Description

Technical Field

[0001] This invention belongs to the field of water and fertilizer processing technology, specifically a sealed water and fertilizer synthesis device with pressure regulation. Background Technology

[0002] Chemical fertilizers are produced industrially through chemical reactions and can rapidly promote plant growth. Water-fertilizer synthesis equipment is an important technical approach to achieve water-saving irrigation and efficient water and fertilizer management. The research on integrated water and fertilizer cultivation technology and supporting facilities for cash crops such as vegetables and fruit trees, as well as grain crops such as wheat and corn, is receiving increasing attention. Currently, water-fertilizer synthesis equipment mixes fertilizer and water according to the fertilizer-water ratio and then transports it to the field through pipelines.

[0003] However, some chemical fertilizers are highly water-soluble and can permeate into water, allowing them to be piped to fields for spraying and irrigation. But some organic fertilizers, with their larger particles or potential lumps, are not easily soluble in water and can clog pipes, nozzles, and drippers. The presence of these less water-soluble organic fertilizers can also cause stratification in the mixing tank, resulting in uneven concentrations. This can lead to the discharged liquid having a concentration that does not meet standards. If the discharged liquid is too concentrated, it can damage crops; if it is too diluted, it can reduce the effectiveness of irrigation.

[0004] In view of this, in order to improve the above-mentioned technical problems, the present invention provides a sealed water and fertilizer synthesis device with pressure regulation, which improves the above-mentioned technical problems. Summary of the Invention

[0005] The technical problem this invention aims to solve is as follows: Currently, some chemical fertilizers are highly water-soluble and can permeate into water, then be transported to fields through pipelines for spraying and irrigation. However, some organic fertilizers have larger particles or may contain lumps, making them difficult to dissolve in water and prone to clogging pipes, nozzles, and drippers. Furthermore, the presence of these water-insoluble organic fertilizers can easily lead to stratification in the mixing tank, resulting in uneven concentrations. This causes the discharged liquid to have a concentration that does not meet the standard values. If the discharged liquid has an excessively high concentration, it will damage crops; if the discharged liquid has an excessively low concentration, it will reduce the effectiveness of water and fertilizer irrigation.

[0006] The present invention provides a sealed water and fertilizer synthesis device with pressure regulation, the sealed water and fertilizer synthesis device with pressure regulation includes: a sealed tank, a diversion tank, a water inlet pipe, an impeller, a grinding unit, a stirring and detection unit, and a motor;

[0007] The sealed barrel is a cylindrical barrel structure with both ends closed;

[0008] The drainage bucket is fixedly installed on the upper surface of the sealed bucket;

[0009] The water inlet pipe passes through one side of the diversion bucket, and the water inlet pipe is fixedly connected to the diversion bucket;

[0010] The grinding unit is installed on the top of the sealed barrel and is used to grind lumpy fertilizer that is not easily soluble in water into powder.

[0011] The stirring detection unit is installed inside the sealed barrel and located below the grinding unit. The stirring detection unit is used to detect the concentration of the mixture while stirring the water-fertilizer mixture.

[0012] The motor is fixedly installed on the inner wall of the diversion tank, and the motor is used to provide power to the stirring detection unit.

[0013] Compared to existing technologies where some lumpy fertilizers are difficult to dissolve in water during the mixing of water and fertilizer, leading to uneven concentration of the water-fertilizer mixture and ineffective fertilizer utilization, thus reducing the fertilization effect on crops, this invention incorporates a grinding unit that utilizes water flow as a power source. This effectively utilizes water energy and saves resources. The grinding unit grinds lumpy or granular fertilizers into powder, and the accompanying water flow during grinding ensures that the fertilizer is initially mixed with the water, improving the mixing effect. The system is equipped with a stirring and detection unit. When fertilizer and water are being stirred, the changes in resistance experienced by the stirring element can detect the concentration of the mixture at different levels within the sealed container. Feedback is displayed on the screen on the sealed container, allowing for timely addition of water or fertilizer to ensure the concentration of the water-fertilizer mixture in the sealed container reaches the specified value. This guarantees the fertilization effect on plants and improves the practicality of the water-fertilizer synthesis equipment. Simultaneously, the grinding unit grinds the fertilizer and stirs it with the water through the stirring element, further homogenizing the concentration of the mixture in the sealed container and improving irrigation efficiency.

[0014] Preferably, the grinding unit includes: a first rotating shaft, an upper grinding disc, a lower grinding disc, and a discharge hole;

[0015] The first rotating shaft passes through the center of the impeller and is fixedly connected to the impeller. The first rotating shaft passes downward through the upper surface of the sealing barrel. The first rotating shaft is rotatably connected to the sealing barrel. The motor is located above the first rotating shaft. The output shaft of the motor is fixedly connected to the first rotating shaft.

[0016] The upper grinding disc is located below the impeller and on the first rotating shaft. The upper grinding disc is fixedly connected to the first rotating shaft. The end of the upper grinding disc away from the impeller is set as a conical structure. The upper grinding disc is rotatably connected to the diversion bucket through a bracket.

[0017] The lower grinding disc is located below the upper grinding disc and is fixedly connected to the sealing barrel. A tapered groove is provided on the end face of the lower grinding disc near the upper grinding disc, and there is a gap between the upper grinding disc and the lower grinding disc.

[0018] The discharge hole is located on the end face of the lower grinding disc away from the upper grinding disc.

[0019] Preferably, a connecting frame is fixedly connected to the end face of the lower grinding disc away from the upper grinding disc. The connecting frame is fixedly connected to the sealing barrel through an annular frame. A conical disc is provided inside the connecting frame. The conical disc is rotatably connected to the connecting frame. The tip of the conical disc faces the upper grinding disc. Multiple centrifugal holes are opened at the bottom end of the connecting frame.

[0020] Preferably, the stirring detection unit includes: a second rotating shaft, a mounting ring, a stirring rod, and an angle sensor;

[0021] The second rotating shaft passes through the discharge hole and is located below the upper grinding disc. The second rotating shaft is fixedly connected to the upper grinding disc, and the conical disc is fixedly installed on the second rotating shaft.

[0022] The mounting ring is provided in multiple ways, and the multiple mounting rings are axially and sequentially sleeved on the second rotating shaft, and the multiple mounting rings are rotatably connected to the second rotating shaft;

[0023] The stirring rods are provided in multiple staggered arrangement on both sides of the second rotating shaft, and the stirring rods are fixedly connected to the mounting ring;

[0024] The angle sensor is located between the conical disk and the stirring rod, and the angle sensor is fixedly connected to the conical disk.

[0025] When mixing water and fertilizer, some organic fertilizer particles are large and not easily soluble in water, which can easily lead to uneven mixing. Therefore, when adding water and fertilizer, water is first pumped into the inlet tank through the inlet pipe. Since the inlet pipe is positioned towards the impeller blades, the water flowing into the inlet tank drives the impeller to rotate. The rotation of the impeller drives the upper grinding disc to rotate through the No. 1 shaft. At the same time, the operator adds fertilizer into the gap between the upper and lower grinding discs. The upper grinding disc rotates while the lower grinding disc remains stationary. Therefore, when the upper grinding disc rotates, it grinds the fertilizer located in the gap into smaller particles or powder. At the same time, water continuously flows into the diversion tank from the inlet pipe and flows downward through the gap between the upper and lower grinding discs. Therefore, after the fertilizer is ground, it is mixed with the water flow. After the fertilizer and water are initially mixed, the mixture falls through the discharge hole into the cavity formed by the connecting frame and the conical disc. The initially mixed water-fertilizer mixture should flow out through the centrifuge hole opened at the connecting frame and enter the sealed tank.

[0026] When the upper grinding disc rotates, it drives the second rotating shaft to rotate, which in turn drives the conical disc to rotate. When the conical disc rotates, it generates centrifugal force on the water-fertilizer mixture in the cavity formed by the connecting frame and the conical disc, causing some of the mixture to be thrown out through the centrifugal holes and then sprinkled downwards into the sealed bucket, further improving the water-fertilizer mixing effect.

[0027] After the fertilizer and water flow into the sealed container, the controller starts the motor. The motor output shaft rotates, which drives the first rotating shaft to rotate. The first rotating shaft rotates, which drives the upper grinding disc to rotate. The upper grinding disc rotates, which drives the second rotating shaft to rotate. Since the mounting ring is rotatably connected to the second rotating shaft, and the stirring rod installed on the second mounting ring does not contact the inner wall of the sealed container, there is a gap between the two. Therefore, the stirring rod is not restricted at this time and will follow the second rotating shaft under the action of friction and torque. If the concentration of the mixture formed by the fertilizer and water in the sealed container is uneven at this time, multiple layers of mixture with different concentrations will appear in the sealed container. This is because multiple stirring rods are arranged in multiple layers and staggered on both sides of the second rotating shaft.

[0028] Therefore, when the stirring rod is stirring in the high-concentration water-fertilizer mixture, it experiences greater resistance. The resistance of the stirring rod offsets most of the friction and torque generated by the No. 2 rotating shaft. At this time, there is a large speed difference between the stirring rod with greater resistance and the No. 2 rotating shaft, and the speed of the stirring rod with greater resistance is lower than that of the No. 2 rotating shaft.

[0029] If the stirring rod is stirring in the water-fertilizer mixture with a concentration level that meets the standard, and the resistance it experiences and the friction and torque generated by the No. 2 rotating shaft are at the standard value, then the stirring rod will rotate synchronously with the No. 2 rotating shaft, and the angle change of the stirring rod at this time will be at the standard value.

[0030] When the stirring rod is stirring in the low-concentration layer of the water-fertilizer mixture, it experiences less resistance compared to the stirring rod in the high-concentration layer. The resistance of the stirring rod with less resistance offsets a smaller portion of the friction and torque generated by the second rotating shaft. At this point, there is a small speed difference between the stirring rod with less resistance and the second rotating shaft; that is, the stirring rod with less resistance rotates faster than the stirring rod with greater resistance. Consequently, the angle change values ​​of both the stirring rods in the higher and lower concentration layers are greater than the standard values, and the angle change value of the stirring rod in the higher concentration layer is greater than that of the stirring rod in the lower concentration layer. At this time, the angle sensor feeds back the angle change signals of the stirring rods in different layers, which are then displayed on the screen on the sealed container. Water or fertilizer is added promptly to ensure that the concentration of the water-fertilizer mixture in the sealed container reaches the specified value, guaranteeing the fertilization effect on the plants and improving the practicality of the water-fertilizer synthesis equipment.

[0031] Simultaneously, the grinding unit grinds the fertilizer, and the stirring rod mixes the fertilizer with water to further homogenize the concentration of the mixture in the sealed tank, thereby improving the irrigation effect.

[0032] Preferably, a scraper is fixed to the end of the stirring rod away from the mounting ring, and the end of the scraper away from the stirring rod contacts the inner wall of the sealed bucket. The scraper is made of elastic material. When the stirring rod rotates, it drives the scraper to rotate. When the scraper rotates, it scrapes against the inner wall of the sealed bucket, thereby scraping off some of the fertilizer adhering to the inner wall of the sealed bucket and improving the uniformity of water-fertilizer mixing.

[0033] Meanwhile, the scraper is made of elastic material to avoid restricting the rotation of the stirring rod and to prevent the scraper from generating large rotational resistance on the stirring rod, which would affect the concentration detection effect of the water-fertilizer mixture.

[0034] Preferably, a feed pipe runs through the diversion bucket, with one end of the feed pipe located inside the diversion bucket above the gap between the upper and lower grinding discs, making it convenient for workers to add fertilizer through the feed pipe into the gap between the upper and lower grinding discs.

[0035] Preferably, the sealed water-fertilizer synthesis device with pressure regulation further includes: a flow regulation unit;

[0036] The flow regulating unit is located at the bottom of the sealed container, and the flow regulating unit is used to regulate the discharge volume of the mixture.

[0037] Preferably, the flow regulating unit includes: an inner cylinder, an outer cylinder, an inner hole, an outer hole, and a discharge pipe;

[0038] The inner cylinder is a barrel-shaped structure with an opening at one end and a closed end. The inner cylinder is fixed to the bottom of the sealed barrel, and the inner cylinder is fixed to the sealed barrel and is connected to the sealed barrel.

[0039] The outer cylinder is a barrel-shaped structure with an opening at one end and a closed end. The outer cylinder is sleeved on the outside of the inner cylinder. The upper end of the outer cylinder is rotatably connected to the outer surface of the bottom of the sealed barrel, and the bottom of the outer cylinder is in contact with the bottom of the inner cylinder.

[0040] The inner hole is provided in multiple parts, all of which are opened at the bottom of the inner cylinder;

[0041] The outer hole is provided in multiple ways and is opened at the bottom of the outer cylinder. The center of the outer hole and the center of the inner hole are on the same circumference.

[0042] The discharge pipe is sleeved outside the outer cylinder and rotatably connected to the outer cylinder.

[0043] When the fertigation solution in the sealed container needs to be transported to the field through the pipeline network, the controller first opens the solenoid valve in the inner cylinder. Then, the fertigation solution in the sealed container flows downward into the inner cylinder. Next, the operator rotates the outer cylinder to adjust the overlap between the outer hole on the outer cylinder and the inner hole on the inner cylinder, thereby adjusting the flow area of ​​the channel and thus the flow rate of the fertigation solution. When the overlap between the outer hole and the inner hole on the inner cylinder is high, the flow rate of the fertigation solution is high; when the overlap between the outer hole and the inner hole on the inner cylinder is low, the flow rate of the fertigation solution is low.

[0044] Preferably, a filter screen is fixedly installed in both the inner and outer holes.

[0045] By fixing filter screens in both the inner and outer holes, the mixed liquid can be filtered when it is discharged, reducing the possibility of pipe network blockage later.

[0046] Preferably, a pressure regulating valve is installed inside the discharge pipe. The pressure regulating valve is controlled by a controller, which allows the operator to easily adjust the discharge pressure of the discharge pipe and improves the practicality of the water-fertilizer synthesis equipment.

[0047] The beneficial effects of this invention are as follows:

[0048] 1. The present invention provides a sealed water-fertilizer synthesis device with pressure regulation. By setting up a grinding unit and using water flow as power to drive the grinding unit, the device effectively utilizes water energy and saves resources. When the grinding unit is working, it grinds block or granular fertilizer into powder. At the same time, during the grinding of fertilizer, the water flow washes and mixes the fertilizer, so that the fertilizer can be initially mixed with the water flow during the grinding process, thereby improving the mixing effect.

[0049] 2. The present invention provides a sealed water-fertilizer synthesis device with pressure regulation. By setting up a stirring detection unit, when the fertilizer and water source are stirred, the concentration of the mixture at different levels in the sealed tank can be detected by utilizing the changes in the state of the stirring element under different resistances. Feedback is provided through the display screen on the sealed tank, and water or fertilizer is added in time to ensure that the concentration of the water-fertilizer mixture in the sealed tank reaches the specified value, thereby ensuring the fertilization effect on plants and improving the practicality of the water-fertilizer synthesis device.

[0050] Simultaneously, the grinding unit grinds the fertilizer and the stirring element mixes the fertilizer with water, further homogenizing the concentration of the mixture in the sealed tank and improving the irrigation effect.

[0051] 3. The present invention provides a sealed water-fertilizer synthesis device with pressure regulation. By setting a flow regulation unit, the operator can adjust the overlap between the outer hole on the outer cylinder and the inner hole on the inner cylinder by rotating the outer cylinder, thereby adjusting the flow area of ​​the channel and thus adjusting the flow rate of the water-fertilizer mixture. When the overlap between the outer hole and the inner hole on the inner cylinder is high, the flow rate of the water-fertilizer mixture is large; when the overlap between the outer hole and the inner hole on the inner cylinder is low, the flow rate of the water-fertilizer mixture is small.

[0052] 4. The present invention provides a sealed water-fertilizer synthesis device with pressure regulation. By setting up filter screens fixedly installed in both the inner and outer holes, the water-fertilizer mixture can be filtered when discharged, reducing the possibility of subsequent pipeline blockage.

[0053] 5. The present invention provides a sealed water and fertilizer synthesis device with pressure regulation. By installing a pressure regulating valve inside the discharge pipe, the operator can easily adjust the discharge pressure of the discharge pipe, thereby improving the practicality of the water and fertilizer synthesis device.

[0054] 6. The present invention provides a sealed water-fertilizer synthesis device with pressure regulation. By setting a connecting frame, a conical disk and a centrifuge hole, the rotation of the second rotating shaft drives the conical disk to rotate. When the conical disk rotates, it generates centrifugal force on the water-fertilizer mixture located in the cavity formed by the connecting frame and the conical disk, causing part of the mixture to be thrown out to the surroundings through the centrifuge hole and then sprinkled downward into the sealed barrel, which further improves the water-fertilizer mixing effect.

[0064] 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.

[0065] like Figure 1 and Figure 2 As shown, the present invention provides a sealed water-fertilizer synthesis device with pressure regulation, which includes: a sealed tank 1, a diversion tank 2, a water inlet pipe 3, an impeller 4, a grinding unit 5, a stirring and detection unit 6, and a motor 13.

[0066] The sealed barrel 1 is a cylindrical barrel structure with both ends closed;

[0067] The drainage bucket 2 is fixedly installed on the upper surface of the sealing bucket 1;

[0068] The water inlet pipe 3 passes through one side of the diversion bucket 2, and the water inlet pipe 3 is fixedly connected to the diversion bucket 2;

[0069] The impeller 4 is located inside the diversion bucket 2, and the water inlet pipe 3 is positioned towards the blades of the impeller 4.

[0070] The grinding unit 5 is installed on the top of the sealed barrel 1, and the grinding unit 5 is used to grind the block fertilizer that is not easily soluble in water into powder.

[0071] The stirring detection unit 6 is installed inside the sealed barrel 1 and located below the grinding unit 5. The stirring detection unit 6 is used to detect the concentration of the mixture while stirring the water-fertilizer mixture.

[0072] Motor 13 is fixedly installed on the inner wall of the diversion tank 2, and the motor 13 is used to provide power to the stirring detection unit 6;

[0073] By adopting the above technical solution, when mixing water and fertilizer, some organic fertilizer particles are large and not easily soluble in water, which can easily cause uneven mixing of fertilizer and water. Therefore, when adding water and fertilizer, water is first pumped into the inlet tank 2 through the inlet pipe 3. Since the inlet pipe 3 is set towards the blades of the impeller 4, the water flows into the inlet tank 2 through the inlet pipe 3 and drives the impeller 4 to rotate. When the impeller 4 rotates, it drives the grinding unit 5 to work. The grinding unit 5 grinds the lumpy fertilizer into powder and it falls down. At the same time, the water flows and mixes it, so that the fertilizer can be initially mixed with the water flow during grinding, thus improving the mixing effect.

[0074] After the fertilizer and water flow into the sealed container 1, they are stirred by the stirring and detection unit 6. If the concentration of the mixture formed by the fertilizer and water in the sealed container 1 is uneven, multiple layers of mixture with different concentrations will appear in the sealed container 1. At this time, the stirring element in the stirring and detection unit 6 will encounter greater resistance when stirring in the high-concentration layer of mixture, and less resistance when stirring in the low-concentration layer of mixture. Therefore, the concentration of the mixture at different levels in the sealed container 1 is monitored by the state change of the stirring element detected by the detector. Based on the feedback data, water or fertilizer is added in time to ensure that the concentration of the water-fertilizer mixture in the sealed container 1 reaches the specified value, thus ensuring the fertilization effect on the plants and improving the practicality of the water-fertilizer synthesis equipment.

[0075] Compared to existing technologies where some lumpy fertilizers are difficult to dissolve in water during the mixing of water and fertilizer, leading to uneven concentration of the water-fertilizer mixture and ineffective fertilizer utilization, thus reducing the fertilization effect on crops, this invention, by incorporating a grinding unit 5 and utilizing water flow as a power source to drive the grinding unit 5, effectively utilizes water energy and saves resources. During operation, the grinding unit 5 grinds lumpy or granular fertilizers into powder. Simultaneously, the water flow washes and mixes the fertilizer during grinding, ensuring initial mixing with the water flow and improving the mixing effect. Furthermore, the invention incorporates a stirring mechanism... The detection unit 6, when mixing fertilizer and water, utilizes the changes in resistance experienced by the stirring element to detect the concentration of the mixture at different levels within the sealed container 1. Feedback is then provided via a display screen on the sealed container 1, allowing for timely addition of water or fertilizer to ensure the water-fertilizer mixture concentration in the sealed container 1 reaches the specified value. This guarantees the fertilization effect on plants and improves the practicality of the water-fertilizer synthesis equipment. Simultaneously, in conjunction with the grinding unit 5, the fertilizer is ground, and the mixing element further agitates the fertilizer and water, uniformly distributing the mixture concentration within the sealed container 1 and enhancing irrigation efficiency.

[0076] like Figures 1 to 5As shown, in a specific embodiment of the present invention, the grinding unit 5 includes: a first rotating shaft 51, an upper grinding disc 52, a lower grinding disc 53, and a discharge hole 54.

[0077] The first rotating shaft 51 passes through the center of the impeller 4 and is fixedly connected to the impeller 4. The first rotating shaft 51 passes downward through the upper surface of the sealing barrel 1. The first rotating shaft 51 is rotatably connected to the sealing barrel 1. The motor 13 is located above the first rotating shaft 51. The output shaft of the motor 13 is fixedly connected to the first rotating shaft 51.

[0078] The upper grinding disc 52 is located below the impeller 4. The upper grinding disc 52 is located on the first rotating shaft 51. The upper grinding disc 52 is fixedly connected to the first rotating shaft 51. The end of the upper grinding disc 52 away from the impeller 4 is set as a conical structure. The upper grinding disc 52 is rotatably connected to the diversion bucket 2 through a bracket.

[0079] The lower grinding disc 53 is located below the upper grinding disc 52. The lower grinding disc 53 is fixedly connected to the sealing barrel 1. A tapered groove is provided on one end face of the lower grinding disc 53 near the upper grinding disc 52. There is a gap between the upper grinding disc 52 and the lower grinding disc 53.

[0080] The discharge hole 54 is located on the end face of the lower grinding disc 53 away from the upper grinding disc 52;

[0081] A connecting frame 7 is fixedly connected to one end face of the lower grinding disc 53 away from the upper grinding disc 52. The connecting frame 7 is fixedly connected to the sealing barrel 1 through an annular frame. A conical disc 8 is provided inside the connecting frame 7. The conical disc 8 is rotatably connected to the connecting frame 7. The tip of the conical disc 8 faces the upper grinding disc 52. A plurality of centrifugal holes 71 are opened at the bottom end of the connecting frame 7.

[0082] The stirring detection unit 6 includes: a second rotating shaft 62, a mounting ring 63, a stirring rod 64, and an angle sensor 65;

[0083] The second rotating shaft 62 passes through the discharge hole 54 and is located below the upper grinding disc 52. The second rotating shaft 62 is fixedly connected to the upper grinding disc 52, and the conical disc 8 is fixedly installed on the second rotating shaft 62.

[0084] Multiple mounting rings 63 are provided, and the multiple mounting rings 63 are axially and sequentially sleeved on the second rotating shaft 62, and the multiple mounting rings 63 are rotatably connected to the second rotating shaft 62;

[0085] The stirring rods 64 are provided in multiple and staggered arrangement on both sides of the second rotating shaft 62, and the stirring rods 64 are fixedly connected to the mounting ring 63;

[0086] The angle sensor 65 is located between the conical disk 8 and the stirring rod 64, and the angle sensor 65 is fixedly connected to the conical disk 8.

[0087] By adopting the above technical solution, when mixing water and fertilizer, some organic fertilizer particles are large and not easily soluble in water, which can easily cause uneven mixing of fertilizer and water. Therefore, when adding water and fertilizer, water is first pumped into the inlet tank 2 through the inlet pipe 3. Since the inlet pipe 3 is oriented towards the impeller 4 blades, the water flowing into the inlet tank 2 through the inlet pipe 3 drives the impeller 4 to rotate. When the impeller 4 rotates, it drives the upper grinding disc 52 to rotate through the first rotating shaft 51. At the same time, the operator adds fertilizer into the gap between the upper grinding disc 52 and the lower grinding disc 53. The upper grinding disc 52 rotates while the lower grinding disc 53 remains stationary. Therefore, when the upper grinding disc 52 rotates, it grinds the fertilizer in the gap into smaller particles or powder. At the same time, water continuously enters the diversion tank 2 from the water inlet pipe 3 and flows downward through the gap between the upper grinding disc 52 and the lower grinding disc 53. Therefore, after the fertilizer is ground, it is mixed with the water flow. After the fertilizer and water are initially mixed, the mixture falls through the discharge hole 54 into the cavity formed by the connecting frame 7 and the conical disc 8. The initially mixed water-fertilizer mixture enters the connecting frame 7 and then flows out through the centrifugal hole 71 opened on it, and then enters the sealed tank 1.

[0088] When the upper grinding disc 52 rotates, it drives the second rotating shaft 62 to rotate. The rotation of the second rotating shaft 62 drives the conical disc 8 to rotate. When the conical disc 8 rotates, it generates centrifugal force on the water-fertilizer mixture in the cavity formed by the connecting frame 7 and the conical disc 8, causing part of the mixture to be thrown out to the surroundings through the centrifugal hole 71 and then sprinkled downwards into the sealed bucket 1, which further improves the water-fertilizer mixing effect.

[0089] When the fertilizer and water flow into the sealed tank 1, the controller controls the motor 13 to start. The output shaft of the motor 13 rotates, which drives the first rotating shaft 51 to rotate. The rotation of the first rotating shaft 51 drives the upper grinding disc 52 to rotate. The rotation of the upper grinding disc 52 drives the second rotating shaft 62 to rotate. Since the mounting ring 63 is rotatably connected to the second rotating shaft 62, and the stirring rod 64 installed on the second mounting ring 63 does not contact the inner wall of the sealed tank 1, there is a gap between the two. Therefore, the stirring rod 64 is not restricted at this time and will follow the second rotating shaft 62 to rotate under the action of friction and torque. If the concentration of the mixture formed by the fertilizer and water in the sealed tank 1 is uneven at this time, then there will be multiple layers of mixture with different concentrations in the sealed tank 1. This is because multiple stirring rods 64 are arranged in multiple layers and staggered on both sides of the second rotating shaft 62.

[0090] Therefore, when the stirring rod 64 is stirring in the high-concentration water-fertilizer mixture, it experiences greater resistance. The resistance of the stirring rod 64 offsets most of the friction and torque generated by the second rotating shaft 62. At this time, there is a large speed difference between the stirring rod 64 and the second rotating shaft, and the speed of the stirring rod 64 is lower than that of the second rotating shaft 62.

[0091] If the resistance encountered by the stirring rod 64 and the friction and torque generated by the second rotating shaft 62 are at the standard value when the stirring rod 64 is stirring in the water-fertilizer mixture with a concentration layer that meets the standard, the stirring rod 64 will rotate synchronously with the second rotating shaft, and the angle change value of the stirring rod 64 at this time is the standard value.

[0092] When stirring rod 64 is stirring in the low-concentration layer of the water-fertilizer mixture, it experiences less resistance compared to the high-concentration layer. The resistance of the less-resisted stirring rod 64 offsets a smaller portion of the friction and torque generated by the second rotating shaft 62. At this point, there is a small speed difference between the less-resisted stirring rod 64 and the second rotating shaft; that is, the speed of the less-resisted stirring rod 64 is faster than that of the more-resisted stirring rod 64. Consequently, the angle change values ​​of both the stirring rod 64 in the higher and lower concentration layers are greater than the standard values, and the angle change value of the stirring rod 64 in the higher concentration layer is greater than that in the lower concentration layer. At this time, the angle sensor 65 feeds back the angle change signals of the stirring rods 64 in different layers, which are then displayed on the screen on the sealed container 1. Water or fertilizer is added promptly to ensure that the concentration of the water-fertilizer mixture in the sealed container 1 reaches the specified value, guaranteeing the fertilization effect on the plants and improving the practicality of the water-fertilizer synthesis equipment.

[0093] Simultaneously, the grinding unit 5 grinds the fertilizer and the stirring rod 64 mixes the fertilizer with water to further homogenize the concentration of the mixed solution in the sealed tank 1 and improve the irrigation effect.

[0094] like Figure 1 and Figure 3 As shown, in a specific embodiment of the present invention, a scraper 10 is fixedly connected to one end of the stirring rod 64 away from the mounting ring 63, and the scraper 10 is in contact with the inner wall of the sealing barrel 1 at the other end away from the stirring rod 64. The scraper 10 is made of an elastic material.

[0095] By adopting the above technical solution, when the stirring rod 64 rotates, it drives the scraper 10 to rotate. When the scraper 10 rotates, it scrapes against the inner wall of the sealed bucket 1, thereby scraping off some of the fertilizer adhering to the inner wall of the sealed bucket 1 and improving the uniformity of water-fertilizer mixing.

[0096] Meanwhile, the scraper 10 is made of elastic material to prevent the stirring rod 64 from being restricted by the scraper 10 when it rotates, and to prevent the scraper 10 from generating large rotational resistance on the stirring rod 64, which would affect the concentration detection effect of the water-fertilizer mixture.

[0097] like Figure 2 and Figure 3As shown, in a specific embodiment of the present invention, a feed pipe 11 is passed through the diversion bucket 2, and one end of the feed pipe 11 is located inside the diversion bucket 2 above the gap between the upper grinding disc 52 and the lower grinding disc 53.

[0098] By adopting the above technical solution, it is convenient for workers to add fertilizer through the gap between the upper grinding disc 52 and the lower grinding disc 53 via the feed pipe 11.

[0099] like Figure 1 , Figure 6 and Figure 7 As shown, in a specific embodiment of the present invention, the sealed water and fertilizer synthesis device with pressure regulation further includes: a flow regulation unit 12;

[0100] The flow regulating unit 12 is located at the bottom of the sealed container 1, and the flow regulating unit 12 is used to regulate the discharge volume of the mixture;

[0101] The flow regulating unit 12 includes: an inner cylinder 121, an outer cylinder 122, an inner hole 123, an outer hole 124, and a discharge pipe 125;

[0102] The inner cylinder 121 is a barrel-shaped structure with an opening at one end and a closed end. The inner cylinder 121 is fixed to the bottom of the sealed barrel 1. The inner cylinder 121 is fixed to the sealed barrel 1 and is connected to the sealed barrel 1.

[0103] The outer cylinder 122 is a barrel-shaped structure with an opening at one end and a closed end. The outer cylinder 122 is sleeved on the outside of the inner cylinder 121. The upper end of the outer cylinder 122 is rotatably connected to the bottom outer surface of the sealed barrel 1, and the bottom of the outer cylinder 122 is in contact with the bottom of the inner cylinder 121.

[0104] The inner hole 123 is provided in multiple ways and is opened at the bottom of the inner cylinder 121;

[0105] The outer hole 124 is provided in multiple ways and is opened at the bottom of the outer cylinder 122. The center of the outer hole 124 and the center of the inner hole 123 are on the same circumference.

[0106] The discharge pipe 125 is sleeved on the outside of the outer cylinder 122 and is rotatably connected to the outer cylinder 122;

[0107] By adopting the above technical solution, when the water-fertilizer mixture in the sealed container 1 needs to be transported to the field through the pipeline network, the solenoid valve in the inner cylinder 121 is first opened by the controller. Then, the water-fertilizer mixture in the sealed container 1 flows downward into the inner cylinder 121. Then, the operator rotates the outer cylinder 122 to adjust the overlap between the outer hole 124 on the outer cylinder 122 and the inner hole 123 on the inner cylinder 121, thereby adjusting the flow area of ​​the channel and thus adjusting the flow rate of the water-fertilizer mixture. When the overlap between the outer hole 124 and the inner hole 123 on the inner cylinder 121 is high, the flow rate of the water-fertilizer mixture is large; when the overlap between the outer hole 124 and the inner hole 123 on the inner cylinder 121 is low, the flow rate of the water-fertilizer mixture is small.

[0108] In one specific embodiment of the present invention, filter screens are fixedly installed in both the inner hole 123 and the outer hole 124;

[0109] By adopting the above technical solution, and by fixing filter screens in both the inner hole 123 and the outer hole 124, the mixed liquid can be filtered when it is discharged, reducing the possibility of subsequent pipe network blockage.

[0110] As a specific embodiment of the present invention, a pressure regulating valve is installed inside the discharge pipe 125;

[0111] By adopting the above technical solution, the pressure regulating valve is controlled by the controller, which makes it easy for the staff to adjust the discharge pressure of the discharge pipe 125 and improves the practicality of the water and fertilizer synthesis equipment.

[0112] Working principle:

[0113] When mixing water and fertilizer, some organic fertilizer particles are large and not easily soluble in water, which can easily lead to uneven mixing. Therefore, when adding water and fertilizer, water is first pumped into the inlet tank 2 through the inlet pipe 3. Since the inlet pipe 3 is oriented towards the impeller 4 blades, the water flowing into the inlet tank 2 through the inlet pipe 3 drives the impeller 4 to rotate. When the impeller 4 rotates, it drives the upper grinding disc 52 to rotate through the first rotating shaft 51. At the same time, the operator adds fertilizer into the gap between the upper grinding disc 52 and the lower grinding disc 53. The upper grinding disc 52 rotates while the lower grinding disc 53 remains stationary. Therefore, when the upper grinding disc 52 rotates, it grinds the fertilizer in the gap into smaller particles or powder. At the same time, water continuously enters the diversion tank 2 from the water inlet pipe 3 and flows downward through the gap between the upper grinding disc 52 and the lower grinding disc 53. Therefore, after the fertilizer is ground, it is mixed with the water flow. After the fertilizer and water are initially mixed, the mixture falls through the discharge hole 54 into the cavity formed by the connecting frame 7 and the conical disc 8. The initially mixed water-fertilizer mixture should flow out through the centrifuge hole 71 opened at the connecting frame 7 and enter the sealed tank 1.

[0114] When the upper grinding disc 52 rotates, it drives the second rotating shaft 62 to rotate. The rotation of the second rotating shaft 62 drives the conical disc 8 to rotate. When the conical disc 8 rotates, it generates centrifugal force on the water-fertilizer mixture in the cavity formed by the connecting frame 7 and the conical disc 8, causing part of the mixture to be thrown out to the surroundings through the centrifugal hole 71 and then sprinkled downwards into the sealed bucket 1, which further improves the water-fertilizer mixing effect.

[0115] When the fertilizer and water flow into the sealed tank 1, the controller controls the motor 13 to start. The output shaft of the motor 13 rotates, which drives the first rotating shaft 51 to rotate. The rotation of the first rotating shaft 51 drives the upper grinding disc 52 to rotate. The rotation of the upper grinding disc 52 drives the second rotating shaft 62 to rotate. Since the mounting ring 63 is rotatably connected to the second rotating shaft 62, and the stirring rod 64 installed on the second mounting ring 63 does not contact the inner wall of the sealed tank 1, there is a gap between the two. Therefore, the stirring rod 64 is not restricted at this time and will follow the second rotating shaft 62 to rotate under the action of friction and torque. If the concentration of the mixture formed by the fertilizer and water in the sealed tank 1 is uneven at this time, then there will be multiple layers of mixture with different concentrations in the sealed tank 1. This is because multiple stirring rods 64 are arranged in multiple layers and staggered on both sides of the second rotating shaft 62.

[0116] Therefore, when the stirring rod 64 is stirring in the high-concentration water-fertilizer mixture, it experiences greater resistance. The resistance of the stirring rod 64 offsets most of the friction and torque generated by the second rotating shaft 62. At this time, there is a large speed difference between the stirring rod 64 and the second rotating shaft, and the speed of the stirring rod 64 is lower than that of the second rotating shaft 62.

[0117] If the resistance encountered by the stirring rod 64 and the friction and torque generated by the second rotating shaft 62 are at the standard value when the stirring rod 64 is stirring in the water-fertilizer mixture with a concentration layer that meets the standard, the stirring rod 64 will rotate synchronously with the second rotating shaft, and the angle change value of the stirring rod 64 at this time is the standard value.

[0118] When stirring rod 64 is stirring in the low-concentration layer of the water-fertilizer mixture, it experiences less resistance compared to the high-concentration layer. The resistance of the less-resisted stirring rod 64 offsets a smaller portion of the friction and torque generated by the second rotating shaft 62. At this point, there is a small speed difference between the less-resisted stirring rod 64 and the second rotating shaft; that is, the speed of the less-resisted stirring rod 64 is faster than that of the more-resisted stirring rod 64. Consequently, the angle change values ​​of both the stirring rod 64 in the higher and lower concentration layers are greater than the standard values, and the angle change value of the stirring rod 64 in the higher concentration layer is greater than that in the lower concentration layer. At this time, the angle sensor 65 feeds back the angle change signals of the stirring rods 64 in different layers, which are then displayed on the screen on the sealed container 1. Water or fertilizer is added promptly to ensure that the concentration of the water-fertilizer mixture in the sealed container 1 reaches the specified value, guaranteeing the fertilization effect on the plants and improving the practicality of the water-fertilizer synthesis equipment.

[0119] Workers can adjust the flow area of ​​the channel by rotating the outer cylinder 122 to adjust the overlap between the outer hole 124 on the outer cylinder 122 and the inner hole 123 on the inner cylinder 121, thereby adjusting the flow rate of the water-fertilizer mixture. When the overlap between the outer hole 124 and the inner hole 123 on the inner cylinder 121 is high, the flow rate of the water-fertilizer mixture is large; when the overlap between the outer hole 124 and the inner hole 123 on the inner cylinder 121 is low, the flow rate of the water-fertilizer mixture is small.
