GB/T 29003-2012Head-feed combine harvester - Evaluation index and measurement methods for fuel consumption (English PDF)

3.1 Meteorological Condition

Temperature measurement should be 5 °C ~ 35 °C, atmospheric pressure 100kPa ~ 105kPa, relative humidity of 30% to 75%, from the ground 1.2m height

Wind speed is not greater than 3m/s of no rain, no fog, no dew crop surface under conditions.

3.2 Test Conditions

Length of paddy test be not less than 100m, a width of not less than 8 times the working width detected by paddy soil at a depth of 7.5cm

Firmness should not be less than 350kPa. There should be no ridge without clods or stones larger than 5cm, field longitudinal slope and transverse slope should not exceed

0.1%.

3.3 Crops

Detection of the crop should be ripe stage, should be no more than 20cm from the surface of weeds, crop-free lodging, density and degree of growing evenly. Rice

Natural height of about 90cm ± 10cm, ear width is not more than 250mm, grain moisture content of 18% to 25%, a water content of 35% to straw

55% yield was 7500kg/hm2 ~ 8250kg/hm2.

3.4 prototype status

3.4.1

harvester measured shall comply with GB/T 20790 and consistent with random technical documents, maintaining the normal state of the art.

Fuel 3.4.2 shall be measured with No. 0 diesel. Repeated measurements should use the same batch of fuel.

3.4.3

measured harvesters should maintain maximum design total mass. Car occupants (including the driver) shall comply with the number of random technical documents,

It can be used instead of the occupant weight placed in the appropriate position, press 75kg per meter (upper seat 65kg, front floor 10kg).

3.4.4

should be emptied before each test barn.

3.4.5

before measuring, the measured harvester should be preheated, so that all parts reach normal operating temperature. Xie Xie organic food means, grain harvester

Gyeonggi should fill grain (grain tank auger cover, the vertical height should not exceed 10cm).
