3.1 Meteorological Condition

Temperature measurement should be 5 °C ~ 35 °C, atmospheric pressure 95kPa ~ 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

Rice (wheat) field test area should not be less than the length of 100m, a width of not less than 8 times the working width. Detecting paddy 7.5cm depth

Soil firmness should not be less than 350kPa, wheat field not less than 500kPa; 15cm ~ 20cm of the soil compactness should not be less than 7.5cm at Kennedy

Solidity. There should be no ridge and no more than 5cm clods or stones, fields, longitudinal slope and transverse slope should not exceed 0.3%.

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. wheat

Natural height 80cm ± 10cm, Grass Valley ratio of 0.8 to 1.0, the grain moisture content of 12% to 20%, straw moisture content of 20% to 30% yield

An amount of 5250kg/hm2 ~ 6750kg/hm2. Rice natural height 90cm ± 10cm, Grass Valley ratio of 1.5 to 1.9 and a moisture content of grain

18% to 25%, straw moisture content of 35% to 55%, a yield of 7500kg/hm2 ~ 8250kg/hm2.

Wheel wheat combine harvester income test; crawler rice combine harvesters income test.

3.4 prototype status

3.4.1

harvester measured shall comply with JB/T 5117 and consistent with the random technical documents, maintaining the normal state of the art.

3.4.2

Fuel measurement should be 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.
