The terrain should be flat and free of obstacles. The absolute soil water content should not be greater than %. The length of the test area should not be less than 5 meters, and the width should not be less than 2 times the width of the operating area. 51. If the following conditions occur during the test, the test shall be interrupted: During the test operation of the machine, all parts are not able to rotate quickly, and the machine is stuck, resulting in failure to operate normally. 6) During the test, the machine has a problem with the performance test and cannot work normally: 5.2 Technical characteristics measurement
Before the test, the technical characteristics of the prototype should be measured. The measurement should be carried out on a level and solid ground: 53 Test site survey
5.3.1 Determine the test area and terrain conditions. Take 5 points along the line in the test area. The moisture content, filling solidity and other parameters should be measured. The method of measurement should be in accordance with CBT52.
5.3.2 Determine the growth condition of crops, height, row spacing, standard, bedding and beauty, heat dissipation and density. The measurement method should be in accordance with CBT52.
53.3 Take 5 points diagonally in the test area to determine the width, depth and density of the plot. The width and depth should be measured at 5 rows (rows) at each point. On the same scale (line), the test blocks with a width of 2m are weighed and the length of the blocks is measured. At the same time, the length, size and weight of each block in the area are measured. 5.4 Performance test 54.1 Determination of performance indicators of the bell control machine 5.4.1.1 The test area consists of a stable area, a stable area and a test area. The length of the stable area is 10m1, and the length of the stable area is 2C. After the stable area is pulled, it should be connected with the body of the vehicle. The performance test is carried out in the test area. 5.4.1.2 The number of round trips in each test area should be no less than ~, and the machine should not change its working condition in the test area. 5.4. 1. 3 Determination of the productivity of each stroke in a year shall be calculated according to the formula: 11, and the average value shall be calculated after heating, = 0,0001-/

5.2.1.4 The principle of determination: After the machine has worked for a stroke, collect the measured pieces and weigh them. 5.4.1.5 Determination of loss quality: a) Determination of loss quantity: after the whole is collected, the damaged pieces which are controlled by the machine are found out and weighed. b) Determination of mixed excavation: after the collection and burial, the remaining pieces which can be dug out by the machine are found out manually (for the damaged pieces, they need to be separated), and weighed. The sum of the loss quantity and the damaged quantity is taken as the basis for loss. 5.4.1.7 Determination of loss of H: The loss of H shall be calculated according to formula (2) and formula (3): W = W × 1G3

5. 4. 2. 2
Determination of the weight of damaged parts:
Determination of the quality of the plate: After the prototype is processed in a process, the pieces that have not been dug out but not yet made shall be taken out and weighed. Determination of the quality of the dug products: Use .1 to find out the pieces that have not been damaged (the damaged pieces shall be separated) and weigh them. 5
The sum of the leakage amount is the alarm: 5.4.2.3 The measurement of harvested potatoes is: the prototype machine makes a trip: the method is to weigh the scale, 5. 4. 2. 4
The measurement of impurity amount: after the prototype machine works for one trip, collect the impurities in the box and weigh them. The measurement of general defects: from the picker, collect all the damaged ones and weigh them. 5. 4.2. 5
The loss rate and injury rate, including the impurity rate, are calculated by the formula (4) and formula (3), 5 4.2.63
