Abstract

This invention discloses a water-saving irrigation and fertilization device for balanced irrigation, belonging to the field of irrigation technology. It includes a main irrigation pipe connected to an external pumping device. Multiple expansion interface components are sequentially arrayed around the main irrigation pipe. Each expansion interface component has a detachable connecting component at its top, and a flow control component is connected to the top of the connecting component.

Description

Technical Field

[0001] This invention belongs to the field of irrigation technology, and in particular relates to a water-saving irrigation and fertilization device for balanced irrigation. Background Technology

[0002] With the development of technology, water-saving irrigation and fertilization devices that provide uniform irrigation have gradually emerged. Water-saving irrigation and fertilization devices are an agricultural irrigation technology that aims to improve irrigation efficiency and crop yield by making efficient use of water resources and fertilizers, while reducing the waste of water resources and fertilizers. This includes fertilizer mixing and automated pumping equipment.

[0003] Chinese invention patent CN113039911B discloses a semi-automatic fertilization and irrigation device for karst slopes, comprising a rainwater collection tank, a water-fertilizer mixing tank, and an irrigation network for irrigating plants. A rainwater pipe connects the rainwater collection tank to the irrigation network, a mixing pipe connects the rainwater collection tank to the water-fertilizer mixing tank, and a water-fertilizer pipe connects the water-fertilizer mixing tank to the irrigation network. This solution not only achieves integrated fertilization and irrigation but also semi-automatic operation, effectively solving agricultural fertilization and irrigation problems on karst slopes. It can effectively improve water and fertilizer utilization and reduce agricultural non-point source pollution. However, in actual use, the pumping flow rate at the end of the irrigation and fertilization system usually depends on the pumping intensity of the delivery pump. The pumping volume between multiple branch pipes is usually uniform and cannot be adjusted. Soil conditions, crop types, and growth stages may vary in different areas, resulting in different water and fertilizer requirements, thus presenting certain limitations. Summary of the Invention

[0004] The purpose of this invention is to address the problem that the pumping flow rate in the terminal section of the pipeline usually depends on the pumping intensity of the pump body, and the pumping volume between multiple branch pipes is usually uniform. Therefore, this invention proposes a water-saving irrigation and fertilization device with balanced irrigation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A water-saving irrigation and fertilization device with balanced irrigation includes an irrigation main pipe connected to an external pumping device. Multiple expansion interface components are sequentially arrayed on the outside of the irrigation main pipe. A connecting component is detachably connected to the top of the expansion interface component, and a flow control component is connected to the top of the connecting component. An irrigation branch pipe is connected to the outlet of the flow control component.

[0007] The flow control component includes a closed cover, one side of which is connected to an irrigation branch pipe. Multiple irrigation nozzles are arrayed and connected to the outer periphery of the irrigation branch pipe. A connecting ring is connected to one side of the closed cover, and multiple radially movable turbulence rings are provided inside the connecting ring. The irrigation flow of different irrigation branch pipes is controlled by the combination of multiple turbulence rings.

[0008] As a further description of the above technical solution:

[0009] The inner cavity of the connecting ring is connected to a track ring via a connecting plate. Multiple travel grooves are formed around the axis on one side of the track ring. Travel rods are slidably connected in the travel grooves, and rotating rings are connected between the multiple travel rods. The rotating rings are rotatably connected inside the connecting ring. A disturbance groove is formed on one side of the track ring, and the disturbance groove is located inside the travel groove. A disturbance rod is slidably connected in the disturbance groove. A slide rod is connected to the bottom of the disturbance rod. A guide sleeve is fitted over the slide rod. The guide sleeve is connected to the corresponding position on the top of the rotating ring. The other end of the slide rod is connected to one side of the turbulence ring via a connecting seat. The rotation of the rotating ring drives the disturbance rod to move within the disturbance groove and pushes the turbulence ring to move radially.

[0010] As a further description of the above technical solution:

[0011] Energy-absorbing pads are connected to both sides of the inner cavity of the connecting seat, and the energy-absorbing pads are in contact with the side of the turbulence ring. A sealing ring is connected to the outer periphery of the turbulence ring, and the sealing ring fills the gap between the rotating ring and the track ring to absorb the impact of water flow.

[0012] As a further description of the above technical solution:

[0013] The outer wall of the rotating ring is connected to a limiting plate. Multiple slots are formed around the outer periphery of the limiting plate along the axis. A driving ring is provided on one side of the rotating ring. Insertion blocks are connected to the positions of the slots on one side of the driving ring. The movement of the driving ring drives the insertion blocks to be inserted into the slots, thereby driving the limiting plate and the rotating ring to rotate. The driving ring is rotatably connected to one side of the connecting ring. Multiple handles are provided on the outer periphery of the driving ring.

[0014] As a further description of the above technical solution:

[0015] The connecting ring has an insertion slot on one side, and an anti-detachment block is slidably connected in the insertion slot. A telescopic rod is connected to one side of the anti-detachment block, and the other end of the telescopic rod is connected to one side of the drive ring. A telescopic spring is sleeved on the outer wall of the telescopic rod, and the two ends of the telescopic spring are respectively connected to the corresponding positions of the drive ring and the anti-detachment block. The insertion slot has an L-shaped cross-section, and the anti-detachment block is limited to detach by the stepped block of the insertion slot.

[0016] As a further description of the above technical solution:

[0017] The connecting assembly includes an outer fixed base and a connecting cylinder. The connecting cylinder is connected to the inner side of the connecting ring. The outer fixed base communicates with the outside of the main irrigation pipe. The expansion interface assembly includes an expansion seat, which is installed inside the connecting assembly. The expansion seat has openings on both sides for irrigation water to flow through. A sealing block is slidably connected to one side of the expansion seat. An abutment ring is connected to one side of the sealing block. A support ring is connected to the other side of the abutment ring via a sealing spring. The support ring is connected to the side of the expansion seat cavity away from the sealing block. The sealing spring's elasticity drives the sealing block to close the opening of the expansion seat. A force-bearing ring is connected to the side of the sealing block away from the opening of the expansion seat. The connecting cylinder is detachably connected to the outer fixed base. The sealing gap between the sealing block and the expansion seat is opened by squeezing the force-bearing ring from the inside of the connecting cylinder.

[0018] As a further description of the above technical solution:

[0019] Both the sealing block and the expansion seat opening are tapered, with the smaller tapered end of the sealing block closer to the connecting cylinder.

[0020] As a further description of the above technical solution:

[0021] The connecting cylinder has sliders connected to both sides of its outer wall, and the outer fixed seat has sliding grooves on both sides of its inner cavity. The inner walls of the sliding grooves on both sides that are far apart have limit grooves, and the cross-sectional shape of the limit grooves is arc-shaped. The sliders and the connecting cylinder are axially moved by the stepped part on the side wall of the limit groove.

[0022] As a further description of the above technical solution:

[0023] An elastic pad is connected to the bottom of the slider, which fills the gap between the slider and the limiting groove.

[0024] As a further description of the above technical solution:

[0025] The inner side of the force ring is connected to a column through multiple guide plates, and the column is connected to the top of the closed block. The multiple guide plates are set at an inclined angle to guide the irrigation water to the irrigation branch pipe.

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

[0027] 1. In this invention, through the designed flow control component, after the external pumping mechanism fully mixes the fertilizer and water, it can pump the mixture into the irrigation main pipe. By pulling the drive ring, the inner limiting plate and the rotating ring are rotated. The rotating ring can drive the top disturbance rod to rotate in the disturbance groove. The disturbance rod can move from the side of the disturbance groove located on the outer edge to the side of the disturbance groove located on the inner edge through rotational disturbance, realizing the radial movement of the disturbance rod inward. The movement of the disturbance rod can pull the bottom slide rod, the front connecting seat, and the turbulence ring to move. The multiple turbulence rings on the periphery move inward synchronously, which can reduce the water and fertilizer flow gap in the closed cover, control the pumping volume of the irrigation branch of the current irrigation branch pipe, and facilitate the selection of flow rate in different irrigation branch pipes to meet the water and fertilizer application needs of different areas, thereby improving fertilizer utilization efficiency.

[0028] 2. In this invention, the drive ring is designed such that, in the normal state, the insertion block is not inserted into the groove. When the drive ring rotates, it rotates in the insertion groove on one side of the connecting ring through the circumferential telescopic rod and the anti-detachment block. This prevents the insertion block in the uninserted state from driving the limiting plate and the rotating ring to rotate, thus avoiding external accidental contact that could cause displacement of the inner turbulence ring and affect the stability of the pumping system. The insertion block can be inserted into the groove of the limiting plate for connection and cooperation, and can rotate the drive ring to drive the inner rotating ring to rotate for driving control of the turbulence ring.

[0029] 3. In this invention, through the designed connecting components, the closing spring can use its own elastic force to drive the front closing block to close the opening gap of the expansion seat. It can close the overflow port of the main irrigation pipe when the irrigation branch pipe is not connected, which is beneficial for expanding the irrigation branch pipe to the corresponding position as needed. It is also beneficial for adapting to the extended irrigation needs of different areas through modular expansion. After the irrigation branch pipe is inserted into the outer fixed seat through the bottom connecting cylinder, the inner side of the connecting cylinder can abut against the force ring. The force ring is pressed and can squeeze the closing block to move to the side with the larger diameter of the conical part. After the closing block moves, it can open the gap to allow the irrigation fertilizer to enter the rear irrigation branch pipe. The rapid expansion of the irrigation branch pipe and the establishment of the connection of the pumping pipeline are realized through the sealable gap, which improves the modular expansion efficiency.

Detailed Implementation

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Please see Figures 1-12 The present invention provides a technical solution: a water-saving irrigation and fertilization device for balanced irrigation, including an irrigation main pipe 1 connected to an external pumping device, a plurality of expansion interface components 2 connected in a series array to the outside of the irrigation main pipe 1, a connecting component 3 detachably connected to the top of the expansion interface component 2, and a flow control component 4 connected to the top of the connecting component 3, and an irrigation branch pipe 5 connected to the outlet of the flow control component 4.

[0046] The flow control component 4 includes a closed cover 417, one side of which is connected to the irrigation branch pipe 5. Multiple irrigation nozzles 6 are arrayed around the outer periphery of the irrigation branch pipe 5. The irrigation nozzles 6 can be arranged in a single row or around the outside of the irrigation branch pipe 5, and can be customized according to the irrigation range. A connecting ring 401 is connected to one side of the closed cover 417. Multiple radially movable turbulence rings 411 are provided inside the connecting ring 401. The irrigation flow of different irrigation branch pipes 5 can be controlled by the combination of multiple turbulence rings 411.

[0047] The inner cavity of the connecting ring 401 is connected to the track ring 403 via a connecting plate. Multiple travel grooves 404 are formed around the axis on one side of the outer edge of the track ring 403. Travel rods 407 are slidably connected within the travel grooves 404, and rotating rings 406 are connected between the multiple travel rods 407. The rotating rings 406 are rotatably connected within the connecting ring 401. A disturbance groove 405 is formed on one side of the inner edge of the track ring 403, located inside the travel grooves 404. A disturbance rod 410 is slidably connected within the disturbance groove 405, and a sliding rod 409 is connected to the bottom of the disturbance rod 410. The outer sleeve 408 is connected to the corresponding position on the top of the rotating ring 406. The other end of the slide rod 409 is connected to one side of the turbulence ring 411 through the connecting seat 418. The rotation of the rotating ring 406 drives the turbulence rod 410 to move within the turbulence groove 405 and pushes the turbulence ring 411 to move radially. Energy-absorbing pads are connected to both sides of the inner cavity of the connecting seat 418, and the energy-absorbing pads are in contact with the side of the turbulence ring 411. A sealing ring is connected to the outer periphery of the turbulence ring 411, and the sealing ring fills the gap between the rotating ring 406 and the track ring 403 to absorb the impact of water flow.

[0048] The travel of the two ends of the disturbance groove 405 is located inside and outside the track ring 403, respectively. The radial position of the bottom slide rod 409 is adjusted by moving the disturbance rod 410 within the disturbance groove 405.

[0049] Specifically, through the designed flow control component 4, after the external pumping mechanism has fully mixed the fertilizer and water, it can be pumped into the irrigation main pipe 1. At this time, by pulling the drive ring 412, the inner limit plate 402 and the rotating ring 406 can be rotated. The rotating ring 406 can drive the top disturbance rod 410 to rotate in the disturbance groove 405. The disturbance rod 410 can move from the side of the disturbance groove 405 located on the outer edge to the side of the disturbance groove 405 located on the inner edge through rotational disturbance, thereby realizing the radial movement of the disturbance rod 410 inward. The movement of the disturbance rod 410 can pull the bottom slide rod 409, the front connecting seat 418, and the turbulence ring 411 to move. The multiple turbulence rings 411 on the periphery move inward at the same time, which can reduce the water and fertilizer flow gap in the closed cover 417, thereby controlling the pumping volume of the irrigation branch of the current irrigation branch pipe 5. This is beneficial for selecting the flow rate in different irrigation branch pipes 5, and there is no need to set up an electromagnetic pump body, reducing the probability of later damage.

[0050] Furthermore, the slide bar 409 can be limited by the guide sleeve 408 when it moves, thereby ensuring the stable radial movement of the front turbulence ring 411 through the guide sleeve 408. The turbulence ring 411 can reduce the bounce during water flushing through the energy-absorbing pad in the connecting seat 418, thereby improving the turbulence stability. In addition, the turbulence ring 411 can fill the gap through the outer sealing ring, avoiding leakage when the turbulence ring 411 is in the unfolded or contracted state, thereby improving the stability of use.

[0051] Please see Figures 3-4 A limiting plate 402 is connected to the outer wall of the rotating ring 406. Multiple slots are formed around the outer periphery of the limiting plate 402 along its axis. A driving ring 412 is provided on one side of the rotating ring 406. Insertion blocks 414 are connected to the driving ring 412 at positions corresponding to the slots. Movement of the driving ring 412 causes the insertion blocks 414 to insert into the slots, thereby rotating the limiting plate 402 and the rotating ring 406. The driving ring 412 is rotatably connected to one side of the connecting ring 401. Multiple handles are provided on the outer periphery of the driving ring 412. 413. A insertion groove 416 is provided on one side of the connecting ring 401. An anti-detachment block 415 is slidably connected in the insertion groove 416. A telescopic rod is connected to one side of the anti-detachment block 415, and the other end of the telescopic rod is connected to one side of the drive ring 412. A telescopic spring is sleeved on the outer wall of the telescopic rod. The two ends of the telescopic spring are respectively connected to the corresponding positions on one side of the drive ring 412 and the anti-detachment block 415. The cross-sectional shape of the insertion groove 416 is L-shaped. The anti-detachment block 415 is detached by the stepped block of the insertion groove 416.

[0052] Specifically, through the designed drive ring 412, the insertion block 414 is not inserted into the groove in the normal state. When the drive ring 412 rotates, it can rotate in the insertion groove 416 on one side of the connecting ring 401 through the peripheral telescopic rod and the anti-detachment block 415. This prevents the insertion block 414 in the uninserted state from driving the limit plate 402 and the rotating ring 406 to rotate, thus avoiding external accidental contact that causes the inner turbulence ring 411 to be displaced and affects the stability of the pumping system.

[0053] When adjustment is needed, the drive ring 412 is moved by pulling the handle 413 from the outside. After the drive ring 412 is moved along the axis of the connecting ring 401, the insertion block 414 can be inserted into the groove of the limiting plate 402 for connection and engagement. At this time, the drive ring 412 can be rotated to drive the inner rotating ring 406 to rotate and drive the turbulence ring 411. Through the designed telescopic rod, the telescopic rod can move the drive ring 412 by contraction, and the telescopic spring can use its own spring to ensure the automatic reset effect of the drive ring 412 when the handle 413 is released.

[0054] Please see Figure 7 and Figure 11 The connecting assembly 3 includes an outer fixed base 302 and a connecting cylinder 301. The connecting cylinder 301 is connected to the inner side of the connecting ring 401, and the outer fixed base 302 is connected to the outside of the irrigation main pipe 1. The expansion interface assembly 2 includes an expansion seat 201, which is installed inside the connecting assembly 3. The expansion seat 201 has openings on both sides for irrigation water to flow through. A closing block 205 is slidably connected to one side of the expansion seat 201, and an abutment ring 204 is connected to one side of the closing block 205. A support ring 202 is connected to the other side of the abutment ring 204 via a closing spring 203. The support ring 202 is connected to... The side of the inner cavity of the expansion seat 201 away from the closing block 205 is closed by the elastic force of the closing spring 203, which drives the closing block 205 to close the opening of the expansion seat 201. The side of the closing block 205 away from the opening of the expansion seat 201 is connected to a force ring 206. The connecting cylinder 301 is detachably connected to the outer fixed seat 302. The closing gap between the closing block 205 and the expansion seat 201 is opened by squeezing the force ring 206 on the inner side of the connecting cylinder 301. Both the opening of the closing block 205 and the expansion seat 201 are tapered, and the end of the tapered block 205 with a smaller diameter is closer to the side of the connecting cylinder 301.

[0055] Specifically, through the designed connecting component 3, when the outer fixed seat 302 is connected to the outside of the irrigation main pipe 1, the closing spring 203 can use its own elastic force to drive the front closing block 205 to close the opening gap of the expansion seat 201, thereby closing the overflow port of the irrigation main pipe 1 when the irrigation branch pipe 5 is not connected. This is beneficial for expanding the irrigation branch pipe 5 to the corresponding position as needed, and for adapting to the extended irrigation needs of different areas through modular expansion. Furthermore, after the irrigation branch pipe 5 is inserted into the outer fixed seat 302 through the bottom connecting cylinder, the inner side of the connecting cylinder 301 can abut against the force ring 206. The force ring 206, under pressure, can squeeze the closing block 205 to move towards the side with a larger diameter of the conical part. After the closing block 205 moves, it can open the gap to allow irrigation fertilizer to enter the rear irrigation branch pipe 5. This enables the rapid expansion of the irrigation branch pipe 5 and the establishment of connection of the pumping pipeline through the sealable gap, thereby improving the modular expansion efficiency.

[0056] Furthermore, a stepped ring or extension block may be provided on the inner side of the connecting cylinder 301 to ensure that the force-bearing ring 206 can be fully compressed;

[0057] The inner side of the force-bearing ring 206 is connected to a column via multiple guide plates 207, and the column is connected to the top of the sealing block 205. The multiple guide plates 207 are set at an inclined angle to guide the irrigation water to the irrigation branch pipe 5.

[0058] The designed guide plate 207 allows the water overflowing from the extension seat 201 to generate spiral kinetic energy through the inclined guide plate 207, reducing disturbance to the irrigation fertilizer.

[0059] Both sides of the outer wall of the connecting cylinder 301 are connected to sliders 305. Both sides of the inner cavity of the outer fixed seat 302 are provided with sliding grooves 303. On the side of the inner wall of the sliding grooves 303 that are far apart, there are limiting grooves 304. The cross-sectional shape of the limiting grooves 304 is arc-shaped. The sliders 305 and the connecting cylinder 301 are limited to move axially by the stepped part on the side wall of the limiting grooves 304. An elastic pad is connected to the bottom of the sliders 305 to fill the gap between the sliders 305 and the limiting grooves 304.

[0060] Specifically: Through the designed slider 305 and groove 303, when the connecting cylinder 301 is inserted into the end of the inner groove 303 of the outer fixed seat 302 by the sliders 305 on both sides, the slider 305 can slide into the end of the limiting groove 304 by rotating the connecting cylinder 301, thereby completing the connection between the connecting cylinder 301 and the outer fixed seat 302. The slider 305 can fully seal the connecting cylinder 301 and the outer fixed seat 302 through the bottom elastic pad, avoiding shaking and displacement, and improving connection stability.
