Description

Technical Field

[0001] This utility model relates to a drip irrigation system, specifically a drip irrigation system for intensive corn planting, and belongs to the field of agricultural planting technology. Background Technology

[0002] Drip irrigation is an irrigation method that delivers water to the roots of crops in a small flow rate through pipes via fine orifices or drippers for localized irrigation. It is the most effective water-saving irrigation method in arid and water-scarce areas, with a water utilization rate of up to 95%. Drip irrigation has a higher water-saving and yield-increasing effect than sprinkler irrigation, and can be combined with fertilization to more than double fertilizer efficiency. It is suitable for irrigating fruit trees, vegetables, cash crops, and greenhouses, and can also be used for field crop irrigation in arid and water-scarce areas.

[0003] However, when using drip irrigation in intensive corn planting, operators can only adjust the water outlets on the drip tubes one by one to control the water flow, which is inconvenient when the water requirements of corn change or the climate changes. Utility Model Content

[0004] The purpose of this invention is to provide a drip irrigation system for intensive corn planting in order to solve the above problems. Through the drip irrigation structure, the size of the openings on the drip irrigation pipe can be adjusted or the openings can be closed at the same time, which further improves the water-saving effect and enhances the flexibility of irrigation volume control, making it convenient to adjust the irrigation volume according to changes in crop water requirements.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a drip irrigation system for intensive corn planting, comprising a drip irrigation pipe, a drip irrigation structure on the drip irrigation pipe, the drip irrigation structure including a fixing sleeve, a plurality of fixing sleeves being fixedly connected to the drip irrigation pipe at equal intervals, a drip groove being formed on the inner side of the fixing sleeve of the drip irrigation pipe, a sliding sleeve being slidably connected to the inner side of the fixing sleeve, a sealing strip being fixedly connected to the middle of the sliding sleeve, the side of the sealing strip being slidably connected to the side of the drip irrigation pipe, a first fixing seat and a second fixing seat being fixedly connected to both ends of the drip irrigation pipe respectively, a pulley being rotatably connected to the bottom side of the first fixing seat, a traction rope being wound around the side of the pulley, one end of the traction rope being fixedly connected to a plurality of sliding sleeves in sequence, and an adjustment structure being provided on the inner side of the second fixing seat.

[0006] Preferably, the drip groove is formed on the bottom side of the drip irrigation pipe, and the bottom side of the fixing sleeve is provided with a leakage groove, and the drip groove and the leakage groove are provided in a one-to-one correspondence.

[0007] Preferably, the adjustment structure includes a winding wheel, and two winding wheels are rotatably connected to the bottom side of the second fixed base. The two ends of the traction rope are respectively fixedly connected to the middle of the two winding wheels, and the length of the traction rope is greater than twice the distance between the winding wheel and the pulley.

[0008] Preferably, a worm gear sleeve is rotatably connected to the take-up reel, and a worm is rotatably connected to the side of the second fixed seat, the side of the worm meshing with both worm gear sleeves simultaneously.

[0009] Preferably, the top of the worm gear sleeve has a first groove with a cross shape, and the top of the winding wheel has a second groove with a straight line shape.

[0010] Preferably, the top end of the worm gear sleeve is provided with a rotating block, the rotating block is slidably connected to the inner side of the second fixed seat, the inner side of the rotating block is slidably connected to a connecting block, a spring is fixedly connected between the connecting block and the rotating block, and the bottom end of the connecting block is engaged with the worm gear sleeve and the winding wheel through a first slot and a second slot respectively.

[0011] Preferably, the top of the rotating block is rotatably connected to an adjusting column, and the adjusting column is slidably connected to the top side of the second fixed seat.

[0012] Preferably, a rocker arm is rotatably connected to the middle of the second fixed base, and a limiting groove is provided at both ends of the rocker arm. The two ends of the rocker arm are slidably connected to the adjusting column provided on the same side through the limiting groove.

[0013] Preferably, a torsion spring is fixedly connected between the rocker arm and the second fixed seat, and the distance between the rocker arm's pivot and the two adjusting columns is equal.

[0014] The beneficial effects of this utility model are as follows: the sealing strip inside the fixed sleeve can seal the groove. When the sliding sleeve slides inside the fixed sleeve, the relative position between the sealing strip and the groove changes, thereby adjusting the size of the groove opening. In order to facilitate the simultaneous control of the effective length of all grooves opened on the drip irrigation pipe, all sliding sleeves are fixed on the traction rope. Therefore, by pulling the two ends of the traction rope, the sliding sleeve can be driven to slide in both directions inside the fixed sleeve, thereby controlling the drip volume. Since the drip irrigation pipe is relatively long, in order to facilitate the operation of the user, a pulley is provided in the first fixed seat at one end of the drip irrigation pipe. The middle part of the traction rope passes around the pulley, so that both ends of the traction rope are located at the second fixed seat position. At this time, the user only needs to be at the second fixed seat position to simultaneously control the drip volume, improving the flexibility of use. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-7As shown, a drip irrigation system for intensive corn planting includes a drip irrigation pipe 1, a drip irrigation structure 2 on the drip irrigation pipe 1, and a fixing sleeve 205. Multiple fixing sleeves 205 are sequentially and equidistantly fixedly connected to the drip irrigation pipe 1. A drip groove 209 is formed on the inner side of the fixing sleeve 205 of the drip irrigation pipe 1. A sliding sleeve 207 is slidably connected to the inner side of the fixing sleeve 205. A sealing strip 208 is fixedly connected to the middle of the sliding sleeve 207. The side of the sealing strip 208 is slidably connected to the side of the drip irrigation pipe 1. A first fixing seat 201 and a second fixing seat 202 are fixedly connected to both ends of the drip irrigation pipe 1, respectively. A pulley 204 is rotatably connected to the bottom side of the first fixing seat 201. A traction rope 203 is wound around the side of the pulley 204. One end of the traction rope 203 is sequentially fixedly connected to multiple sliding sleeves 207. An adjustment structure 3 is provided on the inner side of the second fixing seat 202.

[0025] As a technical optimization of this utility model, the drip groove 209 is opened on the bottom side of the drip irrigation pipe 1, and the bottom side of the fixing sleeve 205 is provided with a leakage groove 206. The drip groove 209 and the leakage groove 206 are arranged in a one-to-one correspondence. The drip groove 209 is opened on the bottom side of the fixing sleeve 205 and its length is the same as that of the leakage groove 206, which makes the control effect of dripping water better. At the same time, the edge of the drip groove 209 is a raised structure, which can better guide the leaked irrigation water and ensure that the irrigation water drips to the designated position.

[0026] As a technical optimization of this utility model, the adjusting structure 3 includes a winding wheel 302. Two winding wheels 302 are rotatably connected to the bottom side of the second fixed base 202. The two ends of the traction rope 203 are respectively fixedly connected to the middle of the two winding wheels 302. The length of the traction rope 203 is greater than twice the distance between the winding wheel 302 and the pulley 204. A worm gear sleeve 303 is rotatably connected to the winding wheel 302. A worm 301 is rotatably connected to the side of the second fixed base 202. The side of the worm 301 meshes with both worm gear sleeves 303. The top of the worm gear sleeve 303 has a cross-shaped first slot 308. The top of the winding wheel 302 has an I-shaped slot. The second slot 312 has a rotating block 304 at the top of the worm gear sleeve 303. The rotating block 304 is slidably connected to the inner side of the second fixed base 202. A connecting block 307 is slidably connected to the inner side of the rotating block 304. A spring 305 is fixedly connected between the connecting block 307 and the rotating block 304. The bottom end of the connecting block 307 is engaged with the worm gear sleeve 303 and the winding wheel 302 respectively through the first slot 308 and the second slot 312. An adjusting column 306 is rotatably connected to the top of the rotating block 304. The adjusting column 306 is slidably connected to the top side of the second fixed base 202. A rocker arm 309 is rotatably connected to the middle of the second fixed base 202. Limiting grooves 311 are respectively opened at both ends of the rocker arm 309. Both ends of the rocker arm 309 are slidably connected to the adjusting columns 306 on the same side via limiting grooves 311. A torsion spring 310 is fixedly connected between the rocker arm 309 and the second fixed base 202. The distance between the pivot of the rocker arm 309 and the two adjusting columns 306 is equal. To facilitate user adjustment of the water volume using the traction rope 203 and improve the accuracy of water volume adjustment, two winding wheels 302 are provided on the bottom side of the second fixed base 202. Both ends of the traction rope 203 are fixedly connected to the two winding wheels 302. The length of the traction rope 203 is greater than twice the distance between the pulley 204 and the winding wheel 302, thus ensuring that when either of the two winding wheels 302 rotates while the traction rope 203 is taut. This allows the traction rope 203 to slide and retract, thereby adjusting the irrigation volume. The retractor 302 is equipped with a worm gear sleeve 303. During adjustment, the user first needs to press the adjusting post 306 on the second fixed base 202 according to the desired adjustment effect, i.e., the retracting direction of the traction rope 203. By default, due to the torsion spring 310 connecting the lever 309 and the second fixed base 202, the height of one adjusting post 306 is lower than the other. The lower adjusting post 306 is located on the same plane as the drip irrigation pipe 1. At this time, the connecting block 307 inside the bottom rotating block 304 of the adjusting post 306 will simultaneously engage with the corresponding worm gear sleeve 303 and retractor 302 through the first slot 308 and the second slot 312.Due to the action of the rocker arm 309, the locking block on the other side will be disengaged from the corresponding worm gear sleeve 303 and take-up reel 302. When the user presses the adjusting column 306 on the other side, the adjusting column 306 on the other side will be lifted by the rotation of the rocker arm 309. At the same time, the adjusting column 306 slides inward toward the second fixed seat 202. The rotating block 304 at the bottom of the adjusting column 306 slides at the same time and applies pressure to the connecting block 307 on the inner side. If the worm gear sleeve 303 starts to rotate at this time, it can guide the connecting block 307 to finally engage with the corresponding worm gear sleeve 303 and take-up reel 302 through the first locking groove 308 and the second locking groove 312. In both of these cases, regardless of whether the user presses the adjusting column 306, the adjusting column 306 will be lifted by the rotation of the rocker arm 309. Pressing down the adjusting column 306 on one side causes the worm gear 301 to rotate. The worm gear 301 then simultaneously drives the two meshing worm wheel sleeves 303 to rotate synchronously. Based on the engagement state between the corresponding connecting block 307, the worm wheel sleeve 303, and the corresponding winding wheel 302, one of the winding wheels 302 is driven. Due to the rocker arm 309, only one side of the worm wheel sleeve 303 rotates simultaneously via the connecting block 307 and the winding wheel 302. This allows for simultaneous control of the opening length of all the drainage channels 206 on the drip irrigation pipe 1 via the traction rope 203, improving ease of use and enabling more precise adjustment of the irrigation volume through the worm gear 301's adjustment effect.

[0027] In use, this invention firstly includes multiple fixed sleeves 205 on the drip irrigation pipe 1. A drainage groove 206 for irrigation water outflow is located inside the fixed sleeve 205. A sealing strip 208 inside the fixed sleeve 205 seals the drainage groove 206. When the sliding sleeve 207 slides within the fixed sleeve 205, the relative position of the sealing strip 208 and the drainage groove 206 changes, thus adjusting the size of the opening in the drainage groove 206. A drip groove 209 is located on the bottom side of the fixed sleeve 205 and has the same length as the drainage groove 206, resulting in better control of the drip volume. Furthermore, the edge of the drip groove 209 has a raised structure, which better guides the leaked irrigation water, ensuring the irrigation water drips smoothly. The drip irrigation pipe 1 is positioned at the designated location. To facilitate simultaneous control of the effective length of all the slots 206 on the drip irrigation pipe 1, all sliding sleeves 207 are fixed to the traction rope 203. Therefore, by pulling the two ends of the traction rope 203, the sliding sleeves 207 can be moved to slide in both directions within the fixed sleeve 205, thereby controlling the drip volume. Due to the relatively large length of the drip irrigation pipe 1, a pulley 204 is installed in the first fixed seat 201 at one end of the drip irrigation pipe 1 for user convenience. The middle part of the traction rope 203 passes over the pulley 204, so that both ends of the traction rope 203 are located at the second fixed seat 202. At this time, the user only needs to be at the second fixed seat 202 to simultaneously control the drip volume. The amount of water dripped is adjusted. Furthermore, to facilitate user adjustment of the water volume using the traction rope 203 and improve the accuracy of water volume control, two winding wheels 302 are located on the bottom side of the second fixed base 202. Both ends of the traction rope 203 are fixedly connected to the two winding wheels 302. The length of the traction rope 203 is greater than twice the distance between the pulley 204 and the winding wheels 302. This ensures that when either of the two winding wheels 302 rotates while the traction rope 203 is taut, it can slide and wind up, thus adjusting the water volume. A worm gear sleeve 303 is provided on the winding wheel 302. During adjustment, the user first needs to... According to the expected adjustment effect, that is, the winding direction of the traction rope 203 is pressed to adjust the adjusting column 306 on the second fixed seat 202. By default, due to the torsion spring 310 connecting the rocker arm 309 and the second fixed seat 202, the height of one adjusting column 306 is lower than that of the other. The adjusting column 306 with the lower height is located on the same plane as the drip irrigation pipe 1. At this time, the connecting block 307 in the bottom rotating block 304 of the adjusting column 306 will engage with the corresponding worm gear sleeve 303 and winding wheel 302 through the first slot 308 and the second slot 312. Due to the action of the rocker arm 309, the locking block on the other side will be disengaged from the corresponding worm gear sleeve 303 and winding wheel 302.When the user presses the other adjusting column 306, the other adjusting column 306 is first lifted by rotating the rocker arm 309. At the same time, the current adjusting column 306 slides inward toward the second fixed seat 202. The rotating block 304 at the bottom of the adjusting column 306 slides simultaneously and applies pressure to the inner connecting block 307. If the worm gear sleeve 303 starts to rotate at this time, it can guide the connecting block 307 to finally engage with the corresponding worm gear sleeve 303 and winding wheel 302 through the first slot 308 and the second slot 312. In both cases, regardless of whether the user presses the adjusting column 306 on one side, after rotating the worm gear 301... The worm gear 301 simultaneously drives the two meshing worm gear sleeves 303 to rotate synchronously. Then, based on the engagement state between the corresponding connecting block 307, the worm gear sleeve 303, and the corresponding winding wheel 302, one of the winding wheels 302 is driven. Due to the rocker arm 309, only one side of the worm gear sleeve 303 rotates through the connecting block 307 and the winding wheel 302 at a time. This allows for simultaneous control of the opening length of all the slots 206 on the drip irrigation pipe 1 via the traction rope 203, improving ease of use and enabling more precise adjustment of the irrigation volume through the adjustment effect of the worm gear 301.
