[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention cooperates with structures such as a servo motor and a dosing cartridge so that when the servo motor is started, the device can drive the dosing cartridge to rotate and then drive the stirring rod to rotate to mix the carbon source, nitrogen source and phosphorus source inside the device. The user can add biological nutrients to the inside of the dosing cartridge through the dosing port, and by starting the second electromagnet and the first electromagnet, the gear lever moves up to break away from the blockage of the hole.

[0025] like Figures 1 to 6 As shown, the stirring and dosing mechanism 7 includes a dosing cartridge 701, a dosing port 702 and a stirring rod 703. The dosing cartridge 701 is fixed to the bottom end of the servo motor 6. The top of the dosing cartridge 701 is provided with a dosing port 702. The outside of the dosing cartridge 701 is fixed with a stirring rod 703. The top of the inside of the dosing cartridge 701 is fixed with an inner sleeve 704. The dosing cartridge 701 and the top of the shell 1 are movably connected. Several groups of stirring rods 703 are provided. The stirring rods 703 are evenly spaced about the central axis of the dosing cartridge 701. The inner sleeve 704 is provided with a mounting groove.

[0026] like Figures 1 to 6 As shown, a shift rod 705 is movably connected to the bottom end of the inner sleeve 704, a first electromagnet 706 is fixed to the top end of the shift rod 705, a second electromagnet 707 is fixed to the top end of the inner sleeve 704, a return spring 708 is fixed to the top end of the shift rod 705, the outer wall of the shift rod 705 is close to the inner wall of the inner sleeve 704, the shift rod 705 and the inner sleeve 704 are slidably connected, the return spring 708 is used to squeeze the shift rod 705 and keep it moving downward, and a partition is arranged between the dosing chamber 709 and the inner cavity of the dosing cartridge 701.

[0027] like Figures 1 to 6 As shown, a dosing chamber 709 is provided at the bottom end of the dosing cartridge 701, a dosing hole 710 is provided on the outside of the dosing cartridge 701, a first connecting rod 711 is movably connected to the bottom end of the dosing cartridge 701, an inclined fan blade 712 is fixed to the top end of the first connecting rod 711, a straight fan blade 713 is fixed to the bottom end of the first connecting rod 711, a plurality of groups of dosing holes 710 are provided, and the dosing holes 710 are evenly spaced about the central axis of the dosing cartridge 701, an outer wall of the first connecting rod 711 is close to the inner wall of the dosing cartridge 701, the dosing cartridge 701 and the first connecting rod 711 are movably connected, and the inclined fan blades 712 and the straight fan blades 713 are symmetrically distributed about the central axis of the first connecting rod 711.

[0028] The above scheme is adopted: by adding biological nutrients into the inside of the dosing cartridge 701, and by starting the second electromagnet 707 and the first electromagnet 706, the gear lever 705 moves up to break away from the blockage of the hole, at this time, the medicine can enter the inside of the dosing bin 709 and be discharged through the medicine discharge hole 710, after the dosing is completed, the second electromagnet 707 and the first electromagnet 706 are powered off so that they are no longer attracted, and the reset spring 708 can squeeze the gear lever 705 downward to reset and re-block the hole to stop adding the biological nutrients, and when the medicine enters the inside of the dosing bin 709 and is ready to be added through the medicine discharge hole 710, since at this time there is a medium inside the dosing bin 709 and inside the shell 1 Therefore, when the dosing cartridge 701 rotates, the straight blades 713 and the oblique blades 712 are subjected to resistance at the same time. Since the pressure borne by the straight blades 713 is greater than that of the oblique blades 712, the straight blades 713, the oblique blades 712 and the first connecting rod 711 are in a prohibited state compared to the shell 1. At this time, the biological nutrient inside the dosing bin 709 rotates along with the rotation of the dosing cartridge 701, thereby generating centrifugal force to be thrown out of the dosing bin 709. At this time, the biological nutrient can be guided by the shape of the oblique blades 712, thereby accelerating the rate of adding the biological nutrient, and the biological nutrient to be added and the total amount can be added separately, so that the mixing state of the carbon source, nitrogen source and phosphorus source can be better observed.

[0029] like Figures 1 to 8 As shown, the scraping mechanism 8 includes a discharge port 801, a solenoid valve 802 and a sleeve disc 803. The discharge port 801 is installed at the bottom end of the shell 1, and the solenoid valve 802 is arranged outside the discharge port 801. The top of the discharge port 801 is movably connected with the sleeve disc 803, and a scraping plate 804 is fixed outside the sleeve disc 803. The top of the discharge port 801 is connected to the shell 1, and the outer wall of the sleeve disc 803 is close to the inner wall of the discharge port 801. The discharge port 801 and the sleeve disc 803 are rotatably connected. The scraping plates 804 are arranged in several groups, and the scraping plates 804 are symmetrically distributed about the central axis of the sleeve disc 803.

[0030] like Figures 1 to 8 As shown, a second connecting rod 805 is fixed inside the sleeve 803, and a transmission fan blade 806 is fixed to the bottom end of the second connecting rod 805. Four groups of second connecting rods 805 are arranged at equal intervals about the central axis of the sleeve 803. Several groups of blades are arranged on the outer wall of the transmission fan blade 806, and the blades are distributed at equal intervals about the central axis of the transmission fan blade 806.

[0031] The above scheme is adopted: by opening the solenoid valve 802, the channel of the discharge port 801 is not blocked, and the mixed solvent is discharged through the discharge port 801. When passing through the transmission blade 806, the shape of the transmission blade 806 can drive the transmission blade 806 to rotate, and then the rotation of the transmission blade 806 drives the second connecting rod 805, the sleeve 803 and the scraper plate 804 to rotate, so that the scraper plate 804 can scrape the bottom end of the inside of the shell 1 when it rotates.

[0032] The working principle and use process of the present invention are as follows: when the servo motor 6 is started, the dosing cartridge 701 is driven to rotate, and then the stirring rod 703 is driven to rotate to mix the carbon source, nitrogen source and phosphorus source inside the device. The user can add biological nutrients to the inside of the dosing cartridge 701 through the dosing port 702, and by starting the second electromagnet 707 and the first electromagnet 706, the gear lever 705 moves up to break away from the blockage of the hole. At this time, the medicine can enter the inside of the dosing chamber 709 and be discharged through the medicine discharge hole 710. After the dosing is completed, the second electromagnet 707 and the first electromagnet 706 are turned on. The first electromagnet 706 is powered off so that it no longer attracts. At this time, the reset spring 708 can squeeze the gear lever 705 downward to reset it and block the hole again to stop adding the biological nutrient. After the nutrient enters the dosing bin 709 and is ready to be added through the discharge hole 710, since there is medium in both the dosing bin 709 and the shell 1 at this time, when the dosing cartridge 701 rotates, the straight blades 713 and the inclined blades 712 are simultaneously subjected to resistance. Since the pressure on the straight blades 713 is greater than that on the inclined blades 712, the straight blades The blades 713, the oblique blades 712 and the first connecting rod 711 are in a prohibited state compared to the shell 1. At this time, the biological nutrient inside the dosing bin 709 rotates along with the rotation of the dosing cartridge 701, thereby generating centrifugal force to throw it out of the dosing bin 709. At this time, the biological nutrient can be guided by the shape of the oblique blades 712, thereby accelerating the rate of adding the biological nutrient, and separating the biological nutrient to be added from the total amount, so that the mixing state of the carbon source, nitrogen source and phosphorus source can be better observed, and the processed carbon source, nitrogen source and phosphorus source can be better observed. When the phosphorus source is discharged, the solenoid valve 802 is opened. At this time, the channel of the discharge port 801 is not blocked, and the mixed solvent is discharged through the discharge port 801. When passing through the transmission blade 806, the shape of the transmission blade 806 can drive the transmission blade 806 to rotate, and then the rotation of the transmission blade 806 drives the second connecting rod 805, the sleeve 803 and the scraper plate 804 to rotate, so that the scraper plate 804 can scrape the bottom of the shell 1 when it rotates, thereby preventing the solvent from sinking to the bottom when it is discharged, causing a waste of resources.
