Description

Technical Field

[0001] This invention relates to the field of agricultural irrigation technology, and in particular to a step-type quantitative water-saving irrigation device for high-quality rice in dryland areas. Background Technology

[0002] High-quality dryland rice, also known as upland rice or dryland rice, is a type of rice crop that has been scientifically bred and possesses strong drought-resistant genetic characteristics. It does not mean it doesn't require water, but rather that it can grow normally on dry land or hillsides without flooding, producing high-quality rice. Its core value lies in combining the high quality and yield of rice with the water-saving and drought-resistant capabilities of dryland crops, making it an important technological approach to addressing global water scarcity and ensuring food security.

[0003] However, it must be clear that the "drought resistance" of upland rice is not the same as its "drought-loving" nature. Although it possesses a certain degree of drought tolerance, it is extremely sensitive to water stress throughout its growth cycle, especially during critical water periods—such as the booting, heading, flowering, and grain-filling stages. Even a brief period of severe drought can lead to a significant decrease in yield and damage to quality. Therefore, there is a prominent contradiction between the growing environment of high-quality upland rice and its physiological needs: the crop urgently requires a stable and reliable water supply during key growth stages, while the upland environment in which it grows struggles to provide sufficient and continuous water resources.

[0004] In traditional rice cultivation, irrigation management is often extensive, resulting in low water resource utilization efficiency. However, in dryland farming, water resources are extremely limited and precious, fundamentally changing the nature of irrigation. Irrigation is no longer simply a matter of "supplying water," but rather, in the context of severe water scarcity, a pursuit of "precise, efficient, and controllable" water supply methods to maximize crop water use efficiency. Against this backdrop, how to simultaneously ensure stable, high, and high yields of high-quality dryland rice while improving water resource utilization efficiency has become a core issue that urgently needs to be addressed. Summary of the Invention

[0005] This invention aims to resolve the prominent contradiction between the water sensitivity of high-quality dryland rice during the critical water period and the unstable water supply in dryland environments. By providing a step-type quantitative water-saving irrigation device for high-quality dryland rice, utilizing its unique rotatable truss and guide rod structure, combined with pole anchoring and automatic walking technology, it achieves seamless switching between different irrigation areas in the field and fixed-point quantitative irrigation. Thus, under extremely water-saving technical conditions, it effectively ensures stable, high, and excellent yields of high-quality dryland rice.

[0006] The objective of this invention is achieved through the following technical solution: a step-type quantitative water-saving irrigation device for high-quality dryland rice, comprising truss components, main guide rod components, connecting guide rod components, slide assembly, insertion rod assembly, and irrigation assembly; The main guide rod assembly includes a main lower guide rod, the transition guide rod assembly includes a transition upper guide rod, the insertion rod assembly includes a tapered insertion rod, and the irrigation assembly includes an irrigation head; The bottom of both ends of the truss component is screwed with a transition frame component. Each transition frame component is equipped with a support caster assembly that can be raised and lowered. The support caster assembly can move and turn automatically. The truss member has main upper guide rods fixed to both sides of the lower middle part, and main lower guide rods fixed to the bottom of the main upper guide rods. The transition frame member has transition lower guide rods fixed to both sides of the top, and transition upper guide rods fixed to the top of the transition lower guide rods. The carriage assembly can slide between the main lower guide rods and the main upper guide rods, and also between the transition lower guide rods and the transition upper guide rods. Each carriage assembly has a horizontal connecting rod that can be raised and lowered directly below it, with tapered inserts fixed to the bottom of the horizontal connecting rod; The irrigation assembly is installed directly below the truss member and can move up and down automatically. The irrigation heads are arranged at the bottom of the irrigation assembly.

[0007] The process of using the technical solution of the present invention is as follows: The device can irrigate the entire paddy field area by reciprocating and switching between two sets of support caster assemblies; The entire paddy field can be divided into several smaller plots based on the distance between the two sets of support caster assemblies, and a passageway is provided between two adjacent sets of small paddy field areas to allow the support caster assemblies to move. In the initial state, the two sets of support caster assemblies of the device are placed in the passages on both sides of the first small paddy field that needs to be irrigated, and the main body of the truss component is rotated to a position parallel to the lower guide rod or upper guide rod at both ends. At this time, the device is in the irrigation walking state. Furthermore, during irrigation travel, the carriage assembly is moved to a position that facilitates stable movement of the device without tilting. Furthermore, during irrigation walking mode, the pole assembly is in the upward retracted position; The support caster assembly can move automatically and turn. After the irrigation head is moved down to the root area of ​​the dry rice by the irrigation assembly that can move up and down automatically, it can form an automatic walking irrigation of the dry rice roots. As the support caster assembly moves, the irrigation head can cover a single dryland rice paddy area between the two sets of support caster assemblies and perform mobile irrigation operations on that area, so that the water sprayed from the irrigation head can be injected into the roots of each dryland rice plant. After the irrigation of dryland rice in the current area is completed, the support caster assembly in the channel between the irrigated area and the unirrigated area is used as a reference. The slide assembly is automatically moved to the outside of the support caster assembly on this side, and the lifting drive mechanism connected to the transverse connecting rod is activated, which drives the two sets of transverse connecting rods to move downward, so that each set of conical inserts is inserted downward into the field. The planting row spacing for dryland rice should be greater than the width of the planting pole assembly to ensure that the tapered pole is inserted downwards to a position that will not damage the crops. Then, the lifting drive mechanism connected to the support caster assembly on the other side is activated, which lifts the support caster assembly on that side to a position where it will not touch or crush the seedlings. After the support caster assembly on the other side is raised to its position, the rotary drive mechanism set in the channel between the irrigated area and the unirrigated area is activated, which drives the truss component and the support caster assembly raised to its position to rotate. After the support caster assembly rotates to the channel on the next side of the unirrigated area of ​​the dry rice, the support caster assembly is lowered to the walking position. At this time, the support caster assemblies at both ends of the truss component are located in the channels on both sides of the unirrigated area. Activate the lifting drive mechanism connected to the horizontal connecting rod to drive the conical insert rod upward to a position where it will not touch the dry rice seedlings, and then you can start the walking irrigation of the unirrigated area; By repeating this process, the entire dryland rice field can be irrigated by walking.

[0008] By adopting the above technical solution, the present invention can achieve the following beneficial effects: (1) The device divides the entire paddy field into several irrigation units based on the span between two sets of support caster components, thus realizing zoned operation. During irrigation, the irrigation components that can move up and down automatically can accurately lower the irrigation head to the root area of ​​the dry rice, and complete the coverage irrigation of a single area in the automatic movement of the support caster components. This design ensures that the water directly acts on the roots of the crop. At the same time, the support casters of the device always move in the preset channel, avoiding crushing the seedlings, thus realizing efficient zoned precise irrigation and damage-free movement.

[0009] (2) The device achieves fully automatic switching of irrigation areas through a unique rotation and anchoring design. During switching, the slide assembly moves to the designated side, and the transverse connecting rod of the insertion rod assembly drives the tapered insertion rod to be inserted into the field to form a stable fulcrum. Subsequently, the other side support caster assembly is raised, and the truss component rotates around it until the support caster on that side falls into the next working channel. During this process, the tapered insertion rod effectively resists the overturning moment generated by the rotation, ensuring the stability of the posture and providing a stable and reliable automatic switching mechanism for irrigation areas.

[0010] (3) The guiding system, consisting of the main lower guide rod and main upper guide rod in the main guide rod component and the transition lower guide rod and transition upper guide rod in the transition guide rod component, can provide a complete sliding path for the carriage assembly when the truss component rotates to the working position. This design ensures that the carriage can flexibly adjust its position to maintain overall balance during the device's movement and area switching. At the same time, all components have no structural interference when the truss rotates, ensuring the smoothness and reliability of the mechanism's movement. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0015] In the description of this invention, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and 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. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] like Figures 1-14 As shown, a step-type quantitative water-saving irrigation device for high-quality rice in dryland has a truss component 1 with a connecting frame component 2 screwed to the bottom of both ends. Each set of connecting frame components 2 is equipped with a support caster assembly 3 that can be raised and lowered. The support caster assembly 3 can move and turn automatically. The main guide rod component 4 includes a main lower guide rod 401, and the transition guide rod component 5 includes a transition upper guide rod 502; The truss component 1 has main upper guide rods 402 fixed to both sides of the lower middle part, and main lower guide rods 401 fixed to the lower part of the main upper guide rods 402. The transition frame component 2 has transition lower guide rods 501 fixed to both sides of the top, and transition upper guide rods 502 fixed to the upper part of the transition lower guide rods 501. The carriage assembly 6 can slide between the main lower guide rods 401 and the main upper guide rods 402, and also between the transition lower guide rods 501 and the transition upper guide rods 502. Furthermore, when the main body of the truss component 1 is rotated to a position parallel to the upper guide rod 502 or the lower guide rod 501 at both ends, the position of the lower guide rod 401 on the same side is directly opposite to the lower guide rod 501, and the position of the upper guide rod 402 is directly opposite to the upper guide rod 502, thus forming a complete path that provides sliding guidance for the carriage assembly 6. Furthermore, during the rotation of the truss member 1 relative to the transition member 2 at either end, the transition member 2 and the components fixed to the top of the transition member 2 will not interfere with the truss member 1 and the components fixed to the truss member 1. The insert rod assembly 7 includes a tapered insert rod 706. Each set of slide assembly 6 has a horizontal connecting rod 704 that can be raised and lowered directly below it. The tapered insert rod 706 is arranged and fixed at the bottom end of the horizontal connecting rod 704. The irrigation assembly 8 includes an irrigation head 806. The irrigation assembly 8 is installed directly below the truss member 1 and can move up and down automatically. The irrigation head 806 is arranged at the bottom of the irrigation assembly 8. The working principle is as follows: The device can perform reciprocating irrigation of the entire paddy field area based on the distance between the two sets of support caster assemblies 3; The entire paddy field can be divided into several small blocks based on the distance between the two sets of support caster assemblies 3, and a passage is provided between two adjacent sets of small paddy field areas to allow the support caster assemblies 3 to move. In the initial state, the two sets of support caster assemblies 3 of the device are placed in the passages on both sides of the first small paddy field that needs to be irrigated, and the main body of the truss component 1 is rotated to a position parallel to the lower guide rod 501 or the upper guide rod 502 at both ends. At this time, the device is in the irrigation walking state. Furthermore, during irrigation and walking, the carriage assembly 6 is moved to a position that facilitates stable walking of the device without tilting. This position can be either one of the transition guide rods 5 at either end of the truss member 1 or the middle position of the main guide rod member 4, depending on the actual situation. Furthermore, during irrigation walking mode, the insertion rod assembly 7 is in the upward retracted position, and the bottom end of the tapered insertion rod 706 will not touch the top of the rice seedlings. The support caster assembly 3 can move automatically and can turn. After the irrigation head 806 is moved downward to the root area of ​​the dry rice by the irrigation assembly 8 which can move up and down automatically, an automatic walking irrigation of the dry rice root area can be formed. The spacing between the irrigation heads 806 is determined by the spraying distance of the irrigation water. The greater the spraying distance, the greater the spacing between the irrigation heads 806, and vice versa. As the support caster assembly 3 moves forward, the irrigation head 806 can cover the single dryland rice paddy area between the two sets of support caster assemblies 3 and carry out mobile irrigation operations on the area, so that the water sprayed from the irrigation head 806 can be injected into the roots of each dryland rice plant. After the irrigation of dryland rice in the current area is completed, the support caster assembly 3 in the channel between the irrigated area and the unirrigated area is kept stationary, and the slide assembly 6 is automatically moved to the outside of the support caster assembly 3 on this side. The lifting drive mechanism connected to the transverse connecting rod 704 is activated, which drives the two sets of transverse connecting rods 704 to move downward, so that each set of conical insert rods 706 are inserted downward into the field. At this time, the irrigation area switching state is entered. The planting row spacing of dryland rice should be greater than the setting width of the pole assembly 7 to ensure that the tapered pole 706 is inserted downwards to a position that will not damage the crops; Then, the lifting drive mechanism connected to the support caster assembly 3 on the other side is activated, which drives the support caster assembly 3 on that side to be lifted up to a position where it will not touch or crush the seedlings. After the support caster assembly 3 on the other side is lifted into position, the rotary drive mechanism set in the channel between the irrigated area and the unirrigated area is activated, which drives the truss component 1 and the support caster assembly 3 that has been lifted into position to rotate. At this time, the tapered rod 706 inserted into the field can play a role in stabilizing the rotation. After the support caster assembly 3 rotates to the channel on the next side of the unirrigated area of ​​the dry rice, the support caster assembly 3 is lowered to the walking position. At this time, the support caster assemblies 3 at both ends of the truss component 1 are located in the channels on both sides of the unirrigated area. Activate the lifting drive mechanism connected to the horizontal connecting rod 704 to drive the conical insert rod 706 upward to a position where it will not touch the dry rice seedlings, and then you can start the walking irrigation of the unirrigated area. By repeating this process, the entire field of dryland rice can be irrigated by walking. Furthermore, during the switching process between the irrigated and unirrigated areas, the external pipe connected to the inlet of the irrigation head 806 needs to be plugged and unplugged. That is, during the irrigation operation, the external connecting pipe is connected to the irrigation head 806, and during the irrigation switching operation, in order not to interfere with the rotation of the truss component 1, the external connecting pipe needs to be temporarily disconnected from the irrigation head 806.

[0017] The specific structures of truss component 1, transition frame component 2, supporting caster assembly 3, main guide rod component 4, and transition guide rod component 5 are as follows: Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the lower sides of both ends of the truss tube 101 are fixed with a first rotating seat 102, and the upper sides of both ends are fixed with a second rotating seat 103. The main guide rod component 4 is located in the lower middle part of the truss tube 101. The main lower guide rod 401 and the main upper guide rod 402, as well as the main upper guide rod 402 and the truss tube 101, are fixedly connected by the main connecting frames 403 arranged in a row. A pair of lifting slide columns 201 are vertically fixed between the chassis 202 and the top plate 203. A first rotating shaft 204 is fixedly installed at the top center of the top plate 203, and a second rotating shaft 205 is coaxially fixed at the top of the first rotating shaft 204. The adapter guide rod component 5 is located above the top plate 203. The upper adapter guide rod 502 and the lower adapter guide rod 501, as well as the lower adapter guide rod 501 and the top plate 203, are fixedly connected by the adapter connecting brackets 503 arranged in a row. Furthermore, the second rotating shaft 205 is located in the gap formed between the upper guide rod 502 and the connecting bracket 503, and will not interfere with each other; The first rotary seat 102 on the same side is screwed to the first rotating shaft 204, and the second rotary seat 103 is screwed to the second rotating shaft 205. The steering reduction motor assembly 207 is installed and fixed at the bottom of the top plate 203. A large gear 206 is fixed on the outer ring of the first rotary seat 102. The steering drive gear 208 is inserted and fixed in the output shaft of the steering reduction motor assembly 207 and meshes with the large gear 206. When the steering reduction motor 207 is started, the steering drive gear 208 is rotated, which allows the steering drive gear 208 to cooperate with the large gear 206 for transmission. This drives the truss component 1 to perform a rotational conversion action based on the screw-in engagement between the first rotary seat 102 and the first rotating shaft 204 and the screw-in engagement between the second rotary seat 103 and the second rotating shaft 205. Furthermore, the transmission mechanism consisting of the large gear 206 and the steering drive gear 208 is located in the gap formed between the upper guide rod 502 and the connecting frame 503, so there will be no mutual interference. The bottom support frame 301 is equipped with casters 308 on both sides of the bottom end. The bottom support frame 301 has a pair of lifting slides 302 fixedly installed on the top of the main body. The lifting slides 302 on the same side are slidably connected to the lifting slide column 201. The screw slide 303 is fixedly installed in the middle of the top of the main body of the bottom support frame 301. The bottom center of the first rotating shaft 204 is fixedly connected to the screw top rotating seat 304. The bottom center of the chassis 202 is fixedly installed with the screw bottom rotating seat 305. One end of the lifting screw 306 is screwed to the screw top rotating seat 304 and the other end is screwed to the screw bottom rotating seat 305. A lifting reduction motor assembly 307 is fixedly installed at the bottom of the chassis 202, and the output shaft of the lifting reduction motor assembly 307 is fixedly connected to the bottom of the lifting screw 306. By starting the lifting reduction motor 307, the lifting screw 306 is rotated, so that the lifting screw 306 and the screw slide 303 form a transmission, which can drive the bottom support frame 301 and the caster 308 to move up and down guided by the sliding cooperation between the lifting slide 302 and the lifting slide column 201. To achieve automated operation, the caster 308 integrates a motorized chassis consisting of a drive unit and a steering unit. This motorized chassis can receive and respond to commands from an external control system, including but not limited to machine vision-based field ridge recognition systems, GPS-based path planning systems, or combinations thereof. It should be noted that this type of automatic navigation and control system is a mature and widely documented existing technology in the field of agricultural machinery (such as intelligent tractors and unmanned harvesters). The key design feature of this invention is not the automatic control logic itself, but rather the design of a mechanical structure platform adapted to it, capable of realizing specific irrigation path planning and cross-regional attitude transformation. This platform, through the synergistic effect of the rotatable truss component 1, the main guide rod component 4 with guiding function, and the transition guide rod component 5, enables known automatic walking technology to be applied to the new "reciprocating walking conversion" irrigation method. Therefore, any behavior that uses existing automatic control technology to drive the mechanical structure described in this invention should fall within the protection scope of this invention.

[0018] The specific structures of carriage assembly 6 and insert rod assembly 7 are as follows: Figure 9 , Figure 10 and Figure 11 As shown, the carriage assemblies 6 are distributed in pairs. The lower inner end of the carriage 601 is screwed with a pair of horizontal lower guide wheels 602, and the upper inner end is screwed with a pair of horizontal upper guide wheels 603. The spacing between the horizontal lower guide wheel 602 and the horizontal upper guide wheel 603, the spacing between the main lower guide rod 401 and the main upper guide rod 402, and the spacing between the adapter lower guide rod 501 and the adapter upper guide rod 502 are equal. The synchronous rotating seat 604 is horizontally fixed in the middle of the main body of the slide 601. The sliding motor 607 is installed and fixed on the outside of the slide 601. Synchronous shafts 605 are screwed to both ends of the synchronous rotating seat 604. A vertical guide wheel 606 is inserted and fixed to the inner end of the synchronous shaft 605, and a sprocket 608 is inserted and fixed to the outer end. The rotating shaft of the sliding motor 607 is fixedly connected to the outer end of the synchronous shaft 605 on one side. A chain 609 is sleeved and installed between the sprockets 608. The vertical guide wheel 606 can roll vertically between the main lower guide rod 401 and the main upper guide rod 402 or between the transition lower guide rod 501 and the transition upper guide rod 502; The horizontal lower guide wheel 602 can be rolled in the horizontal direction with the main lower guide rod 401 or the adapter lower guide rod 501, and the horizontal upper guide wheel 603 can be rolled in the horizontal direction with the main upper guide rod 402 or the adapter upper guide rod 502. Furthermore, the main connecting frame 403 connecting the main lower guide rod 401 and the main upper guide rod 402, and the adapter connecting frame 503 connecting the adapter lower guide rod 501 and the adapter upper guide rod 502, will not interfere with the rolling connection formed between the horizontal lower guide wheel 602, the horizontal upper guide wheel 603 and the synchronous rotating seat 604 and the main lower guide rod 401, the main upper guide rod 402, the adapter lower guide rod 501 and the adapter upper guide rod 502; When the sliding motor 607 is started, the chain drive mechanism formed between the sprocket 608 and the chain 609 drives the two sets of vertical guide wheels 606 located in the same set of synchronous rotating seats 604 to rotate synchronously and in the same direction. This enables the vertical guide wheels 606 to automatically roll between the main lower guide rod 401 and the main upper guide rod 402 or between the transition lower guide rod 501 and the transition upper guide rod 502. In conjunction with the rolling connection formed between the horizontal lower guide wheel 602 and the main lower guide rod 401 or the transition lower guide rod 501, and the rolling connection formed between the horizontal upper guide wheel 603 and the main upper guide rod 402 or the transition upper guide rod 502, the carriage assembly 6 can be driven to move automatically along the guide of the main guide rod member 4 or the transition guide rod member 5. Furthermore, during the rotation of the truss component 1 with the transition component 2 at one end as a reference, in order to ensure that the two ends of the main lower guide rod 401 and the main upper guide rod 402, which rotate with the truss component 1, do not interfere with the transition lower guide rod 501 and the transition upper guide rod 502 at the top of the transition component 2, it is necessary to set process seams between the main lower guide rod 401 and the transition lower guide rod 501 and between the main upper guide rod 402 and the transition upper guide rod 502. These seams will not affect the transition work of the carriage assembly 6 between the main guide rod component 4 and the transition guide rod component 5. As for controlling the stopping position of the carriage assembly 6 in the main guide rod component 4 or the transition guide rod component 5, a limit switch can be used, which is existing technology and will not be elaborated here. The top of the fixed rod 701 is fixed to the middle of the outer side of the slide 601. A pair of hydraulic cylinders 702 are installed and fixed in each set of fixed rods 701. The fixed rotating seat 703 is fixed to the bottom end of the telescopic rod of the hydraulic cylinder 702. A pair of connecting rotating shafts 705 are installed and fixed in the main body of the transverse connecting rod 704. The fixed rotating seat 703 on the same side is screwed to the connecting rotating shaft 705. The external hydraulic control system is connected to the hydraulic cylinder 702, which can form the synchronous extension and retraction of the two sets of hydraulic cylinders 702 telescopic rods installed in the same set of fixed rods 701, driving the transverse connecting rod 704 to move stably up and down. The tapered structure of the tapered insertion rod 706 itself is conducive to its insertion and extraction in the field. After the tapered rod 706 is fully inserted into the ground, it forms a fixed pile and a temporary support system with the truss member 1 and the transition member 2 in the rotating state. When the device performs the switching action of lifting and rotating the other support caster assembly 3 based on the support caster assembly 3 on one side, it forms a function to prevent lateral slippage.

[0019] The specific structure of irrigation component 8 is as follows: Figure 12 and Figure 13As shown, the top two sides of the hanger 801 are fixedly connected to the bottom of the main lower guide rod 401 at different positions, and this does not affect the rolling cooperation between the main lower guide rod 401 and the slide assembly 6. The bottom end of the hanger 801 is fixedly installed with a hanging slide seat 802. The top of the main body of the irrigation pipe 804 is fixedly installed with a hanging slide rod 803. The hanging slide rod 803 on the same side is slidably connected to the hanging slide seat 802. The top fixing rod 807 is fixedly connected between the top ends of each set of hanging slide rods 803. The bottom end of the irrigation main pipe 804 is connected to branch pipes 805, and the irrigation head 806 is installed at the outlet end of the branch pipe 805. The water inlet pipe 809 is fixedly connected to one side of the truss pipe 101 through the arranged support seats 810. An electric hoist 808 is installed and fixed in the middle of the truss pipe 101. The bottom end of the wire rope of the electric hoist 808 is fixedly connected to the middle of the top fixing rod 807. The inlet position of the water inlet pipe 809 will not affect the rotation of the truss component 1 relative to the transition frame component 2, nor will it affect the rolling connection of the carriage assembly 6 in the transition guide rod component 5. The irrigation main pipe 804 has a main pipe inlet 811 connected in the middle of its side wall. One end of the connecting hose 812 is connected to the outlet of the water inlet pipe 809, and the other end is connected to the inlet of the main pipe inlet 811. The winding and unwinding action of the wire rope formed by the drum of the electric hoist 808 can generate the lifting and lowering action of the components consisting of the top fixing rod 807, irrigation main pipe 804, branch pipe 805 and irrigation head 806. Furthermore, the flexible structure formed by the material of the connecting hose 812 itself will not affect the lifting and lowering of the components consisting of the top fixing rod 807, the irrigation main pipe 804, the branch pipe 805, and the irrigation head 806. A flow meter 813 is also installed in the inlet pipe 809, which can monitor and measure the irrigation water online. By comparing the measured value with the irrigation quota preset by the control system, the system can automatically cut off the water supply when the cumulative flow reaches the preset threshold, thereby accurately controlling the amount of water applied to each irrigation block, eliminating the waste of water resources and nutrient loss caused by excessive irrigation in traditional irrigation, and directly supporting the device's "quantitative water saving" goal.

[0020] Preferably, such as Figure 5 and Figure 6As shown, a tie rod 9 for stabilizing the truss member 1 is installed between the top end of the second rotating shaft 205 and the truss tube 101. The middle part of the main body of the top rotating frame 901 is screwed to the top end of the second rotating shaft 205. A pair of second stabilizing seats 903 are fixedly connected to both sides of the top end of the truss tube 101. A first stabilizing seat 902 is fixedly connected to both sides of the bottom end of the top rotating frame 901. Tie rod joints 904 are screwed into both the first stabilizing seat 902 and the second stabilizing seat 903. A tie rod 905 is fixedly connected between the tie rod joint 904 screwed to the first stabilizing seat 902 and the tie rod joint 904 screwed to the second stabilizing seat 903. This can form a pulling effect on the frame of the truss tube 101 relative to the second rotating shaft 205, eliminating the sagging phenomenon of the truss tube 101 due to its excessive frame length during the rotation of the truss member 1 with the transition frame member 2 as the reference.
