Description

Technical Field

[0001] This application relates to the field of agricultural irrigation technology, and more specifically to an agricultural water-saving irrigation device. Background Technology

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

[0003] Sprinkler irrigation is a method of irrigation that uses nozzles to spray water into the atmosphere, forming fine droplets that are evenly distributed onto crops. Sprinkler irrigation can improve water use efficiency, improve soil aeration and nutrient status, and is suitable for humid and semi-humid areas, as well as crops that require large-scale irrigation, such as wheat and corn.

[0004] Subsurface irrigation is a method of delivering water through pipes to deeper layers of soil, utilizing the soil's permeability to evenly distribute the water to the roots of crops. Subsurface irrigation reduces surface water waste while maintaining good soil structure. It is suitable for well-drained soil types such as sandy loam and loam, as well as crops requiring deep irrigation, such as cotton and tobacco.

[0005] It should be noted that traditional drip irrigation involves pre-burying water pipes at a predetermined depth in the soil, and then supplying water to the pipes, from which water seeps out. However, the seepage depth is determined when the pipes are pre-buried, which may be insufficient for some plants with well-developed and deep root systems; in addition, it is not easy to pre-bury the pipes on uneven ground.

[0006] For irrigating plants with deep root systems, patent document (CN118923507B) discloses an agricultural irrigation device, including an irrigation bottom that is inserted into the soil. Water seeps out from the side wall of the irrigation bottom to moisten the soil. However, based on the accompanying drawings in its specification... Figure 1 As can be seen, the circumferential dimensions of the irrigation bottom are constant, and the water can only wet the adjacent soil after seepage, so the irrigation range is constant.

[0007] Therefore, there is a need for an agricultural water-saving irrigation device that is suitable for watering plants with deep root systems, has good pre-burying flexibility, can irrigate different ranges at different soil depths, and can automatically adjust the irrigation volume periodically.

[0023] Indicative agricultural water-saving irrigation device, for 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, such as 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 of the concave arc section 102. Both the horizontal sections 101 and the concave arc section 102 have support feet 1011. In addition, each horizontal section 101 is provided with an insert 20. The two inserts 20 are slidably disposed in the height direction of the support 10. Both inserts 20 are tilted at a predetermined angle in opposite directions. Each insert 20 has a plurality of sliding holes 201 and a water injection point arranged at intervals in the height direction. Channel 202, the water injection channel 202 is connected to each of the sliding holes 201, and a telescopic tube assembly 203 is slidably disposed in each of the sliding holes 201. The telescopic tube assembly 203 is submerged in the sliding hole 201 after contraction. The extension length of the telescopic tube assembly 203 increases sequentially from top to bottom after expansion. Each of the telescopic tube assemblies 203 is provided with a seepage hole 2032. Except for the connection between the bottommost sliding hole 201 and the water injection channel 202, valves 2011 are rotatably installed at the connection points between the other sliding holes 201 and the water injection channel 202. The valves 2011 are sequentially powered.

[0025] Furthermore, to achieve the telescopic extension and retraction of the telescopic tube assembly 203, as follows: 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 arranged coaxially, and the sleeves 2031 with smaller radial dimensions can slide through the sleeves 2031 with larger radial dimensions. The end of the sleeve 2031 with the smallest radial dimension has a spike. The seepage hole 2032 is located on the side wall of the sleeve 2031.

[0026] It should be noted that in this application, there are four sliding holes 201. A valve 2011 is provided at the connection between the sliding holes 201 and the water injection channel 202. The valve 2011 closes the connection between the sliding holes 201 and the water injection channel 202. In use, the agricultural water-saving irrigation device is moved to the designated planting position. It should be noted that the plant is positioned in the concave cavity on one side of the concave arc section 102. At this time, the two inserts 20 are located on both sides of the plant. Then, a downward force is applied to the two inserts 20. Because the inserts 20 are slidably mounted on the horizontal section 101, they are inserted into the soil at an angle. It should be emphasized that at this time, each telescopic tube assembly 203 is submerged in the sliding hole 201, i.e., referring to… Figure 1At this time, the insert 20 is in the shape of a round rod. After 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. Since the three valves 2011 are closed at this time, the high-pressure water can only flow into the bottommost sliding hole 201. It should be noted that at this time, since each sleeve 2031 of the telescopic tube assembly 203 is in a stacked and closed state, the sleeve 2031 with the smallest radial dimension, that is, the sleeve 2031 with the spike, first extends out of the sliding hole 201 away from the water injection channel 202 under the action of water pressure and pierces into the soil. Subsequently, since the valves 2011 are still not closed and water continues to be sent in, the sleeves 2031 extend into the soil in order of increasing radial dimension and seep out through the seepage hole 2032. Subsequently, after a period of time, the lowest valve 2011 is opened first, and the telescopic tube assembly 203 in the corresponding sliding hole 201 also extends into the soil in sequence according to its radial dimension increasing; then, after another period of time, the telescopic tube assembly 203 in the upper sliding hole 201 extends into the soil in sequence, and wets the soil at different depths. Furthermore, it is readily apparent that, referring to… Figure 2 The middle section of the soil at the top is less wetted, and the inclined nozzles 1021 can be used to humidify the middle section as needed. It should also be noted that when there is water on the soil surface, the soil closer to the ground is wetter, which is why the length of the telescopic tube assembly 203 gradually increases from top to bottom. Furthermore, the agricultural water-saving irrigation device is suitable for soils with low compaction, facilitating the insertion of the telescopic tube assembly 203 into the soil. If necessary, in the initial state, high-pressure gas can be used to propel the telescopic tube assembly 203 outwards.

[0027] Furthermore, to achieve the sequential opening of the valves 2011, as follows: Figure 6 As shown, the agricultural water-saving irrigation device further includes a self-adjusting component 30. The 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 a light axis surface 3013. The transmission teeth 3012 are arranged on one side of the light axis surface 3013. The 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 poweredly connected to the transmission teeth 3012, and the other end of the first transmission component 302 is poweredly connected to a valve 2011.

[0028] It should be noted that when the water flows to the bottommost sliding hole 201, the water impacts the one-way blade 3011 and drives the rotating shaft 301 to rotate circumferentially. It should be pointed out that the first transmission component 302 only performs a corresponding action when the transmission tooth 3012 contacts the first transmission component 302. Conversely, when the optical axis surface 3013 contacts the first transmission component 302, the first transmission component 302 does not perform an action. Thus, after the rotating shaft 301 rotates by a predetermined angle, the valve 2011 performs a corresponding action, causing the telescopic tube assembly 203 in the bottommost sliding hole 201 to unfold, and then the telescopic tube assembly 203 in the upper sliding hole 201 to unfold again.

[0029] Furthermore, to ensure that the rotating shaft 301 rotates a predetermined number of times before activating the first transmission component 302 and the telescopic tube component 203 within the upper sliding hole 201, as follows: Figure 6 As shown, the self-adjusting assembly 30 further includes a delayed transmission assembly 303. One end of the first transmission assembly 302 is poweredly connected to the transmission gear 3012 through the delayed transmission assembly 303. The delayed transmission assembly 303 includes a fixed seat 3031 and a backing plate 3032. The sidewall of the backing plate 3032 has a tooth groove that meshes with the transmission gear 3012. The center of the backing 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, into which the central cylinder 30312 extends. The other end of the torsion separation part 30313 is threadedly connected to the threaded hole of the backing plate 3032. The first transmission assembly 302 includes a plurality of sequentially meshing gears 3021, which are all helical gears in this application. Figure 7 As shown, each of the valves 2011 has a first extension shaft 20111 at one end, a gear 3021 at one end is fixedly connected to the first extension shaft 20111, and a gear 3021 at the other end is spaced at a predetermined distance from the abutment plate 3032.

[0030] It should be noted that by setting the cutting groove 30311, the torsion separation part 30313 can break off from the end of the fixed seat 3031 with the central cylinder 30312 after being subjected to a predetermined torque. The thickness of the abutment plate 3032 is greater than the sum of the distance between the abutment plate 3032 and the gear 3021 and the thickness of the transmission gear 3012. When the rotating shaft 301 rotates circumferentially, each rotation of the rotating shaft 301 causes the transmission gear 3012 to intermittently mesh with the abutment plate 3032, and drives the abutment plate 3032 to move a predetermined distance along the axial direction of the central cylinder 30312 toward the first transmission assembly 302. It should be pointed out that at this time, this meshing force is insufficient to make the abutment plate 3032 move a predetermined distance along the axial direction of the central cylinder 30312 toward the first transmission assembly 302. When the torsion separation part 30313 breaks, 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 time, when the transmission gear 3012 drives the abutment plate 3032 to rotate circumferentially, the torsion separation part 30313 breaks off from the end of the fixed seat 3031 with the central cylinder 30312. The central cylinder 30312 then provides a rotational support for the torsion separation part 30313, causing the torsion separation part 30313 and the engaged gear 3021 to rotate circumferentially synchronously, transmitting power to the other end of the first transmission assembly 302, causing the corresponding valve 2011 to rotate circumferentially. By setting the delayed transmission assembly 303, sufficient time is provided for the expansion of the telescopic tube assembly 203 located in the bottommost sliding hole 201.

[0031] In addition, such as Figure 7 and Figure 8 As shown, the self-adjusting assembly 30 further includes several second extension shafts 304 and several drive 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 cavity 3041 and a sector cavity 3042. The sector cavity 3042 communicates with the circular cavity 3041. One end of the drive shaft 305 has an extension end 3051. One end of the drive shaft 305 extends into the circular cavity 3041, and the extension end 3051 extends into the sector cavity 3042. The other end of the drive shaft 305 is poweredly connected to the corresponding valve 2011 through a gear.

[0032] It should be noted that when the valve 2011 located below rotates by a predetermined angle, its corresponding second extension shaft 304 rotates circumferentially. Only after rotating by a predetermined angle does one side wall of the fan-shaped cavity 3042 abut against the extension end 3051, thereby driving the transmission shaft 305 to rotate circumferentially, thus realizing that the valve 2011 unfolds sequentially.

[0033] It should also be emphasized that when each of the telescopic pipe assemblies 203 is inserted into the soil, since the one-way blades 3011 are still rotating circumferentially under the action of water flow, each valve 2011 rotates circumferentially in a certain time period, causing the flow rate per unit time in each sliding hole 201 to be different and to change periodically, which helps to keep the soil moisture within a reasonable range. It is evident that, compared with the prior art, this application can be placed regardless of whether the soil is flat or not, has better pre-burying flexibility, and by inserting the insert 20 into the soil, it can irrigate at different depths of the soil, which is suitable for watering plants with deep root systems. In addition, by setting the telescopic pipe assembly 203, it is possible to achieve irrigation over a larger area of ​​the soil, realizing the technical objective of watering different ranges at different depths of the soil, and by setting the slow-release self-adjusting component 30, it achieves the advantage of periodic automatic adjustment of the irrigation volume.

[0034] Furthermore, to facilitate the placement of the first transmission assembly 302 and the delayed transmission assembly 303, such as Figure 7 As shown, each of the inserts 20 includes a plurality of receiving cavities 204 and a plurality of sealing plates 205. The sealing plates 205 are fixedly connected to the inserts 20 and close the openings of the receiving cavities 204. A receiving cavity 204 is provided between each pair of adjacent sliding holes 201. The first transmission assembly 302 is provided in the receiving cavity 204 located 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 cavity 204 and the sealing plate 205, the insert 20 is preferably designed as a separate unit. After processing the sliding hole 201, the water injection channel 202, the accommodating cavity 204 and the sealing plate 205 and placing each component, the separate insert 20 is then connected as a whole by welding or bolting.

[0036] Furthermore, to facilitate the use of the insert 20 and to apply resistance to the insert 20 to prevent vertical movement after it has been inserted into the soil to a predetermined depth, such as... Figure 2 As shown, the agricultural water-saving irrigation device also includes two support columns 40, and each of the support legs 1011 on the horizontal section 101 is threadedly connected to a support column 40. It should be noted that by screwing the support column 40, the support column 40 can be made to abut or separate from the insert 20.

[0037] Furthermore, such as Figure 3As shown, the concave arc segment 102 has two support holes 1022, which are located on both sides 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, while the insert 20 can be regarded as a reinforcing bracket, providing a limit for the external support frame.

[0038] In summary, the agricultural water-saving irrigation device described in the embodiments of this application is explained, which provides advantages such as being suitable for irrigating plants with deep root systems, having good pre-buried flexibility, being able to irrigate different ranges at different soil depths, and having periodic automatic adjustment of irrigation volume.

[0039] It is worth mentioning that, in this embodiment, the agricultural water-saving irrigation device has a simple structure, does not involve complex manufacturing processes or expensive materials, and is highly economical. At the same time, for manufacturers, the agricultural water-saving irrigation device provided in this application is easy to produce and inexpensive, which is more conducive to controlling production costs and further facilitates 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, and any modifications or variations of the embodiments of the present invention may be made without departing from these principles.
