In the present invention, through the designed flow control component, when the external pumping mechanism fully mixes the fertilizer and water, it can be pumped into the irrigation main pipe. After the inner limit plate and the swivel are driven to rotate by pulling the driving ring, the swivel can drive the top disturbance rod to rotate in the disturbance groove by rotation. 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 rotation disturbance, so as to realize the radial movement of the disturbance rod inward. The movement of the disturbance rod can pull the bottom sliding rod, the front connecting seat and the spoiler ring to move.

[0029] 3. In the present invention, through the designed connecting component, the closing spring can use its own elastic force to drive the front closing block to close the open gap of the expansion seat, and can close the overflow port of the irrigation main pipe when the irrigation branch pipe is not connected, which is conducive to expanding the irrigation branch pipe at the corresponding position according to needs, and is conducive to adapting to the extended irrigation needs of different areas through modular expansion.

After the closing block moves, the gap can be opened to allow irrigation fertilizer to enter the rear irrigation branch pipe. The rapid expansion of the irrigation branch pipe and the establishment of connection of the pumping pipeline are realized through the closable gap, thereby improving the efficiency of modular expansion.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] See also Figure 1-Figure 12 The present invention provides a technical solution: a water-saving fertilization device with balanced irrigation, comprising an irrigation main pipe 1 connected to an external pumping device, a plurality of expansion interface components 2 are connected to the outside of the irrigation main pipe 1 in an array in sequence, a connection component 3 is detachably connected to the top of the expansion interface component 2, and a flow control component 4 is connected to the top of the connection component 3, and an irrigation branch pipe 5 is connected to the outlet of the flow control component 4;

[0046] The flow control assembly 4 includes a closed cover 417, one side of which is connected to the irrigation branch pipe 5, and a plurality of irrigation nozzles 6 are connected to the outer peripheral side of the irrigation branch pipe 5 in an array, wherein the irrigation nozzles 6 can be arranged outside the irrigation branch pipe 5 in a single row or in a circle, and can be customized and adjusted according to the irrigation range requirements, and one side of the closed cover 417 is connected to a connecting ring 401, and a plurality of radially movable spoiler rings 411 are arranged in the connecting ring 401, and the irrigation flow of different irrigation branches 5 is regulated by the combination of the plurality of spoiler rings 411;

[0047] The inner cavity of the connecting ring 401 is connected to the track ring 403 through a connecting plate. A plurality of travel grooves 404 are formed around the axis on the outer edge of one side of the track ring 403. A travel rod 407 is slidably connected in the travel groove 404. A rotating ring 406 is connected between the plurality of travel rods 407. The rotating ring 406 is rotatably connected in the connecting ring 401. A disturbance groove 405 is formed on the inner edge of one side of the track ring 403. The disturbance groove 405 is located on the inner side of the travel groove 404. A disturbance rod 410 is slidably connected in the disturbance groove 405. A sliding rod 409 is connected to the bottom of the disturbance rod 410. The sliding rod 409 is connected to the bottom of the sliding rod 409. The outer sleeve 09 is provided with a guide sleeve 408, which is connected to the corresponding position of the top of the swivel 406. The other end of the slide rod 409 is connected to one side of the spoiler ring 411 through the connecting seat 418. The swivel 406 rotates to drive the disturbance rod 410 to move in the disturbance groove 405 and push the spoiler 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 fitted with the sides of the spoiler ring 411. A sealing ring is connected to the outer peripheral side of the spoiler ring 411, and the sealing ring fills the gap between the swivel 406 and the track ring 403 to absorb the impact of water flow.

[0048] The travel ends of both sides of the disturbance groove 405 are located at the inner side and the outer side of the track ring 403 respectively, and the radial position of the bottom slide bar 409 is adjusted by moving the disturbance rod 410 in the disturbance groove 405;

[0049] Specifically, through the designed flow control component 4, when the external pumping mechanism fully mixes the fertilizer and water, it can be pumped into the irrigation main pipe 1. At this time, the inner limit plate 402 and the swivel 406 can be driven to rotate by pulling the driving ring 412, and the swivel 406 can drive the top disturbance rod 410 to rotate in the disturbance groove 405 by rotation. 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 rotation disturbance, thereby realizing the radial movement of the disturbance rod 410 inward. The movement of the disturbance rod 410 can pull the bottom slide bar 409, the front connecting seat 418 and the spoiler ring 411 to move. The multiple spoiler rings 411 on the peripheral side move inward synchronously, which can reduce the water and fertilizer circulation gap in the closed cover 417, thereby controlling the pumping amount of the irrigation branch of the current irrigation branch pipe 5, which is conducive to selecting the circulation flux in different irrigation branch pipes 5, and there is no need to set up an additional electromagnetic pump body, thereby reducing the probability of later damage.

[0050] Furthermore, the slide rod 409 can be limited by the guide sleeve 408 when moving, so that the stable radial movement of the front spoiler ring 411 can be guaranteed by the limitation of the guide sleeve 408, and the spoiler ring 411 can reduce the bounce during water flushing through the energy-absorbing pad in the connecting seat 418, thereby improving the spoiler stability, and the spoiler ring 411 can fill the gap through the sealing ring on the outer periphery to avoid leakage when the spoiler ring 411 is expanded or contracted, thereby improving the stability of use.

[0051] See also Figure 3-Figure 4 The outer wall of the rotating ring 406 is connected to the limit plate 402, and a plurality of grooves are opened around the outer peripheral side of the limit plate 402 along the axis. A driving ring 412 is provided on one side of the rotating ring 406, and the positions corresponding to the grooves on one side of the driving ring 412 are connected with insertion blocks 414. The insertion blocks 414 are inserted into the grooves by moving the driving ring 412 to drive the limit plate 402 and the rotating ring 406 to rotate. The driving ring 412 is rotatably connected to one side of the connecting ring 401, and a plurality of handles are provided on the outer peripheral side of the driving ring 412 413, an insertion groove 416 is provided on one side of the connecting ring 401, and an anti-slip block 415 is slidably connected in the insertion groove 416, a telescopic rod is connected to one side of the anti-slip block 415, and the other end of the telescopic rod is connected to one side of the driving ring 412, and a telescopic spring is provided 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 driving ring 412 and one side of the anti-slip block 415, and the cross-sectional shape of the insertion groove 416 is L-shaped, and the anti-slip block 415 is limited by the step block of the insertion groove 416 to slip out.

[0052] Specifically, the drive ring 412 is designed so that the insertion block 414 of the drive ring 412 is not inserted into the slot body in the normal state. At this time, when the drive ring 412 rotates, it can rotate in the insertion slot 416 on one side of the connecting ring 401 through the peripheral telescopic rod and the anti-dropping block 415, so that the insertion block 414 in the uninserted state cannot drive the limit plate 402 and the rotating ring 406 to rotate, thereby preventing the inner spoiler ring 411 from being displaced due to external accidental touch and affecting the stability of the pumping system.

[0053] When adjustment is needed, the drive ring 412 is pulled to move by the handle 413 from the outside. After the drive ring 412 is pushed to move along the axial direction of the connecting ring 401, the insertion block 414 can be inserted into the groove of the limiting plate 402 for connection. At this time, the drive ring 412 can be rotated to drive the inner rotating ring 406 to rotate to control the drive of the spoiler ring 411. The designed 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] See also Figure 7 and Fig.11 The connection assembly 3 includes an outer fixing seat 302 and a connecting tube 301, the connecting tube 301 is connected to the inner side of the connecting ring 401, the outer fixing seat 302 is connected to the outside of the irrigation main pipe 1, the expansion interface assembly 2 includes an expansion seat 201, the expansion seat 201 is installed in the connection assembly 3, both sides of the expansion seat 201 have openings for the circulation of irrigation water, and one side of the expansion seat 201 is slidably connected to a closing block 205, one side of the closing block 205 is connected to an abutting ring 204, and the other side of the abutting ring 204 is connected to a supporting ring 202 through a closing spring 203, and the supporting ring 202 is connected to The side of the inner cavity of the expansion seat 201 away from the closing block 205 is driven by the elastic force of the closing spring 203 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 with a force ring 206. The connecting tube 301 is detachably connected to the outer fixing seat 302. The closed gap between the closing block 205 and the expansion seat 201 is opened by squeezing the force ring 206 from the inner side of the connecting tube 301. The openings of the closing block 205 and the expansion seat 201 are both conical parts, and the end of the closing block 205 with a smaller conical diameter is close to the side of the connecting tube 301.

[0055] Specifically, through the designed connection component 3, when the outer fixing 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 side closing block 205 to close the opening gap of the expansion seat 201, so that the overflow port of the irrigation main pipe 1 can be closed when the irrigation branch pipe 5 is not connected, which is conducive to expanding the irrigation branch pipe 5 at the corresponding position according to needs, and is conducive to adapting to the extended irrigation needs of different areas through modular expansion. In addition, after the irrigation branch pipe 5 is inserted into the outer fixing seat 302 through the bottom connecting tube, the inner side of the connecting tube 301 can resist the stress ring 206, and the stress ring 206 can be pressed to squeeze the closing block 205 to move to the side with a larger diameter of the tapered portion. After the closing block 205 moves, the gap can be opened to allow the irrigation fertilizer to enter the rear irrigation branch pipe 5, so that the irrigation branch pipe 5 can be quickly expanded and the pumping pipeline can be connected through the closable gap, thereby improving the modular expansion efficiency.

[0056] Furthermore, a corresponding step ring or extension block may be provided inside the connecting tube 301 to ensure that the stress ring 206 can be fully squeezed;

The plurality of guide plates 207 are arranged at an inclined angle to guide the irrigation water to be led out to the irrigation branch pipe 5.

[0058] By means of the designed guide plate 207, the water overflowing from the expansion seat 201 can generate spiral kinetic energy through the inclined guide plate 207, thereby reducing the disturbance to the irrigation of fertilizers.
