Description

Technical Field

[0001] This utility model relates to the field of farmland irrigation sprinkler technology, specifically to an adjustable farmland water-saving irrigation sprinkler. Background Technology

[0002] In the agricultural production system, water conservancy is crucial for stable development. Farmland irrigation, as the core manifestation of water conservancy in agriculture, is of paramount importance. Water is a key element in crop physiological processes, participating in photosynthesis, respiration, and other processes, and serving as a carrier for nutrient absorption and transport. Water conservancy workers ensure the supply of irrigation water for farmland by rationally allocating water resources. Irrigation also regulates soil temperature, maintains soil structure, and improves the soil environment. Irrigation facilities deliver water to farmland, and irrigation sprinklers, as key equipment for precision irrigation, can efficiently utilize water resources, reduce waste, and improve irrigation efficiency when properly configured.

[0003] However, the height of existing irrigation sprinklers is fixed, and they usually need to be adjusted manually or with additional equipment. They cannot automatically adjust the irrigation range continuously during the irrigation process. For some large and irregularly shaped areas, multiple sprinklers may need to be installed to meet the irrigation needs, but this may result in some irrigation blind spots or repeated irrigation in some areas. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an adjustable farmland water-saving irrigation nozzle, which can effectively solve the problem that the existing technology cannot continuously and automatically adjust the irrigation range during the irrigation process.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides an adjustable water-saving irrigation nozzle for farmland, including a water collection tank. The inlet of the water collection tank is connected to an external water injection pipe. A water collection pipe is fixedly connected to the top of the water collection tank. A connecting pipe is airtightly and slidably connected to the inner wall of the water collection pipe. A spray head is fixedly connected to the top of the connecting pipe. A water pump is fixedly connected to the inner top wall of the water collection tank. A water pump is fixedly connected to a water pump pipe at its pumping end. The other end of the water pump pipe extends to the inner bottom of the water collection tank. The water pump's pumping end and the water outlet end are connected to the inside of the water collection pipe.

[0007] According to the above-mentioned adjustable farmland water-saving irrigation nozzle, a water collection cover is fixedly connected to the top of the water collection tank, and the water collection pipe is located inside the water collection cover. Multiple water inlets are opened at the top of the water collection tank, and the water inlets are connected to the water collection cover.

[0008] According to the above-mentioned adjustable farmland water-saving irrigation nozzle, the outer wall of the water collection pipe is provided with multiple water outlets, the inner wall of the water collection pipe is provided with two symmetrical moving grooves, the inner wall of the moving grooves is slidably connected with sliding blocks, a first spring is provided between the moving grooves and the sliding blocks, the two sliding blocks are fixedly connected with a blocking ring, the outer wall of the blocking ring is provided with a connecting port, and the size of the connecting port is the same as the size of the water outlets.

[0009] According to the above-mentioned adjustable farmland water-saving irrigation nozzle, a second spring is fixedly connected to the bottom wall of the water collection pipe and the bottom end of the connecting pipe. Two symmetrical connecting rods are fixedly connected to the inner wall of the water collection pipe. A rotating wheel is rotatably connected to the outer wall of the connecting rod. A traction rope is fixedly connected to the bottom end of the connecting pipe. The traction rope passes under the rotating wheel and is fixedly connected to the bottom end of the blocking ring.

[0010] According to the above-mentioned adjustable farmland water-saving irrigation nozzle, a drain outlet is provided on the outer wall of the water collection pipe near the bottom end. Two symmetrical sliding grooves are provided on the outer wall of the water collection pipe. A slider is slidably connected to the inner wall of the sliding groove. An arc-shaped baffle is fixedly connected to the bottom end of the slider. The arc-shaped baffle is used to block the drain outlet.

[0011] According to the above-mentioned adjustable farmland water-saving irrigation nozzle, a pull plate is fixedly connected to the top of the slider, and a pull block and a push block are fixedly connected to the outer wall of the pull plate. An extension plate is fixedly connected to the bottom of the spray head, and a connecting block is fixedly connected to the outer wall of the extension plate. The top and bottom of the connecting block are intermittently in contact with the bottom of the pull block and the top of the push block, respectively.

[0012] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0013] 1. After the water pump draws water into the collection pipe, the water flow impacts the connecting pipe, causing it to move upward under the action of the second spring. At the same time, the traction rope pulls the blocking ring downward, reducing the overlap area between the connecting port and the outlet, thus reducing drainage. The water pressure pushes the connecting pipe to continue moving upward, raising the sprinkler head and expanding the irrigation range. When the sprinkler head is almost at the top, the pull plate moves the arc-shaped baffle plate upward, and water is discharged from the drain outlet. The water pressure drops, and the connecting pipe and sprinkler head fall back under the elastic force of the second spring. During the fall, the traction rope loosens, and the blocking ring moves upward under the action of the first spring, increasing the overlap area between the connecting port and the outlet, thus slowing down the descent speed. After returning to the initial position, the cycle repeats, achieving automatic adjustment.

[0014] 2. Existing sprinklers require multiple sprinklers for large and irregularly shaped areas, which may result in irrigation blind spots or repeated irrigation in some areas. This adjustable sprinkler expands the irrigation range by automatically adjusting the height of the sprinkler head, which can more effectively cover larger and irregular areas, reducing irrigation blind spots and repeated irrigation. This is achieved by automatically adjusting the height of the sprinkler head and the irrigation range, thus allocating irrigation water more rationally and achieving better irrigation results.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Example: Refer to Figures 1 to 3 An adjustable water-saving irrigation nozzle for farmland includes a water collection tank 1, with an inlet 8 of the water collection tank 1 connected to an external water injection pipe. A water collection pipe 2 is fixedly connected to the top of the water collection tank 1, and a connecting pipe 3 is airtightly slidably connected to the inner wall of the water collection pipe 2. A spray head 4 is fixedly connected to the top of the connecting pipe 3. A water pump 5 is fixedly connected to the inner top wall of the water collection tank 1, and a water pump 6 is fixedly connected to the water pump 5. The other end of the water pump 5 extends to the inner bottom of the water collection tank 1, and the water pump 5's outlet end is connected to the inside of the water collection pipe 2.

[0023] The top of the water collection tank 1 is fixedly connected to a water collection cover 7, and the water collection pipe 2 is located inside the water collection cover 7. The top of the water collection tank 1 has multiple water inlets 8, and the water inlets 8 are connected to the water collection cover 7.

[0024] The outer wall of the water collection pipe 2 has multiple outlets 9, and the inner wall of the water collection pipe 2 has two symmetrical moving grooves 10. The inner wall of the moving groove 10 is slidably connected to a sliding block 11. A first spring 26 is provided between the moving groove 10 and the sliding block 11. The two sliding blocks 11 are fixedly connected to a blocking ring 12. The outer wall of the blocking ring 12 has a connecting port 13, and the size of the connecting port 13 is the same as the size of the outlets 9.

[0025] A second spring 27 is fixedly connected to the bottom wall of the water collection pipe 2 and the bottom end of the connecting pipe 3. Two symmetrical connecting rods 14 are fixedly connected to the inner wall of the water collection pipe 2. A rotating wheel 15 is rotatably connected to the outer wall of the connecting rod 14. A traction rope 16 is fixedly connected to the bottom end of the connecting pipe 3. The traction rope 16 passes under the rotating wheel 15 and is fixedly connected to the bottom end of the blocking ring 12.

[0026] The outer wall of the water collection pipe 2 near the bottom has a drain outlet 17. The outer wall of the water collection pipe 2 has two symmetrical sliding grooves 18. The inner wall of the sliding groove 18 is slidably connected to a slider 19. The bottom end of the slider 19 is fixedly connected to an arc-shaped baffle 20, which is used to block the drain outlet 17.

[0027] A pull plate 21 is fixedly connected to the top of the slider 19. Pull blocks 22 and push blocks 23 are fixedly connected to the outer wall of the pull plate 21. An extension plate 25 is fixedly connected to the bottom of the spray head 4. A connecting block 24 is fixedly connected to the outer wall of the extension plate 25. The top and bottom of the connecting block 24 are intermittently in contact with the bottom of the pull block 22 and the top of the push block 23, respectively.

[0028] The working principle of this utility model is as follows:

[0029] When irrigation is needed, the water pump 5, which is fixedly connected to the top wall of the water collection tank 1, is started. The pumping end of the pump 5 extends to the bottom of the water collection tank 1 through the pumping pipe 6, drawing water out of the water collection tank 1 and delivering it to the inside of the water collection pipe 2 through the pumping end of the pump 5, thus completing the transfer of water source from the water collection tank 1 to the water collection pipe 2, providing a power source for subsequent irrigation spraying.

[0030] When the water pump 5 draws water into the collection pipe 2, the water flow impacts the connecting pipe 3, which is pushed upward. Due to the presence of the second spring 27, the connecting pipe 3 will move upward a certain distance. As the connecting pipe 3 moves upward, the traction rope 16 pulls the blocking ring 12 downward (because in the initial state, the connecting port 13 in the blocking ring 12 coincides with the outlet 9). As the blocking ring 12 moves downward, the overlapping area between the connecting port 13 and the outlet 9 gradually decreases, so the water discharged from the outlet 9 becomes less and less. At this time, the water pressure in the collection pipe 2 continues to act on the connecting pipe 3, pushing the connecting pipe 3 to overcome the elastic force of the second spring 27 and continue to move upward, thereby allowing the sprinkler head 4 to reach a higher position and expand the irrigation range.

[0031] As the connecting pipe 3 moves the spray head 4 to its highest point, the pull plate 21 below the spray head 4 pulls the connecting block 24 upwards, which in turn pulls the pull block 22 upwards, thereby pulling the arc-shaped baffle 20 upwards. This causes the water in the collecting pipe 2 to be discharged from the drain outlet 17, and the water pressure in the collecting pipe 2 drops accordingly. Without sufficient water pressure support, the connecting pipe 3 and the spray head 4 begin to slowly descend under the elastic force of the second spring 27. During the descent, the connecting block 24 disengages from the push block 23. After the spray head 4 returns to its original position, the connecting block 24 presses down on the push block 23 and moves it downwards, causing the arc-shaped baffle 20 to gradually fall back down, blocking the drain outlet 17 again and preventing the water from continuing to flow out.

[0032] Meanwhile, as the connecting pipe 3 falls, the traction rope 16 slackens, and the blocking ring 12 moves upward under the elastic force of the first spring 26. The overlapping area of ​​the connecting port 13 and the outlet 9 gradually increases, and the drainage volume of the outlet 9 also increases. This further reduces the water pressure in the collecting pipe 2, slowing down the descent speed of the connecting pipe 3. When the connecting pipe 3 returns to the initial position, the connecting port 13 of the blocking ring 12 and the outlet 9 completely overlap again, and the drainage process ends. Then, the process is repeated in the same way.

[0033] The water discharged from the outlet 9 and the drain 17 will re-enter the water collection tank 1 through the water collection cover 7 and the water inlet 8.

[0034] Based on the above, the height of the spray head 4 can be automatically adjusted without external force, thereby achieving the purpose of adjusting the spray range.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
