In the production research work, due to the restriction of corn growth conditions, a large amount of work needs to rely on the judgment of the external features such as form, color, texture, and so on. The extraction of this information needs to rely on manual measurement, so related tools are also very necessary. However, some simple measurement tools have a large workload, are cumbersome, subjective, and difficult to verify measurement data, and some feature values ​​are difficult to quantify and describe, which seriously restricts the promotion of advanced production technology in corn science research and production. Therefore, more and more studies have applied digital image processing techniques to the corn planting process to solve the issue of extracting corn characteristic information. Automatic corn tester is a commonly used instrument in current work. WeChat sweep to get more professional information: Loader Bucket, loader arm, rocker arm, Loader Linkage Rod cylinder, need to be connected by the loader pin shaft, in order to reduce wear, hole installation bushing, pin shaft material is the best choice of 42CrMo, consider the price of 45 steel, both choose 40Cr, do conditioning treatment HB250 to 300 is ok, of course, about 300 strength is better, Machining is more difficult. If the shaft surface is to withstand some wear resistance, it must be medium frequency surface hardening or hard chrome plating. My company for many heavy industry enterprises supporting excavator pin shaft, diameter is 50-135mm, each company designated material is also different, roughly 45 steel, 40Cr steel and 42CrMo. 42CrMo is used for important parts with large bearing capacity. Heat treatment process is not described, it is too simple for professional heat treatment manufacturers.

The technique of using computer image processing technology to quickly and accurately extract the outline of maize seeds has made preliminary preparations for the evaluation of corn seed level. According to the outline of corn seed shape, we can further identify the corn seed size, style, matching, etc., so as to provide an effective method for the classification of corn seed level.
Based on the existing research experience, a tentative study was made on the application of digital image processing technology in corn test. In the outdoor examination of corn, a large amount of plant data needs to be measured in the field, the tools are relatively simple, and the manual reading error is large. The indoor test work, the workload is large, time-consuming and laborious, prone to error. Therefore, the application of the automatic corn tester alleviates these two deficiencies and is more convenient and quicker.
In summary, the automatic maize seed tester has a wide range of applications in the corn field. However, there are few mature products based on image processing technology that can be applied directly to the production practice, and most of them remain in the laboratory test phase. Therefore, the productization of research results will be an important direction of development.
