Description

Technical Field

[0001] The utility model relates to the technical field of drip irrigation, in particular to a drip irrigation device for planting crops. Background Art

[0002] Drip irrigation is a local irrigation technology that sets a capillary tube with a diameter of about 10 mm in a plastic pipe system and installs a dripper or drip pot with an orifice on the capillary tube to drip water evenly and slowly into the soil at the root of the crop in very small doses. This method can be precisely controlled according to the water requirements of the crop, achieving a small amount of multiple irrigation mode, which helps to save water resources and improve the yield and quality of crops.

[0003] When installing the existing drip irrigation device, it is necessary to use a puncher to drill holes in the plastic pipe and then install the drip irrigation device. However, directly drilling holes in the plastic pipe to install the drip irrigation device is not only laborious, but also damages the plastic pipe itself, resulting in the plastic pipe cannot be reused. In addition, the position of the drip irrigation hole cannot be changed after drilling. When the position of the drip irrigation device needs to be adjusted, it is necessary to drill holes again as needed, which is troublesome, time-consuming and labor-intensive, and reduces the flexibility and practicality of the drip irrigation device.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0005] In view of the above background technology, the prior art has the disadvantages that directly drilling holes on plastic pipes to install drippers is not only laborious, but also causes damage to the plastic pipes themselves, resulting in the insufficiency and defects of the plastic pipes that cannot be reused.

[0006] The utility model discloses a drip irrigation device for planting crops, comprising a connecting pipe, wherein the outer circumferential surface of the connecting pipe is fixedly sleeved with two connecting rings, the left side and the right side of the connecting pipe are both provided with external plastic pipes, each external plastic pipe is provided with a connecting groove inside, the inner wall of each connecting ring is respectively rotatably sleeved with the external plastic pipe through the connecting groove, the interior of the connecting pipe is fixedly connected with a fixing plate, and the interior of the fixing plate is fixedly plugged with equidistantly arranged drip irrigation pipes;

[0007] The front side of the fixed plate is fixedly connected with equidistantly arranged transverse plates, a control rod is rotatably plugged into the interior of each of the transverse plates, the outer circumferential surface of the control rod is threadedly connected with two threaded tubes, the outer circumferential surface of each of the threaded tubes is fixedly connected with a connecting plate, the bottom surface of the connecting plate is fixedly connected with a baffle, the back side of the baffle is in contact with the front side of the fixed plate, a dripper is slidably plugged into the interior of the fixed plate through a groove, the front side of the dripper is provided with equidistantly arranged drip irrigation heads, the front side of the fixed plate is fixedly connected with equidistantly arranged bottom plates, and two positioning rods are slidably plugged into the interior of each of the bottom plates.

[0008] By adopting the above scheme, since directly drilling holes on the plastic pipe to install the dripper is not only laborious, but also damages the plastic pipe itself, resulting in the plastic pipe being unable to be reused, and the position of the drip irrigation hole cannot be changed after drilling, the threaded pipe is driven to move in the relative direction by rotating the control rod, prompting the connecting plate to drive the baffle to move in the relative direction, thereby facilitating the loading and unloading and positioning of the dripper, and under the action of the baffle, the drip irrigation pipe can be shielded when the dripper is not installed, and the spring can drive the positioning rod to automatically move back to position the positioning plate by its own elastic force, thereby facilitating the installation of the dripper and increasing the stability of the dripper.

[0009] Optionally, an empty slot is provided inside the transverse plate, and the connecting plate is slidably connected to the transverse plate via the empty slot provided inside the transverse plate.

[0010] By adopting the above solution, the connection plate is restricted, and then the threaded pipe is restricted, so that the threaded pipe is prevented from rotating with the control rod, and the stability of the movement of the threaded pipe is increased.

[0011] Furthermore, a limiting ring is fixedly sleeved on the outer circumferential surface of the control rod, and the outer circumferential surface of the limiting ring is rotatably connected to the inside of the transverse plate.

[0012] By adopting the above solution, the control rod is restricted, the sliding and deviation of the control rod are avoided, the stability of the movement of the control rod is increased, and the control rod is forced to keep rotating all the time.

[0013] Furthermore, the outer circumferential surface of the control rod is provided with two sections of threaded structures, and the threaded tracks of the two sections of threaded structures on the outer circumferential surface of the control rod are in opposite directions.

[0014] By adopting the above solution, the threaded pipes on both sides can move in relative directions when the control rod rotates, and then the baffle is driven to open and close through the connecting plate, so that the drip irrigation pipe can be shielded and the drip irrigation device can be positioned conveniently.

[0015] Furthermore, two limit blocks are fixedly connected to the outer circumferential surface of the positioning rod, and the outer surface of each limit block is slidably connected to the bottom plate through a hollow groove opened inside the bottom plate.

[0016] By adopting the above solution, the positioning rod is restricted to prevent the positioning rod from rotating, thereby increasing the stability of the positioning rod movement.

[0017] Furthermore, a collar is fixedly sleeved on the outer circumferential surface of the positioning rod, a spring is fixedly connected to the outer surface of the collar, and the other end of the spring is fixedly connected to the inside of the bottom plate.

[0018] By adopting the above solution, the positioning rod can automatically move back by virtue of the elastic force of the spring itself, thereby automatically positioning the positioning plate.

[0019] Furthermore, two positioning plates are fixedly connected to the bottom surface of the drip irrigation device, the outer surface of the positioning rod is slidably plugged with the positioning plates through the empty grooves provided inside the positioning plates, and the back surface of the positioning plates is an inclined surface.

[0020] By adopting the above solution, the positioning plate is positioned by the positioning rod, which facilitates the installation of the dripper and increases the stability of the dripper. The inclined structure on the back of the positioning plate can automatically drive the positioning rod to move to both sides when the dripper is installed, avoiding movement conflicts between structures.

[0021] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0022] 1. The utility model drives the threaded tube to move in the relative direction during the rotation of the control rod, prompting the connecting plate to drive the baffle to move in the relative direction, so as to facilitate the loading and unloading and positioning of the dripper, avoid the effect of drilling holes on the plastic tube to install the dripper, and solve the problem that directly drilling holes on the plastic tube to install the dripper is not only laborious, but also causes damage to the plastic tube itself, resulting in the problem that the plastic tube cannot be reused.

[0023] 2. The utility model has a simple structure and is easy to use. It is convenient to install and disassemble the dripper. There is no need to drill holes in the plastic pipe to install the dripper, which saves manpower and avoids damage to the plastic pipe. In addition, more drippers can be installed at one time, and the dripper can be installed in a suitable position according to needs. The dripper can also be adjusted at multiple angles according to needs, thereby improving the flexibility and practicality of the drip irrigation device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following will disclose multiple embodiments of the utility model with diagrams. For the purpose of clear description, many physical details will be described together in the following description. However, it should be understood that these physical details should not be used to limit the utility model. In other words, in some embodiments of the utility model, these physical details are not necessary. In addition, for the purpose of simplifying the diagram, some conventional structures and components will be depicted in a simple schematic manner in the diagram.

[0031] See also Figure 1 - Figure 4 The utility model is a drip irrigation device for planting crops, comprising a connecting pipe 1, the outer circumferential surface of the connecting pipe 1 is fixedly sleeved with two connecting rings 2, the left and right sides of the connecting pipe 1 are provided with external plastic pipes 3, each of the external plastic pipes 3 is provided with a connecting groove 4, the inner wall of each connecting ring 2 is rotatably sleeved with the external plastic pipe 3 through the connecting groove 4, the interior of the connecting pipe 1 is fixedly connected with a fixing plate 5, and the interior of the fixing plate 5 is fixedly inserted with equidistantly arranged drip irrigation pipes 6;

[0032] In this embodiment, the external plastic pipe 3 is connected to an external water source, and water flow can be connected through the external plastic pipe 3. The water flow flows into the connecting pipe 1 through the external plastic pipe 3, and then flows out through the drip irrigation pipe 6 on the fixed plate 5. Specifically, each drip irrigation pipe 6 is provided with equidistantly arranged drip irrigation holes.

[0033] like Figure 3 As shown, the front side of the fixed plate 5 is fixedly connected with the equidistantly arranged transverse plates 7, and a control rod 8 is rotatably inserted inside each transverse plate 7. The outer circumferential surface of the control rod 8 is fixedly sleeved with a limit ring 9, and the outer circumferential surface of the limit ring 9 is rotatably connected with the inside of the transverse plate 7 to limit the control rod 8 and prevent the control rod 8 from sliding and deviating. The outer circumferential surface of the control rod 8 is threadedly connected with two threaded tubes 10, and the outer circumferential surface of each threaded tube 10 is fixedly connected with a connecting plate 11. An empty groove is provided inside the transverse plate 7, and the connecting plate 11 is slidably connected with the transverse plate 7 through the empty groove provided inside the transverse plate 7 to limit the threaded tube 10 and prevent the threaded tube 10 from rotating with the control rod 8.

[0034] The bottom surface of the connecting plate 11 is fixedly connected with a baffle 12, and the back surface of the baffle 12 contacts the front surface of the fixing plate 5. Specifically, the baffle 12 is located in front of the drip irrigation pipe 6. The outer circumferential surface of the control rod 8 is provided with two sections of threaded structures. The threaded tracks of the two sections of the threaded structures on the outer circumferential surface of the control rod 8 are in opposite directions, so that the two threaded pipes 10 are moved in opposite directions, and then the baffle 12 is driven to open and close through the connecting plate 11.

[0035] In a preferred embodiment, when the baffle 12 is closed, the drip irrigation pipe 6 is blocked to prevent water from flowing out. When the drip irrigation device 13 needs to be installed, the control rod 8 can be rotated to drive the baffle 12 to open to both sides through the threaded tube 10 and the connecting plate 11, and then the drip irrigation device 13 is inserted into the groove on the fixing plate 5, and then the control rod 8 is rotated in the opposite direction to drive the baffle 12 to move back, clamp the drip irrigation device 13, and position the drip irrigation device 13. The water flowing out of the drip irrigation hole on the drip irrigation pipe 6 will then flow into the drip irrigation device 13 and flow out through the drip irrigation head 14;

[0036] The interior of the fixed plate 5 is slidably plugged with a dripper 13 through a groove, and the front of the dripper 13 is provided with equidistantly arranged drip irrigation heads 14. The front of the fixed plate 5 is fixedly connected with an equidistantly arranged bottom plate 16, and two positioning rods 17 are slidably plugged into the interior of each bottom plate 16. The outer circumferential surface of the positioning rod 17 is fixedly connected with two limit blocks 18. The outer surface of each limit block 18 is slidably connected to the bottom plate 16 through an empty groove opened inside the bottom plate 16, so as to limit the positioning rod 17 and prevent the positioning rod 17 from rotating;

[0037] like Figure 4 As shown, the bottom surface of the dripper 13 is fixedly connected to two positioning plates 15, and the outer surface of the positioning rod 17 is slidably plugged with the positioning plate 15 through the empty groove opened inside the positioning plate 15. The back of the positioning plate 15 is an inclined surface, so that the dripper 13 can drive the positioning plate 15 to push the positioning rod 17 to move to both sides under the action of the inclined surface during installation, so as to avoid movement conflict between structures. The outer circumferential surface of the positioning rod 17 is fixedly sleeved with a collar 19, and the outer surface of the collar 19 is fixedly connected with a spring 20. The other end of the spring 20 is fixedly connected to the inside of the bottom plate 16. The elastic force of the spring 20 itself causes the positioning rod 17 to automatically move back, and automatically completes the positioning of the positioning plate 15.

[0038] In this embodiment, during the installation of the dripper 13, the positioning plate 15 on the dripper 13 will be inserted from the middle of the bottom plate 16, and the positioning plate 15 will push the positioning rod 17 to move to both sides through the inclined surface on the back side. During the movement, the positioning rod 17 will stretch the spring 20 through the collar 19. When the dripper 13 is completely installed in the groove of the fixing plate 5, the spring 20 drives the positioning rod 17 to automatically move back by its own elastic force, and inserts into the empty groove of the positioning plate 15, automatically positioning the positioning plate 15, and increasing the stability of the dripper 13;

[0039] The connecting pipe 1 can be rotated to adjust the dripper 13 at multiple angles according to specific conditions, and the dripper 13 can also be installed at a suitable position on the fixing plate 5 as required.
