[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] like Figure 1-3As shown, this utility model discloses an automatic agricultural nutrient solution mixing device, including a base 1. A movable storage tank 8 is provided at the top of the base 1. A stirring assembly is provided inside the storage tank 8. Multiple inlet pipes 9 are fixedly installed at equal intervals at the top of the storage tank 8. Solenoid valves A are fixedly installed inside the multiple inlet pipes 9. An inlet hopper 10 is fixedly installed at the top of the multiple inlet pipes 9. The inside of the inlet hopper 10 is divided into multiple inlet slots by a partition 13. Scale lines 12 are engraved on the side walls of the multiple inlet slots. Nutrient solution pipes 11 are arranged at the top of the multiple inlet slots. The nutrient solution pipes 11 are connected to the nutrient solution raw material storage tank through a feed pump.

[0018] Specifically, the mixing equipment can stir the nutrient solution inside the storage tank 8 through the stirring component installed inside the storage tank 8. At the same time, the storage tank 8 and the base 1 are movable. The second drive motor 17 drives the cam 18 to rotate. The cam 18 squeezes the moving fixed bar 4 to realize the reciprocating movement of the storage tank 8, which further improves the mixing efficiency of the nutrient solution.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses an automatic agricultural nutrient solution mixing device. The stirring assembly includes multiple stirring shafts 15, which are rotatably connected to both sides of the inner wall of the storage tank 8. A gear 16 is fixedly installed at one end of each stirring shaft 15, and two adjacent gears 16 are meshed together. A first drive motor 7 is fixedly installed on one side wall of the storage tank 8, and the output shaft of the first drive motor 7 is fixedly connected to one end of the corresponding stirring shaft 15.

[0020] A transparent observation window 6 is fixedly installed on one side of the liquid storage tank 8, and an outlet pipe 14 is fixedly installed at the bottom corner of one side of the liquid storage tank 8. A solenoid valve B is fixedly installed inside the outlet pipe 14.

[0021] Specifically, the first drive motor 7 drives the stirring shaft 15 to rotate, and the multiple stirring shafts 15 are meshed with gears 16 to achieve synchronous rotation of the multiple stirring shafts 15.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses an automatic agricultural nutrient solution mixing device. An installation groove 2 is provided at the center of the top of the base 1. Fixing strips 4 are fixed on both sides of the bottom of the storage tank 8. Connecting rods 3 are fixedly installed on both sides of the inner wall of the installation groove 2. The two connecting rods 3 are interlocked with the fixing strips 4.

[0023] Both ends of the connecting rod 3 are fitted with return springs 5. One end of the return spring 5 is fixedly connected to the groove wall of the mounting groove 2, and the other side of the return spring 5 is fixedly connected to the side of the fixing strip 4.

[0024] The bottom of the mounting slot 2 is fixedly mounted with a second drive motor 17, and the output shaft of the second drive motor 17 is fixedly mounted with a cam 18. The cam 18 is in contact with the other side of the fixing strip 4.

[0025] Specifically, the cam 18 presses the fixing bar 4 to move to one side. At this time, the return spring 5 is in a compressed state. When the protruding end of the cam 18 separates from the fixing bar 4, the fixing bar 4 is pushed back by the return spring 5, thereby realizing the reciprocating swing of the liquid storage tank 8.

[0026] In specific implementation, when using the automatic nutrient solution mixing equipment, the raw materials of the nutrient solution are first fed into the inlet tank through the nutrient solution conduit 11 according to the mixing ratio. The amount of nutrient solution is observed through the scale line 12 to ensure that the nutrient solution is mixed according to the ratio. Then, the solenoid valve A is opened, and the nutrient solution flows into the storage tank 8 through the inlet conduit 9. Next, the first drive motor 7 and the second drive motor 17 are turned on. The first drive motor 7 drives the connected stirring shaft 15 to rotate. Multiple stirring shafts 15 rotate synchronously through the meshing of gears 16. At the same time, the second drive motor 17 drives the cam 18 to rotate. The rotation of the cam 18 compresses the movement of the fixing bar 4, and the fixing bar 4 is reset by the return spring 5, causing the storage tank 8 to swing back and forth. This causes the nutrient solution inside the storage tank 8 to swing back and forth, effectively improving the nutrient solution mixing efficiency. Then, the solenoid valve B is opened, and the mixed nutrient solution flows out through the outlet pipe 14.
