1. What is an excavator screening bucket?
The excavator screening bucket is a multifunctional auxiliary tool for engineering machinery that can be installed on excavators and other equipment. It can complete a variety of operations, including screening and crushing of solid materials, and can also handle various types of materials. For example, the excavator rotary drum screening bucket mentioned in the introduction to smart manufacturing is suitable for sorting natural materials before and after crushing, which can shorten the crushing time by 60%, recover materials suitable for the required processing type and manage them. It adopts an inching hydraulic system, which can screen even wet materials, increasing production by 30% year-on-year. The rotary screening bucket drum screen is mainly used for rotary screening of sand and stone products. Because it often uses water washing methods, it is also called a water washing screening bucket. It is suitable for water washing operations of mountain sand and river sand, gravel screening in waterways, and sand fields, mixing stations, construction sites and other working conditions with high mud content.
2. How to use the excavator screening bucket?
The use of the excavator screening bucket mainly includes the following steps: 1. Installation After the product arrives at the construction site, open the package and carefully check whether each part meets the contract supply requirements and whether there is any damage. Otherwise, contact the manufacturer in time. The hydraulic system oil port and other exposed port plugs and wrappings must not fall off before the equipment is piped to avoid contamination of the hydraulic system. Before connecting the pipeline, be sure to check the product parameters to ensure that the excavator output oil pressure and other parameters are consistent with the rated parameters of the screening bucket. All fastening bolts and joints must be tightened as required to prevent leakage and environmental pollution. 2. Start the motor Start the motor to retract the traction rope into the rope drum, and start the telescopic rod to extend the conveyor belt out of the outer bucket of the screening bucket. Connect the power supply of the third electromagnet so that the rotating shaft is magnetically connected to the third electromagnet, and start the motor to drive the conveyor belt to move and transport sand and gravel. 3. Turn on the electromagnet and other operations Start the connecting shaft to raise the slideway to ensure that one end of the conveyor belt and the tail end of the conveyor belt remain on the same slope. When the inner bucket of the screening bucket is full of sand and gravel, start the fourth motor to drive the conveyor belt to retract the inner bucket of the screening bucket, close the sealing door at the same time, and start the electromagnet to seal the sealing door and the outer bucket of the screening bucket. Start the third motor to drive the outer bucket and the inner bucket of the screening bucket to rotate and screen the sand and gravel, and pour it out after the screening is completed. When pouring out, it is necessary to extend the second conveyor belt, and keep the third motor rotating at a low speed while pouring. Preparation before the excavator drum screening bucket: After the installation of all parts of the drum screen and the inspection is qualified, the test run can be carried out. Before the test run, check in detail whether all parts and fasteners are firm, and whether there are obstacles around the screen body that hinder the operation of the drum screen. Check that all bearing seats and gearboxes should be well lubricated and the gearbox oil level should be appropriate. Manually rotate the screening drum to observe whether the drum screen is stuck or rubbed. If so, it can be adjusted by adjusting the bolts. The hydraulic joint should be firm and reliable, and well insulated. No-load test run of the drum screening bucket of the excavator: Move the foot valve to check whether the drum screen is turning normally. Start the equipment and run it for 4-6 hours, observe the operation of the drum screen. If abnormal sounds or other phenomena are found, the machine should be stopped for inspection in time to find out the cause and eliminate the fault. Check the tightening of the fastening bolts at various places. If they are found to be loose, they should be tightened in time. Check the temperature rise of the motor and rolling parts, which should be within the normal range. Feeding of the drum screening bucket of the excavator: When the drum sand screening bucket of the excavator is in a stable operating state, conduct a feeding test run. Check the particle size of the discharge material and whether there is leakage and dust. After running for half an hour, conduct a thorough inspection of each component. The operation should be checked frequently during the work process. If abnormal operation or abnormal sounds are found, the machine should be stopped for inspection in time to find out the cause and eliminate the fault.
3. The function of excavator screening bucket
Excavator screening buckets play an important role in many fields. First of all, in terms of material screening, it can screen many different types of materials, such as topsoil, excavated soil, muck, contaminated soil, clay, peat, bark, compost materials, other solid organic matter, demolition waste, construction waste Garbage, milled asphalt, glass and other waste, coal, oil shale, limestone and other soft rock mineral materials, etc. It can be used to classify large and small stones and separate soil and stone powder in stone quarries; it can be used to separate sand and gravel in sand and gravel fields; it can be used in the coal industry to separate lump coal and coal powder and wash coal; it can be used in the chemical industry and mineral processing industry to classify large and small lumps and Separate powdery material. It is also widely used in municipal administration, agriculture, forestry, water conservancy, earth and stone engineering, etc. It is especially suitable for screening materials with smaller particles. Secondly, it has significant advantages in improving work efficiency. The trommel screen improves the working efficiency of screening materials. The improved trommel screen adds a sand blasting device in the screen cylinder to break and disperse the lumped materials, thereby increasing the material screening efficiency; a mesh surface cleaning device is installed on the screen surface. , avoid clogging the mesh and improve screening efficiency. The sand washing machine equipment has a series of functions such as "feeding, screening, washing, discharging and stacking". The screening and washing are completed in one go. It has a high degree of automation, saves labor, has reasonable output and high cleaning rate. It plays an important role in sand and gravel fields, mixing stations and other industries. Finally, in terms of reducing production energy consumption, the excavator screening bucket adopts the rolling conveying principle, which has a small friction coefficient, low belt power and low energy consumption. The whole machine has high reliability, adopts cycloidal reduction transmission, and has high transmission efficiency. For example, the excavator's rotating drum screening bucket mentioned in the Introduction to Intelligent Manufacturing uses an inching hydraulic system to screen even wet materials, increasing output by 30% year-on-year and effectively reducing production energy consumption.
