Efficient fertilizing device

The efficient fertilizing device comprises a machine body, a material mixing barrel is fixedly installed at the bottom of an inner cavity of the machine body, a feeding port is formed in the right side of the top of the material mixing barrel, and wheels are fixedly installed at the four corners of the bottom of the machine body. The device comprises a machine body, a mixing barrel, a feeding hole, a protective shell, a first motor, a first screw rod, a first sliding block, a lifting plate, a first limiting rod, a first limiting block, a first limiting ring, a second motor, a rotating rod, a stirring blade, a wall scraper, a water pump, a spray head, a fixed column, a third motor, a second screw rod, a second sliding block, a second limiting block, a second limiting rod, a second limiting ring and wheels. Through cooperative use of a telescopic rod, a frame, ploughing thorns, a rotating wheel, a third limiting block and a water inlet pipe, the problems that the existing fertilization area is small, the fertil
