Description

Technical Field

[0001] The present invention belongs to the technical field of hose winding, and specifically refers to a garden irrigation hose winding device. Background Art

[0002] In garden and greening maintenance projects, watering and irrigation is a core link to maintain the healthy growth of plants. As the main water conveyance tool, the hose undertakes the important task of accurately delivering water sources to the areas to be irrigated. After the irrigation operation is completed, the hose needs to be wound regularly for proper storage and efficient reuse.

[0003] Currently, the existing garden irrigation hose winding devices have the following problems: When the existing garden irrigation hose winding device conveys irrigation water to the irrigation area, since the hoses are wound around the outside of the roller, the hoses are squeezed against each other, reducing the internal space of the hoses and making it difficult for the irrigation water to flow through. It is necessary to remove all the hoses wound around the outside of the roller and then connect the water source to irrigate the irrigation area, resulting in a relatively long distance between the unreeled hoses and the water source relative to the irrigation area, increasing the labor intensity of subsequent hose winding. Moreover, after the traditional garden irrigation hose winding device is used for irrigation, a large amount of irrigation water remains inside the hoses, causing the hoses to be prone to hydrolysis or oxidation reactions in a humid environment and shortening the service life of the hoses. Therefore, it cannot meet the current usage requirements of garden irrigation hose winding devices. Summary of the Invention

[0004] In view of the above situation, to overcome the defects of the prior art, the present solution provides a garden irrigation hose winding device that can adaptively unreel the hose according to the positions of the water source and the irrigation area and can air-dry the humid environment inside the hose after use.

[0005] The technical solution adopted by the present solution is as follows: A garden irrigation hose winding device proposed by the present solution includes a winding frame, moving wheels, a handrail frame, a winding mechanism, a segmentation mechanism, and an air-drying mechanism. The segmentation mechanism includes: multiple groups of water-receiving components arranged at intervals along the length direction of the hose. Each group of water-receiving components includes a water-receiving pipe communicating with the side wall of the hose and a water-receiving valve provided at the end of the water-receiving pipe; a water supply component provided at the bottom of the winding frame, including a telescopic pipe and an insertion valve provided at the end of the telescopic pipe. The function of the insertion valve is to selectively dock with any one of the water-receiving valves after unreeling; a squeezing and sealing component provided at the bottom of the winding frame, including a liftable arc-shaped plate, which functions to squeeze the unreeled hose to form a sealed partition. The air-drying mechanism includes an air extraction pump, and its exhaust end is connected to the water supply valve through a pipeline, and functions to inject air flow into the hose after use.

[0006] As a further optimization of the solution in this case, the water connection valve is normally in a closed state and only opens when it is docked with the insertion valve; the squeezing and sealing assembly further includes: a squeezing rod passing through the bottom of the winding frame, the arc-shaped plate is fixed to the top end of the squeezing rod; a squeezing spring sleeved on the squeezing rod, connecting the arc-shaped plate and the winding frame; a squeezing electromagnet arranged at the bottom end of the squeezing rod, whose function is to adsorb the metal bottom wall of the winding frame when electrified to move the arc-shaped plate upward to squeeze the water belt.

[0007] Preferably, the water supply assembly further includes: water supply cylinders symmetrically fixed to the inner wall of the winding frame; a water supply valve connecting the water supply cylinder and an external water source, one end of the telescopic pipe is connected to the water supply cylinder, and the other end is connected to the insertion valve.

[0008] Preferably, the winding mechanism includes: a winding and unwinding assembly: servo motors symmetrically arranged on both sides of the winding frame, a winding and unwinding shaft passing through the winding frame, and a winding and unwinding roller fixed to one end of the winding and unwinding shaft, the winding and unwinding roller is rotatably connected to the winding frame; a guiding assembly: a guiding frame arranged at one end of the winding frame, and a through strip-shaped groove is provided on its side wall; a water conveying assembly: including a water belt wound around the winding and unwinding roller, a spray pipe penetrating the strip-shaped groove and connecting the water belt, and a limiting slide plate and a tension spring arranged on the spray pipe.

[0009] Preferably, the water conveying assembly further includes: multiple groups of annular rubber strips, which are equidistantly fixed to the outer wall of the water belt; a fixing plate fixed to the end of the spray pipe, the limiting slide plate is slidably sleeved on the spray pipe, and both ends of the tension spring are respectively connected to the fixing plate and the limiting slide plate.

[0010] Preferably, the width of the strip-shaped groove of the guiding frame is smaller than the outer diameter of the limiting slide plate, and its function is to intercept the limiting slide plate during winding, forcing the tension spring to compress so that the water belt is tightly wound.

[0011] Preferably, it further includes a controller, which is fixed on the armrest frame and is electrically connected to the servo motor, the squeezing electromagnet and the air extraction pump, and its functions are: controlling the squeezing electromagnet to be electrified during irrigation to form a water belt partition; controlling the air extraction pump to send air into the water belt after irrigation ends; controlling the forward and reverse rotation of the servo motor to realize the unwinding and winding of the water belt.

[0012] Preferably, the air drying mechanism is linked with the segmenting mechanism: when performing regular maintenance, the controller controls the servo motor to unwind the water belt to expand the rubber strip to open the water belt, and at the same time starts the air extraction pump to inject air into the water belt through the nearest water connection valve.

[0013] The beneficial effects obtained by this solution with the above structure are as follows: Compared with the prior art, the present solution adopts a combination of a retracting mechanism and a segmenting mechanism. With the coordinated use of a winding and unwinding assembly, a guiding assembly, a water delivery assembly, a water receiving assembly, a water supply assembly, and a squeezing and sealing assembly, selective unwinding is achieved through the segmenting mechanism: the insertion valve is docked with any water receiving valve to prevent the complete unwinding of the water hose, reducing the difficulty of winding; the squeezing and sealing assembly provides dynamic sealing: the arc-shaped plate squeezes the unwound water hose to prevent irrigation water from entering and reduce the wet area; the air drying mechanism actively dehumidifies: the air pump injects air into the water hose to inhibit hydrolysis or oxidation of the material. According to the distance between the position of the nozzle and the irrigation water source, the water hose for sprinkler irrigation is unwound appropriately, reducing the labor intensity of the winding operation. Through multiple groups of water connection pipes arranged on the side wall of the water hose, it is possible to prevent irrigation water from flowing inside the water hose wound around the outer side of the winding roller, ensuring the water supply for sprinkler irrigation of the water hose. Moreover, under the extrusion of the arc-shaped plate, it is possible to prevent irrigation water from flowing into the inside of the water hose wound around the outer side of the winding roller that is not participating in irrigation, reducing the air drying area inside the water hose after irrigation operation, and improving the winding and unwinding efficiency of the water hose to a certain extent.

The water hose 13 is wound around the outside of the winding and unwinding roller 8. Multiple groups of the rubber strips 14 are arranged on the outside of the water hose 13. The spray water pipe 15 penetrates through the strip-shaped groove 11 and is connected and arranged at one end of the water hose 13. The fixing plate 16 is arranged at the end of the spray water pipe 15 away from the water hose 13.

The tension spring 18 is arranged between the fixing plate 16 and the limiting sliding plate 17 on the outside of the spray water pipe 15. The air extraction pump 34 is arranged on the inner wall of the winding frame 1.

[0021] The water receiving assembly 20 includes a water receiving pipe 21 and a water receiving valve 22. Multiple groups of the water receiving pipes 21 are communicatively arranged on the side wall of the water hose 13. The water receiving valve 22 is communicatively arranged on the side of the water receiving pipe 21 away from the water hose 13, and the normal state of the water receiving valve 22 is closed. The water supply assembly 26 includes a water supply cylinder 27, a water supply valve 28, a telescopic pipe 29, and a plugging valve 30. The water supply cylinder 27 is symmetrically arranged on the inner bottom wall of the winding frame 1.

The telescopic pipe 29 is communicatively arranged on the side of the water supply cylinder 27 away from the water supply valve 28. The plugging valve 30 is communicatively arranged on the side of the telescopic pipe 29 away from the water supply cylinder 27. The squeezing and sealing assembly 33 includes a squeezing rod 32, an arc-shaped plate 31, a squeezing spring 25, and a squeezing electromagnet 24. The squeezing rod 32 penetrates through the bottom of the winding frame 1 below the water hose 13. The arc-shaped plate 31 is arranged on the upper wall of the squeezing rod 32. The squeezing spring 25 is arranged between the arc-shaped plate 31 on the outer side of the squeezing rod 32 and the winding frame 1. The squeezing electromagnet 24 is arranged on the bottom wall of the squeezing rod 32, and the normal state of the squeezing spring 25 is shortened.

[0022] A controller 23 is arranged on the upper wall of the handrail frame 3.

[0023] The controller 23 is electrically connected to the servo motor 6, the squeezing electromagnet 24, and the air extraction pump 34 respectively.

[0024] During specific use, an operator holds the handrail frame 3 and pushes the winding frame 1 to the position of the irrigation water source through the moving wheels 2. The water supply valve 28 is communicatively connected to the water extraction pump or faucet of the irrigation water source through a pipeline. In the initial state, the tensioning and loosening spring 18 is in a shortened state. The limiting sliding plate 17 slides along the water spraying pipe 15 and approaches the fixing plate 16. The water hose 13 is tightly wound around the outer side of the winding roller 8. The gap between the inner walls of the water hose 13 is reduced, and it is impossible for the outside moist air to enter its interior, so the dryness inside the water hose 13 can be maintained. The controller 23 controls the servo motor 6 to start. The servo motor 6 drives the winding shaft 7 to rotate in reverse through the power end. The winding shaft 7 drives the water hose 13 to unwind through the winding roller 8. The tensioning and loosening spring 18 deforms and resets to drive the limiting sliding plate 17 away from the fixing plate 16. The operator pulls the water hose 13 through the water spraying pipe 15. The water hose 13 falls off from the outer side of the winding roller 8. The water hose 13 penetrates through the strip-shaped groove 11 and is laid on the ground. According to the distance between the water source and the position to be irrigated, the unwinding length of the water hose 13 is adjusted to prevent the water hose 13 from completely falling off from the outer side of the winding roller 8, which may cause great difficulties for subsequent winding operations. When the unwinding length of the water hose 13 enables the water spraying pipe 15 to reach the sprinkler irrigation area, the controller 23 controls the servo motor 6 to stop the unwinding operation of the water hose 13. The operator pulls the telescopic pipe 29, and the telescopic pipe 29 drives the mating valve 30 to be butted and communicated with the water receiving pipe 21 unrolled from the outside of the winding roller 8. The water supply valve 28 is opened, and the irrigation water enters the inside of the water supply cylinder 27 through the water supply valve 28, enters the inside of the mating valve 30 through the telescopic pipe 29. The mating valve 30 conveys the irrigation water to the inside of the water hose 13 through the water receiving pipe 21 through the water receiving valve 22. The water hose 13 sprays the irrigation water into the area to be irrigated through the water spray pipe 15. For the other water receiving valves 22 that are not butted with the mating valve 30, since they are closed under normal conditions, the irrigation water inside the water hose 13 will not flow out; To prevent the irrigation water from entering the water hose 13 that does not participate in the irrigation operation, at this time, the controller 23 controls the extrusion electromagnet 24 to start. The extrusion electromagnet 24 is energized to generate magnetism. The extrusion electromagnet 24 adsorbs the metal on the bottom wall of the winding frame 1 through magnetic force. The extrusion electromagnet 24 drives the arc plate 31 through the deformation of the extrusion spring 25 through the extrusion rod 32. The arc plate 31 extrudes the water hose 13 to separate the water hose 13 wound on the outside of the winding roller 8 that does not participate in the irrigation operation from the water hose 13 that participates in the irrigation operation. The inner walls of the extruded water hose 13 are closely attached to each other, so as to block the entry of the sprayed water; After the water hose 13 performs the sprinkler irrigation operation, the water supply valve 28 is disconnected from the water pump or faucet of the irrigation water source. The exhaust end of the air extraction pump 34 is communicated with the water supply valve 28 through a pipeline. The controller 23 controls the air extraction pump 34 to start. The air extraction pump 34 blows gas into the water hose 13 that participates in the irrigation operation to reduce the humidity inside the water hose 13 after the operation. Then, the butted mating valve 30 and the water receiving valve 22 are separated, and the water receiving valve 22 is closed to prevent the water hose 13 from undergoing hydrolysis or oxidation reaction when stored in a long-term humid environment, resulting in a decrease in the elasticity and an increase in brittleness of the water hose 13, and then causing problems such as bursting during use; The controller 23 controls the extrusion electromagnet 24 to be powered off and demagnetized. The extrusion spring 25 elastically resets to drive the arc plate 31 away from the water hose 13. The controller 23 controls the power end of the servo motor 6 to drive the winding shaft 7 to rotate forward. The winding shaft 7 winds the water hose 13 through the winding roller 8. The outer diameter of the limit slide plate 17 is greater than the width of the strip groove 11. Under the limitation of the strip groove 11, the limit slide plate 17 is intercepted on the side of the guide frame 10 away from the water hose 13. As the tension spring 18 deforms, the distance between the limit slide plate 17 and the fixed plate 16 shortens, and the water hose 13 is tightly wound on the outside of the winding roller 8. The inner walls of the water hose 13 are attached to each other to block the entry of external air, and the winding operation of the water hose 13 is completed; During the daily maintenance operation of the water hose 13, it is necessary to regularly dry the inside of the water hose 13. The controller 23 controls the servo motor 6 to start. The servo motor 6 rotates in reverse to drive the winding and unwinding roller 8 to unwind the water hose 13. After the pulling force on the limit slide plate 17 from the water hose 13 decreases, the tension and relaxation spring 18 deforms and resets to drive the limit slide plate 17 away from the fixed plate 16 until the tension and relaxation spring 18 resets to its normal state. The extrusion force between the water hoses 13 disappears. The multiple groups of rubber strips 14 arranged on the outer side of the water hose 13 deform and reset to support the water hose 13, increasing the distance between the inner walls of the water hose 13 to facilitate air circulation. The exhaust end of the air extraction pump 34 is connected to the water receiving valve 22 closest to the winding and unwinding roller 8 through a pipeline. The water receiving valve 22 is opened, and the controller 23 controls the air extraction pump 34 to start. The air extraction pump 34 conveys air flow into the water hose 13 through the exhaust end. Under the air circulation, the moisture inside the water hose 13 evaporates with the flow of the air flow, reducing the humidity inside the water hose 13, and thus keeping the water hose 13 stored in a relatively dry environment; just repeat the above operation when using it next time.
