Description

Technical Field

[0001] The invention relates to the technical field of water-saving irrigation, in particular to an agricultural water-saving irrigation device. Background Art

[0002] Agriculture is a major water user. Flooding is a common traditional irrigation method. However, flooding consumes a lot of water. With the global population growth and economic development, the demand for water resources continues to increase, while the total amount of water resources is limited, resulting in a relative decrease in available water resources for agriculture. In many arid and semi-arid areas, water scarcity has become an important factor restricting agricultural development. Efficient water-saving irrigation technologies and equipment are urgently needed to alleviate water resource pressure and improve water resource utilization efficiency.

[0003] The traditional way of adding pesticides to water-saving irrigation is to dilute the pesticides and add them to the pool or tank of the sprinkler system, and then use a negative pressure pump to pump the water mixed with the medicine to the crop field. However, there is usually more water in the pool or tank, and it is difficult to mix the pesticides fully after adding them, resulting in uneven local pesticide concentrations. Some pesticides will precipitate or stratify in the water after being placed for a long time. Areas with high concentrations will cause pesticide damage to crops, and areas with low concentrations cannot effectively prevent and control pests and diseases, resulting in poor pesticide control effects during irrigation.

[0004] Therefore, we propose an agricultural water-saving irrigation device to solve the above-mentioned problems. Summary of the invention

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. When in use, when the irrigation water flow passes through the water supply pipe, the water flow will drive the turbine to rotate, and at the same time, the medicine replenishing wheel will rotate. When the surface of the medicine replenishing wheel adhering to the pesticide is turned into the drip irrigation pipe, the irrigation water flowing through the drip irrigation pipe will wash away the pesticide on the surface of the medicine replenishing wheel. Then, the water flowing into the drip irrigation pipe is mixed with the pesticide. The pesticide can be replenished as needed, avoiding the precipitation of the medicine in the pool, preventing the uneven application of the medicine to cause poor growth of crops.

[0018] 2. When in use, by starting the water pump to pressurize and pump water, when there is no rainwater collected in the rain storage tank, under the elastic action of a plurality of elastic ropes, the rain pumping pipe will be pulled into the inside of the limit ring, so that it is inserted inside the limit ring, and the water pump directly pumps the water in the irrigation pool. When rainwater is stored in the rain storage tank, under the action of two floating blocks, the communicating pipe will pull the rain pumping pipe out of the inside of the limit ring. Under the pressurization of the water pump, while pumping the water in the suction pool, the rainwater collected in the rain storage tank will also be pumped into the drip irrigation pipe for irrigating the farmland, playing a role in saving water.

[0019] 3. When in use, the rain-proof cover covers the rain collection hopper, which can prevent sundries such as fallen leaves and soil from entering the rain collection hopper. Through the rain drop sensor, the density of the rain drops can be sensed, and the forward and reverse motor is started to drive the driving gear to rotate by its output shaft. Under the meshing action of the driving gear and the driven gear, the driven gear drives the mounting shaft to rotate inside the mounting hole. Therefore, the rain-proof cover can be unfolded, and the rainwater falling into the rain collection hopper is collected into the inside of the rain storage tank and can be used for irrigating crops. At this time, the unfolded rain-proof cover is in an inclined state, and the rainwater will flow down along the inner wall of the rain-proof cover into the rain collection hopper. It has the advantage of increasing the rainwater collection area. The protective net can block sundries such as fallen leaves mixed in the rainwater and also facilitate the centralized treatment of sundries such as fallen leaves. Description of the Drawings

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment 1: Refer to Figure 1 - Figure 11As shown in the figure, the present invention provides a technical solution: an agricultural water-saving irrigation device, including a rain storage component 1, a drip irrigation component 3 and a medicine delivery component 4. The drip irrigation component 3 drips irrigation water into the crop fields, and when passing through the medicine delivery component 4, it drips the medicine solution into the crop fields. The drip irrigation component 3 includes a dredging cavity 311. One side of the dredging cavity 311 is fixedly communicated with a drip irrigation pipe 312. The bottom of the drip irrigation pipe 312 is provided with a first card slot 304 and a communication hole 305; the medicine delivery component 4 includes a medicine replenishing pipe 402, and the interior of the medicine replenishing pipe 402 is used for storing agricultural medicine solution. The bottom of the medicine replenishing pipe 402 is fixedly connected with a water supply pipe 401. The top of the medicine replenishing pipe 402 is provided with a second card slot 410. Both sides of the medicine replenishing pipe 402 and both sides of the water supply pipe 401 are provided with sealing rotation holes 411. The inner wall of each sealing rotation hole 411 is rotatably connected with a sealing shaft 407. A medicine replenishing wheel 409 is fixedly connected between the relative positions of two of the sealing shafts 407, and a turbine 408 is fixedly connected between the relative positions of the other two sealing shafts 407. The outer surfaces of the two sealing shafts 407 on the same side are both fixedly connected with runner wheels 406. A connecting belt 405 is movably connected between the outer surfaces of the two runner wheels 406. The outer surface of the medicine replenishing wheel 409 fits with the inner walls of the first card slot 304 and the second card slot 410. One end of the water supply pipe 401 is fixedly communicated with the bottom end of the communication hole 305, and the other end of the water supply pipe 401 is fixedly communicated with one side of the dredging cavity 311. The outer surface of the medicine replenishing pipe 402 is fixedly communicated with a medicine delivery port 403. One end of the medicine delivery port 403 is covered with a sealing cover 404. The drip irrigation component 3 further includes a water pump 301. The input end of the water pump 301 is fixedly communicated with an installation pipe 302. The output end of the water pump 301 is fixedly communicated with a receiving pipe 303. One end of the receiving pipe 303 fixedly penetrates into the interior of the dredging cavity 311. The bottom of the drip irrigation pipe 312 is fixedly communicated with a plurality of drip water heads 306. The outer surface of the drip irrigation pipe 312 is fixedly connected with a plurality of installation rings 307. The bottoms of the plurality of installation rings 307 are all fixedly connected with support rods 308. One end of each support rod 308 is welded with a limiting ring 309. The bottom of each limiting ring 309 is welded with a plurality of ground nails 310.

[0035] In this embodiment, when in use, the water pumped out under pressure by the water pump 301 first reaches the inside of the dredging chamber 311 through the receiving pipe 303. Since both the drip irrigation pipe 312 and the water supply pipe 401 are connected to the dredging chamber 311, the water inside the dredging chamber 311 will be diverted into the drip irrigation pipe 312 and the water supply pipe 401. Before irrigation, it is necessary to open the sealing cover 404 and inject liquid pesticide into the medicine supplement pipe 402 through the medicine delivery port 403. When the irrigation water flows through the water supply pipe 401, the water flow will drive the turbine 408 to rotate, thereby driving the rotating wheel 406 located below to rotate. Through the connection of the connecting belt 405, the rotating wheel 406 located above is rotated, and then the medicine supplement wheel 409 is rotated. The medicine supplement wheel 409 is located between the first card slot 304 and the second card slot 410. Therefore, when the medicine supplement wheel 409 rotates, the pesticide inside the medicine supplement pipe 402 adheres to its surface. When the surface with the adhered pesticide is turned into the drip irrigation pipe 312, the irrigation water flowing through the drip irrigation pipe 312 will wash away the pesticide on the surface of the medicine supplement wheel 409. Then the water flowing into the drip irrigation pipe 312 is mixed with the pesticide. The pesticide can be replenished as needed, avoiding the precipitation of the medicine in the pool, and preventing the poor growth of crops due to uneven application of the medicine. The irrigation water mixed with the pesticide flows inside the drip irrigation pipe 312 and is drip-irrigated at the root parts of the crops from each drip head 306. When installing this irrigation device, it is necessary to firmly insert the positioning rod 102 into the soil to ensure the stability of the rain storage tank 101, and then firmly insert the ground nail 310 into the soil to support the drip irrigation pipe 312. In addition, installing the sealing shaft 407 inside the sealing rotating hole 411 can prevent the leakage of the liquid inside the medicine supplement pipe 402 and the water supply pipe 401.

[0036] Embodiment Two: Figure 1 - Figure 11As shown in the figure, the rain storage component 1 includes a rain storage tank 101. A discharge pipe 104 is fixedly connected and communicated near the bottom of the front surface of the rain storage tank 101. A reinforcement port 105 is fixedly embedded on the outer surface of one side of the rain storage tank 101. A water pumping pipe 108 is fixedly connected to the inner wall of the reinforcement port 105. A plurality of positioning rods 102 are welded to the bottom of the rain storage tank 101. A limiting block 103 is welded to the outer surface of each positioning rod 102. An installation port 107 is fixedly embedded on the outer surface of the other side of the rain storage tank 101. The inner wall of the installation port 107 is fixedly connected to the outer surface of the installation pipe 302. One end of the water pumping pipe 108 is fixedly connected and communicated with a fixed hose 110. One end of the installation pipe 302 is fixedly connected and communicated with a connecting hose 106. A communicating pipe 111 is fixedly connected and communicated between one end of the fixed hose 110 and one end of the connecting hose 106. Reinforcing rods 112 are fixedly connected to the outer surfaces on both sides of the communicating pipe 111. Floating blocks 113 are fixedly connected to one ends of the two reinforcing rods 112. A rain pumping pipe 115 is fixedly connected and communicated with the bottom of the communicating pipe 111. A connecting ring 114 is fixedly connected to the outer surface of the rain pumping pipe 115. A plurality of elastic ropes 109 are fixedly connected to the bottom of the connecting ring 114. A limiting ring 116 is fixedly connected between one ends of the plurality of elastic ropes 109. The limiting ring 116 is fixedly installed on the inner bottom surface of the rain storage tank 101. The rain pumping pipe 115 is inserted into the inside of the limiting ring 116.

[0037] In this embodiment, during use, by starting the water pump 301 to pressurize and pump water, when there is no rainwater collected inside the rain storage tank 101, under the elastic action of the plurality of elastic ropes 109, the rain pumping pipe 115 will be pulled into the inside of the limiting ring 116 so that it is inserted into the inside of the limiting ring 116. The water pump 301 directly pumps the water in the irrigation pool. The water in the irrigation pool is pumped out through the water pumping pipe 108, the fixed hose 110, the communicating pipe 111, the connecting hose 106, and the installation pipe 302. Under the pressurization action, the irrigating water is conveyed into the drip irrigation pipe 312. When rainwater is stored inside the rain storage tank 101, under the action of the two floating blocks 113, the communicating pipe 111 will pull the rain pumping pipe 115 out of the inside of the limiting ring 116. Under the pressurization of the water pump 301, while pumping the water in the suction pool, the rainwater collected inside the rain storage tank 101 will also be pumped into the drip irrigation pipe 312 for irrigating farmland, playing a role in saving water.

[0038] Embodiment Three: Figure 1 - Figure 11As shown in the figure, a rain collection component 2 is provided at the top of the rain storage tank 101. The rain collection component 2 includes a rain collection hopper 201. A protective net 210 is clamped near the top of the inner wall of the rain collection hopper 201. An activity slot 206 is opened at the top of one side of the rain collection hopper 201. Mounting holes 205 are opened on the opposite inner walls of the activity slot 206. Mounting shafts 204 are rotatably connected to the inner walls of the two mounting holes 205. A rainproof cover 202 is fixedly connected between the opposite ends of the two mounting shafts 204. A rain drop sensor 203 is arranged on the top of the rainproof cover 202. One end of one of the mounting shafts 204 is fixedly connected with a driven gear 209. A positive and negative motor 207 is arranged on the outer surface of the rain collection hopper 201. The output shaft of the positive and negative motor 207 is fixedly connected with a driving gear 208. The outer surface of the driving gear 208 is meshed with the outer surface of the driven gear 209. The rain storage component 1 includes a rain storage tank 101. A discharge pipe 104 is fixedly communicated near the bottom of the front surface of the rain storage tank 101.

[0039] In this embodiment, when in use, the rainproof cover 202 covers the rain collection hopper 201, which can prevent sundries such as fallen leaves and soil from entering the rain collection hopper 201. When it starts to rain in the sky, the density of the rain drops can be sensed through the rain drop sensor 203. When the rain drops fall densely, the rain drop sensor 203 sends a signal to the external control system. Next, the positive and negative motor 207 receives the start signal, and its output shaft rotates, driving the driving gear 208 to rotate. Under the meshing action of the driving gear 208 and the driven gear 209, the driven gear 209 drives the mounting shaft 204 to rotate inside the mounting hole 205. Therefore, the rainproof cover 202 can be unfolded. The rain water falling into the rain collection hopper 201 is collected into the rain storage tank 101 and can be used for irrigating crops. At this time, the unfolded rainproof cover 202 is in an inclined state, and the rain water will flow down along the inner wall of the rainproof cover 202 into the rain collection hopper 201, which has the advantage of increasing the rain water collection area. The protective net 210 can block sundries such as fallen leaves mixed in the rain water and also facilitate the centralized treatment of sundries such as fallen leaves.

[0040] The use method and working principle of the device are as follows: when in use, the rain cover 202 is covered on the rain collecting bucket 201 to prevent fallen leaves, soil and other debris from entering the rain collecting bucket 201. When it starts to rain, the density of raindrops can be sensed by the raindrop sensor 203. When the raindrops fall densely, the raindrop sensor 203 sends a signal to the external control system. Next, the forward and reverse motor 207 receives the start signal, and its output shaft rotates, which drives the driving gear 208 to rotate. Under the meshing action of the driving gear 208 and the driven gear 209, the driven gear 209 drives the mounting shaft 204 to rotate inside the mounting hole 205, so that the rain cover 202 can be unfolded, and the rainwater falling into the rain collecting bucket 201 is collected in the rain storage tank 101. The inside of the rain tank 101 can be used to irrigate crops. At this time, the unfolded rain cover 202 is in a tilted state, and rainwater will flow down along the inner wall of the rain cover 202 to the inside of the rain collecting bucket 201. The protective net 210 can block the fallen leaves and other debris mixed in the rainwater. When in use, by starting the water pump 301 to pressurize and pump water, when the inside of the rain storage tank 101 does not collect rainwater, under the elastic action of multiple elastic ropes 109, the rain pumping pipe 115 will be pulled into the inside of the limiting ring 116 so that it is inserted into the inside of the limiting ring 116, and the water pump 301 directly draws water from the irrigation pool. The water in the irrigation pool is pumped out through the pumping pipe 108, the fixed hose 110, the connecting pipe 111, the connecting hose 106, and the installation pipe 302. Under the action of pressure , the irrigation water is transported to the drip irrigation pipe 312. When rainwater is stored in the rain storage tank 101, the connecting pipe 111 will be pulled out from the limiting ring 116 with the rain extraction pipe 115 under the action of the two floating blocks 113. Under the pressure of the water pump 301, while pumping water in the water pool, the rainwater collected in the rain storage tank 101 will be pumped into the drip irrigation pipe 312 for irrigating farmland. When in use, the water pumped out by the water pump 301 will first reach the inside of the dredging chamber 311 through the receiving pipe 303. Since the drip irrigation pipe 312 and the water supply pipe 401 are both connected to the dredging chamber 311, the water in the dredging chamber 311 will be diverted into the drip irrigation pipe 312 and the water supply pipe 401. Before irrigation, the sealing cover 40 needs to be opened. 4. Liquid pesticide is injected into the medicine supplementing tube 402 through the medicine delivery port 403. When the irrigation water flows through the water supply pipe 401, the water flow drives the turbine 408 to rotate, thereby driving the rotating wheel 406 located below to rotate. Through the connection of the connecting belt 405, the rotating wheel 406 located above rotates, and then the medicine supplementing wheel 409 rotates. The medicine supplementing wheel 409 is located between the first card slot 304 and the second card slot 410. Therefore, when the medicine supplementing wheel 409 rotates, the pesticide inside the medicine supplementing tube 402 adheres to its surface. When the surface adhered with the pesticide is transferred to the inside of the drip irrigation pipe 312, the irrigation water flowing through the drip irrigation pipe 312 will wash away the pesticide on the surface of the medicine supplementing wheel 409, so the water flowing into the drip irrigation pipe 312 is mixed with the pesticide.The pesticide can be replenished as needed. The irrigation water mixed with the pesticide flows inside the drip irrigation pipe 312 and is drip-irrigated at the root parts of the crops from each drip head 306. When installing this irrigation device, the positioning rod 102 needs to be firmly inserted into the soil to ensure the stability of the rain storage tank 101, and then the ground nail 310 is firmly inserted into the soil to support the drip irrigation pipe 312.

[0041] The wiring diagrams of the rain drop sensor 203, the forward and reverse motor 207 and the water pump 301 in the present invention belong to the common knowledge in the art. Their working principles are already known technologies, and their models are selected according to actual use. Therefore, the control methods and wiring arrangements of the rain drop sensor 203, the forward and reverse motor 207 and the water pump 301 will not be explained in detail.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
