Micro-sprinkler emitters for integrated water and fertilizer drip irrigation of fruit seedlings

Abstract

This application relates to the field of drip irrigation technology for fruit seedlings, and discloses a micro-sprinkler for integrated water and fertilizer drip irrigation of fruit seedlings, including a plug and a dripper body disposed on one side of the plug. A snap-fit ​​connector is fixedly connected to the upper end of the plug. The plug is in the shape of an inverted cone. A snap-fit ​​groove is opened on the outer wall of the middle part of the snap-fit ​​connector. A hollow ring is bonded to the inner wall of the snap-fit ​​connector located inside the snap-fit ​​groove. The hollow ring is made of rubber. The technical solution of this application allows the plug to be easily inserted into the opening of the PVC hose. The outer wall of the opening of the PVC hose will snap into the snap-fit ​​groove of the snap-fit ​​connector. Then, under tension, the outer wall of the PVC hose retracts and presses against the outer wall of the hollow ring, thereby playing a sealing role and ensuring the pressure inside the dripper body. When the weather is cold, when the tension of the outer wall of the PVC hose retracts, the hollow ring resets under the pressure inside the hollow ring, and the outer wall of the hollow ring continues to adhere to the outer wall of the PVC hose, thereby effectively preventing water leakage and enhancing the stability of the internal pressure of the dripper body.

Description

Technical Field

[0001] This application relates to the field of nursing ice pack technology, specifically a micro-sprinkler dripper for integrated water and fertilizer drip irrigation of fruit seedlings. Background Technology

[0002] In the integrated drip irrigation system for fruit seedlings, the micro-sprinkler is a key component, and its selection directly affects irrigation efficiency, water and fertilizer utilization, and crop growth.

[0003] Currently, PVC hoses are generally used for water supply in drip irrigation systems for fruit seedlings. A portable dripper is available on the market, which has a hole in the outer wall of the PVC hose. Because the PVC hose is elastic, it is easy to insert the portable dripper into the inner wall of the PVC hose, thereby achieving the effect of micro-spraying water to the fruit seedlings. However, the outer wall of the PVC hose opening is elastic. In cold weather, the outer wall of the opening may shrink back, resulting in a gap between the dripper insertion position and the outer wall of the opening, causing water leakage and affecting the internal pressure of the dripper. Utility Model Content

[0004] The purpose of this application is to provide a micro-sprinkler dripper for integrated water and fertilizer drip irrigation of fruit seedlings. This solves the problem mentioned in the background art that fruit seedling drip irrigation systems generally use PVC hoses for water supply. There is a portable dripper on the market that can be installed with a hole in the outer wall of the PVC hose. Because the PVC hose is elastic, it is easy to insert the portable dripper into the inner wall of the PVC hose, thereby achieving the function of micro-sprinkling water to the fruit seedlings. However, the outer wall of the PVC hose opening is elastic. In cold weather, the outer wall of the opening will shrink back, which will cause gaps between the insertion position of the dripper and the outer wall of the opening, resulting in water leakage and affecting the internal pressure of the dripper.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This application provides a micro-sprinkler for integrated water and fertilizer drip irrigation of fruit seedlings, including a plug and a dripper body disposed on one side of the plug. The upper end of the plug is fixedly connected to a snap connector. The plug is in the shape of an inverted cone. The outer wall of the middle part of the snap connector has a snap groove. The inner wall of the snap connector located inside the snap groove has a hollow ring bonded to it. The hollow ring is made of rubber.

[0007] By adopting the above technical solution, the plug can be easily inserted into the PVC opening, and the outer wall of the PVC hose opening will be engaged in the engagement groove of the connector. Then, under tension, the outer wall of the PVC hose retracts and presses against the outer wall of the hollow ring, thereby achieving a sealing effect and ensuring the pressure inside the dripper body. When the weather is cold, when the tension of the outer wall of the PVC hose retracts, the hollow ring resets under the pressure inside, allowing the outer wall of the hollow ring to continue to adhere to the outer wall of the PVC hose, thereby effectively preventing water leakage and enhancing the stability of the pressure inside the dripper body.

[0008] Optionally, the drip head body includes a threaded head, the lower end of which is threaded with a positioning head, and the outer wall of the positioning head is threaded with a positioning ring.

[0009] By adopting the above technical solution, the positioning head can be used to install the threaded head, and the positioning head can be installed in the inner wall of the positioning ring.

[0010] Optionally, the lower end of the positioning ring is fixedly connected to a plug rod, and the lower side of the plug rod is set at an angle.

[0011] By adopting the above technical solution, the positioning ring can fix the insertion rod, which can be inserted into the seedling field to adjust the dripper head's drip irrigation position.

[0012] Optionally, a nut is threaded onto the outer wall of the threaded head, and the outer wall of the nut has multiple sets of L-shaped drip holes.

[0013] By adopting the above technical solution, the threaded head can be used to install the nut, and the drip hole on the nut can be used for drip irrigation.

[0014] Optionally, the inner wall of the threaded head is provided with a tapered hole, which communicates with multiple sets of drip holes.

[0015] By adopting the above technical solution, the conical hole is connected to the drip hole, which facilitates the delivery of water to the drip hole. Furthermore, the conical hole is designed in a conical shape, which can further enhance the pressure of the water flow.

[0016] Optionally, a connecting rod is fixedly installed at the lower end of the nut located between the multiple sets of drip holes, and a plug is fixedly installed at the lower end of the connecting rod.

[0017] By adopting the above technical solution, when the height is adjusted by rotating the nut, its thread can drive the connecting rod to move vertically, and the connecting rod can drive the plug to move vertically, thereby adjusting the water pressure of the tapered hole and also closing it.

[0018] Optionally, a connecting pipe is fixedly installed at the lower end of the positioning head, and the connecting pipe is fixedly installed at the upper end of the clamp connector.

[0019] By adopting the above technical solution, the connecting pipe can connect the clamp connector and the drip head body.

[0020] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0021] The technical solution of this application allows the plug to be easily inserted into the PVC opening, and the outer wall of the PVC hose opening will be engaged in the engagement groove of the connector. Then, under tension, the outer wall of the PVC hose retracts and presses against the outer wall of the hollow ring, thereby achieving a sealing effect and ensuring the pressure inside the dripper body. When the weather is cold, when the tension of the outer wall of the PVC hose retracts, the hollow ring returns to its original position under the pressure inside, allowing the outer wall of the hollow ring to continue to adhere to the outer wall of the PVC hose, thereby effectively preventing water leakage and enhancing the stability of the internal pressure of the dripper body.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-4 This application provides a technical solution: a micro-sprinkler for integrated water and fertilizer drip irrigation of fruit seedlings, including a plug 1 and a drip body 5 disposed on one side of the plug 1. The upper end of the plug 1 is fixedly connected to a clamping connector 2. The plug 1 is in the shape of an inverted cone. The outer wall of the middle part of the clamping connector 2 is provided with a clamping groove 3. The inner wall of the clamping connector 2 located inside the clamping groove 3 is bonded with a hollow ring 4, which is made of rubber.

[0030] In the technical solution of this application, the plug 1 can be easily inserted into the PVC opening, and the outer wall of the PVC hose opening will be engaged in the engagement groove 3 at the connector 2. Then, under tension, the outer wall of the PVC hose retracts and presses against the outer wall of the hollow ring 4, thereby playing a sealing role and ensuring the pressure inside the dripper body 5. When the weather is cold, when the tension of the outer wall of the PVC hose retracts, the hollow ring 4 resets under the pressure inside the hollow, and the outer wall of the hollow ring 4 continues to adhere to the outer wall of the PVC hose, thereby effectively preventing water leakage and enhancing the stability of the pressure inside the dripper body 5.

[0031] In the technical solution of this application, such as Figure 3 and Figure 4 As shown, the dripper body 5 includes a threaded head 501. A positioning head 6 is threadedly installed at the lower end of the threaded head 501. A positioning ring 7 is threadedly installed on the outer wall of the positioning head 6. The positioning head 6 can be used to install the threaded head 501, and it can be installed in the inner wall of the positioning ring 7. A nut 503 is threadedly installed on the outer wall of the threaded head 501. The outer wall of the nut 503 has multiple sets of L-shaped drip holes 504. The threaded head 501 can be used to install the nut 503, and the drip holes 504 on the nut 503 can be used for drip irrigation. A tapered hole 502 is provided on the inner wall of the threaded head 501. The conical orifice 502 is connected to multiple sets of drip holes 504. The connection between the conical orifice 502 and the drip holes 504 facilitates the delivery of water to the drip holes 504. The conical shape of the conical orifice 502 further enhances the pressure of the water flow. A connecting rod 505 is fixedly installed at the lower end of the nut 503 located between the multiple sets of drip holes 504. A plug 506 is fixedly installed at the lower end of the connecting rod 505. When the height is adjusted by rotating the nut 503, its thread can drive the connecting rod 505 to move vertically. The connecting rod 505 drives the plug 506 to move vertically, thereby regulating the water pressure of the conical orifice 502 and also closing it.

[0032] In the technical solution of this application, such as Figure 3 As shown, a connecting pipe 9 is fixedly installed at the lower end of the positioning head 6. The connecting pipe 9 is fixedly installed at the upper end of the clamp connector 2. The connecting pipe 9 can connect the clamp connector 2 and the drip head body 5.

[0033] In the technical solution of this application, such as Figure 3 As shown, the lower end of the positioning ring 7 is fixedly connected to the insertion rod 8. The lower side of the insertion rod 8 is set at an angle. The positioning ring 7 can fix the insertion rod 8, and the insertion rod 8 can be inserted into the seedling bed to adjust the drip irrigation position of the dripper body 5.

[0034] In use, the stopper 1 can be easily inserted into the PVC opening, and the outer wall of the PVC hose opening will engage with the locking groove 3 at the stopper 2. Then, under tension, the outer wall of the PVC hose retracts and presses against the outer wall of the hollow ring 4, thus achieving a seal and ensuring the pressure inside the dripper body 5. In cold weather, when the tension of the PVC hose outer wall retracts, the hollow ring 4 returns to its original position under the pressure inside, continuing to adhere its outer wall to the outer wall of the PVC hose, effectively preventing water leakage and enhancing the stability of the pressure inside the dripper body 5. The connecting tube 9 can connect the stopper 2 and the dripper... The main body 5 serves as a connector, facilitating water supply to the dripper body 5. The positioning head 6 in the dripper body 5 can be threaded into the positioning ring 7, and the insertion rod 8 can position the positioning ring 7, facilitating the replacement of the dripper body 5 with a different drip position. When the nut 503 rotates and adjusts the thread on the outer wall of the threaded head 501, the nut 503 can drive the connecting rod 505 to move vertically. The connecting rod 505 can drive the plug 506 to move vertically, facilitating further regulation of water pressure inside the conical hole 502 and also closing the conical hole 502.
