Description

Technical Field

[0001] The present application relates to the technical field of agricultural irrigation, and more specifically to an agricultural water-saving irrigation device. Background Art

[0002] In the field of agricultural equipment, water irrigation is an important component, and its irrigation methods include drip irrigation, sprinkler irrigation and infiltration irrigation.

[0003] Sprinkler irrigation uses sprinkler nozzles to spray water into the atmosphere, forming fine droplets that fall evenly on crops. Sprinkler irrigation improves water utilization, soil aeration, and nutrient availability, making it suitable for humid and semi-humid areas and for crops that require large-scale irrigation, such as wheat and corn.

[0004] Infiltration irrigation involves piped water deep into the soil, leveraging the soil's permeability to evenly distribute moisture to the roots of crops. This method reduces surface water waste while maintaining good soil structure. It's suitable for permeable soils like sandy and loamy soils, as well as crops that require deep irrigation, such as cotton and tobacco.

[0005] It should be noted that traditional infiltration irrigation involves pre-buried pipes in the soil to a predetermined depth. Water is then supplied to the pipes, causing them to seep out. However, the seepage depth is determined when the pipes are pre-buried, which can be insufficient for some plants with deep, well-developed root systems. Furthermore, pre-buried pipes are difficult to implement in uneven soil.

[0006] In order to irrigate plants with deep roots, the patent document (CN118923507B) discloses an agricultural irrigation device, which includes an irrigation bottom, which is inserted into the soil, and water seeps out from the side wall of the irrigation bottom to moisten the soil.

[0023] Schematic agricultural water-saving irrigation device, reference Figures 1 to 8 According to a preferred embodiment of the present invention, an agricultural water-saving irrigation device includes a support 10 and two inserts 20.

[0024] Specifically, if Figure 1 and Figure 3As shown, the support 10 includes two horizontal sections 101 and a concave arc section 102, the concave arc section 102 is located between the two horizontal sections 101, the middle section of the concave arc section 102 has a nozzle 1021 facing the central axis direction of the concave arc section 102, and the horizontal section 101 and the concave arc section 102 are both provided with a support foot 1011; in addition, each of the horizontal sections 101 is provided with an insert 20, the two inserts 20 are slidably arranged in the height direction of the support 10, the two inserts 20 are inclined at a predetermined angle in the direction facing each other, and a plurality of sliding holes 201 and an injection nozzle are arranged at intervals in the height direction of each insert 20. The water channel 202, the water injection channel 202 is connected to each of the sliding holes 201, and a telescopic tube assembly 203 is slidably arranged in each of the sliding holes 201. The telescopic tube assembly 203 is immersed in the sliding hole 201 after contraction. The extended length of the telescopic tube assembly 203 after expansion increases from top to bottom. Each of the telescopic tube assemblies 203 is provided with a seepage hole 2032. Except for the connection between the sliding hole 201 located at the bottom and the water injection channel 202, the remaining connections between the sliding holes 201 and the water injection channel 202 are all rotatably installed with valves 2011, and the valves 2011 are dynamically connected in sequence.

[0025] Furthermore, in order to realize the expansion and contraction of the expansion tube assembly 203, as shown in FIG. Figure 4 and Figure 5 As shown, each of the telescopic tube assemblies 203 includes a plurality of sleeves 2031 with gradually decreasing radial dimensions. The sleeves 2031 are coaxially arranged, and the sleeves 2031 with smaller radial dimensions can be slidably inserted into the sleeves 2031 with larger radial dimensions. The end of the sleeve 2031 with the smallest radial dimension has a spike portion, and the water seepage hole 2032 is located on the side wall of the sleeve 2031.

[0026] It should be noted that, in the present application, the number of the sliding holes 201 is four, and the valves 2011 are provided at the connection points between the three sliding holes 201 and the water injection channel 202. The valves 2011 at this time close the connection points between the sliding holes 201 and the water injection channel 202. When in use, the agricultural water-saving irrigation device is moved to the designated planting position. It should be noted that the planted plants are located in the concave arc cavity on one side of the concave arc segment 102. At this time, the two inserts 20 are respectively located on both sides of the planted plants. Subsequently, a downward force is applied to the two inserts 20, and because the inserts 20 are slidably arranged on the horizontal segment 101 in an inclined manner, the inserts 20 are inserted into the soil in an inclined manner. It should be emphasized that at this time, each of the telescopic tube assemblies 203 is immersed in the sliding hole 201, that is, referring to Figure 1At this time, the insert 20 is in the shape of a round rod as a whole. When the insert 20 is inserted into the soil, the water in the pipeline is pressurized by an external pressure pump, and then the pressurized water is sent into the water injection channel 202. Because the three valves 2011 close the three sliding holes 201 at this time, the high-pressure water can only flow into the sliding hole 201 at the bottom. It should be noted that at this time, because each sleeve 2031 of the telescopic tube assembly 203 is in a stacked and retracted state, the sleeve 2031 with the smallest radial dimension, that is, the sleeve 2031 with the spike portion, first extends out of the sliding hole 201 away from the water injection channel 202 under the action of water pressure and penetrates into the soil; then, because the valve 2011 is still not closed and as water continues to be fed in, the sleeves 2031 extend into the soil in order from the smallest radial dimension to the largest, and seep out through the seepage holes 2032. Then, after a period of time, the valve 2011 at the bottom is opened first, and the telescopic tube assembly 203 in the corresponding sliding hole 201 is sequentially extended into the soil in an ascending order of radial size; then, after a period of time, the telescopic tube assembly 203 in the upper sliding hole 201 is sequentially extended into the soil and soaks the soil at different depths. In addition, it is easy to see that, referring to Figure 2 The middle section of the soil at the top is less wetted. The tilted nozzle 1021 can humidify the soil in this section as needed. It should also be noted that when water is present on the soil surface, the soil closer to the ground becomes wetter, which explains the gradual increase in length of the telescopic tube assembly 203 from top to bottom. It should also be noted that the agricultural water-saving irrigation device is suitable for soils with low compaction, facilitating penetration of the telescopic tube assembly 203. If necessary, high-pressure gas can be used to initially propel the telescopic tube assembly 203 into position.

[0027] Furthermore, in order to realize the sequential opening of the valves 2011, as shown in FIG. Figure 6 As shown, the agricultural water-saving irrigation device slow expansion also includes a slow expansion self-adjusting component 30, and the slow expansion self-adjusting component 30 includes a rotating shaft 301 and a first transmission component 302. One end of the rotating shaft 301 is provided with a one-way blade 3011, and the other end of the rotating shaft 301 has a plurality of transmission teeth 3012 and an optical axis surface 3013. The transmission teeth 3012 are arranged on one side of the optical axis surface 3013. One end of the rotating shaft 301 with the one-way blade 3011 extends into the water injection channel 202, one end of the first transmission component 302 is dynamically connected to the transmission teeth 3012 or the optical axis surface 3013, and the other end of the first transmission component 302 is dynamically connected to one of the valves 2011.

[0028] It should be noted that when water flows toward the sliding hole 201 located at the bottom, the water impacts the one-way blade 3011 and drives the rotating shaft 301 to rotate circumferentially. It should be pointed out that only when the transmission tooth 3012 contacts the first transmission component 302, the first transmission component 302 performs a corresponding action. In other words, when the optical axis surface 3013 contacts the first transmission component 302, the first transmission component 302 does not perform an action. Then, after the rotating shaft 301 rotates by a predetermined angle, the valve 2011 performs a corresponding action, thereby expanding the telescopic tube assembly 203 in the sliding hole 201 located at the bottom, and then expanding again from the telescopic tube assembly 203 in the sliding hole 201 above.

[0029] Furthermore, in order to realize that the first transmission assembly 302 is activated only after the rotating shaft 301 rotates a predetermined number of times, the telescopic tube assembly 203 located in the upper sliding hole 201 is activated. Figure 6 As shown, the slow expansion self-adjusting component 30 also includes a delay transmission component 303, one end of the first transmission component 302 is dynamically connected to the transmission tooth 3012 or the optical axis surface 3013 through the delay transmission component 303, the delay transmission component 303 includes a fixed seat 3031 and an abutment plate 3032, the side wall of the abutment plate 3032 has a tooth groove engaged with the transmission tooth 3012, the center of the abutment plate 3032 has a threaded hole, the fixed seat 3031 includes a cutting groove 30311, a central cylinder 30312 and a torsion separation part 30313, one end of the torsion separation part 30313 has a circular hole, the central cylinder 30312 extends into the circular hole, the other end of the torsion separation part 30313 is threadedly connected to the threaded hole of the abutment plate 3032, the first transmission component 302 includes a plurality of gears 3021 that are meshed in sequence, all of which are helical gears in this application, such as Figure 7 As shown, one end of each valve 2011 has a first extension shaft 20111, a gear 3021 located at one end is fixedly connected to the first extension shaft 20111, and the gear 3021 located at the other end is spaced a predetermined distance from the abutment plate 3032.

[0030] It should be noted that, by providing the cutting groove 30311, the torsion separation portion 30313 is broken and separated from the end of the center cylinder 30312 of the fixing seat 3031 after being subjected to a predetermined torsion, and the thickness of the abutment disk 3032 is greater than the sum of the distance between the abutment disk 3032 and the gear 3021 and the thickness of the transmission tooth 3012. When the rotating shaft 301 rotates circumferentially, the transmission tooth 3012 intermittently engages with the abutment disk 3032 for each rotation of the rotating shaft 301, and drives the abutment disk 3032 to move a predetermined distance along the axial direction of the center cylinder 30312 toward the first transmission component 302. It should be noted that at this time, this meshing force is not sufficient to make the The torsion separation portion 30313 breaks, and after the rotating shaft 301 rotates a predetermined number of times, the abutment plate 3032 engages with the gear 3021 at one end of the first transmission assembly 302. At this point, when the transmission gear 3012 drives the abutment plate 3032 to rotate circumferentially, the torsion separation portion 30313 breaks and separates from the end of the fixed seat 3031 having the central cylinder 30312. At this point, the central cylinder 30312 provides rotational support for the torsion separation portion 30313, causing the torsion separation portion 30313 and the engaged gear 3021 to rotate synchronously, transmitting power to the other end of the first transmission assembly 302, causing the corresponding valve 2011 to rotate circumferentially. The provision of the delayed transmission assembly 303 provides sufficient time for the expansion of the telescopic tube assembly 203 located in the bottommost sliding hole 201.

[0031] In addition, if Figure 7 and Figure 8 As shown, the slow expansion self-adjusting component 30 also includes a plurality of second extension shafts 304 and a plurality of transmission shafts 305, one end of the second extension shaft 304 is connected to the other end of the corresponding valve 2011, the second extension shaft 304 has a circular hole cavity 3041 and a fan-shaped cavity 3042, the fan-shaped cavity 3042 is connected to the circular hole cavity 3041, one end of the transmission shaft 305 has an extension end 3051, one end of the transmission shaft 305 extends into the circular hole cavity 3041, and the extension end 3051 extends into the fan-shaped cavity 3042, and the other end of the transmission shaft 305 is dynamically connected to the corresponding valve 2011 through a gear.

[0032] It should be noted that when the valve 2011 located below rotates a predetermined angle, its corresponding second extension shaft 304 rotates circumferentially, and only after rotating a predetermined angle does the side wall of the fan-shaped cavity 3042 abut against the extension end 3051, and drive the transmission shaft 305 to rotate circumferentially, thereby realizing that the valve 2011 is unfolded in sequence.

[0033] It should also be emphasized that after each telescopic tube assembly 203 is inserted into the soil, the one-way blades 3011 continue to rotate circumferentially under the action of the water flow, causing each valve 2011 to perform cyclical rotation within a certain time period. This causes the flow rate per unit time within each sliding hole 201 to vary and change periodically, helping to maintain the soil moisture within a reasonable range. It is obvious that compared to the prior art, the present application can be placed regardless of whether the soil is flat or not, and has greater pre-embedding flexibility. Furthermore, through the insertion of the insert 20 into the soil, it can provide infiltration irrigation to different soil depths, making it suitable for irrigating plants with deep root systems. Furthermore, the provision of the telescopic tube assembly 203 allows for infiltration irrigation to a wider range within the soil, achieving the technical goal of irrigating different depths of the soil in different ranges. Furthermore, the provision of the slow expansion self-adjusting assembly 30 provides the advantage of periodic automatic adjustment of the irrigation amount.

[0034] Furthermore, in order to facilitate the placement of the first transmission component 302 and the delay transmission component 303, as shown in FIG. Figure 7 As shown, each of the inserts 20 includes a plurality of accommodating cavities 204 and a plurality of sealing plates 205. The sealing plates 205 are fixedly connected to the insert 20 and close the cavity openings of the accommodating cavities 204. A accommodating cavity 204 is provided between each of the two adjacent sliding holes 201. The first transmission assembly 302 is provided in the accommodating cavity 204 at the bottom. The fixed seat 3031 is fixedly connected to the sealing plate 205. One end of the rotating shaft 301 passes through the sealing plate 205.

[0035] It should be noted that, in order to facilitate the processing of the sliding hole 201, the water injection channel 202, the accommodating chamber 204 and the sealing plate 205, the insert 20 is preferably designed to be split. After processing the sliding hole 201, the water injection channel 202, the accommodating chamber 204 and the sealing plate 205 and placing all the components, the split insert 20 is connected into one piece by welding or bolting.

[0036] Furthermore, in order to facilitate the support of the insert 20 before use, and after the insert 20 is inserted into the soil to a predetermined depth, a resistance to prevent the insert 20 from moving up and down is applied to the insert 20, such as Figure 2 As shown, the agricultural water-saving irrigation device further includes two supporting columns 40, and each of the support legs 1011 on the horizontal section 101 is threadedly connected to a supporting column 40. It should be noted that by screwing the supporting column 40, the supporting column 40 and the insert 20 are abutted or separated.

[0037] Furthermore, if Figure 3As shown, the concave arc segment 102 has two support holes 1022, which are located at both ends of the nozzle 1021. It should be noted that the external support frame passes through the support holes 1022 and provides auxiliary support for the plant, and the insert 20 can be regarded as a reinforcement bracket to provide a limit for the external support frame.

[0038] In summary, the agricultural water-saving irrigation device based on the embodiment of the present application is explained, which provides the agricultural water-saving irrigation device with advantages such as being suitable for watering plants with deeper roots, better pre-buried flexibility, the ability to irrigate different ranges of soil at different depths, and periodic automatic adjustment of irrigation volume.

[0039] It is worth mentioning that in the embodiments of the present application, the agricultural water-saving irrigation device has a simple structure, does not involve complex manufacturing processes and expensive materials, and is highly economical. Furthermore, for manufacturers, the agricultural water-saving irrigation device provided in the present application is easy to produce and low in cost, which is more conducive to controlling production costs and further facilitating product promotion and use.

The objectives of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and explained in the embodiments.
