[0029] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0030] like Figure 1-Figure 5 As shown:

[0031] The stirring device for liquid fertilizer production provided in one embodiment of the present application comprises a tank body 1, a stirring structure 12 is provided inside the tank body 1, a feeding port 2 is provided at the upper end of the tank body 1 for adding powdered raw materials, and a water inlet pipe 3 and a liquid discharge pipe 4 with a valve are connected to the tank body 1. Specifically, the liquid discharge pipe 4 is connected to the bottom of the tank body 1, and the water inlet pipe 3 is connected to the upper side end of the tank body 1.

[0032] The upper end of the water inlet pipe 3 is connected with a liquid adding pipe 5 for adding liquid raw materials, and the liquid adding pipe 5 is distributed vertically.

[0033] The stirring structure 12 is connected to the motor 7 via a universal shaft 9 , and the motor 7 is fixed to the upper end of the tank body 1 .

[0034] In this embodiment, a mounting frame 8 is fixed to the upper end of the tank body 1, and the motor 7 is fixed on the mounting frame 8. A through hole 6 is opened at the upper end of the tank body 1. The universal shaft 9 passes through the through hole 6 and has an annular gap between the through hole 6. One end of the universal shaft 9 is fixedly connected to the output shaft of the motor 7, and the other end of the universal shaft 9 is fixedly connected to the stirring structure 12.

[0035] The stirring structure 12 is connected to a driving mechanism 15 which can drive the stirring structure 12 to swing back and forth when the stirring structure 12 rotates.

[0036] In the embodiment, a bracket 10 is fixed to the bottom of the tank body 1 for supporting the tank body 1 .

[0037] When in use, water required for stirring liquid fertilizer is injected into the tank body 1 through the water inlet pipe 3, and liquid raw materials are added from the liquid adding pipe 5, so that the liquid raw materials first enter the water inlet pipe 3 and are premixed with water, and then flow into the tank body 1 together with the water, and powdered raw materials are added from the feeding port 2. While adding materials, the motor 7 and the driving mechanism 15 are started, and the motor 7 drives the stirring structure 12 to rotate through the universal shaft 9. While the stirring structure 12 rotates, the driving mechanism 15 drives the stirring structure 12 to swing back and forth. The stirring structure 12 stirs and mixes the materials in the tank body 1 while rotating and swinging back and forth. After the stirring is completed to form liquid fertilizer, the valve on the discharge pipe 4 is opened to discharge the liquid fertilizer from the discharge pipe 4.

[0038] The stirring device for liquid fertilizer production provided in this embodiment is connected with a universal shaft 9 between the stirring structure 12 and the motor 7, and the stirring structure 12 is connected with a driving mechanism 15 that can drive the stirring structure 12 to swing back and forth when the stirring structure 12 rotates, so that the stirring structure 12 can swing back and forth while rotating, and then the stirring position and stirring direction of the stirring structure 12 can be continuously changed. Therefore, under the condition of ensuring that the raw materials are fully mixed, compared with the existing method of stirring at a fixed position, the time used for the entire stirring process can be shortened, and the stirring efficiency can be improved.

[0039] In some embodiments of the present application, the driving mechanism 15 includes a sleeve 16 and a rectangular ring 17. The sleeve 16 is sleeved on the stirring structure 12 and is rotatably connected to the stirring structure 12 through a bearing 18. Specifically, the outer ring of the bearing 18 is fixedly connected to the inner wall of the sleeve 16, and the inner ring of the bearing 18 is fixedly connected to the stirring structure 12.

[0040] The rectangular ring 17 is sleeved on the sleeve 16 , and an annular gap is provided between the rectangular ring 17 and the sleeve 16 .

[0041] The rectangular ring 17 is connected to a reciprocating linear motion mechanism 19 which can drive the rectangular ring 17 to perform reciprocating linear motion in the horizontal direction.

[0042] Furthermore, a reciprocating linear motion mechanism 19 is installed on the tank body 1 .

[0043] In this embodiment, the reciprocating linear motion mechanism 19 drives the rectangular ring 17 to slowly reciprocate left and right.

[0044] When in use, after the reciprocating linear motion mechanism 19 drives the rectangular ring 17 to move to the left, the right end of the rectangular ring 17 first contacts the sleeve 16, and then because the stirring structure 12 is connected to the motor 7 through the universal shaft 9, and the sleeve 16 is rotationally connected to the stirring structure 12, after the rectangular ring 17 continues to move to the left, the rectangular ring 17 will push the sleeve 16 to rotate left around the rotation center of the universal shaft 9, and the sleeve 16 drives the rotating stirring structure 12 to rotate left synchronously with it. After the stirring structure 12 rotates to the left by a certain angle, the reciprocating linear motion mechanism 19 drives the rectangular ring 17 to start moving to the right. After the rectangular ring 17 moves to the right, due to the sleeve 16 and the stirring structure 12 Due to its own gravity and the gap between the left end of the rectangular ring 17 and the sleeve 16, the sleeve 16 first presses against the right end of the rectangular ring 17 and moves to the right with the rectangular ring 17. When the sleeve 16 and the stirring structure 12 rotate to a vertical state and the rectangular ring 17 continues to move to the right, the left end of the rectangular ring 17 will contact the sleeve 16 and push the sleeve 16 to rotate to the right. The sleeve 16 drives the self-rotating stirring structure 12 to rotate to the right synchronously. After the stirring structure 12 rotates to the right by a certain angle, the rectangular ring 17 starts to move to the left, and the stirring structure 12 rotates to the left. Therefore, after the rectangular ring 17 moves back and forth, the stirring structure 12 can swing back and forth while rotating.

[0045] In some embodiments of the present application, the reciprocating linear motion mechanism 19 adopts an electric push rod 20 capable of reciprocating telescopic movement. The electric push rod 20 is fixed on the tank body 1, and the free end of the electric push rod 20 is fixedly connected to the rectangular ring 17 through a connecting frame 22.

[0046] In this embodiment, the electric push rod 20 is fixed on the outer wall of the right end of the tank body 1, and the push rod of the electric push rod 20 penetrates the tank wall of the tank body 1 and is slidably connected to the tank wall. The reciprocating telescopic method of the electric push rod 20 is a prior art and will not be described in detail.

[0047] When in use, the electric push rod 20 extends, the rectangular ring 17 moves to the left, the electric push rod 20 shortens, the rectangular ring 17 moves to the right, and after the electric push rod 20 reciprocates and retracts, the rectangular ring 17 reciprocates and moves linearly left and right.

[0048] In some embodiments of the present application, two push wheels 21 are provided on the rectangular ring 17 and are symmetrically distributed along the swing direction of the stirring structure 12, and the push wheels 21 are rotatably connected to the rectangular ring 17, so that the push wheels 21 can smoothly push the sleeve 16 to rotate around the rotation center of the universal shaft 9.

[0049] In order to improve the stability of the connection between the sleeve 16 and the stirring structure 12 and to allow the stirring structure 12 to rotate smoothly, in some embodiments of the present application, the number of the bearings 18 is two.

[0050] In some embodiments of the present application, a material distribution trough 11 located below the feeding port 2 is fixedly mounted on the sleeve 16, and the bottom of the material distribution trough 11 is a mesh structure.

[0051] When in use, the powdered raw material first falls into the distribution trough 11 from the feeding port 2, and water and liquid raw materials are added to the tank body 1 at the same time. Since the distribution trough 11 is fixed on the sleeve 16, after the sleeve 16 swings back and forth, the sleeve 16 drives the distribution trough 11 to swing back and forth synchronously with it. After the distribution trough 11 swings back and forth, the powdered raw material will flow back and forth in the distribution trough 11 along the swinging direction of the distribution trough 11, and will pass through the mesh holes of the mesh plate structure and fall evenly onto the liquid surface of the liquid. At the same time, the stirring structure 12 is rotating, so the powdered raw material can be evenly and quickly mixed in the liquid, which not only improves the stirring efficiency, but also avoids the problem that the powdered raw material contacts the liquid and is easy to agglomerate after being directly poured into the tank body 1 from the feeding port 2.

[0052] In some embodiments of the present application, the stirring structure 12 includes a rotating shaft 13, on which a plurality of stirring blades 14 are fixed;

[0053] The rotating shaft 13 is connected to the other end of the universal shaft 9 , and the sleeve 16 is sleeved on the rotating shaft 13 and is rotatably connected to the rotating shaft 13 through a bearing 18 .

[0054] Specifically, the inner ring of the bearing 18 is fixedly connected to the outer wall of the rotating shaft 13 .

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
