The method of using the shear-type mixing machine based on the blueberry cultivation mixed substrate as described in claim 7, characterized in that: S1: In its natural state, the mixing cylinder (32) is in a vertical position. First, open the first sealing cap (342) at the top of the first feed pipe (341) and put the coarse material for the blueberry cultivation mixed substrate into the mixing cylinder (32) through the first feed pipe (341) for mixing and crushing. At this time, due to the action of the limiting mechanism (46), the mixing cylinder (32) itself cannot rotate. Next, power is supplied to the first motor (355) located on the back of the L-shaped support (31). With the start of the first motor (355) drive shaft, it drives the stirring shaft (352) to rotate synchronously. The stirring shaft (352) is equipped with multiple stirring blades (353).

S3: Then, while ensuring that the outer surface of the mixing drum (32) is in close contact with the rubber wheel (482), the second motor (485) is turned on. This motor drives the transmission gear (484) to rotate, and then drives the entire mixing drum (32) to rotate around the stirring shaft (352) through meshing with the gear ring (41). In addition, before the mixing drum (32) starts to rotate, the second sealing cap (344) at the end of the second feed pipe (343) is opened so that lightweight materials such as perlite can be added to it. During the continuous rotation of the mixing drum (32), the lifting plate (354) can quickly turn the material.
