Description

Technical Field

[0001] This utility model relates to water supply pipes and their application in the field of winch-type sprinkler irrigation technology, particularly a water supply pipe for a self-locking sprinkler irrigation machine. Background Technology

[0002] Winch-type sprinkler irrigation machines wind PE pipes onto a winch. The typical length of the wound PE pipe is around 200-450 meters, with some exceeding 500 meters. They are mainly used for sprinkler irrigation of field crops, grasslands, flowers, fruit trees, and vegetables, as well as for dust suppression. They can also be used for general mobile pipeline laying, making their applications very wide-ranging.

[0003] With the widespread application of winch-type sprinkler irrigation machines, their application scenarios are constantly expanding. The winch-type sprinkler irrigation machine includes: support wheels 1-1, frame 1-2, water supply pipe 1-3, winch 1-4, water delivery pipe 1-5, return conveyor 1-6, guiding device 1-7, sprinkler head carriage 1-8, traction vehicle 1-9, sprinkler head, and frame sprinkler head base. The water delivery pipe 1-5 is a PE pipe.

[0004] Support wheels 1-1 are connected to the bottom of frame 1-2; winch 1-4 and PE return device 1-6 are connected to the upper end of frame 1-2, PE return device 1-6 is connected to the outside of frame of winch 1-4, and guide device 1-7 is connected to the edge of PE return device 1-6; guide device 1-7 is installed on frame 1-2 to guide the PE pipe to be returned and retrieved in an orderly manner. Water supply pipe 1-5 is wound on winch 1-4. The inlet of water supply pipe 1-5 is located on the central axis of winch 1-4 and connected to water supply pipe 1-3. Water supply pipe 1-3 is located on the outside of winch; outlet of water supply pipe 1-5 is led out through guide device 1-7 and connected to nozzle carriage 8; guide device 7 is connected to the edge of return conveyor 6.

[0005] The guiding device 1-7 is mounted on the winch 1-4; the nozzle carriage 1-8 consists of two wheels on both sides of the nozzle frame and the frame 1-2, with the PE pipe fixed to the nozzle seat on the frame, and the nozzle seat connected to the nozzle. The nozzle carriage 1-8 is pulled by the traction power of the tractor 1-9 for spraying operations, simultaneously spraying and retrieving the PE pipe back onto the winch 1-4. During the retrieval process, the guiding device 1-7 ensures that the PE pipe is neatly arranged in the water delivery pipe 1-5 during the winding process, preventing the water delivery pipe 1-5 from becoming tangled.

[0006] The nozzle carriage 1-8 is connected to the tractor 1-9. The tractor 1-9 pulls the nozzle carriage 1-8 forward or backward, and the release or recycling of the PE pipe is completed by this utility model.

[0007] Before the sprinkler irrigation machine starts working, the PE pipe needs to be released and laid out from the winch along the spraying line of the field to be irrigated. Therefore, a mobile power unit is needed to pull the PE pipe out of the winch of the sprinkler irrigation machine and lay it on the ground. Since the PE pipe is wound on the winch, and in addition, it is necessary to pull 200-450 meters of PE pipe along the ground to the other end of the irrigation field, a very powerful traction vehicle is required to complete the task. In some places, large tractors are used as traction vehicles. However, large tractors are bulky and difficult to move in the field, requiring a wide track, resulting in low utilization of the field. Pulling out the PE pipe is a very troublesome task.

[0008] Winch-type sprinkler irrigation machines have the problem of using very heavy and expensive PE pipes, requiring high-power traction equipment to complete the laying task. Utility Model Content

[0009] The purpose of this invention is to provide a water supply pipe for a self-locking sprinkler irrigation machine, which solves the problem that traditional winch-type sprinkler irrigation machines use heavy and expensive PE pipes, requiring high-power traction equipment to complete the laying task.

[0010] The purpose of this utility model is achieved as follows: the water supply pipe for the self-locking sprinkler irrigation machine includes: a self-locking interlocking water supply pipe, a guide steel pipe, an "O" ring seal, a guide pipe, an unfolded water supply pipe cloth, a reel-type sprinkler irrigation machine unit, a gate valve, a high-pressure water inlet pipe, a self-locking zipper device, a self-locking interlocking sealing device, and a steel wire rope.

[0011] The guide steel pipe is located inside the guide pipe, and the unfolded water supply cloth of the reel-type sprinkler unit is coiled on the guide steel pipe. The unfolded water supply cloth is input from one end of the guide pipe and passes through the guide pipe. The unfolded water supply cloth passes through the guide pipe through a self-locking zipper device and a self-locking interlocking sealing device and is led out from the other end, forming a self-locking interlocking water supply pipe. A high-pressure water inlet pipe is vertically installed on the side wall of one end of the guide steel pipe and communicates with it. An "O" ring seal is connected between the outer wall of the other end of the guide steel pipe and the inner wall of the guide pipe. The other end of the high-pressure water inlet pipe is bent through the reel-type sprinkler unit and connected to the gate valve. The steel wire rope is wound on the reel-type sprinkler unit and is output synchronously with the unfolded water supply cloth.

[0012] The aforementioned guide steel pipe has a closed end at one end and an open end at the other end, with an "O"-shaped sealing ring groove on the outer wall of the other end.

[0013] The guide tube has flared ends, with an "O"-shaped sealing groove on the inner side of one end and a self-locking zipper head installed in the middle.

[0014] The reel-type sprinkler unit includes: a winch, a water turbine, a recovery winch reel, and a winch high-pressure water supply pipe; the recovery winch reel is mounted on the water turbine and rotates around the water turbine as its axis; the recovery winch reel has a winch, and the winch high-pressure water supply pipe and high-pressure water inlet pipe are both connected to the water turbine.

[0015] The self-locking zipper device includes a right self-locking zipper and a left self-locking zipper. When the right and left self-locking zippers pass through the self-locking zipper head and the water supply pipe is pulled to unfold, the right and left self-locking zippers passing through the self-locking zipper head automatically close, unfolding the water supply pipe to form a water pipe.

[0016] The self-locking sealing device includes: a self-locking sealing buckle and a self-locking sealing buckle groove; the self-locking sealing buckle and the self-locking sealing buckle groove overlap to form a self-sealing mechanism.

[0017] Beneficial effects: Due to the adoption of the above technical solution, when the self-locking water supply pipe does not bear high-pressure water and is pulled to the required working destination, it can be achieved as follows: First, the unfolded water supply pipe is pulled out from the recovery winch on the reel-type sprinkler unit, enters the guide pipe, and after passing through the internal diversion steel pipe, the unfolded water supply pipe is gradually rolled into an arc shape. Since the two sides of the unfolded water supply pipe are not yet self-locked and sewn together, it is easy to pass through the high-pressure water inlet pipe on the diversion steel pipe. After passing through the high-pressure water inlet pipe, the zipper locking sealing strips and sealing lock buckles embedded on both sides of the unfolded water supply pipe are respectively self-locked and sealed by the self-locking zipper device and the self-locking sealing device fixed on the diversion steel pipe. The unfolded water supply pipe forms a closed self-locking water supply pipe, that is, a self-locking water supply hose. When the machine reaches the desired work destination, the sprinkler truck and its self-locking water hose can be pulled along the field work path by manpower or light traction power using the wire rope synchronously wound on the recovery winch of the reel-type sprinkler unit.

[0018] After the self-locking water supply pipe is pulled to the spraying point, the inlet gate valve is opened, and high-pressure water enters the water turbine through the high-pressure water supply pipe of the sprinkler unit's winch. Driven by the water turbine, the retraction winch is activated, which can then retrieve the traction steel wire rope and unfold the water supply pipe.

[0019] When high-pressure water from the high-pressure inlet pipe enters the guide steel pipe, the high-pressure water can only flow forward along the guide steel pipe into the self-locking water delivery pipe because the rear end of the guide steel pipe is sealed. After the high-pressure water enters the self-locking water delivery pipe, the water delivery pipe is equipped with embedded zipper locking strips and sealing buckles. At the same time, the inner wall of the guide pipe is embedded with multiple "O" sealing rings in the water outlet section. When high-pressure water passes through the self-locking water delivery pipe, the sealed self-locking water delivery pipe expands completely, causing the outer wall of the water delivery pipe to tightly adhere to the inner diameter of the "O" sealing rings embedded in the guide pipe. This ensures that there is no leakage between the water delivery pipe and the zipper gap, or between the water delivery pipe and the guide steel pipe. This ensures that the delivered high-pressure water reaches the nozzle for spraying operations, or reaches the place where high-pressure water is needed.

[0020] During spraying operations, the spray volume can be adjusted according to the amount of water sprayed, and the retraction speed of the spray head truck is achieved through the following scheme:

[0021] The sprinkler truck is secured with a steel wire rope, and its water supply pipe is connected to the self-locking water delivery pipe. When the steel wire rope is wound around the recovery winch on the winch of the reel-type sprinkler unit, the end of the self-locking water delivery pipe slowly enters the guide pipe. After the self-locking water delivery pipe passes the "O" seal ring inside the guide pipe, the two self-locking zipper strips (right and left self-locking zipper strips), the sealing lock buckle and the sealing lock groove, and the self-locking zipper device and the self-locking sealing device unlock the high-pressure pipe of the self-locking delivery pipe, decompose it into an unfolded water delivery pipe and gradually enter the end of the guide pipe. After unlocking, the high-pressure water pipe becomes a pressureless water pipe, forming an unfolded water delivery pipe that slowly, evenly and orderly winds around the recovery winch on the reel-type sprinkler unit in sync with the traction steel wire rope.

[0022] The power used for pipeline retrieval can utilize the power of the water turbine configured in the existing winch-type sprinkler unit. To reduce hydraulic losses and improve hydraulic efficiency by driving the water turbine with high-pressure water, electric motors, diesel engines, gasoline engines, or other power machinery can also be used to drive the winch on the winch of the winch-type sprinkler to achieve pipeline and sprinkler head retrieval.

[0023] Compared with existing winch-type sprinkler irrigation technology, its water delivery pipe has been replaced with a self-locking water delivery pipe, also known as a self-locking water delivery hose, instead of the original PE pipe. The tractor is lightweight, flexible, requires less traction power, and is easy to operate. It solves the problems of the previous traction devices being bulky, having high drive power, wasting energy, and being difficult to move in the field.

[0024] This invention solves the problem that traditional winch-type sprinkler irrigation machines use heavy and expensive PE pipes, requiring high-power traction equipment to complete the laying task, thus achieving the purpose of this utility model.

[0025] advantage:

[0026] 1. By breaking down the water supply pipe into an unfolded water supply pipe network, the problems of water supply pipe traction, retrieval, and storage are solved.

[0027] 2. The zipper self-locking device and self-locking interlocking sealing device make it easy and quick to interlock the two sides of the unfolded water supply pipe into a sealed water supply pipe, replacing the PE pipe on the winch-type sprinkler irrigation machine, reducing the burden of the winch-type sprinkler irrigation machine being entangled in PE and its heavy winch and high-power traction.

[0028] 3. It reduces the resistance and friction of laying or retrieving high-pressure water pipes for sprinkler irrigation machines, improves traction conditions, increases work efficiency, and reduces labor intensity.

[0029] 4. The pipeline can be retrieved and pulled by winding the unfolded water supply pipe and its traction steel wire rope onto the winch of the winch-type sprinkler irrigation machine, which is convenient and quick, and does not require additional winch machinery.

[0030] 5. The power used for pipeline recovery can utilize the power of the water turbine configured in the existing winch-type sprinkler unit. To reduce hydraulic losses and improve hydraulic efficiency by driving the water turbine with high-pressure water, an electric motor, diesel engine, or gasoline engine can also be used to drive the winch on the winch of the winch-type sprinkler to achieve pipeline and sprinkler head retrieval.

[0031] 6. It reduces the width of the passageways used for high-pressure water pipes, thus improving land utilization; it also increases crop yields and improves growers' economic benefits. Attached Figure Description

[0039] The specific embodiments described herein are merely illustrative of the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or adopt similar methods to replace them, but without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0040] Example 1: The water supply pipe for the self-locking sprinkler irrigation machine includes: a self-locking interlocking water supply pipe 1, a guide steel pipe 2, an "O" ring seal 3, a guide pipe 4, an unfolded water supply pipe cloth 5, a reel-type sprinkler irrigation machine unit 6, a gate valve 7, a high-pressure water inlet pipe 8, a self-locking zipper device 9, a self-locking interlocking sealing device 10, and a steel wire rope 13.

[0041] The guide steel pipe 2 is located inside the guide pipe 4. The unfolded water supply cloth 5, which is coiled on the reel-type sprinkler irrigation unit 6, is looped onto the guide steel pipe 2. The unfolded water supply cloth 5 is input from one end of the guide pipe 4 and passes through the guide pipe 4. The unfolded water supply cloth 5 passes through the self-locking zipper device 9 and the self-locking interlocking sealing device 10 inside the guide pipe 4 and is led out from the other end. The unfolded water supply cloth 5 is combined to form the self-locking interlocking water supply pipe 1. A high-pressure water inlet pipe 8 is vertically installed on the side wall of one end of the guide steel pipe 2 and communicates with it. An "O"-shaped sealing ring 3 is connected between the outer wall of the other end of the guide steel pipe 2 and the inner wall of the guide pipe 4. The other end of the high-pressure water inlet pipe 8 is bent and passes through the reel-type sprinkler irrigation unit 6 and is connected to the gate valve 7. The steel wire rope 13 is wound on the reel-type sprinkler irrigation unit 6 and is output synchronously with the unfolded water supply cloth 5.

[0042] The guide steel pipe 2 has a closed end at one end and an open end at the other end, which is connected to the high-pressure water inlet pipe 8. There is a groove for an "O"-shaped sealing ring 3 on the outer wall of the other end.

[0043] The guide tube 4 has flared ends, with an "O" shaped sealing groove on the inner side of one end and a self-locking zipper head installed in the middle.

[0044] The reel-type sprinkler unit 6 includes: a winch 6-1, a water turbine 6-2, a recovery winch 6-3, and a winch high-pressure water supply pipe 6-4; the recovery winch 6-3 is mounted on the water turbine 6-2 and rotates around the water turbine 6-2; the winch 6-1 is located on the recovery winch 6-3, and the winch high-pressure water supply pipe 6-4 and the high-pressure water inlet pipe 8 are both connected to the water turbine 6-2.

[0045] The self-locking zipper device 9 includes a right self-locking zipper 9-1 and a left self-locking zipper 9-2. The right self-locking zipper 9-1 and the left self-locking zipper 9-2 pass through the self-locking zipper head. When the water supply pipe 5 is pulled to unfold, the right self-locking zipper 9-1 and the left self-locking zipper 9-2 passing through the self-locking zipper head automatically close, unfolding the water supply pipe 5 to form a water pipe.

[0046] The self-locking interlocking sealing device 10 includes: a self-locking interlocking sealing buckle 10-1 and a self-locking interlocking sealing buckle groove 10-2; the self-locking interlocking sealing buckle 10-1 and the self-locking interlocking sealing buckle groove 10-2 overlap to form a self-sealing mechanism.

[0047] Before using the water delivery pipe of the self-locking sprinkler irrigation machine, the unfolded water delivery pipe cloth wound on the winch can be released from the winch reel and enter the guide pipe. After passing through the internal guide steel pipe, the unfolded cloth is gradually rolled into an arc shape. Zipper locking sealing strips and sealing locking buckles are embedded on both sides of the unfolded cloth. By the self-locking zipper device and the self-locking sealing device fixed on the guide steel pipe, the zipper locking strips and sealing buckles embedded on both sides of the original high-pressure delivery pipe cloth strip can be self-locked, and the delivery pipe unfolded into a closed self-locking water delivery pipe.

[0048] The unfolded conveying pipe cloth wound on the winch is released from the winch reel and enters the guide pipe. The front and rear ends of the guide pipe are designed in a trumpet shape to facilitate the unfolding of the water conveying pipe cloth to freely enter and exit the guide pipe and prevent the diversion steel pipe from being scratched or damaged by the outside.

[0049] The zipper locking strips embedded on both sides of the water supply pipe strip are tightly connected to the two sides of the unfolded fabric by a self-locking zipper device, locking the opening part into a whole. In this application, the zipper locking strips embedded on the unfolded water supply pipe fabric are moved, while the locking buckle in the self-locking zipper device is fixed to the wall of the guide steel pipe. After locking, the self-locking water supply pipe can be pulled to the destination that needs irrigation by manpower or a light traction vehicle through a traction device.

[0050] After the water supply pipe is unfolded and the high-pressure water inlet pipe passes through the diversion steel pipe on both sides, the zipper locking strip, sealing buckle and sealing groove embedded on the unfolded water supply pipe are engaged together by the self-locking zipper device and the self-locking biting sealing device and move forward synchronously.

[0051] The self-locking water pipe, also known as the self-locking water pipe sealing hose, can be easily and conveniently pulled to the desired destination using manual traction or a lightweight traction device.

[0052] After the self-locking water supply pipe is pulled to the desired destination, it can be connected to the nozzle truck. After the pipeline is connected, the gate valve is opened, and high-pressure water can be delivered into the guide steel pipe through the high-pressure water inlet pipe.

[0053] The high-pressure water inlet pipe is sealed at one end and open at the other. When high-pressure water for irrigation is sprayed, it enters the self-locking water delivery pipe through the guide steel pipe.

[0054] After high-pressure water enters the self-locking water supply pipe, the pipe is equipped with an embedded zipper locking strip and a sealing buckle. At the same time, multiple "O" sealing rings are embedded inside the water outlet section of the guide pipe. When high-pressure water passes through, the self-locking water supply pipe expands completely, causing the outer wall of the water supply pipe to tightly adhere to the inner diameter of the "O" sealing rings embedded inside the guide pipe, ensuring that the water inside the self-locking water supply pipe does not leak out.

[0055] The high-pressure water in the self-locking water supply pipe is connected to the water inlet pipe of the sprinkler truck. To facilitate the backward traction of the sprinkler truck during irrigation, a traction steel wire rope is attached to the sprinkler truck. The steel wire rope, like the self-locking water supply pipe, is synchronously wound at the end on different recovery reels on the winch, ensuring that the self-locking water supply pipe and the steel wire rope move synchronously during irrigation.

[0056] After the self-locking water supply pipe is retracted to the self-locking zipper device and the self-locking sealing device, the high-pressure water supply pipe is opened to separate the rolled pipe, which is then unfolded and the traction steel wire rope is wound onto the winch of the winch-type sprinkler unit, in preparation for moving to another sprinkler point and repeating the above work.

[0057] Its working principle: The unfolded water supply pipe is inlaid with self-locking zippers, self-locking interlocking sealing buckles, and self-locking interlocking sealing grooves on both sides. Before use, the unfolded water supply pipe is neatly wound onto the winch reel for later use. During use, the unfolded water supply pipe is pulled out and inserted into the guide pipe. After passing through the internal drainage steel pipe, the unfolded cloth is gradually rolled into an arc shape. Because the two sides of the unfolded water supply pipe are not yet self-locking and sewn together, it can easily pass through the high-pressure water inlet pipe on the drainage steel pipe. After passing through the high-pressure water inlet pipe, the two sides of the unfolded cloth... The edges are inlaid with zipper-locking sealing strips and sealing buckles. The self-locking zipper device fixed on the guide steel pipe works on the same principle as the zipper of people's clothing, which can lock the two sides of the unfolded water supply pipe into one piece. The self-locking sealing device can lock the corresponding self-locking sealing buckles and self-locking sealing grooves inlaid on both sides of the supply pipe strip to achieve a sealing effect. The unfolded water supply pipe is combined into a self-locking water supply pipe, thus forming a closed soft self-locking water supply pipe.

[0058] The self-locking zipper device and self-locking sealing device fixed on the guide steel pipe form a self-locking mechanism by the zipper locking strips and sealing buckles embedded on both sides of the original high-pressure conveying pipe. The conveying pipe is unrolled and rolled into a circular, sealed self-locking water pipe. When high-pressure water enters the self-locking sealed water pipe, the embedded zipper locking strips and sealing buckles, along with multiple "O" sealing rings embedded in the water outlet section of the guide pipe, cause the sealed self-locking water pipe to expand completely when high-pressure water passes through. This ensures that the outer wall of the self-locking water pipe is tightly bonded to the inner diameter of the "O" sealing rings embedded in the guide pipe, preventing leakage between the self-locking water pipe and the zipper gap, as well as between the self-locking water pipe and the guide steel pipe.

[0059] To ensure the service life of the self-locking water supply pipe and reduce stress damage during traction and retrieval, the end of the self-locking water supply pipe is connected to the water supply pipe of the nozzle trolley. At the same time, a traction steel wire rope is attached to the nozzle trolley. Both the self-locking water supply pipe and the traction steel wire rope are synchronously wound around the winch recovery wheel at their ends to ensure that the pipeline moves synchronously with the steel wire rope during traction and retrieval operations.

[0060] When not transporting high-pressure water, the steel wire rope is pulled manually or by a lightweight traction machine and connected to a self-locking water delivery pipe. The rope is released from the winch reel along the spraying line of the field to be irrigated. During the pulling process, the main steel wire rope bears the traction force, while the self-locking water delivery pipe is basically unaffected and passively pulled out and laid on the ground until the sprinkler truck is pulled to the other end of the field to be sprayed. The length of the self-locking water delivery pipe is generally 150-300 meters.

[0061] During spraying, the self-locking water delivery pipe carries high-pressure water. The end-mounted reel-type sprinkler unit 6 is used; the winch 6-3 is retrieved; the traction wire rope 13, along with the sprinkler head 14 and the self-locking water delivery pipe 1, synchronously enters the guide pipe 2 and guide pipe 4 along the spraying route. After the self-locking water delivery pipe 1 passes the "O" seal 3 inside the guide pipe, the two embedded self-locking zipper strips—right self-locking zipper strip 9-1, left self-locking zipper strip 9-2, and sealing locking buckle 10-1 and sealing locking groove 10-2—unlock the high-pressure pipe of the self-locking delivery pipe 1 through the self-locking zipper device 9 and the self-locking sealing device 10, disassembling it into an unfolded delivery pipe cloth 5, which gradually enters the end of the guide pipe. Since the high-pressure water pipe becomes a pressureless water pipe after unlocking, the unfolded delivery pipe cloth 5 slowly, evenly, and orderly winds around the reel-type sprinkler unit 6 in sync with the traction wire rope. The recovery winch reel 6-3 is located on the top.

[0062] Example 2: The self-locking interlocking sealing device 10 is located inside the self-locking zipper device 9.

[0063] Everything else is the same as in Example 1.

[0064] Example 3: The self-locking interlocking sealing device 10 is located on the inner and outer sides of the self-locking zipper device 9.

[0065] Everything else is the same as in Example 1.

[0066] Example 4: Figure 4 The example shown is an embodiment of a self-locking sprinkler irrigation machine formed by combining the water supply pipe of the self-locking sprinkler irrigation machine with the sprinkler head 14.
