Description

Technical Field

[0001] This application relates to the field of agricultural drip irrigation equipment technology, and in particular to an environmentally friendly agricultural drip irrigation device. Background Technology

[0002] In the field of agricultural cultivation, drip irrigation technology has undergone years of development, greatly improving water resource utilization efficiency, achieving precision irrigation, and creating more favorable conditions for crop growth. With increasing environmental awareness and the acceleration of agricultural modernization, the research and development of environmentally friendly drip irrigation devices for agricultural cultivation has gradually become a focus of industry attention. These devices not only efficiently complete drip irrigation tasks but also better adapt to diverse planting environments and different planting needs. Their development is of great significance for promoting sustainable agricultural development, helping to reduce water waste, lower agricultural production costs, and thus improve crop yield and quality, meeting people's growing demand for green and environmentally friendly agricultural products.

[0003] Currently, traditional agricultural drip irrigation devices are designed in two ways: one is to pre-set the height and width of the device, which cannot be flexibly adjusted according to actual needs, and planting and irrigation are carried out in the designated space within the device. The other is to incorporate some adjustment functions, increasing the width while lowering the height of the device, thus converting the vertically distributed planting space into a horizontally distributed planting space to improve applicability.

[0004] However, in traditional devices, height and width adjustments are independent, each with its own adjustment method and structure. Users must adjust the width first before the height can be adjusted to the preset position. Because there is no effective linkage mechanism between height and width adjustments, errors can easily occur during the adjustment process, such as skipping the width adjustment step and attempting to adjust the height, thus affecting the reliability of the device. Summary of the Invention

[0005] To improve the reliability of drip irrigation devices, this application provides an environmentally friendly drip irrigation device for agricultural cultivation.

[0006] The environmentally friendly agricultural drip irrigation device provided in this application adopts the following technical solution:

[0007] An environmentally friendly drip irrigation device for agricultural cultivation includes: a liquid holding mechanism for holding irrigation liquid; a lifting mechanism, the lower end of which is located at the bottom of the liquid holding mechanism, the lifting mechanism extending vertically, and the upper end of which is used for vertical movement; a driving mechanism, the driving mechanism including a height adjusting component, two sets of width adjusting components, and two sets of first sliding grooves, the height adjusting component being connected to the upper end of the lifting mechanism, the two sets of width adjusting components being respectively located at the front and rear ends of the height adjusting component, each set of width adjusting components including two width adjusting components, the two width adjusting components in the same set being distributed on the left and right sides of the height adjusting component, the two sets of first sliding grooves being respectively located at the front and rear ends of the liquid holding mechanism, the upper end of the width adjusting component being hinged to the height adjusting component, and the lower end of the width adjusting component being slidably connected to the first sliding groove; and a drip irrigation mechanism, the drip irrigation mechanism being located on the width adjusting component, the drip irrigation mechanism being used to realize drip irrigation planting. An extension mechanism includes two sets of second slide rails, each set corresponding to a first slide rail. Each set of second slide rails includes two second slide rails, with the two second slide rails in the same set located at both ends of the first slide rail. The first end of the second slide rail is hinged to the liquid-holding mechanism. The second slide rail is used to selectively extend the length of both ends of the first slide rail. A pulling mechanism includes two sets, each set corresponding to a first slide rail. The lower end of the pulling mechanism is connected to the bottom of the liquid-holding mechanism, and the upper end of the pulling mechanism is vertically extendable and connected to the second end of the second slide rail. The upper end of the pulling mechanism is used to cooperate with the height adjustment component. When the height adjustment component moves down to a preset height, it drives the upper end of the pulling mechanism to move down. The downward movement of the pulling mechanism allows the second end of the second slide rail to rotate around the first end, thus enabling the second slide rail to cooperate with the first slide rail to achieve extension.

[0008] By adopting the above technical solution, the liquid-holding mechanism can hold irrigation liquid to provide water for drip irrigation; the lower end of the lifting mechanism is located at the bottom of the liquid-holding mechanism, and its upper end can move vertically, which can drive the height adjustment component to move up and down, realizing the adjustment of the overall height of the device for easy transportation; the drip irrigation mechanism is located on the width adjustment component, which can realize drip irrigation planting, and the height adjustment component can also adjust the setting height of the plants on the irrigation mechanism for easy observation; the height adjustment component of the driving mechanism is connected to the upper end of the lifting mechanism, and the upper end of the width adjustment component of the width adjustment group is hinged to the height adjustment component, and the lower end is slidably connected to the first slide groove. As the height adjustment component moves up and down, the lower end of the width adjustment component will be in the first slide groove. The device features an internal sliding mechanism for initial width adjustment. The first end of the second slide of the extension mechanism is hinged to the liquid-holding mechanism, allowing selective extension of both ends of the first slide, further expanding the device's usability. The lower end of the pulling mechanism connects to the bottom of the liquid-holding mechanism, while the upper end can extend vertically and connect to the second end of the second slide. When the height adjustment component moves down to the preset height, it drives the upper end of the pulling mechanism down, allowing the second end of the second slide to rotate around the first end, thus enabling the second slide to cooperate with the first slide for extension. Because the height and width adjustments are linked, the problem of the width adjustment component detaching due to the second slide not unfolding during adjustment is avoided, improving reliability.

[0009] Optionally, the liquid-holding mechanism is provided with a first mounting part, and the second slide includes a slide body, a second mounting part, a rotating shaft, and a torsion spring. The second mounting part is located at the first end of the slide body, and the rotating shaft passes through the first mounting part and the second mounting part. The second mounting part is rotatably connected to the rotating shaft, so that the slide body can rotate relative to the liquid-holding mechanism. The torsion spring is sleeved on the outer periphery of the rotating shaft, and the two ends of the torsion spring are respectively connected to the slide body and the liquid-holding mechanism, so that the slide body can be extended by cooperating with the first slide in a free state.

[0010] By adopting the above technical solution, the first mounting part of the liquid-filling mechanism cooperates with the second mounting part of the second slide, and a rotating shaft passes through it, so that the second mounting part is rotatably connected to the rotating shaft. This enables the slide body to rotate relative to the liquid-filling mechanism, providing support and a basic structure for the rotation of the slide body. The torsion spring is sleeved on the outer circumference of the rotating shaft and its two ends are respectively connected to the slide body and the liquid-filling mechanism. In the free state, the torsion spring can provide a certain elastic force, so that the slide body can maintain its extension state in cooperation with the first slide. This ensures that the second slide and the first slide can stably cooperate to extend the length when there is no external interference, avoiding the second slide from rotating arbitrarily during normal use and affecting its cooperation with the first slide, thus improving the stability and reliability of the device.

[0011] Optionally, the pulling mechanism includes an elastic telescopic member and two sets of pulling components. The elastic telescopic member is located below the height adjusting member, with its lower end connected to the bottom of the liquid holding mechanism. The upper end of the elastic telescopic member is vertically extendable. The two sets of pulling components are respectively located on the left and right sides of the elastic telescopic member. The two ends of the pulling components are respectively connected to the upper end of the elastic telescopic member and the second end of the second slide groove. When the height adjusting member moves down, causing the elastic telescopic member to move vertically down, the pulling components release the restriction on the second end of the second slide groove, causing the second slide groove to extend the first slide groove.

[0012] By adopting the above technical solution, the elastic telescopic component is located below the height adjustment component and its lower end is connected to the bottom of the liquid-holding mechanism. Its upper end can extend and retract vertically, and it can follow the height adjustment component as it moves down to the preset height. Two sets of pulling components are respectively located on the left and right sides of the elastic telescopic component, and their two ends are respectively connected to the upper end of the elastic telescopic component and the second end of the second slide. When the height adjustment component moves down, causing the elastic telescopic component to move vertically downward, the pulling components can gradually release the restriction on the second end of the second slide. Since the first end of the second slide is hinged to the liquid-holding mechanism, after the pulling components release the restriction, the second end of the second slide can rotate around the first end, thereby enabling the second slide to cooperate with the first slide to extend, which facilitates the adjustment of the overall width of the device. The linkage design can also avoid errors caused by the second slide not unfolding during adjustment, affecting the reliability of use. Furthermore, the adjustment of the overall height and width facilitates transportation, and also facilitates the adjustment of the setting height of different planting troughs for easy observation.

[0013] Optionally, the elastic telescopic member includes a pulling support, a pulling telescopic part, and a pulling elastic part. The lower end of the pulling support is connected to the bottom of the liquid holding mechanism. The pulling support has a movable cavity. The lower end of the pulling telescopic part is slidably connected to the upper end of the pulling support and passes through the movable cavity. The pulling elastic part is disposed in the movable cavity. The two ends of the pulling elastic part are respectively connected to the lower end of the pulling telescopic part and the lower end of the pulling support.

[0014] By adopting the above technical solution, the pull support provides support for the entire elastic telescopic component, and its lower end is connected to the bottom of the liquid-holding mechanism, ensuring the stability of the elastic telescopic component; the movable cavity inside the pull support provides space for the sliding of the pull telescopic component; the pull telescopic component is slidably connected to the upper end of the pull support and passes through the movable cavity, allowing it to slide up and down within the movable cavity to realize the vertical telescopic function of the elastic telescopic component; the pull elastic part is located in the movable cavity, with its two ends connected to the lower end of the pull telescopic component and the lower end of the pull support, respectively. When the pull telescopic component is subjected to external force, the pull elastic part can generate elastic deformation, playing a role in buffering and resetting, so that the elastic telescopic component can return to its initial state after being subjected to force, thereby ensuring that the pull mechanism can work normally and realizing the extension of the cooperation between the second slide groove and the first slide groove.

[0015] Optionally, the pulling assembly includes a fixed pulley and a rope. The fixed pulley is located at the lower end of the elastic telescopic member. The first end of the rope is connected to the upper end of the elastic telescopic member. The rope is wound around the fixed pulley. The second end of the rope is connected to the second end of the second groove. The minimum height of the upper end of the elastic telescopic member is higher than the height of the fixed pulley.

[0016] By adopting the above technical solution, the fixed pulley is located at the lower end of the elastic telescopic component, providing support and guidance for the rope winding and changing the direction of force on the rope. The first end of the rope connects to the upper end of the elastic telescopic component, and the second end connects to the second end of the second slide groove. When the height adjustment component moves downward, causing the elastic telescopic component to move vertically downward, the rope can transmit the movement of the elastic telescopic component to the second end of the second slide groove, releasing the pulling restriction on the second end of the second slide groove, allowing the second slide groove to rotate around the first end and cooperate with the first slide groove to achieve extension. Simultaneously, the minimum height of the upper end of the elastic telescopic component is higher than the height of the fixed pulley, ensuring that the rope can smoothly transmit force during movement. This allows the width and height adjustments of the device to be effectively linked, avoiding errors caused by the second slide groove not unfolding during adjustment, thus ensuring reliable operation.

[0017] Optionally, the height adjustment component includes a first adjustment part and a second adjustment part. The first adjustment part is connected to the upper end of the lifting mechanism and has a through groove. The second adjustment part is connected above the first adjustment part and has a mounting block on its lower side. The mounting block is detachably engaged with the through groove. There are two sets of mounting blocks and the through groove. The elastic telescopic component, the through groove, and the mounting block are arranged in pairs. The upper end of the elastic telescopic component is used to abut against and push the mounting block. When the thrust of the elastic telescopic component on the mounting block is less than the connection force between the first adjustment part and the second adjustment part, the mounting block pushes the upper end of the elastic telescopic component downward. When the thrust of the elastic telescopic component on the mounting block is greater than the connection force between the first adjustment part and the second adjustment part, the mounting block disengages from the through groove.

[0018] By adopting the above technical solution, the first adjusting part is connected to the upper end of the lifting mechanism and can move with the vertical movement of the lifting mechanism, providing a basis for height adjustment. The through groove on the first adjusting part is detachably matched with the mounting block on the lower side of the second adjusting part, and two sets of mounting blocks and through grooves are provided, corresponding to the elastic telescopic members in pairs. This corresponding arrangement allows for effective cooperation between the elastic telescopic members and the height adjusting parts. When the thrust of the elastic telescopic member on the mounting block is less than the connecting force between the first and second adjusting parts, the mounting block pushes the upper end of the elastic telescopic member downward, realizing the retraction of the elastic telescopic member, thereby adjusting the height of the device as needed; when the thrust of the elastic telescopic member on the mounting block is greater than the connecting force between the first and second adjusting parts, the mounting block disengages from the through groove.

[0019] Optionally, it also includes a control mechanism, which is disposed on the liquid holding mechanism. An electromagnet is provided at the first end of the second slide and the end of the first slide, and the electromagnet is electrically connected to the control mechanism.

[0020] By adopting the above technical solution, the control mechanism is set on the liquid-filling mechanism, which allows for centralized control and management of the entire device's operation. Electromagnets are installed at both the first end of the second chute and the end of the first chute, and these electromagnets are electrically connected to the control mechanism, which can control the on / off state of the electromagnets. When the electromagnets are energized, an attraction force is generated between the second chute and the first chute, enhancing the stability of their connection and ensuring that the extension mechanism can stably extend the length of both ends of the first chute. When the electromagnets are de-energized, the attraction force is released, allowing the second chute to rotate around its first end, thus adjusting the length of the first chute and facilitating flexible adjustment of the device's width according to actual needs. Furthermore, after the second chute is extended in conjunction with the first chute, the height of the first adjustment part can continue to decrease, allowing the lower end of the width adjustment component to continue moving towards the end of the first chute. Since the second chute is magnetically attracted to the first chute, it will not move further, ensuring that the second chute reliably supports and guides the lower end of the width adjustment component.

[0021] Optionally, the height adjustment component includes a guide portion and two sets of limiting portions. The first adjustment portion is provided with a first through hole, and the second adjustment portion is provided with a second through hole. The guide portion slides through the first through hole and the second through hole, and the two sets of limiting portions are respectively provided at the upper and lower ends of the guide portion.

[0022] By adopting the above technical solution, the height adjustment component is provided with a guide part, which slides through the first through hole of the first adjustment part and the second through hole of the second adjustment part. This guide part can provide guidance for the relative movement of the first adjustment part and the second adjustment part, making the adjustment process of the height adjustment component more stable and smooth. Two sets of limiting parts are provided at the upper and lower ends of the guide part to prevent the first adjustment part and the second adjustment part from detaching from the guide part during movement, ensuring the stability and reliability of the overall structure of the height adjustment component, and thus ensuring the normal operation of the height adjustment function of the entire environmentally friendly agricultural drip irrigation device.

[0023] Optionally, the drip irrigation mechanism includes a water pump and two sets of drip irrigation components. The two sets of drip irrigation components are respectively disposed on both sides of the height adjustment component. Each drip irrigation component includes a connecting hose, a drip irrigation tape, and a planting trough. The connecting hose, the drip irrigation tape, and the planting trough are arranged in pairs. The two ends of the drip irrigation tape are respectively connected to the width adjustment components on the same side at the front and rear ends. The planting trough is suspended on the drip irrigation tape. The water pump inlet is connected to the liquid holding mechanism. The two ends of the connecting hose are respectively connected to the water pump outlet and the drip irrigation tape inlet. The water pump outlet is located on the side of the first chute away from the liquid holding mechanism.

[0024] By adopting the above technical solution, the water pump can extract irrigation liquid from the liquid-holding mechanism and deliver it to the drip irrigation tape via a connecting hose. The drip irrigation tape is connected to width-adjusting components on the same side at both ends, allowing its position to be adjusted as the width-adjusting components move to adapt to different planting layouts. The planting trough is suspended on the drip irrigation tape, preventing it from tipping over during layout adjustments. This ensures that the irrigation liquid is evenly dripped onto the crop plants in the planting trough, achieving precise drip irrigation and effectively improving irrigation efficiency and water resource utilization. Furthermore, because the connecting hose connects the water pump outlet and the drip irrigation tape inlet, and the water pump outlet is located on the side of the first chute furthest from the liquid-holding mechanism, this layout makes the irrigation liquid delivery path more rational, reducing pipe bends and tangles, and facilitating the installation, maintenance, and use of the device.

[0025] Optionally, a movable component is provided on the side of the first chute away from the liquid-holding mechanism. The movable component includes a bearing groove, a tension spring, a fixed block, a push wedge, a return spring, and a movable member. The bearing groove is located on the side of the first chute away from the liquid-holding mechanism. The movable member is slidably disposed within the bearing groove. The two ends of the tension spring are respectively connected to the lower end of the movable member and the bottom of the bearing groove. The fixed block is connected to the bottom of the bearing groove. The push wedge is located on one side of the fixed block and slidably connected to the bearing groove. The inclined surface of the push wedge is slidably engaged with the movable member. The two ends of the return spring are respectively connected to the fixed block and the first end of the push wedge with a smaller longitudinal cross-sectional area. The second end of the push wedge with a larger longitudinal cross-sectional area is used to engage with the first end of the second chute. When the second chute engages with the first chute, the second chute pushes the push wedge to move closer to the fixed block, pushing the movable member upward. The movable member is used to push the connecting hose to prevent the connecting hose from getting stuck in the first chute.

[0026] By adopting the above technical solution, a movable component is set on the side of the first chute away from the liquid-holding mechanism. The bearing groove provides installation space and range of motion for the movable part, the push wedge, and other components. The two ends of the tension spring are respectively connected to the lower end of the movable part and the bottom of the bearing groove, which can provide a pulling force to reset the movable part after it moves up. The fixed block is connected to the bottom of the bearing groove, which provides support and limit for the sliding of the push wedge. The push wedge is located on one side of the fixed block and is slidably connected to the bearing groove. Its inclined surface is slidably engaged with the movable part. When the second chute engages with the first chute, the second chute pushes the push wedge to move closer to the fixed block, and then uses the inclined surface to convert the horizontal thrust into the upward moving force of the movable part. The two ends of the reset spring are respectively connected to the fixed block and the first end of the push wedge with the smaller longitudinal cross-sectional area, which can reset the push wedge after it moves. The movable part slides in the bearing groove. When the second chute pushes the push wedge to move the movable part up, the movable part can push the connecting hose to prevent the connecting hose from getting stuck on the first chute and affecting the sliding reliability of the width adjustment component.

[0044] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4This application will be further described in detail below. In this embodiment, unless otherwise specified, "connection", "linking", and "fixing" are interpreted broadly, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection, and interaction between two components, etc., and can be understood according to the specific circumstances.

[0045] In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, in the description of this embodiment, terms such as "above," "below," "left," and "right," etc., are based on the orientation or positional relationships shown in the accompanying drawings and are used only for ease of description and simplification of operation. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Unless otherwise stated, directional terms such as "inner" and "outer" used in this application refer to the outline of the corresponding component itself.

[0046] like Figure 1 , Figure 2 and Figure 3 As shown in the embodiment of this application, an environmentally friendly agricultural drip irrigation device (hereinafter referred to as the "device") is disclosed. The device includes a liquid-filling mechanism 1, a lifting mechanism 2, a driving mechanism 3, a drip irrigation mechanism 4, an extension mechanism 5, and a pulling mechanism 6. By coordinating multiple mechanisms such as liquid-filling, lifting, driving, and drip irrigation, the device achieves height and width linkage adjustment for drip irrigation. This makes the overall height of the device adjustable, facilitating transportation and adjustment of the planting trough 423 height. Furthermore, the linkage between height and width adjustment improves the reliability of use.

[0047] like Figure 1 , Figure 2 and Figure 3As shown, the lower end of the lifting mechanism 2 is located at the bottom of the liquid holding mechanism 1 and extends vertically. Its upper end can move vertically, driving the height adjustment component 31 of the mechanism 3 to connect to the upper end of the lifting mechanism 2. Two sets of width adjustment components are respectively located at the front and rear ends of the height adjustment component 31. The upper end of the width adjustment component 32 is hinged to the height adjustment component 31, and the lower end is slidably connected to the first slide groove 33 on the liquid holding mechanism 1. The drip irrigation mechanism 4 is located on the width adjustment component 32. The second slide groove 51 of the extension mechanism 5 is correspondingly set with the first slide groove 33. The first end of the second slide groove 51 is hinged or rotatably connected to the liquid holding mechanism 1. The lower end of the pulling mechanism 6 is connected to the bottom of the liquid holding mechanism 1, and the upper end can extend vertically and connect to the second end of the second slide groove 51. When the height adjustment component 31 moves down to the preset height, it drives the upper end of the pulling mechanism 6 to move down, so that the second slide groove 51 and the first slide groove 33 cooperate to achieve extension, achieving the effect of adjusting the overall height and width of the device, and linking the height and width adjustment to avoid adjustment errors and improve the reliability of use. The lifting mechanism 2 drives the height adjustment component 31 to move, thereby causing the width adjustment component 32 to slide within the first slide groove 33 to achieve width adjustment. At the same time, the height adjustment component 31 moves down, triggering the pulling mechanism 6 to extend the first slide groove 33 by the second slide groove 51, ensuring reliable and continuous support for the lower end of the slide groove of the width adjustment component 32. Throughout the process, the various mechanisms cooperate with each other to achieve the linkage of height and width adjustment.

[0048] like Figure 1 , Figure 2 and Figure 3 As shown, the liquid holding mechanism 1 is used to hold irrigation liquid, and it can be a container with a certain volume. The liquid holding mechanism 1 is provided with a first mounting part 11 for mounting a second chute 51. The liquid holding mechanism 1 is also provided with a partition 12, which divides the liquid holding mechanism 1 into a clean area near the water pump 41 on the liquid holding mechanism 1 and a feeding area away from the water pump 41. The feeding area is used to add water, culture medium or other liquids to form irrigation liquid; the clean area is used to store the filtered irrigation liquid to reduce the risk of blockage of subsequent structures.

[0049] The lifting mechanism 2 can be a hydraulic lifting rod or an electric telescopic rod, etc., which can achieve telescopic structure. Its lower end is a fixed end, which is fixed to the bottom of the liquid holding mechanism 1, and the upper telescopic end can rise or fall, driving the height adjustment component 31 to move up and down.

[0050] like Figure 1 , Figure 2 and Figure 3As shown, the height adjustment component 31 of the driving mechanism 3 includes a first adjustment part 311 and a second adjustment part 312. The first adjustment part 311 is connected to the upper end of the lifting mechanism 2 and has a through groove 3111. The second adjustment part 312 is detachably connected to the upper part of the first adjustment part 311, and a mounting block 3121 is provided on the lower side of the second adjustment part 312. The mounting block 3121 is detachably engaged with the through groove 3111, and both the mounting block 3121 and the through groove 3111 have two sets. The first adjustment part 311 and the second adjustment part 312 can be magnetically connected, such as by a magnet. The height adjustment component 31 also includes a guide portion 313 and two sets of limiting portions 314. The first adjustment portion 311 has a first through hole 3112, and the second adjustment portion 312 has a second through hole (not shown in the figure). The guide portion 313 slides through the first through hole 3112 and the second through hole. The two sets of limiting portions 314 are respectively provided at the upper and lower ends of the guide portion 313. The guide portion 313 can ensure the stability of the height adjustment component 31's vertical movement, while the limiting portions 314 prevent the height adjustment component 31 from disengaging from the guide portion 313. Each width adjustment group includes two width adjustment components 32, and the two width adjustment components 32 in the same group are distributed on the left and right sides of the height adjustment component 31. The width adjustment component 32 can be a metal rod or a plastic rod, with its upper end hinged to the height adjustment component 31 via a hinge shaft, and its lower end slidably connected to the first slide groove 33 via a hinged slider. The first slide groove 33 is respectively provided at the front and rear ends of the liquid holding mechanism 1. The first slide groove 33 can be a T-shaped groove to ensure that the slider hinged at the lower end of the width adjusting member 32 can slide reliably and smoothly in it.

[0051] like Figure 1 , Figure 2 and Figure 3As shown, the drip irrigation mechanism 4 includes a water pump 41 and two sets of drip irrigation components 42, which are respectively located on both sides of the height adjustment component 31. Each drip irrigation component 42 includes a connecting hose 421, a drip irrigation tape 422, and a planting trough 423, arranged in pairs. The two ends of the drip irrigation tape 422 are respectively connected to the width adjustment components 32 on the same side at both ends. The planting trough 423 is rotatably suspended on the drip irrigation tape 422. Multiple drip irrigation components 42 can be distributed and spaced apart on the same width adjustment component 32. The water pump 41 is located on the liquid collection mechanism 1. The inlet of the water pump 41 is connected to the clean area within the liquid collection mechanism 1, and the outlet of the water pump 41 is connected to multiple connecting hoses 421 through a split pipe, thereby connecting the two ends of the connecting hoses 421 to the outlet of the water pump 41 and the inlet of the drip irrigation tape 422, respectively. The drip irrigation tape 422 is a tubular or strip structure with multiple water outlets and has sufficient rigidity. The specific type can be selected as needed to suspend the planting trough 423. The outlet of the water pump 41 is located on the side of the first chute 33 away from the liquid holding mechanism 1. The water pump 41 can be a centrifugal pump or a diaphragm pump, etc. When the water pump 41 is working, it delivers the irrigation liquid in the clean area of ​​the liquid holding mechanism 1 to the drip irrigation tape 422 through the connecting hose 421, and then drips the irrigation liquid from the drip irrigation tape 422 onto the crop plants in the planting trough 423.

[0052] The second slide group of the extension mechanism 5 is correspondingly arranged with the first slide group 33. Each second slide group includes two second slides 51, and the two second slides 51 in the same group are respectively located at both ends of the first slide group 33. The second slide group 51 includes a slide body 511, a second mounting part 512, a rotating shaft 513, and a torsion spring 514. The second mounting part 512 is located at the first end of the slide body 511. The rotating shaft 513 is connected to the first mounting part 11 and passes through the first mounting part 11 and the second mounting part 512. The second mounting part 512 is rotatably connected to the rotating shaft 513, so that the slide body 511 can rotate relative to the liquid holding mechanism 1. The torsion spring 514 is sleeved on the outer circumference of the rotating shaft 513. The two ends of the torsion spring 514 are respectively connected to the slide body 511 and the liquid holding mechanism 1, so that the slide body 511 can cooperate with the first slide group 33 in a free state to achieve the extension in the length direction.

[0053] like Figure 1 , Figure 3 and Figure 4As shown, the pulling mechanism 6 includes an elastic telescopic member 61 and two sets of pulling components 62. The elastic telescopic member 61 is located below the height adjusting member 31. The lower end of the elastic telescopic member 61 is connected to the bottom of the liquid holding mechanism 1, and the upper end of the elastic telescopic member 61 can extend and retract vertically and corresponds to the mounting block 3121. The elastic telescopic member 61 includes a pulling support part 611, a pulling telescopic part 612, and a pulling elastic part (not shown in the figure). The lower end of the pulling support part 611 is connected to the bottom of the liquid holding mechanism 1, and a movable cavity is provided inside the pulling support part 611. The lower end of the pulling telescopic part 612 is slidably connected to the upper end of the pulling support part 611 and passes through the movable cavity. The pulling elastic part is located inside the movable cavity, and the two ends of the pulling elastic part are respectively connected to the lower end of the pulling telescopic part 612 and the lower end of the pulling support part 611.

[0054] like Figure 1 , Figure 3 and Figure 4 As shown, the pulling assembly 62 includes a fixed pulley 621 and a flexible rope 622. The fixed pulley 621 is located at the lower end of the elastic telescopic member 61. The first end of the rope 622 is connected to the upper end of the elastic telescopic member 61. The rope 622 is wound around the fixed pulley 621. The second end of the rope 622 is connected to the second end of the second groove 51. The minimum height of the upper end of the elastic telescopic member 61 is higher than the height of the fixed pulley 621. The elastic telescopic member 61, the through groove 3111, and the mounting block 3121 are arranged in pairs. The upper end of the elastic telescopic member 61 is used to abut against and push the mounting block 3121. The upper end of the elastic telescopic member 61 can pass through the through groove 3111. When the pushing force of the elastic telescopic member 61 on the mounting block 3121 is less than the connecting force between the first adjusting part 311 and the second adjusting part 312, the mounting block 3121 pushes the upper end of the elastic telescopic member 61 downward. When the pushing force of the elastic telescopic member 61 on the mounting block 3121 is greater than the connecting force between the first adjusting part 311 and the second adjusting part 312, the mounting block 3121 disengages from the through groove 3111. When the height adjusting member 31 moves downward, causing the elastic telescopic member 61 to move vertically downward, the pulling component 62 releases the restriction on the second end of the second slide groove 51, allowing the second slide groove 51 to extend the first slide groove 33 under the action of the torsion spring 514. After the mounting block 3121 is dislodged from the through groove 3111, the second adjusting part 312 stops moving downwards, while the first adjusting part 311 can continue to move downwards. After the first adjusting part 311 moves upwards from below the second adjusting part 312, at a set distance from the second adjusting part 312, the two can be re-adhesive and connected. Subsequently, as the second adjusting part 312 rises, the pulling mechanism 6 gradually resets, thereby pulling the second end of the second slide groove 51.

[0055] Specifically, the pulling elastic part can be a spring, and the specific parameters such as the stiffness and elasticity of the spring can be set as needed; the height of the rope 622 inside the liquid holding mechanism 1 is lower than the height of the rope 622 outside the liquid holding mechanism 1 to reduce the risk of interference with the drip irrigation mechanism 4. The side wall of the liquid holding mechanism 1 is provided with a Z-shaped channel for passing the rope 622 through, so that the height of the rope 622 is different on the inside and outside of the liquid holding mechanism 1; the bends of the channel are all provided with rounded corner transitions to improve the smoothness of the movement of the rope 622.

[0056] like Figure 1 , Figure 3 and Figure 4 As shown, the device also includes a control mechanism 7 and a filter 8. The control mechanism 7 is located on the liquid-holding mechanism 1. Electromagnets 347 are provided at the first end of the second slide 51 and the end of the first slide 33. The electromagnets 347 are electrically connected to the control mechanism 7, which controls the on / off state of the electromagnets 347, thereby enabling the connection and separation of the second slide 51 and the first slide 33. The control mechanism 7 is also electrically connected to other necessary mechanisms such as the lifting mechanism 2, so that the electromagnets 347 are energized and attracted after the second slide 51 and the first slide 33 are engaged, preventing accidental reset when the height adjustment component 31 continues to descend, ensuring reliable operation. After the electromagnets 347 are energized, they are de-energized after the first adjustment part 311 and the second adjustment part 312 are reconnected. It is understood that the device can be equipped with necessary sensors to facilitate position detection. For example, a distance sensor can be installed on the elastic telescopic member 61 to detect the distance between the upper and lower ends of the elastic telescopic member 61, and electrically connected to the control mechanism 7 to determine the on / off switching of the electromagnet 347, energizing it when the upper end of the elastic telescopic member 61 descends to its lowest position. Distance sensors can also be installed on the first slide rail 33 and the second slide rail 51 to energize it when the upper end of the elastic telescopic member 61 descends and the first slide rail 33 and the second slide rail 51 extend in coordination. Furthermore, distance sensors can be installed on the first adjusting part 311 and the second adjusting part 312 to de-energize the electromagnet 347 when the upper end of the lifting mechanism 2 rises and the distance between the first adjusting part 311 and the second adjusting part 312 reaches or falls below a preset value. The specific control of the on / off switching of the electromagnet 347 can be set as needed, or it can be switched by manual observation, as long as the required function is achieved. The magnitude of the magnetic attraction force of the electromagnet 347 can be determined according to the actual situation. The filter 8 is mounted on the liquid-holding mechanism 1. The inlet of the filter 8 is connected to the feeding area, and the outlet of the filter 8 is connected to the cleaning area. It can filter impurities in the irrigation liquid and ensure that the drip irrigation tape 422 is not blocked. The control mechanism 7 can be a PLC, and the filter 8 can be a suitable existing structure.

[0057] like Figure 1 , Figure 3 and Figure 4As shown, a movable component 34 is provided on the side of the first slide groove 33 away from the liquid-holding mechanism 1. The movable component 34 includes a bearing groove 341, a tension spring 342, a fixing block 343, a pushing wedge 344, a return spring 345, and a movable member 346. The bearing groove 341 is located on the side of the first slide groove 33 away from the liquid-holding mechanism 1. The movable member 346 is slidably disposed within the bearing groove 341. The two ends of the tension spring 342 are respectively connected to the lower end of the movable member 346 and the bottom of the bearing groove 341. The fixing block 343 is connected to the bottom of the bearing groove 341. The pushing wedge 344 is located on one side of the fixing block 343 and is slidably connected to the bearing groove 341. Furthermore, the pushing wedge 344 is prevented from completely dislodging from the bearing groove 341 by a limiting mechanism. The inclined surface of the push wedge 344 slides in engagement with the movable part 346. The two ends of the return spring 345 are respectively connected to the fixed block 343 and the first end of the push wedge 344 with the smaller longitudinal cross-sectional area. The second end of the push wedge 344 with the larger longitudinal cross-sectional area engages with the first end of the second slide groove 51. When the second slide groove 51 engages with the first slide groove 33, the second slide groove 51 pushes the push wedge 344 towards the fixed block 343, compressing the return spring 345 and pushing the movable part 346 upwards. The movable part 346 pushes the connecting hose 421 to prevent the connecting hose 421 from getting stuck in the first slide groove 33, thus affecting reliability. The movement of the movable part 346 provides a driving force for the connecting hose 421, allowing for fine-tuning and movement of the connecting hose 421 through external force, reducing the problem of the connecting hose 421 getting stuck in the first slide groove 33 and affecting the sliding of the width adjustment part 32. The specific parameters such as elasticity, stiffness, and length of the tension spring 342 and the return spring 345 can be determined as needed to achieve the required function. Furthermore, the relationship between the specific parameters of each spring in the device can be specifically determined according to the usage requirements to ensure the normal functioning. The installation position of the electromagnet 347 is not limited. For example, the electromagnet on the first slide groove 33 can be installed on the push wedge block 344 or at the end of the first slide groove 33.

[0058] Understandably, the device also includes necessary structures for connection, support, drive, positioning, limiting, sealing, position detection and control, so that the device can operate normally; the shape, size, material and number of each part of the device can be determined as needed, as long as the corresponding functions can be achieved.

[0059] The implementation principle of this embodiment is as follows: This environmentally friendly agricultural drip irrigation device achieves adjustable overall height and width through the coordinated operation of various mechanisms, with the height and width adjustments linked. During transportation, the device height can be adjusted to lower it for easier transport. During use, the device height can be adjusted as needed to facilitate observation of crop growth in different planting troughs 423. Simultaneously, the linkage between height and width adjustments prevents adjustment errors and improves the reliability of the device.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
