[0002] In areas where rainfall is scarce and unevenly distributed, rainwater harvesting irrigation can improve water resource utilization efficiency and alleviate the impact of drought on agricultural production. However, existing rainwater harvesting models often face some drawbacks, such as high technical equipment costs, complex maintenance, and poor environmental adaptability, which may lead to unsatisfactory rainwater harvesting effects. In addition, these models have limited applicability under different terrain and soil conditions, making it difficult to achieve widespread promotion. Therefore, optimizing rainwater harvesting technology to adapt to local conditions and reducing costs and technical requirements are the key to improving the effect of rainwater harvesting irrigation.

[0003] In the prior art, rainwater is collected by burying irrigation devices in combination with laying ground film. The collected rainwater reaches the roots of crops directly, realizing the utilization of small rainfalls. However, it is found during operation that the rainwater is directly sent to the root system through the irrigation device after being gathered, and the irrigation time cannot be controlled, resulting in excessive watering of the root system during the rainy season, causing vigorous growth of trees and affecting tree fruiting. When there is strong wind and sand in the planting area, dust and fallen leaves often appear on the surface of the ground film.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] 1. In the present invention, after a plurality of irrigators are placed around the fruit trees and covered with a water-collecting mulch film, rainwater on the surface of the water-collecting mulch film can flow to the irrigators at a low position. When rainwater spreads to the inside of the leakage cover, rainwater can flow into the inside of the irrigator through the infiltration hole and infiltrate to the outside through the holes on the outer peripheral side of the irrigator. When the amount of rainwater increases and the fruit trees stop to meet the infiltration irrigation needs, the cover plate can be opened.

[0028] 2. In the present invention, the partition part is designed to separate the inside of the leakage cover. By placing nutrient fillers in the accommodating cavity, when rainwater enters the leakage cover, it can be mixed with the slow-release nutrient fillers and then sent into the irrigation device through the bottom seepage hole, which is beneficial to enhance the fertilization effect after rainwater infiltration through the slow-release nutrient fillers. By rotating the cover plate, the leakage holes on the top of the cover plate can be rotated to the tops of different accommodating cavities, so that the contact mode between the water and different accommodating cavities can be adjusted, which is convenient for adjusting to the flow channel of another accommodating cavity without nutrient fillers after sufficient fertilization, and convenient for switching irrigation modes.

[0029] 3. In the present invention, through the designed pressing mechanism, the staff can pull the pressing plate by the handle to drive the slide bar to slide outside the slide bar. When the pressing plate moves to expand the gap of the supporting seat, the reserved opening on the top of the water-collecting membrane can be conveniently placed on the top side of the supporting seat. The water-collecting membrane is pressed and closed after the pressing plate is placed in the supporting seat, so that the water-collecting membrane and the irrigation device can be quickly connected and arranged. The elastic force of the second spring can keep the pressing plate closed on the supporting seat to fully close the water-collecting membrane, so as to prevent the water-collecting membrane from being displaced by external wind and traction.

[0030] 4. In the present invention, after the water-collecting diaphragm is assembled, the bonding plate on one side of the rotating seat can press the water-collecting diaphragm to further improve the assembly stability of the water-collecting diaphragm. The pressing plate can form a stepped sealing groove with the rubber ring through the inner sealing groove to improve the sealing effect of the water-collecting diaphragm and reduce the penetration of unfiltered water into the irrigation device. Moreover, through the designed filter cover, rainwater in the water-collecting diaphragm can be blocked by the filter cover and partially precipitate waste debris before overflowing from the top of the filter cover to the leakage cover, thereby improving the clarification and filtration effect of the collected liquid.

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.

[0045] See also Figure 1-Figure 11 The present invention provides a technical solution: a rainwater collection and infiltration irrigation device for fruit trees, comprising an irrigator 1, a water-collecting ground film 6 is arranged outside the irrigator 1, a pressing mechanism 3 is arranged on the top of the irrigator 1, and the water-collecting ground film 6 is nested in the pressing mechanism 3, the inner side of the pressing mechanism 3 is connected to a limited position seat 7, and the inner cavity of the limited position seat 7 is detachably connected to an infiltration irrigation control mechanism 2, and the infiltration irrigation rainfall is controlled by the infiltration irrigation control mechanism 2;

[0046] The bottom of the irrigation device 1 is connected to a root expansion mechanism 4, which includes a base 401. A plurality of infiltration tubes 403 are arranged around the base 401 to guide the infiltration direction. The infiltration control mechanism 2 includes a leakage cover 201. The leakage cover 201 has an inner cavity, and a plurality of infiltration holes 202 are arranged around the bottom of the inner cavity of the leakage cover 201 along the axis. The leakage cover 201 is detachably connected to the limit seat 7. A sliding hole 202 is provided at the center of the inner cavity of the leakage cover 201. The rod body 202 is slidably connected in the sliding hole, and a moving part 208 is connected to the top of the rod body, a fixed block 206 is connected to the bottom of the rod body, a plurality of sealing plates 210 are connected around the outer periphery of the fixed block 206, a filling block 211 is connected to the top of the sealing plate 210, and the filling block 211 is driven by pulling the moving part 208 to close the seepage hole 202, and a first spring 207 is sleeved on the outside of the rod body, and both ends of the first spring 207 are respectively connected to the moving part 208 and the bottom side of the inner cavity of the leakage cover 201.

[0047] Specifically, after a plurality of infiltrators 1 are placed around the fruit trees and covered with a water-collecting ground film 6 through the designed infiltrator 1, rainwater on the surface of the water-collecting ground film 6 can flow to the infiltrator 1 at a low position. When rainwater spreads to the inside of the leakage cover 201, rainwater can flow into the inside of the infiltrator 1 through the infiltration hole 202, and infiltrate to the outside through the holes on the outer side of the infiltrator 1. When the amount of rainwater increases and the fruit trees meet the need for infiltration irrigation, the cover plate 217 can be opened. At this time, the handle 209 is pressed downward to separate from the abutment block 216 in the sleeve, and then the infiltration can be stopped. The handle 209 is rotated so that the upward travel of the handle 209 is not limited by the abutment block 216. At this time, the compressed first spring 207 can use its own elastic force to drive the moving part 208 to move upward. The movement of the moving part 208 can drive the sealing plate 210 and the filling block 211 to move upward. The movement of the filling block 211 can close the seepage hole 202. The closing control of the rainwater infiltration channel in the leakage cover 201 is realized by the slidable filling block 211, which is conducive to closing the irrigation device 1 in the rainy season, reducing the gathering of rainwater to the fruit trees, and improving the adaptability of infiltration irrigation.

[0048] Furthermore, when the seepage hole 202 needs to be opened, the handle 209 can be pressed downward to move to the bottom side of the abutment block 216, and then the handle 209 can be rotated to correspond to the abutment blocks 216 on both sides, so that the abutment blocks 216 can limit the reset of the handle 209, so that the bottom seepage hole 202 is always in an open state;

[0049] Furthermore, the closing plate can fully close the seepage hole 202, and through the guide cover 212 designed at the bottom, the guide cover 212 can guide rainwater to be evenly distributed in the irrigation device 1 through the cone-shaped expansion, thereby improving the infiltration effect;

[0050] At the same time, the leakage cover 201 can be inserted into the seat 205 inside the limit seat 7 through the peripheral clamping block 204, which is conducive to removing and cleaning the leaf dust gathered outside the filter cover 5 by disassembling the leakage cover 201, and is convenient for maintenance.

The leakage hole on the top of the cover plate 217 is rotated to the top of different accommodating cavities by rotating the cover plate 217, so that the contact mode between the water and different accommodating cavities can be adjusted, which is convenient for adjusting to the flow channel of another accommodating cavity without nutrient filler 214 after sufficient fertilization, and convenient for switching irrigation modes. In particular, an infiltration groove 215 is opened through the top of the nutrient filler 214.

[0056] Furthermore, the designed sealing strip 203 can seal the gap between the liquid leakage cover 201 and the irrigation device 1 , which is beneficial to improving the assembly stability of the liquid leakage cover 201 .
