[0027] Working principle: When the present invention is used, baking soda is first placed in the preparation tank 1, the acetic acid solution is placed in the placement box 13, and finally the configured anaerobic culture medium is added to the culture tank 2, and the configured anaerobic culture medium reaches two-thirds of the culture tank 2; and the preparation tank 1 and the culture tank 2 are connected by a connector 1; Then, the micro motor 21 is started, so that the output shaft of the micro motor 21 rotates counterclockwise, thereby driving the short shaft 29 and the gear 2 28 to rotate counterclockwise, thereby driving the gear 1 27 and the hollow shaft 25 to rotate counterclockwise, and further driving the circular plate 22 and the stirring blade 26 to rotate counterclockwise; Then, under the cooperation between the triangular clamping block 33 and the annular groove 34, the short cylinder 15 is clamped in the annular groove 34, thereby driving the short cylinder 15 to rotate, so that the annular plate 7 and the connecting rod 18 move back and forth, and further driving the piston 23 to move back and forth; When the piston 23 moves toward the end close to the micro motor 21, the pressure in the sealed box 14 increases, causing the acetic acid solution in the placement box 13 to fall on the triangular filter plate 38 through the liquid guide tube 12, so as to filter the sediment in the acetic acid solution. The filtered acetic acid solution falls on the bottom of the filter box 20, and then the acetic acid solution enters the sealed box 14 through the liquid inlet pipe 19; and when the piston 23 moves toward the end away from the micro motor 21, the acetic acid solution in the sealed box 14 is transported to the annular box 24 through the liquid outlet pipe 10, and then the acetic acid solution enters the hollow shaft 25 through the liquid inlet hole 30, and finally the acetic acid solution falls from the bottom of the hollow shaft 25 into the preparation tank 1; The acetic acid solution falling into the preparation tank 1 will react with baking soda to produce carbon dioxide gas; and the hollow shaft 25 will drive the stirring blade 26 to rotate when rotating, so as to stir the acetic acid solution and baking soda, so as to quickly prepare carbon dioxide gas, thereby facilitating the preparation of microbial seed liquid; When the circular plate 22 rotates counterclockwise, it drives the stopper 31 to rotate. When the stopper 31 contacts the movable rod 44, the movable rod 44 rotates, so that the movable rod 44 does not move. When the stopper 31 is separated from the movable rod 44, the movable rod 44 is reset under the action of the torsion spring shaft. Then the carbon dioxide gas produced in the preparation tank 1 will enter the regulating valve 15 through the air guide pipe 6, and then the carbon dioxide gas will enter the bottom of the culture tank 2 through the air guide pipe 17, so that the carbon dioxide gas is mixed with the configured anaerobic culture medium, so as to facilitate the preparation of the microbial seed liquid; when bubbles continue to be generated in the culture tank 2, turn off the regulating valve 15, unplug the air guide pipe 6, and then place the culture tank 2 in the incubator for culture at a suitable temperature; Then, the output shaft of the micro motor 21 is rotated clockwise. At this time, when the triangular clamping block 33 contacts the triangular clamping groove 35, the triangular clamping block 33 enters the rectangular cavity, so that the short cylinder 1 5 does not rotate with the circular plate 22; at the same time, when the circular plate 22 rotates clockwise, the stopper 31 is rotated, and then under the action of the limit plate 45, the stopper 31 contacts the movable rod 44, and the movable rod 44 cannot rotate. Then, as the stopper 31 rotates, the movable rod 44 moves, thereby driving the connecting rod 2 41 to move; Since the second short cylinder 43 moves in the cleaning groove 3901, the scraper 40 contacts the triangular filter screen 38, and the scraper 40 moves with the movement of the second connecting rod 41, so as to clean the sediment on the triangular filter screen 38, and then push the cleaned sediment into the garbage recovery net box 37 to collect the sediment; When the short cylinder 43 moves to the end of the cleaning groove 3901, the scraper 40 moves upward under the action of the extrusion spring 32, and the short cylinder 43 enters one of the inclined grooves 3903; and when the stopper 31 is separated from the movable rod 44, the scraper 40 is reset under the action of the reset spring 42; then the short cylinder 43 is reset from the return groove 3902, so that the scraper 40 is separated from the triangular filter plate 38, so as to prevent the sediment on the triangular filter plate 38 from being brought back; and when When the short cylinder 2 43 moves into another inclined groove 3903, under the action of gravity of the scraper 40, the short cylinder 2 43 moves into another inclined groove 3903, and then the scraper 40 moves with the movement of the connecting rod 2 41. At this time, the short cylinder 2 43 moves downward and enters the cleaning groove 3901, so that the extrusion spring 1 32 is compressed; through the reciprocating movement of the scraper 40, the sediment on the triangular filter plate 38 is pushed into the garbage recovery net box 37, thereby realizing the collection of the sediment.
