Abstract
With the continuous development of modern agricultural technology, deep loosening
fertilization technology has become an important means to improve soil quality and improve
crop yield. As the key equipment to realize this technology, the structural design of the machine
directly affects the performance and effect of the machinery. In northeast China, there are many
types of crop planting modes, and the requirements for row spacing are slightly different. The
traditional deep loosening fertilization machines are mostly equal row spacing design, which
cannot meet the agronomic requirements of all farming modes.
According to the wide and narrow row planting mode of corn in northeast China, a deep
loosening fertilization machine is designed to meet its agronomic requirements to improve the
work efficiency, practicability and stability of fertilization. Firstly, through the analysis of the
structural characteristics and working principle of the wide and narrow row deep loosening
fertilization machine, the design scheme of the whole machine is determined. Then, the structure
was designed through theoretical calculation analysis and three-dimensional modeling. Finally,
EDEM simulation software is used to simulate the soil tillage of the deep pine shovel, and to
conduct the static stress analysis based on the simulation results. After the design, the deep
loosening fertilization machine is a multi-functional machine that integrates deep loosening,
stubble cutting, fertilization and suppression, which can effectively reduce the number of deep
loosening fertilization machine and reduce the operation cost on the basis of meeting the
agronomic requirements of wide and narrow planting mode.
