Description

Technical Field

[0001] This utility model relates to the field of forestry drip irrigation technology, and in particular to a terrain-adaptive drip irrigation device for forestry planting. Background Technology

[0002] Drip irrigation uses plastic pipes to deliver water drop by drop, evenly and slowly to the soil near the crop root zone through drippers and orifices, providing localized irrigation. This keeps the soil near the crop roots at a suitable level of moisture. Drip irrigation does not damage the soil structure and is one of the most effective water-saving irrigation methods in forestry planting areas.

[0003] When existing forestry drip irrigation pipelines are laid in forestry planting areas, they follow the gradually rising terrain. Where they encounter vertical drops in elevation, vertical pipes and elbow connecting pipes are installed at the main drip irrigation pipeline. Although a filter structure is installed at the pipeline to filter out most large-diameter impurities, it cannot eliminate all impurities in the pipeline. Small particles, biological metabolites, and pipe debris remaining or generated in the upstream drip irrigation pipeline can easily rub against the elbow at this point, causing damage to the vertical pipe and reducing its service life. Therefore, we propose a terrain-adaptive drip irrigation device for forestry planting. Utility Model Content

[0004] The main purpose of this invention is to provide a terrain-adaptive drip irrigation device for forestry planting. A pre-filter mechanism is installed at the main drip irrigation pipe of the terrain-adaptive device. The relay pipe of the pre-filter mechanism connects to a section of water supply pipe at the high point of the main drip irrigation pipe in the terrain-adaptive area. After the water flows into the relay pipe, some of the water containing impurities is guided to preferentially enter the container along the inclined guide pipe. The baffles in the container reduce the force of the water flow, achieving a slow flow and allowing impurities to settle and be collected naturally. Simultaneously, the vertical guide pipe further guides residual small particles, biological metabolites, and other impurities from the upstream pipe downwards to the container, preventing excessive impurities from being directly flushed towards the bend in the main drip irrigation pipe, causing premature damage and aging. Furthermore, the support frame filter plate and U-shaped support frame in the relay pipe form a secondary filtration defense line. The filter screen of the support frame filter plate can further intercept fine impurities entering the main water flow after diversion. This dual treatment significantly reduces the impurity content entering the bend of the main drip irrigation pipe, reduces the frictional impact of impurities on the bend, effectively delays pipe wear, and extends its service life, effectively solving the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A terrain-adaptive drip irrigation device for forestry planting includes a main drip irrigation pipe and branch drip irrigation pipes. Branch drip irrigation pipes are interconnected on the outer side of the lower straight pipe of the main drip irrigation pipe. A pre-filter mechanism is also included, comprising a relay pipe, a vertical guide pipe, a container, an inclined guide pipe, a boss, a pressure cap, a support frame filter plate, and a tail cap. A relay pipe is bonded to the upper straight pipe inlet of the main drip irrigation pipe, and a vertical guide pipe is interconnected between the lower pipe body of the relay pipe and the container. An inclined guide pipe is fixedly connected to the inlet of the container, and its body is fixed below the straight pipe body of the relay pipe. A boss is integrally formed at the top of the relay pipe between the inclined guide pipe and the vertical guide pipe, and a U-shaped support frame is inserted between the boss and the relay pipe. A support frame filter plate is inserted into the U-shaped support frame, and a pressure cap is bolted to the boss above the U-shaped support frame. A tail cap is screwed onto the tail body of the container.

[0007] Furthermore, the two ends of the successor tube are integrally formed with a shrink-fit tube, and the shrink-fit tube at one end of the successor tube is inserted and bonded to the upper part of the drip irrigation main tube.

[0008] By adopting the above technical solution, the relay tube can be snapped and glued into the drip irrigation main tube for connection.

[0009] Furthermore, a vertical guide tube is fixedly connected to the lower tube of the relay tube, and the bottom tube of the vertical guide tube is vertically inserted into the top hole of the container and glued and fixed. A tail tube for screwing on the tail cap is fixedly connected to the tail opening of the container.

[0010] By adopting the above technical solution, the relay tube is connected to the container via a vertical lead tube, and then the rear of the container can be sealed by a tail-spinning tube connected to a tail-spinning cap.

[0011] Furthermore, a sealing gasket is pressed between the seat of the boss and the cover, and a bolt that passes through the sealing gasket is screwed between the cover and the boss.

[0012] By adopting the above technical solution, the gland can press against the sealing gasket and seal and lock with the boss. Then, bolts can be screwed into the gland and the boss to lock them.

[0013] Furthermore, the round-headed frame of the U-shaped support frame is inserted into the inner wall of the relay tube, and the top of the frame of the U-shaped support frame is provided with a U-shaped groove for inserting the support frame filter plate. The U-shaped support frame is embedded in the frame of the relay tube and has a through hole for water passage. The bottom plate of the support frame filter plate is provided with a round hole groove, and a filter screen is fixed in the round hole groove of the support frame filter plate.

[0014] By adopting the above technical solution, after the filter plate is inserted into the U-shaped groove of the U-shaped support frame, water can be filtered at the filter plate through the U-shaped support frame.

[0015] Furthermore, the cavity of the container has protruding stop posts;

[0016] By adopting the above technical solution, the baffles inside the container can reduce the inrush force of the water flow and slow down the flow.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention features a pre-filter mechanism installed at the top of the terrain-adaptive drip irrigation main. The relay pipe of the pre-filter mechanism is used to connect a section of water supply pipe to the high-level pipe of the top-level drip irrigation main. After the water flows into the relay pipe, some of the water containing impurities can be guided to enter the container first along the inclined guide pipe. The baffles in the container reduce the force of the water flow and achieve a slow flow, allowing the impurities to settle and be collected naturally. At the same time, the vertical guide pipe can further guide the small particles, biological metabolites and other impurities remaining in the upstream pipe downward to the container, preventing too many impurities from being directly flushed into the bend of the drip irrigation main and prematurely damaged and aged.

[0019] Furthermore, the support frame filter plate inside the relay pipe and the U-shaped support frame form a secondary filtration defense line. The filter screen of the support frame filter plate can intercept the fine impurities that enter the main water flow after diversion. The dual treatment greatly reduces the impurity content entering the bend of the drip irrigation main pipe, reduces the friction and impact of impurities on the bend, effectively delays the wear and tear of the drip irrigation main pipe, and extends its service life.

[0027] like Figure 1-5 As shown, a terrain-adaptive drip irrigation device for forestry planting includes a main drip irrigation pipe 1 and drip irrigation branch pipes 2. The branch pipes 2 are interconnected and installed on the outer side of the lower straight pipe of the main drip irrigation pipe 1. It also includes a pre-filter mechanism 3, which includes a relay pipe 4, a vertical guide pipe 6, a container 7, an inclined guide pipe 8, a protrusion 9, a pressure cap 10, a support frame filter plate 13, and a tail cap 15. The relay pipe 4 is interconnected and bonded to the upper straight pipe inlet of the main drip irrigation pipe 1, and the lower pipe body of the relay pipe 4 is interconnected with the container 7 by a vertical guide pipe. 6. An inclined guide tube 8 is fixedly connected to the inlet of the container 7, and the tube body of the inclined guide tube 8 is fixedly connected to the lower part of the straight tube body of the relay tube 4. A protrusion 9 is integrally formed at the top end of the relay tube 4 between the inclined guide tube 8 and the vertical guide tube 6, and a U-shaped support frame 12 is inserted between the seat body of the protrusion 9 and the relay tube 4. A support frame filter plate 13 is inserted in the U-shaped support frame 12, and a pressure cap 10 is locked to the protrusion 9 above the U-shaped support frame 12 by bolts. A tail cap 15 is screwed to the tail box body of the container 7.

[0028] Among them, the two ends of the relay tube 4 are integrally formed with a shrink-fit tube 5, and the shrink-fit tube 5 at one end of the relay tube 4 is inserted and bonded to the upper part of the drip irrigation main tube 1.

[0029] By adopting the above technical solution, the relay tube 4 can be snapped and glued into the drip irrigation main tube 1 for connection using the shrink-fit tube 5.

[0030] Among them, the lower tube of the relay tube 4 is connected and fixed with a vertical guide tube 6, and the bottom tube of the vertical guide tube 6 is vertically inserted into the top box hole of the container 7 and glued and fixed. The tail box opening of the container 7 is connected and fixed with a tail spiral tube 14 for screwing on the tail spiral cap 15.

[0031] By adopting the above technical solution, the relay tube 4 is interconnected with the container 7 via the vertical lead tube 6, and then the rear of the container 7 can be sealed by the tail spiral tube 14 connected to the tail spiral cap 15.

[0032] Wherein, a sealing gasket 11 is pressed between the seat body of the protrusion 9 and the cover 10, and a bolt passing through the sealing gasket 11 is screwed between the cover 10 and the protrusion 9.

[0033] By adopting the above technical solution, the gland 10 can press against the sealing gasket 11 and seal and lock with the boss 9. Then, bolts can be screwed into the gland 10 and the boss 9 for locking.

[0034] The round-headed frame of the U-shaped support frame 12 is inserted into the inner wall of the relay tube 4, and the top of the frame of the U-shaped support frame 12 is provided with a U-shaped groove for inserting the support frame filter plate 13. The U-shaped support frame 12 is embedded in the frame of the relay tube 4 and has a through hole for water passage. The bottom plate of the support frame filter plate 13 has a round hole groove, and a filter screen is fixed in the round hole groove of the support frame filter plate 13.

[0035] By adopting the above technical solution, after the filter plate 13 is inserted into the U-shaped groove of the U-shaped support frame 12, water can be filtered at the filter plate 13 after passing through the U-shaped support frame 12.

[0037] By adopting the above technical solution, the baffle 16 inside the container 7 can reduce the inrush force of the water flow inside the container and slow down the flow.

[0038] It should be noted that this utility model is a terrain-adaptive drip irrigation device for forestry planting.

The relay pipe 4 of the pre-filter mechanism 3 can be connected to the high-level pipe body of the drip irrigation main pipe 1 by means of a shrink-fit tube 5. Then, the shrink-fit tube 5 at the other end of the relay pipe 4 is connected to the pipe at the forestry high ground by means of embedding and bonding. Then, the support frame filter plate 13 is snapped with the U-shaped support frame 12, so that the U-shaped support frame 12 is snapped into the relay pipe 4 from the protrusion 9. The sealing gasket 11 is placed on the top of the protrusion 9, and then the pressure cap 10 is placed. The pressure cap 10 and the protrusion 9 are screwed in with bolts for locking and installation. Then, the tail cap 15 can be screwed into the tail tube 14 for sealing.

[0039] When drip irrigation water enters the relay pipe 4, impurities in the water first enter the collection box 7 along the inclined guide pipe 8. Then, the drip irrigation water is filtered by the support frame filter plate 13 in the U-shaped support frame 12 before entering the relay pipe 4. The filtered water flows through the relay pipe 4 into the drip irrigation main pipe 1 and is sent to the drip irrigation branch pipe 2. At the relay pipe 4, there is also a vertical guide pipe 6 to guide the impurities downward into the collection box 7 for collection, ensuring that the bend of the drip irrigation main pipe 1 is not easily damaged by the impact of impurities. After the water supply at the upstream drip irrigation main pipe 1 is stopped, the tail cap 15 is unscrewed so that the water flow can be manually cleaned from the tail pipe 14. After the bolt at the pressure cap 10 is unscrewed, the sealing gasket 11 is removed, and the U-shaped support frame 12 can be pulled away with the support frame filter plate 13. After cleaning and maintaining the support frame filter plate 13, it can be reinstalled.
