What is the function of the front shovel machine?

In road construction, especially in high-quality road construction, the front shovel machine is used for filling and excavating road works, aggregates and loading asphalt mixtures and cement concrete yards. In addition, he can also perform tasks such as pushing soil, scraping the soil and pulling other machines. Since the front shovel machine has the advantages of fast operating speed, high efficiency, good maneuverability and easy operation, it has become one of the main types of earthworks in civil engineering.

How does the front shovel machine work?

When the high front shovel machine is in operation, the working equipment should be able to ensure that: when the bucket cylinder is locked and the boom cylinder is raised or lowered, the articulated mechanism moves the bucket up and down or almost moves to translation, so as to prevent the bucket from tipping and scattering materials; If the boom is in any position and the bucket rotates around the boom pivot point for unloading, the bucket tilt angle is no less than 45°, and the bucket can be automatically leveled when the boom is lowered after unloading.

What are the structural features of the front shovel machine?

The shovel structure of the high front shovel machine is used for earthwork. The blade body is usually welded with low-carbon, wear-resistant and high-strength steel plates. The blade is made of wear-resistant steel with medium manganese alloy. The side edge and the reinforcement angle are made of high-strength steel. Made of wear-resistant steel.

There are four types of bucket cutters for high front shovel machines. Factors such as insertion resistance, wear resistance and interchangeability should be taken into account when selecting the tooth profile. Teeth-shaped lower teeth and dull teeth, tire loaders mostly use tines, and crawler loaders mostly use dull teeth. The number of blade teeth depends on the blade width and the blade tooth pitch is generally 150-300 mm.

How do I operate the front shovel machine correctly?

When the front shovel machine is working, the foot plate should be separated from the brake pedal and placed flat on the floor of the cab and should not be stepped on the brake pedal. Loaders often work on uneven construction sites. When the foot is always on the brake pedal, the body moves up and down, causing the driver to carelessly step on the brake pedal.

Under normal circumstances, the front excavator machine uses the method of controlling the throttle lever to delay to control the condition and shifting. This not only avoids overheating of the braking system due to frequent braking, but also brings comfort when speeding up the loader.

When the front shovel machine is working, especially when the shovel is working, when the accelerator pedal is stable, the shovel should be filled with materials by cyclically pulling the joysticks for lifting and shoveling.
