Description

Technical Field

[0001] This utility model belongs to the field of fruit and vegetable planting technology, and relates to a water-saving root irrigation device for fruit trees. Background Technology

[0002] During fruit tree cultivation, it is necessary to fertilize and water the trees regularly. Traditional watering methods mostly involve flood irrigation, which easily leads to soil compaction around the trees, reducing soil aeration and causing root rot. Furthermore, uneven water and fertilizer application and significant water loss due to evaporation are also problems. The current solution is to pre-bury pipes around the fruit trees for seepage irrigation, which offers advantages such as water conservation, energy saving, and convenience for field operations.

[0003] The following technical problems were found in the existing technology: The existing drip irrigation method requires the drip irrigation pipe to be buried underground. The drip irrigation pipe has seepage holes, but after long-term use, the soil is prone to clogging the seepage holes, which causes slow drip irrigation or even makes drip irrigation impossible, thus failing to achieve the desired effect and being detrimental to the growth of fruit trees. Utility Model Content

[0004] The technical problem this utility model aims to solve is that existing drip irrigation methods require burying drip irrigation pipes underground. These pipes have seepage holes, but over time, the soil can easily clog the seepage holes, resulting in slow or even no drip irrigation, failing to achieve the desired effect and thus hindering the growth of fruit trees.

[0005] This utility model discloses a water-saving fruit tree root irrigation device, comprising a water delivery pipe, an electromagnetic water valve fixed in the middle of the water delivery pipe, a pressure tank fixed at the outlet end of the water delivery pipe, a pre-embedded cylinder fixed at the lower end of the pressure tank, a limit plate fixed on the outer side of the top of the pre-embedded cylinder, multiple seepage holes evenly distributed on the outer side of the pre-embedded cylinder, an anti-clogging component provided on the inner side of the pre-embedded cylinder at a position corresponding to the seepage holes, multiple guide pipes evenly fixed on the outer side of the top of the pressure tank, the end of the guide pipe away from the pressure tank extending to the inner side of the pre-embedded cylinder, and the pressure tank and the pre-embedded cylinder being fixedly connected.

[0006] The anti-clogging component includes a fixed cylinder disposed inside the top of the pre-embedded cylinder. The top of the fixed cylinder is fixedly connected to the pressure tank. A drive screw is disposed at the lower end of the fixed cylinder. Multiple limiting cylinders are evenly arranged outside the drive screw. The limiting cylinders are slidably connected to the drive screw. Multiple connecting posts are evenly fixed outside the limiting cylinders. The end of each connecting post away from the limiting cylinder is fixedly connected to the pre-embedded cylinder. A drive disc is rotatably connected inside the limiting cylinder. Multiple anti-clogging plugs are evenly arranged inside the drive disc. A drive groove is provided at the position corresponding to the anti-clogging plug on the drive disc. The anti-clogging plug is slidably connected to the drive disc through the drive groove. The end of the anti-clogging plug is inserted into the pre-embedded cylinder through a seepage hole. The drive screw is threadedly connected to the drive disc.

[0007] The top end of the fixed cylinder extends to the inside of the pressure tank. An air bladder is fixed to the top end of the fixed cylinder. A movable piston is slidably connected to the inside of the fixed cylinder. A connecting rod is fixed to the lower end of the movable piston. The lower end of the connecting rod is fixedly connected to the drive screw. A drain hole is provided at the lower end of the pressure tank at a position corresponding to the pre-embedded cylinder.

[0008] A limiting spring is sleeved on the outside of the connecting rod. The top end of the limiting spring is fixedly connected to the moving piston, and the lower end of the limiting spring is fixedly connected to the fixed cylinder.

[0009] Two limiting discs are fixed at both ends of the middle part of the anti-blocking bolt and at the upper and lower ends of the limiting cylinder, respectively, and the limiting discs are slidably connected to the limiting cylinder.

[0010] A fixing rod is fixed to the outside of the pressure tank. A soil moisture sensor is fixed to the end of the fixing rod away from the pressure tank. A controller is fixed to the water supply pipe near the electromagnetic water valve. The controller is electrically connected to the soil moisture sensor and the electromagnetic water valve.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: through the coordinated structural design of the pressure tank, the pre-embedded cylinder and the anti-clogging component, the anti-clogging component can be controlled by the water pressure inside the pressure tank to cancel the sealing of the seepage hole during the drip irrigation operation, thus enabling the drip irrigation operation. When the electromagnetic water valve is closed, as the water pressure inside the pressure tank decreases, the anti-clogging component can be driven to seal the seepage hole, thereby preventing the soil from clogging the seepage hole and improving the practicality of the device.

[0012] Through the coordinated structural design of the electromagnetic water valve, controller, and soil moisture sensor, the soil moisture sensor can detect changes in soil moisture. When the moisture is low, it sends a signal to the controller, which then controls the electromagnetic water valve to open, allowing water to enter the pressurization tank through the water pipe and begin the seepage irrigation operation. When the moisture reaches the target level, the electromagnetic water valve can be closed, thus achieving automated seepage irrigation and effectively saving water resources.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Example 1

[0022] like Figures 1-5As shown, the device includes a water supply pipe 1, an electromagnetic water valve 2 fixed in the middle of the water supply pipe 1, a pressure tank 3 fixed at the outlet end of the water supply pipe 1, and a pre-embedded cylinder 4 fixed at the lower end of the pressure tank 3. To facilitate control of the pre-embedded depth of the pre-embedded cylinder 4, a limit plate 6 is fixed on the outer side of the top of the pre-embedded cylinder 4. To facilitate water seepage from the inside of the pre-embedded cylinder 4, multiple seepage holes 5 are evenly provided on the outer side of the pre-embedded cylinder 4. An anti-blocking component is provided on the inner side of the pre-embedded cylinder 4 at the position corresponding to the seepage holes 5. To facilitate the water source inside the pressure tank 3 to enter the interior of the pre-embedded cylinder 4, multiple guide pipes 10 are evenly fixed on the outer side of the top of the pressure tank 3. The end of the guide pipe 10 away from the pressure tank 3 extends to the inner side of the pre-embedded cylinder 4. The pressure tank 3 and the pre-embedded cylinder 4 are fixedly connected.

[0023] The anti-clogging component includes a fixed cylinder 11, which is disposed inside the top of the pre-embedded cylinder 4. The top of the fixed cylinder 11 is fixedly connected to the pressure tank 3. A drive screw 13 is disposed at the lower end of the fixed cylinder 11. Multiple limiting cylinders 12 are evenly arranged on the outer side of the drive screw 13. The limiting cylinders 12 are slidably connected to the drive screw 13. To facilitate fixing the limiting cylinders 12, multiple connecting posts 22 are evenly fixed on the outer side of the limiting cylinders 12. The end of the connecting post 22 away from the limiting cylinder 12 is fixedly connected to the pre-embedded cylinder 4. A drive disc 16 is rotatably connected to the inner side of the limiting cylinder 12. Multiple anti-clogging bolts 14 are evenly arranged on the inner side of the drive disc 16. To facilitate the movement of the anti-blocking plug 14 when the drive disc 16 rotates, a drive groove 17 is provided at the position corresponding to the anti-blocking plug 14 on the drive disc 16. The anti-blocking plug 14 is slidably connected to the drive disc 16 through the drive groove 17. The end of the anti-blocking plug 14 is inserted into the pre-embedded cylinder 4 through the seepage hole 5. In order to drive the drive disc 16 to rotate when the drive screw 13 moves, the drive screw 13 is threadedly connected to the drive disc 16. In order to facilitate the limiting of the anti-blocking plug 14, two limiting discs 15 are fixed at the middle two ends of the anti-blocking plug 14 and at the upper and lower ends of the limiting cylinder 12, respectively. The limiting discs 15 are slidably connected to the limiting cylinder 12.

[0024] The top end of the fixed cylinder 11 extends to the inside of the pressure tank 3. An air bladder 18 is fixed to the top end of the fixed cylinder 11. A movable piston 21 is slidably connected to the inside of the fixed cylinder 11. In order to facilitate the movement of the drive screw 13 when the movable piston 21 moves, a connecting rod 19 is fixed to the lower end of the movable piston 21. The lower end of the connecting rod 19 is fixedly connected to the drive screw 13. In order to facilitate the drainage of water inside the pressure tank 3, a drain hole 23 is provided at the lower end of the pressure tank 3 and at the position corresponding to the pre-embedded cylinder 4. In order to facilitate the reset of the movable piston 21, a limiting spring 20 is sleeved on the outside of the connecting rod 19. The top end of the limiting spring 20 is fixedly connected to the movable piston 21, and the lower end of the limiting spring 20 is fixedly connected to the fixed cylinder 11.

[0025] During operation, the pre-embedded cylinder 4 is first buried near the root of the fruit tree. When drip irrigation is needed, the electromagnetic water valve 2 is opened first, allowing water to enter the pressure tank 3 through the water supply pipe 1. As the water in the pressure tank 3 increases, the water pressure increases, which squeezes the air bladder 18, causing air inside the air bladder 18 to enter the fixed cylinder 11. At this time, the moving piston 21 and the connecting rod 19 are pushed downwards. When the connecting rod 19 moves, it drives the drive screw 13 to move simultaneously. When the drive screw 13 moves, the drive disc 16 is limited by the limiting cylinder 12, which drives the drive disc 16 threadedly connected to it to rotate. When the drive disc 16 rotates, under the combined action of the drive slide 17 and the limiting cylinder 12, the anti-blocking plug 14 moves towards the drive screw 13. When the anti-blocking plug 14 moves to the point where it is disengaged from the seepage hole 5, the anti-blocking plug 14 cancels its obstruction of the seepage. The water hole 5 is blocked, and the water inside the pressure tank 3 continues to increase and enters the pre-embedded cylinder 4 through the guide pipe 10, thereby seeping out through the seepage hole 5. After the water source is turned off, the water inside the pressure tank 3 will slowly flow into the pre-embedded cylinder 4 through the drain hole 23. As the water source inside the pressure tank 3 decreases, the water pressure also decreases. At this time, the moving piston 21 moves towards the pressure tank 3 under the elastic action of the limit spring 20, thereby pushing the air inside the fixed cylinder 11 into the air bag 18, and at the same time driving the drive screw 13 to move upward, thereby driving the drive disc 16 to rotate in the opposite direction, and then driving the anti-blocking plug 14 to move towards the seepage hole 5. When the anti-blocking plug 14 moves to the inside of the seepage hole 5, the seepage hole 5 can be blocked. On the one hand, the soil adhering to the inside of the seepage hole 5 is removed, and on the other hand, the soil can be prevented from blocking the seepage hole 5. Example 2

[0026] like Figure 1 As shown, a fixing rod 9 is fixed on the outside of the pressure tank 3. In order to facilitate real-time detection of soil moisture, a soil moisture sensor 8 is fixed at the end of the fixing rod 9 away from the pressure tank 3. In order to facilitate control of the opening and closing of the electromagnetic water valve 2, a controller 7 is fixed at the position of the water supply pipe 1 near the electromagnetic water valve 2. The controller 7 is electrically connected to the soil moisture sensor 8 and the electromagnetic water valve 2.

[0027] Through the coordinated structural design of the electromagnetic water valve 2, controller 7, and soil moisture sensor 8, the soil moisture sensor 8 can detect changes in soil moisture. When the moisture is low, it sends a signal to the controller 7, which then controls the electromagnetic water valve 2 to open, allowing water to enter the pressurization tank 3 through the water supply pipe 1 to begin the seepage irrigation operation. When the moisture reaches the target level, the electromagnetic water valve 2 can be closed, thus achieving automated seepage irrigation and effectively saving water resources.
