A water-saving drip irrigation device for cotton planting

Abstract

This utility model relates to a water-saving drip irrigation device for cotton planting, comprising a head hub, a main pipe, a branch pipe, and a belt body that are sequentially sealed and connected. The belt body has an installation groove for mounting patches. Each patch includes a patch box with an inlet, an outlet, an insertion hole, and a groove. A patch cover is located within the groove, and a baffle is fixed to the patch cover. A connecting rod is fixedly connected to the baffle, and a pressing plate is fixedly connected to the connecting rod. A rubber pad is provided between the pressing plate and the patch box. By pressing and releasing the pressing plate, and with the rubber pad deforming and returning to its original position, the connecting rod, baffle, and patch cover are indirectly moved repeatedly. This not only allows the edge of the insertion hole to scrape the outside of the baffle but also changes the internal spatial structure of the patch box, thereby allowing impurities inside the patch to be discharged with the water flow, enhancing the cleaning effect and reducing residue.

Description

Technical Field

[0001] This utility model belongs to the field of drip irrigation device technology, specifically relating to a water-saving drip irrigation device for cotton planting. Background Technology

[0002] Cotton is an important economic crop. Its fiber is the main raw material for the textile industry, and its seeds can be used for oil extraction. It has extremely high economic value and a wide range of applications. In the planting process, it is necessary to formulate technical points based on local climate, soil conditions and the growth characteristics of cotton, which prefers warmth, light, and drought but requires concentrated water. Therefore, drip irrigation devices are required.

[0003] Cotton drip irrigation system is a complete irrigation system from water source to crop roots in the field. Its structure needs to be adapted to the characteristics of cotton, such as "wide spacing between plants and rows, water demand concentrated in the root layer, and multiple irrigations required during the growth period". It mainly consists of three parts: headworks, water distribution network, and field drip irrigation system.

[0004] Drip irrigation tape is the core component of the system, and its structural design directly affects irrigation efficiency, anti-clogging ability and service life. Different types of drip irrigation tape have slightly different structures, among which the patch-type drip irrigation tape is the most widely used.

[0005] The drip nozzles (patches) of patch-type drip irrigation tapes are usually formed by injection molding into tiny channels (with diameters mostly between 0.5 and 2 mm). The internal structure is relatively fine (such as a labyrinthine channel). Although this design can precisely control the flow rate, when the water quality is poor or the water contains a lot of impurities, the narrow channels are indeed easily occupied by impurities or sediments, leading to blockage and affecting the irrigation effect. To address this issue, we have proposed a water-saving drip irrigation device for cotton cultivation. Utility Model Content

[0006] The purpose of this invention is to provide a water-saving drip irrigation device for cotton planting, which solves the problems existing in the background art.

[0007] To achieve the above technical objectives, the technical solution adopted by this utility model is as follows:

[0008] A water-saving drip irrigation device for cotton cultivation includes a headworks, a main pipe, branch pipes, and drip irrigation tape that are sequentially and sealed together.

[0009] The headworks are used to process, pressurize, and regulate the water flow;

[0010] The main pipe, the branch pipe, and the drip irrigation tape are all used for transporting water.

[0011] The drip irrigation tape includes:

[0012] The belt body is connected to the branch pipe;

[0013] A plurality of patches are provided, and a plurality of mounting grooves are formed on the surface of the tape body, and each patch is mounted inside the tape body through each of the mounting grooves.

[0014] The patch includes:

[0015] The patch box is fitted to the inside of the tape body. The patch box has a water inlet on its side and a water outlet on its side facing the outside, which is opposite to the water inlet. The patch box has several insertion holes on its side away from the inner wall of the tape body, and the insertion holes are arranged alternately.

[0016] The patch cover has a groove at one end of the patch box away from the inner wall of the tape, and the patch cover is disposed inside the groove;

[0017] Several baffles, each of which is fixedly connected to the patch cover and passes through the corresponding insertion hole and abuts against the inner wall of the patch box;

[0018] Two connecting rods, one end of each connecting rod being fixedly connected to the two baffles that are furthest apart;

[0019] The pressing plate is fixedly connected to the other end of the two connecting rods;

[0020] A rubber pad is disposed between the pressing sheet and the patch box.

[0021] Further specified, any of the aforementioned insertion holes slides against the outer wall of the baffle.

[0022] Furthermore, the patch box is provided with a filter screen on its outer side, and the filter screen is located at the water inlet.

[0023] Furthermore, the filter screen is configured as an arc shape that convexes from the inside out in the patch box.

[0024] Furthermore, the patch cover is symmetrically beveled on both sides.

[0025] Further, the patch box has a protective frame at the external end, and the pressing pad and the rubber pad are both located inside the protective frame.

[0026] The beneficial effects of this utility model are:

[0027] 1. Through the linkage structure of the pressing plate, connecting rod, and rubber pad, the baffle reciprocates when the operator presses or releases the pressing plate, causing the channel inside the patch box to switch between a maze shape and a rectangle. Compared with a fixed flow channel, this facilitates the discharge of impurities with the water flow and enhances the cleaning effect.

[0028] 2. The labyrinthine channel formed by the staggered baffles inside the patch box can disrupt the water flow, reduce water pressure, and reduce the accumulation of impurities compared to traditional fine channels. At the same time, the sliding contact between the baffles and the sockets can scrape off attached impurities as the baffles move, enhancing the cleaning effect.

[0029] 3. By setting an arc-shaped protruding filter screen at the water inlet of the patch box, compared with the existing micro-channel structure, the filtration area can be increased, impurities can be reduced, and filtration efficiency and water flow stability can be improved.

[0030] 4. The beveled design on both sides of the patch cover, combined with water pressure and the rebound force of the rubber pad, makes the baffle reset faster and more stable. Compared with the non-guided structure, it improves the efficiency and reliability of channel restoration after cleaning. Attached Figure Description

[0042] Filter screen 200, protective frame 201. Detailed Implementation

[0043] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0044] like Figures 1-8 As shown, a water-saving drip irrigation device for cotton cultivation includes a headworks, a main pipe, branch pipes, and drip irrigation tape that are sequentially and sealed together.

[0045] The headworks are used to process, pressurize, and regulate the water flow;

[0046] Main pipes, branch pipes, and drip irrigation tape are all used to transport water.

[0047] Drip irrigation tape includes:

[0048] Belt body 100, which is connected to the branch pipe;

[0049] Several patches are provided, and several mounting slots 101 are formed on the surface of the tape body 100. Each patch is installed inside the tape body 100 through each mounting slot 101.

[0050] The patch includes:

[0051] The patch box 102 is fitted inside the tape body 100. The patch box 102 has a water inlet 103 on its side and a water outlet 104 on its side facing the outside, which is opposite to the water inlet 103. The patch box 102 has several holes 105 on its side away from the inner wall of the tape body 100, and the holes 105 are arranged alternately.

[0052] The patch cover 106 and the patch box 102 have a groove 107 at one end away from the inner wall of the tape body 100, and the patch cover 106 is located inside the groove 107;

[0053] Several baffles 108 are fixedly connected to the patch cover 106, and one end of each baffle passes through the corresponding insertion hole 105 and abuts against the inner wall of the patch box 102.

[0054] Two connecting rods 109, one end of each connecting rod 109 is fixedly connected to the two farthest baffles 108 respectively;

[0055] Pressing plate 110 is fixedly connected to the other end of the two connecting rods 109;

[0056] Rubber pad 111 is located between pressing plate 110 and patch box 102.

[0057] The head unit processes the water flow, such as filtering impurities, pressurizing the water to ensure it reaches each drip irrigation location, and regulating the irrigation time and volume, providing the required water flow for the entire drip irrigation system.

[0058] The main pipe is responsible for delivering the water, after it has been treated at the headworks, to various areas of the field. The branch pipes, on the other hand, branch off from the main pipes and deliver the water to more specific planting areas, eventually connecting to the drip irrigation belt, thus playing the role of delivering water in stages.

[0059] The tape body 100, connected to the branch pipe, is the main water delivery channel in the drip irrigation process, used to guide the water delivered from the branch pipe to each patch.

[0060] The drip patch is a key component for achieving precision drip irrigation. Through its internal structure, it drips water from the outlet at an appropriate flow rate and in an appropriate manner, acting on the cotton root zone.

[0061] The mounting groove 101 is formed on the surface of the tape body 100 to provide a mounting position for the patch, so that the patch can be stably installed inside the tape body 100 and ensure the orderly progress of the drip irrigation process;

[0062] After the patch is placed into the tape body 100 through the mounting groove 101, the patch is tightly fixed to the tape body 100 near the opening of the mounting groove 101 by means of hot melt process or special adhesive, so as to ensure the sealing and structural stability of the connection part.

[0063] The patch box 102 is the main support structure for the patch; the water inlet 103 on the side is used to receive water from the tape body, and the water outlet 104 facing the outside discharges water, providing a flow path for the water.

[0064] The opening direction of the inlet 103 is the same as the direction of water flow in the conveyor belt 100, so that when water is being conveyed, the water can enter the patch box 102 through the inlet 103.

[0065] The outlet 104 is positioned opposite the inlet 103, so that the water flows out from the outlet 104 after passing through the inside of the patch box 102.

[0066] The baffle 108 can block the flow of water. At the same time, it extends into the inside of the patch box 102 through the socket 105. Since the socket 105 is staggered, the baffle 108 is also staggered, so that the staggered baffle 108 inside the patch box 102 forms a maze-like channel. When the water flows into the patch box 102, it will cause the water flow to be turbulent, which can not only reduce the water pressure when the water flows, but also reduce the accumulation of impurities inside the patch box 102.

[0067] The groove 107 is used to place the patch cover 106 and serves to position and restrict the patch cover 106.

[0068] The patch cover 106 is fixedly connected to all the baffles 108. Its own movement drives all the baffles 108 to move, which facilitates subsequent cleaning of the inside of the patch.

[0069] The connecting rod 109 serves to connect the baffle 108 and the pressing plate 110.

[0070] When the pressing plate 110 is operated, the baffle 108 moves synchronously via the connecting rod 109.

[0071] The pressing plate 110 is pressed by the operator and the force is transmitted to the baffle 108 through the connecting rod 109 to control the position of the baffle 108, thereby changing the channel inside the patch box 102.

[0072] The rubber pad 111 is made of rubber and has a certain elasticity. When the pressing plate 110 is pressed, the rubber pad 111 will be compressed. When the pressing plate 110 is released, the compressed rubber pad 111 will return to its original shape, thereby allowing the pressing plate 110 to return to its original position.

[0073] Any of the sockets 105 slides against the outer wall of the baffle 108.

[0074] The sliding contact between the socket 105 and the outer wall of the baffle 108 allows the baffle 108 to slide stably under the constraint of the socket 105. As the baffle 108 gradually exits the inside of the patch box 102, each socket 105 will scrape and clean the outer wall of the baffle 108, thus cleaning the impurities attached to each baffle 108.

[0075] A filter screen 200 is provided on the outside of the patch box 102, and the filter screen 200 is located at the water inlet 103.

[0076] The filter screen 200 is used to perform preliminary filtration of the water entering the patch box 102, intercepting impurities in the water and preventing them from entering the patch box 102 and clogging the flow channel or outlet 104, thus ensuring smooth water flow.

[0077] The filter 200 is set to an arc shape that bulges outward from the inside of the patch box 102.

[0078] The combination of the arc-shaped raised filter screen 200 and the patch box 102 optimizes the filtration process when water flows into the patch box 102. When the water in the belt body 100 enters the patch box 102 through the inlet 103, the arc-shaped filter screen 200 intercepts impurities with a larger contact area, while the raised shape reduces the adhesion of impurities, ensuring that the filtered water is clean and unobstructed. This combination not only enhances the filtration effect and reduces the risk of clogging, but also ensures the stability of water delivery, further improving the reliability and water-saving efficiency of the drip irrigation device, and meeting the needs of cotton planting for continuous and precise irrigation.

[0079] The patch cover 106 has symmetrical beveled edges on both sides.

[0080] When the operator applies force to the pressing plate 110, it will indirectly drive the connecting rod 109 and the patch cover 106 to move. At the same time, part of the patch cover 106 is located inside the groove 107, and the other part will protrude from the groove 107. Since one side of the patch cover 106 is set to beveled, and the tilt direction is the same as the water flow direction, the water flow can be guided to flow over the surface of the patch cover 106. At this time, the water flow will exert a force on the surface of the patch cover 106 to push towards the patch box 102. Combined with the deformation of the rubber pad 111, it indirectly restores the displacement caused by the operator pressing the pressing plate 110 to its original state, thereby ensuring the subsequent cleaning of the patch.

[0081] The patch box 102 has a protective frame 201 at the external end, and the pressing pad 110 and the rubber pad 111 are both located inside the protective frame 201.

[0082] The protective frame 201 provides physical protection for the internal pressing plate 110 and rubber pad 111, preventing debris from the external environment, such as soil particles and plant residues, from directly contacting or colliding with the pressing plate and rubber pad, preventing the components from being damaged by external forces or stuck by impurities, and ensuring their normal working condition.

[0083] When water is introduced into the drip irrigation tape:

[0084] S1. Preliminary filtration using a 200mm filter screen:

[0085] After the water is delivered to the patch through the belt 100, the water will pass through the filter screen 200 and enter the patch box 102 from the inlet 103, and then be discharged from the outlet 104.

[0086] The filter screen 200 is designed with an arc-shaped protrusion, with the protrusion direction opposite to the water flow direction. In this way, when the water flows into the filter screen 200, it can not only filter the water flow, but also prevent impurities in the water flow from adhering to the filter holes of the filter screen 200, thereby causing the filter screen 200 to become clogged and affecting the water flow into the patch.

[0087] The opening direction of the inlet 103 is the same as the water flow direction, which makes it easier for the water to flow into the inlet 103.

[0088] S2. Reduced impurity buildup inside the mounting box 102:

[0089] After the water enters the chip box 102, the chip box 102 has several holes 105 arranged alternately from left to right. This causes the installed baffles 108 to also be arranged alternately from left to right. Through the alternating arrangement of the baffles 108, a maze-like channel is formed inside the chip box 102. This channel, from the inlet 103 to the outlet 104, can continuously change the direction of the water flow inside the chip box 102, causing the water flow to become turbulent. On the one hand, this reduces the water pressure of the delivered water flow, preventing impurities from adhering to the flow channel due to the impact of the high-speed water flow; on the other hand, the turbulent movement of the water flow can reduce the accumulation of impurities inside the chip box 102.

[0090] When each baffle 108 is located in the patch box 102, the baffle 108 slides and abuts against the upper wall and side wall of the patch box 102 in a sealed manner. This can prevent water from flowing through the gap between the baffle 108 and the inner wall of the patch box 102, thus preventing the accumulation of impurities.

[0091] S3. Internal cleaning of the chip tray 102:

[0092] When the operator presses the pressing plate 110, it will also move the connecting rod 109, the baffle 108 and the patch cover 106 in sync. As the baffle 108 leaves the inside of the patch box 102, the maze channel inside the patch box 102 will become a rectangular channel, so that the impurities remaining inside the patch box 102 can be easily discharged from the outlet with the water flow.

[0093] When the pressing plate 110 is pressed, the rubber pad 111 will be compressed and deformed. When the baffle 108 slides inside the socket 105, the edge of the socket 105 will scrape the outside of the baffle 108, thereby cleaning the outside of the baffle 108. The impurities cleaned off will also be discharged from the outlet 104 with the water flow.

[0094] When the pressing plate 110 is released, the deformed and compressed rubber pad 111 will return to its original shape, thereby lifting the pressing plate 110 and simultaneously moving the connecting rod 109, baffle 108 and patch cover 106 until each baffle 108 extends back into the patch box 102, forming a maze passage inside the patch box 102.

[0095] There are two connecting rods 109, which are connected to the two farthest baffles 108 respectively. This ensures that the connecting rods 109 and baffles 108 move more stably when the pressing plate 110 is pressed.

[0096] When the distance between the patch cover 106 and the patch box 102 reaches its maximum, the side of the patch cover 106 facing the patch box 102 is flush with the end face of the groove 107. At this time, when the pressing plate 110 is released, the water flow inside the tape body 100 will impact the inclined surface of the patch cover 106. The patch cover 106 will then be subjected to water pressure. Combined with the rebound force of the rubber pad 111 that returns to its original shape after compression, the baffle 108 can quickly extend into the patch box 102. During this process, the reciprocating motion of the baffle further enhances the cleaning effect on impurities inside the patch box and reduces impurity residue.

[0097] S4. Protection of the protective frame 201:

[0098] The protective frame 201 blocks external debris such as soil particles and plant residues from contacting the pressing plate 110 and rubber pad 111, preventing these components from being damaged or stuck, ensuring that movable parts such as the pressing plate 110 and baffle 108 can work normally, and indirectly reducing blockage problems caused by component failure.

[0099] In this embodiment, by pressing and releasing the pressing plate, and with the deformation and reset of the rubber pad, the connecting rod, baffle and patch cover are indirectly driven to move repeatedly. This not only allows the edge of the insertion hole to scrape the outside of the baffle, but also changes the internal spatial structure of the patch box, thereby enabling impurities inside the patch to be discharged with the water flow, enhancing the cleaning effect and reducing residue.

[0100] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
