The utility model relates to the technical field of agricultural
sowing, in particular to a
sowing and planting all-in-one
machine which comprises a
machine body, a storage box arranged on the
machine body and a conveying
pipe arranged on the storage box, a connecting plate is movably arranged on the storage box, a through groove is formed in the connecting plate, seeds are conveyed in the conveying
pipe, a bottom plate is arranged in the storage box, and the bottom plate is arranged in the storage box. According to the
sowing and planting all-in-one machine, when the arranged circular grooves are filled with seeds in the storage box, the adjusting
assembly moves, the seeds in each circular groove can enter the corresponding circular groove to form a
single compartment, and at the moment, the seeds in the circular grooves can be separated from the storage box through the adjusting
assembly. The seeds in the previous compartment can be communicated with the next circular groove along with rotation, the seeds protruding out of the compartment can be squeezed back into the storage box, the seeds enter the storage box again when the next circular groove arrives, the multiple compartments can keep the same seed size before reaching the through groove, the gap is reduced as much as possible, and the seed
storage efficiency is improved. Therefore, the number of the seeds falling each time can be accurately controlled.
