Description

technical field [0001] The invention relates to agricultural measurement and control technology, in particular to a small seed dynamic tracking self-adaptive reseeding measurement and control device and method suitable for sowing operations. Background technique [0002] my country has a wide variety of small-sized seed crops, a wide range of planting areas, and a continuous increase in industrial value. It has an important position in crop planting in my country and has a very broad development prospect. The sowing of small-sized seeds is the main process of planting. In the process of ensuring that the operation progress of the fertilizing and seeding machine is matched, the reseeds should be replanted with high efficiency and low loss, and the seeds should be transported one by one to the various seed boxes of the fertilizing and seeding machine. , which can effectively improve the work process of sowing and fertilization, and ensure its efficient and continuous normal wo...

AI Technical Summary

Problems solved by technology

[0003] At present, scholars have done a lot of research on fertilization and seeding, and achieved good results, but there is little research on the dynamic tracking and replanting of small seeds. Basically, manual or semi-mechanized methods are used, which are difficult to match the progress of sowing and fertilization machines. It affects the process of fertilization and seeding, and there are problems such as low production efficiency, high labor intensity, and high operating costs, and its low degree of mechanization has become an urgent problem that restricts the industrialization of small-size seed crops.

[0004] At present, the reseeding device mainly relies on manual experience to adjust the working parameters of the corresponding mechanism, which has low accuracy and real-time performance. In addition, due to the inability to detect the actual working parameters of the reseeding device in real time, the adjustment amount of the drive motor cannot be accurately grasped. It is impossible to establish a feedback-based automatic adjustment device for replanting working parameters, and the degree of automation of replanting is low
