Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for regulating the excavation range of an excavator provided within the main body of a V-μD excavator.

Conventionally, as shown in FIG. 1, there is a y-7%/do excavator in which the opening of the tip end of the PA excavator is configured to be movable forward, to the right, and downward. That is, inside the y-μ-do body 0) there is a slide plate + which is movable in the front and back direction.
4) A rotating plate fil that can freely rotate in a horizontal plane is provided on the top, and the company excavator (2) is supported on the axillary rotating plate so that it can freely swing in the vertical direction. Then, the above excavator (υ excavation I1
m! Three sets of circular abutting plates are attached to the outside 11 of the excavator (1) in order to regulate the area, and the above abutment plates 1al
An annular flange (I is attached to the turret body side) that restricts the range of movement.

However, according to sources, the dividend board I ship is m
II! Since it is installed immediately behind the middle section of the IJ machine (1), that is, the scoop section aS for transporting excavated soil, it has five drawbacks: it gets in the way of transporting the excavated soil.

Therefore, in order to eliminate the above-mentioned drawbacks, the present invention provides a predetermined swing of the excavator at the rear of the excavator PA machine, which is supported within the main body of the excavator so as to be swingable in the horizontal and vertical planes. If it has a guide hole corresponding to the movement range, a counterfeit body is provided, and a limit switch that can come into contact with the inner periphery of the guide hole of the model body is provided, and each rocking device of the Okukibori PAII is connected to the above 1t7) signal from the switch. It is set to 5 so that it can be controlled at night.

A tenth embodiment of the present invention will be described below with reference to FIGS. 2 to 5. 4 is a rotary excavator which is supported within the main body of Y-μD so as to be swingable in a horizontal plane and in a plane, and also to be movable in the front and rear directions. I21] T-111

This is a rotating plate that is swingable (swivelable) in a horizontal plane by a. The excavator section is supported on the rotating plate 6 via a horizontal shaft a'a, and the tcvgs V9 under device ◆Tsurunyyo 9 is swingable in the plane.

A limit switch (touch switch) which can be brought into contact with the inner periphery of the guide hole (19a) for the tracing weight is attached via a support arm. And the above second and gx
The control device is controlled by a signal from the limit switch. j5] Chi,
When the excavator (b) goes outside the excavation tunnel μ diameter, the 5g mitsu switch will have its tip contact (yi@a) contact the guide hole (l).
ilm) When it comes into contact with the inner circumference, I! A signal is issued to stop the swing and rotation of the machine mouth 10.

In addition, while swinging or turning in a certain direction! An interlock circuit is built in so that when the Mitsutwitch is operated and each Y99 controller-m stops, only the O-swing and rotation operations can be performed in the opposite direction to the fixed direction.

Next, the second embodiment will be explained based on Figure 1g@ and Figure 7. In the io embodiment, a rotary excavation machine was explained, but this O is also a bucket F type O excavator! %O having 1i11 will be explained. That is.

The rear end of the support body having a tilt (an ugly packet) at the tip is connected to the pivot shaft, and the support body 13t! The support body a+3 is made swingable in the lead OI plane by the F9 under device, and furthermore, the support a+3 is made swingable in the horizontal plane by the Y9 under device through the pivot axis. And m5tiii of the above excavation package)-! ! Guide hole to regulate g (xya
) is attached to the rear of the support 1130, and the seed body can be brought into contact with the inner periphery of the guide hole 07. A Mitsutswitch (-Butiswitch) is attached via a support arm. As in the first embodiment, the turning and swinging range of the S/9 body device-1 is restricted by the limit switch.

Next, the third embodiment will be described based on FIG. By installing the OFi RIMIP F switch on the side of the excavator, a truncated cone-shaped guide hole (41 mm ) is fixed separately to the excavator side, that is, to the seed main body side, so that the cross-sectional shape of the O excavation can be changed in the front-rear direction.

As described above, according to the device for regulating the excavation range of the present invention, since the tracing body and limit switch for regulating the excavation range are provided at the rear of the excavator, compared to the conventional O stopper type %O. Its structure is simple and does not interfere with the removal of excavated soil, and it is easy to adapt to any excavation shape by simply preparing various tracing bodies. By doing so, it is possible to perform excavation taking into consideration the movement of the PMS machine O in the front and rear directions.
