Description

Technical Field

[0001] This invention relates to the field of agricultural irrigation technology, and more specifically, to a modular water-saving hose for agricultural irrigation. Background Technology

[0002] In agricultural production, irrigation hoses, as the core component for water resource transportation, are widely used in irrigation operations for field crops, cash crops, and facility agriculture.

[0003] Existing spliced ​​hose joints mostly use simple insertion pipe and clamp or threaded connection structure: the former relies on the manual tightening force of the clamp, and gaps are easily formed if the operation is not proper, which can easily lead to leakage under water pressure; the latter has a slightly better sealing effect, but the threaded connection is prone to water leakage problems due to wear or aging of sealant after long-term use. Summary of the Invention

[0004] The purpose of this invention is to provide a spliced ​​water-saving hose for agricultural irrigation to solve the problems mentioned in the background art.

[0005] A spliced ​​water-saving hose for agricultural irrigation includes a hose, one end of which is connected to a first access component, and the other end of which is connected to a first connecting component. A plurality of interface components are connected to the outer surface of the hose, and a plurality of first holes are formed on the upper surface of the hose. Each hole has a second hole formed in the four directions of front, back, left, and right. The first access component includes a first circular connecting block, the outer surface of the first circular connecting block is provided with a first annular groove, and the upper and lower surfaces of the end of the first circular connecting block away from the water hose are connected with L-shaped connecting blocks, and the end of the L-shaped connecting block facing the center of the first circular connecting block is equipped with a first annular connecting block. The first connecting component includes a second circular connecting block. A second annular groove is formed on the surface of the second circular connecting block at the end away from the water hose. First rectangular connecting grooves are formed at both the upper and lower ends of the second annular groove. An arc-shaped fixing groove is formed at one end of each of the first rectangular connecting grooves. A third annular connecting block is connected to the outer side of the second circular connecting block. A movable component is connected to the inner cavity at both ends of the third annular connecting block. A groove is formed on the outer side of the movable component. The L-shaped connecting block fits into the first rectangular connecting block. When the L-shaped connecting block coincides with the first rectangular groove, the first circular connecting block is rotated, which drives the L-shaped connecting block to rotate along the arc-shaped fixing groove until the L-shaped connecting block moves to the other end of the arc-shaped fixing groove. At this time, the two circular connecting blocks are fixed together.

[0006] Preferably, the L-shaped connecting block fits into the first rectangular connecting groove, the arc-shaped fixing groove fits into the L-shaped connecting block, and the first annular connecting block fits into the second annular groove.

[0007] Preferably, the moving component includes a semi-circular fixing block, the edge of the semi-circular fixing block away from the water hose is arc-shaped, and one end of the semi-circular fixing block is connected to a second rectangular connecting block, and the end of the second rectangular connecting block away from the semi-circular fixing block is connected to a first circular guide rod.

[0008] Preferably, a return spring is sleeved on the outer side of the first circular guide rod, and circular holes are opened in the inner cavities of the upper and lower ends of the second rectangular connecting block. A pull rod is connected in the inner cavity of each circular hole. A semi-circular pull block is connected to the end of the pull rod away from the second rectangular connecting block, and one end of the pull rod is connected to the inner surface of the semi-circular pull rod through the end of the third annular connecting block. The pull rod is located on the surface of the circular hole opened near the end of the semi-circular pull rod.

[0009] Preferably, the two semi-circular fixing blocks in the two moving components form a circular fixing block, and the circular fixing block formed by the two semi-circular fixing blocks fits into the first annular groove.

[0010] Preferably, the interface component includes a base component, a fixing component connected to the upper end of the base component, a second access component connected to the upper end of the fixing component, a second connecting component connected to the upper end of the second access component, an L-shaped connecting pipe connected to the upper end of the second connecting component, a valve connected to the inner cavity of the L-shaped connecting pipe, and the components of the first access component and the second access component are the same, as are the components of the first connecting component and the second connecting component.

[0011] Preferably, the base assembly includes a connecting base, the upper surface of which is provided with a fourth annular groove, and the four positions of the fourth annular groove are provided with threaded connection ports, which fit into the second hole.

[0012] Preferably, the fixing component includes a third circular connecting block, a fifth annular connecting block is connected to the lower outer side of the third circular connecting block, and a sixth annular connecting block is connected to the lower surface of the third circular connecting block. The sixth annular connecting block has screws penetrating through it in all four directions (front, back, left, and right), and the four screws are matched with four threaded connection ports.

[0013] Compared with the prior art, the advantages of this invention are: 1. In this invention, a triple collaborative structure consisting of an L-shaped connecting block and an arc-shaped fixing groove, a first annular connecting block and a second annular groove, and a double semi-arc fixing block and a first annular groove is used to achieve all-round sealing and fixing at the joint. After the L-shaped connecting block is embedded in the first rectangular connecting groove, it is locked by rotation through the arc-shaped fixing groove, forming a double mechanical limit in the horizontal and vertical directions, preventing the joint from detaching when the water hose is pulled or impacted by water pressure. The first annular connecting block and the second annular groove fit precisely to form the first sealing barrier, blocking water from leaking from the joint gap. The double semi-arc fixing block automatically embeds into the first annular groove under the action of the return spring, which not only strengthens the structural stability but also forms a second seal, further isolating the seepage path.

[0014] 2. In this invention, splicing only requires three steps: alignment, pushing, and rotation. It does not require special tools such as wrenches and screwdrivers, and a single person can complete the splicing of a single section of water hose, thereby improving the efficiency of splicing water hose. The interface component is detachably connected to the holes on the surface of the water hose via a screw. The installation position and number of L-shaped connecting pipes can be flexibly adjusted according to the farmland layout, such as row spacing or crop distribution. It is suitable for different irrigation modes such as flood irrigation of field, drip irrigation of cash crops, and sprinkler irrigation of facility agriculture, solving the limitation of traditional fixed welded branch interfaces that cannot be adjusted.

[0015] 3. In this invention, when the second connecting component, base component, or fixing component malfunctions, it is not necessary to replace the entire hose. The second connecting component can be separated by pulling the semi-circular pull rod, and the base or fixing component can be disassembled by loosening the screw. The faulty part can be replaced to restore its use, reducing maintenance costs. At the same time, small accessories such as the semi-circular pull rod and screw are connected to the corresponding components through the pull rod or threaded connection, making them less likely to fall off or be lost. Furthermore, the hose can be rolled up and stored as a whole after splicing, reducing storage space and transportation losses, and improving the convenience of equipment management.

[0018] Example: Please refer to Figure 1 A spliced ​​water-saving hose for agricultural irrigation includes a hose 1, one end of the hose 1 is connected to a first access component 2, and the end of the hose 1 away from the first access component 2 is connected to a first connection component 3. A plurality of interface components 4 are connected to the outer surface of the hose 1, and a plurality of first holes are opened on the upper surface of the hose 1. Each hole has a second hole in the front, back, left and right directions. Please see Figure 2 and Figure 3 The first access component 2 includes a first circular connecting block 201. A first annular groove 202 is provided on the outer surface of the first circular connecting block 201. An L-shaped connecting block 203 is connected to the upper and lower surfaces of the end of the first circular connecting block 201 away from the water hose 1. A first annular connecting block 204 is installed at the end of the L-shaped connecting block 203 facing the center of the first circular connecting block 201. Please see Figure 5The first connecting component 3 includes a second circular connecting block 305. A second annular groove 306 is formed on the surface of the second circular connecting block 305 away from the water hose 1. A first rectangular connecting groove 307 is formed at both the upper and lower ends of the second annular groove 306. An arc-shaped fixing groove 319 is formed at one end of each first rectangular connecting groove 307. A third annular connecting block 308 is connected to the outside of the second circular connecting block 305. A moving component 309 is connected to the inner cavity at both ends of the third annular connecting block 308. A groove 310 is formed on the outside of the moving component 309. An L-shaped connecting block 203 fits into the first rectangular connecting groove 307. When the L-shaped connecting block 203 overlaps with the first rectangular connecting groove, the first circular connecting block 201 is rotated, and the L-shaped connecting block 203 is rotated along the arc-shaped fixing groove 319 until the L-shaped connecting block 203 moves to the other end of the arc-shaped fixing groove 319. At this time, the two circular connecting blocks are fixed together.

[0019] Specifically, through the triple collaborative structure of L-shaped connecting block 203 and arc-shaped fixing groove 319, first annular connecting block 204 and second annular groove 306, and double semi-arc fixing block 311 and first annular groove 202, all-round sealing and fixing at the splice is achieved. After L-shaped connecting block 203 is embedded in first rectangular connecting groove 307, it is rotated and locked by arc-shaped fixing groove 319, forming a double mechanical limit in the horizontal and vertical directions, preventing the joint from detaching when the water hose 1 is pulled or impacted by water pressure. The first annular connecting block 204 and second annular groove 306 fit precisely to form the first sealing barrier, blocking water from leaking from the joint gap. Under the action of return spring 315, double semi-arc fixing block 311 automatically embeds into first annular groove 202, which not only strengthens the structural stability but also forms a second seal, further isolating the seepage path.

[0020] The L-shaped connecting block 203 fits into the first rectangular connecting groove 307, the arc-shaped fixing groove 319 fits into the L-shaped connecting block 203, and the first annular connecting block 204 fits into the second annular groove 306.

[0021] Please see Figure 4 The moving component 309 includes a semi-circular fixing block 311. The edge of the semi-circular fixing block 311 away from the water hose 1 is arc-shaped 312. One end of the semi-circular fixing block 311 is connected to a second rectangular connecting block 313. The end of the second rectangular connecting block 313 away from the semi-circular fixing block 311 is connected to a first circular guide rod 314.

[0022] Please see Figure 4A return spring 315 is sleeved on the outer side of the first circular guide rod 314, and circular holes 316 are opened in the inner cavities of the upper and lower ends of the second rectangular connecting block 313. A pull rod 317 is connected in the inner cavity of each circular hole 316. A semi-circular pull rod 318 is connected to the end of the pull rod 317 away from the second rectangular connecting block 313, and one end of the pull rod 317 is connected to the inner surface of the semi-circular pull rod 318 through the end of the third annular connecting block 308. The pull rod 317 is located on the surface of the circular hole 316 opened near the end of the semi-circular pull rod 318.

[0023] The semi-circular fixing blocks 311 in the two moving components 309 will form a circular fixing block, and the circular fixing block formed by the two semi-circular fixing blocks 311 will fit into the first annular groove 202.

[0024] Specifically, splicing only requires three steps: alignment, pushing, and rotation. It does not require special tools such as wrenches and screwdrivers, and a single person can complete the splicing of a single section of water hose, thereby improving the efficiency of splicing water hose 1. The interface component 4 is detachably connected to the holes on the surface of water hose 1 through the screw 413. The installation position and number of L-shaped connecting pipes 405 can be flexibly adjusted according to the farmland layout, such as row spacing or crop distribution. It is suitable for different irrigation modes such as flood irrigation of field, drip irrigation of cash crops, and sprinkler irrigation of facility agriculture, solving the limitation of traditional fixed welded branch interfaces that cannot be adjusted.

[0025] Please see Figure 6 and Figure 7 The interface component 4 includes a base component 401, a fixing component 402 connected to the upper end of the base component 401, a second access component 403 connected to the upper end of the fixing component 402, a second connection component 404 connected to the upper end of the second access component 403, an L-shaped connection pipe 405 connected to the upper end of the second connection component 404, and a valve 406 connected to the inner cavity of the L-shaped connection pipe 405. The components of the first access component 2 are the same as those of the second access component 403, and the components of the first connection component 3 are the same as those of the second connection component 404.

[0026] Please see Figure 8 The base assembly 401 includes a connecting base 407. The upper surface of the connecting base 407 is provided with a fourth annular groove 408. The four positions of the fourth annular groove 408 are provided with threaded connection ports 409, and the four threaded connection ports 409 fit with the second hole. The diameter of the base assembly 401 is smaller than the diameter of the water hose 1.

[0027] Please see Figure 8The fixing component 402 includes a third circular connecting block 410, a fifth annular connecting block 411 connected to the lower outer side of the third circular connecting block 410, and a sixth annular connecting block 412 connected to the lower surface of the third circular connecting block 410. The sixth annular connecting block 412 has screws 413 passing through it in all four directions (front, back, left, right), and the four screws 413 are engaged with four threaded connection ports 409.

[0028] Specifically, when the second connecting component 404 or the base component 401 or the fixing component 402 malfunctions, it is not necessary to replace the entire water hose 1. The second connecting component 404 can be separated by pulling the semi-circular pull rod 318, and the base or fixing component 402 can be disassembled by loosening the screw 413. The faulty part can be replaced to restore its use, reducing maintenance costs. At the same time, small accessories such as the semi-circular pull rod 318 and the screw 413 are connected to the corresponding components through the pull rod 317 or the threaded connection port 409, making them less likely to fall off or be lost. Furthermore, the water hose 1 can be rolled up and stored as a whole after splicing, reducing storage space and transportation losses, and improving the convenience of equipment management.

[0029] Working principle: First, lay the water hose 1 to be spliced ​​horizontally on the ground. Then, align the L-shaped connecting block 203 in the first access component 2 with the first rectangular connecting groove 307 in the first connecting component 3 of the other water hose 1. Then, push the first access component 2 towards the L-shaped connecting block 203. During the movement, the first circular connecting block 201 will move along the inner cavity of the third annular connecting block 308. During the movement, the first circular connecting block 201 will come into contact with the semi-circular fixing block 311 in the two moving components 309, thereby generating a squeezing force on the semi-circular fixing block 311. This will cause the semi-circular fixing block 311 to move along the first circular guide rod 314 towards the groove 310 until the semi-circular fixing block 311 is housed in the inner cavity of the groove 310, releasing the obstruction to the movement of the first circular connecting block 201. At this time, the first circular connecting block 201 continues to move forward until the L-shaped connecting block 203 coincides with the first rectangular connecting groove 307. When the L-shaped connecting block 203 overlaps with the first rectangular connecting groove 307, the first annular connecting block 204 will overlap with the second annular groove 306, and the annular fixing block formed by the two semi-arc fixing blocks 311 will correspond to the first annular groove 202, thereby causing the reset spring 315 to perform a reset operation, and then the annular fixing block will overlap with the first annular groove 202. At this time, the first circular connecting block 201 is rotated, thereby causing the L-shaped connecting block 203 to move along the arc fixing groove 319 until the L-shaped connecting block 203 moves into the inner cavity of the other end of the arc fixing groove 319. At this time, the annular fixing block, the first annular connecting block 204 and the L-shaped connecting block 203 perform a triple fixing operation on the two water hoses 1 and prevent water leakage at the connection between the water hoses 1. Then, the above steps are repeated until the length of the spliced ​​water hose 1 reaches the horizontal length required by the user. After the water hose 1 is assembled, several longitudinal water pipes are connected to the outlet end of the L-shaped connecting pipe 405. Then, the valve 406 is turned and the water valve is opened, allowing water to be transported through the water hose 1 to each L-shaped connecting pipe 405, and then delivered to the water pipes for irrigation of the farmland. If the water flow in a certain water pipe is interrupted or the flow rate is severely reduced, it indicates that there is a problem at the connection of that water pipe. If there is a problem with the second connecting component 404, the water valve is closed, and then the semi-circular pull rod 318 is pulled outward, thereby causing the pull rod 317 to move away from the first circular connecting block 201, and thus causing the second rectangular connecting block 313 and the semi-circular fixing block 311 to move along the first circular guide rod 3. 14. Move away from the first circular connecting block 201 until the semi-circular fixing block 311 is housed in the groove 310, thereby separating the annular fixing block from the first annular groove 202 in the second access component 403. Then rotate the second circular connecting block 305 in the second connecting component 404 so that the first rectangular connecting groove 307 coincides with the L-shaped connecting block 203. Then pull the second connecting component 404 outward, which will separate the second connecting component 404 from the second access component 403. Then replace the second connecting component 404 and perform the same operation according to the connection method of the first connecting component 3 and the first access component 2. Then restore the water pipe filling. If the base assembly 401 or the fixing assembly 402 malfunctions and needs to be replaced, separate the problematic water hose 1 from the adjacent water hose 1, then rotate the screw 413 to separate the screw 413 from the threaded connection port 409, and then pull the fixing assembly 402 outward to separate the fixing assembly 402 from the base assembly 401. At this point, replace the required base assembly 401 or fixing assembly 402. After replacing the base assembly 401 or the fixing assembly 402, align the screw 413 with the threaded connection port 409, then move the fixing assembly 402 downwards until the sixth annular connecting block 412 coincides with the fourth annular groove 408. Then rotate the screw 413 and align the second hole through the surface of the water hose 1 with the threaded connection port 409. Then open the water valve and refill the water hose 1. This completes all operations.
