[0028] Beneficial effects

[0029] Compared with the prior art, the advantages of the present invention are:

[0030] (1) In this scheme, when feeding is required, the granular raw materials are first put into the feed hopper through external transportation equipment, and then the output end of the servo motor is started to reverse, and the second rotating rod on the upper side is reversed by the output end of the servo motor, and the second rotating rod on the upper side is rotated to drive one of the synchronous wheels to rotate, and the transmission cooperation between the synchronous wheel and the synchronous belt drives the other synchronous wheel to rotate, so as to drive the first rotating rod to rotate through the other synchronous wheel, and the rotation of the first rotating rod drives the notched rotating wheel to rotate, and the rotation of the notched rotating wheel drives the connecting rod and the push rod to rotate, and the groove wheel is driven to rotate by the rotation of the push rod.
