Description

Technical Field

[0001] The present invention relates to the technical field of agricultural equipment, and in particular to Tibetan-type automatic fertilization and irrigation equipment and an irrigation method thereof. Background Art

[0002] Fertilization and irrigation equipment is a key tool for efficient water and fertilizer delivery in modern agriculture. By combining irrigation and fertilization technology, it can achieve accurate water and fertilizer supply, improve resource utilization and crop yields. This type of equipment is widely used in field planting, greenhouses, orchards and garden maintenance. Its core functions include water-saving irrigation, precise fertilizer distribution, and automated control, etc., aiming to optimize the crop growth environment and reduce labor costs. Compared with traditional irrigation and fertilization methods, this type of equipment can save water and improve fertilizer utilization, while reducing soil compaction and environmental pollution. When using it, it is necessary to reasonably design the system according to crop needs and soil conditions, regularly maintain the pipeline to prevent blockage, and pay attention to water filtration to avoid equipment damage. Its promotion is of great significance to the sustainable development of agriculture, resource conservation, and increased production and quality.

[0003] Traditional fertilization and irrigation equipment is widely used in the field of seed and seedling cultivation. However, due to the limitations of its structure and working principle, there are often some problems that cannot be ignored. For example, traditional fertilization and irrigation equipment often adopts an extensive operation mode in farmland management, which makes it difficult to accurately respond to changes in soil moisture in a specific small area and irrigate locally. Traditional equipment usually performs large-scale uniform irrigation based on preset time or fixed water volume, such as sprinkler irrigation systems, furrow irrigation or flood irrigation facilities. Its design principle focuses on covering the entire area rather than micro-regulation. Such equipment lacks a real-time soil moisture monitoring module and cannot dynamically perceive the moisture difference between different plots. For example, when a piece of soil is insufficiently humid due to high local terrain or strong water permeability, traditional equipment will continue to irrigate in a unified mode, which may cause water accumulation in the adjacent area while the target area is still short of water; on the contrary, if a place is already in an oversaturated state due to poor drainage, the equipment will still mechanically inject water, resulting in a waste of water resources and may cause soil salinization or root rot. Summary of the invention

[0004] In view of the problem that the existing technology cannot irrigate according to the local soil moisture, a Tibetan-type automatic fertilization and irrigation equipment is proposed.

[0005] The purpose is to be able to irrigate according to the local soil moisture and to enable the equipment to respond to different humidity levels.

[0008] Furthermore, the opening and closing unit includes a retaining frame arranged at the end of the cylinder away from the shunt pipe, a guide hole opened in the middle of the retaining frame, an iron core arranged on the inner side of the guide hole, a plug arranged at the end of the iron core away from the retaining frame, a spring sleeved on the outer side of the iron core, the two ends of the spring are respectively fixedly connected to the retaining frame and the plug, and a reducing hole opened at the end of the nozzle away from the retaining frame.

[0009] Furthermore, the regulating mechanism includes a slider arranged at the bottom of the screw rod, a through hole opened at the top of the slider, the diameter of the through hole matches the diameter of the screw rod, a lifting block arranged at the top of the slider, a screw hole opened at the top of the lifting block, the thread of the screw hole matches the thread of the screw rod, a moisture-sensing hairline arranged on the side of the slider away from the shunt pipe, a horizontal tube arranged at the end of the moisture-sensing hairline away from the slider, a vertical tube arranged at the end of the horizontal tube away from the moisture-sensing hairline, the bottom of the vertical tube is fixedly connected to the nozzle, the interior of the vertical tube is communicated with the reducing hole, a cover shell arranged at the top of the outer shell, and an adjusting unit arranged at the top of the vertical tube for adjusting the flow rate.

[0010] Furthermore, a connecting ring is provided on the top of the sliding block, a ring hole is provided on the bottom of the lifting block, and a plurality of narrow holes for connecting to the outside are provided on the front of the cover shell.

[0011] Furthermore, the adjustment unit includes a knob arranged at the top of the vertical pipe, an orifice plate 1 arranged at the bottom of the knob, two movable holes symmetrically opened at the top of the orifice plate 1, an orifice plate 2 arranged at the vertical pipe near the horizontal pipe, the top of the orifice plate 2 is rotatably connected to the bottom of the orifice plate 1, two water outlet holes symmetrically opened at the top of the orifice plate 2, and a limit ring arranged at the top of the vertical pipe, the bottom of the limit ring is rotatably connected to the top of the orifice plate 1.

[0012] Furthermore, a small hole is opened at the top of the vertical pipe to accommodate the bottom of the knob, and the diameter of the movable hole is the same as the diameter of the water outlet hole.

[0013] Furthermore, the diameter of the orifice plate 1 matches the inner diameter of the vertical tube, and the diameters of the horizontal tube and the vertical tube are the same.

[0014] Another object of the present invention is to provide an irrigation method for Tibetan-type automatic fertilization and irrigation equipment, the purpose of which is to directly transport water and fertilizer to the crop roots through a pipe network system buried underground, reduce surface evaporation and runoff losses, and allow water and nutrients to reach the plant absorption area directly.

[0015] To achieve the above object, the present invention provides the following technical solution: a Tibetan-type automatic fertilization irrigation equipment irrigation method, comprising the following steps: First, before fertilization and irrigation begin, set the soil moisture threshold, which will be the trigger point for automatic irrigation. Then, water is supplied to each level of the irrigation system, transporting water from the water source to the main pipeline and distributing it to various parts of the irrigation network through branch pipelines; Finally, when the soil moisture is lower than the preset start threshold, the water outlet mechanism starts to work and irrigates. The irrigation continues until the soil moisture rises to an appropriate humidity, at which time the equipment stops irrigating.

[0016] Furthermore, after the irrigation is completed, the relevant data of this irrigation is recorded, including the date, time, duration, water consumption and fertilization conditions of the irrigation, so as to guide the subsequent crop management and irrigation plan.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the water outlet mechanism, the irrigation range can be divided into independent units. According to the moisture of the soil, the water supply function of a specific area can be started or shut down separately. This regional control mode reduces the diffusion of water to non-target plots, avoids the coexistence of dry areas and over-humid areas, reduces the waste of water resources caused by ineffective evaporation and surface runoff, optimizes the spatial allocation efficiency of water resources, and takes into account both ecological protection and agricultural production benefits.

[0018] 2. Through the control mechanism, water is automatically supplied when the ambient humidity is lower than the preset standard, and the water supply is stopped when the humidity reaches the standard. This can not only avoid the excessive drying of the land affecting crop growth, but also prevent excessive irrigation from causing waste of resources. It solves the problem of lag in manual inspections in traditional irrigation, eliminates the need for frequent on-site inspections, and reduces labor intensity.

[0019] 3. Through the set coil, the coil generates force after being energized, driving the internal mechanical structure to move, opening the closed water supply channel, and the water flows into the preset area through the pipe to achieve directional irrigation. Each coil is responsible for the water supply switch of different areas. When the humidity in the corresponding area is lower than the preset standard, the coil will enter the energized state, thereby activating the water supply function of the target area.

DETAILED DESCRIPTION

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] Example 1, reference Figure 1-Figure 12, which is the first embodiment of the present invention, provides a Tibetan-type automatic fertilization and irrigation equipment, including a water supply unit 1, a conduit 2 fixedly connected to the bottom of the water supply unit 1, a plurality of shunt pipes 3 fixedly connected to both sides of the conduit 2 in a linear array, and also including a water outlet mechanism 4 installed at the end of the shunt pipe 3 away from the conduit 2, and a regulating mechanism 5 installed on the top of the water outlet mechanism 4; the water outlet mechanism 4 is used to control the opening and closing of the water outlet component, and the regulating mechanism 5 is used to adjust the response of the equipment to different humidity; the water outlet mechanism 4 includes a nozzle 41 fixedly connected to the end of the shunt pipe 3 away from the conduit 2, and a nozzle 41 is installed inside the nozzle 41 for An opening and closing unit for controlling the opening and closing of the nozzle 41, a cylinder 42 fixedly connected to the inner wall of the nozzle 41, a coil 43 sleeved on the outer side of the cylinder 42, a bracket 44 fixedly connected to the side of the nozzle 41 close to the coil 43, the top of the bracket 44 fixedly connected to the coil 43, a connecting shaft 45 rotatably connected to the top of the coil 43, a swing arm 46 fixedly connected to the connecting shaft 45 at one end close to the coil 43, the top of the swing arm 46 rotatably connected to the coil 43, a shell 47 fixedly connected to the middle of the rotating shaft, the bottom of the shell 47 fixedly connected to the nozzle 41, and a screw rod 48 fixedly connected to the end of the rotating shaft away from the swing arm 46.

[0024] Specifically, the cylinder 42 can form a separate space inside the nozzle 41 to accommodate the winding part of the coil 43. The coil 43 is in a disconnected state under normal circumstances. After the current is connected to the coil 43 through the swing arm 46, a magnetic field will be formed to provide power for the opening and closing of the water outlet. The bracket 44 can fix the top of the coil 43 to prevent the top of the coil 43 from being displaced. The connecting shaft 45 is an insulating material and can play a role in transmitting power. The opening and closing of the circuit formed by the coil 43 can be controlled by the swing arm 46. The shell 47 can protect the parts of the equipment and provide support for the rotating shaft. The screw 48 can constrain the position of the lifting block 53. Through the set water outlet mechanism 4, the irrigation range can be divided into independent units. According to the moisture of the soil, the water supply function of a specific area can be started or closed separately. This regional control mode reduces the diffusion of moisture to non-target plots, avoids the coexistence of dry areas and over-humid areas, reduces the waste of water resources caused by ineffective evaporation and surface runoff, optimizes the spatial allocation efficiency of water resources, and takes into account both ecological protection and agricultural production benefits.

[0025] Reference Figure 4-Figure 8 A clamp-shaped terminal is provided at the top of the coil 43, and a round hole is opened at the front of the terminal through to the rear, and a prompt line is provided at the front of the housing 47.

[0026] Specifically, the coil 43 is connected to the connecting shaft 45 and the rotary arm 46 via the clamp-shaped terminal at the top, and the prompt line of the housing 47 can be used as a reference for the buried depth of the nozzle 41 .

[0027] Reference Figure 5-Figure 7The opening and closing unit includes a retaining frame 49 fixedly connected to the end of the cylinder 42 away from the shunt pipe 3, a guide hole 410 opened in the middle of the retaining frame 49, an iron core 411 slidably connected to the inner side of the guide hole 410, a plug 412 fixedly connected to the end of the iron core 411 away from the retaining frame 49, a spring 413 sleeved on the outside of the iron core 411, the two ends of the spring 413 are respectively fixedly connected to the retaining frame 49 and the plug 412, and a reducing hole 414 opened at the end of the nozzle 41 away from the retaining frame 49.

[0028] Specifically, the retaining frame 49 can constrain the maximum stroke of the plug 412, and the guide hole 410 can limit the freedom of movement of the iron core 411. Through the cooperation between the plug 412 and the reducing hole 414, the equipment irrigation can be shut off, and the equipment irrigation can be enabled by releasing the cooperation between the plug 412 and the reducing hole 414. The spring 413 can exert a force on the plug 412 so that the plug 412 maintains cooperation with the reducing hole 414 under normal conditions.

[0029] Example 2, reference Figure 8-Figure 12 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the regulating mechanism 5 includes a slider 51 slidably connected to the bottom of the screw rod 48, a through hole 52 opened at the top of the slider 51, the diameter of the through hole 52 matches the diameter of the screw rod 48, a lifting block 53 rotatably connected to the top of the slider 51, a screw hole 54 opened at the top of the lifting block 53, the thread of the screw hole 54 matches the thread of the screw rod 48, a moisture-sensing hair 55 fixedly connected to the slider 51 on the side away from the shunt pipe 3, a horizontal tube 56 fixedly connected to the end of the moisture-sensing hair 55 away from the slider 51, a vertical tube 57 fixedly connected to the end of the horizontal tube 56 away from the moisture-sensing hair 55, the bottom of the vertical tube 57 is fixedly connected to the nozzle 41, the interior of the vertical tube 57 is communicated with the variable diameter hole 414, a cover 58 fixedly connected to the top of the shell 47, and a regulating unit assembled on the top of the vertical tube 57 for regulating the flow rate.

[0030] Specifically, the slider 51 is connected to the screw rod 48 through the through hole 52 on the top and can only move along the screw rod 48. The lifting block 53 is engaged with the screw rod 48 through a thread. The lifting block 53 can be moved along the screw rod 48 by rotating it, and the lifting block 53 can drive the slider 51 to move together. When the slider 51 moves, it can drive the moisture-sensitive hair 55 and the end connected to it to move together. The length of the moisture-sensitive hair 55 is affected by the humidity of the environment. The decrease of the humidity of the environment will shorten the moisture-sensitive hair 55, and vice versa, the length of the moisture-sensitive hair 55 will increase. The vertical pipe 57 can divert a part of the water flowing through the reducing hole 414. The water flows through the vertical pipe 57 and the horizontal pipe 56 in turn and then soaks the moisture-sensitive hair 55.

[0031] Reference Figure 3 and Fig.10A connecting ring is provided at the top of the slider 51, a ring hole is provided at the bottom of the lifting block 53, and a plurality of narrow holes for connecting to the outside are provided at the front of the cover shell 58.

[0032] Specifically, the lifting block 53 can drive the slider 51 to move together when moving up and down, and the cover 58 can isolate the external soil and particulate impurities and allow water vapor to pass through the narrow holes.

[0033] Reference Figure 8-Figure 12 The regulating unit includes a knob 59 rotatably connected to the top of the vertical pipe 57, an orifice plate 510 fixedly connected to the bottom of the knob 59, two movable holes 511 symmetrically opened at the top of the orifice plate 510, an orifice plate 512 fixedly connected to the vertical pipe 57 near the horizontal pipe 56, the top of the orifice plate 512 is rotatably connected to the bottom of the orifice plate 510, two water outlet holes 513 symmetrically opened at the top of the orifice plate 512, and a limiting ring 514 fixedly connected to the top of the vertical pipe 57, the bottom of the limiting ring 514 is rotatably connected to the top of the orifice plate 510.

[0034] Specifically, the orifice plate 510 can be controlled by rotating the knob 59, and the orifice plate 512 and the limit ring 514 can cooperate to constrain the freedom of the orifice plate 510, so that the orifice plate 510 can only rotate in the original position, and the movable hole 511 and the water outlet hole 513 can allow water to flow through, and the water can only flow from the overlapping part of the movable hole 511 and the water outlet hole 513.

[0035] Reference Fig.11 and Fig.12 A small hole is opened at the top of the vertical pipe 57 to accommodate the bottom of the knob 59 , and the diameter of the moving hole 511 is the same as the diameter of the water outlet hole 513 .

[0036] Specifically, the bottom of the knob 59 penetrates into the interior of the vertical tube 57 through the small hole at the top of the vertical tube 57. The more the movable hole 511 overlaps with the water outlet hole 513, the greater the amount of water that can flow, and vice versa.

[0037] Reference Fig.11 The diameter of the orifice plate 510 matches the inner diameter of the vertical pipe 57 , and the diameter of the horizontal pipe 56 is the same as that of the vertical pipe 57 .

[0038] Specifically, the side of the orifice plate 510 fits against the inner wall of the vertical pipe 57 to block the water flow, and the rest of the structure is the same as that of the first embodiment.

[0039] In summary, the working principle of the present invention is as follows: during the process of burying the equipment, if the humidity is controlled as a reference indicator, the ground is made flush with the prompt line of the shell 47 during the burying process; if the soil humidity is used as a reference indicator, the nozzle 41 is buried to the required irrigation depth; after the equipment is buried, the water vapor from the outside enters the inside of the shell 58 through the narrow hole of the shell 58; if the humidity inside the shell 58 is greater than the outside, the water vapor inside the shell 58 will escape to the outside, so the humidity inside and outside the shell 58 will be maintained in a relatively balanced state; when the outside humidity decreases, the humidity inside the shell 58 decreases, and the humidity decrease causes the moisture-sensitive hair 55 to lose moisture and shrink, thereby shortening the length; after the moisture-sensitive hair 55 shortens, it pulls the slider 5 1. The slider 51 drives the screw rod 48 to move, the screw rod 48 drives the connecting shaft 45 to rotate, and the connecting shaft 45 drives the swing arm 46 to rotate in the direction away from the bracket 44 until the two sections of the coil 43 are connected. After the two sections of the coil 43 are connected, the current passes through the coil 43 and generates a magnetic field in the process of passing. The magnetic field attracts the iron core 411 to move in the direction close to the coil 43. The iron core 411 moves while driving the plug 412 to move. The plug 412 moves to shrink the spring 413. After the plug 412 moves, the blockage of the variable diameter hole 414 is released, so that the water flow provided by the water supply unit 1 flows out through the variable diameter hole 414. When the water flow flows through the variable diameter hole 414, a part of the water flow will be diverted into the vertical pipe 57 and the horizontal pipe 56, and then soak the wet hair 55. After the moisture-sensing hair 55 is soaked, its length increases, thereby releasing the pulling on the slider 51. Without external interference, the swing arm 46 will sag under the action of gravity, disconnecting the circuit. After the circuit is disconnected, no current flows through the coil 43, the magnetic field disappears, and the plug 412 blocks the variable diameter hole 414 under the action of the spring 413, thereby stopping irrigation. As the moisture in the environment and the cover 58 is lost, the moisture-sensing hair 55 will be dried, thereby triggering irrigation again. By turning the knob 59, the orifice plate 510 can be driven to rotate. By rotating the orifice plate 510, the overlap between the moving hole 511 and the water outlet hole 513 is adjusted. The higher the overlap between the two, the greater the water flow rate that can flow through the orifice plate 510, and the moisture-sensing hair 55 can be soaked faster, and the moving hole 511 and the water outlet hole 513 can be adjusted. The lower the overlap between 511 and the water outlet 513, the longer the water flow takes to reach the water level that immerses the moisture-sensitive hair 55. By controlling the speed at which the moisture-sensitive hair 55 is soaked, the length of the irrigation time can be adjusted. The slider 51 can be driven to move by rotating the lifting block 53, and the slider 51 drives the end of the moisture-sensitive hair 55 connected to itself to move. When the slider 51 is in a lower position, the moisture-sensitive hair 55 can drive the bottom of the rotary arm 46 to rotate at a larger angle through a smaller extension and contraction to connect the circuit. The higher the position of the slider 51 is, the greater the extension and contraction of the moisture-sensitive hair 55 is required to drive the rotary arm 46 to rotate until the circuit is connected. Therefore, by adjusting the height of the slider 51, the device can be set to trigger the irrigation action at different humidity levels.The humidity sensing hair 55 can detect the humidity of a small area and irrigate it, thereby achieving the goal of precise irrigation of arid areas.

[0040] Example 3, reference Figure 1-Figure 12 , which is the third embodiment of the present invention, provides a Tibetan-style automatic fertilization and irrigation method, comprising the following steps: S1. First, before fertilization and irrigation begin, set the soil moisture start threshold. The threshold will be the trigger point for automatic irrigation. By setting the threshold, the device can adapt to different irrigation needs.

[0041] S2, then, supplies water to each level of the irrigation system, transports water from the water source to the main pipeline, and distributes it to various parts of the irrigation network through branch pipelines. By providing water to the pipeline, crops can be irrigated in time when needed.

[0042] S3. Finally, when the soil moisture is lower than the preset start threshold, the water outlet mechanism 4 starts to work and irrigates. The irrigation continues until the soil moisture rises to an appropriate humidity. At this time, the equipment stops irrigating. Using humidity as the standard for starting and closing water supply can reduce errors in human judgment and achieve precise irrigation.

[0043] S4. After the irrigation is completed, the relevant data of this irrigation is recorded, including the date, time, duration, water consumption and fertilization conditions of the irrigation, so as to guide the subsequent crop management and irrigation plan. By recording the data, the crop cultivation process can be controlled more accurately.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
