When used, it is first recommended that the hydraulic system make it work normally, and then it is recommended that the main motor make the bucket chain part work, gradually lower the digging arm, and gradually dig the hopper from less to more until the full bucket operation. There are two methods for digging materials of hydraulic multi-bucket excavator, one is the fixed point digging method, then after the bucket chain part of the operation, relying on the hydraulic system to control the digging arm, the control of the digging arm is appropriate to the hopper full material, after the completion of digging, the digging arm will be raised higher than the height of the excavated data, that is, when the multi-bucket small excavator is walking, the digging arm will not touch the digging arm, and the operation will reach the material pile to be dug. Turn off the walking drive motor and lower the digging arm for digging material transport. The other is the walking digging method, after the bucket chain part of the operation, relying on the hydraulic system to control the digging arm, the control of the digging arm to the hopper to the appropriate position, adhere to the same view point of the digging arm, it is recommended to walk the driving motor, the hydraulic multi-bucket small excavator to walk at the set walking speed, so as to form a walking while digging, repeat the above operation can end the continuous uniform feed. The two mining methods have their own characteristics, and the former mining method is suitable for the independent pointed round pile (the pile formed by the air-controlled distributing mechanism); The latter mining method is suitable for a material pile with a straight appearance and a consistent height (a material pile made of a reversible distribution belt conveyor). In order to make the production sequential and orderly, trek power, the author personally prefers the latter method of digging materials.

Output value of hydraulic multi-bucket small excavator: The intention of using hydraulic multi-bucket small excavator is to continuously and evenly and quantitatively transport materials for the next process, so the output value of hydraulic multi-bucket small excavator has become a primary function policy of planning and manufacturing, and it is also an important basis for users to choose equipment. The output value of hydraulic multi-bucket mini excavator is related to the size of the hopper, the working speed of the bucket chain, and the trudging speed of the wheel, which are all inherent after planning and manufacturing. Another important factor in the output value of hydraulic multi-bucket small excavator is the digging depth of the digging arm. This factor depends on the proficiency of the operator of the hydraulic multi-bucket small excavator; The author measured a set of data in a brick factory, listed here for our reference. A brick factory uses SDW50 hydraulic multi-bucket small excavator, the wheel travel speed is 3.6m /min, the hopper volume is 0.045m (3 front mouth height is 250 mm), the bucket chain operation speed is 0.5m /s, and the digging material is the mixture of coal gangue and lake mud in the aging warehouse. In the use of different mining depth, the measured output value is different.

The application of hydraulic multi-bucket small excavator

Several points of attention should be paid to the operation and application of hydraulic multi-bucket small excavator: (1) Before each use, check whether the operation of each control switch is active and has no defects; Whether the hydraulic system is flexible and reliable, and whether there are obstacles on the working track; ② In the process of digging, prevent the digging arm from being lowered to the material engulfing the hopper so that the hopper part can work in the guessing process; ③ Prevent the reverse operation of the bucket chain; ④ prevent the adjustment of the hydraulic system in the process of use; ⑤ Punctual cleaning track adhere to clean without debris; ⑥ The main motor current should be checked at any time during the operation of the equipment; 7 When parking, the digging arm must be put down, not suspended; ⑧ Clean the residual materials on the digging arm after parking. Protection of hydraulic multi-bucket small excavator: The same as other machinery and hydraulic equipment, the protection and maintenance of hydraulic multi-bucket small excavator with the same needs the user to establish and improve equipment protection and maintenance criteria, implement three-level protection and maintenance criteria, do daily protection and maintenance, first-level protection and maintenance, second-level protection and maintenance, timely detection and cleaning of dangers, and adhere to the excellent condition of equipment function.
