Description

Technical field:

[0001] The present invention relates to the technical field of crop irrigation, in particular to a deep buried drip irrigation system. Background technology:

[0002] Currently, crops such as corn and soybeans are mostly grown in Northeast China's agricultural regions, and drip irrigation is often carried out using drip tape laid on the ground or buried underground. Drip tape is a long strip of water hose with drippers installed on it, through which water drips out. Drip tape is more efficient and water-saving than traditional irrigation methods. However, it still has many shortcomings, including the following ones:

[0003] 1. Seasonal laying and high recycling costs

[0004] Frequent disassembly and assembly of annual crops: For seasonal crops such as corn and cotton, the drip irrigation tape needs to be re-laid before sowing every year, and needs to be manually recovered after harvest, which is time-consuming and labor-intensive, and has high labor costs.

[0005] Large storage loss: If the recycled drip irrigation tape is piled up in the open air, the low temperature in winter or the bite of rodents and insects will aggravate the damage, and the leakage rate will increase by more than 30% when it is used again.

[0006] 2. Large interference in field operations and high maintenance costs

[0007] During agricultural machinery operations such as tillage, fertilization, and harvesting, tires or farm tools can easily crush the drip irrigation tape. During manual field management (such as thinning seedlings and thinning fruits), frequent trampling can cause the drip irrigation tape to shift or the interface to loosen, greatly increasing the frequency of manual maintenance of the surface drip irrigation tape.

[0008] 3. The material ages quickly and has a short service life

[0009] When surface drip irrigation tape is exposed to direct sunlight for a long time, the antioxidants (such as carbon black) in the PE material will gradually lose their effectiveness, causing the pipe wall to become hard and brittle. In open-air environments, the service life of ordinary drip irrigation tape is usually only 2-3 years.

[0010] In areas with large temperature differences between day and night (such as the northern temperate zone), drip irrigation tapes are frequently deformed due to thermal expansion and contraction, and cracks are prone to appear at the joints. In winter, at low temperatures (<-5°C), the pipe walls become brittle and are easily broken after being stepped on or crushed by machines.

[0011] The buried drip tape has the following shortcomings:

[0012] Buried drip tapes are installed parallel to the ground, within the root zone of crops. Their location and depth need to match the distribution of crop roots. For seasonal crops like corn, plowing is required after the autumn harvest. As the tractor pulls the plow forward, the plowshare cuts into the soil, and the plow walls lift and flip the soil, exchanging surface soil with deeper layers while covering surface residue and weeds. Drip tapes buried too deep cannot effectively supply water to crop roots. At an appropriate depth, plowing can damage or sever the tape, and the buried drip tape makes leaks more difficult to detect. Summary of the invention:

[0013] The technical problem to be solved by the present invention is to provide a deep buried drip irrigation system, which realizes the use of a deep buried underground water supply network in conjunction with a vertically arranged branch hose, preventing the buried branch hose from being cut or severed during crop plowing operations. There is no need for frequent laying and recycling, which reduces equipment loss and does not affect field operations. Water is directly transported to the crop root distribution area, avoiding surface evaporation.

[0014] The technical solution adopted by the present invention is: a deep buried drip irrigation system, including a water supply pipe network, a branch drip unit, and a water supply control unit;

[0015] The water supply network is buried at a certain depth below the ground;

[0016] The branch drip unit includes a branch hose, the top of the branch hose is connected to a dripper, a plurality of branch hoses are vertically connected to the water supply network, and the dripper at the top of the branch hose is buried at a certain depth below the ground;

[0017] The water supply control unit includes a water pump and a water pump electrical control box. The water pump is connected to the water storage device through a filter, and the water pump is connected to the water supply network through a pipeline. The water pump electrical control box includes a water pump control module. The water pump control module can control the working state of the water pump according to the soil moisture signal collected by the soil moisture sensor set in the soil.

[0018] Furthermore, the water supply network includes a main line and multiple branch lines, and the multiple branch lines are all connected to the main line.

[0019] Furthermore, the water supply network is buried 50-55 cm below the ground.

[0020] Furthermore, the branch hose is made of PE capillary tube or PVC composite capillary tube.

[0021] Furthermore, the dripper is an inline dripper.

[0022] Furthermore, a mesh filter is installed at the inlet of the dripper.

[0023] Furthermore, the dripper is buried 15-20 centimeters below the ground.

[0024] Furthermore, the filter is a multi-stage filter in which a centrifugal filter and a laminated filter are connected in series.

[0025] Furthermore, the water storage device adopts a non-metallic spliced liquid storage tank.

[0026] Furthermore, the water pump control module includes a controller, the soil moisture sensor monitors the soil moisture in real time and transmits the soil moisture signal to the controller, and the controller compares the actual soil moisture with the set soil moisture and outputs an instruction to control the working state of the water pump.

[0027] The beneficial effects of the present invention are:

[0028] 1. Use a deep underground water supply network in conjunction with vertically arranged branch hoses. When plowing, the plowshare cuts into the soil, and the plow wall lifts and turns the soil. During this process, the branch hoses are set vertically, and the lower part of the branch hoses is fixed to the water supply network. The upper part of the branch hoses can bend and move freely with the turned-up soil, and the branch hoses will not be cut or severed.

[0029] 2. After burying, there is no need for frequent laying and recycling. Burying underground avoids direct aging of the drip irrigation system caused by ultraviolet rays from the sun, wind and rain, freezing and thawing, and also reduces physical damage to the drip irrigation system caused by human and animal trampling and mechanical operations, thus extending the service life of the equipment.

[0030] 3. No drip irrigation tape is laid on the ground, which does not affect the operation of agricultural machinery or field operations;

[0031] 4. Water is directly transported to the crop root distribution area, avoiding surface evaporation. Description of the drawings:

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Figure 1 It is a structural schematic diagram of the present invention. Specific implementation method:

[0034] like Figure 1 As shown, a deep buried drip irrigation system includes a water supply network, a branch drip unit, and a water supply control unit;

[0035] The water supply network is buried 50-55 cm below the ground; the "deeply buried" in the patent name "deeply buried drip irrigation system" means that the depth of the pipe network is 50-55 cm.

[0036] The branch drip unit includes a branch hose 3, the top of the branch hose 3 is connected to a dripper 4, and multiple branch hoses 3 are vertically connected to the water supply network. The dripper 4 at the top of the branch hose 3 is buried 15-20 cm below the ground;

[0037] The water supply control unit includes a water pump 6 and a water pump electrical control box 7. The water pump 6 is connected to the water storage device 8 through a filter 9. The water pump 6 is connected to the water supply network through a pipeline. The water pump electrical control box 7 includes a water pump control module. The water pump control module can control the working state of the water pump 6 according to the soil moisture signal collected by the soil moisture sensor 5 set in the soil.

[0038] The water supply network includes a main line 1 and multiple branch lines 2 , and the multiple branch lines 2 are all connected to the main line 1 .

[0039] The branch hose 2 is made of PE capillary tube or PVC composite capillary tube.

[0040] The dripper 4 is an internally embedded dripper.

[0041] A mesh filter is installed at the inlet of the dripper 4.

[0042] The filter 9 is a multi-stage filter in which a centrifugal filter and a laminated filter are connected in series.

[0043] The water storage device 8 adopts a non-metallic spliced liquid storage tank, which is a patented product (patent number: ZL 202420051381.5, patent name: non-metallic spliced liquid storage tank).

[0044] The water pump control module includes a controller. The soil moisture sensor 5 monitors soil moisture in real time and transmits a soil moisture signal to the controller. The controller compares the actual soil moisture with the set soil moisture and then outputs an instruction to control the working state of the water pump 6.

[0045] When in use, a non-metallic spliced liquid storage tank is used as a water storage sedimentation tank. The non-metallic spliced liquid storage tank has a large capacity, a small footprint, high strength, good long-term acid and alkali resistance, can be quickly disassembled and assembled, and is convenient for transportation. When it is necessary to irrigate the crops, the water pump 6 is started, and water is directly dripped to the roots of the crops through the water supply network, the branch hose 3, and the dripper 4. The water drips directly into the root distribution area, avoiding the evaporation of surface moisture exposed to the air, and at the same time avoiding soil compaction caused by surface water accumulation. During the drip irrigation process, the soil moisture sensor 5 monitors the soil moisture in real time and transmits the soil moisture signal to the controller. After the actual soil moisture reaches the set soil moisture, the controller outputs an instruction to control the water pump 6 to stop supplying water.

[0046] The drip irrigation water passes through multi-stage filtration of a centrifugal filter, a laminated filter and a mesh filter at the inlet of the dripper 4 to prevent clogging of the dripper 4. The dripper 4 adopts an inlaid dripper, which is integrally formed with the branch hose 2 without joints and is not easy to fall off. The inlaid dripper has a wider flow channel, a high impurity holding capacity, and is not easily clogged by mud and sand.

[0047] For seasonal crops such as corn, plowing is required after the autumn harvest. When the tractor pulls the plow forward, the plowshare cuts into the soil, and the plow wall lifts and turns the soil upside down, exchanging the surface soil with the deep soil while burying surface residues and weeds. Traditional buried drip irrigation tapes are set parallel to the ground in the root area of crops. During the plowing process, the plowshare cutting into the soil may cut or sever the parallel drip irrigation tapes, and the drip tapes are buried underground, making it more difficult to detect leaks. The branch hose 2 of the present invention is set vertically. The branch hose 2 uses PE capillary tubes or PVC composite capillary tubes, which are flexible, can be easily bent, and have good tensile and compressive strength. The lower part of the branch hose 2 is fixed to the water supply network, and the upper part of the branch hose 2 can be bent and moved at will with the turned-up soil upside down, and the branch hose 2 will not be cut or cut.

[0048] It can be understood that the above specific description of the present invention is only used to illustrate the present invention and is not limited to the technical solutions described in the embodiments of the present invention. Those skilled in the art should understand that the present invention can still be modified or replaced by equivalents to achieve the same technical effects; as long as the use requirements are met, they are within the scope of protection of the present invention.
