Description

Technical Field

[0001] This utility model relates to the field of agricultural seedling cultivation, and in particular to a drip irrigation device for agricultural seedling cultivation. Background Technology

[0002] An existing patent (publication number: CN216018277U) discloses an agricultural crop seedling drip irrigation device, including a water collection tank and a water pump connected by a hose on one side of the water collection tank, a drip irrigation pipe connected by a hose on the other side of the water collection tank, and an energy-saving collection component fixedly connected to the top of the water collection tank. A top plate is fixedly connected to the top of the water collection tank, and one end of several support rods is fixedly connected to the bottom of the top plate. The other ends of the support rods are fixedly connected to one side of a support member. The support member is fixedly connected to the inner top of the water collection tank, and a battery is fixedly connected to the side of the support member away from the bottom of the water collection tank. An embedding groove is provided at the top of the water collection tank, and a filter screen is installed inside the embedding groove. A flow guide sleeve is fixedly fitted on one side of the filter screen, outside the top of the water collection tank. However, the drip pipe orifice diameter of this drip irrigation device is fixed, making it impossible to adjust the drip irrigation volume according to planting needs, and improvements are needed. Summary of the Invention

[0003] This invention addresses the aforementioned shortcomings of existing technologies by providing a drip irrigation device for agricultural seedling cultivation. The device allows adjustment of the sliding pipe position by pulling a handle on the outside of the second water pipe, thereby controlling the size of the lower plug's seal on the lower drip hole and thus controlling the amount of water dripped.

[0004] The objective of this utility model is achieved through the following technical solution: A drip irrigation device for agricultural seedling cultivation includes a main delivery pipe, a valve, a first water pipe, an intermediate connecting pipe, a second water pipe, a sliding pipe, a limiting slide post, an arc-shaped buckle plate, a handle, a support base, and positioning pins. The main delivery pipe is connected to a water tank on one side. Multiple main-side branch pipes are located on both sides of the main delivery pipe. The main-side branch pipes are threadedly connected to the valve. The first water pipe is threadedly connected to the valve and is adapted to the intermediate connecting pipe. The first water pipe is inserted into the intermediate connecting pipe and rotates within it. The second water pipe is also adapted to the intermediate connecting pipe and is inserted into it, rotating within it. The first and second water pipes are threadedly connected to both ends of the intermediate connecting pipe, with the threads on both sides of the intermediate connecting pipe facing opposite directions.

[0005] The sliding pipe is adapted to the No. 2 water pipe. The sliding pipe is inserted into the No. 2 water pipe and slides inside the No. 2 water pipe. The lower part of the sliding pipe has a lower plug, the upper part of the No. 2 water pipe has an upper limit hole, and the lower part of the No. 2 water pipe has a lower drip hole. The lower plug is located above the lower drip hole, and the sliding pipe is located below the upper limit hole. Beneficial effects

[0006] 1. The main conveying pipe of this utility model is connected to a water supply tank at its end. Multiple main conveying pipes are distributed in the field to provide water for the rice seedlings. The main pipe side branches are connected to the No. 1 water pipe through valves, so that multiple channels are split on both sides of the main conveying pipe, allowing the main conveying pipe to provide water to the field ridges on both sides. The two ends of the intermediate connecting pipe are connected to the No. 1 water pipe and the No. 2 water pipe through threads. By rotating the intermediate connecting pipe, the No. 1 water pipe and the No. 2 water pipe can be moved in opposite directions, so that the No. 1 water pipe, the intermediate connecting pipe, and the No. 2 water pipe form an extension. The telescopic structure of the telescopic rod facilitates water supply adjustment for different field ridge spacing. The sliding pipe is inserted into the No. 2 water pipe. The upper part of the sliding pipe is sealed to the upper limit hole, and the lower plug is sealed to the lower drip hole. The limiting sliding column passes through the upper limit hole and connects to the sliding pipe. The upper limit hole positions the sliding pipe axially. The horizontal position of the sliding pipe can be moved by moving the upper limit hole. The position of the sliding pipe can be adjusted by pulling the handle on the outside of the No. 2 water pipe, thereby controlling the size of the lower plug sealing the lower drip hole and thus controlling the amount of water dripped.

[0007] 2. The support base of this utility model is fixed to the ground by positioning pins. The No. 2 water pipe is attached to the upper arc-shaped support plate. The support base supports the No. 2 water pipe, preventing the lower part of the No. 2 water pipe from directly contacting the ground during use, which would block the drip hole due to soil blockage, thus ensuring the device's operation. The main pipeline is connected to the water supply tank and is distributed in multiple sets in the field, directly supplying water to the seedlings in the core planting area. Through the branch pipes and valves on the main pipeline side, multiple channels are used to divert water on both sides of the main pipeline, simultaneously covering crops around the field ridges, eliminating irrigation blind spots and ensuring that all seedlings in the field receive a stable water source. The diversion pipeline adopts a threaded telescopic structure composed of the No. 1 water pipe, the intermediate connecting pipe, and the No. 2 water pipe. The length of the pipeline can be adjusted by rotating the intermediate connecting pipe, precisely adapting to different field ridge spacing and row spacing, without the need to replace with special pipes. It is suitable for various planting layouts such as terraced fields and contiguous farmland, reducing equipment adaptation costs. Attached Figure Description

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments: Example 1: A drip irrigation device for agricultural seedling cultivation includes a main delivery pipe 01, a valve 03, a first water pipe 04, an intermediate connecting pipe 05, a second water pipe 06, a sliding pipe 09, a limiting sliding column 11, an arc-shaped buckle plate 12, a handle 13, a support base 14, and positioning pins 15. The main delivery pipe 01 is connected to a water tank on one side and to a water supply tank at one end. Multiple main delivery pipes 01 are distributed in the field to provide water for the seedlings. Each main delivery pipe 01 has multiple branch pipes 02 on both sides, which are threadedly connected to the valve 03. The first water pipe 04 is also threadedly connected to the valve 03. The branch pipes 02 on the sides of the main delivery pipe 01 are connected to the first water pipe 04 via valves 03, thus diverting multiple channels on both sides of the main delivery pipe 01 to provide water to the field ridges on both sides. Corresponding to the intermediate connecting pipe 05, water pipe 04 is inserted into the intermediate connecting pipe 05 and rotates within it. Water pipe 06 is also inserted into the intermediate connecting pipe 05 and rotates within it. Water pipes 04 and 06 are connected to both ends of the intermediate connecting pipe 05 via threads. The threads on both sides of the intermediate connecting pipe 05 face opposite directions. Both ends of the intermediate connecting pipe 05 are connected to water pipes 04 and 06 via threads. By rotating the intermediate connecting pipe 05, water pipes 04 and 06 can move towards each other or in opposite directions, forming a telescopic pipe. The telescopic structure of this telescopic rod facilitates water supply adjustments for different field ridge spacing.

[0014] Example 2: The sliding pipe 09 of this utility model is adapted to the second water pipe 06. The sliding pipe 09 is inserted into the second water pipe 06 and slides inside the second water pipe 06. The lower part of the sliding pipe 09 has a lower plug 10, the upper part of the second water pipe 06 has an upper limit hole 08, and the lower part of the second water pipe 06 has a lower drip hole 07. The lower plug 10 is located above the lower drip hole 07, and the sliding pipe 09 is located below the upper limit hole 08. The upper part of the sliding pipe 09 blocks the upper limit hole 08, and the lower plug 10 blocks the lower drip hole 07.

[0015] Example 3: The limiting slide post 11 of this utility model is adapted to the upper limit hole 08. The limiting slide post 11 is inserted into the upper limit hole 08 and slides within the upper limit hole 08. The lower part of the limiting slide post 11 is connected to the sliding pipe 09, and the upper part of the limiting slide post 11 is connected to the arc-shaped buckle plate 12. The inner side of the arc-shaped buckle plate 12 is in contact with the outer side of the second water pipe 06. The upper part of the arc-shaped buckle plate 12 has a handle 13. The limiting slide post 11 passes through the upper limit hole 08 and connects to the sliding pipe 09. The upper limit hole 08 axially positions the sliding pipe 09. The horizontal position of the sliding pipe 09 can be moved by moving the upper limit hole 08. The position of the sliding pipe 09 can be adjusted by pulling the handle 13 on the outside of the second water pipe 06, thereby controlling the size of the lower plug 10 blocking the lower drip hole 07, and thus controlling the amount of water dripping.

[0016] Example 4: The support base 14 of this utility model has an upper arc-shaped support plate 16 on its upper part. The lower part of the second water pipe 06 is adapted to the upper arc-shaped support plate 16 and is in close contact with the upper arc-shaped support plate 16. The upper arc-shaped support plate 16 has a relief groove 17. The lower surface of the support base 14 is in close contact with the ground. The lower part of the support base 14 has two sets of positioning pins 15. The positioning pins 15 are inserted into the ground, and the support base 14 is fixed to the ground by the positioning pins 15. The second water pipe 06 is in close contact with the upper arc-shaped support plate 16. The support base 14 supports the second water pipe 06, preventing the lower part of the second water pipe 06 from directly contacting the ground when the device is in use, and preventing the soil on the ground from clogging the drip hole 07, thus ensuring the use of the device. The main pipeline 01 connects to the water supply tank and is distributed in multiple sets across the fields, directly supplying water to the seedlings in the core planting area. Through branch pipes 02 and valves 03 on the main pipeline side, multiple channels are used to divert water from both sides of the main pipeline, simultaneously covering crops around the field ridges, eliminating irrigation blind spots and ensuring all seedlings in the field receive a stable water source. The diversion pipelines employ a threaded telescopic structure consisting of a No. 1 water pipe 04, an intermediate connecting pipe 05, and a No. 2 water pipe 06. Rotating the intermediate connecting pipe 05 adjusts the pipe length, precisely adapting to different field ridge spacing and row spacing without requiring replacement with dedicated pipes. This adapts to various planting layouts such as terraced fields and contiguous farmland, reducing equipment adaptation costs.

[0017] Example 5: The installation steps of this utility model are as follows: First, insert the sliding pipe 09 into the second water pipe 06. Then, pass the limiting sliding column 11 through the upper limit hole 08 and connect it to the sliding pipe 09. Connect the upper part of the limiting sliding column 11 to the arc-shaped buckle plate 12. Connect the upper part of the arc-shaped buckle plate 12 to the handle 13. Connect the second water pipe 06 to the intermediate connecting pipe 05 through a thread. Connect the first water pipe 04 to the intermediate connecting pipe 05 through a thread. Connect the first water pipe 04 to the valve 03 through a thread. Connect the main pipe side branch pipe 02 to the valve 03 through a thread.

[0018] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
