Description

Technical Field

[0001] The invention relates to the technical field of agricultural irrigation, and in particular to an irrigation system for agricultural planting. Background Art

[0002] Water is an indispensable resource for the growth of many organisms. Crops often need water during the planting process. Irrigation means using water to irrigate the land. The principle of irrigation is that the amount of irrigation, the number of irrigations and the time should be determined according to the water requirements of the plants, the growth stage, the climate and the soil conditions.

[0003] A Chinese patent with authorization announcement number CN111149660B discloses an agricultural planting irrigation device. When watering is needed, the irrigation device recorded in the scheme first installs a belt between a roller and a drive shaft inside a box body. When the roller rolls along the ground, it can drive the drive shaft to rotate, thereby rotating the first pulley on the drive shaft, and finally rotating the set rotating shaft. The rotating shaft drives the half gear to rotate, so that it acts on the driven gear on the outer wall of the first rotating shaft, thereby adjusting the spraying angle of the nozzle and increasing the irrigation range.

[0004] The shortcomings of the above-mentioned prior art solutions are: although the above-mentioned solution can rely on the rolling roller to drive the sprinkler head to swing and adjust the spraying angle, each time it is used for irrigation, a belt needs to be installed and relied on for transmission. In order to ensure that the belt can be effectively transmitted, the belt must be tensioned. Therefore, when installing the belt, it is necessary to use a large force or an instrument to first stretch the belt and then put it on the wheel body. This operation process is not convenient enough, resulting in an insufficient use effect. In addition, the irrigation equipment in the above-mentioned solution relies on a water pipe for water supply, and the water pipe is connected to an external water source. The irrigation equipment recorded in the above-mentioned solution is a mobile irrigation device. In this way, the length of the water pipe will limit the movement of the equipment, and the water pipe may squeeze some crops when passing through some positions as the equipment moves and is dragged. The irrigation equipment recorded in the above-mentioned solution cannot switch to the corresponding mode according to the use environment, resulting in inconvenient operation.

[0020] Beneficial effects of the present invention:

[0021] 1. The irrigation box of the present invention moves in the field that needs irrigation by means of universal wheels and forward wheels, and relies on the main water pump assembly and the main hose to normally transport water to the nozzles distributed on both sides of the irrigation box for irrigation. If the nozzle needs to swing during this process, it is only necessary to loosen the hanging assembly, and the linkage baffle inside the irrigation box will fall into the rotation range of the lever by gravity. During the movement of the irrigation box, since the forward wheel rolls along the ground, the transmission wheel and the transmission belt drive the linkage shaft inside the irrigation box to rotate during the rolling process of the forward wheel, and the linkage shaft drives the lever to rotate. The rotating lever continuously squeezes and pushes the linkage baffle, causing the linkage baffle to drive the nozzle to deflect through the rotating column, thereby realizing the adjustment of the spraying range, and the operation is convenient and effective.

[0022] 2. In the present invention, if the length of the main hose cannot meet the requirements of moving the irrigation box to the corresponding position, or the terrain of the farmland is limited, making it inconvenient for the main hose to move with the irrigation box, the provided lifting tube body can be lifted to separate the bottom of the main hose from the originally connected auxiliary fixed tube body, so that the pipeline between the main hose and the auxiliary hose is disconnected, and the water transported by the main hose directly enters the water storage cavity through the lifting tube body and is stored. At the same time, when the lifting tube body is lifted, the blocking block is linked to block the port of the auxiliary fixed tube body to prevent the water in the water storage cavity from entering the auxiliary fixed tube body and flowing away. Then, the main hose is separated from the irrigation box, and the irrigation box is directly moved. The auxiliary water pump assembly in the water storage cavity is used to transport the separately stored water into the auxiliary hose, and then it is sprayed out through the nozzle to achieve irrigation, thereby preventing the irrigation box from being restricted by the main hose and facilitating switching to the corresponding mode according to the use environment.

[0023] 3. When a certain amount of water is injected into the water storage chamber of the present invention, the liquid level sensing switch generates an induction, causing the electric telescopic rod to extend, driving the baffle bar to rise, so that the external limit of the mounting ring at the end of the main hose is released, and the baffle ring inside the docking tube body at the end of the lifting tube body pushes the mounting ring out by relying on the spring rebound force, thereby realizing automatic separation of the main hose without manual operation.

DETAILED DESCRIPTION

[0036] 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.

[0037] like Figure 1-Figure 10As shown, an agricultural planting irrigation system includes an irrigation box 1 and a main water pump assembly 2, the main water pump assembly 2 is used to be installed in a fixed water area, such as a pond or lake near a farmland; the output end of the main water pump assembly 2 is provided with a main hose 3, the main hose 3 is used to transport water, and the system also includes a control system for controlling various operating parameters of the main water pump assembly 2 for controlling the irrigation progress; a universal wheel 4 is provided on one side of the bottom of the irrigation box 1, and a forward wheel 5 is provided on the other side, the universal wheel 4 and the forward wheel 5 facilitate the movement of the irrigation box 1 in the farmland area, so as to facilitate irrigation, wherein the universal wheel 4 facilitates the steering and movement of the irrigation box 1; both sides of the end of the irrigation box 1 close to the forward wheel 5 are provided with spray nozzles The system further comprises a swing assembly, a water storage chamber 8 and a water delivery pipe. The swing assembly is arranged inside the irrigation box 1, near the position of the forward wheel 5. The swing assembly comprises a linkage shaft 6, a lever 31, a rotating column 42 and a linkage baffle 41. The linkage shaft 6 is horizontally rotatably connected inside the irrigation box 1. The lever 31 is vertically arranged on the linkage shaft 6. A transmission assembly is arranged between the linkage shaft 6 and the forward wheel 5, that is, during the rolling process of the forward wheel 5, the linkage shaft 6 rotates synchronously. Two rotating columns 42 are arranged, which respectively penetrate the two side walls of the irrigation box 1, and the rotating columns 42 are rotatably connected to the side walls of the irrigation box 1. A coil spring is connected between the rotating end of the rotating column 42 and the side wall of the irrigation box 1. One side of each rotating column 42 is connected to the side wall of the irrigation box 1. The corresponding nozzles 40 are connected, and the other sides are fixedly connected with protrusions 43. Two linkage baffles 41 are provided, and they are slidably set on the corresponding protrusions 43 respectively. The specific sliding setting is: a strip slide groove 44 is vertically opened on the protrusion 43, and the linkage baffle 41 is slidably connected with the protrusion 43 through the vertically opened strip slide groove 44. The ends of the two linkage baffles 41 away from the corresponding rotating column 42 are brought together. A hanging component is provided above the two linkage baffles 41, and the linkage baffle 41 is above the linkage shaft 6. When the hanging component hangs the linkage baffle 41, the distance between the bottom of the linkage baffle 41 and the linkage shaft 6 is greater than the length of the lever 31, and the hanging component makes the two linkage baffles 41 After the descent, the linkage shaft 6 drives the lever 31 to rotate, and the lever 31 can continuously squeeze through the position between the two linkage baffles 41. Each time the lever 31 squeezes through the position between the two linkage baffles 41, the linkage baffle 41 deflects, thereby driving the corresponding rotating column 42 to rotate, and the rotating column 42 drives the spray head 40 to deflect, thereby achieving spraying angle adjustment. During the deflection of the rotating column 42, the coil spring is tightened to generate a rebound force. In this way, when the lever 31 passes through the position of the linkage baffle 41, the rotating column 42 rotates and resets by relying on the rebound force of the coil spring. In this way, when the lever 31 repeatedly passes between the two linkage baffles 41, the spray head 40 can achieve reciprocating deflection, which is convenient for large-scale irrigation.

[0038] The water delivery pipe includes a secondary hose 11 and a switchable pipe assembly. Two secondary hoses 11 are provided. One end of the two secondary hoses 11 passes through the corresponding protrusion 43 and the rotating column 42 respectively, and then communicates with the corresponding nozzle 40. The other end is commonly connected to one end of the switchable pipe assembly. The other end of the switchable pipe assembly is docked with the end of the main hose 3. In this way, the water delivered by the main water pump assembly 2 is delivered to the switchable pipe assembly through the main hose 3, and then divided into the two secondary hoses 11 through the switchable pipe assembly, and finally sprayed out through the nozzle 40. In addition, due to the existence of the secondary hoses 11, there is no obstacle for the rotating column 42 to drive the nozzle 40 to rotate.

[0039] The water storage chamber 8 is arranged inside the irrigation box 1 and close to the universal wheel 4, and an auxiliary water pump assembly 7 is arranged at the inner bottom of the water storage chamber 8. The water outlet end of the auxiliary water pump assembly 7 is connected with the switchable pipe assembly. When the main hose 3 is not convenient to move with the irrigation box 1 due to limited length or farmland terrain, the main hose 3 can be used to inject water into the water storage chamber 8 through the switchable pipe assembly, and then the main hose 3 is separated from the switchable pipe assembly, and then the irrigation box 1 is moved independently, and the auxiliary water pump assembly 7 is started, so that the auxiliary water pump assembly 7 transports the water in the water storage chamber 8 to the sprinkler 40 through the switchable pipe assembly.

[0040] It should be noted that the above-mentioned transmission assembly includes a transmission wheel 38 and a transmission belt 39. There are two transmission wheels 38. The linkage shaft 6 and the forward wheel 5 are both coaxially connected to one transmission wheel 38. The transmission belt 39 is cooperatively connected between the two transmission wheels 38. When the forward wheel 5 moves along the ground, the transmission wheel 38 and the transmission belt 39 drive the linkage shaft 6 to rotate.

[0041] It should also be noted that the above-mentioned hanging assembly includes a hanging rope 37, a hanging ring 36, a limiting hole 34 and a hanging part. The hanging rope 37 is connected to the upper side of the linkage baffle 41. The limiting hole 34 is opened at the top of the irrigation box 1, and a soft baffle is arranged in the limiting hole 34. The end of the hanging rope 37 passes through the soft baffle, and the hanging ring 36 is connected to the end of the hanging rope 37. The hanging part is arranged at the top of the irrigation box 1, and the hanging ring 36 cooperates with the hanging part. When the hanging ring 36 is hung on the hanging part, the hanging rope 37 just puts the linkage baffle 41 on the upper side of the linkage baffle 41. The plate 41 is lifted to keep it in the raised position. At this time, the lever 31 cannot act on the linkage baffle 41. When it is necessary to make the sprinkler 40 reciprocate for irrigation, the hanging ring 36 is separated from the hanging part, so that the linkage baffle 41 slides down along the protrusion 43 under the action of gravity, and at this time the hanging ring 36 is limited on the soft baffle to avoid entering the irrigation box 1 and being unable to reset. At the same time, due to the existence of the soft baffle, the soft baffle can be stretched and deformed to avoid affecting the swing of the hanging rope 37 with the linkage baffle 41.

[0042] The above-mentioned soft baffle includes an elastic rubber film 35 and a metal ring. The elastic rubber film 35 is connected in the limiting hole 34. The metal ring is set in the middle position of the elastic rubber film 35, and the hanging rope 37 passes through the metal ring. The diameter of the hanging ring 36 is larger than the inner diameter of the metal ring, and the hanging ring 36 can pass through. The elastic rubber film 35 can be stretched and bent to facilitate the swing of the hanging rope 37 with the linkage baffle 41.

[0043] It should be further explained that the above-mentioned switchable pipe assembly includes a main fixed pipe body 9, a secondary fixed pipe body 12, a lifting pipe body 15 and a linkage blocking assembly. The main fixed pipe body 9 is fixedly arranged at the water outlet end of the secondary water pump assembly 7, and the main fixed pipe body 9 passes through the water storage chamber 8 on the side close to the secondary hose 11. The ends of the two secondary hoses 11 are connected to the main fixed pipe body 9. A first one-way valve 10 is arranged at one end of the main fixed pipe body 9 close to the secondary water pump assembly 7. The first one-way valve 10 allows water to enter the main fixed pipe body 9 only through the water outlet end of the secondary water pump assembly 7 and cannot flow back. An end of the main fixed pipe body 9 close to the secondary hose 11 is connected to the secondary fixed pipe body 12, and an end of the secondary fixed pipe body 12 away from the main fixed pipe body 9 is inserted in the water storage chamber 8 and vertically upward. A second one-way valve 29 is arranged at one end of the secondary fixed pipe body 12 close to the main fixed pipe body 9. The second one-way valve 29 allows water to only pass through The water enters the main fixed tube body 9 through the auxiliary fixed tube body 12, and due to the existence of the first one-way valve 10, the water entering the main fixed tube body 9 can only be transported away through the auxiliary hose 11; a connecting screw groove 23 is provided at the top of the water storage chamber 8, and the lifting tube body 15 passes through the connecting screw groove 23. The lifting tube body 15 can slide up and down relative to the connecting screw groove 23. The lifting tube body 15 is rotatably sleeved with an external threaded sleeve 24 threadedly connected to the connecting screw groove 23 near the top position. The upper end of the lifting tube body 15 is provided with a docking pipe joint 18, and the main hose 3 is connected to the docking pipe joint 18, and a liquid level sensing separation component for separating the main hose 3 from the docking pipe joint 18 is provided on the docking pipe joint 18. The end of the auxiliary fixed tube body 12 away from the main fixed tube body 9 is docked with the lower end of the lifting tube body 15, and a linkage blocking component is cooperatively arranged between the auxiliary fixed tube body 12 and the lower end of the lifting tube body 15.

[0044] The linkage blocking assembly includes a linkage rod 27, a blocking block 25 and a connecting guide rail 26. The connecting guide rail 26 is fixedly arranged on the inner wall of the water storage chamber 8 and is close to the end position of the auxiliary fixed tube body 12. The blocking block 25 is slidably connected to the connecting guide rail 26, and the blocking block 25 cooperates with the end of the auxiliary fixed tube body 12. One end of the linkage rod 27 is movably connected to the outer wall of the lifting tube body 15 through a hinge, and the other end is movably connected to the blocking block 25 through a hinge. A first spring 28 is connected between the blocking block 25 and the connecting guide rail 26. When the lower end of the lifting tube body 15 is docked with the upper end of the auxiliary fixed tube body 12, the blocking block 25 is at the end of the connecting guide rail 26 away from the auxiliary fixed tube body 12; at this time, the first spring 28 is in a stretched state;

[0045] When it is necessary to allow the water transported by the main hose 3 to enter the water storage chamber 8, the external threaded sleeve 24 is rotated to disengage the external threaded sleeve 24 from the connecting screw groove 23. At this time, since the limit of the lifting tube body 15 is released, the resilience of the first spring 28 can be released, thereby driving the blocking block 25 to move horizontally along the connecting guide rail 26 to approach the port of the auxiliary fixed tube body 12 inside the water storage chamber 8. At the same time, during the horizontal sliding process, the blocking block 25 relies on the linkage rod 27 to push the lifting tube body 15 to rise and disengage from the auxiliary fixed tube body 12. Finally, the blocking block 25 moves horizontally to block the port of the auxiliary fixed tube body 12 inside the water storage chamber 8, and the lower end of the lifting tube body 15 is suspended in the water storage chamber 8. At this time, the water transported by the main hose 3 enters the lifting tube body 15, and then can be directly discharged into the water storage chamber 8 for temporary storage. When the storage reaches a certain amount, the liquid level sensing separation component separates the main hose 3 from the docking joint 18 at the upper end of the lifting tube body 15 to avoid further water injection.

[0046] The liquid level sensing separation component includes a liquid level sensing switch 14, an electric telescopic rod 20 and an elastic compression member. The liquid level sensing switch 14 is arranged on the inner top of the water storage chamber 8, and the electric telescopic rod 20 is fixedly arranged on the outer wall of the docking joint 18, and the electric telescopic rod 20 is electrically connected to the liquid level sensing switch 14. The telescopic end of the electric telescopic rod 20 is connected with a baffle 19, and the elastic compression member is arranged inside the docking joint 18. The end of the main hose 3 is provided with a mounting ring 16 that matches the docking joint 18, and the outer wall of the mounting ring 16 is provided with a pressure sensing switch 17 that is electrically connected to the main water pump assembly 2. When the pressure sensing switch 17 is pressurized, the main water pump assembly 2 is started. If there is no pressure, the main water pump assembly 2 is shut down. When the main hose 3 needs to be docked to the docking joint 18 at the end of the lifting tube body 15, the end of the main hose 3 is embedded in the docking joint 18 through the mounting ring 16. At this time, the mounting ring 16 pressurizes the elastic compression member to compress it to generate a rebound force. The pressure sensing switch 17 is also pressurized to generate induction, so that the main water pump assembly 2 starts running, and at this time, the electric telescopic rod 20 is contracted, driving the blocking bar 19 to block the outside of the mounting ring 16, limiting it to prevent it from detaching, so that the main hose 3 and the docking pipe head 18 are fixedly docked; when the lifting tube body 15 injects water into the water storage chamber 8 to reach a certain water level, the liquid level sensing switch 14 generates induction, so that the electric telescopic rod 20 extends, and the electric telescopic rod 20 drives the blocking bar 19 to rise and detach from the mounting ring 16. At this time, since the outside of the mounting ring 16 is unlimited, the elastic compression member inside the docking pipe head 18 that was originally squeezed releases the elastic force, and the mounting ring 16 is pushed out from the inside of the docking pipe head 18, so that the main hose 3 and the docking pipe head 18 are automatically separated. At this time, the pressure sensing switch 17 has no pressure, so that the main water pump assembly 2 stops delivering water, so that the irrigation box 1 is separated from the main hose 3, and it is convenient to rely on the water in the water storage chamber 8 as a temporary water source to move freely for irrigation.

[0047] In some specific embodiments, the elastic compression member includes a retaining ring 21 and a second spring 22. The retaining ring 21 is slidably arranged inside the docking pipe joint 18, and the second spring 22 is connected between the retaining ring 21 and the inner wall of the docking pipe joint 18. When the main hose 3 is installed into the docking pipe joint 18 through the mounting ring 16, the retaining ring 21 is squeezed, so that the second spring 22 is compressed to generate a rebound force. In this way, when there is no limit outside the mounting ring 16, the second spring 22 can push the retaining ring 21 by relying on the rebound force, thereby relying on the retaining ring 21 to push out the mounting ring 16.

[0048] In some specific implementation schemes, in order to control the reciprocating swing interval of the sprinkler 40, a plurality of screw holes 30 are equidistantly provided on the linkage shaft 6 in the circumferential direction, a plurality of levers 31 are provided, and a screw head matching the screw hole 30 is provided at one end of the lever 31. An operation port 13 is provided at one end of the irrigation box 1 close to the linkage shaft 6. When the swing interval of the sprinkler 40 needs to be shortened, a plurality of levers 31 are installed on the linkage shaft 6 through the distributed screw holes 30. When the linkage shaft 6 rotates, the distributed plurality of levers 31 can successively and continuously act on the linkage baffle 41, thereby shortening the swing interval of the sprinkler 40 and increasing the swing frequency.

[0049] In some specific embodiments, in order to prevent the hanging ring 36 from being too easily separated from the hanging member, it can be specifically configured as follows: the hanging member includes a connecting block, a rotating hanging rod 32 and a protruding handle 33, the connecting block is fixedly arranged on the top of the irrigation box 1 and is close to the limit hole 34, the rotating hanging rod 32 is laterally rotated and arranged on the connecting block, the protruding handle 33 is fixedly arranged at the end of the rotating hanging rod 32, and the length of the protruding handle 33 is smaller than the inner diameter of the hanging ring 36, when the hanging ring 36 is hung on the end of the rotating hanging rod 32, the protruding handle 33 is made to face upward, at this time, the protruding handle 33 can block the hanging ring 36 to prevent it from being separated from the rotating hanging rod 32, when it is necessary to separate the hanging ring 36 from the rotating hanging rod 32, the rotating hanging rod 32 is rotated so that the protruding handle 33 faces downward, so that the hanging ring 36 can be removed.

[0050] Finally, it should be noted that a battery pack is provided at the bottom of the irrigation box 1 for supplying power to the auxiliary water pump assembly 7 and the electric telescopic rod 20 .

[0051] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0052] First, various operating parameters of the main water pump assembly 2 are set through the control system, and the main water pump assembly 2 is fixedly installed in a pond or lake near the farmland. Then, when the main hose 3 is installed into the docking pipe head 18 through the mounting ring 16, the mounting ring 16 squeezes the retaining ring 21, so that the second spring 22 is compressed to generate a rebound force, and the pressure sensing switch 17 on the mounting ring 16 is also pressurized to generate induction, so that the main water pump assembly 2 starts to run. At this time, if irrigation is not required immediately, the power supply of the main water pump assembly 2 can be cut off through the control system, and then the electric telescopic rod 20 can be retracted to drive the retaining bar 19 to block the outside of the mounting ring 16, limit it, and prevent it from detaching, so that the main hose 3 is fixedly docked with the docking pipe head 18; at this time, the lifting tube body 15 connected to the docking pipe head 18 is fixed to the top of the irrigation box 1 through the external threaded sleeve 24 and the connecting screw groove 23, and the lower end of the lifting tube body 15 is connected to the end of the auxiliary fixed tube body 12;

[0053] Then, the irrigation box 1 is pushed to move along the field route, and the main water pump assembly 2 is started through the control system. The main water pump assembly 2 then delivers water into the lifting pipe body 15 through the main hose 3, and then the water enters the main fixed pipe body 9 through the auxiliary fixed pipe body 12. Due to the second one-way valve 29, water can only enter the main fixed pipe body 9 through the auxiliary fixed pipe body 12, and due to the existence of the first one-way valve 10, the water entering the main fixed pipe body 9 can only be delivered through the auxiliary hose 11, so that the water is diverted to the auxiliary hoses 11 on both sides of the irrigation box 1, and the auxiliary hose 11 allows the water to be sprayed out through the nozzle 40. Since the main hose 3 has a certain length, it is convenient to move with the irrigation box 1, and at the same time, the hanging ring 36 can be separated from the hanging piece. Since the hanging ring 36 is connected to the linkage baffle 41 through the suspension rope 37, the linkage baffle 41 slides down along the protrusion 43 under the action of gravity. At this time, the linkage baffle 41 slides down along the protrusion 43. The movable baffle plate 41 is within the rotation range of the lever 31. As the forward wheel 5 rolls along the ground during the forward movement of the irrigation box 1, the forward wheel 5 drives the linkage shaft 6 to rotate through the transmission belt 39 and the transmission wheel 38 during the rolling process. The linkage shaft 6 drives the lever 31 to rotate. The lever 31 can continuously squeeze through the position between the two linkage baffle plates 41. Each time the lever 31 squeezes through the position between the two linkage baffle plates 41, the linkage baffle plate 41 deflects, thereby driving the corresponding rotating column 42 to rotate. The rotating column 42 drives the spray head 40 to deflect, thereby achieving spraying angle adjustment. During the deflection of the rotating column 42, the coil spring is tightened to generate a rebound force. In this way, when the lever 31 passes through the position of the linkage baffle plate 41, the rotating column 42 rotates and resets by relying on the rebound force of the coil spring. In this way, when the lever 31 repeatedly passes between the two linkage baffle plates 41, the spray head 40 can achieve reciprocating deflection, which is convenient for large-scale irrigation.

[0054] During this process, the water storage chamber 8 is not filled with water, and the overall weight of the irrigation box 1 is relatively light, which meets the requirements of irrigation under normal circumstances. If the length of the main hose 3 cannot meet the requirements of the irrigation box 1 to move to the corresponding position, or the farmland terrain is limited, and it is not convenient for the main hose 3 to move with the irrigation box 1, the external threaded sleeve 24 set on the lifting tube body 15 can be rotated to make the external threaded sleeve 24 disengage from the connecting screw groove 23. At this time, since the limit of the lifting tube body 15 is released, the rebound force of the first spring 28 can be released, thereby driving the blocking block 25 to move horizontally along the connecting guide rail 26 to approach the port of the auxiliary fixed tube body 12 inside the water storage chamber 8. At the same time, during the horizontal sliding process of the blocking block 25, the lifting tube body 15 is lifted and separated from the auxiliary fixed tube body 12 by relying on the linkage rod 27. Finally, the blocking block 25 moves horizontally to block the port of the auxiliary fixed tube body 12 inside the water storage chamber 8, and the lower end of the lifting tube body 15 is suspended in the water storage chamber 8. At this time, the water transported by the main hose 3 enters the lifting tube body 15, and then can be directly discharged into the water storage chamber 8 for temporary storage.

[0055] When the storage reaches a certain amount, the liquid level sensing switch 14 in the water storage chamber 8 generates an induction, causing the electric telescopic rod 20 to extend, and the electric telescopic rod 20 drives the retaining bar 19 to rise and separate from the mounting ring 16. At this time, since the mounting ring 16 has no limit outside, the second spring 22 inside the docking pipe head 18 releases the rebound force, and the retaining ring 21 is used to push the mounting ring 16 at the end of the main hose 3 out of the docking pipe head 18, thereby realizing the automatic separation of the main hose 3 and the docking pipe head 18. At this time, the pressure sensing switch 17 also has no pressure effect, so that the main water pump assembly 2 stops delivering water, thereby facilitating the irrigation box 1 to separate from the main hose 3, and facilitating free movement of irrigation by relying on the water in the water storage chamber 8 as a temporary water source, and starting the auxiliary water pump assembly 7 in the water storage chamber 8. The auxiliary water pump assembly 7 allows the water in the water storage chamber 8 to be transported to the auxiliary hose 11 through the main fixed pipe body 9, and then transported to the nozzle 40 for spraying, which can be switched to the corresponding mode according to the use environment.

[0056] Several embodiments of the present invention are described in detail above, but the embodiments of the present invention are not limited thereto and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
