Pit digging machine with backfilling function for restoring planting of mangrove forest

The invention is applicable to the technical field of planting, and provides a mangrove forest planting recovery pit digging machine with a backfilling function, comprising: a vehicle body, on which a plurality of intermittent driving wheels are arranged; the pit digging mechanism is arranged in the vehicle body and used for digging pits in the land and pushing soil in the pits to the periphery; the telescopic planting pipe is arranged in the pit digging mechanism; the backfilling mechanism is arranged in the vehicle body, and the backfilling mechanism is used for pushing the soil pushed away by the pit digging mechanism back into the soil pit after the saplings are planted into the soil pit and smoothing the soil. When the soil pit digging machine with the backfilling function for restoring planting of the mangrove forest is used, the intermittent driving wheel intermittently drives the vehicle body to move forwards, when the vehicle body is in a static state, the pit digging mechanism digs a pit below, at t
