Description

[Detailed description of the device] [Industrial applications]

The present invention relates to the structure of an excavator bucket for an excavating machine (commonly referred to as Yumbo) used in various mines, steelworks, civil engineering construction sites, and the like.

[Prior art]

There are various types of conventional excavating machines such as bulldozers and power shovels, but these large heavy machines are often used in places where the work area is relatively large and easy to operate (operate). Here, a small machine commonly called Yumbo will be described. This machine includes a traveling device, a turning device, a boom and an arm, a hydraulic cylinder, a bucket, and the like. For the operation, a driver sits on a chair and operates various operation levers to perform excavation work. However, the design of this machine is such that the boom and arm are used facing upwards, and the fact that the bucket is manufactured as an ordinary excavator makes it possible to dig a hole on a flat surface, a large greenhouse, It has a relatively large space such as a road gutter, and is suitable for excavation work in the shape of a groove.

[Problems to be solved by the device]

However, if the bulk material you want to excavate and remove is under some structure (ground height of 1.5 m or less), these commercially available excavating machines are suitable because the arm, bucket, etc. will come into contact with the upper structure. I can't use it. Therefore, when iron ore etc. are deposited under these conveyor belts in these places,
Since this deposit ore (hereinafter referred to as "falling mine") must be removed manually, many people are investing it in the process. The present invention is intended to enable a general-purpose excavator such as a Yumbo to perform work that is difficult or impossible with such a conventional excavator.

[Means for Solving the Problems]

As a result of studying the above-mentioned problems, the present inventors have proposed a bucket to be attached to the arm tip of an excavator such as a Yumbo. The mounting arm (2) is extended only on one side of the bucket body (3), and the mounting arm (2) is provided with a mounting bracket (13) to the tip boss of the excavator arm (1). We have developed a cantilever bucket for excavators.

[Action]

The cantilever bucket for an excavator of the present invention has a horizontally long gutter shape and is provided with a partition plate inside to reinforce and to prevent the scooped material from moving in the left-right direction. Even if the bulk object you want to excavate and remove is under some structure, it has a cantilever structure, so the arm, bucket, etc. do not contact the upper structure like a commercial excavator. Only buckets can enter and scoop under these. If the outrigger (4) is set on the excavator according to the needs of the site where the mine is removed, stable work can be performed if the mine is removed using a bucket.

【Example】

1 is a front view of a cantilever bucket for an excavator of the present invention, FIG. 2 is a plan view of the same, and FIG. 3 is a left side view of the same. FIG. 4 is a perspective view of an excavator equipped with the bucket of the present invention. The excavator shown in FIG. 4 of this embodiment is a small excavator called a commercial Yumbo. It is the same as the conventional structure in that it is equipped with a hydraulic system with an engine, and is equipped with a caterpillar (6) for traveling, an arm (1), and a hide plate (5). A special bucket is provided so as to project rightward with respect to the boss at the tip of the arm (1) of the excavator. This bucket is replaceable. The bucket is made as thin as possible from the bucket movable portion of the tip boss to the bucket body (3) to have strength. This makes it easy to use. The bucket body (3) is formed in a laterally long gutter shape, the mounting arm (2) is extended only on one side of the bucket body (3), and the excavator arm (1) is attached to the mounting arm (2). ) Mounting bracket for tip boss (1
3) is provided. A partition plate (3a) is attached to the inside of the bucket body (3) to give it strength. As a result, the effect of preventing twisting and cracking can be obtained. The bucket body (3) has a cutting edge (2 faces) provided with a claw (3b) for reducing the load during excavation and for preventing wear. In addition, it is preferable to provide outriggers (4) and (4) on both sides of the hide plate (5) at the front of the excavator for stability. Although not shown, the hydraulic system of the outrigger (4) is connected to the hydraulic system of the hide plate (5) through a hydraulic pressure switching valve, and by switching from the hide plate side to the outrigger side, the driver's cab is moved to the operation lever (7). The outrigger (4) can be controlled. That is, the outrigger is operated by the operation lever (7) on the hide plate near the driver. Here, the usage of the cantilever bucket for excavator of the present invention will be described. First, the conventional bucket tip boss is removed at the movable portion, and the bucket (3) of the present invention is mounted. The small Yumbo (20) equipped with this special bucket goes to the destination while running, leaning and turning, and sets the outrigger (4) by using the operation lever (7). Next, align the bucket (3) with it lying down on the surface of the orefall (10), and make a slight left swing (from the driver) as shown in Fig. 5.
And put it under the belt conveyor frame (11). Then, gradually rotate the bucket (3) toward the front by the operating lever (7) and scoop up the fallen ore (10). While making a slight right turn, lift the bucket (3) from below the belt conveyor frame (11). Pull out. Then, raise your back and stop at an appropriate height, then turn left. The bucket (3) is inverted on the conveyor belt (12), and the falling ore (10) is placed on the conveyor belt (12) in the state shown in FIG. By repeating the above operation, the fallen mine can be recovered.

[Effect of device]

Since the present invention has the above-mentioned structure, it is an apparatus capable of picking up loose objects in a narrow upper and lower space. In particular, the present invention has made it possible to remarkably improve the efficiency of recovery work of fallen mine in a narrow space such as below the conveyor belt.
