Excavator Screening Bucket
The excavator screening bucket is a core multi‑functional attachment compatible with excavators of various tonnages. Driven by the excavator's original hydraulic system, it needs no external power supply and no equipment modification. It can rapidly complete soil‑rock separation, sand‑gravel screening, waste sorting, material classification and other operations, completely replacing the working mode of traditional manual screening and large fixed screening machines. Boasting the core advantages of flexible relocation, suitability for both dry and wet materials, high efficiency and energy saving, it has been widely applied in engineering infrastructure, river regulation, construction waste recycling, landscaping earthwork treatment, mine material sorting and many other fields. It is core equipment to realize refined construction on site and reduce construction costs.
I. Core Working Principle of the Product
Adopting a hydraulically driven screening structure, the screening bucket is equipped with a high‑torque hydraulic motor and precision reducer, featuring stable power output and low transmission loss. After grabbing mixed materials, the equipment realizes rapid material classification through physical means of drum rotation or high‑frequency vibration: fine sand, powder and small stones fall quickly through the screen mesh openings, while large‑size stones, concrete blocks and sundries remain inside the bucket. On‑site screening and discharging are realized with short single screening cycles and clean separation without mixing, greatly improving material processing efficiency.
The whole machine operates synchronously with the excavator hydraulic oil circuit. It is easy to control with sensitive response, conforms to the conventional operation habits of excavators and requires no learning threshold for operators. It is perfectly suitable for outdoor mobile operations and scattered construction site scenarios.
About Shandong Hongxing Construction Machinery Co., Ltd.
Located in Jining, Shandong, Shandong Hongxing Construction Machinery Co., Ltd. is an original manufacturer focusing on the R&D, production and sales of full‑series hydraulic attachments for excavators. Equipped with complete processing production lines and a professional R&D team, the company can customize screening buckets according to customers' excavator tonnage and actual working conditions. The screen mesh aperture and bucket volume can be adjusted as required, and OEM service is supported.
Hongxing screening buckets are made of high‑strength wear‑resistant steel plates with thickened reinforcement at key stress positions. Hydraulic motors and reducers adopt reliable hydraulic components to adapt to long‑term high‑frequency heavy‑duty operations. Each machine undergoes complete pressure testing before delivery, with strict control over every production procedure.
Hongxing screening buckets provide mature solutions for various working conditions, including pebble screening in river dredging, construction waste recycling treatment, mine tailings separation and garden soil improvement. With ISO9001 quality system certification, our products are exported to many countries around the world. We offer complete after‑sales support including pre‑sales model‑selection guidance, delivery operation training and sufficient spare‑parts supply.
