Excavator bucket with adjustable bucket capacity

Abstract

The invention relates to an excavator component, and particularly discloses an excavator bucket with adjustable bucket capacity. The excavator bucket comprises a bucket body with an opening at the rear end and a bottom cover, a first hinge part is arranged at the lower end of the bucket body, and a guide rail is arranged on the upper inner side wall of the bucket body; the bottom cover is composedof a bottom plate, a strip-shaped plate and two arc-shaped plates, a second hinge part is arranged at the lower end, and a sliding block is arranged on the strip-shaped plate; the second hinge part is hinged to the first hinge part, and the sliding block is matched with the guide rail, so that the bottom cover is buckled at the rear part of the bucket body and can rotate, the bucket capacity is reduced when the bottom cover rotates forwards, and the bucket capacity is increased when the bottom cover rotates backwards; and a locking mechanism is arranged on the sliding block. The excavator bucket has the bucket capacity adjusting function, stepless adjustment can be conducted according to actual working conditions, and the operation efficiency can be improved to the maximum extent on the premise that stable work of the excavator is guaranteed; the bucket capacity is convenient and fast to adjust, and both time and labor are saved; and a spare excavator bucket is not required to be arranged, so that the equipment acquisition cost is reduced, and the defects of labor consumption, influence on the operation efficiency and the like caused in the transportation, dismounting and mountingprocess of the spare excavator bucket are eliminated.

Description

technical field [0001] The invention relates to an accessory of an excavating machine, in particular to a bucket for an excavating machine. Background technique [0002] The bucket is an important component of the excavator, and its capacity is one of the three most important parameters of the excavator (operating weight, engine power and bucket capacity). The bucket capacity of the original bucket is usually the standard bucket volume, which cannot adapt to all working conditions. For example, for light materials with low density, a bucket with a large bucket volume should be selected to reduce power consumption and improve work efficiency. For heavy materials with high density, a bucket with a small bucket capacity should be selected to avoid overloading the excavator and ensure its working stability. Therefore, excavators usually need to be equipped with multiple buckets with different bucket capacities to meet the needs of different working conditions. On the other han...

Therefore, excavators usually need to be equipped with multiple buckets with different bucket capacities to meet the needs of different working conditions. On the other hand, buckets are usually heavy and inconvenient to transport and carry. In particular, the disassembly and assembly operations during replacement are usually done manually, which is time-consuming and labor-intensive, and the labor cost is high. In addition, on the other hand, the bucket capacity specification of the bucket is Changes in steps, it is usually difficult to adjust the bucket capacity to the optimal value by replacing the bucket

[0003] At the same time, during the continuous operation of the excavator, the density of the material sometimes changes greatly with the progress of the operation. large, and the density difference between the upper and lower soils is relatively significant. In this case, changing buckets with different bucket capacities according to the actual situation is obviously conducive to improving operating efficiency and ensuring the working stability of the equipment, but it is limited by the replacement of existing buckets. It is difficult, coupled with unfavorable conditions such as terrain, it is generally not easy to replace the bucket, but to use the same bucket for continuous operation, which is obviously not scientific and reasonable

[0004] It is undeniable that among the bucket designs recorded in the existing literature, there are also plans to design the bucket capacity as adjustable, but the adjustment structure based on it is not scientific, and the stability is usually poor, especially the shape, Parameters such as curves and dimensions are quite different from those of existing buckets, and cannot meet the bucket processing parameter requirements accumulated over a long period of time, and fail to achieve better excavation performance. Because the technical effect does more harm than good, it has not been popularized and implemented.
