Description

Technical Field

[0001] The present invention relates to the technical field of agricultural irrigation and fertilization, in particular to adjustable precision fertilization and irrigation equipment. Background Art

[0002] Water and fertilizer are two important factors affecting crop growth. Exploring technologies and methods to increase crop productivity through fertilization and irrigation has long been a hot topic in agricultural research. Fertilization often involves dissolving granular fertilizer in water to form liquid fertilizer, which is then applied to farmland using fertigation devices. Compared to traditional methods of directly spreading granular fertilizer on farmland, fertigation reduces fertilizer volatilization and loss, improving fertilizer utilization. Traditional fertilization methods can cause fertilizer to run off with rainwater, polluting soil and water. Fertigation, on the other hand, allows for more precise control of fertilizer application, reducing negative environmental impacts. Fertigation often involves dissolving granular fertilizer before application, but this method suffers from the common problem of imprecise fertilizer ratio control.

[0003] Authorization announcement number: CN118556486B discloses a precision fertilization device for crops. This device integrates a dispensing tank, a water storage tank, a dispensing mechanism, and a water metering assembly to achieve a quantitative ratio of granular fertilizer to clean water. Its core technologies include: utilizing spiral lifting blades to transport fertilizer granules to a dispensing chamber. The synergistic effect of a curved dispensing plate and a limited pusher assembly allows for precise control of the single dispensing volume. Furthermore, the piston mechanism in the water dispensing cylinder provides a quantitative water supply, ensuring a stable liquid fertilizer ratio and effectively avoiding fertilizer waste and seedling burn associated with traditional devices.

[0004] However, the device still has significant limitations in practical applications. First, when multiple compound fertilizers need to be applied, the user needs to mix the different fertilizers evenly in advance through external equipment, and then put them into the fertilizer chamber. This process increases the number of operating steps and reduces the efficiency of field operations, especially in scenarios where frequent adjustments to the formula are required. It is more cumbersome. Secondly, although the device can quantitatively adjust a single fertilizer, it lacks the function of independent measurement and dynamic proportioning of multiple fertilizers. At the same time, the storage trough design on the partition seat is only suitable for the temporary storage of a single granular fertilizer, and cannot achieve partitioned storage of multiple fertilizers and precise on-demand dispensing.

[0005] Based on this, adjustable precision fertilization and irrigation equipment is now available, which can eliminate the disadvantages of existing devices. Summary of the Invention

A discharge pipe 41 is symmetrically connected to one end of the delivery pipe 40. A connecting frame is fixed at the other end of the delivery pipe 40. The connecting frame is rotatably mounted on the first mounting shaft 25. A spiral plate 42 is fixed at a position corresponding to the internal position of the delivery pipe 40 on the first mounting shaft 25. The spiral plate 42 is tightly attached to the inside of the delivery pipe 40. Several mixing plates are provided on the outside of the delivery pipe 40. A first mixing frame is symmetrically arranged at one end of the first mounting shaft 25. The other end of the first mixing frame is rotatably mounted on the first sleeve shaft 26. When in use, When the first installation shaft 25 and the first sleeve shaft 26 rotate, the first installation shaft 25 drives the first mixing rack and the spiral plate 42 to rotate, and the first sleeve shaft 26 drives the conveying pipe 40 to rotate, and the first installation shaft 25 and the first sleeve shaft 26 rotate in opposite directions, so that the conveying pipe 40 mixes the liquid and granular fertilizer inside the mixing chamber through the mixing plate.

The third motor 50 is fixedly arranged at the upper end of the liquid storage tank 12. When in use, after the liquid fertilizer inside the mixing chamber is transported to the inside of the liquid storage tank 12, the external control component controls the third motor 50 to start, and the third motor 50 drives the sixth bevel gear and the seventh bevel gear to rotate through the eighth bevel gear, so that the second mounting shaft 48 and the second sleeve shaft 49 rotate simultaneously, and the rotation directions are opposite. The second mounting shaft 48 mixes the liquid fertilizer inside the liquid storage tank 12 through several second mixing racks, and the second sleeve shaft 49 mixes it through the mixing plate to prevent the liquid fertilizer inside the liquid storage tank 12 from precipitating. Example 2

[0036] The difference from Example 1 is that one end of the liquid inlet pipe is connected to a filter pipe 34, the filter pipe 34 is fixed to the outside of the batching tank 11, a filter screen plate 35 is fixed inside the filter pipe 34, and a cleaning rod is tightly attached to one side of the filter screen plate 35. The cleaning rod is fixed to one end of the transmission shaft, and a sealing plate is rotatably provided on the transmission shaft. The sealing plate is fixed inside the filter pipe 34, and an impeller 36 is fixed to the other end of the transmission shaft. A connecting pipe is provided on the filter pipe 34 at a position corresponding to the position of the impeller 36, and a discharge joint is provided on the filter pipe 34 at a position between the filter screen plate 35 and the sealing plate. The discharge joint is threadedly connected with a collecting bottle 37. When in use, the connecting pipe is connected to the output end of the external liquid supply component. When the external liquid supply component transports liquid to the inside of the filter tube 34, the impact of the liquid drives the impeller 36 to rotate. When the liquid flows through the upper end of the sealing plate, the liquid enters the middle of the filter tube 34, and then enters the liquid inlet pipe after being filtered by the filter screen plate 35. When the impeller 36 rotates, it drives the cleaning rod to rotate through the transmission shaft. The cleaning rod is in close contact with one side of the filter screen plate 35, thereby cleaning the impurities attached to one side of the filter screen plate 35. The impurities are precipitated into the collecting bottle 37 and then collected.

[0037] A branch pipe is provided on the filter tube 34 at a position corresponding to one side of the filter screen plate 35, and the other end of the branch pipe is communicated with the interior of the auxiliary tank 44.

One end of the liquid adding pipe extends into the mixing chamber, and a solenoid valve 45 is connected to the liquid adding pipe. A conductivity sensor 43 is installed at the bottom of the mixing chamber. The conductivity sensor 43 and the solenoid valve 45 are both electrically connected to a control component 46, and the control component 46 is fixedly mounted on the upper end of the liquid storage tank 12. When in use, when the external liquid supply component adds liquid to the interior of the mixing chamber through the liquid adding pipe, part of the liquid enters the auxiliary tank 44 through the branch pipe. Since the solenoid valve 45 closes one end of the liquid adding pipe, the auxiliary tank After the interior of 44 is filled with liquid, no more liquid enters. When the valve 38 is closed, the output end of the external liquid supply component is closed, and the liquid inside the auxiliary tank 44 does not flow back. Then, after the mixing mechanism mixes for a certain period of time, the control component 46 starts the conductivity sensor 43 to detect the concentration of liquid fertilizer inside the mixing chamber. The conductivity sensor 43 reflects its concentration by measuring the conductivity of the liquid fertilizer, and then transmits the detection data to the interior of the control component 46. When the concentration of liquid fertilizer inside the mixing chamber is high, the control component 46 controls the solenoid valve 45 to start, so that the liquid inside the auxiliary tank 44 is quantitatively added into the mixing chamber. It is worth noting that the conductivity sensor 43 and the control component 46 are both existing components, and the specific structure and working principle are well known, so they will not be described here.

[0038] The above embodiment discloses an adjustable precision fertilization and irrigation equipment, in which, when it is necessary to fertilize and irrigate crops, the feed tank 11 and the liquid storage tank 12 are moved to the work site through the frame 13, and the irrigation pipe is connected to the liquid outlet joint 53, and the connecting pipe is connected to the output end of the external liquid supply component, and different types of granular fertilizers are stored in different storage boxes 14 respectively. According to the usage ratio of different granular fertilizers, the corresponding first electric push rod 22 is controlled by the external control component, and the output end of the first electric push rod 22 drives the sliding rod 21 to slide through the rotating plate, and the sliding rod 21 drives the adjusting plate 19 to slide in the distribution trough through the connecting rod 20, thereby adjusting the capacity of the distribution trough, and then starting the first motor 24 to make several distribution troughs. The rollers 18 rotate simultaneously, and the dividing roller 18 adds granular fertilizer to the inside of the premixing box 16 in a quantitative manner through several dividing troughs. The dividing roller 18 stops after rotating a fixed number of circles, and the quantitative addition is completed. Then the second motor 29 is started, and the output end of the second motor 29 is engaged with the third bevel gear and the fourth bevel gear through the fifth bevel gear, so that the first mounting shaft 25 and the first sleeve shaft 26 rotate simultaneously, and the rotation directions are opposite. The first mounting shaft 25 drives the first bevel gear 28 to rotate, and the first bevel gear 28 is respectively engaged with several second bevel gears. At the same time, the first sleeve shaft 26 drives several mixing rods 27 to revolve through the fixed tube, so that the mixing rod 27 can revolve and rotate, thereby mixing the granular fertilizer inside the premixing box 16.

[0039] Then the external control component controls the second electric push rod 32 to start, and the output end of the second electric push rod 32 drives the two baffle plates 31 to slide, and the baffle plate 31 drives the rack 39 to move through the second fixed rod, and the rack 39 is engaged with the gear, so that the valve 38 is opened, and the granular fertilizer mixed in the premixing box 16 falls to the upper end of the dividing plate 33, and the dividing plate 33 makes the granular fertilizer spread. At the same time, the output end of the external liquid supply component transports liquid to the inside of the mixing chamber through the liquid inlet pipe. After the second electric push rod 32 works for a certain period of time, the granular fertilizer in the premixing box 16 is discharged, and the external liquid supply component adds a certain amount of liquid to the inside of the mixing chamber. Then the output end of the second electric push rod 32 drives the The dynamic baffle plate 31 returns to its initial position, so that the discharge end of the premixing box 16 is closed, the valve 38 is closed, the first installation shaft 25 drives the first mixing rack and the spiral plate 42 to rotate, and the first sleeve shaft 26 drives the conveying pipe 40 to rotate, and the first installation shaft 25 and the first sleeve shaft 26 rotate in opposite directions, so that the conveying pipe 40 mixes the liquid and granular fertilizer inside the mixing chamber through the mixing plate, and the first installation shaft 25 mixes through the first mixing rack, and at the same time, the spiral plate 42 cooperates with the conveying pipe 40 to convey the liquid and granular fertilizer at the bottom end of the mixing chamber to the end of the conveying pipe 40, and then discharges them through the drain pipe 41, so that the liquid and granular fertilizer inside the mixing chamber circulate.

[0040] After the mixing mechanism has been mixing for a certain period of time, the control component 46 starts the conductivity sensor 43 to detect the concentration of the liquid fertilizer in the mixing chamber. The conductivity sensor 43 reflects the concentration by measuring the conductivity of the liquid fertilizer, and then transmits the detection data to the inside of the control component 46. When the concentration of the liquid fertilizer in the mixing chamber is high, the control component 46 controls the solenoid valve 45 to start, so that the liquid in the auxiliary tank 44 is quantitatively added to the mixing chamber. After the liquid fertilizer is mixed, the first liquid pump 47 extracts the liquid fertilizer in the mixing chamber into the liquid storage tank 12. The external control component controls the third motor 50 to start, and the third motor 50 is turned on. The machine 50 drives the sixth bevel gear and the seventh bevel gear to rotate through the eighth bevel gear, so that the second installation shaft 48 and the second sleeve shaft 49 rotate simultaneously, and the rotation directions are opposite. The second installation shaft 48 mixes the liquid fertilizer inside the liquid storage tank 12 through several second mixing racks, and the second sleeve shaft 49 mixes through the mixing plate to prevent the liquid fertilizer inside the liquid storage tank 12 from precipitating. The second liquid pump 51 extracts the liquid fertilizer inside the liquid storage tank 12 into the liquid distribution pipe 52, and the external irrigation pipe is connected to one end of the liquid outlet joint 53, so that the liquid distribution pipe 52 diverts the liquid fertilizer to the inside of several irrigation pipes through several liquid outlet joints 53.
