Description

Technical Field

[0001] The present invention relates to the technical field of irrigation equipment, and particularly relates to a plant root irrigation device. Background Art

[0002] Irrigation refers to watering the land, mainly including methods such as flood irrigation, sprinkler irrigation, micro-sprinkler irrigation, drip irrigation, subsurface irrigation, regulated deficit irrigation, etc., and is divided into types such as pre-sowing irrigation, seedling-promoting irrigation, growth-stage irrigation, and winter irrigation. The irrigation principle is that the irrigation amount, irrigation frequency, and time should be determined according to the water requirements of plants, growth stages, climate, and soil conditions, and it is necessary to irrigate in a timely and appropriate manner and rationally.

[0003] However, when irrigating plants, generally the ground surface is irrigated. It takes a long time for the water to completely seep into the ground, and the water will also evaporate and spread to the surroundings, resulting in waste of water sources.

[0021] Compared with the prior art, the present invention has the following beneficial technical effects:

[0022] In the present invention, first, the height of the overflow water is adjusted by the adjusting mechanism. When irrigating, the water pump pumps out water and conveys it into the connecting pipe through the water inlet pipe, and then sends it into the irrigation bucket through the connecting pipe. The water flows into the ground through the irrigation holes, enabling irrigation of the ground. When too much water flows in, to prevent the water from flowing to surrounding positions, the excess water is filtered by the filter cylinder and then flows into the water collecting bucket, and then flows into the connecting pipe through the drain pipe and into the return water pipe, and flows back to the reservoir through the return water pipe, thereby avoiding waste of water resources and enabling the water to continuously irrigate the roots of plants at the installed position.

[0023] When it rains, the water will gather into the irrigation bucket through the conical groove. When the water level rises, after being filtered by the filter cylinder, it will overflow the adjusting mechanism, causing the water level to flow into the water collecting assembly, and realizing the reflux through the water collecting assembly to automatically collect the excess rainwater. When needed, water supply can be directly carried out through the reservoir.

[0024] When the filter cylinder is filtering, if not cleaned, it is easy for dirt to adhere to the filter cylinder, resulting in blockage of the filter cylinder and preventing water from overflowing. Therefore, when the water level changes, it will drive the cleaning mechanism to operate, cleaning the inner wall and bottom of the filter cylinder, thereby ensuring the smoothness of the filter cylinder and enabling it to normally recycle the excess water back to the reservoir.

[0040] Furthermore, the present invention is described in detail with reference to schematic diagrams. When detailing the embodiments of the present invention, for the convenience of explanation, the cross-sectional views showing the device structure will be enlarged locally out of the general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0041] Embodiment 1

[0042] As Figures 1-10 shown, a plant root irrigation device proposed by the present invention includes an upper and lower water unit 1, an irrigation assembly 2, a water collection assembly 3, a filter cartridge 6, an adjustment mechanism 7, and a cleaning unit.

[0043] The upper and lower water unit 1 includes a water inlet pipe 101, a water return pipe 102, and a plurality of connecting pipes 103; the irrigation assembly 2 is communicated with the water inlet pipe 101 through the connecting pipe 103; the water collection assembly 3 is arranged in the irrigation assembly 2 and is communicated with the water return pipe 102 through the connecting pipe 103; the filter cartridge 6 is arranged on the water collection assembly 3, and the lower end protrudes from the water collection assembly 3 and is located in the irrigation assembly 2; the adjustment mechanism 7 is arranged in the water collection assembly 3 and is arranged on the filter cartridge 6; the cleaning unit is arranged in the filter cartridge 6.

[0044] Both the water inlet pipe 101 and the water return pipe 102 are provided with a communication port and a connection mechanism 4; the connection mechanism 4 includes a connection sleeve 401 provided on the water inlet pipe 101 and the water return pipe 102 at the communication port and communicating with the connection pipe 103, a connection sleeve 402 with one end rotatably provided on the connection sleeve 401 and the other end snap-connected to the connection sleeve 401, and a locking assembly 403 provided on the connection sleeve 401 and the connection sleeve 402 for snap-connecting with each other; a communication port is drilled on the water inlet pipe 101 and the water return pipe 102, the connection sleeve 401 is moved to the communication port, and at this time the locking assembly 403 is in a loosened state, the connection sleeve 401 is aligned with the communication hole, and a sealing gasket is placed on the connection sleeve 401, the connection sleeve 402 is rotated so that the connection sleeve 402 cooperates with the connection sleeve 401 to wrap the water inlet pipe 101 or the water return pipe 102, and then the connection sleeve 402 is locked by the locking assembly 403, so that the connection sleeve 401 cooperates with the connection sleeve 402 to press the sealing gasket on the water inlet pipe 101 or the water return pipe 102, so that the connection mechanism 4 communicates with the water inlet pipe 101 or the water return pipe 102, so that water can flow into the irrigation assembly 2 through the connection pipe 103, or flow back into the water return pipe 102 through the connection pipe 103.

[0045] Among them, the irrigation assembly 2 includes an irrigation bucket 201, a water inlet 202 provided on the irrigation bucket 201 and connected to the connection pipe 103, a support base 203 provided at the lower end of the irrigation bucket 201 to lift the irrigation bucket 201, and an irrigation hole 204 provided at the bottom of the irrigation bucket 201 and outside the water collection assembly 3; the irrigation assembly 2 is used for collecting the water for irrigation and collecting rainwater.

[0046] Furthermore, the water collection assembly 3 includes a water collection bucket 301 provided inside the irrigation bucket 201, a cover plate 302 provided at the upper part of the water collection bucket 301 and having an opening, a mounting seat 303 provided at the lower end of the water collection bucket 301 and connected to the bottom and inner wall of the irrigation bucket 201, and a drain pipe 304 provided at the bottom of the water collection bucket 301 and passing through the irrigation bucket 201 and communicating with the connection pipe 103; a protection assembly 5 is slidably provided on the cover plate 302, and the water collection assembly 3 is used for collecting the water exceeding the water level, so that the water can overflow into the water collection assembly 3 and then flow into the water return pipe 102 through the water collection assembly 3.

[0047] During the deployment of this embodiment, the height of the return pipe 102 is lower than that of the water collection assembly 3, and the irrigation assembly 2 is buried underground, making the return pipe 102 also in a buried state. To facilitate rainwater collection, a conical groove should be built during deployment, with the upper part of the irrigation bucket 201 located at the lower part of the groove to facilitate water inflow into the irrigation assembly 2. A protective net should be placed above the irrigation assembly 2 to prevent leaves from falling into the irrigation assembly 2. The lower end of the irrigation assembly 2 supports the irrigation bucket 201 through the support base 203, separating the irrigation holes 204 from the bottom of the soil to avoid direct blockage. The end of the return pipe 102 is located in the reservoir, and the height of the end is lower than the lower part of the irrigation assembly 2, enabling water to flow into the reservoir without the need for additional power equipment.

[0048] During use, first adjust the height of the overflow through the adjustment mechanism 7. When irrigating, the water pump pumps water out and transports it through the inlet pipe 101 into the connecting pipe 103, and then into the irrigation bucket 201 through the connecting pipe 103. The water flows into the ground through the irrigation holes 204, capable of irrigating the ground. The inflow rate into the irrigation bucket 201 is much greater than the outflow rate of the irrigation bucket 201 and greater than the soil water absorption rate. Therefore, when too much water flows in, to prevent the water from flowing to surrounding areas, the excess water is filtered through the filter cylinder 6 and flows into the water collection bucket 301, then through the drain pipe 304 into the connecting pipe 103, and into the return pipe 102, flowing back into the reservoir through the return pipe 102, thus avoiding waste of water resources and enabling continuous irrigation of the plant roots at the installation location.

[0049] When it rains, the water will collect into the irrigation bucket 201 through the conical groove. When the water level rises, after being filtered through the filter cylinder 6, it will overflow the adjustment mechanism 7, causing the water level to flow into the water collection assembly 3, achieving reflux through the water collection assembly 3 and automatically collecting the excess rainwater. When needed, water supply can be directly carried out through the reservoir.

[0050] When the filter cylinder 6 is filtering, if not cleaned, it is easy for dirt to adhere to the filter cylinder 6, causing the filter cylinder 6 to be blocked and water unable to overflow. Therefore, when the water level changes, it will drive the cleaning mechanism to operate, cleaning the inner wall and bottom of the filter cylinder 6, thus ensuring the smoothness of the filter cylinder 6 and enabling it to normally recycle the excess water back into the reservoir. According to the species characteristics of the plants, arrange the corresponding number of this device, where the inlet pipes 101 are arranged separately according to the plant species, enabling unified irrigation of the same kind of plants, and the return pipe 102 can be shared.

[0051] Embodiment Two

[0052] Such as Figures 1-10As shown in the figure, a plant root irrigation device proposed by the present invention. Compared with the first embodiment, in this embodiment, the protection component 5 includes a conical cover 501 with an outer diameter larger than the opening and disposed above the cover plate 302, a guide rod 502 disposed on the conical cover 501 and slidably connected to the cover plate 302, and an exhaust rack 503 disposed at the opening of the cover plate 302 and capable of abutting against the conical cover 501.

[0053] In this embodiment, when the conical cover 501 is lifted upward to expose the opening, it is convenient to view the position of the pressing plate 702 when deploying the present invention, so that the height of the pressing plate 702 can be controlled according to the type of plant, which is convenient for adjustment. After the adjustment is completed, the conical cover 501 is lowered, so that the conical cover 501 falls onto the exhaust rack 503. The guide rod 502 guides the conical cover 501, and the exhaust rack 503 pads up the conical cover 501, so that the conical cover 501 can prevent dirt from falling into the water collecting bucket 301 through the opening while not affecting the gas flow in the water collecting bucket 301, so that no negative pressure is generated in the water collecting bucket 301. Thus, according to the principle of the communicating vessel, water can overflow into the water collecting component 3.

[0054] Embodiment Three

[0055] As Figures 1-10 As shown in the figure, a plant root irrigation device proposed by the present invention. Compared with the first embodiment or the second embodiment, in this embodiment, an installation cover 305 is provided at the bottom of the water collecting bucket 301; the filter cylinder 6 is disposed in the installation cover 305; the adjusting mechanism 7 includes a folding tube 701 disposed on the installation cover 305 and hermetically connected, a pressing plate 702 disposed on the folding tube 701, a lifting assembly 703 disposed on the cover plate 302 and slidably connected to the pressing plate 702, and a guide rail 704 rotatably disposed on the cover plate 302 and drivingly connected to the pressing plate 702.

[0056] In this embodiment, the installation cover 305 is used to install the filter cartridge 6, and can prevent sundries from directly adhering to the outer wall of the filter cartridge 6. At the same time, it allows water to enter only through the filter cartridge 6, and only when the water level moves upward and then passes through the filtration of the filter cartridge 6 can it enter the folding pipe 701. By rotating the guide rail 704, the guide rail 704 is a screw moving structure. By rotating the handle at the upper end of the guide rail 704, the screw is driven to rotate, so that the screw drives the pressing plate 702 to move. The lifting assembly 703 guides the pressing plate 702, and the pressing plate 702 drives the folding pipe 701 to move, thereby adjusting the position of the upper end of the pressing plate 702 and adjusting the position of the overflow water in the irrigation bucket 201. Thus, during irrigation, the amount of irrigation can be controlled, so that the excess water overflows above the pressing plate 702 and flows into the water collecting assembly 3, and then flows back to the reservoir through the return pipe 102. Therefore, the irrigation amount can be regulated according to the type of plants to avoid waste of water. When it rains, the overflow water can be collected and the water can flow back to the reservoir, and the water can be collected when it rains.

[0057] Embodiment 4

[0058] As Figures 1-10 shown, a plant root irrigation device proposed by the present invention. Compared with Embodiment 1, Embodiment 2, or Embodiment 3, in this embodiment, the cleaning unit includes a cleaning mechanism 8 rotatably arranged in the filter cartridge 6, a rotating mechanism 9 rotatably arranged in the filter cartridge 6 and slidably connected to the cleaning mechanism 8, and a support assembly 10 arranged on the filter cartridge 6 and slidably connected to the rotating mechanism 9; the support assembly 10 includes a support frame 1001 arranged on the filter cartridge 6, a sliding rod 1002 arranged on the support frame 1001, and a rotating seat 1003 arranged at the lower end of the sliding rod 1002.

[0059] Furthermore, the rotating mechanism 9 includes a rotating rod 901 rotatably arranged on the support frame 1001, the rotating seat 1003, and the filter cartridge 6, a threaded sleeve 902 threadedly connected to the rotating rod 901, and a floating block 903 arranged on the threaded sleeve 902 and slidably connected to the sliding rod 1002.

[0060] Among them, the rotating rod 901 includes a supporting part 9011, a threaded part 9012 arranged on the supporting part 9011 and threadedly connected to the threaded sleeve 902, a guiding part 9013 arranged at the lower part of the supporting part 9011 and slidably connected to the slider 802, and a connecting part 9014 arranged at the lower part of the guiding part 9013 and rotatably connected to the filter cartridge 6; the supporting part 9011 is used for support so that it can rotate on the supporting assembly 10, and the threaded part 9012 is threadedly connected to the threaded sleeve 902, so that when the threaded sleeve 902 moves, it can drive the threaded part 9012 to rotate. When the threaded part 9012 rotates, it drives the supporting part 9011 to rotate, and when the supporting part 9011 rotates, it drives the guiding part 9013 and the connecting part 9014 to rotate. The guiding part 9013 can drive the slider 802 to rotate, so as to drive the cleaning brush 801 to rotate; the guiding part 9013 can drive the slider 802 to rotate without affecting the sliding of the slider 802, so that the lower part of the cleaning brush 801 can be attached to the bottom of the filter cartridge 6, and pressure can be applied to better clean the bottom of the filter cartridge 6. The power of the threaded sleeve 902 comes from the self-weight of the floating block 903 and the buoyancy after water enters the filter cartridge 6. When there is water, affected by the buoyancy, the floating block 903 moves upward, driving the threaded sleeve 902 to move upward, so that the rotating rod 901 rotates; when the water is drained, it is affected by the gravity of the floating block 903 itself, so that it moves downward, so that the rotating rod 901 rotates in the reverse direction. When the rotating rod 901 rotates, the filter cartridge 6 can be cleaned, realizing cleaning the filter cartridge 6 once when the water level rises and once again when it drops, ensuring the smoothness of the filter cartridge 6 and avoiding blockage.

[0061] Furthermore, the cleaning mechanism 8 includes a cleaning brush 801 slidably arranged in the filter cartridge 6 and abutted against the bottom and inner wall of the filter cartridge 6, a slider 802 slidably arranged on the rotating rod 901 and slidably connected to the cleaning brush 801, a pushing sleeve 804 slidably arranged on the rotating rod 901, a connecting rod 803 with two ends respectively rotatably connected to the cleaning brush 801 and the pushing sleeve 804, and an elastic member 805 arranged on the rotating rod 901 and with its output end abutted against the pushing sleeve 804; the rotation of the rotating rod 901 drives the cleaning brush 801 to move, so that the L-shaped cleaning brush 801 can fit with the bottom and inner wall of the filter cartridge 6, sweeping the dirt adhered to the filter cartridge 6, so as to avoid the blockage of the filter cartridge 6 by dirt, making the water flow more smoothly when collecting water.

[0062] In this embodiment, the elastic member 805 is used to push the push sleeve 804 downward. The push sleeve 804 pushes the connecting rod 803 downward, and the connecting rod 803 pushes the cleaning brush 801 downward. The cleaning brush 801 drives the slider 802 downward, so that the lower part of the cleaning brush 801 is attached to the lower part of the filter cartridge 6. When the lower part of the cleaning brush 801 is completely connected to the filter cartridge 6, it can no longer move downward. At this time, the force generated by the downward movement of the push sleeve 804 will drive the cleaning brush 801 to move towards the inner wall of the filter cartridge 6 through the connecting rod 803, causing the cleaning brush 801 to slide on the slider 802, so that the side of the cleaning brush 801 contacts the inner wall of the filter cartridge 6. Thus, the L-shaped cleaning brush 801 can contact the inner wall and the bottom of the filter cartridge 6, and can clean the filter cartridge 6 when the cleaning brush 801 rotates, preventing the filter cartridge 6 from being blocked. Moreover, due to the thrust generated by the elastic member 805, the cleaning brush 801 can continuously fit with the filter cartridge 6. When a hard object blocks the cleaning brush 801, it can adaptively adjust elastically, so that it can knock the hard object away when hitting the hard object next time, or automatically bypass the hard object, preventing the cleaning brush 801 from being stuck.

[0063] It is installed on the filter cartridge 6 through the support frame 1001. The rotating seat 1003 and the floating block 903 are supported by the sliding rod 1002, so that the floating block 903 can only move along the sliding rod 1002. The support frame 1001 cooperates with the rotating seat 1003 to support the rotating rod 901, enabling the rotating rod 901 to rotate on the support assembly 10 and rotate more smoothly. When water enters the filter cartridge 6, it is affected by the buoyancy of the water. When the water level rises, it will push the floating block 903 to move. The floating block 903 drives the threaded sleeve 902 to move, thereby driving the rotating rod 901 to rotate through the thread, and then driving the cleaning mechanism 8 to rotate, so that the cleaning brush 801 can rotate inside the filter cartridge 6 to clean the inner wall and the bottom of the filter cartridge 6, preventing debris from adhering to and blocking the mesh holes of the filter cartridge 6 and ensuring the stability of the water flow.

[0064] When the water level gradually drops, due to the gravity of the floating block 903 itself, the floating block 903 moves downward following the water level. Thus, the floating block 903 drives the threaded sleeve 902 to move downward, causing the rotating rod 901 to rotate in the reverse direction, and then cleaning the inner wall of the filter cartridge 6 again, so as to perform secondary cleaning, so that after the water is discharged, it still remains in a clean and unblocked state, facilitating the entry of water into the filter cartridge 6 when the water level rises next time.

[0065] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those skilled in the art.
