Basic design requirements for loaders

When designing the loader, it is stipulated that the linkage mechanism composed of bucket, bucket rod, crankshaft, bucket cylinder, boom, boom cylinder and frame is fixed to each other. The following points should be ensured during loading and cutting machine operation.
(1): The moving ability of the bucket. When the bucket cylinder is locked, the boom rises under the action of the boom cylinder, and the linkage mechanism can keep the bucket moving or make the bottom plane of the bucket intersect with the plane. Changes should be kept within the allowable range to prevent the bucket filled with materials from tilting and materials shaking off.

(2): A certain unloading angle. When the boom is in any working position, the bucket rotates around the hinge point according to the linkage mechanism under the action of the bucket cylinder, and the unloading angle is not less than 45°.

(3): The automatic leveling capability of the bucket means that when the boom is lowered, the bucket can be automatically leveled, thereby reducing the driver's labor intensity and improving productivity.

The design content of the loader's working device includes: determining the structural characteristics of the working device according to the work objectives and working conditions, completing the structural design of the bucket, bucket rod, and linkage mechanism, and completing the design of the loader's hydraulic system. Work equipment.

According to the optimized design of the wheel loader working device, its scientific research results should be intelligent, intelligent, and modular, and focus on the green design of the designed products. While manufacturing, using, maintaining and repairing in accordance with the design requirements, the design objectives should be estimated to achieve:

(1) The working ability is strong, and the resistance when the bucket is inserted into the pile should be small;

(2) Large excavation capacity and low energy consumption in the pile;

(3) All components of the working mechanism are in good stress condition and have reasonable strength and service life;

(4) The structure and work specifications must meet the production conditions and be efficient;

(5) Compact structure, easy to manufacture and maintain, and convenient to operate and use.
