All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
An embodiment of the water and fertilizer integrated intelligent water and fertilizer irrigation device for actinidia arguta of the invention, as shown in fig. 1 to 8, comprises a water pipe 200, a support rod 400 and a drip irrigation mechanism 500.
The number of the support rods 400 and the drip irrigation mechanism 500 is plural, and the support rods and the drip irrigation mechanism are alternately distributed in sequence, and the water pipe 200 is erected above the ground at a preset height, and the preset height can be 30CM in general.
The water pipe 200 is sequentially communicated with the drip irrigation mechanisms 500 and fixedly connected with the support rods 400, and the connection position of two adjacent support rods 400 and the water pipe 200 is higher than the communication position of the drip irrigation mechanism 500 between the two support rods 400 and the water pipe 200, so that residual water at the position between the two support rods 400 in the water pipe 200 can be collected to the drip irrigation mechanism 500 when water supply in the water pipe 200 is stopped, and water in the water pipe 200 is drained.
The drip irrigation mechanism 500 includes an outer tube 510, an inner tube 520, a first valve assembly 530, and a second valve assembly 540, the inner tube 520 being positioned within the outer tube 510, the outer tube 510 being in communication with the water conduit 200; and the outer tube 510 is internally provided with a first water inlet 501, the side wall of the inner tube 520 is provided with a second water inlet 502, the second water inlet 502 is positioned below the first water inlet 501, and water flows from the water pipe 200 into the outer tube 510, sequentially flows through the first water inlet 501 and the second water inlet 502 and then is discharged from the lower end of the inner tube 520. The first valve assembly 530 is used for blocking the first water inlet 501, the second valve assembly 540 is used for blocking the second water inlet 502, the first valve assembly 530 enables the first water inlet 501 to be opened when the water flow pressure in the outer pipe 510 is increased to a first preset value, and enables the first water inlet 501 to be closed when the water flow pressure at the first water inlet 501 is reduced to a fourth preset value; the second valve assembly 540 opens the second water inlet 502 when the pressure of the water flow in the outer pipe 510 increases to a second preset value, closes the second water inlet 502 when the pressure of the water flow at the second water inlet 502 decreases to a third preset value, and accelerates the water flow in the inner pipe 520 to be discharged when the second water inlet 502 is closed; the third preset value and the fourth preset value are smaller than the first preset value, the third preset value is larger than the fourth preset value, and the first preset value is smaller than the second preset value.
The first preset value can be set to be a water pressure value in the water pipe 200 after the water pipe 200 is filled with water flow, the first valve component 530 enables the first water inlet 501 to be opened when the water flow pressure in the water pipe 200 is increased to the first preset value, the second valve component 540 enables the second water inlet 502 to be opened when the water flow pressure in the outer pipe 510 is increased to the second preset value, and therefore each drip irrigation mechanism 500 can be opened simultaneously, and irrigation at different positions is more uniform. The fourth preset value may be set to 0, i.e., the first valve assembly 530 closes the first water inlet 501 when no water passes through the first water inlet 501. Because water flows through the first water inlet 501 and the second water inlet 502 in sequence, the water flow pressure at the first water inlet 501 is reduced firstly, the third preset value is larger than the fourth preset value, the second water inlet 502 is closed after the first water inlet 501 is closed, the first water inlet 501 is closed firstly, the backflow of residual water from the first water inlet 501 when the second valve assembly 540 accelerates the water flow in the inner pipe 520 to be discharged can be prevented, and the water at different positions is irrigated more uniformly by arranging the first water inlet 501, the second water inlet 502, the first valve assembly 530 and the second valve assembly 540, the water residues in the drip irrigation mechanism 500 and the water pipe 200 are reduced simultaneously, the irrigation effect is improved, and the service life of the device is prolonged.
In this embodiment, the second valve assembly 540 is disposed in the outer tube 510 and includes a sealing ring 541, a sealing tube 542, a second elastic member 543, a locking block 544 and a third elastic member 545, wherein the sealing ring 541 and the sealing tube 542 are both sleeved outside the inner tube 520 in a vertically sliding manner, and the sealing ring 541 is located above the sealing tube 542 and connected to the sealing tube 542 through the third elastic member 545, and the third elastic member 545 urges the sealing ring 541 and the sealing tube 542 to approach each other. The sealing cylinder 542 is connected with the outer tube 510 through a second elastic piece 543, and the second elastic piece 543 drives the sealing cylinder 542 and the sealing ring 541 to move upwards, so as to seal the second water inlet 502 on the side wall of the inner tube 520. Specifically, the lower end of the outer tube 510 is plugged, and the lower end of the inner tube 520 extends out of the outer tube 510 after passing through the lower end surface of the outer tube 510. The upper end of the closed tube 542 is provided with an annular protrusion attached to the inner wall of the outer tube 510, the second elastic member 543 is sleeved outside the closed tube 542, and the upper end and the lower end of the second elastic member are respectively abutted against or connected with the annular protrusion and the lower end face of the outer tube 510. The upper end of the closed cylinder 542 is provided with a vertically extending mounting groove, and the lower side of the sealing ring 541 is provided with a mounting column 546 which is in sliding fit with the mounting groove along the vertical direction; the locking block 544 is horizontally and slidably arranged in the mounting groove, and the locking block 544 can pass through the side wall of the mounting groove to be abutted with the inner wall of the outer tube 510; specifically, the mounting groove is disposed on the upper end surface of the annular protrusion, and the third elastic member 545 is disposed in the mounting groove and connects the annular protrusion and the sealing ring 541 respectively; the mounting groove is provided with a through hole penetrating through the side close to the inner wall of the outer tube 510, and the locking block 544 is slidably mounted in the through hole. The locking block 544 is positioned at the lower side of the mounting column 546 and is in inclined fit with the mounting column 546, and when the mounting column 546 moves downwards relative to the closed cylinder 542, the locking block 544 is pushed to move away from the inner tube 520; specifically, the sides of the locking block 544 and the mounting post 546 that are adjacent to each other are inclined surfaces, and the two inclined surfaces are slidably connected and are not separated all the time. The side wall of the outer tube 510 is provided with an avoidance groove 511, the avoidance groove 511 is positioned below the second water inlet 502, and when the closed cylinder 542 moves to enable the locking block 544 to extend out of the through hole to be matched with the avoidance groove 511, the locking block 544 prevents the closed cylinder 542 from moving up and down in the outer tube 510; wherein the stiffness coefficient of the third elastic member 545 is smaller than that of the second elastic member 543.
In the initial state, the sealing cylinder 542 pushes the sealing ring 541 to above the second water inlet 502 under the action of the second elastic member 543, and the inner wall of the sealing cylinder 542 seals the second water inlet 502. The water inflow in the outer tube 510 makes the sealing ring 541 and the closing cylinder 542 move downwards under the action of water flow, and in the process of moving downwards, the sealing ring 541 and the closing cylinder 542 are close to each other under the action of water flow, the locking block 544 is extruded to move away from the inner tube 520 to extend out of the through hole and abut against the inner wall of the outer tube 510, after the water flow pressure is increased to a second preset value, the sealing ring 541 and the closing cylinder 542 move to the lower part of the second water inlet 502, the locking block 544 moves to the position of avoiding the groove 511, and the locking block 544 cooperates with the avoiding groove 511 to prevent the closing cylinder 542 from moving upwards or downwards. Because the stiffness coefficient of the third elastic member 545 is smaller, the sealing ring 541 keeps the extrusion locking block 544 to be matched with the avoidance groove 511 under the action of water flow until the water flow pressure above the sealing ring 541 is reduced to a third preset value, and the sealing ring 541 drives the mounting column 546 to move upwards under the action of the third elastic member 545, so that the locking block 544 is disengaged from the avoidance groove 511, and the sealing cylinder 542 and the sealing ring 541 are allowed to move upwards to be reset under the action of the second elastic member 543; at this time, the water in the outer tube 510 is small, the water pressure is small, the sealing cylinder 542 and the sealing ring 541 can move upward rapidly under the action of the second elastic member 543, and the residual water in the outer tube 510 is accelerated to be discharged.

The inner tube 520 is fixed in the outer tube 510, and the upper end of the inner tube 520 is positioned in the lower tube section of the outer tube 510; the first valve assembly 530 includes a block 531 and a first elastic member 532, the block 531 is slidably mounted on the lower pipe section of the outer pipe 510 up and down, a water flow channel 533 is reserved between the block 531 and the lower pipe section of the outer pipe 510, and when the first water inlet 501 is opened, water flows into the lower pipe section of the outer pipe 510 through the water flow channel 533. The first elastic member 532 is disposed between the stop 531 and the inner pipe 520, and is used for urging the stop 531 to abut against the upper pipe section so as to block the first water inlet 501, specifically, a ring table is disposed on an inner wall surface of an upper end portion of the inner pipe 520, and two ends of the first elastic member 532 are respectively connected with the ring table and the stop 531. Wherein the stiffness coefficient of the first elastic member 532 is smaller than that of the second elastic member 543. In the initial state, the sealing ring 541 abuts against the stop 531 under the action of the second elastic member 543, so as to prevent the stop 531 from moving downward when the water pressure in the outer tube 510 does not reach the first preset value. The water in the water pipe 200 enters the upper pipe section of the outer pipe 510, so that the water flow pressure in the outer pipe 510 is increased until the water flow pressure reaches a first preset value, the pushing stop 531, the sealing ring 541 and the sealing cylinder 542 move downwards, the first water inlet 501 is opened, the water flow flows downwards through the water flow passage 533, and the pushing of the sealing ring 541 and the sealing cylinder 542 is continued.

When the sealing cylinder 542 moves upwards to a preset position, the T-shaped block is abutted with the bottom of the vertical chute, and the transmission rod 561 is driven to synchronously move upwards when the sealing cylinder 542 continues to move upwards. By arranging the vertical sliding groove, the moving stroke of the transmission rod 561 is reduced, and when the sealing cylinder 542 moves upwards to a preset position, the residual water in the inner pipe 520 is basically drained, and at the moment, the sealing cone 562 is driven to move, so that the residual water in the inner pipe 520 is not blocked.
In this embodiment, an integrated intelligent water and fertilizer irrigation device for actinidia arguta further includes an automatic exhaust valve 300, where the automatic exhaust valve 300 is disposed at one end of the water pipe 200 far away from the water inlet side, and is used for exhausting gas in the water pipe 200 when the water pipe 200 is in water.

And a plurality of check valves 600 are respectively positioned on the water pipe 200 near the position of the support rod 400.
The check valve 600 and the automatic exhaust valve 300 cooperate to make the air pressure in the water pipe 200 and the upper pipe section of the outer pipe 510 be level with the external atmospheric pressure, and when the water pipe 200 stops supplying water and the water level in the outer pipe 510 drops to the lower pipe section of the outer pipe 510, a negative pressure is formed in the lower pipe section of the outer pipe 510, and the blocking block 531 is reset under the action of the first elastic member 532, so that the water in the outer pipe 510 can continue to flow downwards. When the sealing ring 541 and the closing cylinder 542 move upward to press the space inside the outer tube 510, the air pressure inside the outer tube 510 increases, allowing the stopper 531 to return under the action of the first elastic member 532, blocking the water inside the outer tube 510 from flowing backward upward.
In the present embodiment, a sealing joint 512 is provided at a position where the upper pipe section of the outer pipe 510 communicates with the water pipe 200; the upper tube section of the outer tube 510 is connected to the water pipe 200 by a sealing joint 512.

When irrigation is carried out, irrigation water (generally water mixed with fertilizer) is input into the water pipe 200, the irrigation water in the water pipe 200 sequentially flows to the upper pipe section of the outer pipe 510 of the drip irrigation mechanism 500, the water flow pressure in the upper pipe section of the outer pipe 510 is increased to a first preset value, the water flow pushing stop 531, the sealing ring 541 and the sealing cylinder 542 move downwards, the first water inlet 501 is opened, the water flow flows downwards through the water flow channel 533, the sealing ring 541 and the sealing cylinder 542 continue to move downwards along with the increase of the water flow pressure until the water flow pressure is increased to a second preset value, the sealing ring 541 and the sealing cylinder 542 move to the lower part of the second water inlet 502, the locking block 544 moves to the position of the avoidance groove 511, and the locking block 544 cooperates with the avoidance groove 511 to prevent the sealing cylinder 542 from moving upwards or downwards. At this time, irrigation water enters from the first water inlet 501, enters the lower pipe section of the outer pipe 510 through the water flow path 533, enters the inner pipe 520 through the second water inlet 502, and then is discharged from the pressure compensating drip 550. After irrigation is completed, the water delivery pipe 200 stops supplying water, residual irrigation water in the water delivery pipe 200 converges towards the drip irrigation mechanism 500 between the two support rods 400, when the water flow pressure value in the upper pipe section of the outer pipe 510 is reduced to a fourth preset value (generally 0), the stop block 531 has a trend of moving upwards under the action of the first elastic piece 532, but as the water level in the outer pipe 510 drops to the lower pipe section of the outer pipe 510, negative pressure is formed in the lower pipe section of the outer pipe 510, and the stop block 531 is blocked from resetting under the action of the first elastic piece 532, so that water in the outer pipe 510 can continuously flow downwards. When the water flow pressure above the sealing ring 541 is reduced to a third preset value, the sealing ring 541 drives the mounting column 546 to move upwards under the action of the third elastic piece 545, so that the locking block 544 is disengaged from the avoiding groove 511, the sealing cylinder 542 and the sealing ring 541 are allowed to move upwards quickly and reset under the action of the second elastic piece 543, and water in the outer pipe 510 is caused to enter the inner pipe 520 from the upper end of the inner pipe 520 or the second water inlet 502 and then is discharged; and during the moving process, the air pressure in the outer tube 510 is increased, so that the stop 531 is allowed to reset under the action of the first elastic member 532, and the water in the outer tube 510 is blocked from flowing backwards upwards. After the sealing cylinder 542 moves upwards to a preset position, the transmission rod 561 and the sealing cone 562 are driven to synchronously move upwards, so that the sealing cone 562 seals the pressure compensation drip head 550, and the pressure compensation drip head 550 is prevented from being blocked by foreign objects in a non-working state.
