Linkage type double-box sowing and fertilizing integrated device

The utility model discloses a linkage type double-box type seeding and fertilizing integrated device, which relates to the technical field of seed seeding and comprises a connecting frame and a clutch device, the connecting frame is fixedly mounted above a tractor, and a first box mechanism and a second box mechanism are fixedly mounted at two ends of the upper side of the connecting frame respectively. The double-chain-wheel group is driven to rotate by the wheel shaft of the walking tractor through transmission, so that seeds and fertilizers in the first box body mechanism and the second box body mechanism are quantitatively discharged through the plurality of groups of seed discharging assemblies and then are sown into soil, the device is driven to sow through the moving power of the walking tractor, and the linkage of moving and sowing is realized; extra power is saved, energy loss is reduced, and the seeding speed is directly proportional to the moving speed of the walking tractor, so that seeding is mor
