Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover device for an apron pivoting portion in various types of rotary working machines used for tilling and shaving, such as rotary and shaving harrows.

[0002]

2. Description of the Related Art Conventionally, a rotary work machine generally used for tilling or plowing is provided with a shield cover for covering an upper portion of a rotor, a harrow, and the like, and an apron is provided near a rear end of the shield cover. Is provided. This apron is for suppressing the tilling surface or leveling the shaving surface, and has an upper end pivotally mounted near the rear end of the shield cover so as to be able to swing back and forth.

[0003]

Since there is a gap between the rear end of the shield cover and the upper end of the apron, soil and mud jumped up by the rotary work machine are removed from the gap. There was a problem that it fell to the outside of the apron and roughened the tilling surface and the plowing surface.

In addition, the jumped-up soil or mud clogs the apron pivot point, and the apron swings heavily, and does not function sufficiently as an apron, or rust occurs at the apron pivot point to cause apron. There was also a problem that premature damage was caused. For this reason, a rubber cover is fixed between the rear end of the shield cover and the upper end of the apron, but in this case, the movement of the apron becomes poor,
There was a problem that the rubber cover was easily damaged.

Therefore, the present invention can prevent soil and mud splashed by the rotary working machine from falling to the outside of the apron or clogging the apron pivot.
An object of the present invention is to provide an apron pivoting portion cover device of a rotary working machine in which the movement of an apron is smooth and damage to a rubber cover is reduced.

[0006]

SUMMARY OF THE INVENTION For this purpose, the present invention provides a rotary working machine in which an upper end of an apron is pivotally mounted near a rear end of a shield cover. A rubber cover covering the inside of the apron is provided so that the front end of the rubber cover is fixed to the rear end of the shield cover, and the rear end is a free end and is in contact with the upper inner surface of the apron. It is characterized by doing.

[0007]

[Function] By adopting such a means, the soil and muddy water jumped up near the upper end of the apron by the rotary working machine hit the rubber cover and fall into the inside of the apron, and the apron moves smoothly. In addition, the rubber cover is hardly damaged.

[0008] Therefore, the cultivated surface or the plowed surface which is suppressed or leveled by the apron is maintained in a good condition without being roughened by soil or muddy water. In addition, the apron does not swing heavily, and exerts its intended function sufficiently to suppress or equalize it.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below with reference to the accompanying drawings. In FIG. 1, reference numeral 1 denotes a shield cover mounted on a substitute harrow as a rotary working machine, and covers an upper portion of a harrow 2 driven to rotate. Reference numeral 3 denotes an apron whose left and right ends in the width direction at the upper end are pivotally attached to a side cover 5 via hinge pins 4 and can swing back and forth.

Here, the upper end of the apron 3 faces near the rear end of the shield cover 1, and a gap 6 is opened between the two. In order to cover the gap 6 from the inside, a horizontally long rubber cover 7 is provided to extend over the rear end of the shield cover 1 and the upper end of the apron 3.

The rubber cover 7 has substantially the same width as the apron 3. Only the upper end of the rubber cover 7 is bolted to the support plate 1a provided inside the rear end of the shield cover 1 via the holding plate 8. -It is fixed with the nut 9. The lower end of the rubber cover 7 in the free state is in contact with the inner surface of the apron 3 because the intermediate portion is supported by the pressing plate 8.

Next, the operation of the embodiment of the present invention configured as described above will be described. In the scraping operation using the scraping halo as a rotary working machine, the halo 2
The muddy water splashed up by the rotation of is prevented from being scattered outward by the shield cover 1, the side cover 5, and the apron 3. In particular, the muddy water that has jumped up near the upper end of the apron 3 flows out of the gap 6 between the rear end of the shield cover 1 and the upper end of the apron 3 or is clogged at the pivotal connection of the apron 3. Without having to
It hits the rubber cover 7 and falls inside the apron 3.

Here, since the lower end of the rubber cover 7 in contact with the inner surface of the apron 3 is in a free state, the apron 3 can freely swing back and forth according to the unevenness of the scraping surface. Therefore, the apron 3 uses its function to smooth out the surface.

As described above, in this embodiment, since muddy water does not flow out of the apron 3 from the gap 6 between the rear end of the shield cover 1 and the upper end of the apron 3, the muddy water is leveled by the apron 3. The scraping surface is kept in a good condition without being roughened by the drop of muddy water.

Further, since the muddy water does not clog the pivotal portion of the apron 3 pivotally attached by the hinge pin 4, the apron 3 does not swing heavily back and forth, and has a good leveling action according to the unevenness of the scraping surface. I do. Moreover, the apron 3 is less likely to be damaged because muddy water prevents rust from being generated at the pivot portion.

Further, since the rubber cover 7 is only in contact with the inner surface of the upper part of the apron 3 with the rear end as a free end, the bending and stretching force when the apron 3 swings does not work strongly, and the apron 3 does not work.
Less damage.

The present invention can be applied not only to the rotary or the shaved harrow but also to various rotary working machines having an apron.

[0018]

According to the present invention, as described above, the soil and muddy water that has been splashed up near the upper end of the apron by the rotary work machine hits the rubber cover and falls inside the apron. Falling,
Alternatively, the apron is prevented from being clogged at the apron pivot, and the movement of the apron is smooth, and the desired function is sufficiently exhibited to suppress or equalize. Also, since the rubber cover is only in contact with the inner surface of the upper part of the apron with the rear end as a free end, the bending and stretching action due to the apron swinging does not work strongly, and the rubber cover is more damaged than the one with the rear end fixed to the upper part of the apron. It becomes difficult.
