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 for engineering construction comprises a frame-shapedbucket body, a rope box is fixedly arranged in the bucket body, a rope wheel and a traction rope are arranged in the rope box, a bottom cover is rotatably and fixedly arranged at the rear end of thebucket body, a traction part is arranged at the upper end of the bottom cover, the traction part is connected with the traction rope, the bottom cover rotates forwards, the bucket capacity is reduced,otherwise, the bucket capacity is increased, a wheel shaft of the rope wheel is connected with a worm wheel, a worm which meshes with the worm wheel and a motor device which drives the worm to rotateare arranged in an inner cavity of a back plate, and bucket capacity adjustment can be achieved when the motor device drives the worm to rotate. The excavator bucket has the bucket capacity adjustingfunction, adjusting can be carried out according to actual working conditions, the operation efficiency can be improved to the maximum extent on the premise that stable work of a excavator is guaranteed; the adjusting operation of the bucket capacity is convenient and fast, time-saving and labor-saving; and a spare bucket is not required to be arranged, so that the equipment acquisition cost is reduced, and the 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 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 laborious, 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 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 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
