Description

[Detailed Description of the Invention] This invention relates to a device for attaching a rotary rear cover to a main cover.

For example, when attaching a ridge erector to a rotary, or when changing the connection direction of a so-called forward/reverse rotary rotary that can be connected to a tractor in either the front or back direction, remove the rear cover from the main cover of the rotary and then reinstall it. They can be attached in the same position or in reverse positions. This kind of removal and installation work of the rear cover is done by removing or inserting the hinge pin of the hinge section provided on the front edge of the rear cover, but it is necessary to remove the hinge pin while supporting this heavy and large rear cover with your hands. Or, it requires a lot of effort to align the hinge portions of both the main cover and the rear cover.

Therefore, in view of the above-mentioned defects, this invention was proposed to solve the problem, and a front cover of the rear cover is provided between the main cover and the rear cover of the rotary, and this front cover covers the front end portion of the rear cover. A mounting plate is provided upright on the left and right sides of the main cover, and mounting pieces that can be joined to the mounting plates are provided upright on the left and right sides of the main cover, and the front cover is attached to the main cover. It is an object of the present invention to provide a rear cover mounting device for a rotary, which is characterized in that the mounting plate and the mounting piece are mounted on the rear upper part of the rotary cover so as to abut the two sides, and the mounting plate and the mounting piece are joined together.

An embodiment of this invention will be described below in detail with reference to the accompanying drawings. The rear upper part 4 of the main cover 3 that covers the upper part of the tiller 2 of the rotary 1 is formed in a substantially horizontal shape, and the mounting tools 5 are erected at two or more places on the left and right of the rear upper part 4, so that the front upper part of the horizontal shape is formed. At least two mounting plates 8 on the left and right sides are provided on the front cover 7 having the main cover 6, and the front part of the rear cover 9 is hinged to the front cover part 7 with hinges 10. Place the mounting bracket 5 on the front upper part 6 of the front cover part 7 (at this time, the rear edge of the rear cover 9 is grounded on the ground).
and the mounting plate 8, and the pin hole 5 of the mounting tool 5.
When the pins 11 are inserted into the pin holes 8a of the mounting plate 8, the rear cover 9 is hinged to the rear part of the main cover 3 by hinges 10 so as to be vertically movable.

The illustrated hinge 10 has a concave arc-shaped hook 12 formed on the rear edge of the front cover part 7, a plurality of U-shaped hinge pieces 13, 13 fixed to the hook 12, and a front edge of the rear cover 9. A hook 14 is formed in the shape of a concave arc with a slightly larger arc radius than the hook 12, and the stay 15 is fixed to the back surface of the rear cover 9.
The front part is made to protrude forward from the hook 14, a cylindrical pin insertion part 16 is formed in this front part, a hinge pin 17 is inserted into the pin insertion part 16, and the hinge piece 1 is inserted into the pin insertion part 16.
Lift the rear part of the rear cover 9 while fitting the hinge pin 17 into the hinge pieces 13, 13 so that the pin insertion part 16 is located between the hooks 1 and 13.
If the rear cover 9 is rotated downward around the hinge pins 17 with the front edge of the hook 14 facing the rear edge of the hook 14, the hook 14 is fitted onto the hook 12 and attached to the hinge 10 as shown in FIG. Thus, the rear cover 9 is hinged to the front cover portion 7. Note that various other hinges may be used instead of the hinge 10.

In addition, an auxiliary cover 18 whose downward protrusion length can be adjusted is attached to the rear cover 9 with bolts 19, and a pin 2 is attached to the gear box 20 of the rotary 1.
The rear part of the support rod 22 pivotally connected at 1 and the rear cover 9 are connected by the support rod 23, and the vertical position of the rear part of the support rod 22 can be adjusted by rotating the adjustment screw rod 24. . The rotary 1 in the illustrated example is provided with a horizontal front upper part 25 and a mounting tool 5 at the front of the main cover 3, and in the state shown in FIG. the rotary 1 is connected with the work equipment connection device 27, the mounting plate 8 of the front cover part 7 is attached to the mounting tool 5 of the front upper part 25, and the tractor 26 is positioned facing right.
The rotary 1 is configured as a forward/reverse rotary that moves forward to the right in FIG.

Since the rear cover mounting device of this invention is constructed as described above, in order to install the rear cover 9, place the front cover part 7 on the rear upper part 4 of the main cover 3, and attach the mounting tool 5 and the cover plate 8 with, for example, pins. During this installation, the front part of the rear cover 9 is supported by the rear upper part 4 of the main cover 3, and the rear part of the rear cover 9 is in contact with the ground.
It is no longer necessary to support and hold the rear cover 9 with one's hands, so the installation work of the rear cover 9 can be done easily with less effort, and the need to support and hold the rear cover 9 with one's hands is also eliminated when removing the rear cover 9. It is.

That is, in this invention, mounting tools 5, 5 are provided on the left and right sides of the rear upper part 4 of the main cover 3 of the rotary 1, and mounting plates 8, 8 are provided on the left and right sides of the front cover part 7 hinged to the front part of the rear cover 9. the rear upper part 4 of the main cover 3
Since this is a rotary rear cover mounting device that is provided so that the mounting tools 5, 5 and the mounting plates 8, 8 can be joined together when the front cover part 7 of the rear cover 9 is placed on the seat, the rear part of the rear cover 9 must be grounded. When the front part of the rear cover 9 is tilted forward to approach the rear end of the main cover using this grounding part as a fulcrum, the front cover part 7 is moved downward around the hinge part to the mounting tools 5, 5 and the mounting plate 8. , 8, so that the rear cover 9 can be easily attached to the main cover 3.
