Abstract
Description
Technical Field
[0001] This utility model relates to an agricultural drip irrigation device with adjustable flow rate. Background Technology
[0002] Drip irrigation is a highly efficient water-saving irrigation technology that delivers water and nutrients directly to the soil near the crop roots in a slow and precise manner through a pipeline system and drippers (dripping arrows, drip tapes, etc.) installed at the ends. Its core characteristics are localized irrigation and continuous supply of water at small flow rates, minimizing evaporation and seepage losses.
[0003] The existing drip irrigation method delivers water to the surface of the soil and then infiltrates downwards. This method is particularly problematic when the ground is hot and the plants are not fully developed. As the water acts on the surface soil and slowly infiltrates downwards, some of the water evaporates upon contact with the ground. Although this method is much more water-efficient than traditional sprinkler irrigation, the water utilization rate is still insufficient.
[0004] Based on the above problems, we designed an agricultural drip irrigation device with adjustable flow rate that can directly irrigate into the soil and has a stable irrigation location. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide an agricultural drip irrigation device with adjustable flow rate that can directly irrigate into the soil and has a stable irrigation position.
[0006] To solve the above problems, the present invention adopts the following technical solution:
[0007] An adjustable flow agricultural drip irrigation device includes a water pump, a main pipe, and branch pipes. One end of the main pipe is closed, and the water pump is installed at the other end. The water pump is connected to an extended pumping pipe. A pipe joint is provided on the outer wall of the main pipe. The branch pipes are installed through the pipe joint, and a plug is installed at the end of each branch pipe. The branch pipes are flexible hoses. The device also includes a water tank unit and a water outlet unit. The water tank unit is pre-buried underground, with its upper end protruding more than 20 cm above the ground. Multiple water outlet units are provided and installed through the branch pipes. The pumping pipe is inserted into the water tank unit.
[0008] Preferably, the water tank unit includes a water tank, within which a first baffle, a second baffle, a third baffle, and a fourth baffle are movably installed. These baffles are arranged sequentially from left to right. A first chamber is formed between the first and second baffles, a second chamber between the second and third baffles, and a third chamber between the third and fourth baffles. Filter cotton is filled in the first chamber, and mixed particles are filled in the second chamber. A clean water chamber is formed to the left of the first baffle, and an inlet chamber is formed to the right of the fourth baffle. The water pump is inserted downwards into the clean water chamber. An inlet pipe and an overflow pipe communicating with the inlet chamber are provided on the outside of the water tank, and a clean water pipe communicating with the clean water chamber is provided on the outside of the water tank.
[0009] Preferably, the mixed particulate matter is a mixture of maifanite particles and activated carbon particles in a mixing ratio of 1:1.
[0010] Preferably, a tank cover is detachably installed at the upper end of the water tank.
[0011] Preferably, a ball valve is installed on the pipe joint.
[0012] Preferably, the water outlet unit includes two clamps that are fixed to each other. The two clamps are fixed to the outside of the branch pipe by bolts. A connecting pipe is provided on the outside of one of the clamps, and an insert plate is welded to the outside of the other clamp. A water outlet hole corresponding to the connecting pipe is drilled on the outer wall of the branch pipe. A first ball valve is installed on the connecting pipe. A bend is installed at the end of the first ball valve. The end of the bend faces downward. A tapered pipe is threaded to the lower part of the bend. The diameter of the tapered pipe gradually decreases downward. The lower end of the tapered pipe is inserted into the ground. Multiple water outlet holes are distributed at the lower part of the outer wall of the tapered pipe.
[0013] Preferably, the insert plate is in the shape of a "7".
[0014] The beneficial effects of this utility model are:
[0015] In this technical solution, an independently designed water outlet unit is used. The installation position of the water outlet unit can be selected according to the irrigation location, so that the water outlet position of the water outlet unit is located at the root system of the plant. By inserting the water outlet unit into the soil layer, the fixation firmness can be increased, and the irrigation water can be directly applied to the lower soil layer, further reducing water evaporation and improving water utilization. The structure of this device is simple, the cost is low, and it is suitable for widespread use. Attached Figure Description

[0026] See Figure 1 An adjustable flow agricultural drip irrigation device is shown, comprising a water pump 1, a main pipe 2, and branch pipes 3. One end of the main pipe 2 is closed, and the other end is equipped with the water pump 1. The water pump 1 is connected to an extended pumping pipe 11. A pipe joint 21 is provided on the outer wall of the main pipe 2. The branch pipes 3 are installed through the pipe joint 21. A plug 31 is installed at the end of the branch pipes 3. The branch pipes 3 are flexible. The device also includes a water tank unit 4 and a water outlet unit 5. The water tank unit 4 is buried underground, with its upper end protruding more than 20 cm above the ground. Multiple water outlet units 5 are provided and installed through the branch pipes 3. The pumping pipe 11 is inserted into the water tank unit 4.
[0027] Water is drawn from the water tank unit by a water pump and then delivered to the water supply unit through the main pipe and branch pipes. The water pressure in the main pipe is adjusted by adjusting the output power of the water pump, thereby regulating the drip irrigation flow rate.
[0028] The branch pipes use flexible hoses, which can be bent and adjusted reasonably according to the position of the plants in agricultural planting, so that the water outlet unit can output water close to the root system of the plant, so that the water can be fully applied to the root system of the plant.
[0029] Using exposed pipes makes it easier to determine the location of branch pipes, facilitates subsequent ground clearing work, and avoids accidental damage to the pipes.
[0030] The water tank unit 4 is buried and partially exposed above the ground. This pre-buried method can reduce the temperature rise of the internal water during the high temperatures of summer.
[0031] This burial method facilitates the collection of surface water by the water tank unit 4, and also facilitates the introduction of water from the irrigation canal into the water tank unit 4.
[0032] See Figure 2 As shown, the water tank unit 4 includes a water tank 41, which can be a concrete water tank or a PVC water tank. The appropriate choice can be made according to the site conditions. PVC water tanks are preferred because they are low in manufacturing cost and lightweight.
[0033] A first baffle 42, a second baffle 43, a third baffle 44, and a fourth baffle 45 are movably installed inside the water tank 41. Each of the baffles can be pulled out upwards. The first baffle 42, the second baffle 43, the third baffle 44, and the fourth baffle 45 are arranged sequentially from left to right. A first chamber is formed between the first baffle 42 and the second baffle 43, a second chamber is formed between the second baffle 43 and the third baffle 44, and a third chamber is formed between the third baffle 44 and the fourth baffle 45. Filter cotton 46 is filled in the first chamber, and mixed particles 47 are filled in the second chamber. A clean water chamber 48 is formed on the left side of the first baffle, and a water inlet chamber 49 is formed on the right side of the fourth baffle. The water pump 11 is inserted downwards into the clean water chamber 48. A water inlet pipe 410 and an overflow pipe 411 connecting the water inlet chamber 49 are provided on the outside of the water tank 41, and a clean water pipe 412 connecting the clean water chamber 48 is provided on the outside of the water tank 41.
[0034] In the above technical solution, the first, second and third baffles are used to block water, while the fourth baffle is used to perform coarse filtration of the incoming water.
[0035] Therefore, a gap is maintained between the third and fourth baffles, forming a third chamber. This third chamber is a filtration chamber. After being filtered by the fourth baffle, the mixture of particles is filtered and adsorbed, and finally filtered by the filter cotton. Only then is it extracted and pumped to each water outlet unit.
[0036] This multi-layer filtration method keeps the water sufficiently clean and prevents pipe blockage.
[0037] Water in the canal enters the water tank 41 through the inlet pipe 410. The overflow pipe is located above the ground level. When the water level reaches the overflow pipe, it is discharged to the outside of the water tank 41, especially when the water volume in the inlet pipe 410 is large and the water permeability is lower than the water intake efficiency.
[0038] The mixed particles 47 are a mixture of maifanite particles and activated carbon particles, with a mixing ratio of 1:1.
[0039] Maifan stone granules and activated carbon granules are both common filter materials that are readily available, inexpensive, and can be cleaned and reused.
[0040] See Figure 1 and Figure 2 As shown, a tank cover 4441 is detachably installed on the upper end of the water tank 41.
[0041] See Figure 3 As shown, a ball valve 221 is installed on the pipe joint 21.
[0042] A ball valve can provide overall control for branch pipelines. When the ball valve is closed, the water outlet of the corresponding branch pipeline is shut off.
[0043] See Figure 4 As shown, the water outlet unit 5 includes two clamps 51 that are fixed to each other. The two clamps 51 are fixed to the outside of the branch pipe 3 by bolts 52. A connecting pipe 53 is provided on the outside of one of the clamps 51, and a plate 54 is welded to the outside of the other clamp 51. A water outlet hole (not shown) corresponding to the connecting pipe 53 is drilled on the outer wall of the branch pipe 3. A first ball valve 55 is installed on the connecting pipe 53. A bend 56 is installed at the end of the first ball valve 55. The end of the bend 56 faces downward. A tapered pipe 57 is threaded to the lower part of the bend 56. The diameter of the tapered pipe 57 gradually decreases downward. The lower end of the tapered pipe 57 is inserted into the ground. Multiple water outlet holes 58 are distributed at the lower part of the outer wall of the tapered pipe 57.
[0044] In the above technical solution, a sealing gasket is required at the contact position between the clamp 51 and the branch pipe 3. The sealing gasket has a hole at the corresponding water outlet position. After the two clamps 51 are tightened, the sealing gasket is clamped to elastic deformation, forming a seal around the water outlet, so that the water flowing out of the water outlet can be effectively transported to the bend pipe 56 through the connecting pipe 53.
[0045] In the above technical solution, a first ball valve 55 is used for further sub-control, so that according to irrigation needs, it is also possible to adjust whether each water outlet unit 5 needs to outlet water and to adjust the water flow rate.
[0046] See Figure 4 As shown, the insert plate 54 is shaped like the number "7".
[0047] When in use, the insert plate 54 is inserted into the soil to fix the position of the branch pipe 3.
[0048] Select an appropriate length of insert plate 54 based on the looseness of the soil to be installed. Insert plate 54 is a clamp 51 that is welded for fixation.
