Description

Technical Field

[0001] The utility model belongs to the technical field of farmland irrigation equipment, in particular to a self-generating intelligent water-powered fertilizer applicator. Background Art

[0002] Water-fertilizer integration technology refers to a new agricultural technology that integrates irrigation and fertilization. Water-fertilizer integration is to use a pressure system (or natural terrain drop) to mix soluble solid or liquid fertilizers according to the soil nutrient content and the fertilizer requirements and characteristics of the crop types, and mix them with irrigation water to supply water and fertilizer through a pipeline system. After the water and fertilizer are mixed, drip irrigation is formed through pipes and drippers to evenly, regularly, and quantitatively infiltrate the root development and growth area of ​​the crop, so that the main root soil always remains loose and has an appropriate water content.

[0003] The hydrodynamic fertilizer applicator is one of the indispensable devices in the integrated water and fertilizer fertilization work. By reducing the opening angle of the valve on the main pipe, the water flow rate flowing into the branch pipe can be increased, so that the flow rate of irrigation water can be used to generate the power to absorb fertilizer, and the water and fertilizer are sucked into the main pipe through the straw and mixed with the irrigation water to achieve water supply and fertilizer supply. However, the valve on the existing hydrodynamic fertilizer applicator is manually adjusted, and the size of the water flow flowing into the branch pipe cannot be accurately adjusted. Therefore, the control of the fertilizer absorption capacity is not accurate enough, and the concentration of fertilizer in the irrigation water cannot be accurately adjusted, and automatic and information control cannot be achieved. At the same time, the existing hydrodynamic fertilizer applicator can only absorb a single fertilizer into the irrigation water at the same time, and cannot simultaneously transport different types of fertilizers to the irrigation pipe.

[0032] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] Reference Figure 1-Figure 7 The utility model provides a self-generating intelligent water-powered fertilizer applicator, comprising:

[0034] A main pipe 1, which is connected to a main solenoid valve 30, one end of which is connected to a farm irrigation pipe, and a flow meter is disposed inside the other end of the main pipe 1;

[0035] A plurality of fertilizer pumping components, the fertilizer pumping components include branch pipes 14, both ends of the plurality of branch pipes 14 are respectively connected to the main pipeline 1, and the main solenoid valve 30 is located between the water inlet end and the water outlet end of the plurality of branch pipes 14, a water-driven rotating member is arranged in the branch pipe 14, and a plurality of water pumps 17 are arranged on the branch pipe 14, the water-driven rotating member is used to drive the plurality of water pumps 17 to rotate, and the plurality of water pumps 17 are used to pump water fertilizer;

[0037] The power generation component includes a front-end pipeline 2 connected to the main pipeline 1 away from one end of the farmland irrigation pipeline. A water-driven power generation mechanism is arranged in the front-end pipeline 2. The water-driven power generation mechanism is used to supply power to the main solenoid valve 30, the branch pipe mechanism, the flow meter and the concentration meter.

[0038] The main function of the main solenoid valve 30 is to limit the water flow through the main pipeline 1 so that part of the irrigation water flows into the branch pipe 14; the main function of the flow meter is to detect the water flow flowing into the main pipeline 1; the main function of the water-driven rotating member is to rotate under the impact of the water flow in the branch pipe 14 to provide power for the operation of the water pump 17; the main function of the water pump 17 is to absorb water fertilizer and send the water fertilizer into the main pipeline 1 to mix with the irrigation water; the main function of the concentration meter is to measure the concentration of the absorbed water fertilizer; the main function of the branch pipe mechanism is to transport the fertilizer absorbed by each water pump 17 to the main pipeline 1; the main function of the water-driven generator is to generate electricity by using the impact of the irrigation water flow, and to power the main solenoid valve 30, the branch pipe mechanism, the flow meter and the concentration meter. On the whole, the utility model can monitor the mixing ratio of water and fertilizer in real time by detecting the water flow and the concentration of fertilizer, and use the main solenoid valve to automatically adjust the ratio of water flow into the main pipeline and the branch pipe, thereby controlling the power of the water pump to control the fertilization speed entering the pipeline system, so as to achieve the purpose of uniform fertilization and precise fertilization. Secondly, by connecting multiple branch pipes to the main pipe, the irrigation water flow can drive multiple water pumps to work at the same time, so as to absorb different fertilizers at the same time. At the same time, the irrigation water flow is used to generate electricity to supply the operation of each functional module. It can work in the field without external power supply, and can achieve the purpose of green environmental protection.

[0039] To further optimize the scheme, a controller and a transmitter are also provided. The main function of the controller is to receive the measured values ​​of the flow meter and the concentration meter, and at the same time, it can control the action of the main electromagnetic valve 30 and the branch pipe mechanism. The main function of the transmitter is to transmit the measured values ​​received by the controller to the terminal database, and at the same time receive the instructions of the terminal and transmit the instructions to the controller, so as to realize automation, informatization and remote control.

[0040] According to a further optimized solution, the water inlet of the water pump 17 is connected to one end of a hose, and the other end of the hose extends into the fertilizer water in the open fertilizer barrel.

[0041] To further optimize the solution, the main pipeline 1 is connected with a front-stage collar 7 and a rear-stage collar 8, which are respectively located at the two ends of the main solenoid valve 30, the front-stage collar 7 is connected with a plurality of front-stage pipes 33, the rear-stage collar 8 is connected with a plurality of rear-stage pipes 9, the two ends of the side wall of the branch pipe 14 are respectively connected with a front-stage connector 12 and a rear-stage connector 13, the front-stage connector 12 and the rear-stage connector 13 on the branch pipe 14 are respectively connected with a front-stage pipe 33 and a rear-stage pipe 9.

[0042] In a further optimized solution, both ends of the branch pipe 14 are set as closed structures, and water flows into the branch pipe 14 through the front-stage joint 12 and flows out from the rear-stage joint 13. Depending on the work needs, two sets of water pumps 17 are fixedly connected at both ends of the branch pipe 14 or one set of water pumps 17 is fixedly connected at one end.

[0043] The main functions of the front-stage collar 7 and the rear-stage collar 8 are to provide a plurality of front-stage pipes 33 and a plurality of rear-stage pipes 9. Figure 1 and Figure 2 As shown, two groups of front-stage connecting pipes 33 are arranged on the front-stage collar 7, and two groups of rear-stage connecting pipes 9 are arranged on the rear-stage collar 8, which can be connected to two groups of branch pipes 14 at the same time. The water-driven rotating parts in the two groups of branch pipes 14 can respectively drive the water pumps 17 on the corresponding branch pipes 14 to operate, so as to achieve the purpose of absorbing different fertilizers at the same time, or make multiple water pumps 17 absorb the same fertilizer at the same time, thereby improving the efficiency of fertilization.

[0044] According to a further optimized solution, the front-stage pipe 33 and the rear-stage pipe 9 are respectively connected to a front-stage solenoid valve 10 and a rear-stage solenoid valve 11 .

[0045] like Figure 2 As shown, the front-stage solenoid valve 10 and the rear-stage solenoid valve 11 are electrically connected to the controller, and their main function is to control the water flow into the corresponding branch pipe 14 by controlling the size of the opening and closing. When the opening of the main solenoid valve 30 remains unchanged, the size of the water flow into the two groups of branch pipes 14 can be controlled by adjusting the opening and closing of the front-stage solenoid valve 10 and the rear-stage solenoid valve 11, thereby accurately controlling the operating power of the water pumps 17 on the two groups of branch pipes 14, and achieving different pumping effects between the water pumps 17.

[0046] like Figure 1 As shown, when the front-stage pipe 33 and the rear-stage pipe 9 are not connected to the branch pipe 14, the controller controls the front-stage solenoid valve 10 and the rear-stage solenoid valve 11 to be in a closed state to prevent the irrigation water from flowing out.

[0047] A further optimized solution is that the water-driven rotating member includes a transmission shaft 16 rotatably connected in the branch pipe 14, and a plurality of impellers 15 are fixedly connected to the transmission shaft 16 along the axial direction of the transmission shaft 16. The plurality of impellers 15 are located in the middle of the branch pipe 14, and the transmission shaft 16 is transmission-connected to the input shaft of the water pump 17.

[0048] like Figure 3 As shown, a plurality of support rods 29 are fixedly connected in the branch pipe 14, and the transmission shaft 16 is rotatably connected in the branch pipe 14 through the plurality of support rods 29. When water flows in from the front-stage joint 12 and flows out from the rear-stage joint 13, the water flows impact the plurality of impellers 15, and the rotation of the impellers 15 drives the transmission shaft 16 to rotate. The two ends of the transmission shaft 16 penetrate the two end side walls of the branch pipe 14 and drive the input shafts of the two groups of water pumps 17 to rotate, so that the water pumps 17 start to work.

[0049] A further optimized solution is that the branch pipe mechanism includes a connection box 21 connected to the end of the water inlet pipe 20 away from the main line 1, a plurality of water inlet branch pipes 22 are connected to the connection box 21, and a plurality of water inlet branch pipes 22 are respectively connected to fertilizer solenoid valves 31, a water outlet 19 of a water pump 17 is connected to a water inlet branch pipe 22 through a pipeline, an exhaust part is provided on the water inlet branch pipe 22, and the fertilizer solenoid valve 31 is arranged between the exhaust part and the connection box 21.

[0050] like Figure 4 As shown, each water pump 17 pours the sucked water and fertilizer into the connection box 21 through a water inlet branch pipe 22, and after mixing in the connection box 21, flows into the main pipeline 1 through the water inlet pipe 20 to mix with the irrigation water. The main function of the fertilizer solenoid valve 31 is to prevent water from flowing out of the water inlet branch pipe 22 by closing the fertilizer solenoid valve 31 when the corresponding water inlet branch pipe 22 is not connected to the water pump 17.

[0051] A further optimized solution is provided, the exhaust part includes an exhaust pipe 23 connected to the side wall of the water inlet branch pipe 22, the exhaust pipe 23 is located at one end of the water inlet branch pipe 22 away from the connecting box 21, an opening 27 is provided on the exhaust pipe 23, an exhaust valve block 25 is slidably connected in the exhaust pipe 23, a position adjustment member is provided between the exhaust valve block 25 and the exhaust pipe 23, an exhaust channel 26 is provided in the exhaust valve block 25, when the exhaust valve block 25 is located in the exhaust pipe 23, the water and fertilizer pumped by the water pump 17 enter the connecting box 21 through the water inlet branch pipe 22, when the exhaust valve block 25 slides from the exhaust pipe 23 to the water inlet branch pipe 22, the water, fertilizer and air pumped by the water pump 17 flow out through the exhaust channel 26 and the opening 27.

[0052] A further optimized solution is that the position adjustment component includes a pressing rod 24 fixedly connected to the side of the exhaust valve block 25 away from the water inlet branch pipe 22, and one end of the pressing rod 24 away from the exhaust valve block 25 passes through the side wall of the exhaust pipe 23. A spring 28 is sleeved on the pressing rod 24, and both ends of the spring 28 are respectively fixedly connected between the exhaust pipe 23 and the exhaust valve block 25.

[0053] like Figure 6 and Figure 7 As shown, during use, such as when replacing a fertilizer barrel, the water pump 17 is prone to inhaling air, which reduces the water pumping capacity of the water pump 17. The existing fertilizer applicator needs to manually remove the connecting pipe to exhaust the air and then install it again to operate normally. In the present application, when there is no air in the pipeline, the exhaust valve block 25 is in the exhaust pipe 23 under the tension of the spring 28, and the fertilizer water flows directly into the connecting box 21 through the water inlet branch 22. When there is air in the pipeline that needs to be exhausted, the operator presses the pressing rod 24 inward, the spring 28 is stretched, and the exhaust valve block 25 moves into the water inlet branch 22 to block the water inlet branch 22. The fertilizer water and air flow into the exhaust pipe 23 through the exhaust channel 26 and are discharged from the opening 27. When the liquid is continuously and stably discharged from the opening 27, it means that the exhaust is complete, and the pressing rod 24 can be released.

[0054] A further optimized solution is that the water-driven power generation mechanism includes a generator 4 fixedly connected to the front-end pipeline 2, a rotating shaft 6 is coaxially fixedly connected to the transmission shaft of the generator 4, the axis of the rotating shaft 6 coincides with the axis of the front-end pipeline 2, and a spiral blade 5 is fixedly connected to the rotating shaft 6.

[0055] like Figure 1 and Figure 5 As shown, one end of the front-end pipeline 2 close to the generator 4 is connected to the water inlet pipe 3. Irrigation water flows into the front-end pipeline 2 from the water inlet pipe 3. When the water flows in the front-end pipeline 2, it impacts the spiral blades 5. The spiral blades 5 rotate under the impact and drive the rotating shaft 6 to rotate. The rotation of the rotating shaft 6 drives the generator 4 to rotate and generate electricity, providing power for the operation of the flow meter, the concentration meter, the front-stage solenoid valve 10, the rear-stage solenoid valve 11, the main solenoid valve 30 and the fertilizer solenoid valve 31.

[0056] To further optimize the solution, the water inlet end of the front-end pipeline 2 is connected to a backwashing device 32.

[0057] like Figure 1 As shown, the main function of the backwash device 32 is to filter the water flowing into the main pipe 1 to prevent sediment from entering the impeller 15 and damaging the equipment. When the flow meter detects that the flow rate is reduced to a set threshold, the backwash device 32 can flush the filter screen inside it. Since the backwash device 32 is a prior art, its working principle and process will not be described in detail.

[0058] The working process of this embodiment is as follows: according to the type of fertilizer to be applied, a corresponding number of branch pipes 14 are installed, and one or two water pumps 17 are installed on the branch pipes 14. After that, the water inlet 18 of each water pump 17 is connected to the inside of the fertilizer barrel, and the water outlet 19 is connected to the water inlet branch pipe 22 through a pipe. Before working, the front-stage solenoid valve 10 and the rear-stage solenoid valve 11 are in a closed state, the main solenoid valve 30 is in a fully open state, and the fertilizer solenoid valve 31 is in a closed state. After the irrigation water is introduced from the water inlet pipe 3, the generator 4 generates electricity to provide electricity. At this time, the corresponding front-stage solenoid valve 10, the rear-stage solenoid valve 11 and the fertilizer solenoid valve 31 are opened through the terminal control, and the main solenoid valve 30 is controlled to close a certain angle, so that the water flow enters the branch pipe 14, and the water flow impacts the impeller 15 to make the water pump 17 work, and the fertilizer water is transported to the main pipeline 1 through the water inlet branch pipe 22 to mix with the irrigation water. During the process of irrigation and fertilization, the flow meter and concentration meter are used to monitor the irrigation water volume, fertilizer concentration and other information of the farmland. At the same time, the terminal controls the opening and closing size of the main electromagnetic valve 30, controls the water flow size flowing into the branch pipe 14, thereby adjusting the power of the water pump 17 and controlling the fertilization speed entering the pipeline system, so as to achieve the purpose of uniform fertilization and precise fertilization.

[0059] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0060] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
