Description

Green manure intercropping sowing structure with adjustable row spacing Technical Field The utility model provides a green manure interplanting seeding structure, and particularly relates to a green manure interplanting seeding structure with adjustable row spacing. Background The green manure interplanting seeding device is a mechanical device for seeding green manure crops among existing crop rows in agricultural production, and has the main functions of improving land utilization rate, improving soil structure, increasing soil fertility and promoting cooperative growth between crops and green manure. Conventional green manure interplanting devices generally include a seed storage device, a sowing mechanism, a power system, and other basic components, which meet the basic requirements of green manure sowing to some extent, but suffer from a number of disadvantages. Most green manure interplanting seeding devices in the prior art are simple in structure, and the row spacing cannot be easily adjusted once being determined, so that the green manure interplanting seeding device cannot adapt to diversified planting requirements under different crop interplanting modes. In addition, the seed throwing mode is comparatively single, is difficult to realize accurate intermittent type nature batch feeding, leads to seeding homogeneity and precision not enough, influences the growth effect of green manure and the overall benefit of intercropping system. Moreover, the mechanical connection structure of the existing device is poor in stability, is difficult to adapt to complex and changeable field operation environments, is easy to loose or damage parts, and causes mechanical damage to green manure. Disclosure of utility model The application aims to solve the problems, and solves the problems of fixed row spacing, inaccurate seed throwing and unstable mechanical connection in the prior art by providing the green manure interplanting sowing structure with the adjustable row spacing, thereby realizing accurate and flexible green manure interplanting sowing.
