Description

Technical Field

[0001] The present invention relates to the technical field of sprinkler irrigation, in particular to a sprinkler irrigation device for wheat crops and a control method thereof. Background Art

[0002] Wheat, a collective term for wheat plants, belongs to the Poaceae family and is widely cultivated worldwide. It is one of the earliest crops cultivated by humans. It is extremely nutritious, containing starch, protein, fat, minerals, and many other substances beneficial to the human body. It is a key link in the human food supply chain. With the development of technology, wheat irrigation systems with integrated water and fertilizer have undergone continuous technological innovation to help wheat thrive and ensure a good harvest.

Although the sprinkler irrigation device drives the sprinkler head to adjust the height by adjusting the adjustment rod to achieve the control of the spraying range, when spraying liquid fertilizer, the liquid fertilizer will be sprayed directly on the leaves of the wheat crop, and some of the liquid fertilizer will also flow into the narrow gaps between the leaves. Even if it is subsequently flushed with irrigation water, the liquid fertilizer remaining in the gaps is extremely difficult to be completely removed, which can easily cause seedling burn and affect the growth of wheat.

[0018] The beneficial effects of the present invention are as follows:

[0019] (1) The present invention uses a lifting frame to carry the diversion bin for lifting and lowering movement, first prompting the Z-shaped sprinkler pipe to descend to spray liquid fertilizer on the roots and stems of wheat crops, which can effectively avoid the problem of liquid fertilizer being sprinkled on the leaves and causing seedling burns, and then drives the Z-shaped sprinkler pipe to rise to spray irrigation water on the leaves, realizing the integrated spraying of fertilizer and water while washing the liquid fertilizer on the leaves, thereby achieving the effect of efficient sprinkler irrigation for wheat crops; and by means of a trapezoidal irrigation bin combined with a plurality of inclined liquid outlet pipes, while promoting sprinkler irrigation, the impeller carries the Z-shaped sprinkler pipe to rotate, forming a circular liquid fertilizer spraying path, eliminating the obstruction of liquid fertilizer spraying caused by the roots and stems of wheat crops, and further improving the effect of liquid fertilizer spraying;

[0039] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0040] Example 1: Please refer to Figure 1-Figure 3 、 Figure 5-Figure 12 As shown, the problem of spraying liquid fertilizer on the leaves of wheat crops in the prior art, which easily causes seedling burn, can be solved by the following solution:

[0041] The wheat crop sprinkler irrigation device in this embodiment includes a mobile body 1, which is used for the overall movement of the device, thereby achieving mobile sprinkler irrigation processing, thereby improving the spraying uniformity of liquid fertilizer and irrigation water. A water tank 11 and a fixing seat 12 are fixedly installed on the top of the mobile body 1. The water tank 11 is used to store liquid fertilizer and sprinkler water, and a cleaning type retractable assembly 2 is provided on the water tank 11. The cleaning type retractable assembly 2 includes a mounting frame 21 welded to one side of the water tank 11. A retractable wheel 22 is rotatably mounted on the mounting frame 21. The retractable wheel 22 is combined with the movement of the mobile body 1 to reel in and out a reeled water pipe (not shown), and a guide sleeve 23 is movably installed.

[0042] A lifting frame 13 is slidably connected to the fixed seat 12, and a sprinkler assembly 3 is provided on the lifting frame 13. The lifting frame 13 is used to adjust the height of the sprinkler assembly 3, thereby facilitating adaptive spraying height adjustment of liquid fertilizer and irrigation water, thereby avoiding spraying liquid fertilizer onto the leaves of wheat crops, which may easily cause seedling burning. The sprinkler assembly 3 includes a diversion chamber 31 and a trapezoidal liquid injection chamber 32 installed on one side of the diversion chamber 31. The bottom of the diversion chamber 31 is equidistantly connected to a number of Z-shaped sprinkler pipes 33 for increasing the width of the linear spraying path during the movement of the mobile body 1, thereby improving the spraying efficiency.

[0043] In addition, several Z-shaped sprinkler pipes 33 are rotatably connected to the same auxiliary plate, which prompts multiple Z-shaped sprinkler pipes 33 to rotate, thereby improving the anti-blocking spraying effect. The bottom of the Z-shaped sprinkler pipe 33 is threadedly connected to a sprinkler head. The threaded connection method facilitates the replacement of sprinkler heads with different spraying methods. One end of the Z-shaped sprinkler pipe 33 passes through the diversion bin 31 and is installed with an impeller 34, which is used to drive the Z-shaped sprinkler pipe 33 to rotate.

[0044] The water storage tank 11 is provided with a water storage chamber 14 and a fertilizer storage chamber 15. Irrigation water is added to both the water storage chamber 14 and the fertilizer storage chamber 15, and a corresponding amount of concentrated liquid fertilizer is placed in the fertilizer storage chamber 15 for dilution and mixing. The water storage tank 11 is respectively provided with a cover for injecting liquid into the water storage chamber 14 and the fertilizer storage chamber 15. The cover on the fertilizer storage chamber 15 is a ventilated cover, and the cover on the water storage chamber 14 is a sealed cover. A connecting pipe 16 rotatably connected to the retractable wheel 22 is installed on the mounting frame 21.

[0045] A cavity communicating with the connecting pipe 16 is provided inside the retractable wheel 22, and a threaded hole communicating with the cavity is provided on the annular wall of the retractable wheel 22, and the threaded hole is threadedly connected to the water pumping pipe. The water pumping pipe is wound around the retractable wheel 22, and a first motor 24 for driving the retractable wheel 22 to rotate is used to drive the retractable wheel 22 to rotate, thereby releasing and reeling in the water pumping pipe. The connecting pipe 16 is communicated with the water storage chamber 14.

[0046] A water pump 17 is bolted to the mobile body 1, and the water inlet of the water pump 17 is connected to a water suction pipe 19 and a fertilizer suction pipe 110 through a three-way valve 18. The water suction pipe 19 is in communication with the water storage chamber 14, and the fertilizer suction pipe 110 is in communication with the fertilizer storage chamber 15. The mobile body 1 moves with the sprinkler assembly 3, and the three-way valve 18 controls the fertilizer suction pipe 110 to be in communication with the water pump 17. The water pump 17 extracts liquid fertilizer through the fertilizer suction pipe 110. The three-way valve 18 controls the water suction pipe 19 to be in communication with the water pump 17, and the water pump 17 extracts irrigation water through the water suction pipe 19.

[0047] An injection pipe 111 is connected between the water outlet of the water pump 17 and the trapezoidal injection tank 32. The liquid fertilizer or irrigation water pumped by the water pump 17 is injected into the trapezoidal injection tank 32 through the injection pipe 111. When the water pump 17 extracts irrigation water from the water storage tank 11, as the irrigation water in the water storage chamber 14 decreases, the internal air pressure decreases, and then the water in the external water pool is extracted through the pumping pipe on the retractable wheel 22 and the connecting pipe 16, and a large amount of irrigation water is sprayed.

[0048] The positions of the trapezoidal liquid injection chamber 32 corresponding to the impellers 34 are all fixedly connected to inclined liquid outlet pipes 35. One end of the liquid outlet pipe 111 is located on the length and width side of the trapezoidal liquid injection chamber 32. By configuring the trapezoidal liquid injection chamber 32 into a trapezoidal structure and positioning the liquid outlet pipe 111 on the length and width side, the liquid in the trapezoidal liquid injection chamber 32 is discharged from the multiple liquid outlet pipes 35. When the liquid is discharged from the multiple liquid outlet pipes 35, the outlet pressure at each location is equal, thereby effectively driving the impellers 34 to rotate.

[0049] Liquid fertilizer or irrigation water is injected into the trapezoidal liquid injection tank 32 through the liquid injection pipe 111, and then sprayed to the diversion tank 31 through multiple liquid outlet pipes 35. The liquid fertilizer solution in the diversion tank 31 enters the Z-shaped sprinkler pipe 33 and is then sprayed out through the corresponding sprinkler head. At the same time, the liquid fertilizer solution sprayed out through the inclined liquid outlet pipe 35 causes the multiple impellers 34 to rotate.

[0050] A lifting screw 112 is rotatably connected to the fixed base 12 and is threadedly connected to the lifting frame 13. A second motor 113 is installed on the fixed base 12 to drive the lifting screw 112 to rotate. The second motor 113 drives the lifting screw 112 to rotate, and the lifting screw 112 drives the lifting frame 13 to move up and down. The lifting frame 13 moves downward, placing the sprinkler head on the Z-shaped sprinkler pipe 33 under the leaves of the wheat crop. The mobile body 1 carries the sprinkler assembly 3 to move, that is, spraying liquid fertilizer;

[0051] The lifting screw 112 drives the lifting frame 13 to move upward, placing the sprinkler head on the Z-shaped sprinkler pipe 33 above the leaves of the wheat crop to spray irrigation water on the wheat crop and at the same time wash away some of the liquid fertilizer splashed onto the leaves. A U-shaped frame 114 hinged to the diversion chamber 31 is welded on the lifting frame 13, and an electric push rod 115 is hinged between the U-shaped frame 114 and the diversion chamber 31. By extending the telescopic rod of the electric push rod 115, the diversion chamber 31 is driven to deflect in the vertical direction, further adjusting the spraying height and expanding the spraying range.

[0052] The impeller 34 is sleeved on the outside of the corresponding Z-shaped sprinkler pipe 33, and the impeller 34 is rotatably connected to a support rod that is slidably connected to the diversion chamber 31. The ends of each support rod are fixedly connected to the same movable plate 36, and the top of the movable plate 36 is fixedly connected to an auxiliary block hinged to the U-shaped frame 114;

[0053] The hinge points of the auxiliary block, the diversion bin 31 and the U-shaped frame 114 are staggered. The diversion bin 31 is driven to deflect in the vertical direction by extending the telescopic rod of the electric push rod 115. During the deflection of the diversion bin 31, the movable plate 36 is driven to move away from the diversion bin 31 by means of the hinge of the auxiliary block and the U-shaped frame 114. The movable plate 36 drives multiple impellers 34 to move through the support plate, thereby reducing the degree of contact with the water sprayed from the liquid outlet pipe 35 and avoiding increasing the water outlet resistance. The movement of the impeller 34 causes the liquid outlet 37 to expand, increase the water output, improve the spraying range, and ensure that the spraying amount in each area remains unchanged.

[0054] A plurality of liquid outlets 37 are provided on the outer wall of the Z-shaped sprinkler pipe 33 and inside the diversion chamber 31. A connecting block 38 is fixedly connected to the annular inner wall of the impeller 34, which slides with the liquid outlet 37. The liquid fertilizer solution in the diversion chamber 31 enters the Z-shaped sprinkler pipe 33 through the liquid outlet 37. The rotating impeller 34 cooperates with the liquid outlet 37 through the connecting block 38 and the auxiliary plate, thereby causing the multiple Z-shaped sprinkler pipes 33 to rotate synchronously, forming a circular spraying path, thereby eliminating the obstruction of the liquid fertilizer spraying caused by the roots and stems of the wheat crops.

[0055] Example 2: Please refer to Figure 2-Figure 4 As shown, the problem of difficulty in evenly winding the water pump pipe and cleaning the surface impurities can be solved by the following solutions:

[0056] In this embodiment, a reciprocating screw rod 25 threadedly connected to the guide sleeve 23 is rotatably installed in the mounting frame 21. The reciprocating screw rod 25 drives the guide sleeve 23 to reciprocate, assisting in the uniform winding of the reeled water pumping pipe, and a guide rod sliding with the guide sleeve 23 is fixedly installed. The guide rod is used to cause the guide sleeve 23 to reciprocate under the drive of the reciprocating screw rod 25. Sprockets 26 are installed on the axles of the reciprocating screw rod 25 and the retracting wheel 22, and the sprockets 26 are connected by chains 27. The first motor 24 drives the retracting wheel 22 to rotate, and the released water pumping pipe is reeled in. The rotation of the retracting wheel 22 cooperates with the sprocket 26 and the chain 27 to drive the reciprocating screw rod 25 to rotate.

[0057] A gear ring 28 is rotatably mounted on the guide sleeve 23, and an annular cleaning brush 29 is mounted on the internal bolts of the gear ring 28. A toothed plate 210 meshing with the gear ring 28 is fixedly connected to the mounting frame 21. The reciprocating motion of the guide sleeve 23 causes the gear ring 28 meshing with the toothed plate 210 to carry the internal annular cleaning brush 29 to rotate, thereby simultaneously cleaning impurities on the surface of the wound water suction pipe. A guide guard ring 211 is fixedly mounted on the gear ring 28, which is used to cooperate with the guide sleeve 23 to assist both sides of the annular cleaning brush 29, thereby avoiding increased wear on the annular cleaning brush 29 and thereby increasing the service life of the annular cleaning brush 29.

[0058] Example 3: Please refer to Figures 1-12 As shown, the present invention also provides a method for controlling sprinkler irrigation water for wheat crops, comprising the following steps:

[0059] Step 1: Rotary liquid fertilizer spraying process, specifically the following steps: Irrigation water is added to both the water storage chamber 14 and the fertilizer storage chamber 15, and a corresponding amount of concentrated liquid fertilizer is placed in the fertilizer storage chamber 15 for dilution and mixing. The second motor 113 drives the lifting screw 112 to rotate, and the lifting screw 112 drives the lifting frame 13 to move downward. The sprinkler head on the Z-shaped sprinkler pipe 33 is placed under the leaves of the wheat crop, and the mobile body 1 carries the sprinkler assembly 3 to move;

[0060] During the movement, the three-way valve 18 controls the fertilizer suction pipe 110 to communicate with the water pump 17. The water pump 17 extracts liquid fertilizer through the fertilizer suction pipe 110 and injects it into the trapezoidal liquid injection tank 32 through the liquid injection pipe 111. The liquid fertilizer solution is then sprayed to the diversion tank 31 through multiple liquid outlet pipes 35. The liquid fertilizer solution in the diversion tank 31 enters the Z-shaped sprinkler pipe 33 through the liquid outlet 37 and is then sprayed out through the corresponding sprinkler head. At the same time, the liquid fertilizer solution sprayed through the inclined liquid outlet pipe 35 prompts the multiple impellers 34 to rotate. The rotating impellers 34 cooperate with the liquid outlet 37 through the connecting block 38 and the auxiliary plate to prompt the multiple Z-shaped sprinkler pipes 33 to rotate synchronously, forming a circular spraying path, thereby eliminating the obstruction of the liquid fertilizer spraying caused by the roots and stems of the wheat crops.

[0061] Step 2: Flushing irrigation water sprinkler treatment, specifically the following steps: the three-way valve 18 controls the water suction pipe 19 to communicate with the water pump 17, the water pump 17 draws irrigation water through the water suction pipe 19, and then sprays it out through the sprinkler head, first draining the liquid fertilizer solution in the pipe, and then the second motor 113 drives the lifting screw 112 to rotate, and the lifting screw 112 drives the lifting frame 13 to move, placing the sprinkler head on the Z-shaped sprinkler pipe 33 above the leaves of the wheat crop, spraying the wheat crop with irrigation water, and at the same time flushing some of the liquid fertilizer splashed on the leaves;

[0062] By extending the telescopic rod of the electric push rod 115, the diversion chamber 31 is driven to deflect in the vertical direction, further adjusting the spraying height and expanding the spraying range. In the process of the deflection of the diversion chamber 31, the hinge connection between the auxiliary block and the U-shaped frame 114 is used to drive the movable plate 36 to move away from the diversion chamber 31. The movable plate 36 drives the multiple impellers 34 to move through the support plate, thereby reducing the contact degree with the water sprayed from the liquid outlet pipe 35 and avoiding increasing the water outlet resistance. In addition, the movement of the impeller 34 causes the liquid outlet 37 to expand, increase the water output, and improve the spraying range while ensuring that the spraying amount in each area remains unchanged.

[0063] As the water pump 17 draws irrigation water from the water tank 11, the internal pressure of the water storage chamber 14 decreases as the amount of irrigation water decreases. The water in the external pool is then drawn through the water pumping pipe on the retractable wheel 22 and the connecting pipe 16, thereby spraying a large amount of irrigation water. As the mobile body 1 moves, the first motor 24 drives the retractable wheel 22 to rotate, unwinding the wound water pumping pipe.

[0064] Step 3: The impurity-removing water pumping pipe winding link, the specific steps are as follows: After the sprinkler irrigation is completed, while the mobile body 1 moves, the first motor 24 drives the retracting wheel 22 to rotate, and the released water pumping pipe is retracted. The rotation of the retracting wheel 22 is coordinated with the sprocket 26 and the chain 27 to drive the reciprocating screw rod 25 to rotate, and the reciprocating screw rod 25 drives the guide sleeve 23 to reciprocate, and the retracted water pumping pipe is assisted to be evenly wound. The movement of the guide sleeve 23 causes the gear ring 28 engaged with the tooth plate 210 to carry the internal annular cleaning brush 29 to rotate, and the impurities on the surface of the retracted water pumping pipe are simultaneously cleaned.

[0065] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
