Description

Technical Field

[0001] This utility model belongs to the technical field of water and fertilizer management devices, specifically relating to an integrated water and fertilizer device for daylily cultivation. Background Technology

[0002] A fertigation system, simply put, is a precision fertilization and irrigation system that integrates irrigation and fertilization. It uses pressure irrigation systems, such as drip irrigation and micro-sprinkler irrigation, to deliver fertilizer dissolved in water directly and evenly to the soil near the crop roots at a relatively low flow rate. The core components of a fertigation system include: a water pump and storage tank, a fertilizer pump and fertilizer tank, a filtration system, a control and measurement system, a water distribution network, and irrigation emitters. When used for daylily cultivation, the fertigation system faces specific requirements due to daylilies' perennial herbaceous nature, extensive root system, and high water and fertilizer requirements. For example, because daylilies have very developed and perennial roots, fine roots can invade and entangle the drip irrigation holes, causing blockages. Therefore, a suitable fertigation system for daylily cultivation needs to minimize or avoid the impact of fine roots on the water distribution network and irrigation emitters. Utility Model Content

[0003] This utility model provides an integrated water and fertilizer device for daylily cultivation to solve at least one of the above-mentioned technical problems.

[0004] The technical solution adopted by this utility model is as follows: a water and fertilizer integrated device for daylily planting, including a drip irrigation pipe, the drip irrigation pipe having multiple spaced-apart connecting pipes, a receiving cavity formed in the middle of the connecting pipe, a filter layer being provided in the receiving cavity; a connecting groove being formed at the end of the connecting pipe, an internal thread being formed on the inner side of the connecting groove, a drip irrigation head being detachably connected to the connecting pipe, an external thread being formed at the end of the drip irrigation head engaging with the internal thread, and a sealing gasket being provided between the drip irrigation head and the connecting groove.

[0005] In a preferred embodiment, the drip head includes a housing and a root-blocking member movably connected within the housing.

[0006] In a preferred embodiment, the housing includes a connector portion that mates with the connecting groove, a sealing portion with a diameter larger than that of the connector portion, and a drip portion with a gradually decreasing diameter; the root-blocking member includes a baffle plate and an extension rod, the extension rod extending through the drip portion to the outside of the housing, the end of the extension rod having a blocking plug, and a return spring sleeved on the extension rod between the extension rod and the drip portion.

[0007] In a preferred embodiment, the baffle plate is hemispherical, and the outer diameter of the baffle plate is larger than the inner diameter of the joint.

[0008] In a preferred embodiment, the inner side of the sealing portion is provided with a plurality of movable tracks extending from one end near the joint portion to the other end, and the outer side of the baffle plate is provided with a movable guide block that cooperates with the movable tracks, so as to limit the movement range of the root-blocking member within the housing by the cooperation of the movable tracks and the movable guide block.

[0009] In a preferred embodiment, a cooperating spring is connected to the bottom of the movable track to assist in the resetting of the root-blocking member through the cooperation of the cooperating spring and the movable guide block.

[0010] In a preferred embodiment, the diameter of the extension rod is the same as the inner diameter of the end of the drip section, and a plurality of water outlet grooves are formed at the end of the extension rod near the blocking plug.

[0011] In a preferred embodiment, the blocking plug is made of rubber or silicone.

[0012] Due to the adoption of the above technical solution, the beneficial effects achieved by this utility model are as follows: 1. As a preferred embodiment of this utility model, by utilizing the combined design of drip irrigation pipe and drip irrigation head, the drip irrigation head can be easily disassembled, cleaned, or replaced after it has penetrated into the daylily root system, avoiding the problem of inability to drip irrigation due to root blockage; by setting a filter layer, the drip irrigation water at the terminal can be filtered to prevent impurities from clogging the drip irrigation head, and the daylily roots can also be prevented from directly penetrating the drip irrigation pipe, thereby protecting the drip irrigation pipe and extending its service life. 2. In a preferred embodiment of this utility model, the cooperation of the outer shell and the root-blocking component allows the water pressure inside the drip irrigation pipe to push the baffle plate towards the dripping section during drip irrigation. At this time, the return spring is compressed, thereby opening the seal of the baffle plate at the head and simultaneously causing the blocking plug to open the seal on the outlet of the dripping section. This allows water from the drip irrigation pipe to flow out from the dripping section through the joint and seal of the outer shell, completing the drip irrigation of daylilies. When irrigation stops, the water pressure in the drip irrigation pipe disappears, and the return spring returns to its original deformation, causing the baffle plate to re-seal the head and simultaneously causing the blocking plug to seal the outlet of the dripping section. After sealing the dripping section, the roots of the daylilies can be effectively prevented from entering the drip head, further eliminating the impact of root blockage.

[0013] 3. As a preferred embodiment of this utility model, by utilizing the cooperating spring, the position recovery of the root blocking component after irrigation is stopped can be further improved, thus completing the sealing of the water outlet at the end of the drip section and improving the reliability of the root blocking component's operation.

[0021] A preferred embodiment, such as Figure 1 and Figure 2As shown, a water and fertilizer integrated device for daylily cultivation is disclosed. The device comprises the following components: a water pump and storage tank, a fertilizer pump and fertilizer tank, a filtration system, a control and measurement system, a water distribution network, and an irrigation device. When cultivating daylilies, a drip irrigation system is typically used. This system includes a drip irrigation pipe 1 with multiple spaced-apart connecting pipes 2. Preferably, the connecting pipes 2 and the drip irrigation pipe 1 are integrally formed. A receiving cavity 21 is formed in the middle of the connecting pipe 2, and a filter layer 22 is provided within the cavity 21. The filter layer 22 can be a filter screen or filter cotton, preferably non-woven filter cotton. A connecting groove 23 is formed at the end of the connecting pipe 2, and an internal thread is formed on the inner side of the connecting groove 23. A drip irrigation head 3 is detachably connected to the connecting pipe 2, and the end of the drip irrigation head 3 has an external thread that engages with the internal thread. A sealing gasket 4 is provided between the drip irrigation head 3 and the connecting groove 23. By utilizing the combined design of drip irrigation pipe 1 and drip irrigation head 3, the drip irrigation head 3 can be easily disassembled, cleaned, or replaced after penetrating the daylily root system, avoiding the problem of not being able to drip properly due to root blockage; by setting the filter layer 22, the drip irrigation water at the terminal can be filtered to prevent impurities from clogging the drip irrigation head 3, and the daylily roots can also be prevented from directly penetrating the drip irrigation pipe 1, thereby protecting the drip irrigation pipe 1 and extending its service life.

[0022] Furthermore, refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The drip head 3 includes a housing 31 and a root-blocking member 32 movably connected within the housing 31.

[0023] Specifically, the outer casing 31 includes a connector 311 that mates with the connecting groove 23, a sealing portion 312 with a diameter larger than that of the connector 311, and a drip portion 313 with a gradually decreasing diameter. The end of the drip portion 313 has a water outlet. The root-blocking member 32 includes a baffle plate 321 and an extension rod 322. The baffle plate 321 covers the connector 311, and the extension rod 322 extends through the water outlet at the end of the drip portion 313 to the outside of the outer casing 31. The end of the extension rod 322 has a blocking plug 323, and a return spring 324 sleeved on the extension rod 322 is located between the extension rod 322 and the drip portion 313. (Refer to...) Figure 3 , Figure 4 , Figure 5 and Figure 6Through the cooperation of the outer casing 31 and the root-blocking component 32, during drip irrigation, the water pressure inside the drip irrigation pipe 1 pushes the baffle plate 321 towards the drip section 313. At this time, the return spring 324 is compressed, thereby opening the seal of the baffle plate 321 at the joint head 311, and simultaneously causing the blocking plug 323 to open the seal on the water outlet at the end of the drip section 313. This allows the water in the drip irrigation pipe 1 to flow out from the drip section 313 through the joint 311 and the sealing part 312 of the outer casing 31, thus completing the drip irrigation of daylilies. (Refer to...) Figure 7 , Figure 8 and Figure 9 When irrigation stops, the water pressure in the drip irrigation pipe 1 disappears. After the return spring 324 recovers its deformation, the baffle plate 321 reconnects to the head 311 to seal it, and at the same time, the blocking plug 323 seals the water outlet at the end of the drip section 313. After sealing the drip section 313, the roots of daylilies can be effectively prevented from invading the drip head 3, further eliminating the impact of root blockage.

[0024] Furthermore, the baffle plate 321 is hemispherical, and its outer diameter is larger than the inner diameter of the connector 311. This facilitates improving the effect of water pressure within the drip irrigation pipe 1 on the baffle plate.

[0025] Furthermore, the inner side of the sealing part 312 is provided with a plurality of movable tracks 314 extending from one end near the joint part 311 to the other end, and the outer side of the baffle plate 321 is provided with movable guide blocks 325 that cooperate with the movable tracks 314, so that the movement range of the root-blocking member 32 within the housing 31 can be limited by the cooperation of the movable tracks 314 and the movable guide blocks 325.

[0026] Furthermore, a cooperating spring 326 is connected to the bottom of the movable track 314 to assist in the reset of the root-blocking member 32 through the cooperation of the cooperating spring 326 and the movable guide block 325. By utilizing the cooperating spring 326, the position recovery of the root-blocking member 32 after irrigation stops can be further improved, thus completing the sealing of the water outlet at the end of the drip section 313.

[0027] Furthermore, the diameter of the extension rod 322 is the same as the inner diameter of the end of the drip section 313, and a plurality of water outlet grooves 327 are formed at the end of the extension rod 322 near the blocking plug 323. The arrangement of the water outlet grooves 327 facilitates the outflow of water after the blocking plug 323 opens to seal the water outlet at the end of the drip section 313. At the same time, the arrangement of multiple water outlet grooves 327 can increase the coverage area of ​​drip irrigation, thereby improving the drip irrigation effect.

[0028] Furthermore, the barrier plug 323 is made of rubber or silicone. The soft material helps to improve the reliability of its sealing and blocking through deformation, and strengthens the prevention of root invasion.
