The fixing block is fixedly installed on the surface of the closing plate away from the inner wall of the valve box. When the sleeve moves, it drives the contact rod to start moving. When the first inclined rod disengages from the first inclined block, the contact rod moves and contacts and continuously moves to push the fixing block to start moving. The movement of the fixing block drives the closing plate to start moving, and the movement of the closing plate blocks the water flow.

[0008] According to the above technical solution, the inclined surfaces of the first inclined rod and the first inclined block in contact with each other are both inclined surfaces. The contact rod contacts the fixing block, and the closing plate contacts the pipeline. By setting the inclined surface, it is ensured that the first inclined rod can smoothly push the first inclined block when moving. By the contact, it is ensured that the contact rod can drive the fixing block to move when moving. By the contact, it is ensured that the closing plate can reduce the water flow rate of the pipeline when moving; Among them, a pushing device for preventing sediment blockage and a pressure relief device for changing the pressure are arranged inside the connection box.

By setting the inclined surfaces, it is ensured that the long rod can smoothly push the inclined surface rod II when moving, and by setting the inclined surfaces, it is ensured that the inclined surface rod II can smoothly push the fixing rod when moving.

[0012] According to the above technical solution, the pressure relief device includes an air inlet head, a baffle and a connecting block. The air inlet head is fixedly installed at the bottom of the drip irrigation head. The baffle is slidably installed on the inner wall of the drip irrigation head. One end of the connecting block is fixedly installed on the top of the baffle. The other end of the connecting block is fixedly installed at the bottom of the fixing rod. When the fixing rod moves, it drives the connecting block to start moving. The movement of the connecting block drives the baffle to start moving. The movement of the baffle opens the channel between the drip irrigation head and the air inlet head. Due to the extrusion of the extrusion plate, the drip irrigation water inside the connection box flows out from the drip irrigation head. The air pressure inside the connection box is inconsistent with the outside, which easily makes it difficult for the extrusion plate to reset automatically.

[0015] The present invention provides a water-saving drip irrigation device for landscaping. It has the following beneficial effects: (1) In this invention, by moving the extrusion plate to accelerate the water flow, the water can flow out of the drip irrigation port faster, thereby increasing the water output. It can effectively ensure that water can penetrate into the soil timely and evenly, promote the growth of plants, and at the same time, the water output can be adjusted according to different soil types to adapt to the water requirements of different soils, avoiding the rapid penetration or retention of water, and thus improving the efficiency of water penetration.

[0016] (2) In this invention, by moving the closing plate to reduce the water flow pressure, the continuous pressure of the water flow on the extrusion plate can be reduced, so that the extrusion plate can quickly reset after each working cycle, which helps to improve the stability of the drip irrigation system, ensure that an accurate water flow rate can be maintained during each irrigation, and thus improve the reliability and sustainability of the system, and avoid failures caused by the extrusion plate getting stuck or unable to reset.

[0017] (3) In this invention, by using the poking rod to clean, the blockage of the drip irrigation port can be effectively prevented, the water flow can be kept unobstructed, and it is ensured that each drip irrigation port can supply water evenly and continuously, improving the irrigation efficiency. At the same time, cleaning impurities in time helps to extend the service life of the drip irrigation equipment, reduce the frequency of failures, and thus reduce the long-term maintenance cost. By moving the push ring, plant roots or other objects can be prevented from entering the drip irrigation port, ensuring the normal flow of water, which helps the drip irrigation system to perform at its best, ensuring that each plant receives water evenly, and thus achieving a better water-saving effect.

[0018] (4) In this invention, when the channel between the drip irrigation head and the air inlet head is opened, due to the inconsistent air pressure, air enters the inside of the connection box from the air inlet head to make the air pressure consistent. This helps to avoid excessive or insufficient water flow, thus maintaining a stable water flow at each drip irrigation port and avoiding problems of over-irrigation or under-irrigation. At the same time, through the injection of air, it can also help reduce the deposition of impurities in the water to a certain extent, improve the water quality in the drip irrigation system, and reduce the pollution and blockage of the drip irrigation ports.

[0019] (5) In this invention, the bottom plate moves downward to support through fixed or counterweight design, avoiding the deviation of the drip irrigation head due to water flow impact, animal activities or human trampling, ensuring that the water outlet point always aligns with the plant root area. At the same time, it provides support for the drip irrigation head, helps to fix the position of the drip irrigation device, prevents the drip irrigation head from deviating or falling off during use, and ensures the uniform distribution and continuous supply of water flow.

The motor 5 is fixedly installed on the top of the valve box 2, the reciprocating lead screw 6 is fixedly installed at the output end of the motor 5, the sleeve 7 is slidably installed on the surface of the reciprocating lead screw 6, the inclined rod 8 is fixedly installed on the circumferential surface of the sleeve 7, the elastic telescopic rod 9 is fixedly installed on the inner wall of the connection box 3, the pressing plate 10 is fixedly installed at the movable end of the elastic telescopic rod 9, and the inclined block 11 is fixedly installed on the surface of the pressing plate 10 away from the elastic telescopic rod 9. By moving the pressing plate 10 to accelerate the water flow, the speed of water flowing out from the drip irrigation port can be made faster, thereby increasing the water output, effectively ensuring that water can penetrate into the soil in a timely and uniform manner, promoting the growth of plants, and at the same time, the water output can be adjusted according to different soil types to adapt to the water requirements of different soils, avoiding excessive or stagnant water penetration, so as to improve the efficiency of water penetration.

[0024] The pressurizing device further includes a contact rod 12, an elastic telescopic rod 13, a closing plate 14, and a fixing block 15. The contact rod 12 is fixedly installed on the circumferential surface of the sleeve 7, the elastic telescopic rod 13 is fixedly installed on the inner wall of the valve box 2, the closing plate 14 is fixedly installed at the movable end of the elastic telescopic rod 13, and the fixing block 15 is fixedly installed on the surface of the closing plate 14 away from the inner wall of the valve box 2. By moving the closing plate 14 to reduce the water flow pressure, the continuous pressure of the water flow on the pressing plate 10 can be reduced, so that the pressing plate 10 can quickly reset after each working cycle, which helps to improve the stability of the drip irrigation system, ensure that an accurate water flow rate can be maintained during each irrigation, thereby improving the reliability and sustainability of the system, and avoiding failures caused by the pressing plate 10 getting stuck or unable to reset.

[0025] The inclined surfaces where the first inclined surface rod 8 and the first inclined surface block 11 are in contact with each other are both set as inclined surfaces. The contact rod 12 is in contact with the fixed block 15, and the closing plate 14 is in contact with the pipeline 1. By setting the inclined surfaces, it is ensured that the first inclined surface rod 8 can smoothly push the first inclined surface block 11 when moving. By the contact, it is ensured that the contact rod 12 can drive the fixed block 15 to move when moving. By the contact, it is ensured that the closing plate 14 can reduce the water flow velocity in the pipeline 1 when moving.

[0026] When this embodiment works: First, before starting work, the staff checks each component of the drip irrigation device. After the staff confirms that there is no problem, the drip irrigation device is installed on the pipeline 1. After the installation is completed, the device is placed at the designated position. Then, drip irrigation water is introduced into the pipeline 1. The water flow flows into the valve box 2 through the pipeline 1, then enters the connection box 3 through the valve box 2, and finally flows into the drip irrigation head 4 through the connection box 3 and flows out from the outlet of the drip irrigation head 4. When the drip irrigation device needs to increase the water output to drip irrigate the target plants, the staff manually starts the motor 5 to drive the reciprocating lead screw 6 to start rotating. The rotation of the reciprocating lead screw 6 drives the sleeve 7 to start moving. The movement of the sleeve 7 drives the first inclined surface rod 8 to start moving. The first inclined surface rod 8 moves and contacts and continuously pushes the first inclined surface block 11 to start moving towards the connection box 3. The movement of the first inclined surface block 11 drives the pressing plate 10 to start moving towards the connection box 3. The movement of the pressing plate 10 squeezes the water flow between it and the connection box 3. By accelerating the water flow through the pressing plate 10, the speed of the water flowing out from the drip irrigation port can be made faster, thereby increasing the water output, effectively ensuring that the water can penetrate into the soil timely and evenly, promoting the growth of plants. At the same time, the water output can be adjusted according to different soil types to adapt to the water requirements of different soils, avoiding the water from penetrating too fast or staying, thereby improving the efficiency of water penetration. While the sleeve 7 is moving, it drives the contact rod 12 to start moving. When the first inclined surface rod 8 disengages from the contact with the first inclined surface block 11, the contact rod 12 moves and contacts and continuously pushes the fixed block 15 to start moving. The movement of the fixed block 15 drives the closing plate 14 to start moving. The movement of the closing plate 14 blocks the water flow and reduces the water pressure. By reducing the water pressure through the closing plate 14, the continuous pressure of the water flow on the pressing plate 10 can be reduced, so that the pressing plate 10 can quickly reset after each working cycle, which helps to improve the stability of the drip irrigation system, ensure that the accurate water flow rate can be maintained during each irrigation, thereby improving the reliability and sustainability of the system, and avoiding failures caused by the pressing plate 10 getting stuck or unable to reset.

[0027] Please refer to Figures 1-8 Based on the above embodiment, in another embodiment of the present invention, a pushing device for preventing sediment blockage and a pressure relief device for changing the pressure are arranged inside the connection box 3.

[0028] The pushing device includes a long rod 161, an elastic telescopic rod three 162, an inclined surface rod two 163, an elastic telescopic rod four 164, a fixing plate 165, a poking rod 166 and a fixing rod 167.

The fixing rod 167 is fixedly installed at the bottom of the fixing plate 165. By using the poking rod 166 to clean, it can effectively prevent the drip irrigation port from being blocked, keep the water flow smooth, ensure that each drip irrigation port can supply water evenly and continuously, improve the irrigation efficiency, and at the same time clean the impurities in time, which helps to extend the service life of the drip irrigation equipment, reduce the frequency of failures, and thus reduce the long-term maintenance cost.

[0029] The pushing device further includes a sliding rod 168 and a pushing ring 169. The sliding rod 168 is fixedly installed on one side of the fixing plate 165 close to the poking rod 166.

The other end of the connecting block 173 is fixedly installed at the bottom of the fixing rod 167. By opening the channel between the drip irrigation head 4 and the air inlet head 171, due to the inconsistent air pressure, air enters the inside of the connection box 3 from the air inlet head 171 to make the air pressure consistent, which helps to avoid the water flow being too large or too small, thus keeping the stable water flow at each drip irrigation port, avoiding the problems of over-irrigation or under-irrigation, and at the same time, through the injection of air, it can also help to reduce the deposition of impurities in the water to a certain extent, improve the water quality in the drip irrigation system, and reduce the pollution and blockage of the drip irrigation port.

[0032] The pressure relief device further includes a push rod 174, a sliding column 175, a second inclined surface block 176 and a bottom plate 177. The push rod 174 is fixedly installed on the top of the baffle 172. The sliding column 175 slidably penetrates and connects to the box 3. The second inclined surface block 176 is fixedly installed on the top of the sliding column 175. The bottom plate 177 is fixedly installed on the bottom of the sliding column 175. The downward movement of the bottom plate 177 supports through a fixed or counterweight design, preventing the drip irrigation head 4 from shifting due to water flow impact, animal activities or human trampling, ensuring that the water outlet point always aligns with the plant root area, and at the same time providing support for the drip irrigation head 4, helping to fix the position of the drip irrigation device, preventing the drip irrigation head 4 from shifting or falling off during use, and ensuring the uniform distribution and continuous supply of water flow.

[0033] The surfaces of the push rod 174 and the second inclined surface block 176 that are in contact with each other are both provided with inclined surfaces. A spring is provided between the bottom plate 177 and the connection box 3. By setting the inclined surfaces, it is ensured that the push rod 174 can smoothly push the second inclined surface block 176 when moving. By setting the spring, it is ensured that the bottom plate 177 can achieve self-resetting under the action of the spring.

[0034] When this embodiment works: while the extrusion plate 10 moves, it drives the long rod 161 to start moving. The long rod 161 moves and contacts and continuously moves to push the second inclined surface rod 163 to start moving downward. The second inclined surface rod 163 moves and contacts and continuously moves to push the fixed rod 167 to start moving. The fixed rod 167 moves to drive the fixing plate 165 to start moving. The fixing plate 165 moves to drive the poking rod 166 to start moving. By using the poking rod 166 for cleaning, it can effectively prevent the drip irrigation port from being blocked, keep the water flow unobstructed, ensure that each drip irrigation port can supply water evenly and continuously, improve the irrigation efficiency, and at the same time clean the impurities in time, which helps to extend the service life of the drip irrigation equipment, reduce the frequency of failures, and thus reduce the long-term maintenance cost. While the fixing plate 165 moves, it drives the sliding rod 168 to start moving. The sliding rod 168 moves to drive the pushing ring 169 to start moving. The pushing ring 169 moves to prevent plant roots or other objects from entering the drip irrigation port, ensure the normal flow of water, help the drip irrigation system to perform at its best, and ensure that each plant receives water evenly, so as to achieve a better water-saving effect.

[0035] While the fixed rod 167 is moving, it drives the connecting block 173 to start moving. The movement of the connecting block 173 drives the baffle 172 to start moving. The movement of the baffle 172 opens the channel between the drip irrigation head 4 and the air inlet head 171. Due to the extrusion of the extrusion plate 10, the drip irrigation water inside the connecting box 3 flows out from the drip irrigation head 4. The air pressure inside the connecting box 3 is inconsistent with the outside, which easily makes it difficult for the extrusion plate 10 to reset automatically. At this time, by opening the channel between the drip irrigation head 4 and the air inlet head 171, due to the inconsistent air pressure, air enters the inside of the connecting box 3 from the air inlet head 171 to make the air pressure consistent, which helps to avoid the water flow being too large or too small, thus maintaining a stable water flow at each drip irrigation port and avoiding the problems of over-irrigation or under-irrigation. At the same time, through the injection of air, it can also help reduce the deposition of impurities in the water to a certain extent, improve the water quality in the drip irrigation system, and reduce the pollution and blockage of the drip irrigation ports. While the baffle 172 is moving, it drives the push rod 174 to start moving. The push rod 174 moves and contacts and continuously moves to push the second inclined block 176 to start moving downward. The movement of the second inclined block 176 drives the sliding column 175 to start moving downward. The movement of the sliding column 175 drives the bottom plate 177 to start moving downward. The downward movement of the bottom plate 177 is supported by a fixed or counterweight design to prevent the drip irrigation head 4 from shifting due to water flow impact, animal activities or human trampling, ensuring that the water outlet point is always aligned with the plant root area. At the same time, it provides support for the drip irrigation head 4, helps to fix the position of the drip irrigation device, and prevents the drip irrigation head 4 from shifting or falling off during use, ensuring the uniform distribution and continuous supply of water flow.
