Description

Technical Field

[0002] For wheat and other grain crops, the yield of the field is calculated, that is, the yield is measured. Generally, the yield measurement test only needs to harvest 1-5m 2 In order to measure the yield in a small area, it is usually done by manual harvesting, threshing with a medium-sized wheat thresher, and then weighing to measure the yield. In this process, wheat grains are easy to fall or mix, and the process is complicated and labor-intensive. The traditional manual yield measurement method wastes manpower, takes a long time, and the measured yield may have large errors.

[0003] Various small and medium-sized harvesters can also be used to harvest wheat, but for yield measurement in experimental fields and small areas with small planting areas, large-scale harvesting is not required. It is only necessary to randomly measure the yield of a small area in different areas of the experimental field and repeat the yield measurement work on different plots. In this way, the use of commonly used harvesters on the market seems to be not worth the cost. Even with a small harvester, it is too bulky and inconvenient to use, which affects the efficiency of wheat yield measurement. Summary of the invention
