Description

Technical Field

[0001] This utility model relates to the field of automatic irrigation technology for farms, specifically an automatic irrigation device for farms. Background Technology

[0002] Automated irrigation is an irrigation method that utilizes automation technology. Through sensors, controllers, and actuators, it automatically adjusts irrigation time and water volume based on parameters such as soil moisture, crop water requirements, and climate conditions. This technology not only improves irrigation efficiency but also significantly saves water resources and reduces labor costs, making it an important component of modern agriculture.

[0003] When performing automatic irrigation, spraying equipment is often set up on the farm ground. When irrigation is needed, water is simply supplied by an external water pipe and sprayed directly from the spraying equipment. However, if the nozzles extend beyond the ground, some machinery on the farm can easily crush the nozzles, causing damage. If the nozzles are set underground, it is difficult for the water to be flushed out of the ground and sprayed to a greater distance. Therefore, it is necessary to design a spraying irrigation equipment with a telescopic structure. Utility Model Content

[0004] The purpose of this invention is to provide an automatic irrigation device for farms to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a pre-embedded pipe and a riser. An external water pipe is fixedly connected to the end of the pre-embedded pipe via a diversion pipe. A booster pump is fixed to the external water pipe. Water outlets are equidistantly opened on the pre-embedded pipe. A riser is fixed to the pre-embedded pipe at a position corresponding to the water outlets. A spray head is installed inside the riser. A fixing plate is fixed inside the riser and below the spray head. A connecting pipe is slidably connected to the fixing plate and passes through it. The upper end of the connecting pipe is rotatably connected to the spray head. The upper end of the spray head has a frustum structure, and nozzles are equidistantly arranged on its sidewalls. A telescopic assembly is installed inside the riser and below the fixing plate.

[0006] Preferably, the telescopic assembly includes a piston plate, which is slidably connected inside the riser and located below the fixed plate. The bottom of the connecting pipe passes through the middle of the piston plate and is fixedly connected to the piston plate. A sequence valve is provided inside the connecting pipe.

[0007] Preferably, a return spring is fixed to the upper end of the piston plate, and the upper end of the return spring is fixed to the bottom of the fixing plate.

[0008] Preferably, the nozzles on the outer side of the spray head are tilted upwards and in the same direction.

[0009] Preferably, a sealing sleeve is provided on the fixing plate at the connection point with the connecting pipe, and the connecting pipe passes through the sealing sleeve.

[0010] Preferably, a filter screen is fixed inside the riser and below the piston plate, a connecting rod is fixed at the upper end of the spray head, and an end plate is fixed at the upper end of the connecting rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by using water pressure to drive, the spray head can be lifted and water can be sprayed out from the nozzle. By using the upward reverse thrust of the nozzle, the spray head can be rotated to achieve the purpose of extending and rotating spraying. After spraying, the spray head can be retracted into the riser pipe by using a return spring to achieve the purpose of protecting the spray head. Attached Figure Description

[0016] 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.

[0017] Please see Figure 1-3This utility model provides a technical solution: including a pre-embedded pipe 1 and a riser pipe 2, the end of the pre-embedded pipe 1 is fixedly connected to an external water pipe 7 through a diversion pipe 6, a booster pump 71 is fixed on the external water pipe 7, water outlets 11 are equidistantly opened on the pre-embedded pipe 1, a riser pipe 2 is fixed on the pre-embedded pipe 1 at a position corresponding to the water outlets 11, a spray head 3 is installed in the riser pipe 2, a fixing plate 21 is fixed in the riser pipe 2 below the spray head 3, and a sliding connection is made on the fixing plate 21 and through the fixing plate 21. A connecting pipe 31 is rotatably connected to a spray head 3 at its upper end. The upper end of the spray head 3 is a frustum structure, and nozzles 33 are equidistantly arranged on its side wall. A telescopic component is provided inside the riser 2 and below the fixed plate 21. A sealing sleeve is provided on the fixed plate 21 at the connection point with the connecting pipe 31. The connecting pipe 31 passes through the sealing sleeve. A filter screen 22 is fixed inside the riser 2 and below the piston plate 32. A connecting rod 51 is fixed at the upper end of the spray head 3, and an end plate 5 is fixed at the upper end of the connecting rod 51.

[0018] The telescopic assembly includes a piston plate 32, which is slidably connected inside the riser 2 and located below the fixed plate 21. The bottom of the connecting pipe 31 passes through the middle of the piston plate 32 and is fixedly connected to the piston plate 32. A sequence valve is provided inside the connecting pipe 31. A return spring 4 is fixed at the upper end of the piston plate 32 and the upper end of the return spring 4 is fixed at the bottom of the fixed plate 21. The nozzles 33 on the outside of the spray head 3 are tilted upward and in the same direction.

[0019] Working principle: First, connect the entire device to an external power source. Then, use the booster pump 71 to pressurize the water in the external water pipe 7, causing it to flow through the diversion pipe 6 into each pre-embedded pipe 1, and then into the riser 2 from the outlet 11. Because a sequence valve is installed in the connecting pipe 31, the water can only pass through after the water pressure reaches a predetermined value. During this process, the water pressure will push the piston plate 32 upward, compressing the return spring 4, and simultaneously pushing the riser 2 and the spray head 3 upward, finally extending out from the upper end of the riser 2 until the water pressure reaches the predetermined value. After the value is measured, water flows into the connecting pipe 31 and sprays out from the nozzle 33 on the spray head 3. At this time, the spray head 3 extends out of the riser 2, and the nozzle 33 opens in one direction. Using the reverse force of water pressure, the spray head 3 can be pushed to rotate, so as to achieve the purpose of the spray head 3 extending and rotating to spray. After the spraying is finished, the booster pump 71 is depressurized. The piston plate 32 can be reset by the push of the return spring 4, so that the spray head 3 can be retracted into the riser 2. The upper end of the riser 2 is covered by the end plate 5 to achieve the purpose of protection.
