Description

Technical Field

[0001] The present invention relates to the field of irrigation, and in particular to a water-saving irrigation device with a filtering function. Background Art

[0002] When irrigation is carried out in arid areas, when the water flows into the soil surface, part of the irrigation water will be lost due to evaporation. Most of the water pumps used for irrigation do not have a filtering mechanism, which can easily cause the water pump or irrigation nozzle to be blocked. Clearing the blockage requires operation time and increases unnecessary workload.

[0003] Furthermore, different crops require different amounts of irrigation water during their growth cycles. For example, rice requires the most water, with early rice requiring approximately 180-230 cubic meters per mu (approximately 180-230 cubic meters per mu) and late rice requiring up to 230-320 cubic meters per mu (approximately 300 cubic meters per mu) annually. Vegetables like Chinese cabbage and leeks require approximately 200-500 cubic meters per mu (approximately 200-500 cubic meters per mu) per crop. Therefore, when growing different varieties or crops with different growth cycles on the same plot of land, using the same irrigation system often limits the amount of water available.

DETAILED DESCRIPTION

[0019] In order to make those skilled in the art better understand the present invention, the present invention is further clearly and completely described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless there is a conflict, the features in the embodiments and examples of this application can be combined with each other.

[0020] A typical embodiment of the present invention provides a water-saving irrigation device with a filtering function, such as Figure 1 As shown, it includes a serial hose 6 and an irrigation filter mechanism 7 connected through the serial hose 6 , and the irrigation water is guided to different locations through the serial hose 6 .

[0021] Among them, such as Figure 6 As shown, the irrigation and filtering mechanism 7 includes a conduit 71 , and guide ports 711 are installed on both sides of the conduit 71 , and valves 712 are provided on the guide ports 711 .

[0022] An extension tube 72 is provided on the upper side of the conduit 71 , and the conduit 71 and the extension tube 72 are threadedly connected. A rubber gasket is provided at the connection between the conduit 71 and the extension tube 72 to increase the sealing performance of the conduit 71 and the extension tube 72 to prevent water from overflowing.

[0023] refer to Figure 9 、 Figure 12 and Figure 13 As shown in FIG. 7 , a protective chamber 7201 is mounted at the top of the extension tube 72. A top platform 7202 is provided on the top surface of the extension tube 72. A drive motor 7203 is mounted on the top platform 7202. The output end of the drive motor 7203 is connected to a drive gear 7204. A guide gear 7205 is connected to the side of the drive gear 7204. The drive gear 7204 and the guide gear 7205 are meshed. A drive screw 7206 is connected to the middle of the guide gear 7205. A screw thread connection structure is formed between the guide gear 7205 and the drive screw 7206.

[0024] like Figure 14 As shown, the bottom end of the driving screw 7206 is connected to a guide plate 7209 , a mounting frame 7210 is provided on the guide plate 7209 , and second filter plates 7211 are evenly distributed on the mounting frame 7210 .

[0025] like Figure 12 As shown, a top plate 7207 is installed at the top of the driving screw rod 7206, and a limiting rod 7208 is installed between the top plate 7207 and the guide plate 7209; the limiting rod 7208 and the top platform 7202 are a through-sliding connection structure, and the driving screw rod 7206 and the protective bin 7201 are a through-sliding connection.

[0026] When the driving gear 7204 rotates, it drives the guide gear 7205 to rotate. The thread in the middle of the guide gear 7205 engages with the driving screw 7206. The driving screw 7206 is limited by the limiting rod 7208. The driving screw 7206 moves in the vertical direction, driving the guide plate 7209 to move up and down. The mounting frame 7210 installed on the guide plate 7209 will also move up and down, thereby driving the second filter plate 7211 on the mounting frame 7210 to move in position. After the water source has been filtered for a certain period of time, the second filter plate 7211 that first comes into contact with the water is replaced by moving the position to ensure the effectiveness of the filtration.

[0027] like Figure 7 、 Figure 8 As shown, a water flow control mechanism 8 is provided at the lower side of the irrigation filter mechanism 7. The water flow control mechanism 8 includes an outer housing 81. A connecting pipe 82 is provided at the top end of the outer housing 81. The connecting pipe 82 is connected to the conduit 71. The connecting pipe 82 and the conduit 71 are detachable, allowing for flexible cleaning of the irrigation filter mechanism 7 and achieving efficient filtration of the irrigation filter mechanism 7.

[0028] refer to Figure 10 、 Figure 11 An inner cover tube 811 is provided in the outer cover tube 81 , an irrigation pipe 84 is provided between the inner cover tube 811 and the outer cover tube 81 , and irrigation holes 85 are distributed on the irrigation pipe 84 .

[0029] The outer cover tube 81 is provided with evenly spaced marking lines. The outer cover tube 81 and the inner cover tube 811 are designed as a whole. Irrigation holes 85 are evenly spaced on the irrigation tube 84. The distribution of irrigation holes 85 corresponds to the marking lines distributed on the outer cover tube 81. The outer cover tube 81 and the inner cover tube 811 are used to control the exposed area of ​​the irrigation tube 84. When the exposed area of ​​the irrigation tube 84 is small, the irrigation water flow is reduced. When the exposed area of ​​the irrigation tube 84 is large, the irrigation water flow is increased, which effectively achieves precise irrigation while reducing water evaporation. The marking lines are marked with different colors, and the removal position and the depth of the irrigation tube 84 can be directly determined by the marking lines.

[0030] An operating handle 83 is installed at the top end of the outer cover tube 81. During installation, the outer cover tube 81 is inserted into the ground to be irrigated through the operating handle 83.

[0031] A tip seat 88 is installed at the bottom end of the irrigation pipe 84, and a limiting block 89 is distributed on the tip seat 88. The tip seat 88 can send the water control mechanism 8 into the soil and effectively limit and fix the outer cover tube 81 through the limiting block 89.

[0032] like Figure 11 As shown, a baffle 86 is provided on the outer wall of the irrigation hole 85, and a check valve 87 is installed in the irrigation hole 85. The opening direction of the check valve 87 is toward the baffle 86. The baffle 86 blocks the external soil and also prevents the check valve 87 from being damaged.

[0033] In a preferred embodiment, a water pipe 4 is installed at the front end of the serial hose 6, and a mounting mechanism 5 and an irrigation pump 3 are provided on the water pipe 4. The water pipe 4 cooperates with the mounting mechanism 5 to be installed on the corresponding ground to locate the position of the irrigation pump 3.

[0034] like Figure 2 As shown, a water pump 1 is provided on the input end of the irrigation pump 3, and a water pumping filter mechanism 2 is installed on the water pump 1. Figure 3 As shown, the water pumping and filtering mechanism 2 includes a water pumping port 21 , an internal thread 22 , a first filter plate 23 , a mounting ring 24 , a pulling rope 25 and a pulling ring 26 , and the water pumping port 21 is fixedly connected to the water pumping pipe 1 .

[0035] Since the water source for irrigation is not fixed, there may be many impurities in the water source. The first filter plate 23 can perform pre-filtration during the pumping process, which can effectively protect the irrigation pump 3. The first filter plates 23 are arranged in multiple groups. Multiple groups of first filter plates 23 can achieve sufficient filtration of the water source.

[0036] An internal thread 22 is provided at the inner diameter of the water suction port 21, and the first filter plate 23 is connected through the internal thread 22. The first filter plate 23 and the internal thread 22 are threadedly connected, and the first filter plate 23 can be flexibly replaced or disassembled for cleaning.

[0037] A mounting ring 24 is installed on the side of the water pumping port 21 , a pulling rope 25 is connected inside the mounting ring 24 , and a pulling ring 26 is provided on the pulling rope 25 , which can drive the water pumping port 21 to swing.

[0038] In a preferred embodiment, Figure 4 and Figure 5 As shown, the installation mechanism 5 includes a sleeve 51, an extension piece 52, an insertion rod 53, a handle 54 and a pointed block seat 55. The sleeve 51 is arranged at the outer wall of the water pipe 4 and is nested and connected with it. Extension pieces 52 are installed at both ends of the sleeve 51, and an insertion rod 53 is arranged in the extension piece 52.

[0039] An installation slot 521 is provided in the extension piece 52, and the installation slot 521 and the insertion rod 53 form a nested connection. A positioning slot 522 is preset on the side of the installation slot 521, and a positioning block 523 is provided in the positioning slot 522. A pull handle 524 is installed on the positioning block 523; the positioning block 523 and the positioning slot 522 are snap-fitted.

[0040] An inclined block 531 is distributed on the insertion rod 53 . A first slot 532 is provided on the upper side of the inclined block 531 . A second slot 533 is preset on the lower side of the inclined block 531 . The second slot 533 is nested and engaged with the positioning block 523 .

[0041] A handle 54 is mounted at the top of the insertion rod 53, and a prong seat 55 is connected to the bottom of the insertion rod 53. A first clamping block 541 is mounted on the handle 54, which nests and engages with the first slot 532 at the top. A second clamping block 551 is mounted on the prong seat 55, which nests and engages with the second slot 533 at the bottom.

[0042] The insertion rod 53 is inserted into the mounting groove 521 within the extension piece 52, and the depth of insertion into the ground is adjusted according to the installation location, facilitating the positioning and installation of the water pipe 4 by the installation mechanism 5. The nested connection between the second clamping block 551 of the sharp block seat 55 and the second clamping groove 533 allows for flexible removal and installation of the sharp block seat 55. A sharp block seat 55 inserted directly into the ground cannot detect the soil environment and is easily damaged by rocks. Replacing the sharp block seat 55 ensures its sharpness. The first clamping block 541 of the pull handle 54 engages with the first clamping groove 532, allowing the pull handle 54 to be flexibly removed.

[0043] In another preferred embodiment, Figure 15 As shown, the mounting frame 7210 is evenly provided with telescopic chambers 7212. A spring 7213 is provided in the telescopic chamber 7212, and a limit push block 7214 is installed on the spring 7213. The spring 7213 drives the limit push block 7214 to expand and contract. When the second filter plate 7211 is installed, the pushing force of the second filter plate 7211 pushes the limit push block 7214 back into the telescopic chamber 7212, squeezing the spring 7213. After the second filter plate 7211 is installed, the spring 7213 on the limit push block 7214 returns to its original position and rebounds, pushing the limit push block 7214 out of the telescopic chamber 7212, supporting the second filter plate 7211 and facilitating the removal and installation of the second filter plate 7211.

[0044] In a preferred embodiment, Figure 9 、 Figure 12 As shown, a remote sensing module 73 is installed at the top of the extension tube 72, and a power module is provided at the remote sensing module 73. The power module is electrically connected to the drive motor 7203, and the drive motor 7203 is a servo motor. The remote sensing module 73 realizes remote sensing control under the control of the background control module to realize the operation of the drive motor 7203. After the equipment operation cycle reaches a certain time, the drive motor 7203 is started automatically or manually through the background control module. After the water volume control mechanism 8 is installed, the drive motor 7203 runs, thereby realizing the up and down movement of the drive screw 7206.

[0045] According to the embodiment provided by the present invention, when working, first install the water pipe 4, and install the water pipe 4 in an empty space next to the water source. Take out the sleeve 51 and put it on both ends of the water pipe 4, install the plug rod 53 according to the terrain of the installation site, install the first block 541 on the pull handle 54 on the first slot 532 for installation, and then install the second block 551 on the pointed block seat 55 in the second slot 533. Press the pull handle 54 to break the ground through the pointed block seat 55 and insert the plug rod 53 into the ground to complete the positioning of the water pipe 4. After installation, separate the first block 541 from the first slot 532, and take out the pull handle 54 to prevent irrelevant personnel from operating the plug rod 53 when not in operation.

[0046] Subsequently, the water volume regulating mechanism 8 is installed according to the irrigation location. During installation, the outer cover tube 81 is inserted into the irrigated ground through the operating handle 83. The pointed seat 88 at the bottom end of the irrigation pipe 84 makes it easier to insert the outer cover tube 81 into the soil. The connecting pipe 82 is connected to the conduit 71, and the irrigation filter mechanism 7 is installed. Subsequently, the serial hose 6 is installed on the guide ports 711 on both sides of the conduit 71. The valve 712 can be opened according to the irrigation area. The serial hose 6 is used to divert the water source to different locations.

[0047] According to the depth and amount of water for irrigating vegetation, the position between the outer cover tube 81 and the irrigation pipe 84 is adjusted, and the outer cover tube 81 is pulled upward using the operating handle 83, and the equally spaced marking lines set on the outer cover tube 81 will leave the ground.

[0048] Install the first filter plate 23, place the water inlet 21 and the water pumping pipe 1 into the water source, turn on the irrigation pump 3, and the water source enters the water pumping pipe 1 through the first filter plate 23. The water is pressurized by the irrigation pump 3 and directed to the water pipe 4. The water source is directed to each water control mechanism 8 one by one through the serial hose 6 on the water pipe 4 for irrigation. When the water source is extracted, the first filter plate 23 can perform preliminary filtration during pumping. The pre-filtration can effectively protect the irrigation pump 3.

[0049] Before the water source enters the water volume control mechanism 8, it will first pass through the irrigation filter mechanism 7, and the second filter plate 7211 will filter the water source again. After a period of filtration, the remote sensing module 73 controls the drive motor 7203 to start, and the drive gear 7204 on the output end of the drive motor 7203 rotates to drive the guide gear 7205 to rotate, so that the drive screw 7206 drives the guide plate 7209 to move, and then drives the second filter plate 7211 on the mounting frame 7210 to move in the conduit 71. After the water source has been filtered for a certain period of time, the second filter plate 7211 that first comes into contact with the water is replaced by the movement.

[0050] When replacing the second filter plate 7211 uniformly, separate the conduit 71 from the extension tube 72. When pushing the second filter plate 7211, the limiting push block 7214 squeezes the spring 7213 and retracts it into the telescopic chamber 7212, and the second filter plate 7211 is disassembled and installed. After the new second filter plate 7211 is installed, the spring 7213 returns to its original position to support and limit the second filter plate 7211.

[0051] The scope of protection claimed by the present invention is not limited to the above specific embodiments. For those skilled in the art, the present invention may have various variations and modifications. Any modifications, improvements and equivalent substitutions made within the concept and principle of the present invention should be included in the scope of protection of the present invention.
