Description

Technical Field

[0001] The utility model relates to the technical field of irrigation equipment, in particular to water-saving irrigation and fertilization equipment. Background Art

[0002] Orchard irrigation and fertilization is an important part of fruit tree planting. In order to provide water and nutrients for the fruit trees in the orchard, fruit farmers usually use drip irrigation belts or drip irrigation pipes for fertilization and irrigation. Its principle is to mix water and fertilizer through a mixing device and then transport the mixed water and fertilizer along the drip irrigation belt laid in the orchard through high pressure, and use small capillary tubes to irrigate the fruit trees at fixed points to prevent water from being lost to a position far away from the fruit trees, thereby achieving the purpose of water-saving irrigation. The Chinese patent announcement number CN210226451U discloses a The garden water-saving irrigation pipe comprises a main water pipe, a branch pipe arranged above the main water pipe and connected thereto, and a rotating head arranged at the top end of the branch pipe. A rotation indicating device is arranged above the rotating nozzle. The rotation indicating device comprises a base detachably connected to the rotating nozzle, a connecting rod vertically arranged above the base, a mounting seat and a mounting cap arranged above the connecting rod, a connecting ring rotatably arranged between the mounting seat and the mounting cap, and a plurality of indicating plates arranged around the connecting rod. The rotating indicating device has the advantages of prompting the nozzle position, being stable in use, and being highly practical. When the garden water-saving irrigation pipe is used for irrigating and fertilizing fruit trees, a replaceable flow stabilizer and small capillary tubes with openings at both ends are usually installed on the drip irrigation belt for irrigation and fertilizing of the fruit trees. Since the small capillary tubes are placed outdoors for a long time and close to the soil, there is no protective mechanism to protect the water outlets of the small capillary tubes, which has the risk of blockage. In addition, severe weather such as rain, ice and snow drive the soil to be entrained on the surface of the small capillary tubes. The small capillary tubes are hollow inside, which has the risk of crushing the small capillary tubes, shortening the service life of the small capillary tubes. Therefore, the present application proposes a water-saving irrigation and fertilization equipment. Utility Model Content

[0003] The utility model aims to solve the problem that, when irrigating and fertilizing fruit trees, a replaceable flow stabilizer and small capillary tubes with openings at both ends are usually installed on a drip irrigation belt for irrigating and fertilizing fruit trees. Since the small capillary tubes are placed outdoors for a long time and close to the soil, there is no protective mechanism to protect the water outlets of the small capillary tubes, which has the risk of blockage. In addition, inclement weather such as rain, ice and snow drive the soil to be entrained on the surface of the small capillary tubes, and the small capillary tubes are hollow inside, which has the risk of crushing the small capillary tubes, thereby shortening the service life of the small capillary tubes. The utility model provides a water-saving irrigation and fertilization device.

[0004] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0005] A water-saving irrigation and fertilization device comprises a flow stabilizer and a small capillary tube installed on the flow stabilizer, wherein a water inlet hole is provided on the small capillary tube, a sliding mechanism for automatically opening and closing the water inlet hole is installed on the bottom side of the small capillary tube, a connecting guide rod is installed on the sliding mechanism, and a rotating mechanism for opening and closing an irrigation channel is installed on the connecting guide rod. When irrigating and fertilizing fruit trees through a drip irrigation belt, water pressure drives the sliding mechanism to slide on the small capillary tube to open the water inlet hole, and water and fertilizer stabilized by the flow stabilizer enter the small capillary tube through the water inlet hole. At the same time, the sliding mechanism drives the connecting guide rod to slide during the movement process, and the sliding of the connecting guide rod drives the rotating mechanism to rotate on the small capillary tube, so that the water flow in the small capillary tube can flow out for irrigation. After the irrigation is completed, the water pressure stops, the sliding mechanism automatically resets, and at the same time drives the rotating mechanism to automatically reset, so as to protect the small capillary tube from being blocked by soil blocks, and at the same time, the small capillary tube is still filled with water, so as to prevent the small capillary tube from being crushed by soil due to bad weather, thereby extending the service life of the small capillary tube.

[0006] Furthermore, the sliding mechanism includes a guide column, which is installed on the small capillary tube, and a limit block is installed on the guide column. A connecting ear plate is slidably installed on the guide column, and the connecting ear plate is in contact with the limit block. A sliding hole is opened on the connecting ear plate, and the guide column is slidably installed in the sliding hole. A pressure plate is installed on the connecting ear plate, and the pressure plate is adapted to the water inlet hole. The connecting guide rod is installed on the pressure plate. The water pressure impacts the pressure plate covering the water inlet hole through the flow stabilizer, so that the pressure plate and the connecting ear plate slide on the guide column to open the water inlet hole, so that water flows into the small capillary tube and after the water pressure stops, the pressure plate automatically resets to block the water inlet hole to prevent the water in the small capillary tube from flowing back.

[0007] Furthermore, a return spring is movably sleeved on the guide column, one end of the return spring is mounted on the connecting ear plate, and the other end of the return spring is mounted on the small capillary tube. Through the setting of the return spring, the return spring is stretched when the pressure plate is opened due to water pressure impact. When the water pressure stops, the return spring drives the pressure plate to reset under the action of the return elastic force of the return spring, thereby achieving the function of blocking the water inlet hole.

[0008] Furthermore, a sealing gasket is installed on the pressure plate, which is adapted to the water inlet and is made of rubber material. The setting of the sealing gasket increases the contact tightness between the pressure plate and the small capillary tube, prevents water backflow, and improves the scientificity and practicality of the structure.

[0009] Furthermore, the rotating mechanism includes an arc-shaped baffle plate, which is rotatably mounted on the small capillary tube. A water outlet is provided on the small capillary tube, and the water outlet is matched with the arc-shaped baffle plate. A connecting plate is installed on the arc-shaped baffle plate, and a rotating ring is installed on the connecting plate. The rotating ring is rotatably mounted on the connecting guide rod. When the pressure plate moves, the rotating ring is driven to rotate through the connecting guide rod. When the rotating ring rotates, the arc-shaped baffle plates on both sides are driven to rotate on the small capillary tube through the connecting plate to open the water outlet, thereby facilitating the outflow of water for irrigation, and when the pressure plate is reset, the arc-shaped baffle plate is driven to automatically close the water outlet for protection.

[0010] Furthermore, a limiting arc block is installed on the arc baffle, a rotation groove is opened on the small capillary tube, the limiting arc block is slidably installed in the rotation groove, and the rotation groove cooperates with the limiting arc block to limit the movement of the limiting arc block, and the limiting arc block can and can only rotate on the small capillary tube.

[0011] Furthermore, an elliptical slide groove is provided on the rotating ring, and a brake shaft block is installed on the connecting guide rod. The brake shaft block is slidably installed in the elliptical slide groove. Through the cooperation and restriction of the brake shaft block and the elliptical slide groove, the rotating ring is driven to rotate on the connecting guide rod when the connecting guide rod slides, thereby realizing the rotation of the arc baffle to open and close the water outlet.

[0012] The beneficial effects of the utility model are as follows:

[0013] 1. The utility model, through the arrangement of the arc-shaped baffle plate, the pressure plate and the like, realizes that when irrigating fruit trees, the water pressure drives the pressure plate to slide in the small capillary tube to open the water inlet hole, and at the same time drives the arc-shaped baffle plate to rotate to open the water outlet, and irrigates through the water outlets on both sides. After the irrigation is completed, the pressure plate resets and closes the water inlet hole under the reset elastic force of the reset spring, and at the same time drives the arc-shaped baffle plate to rotate and close the water outlet, so that water is retained inside the small capillary tube to prevent it from being crushed. At the same time, the arc-shaped baffle plate protects the water outlet to prevent soil blocks from entering and blocking the small capillary tube.

[0014] 2. The utility model, through the arrangement of the water outlets, realizes that during water irrigation, water flows out through the water outlets on both sides to irrigate the surroundings of the fruit trees, thereby preventing direct impact on the fruit trees, causing the seedlings to tilt and die, and improving the practicality and scientificity of the structure.

When irrigating and fertilizing fruit trees through a drip irrigation belt, the water pressure drives the sliding mechanism 4 to slide on the small capillary tube 2 to open the water inlet hole 3, and the water and fertilizer after being stabilized by the flow stabilizer 1 enter the small capillary tube 2 through the water inlet hole 3. At the same time, When the sliding mechanism 4 slides, it will drive the connecting guide rod 5 to slide. The sliding of the connecting guide rod 5 will drive the rotating mechanism 6 to rotate on the small capillary tube 2, so that the liquid in the small capillary tube 2 flows out to irrigate the fruit trees. After the irrigation is completed, the water pressure stops, the sliding mechanism 4 automatically resets and drives the rotating mechanism 6 to automatically reset, which can effectively prevent external soil from entering the small capillary tube 2 to form soil blocks and then block the small capillary tube 2, thereby achieving effective protection for the small capillary tube 2. At the same time, it can also ensure that the small capillary tube 2 is filled with water to prevent the external soil from crushing the small capillary tube 2 in severe weather conditions, thereby extending the service life of the small capillary tube 2.

[0028] Reference Figure 1-6 In the utility model, the sliding mechanism 4 includes a guide column 401, which is installed on the small capillary 2, and a limit block 402 is installed on the guide column 401.

The external water flows into the small capillary 2 through the water inlet hole 3. When the external water flow pressure stops inputting, the pressure plate 405 automatically resets to block the water inlet hole 3, thereby preventing the water flow in the small capillary 2 from flowing back.

Through the setting of the return spring 406, when the pressure plate 405 is opened due to water pressure impact, the return spring 406 is stretched. When the water pressure stops, the return spring 406 drives the pressure plate 405 to reset under the action of the return elastic force, thereby achieving the function of blocking the water inlet hole 3.

When the pressure plate 405 moves, the connecting guide rod 5 drives the rotating ring 604 to rotate. When the movable ring 604 rotates, the arc-shaped baffles 601 on both sides are driven to rotate on the small capillary tube 2 through the connecting plate 603, thereby opening the water outlet 602. At this time, the water in the small capillary tube 2 flows out through the water outlet 602 to irrigate the fruit trees. When the pressure plate 405 is reset, the connecting guide rod 5 drives the arc-shaped baffle 601 to rotate, thereby automatically closing the water outlet 602 to prevent external soil from entering the small capillary tube 2 through the water outlet, thereby achieving effective protection for the small capillary tube 2.

The brake shaft block 608 is slidably installed in the elliptical slide groove 607. Through the cooperation restriction of the brake shaft block 608 and the elliptical slide groove 607, the rotating ring 604 is driven to rotate on the connecting guide rod 5 when the connecting guide rod 5 slides, and then when the arc baffle 601 rotates, the water outlet 602 is opened or closed.

[0034] In summary, when the fruit trees are irrigated and fertilized by the drip irrigation belt, the water pressure drives the sliding mechanism 4 to slide on the small capillary tube 2, thereby opening the water inlet hole 3, and the water and fertilizer stabilized by the flow stabilizer 1 enter the small capillary tube 2 through the water inlet hole 3. At the same time, when the sliding mechanism 4 moves, it will drive the connecting guide rod 5 to slide, and the sliding of the connecting guide rod 5 drives the rotating mechanism 6 to rotate on the small capillary tube 2 to open the water outlet 602, so that the water flow in the small capillary tube 2 can flow out from the water outlet 602 to irrigate the fruit trees. After the irrigation is completed, the water pressure stops, the sliding mechanism 4 automatically resets and drives the rotating mechanism 6 to automatically reset, which can effectively prevent external soil from entering the small capillary tube 2 to form soil blocks and then block the small capillary tube 2, thereby achieving effective protection for the small capillary tube 2. At the same time, it can also ensure that the small capillary tube 2 is filled with water to prevent the external soil from crushing the small capillary tube 2 in severe weather conditions, thereby extending the service life of the small capillary tube 2.

[0035] In this embodiment, water pressure impacts the pressure plate 405 covering the water inlet hole 3 through the flow stabilizer 1, thereby driving the pressure plate 405 and the connecting ear plate 403 to slide on the guide column 401, so that the water inlet hole 3 is opened, and water flows into the small capillary tube 2 through the water inlet hole 3; after the water pressure stops, the pressure plate 405 automatically resets to block the water inlet hole 3, thereby preventing the water flow in the small capillary tube 2 from flowing back; through the setting of the reset spring 406, the reset spring 406 is stretched when the pressure plate 405 is opened due to the impact of water pressure, and when the water pressure stops, the reset spring 406 drives the pressure plate 405 to reset under the action of the reset elastic force, thereby achieving the function of blocking the water inlet hole 3; through the setting of the sealing gasket 407, the contact tightness between the pressure plate 405 and the small capillary tube 2 is increased, water flow backflow is prevented, and the scientific nature and safety of the structure are improved. Practicality: When the pressure plate 405 moves, the connecting guide rod 5 drives the rotating ring 604 to rotate. While the rotating ring 604 rotates, the connecting plate 603 drives the arc baffles 601 on both sides to rotate on the small capillary tube 2, so that the water outlet 602 is opened, and water flows out through the water outlet 602 to irrigate the fruit trees. When the pressure plate 405 is reset, the connecting guide rod 5 drives the arc baffle 601 to move so that the water outlet 602 is automatically closed to protect the small capillary tube 2. The rotating groove 606 cooperates with the limiting arc block 605 to limit the movement of the limiting arc block 605, so that the limiting arc block 605 can and can only rotate on the small capillary tube 2.
