Description

Technical Field

[0001] This invention relates to the field of agricultural pesticide preparation technology, and in particular to an agricultural precision pesticide preparation device with independent storage of multiple feed groups. Background Technology

[0002] In agricultural pesticide preparation equipment, fertigation equipment, and chemical liquid preparation equipment, the mixing mechanism of the mixing tank is the core component for achieving full homogenization of agents, solvents, and additives. Currently, the mixing devices widely used in the industry generally adopt a fixed-angle paddle structure: that is, multiple sets of paddles are radially fixed on the mixing shaft, and the paddles are rigidly connected to the mixing shaft. The installation angle, tilt direction, and deployment posture of the paddles remain fixed after assembly. When the equipment is running, the mixing shaft drives the paddles to make a unidirectional circular rotation. The paddles maintain the same angle and the same flow field action mode throughout the entire mixing cycle. They cannot actively change the angle during rotation, nor can they form alternating fluid disturbance patterns according to mixing requirements.

[0003] The aforementioned traditional fixed-angle paddle stirring method has obvious technical defects in actual liquid preparation and mixing processes. The specific disadvantages and deficiencies are as follows: When a fixed-angle paddle rotates with the shaft, it can only apply a unidirectional tangential force to the liquid, causing the liquid to move in a circle along the inner wall of the tank, easily forming a stable overall vortex. Under this flow field, the liquid inside the tank only rotates in the same direction, making it difficult for effective convection and displacement to form between liquids at different heights and radial positions. Significant stirring blind zones will form in the sedimentation area at the bottom of the tank, the near-wall area, and the core vortex area at the center of the tank, leading to phenomena such as liquid stratification, clear liquid at the top, concentrated liquid at the bottom, and powder sedimentation. In agricultural pesticide applications involving the compounding of various forms of agents such as wettable powders, suspensions, and emulsifiable concentrates, a fixed-angle paddle cannot achieve homogeneous mixing throughout the tank, directly causing uneven pesticide concentration and affecting the application effect. Summary of the Invention

A rotating cylinder is rotatably installed inside the liquid preparation tank, with its top rotatably connected to the inner wall of the top of the liquid preparation tank; A fixed cylinder, in a ring array, is fixedly and continuously installed on the outside of the rotating cylinder, and multiple cylinders are provided; The movable cylinder is rotatably mounted at the end of the fixed cylinder away from the rotating cylinder; The paddle plate is fixedly installed at the end of the movable cylinder away from the fixed cylinder; A flipping assembly is located inside the fixed cylinder and is used to drive the movable cylinder to rotate.

[0006] In one embodiment, the flipping assembly includes a limiting rod that is movably disposed inside the movable cylinder. A curved groove is provided inside the movable cylinder, and one end of the limiting rod slides into contact with the curved groove.

[0007] In one embodiment, a movable rod is movably disposed inside the fixed cylinder, one end of the movable rod extending into the interior of the movable cylinder, and the other end being fixedly connected to the end of the limiting rod away from the curved groove.

[0009] In one embodiment, the paddle plate has a slot inside, and a movable plate is movably disposed in the slot. The movable plate has multiple through holes, the number of which is the same as the number of leak holes, and both have the same diameter.

[0010] In one embodiment, a fixing ring is fixedly sleeved on the outer side of the movable cylinder near one end of the paddle plate. A movable rod is axially symmetrically and movably disposed at both ends of the fixing ring. One end of the movable rod movably passes through one side of the paddle plate, and the end is located inside the slot and is fixedly connected to one side of the movable plate.

[0011] In one embodiment, a positioning spring is movably sleeved on the outer side of the movable rod. One end of the positioning spring is fixedly connected to one side of the movable plate, and the other end is fixedly connected to the inner wall of the slot.

[0012] In one embodiment, a ring is fixedly provided at the end of the fixed cylinder away from the rotating cylinder, and two arc-shaped plates are arranged in a circular array on the ring. An inclined groove is formed on the arc-shaped plate, and the end of the moving rod away from the movable plate is slidably embedded with the surface of the inclined groove and the arc-shaped plate.

[0013] In one embodiment, a rotating rod is movably disposed inside the rotating cylinder. The top of the rotating rod is rotatably connected to the inner wall of the liquid preparation tank. A positioning ring is fixedly sleeved on the outer side of the rotating rod. Multiple protrusions are arranged in an annular array on the positioning ring. An annular groove is formed in the middle of the positioning ring. The end of the movable rod away from the movable cylinder is slidably embedded in the surface of the annular groove.

[0014] In one embodiment, the number of protrusions is the same as the number of movable rods, and a recess is formed between two adjacent protrusions, with one end of the movable rod slidably embedded in the surface of the recess.

During counterclockwise rotation, the paddles maintain stable horizontal stirring, while during clockwise rotation, the paddles automatically change angles and alternately disturb the flow. The structure is simple and reliable, and dual-mode composite stirring can be achieved without electrical control. Attached Figure Description

[0026] The following is combined with Figures 1-10 This invention describes an agricultural precision dispensing device with independent storage of multiple feed groups.

[0027] like Figures 1-6 As shown, in one embodiment, an agricultural precision dispensing device with independent storage of multiple feed groups includes a dispensing tank 1 and multiple storage tanks 2 disposed above the dispensing tank 1, and further includes: Material pipe 3 connects the liquid mixing tank 1 and the storage tank 2, and multiple pipes are provided. Rotating cylinder 4 is rotatably installed inside liquid preparation tank 1, and its top is rotatably connected to the inner wall of the top of liquid preparation tank 1. Fixed cylinder 5, a ring array is fixedly and through-mounted on the outside of rotating cylinder 4, and multiple cylinders are set in number; The movable cylinder 6 is rotatably mounted on the fixed cylinder 5 at the end away from the rotating cylinder 4; The paddle 7 is fixedly installed at the end of the movable cylinder 6 away from the fixed cylinder 5; The flipping component 8 is located inside the fixed cylinder 5 and is used to drive the movable cylinder 6 to rotate.

[0028] Specifically, the multiple storage tanks 2 are independent of each other and can store different types of liquid and solid drugs respectively, realizing independent storage of multiple groups of drugs. The device also includes multiple feed pipes 3, which are connected between the liquid preparation tank 1 and the storage tank 2. Each group of storage tanks 2 delivers drugs to the liquid preparation tank 1 through an independent feed pipe 3, ensuring that the drug delivery process does not interfere with each other and avoids cross-contamination.

[0029] A rotating cylinder 4 is rotatably installed inside the liquid preparation tank 1. The top of the rotating cylinder 4 is rotatably connected to the inner wall of the top of the liquid preparation tank 1. The rotating cylinder 4 can rotate circumferentially along the central axis of the liquid preparation tank 1 under the drive of an external drive mechanism. Multiple fixed cylinders 5 are fixedly installed in a ring array on the outside of the rotating cylinder 4. The fixed cylinders 5 extend outward along the radial direction of the rotating cylinder 4 and rotate synchronously with the rotating cylinder 4.

[0030] Each fixed cylinder 5 has a movable cylinder 6 rotatably mounted at the end away from the rotating cylinder 4. The movable cylinder 6 can rotate circumferentially relative to the fixed cylinder 5. A paddle 7 is fixedly mounted at the end of the movable cylinder 6 away from the fixed cylinder 5. The paddle 7 rotates synchronously with the movable cylinder 6, realizing continuous alternating changes in the angle of the paddle 7. A flipping component 8 is provided inside the fixed cylinder 5. The flipping component 8 is connected to the movable cylinder 6 through a transmission, and is used to stably drive the movable cylinder 6 to rotate alternately in the forward and reverse directions, thereby driving the paddle 7 to continuously change its angle during rotation, forming a dynamically changing stirring flow field.

[0031] During actual drug preparation, the drugs in multiple storage tanks 2 are transported to the preparation tank 1 according to the mixing ratio through independent feed pipes 3; the rotating cylinder 4 drives the fixed cylinder 5, the movable cylinder 6 and the paddle 7 to rotate as a whole, stirring and mixing the drug solution in the preparation tank 1; at the same time, the flipping component 8 continuously drives the movable cylinder 6 to flip, so that the paddle 7 continuously changes its angle while rotating with the rotating cylinder 4, forming a combined shear turbulence and axial circulation flow field inside the preparation tank 1, which can quickly disperse the powdered drugs, avoid clumping and sedimentation, and drive the drug solution to circulate throughout the tank, eliminate the stirring blind zone, and improve the mixing uniformity. After stirring, the prepared drug solution can be output to the external application equipment through the discharge structure at the bottom of the preparation tank 1 to complete the precise drug preparation operation.

[0032] See Figures 3-6 As shown, in this embodiment, the flipping component 8 includes a limiting rod 81, which is movably disposed inside the movable cylinder 6. A curved groove 82 is provided inside the movable cylinder 6, and one end of the limiting rod 81 slides and fits into the curved groove 82.

[0033] Specifically, the limiting rod 81 is movably installed inside the movable cylinder 6, and the inner wall of the movable cylinder 6 is provided with a curved groove 82. One end of the limiting rod 81 slides and fits into the curved groove 82. When the rotating cylinder 4 drives the fixed cylinder 5 and the movable cylinder 6 to revolve as a whole, the limiting rod 81 and the curved groove 82 cooperate to drive each other, so that the movable cylinder 6 continuously rotates relative to the fixed cylinder 5, thereby driving the paddle 7 to continuously change its angle while revolving, forming a constantly changing stirring flow field inside the liquid mixing tank 1.

[0034] See Figure 5 and Figure 6As shown, in this embodiment, a movable rod 83 is movably disposed inside the fixed cylinder 5. One end of the movable rod 83 extends into the interior of the movable cylinder 6, and the other end is fixedly connected to the end of the limiting rod 81 away from the curved groove 82.

[0035] Specifically, a movable rod 83 is movably installed inside the fixed cylinder 5. One end of the movable rod 83 extends into the interior of the movable cylinder 6, and the end of the movable rod 83 is fixedly connected to the end of the limiting rod 81 away from the curved groove 82. The movable rod 83 can reciprocate along the axial direction of the fixed cylinder 5, thereby driving the limiting rod 81 to move synchronously, so that the limiting rod 81 always maintains a stable sliding contact with the curved groove 82. Under the drive of the movable rod 83, the limiting rod 81 can smoothly drive the curved groove 82, so that the movable cylinder 6 drives the paddle plate 7 to complete a continuous angle flipping action.

[0036] See Figure 4 As shown, in this embodiment, the surface of the paddle plate 7 is provided with a plurality of holes 71, which penetrate the paddle plate 7.

[0037] Specifically, the surface of the paddle plate 7 is provided with multiple holes 71. The holes 71 completely penetrate the paddle plate 7 along the thickness direction, so that the liquid medicine can flow through the holes 71 during the stirring process, forming turbulence to improve the mixing effect.

[0038] See Figures 4-6 As shown, in this embodiment, the paddle plate 7 has a slot 72 inside, and a movable plate 9 is movably arranged in the slot 72. Multiple through holes 91 are opened through the movable plate 9. The number of through holes 91 is the same as the number of leakage holes 71, and the diameter of the two is equal.

[0039] Specifically, when the through hole 91 on the movable plate 9 aligns with the drain hole 71 on the paddle 7, the drain hole 71 is in an open state. In this state, the paddle 7 remains horizontal and follows the rotating cylinder 4 in revolution. The liquid medicine is vertically cut through the holes, forming a fine turbulent jet. The horizontal flow method can achieve gentle and uniform stirring, avoiding the high-speed solid paddle 7 from hitting the liquid medicine to generate foam or damage the structure of the active pharmaceutical ingredient particles. It can quickly tear and evenly spread newly added powder and adjuvants, preventing excessively high local drug concentrations. When the movable plate 9 is moved along the slot 72 so that the through hole 91 and the drain hole 71 are staggered, the area on the movable plate 9 without the through hole 91 aligns with the drain hole 71 and... When the leak 71 is completely blocked, the paddle 7 can alternate between horizontal and vertical states as it rotates with the rotating cylinder 4. When the paddle 7 is in the vertical state and the leak 71 is blocked, it forms a solid pusher plate with a large radial thrust, which can throw the liquid near the tank wall toward the center of the tank and form a strong vertical convection circulation, which fully stirs up the powder deposited at the bottom of the tank. When the paddle 7 is in the horizontal state and the leak 71 is open, it forms a perforated turbulent flow again, which performs secondary fine shearing on the high-concentration liquid in the center area of ​​the tank, thereby completely eliminating the dead corner of stirring in the tank, so that the liquid can complete the entire process of being rolled up, torn apart and re-fused in sequence, which significantly improves the mixing uniformity and dosing accuracy.

[0040] See Figure 5 As shown, in this embodiment, a fixed ring 10 is fixedly sleeved on the outer side of the movable cylinder 6 near the paddle plate 7. A movable rod 11 is axially symmetrically and movably installed through both ends of the fixed ring 10. One end of the movable rod 11 movably passes through one side of the paddle plate 7, and the end is located inside the slot 72 and is fixedly connected to one side of the movable plate 9.

[0041] Specifically, the movable rod 11 can move laterally along its own axis, thereby driving the movable plate 9 to slide smoothly within the slot 72, realizing the alignment or offset of the through hole 91 and the drain hole 71, flexibly and reliably adjusting the open and closed state of the drain hole 71, ensuring smooth and stable switching of the opening and closing of the drain hole 71, improving the controllability of the stirring flow field, and the fixed ring 10 provides support for the movable rod 11.

[0042] See Figure 5 As shown, in this embodiment, a positioning spring 12 is movably sleeved on the outside of the moving rod 11. One end of the positioning spring 12 is fixedly connected to one side of the moving plate 9, and the other end is fixedly connected to the inner wall of the slot 72.

[0043] Specifically, a positioning spring 12 is movably sleeved on the outer side of the moving rod 11. One end of the positioning spring 12 is fixedly connected to one side of the moving plate 9, and the other end is fixedly connected to the inner wall of the slot 72. The positioning spring 12 can provide a stable reset force for the moving plate 9, reliably drive the moving plate 9 to automatically return to the initial position, realize the precise reset of the opening and closing state of the leakage hole 71, ensure that the moving plate 9 moves back and forth smoothly and is accurately positioned, and improve the stability and consistency of the stirring mechanism operation.

[0044] See Figures 4-6 As shown, in this embodiment, a ring 13 is fixedly installed at the end of the fixed cylinder 5 away from the rotating cylinder 4. Two arc-shaped plates 14 are arranged in a ring array on the ring 13. An inclined groove 141 is opened on the arc-shaped plate 14. The end of the moving rod 11 away from the movable plate 9 is slidably embedded in the surface of the inclined groove 141 and the arc-shaped plate 14.

[0045] Specifically, when the movable cylinder 6 rotates, it drives the fixed ring 10 to rotate synchronously. The rotation of the fixed ring 10, in turn, drives the moving rod 11 to rotate together. During the rotation of the moving rod 11, it slides smoothly along the inclined groove 141 on the arc plate 14. When the moving rod 11 moves upward along the inclined groove 141, it moves laterally towards the inside of the groove 72, simultaneously pushing the movable plate 9 to slide within the groove 72, so that the leakage hole 71 and the through hole 91 are misaligned, thus covering the leakage hole 71. During this process, the positioning spring 12 is stretched and stores elastic force. Similarly, when the fixed ring 10 rotates in the opposite direction, the moving rod 11 slides downward along the inclined groove 141, driving the moving rod 11 to move laterally in the opposite direction. At this time, the positioning spring 12 releases its elastic force, assisting the movable plate 9 to move in the opposite direction to the initial position, so that the leakage hole 71 and the through hole 91 are precisely aligned, and the leakage hole 71 returns to the open state. The entire structure achieves automatic switching of opening and closing of the leakage hole 71 through mechanical linkage, without the need for additional power drive. The action is smooth and continuous, and it accurately matches the rhythm of the paddle plate 7 angle change, effectively improving the synchronization and stability of the stirring flow field switching, thereby enhancing the uniformity of the drug solution mixing. At the same time, the structure is simple, has a low failure rate, and is suitable for the long-term stable operation of agricultural drug dispensing.

[0046] See Figure 8 and Figure 9 As shown, in this embodiment, a rotating rod 15 is movably arranged inside the rotating cylinder 4. The top of the rotating rod 15 is rotatably connected to the inner wall of the liquid preparation tank 1. A positioning ring 16 is fixedly sleeved on the outside of the rotating rod 15. Multiple protrusions 17 are arranged in a ring array on the positioning ring 16. A ring groove 161 is opened in the middle of the positioning ring 16. The end of the movable rod 83 away from the movable cylinder 6 is slidably embedded in the surface of the ring groove 161.

[0047] Specifically, in this application, the rotating cylinder 4 drives the fixed cylinder 5 and the paddle 7 to rotate clockwise and counterclockwise alternately. When the rotating cylinder 4 rotates clockwise around the rotating rod 15, the rotating rod 15 remains stationary. At this time, the positioning ring 16 also remains stationary. The movable rod 83 slides along the annular groove 161 opened on the surface of the positioning ring 16. Since multiple protrusions 17 are opened on the outside of the positioning ring 16, the surface of the annular groove 161 is also uneven. During the rotation, one end of the movable rod 83 will slide along the uneven surface of the annular groove 161. The movable rod 83 itself will move laterally back and forth, driving the limiting rod 81 to slide back and forth along the curved groove 82, realizing the reciprocating rotation of the movable cylinder 6 and the paddle 7. The paddle 7 will switch back and forth between horizontal and vertical states. When the paddle 7 is in the horizontal state, the leakage hole 71 is in the open state. When the paddle 7 becomes vertical, the leakage hole 71 is in the blocked state, which can improve the mixing quality of the medicine.

[0048] See Figure 9 As shown, in this embodiment, the number of protrusions 17 is the same as the number of movable rods 83, and a recess 18 is formed between two adjacent protrusions 17. One end of the movable rod 83 is slidably embedded in the surface of the recess 18.

[0049] Specifically, when one end of the movable rod 83 is located in the groove, the leakage hole 71 is aligned with the through hole 91. When the movable rod 83 moves along the annular groove 161 from the recess 18 to the protrusion 17 during rotation, the movable rod 83 will move laterally, causing the movable plate 9 to move, so that the leakage hole 71 is not aligned with the through hole 91, thus blocking the leakage hole 71.

[0050] See Figure 7 and Figure 10 As shown, in this embodiment, a collar 19 is fixedly sleeved on the outside of the rotating rod 15. A horizontal groove 191 is opened on one side of the collar 19. A stop block 20 is movably arranged in the horizontal groove 191. The end of the stop block 20 is fixedly connected to the inner wall of the horizontal groove 191 by a return spring 21. A push block 22 is fixedly arranged on the inner wall of the rotating cylinder 4. The push block 22 and the stop block 20 are movably abutted.

[0051] Specifically, when the rotating cylinder 4 rotates clockwise, the stop block 20 will not obstruct the push block 22, and the rotating rod 15 remains stationary. At this time, the movable rod 83 will slide along the uneven annular groove 161 on the surface of the positioning ring 16, and the movable rod 83 itself will move laterally back and forth, so that the paddle 7 can also rotate on its own axis during the revolution, adjusting its own stirring angle. After rotating clockwise a certain number of times, the rotating cylinder 4 rotates counterclockwise. During this process, the push block 22 will drive the stop block 20, the positioning ring 16, and the rotating rod 15 to rotate synchronously. At this time, the movable rod 83 is located at the recess 18, the paddle 7 is in a horizontal state, and the leakage hole 71 is in an open state. Maintaining this state, the rotating rod 15 rotates synchronously with the rotating cylinder 4. Therefore, the movable rod 83 and the positioning ring 16 remain relatively stable, and the movable rod 83 does not move laterally. 7. Maintaining a horizontal state to agitate the liquid; In this application, the paddle plate 7 maintains a horizontal posture throughout the counterclockwise rotation phase and controls the orifice 71 to be in an open state. Through turbulent flow, the liquid is finely dispersed and homogenized, avoiding damage to the agent structure and splashing. During the clockwise rotation phase, the posture of the paddle plate 7 alternates between horizontal and vertical states, synchronously driving the orifice 71 to alternately open and close. When the paddle plate 7 is vertical, the orifice 71 is covered to form a complete push surface, generating axial forced circulation. When the paddle plate 7 is horizontal, the orifice 71 is open to restore turbulent shearing. This ensures both gentle dispersion of the agent in the initial stage and completes the elimination of stirring blind zones and laminar layers through the alternating flow patterns in the reverse phase, achieving all-round and efficient mixing of large-volume liquid, and significantly improving the uniformity and consistency of agricultural agent preparation.

[0052] See Figure 7 and Figure 10 As shown, in this embodiment, an arc-shaped groove 201 is provided on one side of the stop block 20, and an abutment groove 221 is provided on the side of the push block 22 that is close to the stop block 20. The abutment groove 221 and the arc-shaped groove 201 are in movable contact.

[0053] Specifically, in the initial state, the end of the push block 22 without the abutment groove 221 is in contact with the end of the stop block 20 without the arc-shaped groove 201. When the rotating cylinder 4 rotates clockwise, the push block 22 will not push the stop block 20 to rotate. When the push block 22 rotates one revolution faster, its abutment groove 221 part will abut against the arc-shaped groove 201 of the stop block 20, thereby pushing the stop block 20 to move laterally inward and compressing the return spring 21. When the push block 22 rotates to one side of the stop block 20, it loses its abutment. The limiting function of groove 221 causes the stop block 20 to move to the outer side of the transverse groove 191 under the action of the return spring 21, returning to the initial state. That is, when the rotating cylinder 4 rotates clockwise, the collar 19 and the rotating rod 15 will not rotate. Similarly, when the rotating cylinder 4 rotates counterclockwise, the push block 22 will drive the stop block 20 and the collar 19 to rotate counterclockwise together. At this time, the movable rod 83 and the positioning ring 16 are in a relatively static state, and the state of the paddle plate 7 will not change.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
