Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of energy-saving irrigation, in particular to an automatic sprinkling irrigation control device and method for field crops. BACKGROUND

[0002] Field crops refer to crops suitable for large-scale open planting (such as wheat, corn, rice, cotton, etc.), and the irrigation of such crops often uses micro-spraying pipes. The water sprayed from the water outlet holes of the micro-spraying pipe forms a fine rain-like spraying effect under the combined action of gravity and air resistance, which not only makes the irrigation more uniform and sufficient and avoids the ground from drying out, but also has the characteristics of wide application range and water saving.

[0003] The utility model patent with the publication number CN223515452U discloses a kind of anti-tumbling micro-spraying pipes, which include pipe body and wing belt arranged on the pipe body;The wing belt is below the middle part of the pipe body and in contact with the ground, which can improve the stability of the pipe body and prevent it from tumbling. However, such micro-spraying pipes are still prone to tumbling in strong winds, which cannot ensure that the water outlet holes are always facing upwards, and manual straightening is required, thereby affecting the irrigation efficiency. SUMMARY

[0004] Therefore, it is necessary to provide an automatic sprinkling irrigation control device and method for field crops to solve the technical problem that the current micro-spraying pipes are prone to tumbling and affect the irrigation efficiency.

[0005] The above-mentioned purpose is achieved by the following technical solutions: An automatic sprinkling irrigation control device for field crops includes a micro-spraying pipe, a straightening assembly and a traction mechanism. The micro-spraying pipe is provided with water outlet holes, which are distributed on the upper surface of the micro-spraying pipe. The length direction of the micro-spraying pipe is defined as the front-rear direction, and the horizontal direction perpendicular to the length direction is defined as the left-right direction. The left and right sides of the micro-spraying pipe are respectively provided with sliding rails, which extend along the front-rear direction. The straightening assembly includes a sliding ring, which is coaxially and slidingly sleeved on the micro-spraying pipe, and the inner periphery of the sliding ring is in contact with the micro-spraying pipe. The traction mechanism can drive the sliding ring to move back and forth along the sliding rails on both sides of the micro-spraying pipe. When the micro-spraying pipe is turned around its axis due to external force, the sliding ring can straighten the micro-spraying pipe by moving back and forth, thereby maintaining the water outlet holes in an upward position.

[0006] Further, a cleaning block is arranged between the sliding ring and the micro-spraying pipe. The cleaning block is an arc-shaped block, and the axis of the cleaning block coincides with the axis of the micro-spraying pipe. The inner periphery of the cleaning block is in contact with the outer periphery of the micro-spraying pipe. The outer periphery of the cleaning block is coaxially provided with an arc-shaped protrusion, and the inner periphery of the sliding ring is coaxially provided with an arc-shaped groove. The arc-shaped protrusion can slide back and forth in the arc-shaped groove.

[0007] Furthermore, both the front and rear end faces of the cleaning block are inclined surfaces, which are used to guide dust from the surface of the micro-spray nozzle into the arc-shaped groove.

[0008] Furthermore, the sliding ring includes an arc-shaped piece in the middle and sliders at the left and right ends. The arc-shaped groove is disposed on the inner circumferential surface of the arc-shaped piece. Each slider is U-shaped, and the inner wall of the slider is provided with two balls, one above the other. The two balls can roll along the upper and lower sides of the slide rail respectively.

[0009] Furthermore, the sliding ring is made of an elastic material, and the slider can slide radially along the slide rail, thereby causing the arc-shaped plate to stretch and deform in the left and right direction, which in turn can compress the micro-nozzle.

[0010] Furthermore, the traction mechanism includes a front support and a rear support disposed at the front and rear ends of the micro-nozzle; a first rope and a second rope are respectively connected to the sliders on the left and right sides of the sliding ring; the front support is provided with a front traction component for traction of the front ends of the first rope and the second rope; the rear support is provided with a rear traction component for traction of the rear ends of the first rope and the second rope; by controlling the front traction component to synchronously wind up the front ends of the first rope and the second rope, and by controlling the rear traction component to synchronously unwind the rear ends of the first rope and the second rope, the sliding ring can slide forward; by controlling the front traction component to synchronously unwind the front ends of the first rope and the second rope, and by controlling the rear traction component to synchronously wind up the rear ends of the first rope and the second rope, the sliding ring can slide backward.

[0011] Furthermore, the front traction assembly includes a first drive wheel and a second drive wheel located on the left and right sides of the micro-nozzle. A third drive wheel is coaxially arranged below the first drive wheel, and a fourth drive wheel is coaxially arranged below the second drive wheel. The front end of the first rope is wound around the third drive wheel, and the front end of the second rope is wound around the fourth drive wheel. The first and second drive wheels are jointly connected to a first drive rope, which is connected to a first winding motor. The first winding motor controls the first and second drive wheels to rotate synchronously, enabling the third and fourth drive wheels to wind up or... Unwinding; the rear traction assembly includes a fifth drive wheel and a sixth drive wheel located on the left and right sides of the micro-nozzle, a seventh drive wheel coaxially arranged below the fifth drive wheel, and an eighth drive wheel coaxially arranged below the sixth drive wheel; the rear end of the first rope is wound around the seventh drive wheel, and the rear end of the second rope is wound around the eighth drive wheel; the fifth and sixth drive wheels are jointly driven by a second drive rope, which is connected to a second take-up motor; by controlling the fifth and sixth drive wheels to rotate synchronously through the second take-up motor, the seventh and eighth drive wheels can be used to wind or unwind the rear ends of the first and second ropes.

[0012] Furthermore, the distance between the first and second transmission wheels is equal to the distance between the fifth and sixth transmission wheels, and both are greater than the distance between the two sliders of the sliding ring. When the front traction component synchronously winds up the front ends of the first and second ropes, and the rear traction component synchronously winds up the rear ends of the first and second ropes, the first and second ropes can pull the two sliders of the sliding ring away from each other, causing the arc-shaped piece on the sliding ring to stretch and deform in the left and right directions, thereby squeezing the micro-nozzle.

[0013] Furthermore, the micro-spray pipe is provided with multiple micro-spray pipes arranged in parallel. The front ends of the multiple micro-spray pipes are all connected to a first main water pipe, and the rear ends of the multiple micro-spray pipes are all connected to a second main water pipe. The first main water pipe or the second main water pipe is connected to a water pump, and the water pump supplies water to the first main water pipe or the second main water pipe.

[0014] An automated sprinkler irrigation control method for field crops, employing the aforementioned automated sprinkler irrigation control device for field crops, includes the following steps: S1. Water is introduced into the micro-sprinkler pipe, so that the water is sprayed out from the water outlet to irrigate the field crops; S2. Determine the state of the micro-nozzle. When the micro-nozzle is observed to flip, control the traction mechanism to pull the sliding ring back and forth on the micro-nozzle, so that the sliding ring can straighten the micro-nozzle.

[0015] The beneficial effects of this invention are: The automated sprinkler irrigation control device and control method for field crops provided by the present invention firstly, when the micro-sprinkler is overturned due to external force, the sliding ring slides back and forth along the slide rail to straighten the micro-sprinkler, so as to keep the water outlet in the upward position and ensure the irrigation effect of the micro-sprinkler.

[0016] Secondly, when the sliding ring straightens the micro-sprinkler, the cleaning block can remove dust from the surface of the micro-sprinkler, preventing blockage of the water outlet and thus avoiding pump stalling or micro-sprinkler rupture, ensuring smooth irrigation. At the same time, the sliding ring can block some of the water flowing out of the water outlet during its movement, allowing it to rinse the surface of the micro-sprinkler and improving the cleaning effect.

[0017] Third, when winding up the micro-nozzle, the arc-shaped sheet can be stretched and deformed to compress the micro-nozzle, allowing the water inside the micro-nozzle to be discharged as quickly as possible. Attached Figure Description

Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0023] like Figures 1 to 12As shown, an embodiment of the present invention provides an automated sprinkler irrigation control device for field crops, including a micro-sprinkler 105 mounted on the ground 100, a straightening component, and a traction mechanism; the micro-sprinkler 105 is provided with water outlets (not shown in the figure), the water outlets are distributed on the upper surface of the micro-sprinkler 105, the length direction of the micro-sprinkler 105 is defined as the front-back direction, the horizontal direction of the micro-sprinkler 105 perpendicular to the length direction is defined as the left-right direction, and slide rails 1051 are respectively provided on the left and right sides of the micro-sprinkler 105. 051 extends in the front-to-back direction; the straightening component includes a sliding ring 110, which is coaxially slidably sleeved on the micro-spray nozzle 105, and the inner circumferential surface of the sliding ring 110 is in contact with the micro-spray nozzle 105; the traction mechanism can pull the sliding ring 110 to move back and forth along the slide rails 1051 on both sides of the micro-spray nozzle 105; when the micro-spray nozzle 105 flips around its axis due to external force, the sliding ring 110 straightens the micro-spray nozzle 105 by moving back and forth, thereby maintaining the water outlet in an upward position. The slide rail 1051 has a T-shaped cross-section and is arranged horizontally.

[0024] When the micro-sprinkler 105 is flipped due to external force, the sliding ring 110 slides back and forth along the slide rail 1051 to straighten the micro-sprinkler 105, so that the water outlet can be kept in the upward position to ensure the irrigation effect of the micro-sprinkler 105.

[0025] Furthermore, a cleaning block 112 is provided between the sliding ring 110 and the micro-spray nozzle 105. The cleaning block 112 is an arc-shaped block, and the axis of the cleaning block 112 coincides with the axis of the micro-spray nozzle 105. The inner circumferential surface of the cleaning block 112 is in contact with the outer circumferential surface of the micro-spray nozzle 105. The outer circumferential surface of the cleaning block 112 is coaxially provided with an arc-shaped protrusion, and the inner circumferential surface of the sliding ring 110 is coaxially provided with an arc-shaped groove. The arc-shaped protrusion can slide back and forth in the arc-shaped groove.

[0026] In this way, when the sliding ring 110 straightens the micro-sprinkler 105, the cleaning block 112 can clean the dust on the surface of the micro-sprinkler 105, preventing the water outlet from becoming blocked and causing pump stalling or the micro-sprinkler 105 to be punctured, thus ensuring smooth irrigation. At the same time, the sliding ring 110 can block some of the water flowing out of the water outlet during its movement, allowing it to rinse the surface of the micro-sprinkler 105 and improving the cleaning effect.

[0027] Furthermore, both the front and rear end faces of the cleaning block 112 are beveled, which guide dust from the surface of the micro-spray nozzle 105 into the arc-shaped groove. This facilitates dust collection, and the beveled surfaces can scrape away dust from the surface of the micro-spray nozzle 105, improving the cleaning effect.

[0028] Furthermore, the sliding ring 110 includes an arc-shaped piece 1101 located in the middle and sliders 1102 located at the left and right ends. The arc-shaped groove is provided on the inner circumferential surface of the arc-shaped piece 1101. Each slider 1102 is U-shaped, and the inner wall of the slider 1102 is provided with two upper and lower balls 113. The two balls 113 can roll along the upper and lower sides of the slide rail 1051 respectively. In this way, the sliding ring 110 slides back and forth along the slide rail 1051 via the sliders 1102, which can straighten the twisted micro-nozzle 105, thereby achieving the straightening of the micro-nozzle 105. Moreover, the balls 113 can reduce the sliding resistance and make the sliding smoother.

[0029] Furthermore, the sliding ring 110 is made of an elastic material, and the slider 1102 can slide radially along the micro-nozzle 105 on the slide rail 1051, thereby causing the arc-shaped plate 1101 to undergo tensile deformation in the left and right directions, which in turn can compress the micro-nozzle 105.

[0030] In this way, when the micro-nozzle 105 is wound up, the arc-shaped piece 1101 can be stretched and deformed to squeeze the micro-nozzle 105, so that the water inside the micro-nozzle 105 can be discharged as soon as possible.

[0031] Furthermore, the traction mechanism includes a front support 107 and a rear support 118 disposed at the front and rear ends of the micro-nozzle 105; a first rope 106 and a second rope 117 are respectively connected to the sliders 1102 on the left and right sides of the sliding ring 110; the front support 107 is provided with a front traction component for traction of the front ends of the first rope 106 and the second rope 117; the rear support 118 is provided with a rear traction component for traction of the rear ends of the first rope 106 and the second rope 117; by controlling the front traction component to synchronously wind up the front ends of the first rope 106 and the second rope 117, and by controlling the rear traction component to synchronously unwind the rear ends of the first rope 106 and the second rope 117, the sliding ring 110 can be made to slide forward; by controlling the front traction component to synchronously unwind the front ends of the first rope 106 and the second rope 117, and by controlling the rear traction component to synchronously wind up the rear ends of the first rope 106 and the second rope 117, the sliding ring 110 can be made to slide backward. The front traction assembly and the rear traction assembly have the same structure and correspond to each other front to back. The first rope 106 and the second rope 117 have the same structure and correspond to each other left to right.

[0032] By controlling the release and retraction of the first rope 106 and the second rope 117 through the front traction assembly and the rear traction assembly, precise control of the sliding ring 110 can be achieved.

[0033] Furthermore, the front traction assembly includes a first drive wheel 108 and a second drive wheel 109 located on the left and right sides of the micro-nozzle 105. A third drive wheel 114 is coaxially arranged below the first drive wheel 108, and a fourth drive wheel 115 is coaxially arranged below the second drive wheel 109. The front end of the first rope 106 is wound around the third drive wheel 114, and the front end of the second rope 117 is wound around the fourth drive wheel 115. The first drive wheel 108 and the second drive wheel 109 are jointly connected to a first drive rope 120. The first drive rope 120 is connected to a first winding motor 103. The first winding motor 103 controls the first drive wheel 108 and the second drive wheel 109 to rotate synchronously, enabling the third drive wheel 114 and the fourth drive wheel 115 to rotate in tandem with the first drive wheel 109. The front ends of rope 106 and the front ends of the second rope 117 are wound or unwound; the rear traction assembly includes a fifth drive wheel and a sixth drive wheel located on the left and right sides of the micro-nozzle 105, a seventh drive wheel coaxially arranged below the fifth drive wheel, and an eighth drive wheel coaxially arranged below the sixth drive wheel; the rear end of the first rope 106 is wound around the seventh drive wheel, and the rear end of the second rope 117 is wound around the eighth drive wheel. The fifth and sixth drive wheels are connected to a second drive rope, which is connected to a second winding motor 119; the second winding motor 119 controls the fifth and sixth drive wheels to rotate synchronously, enabling the seventh and eighth drive wheels to wind or unwound the rear ends of the first rope 106 and the second rope 117.

[0034] Specifically, the axes of the first drive wheel 108, the second drive wheel 109, the fifth drive wheel, and the sixth drive wheel all extend in the vertical direction. The first drive rope 120 is provided with multiple first connecting ropes, which are fixedly connected to each of the first drive wheels 108 and the second drive wheel 109. The second drive rope is provided with multiple second connecting ropes, which are fixedly connected to each of the fifth drive wheels and the sixth drive wheel.

[0035] Furthermore, the distance between the first transmission wheel 108 and the second transmission wheel 109 is equal to the distance between the fifth transmission wheel and the sixth transmission wheel, and both are greater than the distance between the two sliders 1102 of the sliding ring 110. When the front traction component synchronously winds up the front end of the first rope 106 and the front end of the second rope 117, and the rear traction component synchronously winds up the rear end of the first rope 106 and the rear end of the second rope 117, the first rope 106 and the second rope 117 can pull the two sliders 1102 of the sliding ring 110 away from each other, causing the arc-shaped piece 1101 on the sliding ring 110 to undergo tensile deformation in the left and right directions, thereby squeezing the micro-nozzle 105.

[0036] When both ends of the first rope 106 and the second rope 117 are stretched, the first rope 106 and the second rope 117 will become taut. This tautness causes the first rope 106 and the second rope 117 to pull the two sliders 1102 of the sliding ring 110 away from each other. The arc-shaped plate 1101 will then undergo tensile deformation, thereby compressing the micro-nozzle 105. Both the first rope 106 and the second rope 117 are equipped with rope connectors 1061, which are fixed to the sliders 1102 by pins 111.

[0037] Tension gauges (not shown in the figure) are installed on the first rope 106 or the second rope 117. The tension gauges continuously collect tension values ​​and feed the signals back to the control system. The control system adjusts the winding and unwinding speeds of the first winding motor 103 and the second winding motor 119. When the micro-nozzle 105 is winding, the tension of the first rope 106 and the second rope 117 is sufficient to stretch the two sliders 1102 of the sliding ring 110, while preventing the first rope 106 and the second rope 117 from breaking. When the first rope 106 or the second rope 117 breaks, the control system can automatically stop the first winding motor 103 and the second winding motor 119.

[0038] Furthermore, the micro-spray nozzles 105 are provided in multiple parallel configurations. The front ends of the multiple micro-spray nozzles 105 are all connected to a first main water pipe 116, and the rear ends of the multiple micro-spray nozzles 105 are all connected to a second main water pipe 102. A water pump 101 is connected to either the first main water pipe 116 or the second main water pipe 102, and the water pump 101 supplies water to either the first main water pipe 116 or the second main water pipe 102.

[0039] The micro-spray nozzle 105 is fixedly connected to the first main water pipe 116 and the second main water pipe 102 by a clamp 104.

[0040] Based on the above embodiments, the usage principle and working process of the embodiments of the present invention are as follows: Multiple parallel micro-sprinklers 105 are connected to form an irrigation network through a first main water pipe 116 and a second main water pipe 102, ensuring that the water outlet holes on the upper surface of the micro-sprinklers 105 initially face upwards.

[0041] When the water pump 101 is started, the water flows through the first main water pipe 116 or the second main water pipe 102 and is distributed to each micro-sprinkler pipe 105. Under the action of water pressure, the water is evenly sprayed out from the water outlet hole on the upper surface of the micro-sprinkler pipe 105, forming an irrigation water curtain covering the crop planting area, and realizing large-area synchronous irrigation.

[0042] When the micro-sprinkler 105 flips around its own axis due to external forces such as strong winds or collisions with field machinery, the first winding motor 103 and the second winding motor 119 are controlled to drive the sliding ring 110 to slide back and forth 1-2 times on the slide rail 1051 of the micro-sprinkler 105. During the movement, the sliding ring 110 straightens the micro-sprinkler 105, pulling it back to its initial state, ensuring that the water outlet is facing upwards again, restoring the normal irrigation direction. As the sliding ring 110 slides back and forth on the micro-sprinkler 105, the cleaning block 112 cleans the dust on the surface of the micro-sprinkler 105 to prevent the water outlet from becoming blocked. At the same time, the sliding ring 110 collects some of the water sprayed from the water outlet to clean the surface of the micro-sprinkler 105, further reducing the probability of the water outlet becoming blocked.

[0043] Upon completion of irrigation, the first winding motor 103 and the second winding motor 119 are controlled to synchronously wind up the front and rear traction components. This stretches and straightens both the first rope 106 and the second rope 117. The tension generated by the straightening of the first rope 106 and the second rope 117 pulls the two sliders 1102 on the sliding ring 110 away from each other, forcing the arc-shaped plate 1101 to undergo tensile deformation in the left and right directions. This allows the arc-shaped plate 1101 to squeeze the micro-sprinkler 105, causing the water inside the micro-sprinkler 105 to be discharged. Finally, the sliding ring 110 is disassembled, and the micro-sprinkler 105 is wound up, completing the irrigation operation.

[0044] An embodiment of an automated sprinkler irrigation control method for field crops, employing the aforementioned automated sprinkler irrigation control device for field crops, includes the following steps: S1. Water is introduced into the micro-sprinkler 105 so that the water is sprayed out from the outlet to irrigate the field crops. S2. Determine the state of the micro-nozzle 105. When it is observed that the micro-nozzle 105 has flipped, control the traction mechanism to pull the sliding ring 110 to move back and forth on the micro-nozzle 105, so that the sliding ring 110 can straighten the micro-nozzle 105.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.

By controlling the front traction assembly to simultaneously wind up the front ends of the first and second ropes, and controlling the rear traction assembly to simultaneously unwind the rear ends of the first and second ropes, the sliding ring can slide forward; by controlling the front traction assembly to simultaneously unwind the front ends of the first and second ropes, and controlling the rear traction assembly to simultaneously wind up the rear ends of the first and second ropes, the sliding ring can slide backward.

7. The automated sprinkler irrigation control device for field crops according to claim 6, characterized in that, The front traction assembly includes a first drive wheel and a second drive wheel located on the left and right sides of the micro-nozzle. A third drive wheel is coaxially arranged below the first drive wheel, and a fourth drive wheel is coaxially arranged below the second drive wheel. The front end of the first rope is wound around the third drive wheel, and the front end of the second rope is wound around the fourth drive wheel. The first drive wheel and the second drive wheel are connected to a first drive rope, which is connected to a first winding motor. The first winding motor controls the first drive wheel and the second drive wheel to rotate synchronously, enabling the third drive wheel and the fourth drive wheel to wind up or unwind the front ends of the first rope and the second rope. The rear traction assembly includes a fifth drive wheel and a sixth drive wheel located on the left and right sides of the micro-nozzle. A seventh drive wheel is coaxially arranged below the fifth drive wheel, and an eighth drive wheel is coaxially arranged below the sixth drive wheel. The rear end of the first rope is wound around the seventh drive wheel, and the rear end of the second rope is wound around the eighth drive wheel. The fifth and sixth drive wheels are connected to a second drive rope, which is connected to a second winding motor. By controlling the fifth and sixth drive wheels to rotate synchronously through the second winding motor, the seventh and eighth drive wheels can wind or unwind the rear ends of the first and second ropes.

8. The automated sprinkler irrigation control device for field crops according to claim 7, characterized in that, The distance between the first and second transmission wheels is equal to the distance between the fifth and sixth transmission wheels, and both are greater than the distance between the two sliders of the sliding ring. When the front traction component synchronously winds up the front ends of the first and second ropes, and the rear traction component synchronously winds up the rear ends of the first and second ropes, the first and second ropes can pull the two sliders of the sliding ring away from each other, causing the arc-shaped plate on the sliding ring to stretch and deform in the left and right directions, thereby squeezing the micro-nozzle.
