Description

Technical Field

[0001] The invention belongs to the technical field of fruit tree irrigation, and specifically refers to a precise fertilization device and method for cultivating large seedlings of fruit trees in containers. Background Art

[0002] Container seedling cultivation refers to the seedling cultivation technology of using specific containers to cultivate crop or fruit trees, flowers, and forest seedlings. Since the root systems of adjacent plants are not connected and have independent growth environments, it is beneficial to ensure the nutrient supply of each plant, and it is less likely to have large and increasing differences in plant growth due to different abilities to compete for nutrients.

[0003] The common irrigation method for container seedling cultivation is to lead branch pipes from the main pipe to each independent container. Not only water, but other nutrients can also be dissolved in water and transported by irrigation;

[0004] The traditional irrigation method is to directly lead branch pipes from the main pipe. However, since the pipes are buried in the soil, their blockage conditions and discharge pressures are different, resulting in different and uncontrollable liquid flow rates in the branches. Therefore, it is difficult to ensure that each container receives the same amount of water and nutrients within the same irrigation time.

[0005] In addition, if you want to increase or decrease the irrigation amount of a certain plant due to the growth needs of the individual plant, it is difficult to achieve individual flow feedback and control of the branch. Summary of the invention

[0006] In view of the above situation, in order to overcome the defects of the prior art, the present invention proposes a precise fertilization device and method capable of accurately and independently controlling the liquid flow of each branch. In order to feedback the liquid flow in the channel-type flow control housing, the present invention first proposes a method of impeller rotation sensing. However, since the liquid flows between the impellers, the rotation speed of the impeller is positively correlated with the liquid flow rate, but not proportional. That is to say, the same amount of liquid drives the impeller at different flow rates, and the rotation angle of the impeller is different. The opening and closing of the valve opening and closing assembly is connected to the rotation angle of the impeller through a threaded transmission. In order to solve the error caused by flow rate fluctuations, the present invention creatively proposes a quantitative rotation mechanism, which ensures that the flow rate is proportional to the rotation angle through a rotary wheel-type quantitative liquid intake and discharge method, thereby achieving the technical goal of precise quantitative fertilization even when the flow rate is different and unknown.

[0007] Not only that, by manually pulling the pull ring, not only can the valve opening and closing assembly be opened simply and conveniently, but the watering amount of a single branch can also be preset by the length of the pulled thin rope.

[0008] The technical solution adopted by the present invention is as follows: The present invention proposes a precise fertilization device for cultivating large seedlings in fruit trees in containers, comprising a container seedling cultivation mechanism, a flow setting control mechanism and a quantitative rotation mechanism. The container seedling cultivation mechanism comprises a main pipeline and a seedling cultivation container assembly, and the main pipeline is arrayed with branch joints and tail pipe parts.

[0009] Preferably, the seedling container assembly includes a seedling container body, an annular irrigation pipe and a seedling body, the end of the channel-type flow control shell is connected to the annular irrigation pipe, and the inner part of the annular irrigation pipe is evenly distributed with infiltration tubes, the annular irrigation pipe is located in the seedling container body, and the seedling body is located in the annular irrigation pipe.

[0010] The container seedling raising mechanism can be used to water and fertilize individually cultivated plants (it can also be fertilized by dissolving the fertilizer in water and watering), which helps to control the nutrient distribution of each plant and avoid the situation where nearby plants compete for nutrients during concentrated cultivation.

[0011] Furthermore, the flow setting control mechanism includes a channel-type flow control housing, a threaded fitting component, a pull-rope type adjustment component, an impeller rotation component and a valve opening and closing component, the channel-type flow control housing is arranged on the branch joint, the threaded fitting component is arranged in the channel-type flow control housing, the pull-rope type adjustment component is arranged on the threaded fitting component, the impeller rotation component is snap-fitted in the threaded fitting component, and the valve opening and closing component is arranged in the channel-type flow control housing.

[0012] The flow setting control mechanism can independently and accurately control the watering amount of each plant, and can automatically close the branch flow channel where it is located after the watering is completed. This branch closure does not affect the watering of other plants, so the technical effect of automatically completing quantitative watering can be achieved without manual operation.

[0013] Preferably, the threaded mating assembly includes a threaded bushing, a rotary propulsion sleeve and a U-shaped spring piece, the threaded bushing is fixedly connected to the inner wall of the channel-type flow control housing, the rotary propulsion sleeve is rotatably arranged in the channel-type flow control housing, one end of the rotary propulsion sleeve is provided with an inner sleeve and an outer sleeve, the outside of the outer sleeve is provided with an external threaded portion, the outer sleeve is provided with dividing grooves evenly distributed in an annular manner, the other end of the rotary propulsion sleeve is also provided with guide bosses evenly distributed in an annular manner, and the U-shaped spring piece is arranged between the inner sleeve and the outer sleeve.

[0014] Through the cooperation of the rotary push sleeve and the threaded bushing, the rotary push sleeve can gradually approach the quantitative rotation mechanism when rotating, thereby controlling the gap between the valve seat and the valve core. When the valve seat and the valve core are fitted, the entire branch will be closed.

[0015] As a further preferred embodiment of the present invention, the pull rope type adjustment assembly includes an adjustment pull rope and a pull rope sealing ring, one end of the adjustment pull rope is evenly distributed with thin rope parts in a ring shape, the ends of the thin rope parts are connected to the outer sleeve, the number of the thin rope parts is the same as the number of the dividing grooves, the end of the adjustment pull rope is provided with a pull ring, the pull rope sealing ring is snap-fitted in the tail pipe part, and the adjustment pull rope is snap-fitted and slidably arranged in the pull rope sealing ring.

[0016] By means of the separation grooves arranged on the outer sleeve, the outer sleeve can be divided into multiple independent elastic sheets. Combined with the design of the pulling direction of the adjustment rope, the technical effect of automatically separating the external threaded part from the threaded bushing when the adjustment rope is pulled and automatically combining the external threaded part and the threaded bushing when the adjustment rope is loosened can be achieved.

[0017] Preferably, the impeller rotating assembly comprises a locking sleeve and an impeller body, the locking sleeve is locked on the inner wall of the rotating propulsion sleeve, the impeller body is fixedly connected to the inner wall of the locking sleeve, and a central axis is provided at the central position of the impeller body.

[0018] The thrust generated by the water flow passing through the impeller body can drive the rotating propulsion sleeve and the rotary quantitative circulation component to rotate. On the one hand, it can change the axial position of the rotating propulsion sleeve in the channel-type flow control housing in combination with the threaded fit; on the other hand, it can also enable the quantitative rotating mechanism to complete the function of quantitative discharge through the relative rotation of the rotary quantitative circulation component and the fixed liquid inlet and discharge component.

[0019] As a further preferred embodiment of the present invention, the valve opening and closing assembly includes a valve seat and a valve core, the valve seat is clamped in a rotary quantitative circulation assembly, the valve core is clamped in a rotating propulsion sleeve, and the valve seat is annularly evenly provided with through holes, and the through holes can be closed when the valve core and the valve seat are in contact.

[0020] Furthermore, the quantitative rotating mechanism includes a rotary quantitative circulation component, a fixed liquid inlet and discharge component and a quantitative liquid discharge component, the rotary quantitative circulation component is rotatably arranged in a channel type flow control housing, the rotary quantitative circulation component is arranged on a threaded mating component, the fixed liquid inlet and discharge component is snap-fitted in the channel type flow control housing, and the quantitative liquid discharge component is evenly distributed in an annular shape on the rotary quantitative circulation component.

[0021] The quantitative rotating mechanism can strictly limit the relationship between flow rate and rotation angle through the successive quantitative discharge of the rotary sleeve, so that the two parameters of "flow rate" and "rotation angle" originally affected by multiple factors now have a strict positive proportional relationship, thereby making the relationship of "reflecting the liquid flow rate according to the rotation angle of the rotating propulsion sleeve" more stable and controllable.

[0022] Preferably, the rotary quantitative circulation component includes a rotary wheel bracket and a rotary wheel sleeve, the rotary wheel bracket is rotatably arranged in a channel-type flow control housing, the rotary wheel bracket is provided with a mounting frame, the rotary wheel sleeve is clamped in the mounting frame, a plurality of groups of rotary wheel sleeves are evenly distributed in an annular shape, the inner wall of the rotary wheel bracket is also provided with a guide groove that slides with the guide boss, and the valve seat is fixedly connected to the rotary wheel bracket.

[0023] The impeller sleeve rotates together with the impeller bracket and the rotating propulsion sleeve driven by the impeller body, but the flow rate through the quantitative rotating mechanism is strictly limited by the impeller sleeve. Therefore, the rotation angle of the impeller quantitative circulation component can actually ignore the influence of error factors such as flow rate, and directly feedback the liquid flow rate through the quantitative rotating mechanism.

[0024] As a further preferred embodiment of the present invention, the fixed liquid inlet and discharge assembly includes an I-shaped disc bracket and a magnetic ring, the I-shaped disc bracket is composed of a first disc, a second disc and a connecting column, the I-shaped disc bracket is fixedly connected to the inner wall of the channel type flow control shell through the second disc, the first disc is provided with a liquid inlet hole, the second disc is provided with an arc-shaped liquid discharge groove, the magnetic ring is snap-fitted into the liquid inlet hole, and the same rotor sleeve is not connected to the liquid inlet hole and the arc-shaped liquid discharge groove at the same time.

[0025] When the wheel sleeve passes through the liquid inlet circular hole, it can be filled with liquid under the action of water pressure and magnetic attraction. When passing through the arc-shaped liquid discharge groove, the liquid in the liquid inlet circular hole will be discharged quantitatively under the action of water pressure and elastic force. Since the amount of liquid discharged from the liquid inlet circular hole each time is roughly equal, the rotation angle of the wheel bracket can reflect the amount of liquid flowing through the quantitative rotating mechanism.

[0026] As a further preferred embodiment of the present invention, the quantitative discharge assembly includes an accordion-type hollow bag, a diaphragm one-way valve and a discharge spring. One end of the accordion-type hollow bag is fixedly connected to a magnetic ring, and the other end of the accordion-type hollow bag is provided with a magnetic block. The magnetic block slides in the rotor sleeve with the end of the accordion-type hollow bag. The diaphragm one-way valve is fixedly connected to one end of the accordion-type hollow bag, and the diaphragm one-way valve and the magnetic block are located at the same end of the accordion-type hollow bag. The discharge spring is arranged between the magnetic block and the end mounting ring of the liquid inlet hole.

[0027] The present invention also proposes a method for using a precise fertilization device for cultivating large seedlings in fruit trees containers, which mainly comprises the following steps:

[0028] Step 1: Water or nutrient solution containing dissolved fertilizers is transported through the main pipeline. When the valve opening and closing assembly is in the open state, the liquid flows into the annular irrigation pipe through the channel flow control housing, and then diffuses to the root area around the seedling body through the infiltration pipe;

[0029] Step 2: When the liquid flows through the impeller body, the impact of the liquid on the impeller body can cause the impeller rotating assembly to rotate. The impeller rotating assembly will also cause the rotating propulsion sleeve and the rotary quantitative circulation assembly to rotate together. When the rotating propulsion sleeve rotates, due to the thread matching between the external thread part and the threaded bushing, the position of the rotating propulsion sleeve will gradually approach the quantitative rotating mechanism, and the distance between the valve seat and the valve core will gradually decrease;

[0030] Step 3: As the runner bracket slowly rotates along with the rotating propulsion sleeve, the same runner sleeve will not be connected to the liquid inlet circular hole and the arc-shaped liquid discharge groove at the same time. Therefore, when the runner sleeve is connected to the liquid inlet circular hole, the end of the runner sleeve close to the second disc is blocked. At this time, since the water pressure in the main pipeline is high and the liquid can flow in one direction through the diaphragm one-way valve, water will enter the runner sleeve and compress the air in the accordion-type hollow bag.

[0031] Step 4: As the accordion-type hollow air bag is compressed, the length of the accordion-type hollow air bag is shortened, and the distance between the magnetic block and the magnetic ring gradually approaches. During this movement, the water pressure and the magnetic attraction force are superimposed on each other, with the water pressure dominating in the front section and the magnetic attraction force dominating in the back section until the magnetic block moves to the limit position;

[0032] Step 5: As the wheel bracket continues to rotate, when the wheel sleeve is no longer connected to the liquid inlet circular hole but connected to the arc-shaped drainage groove, after the magnetic attraction is lost, the liquid in the wheel sleeve will be discharged through the arc-shaped drainage groove under the combined action of the air pressure in the accordion-type air bag and the elastic force of the drainage spring.

[0033] Step 6: When the input water pressure of the main pipeline is stable, the amount of liquid inhaled and discharged by the impeller sleeve each time is also stable. Therefore, the flow through the branch is positively correlated with the rotation angle of the impeller bracket. By setting the number of rotations of the rotating propulsion sleeve, the amount of liquid supplied for each irrigation can be set.

[0034] Step 7: When the valve seat and the valve core are in contact, the through hole is blocked by the valve core. At this time, the valve opening and closing assembly is in a closed state. At this time, the pouring of the branch is completed. The closing of the branch does not affect the operation of the main pipeline and other branches.

[0035] Step 8: The next time you use it, you can reset the rotating propulsion sleeve by pulling the pull ring, mark the scale on the adjustment rope, and control the flow of the branch during this irrigation by controlling the amplitude of pulling the adjustment rope. When the adjustment rope is pulled, the outer sleeve will overcome the elastic force of the U-shaped spring piece and shrink. At this time, the threaded bushing and the external threaded part will be out of thread fit. When no tension is applied to the adjustment rope, the outer sleeve will be reset under the action of the U-shaped spring piece and its own elastic force, and the threaded bushing and the external threaded part will be restored.

[0036] The beneficial effects achieved by the present invention using the above structure are as follows:

[0037] (1) The container seedling raising mechanism can be used to water and fertilize the individually cultivated plants (it can also be fertilized by dissolving the fertilizer in water), which is beneficial for controlling the nutrient distribution of each plant and avoiding the situation where nearby plants compete for nutrients when concentrated cultivation occurs.

[0038] (2) The flow setting control mechanism can independently and accurately control the watering amount for each plant, and can automatically close the branch flow channel where it is located after the watering is completed. This branch closure does not affect the watering of other plants, so the technical effect of automatically completing quantitative watering without manual operation can be achieved.

[0039] (3) Through the cooperation of the rotary push sleeve and the threaded bushing, the rotary push sleeve can gradually approach the quantitative rotation mechanism when it rotates, thereby controlling the gap between the valve seat and the valve core. When the valve seat and the valve core fit together, the entire branch will be closed.

[0040] (4) By means of the separation grooves provided on the outer sleeve, the outer sleeve can be divided into a plurality of independent elastic sheets. Combined with the design of the pulling direction of the adjustment rope, the technical effect of the external threaded portion automatically separating from the threaded bushing when the adjustment rope is pulled and the external threaded portion automatically combining with the threaded bushing when the adjustment rope is loosened can be achieved.

[0041] (5) The thrust generated by the water flowing through the impeller body can drive the rotating propulsion sleeve and the rotary quantitative circulation component to rotate. On the one hand, it can change the axial position of the rotating propulsion sleeve in the channel-type flow control housing in combination with the threaded fit. On the other hand, it can also enable the relative rotation of the rotary quantitative circulation component and the fixed liquid inlet and discharge component, so that the quantitative rotating mechanism can complete the function of quantitative liquid discharge.

[0042] (6) The quantitative rotating mechanism can strictly limit the relationship between the flow rate and the rotation angle by discharging the liquid quantitatively in succession through the rotating sleeve, so that the two parameters "flow rate" and "rotation angle" that were originally affected by multiple factors now have a strict positive proportional relationship, thereby making the relationship "the rotation angle of the rotating propulsion sleeve reflects the liquid flow rate" more stable and controllable.

[0043] (7) The impeller sleeve rotates together with the impeller bracket and the rotating propulsion sleeve driven by the impeller body, but the flow rate through the quantitative rotating mechanism is strictly limited by the impeller sleeve. Therefore, the rotation angle of the impeller quantitative circulation component can actually ignore the influence of error factors such as flow rate, and directly feedback the liquid flow rate through the quantitative rotating mechanism.

[0044] (8) When the wheel sleeve passes through the liquid inlet circular hole, it can be filled with liquid under the action of water pressure and magnetic attraction. When passing through the arc-shaped liquid discharge groove, the liquid in the liquid inlet circular hole will be discharged quantitatively under the action of water pressure and elastic force. Since the amount of liquid discharged from the liquid inlet circular hole each time is roughly equal, the amount of liquid flowing through the quantitative rotating mechanism can be reflected by the rotation angle of the wheel bracket.

[0058] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0059] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0060] like Figure 1 to Figure 11As shown, the present invention proposes a precise fertilization device for cultivating large seedlings of fruit trees in containers, comprising a container seedling cultivation mechanism 1, a flow setting control mechanism 2 and a quantitative rotation mechanism 3. The container seedling cultivation mechanism 1 comprises a main pipeline 4 and a seedling cultivation container assembly 5. The main pipeline 4 is arrayed with branch joints 6 and a tail pipe portion 7.

[0061] The seedling container assembly 5 includes a seedling container body 8, an annular irrigation pipe 9 and a seedling body 10. The end of the channel-type flow control shell 12 is connected to the annular irrigation pipe 9. The inner part of the annular irrigation pipe 9 is evenly distributed with infiltration pipes 11. The annular irrigation pipe 9 is located in the seedling container body 8, and the seedling body 10 is located in the annular irrigation pipe 9.

[0062] The container seedling raising mechanism 1 can be used to water and fertilize the individually cultivated plants (it can also be fertilized by dissolving the fertilizer in water and then watering), which is beneficial to control the nutrient distribution of each plant and avoid the situation where nearby plants compete for nutrients during concentrated cultivation.

[0063] The flow setting control mechanism 2 includes a channel-type flow control housing 12, a threaded fitting component 13, a pull-rope type adjustment component 14, an impeller rotation component 15 and a valve opening and closing component 16. The channel-type flow control housing 12 is arranged on the branch joint 6, the threaded fitting component 13 is arranged in the channel-type flow control housing 12, the pull-rope type adjustment component 14 is arranged on the threaded fitting component 13, the impeller rotation component 15 is snap-fitted in the threaded fitting component 13, and the valve opening and closing component 16 is arranged in the channel-type flow control housing 12.

[0064] The flow setting control mechanism 2 can independently and accurately control the watering amount of each plant, and can automatically close the branch flow channel where it is located after the watering is completed. This branch closure does not affect the watering of other plants, so the technical effect of automatically completing quantitative watering can be achieved without manual operation.

[0065] The threaded mating assembly 13 includes a threaded bushing 17, a rotary propulsion sleeve 18 and a U-shaped spring piece 19. The threaded bushing 17 is fixedly connected to the inner wall of the channel-type flow control housing 12. The rotary propulsion sleeve 18 is rotatably arranged in the channel-type flow control housing 12. One end of the rotary propulsion sleeve 18 is provided with an inner sleeve 26 and an outer sleeve 27. The outer side of the outer sleeve 27 is provided with an external threaded portion 29. The outer sleeve 27 is provided with dividing grooves 28 in an annular manner. The other end of the rotary propulsion sleeve 18 is also provided with guide bosses 51 in an annular manner. The U-shaped spring piece 19 is arranged between the inner sleeve 26 and the outer sleeve 27.

[0066] By cooperating with the rotary propulsion sleeve 18 and the threaded bushing 17, the rotary propulsion sleeve 18 can gradually approach the quantitative rotation mechanism 3 when rotating, thereby controlling the gap between the valve seat 24 and the valve core 25. When the valve seat 24 and the valve core 25 are fitted, the entire branch will be closed.

[0067] The pull-rope adjustment assembly 14 includes an adjustment pull rope 20 and a pull rope sealing ring 21. One end of the adjustment pull rope 20 is evenly distributed with a thin rope portion 30 in a ring shape. The end of the thin rope portion 30 is connected to the outer sleeve 27. The number of the thin rope portions 30 is the same as the number of the dividing grooves 28. A pull ring 31 is provided at the end of the adjustment pull rope 20. The pull rope sealing ring 21 is snap-fitted into the tail pipe portion 7, and the adjustment pull rope 20 is snap-fitted and slidably arranged in the pull rope sealing ring 21.

[0068] By means of the separation groove 28 arranged on the outer sleeve 27, the outer sleeve 27 can be divided into multiple independent elastic sheets. Combined with the design of the pulling direction of the adjustment rope 20, it can achieve the technical effect that the external threaded part 29 is automatically separated from the threaded bushing 17 when the adjustment rope 20 is pulled, and the external threaded part 29 and the threaded bushing 17 are automatically combined when the adjustment rope 20 is loosened.

[0069] The impeller rotating assembly 15 includes a clamping sleeve 22 and an impeller body 23 . The clamping sleeve 22 is clamped on the inner wall of the rotating propulsion sleeve 18 . The impeller body 23 is fixed on the inner wall of the clamping sleeve 22 . A central axis 32 is provided at the center of the impeller body 23 .

[0070] The thrust generated by the water flow passing through the impeller body 23 can drive the rotating propulsion sleeve 18 and the rotary quantitative circulation component 34 to rotate. On the one hand, it can change the axial position of the rotating propulsion sleeve 18 in the channel-type flow control housing 12 in combination with the threaded fit. On the other hand, it can also enable the quantitative rotating mechanism 3 to complete the function of quantitative discharge through the relative rotation of the rotary quantitative circulation component 34 and the fixed liquid inlet and discharge component 35.

[0071] The valve opening and closing assembly 16 includes a valve seat 24 and a valve core 25. The valve seat 24 is engaged in a rotary quantitative circulation assembly 34, and the valve core 25 is engaged in a rotating propulsion sleeve 18. The valve seat 24 is provided with through holes 33 evenly distributed in an annular pattern. When the valve core 25 and the valve seat 24 are in contact, the through holes 33 can be closed.

[0072] The quantitative rotating mechanism 3 includes a rotary quantitative circulation component 34, a fixed liquid inlet and discharge component 35 and a quantitative liquid discharge component 36. The rotary quantitative circulation component 34 is rotatably arranged in the channel type flow control housing 12, the rotary quantitative circulation component 34 is arranged on the threaded matching component 13, the fixed liquid inlet and discharge component 35 is snap-fitted in the channel type flow control housing 12, and the quantitative liquid discharge component 36 is evenly distributed in a ring on the rotary quantitative circulation component 34.

[0073] The quantitative rotating mechanism 3 can strictly limit the relationship between the flow rate and the rotation angle through the successive quantitative discharge of the rotary sleeve 38, so that the two parameters of "flow rate" and "rotation angle" originally affected by multiple factors now have a strict positive proportional relationship, thereby making the relationship of "reflecting the liquid flow rate according to the rotation angle of the rotating propulsion sleeve 18" more stable and controllable.

[0074] The rotary quantitative circulation component 34 includes a rotary bracket 37 and a rotary sleeve 38. The rotary bracket 37 is rotatably arranged in the channel-type flow control housing 12. A mounting frame 44 is provided on the rotary bracket 37. The rotary sleeve 38 is clamped in the mounting frame 44. A plurality of groups of rotary sleeves 38 are evenly distributed in a ring. A guide groove 52 that slides with the guide boss 51 is also provided on the inner wall of the rotary bracket 37. The valve seat 24 is fixedly connected to the rotary bracket 37.

[0075] The impeller sleeve 38 rotates together with the impeller bracket 37 and the rotating propulsion sleeve 18 driven by the impeller body 23, but the flow rate through the quantitative rotating mechanism 3 is strictly limited by the impeller sleeve 38. Therefore, the rotation angle of the impeller quantitative circulation component 34 can actually ignore the influence of error factors such as flow rate, and directly feed back the liquid flow rate through the quantitative rotating mechanism 3.

[0076] The fixed liquid inlet and discharge assembly 35 includes an I-shaped disc bracket 39 and a magnetic ring 40. The I-shaped disc bracket 39 is composed of a first disc 45, a second disc 46 and a connecting column 47. The I-shaped disc bracket 39 is fixedly connected to the inner wall of the channel type flow control housing 12 through the second disc 46. The first disc 45 is provided with a liquid inlet hole 48, and the second disc 46 is provided with an arc-shaped liquid discharge groove 49. The magnetic ring 40 is snap-fitted into the liquid inlet hole 48. The same rotor sleeve 38 is not connected to the liquid inlet hole 48 and the arc-shaped liquid discharge groove 49 at the same time.

[0077] When the wheel sleeve 38 passes through the liquid inlet circular hole 48, it can be filled with liquid under the action of water pressure and magnetic attraction. When passing through the arc-shaped liquid discharge groove 49, the liquid in the liquid inlet circular hole 48 will be quantitatively discharged under the action of water pressure and elastic force. Since the amount of liquid discharged from the liquid inlet circular hole 48 each time is roughly equal, the rotation angle of the wheel bracket 37 can reflect the amount of liquid flowing through the quantitative rotating mechanism 3.

[0078] The quantitative discharge assembly 36 includes an accordion-type hollow bag 41, a diaphragm one-way valve 42 and a discharge spring 43. One end of the accordion-type hollow bag 41 is fixedly connected to the magnetic ring 40, and the other end of the accordion-type hollow bag 41 is provided with a magnetic block 50. The magnetic block 50 slides in the rotor sleeve 38 with the end of the accordion-type hollow bag 41. The diaphragm one-way valve 42 is fixedly connected to one end of the accordion-type hollow bag 41. The diaphragm one-way valve 42 and the magnetic block 50 are located at the same end of the accordion-type hollow bag 41. The discharge spring 43 is arranged between the magnetic block 50 and the end mounting ring of the liquid inlet hole 48.

[0079] When in use, the user first needs to deliver water for irrigation or nutrient solution with dissolved fertilizer through the main pipe 4. When the valve opening and closing component 16 is in the open state, the liquid will flow into the annular irrigation pipe 9 through the channel flow control housing 12, and then diffuse to the root of the seedling body 10 through the infiltration pipe 11;

[0080] When the liquid flows through the impeller body 23, the impact of the liquid on the impeller body 23 can cause the impeller rotating assembly 15 to rotate. The impeller rotating assembly 15 will also cause the rotating propulsion sleeve 18 and the rotary quantitative circulation assembly 34 to rotate together. When the rotating propulsion sleeve 18 rotates, due to the threaded fit between the external threaded portion 29 and the threaded bushing 17, the position of the rotating propulsion sleeve 18 will gradually approach the quantitative rotating mechanism 3, and the distance between the valve seat 24 and the valve core 25 will gradually decrease.

[0081] During the slow rotation of the rotating wheel bracket 37 following the rotating propulsion sleeve 18, since the same rotating wheel sleeve 38 will not be connected with the liquid inlet circular hole 48 and the arc-shaped liquid discharge groove 49 at the same time, when the rotating wheel sleeve 38 is connected with the liquid inlet circular hole 48, the end of the rotating wheel sleeve 38 close to the second disc 46 is in a blocked state. At this time, since the water pressure in the main pipeline 4 is high and the liquid can flow in one direction through the diaphragm one-way valve 42, water will enter the rotating wheel sleeve 38 and compress the air in the accordion-type hollow bag 41;

[0082] As the accordion-type hollow bag 41 is compressed, the length of the accordion-type hollow bag 41 is shortened, and the distance between the magnetic block 50 and the magnetic ring 40 gradually approaches. During this movement, the water pressure and the magnetic attraction force are superimposed on each other, the water pressure is dominant in the front section, and the magnetic attraction force is dominant in the rear section, until the magnetic block 50 moves to the extreme position;

[0083] As the wheel bracket 37 continues to rotate, when the wheel sleeve 38 is no longer connected to the liquid inlet circular hole 48 but is connected to the arc-shaped drainage groove 49, after the magnetic attraction is lost, the liquid in the wheel sleeve 38 will be discharged through the arc-shaped drainage groove 49 under the combined action of the air pressure in the accordion-type hollow bag 41 and the elastic force of the drainage spring 43.

[0084] When the input water pressure of the main pipeline 4 is stable, the amount of liquid sucked in and discharged by the impeller sleeve 38 each time is also stable. Therefore, the flow through the branch is positively correlated with the rotation angle of the impeller bracket 37. By setting the number of rotations of the rotating propulsion sleeve 18, the amount of liquid supplied for each irrigation can be set.

[0085] When the valve seat 24 and the valve core 25 are in contact, the through hole 33 is blocked by the valve core 25. At this time, the valve opening and closing assembly 16 is in a closed state. At this time, the irrigation of the branch is completed. The closing of the branch does not affect the operation of the main pipeline 4 and other branches.

[0086] When used next time, the rotating propulsion sleeve 18 can be reset by pulling the pull ring 31, and the scale can be marked on the adjustment rope 20. The flow rate of the branch during this irrigation can be controlled by controlling the amplitude of pulling the adjustment rope 20. When the adjustment rope 20 is pulled, the outer sleeve 27 will overcome the elastic contraction of the U-shaped spring piece 19. At this time, the threaded bushing 17 and the external threaded part 29 are disengaged from the threaded fit. When no tension is applied to the adjustment rope 20, the outer sleeve 27 will be reset under the action of the U-shaped spring piece 19 and its own elastic force, and the threaded fit of the threaded bushing 17 and the external threaded part 29 will be restored.

7. The method for using the precise fertilization device for cultivating large seedlings in fruit containers according to claim 6, characterized in that: The steps include: Step 1: Water or nutrient solution containing dissolved fertilizers is transported through the main pipeline. When the valve opening and closing assembly is in the open state, the liquid flows into the annular irrigation pipe through the channel flow control housing, and then diffuses to the root area around the seedling body through the infiltration pipe; Step 2: When the liquid flows through the impeller body, the impact of the liquid on the impeller body can cause the impeller rotating assembly to rotate. The impeller rotating assembly will also cause the rotating propulsion sleeve and the rotary quantitative circulation assembly to rotate together. When the rotating propulsion sleeve rotates, due to the thread matching between the external thread part and the threaded bushing, the position of the rotating propulsion sleeve will gradually approach the quantitative rotating mechanism, and the distance between the valve seat and the valve core will gradually decrease; Step 3: As the runner bracket slowly rotates along with the rotating propulsion sleeve, the same runner sleeve will not be connected to the liquid inlet circular hole and the arc-shaped liquid discharge groove at the same time. Therefore, when the runner sleeve is connected to the liquid inlet circular hole, the end of the runner sleeve close to the second disc is blocked. At this time, since the water pressure in the main pipeline is high and the liquid can flow in one direction through the diaphragm one-way valve, water will enter the runner sleeve and compress the air in the accordion-type hollow bag. Step 4: As the accordion-type hollow air bag is compressed, the length of the accordion-type hollow air bag is shortened, and the distance between the magnetic block and the magnetic ring gradually approaches. During this movement, the water pressure and the magnetic attraction force are superimposed on each other, with the water pressure dominating in the front section and the magnetic attraction force dominating in the back section until the magnetic block moves to the limit position; Step 5: As the wheel bracket continues to rotate, when the wheel sleeve is no longer connected to the liquid inlet hole but connected to the arc-shaped liquid discharge groove, the magnetic attraction is lost, and the liquid in the wheel sleeve is discharged through the arc-shaped liquid discharge groove under the combined action of the air pressure in the accordion-type air bag and the elastic force of the liquid discharge spring; Step 6: When the input water pressure of the main pipeline is stable, the amount of liquid sucked in and discharged by the runner sleeve each time is also stable. Therefore, the flow through the branch is positively correlated with the rotation angle of the runner bracket. By setting the number of rotations of the rotating propulsion sleeve, the amount of liquid supplied for each irrigation can be set; Step 7: When the valve seat and the valve core are in contact, the through hole is blocked by the valve core. At this time, the valve opening and closing assembly is in a closed state. At this time, the pouring of the branch is completed. The closing of the branch does not affect the work of the main pipeline and other branches. Step 8: The next time you use it, you can reset the rotating propulsion sleeve by pulling the pull ring, mark the scale on the adjustment rope, and control the flow of the branch during this irrigation by controlling the amplitude of pulling the adjustment rope. When the adjustment rope is pulled, the outer sleeve will overcome the elastic force of the U-shaped spring piece and shrink. At this time, the threaded bushing and the external threaded part will be out of thread fit. When no tension is applied to the adjustment rope, the outer sleeve will be reset under the action of the U-shaped spring piece and its own elastic force, and the threaded bushing and the external threaded part will be restored.
