タリにおけるリヤカバーに関するものである。[Detailed Description of the Invention] The present invention is a forward/reverse rotary rotary machine which is configured so that the direction of rotation of the tiller can be switched between forward and reverse, down cut and up cut, by changing the connection direction of the rotary part to the tractor back and forth. This invention relates to a rear cover in a switchable rotary.

インカバーの後縁とリヤカバーの前縁との間に間
隙が必要である。 The rear cover, whose trailing edge slides against the cultivated soil surface, swings up and down relative to the main cover fixed to the rotary body, so the main cover near the hinge that connects the rear cover to the main cover A gap is required between the rear edge of the cover and the front edge of the rear cover.

る。 When the soil dug up by the rotating plowing body is thrown away, it may blow outward from this gap, or pebbles may become stuck in the gap, preventing the rear cover from swinging smoothly. There is a problem, especially in the case of a rotary machine that can be switched between forward and reverse rotations, since the direction of rotation of the tiller is changed, it is difficult to prevent soil from entering the gap.

て間隙が塞がれるように工夫したものである。 Therefore, in this invention, the front edge of the rear cover is positioned lower than one edge of the main cover when cutting down, and the front edge of the rear cover is positioned higher than the other edge of the main cover when cutting up. As such, the front edge of the rear cover, which forms the front and rear edges of the rotary cover, is located on the front side in the rotational direction with respect to the tilling claw when cutting down, and when cutting up, the front edge of the rear cover is positioned so as to close the gap. The gap is designed to be closed by the edge of the main cover that is on the front side in the rotational direction with respect to the tilling claws.

部Ｂは縁部Ａよりも短かく形成している。 In order to connect the rotary part 10 and the mounting frame part 16, the mounting body 1 of the mounting frame part 16 is
The inverted U-shaped fitting parts 12a, 12a of 2, 12 are fitted onto the pipe frames 4, 5 of the rotary part 10, and the upper surfaces of the pins 23, 23 inserted into the pin holes 12b of the fitting parts 12a, 12a are fitted. It is sufficient if the pipe frames 4 and 5 are brought into close contact with each other, and as shown in FIG.
If the fitting parts 12a, 12a are externally fitted to the pipe frames 4, 5 so as to match the direction in which the mast 24 protrudes, the tiller 9 will turn counterclockwise as indicated by the arrow with respect to the rotary 1 moving leftward. When the rotation is normal, that is, the rotary 1 moves to the left, the rotary 1 is down-cut, and when the other drive shaft 2a is aligned with the protruding direction of the mast 24 as shown in FIG. This is a reversal of the clockwise rotation shown by the arrow in the figure, that is, an up cut. As shown in FIG. 3, flat joining plates 25a and 2
5a, and the mounting plates 26, 26 and 27, 27 having pin holes 26a, 27a are connected to the joining plates 25a, 2.
The edge A of one joint plate 25a is fixedly attached to each of the joint plates 5a.
The edge B of the other joining plate 25b is formed to be shorter than the edge A.

8, so as shown in FIG.
8 pin holes 27a, 28a, 27a, 28a...
By inserting the pins 29... into the rear cover 8, the rear cover part 20 will be attached to the rear part of the main cover 8. In this down-cut state, the front edge C of the rear cover 17 will be attached to the main cover as shown in FIG. 8
Since the edge B is formed to be at a lower position than the edge B of X
Remove soil, pebbles, etc. from the rear cover 1.
The gap S will be closed by the leading edge C of No.7.

出すなどの心配もなくなつたのである。 As described above, the rear cover of the forward/reverse switchable rotary according to the present invention is arranged so that the front edge C of the rear cover 17 is located lower than one edge B of the main cover 8 when cutting down, and when cutting up the rear cover 17. Since the front edge C of the rear cover 17 is configured to be located higher than the other edge A of the main cover 8, when down-cutting, the edge of the main cover 8 is The gap S with the part B is closed in the rotational direction of the tiller 9, and
When the tiller is turned up, the gap S between the front edge C of the rear cover 17 and the front edge C of the rear cover 17 is closed by the lower edge A of the main cover 8 in the rotational direction of the tiller 9. In both rotation and reverse plowing operations, the gap near the hinge between the main cover 8 and the rear cover 17 is blocked, so soil, pebbles, etc. can get caught in this gap and prevent the rear cover from swinging. There is no longer any fear that the rear cover or the like near the hinge may be obstructed or deformed due to this, and there is also no need to worry about soil blowing out from the gap.

る効果を奏する発明である。 As described in the present invention, even during normal rotation (down cutting), some soil is carried around by the rotation of the tiller 9, but the front end C of the lower surface of the rear cover part 20
is located below the lower edge B of the main cover 8, so that the soil being carried around is not guided forward and gets caught in the connecting portion between the main cover 8 and the rear cover part 20. Also, when reversing (when turning up)
, the upper end of the rear cover part 20 is connected to the main cover 8.
Since it is located at a slightly higher position than the lower edge A, the soil that is plowed by the rotation of the tiller 9 and flows from the front to the rear on the inner surface of the main cover 8 reaches the lower surface of the rear cover part 20 at this lower edge A. This invention has truly great effects, such as being guided so that it does not get caught in these joints.
