Material sowing machine with automatic feeding function

The utility model belongs to the field of agricultural mechanical equipment, and particularly relates to a material sowing machine with an automatic feeding function, which comprises a material sowing machine main body carrier dragged by a tractor, a material box mounted on the material sowing machine main body carrier, and a feeding device. The feeding device comprises a motor, a lift car, a lift car baffle, a rotating shaft support, a rotating shaft, a winch and a traction rope. The motor drives the winch to rotate, the traction rope pulls the lift car to move upwards, and when the lift car ascends to the opening range of the feeding port of the material box, materials such as bio-organic fertilizer enter the feeding port through the inclined plate of the lift car and the inclined lift car door under the action of gravity, so that the materials enter the material box. The automatic lifting and releasing device can automatically lift and release materials such as bio-organic fertilizer, does not need to lift
