[0004] The above-mentioned device stirs the fertilizer in the center and on the inner wall of the agitator body in steps, that is, the fertilizer in the center of the agitator body is stirred first, and then the second motor is started to move the stirring paddle position, and then the fertilizer adhered to the inner wall of the agitator body is stirred. There is a problem of low stirring efficiency. More importantly, this method of moving the stirring paddle cannot fully stir the inner wall of the agitator body, and there is a stirring dead angle, and then there is a problem of poor stirring effect. In addition, the above-mentioned device drives the relevant components through the third motor to finally realize the tilting of the entire agitator body to increase the discharge speed of the fertilizer after stirring. Not only does the whole process have many operating steps, but there is also a problem of poor stability performance due to the tilting of the agitator body. In addition, after the tilting, the fertilizer in the agitator body is still discharged by gravity, and there is a problem of slow discharge speed. Utility Model Content
