Sunflower harvester

 Technical parameters and performance indicators of 4skf-4 self-propelled sunflower harvester
1. Technical parameters:
Dimensions: 8120X2670X3360mm
Machine quality: 7000KG (transport parameters)
Maximum unloading height: 2480mm
Maximum unloading height: 1770mm
Minimum turning radius: 8.15m left, 5.9m right
Number of job lines: 4 lines (large lines 800-1000, small lines 300-500 are applicable), the inserter is not correct.
Minimum ground clearance: 300mm
Grain silo capacity: 4m³
Seed tray bin volume: 4.5m³ (operation parameters)
Supporting power: 103KW (140 hp)
Pure working efficiency: 10-15 acres / hour
Fuel consumption per mu: 0.8KG / mu (at a speed of 2.7KM / hour)-(economic parameters)
2. Performance indicators:
Grain impurity ratio ≤18%
Total loss rate
Grain scratch rate ≤ 4
Kernel breakage rate ≤1
2. (1) Under normal operating conditions, the lodging angle of the plant is less than 30 °, the height of the disc from the ground is greater than 50 cm, and the moisture content of the grain is 15% to 25%.
1. Reason 1: The lodging angle is too large: feeding is difficult, it is difficult for plants to enter the channel, and the plants are congested horizontally, pushing the plants in front.
2. Reason 2: The height of the faceplate is less than 50CM, and the performance of the header cannot be reached (after falling to 50cm, the inclination angle, crop characteristics and mechanical properties cannot meet the harvest requirements)
3. Reason 3: Too much moisture in the grains will cause scratches and break the grains. (Crop moisture content is directly related to crop maturity. Generally, crops with high moisture content have the following characteristics. Affects the work effect.)  Basically, the whole sunflower is light brown.
(II) Special operating conditions
Plot size: It should meet the minimum turning radius of the equipment.
Flatness of the plot: The horizontal and vertical slope is not greater than 8 ° during operation or transfer, and the flatness of the plot should not be greater than 300mm (except for gentle slopes, which refers to raised bumps here)
Ground firmness: the machine is not suitable for slippery and deep subsidence land (slope, sandy land with large slope)
