Description

Technical Field

[0001] This utility model relates to the field of irrigation spray guns, specifically a garden irrigation spray gun with a spray bar. Background Technology

[0002] In the field of garden maintenance, irrigation is a key link in ensuring the healthy growth of plants. With the acceleration of urbanization and the increasing attention people pay to the ecological environment, the area of ​​gardens and green spaces is constantly expanding, from urban parks and community green spaces to large botanical gardens. The demand for efficient and precise irrigation equipment is growing. Traditional garden irrigation methods are diverse. In the early days, manual watering with buckets was common. This method was not only inefficient but also labor-intensive and could not meet the irrigation needs of large-area gardens. Later, direct irrigation with water pipes appeared. Although it improved the irrigation range to some extent, it lacked flexibility, the water flow control was not precise enough, it was easy to waste water resources, and it could also damage plants due to excessive water flow impact. With the development of technology, sprinkler irrigation equipment has been gradually applied to garden irrigation. Among them, the spray gun with a spray bar has received widespread attention as a flexible and efficient irrigation tool. It combines the advantages of sprinkler irrigation and manual operation. Workers can hold the spray bar gun and flexibly adjust the irrigation position and angle according to the actual distribution and growth status of garden plants to achieve precise irrigation of plants in different areas.

[0003] Existing technologies still have many shortcomings. Currently, most spray guns with booms lack effective dynamic support structures. When workers extend the boom to irrigate plants over a larger area or at a distance, the increased length, weight at the end, and jet reaction force significantly increase the difficulty of holding the gun. Workers must continuously exert force to overcome these forces, which can easily lead to arm fatigue over long periods, affecting irrigation efficiency and quality. It can even cause operational errors due to hand pain, damaging plants. Some spray guns with simple supports have relatively fixed support methods and cannot adaptively adjust according to the extension and retraction of the boom. When the boom is shortened for close-range irrigation, the extra support components not only take up space but may also hinder the worker's operation, reducing the flexibility of use. Utility Model Content

[0004] The purpose of this utility model is to provide a spray gun with a spray bar for garden irrigation to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A garden irrigation spray gun with a spray boom, comprising,

[0007] A liquid storage tank, wherein a liquid injection port is provided on one side surface of the liquid storage tank, a carrying strap is also provided on one side surface of the liquid storage tank, and a spray gun is provided on one side of the liquid storage tank.

[0008] The upper surface of the liquid storage tank is provided with a support mechanism, which includes a strut assembly and a weighting assembly. The strut assembly includes a connecting frame, which is fixedly installed on the upper surface of the liquid storage tank. A sunshade top plate is provided on the upper surface of the connecting frame. A pivot is provided at the connection between the sunshade top plate and the connecting frame. A limiting protrusion is provided on the upper surface of the sunshade top plate. A storage sleeve is provided on the upper surface of the limiting protrusion. A support rod is provided on one side surface of the storage sleeve.

[0009] The weighting component includes: a weighting liquid tank, which is disposed on one side surface of the liquid storage back box, the upper surface of the weighting liquid tank is connected to the bottom surface of the weighting frame, and two side sliding strips are provided on one side surface of the weighting liquid tank.

[0010] Furthermore, one end of the support rod is connected to one end surface of the spray gun, and a limiting frame that cooperates with the receiving sleeve is provided on one side surface of the limiting protrusion. A weighted frame is provided on the bottom surface of the limiting frame, and a pivot is provided at the connection between the weighted frame and the limiting frame.

[0011] Furthermore, the side surface of the liquid storage tank is provided with a sliding groove that cooperates with the side sliding strip. A connecting spring is provided on the upper surface of the side sliding strip. The upper surface of the connecting spring is connected to the inner upper surface of the sliding groove. An opening is provided on one bottom side of the weighted liquid tank. A telescopic motor is provided inside the weighted liquid tank. A baffle plate that cooperates with the opening is provided at the end of the output shaft of the telescopic motor. A buffer connecting rod is provided on the bottom surface of the weighted liquid tank. A buffer plate is provided at the end of the output shaft of the buffer connecting rod. A limiting plate that cooperates with the buffer plate is provided on one side surface of the liquid storage tank.

[0012] Furthermore, the liquid storage tank has an upper water chamber and a lower water chamber inside, with a partition between the upper and lower water chambers. The surface of the partition has a water passage groove. The upper water chamber has a movable sealing plate inside, with a small motor on one side of the movable sealing plate. The upper water chamber also has a rotary water pump inside, with a water delivery pipe at the outlet of the rotary water pump. The water delivery pipe is connected to a water inlet on one side of the weighted liquid tank.

[0013] Furthermore, a water pump is installed inside the lower water chamber, and a water supply pipe is also installed at the outlet end of the water pump. The water supply pipe is connected to one end of the connecting water pipe. A return port is opened on one side surface of the lower water chamber, and the return port is connected to an opening opened on one side bottom surface of the weighting liquid tank.

[0014] Furthermore, a handle is provided at one end of the spray gun, and a control button is provided on the surface of the handle. A water pipe is provided on one side surface of the spray gun, and one end of the water pipe is connected to one side surface of the liquid storage tank.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this solution, a support rod assembly is installed, and the sunshade top plate is connected to the connecting frame via a pivot, allowing for flexible rotation. This enables easy adjustment of the position when not in use or when support is not required, reducing space occupation. The cooperation between the storage sleeve and the support rod allows for the rapid establishment of a stable support structure when the spray gun is extended, providing upward force to the end of the spray gun and effectively reducing fatigue for workers holding the spray gun for extended periods. This advantage is particularly pronounced when irrigating large areas over long distances. Simultaneously, the setting of the limiting protrusion and the limiting frame effectively limits the storage sleeve, ensuring the stability and reliability of the support structure. This ensures that the swaying during irrigation will not affect the effectiveness of the irrigation, greatly improving the efficiency and comfort of garden irrigation work.

[0017] 2. In this solution, a weighting component is incorporated. When the spray gun is extended to its maximum length, a diversion pump transfers water from the upper water chamber into the weighting tank, increasing its weight. Through the coordination of a connecting spring and side sliding strip, the weighting tank smoothly slides down. Simultaneously, the rotation of the weighting frame causes the sunshade top to tilt upwards, providing upward force to the end of the spray gun with the help of the support rod, making it easier for workers to hold and solving the problem of difficulty in holding it over long distances. When the spray gun is shortened, the telescopic motor controls the baffle plate to rise, allowing water in the weighting tank to flow back to the lower water chamber, reducing its own weight and not affecting normal spraying. This design, which automatically adjusts the weight distribution according to different states of the spray gun, ensures smooth irrigation while fully considering the operator's experience, making the equipment more flexible and efficient.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figures 1 to 4 A garden irrigation spray gun with a spray boom, comprising:

[0025] The liquid storage tank 1 has an injection port 2 on one side surface and a shoulder strap 3 on the same side surface. A spray gun 5 is also mounted on one side of the liquid storage tank 1, with a handle 7 at one end and a control button 12 on its surface. A water pipe 6 is connected to one side surface of the spray gun 5, with one end of the water pipe 6 connected to the side surface of the liquid storage tank 1. A support mechanism is mounted on the upper surface of the liquid storage tank 1, including a strut assembly and a weighting assembly. The strut assembly includes a connecting frame 13, which is fixedly mounted on the upper surface of the liquid storage tank 1. A sunshade top plate 10 is provided on the upper surface of the connecting frame 13. A pivot is provided at the connection between the sunshade top plate 10 and the connecting frame 13. A limiting protrusion 11 is provided on the upper surface of the sunshade top plate 10. A storage sleeve 9 is provided on the upper surface of the limiting protrusion 11. A support rod 8 is provided on one side surface of the storage sleeve 9. One end of the support rod 8 is connected to one end surface of the spray gun 5. A limiting frame 14 that cooperates with the storage sleeve 9 is also provided on one side surface of the limiting protrusion 11. A weighted frame 15 is provided on the bottom surface of the limiting frame 14. A pivot is provided at the connection between the weighted frame 15 and the limiting frame 14.

[0026] During use, the operator injects liquid into the back tank 1 through the injection port 2 on one side surface of the back tank 1. The liquid first enters the upper water chamber 16 and then flows into the lower water chamber 17 through the water channel. Once the lower water chamber 17 is full, the small motor in the upper water chamber 16 is started by the operator's signal, which moves the movable sealing plate 29 to close the water channel on the partition. During operation, the operator holds the handle 7 at one end of the spray gun 5 and controls the working status of the spray gun 5 through the control button 12 on the surface of the handle 7. One end of the water pipe 6 is connected to one side surface of the back tank 1, and the other end is connected to the spray gun 5. When the water is started, water is dispensed. When pump 20 is activated, the liquid in the lower water chamber 17 is pumped by the pump 20 through the water pipe 19 and the connecting water pipe 6 into the spray gun 5, and finally sprayed out from the nozzle of the spray gun 5 to irrigate the garden plants. The control button 12 can control the start and stop of the pump 20, the power level, etc., thereby adjusting the water output and spray distance. When the spray gun 5 is extended to its longest length, in order to make it easier for the staff to hold, the water in the upper water chamber 16 is transferred into the weighted liquid tank 4 by the transfer pump 18 of the weighting component. This allows the end of the spray gun 5 to be lifted upward by the support rod 8, making it easier for the staff to hold.

[0027] The weighting assembly includes: a weighting liquid tank 4, which is disposed on one side surface of the liquid storage back box 1. The upper surface of the weighting liquid tank 4 is connected to the bottom surface of the weighting frame 15. Two side sliding strips 24 are provided on one side surface of the weighting liquid tank 4. A sliding groove is provided on the side surface of the liquid storage back box 1 to cooperate with the side sliding strips 24. A connecting spring 25 is provided on the upper surface of the side sliding strips 24. The upper surface of the connecting spring 25 is connected to the inner upper surface of the sliding groove. An opening is provided on one bottom surface of the weighting liquid tank 4. A telescopic motor 26 is disposed inside the weighting liquid tank 4. A baffle 27 that cooperates with the opening is provided at the end of the output shaft of the telescopic motor 26. A buffer connecting rod 28 is provided on the bottom surface of the weighting liquid tank 4. A buffer plate 22 is provided at the end of the output shaft of the buffer connecting rod 28. A buffer plate 22 that cooperates with the buffer plate 22 is provided on one side surface of the liquid storage back box 1. The limiting plate 23, the liquid storage back box 1 has an upper water chamber 16 and a lower water chamber 17 inside, a partition is provided between the upper water chamber 16 and the lower water chamber 17, and a water passage groove is provided on the surface of the partition. The upper water chamber 16 has a movable sealing plate 29 inside, and a small motor is provided on one side surface of the movable sealing plate 29. The upper water chamber 16 has a rotating water pump 18 inside, and a water delivery pipe 19 is provided at the outlet end of the rotating water pump 18. The water delivery pipe 19 is connected to the water inlet provided on one side surface of the weighted liquid tank 4. The lower water chamber 17 has an outlet pump 20 inside, and a water delivery pipe 19 is also provided at the outlet end of the outlet pump 20. The water delivery pipe 19 is connected to one end of the connecting water pipe 6. A return port 21 is provided on one side surface of the lower water chamber 17. The return port 21 is connected to the opening opened on one side bottom surface of the weighted liquid tank 4.

[0028] When the spray gun 5 is extended to its maximum length, the diversion pump 18 transfers water from the upper water chamber 16 into the weighted liquid tank 4, increasing the weight of the tank and forcing the connecting spring 25 to stretch. The tank then slides down the slide rail 24 within the groove. As the tank slides down, the pivot above the weighted frame 15 and the connecting frame 13 rotates, causing the sunshade 10 to tilt upwards. This creates an upward force on the far end of the spray gun 5 via the support rod 8, making it easier for the operator to hold. When the spray gun 5 is shortened, the support rod 8 retracts into the storage sleeve 9. The baffle 27 inside the weighted liquid tank 4 is raised by the telescopic motor 26, exposing the opening on the side surface of the tank and allowing water to enter the lower water chamber 17 for normal spraying. This reduces the weight of the tank and allows for normal use.

[0029] Working principle:

[0030] When in use, the staff injects liquid into the upper water chamber through the injection port. The liquid enters the lower water chamber through the water passage. After it is full, the small motor drives the movable sealing plate to close the water passage. The hand handle and control button can control the start and stop of the water pump and the power, thereby adjusting the water output and spray distance. When the water pump is started, the liquid in the lower water chamber is sprayed out from the nozzle through the water delivery pipe and the connecting water pipe for irrigation.

[0031] When the spray gun is extended to its maximum length, the diversion pump transfers water from the upper water chamber to the weighted liquid tank. The weighted liquid tank increases in weight, the connecting spring stretches, and the side slide bar slides down the slide groove, causing it to slide. The shafts at the weighted frame and connecting frame rotate, the sunshade top plate lifts up, and the support rod exerts an upward force on the end of the spray gun for easier gripping. When the spray gun is shortened, the support rod retracts, the telescopic motor raises the baffle plate, and the water in the weighted liquid tank flows back to the lower water chamber through the return port, reducing its own weight and restoring the spray gun to normal spraying operation.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
