Description

Technical Field

[0001] The utility model relates to the technical field of integrated water and fertilizer drip irrigation devices, in particular to a precise integrated water and fertilizer drip irrigation control device for wheat and corn. Background Technique

[0002] At present, agricultural water use in the main grain-producing areas of our country is faced with the dual problems of serious water resource shortage and serious waste. Most of the corn production still adopts traditional furrow irrigation and flood irrigation methods, which have problems such as excessive water consumption, serious overexploitation of groundwater, and low agricultural water use efficiency. At the same time, the traditional flood irrigation method also leads to a large amount of nitrogen fertilizer leaching, resulting in serious agricultural non-point source pollution and soil quality decline, posing a great threat to grain production and food security. In addition, the asynchronous supply of water and fertilizer in traditional irrigation leads to late-stage fertilizer deficiency and premature senescence of corn in the middle and late stages, low fertilizer utilization rate, and seriously affects the yield. With the increasing shortage of future agricultural water resources and the improvement of the requirements for the quality of the agricultural ecological environment, it is necessary to explore a water-saving, fertilizer-saving and efficient irrigation and fertilization mode in corn production. As an irrigation method with high water and fertilizer utilization efficiency, drip irrigation can supply water and nutrients regularly and quantitatively according to the needs of different growth stages of crops, achieving the comprehensive effects of water saving, high quality and high yield.

[0003] Therefore, the patent number is publicly disclosed as: CN220965919U, which discloses a timed drip irrigation device for pear tree planting, including a liquid storage barrel and a rain collection tray. Two liquid injection pipes are connected to the liquid storage barrel. A liquid distribution seat is arranged at the center of the inner bottom of the liquid storage barrel. A plurality of drip irrigation pipes are fixedly connected to the bottom of the liquid storage barrel. A stirring assembly is arranged in the liquid storage barrel. The stirring assembly includes a stirring motor and a scraping bar. The stirring motor is fixedly installed at the center of the bottom of the liquid storage barrel and the output end is fixedly installed with a transmission shaft. The transmission shaft is rotatably installed in the liquid distribution seat and the top end is fixedly connected to the scraping bar. A plurality of stirring rods are integrally formed on the inner side of the scraping bar. A connection assembly is arranged on the drip irrigation pipe. The connection assembly includes a hanging seat and a screw head. A hanging ring is arranged at the top of the hanging seat. Bellows are connected to both ends of the hanging seat; this drip irrigation device is used for pear tree planting. Through an external control terminal, timed drip irrigation can be controlled, and it has the function of stirring and preventing precipitation. At the same time, the drip irrigation spacing can be adjusted according to the planting spacing of pear trees.

[0004] In the above solution, it is impossible to accurately control the amount of fertilizer and water for drip irrigation each time. It is necessary to manually adjust the drip irrigation switch. And during the process of pipeline drip irrigation, the number of drip holes on some drip irrigation pipes is relatively large. Generally, a valve is set at the connection between the drip irrigation pipe and the delivery pipe to control the delivery of water and fertilizer from the delivery pipe to the drip irrigation pipe, so as to stop or start drip irrigation. However, the drip irrigation pipe is relatively long. When the delivery pipe delivers water and fertilizer to the drip irrigation pipe, the water and fertilizer will first pass through the drip holes closer to the valve, so that the drip irrigation will start in sequence, resulting in differences in the drip irrigation amount of plants, which is not conducive to accurately controlling the drip irrigation amount.

[0022] The embodiment of the utility model provides a precise water and fertilizer integrated drip irrigation control device for wheat and corn.

[0023] Please refer to Figures 1 to 4 , the precise water and fertilizer integrated drip irrigation control device for wheat and corn, including the following embodiments:

[0024] It includes a mixed fertilizer water tank, the bottom of the mixed fertilizer water tank is fixedly connected with a support frame for support, a plurality of metering tanks are arranged at the bottom of the mixed fertilizer water tank, a liquid inlet pipe is fixedly communicated between the plurality of metering tanks and the bottom of the mixed fertilizer water tank, and the plurality of metering tanks are all fixedly connected with the support frame. A metering control component is arranged inside each of the plurality of metering tanks for controlling the metering of each drip irrigation.

[0025] The tops of the plurality of metering tanks are all fixedly connected with liquid outlet pipes, and a plurality of drip irrigation components are arranged on the outer sides of the plurality of liquid outlet pipes.

[0026] A stirring frame is arranged inside the mixed fertilizer water tank, the stirring frame penetrates through the mixed fertilizer water tank and is rotatably connected with the mixed fertilizer water tank. A driving motor is fixedly connected to the outside of the mixed fertilizer water tank, the output shaft of the driving motor is fixedly connected with the stirring frame, and a feed pipe is fixedly communicated with the top of the mixed fertilizer water tank.

[0027] During specific implementation: The fertilizer and water are introduced into the mixed fertilizer water tank through the feed pipe. At this time, by starting the driving motor, the output shaft of the driving motor drives the stirring frame to rotate, and the stirring frame fully mixes and stirs the fertilizer and water, and then conveys them to the inside of the metering tanks through the liquid inlet pipes respectively. By controlling the space inside the metering tanks, precise control of the quantitative drip irrigation in different areas can be achieved.

[0028] Please refer to Figure 3 , in this embodiment, the metering control component includes a pressing plate arranged inside the metering tank. A sliding plate is arranged at the bottom of the pressing plate, and a first electric telescopic rod is fixedly connected between the sliding plate and the pressing plate. The top of the support frame is fixedly connected with a second electric telescopic rod, and the telescopic end of the second electric telescopic rod penetrates through the metering tank and is fixedly connected with the sliding plate.

[0029] During specific implementation, by setting a one-way liquid inlet valve and a control valve on the outer side of the liquid inlet pipe, and a one-way liquid outlet valve on the outer side of the liquid outlet pipe. When it is necessary to quantify the liquid inside the metering tank, by starting the first electric telescopic rod between the pressing plate and the sliding plate, the position of the pressing plate inside the metering tank is adjusted, and then the amount of the fertilizer and water inside the metering tank can be adjusted according to needs. When it is necessary to discharge, by starting the second electric telescopic rod, the second electric telescopic rod pushes the sliding plate and then pushes the pressing plate through the first electric telescopic rod, so that the pressing plate continuously rises to discharge the fertilizer and water through the liquid outlet pipe.

[0030] Please refer to Figure 4, Embodiment 2: The drip irrigation assembly includes a fixing cylinder sleeved outside the liquid outlet pipe. The fixing cylinder is fixedly connected to the liquid outlet pipe. A plurality of liquid outlet grooves for liquid outlet are formed on the outside of the liquid outlet pipe, and drip irrigation holes are formed on the outside of the fixing cylinder.

[0031] The drip irrigation assembly further includes a blocking plate. The blocking plate is sleeved outside the liquid outlet pipe and is slidably connected to the liquid outlet pipe. The blocking plate is arranged between the liquid outlet groove and the drip irrigation hole. A plurality of return springs are arranged between the blocking plate and one end of the fixing cylinder. Both ends of the plurality of return springs are fixedly connected to the inner end of the fixing cylinder and the blocking plate respectively. When the liquid outlet groove discharges liquid, the blocking plate is pushed to move, so that the fertilizer water is drip-irrigated through the drip irrigation holes.

[0032] During specific implementation, in the actual drip irrigation process, when the water and fertilizer are transported from the conveying pipe to the drip irrigation pipe, the water and fertilizer will first pass through the drip irrigation holes closer to the valve, which will cause the drip irrigation to start in sequence, resulting in differences in the drip irrigation amount and being not conducive to accurately controlling the drip irrigation amount. Therefore, in this solution, by setting the liquid outlet pipe and setting the liquid outlet pipe as a small-size pipe, the fertilizer water can quickly fill the inside of the liquid outlet pipe and be discharged into the fixing cylinder through the liquid outlet grooves on the outside of the liquid outlet pipe. As the water flushes in, the blocking plate is continuously squeezed. When the blocking plate is pushed to move to one side of the drip irrigation hole, the plants are drip-irrigated through the drip irrigation holes, so as to reach each drip irrigation position and keep the water output consistent;

[0033] And when the water volume decreases in the later stage, in order to ensure that the fertilizer water inside the fixing cylinder can be completely discharged, small holes are formed on the outside of the blocking plate. The remaining liquid in the later stage can flow through the small holes through the blocking plate and then flow out through the drip irrigation holes. The water flow of the small holes is small, so it will not affect the normal movement of the blocking plate.

[0034] In this embodiment: A protection plate for protection is arranged below the drip irrigation hole. One side of the protection plate is fixedly connected with a connecting rod. The connecting rod penetrates through the fixing cylinder and is slidably connected to the fixing cylinder. The connecting rod is fixedly connected to the blocking plate.

[0035] During specific implementation, since the drip irrigation holes are exposed to the outside and the dust outside is likely to cause blockage of the drip irrigation holes, a protection plate is set in this solution. When the blocking plate moves, the protection plate is driven to move through the connecting rod, and the protection plate is moved away from below the drip irrigation holes, so as to protect the drip irrigation holes. It should be noted that the protection plate does not fit the surface of the fixing cylinder, so that the remaining fertilizer water can flow out normally.

[0036] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
