TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural equipment, and particularly relates to a high-efficiency utilization drip irrigation equipment and method for farmland precipitation in a dry area. BACKGROUND

[0002] The farmland in a dry area refers to a farmland in a drought, semi-drought or seasonal drought area, which is difficult to meet the normal growth demand of crops due to rare precipitation, strong evaporation and water resource shortage. The annual precipitation in such an area is usually less than 400 mm, and the temporal and spatial distribution of precipitation is uneven, resulting in that agricultural production is highly dependent on irrigation, but water resource shortage seriously restricts sustainable development of agriculture. The high-efficiency utilization drip irrigation equipment for farmland precipitation in a dry area is a water-saving irrigation system integrating rainwater collection and drip irrigation, which significantly improves the utilization rate of precipitation and crop yield, and is particularly suitable for arid and semi-arid areas.

[0003] The conventional drip irrigation equipment usually relies on a single water collection structure, such as a fixed rainwater collection shed or a ground water collection tank, and the water collection area cannot be dynamically adjusted. In a dry area, rainfall is usually short-time heavy rainfall, and it is difficult for the fixed water collection area to quickly capture a large amount of rainwater, resulting in low water collection efficiency. In addition, the water collection port or filter device of the conventional drip irrigation equipment is easily blocked by impurities such as leaves and silt, and needs to be cleaned regularly by manual operation. After each rainfall, impurities are more seriously accumulated, and the frequency of manual cleaning is higher. Therefore, the high-efficiency utilization drip irrigation equipment and method for farmland precipitation in a dry area are proposed. SUMMARY

[0004] The purpose of the present application is to solve the problems in the prior art that the fixed water collection area is difficult to quickly capture a large amount of rainwater, resulting in low water collection efficiency, and the water collection port or filter device of the conventional drip irrigation equipment is easily blocked by impurities such as leaves and silt, and to propose a high-efficiency utilization drip irrigation equipment and method for farmland precipitation in a dry area.

[0005] In order to achieve the above purpose, the present application adopts the following technical scheme: The utility model provides a kind of efficient use of precipitation drip irrigation equipment in arid farmland, including collection box, the side of the collection box is equipped with first water pump, the output end of the first water pump is equipped with irrigation pipe, the outside of the irrigation pipe is equipped with multiple drip irrigation heads, the inner side of the collection box is rotatably connected with filter plate, the upper portion of the collection box is equipped with collection hopper, the collection box is provided with expansion collection assembly, the expansion collection assembly includes the rotatable connection of multiple first collection plates of the side of the collection box, the second water pump installed in the side of the collection box, the first conveying pipe installed in the input end of the second water pump, the second conveying pipe installed in the bottom of the first conveying pipe, the third conveying pipe installed in the output end of the second water pump, the rotatable connection of the second collection plate of the upper portion of the collection box, the drive unit arranged in the side of the collection box, drive unit rotates multiple first collection plates and ground contact and drive second collection plate to rotate to the side of collection hopper, second collection plate no longer blocks collection hopper, the second water pump starts and passes through first conveying pipe and second conveying pipe and is conveyed to the collection box by third conveying pipe, the collection box is provided with centrifugal assembly, the centrifugal assembly includes the second support box installed in the inner side of the collection box, the third rotating rod and the fourth rotating rod rotatably connected in the inner side of the second support box, the linkage unit arranged in the second support box, when the second collection plate rotates, third rotating rod is rotated by linkage unit, when third rotating rod rotates, filter plate is rotated by fourth rotating rod.

[0006] The above technical solution further comprises: The side of the collection box is equipped with multiple support plates, the side of the support plate is rotatably connected with first rotating rod, the side of the first rotating rod is equipped with connecting plate, and the first collection plate is installed on the side of the connecting plate away from the first rotating rod.

[0007] The drive unit includes the first support box installed in the side of the collection box, the second water pump is installed in the inner side of the first support box, the servo motor is installed in the inner side of the first support box, the threaded rod is installed in the output end of the servo motor close to the first collection plate, the sliding plate is slidably arranged in the side of the collection box, the threaded connection is between the sliding plate and the threaded rod, and the acting force generated when the threaded rod rotates drives the sliding plate to move downward.

[0008] The drive unit further includes multiple racks installed in the bottom of the sliding plate, the first gear is installed in the end of the first rotating rod away from the support plate, the first gear is engaged with the rack, and the first rotating rod can be driven to rotate by the first gear when the rack moves downward.

[0009] The second rotating rod is rotatably connected between the output end of the servo motor away from the first collection plate and the collection hopper, the second collection plate is installed in the end of the second rotating rod, and the second collection plate can be rotated to the side of the collection hopper when the second rotating rod rotates.

[0010] The linkage unit includes a transmission belt sleeved on the outer side of the third rotating rod and the second rotating rod. A second gear is installed on the outer side of the third rotating rod, and a third gear is installed on the outer side of the fourth rotating rod. The third gear meshes with the second gear.

The impurities accumulated on the surface of the filter plate are thrown out under the action of centrifugal force, which facilitates the next collection operation and eliminates the need for staff to process the impurities after each rainwater collection.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1 like Figure 1 - Figure 6As shown, the present invention proposes a drip irrigation device for efficient utilization of rainfall in arid farmland, comprising a collection box 1, a first water pump 2 mounted on the side of the collection box 1, an irrigation pipe 3 mounted on the output end of the first water pump 2, multiple drip irrigation heads 4 mounted on the outer side of the irrigation pipe 3, a filter plate 6 rotatably connected to the inner side of the collection box 1, a collection hopper 5 mounted on the upper part of the collection box 1, and an extended collection assembly provided on the collection box 1. The extended collection assembly includes multiple first collection plates 16 rotatably connected to the side of the collection box 1, a second water pump 17 mounted on the side of the collection box 1, a first delivery pipe 18 mounted on the input end of the second water pump 17, multiple second delivery pipes 19 mounted on the bottom of the first delivery pipe 18, a third delivery pipe 20 mounted on the output end of the second water pump 17, a second collection plate 22 rotatably connected to the upper part of the collection box 1, and a filter plate 6 rotatably connected to the inner side of the collection box 1. The drive unit is configured to rotate multiple first collection plates 16 to contact the ground and drive the second collection plate 22 to rotate to the side of the collection hopper 5. The second collection plate 22 no longer obstructs the collection hopper 5. The second water pump 17 is started and transports the rainwater collected in the first collection plates 16 to the collection box 1 through the third delivery pipe 20 via the first delivery pipe 18 and the second delivery pipe 19. The collection box 1 is equipped with a centrifugal assembly, which includes a second support box 24 installed inside the collection box 1, a third rotating rod 25 and a fourth rotating rod 28 rotatably connected inside the second support box 24, and a linkage unit installed on the second support box 24. When the second collection plate 22 rotates, it drives the third rotating rod 25 to rotate through the linkage unit. When the third rotating rod 25 rotates, it drives the filter plate 6 to rotate through the fourth rotating rod 28.

[0021] Multiple support plates 12 are installed on the side of the collection box 1. A first rotating rod 13 is rotatably connected to the side of the support plate 12. A connecting plate 15 is installed on the side of the first rotating rod 13. A first collection plate 16 is installed on the side of the connecting plate 15 away from the first rotating rod 13.

[0022] The drive unit includes a first support box 7 mounted on the side of the collection box 1, a second water pump 17 mounted inside the first support box 7, a servo motor 8 mounted inside the first support box 7, a threaded rod 9 mounted on the output end of the servo motor 8 near the first collection plate 16, a sliding plate 10 slidably mounted on the side of the collection box 1, and a threaded connection between the sliding plate 10 and the threaded rod 9. The force generated when the threaded rod 9 rotates drives the sliding plate 10 to move downward.

[0023] The drive unit also includes a plurality of racks 11 mounted on the bottom of the sliding plate 10, and a first gear 14 mounted on the end of the first rotating rod 13 away from the support plate 12. The first gear 14 meshes with the racks 11. When the racks 11 move down, the first rotating rod 13 can be driven to rotate through the first gear 14.

[0024] A second rotating rod 21 is installed at the output end of the servo motor 8 away from the first collecting plate 16. The second rotating rod 21 is rotatably connected to the collecting hopper 5. The second collecting plate 22 is installed at the end of the second rotating rod 21. When the second rotating rod 21 rotates, it can drive the second collecting plate 22 to rotate to the side of the collecting hopper 5.

[0025] The second collecting plate 22 has an opening groove 23 on its side, through which rainwater inside the second collecting plate 22 enters the collecting box 1.

[0026] When the second collecting plate 22 is above the collecting hopper 5, it is in contact with the edge of the collecting hopper 5.

[0027] In this embodiment, when drip irrigation is needed for efficient utilization of rainfall, the servo motor 8 can be activated. The servo motor 8 drives the threaded rod 9 and the second rotating rod 21 to rotate. The force generated by the rotation of the threaded rod 9 causes the sliding plate 10 to move downwards. As the sliding plate 10 moves downwards, it causes multiple collection boxes 1 to move downwards. Since the rack 11 meshes with the first gear 14, the downward movement of the rack 11 can drive the first rotating rod 13 to rotate via the first gear 14. The rotation of the first rotating rod 13 can then drive the first collection plate 16 to rotate via the connecting plate 15 until the first collection plate 16 contacts the ground. Simultaneously, the first... When the second rotating rod 21 rotates, it can drive the second collecting plate 22 to rotate, so that the second collecting plate 22 rotates to the side of the collecting hopper 5. After the second collecting plate 22 collects rainwater, it flows into the collecting hopper 5 through the opening groove 23. At the same time, the second water pump 17 is started. After the second water pump 17 is started, the rainwater in the first collecting plate 16 is transported to the collecting box 1 through the third conveying pipe 20 through the first conveying pipe 18 and the second conveying pipe 19. The rainwater is filtered through the filter plate 6 and enters the inner side of the collecting box 1. In this way, rainwater is collected simultaneously through the collecting hopper 5, the second collecting plate 22 and the first collecting plate 16, thus expanding the rainwater collection area.

[0028] Example 2 like Figure 1 - Figure 6 As shown, based on Embodiment 1, the linkage unit includes a transmission belt 26 sleeved on the outer side of the third rotating rod 25 and the second rotating rod 21. A second gear 27 is installed on the outer side of the third rotating rod 25, and a third gear 29 is installed on the outer side of the fourth rotating rod 28. The third gear 29 meshes with the second gear 27.

[0029] The gear ratio between the second gear 27 and the third gear 29 is 5:1. When the second gear 27 rotates once, it can drive the fourth rotating rod 28 and the filter plate 6 to rotate rapidly five times through the third gear 29.

[0030] In this embodiment, when rainwater collection is no longer needed after rainfall, the second water pump 17 can be directly turned off. Then, the servo motor 8 drives the second rotating rod 21 and the threaded rod 9 to reverse. After the threaded rod 9 reverses, it retracts the first collecting plate 16. After the second rotating rod 21 reverses, it drives the second collecting plate 22 to rotate above the collecting hopper 5, blocking the opening of the collecting hopper 5 and preventing external impurities from contaminating the collected rainwater. At the same time, when the second rotating rod 21 rotates, it can drive the third rotating rod 25 to rotate through the transmission belt 26. The rotation of the third rotating rod 25 can drive the fourth rotating rod 28 to rotate through the second gear 27 and the third gear 29. When rotating, it drives the filter plate 6 to rotate. The gear ratio of the second gear 27 and the third gear 29 is 5:1. Therefore, when the second gear 27 rotates once, the third gear 29 can drive the fourth rotating rod 28 and the filter plate 6 to rotate rapidly five times. The centrifugal force generated by the rapid rotation of the filter plate 6 can quickly throw out the accumulated impurities filtered out on the filter plate 6, which is convenient for the next collection work. When it is necessary to use the rainwater collected in the collection box 1 for drip irrigation, the first water pump 2 is started. The first water pump 2 draws and absorbs the rainwater inside the collection box 1, and then delivers it to multiple drip irrigation heads 4 through the irrigation pipe 3. Finally, the drip irrigation work is carried out through multiple drip irrigation heads 4.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
