9. The environment-friendly raw material weighing system for concrete production according to claim 8, wherein: the output shaft of the linear motor (34) is fixedly connected with a mounting plate (341), and the driving motor (2121) is fixedly connected to the mounting plate (341).
10. A concrete preparation process is characterized by comprising the following steps: the method comprises the following steps:
the method comprises the following steps: starting a driving motor (2121), driving the auger (211) to rotate through a bevel gear (2122), enabling the auger (211) to rotate, conveying the raw materials in the storage bin (22), discharging the raw materials from a discharge hole (221), and dropping the raw materials into an inner container (36) in a weighing hopper (32) for weighing;
step two: the pressure sensor (37) detects the weight of the raw material on the inner container (36), and when the weight reaches a preset value, the pressure sensor (37) drives the linear motor (34) and the rotary motor (311) to start through the processor;
step three: after the linear motor (34) is started, the output shaft is shortened to be separated from the bottom of the weighing hopper (32), one end of the weighing hopper (32) is rotatably connected with the rack body (1), the other end of the weighing hopper (32) is downwards inclined and supported by a spring (35), and raw materials in the inner container (36) are poured downwards;
step four: meanwhile, the linear motor (34) drives the mounting plate (341) and the driving motor (2121) to move downwards, the two groups of bevel gears (2122) are separated, and the auger (211) stops conveying raw materials;
step five: after the rotating motor (311) is started, the cam (312) is driven to rotate, the protruding part of the cam (312) is movably abutted to the bottom of the weighing hopper (32), so that the weighing hopper (32) can be impacted to vibrate, the pouring of the raw materials in the liner (36) can be accelerated, and the pouring is more complete.
