S3. Various raw materials are supplied to the interior of the mixing device 3 through the positioning chute 22 and the material discharge conduit 213. The connecting motor 35 can drive the fixed gear ring 36 and the stirring blade 33 through the transmission gear 37 to mix the various raw materials to complete the preliminary preparation operation.

Working principle: The user can position the external feed tube to the upper part of the multi-group weighing device 1, and then transport the corresponding weight portions of biomass fertilizer, calcium silicate powder, humic acid, water lock agent, chitosan, magnesium sulfate, brassinolide and bentonite and other raw materials to the upper part of the weighing device 1 for weighing. During weighing, the guide chute 17 can carry the raw materials, and at the same time, the four groups of spring retaining rings 12 at the bottom can directly react the elastic force of the load to the upper part of the weight sensor 13. The four groups of weight sensors 13 can accurately calculate the weight. When the weight measured by the multi-group weighing device 1 is qualified, the servo motor 23 can drive the transmission guide shaft. 25 is rotated. When the transmission guide shaft 25 rotates, it can drive the toothed belt wheel 210 at the front to rotate, and the toothed belt wheel 210 can drive another set of transmission gears 212 to rotate through the toothed belt 211, so that the transmission gear 212 can drive the transmission guide shaft 25 to rotate in the same speed and in the opposite direction, so that the two sets of transmission guide shafts 25 can drive the weighing device 1 to flip into the positioning chute 22 through the limiting sleeve 15, so that the raw materials can be introduced into the interior of the mixing device 3 through the positioning chute 22, and the mixing device 3 can fully mix the raw materials, thereby maximizing the efficiency of raw material processing.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
