Description

Technical Field

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

[0002] Agricultural and garden irrigation devices are equipment used to provide water to crops, flowers, turf, etc., with the aim of achieving efficient and precise irrigation, saving water resources, and improving the growth quality of plants.

[0003] Chinese patent application CN202311273876.9 discloses an agricultural and garden irrigation device, including an outer pipe, a nozzle at the top of the outer pipe, an inner pipe fixedly installed at the bottom of the nozzle, a piston plate fixedly installed on the outer wall at the bottom of the inner pipe, a float at the bottom of the inner pipe, a connecting rod fixedly installed on the top of the float, the connecting rod being movably connected to the piston plate, a lower magnetic ring on the outer wall of the inner pipe, an upper magnetic ring above the lower magnetic ring, and a coil on the outer ring of the upper magnetic ring.

[0004] The above technical solution uses the buoyancy of the float to automatically raise the device. After raising, the magnetic force of the lower and upper magnetic rings supports the main weight of the lifting sprinkler head, reducing the loss of buoyancy due to irrigation water pressure. The floating of the sprinkler head generates an induced current in the coil, which is displayed on the indicator light on the top of the sprinkler head, achieving the effect of fault indication. However, some traditional lifting sprinklers have multiple water outlets on their surface. Water is sprayed out through these outlets to spray the turf. After the lifting sprinkler head is raised and lowered, it is fixed. Because there are gaps between the multiple water outlets, when water is sprayed out of the outlets, the garden areas reflected outward between the gaps will not be irrigated or the irrigation amount will be very small, affecting the irrigation quality of the turf. Moreover, after the lifting sprinkler head is reset, because there is no protective plate on the top of the lifting sprinkler head, grass clippings, dead leaves and other solids will fall on the lifting sprinkler head, which will cause blockage over time and make it difficult for the lifting sprinkler head to be used normally next time. Summary of the Invention

[0005] The purpose of this invention is to provide a water-saving irrigation device for agricultural and horticultural use, in order to solve the problems mentioned in the background art above: To achieve the above objectives, the present invention provides the following technical solution: An agricultural and horticultural irrigation water-saving device includes a watering apparatus installed on the ground. Multiple nozzle pipes connected to the top surface of the watering apparatus are fixedly installed. The nozzle pipes have internal grooves, and matching sliding columns are slidably connected inside the grooves. A rotating groove is formed on the top surface of the sliding column, and a matching rotating ring is rotatably connected inside the groove. The groove and ring fit together and seal. A sprayer is fixedly installed on the top surface of the rotating ring, and the surface of the sprayer has several watering holes. The sliding column has internal grooves... The device includes a water inlet channel with a protrusion fixedly installed on its inner wall. A fixing ring is fixedly installed inside the water inlet channel, and a matching slide rod is slidably connected inside the fixing ring. A lifting rod is fixedly installed on the top surface of the slide rod, and a sealing head that seals with the protrusion is fixedly installed on the top surface of the lifting rod. A base plate is fixedly installed on the bottom surface of the slide rod, and a through-hole circular groove is formed on the surface of the base plate. A suspended ball that seals with the circular groove is fixedly installed on the bottom surface of the slide rod, and a first spring for resetting its movement is sleeved on the surface of the slide rod.

[0006] Preferably, two connecting rods are provided between the fixing ring and the inner wall of the water inlet channel. The fixing ring is fixedly connected to the inner wall of the water inlet channel through the connecting rods. One end of the first spring is fixedly connected to the surface of the suspended ball, and the other end of the first spring is fixedly connected to the bottom surface of the fixing ring.

[0007] Preferably, two mounting plates are fixedly installed on the surface of the nozzle pipe. Each of the two mounting plates has a slot communicating with a sliding groove. Each of the two slots has a matching wedge block slidably connected inside it. Each of the two wedge blocks is fixedly connected to the surface of the sliding column. A second spring is elastically connected between the wedge block and the slot. One end of the second spring is fixedly connected to the inner wall of the slot, and the other end of the second spring is fixedly connected to the wedge block.

[0008] Preferably, the inner walls of both slots are slidably connected with through guide rods, one end of each guide rod is fixedly mounted with a connecting frame, one end of each connecting frame is fixedly mounted with a closing plate, and the surface of each guide rod is sleeved with a third spring for resetting, one end of the third spring is fixedly connected to the surface of the mounting plate, and the other end of the third spring is fixedly connected to the connecting frame.

[0009] Preferably, the wedge block includes a ramp surface and a plane, the ramp surface and the plane are connected, and the ramp surface contacts one end of the guide rod.

[0010] Preferably, a plurality of blades are fixedly installed on the surface of the rotating ring, and airflow nozzles for blowing the blades are fixedly installed on the surfaces of both of the sealing plates, with the airflow nozzles and the blades being inclined to correspond to each other.

[0011] Preferably, the airflow nozzle includes an air outlet and an air inlet pipe, the air outlet is correspondingly arranged with the deflector, and after the sprayer exits the nozzle pipe, the deflector and the air outlet are positioned correspondingly.

[0012] Preferably, the surface of the watering device has the same number of openings as the nozzle pipes. After the suspended ball separates from the circular groove, the water inlet channel is connected to the watering device through the openings. A water inlet pipe is fixedly installed on one end of the watering device.

[0013] Preferably, a mounting bracket is fixedly installed on the surface of the watering device, and an air pump is fixedly installed on the surface of the mounting bracket. The air outlet of the air pump is sealed and connected to the air inlet pipe through a multi-port pipe.

[0014] Preferably, the bottom surface of the watering device is provided with two supports for supporting it, the two supports are in contact with the bottom surface, and the supports are fixedly connected to the bottom surface of the watering device.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1) This water-saving irrigation equipment for agricultural and horticultural use works by pumping water into the inlet pipe, which then enters the irrigation device. The water acts on the bottom surface of the base plate through the openings, causing the base plate to move upwards under water pressure, which in turn moves the sliding column. This causes two wedge-shaped blocks to move upwards and press against the guide rod, opening the two closed plates in opposite directions. As the sliding column continues to move upwards, it carries the vortex sprinkler and multiple blades upwards, allowing them to exit the nozzle pipe. When the tops of the two wedge-shaped blocks contact the top surface of the groove, the sliding column is stopped. As water continues to flow, water pressure acts on the surface of the suspended ball, causing the surface of the suspended ball to detach from the circular groove. The suspended ball moves upwards, carrying the sliding rod upwards, thus raising the lifting rod. As the sealing head moves and disengages from the protrusion, water from inside the watering device enters the inlet channel through the circular groove, then enters the interior of the rotary sprinkler. The water is then sprayed out through multiple watering holes. Gas from the air outlet acts on the surface of the blades, causing them to rotate and rotate within the rotating groove. Thus, the rotary sprinkler simultaneously sprays water and rotates, achieving the effect of swirling irrigation for garden lawns. Compared to traditional partial irrigation equipment, this device allows the rotary sprinkler to spray water and rotate simultaneously, solving the problem of insufficient or inadequate irrigation in traditional lifting sprinkler heads due to gaps in the water outlets. The rotary sprinkler ensures the quality of irrigation for garden lawns.

[0016] 2) When using this water-saving irrigation equipment for agricultural landscaping, after the irrigation is completed, the water pump stops working. At this time, the suspended ball resets under the action of the first spring and seals with the circular groove. The sealing head and the protrusion achieve a seal. Then, the second spring resets the wedge block, causing the sliding column to reset. The reset of the sliding column makes the sprayer hidden inside the nozzle pipe. At this time, the two guide rods reset under the action of the third spring, causing the two sealing plates to reset. After the two sealing plates reset and dock, they seal and protect the sprayer, preventing grass clippings, leaves, and other solids from clogging the watering holes, ensuring normal water output from the watering holes, and thus ensuring the normal use of the irrigation equipment next time.

Detailed Implementation

[0019] Please see Figure 1 - Figure 9A water-saving irrigation device for agricultural landscaping includes a watering device 1 installed on the ground, which irrigates the agricultural landscaping. Multiple nozzle pipes 2 are fixedly installed on the top surface of the watering device 1 and communicate with it. A groove 3 is formed inside the nozzle pipe 2, and a matching sliding column 4 is slidably connected inside the groove 3. The sliding column 4 and the groove 3 are sealed together. A rotating groove 5 is formed on the top surface of the sliding column 4, and a matching rotating ring 6 is rotatably connected inside the rotating groove 5. The rotating groove 5 and the rotating ring 6 are sealed together to prevent leakage during the process of water entering the sprinkler 7 through the inlet channel 9. A sprinkler 7 is fixedly installed on the top surface of the rotating ring 6, and several watering holes 8 are formed on the surface of the sprinkler 7. Water from the watering holes 8 irrigates the agricultural landscaping. The sliding column 4 has an internal water inlet channel 9, with a protrusion 10 fixedly installed on the inner wall of the water inlet channel 9. A fixing ring 11 is fixedly installed inside the water inlet channel 9, and a matching sliding rod 12 is slidably connected inside the fixing ring 11. The sliding rod 12 slides within the fixing ring 11 to guide its movement. A lifting rod 13 is fixedly installed on the top surface of the sliding rod 12. The function of the lifting rod 13 is to move the sealing head 14 away from the protrusion 10, thereby opening the water inlet channel 9 to ensure water passage. A sealing head 14 that seals with the protrusion 10 is fixedly installed on the top surface of the lifting rod 13. A base plate 15 is fixedly installed on the bottom surface of the sliding column 4, and a through-hole circular groove 16 is formed on the surface of the base plate 15. A sealing head 14 that seals with the protrusion 10 is fixedly installed on the bottom surface of the sliding rod 12. The 6-phase sealed suspension ball 17 is a conventional suspension ball 17 in the prior art. The surface of the slide rod 12 is fitted with a first spring 18 for its movement reset (the elastic force of the first spring 18 is greater than the elastic force of the two second springs 23). Water is pumped into the inlet pipe 35 by the water pump, and then the water enters the watering device 1 through the inlet pipe 35. The water acts on the bottom surface of the base plate 15 through the opening 34. At this time, the base plate 15 moves upward under water pressure, which moves the slide column 4, causing the two wedge blocks 22 to move upward and squeeze the guide rod 24, causing the two sealing plates 26 to move in opposite directions and open. As the slide column 4 continues to move upward, it moves the sprayer 7 and multiple blades 31 upward and leaks out of the nozzle pipe 2. When the two wedges After the top of the block 22 contacts the top surface of the inner wall of the slot 21, the sliding column 4 is limited. As water continues to be delivered, water pressure acts on the surface of the suspended ball 17, causing the surface of the suspended ball 17 to detach from the circular groove 16. The suspended ball 17 moves upward, carrying the sliding rod 12 upward, causing the lifting rod 13 and the sealing head 14 to move. After the sealing head 14 moves and detaches from the protrusion 10, the water inside the watering device 1 enters the water inlet channel 9 through the circular groove 16, and then enters the interior of the rotary sprinkler 7. At this time, the water is sprayed out through multiple watering holes 8, and the gas sprayed out by the air outlet 32 ​​acts on the surface of the blade 31. At this time, the blade 31 rotates, causing the rotating ring 6 to rotate in the rotating groove 5. At this time, the rotary sprinkler 7 sprays water and rotates at the same time, realizing the effect of rotary watering of garden lawns.Compared to traditional partial irrigation equipment, this irrigation equipment allows the rotary sprinkler 7 to spray water and rotate simultaneously, solving the problem of insufficient or inadequate irrigation in garden areas due to the gaps in the water outlets of traditional lifting sprinklers. The rotary sprinkler 7 achieves rotary irrigation of the garden lawn, ensuring the quality of irrigation. After the irrigation equipment completes its work, the water pump stops. At this time, the suspended ball 17 resets under the action of the first spring 18 and seals with the circular groove 16. The sealing head 14 and the protrusion 10 also achieve a seal. Then, the second spring 23, along with the wedge block 22, resets, causing the sliding column 4 to move and reset. The reset of the sliding column 4 allows the rotary sprinkler 7 to be hidden inside the sprinkler pipe 2. At this time, the two guide rods 24 reset under the action of the third spring 27, causing the two sealing plates 26 to move and reset. After the two sealing plates 26 move towards each other and reconnect, they seal and protect the rotary sprinkler 7, preventing grass clippings, leaves, and other solids from clogging the water outlets 8, ensuring normal water output from the water outlets 8, and thus ensuring the normal use of the irrigation equipment next time.

[0020] Please see Figure 6 - Figure 9 Two connecting rods 19 are provided between the fixing ring 11 and the inner wall of the water inlet channel 9. The fixing ring 11 is fixedly connected to the inner wall of the water inlet channel 9 through the connecting rods 19. One end of the first spring 18 is fixedly connected to the surface of the suspended ball 17, and the other end of the first spring 18 is fixedly connected to the bottom surface of the fixing ring 11. The first spring 18 is used for the movement reset of the suspended ball 17 and to match the circular groove 16 for sealing.

[0021] Please see Figure 3 - Figure 6 Two mounting plates 20 are fixedly installed on the surface of the nozzle pipe 2. The interior of each mounting plate 20 is provided with a slot 21 that communicates with the slide groove 3. The interior of each slot 21 is slidably connected with a matching wedge block 22. The two wedge blocks 22 are fixedly connected to the surface of the slide column 4. A second spring 23 is elastically connected between the wedge block 22 and the slot 21. The second spring 23 is used for the reset movement of the wedge block 22, so that the slide column 4 moves to reset and retracts the sprayer 7 into the slide groove 3. One end of the second spring 23 is fixedly connected to the inner wall of the slot 21, and the other end of the second spring 23 is fixedly connected to the wedge block 22.

[0022] Please see Figure 3 - Figure 9Both slots 21 have through-type guide rods 24 slidably connected to their inner walls. The guide rods 24 are used to guide the movement of the connecting frame 25. One end of each guide rod 24 is fixedly installed with a connecting frame 25. One end of each connecting frame 25 is fixedly installed with a closing plate 26. The two closing plates 26 move towards each other and reconnect to reset, thus protecting the sprayer 7 and preventing debris from clogging the watering hole 8. The surfaces of both guide rods 24 are fitted with a third spring 27 for resetting. One end of the third spring 27 is fixedly connected to the surface of the mounting plate 20, and the other end of the third spring 27 is fixedly connected to the connecting frame 25. The third spring 27 is used to reset the movement of the connecting frame 25.

[0023] Please see Figure 6 The wedge block 22 includes a ramp surface 29 and a plane 30, which are connected. The ramp surface 29 is in contact with one end of the guide rod 24. The two wedge blocks 22 move upward, causing the ramp surface 29 to squeeze the guide rod 24. After being squeezed, the two guide rods 24 move, carrying the two connecting frames 25 and the sealing plate 26. At this time, the third spring 27 is stretched. When the guide rod 24 moves to the plane 30, the two sealing plates 26 move in opposite directions and open. As the sliding column 4 continues to move upward, it carries the sprayer 7 and multiple blades 31 upward, which leak out of the nozzle pipe 2.

[0024] Please see Figure 7 Multiple blades 31 are fixedly installed on the surface of the rotating ring 6. Airflow nozzles 28 for blowing the blades 31 are fixedly installed on the surfaces of the two sealing plates 26. The airflow nozzles 28 are obliquely arranged corresponding to the blades 31. The airflow nozzles 28 are conventional airflow nozzles 28 in the prior art.

[0025] Please see Figure 6 and Figure 7 The airflow nozzle 28 includes an air outlet 32 ​​and an air inlet pipe 33. The air outlet 32 ​​is correspondingly set with the deflector 31. After the sprayer 7 exits the nozzle pipe 2, the deflector 31 and the air outlet 32 ​​are positioned to correspond, so that the gas sprayed from the air outlet 32 ​​acts on the surface of the deflector 31 to a greater extent.

[0026] Please see Figure 2 The surface of the watering device 1 has the same number of openings 34 as the nozzle pipe 2. After the suspended ball 17 is separated from the circular groove 16, the water inlet channel 9 is connected to the watering device 1 through the openings 34. A water inlet pipe 35 connected to it is fixedly installed on one end of the surface of the watering device 1.

[0027] Please see Figure 1 and Figure 2A mounting bracket 36 is fixedly installed on the surface of the watering device 1. An air pump 37 is fixedly installed on the surface of the mounting bracket 36. The air outlet of the air pump 37 is sealed and connected to the air inlet pipe 33 through a multi-port pipe. The multi-port pipe is a conventional multi-port pipe in the prior art. The air pump 37 is a conventional air pump 37 in the prior art. The water pump is a conventional water pump in the prior art (not shown in the figure). The air pump 37 and the water pump are controlled by a controller. The operation of the air pump 37 and the water pump by the controller is prior art and will not be described in detail here.

[0028] Please see Figure 1 and Figure 2 The bottom surface of the watering device 1 is provided with two supports 38 for supporting it. The two supports 38 are in contact with the bottom surface and are fixedly connected to the bottom surface of the watering device 1.

[0029] The usage steps of this invention are as follows: When using this water-saving irrigation equipment for agricultural landscaping, the watering device 1 is installed on the agricultural landscaping ground that needs irrigation via two supports 38, and the inlet pipe 35 is sealed to the outlet of an existing water pump (the water pump is a conventional water pump in the prior art, and the overall water pressure is controlled by the water pump). Initially, the suspended ball 17 is sealed to the circular groove 16 under the action of the first spring 18 (note that the elastic force of the first spring 18 is much greater than the elastic force of the two second springs 23). When irrigating the landscaping, the water pump works to deliver water into the inlet pipe 35, and then the water enters the watering device 1 through the inlet pipe 35. The water acts on the bottom surface of the base plate 15 through the opening 34. At this time, the base plate 15 moves upward under water pressure, which moves the sliding column 4. The sliding column 4 moves upward, causing the two wedge blocks 22 to move upward as well. The upward movement of the two wedge blocks 22 causes the ramp surface 29 to press against the guide rod 24. After being pressed, the two guide rods 24 move, causing the two connecting frames 25 and the sealing plate 26 to move. At this time, the third spring 27 is stretched. When the guide rod 24 moves to the plane 30, the two sealing plates 26 move in opposite directions and open. As the sliding column 4 continues to move upward, it causes the spray nozzle 7 and multiple deflectors 31 to move upward, exposing the nozzle pipe 2. At this time, the suspended ball 17 is sealed with the circular groove 16 under the action of the first spring 18, and the protrusion 10 is sealed with the sealing head 14. When the tops of the two wedge blocks 22 contact the top surface of the inner wall of the slot 21, the sliding column 4 is limited. At this time, the position and height of the multiple deflectors 31 are relative to the airflow nozzle 28. The air outlet 32 ​​is the same. As water continues to be delivered, water pressure acts on the surface of the suspended ball 17, causing the surface of the suspended ball 17 to detach from the circular groove 16. The suspended ball 17 moves upward, carrying the sliding rod 12 to slide upward inside the fixed ring 11, compressing the first spring 18. The sliding rod 12 moves upward, carrying the lifting rod 13 and the sealing head 14. After the sealing head 14 moves and detaches from the protrusion 10, the water inside the watering device 1 enters the water inlet channel 9 through the circular groove 16, and then enters the sprinkler 7. At this time, the water is sprayed out through multiple watering holes 8. During the process of water being sprayed out through multiple watering holes 8, the air pump 37 works, and the gas enters the interior of each airflow nozzle 28 through the existing multi-way pipe. Then the gas is sprayed out from the air outlet 32 ​​of the airflow nozzle 28. The gas ejected from head 32 acts on the surface of blade 31. At this time, blade 31 rotates, causing the rotating ring 6 to rotate within the rotating groove 5. Simultaneously, the sprinkler 7 sprays water while rotating, achieving the effect of swirling irrigation for the garden lawn. After the irrigation equipment completes, the water pump stops working. At this time, the suspended ball 17 resets under the action of the first spring 18 and seals with the circular groove 16. The sealing head 14 and the protrusion 10 achieve a seal. Then, the second spring 23 resets the wedge block 22, causing the sliding column 4 to move and reset. The reset of the sliding column 4 allows the sprinkler 7 to be hidden inside the nozzle pipe 2. At this time, the two guide rods 24 reset under the action of the third spring 27, causing the two sealing plates 26 to move and reset. After the two sealing plates 26 move towards each other and reconnect, they seal and protect the sprinkler 7.The scheme uses a water pump to deliver water into the inlet pipe 35, and then the water enters the watering device 1 through the inlet pipe 35. The water acts on the bottom surface of the base plate 15 through the opening 34. At this time, the base plate 15 moves upward under water pressure, which moves the sliding column 4, causing the two wedge blocks 22 to move upward and squeeze the guide rod 24, causing the two closing plates 26 to move in opposite directions and open. As the sliding column 4 continues to move upward, it moves the sprayer 7 and multiple blades 31 upward, exposing the nozzle pipe 2. When the top of the two wedge blocks 22 contacts the top surface of the inner wall of the slot 21, the sliding column 4 is limited. As water continues to be delivered, water pressure acts on the surface of the suspended ball 17, causing the surface of the suspended ball 17 to detach from the circular groove 16. The suspended ball 17 moves upward, causing the sliding rod 12 to slide upward, which in turn causes the lifting rod 13 and the sealing head 14 to move. After the sealing head 14 moves and detaches from the protrusion 10, the water inside the watering device 1 enters the water inlet channel 9 through the circular groove 16, and then enters the interior of the sprayer 7. At this time, the water is sprayed out through multiple watering holes 8, and the gas sprayed out by the air outlet 32 ​​acts on the surface of the deflector 31. At this time, the deflector 31 rotates, causing the rotating ring 6 to rotate in the rotating groove 5. At this time, the rotary sprinkler 7 sprays water and rotates simultaneously, achieving the effect of rotary watering the garden lawn. Compared with traditional partial irrigation equipment, this irrigation equipment can achieve the effect of rotary sprinkler 7 spraying water and rotating simultaneously, solving the problem that the spacing of the water outlet holes of traditional lifting sprinklers leads to insufficient irrigation of garden areas or very low irrigation volume. The rotary sprinkler 7 achieves rotary watering of the garden lawn, ensuring comprehensive irrigation of the garden lawn, and thus ensuring the irrigation quality of the garden lawn; when the watering equipment completes irrigation, the water pump stops working, and at this time, the suspended ball 17, under the action of the first spring 18... The reset and sealing mechanism 16 seals the nozzle, and the sealing head 14 seals the protrusion 10. Then, the second spring 23, carrying the wedge block 22, resets the nozzle, causing the sliding column 4 to move back to its original position. The reset of the sliding column 4 allows the sprinkler 7 to be hidden inside the nozzle pipe 2. At this time, the two guide rods 24, under the action of the third spring 27, reset, causing the two sealing plates 26 to move back to their original position. After the two sealing plates 26 move towards each other and reconnect, they seal and protect the sprinkler 7, preventing grass clippings, leaves, and other solids from clogging the watering hole 8, ensuring normal water output from the watering hole 8, and thus ensuring the normal use of the watering equipment next time.
