[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Example 1

[0027] like Figure 1 and Figure 2 As shown, this embodiment provides a mixing device, including a base 1, a lifting assembly 2 is provided in the inner cavity of the base 1, upright plates 3 are symmetrically fixedly connected to the left and right sides of the upper end of the base 1, a limiting assembly 4 is provided in the middle of the upper end of the base 1, a mixing tank 5 is movably installed on the inner surface of the limiting assembly 4, a fixing assembly 6 is symmetrically provided in the middle of the lower side of the two upright plates 3 opposite to each other, a cover plate 7 is threadedly connected to the outer surface of the lifting assembly 2, and a mixing assembly 8 is provided in the middle of the lower end of the cover plate 7.

[0028] The aforementioned cover plate 7 consists of a cover plate body and several feed pipes that are fixedly connected to and pass through the cover plate body. The arrangement of several feed pipes allows multiple fertilizer raw materials to be simultaneously transported into the mixing tank 5 for fertilizer raw material mixing. For example, in this embodiment, the fertilizer raw materials include multiple components such as polyglutamic acid, γ-aminobutyric acid, binder, dispersant, and probiotic strains, which can be determined according to the fertilizer formula.

[0029] When in use, turn on the lifting component 2 to raise the position of the cover plate 7 and the stirring component 8, put the stirring tank 5 into the limiting component 4, turn on the lifting component 2 to lower the position of the cover plate 7 and the stirring component 8, so that the lower end of the cover plate 7 abuts against the upper end of the stirring tank 5.

[0030] During the descent of the cover plate 7, both fixing components 6 will operate, thereby completing the clamping and fixing of the mixing tank 5.

[0031] Different fertilizer raw materials are fed into the mixing tank 5 through several feed pipes, and the mixing component 8 is turned on to mix the different fertilizer raw materials in the mixing tank 5.

[0032] After the mixing operation is completed, the base 1 is opened to raise the position of the cover plate 7 and the mixing component 8. During the rise of the cover plate 7, the two fixing components 6 are driven to operate, so that the two fixing components 6 no longer clamp and fix the mixing tank 5. Then the mixing tank 5 is taken out from the limiting component 4, and all the mixed fertilizer raw materials in the mixing tank 5 are taken out for later use. Then the remaining fertilizer raw materials in the mixing tank 5 are cleaned and removed.

[0033] Example 2

[0034] The only difference between this embodiment and Embodiment 1 is that, see reference... Figure 3The lifting assembly 2 includes a motor 21, which is fixedly connected to the lower left side of the inner surface of the base 1. The output end of the motor 21 is fixedly connected to a threaded rod 23 via a coupling. A threaded rod 24 is rotatably connected to the lower right side of the inner surface of the base 1. A pulley group 22 is fixedly connected to the lower outer surface of the threaded rod 23 and the threaded rod 24. The upper ends of the threaded rod 23 and the threaded rod 24 pass through the upper left and right sides of the inner surface of the base 1 and the lower middle of the two vertical plates 3, respectively, and extend into the two vertical plates 3. The cover plate 7 is threadedly connected to the outer surfaces of the threaded rod 23 and the threaded rod 24.

[0035] Further reading Figure 4 The limiting component 4 includes a circular base 41, which is fixedly connected to the middle of the upper end of the base 1. A circular groove 42 is provided in the middle of the upper end of the circular base 41. The mixing tank 5 is movably installed on the inner surface of the circular groove 42. The mixing component 8 includes a second motor 81, which is fixedly connected to the middle of the upper end of the cover plate 7. A rotating rod 82 is fixedly connected to the output end of the second motor 81 through a coupling. The lower end of the rotating rod 82 passes through the upper end of the cover plate 7 and extends to the lower side of the cover plate 7. Several mixing plates 83 are fixedly connected to the outer surface of the rotating rod 82.

[0036] Further reading Figure 5 The fixing component 6 includes a pressing component 62, which is located on the lower right side of the cover plate 7. A clamping component is located on the lower middle side of the left side of the right upright plate 3. The clamping component includes a housing 611, which is fixedly connected to the lower middle side of the left side of the right upright plate 3. A sliding rod 614 is slidably connected through the middle side of the left side of the housing 611 and extends into the housing 611. An inclined block 612 is fixedly connected to the right end of the sliding rod 614. A spring 613 is sleeved on the outer surface of the sliding rod 614. The left and right ends of the spring 613 are fixedly connected to the left side of the inner surface of the housing 611 and the left end of the inclined block 612, respectively. An arc-shaped clamping plate 615 is fixedly connected to the left end of the sliding rod 614. Several rubber strips 616 are fixedly connected to the inner surface of the arc-shaped clamping plate 615, and the several rubber strips 616 are distributed in an arc-shaped array. The pressing component 62 includes a connecting rod 621, which is fixedly connected to the lower right side of the cover plate 7. A pressing block 622 is fixedly connected to the lower end of the connecting rod 621.

[0037] When in use, turn on motor 21 to drive threaded rod 23 to rotate forward. Under the action of pulley group 22, threaded rod 24 will rotate simultaneously, thereby driving cover plate 7 and stirring assembly 8 to rise to a position that will not affect the placement of stirring tank 5 into round groove 42.

[0038] Then, the mixing tank 5 is placed into the circular groove 42. The limiting component 4 limits the position of the mixing tank 5. The mixing tank 5 placed in the circular groove 42 can ensure that the mixing component 8 can enter the mixing tank 5 after it descends. At the same time, it allows the two extrusion blocks 622 to be inserted into the two shells 611 respectively to extrude the two inclined blocks 612, thereby ensuring the normal operation of the two fixing components 6 and ensuring the stability of the process of mixing fertilizer raw materials of different components using this device.

[0039] When the motor 21 is turned on, the threaded rod 23 reverses. Under the same working principle, the lifting component 2 moves and drives the cover plate 7, the stirring component 8 and the two extrusion components 62 to continuously descend until the lower end of the cover plate 7 abuts against the upper end of the stirring tank 5.

[0040] During this process, the two extrusion blocks 622 will enter the two housings 611 respectively, and extrude the two inclined blocks 612 respectively, thereby driving the two slide rods 614 to move closer to each other at the same time, thereby driving the two arc-shaped clamps 615 to move closer to each other at the same time.

[0041] When the lower end of the cover plate 7 abuts against the upper end of the mixing tank 5, the two pressing blocks 622 press against the two inclined blocks 612 respectively, so that the two arc-shaped clamping plates 615 can clamp and fix the mixing tank 5, thereby preventing the mixing tank 5 from shaking around and affecting the normal mixing process when the mixing assembly 8 is turned on to mix different components of fertilizer raw materials in the mixing tank 5.

[0042] Several rubber strips 616 serve to increase friction, making the clamping and fixing of the two arc-shaped clamps 615 on the mixing tank 5 more stable.

[0043] At this time, both springs 613 are in a compressed state. When both extrusion blocks 622 rise and no longer extrude on the two inclined blocks 612, the reaction force of the two springs 613 causes the two sliding rods 614 to move away from each other at the same time, thereby driving the two arc-shaped clamps 615 to move away from each other and no longer clamping and fixing the mixing barrel 5, so that the mixing barrel 5 can be taken out from the circular groove 42.

[0044] After completing the above operations, fertilizer raw materials of different components are put into the mixing tank 5 through several feed pipes. In this way, fertilizer raw materials of different components can be put into the mixing tank 5 at the same time, thereby saving the mixing time of fertilizer raw materials of different components and improving the mixing efficiency of fertilizer raw materials of different components.

[0045] After the delivery of fertilizer raw materials of different components is completed, the motor 81 is turned on to drive the rotating rod 82 to rotate, thereby driving several mixing plates 83 to rotate, and mixing the fertilizer raw materials of different components in the mixing tank 5. By mixing different types of fertilizers, different types of fertilizers can form a complementary effect, allowing crops to absorb and utilize nutrients more effectively.

[0046] After the mixing of different fertilizer raw materials is completed, motor 21 is turned on, which causes the lifting component 2 to run and drive the cover plate 7 and the mixing component 8 to rise to a position that will not affect the removal of the mixing tank 5 from the circular groove 42. Then the mixing tank 5 is removed from the circular groove 42, and the mixed fertilizer raw materials in the mixing tank 5 can be obtained completely and quickly.

[0047] After all the mixed fertilizer raw materials are removed from the mixing tank 5, the remaining mixed fertilizer raw materials in the mixing tank 5 are cleaned and removed to prevent the mixed fertilizer raw materials from remaining in the mixing tank 5 and causing contamination to the fertilizer raw materials produced later.

[0048] It should be noted that the specific installation method, circuit connection method and control method of motor 21 and motor 81 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0049] The working principle of this utility model is as follows:

[0050] When the motor 21 is turned on, it drives the threaded rod 23 to rotate forward. Under the action of the pulley group 22, it drives the threaded rod 24 to rotate simultaneously, thereby causing the cover plate 7 and the stirring assembly 8 to rise.

[0051] Place the mixing tank 5 into the circular groove 42, turn on the motor 21 to drive the threaded rod 23 to reverse, so that the lifting component 2 moves and drives the cover plate 7, the mixing component 8 and the two extrusion components 62 to continuously descend until the lower end of the cover plate 7 abuts against the upper end of the mixing tank 5.

[0052] The two extrusion blocks 622 will enter the two shells 611 respectively, and extrude the two inclined blocks 612 respectively, thereby driving the two arc-shaped clamping plates 615 to move closer to each other at the same time, thus completing the clamping and fixing of the mixing tank 5.

[0053] Different fertilizer raw materials are fed into the mixing tank 5 through several feed pipes. The motor 81 is turned on to drive the rotating rod 82 to rotate, which in turn drives several mixing plates 83 to rotate, thus mixing the different fertilizer raw materials in the mixing tank 5.

[0054] After the mixing is completed, the lifting component 2 is activated, which drives the cover plate 7 and the mixing component 8 to rise, remove the mixing tank 5 from the circular groove 42, remove all the mixed fertilizer raw materials in the mixing tank 5, and clean and remove the remaining mixed fertilizer raw materials in the mixing tank 5.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
