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, wherein a guide box and a gear seat are arranged on the upper side wall of the bucket body, the rear lower end of the bucket body is hinged to a bottom cover, a traction part is arranged at the upper end of the bottom cover, and the bucket capacity is reduced when the bottom cover rotates forwards, and is increased otherwise; and a joint rack is arranged in the guide box, a gear is arranged in the gear seat, the rear end of the joint rack isconnected with the traction part, the front portion of the joint rack is meshed with the gear, a worm wheel coaxial with the gear, a worm matched with the worm wheel and a motor device driving the worm to rotate are arranged in a back plate, and the motor device can drive the bottom cover to rotate so as to adjust the bucket capacity. The bucket has the bucket capacity adjusting function and can be adjusted according to actual working conditions, and therefore 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, so that 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 oflabor consumption, operation efficiency reduction and the like of the spare bucket in transportation, disassembling and assembling are eradicated.

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 laborious, and the labor cost is high. In addition, on the other hand, the bucket 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 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
