Description

Technical Field

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

[0002] Irrigation refers to the use of water to irrigate the land, mainly including flood irrigation, sprinkler irrigation, micro-sprinkler irrigation, drip irrigation, infiltration irrigation, deficit irrigation, etc., which are divided into irrigation before sowing, irrigation for seedling promotion, irrigation during the growth period and irrigation in winter. The principle of irrigation is that the amount of irrigation, the number of irrigations and the time should be determined according to the water requirements of the plants, the growth stage, the climate and the soil conditions. Irrigation should be timely, appropriate and reasonable.

[0003] However, when irrigating plants, the surface is usually irrigated. It takes a long time for the water to completely penetrate into the ground, and the water will also evaporate and diffuse around, thus wasting water resources. When it rains, the collected water cannot be collected. Summary of the invention

[0004] The purpose of the present invention is to address the problems existing in the background technology and to propose a plant root irrigation device that can collect rainwater when it rains and return excess water to a reservoir during irrigation to avoid waste.

[0006] Preferably, the water inlet pipe and the water return pipe are both provided with a connecting port and a connecting mechanism; the connecting mechanism includes a connecting sleeve arranged on the water inlet pipe and the water return pipe and located at the connecting port and connected to the connecting pipe, a connecting sleeve with one end rotatably arranged on the connecting sleeve and the other end clamped with the connecting sleeve, and a locking assembly arranged on the connecting sleeve and the connecting sleeve for mutual clamping.

[0007] Preferably, the irrigation assembly comprises an irrigation bucket, a water inlet arranged on the irrigation bucket and connected to the connecting pipe, a support seat arranged at the lower end of the irrigation bucket to raise the irrigation bucket, and an irrigation hole arranged at the bottom of the irrigation bucket and located on the outside of the water collection assembly.

[0008] Preferably, the water collecting assembly comprises a water collecting barrel arranged inside the irrigation barrel, a cover plate arranged on the upper part of the water collecting barrel and having an opening, a mounting seat arranged at the lower end of the water collecting barrel and connected to the bottom and inner wall of the irrigation barrel, and a drainage pipe arranged at the bottom of the water collecting barrel, passing through the irrigation barrel and connected to the connecting pipe; a protective assembly is slidably arranged on the cover plate.

[0009] Preferably, the protective assembly includes a conical cover having an outer diameter larger than the opening and disposed above the cover plate, a guide rod disposed on the conical cover and slidably connected to the cover plate, and an exhaust frame disposed at the opening of the cover plate and capable of abutting against the conical cover.

[0010] Preferably, a mounting cover is provided at the bottom of the water collecting barrel; the filter cartridge is arranged in the mounting cover; the adjusting mechanism includes a folding tube arranged on the mounting cover and sealedly connected, a pressure plate arranged on the folding tube, a lifting assembly arranged on the cover plate and slidably connected to the pressure plate, and a guide rail rotatably arranged on the cover plate and drivingly connected to the pressure plate.

[0012] Preferably, the rotating mechanism comprises a rotating rod rotatably arranged on the support frame, the rotating seat, and the filter cartridge, a threaded sleeve threadedly connected to the rotating rod, and a floating block arranged on the threaded sleeve and slidably connected to the sliding rod.

[0013] Preferably, the cleaning mechanism includes a cleaning brush slidably arranged in the filter cartridge and abutting against the bottom and inner wall of the filter cartridge, a sliding block slidably arranged on the rotating rod and slidably connected to the cleaning brush, a pushing sleeve slidably arranged on the rotating rod, a connecting rod whose two ends are rotatably connected to the cleaning brush and the pushing sleeve respectively, and an elastic member arranged on the rotating rod and whose output end abuts against the pushing sleeve.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects: In the present invention, the height of the overflow is first adjusted by the adjusting mechanism. When irrigation is carried out, the water pump draws out water and transports the water to the connecting pipe through the water inlet pipe, and then transports the water to the irrigation bucket through the connecting pipe. The water flows into the ground through the irrigation hole, and can irrigate the ground. When too much water flows in, in order to prevent the water from flowing to the surrounding position, the excess water is filtered by the filter cartridge and then flows into the water collection bucket, and then flows into the connecting pipe through the drainage pipe, and flows into the return pipe, and flows back to the water storage tank through the return pipe, thereby avoiding the waste of water resources and allowing the water to continuously irrigate the roots of plants at the installation position.

[0016] When it rains, water will gather into the irrigation barrel through the conical groove. When the water level rises, it will be filtered through the filter cartridge and then overflow the regulating mechanism, causing the water to flow into the water collection component. The water collection component will then reflux and automatically collect excess rainwater. When needed, it can be directly supplied through the reservoir.

[0017] When the filter cartridge is filtering, if it is not cleaned, dirt will easily adhere to the filter cartridge, causing the filter cartridge to be blocked and water to be unable to overflow. Therefore, when the water level changes, it will drive the cleaning mechanism to operate and clean the inner wall and bottom of the filter cartridge, thereby ensuring the smooth flow of the filter cartridge and enabling it to normally recycle excess water into the reservoir.

DETAILED DESCRIPTION

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments, either individually or selectively.

[0024] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0025] Embodiment 1 like Figure 1-10 As shown, a plant root irrigation device proposed by the present invention includes a water up and down unit 1, an irrigation component 2, a water collection component 3, a filter cartridge 6, an adjustment mechanism 7, and a cleaning unit; The upper and lower water units 1 include a water inlet pipe 101, a water return pipe 102, and a plurality of connecting pipes 103; the irrigation component 2 is connected to the water inlet pipe 101 through the connecting pipe 103; the water collecting component 3 is arranged in the irrigation component 2, and is connected to the water return pipe 102 through the connecting pipe 103; the filter cartridge 6 is arranged on the water collecting component 3, and the lower end of the water collecting component 3 protrudes and is located in the irrigation component 2; the adjusting mechanism 7 is arranged in the water collecting component 3 and on the filter cartridge 6; the cleaning unit is arranged in the filter cartridge 6.

[0026] The water inlet pipe 101 and the water return pipe 102 are both provided with a connecting port and a connecting mechanism 4; the connecting mechanism 4 comprises a connecting sleeve 401 provided on the water inlet pipe 101 and the water return pipe 102 and located at the connecting port and connected to the connecting pipe 103, a connecting sleeve 402 with one end rotatably provided on the connecting sleeve 401 and the other end engaged with the connecting sleeve 401, and a locking assembly 403 provided on the connecting sleeve 401 and the connecting sleeve 402 for mutual engagement; a connecting port is made on the water inlet pipe 101 and the water return pipe 102, the connecting sleeve 401 is moved to the connecting port, and the locking assembly 403 is in a loosened state at this time. In this state, align the connecting sleeve 401 with the connecting hole, place a sealing gasket on the connecting sleeve 401, rotate the connecting sleeve 402 so that the connecting sleeve 402 cooperates with the connecting sleeve 401 to wrap the water inlet pipe 101 or the water return pipe 102, and then lock the connecting sleeve 402 through the locking assembly 403, so that the connecting sleeve 401 cooperates with the connecting sleeve 402 to press the sealing gasket on the water inlet pipe 101 or the water return pipe 102, so that the connecting mechanism 4 is connected with the water inlet pipe 101 or the water return pipe 102, so that water can flow into the irrigation assembly 2 through the connecting pipe 103, or flow back into the water return pipe 102 through the connecting pipe 103.

[0027] The irrigation assembly 2 includes an irrigation bucket 201, a water inlet 202 arranged on the irrigation bucket 201 and connected to the connecting pipe 103, a support seat 203 arranged at the lower end of the irrigation bucket 201 to raise the irrigation bucket 201, and an irrigation hole 204 arranged at the bottom of the irrigation bucket 201 and located on the outside of the water collection assembly 3; the irrigation assembly 2 is used to collect irrigation water and rainwater.

[0028] Furthermore, the water collecting assembly 3 includes a water collecting barrel 301 arranged inside the irrigation barrel 201, a cover plate 302 arranged on the upper part of the water collecting barrel 301 and having an opening, a mounting seat 303 arranged at the lower end of the water collecting barrel 301 and connected to the bottom and inner wall of the irrigation barrel 201, and a drainage pipe 304 arranged at the bottom of the water collecting barrel 301 and penetrating the irrigation barrel 201 and connected to the connecting pipe 103; a protective assembly 5 is slidably arranged on the cover plate 302, and the water collecting assembly 3 is used to collect water exceeding the water level so that the water can overflow into the water collecting assembly 3 and then flow into the return pipe 102 through the water collecting assembly 3.

[0029] When this embodiment is deployed, the height of the return pipe 102 is lower than the height of the water collection component 3, and the irrigation component 2 is buried underground, so that the return pipe 102 is also buried underground. In order to collect rainwater conveniently, it should be built into a conical groove during deployment so that the upper part of the irrigation bucket 201 is located at the lower part of the groove to facilitate the flow of water into the irrigation component 2, and a protective net should be placed above the irrigation component 2 to prevent leaves from falling into the irrigation component 2. The lower end of the irrigation component 2 supports the irrigation bucket 201 through the support seat 203, so that the irrigation hole 204 is separated from the bottom of the soil to avoid direct blockage; the end of the return pipe 102 is located in the water reservoir, and the height of the end is lower than the lower part of the irrigation component 2, so that water can flow into the water reservoir without the need for additional power equipment.

[0030] When in use, the height of the overflow is first adjusted by the adjustment mechanism 7. When irrigation is carried out, the water pump draws out water and transports the water to the connecting pipe 103 through the water inlet pipe 101, and then sends the water to the irrigation bucket 201 through the connecting pipe 103. The water flows into the ground through the irrigation hole 204, which can irrigate the underground. The flow rate entering the irrigation bucket 201 is much greater than the water outlet flow rate of the irrigation bucket 201, and greater than the soil water absorption rate. Therefore, when too much water flows in, in order to avoid water flowing to the surrounding position, the excess water is filtered by the filter cartridge 6 and flows into the water collection bucket 301, and then flows into the connecting pipe 103 through the drainage pipe 304, and flows into the return pipe 102, and flows back to the reservoir through the return pipe 102, thereby avoiding the waste of water resources and allowing water to continuously irrigate the roots of plants at the installation location.

[0031] When it rains, water will gather into the irrigation barrel 201 through the conical groove. When the water level rises, it will be filtered through the filter cartridge 6 and then overflow the regulating mechanism 7, causing the water level to flow into the water collection component 3. Backflow is achieved through the water collection component 3, and the excess rainwater is automatically collected. When needed, water can be directly supplied through the reservoir.

[0032] When the filter cartridge 6 is filtering, if it is not cleaned, dirt will easily adhere to the filter cartridge 6, causing the filter cartridge 6 to be blocked and water cannot overflow. Therefore, when the water level changes, it will drive the cleaning mechanism to operate and clean the inner wall and bottom of the filter cartridge 6, thereby ensuring the smooth flow of the filter cartridge 6 so that it can normally recycle excess water into the reservoir. According to the characteristics of the plant species, a corresponding number of the devices are arranged, wherein the water inlet pipes 101 are arranged separately according to the plant species, so that the same plants can be irrigated uniformly, and the return pipe 102 can share one.

[0033] Embodiment 2 like Figure 1-10 As shown, a plant root irrigation device proposed by the present invention, compared with the first embodiment, the protective component 5 in this embodiment includes a conical cover 501 with an outer diameter larger than the opening and arranged above the cover plate 302, a guide rod 502 arranged on the conical cover 501 and slidably connected to the cover plate 302, and an exhaust frame 503 arranged at the opening of the cover plate 302 and capable of abutting against the conical cover 501.

[0034] In this embodiment, the conical cover 501 is lifted upward to expose the opening, so that when the present invention is deployed, the position of the pressure plate 702 can be easily checked, so that the height of the pressure plate 702 can be controlled according to the type of plant, and the adjustment is convenient. After the adjustment is completed, the conical cover 501 is lowered so that the conical cover 501 falls onto the exhaust rack 503, and the guide rod 502 guides the conical cover 501. The exhaust rack 503 raises the conical cover 501, so that the conical cover 501 can prevent dirt from falling into the water collecting bucket 301 through the opening without affecting the gas flow in the water collecting bucket 301, so that no negative pressure is generated in the water collecting bucket 301, so that according to the principle of communicating vessels, water can overflow into the water collecting component 3.

[0035] Embodiment 3 like Figure 1-10As shown, a plant root irrigation device proposed by the present invention, compared with embodiment one or embodiment two, in this embodiment, a mounting cover 305 is provided at the bottom of the water collecting barrel 301; the filter cartridge 6 is arranged in the mounting cover 305; the adjusting mechanism 7 includes a folding tube 701 arranged on the mounting cover 305 and sealed, a pressing plate 702 arranged on the folding tube 701, a lifting assembly 703 arranged on the cover plate 302 and slidably connected to the pressing plate 702, and a guide rail 704 rotatably arranged on the cover plate 302 and drivingly connected to the pressing plate 702.

[0036] In this embodiment, the mounting cover 305 is used to mount the filter cartridge 6, and can prevent debris from directly adhering to the outer wall of the filter cartridge 6, and at the same time, water can only enter through the filter cartridge 6, and only after the water level moves upward and is filtered by the filter cartridge 6 can it enter the folding tube 701, by rotating the guide rail 704, the guide rail 704 is a screw rod moving structure, and the handle at the upper end of the rotating guide rail 704 drives the screw rod to rotate, so that the screw rod drives the pressure plate 702 to move, and the lifting assembly 703 guides the pressure plate 702, and the pressure plate 702 is moved. 02 drives the folding tube 701 to move, thereby adjusting the position of the upper end of the pressure plate 702 and the position of the overflow water in the irrigation barrel 201, so that the amount of irrigation can be controlled during irrigation, so that the excess water overflows from the top of the pressure plate 702, flows into the water collecting component 3, and then flows back to the water reservoir through the return pipe 102, so that the irrigation amount can be adjusted according to the type of plant to avoid water waste. When it rains, the overflowed water can be collected and returned to the water reservoir, so that water can be collected when it rains.

[0037] Embodiment 4 like Figure 1-10 As shown, a plant root irrigation device proposed by the present invention, compared with embodiment one or embodiment two or embodiment three, the cleaning unit in this embodiment 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 supporting assembly 10 arranged on the filter cartridge 6 and slidably connected to the rotating mechanism 9; the supporting assembly 10 includes a supporting frame 1001 arranged on the filter cartridge 6, a sliding rod 1002 arranged on the supporting frame 1001, and a rotating seat 1003 arranged at the lower end of the sliding rod 1002.

[0038] 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.

[0039] Among them, the rotating rod 901 includes a supporting portion 9011, a threaded portion 9012 arranged on the supporting portion 9011 and threadedly connected to the threaded sleeve 902, a guiding portion 9013 arranged at the lower part of the supporting portion 9011 and slidably connected to the slider 802, and a connecting portion 9014 arranged at the lower part of the guiding portion 9013 and rotatably connected to the filter cartridge 6; the supporting portion 9011 is used for supporting so that it can rotate on the supporting assembly 10, and the threaded portion 9012 is threadedly connected to the threaded sleeve 902, so that when the threaded sleeve 902 moves, the threaded portion 9012 can be driven to rotate, and when the threaded portion 9012 rotates, the supporting portion 9011 is driven to rotate, and the rotation of the supporting portion 9011 will drive the guiding portion 9013 and the connecting portion 9014 to rotate, and the guiding portion 9013 can drive the slider 802 to rotate, thereby driving the cleaning brush 801 to rotate. The guide portion 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 dead weight of the floating block 903 and the buoyancy after water enters the filter cartridge 6. When there is water, the floating block 903 moves upward under the influence of the buoyancy, driving the threaded sleeve 902 to move upward, thereby rotating the rotating rod 901; when the water is drained, it is affected by the gravity of the floating block 903 itself, causing it to move downward, thereby causing the rotating rod 901 to rotate in the opposite direction. When the rotating rod 901 rotates, the filter cartridge 6 can be cleaned, and the filter cartridge 6 can be cleaned once when the water level rises and once again when it drops, thereby ensuring the smooth flow of the filter cartridge 6 and avoiding blockage.

[0040] Furthermore, the cleaning mechanism 8 includes a cleaning brush 801 slidably arranged in the filter cartridge 6 and abutting 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 rotatably connected to the cleaning brush 801 and the pushing sleeve 804 at both ends, and an elastic member 805 arranged on the rotating rod 901 and abutting against the pushing sleeve 804 at the output end; the cleaning brush 801 is driven to move by the rotation of the rotating rod 901, so that the cleaning brush 801 with an L-shaped structure can fit against the bottom and inner wall of the filter cartridge 6 and sweep off the dirt adhered to the filter cartridge 6, thereby preventing the dirt from clogging the filter cartridge 6, so that when collecting water, it can flow more smoothly.

[0041] In this embodiment, the elastic member 805 pushes the pushing sleeve 804 to move downward, the pushing sleeve 804 pushes the connecting rod 803 to move downward, the connecting rod 803 pushes the cleaning brush 801 to move downward, and the cleaning brush 801 drives the slider 802 to move 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 cannot move downward any further. At this time, the force generated by the downward movement of the pushing sleeve 804 will drive the cleaning brush 801 to move toward the inner wall of the filter cartridge 6 through the connecting rod 803, so that the cleaning brush 801 is attached to the slider 80 2, so that the side of the cleaning brush 801 contacts the inner wall of the filter cartridge 6, so that the L-shaped cleaning brush 801 can contact the inner wall and the bottom of the filter cartridge 6, and when the cleaning brush 801 rotates, the filter cartridge 6 can be cleaned to prevent the filter cartridge 6 from being blocked, and the thrust generated by the elastic member 805 enables the cleaning brush 801 to continuously fit with the filter cartridge 6, and when a hard object is stuck on the cleaning brush 801, the cleaning brush 801 can be adaptively adjusted in elasticity, so that the hard object can be knocked away when it hits the hard object next time, or the hard object can be automatically skipped to prevent the cleaning brush 801 from being stuck.

[0042] It is installed on the filter cartridge 6 through the support frame 1001, and 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, and the support frame 1001 cooperates with the rotating seat 1003 to support the rotating rod 901, so that the rotating rod 901 can rotate on the support assembly 10, and the rotation is more stable. 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, and the floating block 903 drives the threaded sleeve 902 to move, thereby driving the rotating rod 901 to rotate through the thread, thereby driving the cleaning mechanism 8 to rotate, so that the cleaning brush 801 can rotate in the filter cartridge 6, clean the inner wall and bottom of the filter cartridge 6, avoid debris adhering to and clogging the mesh of the filter cartridge 6, and ensure the stability of the water flow.

[0043] When the water level gradually drops, the float 903 is affected by its own gravity, causing the float 903 to move downward with the water level, thereby causing the float 903 to drive the threaded sleeve 902 to move downward, causing the rotating rod 901 to rotate in the opposite direction, and then cleaning the inner wall of the filter cartridge 6, thereby enabling secondary cleaning, so that after the water is discharged, it still remains in a clean and unblocked state, so that it is convenient for water to enter the filter cartridge 6 when the water level rises next time.

[0044] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
