Description

Technical Field

[0001] The present invention relates to the technical field of soil improvement, and specifically provides an irrigation device and an irrigation method for improving saline-alkali soil in the Yellow River Delta region. Background Technique

[0002] Soil improvement refers to the process of improving the physical, chemical, and biological properties of soil through a series of measures and technical means to enhance its fertility and productivity. The saline-alkali soil in the Yellow River Delta region generally has problems such as high salt content, strong alkalinity, and loose structure. These soil characteristics pose severe challenges to agricultural production, and it is necessary to improve these saline-alkali soils. Irrigation is an important measure in saline-alkali soil improvement. Through irrigation, the dissolved salts can be effectively flushed to the deep layer of the soil, reducing the degree of salinization on the soil surface. It can also provide the water required for crop growth and promote the normal growth of crops.

[0003] In the prior art, when the saline-alkali soil in the Yellow River Delta region is improved on a large scale, sprinkler irrigation is mostly used, which can quickly moisten the soil surface. During the use of the irrigation device, the height of the sprinkler head for sprinkler irrigation is usually fixed and can only spray water at one height. When the terrain of the sprinkler irrigation area is uneven with undulations, the sprinkler irrigation will be uneven, resulting in more water spraying in some local soil areas and insufficient water spraying in some local soil areas, thus affecting the soil improvement effect.

[0004] Therefore, we propose an irrigation device and an irrigation method for improving saline-alkali soil in the Yellow River Delta region to solve the problems raised in the above background technique. Summary of the Invention

A plurality of drain holes are formed in the outer surface of the adjusting sleeve near the drain cover.

[0017] A method for using an irrigation device for improving saline-alkali soil in the Yellow River Delta region includes the following steps:

[0018] S1. Turn the four threaded shafts to pull the four limiting rods out of the limiting grooves. Then start the forward and reverse motor to drive the rotation of the rotating gear, the annular gear sleeve and the adjusting sleeve, and drive the water distributor to rotate inside the water spraying cover through the arc-shaped rod and the fixed rod;

[0019] S2. At the same time, the adjusting sleeve rotates upward inside the two arc-shaped threaded sleeves to push the I-shaped sleeve upward and increase the height of the water spraying cover. Then the output end of the forward and reverse motor will automatically rotate in the reverse direction to drive the adjusting sleeve to rotate downward in a spiral manner and gradually reduce the height of the water spraying cover. Driven by the forward and reverse motor, the water spraying cover can move up and down while rotating and spraying water to adjust the height;

[0020] S3. Start the water pump. The external water source is filtered through the filter, and then is sequentially transported to the water spraying pipe and the telescopic pipe through the water supply pipe and the connecting pipe. The water is divided into multiple water streams through the multiple water spraying holes and is sprayed upward at high speed. The rotating water distributor sprays the sprayed water streams outward;

[0021] S4. When the water spraying cover reaches the appropriate height, pause the forward and reverse motor, insert the limiting rod into the threaded hole at the corresponding position, then rotate the threaded shaft in the reverse direction so that one end of the limiting rod is inserted into the limiting groove, and then rotate the threaded rod to pull the arc-shaped threaded sleeve outward through the T-shaped block so that the arc-shaped threaded sleeve is separated from the adjusting sleeve. The forward and reverse motor can drive the water distributor to rotate and spray water at the fixed position.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. When the present invention is in use, turn the four threaded shafts to pull out the four limit rods from the inside of the limit grooves. Then start the forward and reverse motor to drive the rotation of the rotating gear, the annular gear sleeve and the adjusting sleeve. Drive the water sprinkler to rotate inside the water spray cover through the arc-shaped rod and the fixed rod. At the same time, the adjusting sleeve rotates upward inside the two arc-shaped threaded sleeves, pushing the I-shaped sleeve upward to increase the height of the water spray cover. Then the output end of the forward and reverse motor will automatically rotate in the reverse direction, driving the adjusting sleeve to rotate downward in a spiral manner, gradually reducing the height of the water spray cover. With the cooperation of the irrigation component and the adjustment component, it can realize the functions of moving up and down, adjusting different heights and rotating the water spray. Both the water spray area and the water spray angle are adjusted. Even if the local soil is uneven, water can be evenly sprayed, greatly increasing the water spray range, which is beneficial to evenly distribute water throughout the irrigation area and improve the utilization rate of water, effectively avoiding uneven water spraying.

[0024] 2. When the present invention is in use, when the water spray cover reaches the appropriate height, pause the forward and reverse motor, insert the limit rod into the threaded hole and the movable hole at the corresponding position, and then rotate the threaded shaft in the reverse direction so that one end of the limit rod is inserted into the limit groove to limit the adjusting sleeve. Then rotate the threaded rod, pull the arc-shaped threaded sleeve outward through the T-shaped block, so that the arc-shaped threaded sleeve is separated from the adjusting sleeve. Under the action of the height fixing component, the effect of adjusting and fixing the height of the water spray cover is achieved. Start the forward and reverse motor again, and at this time it will drive the adjusting sleeve to rotate forward and backward, so that the water spray cover rotates and sprays water at the fixed height position, so that the soil in this range can be sprayed water targeted.

[0025] 3. When the present invention is in use, start the water pump, the external water source is filtered through the filter, and then sequentially transported to the water spray pipe and the telescopic pipe through the water delivery pipe and the connecting pipe. The water is divided into multiple water flows through multiple water spray holes and sprayed upward at high speed. The rotating water sprinkler sprays the sprayed water flow outward, so as to irrigate the saline-alkali soil. When part of the water flow flows into the adjusting sleeve, the waterproof cover guides the water flow to the drainage hole, and the water is discharged to the outside through the drainage cover, playing a protective role.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] Embodiment 1: Please refer to Figures 1 - 9 As shown in the figure, the present invention provides a technical solution: an irrigation device for improving saline-alkali soil in the Yellow River Delta region, including an irrigation component 1, with an adjustment component 2 and a height fixing component 3 arranged on the top of the irrigation component 1; the adjustment component 2 includes a fixed seat 201, a mounting seat 202 is fixedly installed near the inner wall at the top of the fixed seat 201, a positive and negative motor 203 is fixedly installed inside the mounting seat 202, a rotating gear 204 is fixedly installed at the output end of the positive and negative motor 203, an annular gear sleeve 205 is sleeved on the outer surface of the positive and negative motor 203, an adjustment sleeve 206 is fixedly installed on the outer surface of the annular gear sleeve 205, an arc-shaped rod 208 is fixedly installed at the top of the adjustment sleeve 206, a fixed rod 209 is fixedly installed on the outer surface of the arc-shaped rod 208, a water distributor 210 is fixedly installed at the bottom end of the fixed rod 209, and two arc-shaped threaded sleeves 207 are meshed and connected to the outer surface of the adjustment sleeve 206; the height fixing component 3 includes a fixed cover 301, a plurality of threaded holes 302 are equidistantly opened on the outer surface of the fixed cover 301, threaded shafts 303 are threadedly embedded in the internal of four of the threaded holes 302, a limiting rod 304 is fixedly installed at one end of each of the four threaded shafts 303, two fastening holes 305 are opened near the top on the outer surface of the fixed cover 301, threaded rods 306 are threadedly embedded in the internal of the two fastening holes 305, a T-shaped block 307 is fixedly installed at one end of each of the two threaded rods 306, a limiting ring 308 is fixedly installed near the bottom on the outer surface of the adjustment sleeve 206, a limiting groove 309 is opened on the outer surface of the limiting ring 308, one end of each of the four limiting rods 304 is movably embedded in the internal of the limiting groove 309, T-shaped grooves 215 are opened near the top on the outer surface of each of the two arc-shaped threaded sleeves 207, a plurality of moving holes 216 are equidistantly opened on the outer surface of each of the two arc-shaped threaded sleeves 207, one end of each of the four limiting rods 304 is movably embedded in the internal of four of the moving holes 216 respectively, and the outer surface of each of the two T-shaped blocks 307 is movably embedded in the internal of the two T-shaped grooves 215 respectively, the bottom of the fixed cover 301 is fixedly installed on the top of the fixed seat 201, and both of the two arc-shaped threaded sleeves 207 are located inside the fixed cover 301.

[0039] In this embodiment, during use, the four threaded shafts 303 are respectively rotated to rotate outwards in the corresponding threaded holes 302, driving the four limiting rods 304 to rotate outwards in the corresponding moving holes 216, so that one ends of the four limiting rods 304 all rotate out from inside the limiting grooves 309. At this time, the limiting ring 308 loses its limit, and the outer surface of the limiting ring 308 does not contact the inner walls of the two arc-shaped threaded sleeves 207. Then, the forward and reverse motor 203 is started, and the rotation of the output end of the forward and reverse motor 203 drives the rotating gear 204 to rotate, further driving the annular gear sleeve 205 and the adjusting sleeve 206 to rotate, and driving the arc-shaped rod 208 and the fixed rod 209 to rotate together, further driving the water sprinkler 210 to rotate inside the water spraying cover 108, spraying the multiple water flows ejected from the water spraying holes 110 outwards, so as to achieve the effect of rotary irrigation and expand the water spraying range. The two arc-shaped threaded sleeves 207 are threadedly connected to the adjusting sleeve 206, so that the adjusting sleeve 206 rotates upwards inside the two arc-shaped threaded sleeves 207, jacking up the I-shaped sleeve 111, thereby jacking up the water spraying cover 108 and gradually increasing the height of the water spraying cover 108. In addition, after the telescopic sleeve 109 and the telescopic pipe 107 are subjected to tensile force, they will gradually expand and do not affect the upward movement of the water spraying cover 108. When the adjusting sleeve 206 moves to the highest position, the output end of the forward and reverse motor 203 will automatically rotate in the reverse direction, driving the rotating gear 204 and the annular gear sleeve 205 to rotate in the reverse direction. At the same time, the adjusting sleeve 206 rotates spirally downwards, driving the I-shaped sleeve 111 and the water spraying cover 108 to move downwards together, thereby gradually reducing the height of the water spraying cover 108. Through the forward and reverse rotation of the forward and reverse motor 203, the adjusting sleeve 206 and the water spraying cover 108 are driven to continuously move up and down. With the cooperation of the irrigation assembly 1 and the adjusting assembly 2, the functions of moving up and down, adjusting different heights and rotating for water spraying can be realized. The water spraying area and the water spraying angle are both adjusted. Even if the local soil is uneven, water can be evenly sprayed, greatly increasing the water spraying range, being beneficial to evenly distributing water throughout the irrigation area, improving the utilization rate of water, and effectively avoiding uneven water spraying. It solves the problem that during the use of the irrigation device for improving saline-alkali soil in the Yellow River Delta region, the nozzle usually can only spray water at a single height. When the terrain of the irrigated area is uneven with undulations, the irrigation will be uneven, affecting the soil improvement effect.

[0040] Embodiment 2: As Figures 2 - 3 and Figures 5 - 9As shown, an adjustment component 2 and a height fixing component 3 are arranged on the top of the water filling component 1. The height fixing component 3 includes a fixing cover 301. A plurality of threaded holes 302 are equidistantly arranged on the outer surface of the fixing cover 301. Threaded shafts 303 are threadedly embedded in the interiors of four of the threaded holes 302. Limit rods 304 are fixedly installed at one ends of the four threaded shafts 303. Two fastening holes 305 are arranged on the outer surface of the fixing cover 301 near the top. Threaded rods 306 are threadedly embedded in the interiors of the two fastening holes 305. T-shaped blocks 307 are fixedly installed at one ends of the two threaded rods 306. A limit ring 308 is fixedly installed on the outer surface of the adjustment sleeve 206 near the bottom. A limit groove 309 is arranged on the outer surface of the limit ring 308. One ends of the four limit rods 304 are movably embedded in the interior of the limit groove 309. T-shaped grooves 215 are arranged on the outer surfaces of the two arc-shaped threaded sleeves 207 near the top. A plurality of movable holes 216 are equidistantly arranged on the outer surfaces of the two arc-shaped threaded sleeves 207. The outer surfaces of the four limit rods 304 are respectively movably embedded in the interiors of four of the movable holes 216. The outer surfaces of the two T-shaped blocks 307 are respectively movably embedded in the interiors of the two T-shaped grooves 215. The bottom of the fixing cover 301 is fixedly installed on the top of the fixing seat 201. The two arc-shaped threaded sleeves 207 are both located inside the fixing cover 301.

[0041] In this embodiment, during use, when it is necessary to spray water on a certain soil area specifically, the forward and reverse motor 203 is driven to make the adjusting sleeve 206 rotate spirally upward in the two arc-shaped threaded sleeves 207, and drive the limit ring 308 to rotate upward inside the two arc-shaped threaded sleeves 207. When the water spraying cover 108 reaches the appropriate height, the forward and reverse motor 203 is paused. Then, the four threaded shafts 303 are screwed out from the threaded holes 302 at the bottom, and the corresponding limit rods 304 are pulled out from the movable holes 216 and the threaded holes 302. Then, according to the height position of the limit ring 308, the limit rods 304 are inserted into the threaded holes 302 and the movable holes 216 at the corresponding positions. At this time, the threaded shafts 303 move to the threaded holes 302 at the corresponding positions. Then, the threaded shafts 303 are rotated in the reverse direction, so that one end of the limit rod 304 is inserted into the limit groove 309, thereby performing limit support on the limit ring 308 after the adjustment position, that is, limiting the adjusting sleeve 206. Then, the threaded rod 306 is rotated to make it rotate spirally outward in the fastening hole 305, further driving the T-shaped block 307 to rotate in the T-shaped groove 215. As the threaded rod 306 moves outward, the T-shaped block 307 pulls the arc-shaped threaded sleeve 207 to move outward, so that the arc-shaped threaded sleeve 207 is separated from the adjusting sleeve 206, and at the same time, the distance between the arc-shaped threaded sleeve 207 and the fixed cover 301 is shortened. Repeat the above operation process to separate the other arc-shaped threaded sleeve 207 from the adjusting sleeve 206. At this time, the limit ring 308 and the limit rod 304 cooperate to limit the adjusting sleeve 206, and there is no contact between the adjusting sleeve 206 and the arc-shaped threaded sleeve 207. Under the action of the height fixing component 3, the effect of adjusting and fixing the height of the water spraying cover 108 is achieved. The forward and reverse motor 203 is started again. At this time, it will drive the adjusting sleeve 206 to rotate forward and backward, so that the water spraying cover 108 rotates and sprays water at the fixed height position, so that the soil in this range can be sprayed water specifically. The limit groove 309 is arranged in a ring shape and does not affect the rotation of the limit ring 308.

[0042] Embodiment 3: As Figures 1 - 6 and Figure 9As shown, the irrigation component 1 includes a water pump 101. A filter 102 is provided on the outer surface of the water pump 101. The input end of the filter 102 is connected to a water suction pipe 103 through a flange. The output end of the filter 102 is connected to a water supply pipe 104 through a flange. One end of the water supply pipe 104 is connected to the input end of the water pump 101 through a flange. The output end of the water pump 101 is connected to a connecting pipe 105 through a flange. A fixing seat 201 is fixedly installed on the top of the connecting pipe 105. A spray pipe 106 is fixedly connected to the top of the connecting pipe 105. One end of the spray pipe 106 is fixedly connected to a telescopic pipe 107. One end of the telescopic pipe 107 is fixedly connected to a spray hood 108. A telescopic sleeve 109 is movably sleeved on the outer surface of the spray hood 108. A plurality of spray holes 110 are formed in the bottom surface inside the spray hood 108. The top of the telescopic sleeve 109 is fixedly connected to the bottom of the spray hood 108. The bottom of the telescopic sleeve 109 is fixedly connected to the top end of the spray pipe 106. The outer surface of the spray pipe 106 is located inside the fixing seat 201. The outer surface of a rotating gear 204 meshes with the inside of an annular gear sleeve 205. A water distributor 210 is movably embedded in the spray hood 108. A ball 217 is movably embedded in the bottom of the water distributor 210. The outer surface of the ball 217 contacts the bottom surface inside the spray hood 108. An I-shaped sleeve 111 is fixedly installed on the outer surface of the spray hood 108 near the top. The outer surface of the I-shaped sleeve 111 is movably embedded in the inside of an adjusting sleeve 206. A waterproof cover 211 is fixedly installed near the top surface inside the adjusting sleeve 206. A drainage cover 212 is fixedly installed near the top of the outer surface of the adjusting sleeve 206. A sealing ring 213 is fixedly connected to the top of the waterproof cover 211. The top of the sealing ring 213 contacts the bottom of the I-shaped sleeve 111. The inner wall of the sealing ring 213 contacts the outer surface of the spray hood 108. A plurality of drainage holes 214 are formed in the outer surface of the adjusting sleeve 206 near the drainage cover 212.

[0043] In this embodiment, during use, one end of the water suction pipe 103 is connected to an external water source. The water pump 101 is started to pump the external water source into the filter 102 for filtration. Then, the filtered water is sequentially conveyed to the spray pipe 106 and the telescopic pipe 107 through the water delivery pipe 104 and the connecting pipe 105. The water is divided into multiple water streams through a plurality of spray holes 110 and sprayed upward at high speed. Driven by the adjusting assembly 2, the water distributor 210 rotates forward and backward inside the spray hood 108, and the sprayed water flows outward along the spiral track of the water distributor 210, thereby performing sprinkler irrigation on the saline-alkali soil. When the adjusting assembly 2 drives the water distributor 210 to rotate forward and backward, it can also drive the spray hood 108 to move up and down. The sealing ring 213 in the adjusting assembly 2 contacts the bottom of the I-shaped sleeve 111, improving the sealing performance between the waterproof cover 211 and the I-shaped sleeve 111. When part of the water flows in along the gap between the I-shaped sleeve 111 and the adjusting sleeve 206, under the protection of the waterproof cover 211, the water flow can be guided to the drain hole 214, and then the water is discharged to the outside through the drain hole 214 and the drain hood 212, thus playing a protective role and preventing part of the water flow from flowing into the inside of the adjusting sleeve 206 along the gap between the I-shaped sleeve 111 and the adjusting sleeve 206, affecting the normal operation of the forward and reverse motor 203.

[0044] The usage method and working principle of the present invention are as follows: Turn the four threaded shafts 303 to pull out the limit rod 304 from the inside of the limit groove 309. Start the forward and reverse motor 203 to drive the rotating gear 204 to rotate, further drive the annular gear sleeve 205 and the adjusting sleeve 206 to rotate, and drive the arc rod 208 and the fixed rod 209 to rotate together, further drive the water sprinkler 210 to rotate inside the water spraying cover 108. Under the threaded connection of the two arc-shaped threaded sleeves 207, the adjusting sleeve 206 rotates upward inside the two arc-shaped threaded sleeves 207, jacks up the I-shaped sleeve 111, thereby jacks up the water spraying cover 108 and gradually increases the height of the water spraying cover 108. When the adjusting sleeve 206 moves to the highest position, the output end of the forward and reverse motor 203 will automatically rotate in the reverse direction, drive the rotating gear 204 and the annular gear sleeve 205 to rotate in the reverse direction, and at the same time the adjusting sleeve 206 rotates downward in a spiral manner, driving the I-shaped sleeve 111 and the water spraying cover 108 to move downward together, thereby gradually reducing the height of the water spraying cover 108. Through the forward and reverse rotation of the forward and reverse motor 203, the adjusting sleeve 206 and the water spraying cover 108 are driven to continuously move up and down. Start the water pump 101 to pump the external water source into the filter 102 for filtration, and then sequentially transport the filtered water to the spray water pipe 106 and the telescopic pipe 107 through the water delivery pipe 104 and the connecting pipe 105. The water is divided into multiple water streams through multiple water spraying holes 110 and sprayed upward at a high speed, and sprayed outward along the spiral track of the water sprinkler 210, thereby performing sprinkler irrigation on the saline-alkali soil. When part of the water flow flows in along the gap between the I-shaped sleeve 111 and the adjusting sleeve 206, under the protection of the waterproof cover 211, the water flow can be guided to the drain hole 214, and then the water is discharged to the outside through the drain hole 214 and the drain cover 212, thereby playing a protective role and preventing part of the water flow from flowing into the inside of the adjusting sleeve 206 along the gap between the I-shaped sleeve 111 and the adjusting sleeve 206 and affecting the normal operation of the forward and reverse motor 203. When the water spraying cover 108 reaches the appropriate height, pause the forward and reverse motor 203, and according to the height position of the limit ring 308, insert the limit rod 304 into the threaded hole 302 and the movable hole 216 at the corresponding position. At this time, the threaded shaft 303 moves to the threaded hole 302 at the corresponding position, and then reverse-rotate the threaded shaft 303 so that one end of the limit rod 304 is inserted into the limit groove 309, thereby performing limit support on the adjusted limit ring 308, that is, limiting the adjusting sleeve 206. Then rotate the threaded rod 306 to rotate it spirally outward in the fastening hole 305, further drive the T-shaped block 307 to rotate in the T-shaped groove 215. As the threaded rod 306 moves outward, the T-shaped block 307 pulls the arc-shaped threaded sleeve 207 to move outward, separating the arc-shaped threaded sleeve 207 from the adjusting sleeve 206. Start the forward and reverse motor 203 again. At this time, it will drive the adjusting sleeve 206 to rotate forward and backward, so that the water spraying cover 108 rotates and sprays water at the fixed height position, thereby spraying water on the soil in this range in a targeted manner.

[0045] Among them, the water pump 101, the filter 102, and the forward and reverse motor 203 are all prior arts, and their components and operating principles are all publicly known technologies, and will not be elaborated here.

[0046] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
