Description

Technical Field

[0001] This invention relates to the field of mixing tanks for suspension concentrates, and particularly to a mixing tank for suspension concentrates containing pyrimethanil, fludioxonil, and terpineol. Background Technology

[0002] Azoxystrobin, fludioxonil, and terpineol are three agricultural fungicides with different fungicidal mechanisms. Furthermore, there is no cross-resistance among them. However, the individual application of these three fungicides results in poor efficacy against grape gray mold, with a short duration of action. In practice, increasing the dosage of each individual fungicide is often used to improve the fungicidal effect against grape gray mold, but this method causes serious environmental pollution and is costly. To address this issue, a synergistic fungicide can be prepared by combining azoxystrobin, fludioxonil, and terpineol. Compared to single components, the fungicidal effect is significantly improved. At low doses, it not only exhibits significant fungicidal activity but also demonstrates good safety, as compared to the technical solution disclosed in Reference 1 (Chinese Invention Patent No. CN114946864B, entitled "Synergistic Fungicide Containing Azoxystrobin, Fludioxonil, and Terpineol and Its Application").

[0003] However, after on-site investigation and trial use of various compound preparation devices, it was found that in the mixing stage of the mixing tank, the mixing effect is often mediocre due to the simple structure of the mixing tank's stirring blades and the single stirring function / method. This is similar to the technical solutions disclosed in comparative literature 2 (Chinese utility model patent with announcement number CN211886498U, entitled "A mixing tank for producing suspensions containing pyraclostrobin and fludioxonil") and comparative literature 3 (Chinese utility model patent with announcement number CN209219019U, entitled "A uniformly mixed pesticide aqueous suspension production equipment").

[0004] Therefore, it is necessary to invent a multifunctional combined suspension mixing vessel that can effectively improve the mixing effect. Summary of the Invention

[0005] To address the above problems, this invention proposes a mixing tank for a suspension containing pyraclostrobin, fludioxonil, and terpineol. The technical solution adopted is as follows:

[0006] A mixing vessel for a suspension containing pyraclostrobin, fludioxonil and terpineol includes a support and a shell disposed on the support, a mixing mechanism sealed on the shell, and a discharge mechanism installed at the bottom of the shell.

[0007] The mixing mechanism includes a drive assembly sealed on the housing with the drive shaft extending into the housing, a mixing assembly one and a mixing assembly two that are radially distributed and staggeredly fixed on the drive shaft, and a lifting assembly for driving the mixing assembly one and the mixing assembly two to perform a mixing mode.

[0008] The mixing assembly includes a mixing rod 1 fixedly mounted on a drive shaft, a mixing rod 2 rotatably mounted on the inner end of the mixing rod 1, a mixing rod 3 rotatably mounted on the inner end of the mixing rod 2, a control rod with one end rotatably connected to the mixing rod 3 and the other end rotatably and slidably connected to the mixing rod 2, and a top rod 1 with one end rotatably and slidably connected to the mixing rod 3 and the other end fixedly connected to the lifting assembly.

[0009] The mixing assembly 2 includes a stirring rod 4 fixedly mounted on the drive shaft, several stirring teeth rotatably mounted on the stirring rod 4 and synchronously rotated through a connecting rod assembly, and a top rod 2 whose one end is fixedly connected to the lifting assembly and whose other end drives the connecting rod assembly to move.

[0010] Furthermore, the mixing assembly also includes several auxiliary rods rotatably mounted on the mixing rod and rotating synchronously through the connecting rod, a lever rotatably mounted on the mixing rod and connected to the connecting rod at one end, and a return spring installed between the mixing rod and the other end of the lever; the top rod is provided with a limiting frame for rotating the lever relative to the mixing rod.

[0011] Furthermore, the connecting rod assembly includes a crank fixed to each stirring tooth shaft, and a connecting rod two connected to the other end of each crank; the mixing assembly two also includes a gear two fixedly mounted coaxially with one of the stirring tooth shafts; the other end of the push rod two is provided with a rack frame that meshes with the gear two.

[0012] Furthermore, the drive assembly includes a turntable coaxially fixedly mounted on the drive shaft and rotatably and sealingly connected to the bottom of the housing; a drive rod is provided below the turntable; the lifting assembly includes a second motor fixedly mounted on the housing, a driven plate and a lifting plate fixedly connected above and below and both sleeved on the drive shaft, and a gear and rack assembly with its input end connected to the second motor and its output end horizontally rotatably connected to the lifting plate; the driven plate is slidably connected to the drive rod below the turntable; the first push rod and the second push rod both slide through the turntable and are fixedly connected to the driven plate.

[0013] Furthermore, the mixing mechanism also includes a scraping assembly; the scraping assembly includes a scraper frame rotatably mounted inside the housing and attached to the bottom and side walls of the housing, a docking turntable rotatably mounted below the housing, and at least one pair of strong magnets correspondingly mounted on the scraper frame and the docking turntable; the bottom of the housing is made of a non-magnetic material; a plurality of docking rods are provided on the outer side of the docking turntable, and a lever is provided on the driven plate corresponding to each docking rod.

[0014] Furthermore, the discharge mechanism includes a discharge plate that is fixedly and sealed to the bottom of the housing, a switch plate that is slidably and sealed to the discharge plate, and a discharge pipe installed below the discharge plate.

[0015] Because the present invention adopts the above-described technical solution, the present invention has the following advantages:

[0016] 1. This invention achieves the switching between high-speed shearing and low-speed mixing modes through the coordinated design of the driving component, lifting component, mixing component one, and mixing component two in the mixing mechanism, effectively improving the mixing effect.

[0017] 2. By adding a scraping component to the mixing mechanism, the present invention avoids the adhesion of the suspending agent to the inner wall of the shell during low-speed mixing, thereby further improving the mixing effect. Attached Figure Description

[0037] Example:

[0038] like Figures 1-2 As shown, a mixing vessel for a suspension containing pyraclostrobin, fludioxonil, and terpineol includes a support 2 and a housing 1 disposed on the support 2. It also includes a mixing mechanism 3 sealed and installed on the housing 1, and a discharge mechanism 4 installed at the bottom of the housing 1. In this embodiment, the discharge mechanism 4 includes a discharge plate 41 sealed and fixedly installed at the bottom of the housing 1, a switch plate 42 sealed and slidably installed on the discharge plate 41, and a discharge pipe 43 installed below the discharge plate 41.

[0039] like Figures 3-6 As shown, the mixing mechanism 3 includes a drive assembly 31 that is sealed and installed on the housing 1 and whose drive shaft 313 extends into the housing 1, a mixing assembly 1 33 and a mixing assembly 2 34 that are radially distributed and staggeredly fixed on the drive shaft 313, and a lifting assembly 32 for driving the mixing assembly 1 33 and the mixing assembly 2 34 to perform a mixing mode.

[0040] Specifically, such as Figure 7 As shown, the drive assembly 31 includes a motor 312 fixedly mounted on the outer side of the bottom of the housing 1 via a mounting bracket 311, and a drive shaft 313 coaxially fixedly connected to the output shaft of the motor 312. A support plate 314 and a turntable 315 are coaxially fixedly mounted on the drive shaft 313, with the support plate 314 located inside the housing 1. The mixing assembly 33 and the mixing assembly 34 are radially distributed and staggeredly fixedly mounted on the support plate 314. The turntable 315 is rotatably and sealingly connected to the bottom of the housing 1, thereby forming a sealed space inside the housing 1.

[0041] Specifically, such as Figures 7-8 As shown, a drive rod is provided below the turntable 315; the lifting assembly 32 includes a second motor 321 fixedly mounted on the mounting bracket 311, a driven plate 324 and a lifting plate 323 fixedly connected above and below and both sleeved on the drive shaft 313, and a gear and rack assembly 322 whose input end is connected to the second motor 321 and whose output end is horizontally rotatably connected to the lifting plate 323; the driven plate 324 is slidably connected to the drive rod below the turntable 315;

[0042] Specifically, such as Figures 10-11 As shown, the mixing assembly 33 includes a mixing rod 331 fixedly installed on the support plate 314, a mixing rod 332 rotatably installed on the inner end of the mixing rod 331, a mixing rod 333 rotatably installed on the inner end of the mixing rod 332, a control rod 334 with one end rotatably connected to the mixing rod 333 and the other end rotatably and slidably connected to the mixing rod 232, and a top rod 335 with the upper end rotatably and slidably connected to the mixing rod 333 near the inner end and the lower end slidably passing through the turntable 315 and fixedly connected to the driven plate 324.

[0043] As a specific implementation of this embodiment, in order to improve the mixing effect during slow stirring, the mixing assembly 33 further includes several auxiliary rods 336 rotatably mounted on both sides of the stirring rod 331 and synchronously rotated through the connecting rod 337; a lever 338 rotatably mounted in the middle on both sides of the stirring rod 331 near the inner end and connected to the connecting rod 337 at its lower end; and a return spring 339 installed between the inner end of the stirring rod 331 and the upper end of the lever 338; the top rod 335 is provided with a limiting frame 3351 for rotating the lever 338 relative to the stirring rod 331; the lever 338 is always abutting against the limiting frame 3351 under the action of the return spring 339;

[0044] Working principle of mixing component 133:

[0045] When a low-speed mixing mode is required (such as...) Figures 1-7 In the state shown, the motor 321 of the lifting assembly 32 drives the lifting plate 323 to rise through the gear and rack assembly 322, which in turn drives the driven plate 324 to rise. The push rod 335 pushes the stirring rod 333 upward under the drive of the driven plate 324. When the stirring rod 333 rotates upward relative to the stirring rod 331 by a set angle, the stirring rod 332 starts to rotate upward relative to the stirring rod 331 under the drive of the stirring rod 333 and the control rod 334 until the set angle is reached. At the same time, during the upward pushing process of the push rod 335, the limit frame 3351 pushes the upper half of the lever 338 upward. The lever rotates under this action and drives the auxiliary rod 336 to rotate downward relative to the stirring rod 331 through the connecting rod 337 until the set angle is reached, thus completing the preparation of the low-speed stirring mode.

[0046] When a high-speed shear mixing mode is required (such as...) Figures 14-15 When in the state shown, the opposite action is performed, so that stirring rod 2 332 and stirring rod 333 both coincide with stirring rod 1 331; at the same time, during the downward movement of top rod 1 335, lever 338, under the action of return spring 339, gradually aligns all auxiliary rods 336 with stirring rod 1 331.

[0047] like Figures 12-13As shown, the mixing assembly 34 includes a stirring rod 341 fixedly mounted on a support plate 314, a plurality of stirring teeth 342 arranged rotatably on the stirring rod 341 from the inner end to the outer end and synchronously rotated through a connecting rod assembly 343, and a top rod 345 whose lower end slides through the turntable 315 and is fixedly connected to the driven plate 324, and whose upper end drives the connecting rod assembly 343 to move. In this embodiment, the connecting rod assembly 343 includes cranks 3432 fixed to the rotating shafts at both ends of each stirring tooth 342, and connecting rods 3431 connected to the other end of each crank 342. The mixing assembly 34 also includes a pair of gears 344 fixedly mounted coaxially with the rotating shaft of the stirring tooth 342 located at the innermost end. The top rod 345 has a rack frame 3451 that meshes with the gears 344.

[0048] Working principle of mixing component 234:

[0049] When a low-speed mixing mode is required (such as...) Figures 1-7 When the state shown is reached, the push rod 345 is pushed upward by the driven plate 324. At this time, the rack frame 3451 pushes the gear 344, which drives the innermost stirring tooth 342 to rotate. This, in turn, drives all the parts in the open state (such as...) through the connecting rod 3431. Figure 13 The stirring teeth 342 (as shown) gradually rotate inward toward the stirring rod 341 until they coincide with the stirring rod 341 (as shown). Figure 12 (as shown)

[0050] When a high-speed shear mixing mode is required (such as...) Figures 14-15 When the state shown is reached, the opposite action is performed, so that all stirring teeth 342 are in the open state (as shown). Figure 13 (As shown).

[0051] As a specific implementation of this embodiment, in order to further improve the mixing effect in low-speed stirring mode and prevent the suspending agent from adhering to the inner wall of the shell 1, such as Figure 6 and Figure 9 As shown, the mixing mechanism 3 also includes a scraper assembly 35; the scraper assembly 35 includes a scraper frame 351 rotatably mounted inside the housing 1 and attached to the bottom and side wall of the housing 1, a docking turntable 352 rotatably mounted below the housing 1, and two pairs of strong magnets 353 correspondingly mounted on the scraper frame 351 and the docking turntable 352; the bottom of the housing 1 is made of a non-magnetic material (such as aluminum alloy); the docking turntable 352 is provided with several docking rods 3521 on its outer side, and the driven plate 324 is provided with a lever 3241 corresponding to each docking rod 3521;

[0052] Working principle of scraper assembly 35:

[0053] When a low-speed mixing mode is required (such as...) Figures 1-7When the state shown is reached, the driven disk 324 rises to the set height. At this time, the lever 3241 cooperates with the docking rod 3521 on the outside of the docking turntable 352, so that when the drive assembly 31 works at low speed, the turntable 315 drives the driven disk 324 to rotate coaxially through the driving rod, thereby driving the docking turntable 352 to rotate synchronously. Finally, the scraper 351 achieves synchronous rotation under the action of two pairs of strong magnets 353, completing the scraping of the inner wall of the housing 1.

[0054] When a high-speed shear mixing mode is required (such as...) Figures 14-15 When the driven disk 324 descends to the set height (as shown), the lever 3241 is disconnected from the docking rod 3521 on the outside of the docking turntable 352. When the drive assembly 31 is working at high speed, the scraper assembly 35 is in a non-working state.

[0055] The working principle of this embodiment:

[0056] First, pyraclostrobin, fludioxonil, terpineol, deionized water and related additives are added into shell 1;

[0057] Second, activate the high-speed shearing and mixing mode to further crush and mix the raw materials;

[0058] Third, start the low-speed mixing mode to fully mix the raw materials;

[0059] Fourth, repeat steps two and three several times until fully mixed;

[0060] Fifth, the mixed suspension is discharged through the discharge mechanism 4.
