the flipping earth plate in order to collide and drop the scattered matter due to the rotation of the vertical cutting blade. In addition, since the rear end of the gravel is installed inclining with respect to the traveling direction of the aircraft by displacing the rear end in the reverse direction of the gravel above The partition plate is always located at.

Therefore, the foreign matter that collided with the partition plate falls on the surface of the gravel during the reversal, and as the reversal angle increases, the foreign matter that falls on the surface of the gravel slides down below the gravel and becomes the inverted gravel. Embedded in the lower layer. Therefore, the contaminants are not exposed on the surface of the inverted gravel, or the contaminants are not exposed from the overlapping portions of the adjacent inverted graves, or less.
