Description

Technical Field

[0001] The invention belongs to the field of sprinkler irrigation devices, and in particular relates to a garden sprinkler irrigation device. Background Art

[0002] Sprinkler irrigation is a common way of watering plants in horticultural planting. Through the action of the pipeline system and water pressure, water is transported to the sprinkler device and then sprayed through the nozzle to water the plants. It has the advantages of water saving, environmental protection, easy automation management, and avoidance of soil erosion. The sprinkler devices currently used usually use rocker arm sprinklers for spraying and watering, but the impact force of the water column sprayed by the rocker arm sprinkler is large, and it is difficult to spray the plants within the range evenly. It is very easy for plants in some positions to be not watered but plants in some positions are knocked over by the impact of the water flow. In addition, there are usually more impurities in the irrigation water. The current irrigation device has a poor filtering effect. During long-term use, the nozzle is prone to clogging, which affects the effect of spraying and reduces the irrigation efficiency. Since the soil at the location where the sprinkler device is set is relatively soft, the fixing effect of the sprinkler device after setting is poor. After long-term use, it is easy to loosen and it is very easy to fall over in windy weather. Summary of the invention

[0003] The present invention aims to provide a gardening sprinkler device to solve the problem that the sprinkler devices currently used usually use rocker arm sprinkler heads for spraying and watering, but the impact force of the water column sprayed by the rocker arm sprinkler head is large, and it is difficult to spray the plants within the range evenly. It is very easy for plants in some positions to be not watered but plants in some positions to be tilted by the impact of the water flow. There are usually more impurities in the irrigation water. The currently used irrigation device has a poor filtering effect. During long-term use, the sprinkler head is very likely to be blocked, which affects the effect of spraying and irrigation and reduces the irrigation efficiency. Since the soil at the location where the sprinkler device is set is relatively soft, the fixing effect of the sprinkler device after setting is poor, and it is easy to become loose after long-term use, and it is very easy to fall over in windy weather. Technical problems.

[0004] To achieve the above-mentioned purpose, the specific technical scheme of a gardening sprinkler device of the present invention is as follows:

[0005] A gardening sprinkler device comprises a fixed base; a first vertical pipe is vertically arranged on the fixed base; a water supply pipe is arranged at the lower side of the first vertical pipe and is connected with the first vertical pipe; a first solenoid valve is arranged on one side of the water supply pipe; a second vertical pipe is slidably arranged in the first vertical pipe; a connecting pipe is arranged at the top of the second vertical pipe through a threaded connection and is connected; a filter is arranged in the middle of the connecting pipe; a rotating shaft is rotatably arranged in the connecting pipe and passes through the filter; an impeller is arranged at the bottom of the rotating shaft; a three-way pipe is rotatably arranged at the top of the connecting pipe; the top end of the rotating shaft passes through the inside of the connecting pipe and is fixedly connected with the three-way pipe; spray pipes are extended at both sides of the three-way pipe; and a plurality of nozzles are arranged at the lower side and end of the spray pipe.

[0006] Furthermore, the connecting pipe is provided with a storage cavity on the outside of the filter; and a plurality of scrapers are provided on the lower side of the rotating shaft close to the filter.

[0007] Furthermore, the fixed base is slidably provided with a plurality of fixed cylinders; a plurality of cone blocks are rotatably provided at the bottom of the fixed cylinder and combined into a cone; a cone core with a cone-shaped bottom is slidably provided in the fixed cylinder.

[0008] Furthermore, a sliding cavity is arranged on the outer side of the first vertical pipe; a slider is arranged on the outer side of the second vertical pipe extending and slidingly extending into the sliding cavity; water-permeable holes are arranged alternately on the slider and the sliding cavity; a water supply branch is arranged in connection with the water supply pipe and the sliding cavity; and a second solenoid valve is arranged on the water supply branch.

[0009] The gardening sprinkler irrigation device of the present invention has the following advantages: a rotating shaft and an impeller are rotatably arranged at the position of a connecting pipe, and the rotating shaft is driven to rotate by the impact of water flow on the impeller, and the three-way pipe and the sprinkler pipe are driven to rotate on the connecting pipe, so that the multiple sprinkler heads can spray and irrigate more evenly, ensuring that plants can obtain sufficient water, improving the utilization rate of water resources, and improving the irrigation efficiency; a filter screen is arranged at the position of the connecting pipe, and the filter screen is used to effectively intercept impurities in the water, so as to ensure that the water quality entering the sprinkler head is pure, thereby greatly reducing the risk of clogging; a plurality of scrapers are arranged on the lower side of the filter screen by the rotating rotating shaft, so that the scrapers can scrape the impurities filtered by the filter screen into the storage cavity during the process of rotating with the rotating shaft, so as to avoid the filter screen being blocked by impurities during long-term use, reducing the water flow rate and water pressure, and causing the sprinkler irrigation efficiency to be reduced; when setting the gardening irrigation device, a plurality of fixed cylinders are inserted into the ground through the fixed base, and then the cone core is knocked into the fixed cylinder, and the cone core is used to The core squeezes and expands multiple cone blocks that are rotatably arranged at the bottom of the fixed cylinder, thereby increasing the friction force of the fixed cylinder in the soil and the fixing effect of the device, and it is not easy to loosen and fall over during long-term use; the second solenoid valve is opened to inject water into the sliding cavity through the water supply branch, and the amount of water injected is greater than the amount of water flowing out through the water permeable hole. The pressurized water pushes the slider to slide upward in the sliding cavity until the slider fits the top of the sliding cavity and blocks the water permeable hole. The water pressure is used to form a support to raise the second vertical pipe, increase the height of the spray pipe and the nozzle, and increase the spraying area of ​​the device. When the spraying area needs to be reduced, the second solenoid valve is closed, and the slider set in the second vertical pipe slides down in the sliding cavity under the influence of gravity, and the water in it flows out through the water permeable hole to complete the operation of lowering the spray pipe and the nozzle and reducing the spraying range. The function of lifting and lowering to change the spraying range increases the use range of the spraying of the device and is more convenient for sprinkler irrigation of horticultural plants.

[0016] To better understand the purpose, structure and function of the present invention, the following further describes in detail a horticultural sprinkler irrigation device of the present invention with reference to the accompanying drawings.

[0017] As Figures 1-5 shown, a horticultural sprinkler irrigation device of the present invention includes a fixed base 1; a first vertical pipe 2 is vertically arranged on the fixed base 1; a water supply pipe 3 is arranged on the lower side of the first vertical pipe 2 and is communicated with the first vertical pipe 2; a first solenoid valve 4 is arranged on one side of the water supply pipe 3; a second vertical pipe 5 is slidably arranged in the first vertical pipe 2; a connecting pipe 6 is connected and communicated with the top of the second vertical pipe 5 by means of threading; a filter screen 7 is arranged in the middle of the connecting pipe 6; a rotating shaft 8 is rotatably arranged in the connecting pipe 6 and passes through the filter screen 7; an impeller 9 is arranged at the bottom of the rotating shaft 8; a three-way pipe 10 is rotatably arranged at the top of the connecting pipe 6; the top end of the rotating shaft 8 passes through the inside of the connecting pipe 6 and is fixedly connected with the three-way pipe 10; the two sides of the three-way pipe 10 extend to be provided with spraying pipes 11; a plurality of nozzles 12 are arranged on the lower side and the end of the spraying pipe 11.

[0018] Combined with Figures 1-5As shown, when in use, the horticultural sprinkler device is fixed at the desired sprinkler position, the first solenoid valve 4 is opened, and water is supplied to the first vertical pipe 2 and the second vertical pipe 5 through the water supply pipe 3. The water flows through the connecting pipe 6, the three-way pipe 10, and the spray pipe 11 through multiple nozzles 12 to spray the horticultural plants. During the sprinkler irrigation process, the rotating shaft 8 and the impeller 9 are rotatably arranged at the position of the connecting pipe 6. The impeller 9 is driven to rotate by the water flow impacting the impeller 9, and the three-way pipe 10 and the spray pipe 11 are driven to rotate on the connecting pipe 6, so that the multiple nozzles 12 can spray and irrigate more evenly, ensuring that the plants can obtain sufficient water, improving the utilization rate of water resources, and improving the irrigation efficiency; a filter screen 7 is arranged at the position of the connecting pipe 6, and the filter screen 7 is used to effectively intercept impurities in the water, which can ensure that the water quality entering the nozzle 12 is pure, thereby greatly reducing the risk of blockage.

[0019] The connecting pipe 6 is provided with a storage cavity 13 on the outside of the filter 7; a plurality of scrapers 14 are provided on the lower side of the filter 7 in contact with the rotating shaft 8, and the plurality of scrapers 14 are provided on the lower side of the filter 7 through the rotating shaft 8, so that the scrapers 14 can scrape the impurities filtered by the filter 7 into the storage cavity 13 during the rotation of the rotating shaft 8, so as to avoid the filter 7 being blocked by impurities during long-term use, thereby reducing the water flow rate and water pressure, and causing the sprinkler irrigation efficiency to decrease.

[0020] The fixed base 1 is slidably provided with a plurality of fixed cylinders 15; a plurality of cone blocks 16 are rotatably provided at the bottom of the fixed cylinder 15 and are combined into a cone shape; a cone core 17 with a cone-shaped bottom is slidably provided in the fixed cylinder 15. When setting up the garden irrigation device, the plurality of fixed cylinders 15 are inserted into the soil through the fixed base 1, and the fixed base 1 is fixed by using the plurality of fixed cylinders 15. The cone core 17 is then knocked into the fixed cylinder 15, and the plurality of cone blocks 16 rotatably provided at the bottom of the fixed cylinder 15 are squeezed and expanded by using the cone core 17, thereby increasing the friction force of the fixed cylinder 15 in the soil, increasing the fixing effect of the device, and preventing the device from loosening and falling over during long-term use.

[0021] A sliding cavity 18 is arranged outside the first vertical pipe 2; a slider 19 is slidably arranged inside the sliding cavity 18 by extending outward from the outside of the second vertical pipe 5; water permeable holes 20 are arranged alternately between the slider 19 and the sliding cavity 18; a water supply branch 21 is connected between the water supply pipe 3 and the sliding cavity 18; a second electromagnetic valve 22 is arranged on the water supply branch 21. When it is necessary to change the spraying range of the sprinkler device, the second electromagnetic valve 22 is opened to inject water into the sliding cavity 18 through the water supply branch 21. The amount of water injected is greater than the amount of water flowing out through the water permeable holes 20. The water with pressure pushes the slider 19 to slide upward in the sliding cavity 18 until the slider 19 fits against the top of the sliding cavity 18, blocking the water permeable holes 20, forming a support by using water pressure, raising the second vertical pipe 5, increasing the height of the spray pipe 11 and the nozzle 12, and increasing the spraying area of the device. When it is necessary to reduce the spraying area, the second electromagnetic valve 22 is closed. The slider 19 arranged on the second vertical pipe 5 slides downward in the sliding cavity 18 under the influence of gravity, and the water inside it flows out through the water permeable holes 20, completing the operation of lowering the spray pipe 11 and the nozzle 12 and reducing the spraying range. The function of being able to lift and lower to change the spraying range increases the usage range of the spraying of the device, and is more convenient for the sprinkler irrigation of horticultural plants.
