Description

Technical Field

[0001] This utility model relates to the field of winter wheat planting technology, and in particular to a water and fertilizer integrated pressure distribution system for winter wheat on slopes. Background Technology

[0002] Integrated water and fertilizer management is a modern agricultural technology that organically combines the two key technologies of irrigation and fertilization. Through a controllable pipeline system and irrigation devices, water and nutrients are delivered to the soil around the roots of crops in a timely, appropriate, and accurate manner according to their needs. It achieves synchronized water and fertilizer management and efficient utilization. It is an important means to develop high-yield, high-quality, high-efficiency, ecological, and safe agriculture, as well as an important way to achieve water conservation, fertilizer reduction, and green development in agriculture.

[0003] To increase the yield of winter wheat in Xiangyang, fertigation can also be used. For example, Chinese invention patent application number CN202411602363.2, entitled "Fertilization Method for Winter Wheat", includes: diluting fertilizer into water-fertilizer through drip irrigation; the proposed fertilization method controls the type and amount of fertilizer at different times, and the use of drip irrigation increases the yield of winter wheat.

[0004] However, there are many sloping farmlands in the Xiangyang area. If a conventional fertigation system is used, the pressure will be uneven during fertilization. This results in the problem that the water pressure on the slope is lower and the crops cannot be fertilized, while the crops on the slope are thoroughly irrigated. Utility Model Content

[0005] In view of this, it is necessary to provide a pressure-distributed water and fertilizer system for winter wheat on slopes to solve the technical problem of inconsistent fertilizer application rates between crops on and off slopes due to uneven pressure when using ordinary water and fertilizer systems in the existing technology.

[0006] To achieve the above-mentioned technical objectives, the present invention provides a water and fertilizer integrated pressure distribution system for winter wheat on slopes, comprising:

[0007] The first compartment is configured for storing fertilizer;

[0008] A drip irrigation assembly includes at least two drip tapes and multiple drip tubes. The drip tapes extend laterally along the inclined surface of a slope and are connected to a first housing. At least two of the drip tapes are arranged parallel to each other and spaced apart vertically along the inclined surface of the slope. The multiple drip tubes are spaced apart along the length of the drip tapes and are all connected to the interior of the drip tapes.

[0009] The pressure regulating assembly includes a second housing, at least two detection elements, and at least two pressurizing elements. The second housing is spaced apart from the first housing. The detection elements are built into the drip irrigation tape and are used to detect the liquid pressure inside the drip irrigation tape. The pressurizing elements are connected to the drip irrigation tape and the second housing respectively and are used to replenish pressurized liquid into the drip irrigation tape.

[0010] Furthermore, the integrated water and fertilizer distribution system for winter wheat slopes also includes a first delivery pipe, which is vertically arranged along the inclined surface of the slope and connected to the interior of the first housing.

[0011] Furthermore, the drip irrigation tape includes a first tube body and multiple support parts. The interior of the first tube body is hollow and connected to multiple drip irrigation tapes. The multiple support parts are spaced apart along the length direction of the first tube body and are all connected to the circumferential inner wall of the first tube body.

[0012] Furthermore, the support portion includes a support block and at least three first support rods. The support block is disposed at the center line of the first tube body, and the at least three first support rods are evenly arranged along the circumferential direction of the support block and are all connected to the support block and the circumferential inner wall of the first tube body.

[0013] Furthermore, the pressurizing component includes a second tube and a pressurizing pump. The second tube is hollow inside and is fitted onto the first tube. The inner circumferential wall of the second tube and the outer circumferential wall of the first tube form a pressurizing channel. The pressurizing channel can be connected to the drip irrigation pipe. The inlet end of the pressurizing pump is connected to the interior of the second housing, and the outlet end is connected to the pressurizing channel.

[0014] Furthermore, the pressurizing component also includes at least three second support rods, which are evenly arranged along the circumferential outer wall of the first tube and are all connected to the circumferential outer wall of the first tube and the circumferential inner wall of the second tube.

[0015] Furthermore, the pressurizing component also includes multiple one-way valves, each one-to-one with the drip irrigation tube. The one-way valves are located on the drip irrigation tube and are connected to the interior of the drip irrigation tube and the pressurizing channel.

[0016] Furthermore, the detection element is disposed at the connection between the first tube and the delivery tube.

[0017] Furthermore, the integrated water and fertilizer distribution system for winter wheat on slopes also includes a protective sleeve, which is fitted onto the second pipe body.

[0018] Furthermore, the protective sleeve has an elastic structure.

[0019] Compared with the prior art, the beneficial effects of this utility model include: the drip irrigation tapes are all arranged to extend laterally along the inclined surface of the slope and are connected to the first box, and at least two drip irrigation tapes are arranged parallel to each other and spaced apart along the vertical direction of the inclined surface of the slope, the drip irrigation pipes are arranged spaced apart along the length direction of the drip irrigation tapes and are all connected to the interior of the drip irrigation tapes, for fertilizing crops on and off the slope, the detection element is built into the drip irrigation tape for detecting the liquid pressure in the drip irrigation tapes on and off the slope, and the pressurizing element is connected to the drip irrigation tapes and the second box respectively for replenishing pressurized liquid into the drip irrigation tapes. Compared to existing technologies, by installing detection devices in the drip irrigation tapes on and off the slope, the liquid pressure in the drip irrigation tapes on and off the slope can be detected respectively. When the pressure is lower than the preset value, the pressurizing device can pressurize the liquid in the second tank and deliver it to the drip irrigation pipe. This can achieve consistency in the amount of fertilizer applied to crops on and off the slope, and can solve the technical problem in existing technologies where uneven pressure during fertilization using ordinary water and fertilizer integration systems leads to inconsistent amounts of fertilizer applied to crops on and off the slope.

Detailed Implementation

[0026] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0027] Please see Figures 1 to 4 This utility model provides a water and fertilizer integrated pressure-regulating system for winter wheat on slopes, comprising: a first housing 100, a drip irrigation assembly 200, and a pressure regulating assembly 300. The first housing 100 is configured to store fertilizer. The drip irrigation assembly 200 includes at least two drip irrigation tapes 210 and multiple drip irrigation pipes 220. The drip irrigation tapes 210 extend laterally along the inclined surface of the slope and are connected to the first housing 100. The at least two drip irrigation tapes 210 are arranged parallel to each other and spaced apart vertically along the inclined surface of the slope. The multiple drip irrigation pipes 220... The pressure regulating components 300 are arranged at intervals along the length of the drip irrigation tape 210 and are all connected to the interior of the drip irrigation tape 210. The pressure regulating component 300 includes a second housing 310, at least two detection elements 320 and at least two pressure boosting elements 330. The second housing 310 is arranged at intervals with the first housing 100. The detection elements 320 are built into the drip irrigation tape 210 and are used to detect the liquid pressure inside the drip irrigation tape 210. The pressure boosting elements 330 are connected to the drip irrigation tape 210 and the second housing 310 respectively and are used to supplement pressurized liquid into the drip irrigation tape 210.

[0028] Compared with the prior art, this device, by setting detection elements 320 in the drip irrigation tapes 210 on the slope and at the bottom of the slope, detects the liquid pressure in the drip irrigation tapes 210 on the slope and at the bottom of the slope respectively. When the pressure is lower than the preset value, the pressurizing element 330 can pressurize the liquid in the second box 310 and deliver it to the drip irrigation pipe 220. This can achieve the consistency of the amount of fertilizer applied to crops on the slope and at the bottom of the slope, and can solve the technical problem in the prior art that the pressure is uneven when applying fertilizer in ordinary water and fertilizer integrated systems, resulting in inconsistent fertilizer application amounts to crops on the slope and at the bottom of the slope.

[0029] Furthermore, fertigation organically combines irrigation and fertilization, two key technologies. Through a controllable pipeline system and irrigation devices, water and nutrients are delivered to the crop root zone in a timely, appropriate, and accurate manner according to crop needs, achieving synchronized water and fertilizer management and efficient utilization. It is a crucial means of developing high-yield, high-quality, high-efficiency, ecological, and safe agriculture, and also an important pathway to achieving water conservation, fertilizer reduction, and green development in agriculture. Common fertigation irrigation methods for winter wheat include: Drip irrigation: suitable for most irrigated areas, with dripper spacing of 30cm. 210mm drip tape is laid along the planting row, one tape every 3-4 rows of wheat, with an average spacing ≤60cm and a laying length ≤1m. 00 meters (sand ≤ 50 meters) 12; Micro-sprinkler irrigation: micro-sprinkler with a flow rate of 80~120L / (m·h), working pressure 0.08~0.12MPa; laying spacing of 1.5~1.8 meters when the pipe diameter is 51mm, and 1.8~2.0 meters when the pipe diameter is 40mm 13; Deep buried drip irrigation: drip irrigation pipe 220 buried at a depth of 25~35cm (shallow burial in clay, not applicable to sandy soil), spacing 60cm, with matching no-till furrow sowing technology 7; Sprinkler irrigation: fixed pipeline sprinkler irrigation adopts a square combination layout (spacing is 1.0~1.1 times the nozzle range), working pressure 0.15~0.25MPa 9. This is a conventional setting known to those skilled in the art, and will not be described in detail here.

[0030] Furthermore, the drip irrigation component 200 contains multiple drip irrigation tapes 210, which are laid along the planting rows, with one tape laid for every 3 to 4 rows of wheat, an average spacing of ≤60cm, and a laying length of ≤100 meters.

[0031] In this embodiment, as Figure 1 , Figure 3 As shown, the integrated water and fertilizer distribution system for winter wheat on slopes also includes a first delivery pipe 400, which is vertically arranged along the inclined surface of the slope and connected to the interior of the first housing 100.

[0032] The first delivery pipe 400 is used to connect the first box 100 with multiple drip irrigation tapes 210.

[0033] In some embodiments, such as Figures 1 to 3 As shown, the drip irrigation tape 210 includes a first tube body 211 and a plurality of support parts 212. The first tube body 211 is hollow inside and is connected to the plurality of drip irrigation tapes 210. The plurality of support parts 212 are spaced apart along the length direction of the first tube body 211 and are all connected to the circumferential inner wall of the first tube body 211.

[0034] The drip irrigation tape 210 consists of a first tube body 211 and multiple support parts 212. The multiple support parts 212 are spaced apart along the length of the first tube body 211 to support the first tube body 211 and ensure the normal delivery of fertilizer.

[0035] Furthermore, the material of the first tube 211 here is a common and readily available material on the market. This is a conventional setting known to those skilled in the art, and will not be described in detail here.

[0036] In some embodiments, such as Figure 2 As shown, the support part 212 includes a support block 2121 and at least three first support rods 2122. The support block 2121 is located at the center line of the first tube 211, and the at least three first support rods 2122 are evenly arranged along the circumferential direction of the support block 2121 and are all connected to the support block 2121 and the circumferential inner wall of the first tube 211.

[0037] The support block 2121 is located at the center of the first tube 211, and multiple first support rods 2122 are spaced apart along the circumference of the support block 2121, thereby forming a stable support for the tube wall of the first tube 211.

[0038] In some embodiments, the support block 2121 can be a solid structure or a hollow cylindrical structure. The support block 2121 and the first support rod 2122 are made of high-strength and lightweight materials, such as polyvinyl chloride, thermoplastic elastomer, silicone rubber, polyurethane and polyolefin. These are conventional settings known to those skilled in the art and will not be described in detail here.

[0039] In some embodiments, such as Figure 4 As shown, the booster component 330 includes a second tube 331 and a booster pump 332. The interior of the second tube 331 is hollow and is sleeved on the first tube 211. The circumferential inner wall of the second tube 331 and the circumferential outer wall of the first tube 211 form a booster channel. The booster channel can be connected to the drip irrigation pipe 220. The inlet end of the booster pump 332 is connected to the interior of the second housing 310, and the outlet end is connected to the booster channel.

[0040] The second tube 331 is coaxially arranged with the first tube 211 and is sleeved on the outer wall of the first tube 211. The fertilizer in the second box 310 can be delivered to the drip irrigation pipe 220 of each drip irrigation tape 210 by pressurizing the booster pump 332.

[0041] Furthermore, the booster pump 332 here is a centrifugal pump, multistage centrifugal pump, plunger pump, or diaphragm pump. The specific selection of booster pump 332 needs to consider: 1. System required flow rate and pressure: The total head and total flow rate required by the system need to be calculated based on the irrigation area, crop water requirements, irrigation device type (dripper, sprinkler flow and pressure requirements), pipe length, pipe diameter, number of bends, fertilizer applicator type and pressure drop, and the vertical height difference from the water source to the highest point; 2. Properties of the fertilizer solution: Determine if it is corrosive and if it may contain undissolved particles. This determines the choice of pump material and pump type (diaphragm pumps are more resistant to corrosion and impurities); power supply conditions: determine whether it is single-phase or three-phase power, voltage and frequency; self-priming requirements: determine whether the pump needs to be installed above the water source surface, and how strong its self-priming capability is required; efficiency and operating costs: determine that the efficiency differences between different pump types will affect long-term electricity costs; budget: determine that the price differences between different types and brands of pumps are significant; ease of maintenance: whether the operating environment is convenient for maintenance, and what the maintenance costs and spare parts availability are; noise and vibration: important for applications near residential areas or greenhouses. These will not be elaborated further here.

[0042] Furthermore, the second housing 310 is connected to multiple second pipe bodies 331 through multiple second conveying pipes 340, which will not be described in detail here.

[0043] In some embodiments, such as Figure 2 As shown, the booster 330 also includes at least three second support rods 333. The at least three second support rods 333 are evenly arranged along the circumferential outer wall of the first tube 211 and are all connected to the circumferential outer wall of the first tube 211 and the circumferential inner wall of the second tube 331.

[0044] To enhance the overall quality and strength of the irrigation belt, the pressurizing component 330 also includes at least three second support rods 333.

[0045] Furthermore, the second support rod 333 is made of a high-strength and lightweight material, such as polyvinyl chloride, thermoplastic elastomer, silicone rubber, polyurethane and polyolefin. This is a conventional arrangement known to those skilled in the art and will not be described in detail here.

[0046] In some embodiments, such as Figure 3 As shown, the pressurizing component 330 also includes multiple one-way valves 334, which are arranged one-to-one with the drip irrigation pipes 220. The one-way valves 334 are installed on the drip irrigation pipes 220 and are connected to the interior of the drip irrigation pipes 220 and the pressurizing channel.

[0047] By setting a one-way valve 334, liquid can be prevented from entering the first pipe 211 after the booster pump 332 pressurizes, thus avoiding affecting the normal operation of the booster assembly.

[0048] Furthermore, the one-way valve 334 here is a common and readily available device on the market, and is a conventional setting known to those skilled in the art, so it will not be described in detail here.

[0049] In some embodiments, such as Figure 3 As shown, the detection element 320 is located at the connection between the first tube body 211 and the delivery tube.

[0050] To improve the accuracy of pressure detection, the detection element 320 is installed at the connection between the first pipe body 211 and the delivery pipe.

[0051] Furthermore, the detection component 320 here is a pressure sensor that is common and readily available on the market. This is a standard setting known to those skilled in the art and will not be described in detail here.

[0052] In some embodiments, such as Figure 2 As shown, the integrated water and fertilizer distribution system for winter wheat on slopes also includes a protective sleeve 500, which is fitted onto the second pipe body 331.

[0053] To prevent wear and tear during use from causing abnormal fertilization, a protective sleeve 500 is fitted onto the second pipe body 331.

[0054] In some embodiments, the protective sleeve 500 is an elastic structure.

[0055] To increase the stability of the device operation and improve the protective effect of the protective sleeve 500 on the first tube 211 and the second tube 331, the protective sleeve 500 is an elastic structure.

[0056] Furthermore, the material of the protective cover 500 is a common and readily available material on the market, such as polyethylene foam (EPE Foam), rubber (such as EPDM or Neoprene), and polyurethane foam (PUFoam). This is a conventional setting known to those skilled in the art and will not be described in detail here.

[0057] In the specific working process of this utility model, the drip irrigation tapes 210 are all arranged laterally along the inclined surface of the slope and are connected to the first housing 100. At least two drip irrigation tapes 210 are arranged parallel to each other and spaced apart along the vertical direction of the inclined surface of the slope. The drip irrigation pipes 220 are arranged spaced apart along the length direction of the drip irrigation tapes 210 and are all connected to the inside of the drip irrigation tapes 210 for fertilizing crops on and off the slope. The detection element 320 is built into the drip irrigation tape 210 for detecting the liquid pressure in the drip irrigation tapes 210 on and off the slope. The pressurizing element 330 is connected to the drip irrigation tapes 210 and the second housing 310 respectively for replenishing pressurized liquid into the drip irrigation tapes 210. Compared with existing technologies, by setting detection devices 320 in the drip irrigation tapes 210 on the slope and at the bottom of the slope, the liquid pressure in the drip irrigation tapes 210 on the slope and at the bottom of the slope can be detected respectively. When the pressure is lower than the preset value, the pressurizing device 330 can pressurize the liquid in the second box 310 and deliver it to the drip irrigation pipe 220, so as to achieve consistency in the amount of fertilizer applied to crops on the slope and at the bottom of the slope.

[0058] In use, fertilizer is fed from the first box 100 into multiple first pipes 211 through the first delivery pipe 400. The fertilizer is then delivered to the field through multiple drip irrigation pipes 220, enabling drip irrigation and fertilization of crops on or below the slope. When the detection device 320, located at the connection between the first pipe 211 and the delivery pipe, detects that the liquid pressure in the first pipe 211 is lower than a preset value, the booster pump 332 is activated and delivers the fertilizer from the second box 310 into the second pipe 331. The fertilizer then enters the drip irrigation pipe 220 through the one-way valve 334, thus compensating for the insufficient pressure on the slope.

[0059] This device, through the aforementioned structure, can solve the technical problem in the prior art where uneven pressure during fertilization using ordinary integrated water and fertilizer systems leads to inconsistent fertilization amounts for crops on and off slopes.

[0060] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
