GB/T 8097 harvesting machine combine harvester test method
3 job quality indicators
3.1 Working conditions
The conditions of the working plots should meet the agricultural technical requirements for mechanical harvesting operations, and soybean combined harvesting should be carried out in time for the soybean maturity.
Soybeans do not fall, and the grain moisture content is between 13% and 15%.
3.2 Quality indicators
When the operating conditions are in accordance with the provisions of 3.1, the quality of soybean combined harvesting machinery operations shall comply with the requirements of Table 1.
Table 1 Quality indicators of soybean combined harvesting machinery
Serial number item quality index
1 Total loss rate/(%) ≤ 3
2 impurity ratio/(%) ≤ 5
3 breaking rate/(%) ≤ 5
4 job quality testing methods
4.1 Total loss rate
After harvesting, the plots are taken at five points according to the five-point method, and each point is drawn along the advance direction of the combine harvester by a length of 1 m (the cut width is greater than
At 2m, the length is 0.5m), the width is the sampling area of the working width of the machine, and all the seeds and pods are collected in the sampling area to get all
The lost beans are weighed and converted into soybean losses per square meter. Based on the quality of the harvested soybeans and the corresponding harvested area
Calculate the amount of soybeans per square meter. Calculate the total loss rate according to equation (1).
Ps= WssWsh+Wss×
100% (1)
In the formula.
Ps---total loss rate;
Wss---the amount of soybean loss per square meter, in grams per square meter (g/m2);
Wsh---the amount of soybeans per square meter, in grams per square meter (g/m2).
The average value of the total loss rate of the five measurement points was obtained as a quality index.
4.2 impurity content
Five samples were randomly selected from the harvested seeds of the combine harvester, and each batch was not less than.2000 g. Soybean sample obtained
