Description

[Detailed description of the invention]

[0001]

[Field of Industrial Application] A tilling rotary, which is supported laterally on a tilling transmission case, is constituted by a plurality of cultivating claw shaft cylinders divided in an axial direction, and of these, a tilling disposed adjacent to the tilling transmission case. The present invention relates to a device for preventing accumulation of soil or the like implemented in a rotary tilling device in which a claw shaft cylinder is rotated in an upcut direction opposite to that of another cultivation claw shaft cylinder.

[0002]

2. Description of the Related Art As shown in FIG. 4, among tilling claws (2) arranged on the right and left portions of a tilling transmission case (1), a tilling claw (2a) arranged close to a tilling transmission case (1) is used. Rotate in the up-cut direction (f1) and rotate other tilling claws (2
As for b), a rotary tilling device of a partial forward / reverse type configured to rotate in the opposite direction (f2) is known (for example, see Japanese Patent Publication No. 46-39041). The tilling claw (2a), which is located close to the tilling transmission case (1) and rotates up-cut, prevents dash phenomena in front of the machine body while processing residual tilling immediately below the tilling transmission case (1). It is designed to rotate around the tilt axis.

[0003]

In a rotary tilling apparatus of this type, a tilling claw (2a) located close to a tilling transmission case (1) plows soil in a direction opposite to a traveling direction of a tilling machine. Since the cutting is performed, there is an extremely strong tendency that the cut soil and grass straw accompanying the cutting soil are pressed and deposited on the lower front part (p) of the tilling transmission case (1). However, when the accumulated soil and the like increase, the soil and the like come into contact with the soil surface during the tilling, and the cultivated portion is lifted, the cultivation becomes shallow, and the resistance to forward movement increases, and the drive wheels ( 4)
, And continuous and smooth tilling work cannot be performed.

[0004] Therefore, means for preventing the cutting soil or grass straw from adhering and accumulating on the tilling transmission case is adopted. As a means for preventing the tilling transmission case, the tilling transmission case is attached to the tilling claw located near the tilling transmission case. An auxiliary claw that protrudes toward the side is integrally provided, and the auxiliary claw is used to scrape off soil and grass (for example, see Japanese Utility Model Publication No. 44-322 and Japanese Utility Model Publication No. 49-29002). However, these conventional ones have an auxiliary nail for scraping off the soil and grass, which is provided integrally with the tilling nail. There is a problem in that handling is troublesome, for example, it is not possible to replace only one, or even if it can be replaced, it takes a lot of trouble.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has a plurality of claw mounting seats disposed on an outer peripheral portion of a tilling claw shaft cylinder adjacent to a tilling transmission case. Either of them, projecting toward the tilling transmission case side, and
A support member provided with a repelling plate inclined in the direction opposite to the up-cut rotation direction toward the tip end is configured to be attached, so that it can be easily attached and detached independently of the tilling claw. Things.

[0006]

[Effects of the Invention] According to the present invention, it is possible to cope with wear of the repelling plate by attaching and detaching the support member regardless of the tilling claw attached to the tilling transmission case while the tilling claw is attached. By replacing it, it is possible to adjust the dash stopping power of the aircraft very easily, while retaining the function of repelling and removing soil and grass straw.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows a main part of a rotary tilling apparatus in which the present invention is implemented. FIG. 1 is a view of the main part viewed from the rear, FIG. X1-X1
It is a figure which shows a part. The tilling rotary supported horizontally on the tilling transmission case (1) is constituted by a plurality of cultivating claw barrels (5), (5), (6), (6) divided in the axial direction.

The cultivating claw barrels (6) and (6) arranged adjacent to the left and right sides of the tilling transmission case (1) have their outer sides in the axial direction inclined at a constant angle lower than the horizontal axis. And is provided so as to rotate up-cut in the traveling direction of the fuselage. Further, the cultivating claw barrels (5) and (5) disposed on the axially outer side of the cultivating claw barrels (6) and (6) are supported horizontally, and are rotated in a down-cut direction in the machine advancing direction. It is provided to be.

[0009] A plurality of claw mounting seats (9) are provided on the outer periphery of the cultivation claw shaft cylinders (6) (6) disposed adjacent to the left and right sides of the cultivation transmission case (1). A cultivating claw (2a) is attached to some of them, and a supporting member (8) separate from the cultivating claw (2a) is attached to the remaining claw mounting seat (9).
The support member (8) is provided with a repelling plate (7) projecting toward the tilling transmission case (1).

When the side edge (7a) of the repelling plate (7) in the direction of the extension extends along the side outer surface of the tilling transmission case (1), the tilling claw shaft cylinders (6) and (6) rotate up-cut. In addition, the side edge (7a) is made to pass as close as possible to the tilling transmission case (1). Further, when viewed from the side, it is bent in a letter shape, and is formed so as to go outward in the radial direction of the rotation trajectory in the direction opposite to the upcut rotation direction. In addition, (2b) shows the tilling claw which is attached to the horizontal cultivating claw shaft cylinder (5) and (5) and which rotates downcut.

[0011] When the rotary tilling apparatus thus configured is operated, the support member (8) mounted on the tilling claw shaft cylinders (6) and (6) located adjacent to the tilling transmission case (1) moves the tilling claw shaft. Up-cut rotation is performed together with the other tilling claws (2a) group in the cylinder (6). Then, the repelling plate (7) of the support member (8) repels and removes soil and grass straw that are to be carried around by the rotation of the tilling claw (2a) by repelling obliquely forward in the traveling direction. (1) Adhesion to the outer surface is prevented.
