[0043] Specifically, when the particles in the cylinder 3 need to be discharged, one side of the preparation box 2 is lifted upward by the lifting device 32, and the preparation box 2 drives the rotating shaft 31 to rotate and tilt on the support 30, and the particles in the cylinder 3 can be easily discharged.

[0044] Embodiment three:

[0045] Reference Figure 3 and Figure 5 , which is basically the same as Example 2, and further discloses a specific implementation scheme of the circulation unit.

[0046] The above-mentioned circulation part includes a water pump 18 fixedly installed on the outer wall of the preparation box 2, and the input end of the water pump 18 is fixedly connected to a liquid inlet pipe 20 extending to the bottom of the preparation box 2, wherein the output end of the water pump 18 is fixedly connected to a discharge pipe 19, and the upper horizontal pipe 8 and the lower horizontal pipe 7 are fixedly connected by a vertical pipe 9, and the discharge pipe 19 is fixedly connected and communicated with the vertical pipe 9.

[0050] The lower ends of the upper transverse tube 8 and the lower transverse tube 7 are fixedly connected with a fixed tube 24, and the fixed tube 24 is communicated with the upper transverse tube 8 and the lower transverse tube 7. An inner tube 25 is sleeved in the fixed tube 24, and the inner tube 25 is communicated with the fixed tube 24 and the nozzle 10. The nozzle 10 is fixedly connected to the lower end of the inner tube 25. A spring 26 is installed between the two nozzles 10 and the upper transverse tube 8 and the lower transverse tube 7. The preparation box 2 is provided with a boosting part for indirectly boosting the pressure of the discharge pipe 19.

[0054] The outer wall of the preparation box 2 is plugged with a cross bar 21 extending to its inner bottom, a stirring paddle 22 is fixedly mounted on the outer wall of the cross bar 21, a third gear 23 meshing with the driving gear 13 is fixedly mounted on the cross bar 21, and one end of the cross bar 21 is rotatably connected to the reciprocating plate 17.

[0056] In practice, the specific preparation steps are as follows:

[0057] Step 1: Place the granular raw materials for preparing liquid fertilizer in the cylinder 3, and pour water into the inner bottom of the preparation box 2;

[0058] Step 2: The cylinder 3 is rotated continuously, and the nozzle 11 sprays the liquid at the bottom of the preparation box 2;

[0059] Step 3: Make the rotating cylinder 3 swing back and forth along its axis;

[0060] Step 4: The nozzle 11 indirectly approaches and moves away from the inner wall and the outer wall of the cylinder 3;

[0061] Step 5: Stir the liquid at the bottom of the preparation box 2 by using the stirring paddle 22 .

[0062] When the liquid fertilizer preparation device is used, the granular raw material is placed in the cylinder 3, and water is poured into the inner bottom of the preparation box 2, and then the whole device is started, so that the water pump 18 will extract the water at the bottom of the preparation box 2 through the liquid inlet pipe 20, and deliver it to the vertical pipe 9 through the liquid discharge pipe 19, and the vertical pipe 9 will deliver the water to the upper horizontal pipe 8 and the lower horizontal pipe 7, and the upper horizontal pipe 8 and the lower horizontal pipe 7 will deliver the water to the two nozzles 10, and the two nozzles 10 will spray water through the nozzle 11, and the nozzle 10 located in the preparation box 2 will spray water into the cylinder 3 to flush and dissolve the granular raw material in the cylinder 3, and the dissolved fertilizer will flow back to the inner bottom of the preparation box 2 through the water hole 4, and the granular raw material can complete the dissolution work more efficiently under the flushing action of water, and the granular raw material that cannot be dissolved will not enter the liquid fertilizer, so there is no need to filter out granular impurities from the liquid fertilizer, which indirectly improves the preparation efficiency of the liquid fertilizer;

[0063] During the preparation period, the motor 12 will drive the driving gear 13 to rotate, the driving gear 13 will drive the first gear 14 meshing therewith to rotate, the first gear 14 will drive the short tube 5 to rotate, the short tube 5 will drive the cylinder 3 to rotate, and the granular raw materials in the cylinder 3 will roll differently inside it, so the granular raw materials will rub against each other, and cooperate with the liquid sprayed by the nozzle 11, so as to significantly improve the dissolution speed of the granular raw materials, and the nozzle 10 located at the top of the preparation box 2 will spray water to the top of the cylinder 3, so as to flush the granular raw materials blocked in the water hole 4 back into the cylinder 3, thereby ensuring the efficiency of the cylinder 3 in dissolving the granular raw materials and indirectly improving the preparation efficiency of the liquid fertilizer.

[0064] When the driving gear 13 rotates, the driving gear 13 will also drive the second gear 16 to rotate, and the second gear 16 will drive the reciprocating screw 15 to rotate, and the reciprocating screw 15 will drive the reciprocating plate 17 to slide back and forth, and the reciprocating plate 17 will drive the cylinder 3 to swing back and forth in the preparation box 2 through the short tube 5. The swinging cylinder 3 will make the granular raw materials inside swing back and forth, and the granular raw materials can be better dissolved, further improving the preparation efficiency of the liquid fertilizer, and the swinging cylinder 3 will make the nozzle 11 more comprehensively rinse the granular raw materials and the cylinder 3, further improving the preparation efficiency of the liquid fertilizer, and the water hole 4 on the cylinder 3 is less likely to be blocked.

[0065] When the reciprocating plate 17 slides back and forth, the reciprocating plate 17 will indirectly stretch and compress the telescopic airbag 27. When the telescopic airbag 27 is stretched, negative pressure will be generated inside it, and the liquid at the bottom of the preparation box 2 will be sucked through the suction tube 28. When the telescopic airbag 27 is compressed, the liquid inside it will be transported to the discharge pipe 19 through the infusion tube 29, and the flow rate and pressure in the discharge pipe 19 will increase. Therefore, the indirectly compressed telescopic airbag 27 will cause the flow rate and pressure in the discharge pipe 19 to fluctuate. When the flow rate and pressure increase, the nozzle 11 will not be able to discharge the liquid in the nozzle 10 in time. The liquid will push the inner tube 25 to slide toward the nozzle 10 and drive the nozzle 10 to move downward. When the flow rate and pressure decrease, the spring 26 will drive the inner tube 25 and the nozzle 10 to move in the opposite direction and reset. Therefore, the nozzle 10 will drive the nozzle 11 to indirectly approach and move away from the inner wall and outer wall of the cylinder 3. This fluctuating liquid will make the granular raw material more efficiently dissolved and the water hole 4 can be efficiently unblocked. In the cylinder 3, the nozzle 10 swinging up and down can also stir and break up the granular raw material in the cylinder 3, so as to further improve the dissolution efficiency of the granular raw material.
