Description

Technical Field

[0001] This invention relates to drip irrigation, and more specifically to the field of agricultural equipment technology, specifically to an automatic drip irrigation device for agricultural planting. Background Technology

[0002] In the current process of agricultural modernization, automatic drip irrigation devices have become the mainstream irrigation equipment for field crops, greenhouse horticulture and other planting scenarios because they can achieve directional water delivery and reduce evaporation loss in the field.

[0003] Due to limitations in design concepts and technical architecture, existing automatic drip irrigation devices still have significant gaps between their core functions and actual planting needs. The core connection logic of existing automatic drip irrigation devices generally adopts a unidirectional rigid structure, with a single water delivery function from the water source to the crop root zone.

[0004] Water sources generally contain impurities such as silt, algae, and microorganisms. During the transportation process through the main and branch pipes, some silt will be deposited on the inner wall of the pipes. After entering the drip irrigation pipes with the water flow, it is very easy to cause blockage due to the extremely small diameter of the drip irrigation holes. The existing system only sets up a simple filter screen at the water source inlet and lacks a pipe inner wall cleaning mechanism, which leads to the continuous accumulation of impurities and requires manual disassembly and cleaning of the drip irrigation pipes, resulting in low cleaning efficiency.

[0005] Furthermore, existing automatic drip irrigation devices employ a design with fixed orifice positions and uniform flow rates, making it impossible to adjust the irrigation method based on differences in crop type, planting density, and soil texture. Therefore, this paper proposes an automatic drip irrigation device for agricultural planting to address the aforementioned problems. Summary of the Invention

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figure 1-9The agricultural equipment of this invention belongs to drip irrigation, and provides an automatic drip irrigation device for agricultural planting, including a drip irrigation pipe 1. A support part 2 is provided on the drip irrigation pipe 1 to meet the fixing requirements of dry and hard soil. The device raises during drip irrigation and lowers as the soil softens to visually reflect the soil moisture status and help determine whether the drip irrigation is up to standard. The support part 2 includes two mounting rings 21, and a limit rod 24 is fixedly connected between the two mounting rings 21. The support part 2 also includes four support rods 22, with each pair of support rods 22 symmetrically arranged. Installed on the same mounting ring 21, the four support rods 22 are all hollow structures, and the inner walls of the four support rods 22 are slidably connected with compensating rods 23. The two mounting rings 21 are fixedly sleeved on the drip irrigation pipe 1, and the four support rods 22 are all connected to the drip irrigation pipe 1. The ends of the four compensating rods 23 are all conical structures. Before drip irrigation, the soil is dry and hard. The weight of the device causes the support rods 22 to slide down along the compensating rods 23. The conical surface of the compensating rods 23 is embedded in the soil and fixed. During drip irrigation, water flows into the support rods 22, and the water pressure pushes the compensating rods 23 to extend and embed themselves in the soil. The device gradually descends as the soil softens.

[0037] In this embodiment, the support part 2 is provided with an adjustment part 3, which flexibly adapts to the crop row spacing, solves the problem that the fixed hole position cannot adapt to the crop layout, provides a water path foundation through the switching between drip irrigation and self-cleaning modes, provides a sensor installation interface, and enables the drip irrigation device to be linked with soil monitoring. The adjustment part 3 includes a limiting sleeve 31, which is slidably connected to the limiting rod 24 and slidably sleeved on the drip irrigation pipe 1. The limiting sleeve 31 has a first water inlet hole 32 and a second water inlet hole 33. The adjustment part 3 also includes a handle 34, which is fixedly connected to the limiting sleeve 31. The outer wall of the limiting sleeve 31 is fixedly connected to a module bracket 35, which can be used to install sensor modules suitable for soil detection, such as temperature and humidity sensors, nutrient sensors, etc. There are two first water inlets 32 and two second water inlets 33. The two second water inlets 33 are symmetrically opened on the limiting sleeve 31, and the two first water inlets 32 are symmetrically opened on the limiting sleeve 31.

[0038] It is worth noting that the regulating unit 3 is equipped with a drip irrigation unit 4, which solves the problem of a single drip irrigation mode by using spot irrigation to adapt to clay and annular spraying to adapt to sandy soil. The drip irrigation unit 4 includes a drip pipe 41 and a water delivery pipe 42. One end of the drip pipe 41 is connected to the first water inlet 32, and one end of the water delivery pipe 42 is connected to the second water inlet 33. The other ends of the drip pipe 41 and the water delivery pipe 42 are connected. The drip irrigation unit 4 also includes an annular slide 43, which is fixedly connected to the inner wall of the drip pipe 41. The outer wall of the drip pipe 41 has a debris discharge hole 44, and the bottom end of the drip pipe 41 has a drip inlet 45. The water delivery pipe 42 is connected to the second water inlet 33. The center of the circle rotates 5° axially and connects to the drip pipe 41. Water flows from the larger diameter side of the water supply pipe 42 to the smaller diameter side, and sprays out the water more quickly through the angle deflection. There are two drip irrigation parts 4. The drip pipe 41 and the water supply pipe 42 in the two drip irrigation parts 4 are connected to two water inlet holes 1 32 and 2 33 respectively. The two drip irrigation parts 4 are symmetrically arranged. The drip irrigation pipe 1 has a number of drip holes 6 corresponding to the drip pipe 41. The drip pipe 41 in one drip irrigation part 4 is aligned with the drip hole 6 on one side of the drip irrigation pipe 1, and the water supply pipe 42 in the other drip irrigation part 4 is aligned with the drip hole 6 on the other side of the drip irrigation pipe 1.

[0039] It is worth noting that the drip irrigation section 4 is equipped with a self-cleaning section 5, which agitates the water flow and disrupts the conditions for impurity deposition, solving the problem of silt and fertilizer residue clogging the drip irrigation holes. No manual disassembly and cleaning is required; the impurities are discharged through centrifugal force using the impact of the water flow, achieving simultaneous irrigation and cleaning. The self-cleaning section 5 includes a rotating ring 51, with a support rod 52 connected to its inner wall. A positioning ring 53 is fixedly connected to the end of the support rod 52, and an adjusting column 54 is fitted into the positioning ring 53. A support arm 55 is fixedly connected to the end of the adjusting column 54, and a circular column 56 is fixedly connected to the end of the support arm 55. The circular column 56 is slidably connected to the inner wall of the drip pipe 41. A conical column 58 is integrally connected to the top of the circular column 56, and the drip pipe 41 and the conical column 58 are connected. A through hole 5 is provided on the conical column 58. 9. The self-cleaning part 5 also includes an arc-shaped cavity 57, which is opened on the outer wall of the circular column 56. The bottom of the circular column 56 is open. A spring 510 is elastically connected between the circular column 56 and the rotating ring 51. A blade 511 is installed around the adjusting column 54. There are two self-cleaning parts 5. The rotating rings 51 in the two self-cleaning parts 5 are rotatably connected to the inner wall of the annular slide 43 in the two drip irrigation parts 4. The conical column 58 in one self-cleaning part 5 extends into the drip hole 6 through the drip pipe 41. The conical column 58 in the other self-cleaning part 5 abuts against the outer wall of the drip irrigation pipe 1, and the arc-shaped cavity 57 on the circular column 56 is connected to the water supply pipe 42. The water flow sprayed from the water supply pipe 42 can better enter the arc-shaped cavity 57 and generate thrust to push the circular column 56 to rotate.

[0040] Working principle: After the drip irrigation pipe 1 is laid on the farmland soil, it contacts the dry soil through the compensation rod 23. At this time, due to the weight of the device, the support rod 22 will slide down along the compensation rod 23, so that the drip irrigation part 4 is close to the soil. The conical end is inserted into the soil for support and limitation. The limiting sleeve 31 can be pulled by the handle 34 to slide on the limiting rod 24, so that the conical column 58 in one drip irrigation part 4 is pushed into the drip hole 6 for insertion and limitation under the elastic force of the spring 510. The conical column 58 in the other drip irrigation part 4 will inevitably move away from the drip hole 6 on the other side and be squeezed and contracted into the drip pipe 41.

[0041] When water is introduced into the drip irrigation pipe 1, the water will flow through the through hole 59 on the conical column 58 into the circular column 56, and then into the drip pipe 41. Finally, it will drip out from the drip irrigation port 45 to irrigate the soil. The water supply pipe 42 connected thereto is in contact with the outer wall of the drip irrigation pipe 1 and creates a seal, preventing water from flowing back and overflowing.

[0042] Water from the drip irrigation section 4 on the other side enters the water supply pipe 42 through the drip hole 6 and is sprayed into the drip irrigation pipe 41. The water impacts the arc-shaped cavity 57 and causes the circular column 56 to start rotating towards the fixed side. The support arm 55 drives the adjusting column 54, and the support rod 52 drives the rotating ring 51 to rotate in the annular slide 43. The water flows from the arc-shaped cavity 57 into the drip irrigation pipe 41. The blade 511 follows the rotation to agitate the water flow and prevent water impurities from accumulating. Since the spring 510 is compressed at this point, the adjusting column 54 actually descends along the positioning ring 53 and passes through the drip irrigation port 45 to seal and block the water flow, preventing water from overflowing.

[0043] Water continuously fills the inside of the drip pipe 41, thus filling the inner walls of the circular column 56 and the conical column 58. Since the conical column 58 abuts against the outer wall of the drip irrigation pipe 1, the position of the through hole 59 is aligned with the discharge hole 44. Because the end face of the conical column 58 is smooth, it can rotate synchronously with the circular column 56. Through centrifugal force, water is thrown from the through hole 59 to the discharge hole 44, producing a certain range of annular coverage spray irrigation effect. At the same time, it can also wash away water impurities and other impurities accumulated in the through hole 59 before and after drip irrigation, achieving a self-cleaning effect.

[0044] After water is introduced into the drip irrigation pipe 1, the water enters the support rod 22 and exerts pressure on the compensation rod 23. Due to the dryness of the soil, it is relatively hard, so the water pressure gradually lifts the support rod 22, causing the compensation rod 23 to extend beyond the support rod 22 and penetrate into the soil. The entire device begins to rise automatically. When the soil moisture after drip irrigation is high and the soil gradually softens, the compensation rod 23 will gradually penetrate deeper into the soil, and the entire device begins to descend. By observing the changes in the height of the device, the current drip irrigation progress of the soil can be determined. The sliding position of the limit sleeve 31 can be freely switched to change the drip irrigation state and self-cleaning state of the two drip irrigation parts 4, thereby better covering the local soil.

[0045] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
