Description

Technical Field

[0001] This utility model relates to the field of fertilizer diversion technology, specifically a diverter structure for precision fertilization in an integrated water and fertilizer machine. Background Technology

[0002] In the process of agricultural modernization, fertigation technology has become a key technology for facility agriculture, field planting and other scenarios due to its core advantages of saving water and fertilizer and improving crop yield and quality. The core logic of this technology is to dissolve fertilizer in irrigation water and deliver it to the roots or leaves of crops through a pipeline system to achieve simultaneous water and fertilizer supply. As the core component of the fertigation system, the performance of the distributor directly determines the uniformity of water and fertilizer mixing, the stability of delivery and the accuracy of fertilization, and is a key link to ensure the efficient operation of the entire system.

[0003] Currently, the split-flow structure of mainstream integrated water and fertilizer machines on the market still has many technical pain points in practical applications, making it difficult to meet the needs of modern agriculture for precision fertilization. Specific problems are as follows:

[0004] Most existing water and fertilizer distribution devices are not equipped with efficient and targeted stirring mechanisms, or only use a simple single-shaft stirring design, which lacks effective stirring of the bottom area of ​​the container. Some fertilizer particles are easy to settle at the bottom of the storage tank, forming clumps that are difficult to dissolve. When these clumps enter the delivery pipeline along with the water and fertilizer, they will not only block the nozzles or pipelines, but also cause a sudden increase in the concentration in the local fertilization area, causing root and leaf burn to crops.

[0005] Existing devices often lack effective pressure stabilizing components or only use simple valve throttling methods to control pressure. During system operation, factors such as changes in irrigation water pressure and fluctuations in fertilizer injection can cause drastic changes in the inlet pressure of the distributor. These pressure fluctuations are directly transmitted to each distributor channel, causing a sudden increase in flow in some channels and a sudden decrease in flow in others, making it impossible to guarantee a stable supply of water and fertilizer to each delivery pipeline.

[0006] Therefore, it is necessary to design a diverter structure for precision fertilization in an integrated water and fertilizer machine to solve the above problems. Utility Model Content

[0009] The diversion mechanism includes a liquid storage tank, which is fixedly connected to the top of the base. A fixing frame is fixedly connected to the top periphery of the liquid storage tank. A hydraulic cylinder is fixedly connected to the top of the fixing frame. A sealing cover is fixedly connected to the bottom of the hydraulic cylinder. The sealing cover is located on the top of the liquid storage tank. A liquid delivery pipe is fixedly connected to the bottom front side of the liquid storage tank. A water pump is fixedly connected to the periphery of the liquid delivery pipe. A pressure stabilizing valve is fixedly connected to the front side of the liquid delivery pipe. A diverter body is fixedly connected to the front side of the pressure stabilizing valve. An automatic regulating valve is fixedly connected to the front side of the diverter body. A delivery pipe is fixedly connected to the front side of the automatic regulating valve. A flow meter is fixedly connected to the front side of the delivery pipe. A connecting pipe is fixedly connected to the front side of the flow meter.

[0010] Preferably, the bottom of the sealing cap is in contact with the top of the liquid storage tank, a water inlet pipe is fixedly connected to the top rear side of the liquid storage tank, and a scale line is fixedly connected to the left side of the liquid storage tank, so as to facilitate sealing the top of the liquid storage tank through the sealing cap.

[0011] Preferably, the water pump is fixedly connected to the top of the base, and a support seat is fixedly connected to the bottom of the automatic regulating valve. The support seat is fixedly connected to the front side of the base, so that the automatic regulating valve can be supported by the support seat.

[0012] Preferably, the fixing frame and hydraulic cylinder are provided in two sets and symmetrically distributed on the left and right sides of the top of the sealing cover, so as to ensure the stability of the movement of the sealing cover by setting two sets.

[0013] Preferably, the automatic regulating valve, support base, delivery pipe, flow meter and connecting pipe are provided in four sets, and are symmetrically distributed on the front side of the diverter body, so as to facilitate the diversion function by setting four sets.

[0014] Preferably, the stirring mechanism includes a servo motor, which is fixedly connected to the top of the sealing cover. A rotating rod is fixedly connected to the bottom of the servo motor, and the rotating rod is rotatably connected to the inside of the sealing cover. A stirring shaft is fixedly connected to the periphery of the rotating rod, and a stirring disc is fixedly connected to the bottom of the rotating rod.

[0015] Preferably, the stirring shaft and the stirring plate are rotatably connected to the inside of the storage tank, which facilitates the mixing of high-concentration fertilizer solution with irrigation water through the stirring shaft and the stirring plate.

[0016] Compared with the prior art, this utility model provides a diverter structure for precision fertilization in an integrated water and fertilizer machine, which has the following beneficial effects:

[0017] 1. The precision fertilization distributor structure of this integrated water and fertilizer machine, through its designed distributor mechanism, allows for precise fertilization when fertilization is required. A hydraulic cylinder moves the sealing cover to the top of the storage tank, sealing it. Simultaneously, the external irrigation water supply pipe is connected to the inlet pipe, and the external spray pipe is connected to the connecting pipe. Irrigation water is added according to the scale markings, and the pre-mixed high-concentration fertilizer solution is added from the top of the sealing cover. After mixing by the stirring mechanism, the water pump delivers the solution from the storage tank to the distributor body through the delivery pipe. The pressure stabilizing valve at the front of the delivery pipe effectively stabilizes the output from the storage tank. The pressure of water and fertilizer is controlled to avoid unstable flow in each diversion channel due to pressure fluctuations, ensuring the stability of the water and fertilizer delivery process. When water and fertilizer are diverted through the diverter, they are delivered to the external spray pipes through the delivery pipes and connecting pipes for fertilization. The flow meter can monitor the water and fertilizer flow in each channel in real time. According to the fertilizer requirements of different crops and different growth stages, the staff can accurately control the water and fertilizer delivery of each channel through the automatic regulating valve. The flow regulation accuracy is higher. This multi-channel independent control diversion mode not only improves the efficiency of fertilization operations, but also meets the differentiated fertilization needs of different crops in the same field or different areas of the same crop.

[0018] 2. The precision fertilization diverter structure of this integrated water and fertilizer machine, through its set stirring mechanism, when fertilization is required and irrigation water and high-concentration fertilizer solution are mixed in proportion and put into the storage tank, the servo motor drives the rotating rod to drive the stirring shaft and stirring plate to rotate synchronously. The stirring shaft can perform three-dimensional stirring of the water and fertilizer in the storage tank in both longitudinal and transverse directions, while the stirring plate can fully stir the fertilizer particles at the bottom of the storage tank, avoiding fertilizer sedimentation and clumping. This ensures that the fertilizer and water can quickly mix to form a uniform water and fertilizer solution, eliminating the problem of localized excessively high or low fertilizer concentrations caused by uneven mixing from the source.

[0029] This utility model provides the following technical solution:

[0030] Example 1

[0031] Please see Figure 1-6 This utility model provides a technical solution: a diverter structure for precision fertilization of an integrated water and fertilizer machine, including a base 1, a diverter mechanism 2 is provided on the top of the base 1, and a stirring mechanism 3 is provided inside the diverter mechanism 2;

[0032] The diversion mechanism 2 includes a liquid storage tank 21, which is fixedly connected to the top of the base 1. A fixing frame 23 is fixedly connected to the top of the liquid storage tank 21. A hydraulic cylinder 24 is fixedly connected to the top of the fixing frame 23. A sealing cover 25 is fixedly connected to the bottom of the hydraulic cylinder 24. The sealing cover 25 is located on the top of the liquid storage tank 21. A liquid delivery pipe 26 is fixedly connected to the bottom of the front side of the liquid storage tank 21. A water pump 28 is fixedly connected to the periphery of the liquid delivery pipe 26. A pressure stabilizing valve 29 is fixedly connected to the front side of the liquid delivery pipe 26. A diverter body 291 is fixedly connected to the front side of the pressure stabilizing valve 29. An automatic regulating valve 293 is fixedly connected to the front side of the diverter body 291. A delivery pipe 294 is fixedly connected to the front side of the automatic regulating valve 293. A flow meter 295 is fixedly connected to the front side of the delivery pipe 294. A connecting pipe 296 is fixedly connected to the front side of the flow meter 295.

[0033] The bottom of the sealing cap 25 is in contact with the top of the liquid storage tank 21. A water inlet pipe 22 is fixedly connected to the top rear side of the liquid storage tank 21. A scale line 27 is fixedly connected to the left side of the liquid storage tank 21, so as to facilitate sealing the top of the liquid storage tank 21 through the sealing cap 25.

[0034] The water pump 28 is fixedly connected to the top of the base 1, and the automatic regulating valve 293 is fixedly connected to the bottom of the support seat 292. The support seat 292 is fixedly connected to the front side of the base 1, so that the automatic regulating valve 293 can be supported by the support seat 292.

[0035] Two sets of fixed brackets 23 and hydraulic cylinders 24 are provided and symmetrically distributed on the left and right sides of the top of the sealing cover 25, so that the stability of the movement of the sealing cover 25 can be ensured by setting two sets.

[0036] The automatic regulating valve 293, support base 292, delivery pipe 294, flow meter 295 and connecting pipe 296 are provided in four sets and are symmetrically distributed on the front side of the diverter body 291, so that the diversion function can be achieved by setting four sets.

[0037] Example 2

[0038] Please see Figure 1-6 Furthermore, based on Embodiment 1, the stirring mechanism 3 further includes a servo motor 31, which is fixedly connected to the top of the sealing cover 25. A rotating rod 32 is fixedly connected to the bottom of the servo motor 31. The rotating rod 32 is rotatably connected to the inside of the sealing cover 25. A stirring shaft 33 is fixedly connected to the periphery of the rotating rod 32. A stirring plate 34 is fixedly connected to the bottom of the rotating rod 32.

[0039] The stirring shaft 33 and the stirring plate 34 are rotatably connected to the inside of the liquid storage tank 21, which facilitates the mixing of high-concentration fertilizer solution with irrigation water through the stirring shaft 33 and the stirring plate 34.

[0040] In actual operation, when this device is used, when fertilization is required through the water and fertilizer integrated machine, the hydraulic cylinder 24 drives the sealing cover 25 to move to the top of the storage tank 21 to seal it. At the same time, the external irrigation water supply pipe is connected to the water inlet pipe 22, the external spray pipe is connected to the connecting pipe 296, and irrigation water is added according to the scale line 27. At the same time, the high-concentration fertilizer solution prepared is poured in from the top of the sealing cover 25.

[0041] When irrigation water and high-concentration fertilizer solution are mixed in proportion and added to the storage tank 21, the servo motor 31 drives the rotating rod 32 to drive the stirring shaft 33 and the stirring plate 34 to rotate synchronously. The stirring shaft 33 can perform vertical and horizontal three-dimensional stirring of the water and fertilizer in the storage tank 21, while the stirring plate 34 can fully stir the fertilizer particles at the bottom of the storage tank 21 to avoid fertilizer sedimentation and clumping. This ensures that the fertilizer and water can quickly blend to form a uniform water and fertilizer solution, thus eliminating the problem of local fertilizer concentration being too high or too low due to uneven mixing from the source.

[0042] After mixing, the water pump 28 delivers the water and fertilizer in the storage tank 21 to the distributor body 291 through the delivery pipe 26. The pressure stabilizing valve 29 on the front side of the delivery pipe 26 can effectively stabilize the pressure of the water and fertilizer output from the storage tank 21, avoiding unstable flow in each distribution channel due to pressure fluctuations, and ensuring the smoothness of the water and fertilizer delivery process. When the water and fertilizer are distributed through the distributor body 291, they will be delivered to the external spray pipes for fertilization through the delivery pipe 294 and the connecting pipe 296. The flow meter 295 can monitor the water and fertilizer flow in each channel in real time. According to the fertilizer requirements of different crops and different growth stages, the staff can accurately control the water and fertilizer delivery of each channel through the automatic regulating valve 293. The flow regulation accuracy is higher. This multi-channel independent control distribution mode not only improves the efficiency of fertilization operations, but also meets the differentiated fertilization needs of different crops in the same field or different areas of the same crop. At the same time, it can also ensure the uniformity of water and fertilizer in each group of spray pipes and ensure the quality of fertilization.

[0043] The automatic regulating valve 293, support base 292, delivery pipe 294, flow meter 295 and connecting pipe 296 are provided in four sets and symmetrically distributed on the front side of the diverter body 291. By setting four sets, each delivery pipe 294 can be individually adjusted and controlled to ensure the uniformity and accuracy of the diversion.

[0044] The pressure regulating valve 29 used in this case is the YX741X series, the automatic regulating valve 293 is the BERMAD IR-200 series, and the flow meter 295 is the Siemens SITRANS FUS880.

[0045] In use, all hydraulic cylinders 24, water pumps 28, pressure stabilizing valves 29, automatic regulating valves 293, flow meters 295, and servo motors 31 need to be connected to the same external automation controller to achieve automated operation. The automation controller is existing technology, and those skilled in the art are well aware of its operation method, so it will not be described in detail here.
