Mechanical rice seedling culture soil taking machine and soil taking method

The invention discloses a mechanical rice seedling culture soil taking machine and a soil taking method. At present, seedling culture soil is commonly collected in the field, and during soil taking, manual scattered digging and collecting are commonly adopted; and through the manner, normal usage of the existing field is not damaged, but efficiency is low, and expense is high. Existing extractionequipment such as an excavator is high in efficiency, but flatness of the field is likely to be damaged, and the field planting work is influenced. The mechanical rice seedling culture soil taking machine comprises a rapid suspension frame welding combination (1), a lower suspension assembly (2), an upper suspension welding combination (3), a front auxiliary beam welding combination (4), a main frame welding combination (5), a seal plate welding combination (6) and connecting rod mechanisms. The upper suspension welding combination, the lower suspension assembly and a soil taking shovel welding combination (20) are se
