Description

Technical Field

[0001] This invention relates to the field of integrated water and fertilizer machines, specifically to an integrated water and fertilizer machine for precision fertilization. Background Technology

[0002] In agricultural production, water and fertilizer are indispensable core elements for crop growth, and their scientific application directly affects crop yield, quality, economic benefits, and environmental sustainability. Traditional irrigation and fertilization methods often suffer from low water resource utilization, severe fertilizer nutrient loss, and high labor intensity, not only increasing agricultural production costs but also potentially leading to ecological problems such as soil compaction and eutrophication due to excessive fertilization. With the development of modern agricultural technology, integrated water and fertilizer management technology has emerged. By organically combining irrigation and fertilization, it achieves precise supply of water and nutrients during crop growth, effectively improving water and fertilizer utilization efficiency and becoming an important technical means to promote water conservation, efficiency improvement, and green sustainable development in agriculture.

[0003] As a key piece of equipment for realizing integrated water and fertilizer technology, the integrated water and fertilizer machine integrates multiple functional units to achieve automated or semi-automated operation from water source extraction, fertilizer dissolution, ratio control to precise delivery. Typically, this type of equipment mainly consists of a water supply unit, a fertilizer dissolution and mixing unit, a ratio control unit, a water distribution network, and a control system. Its general operating process is as follows: First, the water supply unit draws water from sources such as rivers, wells, or reservoirs, and removes impurities through filters to prevent clogging; simultaneously, solid or liquid fertilizer is fully dissolved and stirred in the dissolution and mixing unit to form a uniform fertilizer solution; subsequently, the ratio control unit, according to the preset water and fertilizer concentration or crop requirements, precisely injects the fertilizer solution into the water flow in a certain proportion through mechanical or electronic control, forming a uniform water and fertilizer mixture; finally, the mixed water and fertilizer solution is transported to the root zone of crops in the field through the water distribution network for precise application through drip irrigation, sprinkler irrigation, or other methods.

[0004] In the process of mixing water and solid fertilizer, the integrated water and fertilizer machine mainly uses a tank, a motor, and a stirring shaft. After water and solid fertilizer are poured into the tank in the correct proportions, the motor drives the stirring shaft to mix the water and solid fertilizer evenly, facilitating precise delivery to the crop roots through pipes. While existing mixing methods can achieve relatively thorough mixing of water and solid fertilizer, the actual mixing process relies on the fertilizer's inherent water solubility. Additionally, some fertilizer clumps when damp, requiring the water flow from the stirring shaft to break up the clumps before dissolving them. However, existing mixing methods, whether unidirectional (where water easily forms eddies, causing clumps to be thrown to the tank wall by centrifugal force) or bidirectional turbulence-based mixing, suffer from the limited range of water flow that the stirring shaft can agitate, making it difficult to ensure sufficient collision of all water and fertilizer in a short time. In simple terms, the further away from the mixing axis, the less turbulent the water flow is compared to the closer to the mixing axis (this is even more obvious when comparing the turbulence of the water flow at the bucket wall and the center of the bucket). This means that clumps of fertilizer farther from the mixing axis are more difficult to break up by the water flow in a short time, and may even stick to the bucket wall. This requires extending the mixing time so that clumps of fertilizer far from the mixing axis can slowly flow into the mixing area with the relatively gentle water flow. However, this will obviously reduce the efficiency of water and fertilizer irrigation, and clumps of fertilizer stuck to the bucket wall may not be washed away by the water. Therefore, how to mix water and solid fertilizer more efficiently and thoroughly has become an urgent problem to be solved.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing precision fertilization integrated water and fertilizer machine. Summary of the Invention

[0006] The present invention addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. Specifically, the purpose of the present invention is to provide a precision fertilization water and fertilizer integrated machine to solve the problem mentioned in the background technology that the farther away from the stirring shaft the clump of fertilizer is from the water flow, the more difficult it is to break up in a short time, and it may even stick to the barrel wall.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a precision fertilization water and fertilizer integrated machine, including a control platform, a pipeline valve system and a mixing tank, and further including: a top cover set on the top of the mixing tank, a motor set in the middle of the top cover, a lifting component set above the top cover and driven by the motor, and a turbulence component that adapts its shape to fully collide and fuse water and fertilizer during lifting. The lifting assembly includes a reciprocating groove screw that passes through the top cover and is rotatably inserted into the bottom of the mixing tank, several sets of connecting blocks that are rotatably arranged on one side of the guide ring, and a screw block that is rotatably inserted into the connecting block at one end. The turbulence-inducing assembly includes a stirring shaft connected to the motor output end via a coupling at its top, a directional groove formed on the inner wall of the mixing tank, a guide ring movably disposed inside the mixing tank, a guide groove extending through the surface of the guide ring, a push plate hinged to the connecting block, and a paddle fixed in the middle of one end of the push plate.

[0008] Preferably, the lifting assembly further includes a limiting sleeve fixed to one side of the connecting block; The limiting sleeve is provided with several groups that are distributed in equal proportions; The limiting sleeve slides through the limiting upright in the middle; The two ends of the limiting rod are respectively fixed to the bottom surface of the top cover and the inner wall of the bottom end of the mixing tank.

[0009] Preferably, sprockets are fixed to the top of the reciprocating groove screw and the upper end of the stirring shaft; A chain is engaged on the outer wall of the sprocket; The sprockets and chains are each provided with several sets; Each set of chains has two sets of sprockets meshing at both ends.

[0010] Preferably, the reciprocating groove screw and screw block are provided in several groups of equal number and distributed in equal proportion; The other end of the wire block slides within a groove on the surface of the reciprocating screw.

[0011] Preferably, a limit slider is fixed on the other side of the guide ring; The limiting slider and the directional slide are each provided with several sets of the same number and distributed in equal proportions. The limiting slider slides inside the sliding groove; The directional chute consists of two sets of parallel longitudinal straight grooves and an inclined groove connecting the two ends of the two sets of longitudinal straight grooves. The two sets of inclined grooves are mirror images of each other.

[0012] Preferably, several sets of the connecting blocks are distributed proportionally on one side of the guide ring; A set of push plates is hinged between each pair of the connecting blocks.

[0013] Preferably, the push plate is provided in several groups that are equally distributed; A gap is left between each pair of push plates; The other end of the pusher plate is close to the stirring shaft, but the two do not contact each other.

[0014] Preferably, a number of double-edged crushing blades are fixed on one side of the push plate; Several groups of the aforementioned double-edged breaker blades are distributed at equal intervals in a linear array.

[0015] Preferably, the guide groove has several groups that are distributed in equal proportions; Each set of guide grooves corresponds to each set of paddles, and the paddles are movably inserted into the guide grooves; The two sides of the guide groove are set as inclined walls with the same inclination direction.

[0016] Preferably, the top and bottom ends of the guide ring and the connecting block are both set as inclined surfaces; The other side of the guide ring is in close contact with the inner wall of the mixing tank.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, during the continuous rotation of the stirring shaft, the water flow around the shaft center forms a vortex. Some of the water and fertilizer near the stirring shaft mix, while some of the clumped fertilizer is centrifugally thrown to the inner wall of the mixing tank by the vortex. The rotation of the stirring shaft drives the guide ring and push plate to move up and down repeatedly. When the push plate moves downward, it is "upturned". The water flow becomes more gentle towards the outer edge of the stirring range of the stirring shaft (but the water flow still has a velocity). At this time, the downward movement of the push plate will cause the water and fertilizer far away from the stirring shaft to be squeezed. Some of the water and fertilizer will be squeezed out into the gap between the two sets of push plates, forming a relatively strong jet. The clumped fertilizer will also be dragged by the water flow and hit the double-edged crusher, and after being crushed by the double-edged crusher, it will dissolve into the water. The other part of the water and fertilizer is forced to the stirring shaft by the push plate and mixed by the stirring of the stirring shaft.

[0018] 2. In this invention, the push plate is in a "drooping" position when it moves upward. This state reduces the squeezing force of the push plate on the water and fertilizer above it, preventing the water and fertilizer from being excessively "lifted" upward and overflowing. On the other hand, it can force the water and fertilizer away from the stirring shaft back towards the stirring shaft for mixing. In this invention, during the lifting and lowering process of the guide ring and the push plate, not only can most of the fertilizer adhering to the inner wall of the mixing tank be scraped into the mixing area, but the water flow can also be in various flow states such as vortex and jet. By using the different flow states of the water flow, all the water in the mixing tank is in a turbulent state, which allows the water and fertilizer to collide and blend with each other quickly. This effectively achieves the purpose of fully mixing water and fertilizer in a short time. Compared with the traditional stirring method, the stirring method of this invention is more efficient and thorough, which can shorten the water and fertilizer preparation time. At the same time, the more thorough mixing of water and fertilizer also improves the scientific concentration ratio of the water and fertilizer solution, which is conducive to crop growth.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1 to 12The present invention provides a technical solution: a precision fertilization water and fertilizer integrated machine, comprising a control platform 1, a pipeline valve system 2 and a mixing tank 3, characterized in that it further comprises: a top cover 4 disposed on the top of the mixing tank 3, a motor 5 disposed in the middle of the top cover 4, a lifting component disposed above the top cover 4 and driven by the motor 5, and a turbulence component that adapts its shape to fully collide and fuse water and fertilizer during lifting. In practical implementation, the connection, layout, and operation procedures of the control unit 1, pipeline valve system 2, and mixing tank 3 should remain consistent with existing technologies, as shown in the attached figure. Figure 1 As shown in the accompanying drawings, the present invention is only a simple illustration. Water can be transported to the mixing tank 3 through a pipeline after filtration. Fertilizer can be poured into the mixing tank 3 through the inlet. It should be noted that the inlet should be aligned with the center of the mixing tank 3 as much as possible to prevent fertilizer from accumulating on the surface of the push plate 14. In addition, since the present invention agitates all the water and fertilizer thoroughly, the fertilizer that clumps under the impact of the water flow will not easily stick to the reciprocating screw 8 and the sliding groove 13, and will not easily cause transmission jamming or restriction.

[0034] The lifting assembly includes a reciprocating groove screw 8 that passes through the top cover 4 and is rotatably inserted into the bottom of the mixing tank 3, several sets of connecting blocks 15 that are rotatably arranged on one side of the guide ring 11, and a screw block 20 that is rotatably inserted into the connecting block 15 at one end. The turbulence assembly includes a stirring shaft 10 connected to the output end of a motor 5 via a coupling at its top, a directional groove 13 formed on the inner wall of a mixing tank 3, a guide ring 11 movably disposed inside the mixing tank 3, a guide groove 12 extending through the surface of the guide ring 11, a push plate 14 hinged to a connecting block 15, and a paddle 18 fixed in the middle of one end of the push plate 14.

[0035] The lifting assembly also includes a limiting sleeve 19 fixed to one side of the connecting block 15; The limiting sleeve 19 is provided with several groups that are distributed in equal proportions; The middle sliding passage of the limiting sleeve 19 is through the limiting upright 9; The two ends of the limiting rod 9 are fixed to the bottom surface of the top cover 4 and the bottom inner wall of the mixing tank 3, respectively.

[0036] In specific implementation, the function of the limiting rod 9 is to allow the push plate 14 and the connecting block 15 to move vertically up and down without rotation. This provides an important condition for the independent rotation control of the guide ring 11 to swing the push plate 14. When the reciprocating screw 8 rotates, the screw block 20 slides along the groove on its surface and forces the connecting block 15 and the push plate 14 to move vertically back and forth.

[0037] A sprocket 6 is fixed to the top of the reciprocating screw 8 and the upper end of the stirring shaft 10. A chain 7 is engaged on the outer wall of the sprocket 6; Both sprocket 6 and chain 7 are provided with several sets; Each chain 7 has two sets of sprockets 6 meshing at both ends.

[0038] In specific implementation, as shown in the appendix Figure 1 To be continued Figure 4 As shown, each set of chains 7 corresponds to each set of reciprocating groove screws 8. Several sets of sprockets 6, except for those fixed to the top of the reciprocating groove screws 8, are all fixedly sleeved on the upper end of the stirring shaft 10. When one end of a set of chains 7 engages with a set of sprockets 6 fixed to the top of the reciprocating groove screw 8, the other end of this set of chains 7 should engage with another set of sprockets 6 fixed to the upper end of the stirring shaft 10. When the stirring shaft 10 rotates, it will drive the sprockets 6 on the surface of the stirring shaft 10 to rotate synchronously. Under the meshing action of the chains 7, the sprockets 6 fixed to the top of the reciprocating groove screw 8 at the corresponding position also begin to rotate. The attached diagram of this invention only uses two sets of chains 7 and reciprocating groove screws 8. In reality, the number and position of chains 7 and reciprocating groove screws 8 can be reasonably set according to different conditions such as liquid level and water pressure to ensure smooth lifting and lowering.

[0039] Both the reciprocating groove screw 8 and the screw block 20 are provided with several sets of the same number and distributed in equal proportion; The other end of the screw block 20 slides in the groove on the surface of the reciprocating screw 8.

[0040] In practical implementation, the grooves on the surface of the reciprocating screw 8 allow the screw block 20 to automatically turn downwards when sliding to the highest point and automatically turn upwards when sliding to the lowest point. As a mature existing technology, this invention will not elaborate further here. The design of the reciprocating screw 8 and the screw block 20 allows the push plate 14 to move up and down reciprocally without interruption or reverse rotation of the stirring shaft 10. It should be noted that the length of the groove on the surface of the reciprocating screw 8 should be matched with the length of the directional slide 13. That is, when the screw block 20 slides to the end of the groove of the reciprocating screw 8 and begins to change direction, the limiting slider 17 should also move to the end of the directional slide 13 and begin to prepare to change direction.

[0041] A limit slider 17 is fixed on the other side of the guide ring 11; Both the limiting slider 17 and the directional slide 13 are provided with several sets of the same number and distributed in equal proportion; The limiting slider 17 slides inside the guide groove 13; The directional chute 13 consists of two sets of parallel longitudinal straight grooves and an inclined groove connecting the two ends of the two sets of longitudinal straight grooves. The two sets of inclined grooves are mirror images of each other.

[0042] In specific implementation, with attachment Figure 6From the indicated orientation, the limiting slider 17 in this invention slides counterclockwise inside the sliding groove 13. When the limiting slider 17 slides to one of the sets of longitudinal straight grooves... Figure 6 When the longest set of longitudinal straight grooves reaches its highest point, the thread block 20 begins to drive the push plate 14 and connecting block 15 downwards, and the limiting slider 17 also moves downwards synchronously. However, the limiting slider 17 is affected by the inclined groove above the directional chute 13 and moves diagonally downwards, sliding into another set of longitudinal straight grooves. When the limiting slider 17 moves diagonally downwards, it drives the guide ring 11 to rotate counterclockwise, causing the push plate 14 to tilt upwards. When the limiting slider 17 slides to the lowest point of another set of longitudinal straight grooves, it is also affected by the inclined groove below and moves diagonally downwards, driving the guide ring 11 to rotate clockwise, causing the push plate 14 to droop, until the limiting slider 17 slides to the lowest point of one set of longitudinal straight grooves. Then, the thread block 20 begins to drive the guide ring 11 and push plate 14 upwards, and so on. It should be noted that in order to ensure that the limit slider 17 can switch smoothly between the two sets of longitudinal straight grooves during lifting, the size of the connection between the two sets of inclined grooves and the two sets of longitudinal straight grooves should be larger than the size of the limit slider 17, and the connection should be provided with an arc-shaped transition trajectory with a guiding function. For details, please refer to the existing track setting theory and actual products. This invention will not elaborate further here.

[0043] Several sets of connecting blocks 15 are distributed proportionally on one side of the guide ring 11; A push plate 14 is hinged between every two sets of connecting blocks 15.

[0044] The push plate 14 is provided with several groups that are distributed in equal proportions; A gap is left between every two sets of push plates 14; In practice, the gap between the push plates 14 can cause the liquid to jet when the push plates 14 press down on the liquid. Combined with the liquid impact that already has a unidirectional vortex, the liquid flow velocity of the jet will be significantly faster, resulting in a greater drag force. This can effectively drag the clumped fertilizer and crash it into the double-edged crusher 16.

[0045] The other end of the pusher plate 14 is close to the stirring shaft 10, but the two do not contact each other.

[0046] In practice, the push plate 14 and the stirring shaft 10 do not contact each other to prevent interference between their movements. However, the other end of the push plate 14 should be as close as possible to the blades of the stirring shaft 10 to greatly reduce the space for laminar flow of water and fertilizer, which helps to ensure that all water and fertilizer are in turbulent water flow.

[0047] Several sets of double-edged crushing blades 16 are fixed on one side of the push plate 14; Several sets of double-edged crushing blades 16 are distributed at equal intervals in a linear array.

[0048] In practice, the jet of water has a certain drag force, which will drag the clump of fertilizer to the gap of the push plate 14. The double-edged crushing blade 16 intercepts the path of these clumps of fertilizer, so that when the clumps of fertilizer collide with the double-edged crushing blade 16, the fertilizer is broken up and can be dissolved in the water.

[0049] The guide groove 12 has several groups that are distributed in equal proportions; Each set of guide grooves 12 corresponds to each set of paddles 18, and the paddles 18 are movably inserted into the guide grooves 12. The two sides of the guide groove 12 are set as inclined walls with the same inclination direction.

[0050] In specific implementation, with attachment Figure 11 and attached Figure 12 From the perspective shown, when the guide ring 11 rotates counterclockwise, the paddle 18 is squeezed by the inclined wall on one side and droops, while the push plate 14 at the corresponding position will tilt upward like a seesaw. Conversely, when the guide ring 11 rotates clockwise, the paddle 18 will be lifted, while the push plate 14 at the corresponding position will droop, thus achieving the purpose of controlling the swing direction of the push plate 14 by controlling the rotation mode of the guide ring 11.

[0051] The top and bottom ends of the guide ring 11 and the connecting block 15 are both set as bevels; The other side of the guide ring 11 is in close contact with the inner wall of the mixing tank 3.

[0052] In specific implementation, the inclined angle of the guide ring 11 and the connecting block 15 is consistent, and the connection between the two is kept as tight and flat as possible. The angle of the inclined surface is also kept as consistent as possible with the tilt angle of the push plate 14. That is, when the push plate 14 tilts up and down, the fertilizer mainly rushes upward from the bottom of the push plate 14, and when the push plate 14 tilts down and rises, the fertilizer mainly flows downward from the top of the push plate 14. In either state, it is not easy to provide dead corners for the fertilizer, and the guide ring 11 can effectively scrape off the fertilizer adhering to the inner wall of the mixing tank 3.

[0053] Working principle: When using this precision fertilization water and fertilizer integrated machine, first inject the pre-filtered water and fertilizer into the mixing tank 3 according to the required ratio. After starting the motor 5, the stirring shaft 10 drives the sprocket 6 to rotate. When the reciprocating groove screw 8 rotates, it drives the screw block 20 to slide along the groove on its surface. Under the pull of the screw block 20 and the limiting action of the limiting rod 9, the connecting block 15 rises and falls steadily and vertically. In the initial state, the push plate 14 should be kept in an upward or downward state, that is, the inclined wall of the guide groove 12 should be in a state of blocking the paddle 18. For example, when the push plate 14 is in a drooping state and located at the bottom of the mixing tank 3, the screw block 20 is located at the lowest point of the groove of the reciprocating screw 8, and the limiting slider 17 is located at the lowest point of the longest set of longitudinal straight grooves in the directional chute 13. When the reciprocating screw 8 rotates, the screw block 20 begins to change direction and drives the connecting block 15 to move upward. The push plate 14 remains in a drooping state and moves upward. While the guide ring 11 moves upward, it scrapes some of the fertilizer adhering to the inner wall of the mixing tank 3 into the mixing area. When the screw block 20 slides to the top of the groove of the reciprocating screw 8, it changes direction and moves downward again. Meanwhile, the limiting slider 17 is forced to move diagonally downward under the action of the uppermost inclined groove in the directional chute 13. The slider 17 drives the guide ring 11 to rotate counterclockwise, causing the paddle 18 to be pressed down by the guide groove 12 and the push plate 14 to tilt upward. Then the push plate 14 moves vertically downward. The vortex formed by the stirring shaft 10 throws some of the clumped fertilizer to the push plate 14. The water flow outside the center of the vortex is unidirectional and lacks collisions. The downward-moving push plate 14 forcibly squeezes this part of the water flow, so that part of it is pushed back into the stirring range of the stirring shaft 10 with fertilizer to continue mixing. The other part is sprayed out from the gap of the push plate 14. The sprayed water flow drags the remaining clumped fertilizer past the double-edged crusher 16, which crushes the fertilizer that impacts it.

[0054] When the limiting slider 17 moves to the lowest point of the shorter set of longitudinal straight grooves in the directional chute 13, as the wire block 20 drives the guide ring 11 to continue moving downward, the limiting slider 17 is forced to move diagonally downward again by the lower inclined groove in the directional chute 13. At this time, the limiting slider 17 drives the guide ring 11 to rotate clockwise, causing the paddle 18 to be lifted by the guide groove 12 and the push plate 14 to droop. Until the wire block 20 changes direction again and drives the push plate 14 to move upward, the push plate 14, while maintaining its drooping state, pushes the liquid above it back into the stirring area of ​​the stirring shaft 10. At the same time, the guide ring 11 moves upward again to scrape off the fertilizer attached to the mixing tank 3. This process is repeated until the water and fertilizer are evenly mixed. Finally, the machine 1 is operated to transport the mixed water and fertilizer solution in the mixing tank 3 to the crop area through the pipeline.

[0055] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
