Abstract
The invention relates to a novel energy-saving loader and a control method thereof. A third movable arm is further arranged between a first movable arm and a second movable arm. The end of the third movable arm is connected with a bucket, and a third movable arm oil cylinder is arranged below the third movable arm. A first movable arm oil cylinder and a second movable arm oil cylinder are both energy storage oil cylinders. According to the energy storage oil cylinders, oil cylinder bodies are connected with energy storage reservoirs through a pipeline. The third movable arm oil cylinder is a power oil cylinder which is controlled by power. Or the first movable arm oil cylinder and the second movable arm oil cylinder are both power oil cylinders, and the third movable arm oil cylinder is an energy storage oil cylinder. In the energy storage reservoirs, hydraulic oil is arranged on the lower portions, and pressure air is arranged on the upper portions. When the movable arms descend, hydraulic oil in the energy storage oil cylinders is pushed into the energy storage reservoirs, and therefore the air on the upper portion in the energy storage reservoirs is compressed for energy storage. When the movable arms are lifted, the compressed air on the upper portions in the energy storage reservoirs pushes the hydraulic oil to enter the energy storage oil cylinder again, power is provided for lifting of the movable arms, and therefore energy consumption of an engine is reduced.

Detailed description of the invention
As shown in Fig. 3, Fig. 1, scraper bowl 9 connects rotary ink tank 6 through rotating bucket pull bar 10, rocking arm 11,
It is hinged with rotary ink tank that vehicle frame is provided with rotary ink tank bearing, first swing arm the 12, second swing arm end
Connect scraper bowl 9, below the first swing arm 12, be provided with the first boom cylinder 1, below the second swing arm, be provided with
Two boom cylinders 2, this is prior art.As it is shown in figure 1, between the first swing arm, the second swing arm
Being additionally provided with the 3rd swing arm, the 3rd swing arm end connects scraper bowl, is provided with the 3rd swing arm oil below the 3rd swing arm
Cylinder 3；First boom cylinder and the second boom cylinder are energy storage oil cylinder, described energy storage oil cylinder i.e. oil
Cylinder connects accumulation of energy bin by the road, and the 3rd boom cylinder 3 is that actuator cylinder is i.e. by dynamic Control
Oil cylinder；Or first boom cylinder the 1, second boom cylinder 2 is actuator cylinder, the 3rd swing arm
Oil cylinder 3 is energy storage oil cylinder.
As shown in Figure 4, in the present embodiment, first boom cylinder the 1, second boom cylinder 2 is for storing
Energy oil cylinder, energy storage oil cylinder connects accumulation of energy bin 5 by pipeline 4, in accumulation of energy bin 5, bottom
For hydraulic oil, top is for there being pressure air, and accumulation of energy bin 5 connects hydraulic power unit 7.3rd swing arm oil
