[0016] A method for preparing a device for preparing a water-soluble fertilizer containing amino acids, the preparation method is as follows:

[0017] S1. First, install the two groups of support rods on the outside of the connecting shaft respectively, clamp the connecting head inside the connecting groove, and pull the positioning pin at the same time to make the positioning pin disengage from the inside of the connecting groove and compress the support spring until the positioning pin completely enters the inside of the movable groove. Then clamp the connecting head at the bottom of the connecting groove, align the positioning groove with the end of the positioning pin, release the positioning pin, and under the elastic potential energy of the support spring, make the positioning pin clamp inside the positioning groove. Similarly, install and fix the other group of support rods. At this time, the scraper and the cleaning brush are both in contact with the inner wall of the device body.

[0018] S2. Secondly, the corresponding water-soluble fertilizer is introduced into the interior of the device body through the connecting pipe at the upper end of the tank cover, and then the amino acid is introduced into the interior of the collecting box through the hopper, and is carried by the weighing plate. At this time, the detection end of the weight sensor detects the weight of the amino acid. When the required amount of addition is reached, a buzzer on the outside of the control panel is used to remind, and then the output end of the feeding motor drives the movable shaft to rotate, so that the auxiliary plate and the weighing plate are reversed, and the amino acid fertilizer is introduced into the interior of the connecting pipe, and finally falls into the interior of the device body;

[0019] S3. Then, the output end of the driving motor drives the gear to mesh and reverse along the outer side of the tooth groove, so that the baffle enters the interior of the collection box along the moving hole, and at the same time drives the auxiliary block to move along the interior of the auxiliary groove until the end of the baffle enters the interior of the top groove, so that the connecting pipe is closed, thereby isolating the collection box to prevent water from entering the inner wall of the collection box, causing the subsequent amino acid feeding to be unsmooth;

[0020] S4. Finally, by starting the stirring motor, the output end of the stirring motor drives the connecting shaft and the stirring blades to rotate, the water-soluble fertilizer and the amino acid are fully stirred, and the material is discharged through the discharge port. After the discharge is completed, the scraper and the cleaning brush are driven by the connecting shaft to clean the inner wall of the device body. At the same time, the water inlet interface is connected to the external water pipe, and the clean water is introduced into the interior of the water pipe. It is sprayed along the inner wall of the device body through the nozzle, and the residues after cleaning by the scraper and the cleaning brush can be cleaned.

[0021] The working principle and beneficial effects of the present invention are:

[0022] 1. The function of the automatic unloading assembly of the present invention is to introduce the corresponding water-soluble fertilizer into the interior of the device body through the connecting pipe at the upper end of the tank cover, and then introduce the amino acid into the interior of the collecting box through the hopper, and carry it through the weighing plate. At this time, the detection end of the weight sensor detects the weight of the amino acid. When the required amount of addition is reached, a buzzer on the outside of the control panel is used to remind, and then the output end of the unloading motor drives the movable shaft to rotate, so that the auxiliary plate and the weighing plate are reversed, and the amino acid fertilizer is introduced into the interior of the connecting pipe, and finally falls into the interior of the device body, and automatic unloading can be performed;

[0023] At the same time, the aggregate box can be partitioned to prevent water from entering the inner wall of the aggregate box, which would cause subsequent unsmooth amino acid feeding.

[0024] 2. The present invention uses the function of the cleaning component to start the stirring motor so that the output end of the stirring motor drives the connecting shaft and the stirring blade to rotate, fully stirs the water-soluble fertilizer and the amino acid, and discharges the material through the discharge port. After the discharge is completed, the scraper and the cleaning brush are driven by the connecting shaft to scrape and clean the inner wall of the device body to avoid scaling of the inner wall of the device body, thereby ensuring that the subsequent aqueous solution can be prepared normally without pollution.

[0025] 3. The present invention can use the water inlet interface, water pipe and nozzle to rinse the cleaning component with clean water during the cleaning process, thereby speeding up the cleaning of the cleaning component. BRIEF DESCRIPTION OF THE DRAWINGS

10. A method for preparing a water-soluble fertilizer containing amino acids, according to any one of claims 1 to 9, characterized in that: The preparation method is as follows: S1. First, two groups of support rods (81) are respectively installed on the outside of the connecting shaft (6), and the connecting head (84) is clamped inside the connecting groove (85). At the same time, the positioning pin (88) is pulled so that the positioning pin (88) is separated from the inside of the connecting groove (85) and the supporting spring (89) is compressed until the positioning pin (88) completely enters the inside of the moving groove (86). Then, the connecting head (84) is clamped at the bottom of the connecting groove (85), and the positioning groove (87) is aligned with the end of the positioning pin (88). The positioning pin (88) is loosened, and the positioning pin (88) is clamped inside the positioning groove (87) under the elastic potential energy of the supporting spring (89). Similarly, the other group of support rods (81) is also installed and fixed. At this time, the scraper (82) and the cleaning brush (83) are both in contact with the inner wall of the device body (1); S2. Next, the corresponding water-soluble fertilizer is introduced into the interior of the device body (1) through the connecting pipe at the upper end of the tank cover (2), and then the amino acid is introduced into the interior of the collecting box (91) through the hopper (93), and is carried by the weighing plate (97). At this time, the detection end of the weight sensor (98) detects the weight of the amino acid. When the required amount of addition is reached, a buzzer on the outside of the control panel is used to remind, and then the output end of the feeding motor (94) drives the movable shaft (95) to rotate, so that the auxiliary plate (96) and the weighing plate (97) are reversed, and the amino acid fertilizer is introduced into the interior of the connecting pipe (92), and finally falls into the interior of the device body (1); S3. Then, the output end of the driving motor (914) drives the gear (915) to mesh and reverse along the outer side of the tooth groove (916), so that the baffle (99) enters the interior of the material collection box (91) along the moving hole, and at the same time drives the auxiliary block (910) to move along the interior of the auxiliary groove (911) until the end of the baffle (99) enters the interior of the top groove (912), so that the connecting pipe (92) is closed, thereby isolating the material collection box (91) to prevent water from entering the inner wall of the material collection box (91), which would cause the subsequent amino acid feeding to be unsmooth; S4. Finally, by starting the stirring motor (5), the output end of the stirring motor (5) drives the connecting shaft (6) and the stirring blade (7) to rotate, the water-soluble fertilizer and the amino acid are fully stirred, and the material is discharged through the discharge port (3). After the discharge is completed, the scraper (82) and the cleaning brush (83) are driven by the connecting shaft (6) to clean the inner wall of the device body (1). At the same time, the water inlet interface (10) is connected to the external water pipe, and clean water is introduced into the inside of the water pipe (11). The water is sprayed along the inner wall of the device body (1) through the nozzle (12), and the residues after cleaning by the scraper (82) and the cleaning brush (83) can be cleaned.
