Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a rotary unit-integrated management work machine, and more particularly to a leveling plate attaching / detaching device attached to a tail part of the rotary cover.
[0002]
[Prior art]
In conventional rotary unit-integrated management machines, the leveling plate is attached to the tail of the rotary cover so as to be swingable via a hinge. The resistance rod was pulled out from the mounting holder tube, and the attachment connecting rod was inserted from below the mounting holder tube to fix it.
[0003]
According to this means, it is possible to save the trouble of removing the leveling plate (the leveling plate remains in a state of being lifted up), and it is possible to connect the attachment by simply removing the resistance rod. However, when connecting the attachment, In order to obstruct, the troublesome trouble that the connecting rod must be inserted by hand search from the lower side of the resistance rod mounting holder cylinder is forced. In addition, since the leveling board lifted up from the hinge is unstable, there is a problem that unpleasant noise is generated during work.
[0004]
[Problems to be solved by the invention]
The present invention has been made in view of the above circumstances, and when connecting attachments, the leveling plate can be easily removed (it is easy to attach later), and the attachment connecting rod is a resistance rod mounting holder cylinder. It proposes a technical means that can be inserted and fixed without difficulty (without an obstacle) from above , and that the leveling plate does not fall off during use and that no unpleasant noise is produced.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, in the present invention, in the rotary unit-integrated management work machine 1, the pivoting pieces 7 of the leveling plate 2 project from both ends of the rotary cover 4 having the resistance rod mounting holder cylinder 5 at the rear center. To do.
[0006]
On the other hand, the leveling plate 2 is provided with a pivot 2a having different lengths at the base end .
The width of the base end of the leveling plate 2 is made shorter by the protrusion of the pivot 2a on the short axis side than the inner dimension between the pivot pieces 7 and 7 of the rotary cover 4.
And after inserting the long axis side pivot 2a deeply into the pivot holes 7a, 7a provided in the pivot pieces 7, 7 from the inside of the pivot pieces 7, 7 of the rotary cover 4, By inserting the pivot 2a on the short axis side so as to return, the pivot can be removably supported.
Then, the base portion of the short shaft side pivot 2 a comes into contact with the pivot piece 7, and the split pin 8 detachably attached to the long shaft side pivot shaft 2 a in the stopped state is mounted so as to contact the inside of the pivot piece 7.
[0008]
Then, a leveling plate attachment apparatus in a rotary unit integrated management working machine comprising mounting towards the mudguard rubber cover 6 to the rear edge of the rotary cover 4 obliquely rearward.
[0009]
[Operation and effect of the present invention]
In the present invention, as described above, the pivot pieces 7 and 7 provided at both ends of the tail portion of the rotary cover 4 are pivotally supported by the split pins 8 so that both ends of the pivot 2a at the base end of the leveling plate 2 can be attached and detached. Therefore, when attaching the attachment A, the leveling plate 2 can be easily removed by removing the split pins 8. After that, the resistance rod R is removed from the mounting holder cylinder 5, and the connection rod a of the attachment A is inserted and fixed from above the mounting holder cylinder 5.
Further, due to the stopper action of the split pin 8, it is possible to reliably eliminate the possibility of falling off due to mutual dance (swing) between the rotary cover 4 and the leveling plate 2 during work.
[0010]
That is, according to the present invention, it is not necessary to perform the connecting work by the downward groping when attaching the attachment as in the prior art (the leveling plate does not interfere), and labor-saving and quick attachment attachment can be performed in an open state from above.
Further , as shown in FIG. 1 , the leveling plate is held in a state of being slightly pushed up rearward by the mudguard rubber cover 6 so that the tail end of the rotary cover 4 and the plate surface of the leveling plate 2 are in direct contact with each other. The mudguard rubber cover 6 has a rubber cushioning action, which eliminates the generation of unpleasant noise during work.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
In FIG. 1, reference numeral 1 denotes a small rotary unit-integrated management work machine, which has a resistance rod mounting holder cylinder 5 in the center of the rear portion thereof, and a mudguard rubber cover 6 mounted obliquely rearward on the rear edge. 4 and the pivot piece 7 of the leveling plate 2 is projected from both ends of the tail.
[0012]
On the other hand, the leveling plate 2 has a pivot 2a attached to the base end thereof, and both ends of the pivot 2a are pivotally supported in a pivotal support hole 7a of the pivoting piece 7 of the rotary cover 4 through a split pin 8. A leveling plate attaching / detaching device is configured.
Regarding the relationship between the pivot piece 7 and the pivot 2a, both sides of the base end of the leveling plate 2 are shorter than the inner dimension between the pivot pieces 7 and 7 of the rotary cover 4 by the amount of protrusion of the pivot 2a on the short axis side. The long shaft 2a is first inserted deeply into the pivot hole 7a of the pivot piece 7 of the rotary cover 4 and then the short shaft 2a is inserted so that the rotary cover 4 can be removably supported. To do.
Further, regarding the relationship between the pivot piece 7 and the pivot 2a and the split pin 8, the base portion of the minor axis 2a hits the pivot piece 7 and can be attached to and detached from the major axis 2a in a stopped state. The pin 8 can be mounted so as to contact the inside of the pivot piece 7.
Due to such mutual relationship, the base of the pivot 2a on the short axis side is in contact with the inside of the pivot piece 7, and the split pin 8 attached to the pivot 2a on the long axis side is in contact with the inside of the pivot piece 7. In this state, the axial movement of the leveling plate 2 is restricted.
