Excavator bucket for constructional engineering

Abstract

The invention relates to an excavator component, and particularly discloses a bucket. The bucket comprises a bucket body with an opening in the rear end, a guide groove is formed in the upper wall ofthe bucket body, the rear lower end of the bucket body is hinged to a bottom cover, a guide block matched with the guide groove is arranged at the upper end of the bottom cover, the bottom cover rotates forwards, the bucket capacity is reduced, and otherwise, the bucket capacity is increased; and a traction base is arranged at the outer end of the guide block and hinged to a traction arm, and a threaded sleeve is arranged at the other end of the traction arm. A swing seat and a motor device are arranged above the bucket body, a main shaft driven by a motor device is arranged on the swing seat,and the main shaft is matched with the threaded sleeve so that the position of the bottom cover can be adjusted through rotation to achieve bucket capacity adjustment. The bucket has a bucket capacity adjusting function and can be adjusted according to actual working conditions, and the operation efficiency can be improved to the maximum extent on the premise that stable work of an excavator is guaranteed; the bucket capacity is convenient and fast to adjust, and time and labor are saved; and a spare bucket is not required to be arranged, so that the equipment acquisition cost is reduced, andthe defects of labor consumption, operation efficiency reduction and the like of the spare bucket in transportation, disassembly and assembly are overcome.

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 spare buckets with different bucket capacities to meet the needs of different working conditions. Cost input...

Problems solved by technology

Therefore, excavators usually need to be equipped with multiple spare buckets with different bucket capacities to meet the needs of different working conditions. Cost input. 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 capacity specification of the bucket It changes in steps, and 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 soil is more significant. In this case, changing the buckets with different bucket capacities according to the actual situation is obviously conducive to improving the working efficiency and ensuring the working stability of the equipment, but it is limited by the replacement of the 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 an adjustable type, but the adjustment structure based on it is not scientific, the stability is usually poor, and the adjustment is not convenient and quick enough, especially The parameters such as shape, curve and size adopted 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. failed to be implemented
