DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of an embodiment of the agricultural working machine according to the present invention will be described below with reference to the drawings.

In FIG. 2, reference numeral 1 denotes an agricultural working machine such as a rotary. The agricultural working machine 1 is detachably mounted on a tractor (not shown), and travels in a traveling direction X on a field by traveling of the tractor.
Tilling and leveling work while moving toward.

The agricultural working machine 1 includes a machine frame 2.
Has a three-point connecting portion 5 as a tractor connecting portion composed of a top mast 3, a lower arm 4, and the like. A mechanism (three-point hitch) is connected. A PTO shaft of a tractor is connected to an input shaft 6 protruding forward from the machine casing 2 via a universal joint or the like.

The machine frame 2 is provided with a main frame 8 having a longitudinal direction in the left-right horizontal direction which is a direction intersecting the traveling direction X.
The upper ends of a pair of left and right side plate frames (for example, a chain case and a bracket) 9 are fixed to both ends of the main frame 8 in the longitudinal direction.

A rotary work body 11 is rotatably provided between the lower ends of the pair of left and right side plate frames 9, 9 as a soil work body for performing plowing and crushing work by rotation. This rotary work body 11 has a left and right horizontal tillage shaft 12 that is driven and rotated by receiving a driving force from the input shaft 6 side,
A plurality of substantially arc-shaped tilling claws 13 are radially fixed to the tilling shaft 12.

At a position above the rotary work body 11, a cover plate 15 as a plate-like cover body for preventing scattering of soil upward is horizontally fixed to the machine frame 2, and is located.
At the rear end of the cover plate 15, an upper end, which is the front end of a leveling plate 17 as a plate-shaped leveling body for leveling work via a connecting portion 16 composed of a plurality of hinges or the like, is supported in the horizontal direction. Axis 18
The ground adjustment plate 17 is positioned at the rear position of the rotary work body 11 so as to be rotatable so that the lower end thereof can be moved up and down about a support shaft 18 on the upper end side.

Here, as shown in FIG. 1, the cover plate 15 is integrally formed of only one rust-preventive plate material, for example, a stainless steel plate 21 having a smooth surface. This stainless steel plate
Numeral 21 has an elongated rectangular shape curved in a substantially arc-shaped cross section with its center in the front-rear direction bulging upward so as to be located along the movement locus of the tip of the tilling claw 13 of the rotary work body 11. By folding the front edge portion 21a of the stainless steel plate 21 inward so as to have the space portion 22, a two-plate portion 23 having a strength greater than that of the other single portion is formed at the front end of the cover plate 15. ing.

Further, as shown in FIG.
It is integrally formed of only one rust-preventive plate material, for example, a stainless steel plate 26 having a smooth surface. This stainless steel plate 26
It has a bent elongated rectangular shape that is slightly bent along the left and right horizontal directions in different directions at two intermediate points in the vertical direction.

The upper end portion 26a, which is the front end portion of the stainless steel plate 26, is folded outward so as to have a space 27, so that a cylindrical shaft insertion portion 28 is formed at the upper end of the leveling plate 17. The support shaft 18 is inserted into the shaft insertion portion 28. Further, the lower end edge portion 26b, which is the rear end edge portion of the stainless steel plate 26, is folded outward so as to have the space portion 29, so that the lower end portion of the leveling plate 17 has higher strength than the other single sheet portion. A sheet-like plate portion 30 is formed.
The two-plate portion 30 touches the soil by touching the field scene and presses the soil to level the field scene. As shown in FIG. 2, the ground pressure of the two-plate portion 30 is controlled by a ground pressure adjusting means composed of a mounting piece 31 fixed to the ground plate 17 and a rod 33 to which a coil spring 32 is mounted. It can be adjusted appropriately at 35.

Next, the operation of the agricultural working machine 1 according to the embodiment will be described.

When the rotary work body 11 rotates in response to the driving force from the tractor side when the tractor moves in the traveling direction X by traveling of the tractor (not shown), the soil in the field is plowed and crushed. Then, the plowed and crushed soil is leveled flat by a leveling plate 17 located behind the rotary work body 11.
In addition, the soil facing upward from the rotary work body 11 is covered with a cover plate.
Splashing upwards at 15 is prevented.

According to the agricultural working machine 1 of the embodiment, since both the cover plate 15 and the ground leveling plate 17 are formed by using only one stainless steel plate 21 and 26, respectively, Not only the appearance is good based on the gloss of the surface, but also the work of fixing and welding the stainless steel plate to the base plate with fixing tools such as bolts, which was required in the past, is not necessary, making assembly work extremely easy and configuration It is also simple and can be reliably manufactured at low cost. It is not necessary to apply a rust preventive paint to the cover plate 15 and the leveling plate 17.

Further, the lower surface of the cover plate 15 facing the rotary work body 11 is not rusted, and the frictional resistance is not increased. The front surface, which is the opposite surface to the rotary work body 11, is not rusted, and the frictional resistance is increased, and there is no trouble that the soil adheres and grows. Therefore, the work efficiency is improved and the stable tilling work is reliably performed. be able to.

Further, the two plate portions 23 of the cover plate 15 are not inadvertently deformed, and the scattering prevention by the cover plate 15 can be appropriately maintained. Further, the two-plate portion 30 of the grading plate 17 is not inadvertently deformed, and the grading work by the grading plate 17 can be appropriately maintained.

In the above embodiment, both the cover plate 15 and the ground leveling plate 17 are made of one stainless steel plate 21,
Although the configuration using only 26 has been described, for example, although not shown, a configuration in which one of the cover plate 15 and the ground leveling plate 17 is formed using only one stainless steel plate may be used.

In each of the above embodiments, the stainless steel plates 21 and 26 having a smooth surface are used as the rust preventive plate.
Although the configuration using is described, for example, a configuration using a non-ferrous metal plate such as an aluminum plate, a copper plate, a titanium plate, or a non-metal plate such as a resin plate or a ceramic plate as a rust prevention plate material may be used.

Further, a two-plate portion at the front end of the cover plate 15
23, the two plate portions 30 at the rear end of the leveling plate 17 are not necessarily required.

[0032]

According to the first aspect of the present invention, since at least one of the cover body and the leveling body is formed of only one rust preventive plate, the assembling work is easy and the manufacturing can be performed at low cost. In addition, the problem that the soil adheres to the rusted portion and grows hardly occurs.

According to the second aspect of the present invention, the two plate portions of the cover body are not inadvertently deformed, and the scattering prevention by the cover body can be appropriately maintained.

[0034] According to the third aspect of the present invention, the ground preparation body 2
The sheet-like plate portion is not inadvertently deformed, and the leveling workability of the leveling body can be appropriately maintained.

According to the fourth aspect of the present invention, by using a stainless steel plate having a smooth surface, rust can be reliably prevented, adhesion of soil can be effectively prevented, and the appearance is good.
