Description

Technical Field

[0001] The invention relates to the technical field of seedling drip irrigation devices, and specifically relates to a water-saving drip irrigation device special for seedlings. Background Art

[0002] Drip irrigation uses plastic pipes to deliver water to the roots of seedlings through the orifices or drippers on the capillary tubes for local irrigation. It has a higher water-saving and yield-increasing effect. It can be used for irrigation of seedlings, vegetables, cash crops and greenhouses. It can also be used for irrigation of field crops in drought and water-scarce areas. At present, the orifice of the drip irrigation device is prone to scaling and clogging, so it is necessary to regularly check the blockage of the orifice and clean it in time. For example, the Chinese invention patent with the patent application number "CN202310088517.X" provides a drip irrigation water-saving device for planting fruit seedlings. When the device is in use, after the drip irrigation control mechanism moves to the top of the drip irrigation water-saving mechanism, the guide column control plate drives the metal contact rod close to the contact surface of the magnet water seal, so that the water flow area of ​​the drip irrigation hole is increased, and the poor drip irrigation of the drip irrigation hole here is improved. During the movement of the drip irrigation water guide column, it will contact the drip irrigation hole, and the scaled impurities on the drip irrigation hole can be removed.

[0003] The disadvantage of the device is that a drip irrigation control mechanism is provided on the drip irrigation branch pipe.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Embodiment 1

[0041] See also Figure 1-18The present invention provides a technical solution: a water-saving drip irrigation device for seedlings, comprising a drip irrigation pipe 1, a plurality of dredging components 2, two support frames 3 and a controller 4. The bottom of the drip irrigation pipe 1 is provided with a plurality of evenly distributed drip irrigation holes 11, and the plurality of dredging components 2 correspond to the positions of the plurality of drip irrigation holes 11 one by one. The dredging component 2 comprises an assembly box 21, a conical block 22, two elastic cleaning rods 23 and a driving component 26. There is a gap between the elastic cleaning rod 23 and the inner wall of the drip irrigation pipe 1, the elastic cleaning rod 23 is an arc rod, and a first elastic reset rod 24 and a second elastic reset rod 25 are provided on the inner concave surface of the elastic cleaning rod 23, and the output end of the driving component 26 is connected to the first end of the conical block 22. The two support frames 3 are respectively fixedly arranged at the two ends of the drip irrigation pipe 1, and can lift the drip irrigation pipe 1 to ensure that the drip irrigation holes 11 and the dredging components 2 will not directly contact the soil. The plurality of dredging components 2 are electrically connected to the controller 4, and the controller 4 can control the running state of the dredging components 2.

[0042] See also Figure 1-6 and Fig.18 When the present invention is in use, a plurality of drip irrigation pipes 1 are arranged in parallel, and water is supplied by an external water source (such as a water tank, a water pump, etc.). The external water source enters the interior of the drip irrigation pipe 1 through the water inlet 12 on the drip irrigation pipe 1, and flows out from a plurality of drip irrigation holes 11. Since a conical block 22 is provided directly below the drip irrigation hole 11, the water flowing out of the drip irrigation hole 11 flows downward along the outer surface of the conical block 22, and finally drips to the root of the seedling to complete the drip irrigation work.

[0043] See also Figure 1-6 and Fig.18 When some drip irrigation holes 11 are blocked by impurities, the controller 4 controls the dredging components 2 at these drip irrigation holes 11 to start working. The driving component 26 drives the conical block 22 to move downward, and the conical block 22 controls the two elastic cleaning rods 23 to move downward through the two second elastic reset rods 25. Since the elastic cleaning rod 23 is also connected to the assembly box 21 through the two first elastic reset rods 24, and the assembly box 21 is fixed on the inner top surface of the drip irrigation pipe 1, during the downward movement of the conical block 22, the first elastic reset rod 24 and the second elastic reset rod 25 will both undergo elastic deformation and store elastic potential energy. The two elastic cleaning rods 23 move closer to each other while moving downward, pushing the scaled impurities at the drip irrigation hole 11 to the center of the drip irrigation hole 11. When the two elastic cleaning rods 23 are attached together, the two elastic cleaning rods 23 can enter the interior of the drip irrigation hole 11 together, and push the scaled impurities at the center of the drip irrigation hole 11 out of the drip irrigation hole 11, so that the scaled impurities are separated from the drip irrigation pipe 1, and the cleaning work of the drip irrigation hole 11 is completed. Then the driving assembly 26 drives the conical block 22 to move upward, and the first elastic reset rod 24 and the second elastic reset rod 25 release their elastic potential energy, elastically deform and restore to their original state, and the two elastic cleaning rods 23 move away from each other while moving upward to achieve reset.

[0044] In the present invention, each dredging assembly 2 can independently complete the cleaning of impurities in the drip irrigation hole 11, so the present invention can clean multiple drip irrigation holes 11 at the same time, thereby improving the efficiency of cleaning the drip irrigation holes 11. Since the elastic cleaning rod 23 is an arc rod, even if two elastic cleaning rods 23 enter the interior of the drip irrigation hole 11 together, the water in the drip irrigation pipe 1 can flow through the center of the two elastic cleaning rods 23 to the side wall of the conical block 22, so during the cleaning process of the drip irrigation hole 11, the drip irrigation work will not be interrupted.

[0045] See also Figure 1-10 and Fig.18 The present invention further includes an auxiliary cleaning component 5, which is electrically connected to the controller 4. The auxiliary cleaning component 5 includes an air supply pipe 51, two ventilation hoses 52, two first electrically controlled valves 53, two second electrically controlled valves 54, two elastic air bags 55 and two arc-shaped scraper plates 56. A first air storage cavity 211 is provided inside each assembly box 21, and a second air storage cavity 231 is provided inside the two elastic cleaning rods 23. Several first air storage cavities 211 are connected to the inside of the air supply pipe 51, and the two ends of the ventilation hose 52 are connected to the inside of the first air storage cavity 211 and the top of the second air storage cavity 231 respectively. The first electrically controlled valve 53 can control whether the gas in the first air storage cavity 211 enters the ventilation hose 52, and the second electrically controlled valve 54 can control whether the gas in the second air storage cavity 231 is discharged. When the present invention is in use, gas is supplied through an external gas source (such as a gas supply pipe, a gas supply pump, etc.), and the gas enters the first air storage cavity 211 inside the assembly box 21 through the air supply pipe 51.

[0046] See also Figure 1-10In the cleaning work of the drip irrigation hole 11, after the two elastic cleaning rods 23 move downward at the same time, the two elastic cleaning rods 23 will first contact the inner bottom surface of the drip irrigation pipe 1. At this time, the two elastic cleaning rods 23 have not yet been attached. The controller 4 controls the first electric control valve 53 to open, and the gas in the first air storage cavity 211 enters the second air storage cavity 231 through the ventilation hose 52. Since the second air storage cavity 231 is connected to the inside of the elastic air bag 55, the elastic air bag 55 expands, pushing most of the loose impurities to move to the middle of the two elastic cleaning rods 23, and the first cleaning of impurities is achieved. Next, the elastic cleaning rods 23 move closer to each other and fit together, and enter the interior of the drip irrigation hole 11 together. In this process, the remaining stubborn impurities will be pushed by the elastic cleaning rods 23, and the stubborn impurities will also move to the middle of the two elastic cleaning rods 23, and the second cleaning of impurities is achieved. The arc-shaped scraper plates 56 on the top of the two elastic cleaning rods 23 can push the impurities in the middle of the cleaning rods 23 downward, so that the scraped impurities can be discharged to the outside of the drip irrigation pipe 1 through the drip irrigation hole 11. The controller 4 then controls the first electrically controlled valve 53 to close, controls the second electrically controlled valve 54 to open, the gas in the second air storage cavity 231 is discharged, the elastic airbag 55 shrinks and resets, and the second electrically controlled valve 54 is finally closed.

[0047] See also Figure 1-10 The assembly box 21 is a shuttle-shaped structure. When the water entering the drip irrigation pipe 1 flows in the length extension direction of the drip irrigation pipe 1, the assembly box 21 will not hinder the water flow. The water flow can quickly pass through each dredging component 2 to ensure that each drip irrigation hole 11 has enough water flowing out. The top of the drip irrigation pipe 1 is provided with an assembly hole 13. The shape of the assembly hole 13 matches the shape of the assembly box 21. The assembly box 21 is detachably connected to the drip irrigation pipe 1. The assembly box 21 can be removed to overhaul the present invention and can also be used to discharge excess gas.

[0048] Embodiment 2

[0049] Based on Example 1, please refer to Figure 1-12 and Fig.18 The driving assembly 26 includes a watertight cylinder 261, a first electric telescopic rod 262, a driving rod 263, a first transmission ring 264 and a second transmission ring 265. The watertight cylinder 261 is installed on the outer bottom surface of the assembly box 21, the first electric telescopic rod 262 is arranged inside the watertight cylinder 261, the output end of the first electric telescopic rod 262 is connected to the first end of the driving rod 263, the second end of the driving rod 263 is connected to the first transmission ring 264, the second transmission ring 265 is fixedly arranged on the end face of the first end of the conical block 22, and the second transmission ring 265 is sleeved inside the first transmission ring 264.

[0050] See also Figure 1-12When the drip irrigation hole 11 is not blocked, the driving assembly 26 does not work, and the water in the drip irrigation pipe 1 can flow downward along the outer surface of the water-blocking tube 261 to the outer wall of the conical block 22, and the interior of the water-blocking tube 261 will not be filled with water. When the drip irrigation hole 11 is blocked, the controller 4 controls the first electric telescopic rod 262 to extend, and drives the first transmission ring 264 to move downward through the driving rod 263. When the first transmission ring 264 abuts against the top surface of the conical block 22, it pushes the conical block 22 to move downward, thereby driving the first elastic reset rod 24 and the second elastic reset rod 25 to undergo elastic deformation, and perform subsequent cleaning work. When the cleaning work is completed, the controller 4 controls the first electric telescopic rod 262 to shorten, and drives the first transmission ring 264 to move downward and upward through the driving rod 263. The first transmission ring 264 applies a pulling force to the second transmission ring 265, and pulls the conical block 22 upward and resets through the second transmission ring 265.

[0051] See also Figure 1-12 Since the second transmission ring 265 is sleeved inside the first transmission ring 264, the conical block 22 and the driving rod 263 are not directly connected, and the conical block 22 can swing. Therefore, when drip irrigation is performed to the roots of the seedlings, the bottom direction of the conical block 22 can be manually adjusted, so that the present invention can perform drip irrigation more accurately.

[0052] Embodiment 3

[0053] Based on Example 1, please refer to Figure 1-18 The present invention further includes a blockage identification component 6, which is disposed below the drip irrigation pipe 1 and is electrically connected to the controller 4. The blockage identification component 6 includes a water storage box 61, a plurality of water diversion components 62, and a plurality of liquid sensors 63. The water storage box 61 is provided with a plurality of water storage chambers 611, and the plurality of water diversion components 62 are respectively disposed in the plurality of water storage chambers 611. The output ends of the plurality of water diversion components 62 are respectively abutted against the middle side walls of the plurality of conical blocks 22. The plurality of liquid sensors 63 are respectively disposed in the plurality of water storage chambers 611, and there is a gap between the liquid sensor 63 and the bottom surface of the water storage chamber 611. When the present invention is in use, it is possible to determine whether the drip irrigation hole 11 is blocked by the blockage identification component 6.

[0054] See also Figure 1-18When the present invention starts drip irrigation, since the output end of the water diversion component 62 abuts against the middle side walls of several conical blocks 22, part of the water flowing downward from the outer wall of the conical block 22 will flow onto the water diversion component 62, and flow into the water storage chamber 611 along the water diversion component 62 for storage. The controller 4 can control the output end of the water diversion component 62 to continuously move back and forth toward and away from the conical block 22, and the interval time can be set by the operator. When the output end of the water diversion component 62 moves away from the conical block 22, the water on the outer wall of the conical block 22 cannot flow into the water storage chamber 611 through the output end of the water diversion component 62. The controller 4 pre-stores the shortest time for the water level in the water storage chamber 611 to rise until it contacts the liquid sensor 63 when the drip irrigation hole 11 is not blocked.

[0055] See also Figure 1-18 As more and more water flows into the water storage chamber 611, when the water surface rises and contacts the liquid sensor 63, the liquid sensor 63 sends a signal to the controller 4, and the controller 4 determines whether the current time is extended compared with the preset time. If the time is not extended, it is determined that the drip irrigation hole 11 is not blocked. If the time is indeed extended, it is determined that the drip irrigation hole 11 is blocked, and it is necessary to control the dredging component 2 and the auxiliary cleaning component 5 to work and clean the drip irrigation hole 11.

[0056] See also Figure 1-18 The water diversion assembly 62 includes a water diversion member 621 and a second electric telescopic rod 622. A sidewall of the water storage box 61 close to the conical block 22 is provided with an avoidance opening 612. The second electric telescopic rod 622 is fixedly arranged on the inner sidewall of the water storage box 61 away from the conical block 22. When the second electric telescopic rod 622 is extended, the second end of the water diversion member 621 passes through the avoidance opening 612 and abuts against the middle sidewall of the conical block 22. At this time, the first end of the water diversion member 621 is still inside the water storage box 61, ensuring that the water flowing to the water diversion assembly 62 can smoothly flow into the water storage chamber 611 for storage. The width of the avoidance opening 612 is greater than the width of the water diversion member 621, so the water diversion member 621 will not contact the water storage box 61, and the water flowing to the water diversion assembly 62 will not flow to the outer surface of the water storage box 61.

[0057] See also Figure 1-18The water guide member 621 includes a guide plate 6211 and a transmission plate 6212. The guide plate 6211 is tilted, and the two ends of the transmission plate 6212 are respectively connected to the output end of the second electric telescopic rod 622 and the guide plate 6211. Therefore, when the second electric telescopic rod 622 is extended or shortened, the guide plate 6211 can be driven to reciprocate through the transmission plate 6212, so that the guide plate 6211 is close to or away from the middle side wall of the conical block 22. The top of the guide plate 6211 is provided with a water guide groove 62111, and the first end of the guide plate 6211 is provided with an arc-shaped fitting surface 62112. When the guide plate 6211 contacts the conical block 22, the arc-shaped fitting surface 62112 fits with the middle side wall of the conical block 22. The water on the middle side wall of the conical block 22 can enter the water diversion groove 62111 and slide down along the water diversion groove 62111 into the water storage chamber 611. The transmission plate 6212 is an inverted U-shaped structure, and the transmission plate 6212 will not hinder the water in the water diversion groove 62111. The liquid sensor 63 is arranged directly below the second electric telescopic rod 622, and the top height of the liquid sensor 63 is lower than the bottom height of the avoidance opening 612. The drainage plate 6211 will not contact the liquid sensor 63, so the water on the drainage plate 6211 will not drip onto the liquid sensor 63, and before the water in the water storage chamber 611 rises, the liquid sensor 63 will not send a signal to the controller 4.

[0058] See also Figure 1-18 The blockage identification component 6 also includes a plurality of first water outlet pipes 64, a plurality of second water outlet pipes 66 and a drain pipe 68. The plurality of first water outlet pipes 64 and the plurality of second water outlet pipes 66 are all arranged below the water storage box 61, and the first water outlet pipes 64 and the second water outlet pipes 66 are both inclinedly arranged, and the first water outlet pipes 64 and the second water outlet pipes 66 together form an inverted V shape. The second end of the first water outlet pipe 64 faces the second end of the conical block 22, a third electrically-controlled valve 65 is provided in the middle of the first water outlet pipe 64, and a fourth electrically-controlled valve 67 is provided in the middle of the second water outlet pipe 66, and the plurality of second water outlet pipes 66 are all connected to the interior of the drain pipe 68.

[0059] See also Figure 1-18When the present invention is in use, the third electrically controlled valve 65 and the fourth electrically controlled valve 67 are first in a closed state. When the water flowing into the water storage chamber 611 contacts the liquid sensor 63, if the controller 4 determines that the drip irrigation hole 11 at the location is not blocked, the fourth electrically controlled valve 67 at the location is opened, and the water in the water storage chamber 611 enters the drain pipe 68 through the second outlet pipe 66 and is discharged. If the controller 4 determines that the drip irrigation hole 11 at the location is blocked, the third electrically controlled valve 65 at the location is opened, and the water in the water storage chamber 611 enters the first outlet pipe 64, and finally drains to the root position of the seedlings below the conical block 22 at the location to perform a water replenishment operation. Then the controller 4 controls the dredging component 2 and the auxiliary cleaning component 5 at the location to work and clean the drip irrigation hole 11.
