Description

Technical Field

[0001] The invention relates to the technical field of agricultural irrigation, in particular to a low-load irrigation device. Background Art

[0002] The reel sprinkler is an advanced irrigation equipment. It uses the sprinkler pressure water to drive the water turbine to rotate, and then drives the winch to rotate through the speed change device to realize the automatic recovery of the PE pipe and the automatic movement and spraying of the sprinkler vehicle. Since the sprinkler can control the amount of water sprayed, it avoids surface runoff and deep leakage losses, and improves the utilization rate of water. In addition, the reel sprinkler has a compact structure, low cost, less material consumption, and less field engineering. It has good mobility, and water supply can be used for both pressure mains and pumping units. Therefore, the reel sprinkler is widely used in farmland irrigation, especially in areas with water shortages. It has become one of the important measures to achieve water conservancy and promote agricultural production.

[0003] However, the existing reel-type sprinkler irrigation machine needs to fix the sprinkler head car on the reel car when storing it, and when finally fixing the sprinkler head car or sprinkling in situ, it is necessary to use a locking device to fix the reel to prevent the reel from rotating. However, the existing locking device simply drives the locking shaft through a hydraulic cylinder, an air cylinder or an electric push rod to extend and retract, so that the locking shaft is movably connected to the positioning device and pushed into the movable groove. Sudden mechanical failures cannot be accurately judged, which is very likely to cause accidents; and the existing reel-type sprinkler irrigation machine has a low sprinkling efficiency, because the sprinkler pressure water is required to drive the water turbine to rotate, and the internal water pressure of the irrigation water will be lost when flowing through a long-distance water delivery hose, such as a water pipe collection for farmland water conservancy irrigation areas proposed in Chinese patent CN212923897U. The winding device comprises a bracket, a winding reel, a winding shaft, a hand wheel and a base; the bottom end of the bracket is fixedly mounted on both sides of the base, the upper end of the bracket is fixed on the outer side of the winding reel, the winding shaft is arranged between the two winding reels, the two ends of the winding reel are mounted in the center of the two winding reels through bearings, and one end of the winding shaft is fixedly connected to the hand wheel on the outer side of the winding reel; a horizontally arranged transmission roller is connected to the side wall between the two winding reels, a water delivery nozzle is wound on the winding shaft, and the water delivery nozzle rolls on the transmission roller when winding. This traditional sprinkler reel requires a very long water delivery hose when in use, so the water pump load requirement is relatively high, resulting in high energy consumption of the reel-type sprinkler when used for a long time. Summary of the invention

[0009] Preferably, a partition is provided in the water storage barrel, and the partition divides the water storage barrel into two independent water tanks. The water pipes are wound into two groups on the water storage barrel, and the two groups of water pipes are respectively connected to the two water tanks, and the two groups of water pipes are wound on the water storage barrel in the same spiral direction. Both groups of water pipes are connected to the nozzle cart, and the nozzle cart is arranged on both sides of the reel cart; when the water storage barrel rotates, the two groups of water pipes are driven to drag the nozzle carts on both sides to move.

[0013] Preferably, wheels are provided at the bottom of the reel trolley and the nozzle trolley.

[0014] (III) Beneficial effects: Compared with the prior art, the present invention provides a low-load irrigation device having the following beneficial effects: 1. The low-load irrigation device can limit the rotation of the water tank through the coordinated use of the lock structure and the transmission chain structure. When the water tank rotates abnormally, the overload protection module can prevent the lifting and translation structure from being stuck when it is advancing or retreating, causing the lifting and translation structure to be pushed and trigger the overload protection. The lock device can then issue an early warning, which greatly ensures the safety and stability of the device. The lock device can be coded and adjusted, and the distance can be adjusted through coding. The control distance greatly improves the accuracy of the telescopic device.

[0015] 2. The low-load irrigation device, through the coordinated use of the water storage barrel structure and the water pipe structure, the sprinkler vehicle can start sprinkling from both sides of the irrigation area at the same time and gradually move towards the middle. This two-way operation method greatly shortens the time required for sprinkling the entire area. In contrast, the traditional sprinkler can usually only start from one edge and gradually move to the other edge. Its sprinkling path is long and the efficiency is low. The design of the device enables the sprinkler vehicles on both sides to work at the same time, which significantly improves the working efficiency and reduces the energy consumption during the operation of the equipment. At the same time, it can reduce the moving distance and friction loss of the sprinkler vehicle and the water pipe. Since the device adopts double-sided irrigation and the two water tanks can work independently, the output power of the water pump can be adjusted according to the actual irrigation needs. During double-sided irrigation, although the two water pumps work at the same time, since the amount of water in each water tank is relatively small, the load of each water pump is also relatively small. This flexible water pump load adjustment method can reduce the energy consumption of the entire device. In addition, the device shortens the length of each set of water pipes by designing double-sided irrigation and independent water tanks, thereby reducing the loss of water pressure in the water pipes, effectively reducing the working pressure and energy consumption of the water pump, and further improving the irrigation efficiency.

[0016] 3. The low-load irrigation device, through the coordinated use of the partition structure and the water storage barrel structure, can choose to fill only one water tank according to different irrigation needs and site conditions, so that the corresponding sprinkler vehicle can perform single-sided irrigation, or one side of the water tank is filled with high-pressure water and the other side is filled with low-pressure water, so that the sprinkler vehicle on one side can be reeled in for sprinkler irrigation, while the other side is sprinkler irrigation in situ because the low-pressure water-filled water bucket is not reeled in. This flexibility enables the device to better adapt to the specific irrigation needs of farmland or park. At the same time, if the sprinkler vehicle or related components on one side fail, it can immediately switch to single-sided irrigation mode to continue irrigation, and arrange maintenance at the same time to ensure that the overall irrigation operation is not affected.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-Figure 5A low-load irrigation device includes a reel 1, a nozzle trolley 12, and a water pipe 5. The reel trolley 1 is rotatably connected to a water barrel 2. The water barrel 2 rotatably connected to the reel trolley 1 and the water pipe 5 are designed to be rolled up on the water barrel 2 and connected to the inside of the water barrel 2, mainly to utilize the rotation of the water barrel 2 to roll up and release the water pipe 5. When the water barrel 2 rotates, the water pipe 5 can be driven to be rolled up or released in an orderly manner, thereby adjusting the position of the nozzle trolley 12. The water pipe 5 is rolled up on the water barrel 2 and connected to the inside of the water barrel 2. The water outlet end of the water pipe 5 is connected to the nozzle trolley 12. The water outlet end of the water pipe 5 is connected to the nozzle trolley 12 in order to directly transport the water source to the nozzle trolley 12 for irrigation operations. The nozzle trolley 12 is equipped with a nozzle that can spray water evenly on crops. Please refer to Figure 8The reel trolley 1 is also fixedly provided with a stopper 7. The stopper 7 is fixedly provided on the reel trolley 1 to fix the position of the water storage barrel 2 when necessary to prevent it from rotating accidentally. During the irrigation process, it is sometimes necessary to pause or adjust the position of the sprinkler trolley 12. At this time, it is necessary to lock the water storage barrel 2 through the stopper 7 to ensure the smooth progress of the irrigation operation. A transmission shaft 10 is arranged above the stopper 7, and a transmission chain 11 is arranged between the transmission shaft 10 and the water storage barrel 2. The transmission shaft 10 is arranged above the stopper 7 and is connected to the water storage barrel 2 through the transmission chain 11 in order to realize the rotation control of the water storage barrel 2. The transmission shaft 10 can transmit power to the water storage barrel 2 to rotate it at the required speed and direction. The transmission chain 11 plays the role of transmitting power and maintaining transmission stability. The stopper 7 is provided with a lock buckle 71, and a lifting and translation structure 72 is provided between the lock buckle 71 and the stopper 7. When the lock buckle 71 is raised, it clamps the transmission shaft 10 and restricts its rotation. The lock buckle 71 and the lifting and translation structure 72 are provided on the stopper 7 to realize the locking and unlocking functions of the transmission shaft 10. When the lock buckle 71 is raised, it can clamp the transmission shaft 10 and restrict its rotation, thereby fixing the position of the water storage bucket 2. The lifting and translation structure 72 is responsible for controlling the lifting and lowering movement of the lock buckle 71, so that it can quickly lock or unlock the transmission shaft 10 when needed. An encoder for controlling the distance of the lock buckle 71 is provided inside the stopper 7. The encoder for controlling the distance of the lock buckle 71 is provided inside the stopper 7 to realize accurate control of the position of the lock buckle 71. The encoder can monitor the position of the lock buckle 71 in real time, and adjust the lifting and translation structure 72 as needed, so that the lock buckle 71 can accurately clamp or release the transmission shaft 10. An overload protection module is also provided inside the lock device 7, and the overload protection module is connected to the lifting and translation structure 72. The overload protection module is to prevent the lifting and translation structure 72 from being damaged under abnormal circumstances. When the lifting and translation structure 72 is subjected to excessive resistance or encounters other abnormal situations, the overload protection module can quickly cut off the power supply or take other protective measures to prevent the lifting and translation structure 72 from being damaged. The overload protection module is triggered when the lifting and translation structure 72 is translated. The transmission shaft 10 is meshed with the lock device 7 through teeth, and the transmission chain 11 is meshed with the water storage barrel 2 through teeth. The tooth meshing can ensure that the transmission shaft 10 and the transmission chain 11 maintain a stable meshing relationship when transmitting power, thereby avoiding sliding or jumping during the transmission process. Wheels are provided at the bottom of the reel car 1 and the nozzle car 12.

[0031] See also Figure 1-Figure 5The inner wall of the water storage barrel 2 is fixedly connected with a turbine plate 21. When the water flows into the water storage barrel 2 through the water injection pipe 3, it will impact the turbine plate 21 and make it rotate. The rotation of the turbine plate 21 drives the rotation of the entire water storage barrel 2, thereby achieving the purpose of using the energy of the water flow to drive the irrigation device. This design is both energy-saving and environmentally friendly, and at the same time improves the working efficiency of the irrigation device. The water storage barrel 2 is coaxially connected with the water injection pipe 3, and the surface of the water injection pipe 3 is provided with a water injection port 31 for injecting water into the water storage barrel 2. Both ends of the water injection pipe 3 penetrate the water storage barrel 2, and both ends of the water injection pipe 3 are sealed and connected to the water storage barrel 2. The design of such a water injection pipe 3 is to ensure that the water flow can enter the water storage barrel 2 smoothly and continuously, and drive the turbine plate 21 to rotate. The coaxial rotation connection between the water injection pipe 3 and the water storage barrel 2 ensures the stability of the water flow, and the design of the water injection port 31 ensures that the water flow can be evenly distributed in the water storage barrel 2. In addition, the sealed connection between the two ends of the water injection pipe 3 and the water storage barrel 2 prevents water leakage and ensures the normal operation of the irrigation device. The water injection pipe 3 is connected to the water supply pipe 6, and the end surface of the water storage barrel 2 is provided with a connecting pipe 4 connected to the water delivery pipe 5. The water injection pipe 3 is connected to the water supply pipe 6 to provide a stable water source for the irrigation device. The water supply pipe 6 introduces the external water source into the water injection pipe 3 and then enters the water storage barrel 2. The connecting pipe 4 connected to the water delivery pipe 5 provided on the end surface of the water storage barrel 2 is to transport the water in the water storage barrel 2 to the nozzle car 12 through the water delivery pipe 5 for irrigation. When the water storage barrel 2 is filled with water, the turbine plate 21 is pushed to drive the water storage barrel 2 to rotate, and the water delivery pipe 5 is reeled when the water storage barrel 2 rotates; the reel car 1 is provided with a support frame at both ends, the support frame is rotatably connected to the water storage barrel 2, and the two ends of the water supply pipe 6 are fixedly connected to the support frame. The support frame is designed to support and fix the water storage barrel 2 and the water supply pipe 6 to ensure that they can work stably. The rotation connection between the support frame and the water storage barrel 2 allows the water storage barrel 2 to rotate freely when it is impacted by the water flow, thereby driving the movement of the water delivery pipe 5 and the nozzle vehicle 12. A water turbine 8 is provided on the water supply pipe 6 to drive the drive shaft 10 to move. The water turbine 8 is designed to use the power of the water flow to drive the rotation of the drive shaft 10. The water turbine 8 can capture the energy in the water flow and convert it into mechanical energy to drive the drive shaft 10 and drive the water storage barrel 2 to rotate. The driving end of the water turbine 8 is connected to a reducer 9, which is connected to the drive shaft 10. The reducer 9 is designed to reduce the speed of the water turbine 8 output to match the speed requirement of the water storage barrel 2. Since the speed of the water turbine 8 may be too high when it is directly driven, directly connecting it to the drive shaft 10 may cause the irrigation device to operate unstably or be damaged. Therefore, by reducing the speed through the reducer 9, the stable operation of the drive shaft 10 and the water storage barrel 2 can be ensured.

[0032] See also Figure 1-Figure 5, a partition 23 is provided in the water storage barrel 2, and the partition 23 divides the water storage barrel 2 into two independent water tanks 22. The partition 23 is provided in the water storage barrel 2, and the water storage barrel 2 is divided into two independent water tanks 22, mainly to achieve flexible irrigation control and improve irrigation efficiency. By dividing into two independent water tanks 22, the water injection pressure of the two water tanks 22 can be controlled separately, so as to achieve precise control of the irrigation area. In addition, the two independent water tanks 22 can also supply water from different sources or types to meet the irrigation needs of different crops. This design improves the flexibility and adaptability of irrigation. The water pipe 5 is wound on the water storage barrel 2 in two groups, and the two groups of water pipes 5 are connected to the two water tanks 22 respectively, and the two groups of water pipes 5 are wound on the water storage barrel 2 in the same spiral direction. The design of winding the water pipe 5 in two groups on the water storage barrel 2 and connecting the two independent water tanks 22 is to ensure that the water in the two water tanks 22 can be transported to the sprinkler vehicle 12 for irrigation through their respective water pipes 5. The two groups of water pipes 5 are connected to the nozzle car 12, and the nozzle car 12 is arranged on both sides of the reel car 1; Fig.10 When the water storage barrel 2 rotates, it drives the two groups of water pipes 5 to drag the nozzle vehicles 12 on both sides to move.

[0033] See also Figure 4 , Figure 5 , Figure 6 , Figure 7 , Fig. 9 and Fig.11The partition 23 is a convex partition 231 and a concave partition 232 made of iron. The convex partition 231 and the concave partition 232 are respectively slidably connected to the independent water tanks 22 on both sides, mainly to achieve flexible switching between independent rotation and synchronous rotation of the two water tanks 22. The iron material can be attracted by the magnetic block 24. The sliding connection design allows the partition 23 to move relative to each other when the pressure in the water tank 22 changes, thereby achieving independent or synchronous rotation of the water tank 22. And a magnetic block 24 is set between the concave partition 232 and the convex partition 231 and the water tank 22. The magnetic block 24 attracts the concave partition 232 and the convex partition 231 to reset. The design of the magnetic block 24 attracts the concave partition 232 and the convex partition 231 to reset is to keep the position of the partition 23 stable when synchronous rotation is not required. When there is no water in the water tank 22 or the water injection pressure is low, the magnetic block 24 will attract the concave partition 232 and the convex partition 231 to reset, so that they are close together, thereby preventing the water tank 22 from rotating unnecessarily. The convex partition 231 is provided with a protrusion 233, and the concave partition 232 is provided with a groove 234 matching the protrusion 233, so that the two water tanks 22 can rotate synchronously when needed. When both water tanks 22 are filled with water and the pressure increases, the convex partition 231 and the concave partition 232 will be squeezed to move toward the sliding cavity 25, and the protrusion 233 will be inserted into the groove 234, so that the two water tanks 22 can rotate synchronously. A limit ring 26 is provided between the concave partition 232 and the convex partition 231, and the limit ring 26 is connected to the water tanks 22 on both sides by a sealed rotation, so that the water tanks 22 on both sides can rotate relatively independently. A sliding cavity 25 is provided between the concave baffle 232 and the convex baffle 231. The sliding cavity 25 is designed to provide space for the baffle 23 to move. When the water injection pressure in the water tank 22 increases, the baffle 23 will be squeezed and moved toward the sliding cavity 25. An annular baffle 261 inserted into the sliding cavity 25 is provided on the limiting ring 26, and the diameter of the annular baffle 261 is smaller than the diameters of the convex baffle 231 and the concave baffle 232, so that the sliding range of the convex baffle 231 and the concave baffle 232 can be limited. When the water injection pressure in the water tank 22 increases, the water tanks 22 on both sides will respectively squeeze the convex baffle 231 and the concave baffle 232 toward the sliding cavity 25, and after the protrusion 233 is removed into the groove 234, the water tanks 22 on both sides rotate synchronously, as shown in FIG. Figure 6As shown. The convex partition 231 and the concave partition 232 are coaxially assembled, and a plurality of grooves 234 and protrusions 233 are provided along the circumferential direction of the water tank 22. The plurality of grooves 234 and protrusions 233 can ensure that the two water tanks 22 can be more stably connected together when rotating synchronously; the outer diameter of the groove 234 is smaller than the inner diameter of the annular baffle 261. When the convex partition 231 and the concave partition 232 are initially adsorbed by the magnetic block 24, the distance from the end face of the concave partition 232 to the annular baffle 261 is equal to the distance from the end face of the convex partition 231 to the annular baffle 261, and the end face of the protrusion 233 is coplanar with the right end face of the annular baffle 261, and the depth of the groove 234 is equal to the distance from the end face of the concave partition 232 to the annular baffle 261. This design is to ensure that in the initial state, the concave partition 232 and the convex partition 231 can fit tightly together and maintain a relatively stable position. At the same time, the end face of the protrusion 233 is coplanar with the right end face of the annular baffle 261 and the depth of the groove 234 is equal to the distance from the end face of the concave partition 232 to the annular baffle 261, which can ensure that when synchronous rotation is required, the protrusion 233 can be accurately inserted into the groove 234, thereby realizing synchronous rotation of the two water tanks 22.

[0034] Working Principle: Please refer to Figure 5 and Figure 8 When the device is in the reeling state, the stopper 7 is started, and the stopper 7 makes the lock buckle 71 press against the transmission shaft 10 through the lifting and translation mechanism. Since the lock buckle 71 is in a gear meshing relationship with the transmission shaft 10 at this time, it can prevent the rotation of the transmission shaft 10, thereby limiting the rotation of the water storage barrel 2. At the same time, the overload protection module is connected to the lifting and translation structure 72. When the water storage barrel 2 rotates abnormally, the overload protection module can prevent the lifting and translation structure 72 from being stuck when it is advancing or retreating, causing the lifting and translation structure 72 to be pushed and trigger the overload protection, and then the stopper 7 is used for early warning, which greatly ensures the safety and stability of the device. In addition, the stopper 7 can be coded and adjusted, and the distance can be adjusted through coding. The control distance greatly improves the accuracy of the telescopic device.

[0035] See also Figure 1 , Figure 2 and Fig.10 When using the irrigation device, water is filled into the water injection pipe 3 through the water supply pipe 6, so that the turbine plate 21 in the water storage barrel 2 is impacted by the water flow, thereby driving the water storage barrel 2 to rotate. At the same time, when the water flows through the water injection pipe 3, the turbine will also drive the transmission shaft 10 and rotate the water storage barrel 2 through the transmission chain 11. The sprinkler vehicles 12 on both sides of the water storage barrel 2 are respectively set at the two ends of the area to be irrigated, and the reel vehicle 1 is set at the midpoint of the two ends of the irrigation area. When the water storage barrel 2 rotates, the sprinkler vehicles 12 on both sides will be dragged toward the reel vehicle 1 through the water supply pipe 5. In this process, the sprinkler vehicles 12 will irrigate the areas on both sides. This design is because the irrigation is gradually moved from both sides of the irrigation area to the middle. Fig.10As shown, compared with the traditional sprinkler irrigation machine using a sprinkler head vehicle 12 to move from one layer of the sprinkler irrigation area to the other side, the sprinkler irrigation time of the device is greatly reduced and the working efficiency of the device is improved.

[0036] See also Figure 6 , Figure 7 , Fig. 9 and Fig.11 At the same time, when the device is in use, it can also realize single-sided sprinkler irrigation with the sprinkler vehicle 12. By rotating the limit ring 26 connected at the center of the water storage barrel 2, the water tanks 22 on both sides can rotate independently. When only one side of the water tank 22 is filled with water, the pressure in the water tank 22 increases, which will squeeze the partition 23 in the middle position of the water storage barrel 2 to slide. When the left water tank 22 is filled with water, the convex partition 231 will be squeezed to break away from the attraction of the magnetic block 24 and move toward the annular baffle 261, so that the right end face of the convex partition 231 is attached to the annular baffle 261. If the right water tank 22 is not filled with water at this time, the convex block 233 on the convex partition 231 cannot be inserted into the groove 234, and the left water tank 22 can only rotate by itself, thereby realizing single-sided sprinkler irrigation with the sprinkler vehicle 12. Fig. 9 As shown, if the right water tank 22 is also filled with water, the water pressure on the right side will increase, which will squeeze the concave baffle 232 to break away from the attraction of the magnetic block 24 and move toward the annular baffle 261, so that the left end surface of the concave baffle 232 is attached to the annular baffle 261. At this time, the convex block 233 on the convex baffle 231 is inserted into the groove 234 of the concave baffle 232, thereby realizing the synchronous rotation of the water tanks 22 on both sides for irrigation, as shown in FIG. Figure 7 As shown, if the left water tank 22 is not filled with water and the right water tank 22 is filled with water, the right water tank 22 rotates and single-sided irrigation is achieved.
