Description

Technical Field

[0001] This utility model relates to the field of drip irrigation technology, specifically a drip irrigation device under film for sorghum planting. Background Technology

[0002] Sorghum is an important food crop with high drought resistance and adaptability, and is widely cultivated in northern my country and some arid regions. Sorghum is quite sensitive to water requirements during its growth process, and proper irrigation is crucial for improving sorghum yield and quality.

[0003] Subsurface drip irrigation refers to the application of drip irrigation technology under a mulch film. This is a new water-saving technology that combines the advantages of Israeli drip irrigation technology and domestic mulching technology. This technology supplies water through a controllable pipeline system. Pressurized water is filtered through a filtration facility and then fully mixed with water-soluble fertilizer to form a fertilizer solution. This solution enters the main water supply pipe, branch pipe, and capillary pipe (the irrigation strip laid under the mulch film). Then, the drippers on the capillary pipes evenly, regularly, and quantitatively irrigate the crop root development zone for root absorption.

[0004] A review of the public announcement (CN218218629U) reveals a water-saving drip irrigation device under a film membrane. This technology discloses that it "includes a mixing drum, inside which a mixing mechanism is provided. The mixing mechanism includes a support column, two bevel gears, and a fixed rod. A rotating tube is rotatably connected to the outer surface of the support column, and a bevel gear is fixedly connected to the outer surface of the rotating tube. Through the mixing mechanism and other technical solutions, it can fully mix the nutrients and water in the mixing drum, ensuring thorough integration of the materials and water, effectively preventing undissolved nutrients from directly drip-irrigating and clogging the outlet holes of the capillary tubes, thus preventing some capillary tubes from performing drip irrigation."

[0005] The above design, while ensuring thorough mixing and fusion of nutrients and water in the mixing drum through the stirring mechanism, requires repeated stirring to prevent nutrient sedimentation at the bottom of the mixing drum during each drip irrigation. This frequent stirring, driven by a motor, increases energy consumption, raises operating costs, and reduces the device's effectiveness. Therefore, we propose a drip irrigation device under film for sorghum cultivation to address these issues. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a drip irrigation device under film for sorghum planting, which solves the problem that in order to prevent nutrients from settling at the bottom of the mixing tank during each drip irrigation, frequent stirring is required, which increases energy consumption and operating costs due to motor drive.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a drip irrigation device under film for sorghum planting, including a mixing tank, a connecting pipe fixedly connected to the bottom surface of the outer side of the mixing tank, a water pump placed on one side of the outer side of the mixing tank, a main pipe fixedly installed at the output end of the water pump, multiple sets of drip irrigation capillary tubes fixedly connected to the surface of the main pipe, the input end of the water pump and one end of the connecting pipe fixedly connected, and a cover plate provided at the top opening of the mixing tank;

[0008] A U-shaped frame is fixed to the lower surface of the cover plate;

[0009] The U-shaped frame is rotatably mounted with a stirring rod via a bearing.

[0010] A water turbine fan is fixedly installed at the top of the stirring rod;

[0011] The surface of the U-shaped frame is fixedly fitted with bent pipes by a support plate;

[0012] A water supply pipe is fixedly connected to the surface of the main pipe. One end of the bend extends through the top of the cover plate and is fixedly connected to one end of the water supply pipe. A control valve is installed on the surface of the main pipe at the position between the water supply pipe and the drip irrigation capillary tube.

[0013] Preferably, a nozzle is fixedly installed at the other end of the bend, the nozzle being opposite to the edge of the water turbine fan, and a filter mechanism body is installed on the cover plate.

[0014] Preferably, a solenoid valve is installed on the bend.

[0015] Preferably, a waterproof cover for waterproofing the solenoid valve is fixedly installed on the lower surface of the cover plate.

[0016] Preferably, a handle is fixedly installed on the upper surface of the cover plate.

[0017] Preferably, the cover plate is provided with multiple sets of locking bolts, the cover plate has threaded holes adapted to the locking bolts, the edge surface of the mixing tank has locking grooves adapted to the locking bolts, the locking bolts pass through the threaded holes and are screwed into the locking grooves for connecting and locking the cover plate and the mixing tank.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1 As shown:

[0028] A drip irrigation device for sorghum planting includes a mixing tank 101. A connecting pipe 102 is fixedly connected to the bottom outer surface of the mixing tank 101. A water pump 103 is placed on one side of the mixing tank 101. A main pipe 104 is fixedly installed at the output end of the water pump 103. Multiple sets of drip irrigation capillaries 105 are fixedly connected to the surface of the main pipe 104. The input end of the water pump 103 is fixedly connected to one end of the connecting pipe 102.

[0029] In this implementation plan: To address the technical problems existing in the prior art, as disclosed in the background section above, "Although the above design, through the setting of the stirring mechanism, allows the nutrients and water in the stirring drum to be fully stirred and fully mixed, and the nutrient solution is transported out by the water pump, a stirring operation is required every time drip irrigation is performed to ensure that the nutrients do not settle at the bottom of the stirring drum. Frequent stirring, driven by a motor, increases energy consumption, raises operating costs, and reduces the effectiveness of the device." In terms of usage, this problem is clearly a real and difficult-to-solve issue. Therefore, to solve this technical problem, all electrical equipment involved in this product is powered by an external power source. The solution also includes a control module, which is set on the stirring drum 101. During use, the electrical equipment can be started through the control module. The power connection method of the electrical equipment is a mature existing technology, which is well known to those skilled in the art and will not be elaborated further here.

[0030] Furthermore:

[0031] like Figures 1-4 As shown:

[0032] Based on the above: The top opening of the mixing tank 101 is provided with a cover plate 107, and a handle 117 is fixedly installed on the upper surface of the cover plate 107.

[0033] A U-shaped bracket 109 is fixed to the lower surface of the cover plate 107;

[0034] The stirring rod 110 is rotatably mounted on the U-shaped frame 109 via a bearing;

[0035] A water turbine fan 111 is fixedly installed at the top of the stirring rod 110;

[0036] The U-shaped frame 109 has a bent pipe 112 fixedly installed on its surface by a support plate;

[0037] A water supply pipe 106 is fixedly connected to the surface of the main pipe 104. One end of the bend 112 extends through the top of the cover plate 107 and is fixedly connected to one end of the water supply pipe 106. A control valve is installed on the surface of the main pipe 104 at the position between the water supply pipe 106 and the drip irrigation capillary tube 105.

[0038] A nozzle 113 is fixedly installed at the other end of the bend 112. The nozzle 113 corresponds to the edge side of the water turbine fan 111. A filter mechanism body 108 is installed on the cover plate 107.

[0039] A solenoid valve 114 is installed on the bend 112.

[0040] In this implementation plan: When using the drip irrigation device for sorghum planting, the operator first opens the cover plate 107 by holding the handle 117 and puts the nutrients into the mixing tank 101. At the same time, the water is filtered through the filter mechanism body 108 and then discharged into the mixing tank 101.

[0041] When mixing the water and nutrients inside the mixing tank 101, the operator needs to turn the control valve (not shown in the figure) to block the main pipe 104. Next, the water pump 103 is started, and the liquid in the mixing tank 101 is extracted through the connecting pipe 102 and transported to the water delivery pipe 106. The water delivery pipe 106 then transports the liquid to the bend pipe 112. The liquid is discharged through the nozzle 113 on the bend pipe 112. The discharged liquid generates an impact force, which drives the water turbine fan 111 to rotate, thereby driving the mixing rod 110 to rotate. The rotation of the mixing rod 110 makes the nutrients and water in the mixing tank 101 fully mixed. After the mixing is completed, the operator turns the control valve again to release the blockage of the main pipe 104, so that the mixed nutrients and water can be transported to the main pipe 104 and further discharged into the drip irrigation capillary 105 for drip irrigation of sorghum.

[0042] A solenoid valve 114 is installed on the bend 112. Its function is to block the bend 112 by closing the solenoid valve 114, thereby stopping the drive of the water turbine fan 111. At this time, the stirring rod 110 will not rotate. When the solenoid valve 114 is opened, it can drive the stirring rod 110 to rotate, thereby stirring the bottom of the liquid inside the mixing tank 101 and reducing the sedimentation of nutrients.

[0043] This solution utilizes the impact force of water flow to drive stirring, eliminating the need for an additional power supply, thereby saving energy consumption and reducing operating costs. Furthermore, since there is no need for a complex motor drive system, the number of mechanical parts is reduced, making the stirring system simpler in structure, easier to install and maintain, and thus improving the effectiveness of the device.

[0044] It should be noted that the existing device {publication (announcement) number}: CN218218629U discloses a water-saving drip irrigation device under film. This patent discloses the filtration mechanism proposed in this application. The filtration mechanism body 108 in this application adopts the same technical means as the prior art. These technical means will not be described in detail here.

[0045] It should be noted that water pipe 106 can be designed as a flexible hose.

[0046] Furthermore;

[0047] In an optional embodiment, a waterproof cover 115 for waterproofing the solenoid valve 114 is fixedly installed on the lower surface of the cover plate 107.

[0048] In this embodiment: In order to protect the solenoid valve 114 from water damage, the device is also provided with a waterproof cover 115, which covers the outside of the solenoid valve 114 to extend the service life of the solenoid valve 114.

[0049] Furthermore;

[0050] In an optional embodiment, the cover plate 107 is provided with multiple sets of locking bolts 116, and the cover plate 107 is provided with threaded holes adapted to the locking bolts 116. The edge surface of the mixing tank 101 is provided with locking grooves adapted to the locking bolts 116. The locking bolts 116 pass through the threaded holes and are screwed into the locking grooves to lock the connection between the cover plate 107 and the mixing tank 101.

[0051] In this embodiment, multiple sets of locking bolts 116 are installed between the cover plate 107 and the mixing tank 101. This design can flexibly meet the disassembly and assembly requirements between the cover plate 107 and the mixing tank 101, increasing the flexibility of the structure.

[0052] The working principle and usage process of this utility model: When using this drip irrigation device for sorghum planting, the operator first opens the cover 107 by holding the handle 117 and adds nutrients into the mixing tank 101. Simultaneously, water is filtered through the filter body 108 and then discharged into the mixing tank 101. While mixing the water and nutrients inside the mixing tank 101, the operator needs to turn the control valve (not shown in the figure) to block the main pipe 104. Next, the water pump 103 is started, drawing liquid from the mixing tank 101 through the connecting pipe 102 and delivering it to the water delivery pipe 106. The water delivery pipe 106 then delivers the liquid to the bend pipe 112, where it is discharged through the nozzle 113. The discharged liquid generates an impact force, driving... The water turbine fan 111 rotates, which in turn drives the stirring rod 110 to rotate. The rotation of the stirring rod 110 ensures that the nutrients and water in the mixing tank 101 are fully mixed. After the mixing is completed, the operator turns the control valve again to release the blockage on the main pipe 104, allowing the mixed nutrients and water to be transported to the main pipe 104 and further discharged into the drip irrigation capillary 105 for drip irrigation of the sorghum. A solenoid valve 114 is installed on the bend 112. Its function is to block the bend 112 by closing the solenoid valve 114, thereby stopping the drive of the water turbine fan 111. At this time, the stirring rod 110 will not rotate. When the solenoid valve 114 is opened, it can drive the stirring rod 110 to rotate, thereby agitating the bottom of the liquid inside the mixing tank 101 and reducing the sedimentation of nutrients.

[0053] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
