Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a shaping device for a ridge shaping machine that can shape a ridge while being pulled by a management machine.

[Prior Art] Conventionally, in a ridge shaping machine configured by connecting a rear shaping rotor having tail wheels on both sides behind a rotor mounted on the rear side of a management machine, the inner rear shaping board has a front-back direction. At the headland side, the ridge shaping work was started by lifting the handle of the management machine and slipping the wheels to act the inner shaping plate side.

[Problems to be solved by the invention] Raising the handle in such a manner is difficult to operate, and it is heavy and labor intensive, and the shaping work is started leaving the headland side. It had a problem.

[Means for Solving the Problem] The present invention solves such a problem and enables efficient and light ridge shaping work. Therefore, the internal shaping for the front side of both tail wheels is performed. Both resistance plates are vertically movably installed on the lower portions on both front sides of the plate, and both resistance plates and both tail wheels are movably installed so as to be movable in opposite vertical directions.

[Operation] Therefore, do not lift the handle like before.
As it is, land the inner trimming plate on the headland side, lower both resistance plates and raise both tail wheels, both resistance plates eat into the ground and become running resistance, and in that state, approach the headland side By starting the work from the position and then raising both resistance plates and lowering both tail wheels, it becomes possible to perform the ridge shaping work as the aircraft advances.

Example Next, an example shown in the drawings will be described.

FIG. 1 shows a side view of the whole, and in the management machine (A), an engine (7) is mounted in front of a mission case (6) in which wheels (5) and (5) are mounted on both sides of a lower portion,
A rotary work in which a base side of a handle (8) that is freely transferable in the front-rear direction is connected to the upper side of a mission case (6) and is connected to the rear of the management machine (A) via a rear hitch (9). The machine (B) includes a transmission case (10) in which a rotor (1) is mounted on both sides of a lower portion and the transmission case (6).
And a rotary case (11) are connected to each other via a counter case (11), and rotary covers (13) are erected on both sides of the rotary frame (12) to have the same structure as the conventional structure.

(3) is an inner wall shaping plate similar to the conventional type, and is fitted to a supporting portion (15) provided on the rotary frame (12) above the center of a supporting rod (14) which is horizontally mounted above it. A support rod (16) that can be fixed is extended, and both tail wheels (2) and (2) are installed on both sides of the internal shaping plate (3) as in the conventional type.

Both resistance plates (4) and (4) are vertically movably installed on both lower parts of the front surface (3a) of the internal shaping plate (3), but both upper and lower resistance plates extend from the back surface of the front surface (3a). Support (17)
(17) is inserted into the upper and lower long grooves (18) (18) of the resistance plate (4), respectively, and the resistance plate (4) is elastically erected by both springs (19) (19) so as to be vertically movable. The support rod (1
Operation rods (21) (21) are rotatably installed on both brackets (20) (20) fixed to both ends of (4), and the rear portions of both operation rods (21) (21) and both resistance plates ( 4) The upper part of (4) is connected via swing rods (22) (22),
A connecting rod (23) connected between the front portions of both operating rods (21) (21) and an operating lever (2) provided on the handle (8).
4) The operation wire (25) is installed between it and this.

Further, the front portion of the interlocking arm (27) whose intermediate portion is pivotally supported by the fulcrum shaft (26) is connected to the intermediate portion of the swing rod (22), and the tail wheel (27) is attached to the rear portion of the interlocking arm (27). The upper part of the supporting rod (2a) of 2) is connected, the return spring (28) is connected to the interlocking arm (27), and both resistance plates (4) (4) and both tail wheels (2) (2) are connected. And are so constructed that they can be interlocked with each other so that and can move in opposite vertical directions.

Therefore, when the inner trim shaping plate (3) is landed on the headland side and the operation lever (24) is operated in the direction of arrow (a),
It is possible to lower both resistance plates (4) and (4) in the direction of arrow (b) and raise both tail wheels (2) and (2) in the direction of arrow (c). While the lower part of) bites into the ground and becomes a running resistance, work can be started from the position closer to the headland side, and when the operation lever (24) is released after that, both resistance plates (4)
Since (4) goes up and both tail wheels (2) and (2) go down, the ridge shaping work can be performed as it is as the aircraft advances.

[Effect of the Invention] As described above, according to the present invention, the inner shaping plate (3) is landed on the headland side to lower both resistance plates (4) and (4) and raise both tail wheels (2) and (2). And, it is possible to start the work from the position where both the resistance plates (4) and (4) bite into the ground and come close to the headland side, so that the remainder on the headland side can be reduced and efficient ridge shaping work can be performed. Then, while raising both resistance plates (2) and (2) and lowering both tail wheels (2) and (2), they can be easily operated without the conventional operation of lifting a handle. As a result, the ridge shaping work can be carried out lightly, and the ridge shaping work can be suitably carried out.
