Abstract

PURPOSE:To enable the excavation work in front of a full-slewing type back hoe working vehicle to perform without any obstruction in sight by a method in which the pivotal supporting point for a boom and an arm is positioned in the neighborhood of the upside of the slewing center, and the slewing vehicular body is included within the slewing locus of the maximum outside end portion. CONSTITUTION:A pivotal supporting point Z for a boom 10 and an arm 11 is positioned at or near a slewing center X from front view of a slewing vehicular body 5. Both sides of a nearly equilateral triangle correspond with the upper portion of the bent portion of the boom 10 and the arm 11, and the tip of a bucket 12 is close to the inside of the bent portion of the boom 10. The slewing vehicular body 5 is included within the slewing locus S from plane view of the maximum outside end portion in relation to the slewing center X of the back hoe device 4. The minimum slewing radius of the slewing vehicular body can thus be greatly reduced. permitting the device 4 to work more easily in narrow places.

A backhoe device is provided on a running body equipped with a swinging machine equipped with a control section at the front and an original WJ section at the rear so as to be able to make a full turn (0J'), and which is pivotally connected to a boom, an arm, and a packet' in sequence. The present invention relates to a full swing type backhoe working machine in which a boom base end bracket is pivotally connected to be swingable about a vertical fulcrum placed on the front end of the swing machine body.

きる特徴を備えている。This backhoe work vehicle swings the base end bracket of the boom from its forward-facing position during normal work to the machine body at a nearly right angle, raises the boom significantly, bends the arm greatly, and rotates the packet approximately horizontally inward. It has the feature that the turning radius of the pack-hook turning body part can be reduced by moving.

回半径が未だ相当大きいものとなっていた。However, in the above conventional structure, when the eight-hook device is folded into the aircraft side and swung, the packet is located in front of the feet of the control section at the front of the revolving frame, so the backhoe device is placed next to the backhoe device. There is a limit to the approach to the aircraft body using the swing front, and as a result, the turning radius at the outermost end of the folded and swinging backhoe device as described above is still quite large.

大きく異なってしまう不具合があった。In addition, in the above conventional structure, in order to prevent the folding and swinging pack hook device from protruding greatly from the revolving frame, the vertical axis of the boom base end bracket is offset near one lateral end of the revolving frame. For this reason, when the backhoe device is placed in the normal excavation work position with the backhoe device facing forward, the backhoe device will be located in front of one of the traveling devices, and when excavating in the center of the left and right of the vehicle body, the swing frame will have to be widened. It was necessary to turn and bring the backhoe device closer to the center, and there was a problem in that the direction of the control section and the direction of the backhoe device were significantly different.

The purpose is to provide a backhoe work vehicle 1r.

The swinging machine (5), which has a vertical section (6) at the front and a front section (9) at the rear, functions as a full swing opening, and also has a boom (10), an arm (1) and a packet (1'4). The boom base end bracket (+4) of the back hook device (4), which is sequentially pivotally connected, can be freely swung around the vertical part, li't (Y), provided at the front end of the swing body (5). This is a fully swinging backhoe working machine which is connected by a pivot, in which the control section (6) is disposed on one side of the swinging body (6) at the center of swing (X), and the boom base end grout The vertical axis for swinging the circle (Y) k, the traveling gear on the opposite side of the control section (6) when viewed from the front rlt t
installed so as to be located between t+ and the turning center (x), and the boom (10) is formed into a nohi shape that is bent so as to protrude toward the back near the center in the longitudinal direction, The length of the arm (11) is determined by the boom (lLi)
Set the length to be close to the length of the upper part from the middle bending part of l, swing the boom base end bracket (14) at a substantially right angle to the control part (6) side, and raise the boom IILII to the maximum extent, Arm (refracts the river as much as possible, and further packets (12)
When the pivot point (Z) of the boom (10) and arm (11) is rotated inwardly to a substantially horizontal position, the pivot point (Z) of the boom (10) and the arm (11) is at the center of rotation (
X) or in the vicinity thereof, and the upper part of the boom (IIJI Both hypotenuses of an equilateral triangle are formed, and the tip of the packet 04 is formed close to the inside of the bend of the poom (lull), and is bent inward. The front part of the control part (6) is constructed so as to be inserted therein, and the maximum outer end portion of the backhook device (4) rotates in a plan view with respect to the center of rotation (X) in the 11th Q period's most steep folding position. Trajectory (S
Constructed so that the swinging machine (6) is included within J [Function] According to the above structure, the boom base end bracket circle is horizontally swung approximately at right angles from the forward facing position to move the backhoe device (4) closer to the machine body. , and in the state of folding and standing up to the maximum,
In order to fold and rotate the packet (12J) in the widest chamber area between the bending poom (10j and the arm (II17),
The refraction angle between the poom (10) and the arm (II) can be made sufficiently small. In other words, backhoe equipment! (4
), the distance between the outer end of the boom bending portion and the outer end of the packet pivot portion is sufficiently small. In addition, since the poom and arm pivot point (Z) of the backhoe device f4+ folded smoothly and narrowly in this way are located on or near the turning center (X) when viewed from the front, the backhoe device (pulling turning center ( X) to the outermost end (specifically, packet (10)
(the outer end of the base) is short.

Since the curved end of the control section (6) is inserted into the lower blade of the packet 02, the control section (6) can be installed sufficiently close to the front of the swinging aircraft (6). It becomes possible to bring the rear end of the driving part (9) behind the control part (6) closer to the turning center (X). As a result, it is possible to accommodate the rear end of the busy driving portion (9) within the turning trajectory (S) of the outermost end of the bank hook device (4).

The vertical axis (Y) that supported the unit (14) is the center of the aircraft of the pack hook device (4) facing forward, as it is installed between the traveling device fil7 turning center (phantom), which is a force when viewed from the front. There are few lateral installations from the side, and the packet (12
) can be positioned between the left and right traveling devices (t) and fit, and when excavating across a trench, work can be done without changing the orientation of the handle R1!5 (61) and the pack hook device f4+.
