Excavator bucket for engineering construction

Abstract

The invention relates to an excavator component, and particularly discloses an excavator bucket for engineering construction. The excavator bucket comprises a bucket body, a main shaft and a pulley are arranged on the bucket body, a first rope wheel, a second rope wheel and a worm wheel are fixed on the main shaft, a traction rope bypasses the rear side of the pulley, and two ends of the tractionrope are wound on the first rope wheel and the second rope wheel respectively; a bottom cover is rotationally fixed to the rear end of the bucket body, a traction part is arranged at the upper end ofthe bottom cover and connected with the traction rope, and the bucket capacity is decreased when the bottom cover rotates forwards or increased otherwise; and a worm and a motor device are arranged inan inner cavity of a back plate, and the motor device drives the worm to rotate 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 andfast to adjust, and the time and labor are saved; and a spare bucket is not required to be arranged, so that the equipment acquisition cost is reduced, and the defects of labor consumption, operationefficiency 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 engineering machinery, in particular to an excavator bucket for engineering construction. 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 condition...

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 in engineering construction. This greatly increases the cost input. On the other hand, the bucket is usually heavy and inconvenient to transport and carry. In particular, the disassembly operation during replacement is usually done manually, which is time-consuming and labor-intensive, and the labor cost is high. In addition, on the other hand, the bucket Bucket capacity specifications change in steps, and it is usually difficult to adjust the bucket capacity to the optimum 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
