In FIG. 1, a vehicle 1, such as a conventional bucket loader, is equipped with an extensible member 2 that extends forward of the vehicle 1 and is driven to extend and contract in the direction in which it extends. The illustrated example of the telescopic member 2 is a non-retractable boom member 20 whose base end is pivotally supported by the body frame of the vehicle 1 to allow angular movement (hereinafter referred to as "depression") in the vertical direction.
and a telescopic boom member 2 sequentially connected to this.
1 and 22 and extend toward the front of the vehicle 1, and each of the telescopic boom members 21 and 22 is connected to a hydraulic system (not shown) on the vehicle side. It consists of a so-called boom with a three-stage telescoping cylinder configuration. The extensible member 2 is held by a depression driving means 3 and is driven to be depressed in the vertical direction. The illustrated example of the downward restraining driving means 3 consists of a lift hydraulic cylinder existing in the vehicle 1, and its free end is connected to the non-extendable boom member 20. A bucket bag 4 is pivotally supported at the tip of the telescopic boom member 22 of the telescopic member 2 via a pin P so as to be rotatable in the front-rear direction. Furthermore, gear portions G1 are integrally formed at both ends of this pin P. The upper part of the bucket 4 has a telescopic boom member 2.
It is pivotally supported at the tip of the roller 2 so as to be rotatable in the front and rear direction, with the opening side facing the vehicle 1, and is driven by a reversing drive means 5. A digging blade structure 7 is integrally planted on the upper surface of the bucket 4. The digging blade structure 7 has a ripper or rake structure in which a plurality of shank 71 each having a cutting edge 70 are arranged at regular intervals in the lateral direction and are integrated (see FIG. 2). On the other hand, in the case of this embodiment, the reversing drive means 5 is
It consists of a hydraulically driven rotary gear connected to a hydraulic system (not shown) on the vehicle 1 side, and is coaxial with the pin P that pivots the bucket belt 4, and meshes with a gear portion G1 formed on the outer end thereof. It has a portion G2, and is held so that the bucket 4 can be rotated to an appropriate rotation angle and work can be carried out in that position. Next, the operation of the above embodiment will be explained. The vehicle 1 is run in a state where the telescopic member 2 is shortened and held in the depression angle direction by the depression suppression driving means 3, and the telescopic member 2 is directed in a predetermined working direction, for example, in the direction of the belt conveyor B shown in FIG. to stop vehicle 1. In this state, when the elastic member 2 is depressed and lowered by the extension operation of the depression drive means 3, and the elastic member 2 is extended by hydraulic drive, the bucket 4 at the tip is removed from the piled up area below the belt conveyor B. Head towards Tasakimono W and enter. After this approach, the depression driving means 3 is extended and the bucket 4 is grounded near the piled-up material W below the belt conveyor B. At the time of the ground contact, the digging blade structure 7 is rotated upward. When the telescopic member 2 is shortened after touching the ground, the bucket 4 is used to scrape up accumulated debris W such as fallen ore and fallen coal below the belt conveyor B, and the reversing drive means 5 drives the bucket 4 to rotate. As a result, the accumulated materials W are scooped up by the bucket 4, and the accumulated materials W are later recovered by the downward movement of the telescopic member 2. In the process of scraping and collecting such accumulated materials W,
When it is necessary to crush or dig up a hard object, the gear part is
When G2 is rotated to an appropriate reversal angle (for example, 180 degrees), the gear portion G1 that meshes with G2 is rotated at the same angle, and the bucket bag 4 is reversed at a predetermined angle via the pin P serving as the rotation axis. Therefore, in this state, the digging blade structure 7 performs operations such as crushing and digging up hard materials. After that work, the reversing drive means 5
When the bucket 4 is returned to its original position, the crushed materials and dug-up materials can be scooped up and recovered by the bucket 4. In the embodiment shown in FIG. 3, a leveling tool 9 is detachably installed from the cutting edge side of the digging blade assembly 7 extending above the bucket 4. In this case, the ground can be leveled with the leveling tool 9 by repeating the depression and expansion/contraction of the expandable member 2. FIG. 4 shows a different embodiment in which the telescopic member 2 is installed at the front of the vehicle 1 and extends laterally. In this embodiment, a frame 40 is provided on one side of the front part of the vehicle 1, and a pair of compression members 2 are attached to the frame 40.
It has a configuration in which it extends in the lateral direction of the vehicle 1. A horizontal member 41 is spanned between the telescopic members 2, and the center of the horizontal member 41 and the front frame 40
The illustrated example has a hydraulic cylinder 3, which is a downward depression drive means, attached to the bottom. Since the other configurations are the same as those in the previous embodiment,
Identical components are given the same reference numerals and their explanations will be omitted. Therefore, the operator drives the vehicle 1 and stops it in the longitudinal direction of the belt conveyor B, and without changing the direction of the vehicle 1 or the position of the operator, performs scraping work or crushing while visually observing the vehicle 1.
Since the digging work can be selectively performed, the above work can be carried out smoothly and efficiently, especially at work sites where the road width is narrow, such as between belt conveyors B. FIG. 5 shows a different embodiment in which a telescopic member 2 with a bucket 4 attached to its tip is attached to a vehicle 1 via a turning device 30. That is, in this embodiment, the turntable 31 of the swing device 30 has a well-known configuration that is rotationally driven by a hydraulic motor (not shown), and is removably mounted on one side of the front part of the vehicle 1 via a frame 32. It is based on an on-vehicle crane. The turntable 31 has a mast 33,
The mast 33 supports the telescopic member 2. The extensible member 2 has a base end supported by the mast 33 via a pin P2 so as to be able to be depressed vertically. The telescoping member 2 is driven downward by a hydraulic cylinder 3 as a downward movement driving means mounted between the non-extendable boom member 20 and the mast 33. Since the other configurations are the same as those in the previous embodiment,
Identical components are given the same reference numerals and their explanations will be omitted. Thereby, the telescopic member 2 can be rotated, and the working range of the bucket 4 and the digging blade assembly 7 can be further expanded, which is preferable. In this invention, the structure for attaching the telescopic member to the vehicle is not limited to the above-described embodiment, but may be fixedly or rotatably attached to the rear of the vehicle or elsewhere. Further, in this invention, the digging blade structure may have its tip protruding onto the bucket from the back side of the bucket. Further, as the driving means for the bucket cart, a link mechanism or other known driving means can be used as long as it is a mechanism for inverting the bucket cart approximately 180 degrees.

Bucket work and ripper or rake work can be performed selectively at any time without replacing parts.
