Description

Technical Field

[0001] The invention relates to the technical field of irrigation, and in particular to a water-saving irrigation device for raising Fritillaria cirrhosa seedlings. Background Art

[0002] As an important medicinal plant, the cultivation process of Fritillaria cirrhosa has attracted much attention. Fritillaria cirrhosa seedlings have strict requirements on the growth environment, among which water conditions are one of the key factors affecting their growth and development as well as the final yield and quality. Appropriate watering is essential for maintaining the physiological balance of Fritillaria cirrhosa seedlings, promoting root growth, and ensuring the normal metabolism of the plants. However, there are currently many problems in the watering of Fritillaria cirrhosa seedlings. On the one hand, due to the lack of precise watering standards, growers often rely on experience to operate, which can easily lead to root rot due to excessive watering, or inhibit plant growth due to insufficient watering. On the other hand, existing watering methods, such as flooding, not only waste water resources, but may also affect the uniform growth of Fritillaria cirrhosa seedlings due to uneven local water distribution. In addition, the water requirements of Fritillaria cirrhosa seedlings at different growth stages vary greatly, and it is difficult to meet their needs with a single watering mode. The roots of Fritillaria cirrhosa seedlings are relatively shallow, and the soil for planting requires relatively loose soil. If too much water is poured, compaction and other conditions will occur, which will kill the seedlings. At the same time, the seedlings will easily be washed away when the water is high. During the planting process, they are often arranged in a parallel row, leaving a certain gap between different rows, and the planting position is slightly higher than the gap.

[0003] In the existing irrigation system, the water flow is not easy to control, and the Fritillaria cirrhosa seedlings require precise humidity control. At the same time, the use of existing technology for irrigation will greatly waste water resources. The Fritillaria cirrhosa seedlings do not require excessive watering. Summary of the invention

Through the above technical scheme, the drip irrigation assembly can control the depth, which is more accurate when in the soil, and can be selected according to the different sizes of Fritillaria cirrhosa seedlings. The drip irrigation head can be retracted after the drip irrigation is completed, and move upward to allow the water outlet to be located in the water collection tank. At this time, water is sprayed to clean the water outlet, and the clear water will flow along the water trough to between the two rows of Fritillaria cirrhosa seedlings, reducing the impact on humidity.

DETAILED DESCRIPTION

[0026] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0027] like Figure 1-Figure 7 As shown, a water-saving irrigation device for raising Fritillaria cirrhosa seedlings is shown. When Fritillaria cirrhosa is planted, it is arranged in rows with gaps between each row. The present invention is arranged at the gap position between two rows, including a connecting bracket 1, on which a plurality of central axes 27 are mounted. The plurality of central axes 27 are arranged along the spacing of the Fritillaria cirrhosa planting rows, that is, the connecting bracket 1 is parallel to the planting direction of Fritillaria cirrhosa, and the central axis 27 is also arranged along this direction. In this embodiment, only one is shown. Atomizing head 16 and atomizing head 2 17 are fixedly mounted on the central axis 27. Atomizing head 16 and atomizing head 2 17 are semicircular, and the opening of atomizing head 16 and atomizing head 2 17 is The mouth is facing the direction of Fritillaria cirrhosa; when water spraying is needed, water enters atomizing head 16 and atomizing head 2 17 through water pipe 1 18 and water pipe 2 19, water pipe 1 18 and water pipe 2 19 are fixedly installed on the connecting bracket 1, connected with the water source, and water is transported to atomizing head 16 and atomizing head 2 17, and atomizing head 1 16 and atomizing head 2 17 can be started respectively according to the humidity conditions at different positions, and operate separately, and atomizing head 1 16 and atomizing head 2 17 on different connecting brackets 1 of different rows can be controlled separately and operated according to the humidity, and a drip irrigation assembly is installed at the lower end of the central shaft 27, and the drip irrigation assembly extends from between two rows of Fritillaria cirrhosa to the vicinity of Fritillaria cirrhosa. Through the above technical scheme, when the Fritillaria cirrhosa has not yet emerged, the atomizer head 2 17 and the atomizer head 1 16 are used for spraying and irrigation. The spraying water is even and covers a large area. After the emergence of the seedlings, drip irrigation is performed through the drip irrigation component to directly send water to the position near the root to avoid water falling on the leaves during spraying and affecting the accuracy of humidity. If spraying on the leaves requires increasing the amount of water to meet the humidity requirements, the use of drip irrigation greatly saves water.

[0028] In this embodiment, a fixed cylinder 21 is fixedly installed on the lower side of the central axis 27, and a movable rod 25 is installed on the inner side. A sliding track 8 is hinged on the lower side of the movable rod 25, and a moving rod 9 is slidably installed on the sliding track 8; a spring 26 is fixedly installed on the movable rod 25, and the upper end of the spring 26 is fixedly connected to the inner side of the fixed cylinder 21. The movable rod 25 slides inside the fixed cylinder 21. In a natural state, the spring 26 drives the movable rod 25 to press upward, and connecting pieces 28 are fixedly installed on both sides of the movable rod 25. A limiting groove 29 is provided on the fixed cylinder 21. The connecting piece 28 slides in the limiting groove 29. When the sliding track 8 is in a horizontal state, the connecting piece 28 is fitted with the upper end of the limiting groove 29, and a long push rod 30 is fixedly installed on the lower end of the central moving block 5. The long push rod 30 moves downward to drive the connecting piece 28 to fit with the lower end of the limiting groove 29; through the above technical solution, the moving rod 9 slides on the sliding track 8 to drive the drip irrigation assembly to move, so as to control the distance from the Fritillaria cirrhosa seedlings. Drip irrigation is performed according to different requirements, and the sliding track 8 fits the lower plate 22 so that the sliding track 8 does not move and interfere with the sliding when the moving rod 9 slides, thereby improving the stability of the equipment.

[0029] In this embodiment, a central screw 4 is rotatably mounted on the fixed cylinder 21, and a central moving block 5 is matched on the central screw 4. A long connecting rod 7 is hinged on the central moving block 5, and the lower end of the long connecting rod 7 is hinged with the moving rod 9; a lower plate 22 is fixedly mounted on the lower plate 22, and a movable shaft 24 is fixedly mounted on the lower plate 22. A movable groove 23 is provided on the sliding track 8, and the movable shaft 24 slides and rotates in the movable groove 23. When the sliding track 8 is in a horizontal state, the upper end of the sliding track 8 fits with the lower end of the lower plate 22. When the movable rod 25 moves downward, the sliding track 8 starts to rotate with the movable shaft 24 as a fulcrum, and the end of the sliding track 8 will tilt up. At the same time, relative sliding and rotation occur between the movable groove 23 and the movable shaft 24, and the movable shaft 24 remains stationary. The movable groove 23 rotates and slides on the movable shaft 24. When the movable rod 25 does not move downward, the central moving block 5 moves downward to drive the long connecting rod 7. The long connecting rod 7 drives the moving rod 9 to slide, which will generate a downward force on the sliding track 8, but the sliding track 8 is close to the lower side of the lower plate 22 and will not be driven. A driving motor 2 is fixedly installed on the connecting bracket 1, and a driving gear 3 is fixedly installed on the rotating shaft of the driving motor 2. A driven gear 20 is fixedly installed on the upper end of the center screw 4, and the driven gear 20 is meshed with the driving gear 3. The rotation of the center screw 4 is controlled by the driving gear 3 and the driven gear 20 to drive the center moving block 5 to move up and down. Through the above technical solution, after the connecting piece 28 is fitted with the lower end of the limiting groove 29, the first end of the moving rod 9 is tilted upward (the end of the moving rod 9 close to the fixed tube 21 is the second end, and the end away from the fixed tube 21 is the first end). The planting position of Fritillaria cirrhosa is higher than the position between the two rows. The upward-tilted moving rod 9 can make the drip irrigation assembly more fit the slope of the soil near the Fritillaria cirrhosa seedlings, and can be inserted into a deeper depth to better control the humidity.

[0030] A drip irrigation assembly is mounted on the moving rod 9. In the present embodiment, the drip irrigation assembly comprises a lifting electric cylinder 10, which is fixedly mounted on the moving rod 9. A sliding seat 12 is fixedly mounted on the lower side of the moving rod 9. The sliding seat 12 is clamped on the lower side of the sliding track 8. A long connecting plate 31 is fixedly mounted on the cylinder arm of the lifting electric cylinder 10. A plurality of drip irrigation heads 33 are mounted on the long connecting plate 31. A water outlet 32 ​​is arranged on the side of the drip irrigation head 33. The water outlet 32 ​​is arranged in the lower half of the drip irrigation head 33. The drip irrigation head 33 is inserted into the soil for drip irrigation. The first end of the movable rod 9 is fixedly provided with a cross bar 11, and the cross bar 11 is slidably connected with the drip irrigation head 33. A water collecting trough 13 is arranged in the cross bar 11. When the drip irrigation head 33 is at the lowest point, the water outlet 32 ​​is located at the lower side of the water collecting trough 13. When the drip irrigation head 33 is at the highest point, the water outlet 32 ​​is located at the upper end of the water collecting trough 13. The drip irrigation head 33 is inserted into the soil for drip irrigation. When it is retracted, a large amount of water is opened to clean the soil in the water outlet 32 ​​and the soil adhered to the drip irrigation head 33. A water flow trough 14 is arranged in the water pipe 19, and the water flow trough 14 is connected with the water collecting trough 13. The water in the water collecting trough 13 flows along the water flow trough 14 to the second end of the movable rod 9.

[0031] The lower end of the drip irrigation head 33 is fixed with a sealing plug 15, which is located at the lower side of the water outlet 32. The sealing plug 15 is inverted cone shape, and the upper end of the sealing plug 15 can block the lower side of the water collection tank 13. At the same time, a humidity test sensor is provided on the sealing plug 15. Through the above technical scheme, the drip irrigation assembly can control the depth, which is more accurate when in the soil. It can be selected according to the different sizes of Fritillaria cirrhosa seedlings. The drip irrigation head 33 can be retracted after the drip irrigation is completed, and move upward to allow the water outlet 32 ​​to be located in the water collection tank 13. At this time, water is sprayed to clean the water outlet 32. Clear water will flow along the water trough 14 between the two rows of Fritillaria cirrhosa seedlings, reducing the impact on the humidity near the Fritillaria cirrhosa seedlings. The humidity test sensor provided can also detect the humidity in the soil layer at any time, making the humidity control more accurate.

[0032] Working principle: The device is installed in the middle of the row spacing of Fritillaria cirrhosa seedlings. The position between two rows of Fritillaria cirrhosa seedlings is lower, so the device is placed at the lowest position and installed using the connecting bracket 1. The two ends of the connecting bracket 1 are fixed on the ground by inserting stakes. Figure 1 As shown, water pipe 18 and water pipe 2 19 are connected to the water source, and when Fritillaria cirrhosae Bulbs has not germinated, a sprinkler irrigation method is used, such as Figure 4 As shown, the water in the water pipe 18 and the water pipe 2 19 is connected to the atomizing head 16 and the atomizing head 2 17, and water is sprayed when needed, the water is atomized, and controlled according to the required position; when the Fritillaria cirrhosa seedlings grow out, it is not suitable for spraying, and drip irrigation is adopted. The water pipe is pre-buried underground between the two rows of Fritillaria cirrhosa seedlings, and the water pipe is connected to the drip irrigation assembly, such as Figure 5As shown, the driving motor 2 is started to drive the driving gear 3 and the driven gear 20 to rotate, and the driven gear 20 drives the central screw 4 to rotate on the fixed cylinder 21, and the fixed cylinder 21 is fixedly connected to the connecting bracket 1 through the central shaft 27 (as shown in FIG. Figure 4 ),like Figure 1 As shown, the central moving block 5 starts to move downward. During the downward movement of the central moving block 5, the moving rod 9 is driven to slide on the sliding track 8 through the long connecting rod 7, and at the same time, the two drip irrigation assemblies are driven to move to both sides closer to the Fritillaria cirrhosa seedlings, stop at a suitable position, and start the lifting electric cylinder 10. Figure 7 As shown, the lifting electric cylinder 10 drives the long connecting plate 31 to move downward, drives the drip irrigation head 33 to be inserted into the soil, so that the water outlet 32 ​​is inserted into the soil by about 3 cm, and drip irrigation begins. At the same time, the humidity sensor on the sealing plug 15 monitors the humidity. When the humidity is appropriate, drip irrigation is stopped, and the lifting electric cylinder 10 retracts, driving the long connecting plate 31 and the drip irrigation head 33 to move upward until the upper end of the sealing plug 15 supports the lower end of the cross bar 11 and the opening position where the drip irrigation head 33 and the cross bar 11 are connected. At this time, the water volume is increased to clean the soil blocked in the water outlet 32. The cleaned water flows into the water flow trough 14 in the water collection trough 13, and then flows to the second end of the moving rod 9 and is sprinkled between the two rows of Fritillaria cirrhosa seedlings.

[0033] When drip irrigation is required at a position very close to the Fritillaria cirrhosa seedlings, the central moving block 5 is moved to the lowest end. Figure 6 As shown, the central moving block 5 drives the long push rod 30 to push the connecting piece 28 to the lowest end, and the connecting piece 28 drives the movable rod 25 to stretch the spring 26. The movable rod 25 moves downward to drive the end of the sliding track 8 to tilt upward, forming a shape in which the middle is low and the two ends of the drip irrigation assembly tilt upward. The Fritillaria cirrhosa seedlings are planted in this way, arranged at the high places of rows, while the present invention is arranged at the low place between two rows. This shape is just adapted to the ridge, allowing the drip irrigation head 33 to be inserted into a deeper position and closer to the Fritillaria cirrhosa seedlings.

[0034] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
