As a design of the automatic feeding device for a plug seedling production line of the utility model: the horizontal screw conveyor includes notched spiral blades and full-edge spiral blades; the notched spiral blades and the full-edge spiral blades are fixed on the pusher shaft, One end of the pushing shaft is connected with the reduction motor, and the middle is fixedly installed on the hopper through a support bearing, and the other end is suspended in the air.

As a design of the automatic feeding device for a plug seedling production line of the present utility model: the longitudinal screw conveyor includes a feeder casing and a longitudinal conveying screw; one end of the longitudinal conveying screw is installed on the feeder casing through a bearing, and the other end Connected with the feeding motor.

As a design of an automatic feeding device for a plug seedling production line of the present invention: the spreader includes a stirrer and a spreader box; the stirrer is installed on the spreader box through a bearing with a seat and is connected to the spreader motor.

The utility model has the following advantages:

(1) The device occupies a small area, has high production efficiency, simple operation and strong adaptability;

(2) The speed of the agitator is adjustable, so that the filling is uniform and smooth;

(3) The excess material soil is directly dropped into the material box, and the transportation and recycling are integrated, which avoids the waste of raw materials such as matrix or mixed soil.
