Description

Technical Field

[0001] This utility model relates to the field of agricultural nutrient solution preparation, and in particular to an automatic nutrient solution preparation and dispensing device. Background Technology

[0002] In agricultural planting, plant tissue culture, and laboratory seedling cultivation, precise delivery of nutrient solutions is crucial for plant growth, and the quality of the nutrient solution delivery system directly affects the delivery efficiency. Currently, most nutrient solution delivery devices use closed pipelines to deliver nutrient solutions, either driven by pumps or by gravity.

[0003] However, this pipeline delivery method has obvious problems: Firstly, the nutrient solution contains many minerals and organic components, which easily adhere to the inner wall of the pipe after prolonged transport. This causes the inner diameter of the pipe to gradually decrease, affecting the stability of the nutrient solution flow. Moreover, the substances adhering to the pipe deteriorate and contaminate subsequently transported nutrient solution, disrupting the balance of nutrients.

[0004] On the other hand, the pipelines are closed, so operators cannot directly see the flow of the nutrient solution, its level, or whether there are any blockages or sedimentation issues. They can only judge by looking at the flow meter or the liquid output at the end. This leads to delayed detection of faults, making repairs both difficult and expensive.

[0005] In addition, while some devices attempt to alleviate pipe adhesion problems by adding cleaning components, this makes the equipment more complex and costly, and the residues in pipe corners and joints are still difficult to clean.

[0006] Based on this, we propose an automatic nutrient solution preparation and dispensing device. Utility Model Content

[0007] To address the technical problems of adhesion to the inner wall and difficulty in observation in existing pipeline transportation, this utility model provides an automatic nutrient solution dispensing and feeding device.

[0008] This utility model is achieved by the following technical solution: an automatic nutrient solution dispensing and feeding device, comprising a device body, a supporting scaffold fixedly connected to the bottom end of the device body, a supporting column fixedly connected to the top end of the supporting scaffold, a supporting plate fixedly installed at the top end of the supporting column, and a dispensing dish fixedly connected to the inner side of the supporting plate; the supporting column is located outside the dispensing dish, and the supporting column and the dispensing dish are limited by locking bolts.

[0009] The bottom of the mixing dish extends downwards to a fixed frame, which overlaps the bottom wall of the inlet pool. The fixed frame and the side wall of the inlet pool are rotatably connected by a through-shaft rod, and the inlet pool reciprocates around the through-shaft rod.

[0010] The mixing vessel is equipped with a stirring mechanism inside, and a reciprocating pushing mechanism is connected above the supporting scaffold. The stirring mechanism includes a drive motor, which is fixedly connected above the support plate. The output end of the drive motor is connected to a stirring rod, and a stirring paddle is fixedly connected to the surface of the stirring rod. The stirring rod passes through the mixing vessel.

[0011] The reciprocating drive mechanism includes a motor, which is fixedly connected to the outer edge of the supporting scaffold. The motor's output end is connected to a drive disc, and a connecting shaft block is fixedly connected to the surface edge of the drive disc. The outer side of the connecting shaft block integrally forms a motion shaft. A sliding shaft bracket is fixedly connected to the end of the motion shaft away from the connecting shaft block. A sliding block is fixedly fitted onto the surface of the sliding shaft bracket, and the sliding block slidably engages in a groove on the surface of the receiving frame. The bottom end of the receiving frame is fixedly connected to the surface edge of the supporting scaffold, and the motor's output shaft passes through the groove and connects to the drive disc. The liquid inlet tank is elongated and dish-shaped, with an inlet pipe connected to its end. A rubber stopper is installed at the connection between the inlet pipe and the liquid inlet tank.

[0012] As a further optimization of this utility model, the entire device integrates various components through the main body of the device, and the supporting scaffold serves as the bottom support structure, providing a stable installation foundation for the support column, reciprocating push mechanism, etc., ensuring that the components work together without interference during the stirring and liquid feeding process.

[0013] As a further optimization of this utility model, the automatic nutrient solution dispensing and feeding device achieves uniform mixing of nutrient solution through a stirring mechanism, drives the feeding tank to deflect back and forth with a reciprocating pushing mechanism to complete automatic feeding, and controls the dispensing rhythm through a baffle plate. The coordinated operation of all structures realizes automatic dispensing and precise delivery of nutrient solution.

[0014] As a further optimization of this utility model, when cleaning is required, simply pour cleaning water into the liquid inlet tank and repeatedly push the mechanism to clean the liquid inlet tank.

[0015] As a further optimization of this utility model, the nutrient solution is finally output through the inlet pipe at the end of the inlet pool. The rubber plug at the connection between the inlet pipe and the inlet pool can enhance the sealing performance and prevent leakage.

[0016] As a further optimization of this utility model, the stirring rod penetrates the interior of the mixing vessel, and the stirring paddle on its surface rotates synchronously with the rod to fully stir the nutrient solution raw materials in the mixing vessel, ensuring that minerals, organic components, etc. are mixed evenly and avoiding precipitation or component stratification.

[0017] As a further optimization of this utility model, the liquid preparation vessel is fixedly supported by a support plate, and the support plate is connected to the support scaffolding through a support column. The locking bolts between the support column and the liquid preparation vessel can enhance the structural stability and prevent shaking during stirring.

[0018] As a further optimization of this utility model, a baffle plate runs through the interior of the liquid preparation vessel, and a handle is fixedly connected to the outer edge of the baffle plate. The baffle plate runs through the interior of the liquid preparation vessel to obstruct the flow.

[0019] As a further optimization of this utility model, the baffle plate is pulled out by the handle. The baffle plate penetrates the interior of the mixing vessel, and its removal process can release the obstruction to the flow of nutrient solution, allowing the mixed nutrient solution to flow from the bottom of the mixing vessel into the inlet pool. If it is necessary to pause the inlet, the handle is pushed to reinsert the baffle plate into the mixing vessel, thereby blocking the flow of liquid and achieving rhythm control of the mixing and inlet.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. This utility model effectively solves the problem of adhesion and contamination of nutrient solution in traditional pipeline transportation. By adopting a long, dish-shaped inlet pool with a reciprocating deflection design, it replaces the closed pipeline as the main transportation method, reducing the adhesion of minerals and organic components to the inner wall, avoiding the impact of reduced pipeline inner diameter on flow stability, and reducing the risk of nutrient solution contamination caused by residual deterioration, thus ensuring the balance of nutrients.

[0022] 2. This utility model device improves the observability of nutrient solution delivery and the efficiency of troubleshooting. The open structure of the inlet tank allows operators to directly observe the flow, level, and sedimentation of the nutrient solution without relying on flow metering or end-point discharge judgment. This enables timely detection of blockages and other problems, shortens fault response time, and reduces maintenance difficulty and cost.

[0023] 3. This utility model simplifies the equipment structure and reduces operating costs. Compared with traditional devices with cleaning components, this utility model completes cleaning by driving the liquid inlet tank to move through a reciprocating push mechanism. It only requires pouring in cleaning water and repeating the operation to clean, eliminating the need for additional complex components, reducing equipment complexity and manufacturing costs, and facilitating maintenance.

[0024] 4. This utility model achieves precise and coordinated control of nutrient solution preparation and inlet. The stirring mechanism ensures uniform mixing of the nutrient solution, the baffle plate can flexibly control the inlet rhythm, and the reciprocating push mechanism drives the inlet pool to deliver the solution stably. The coordinated operation of each component improves the accuracy of solution preparation and the stability of inlet. It is suitable for scenarios with high requirements for nutrient solution delivery, such as agricultural planting and laboratory seedling cultivation. Attached Figure Description

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0034] Example 1:

[0035] Please combine Figures 1-6 This embodiment proposes an automatic nutrient solution preparation and feeding device, including a device body 1, a support scaffold 2 fixedly connected to the bottom end of the device body 1, a support column 3 fixedly connected to the top end of the support scaffold 2, a support plate 4 fixedly installed on the top end of the support column 3, and a dispensing dish 5 fixedly connected to the inner side of the support plate 4.

[0036] It should be noted that the support column 3 is located outside the liquid preparation vessel 5, and the support column 3 and the liquid preparation vessel 5 are limited by the locking bolt 31.

[0037] A fixing frame 51 extends downward from the bottom of the liquid preparation vessel 5. The fixing frame 51 is attached to the bottom wall of the liquid inlet pool 8. The fixing frame 51 and the side wall of the liquid inlet pool 8 are rotatably connected by a through shaft rod 52. The liquid inlet pool 8 reciprocates around the through shaft rod 52.

[0038] A further technical solution is that a baffle plate 53 runs through the interior of the liquid preparation vessel 5, and a handle 54 is fixedly connected to the outer edge of the baffle plate 53. The baffle plate 53 runs through the interior of the liquid preparation vessel 5 to obstruct the flow.

[0039] After the solution is prepared, the operator pulls the baffle plate 53 through the handle 54. The baffle plate 53 penetrates the interior of the solution preparation vessel 5. The removal process removes the obstruction to the flow of the nutrient solution, allowing the mixed nutrient solution to flow from the bottom of the solution preparation vessel 5 into the inlet pool 8. If it is necessary to pause the inlet, push the handle 54 to reinsert the baffle plate 53 into the solution preparation vessel 5, thereby blocking the flow of liquid and achieving rhythm control of solution preparation and inlet.

[0040] The mixing dish 5 is equipped with a stirring mechanism 6 inside, and a reciprocating pushing mechanism 7 is connected above the supporting scaffold 2. The stirring mechanism 6 includes a drive motor 61, which is fixedly connected above the support plate 4. The output end of the drive motor 61 is connected to a stirring rod 62, and a stirring paddle 63 is fixedly connected to the surface of the stirring rod 62. The stirring rod 62 passes through the mixing dish 5.

[0041] In the specific technical solution, the stirring mechanism 6 is the core component of the solution preparation. Its drive motor 61 is fixed above the support plate 4. After starting, it drives the stirring rod 62 to rotate through the output shaft. The stirring rod 62 penetrates the interior of the solution preparation vessel 5, and the stirring paddle 63 on its surface rotates synchronously with the rod, fully stirring the nutrient solution raw materials in the solution preparation vessel 5 to ensure uniform mixing of minerals, organic components, etc., and to avoid precipitation or component stratification. The solution preparation vessel 5 is fixedly supported by the support plate 4, which is connected to the support scaffold 2 through the support column 3. The locking bolts 31 between the support column 3 and the solution preparation vessel 5 can enhance the structural stability and prevent shaking during stirring.

[0042] The reciprocating drive mechanism 7 includes a motor 71, which is fixedly connected to the outer edge of the supporting scaffold 2. The output end of the motor 71 is connected to a drive disc 72. A connecting shaft block 73 is fixedly connected to the surface edge of the drive disc 72. The outer side of the connecting shaft block 73 integrally forms a motion shaft 74. A sliding shaft bracket 75 is fixedly connected to the end of the motion shaft 74 away from the connecting shaft block 73. A sliding block 76 is fixedly fitted onto the surface of the sliding shaft bracket 75, and the sliding block 76 is slidably engaged in a groove 78 on the surface of the receiving frame 77. The bottom end of the receiving frame 77 is fixedly connected to the surface edge of the supporting scaffold 2. The output shaft of the motor 71 passes through the groove 78 and connects to the drive disc 72.

[0043] More specifically, the reciprocating drive mechanism 7 provides power for the liquid inlet. The motor 71 is fixed to the outer edge of the supporting scaffold 2. After startup, it controls the rotation of the drive disc 72. The connecting shaft block 73 on the edge of the drive disc 72 rotates with the disc, driving the integrated motion shaft 74 to perform circular motion. The sliding shaft bracket 75 at the end of the motion shaft 74 drives the sliding block 76 to reciprocate within the groove 78 of the receiving frame 77. The receiving frame 77 is fixed to the surface of the supporting scaffold 2, providing guidance for the sliding and converting the circular motion into linear reciprocating motion. The liquid inlet pool 8 and the fixing bracket 51 at the bottom of the dispensing dish 5 are rotatably connected via a through-shaft rod 52. When the sliding block 76 reciprocates, the liquid inlet pool 8 reciprocates around the through-shaft rod 52, using the change in tilt angle to push the internal nutrient solution to the end.

[0044] A further technical solution involves an inlet tank 8 shaped like a long, narrow dish, with an inlet pipe 9 connected to its end. A rubber stopper is installed at the connection between the inlet pipe 9 and the inlet tank 8. The nutrient solution is ultimately output through the inlet pipe 9 at the end of the inlet tank 8. The rubber stopper at the connection between the inlet pipe 9 and the inlet tank 8 enhances the seal and prevents leakage.

[0045] A further technical solution involves simply pouring cleaning water into the liquid inlet tank 8 and repeatedly pushing the mechanism 7 to clean the liquid inlet tank 8 when cleaning is required.

[0046] In summary, the entire device integrates all components through the main body 1, with the supporting scaffold 2 serving as the bottom support structure, providing a stable installation foundation for the support column 3, reciprocating push mechanism 7, etc., ensuring that the components operate collaboratively without interference during stirring and liquid feeding. This automatic nutrient solution mixing and feeding device achieves uniform mixing of the nutrient solution through the stirring mechanism 6, and automatically feeds the liquid inlet tank 8 by driving the reciprocating push mechanism 7 to deflect back and forth. At the same time, the dispensing rhythm is controlled by the baffle plate 53. The coordinated operation of all structures achieves automatic dispensing and precise delivery of the nutrient solution.

[0047] Overview of the overall working principle of this utility model:

[0048] This automatic nutrient solution mixing and feeding device achieves uniform mixing of nutrient solution through stirring mechanism 6, and drives feeding tank 8 to reciprocate and deflect to complete automatic feeding through reciprocating push mechanism 7. At the same time, the mixing rhythm is controlled by baffle plate 53. All structures work together to achieve automatic mixing and precise delivery of nutrient solution.

[0049] The mixing operation of the stirring mechanism:

[0050] The stirring mechanism 6 is the core component of the solution preparation. Its drive motor 61 is fixed above the support plate 4. After starting, it drives the stirring rod 62 to rotate through the output shaft. The stirring rod 62 penetrates the interior of the solution preparation vessel 5, and the stirring paddle 63 on its surface rotates synchronously with the rod, thoroughly stirring the nutrient solution raw materials in the solution preparation vessel 5 to ensure uniform mixing of minerals, organic components, etc., and to avoid precipitation or component stratification. The solution preparation vessel 5 is fixedly supported by the support plate 4, which is connected to the support scaffold 2 through the support column 3. The locking bolts 31 between the support column 3 and the solution preparation vessel 5 can enhance the structural stability and prevent shaking during stirring.

[0051] Flow regulation of the baffle plate:

[0052] After the solution is prepared, the operator pulls the baffle plate 53 through the handle 54. The baffle plate 53 penetrates the interior of the solution preparation vessel 5. The removal process removes the obstruction to the flow of the nutrient solution, allowing the mixed nutrient solution to flow from the bottom of the solution preparation vessel 5 into the inlet pool 8. If it is necessary to pause the inlet, push the handle 54 to reinsert the baffle plate 53 into the solution preparation vessel 5, thereby blocking the flow of liquid and achieving rhythm control of solution preparation and inlet.

[0053] The reciprocating propulsion mechanism works in tandem with the liquid inlet tank:

[0054] The reciprocating drive mechanism 7 provides power for the liquid inlet. The motor 71 is fixed to the outer edge of the supporting scaffold 2. After starting, it controls the drive disc 72 to rotate. The connecting shaft block 73 on the edge of the drive disc 72 rotates with the disc, driving the integrated motion shaft 74 to perform circular motion. The sliding shaft bracket 75 at the end of the motion shaft 74 drives the sliding block 76 to slide back and forth in the groove 78 of the receiving frame 77. The receiving frame 77 is fixed to the surface of the supporting scaffold 2, providing guidance for the sliding and converting the circular motion into linear reciprocating motion. The liquid inlet pool 8 and the fixing bracket 51 at the bottom of the dispensing dish 5 are rotatably connected by the through shaft 52. When the sliding block 76 slides back and forth, the liquid inlet pool 8 reciprocates around the through shaft 52, using the change in tilt angle to push the internal nutrient solution to the end.

[0055] The nutrient solution is finally output through the inlet pipe 9 at the end of the inlet tank 8. The rubber plug at the connection between the inlet pipe 9 and the inlet tank 8 can enhance the sealing and prevent leakage.

[0056] When cleaning is required, simply pour cleaning water into the liquid inlet tank 8 and repeatedly push the mechanism 7 to clean the liquid inlet tank 8.

[0057] Structural stability assurance:

[0058] The entire device integrates all components through the main body 1, with the supporting scaffold 2 serving as the bottom support structure, providing a stable installation foundation for the support column 3, reciprocating push mechanism 7, etc., ensuring that the components work together without interference during the stirring and liquid feeding process.

[0059] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
