Description

Technical Field

[0001] The present invention relates to the technical field of planting and fertilization, and in particular to a long root induction fertilization device with adjustable depth in the Paeonia lactiflora planting area. Background Art

[0002] Paeonia lactiflora is an important medicinal plant, and its root system has obvious stage characteristics in the growth process for the demand of fertilizers. In different growth stages, the root distribution depth of Paeonia lactiflora will be different, so the fertilizer absorption capacity and the required depth of fertilizers will also change accordingly. Most traditional fertilization devices can only apply fertilizers at a fixed depth and cannot dynamically adjust the fertilization depth according to the growth stage and root distribution of Paeonia lactiflora, resulting in poor fertilization effects. The specific problems are as follows:

[0003] Limitations of fixed fertilization depth: Traditional fertilization devices usually can only apply fertilizers at a single depth and cannot meet the demand of the Paeonia lactiflora root system for fertilizer depth in different growth stages. For example, in the initial growth stage of Paeonia lactiflora, the roots are relatively shallow and require a shallower fertilization depth; while in the later growth stage, the roots gradually penetrate deeper into the soil and require a deeper fertilization depth. The fertilization method with a fixed depth cannot adapt to this change, resulting in fertilizers not being accurately applied to the root system, causing fertilizer waste and poor fertilization effects.

[0004] Fertilizer loss and waste: Due to the inability to dynamically adjust the fertilization depth according to the actual demand of the Paeonia lactiflora root system, traditional fertilization devices easily lead to uneven distribution of fertilizers in the soil, and some fertilizers may be lost without being absorbed by the root system, not only wasting fertilizer resources but also potentially causing environmental pollution.

[0005] Restricted root growth: The lack of a device for dynamically adjusting the fertilization depth cannot effectively promote the growth and development of the Paeonia lactiflora root system. During the growth process, the roots may grow slowly due to insufficient nutrients, affecting the final yield and quality of Paeonia lactiflora.

[0006] In summary, the existing fertilization devices have many deficiencies in the planting of Paeonia lactiflora and cannot meet the dynamic demand of the Paeonia lactiflora root system for fertilizer depth in different growth stages. There is an urgent need for a device that can dynamically adjust the fertilization depth according to the growth stage of Paeonia lactiflora to improve the fertilization effect and promote the growth and development of the Paeonia lactiflora root system. Summary of the Invention

[0007] (1) Technical problems to be solved

[0008] In view of the deficiencies of the prior art, the present invention provides a long root induction fertilization device with adjustable depth in the Paeonia lactiflora planting area. Through the setting of the control component, the feeding ports of the fertilizer export components at different positions can be controlled to open and close, so that the liquid fertilizer inside the hollow sleeve is exported through different fertilizer export components, forming fertilization induction work at different depths. By adjusting the fertilization depth, the fertilizer can directly act on the roots of Paeonia lactiflora, reducing the loss and waste of fertilizer. The fertilization depth can be dynamically adjusted according to the growth stage of Paeonia lactiflora, which can better meet the fertilizer requirements of the roots of Paeonia lactiflora, promote the growth and development of the roots, and solve the problem that most traditional fertilization devices can only fertilize at a fixed depth and cannot dynamically adjust the fertilization depth according to the growth stage and root distribution of Paeonia lactiflora.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0044] Embodiment 1:

[0045] Refer to the attached Figures 1 to 5 and Figure 10 For the long root induction fertilization device with adjustable depth in the red peony planting area, it includes a conveying main pipe 1 and several fertilization mechanisms. The several fertilization mechanisms are respectively arranged at the centers of four groups of red peony planting positions. The conveying main pipe 1 is used to convey liquid fertilizer to the several fertilization mechanisms.

[0046] A conveying pump is installed at the input end of the conveying main pipe 1 to convey the prepared liquid fertilizer into the conveying main pipe 1, and the prepared liquid fertilizer is conveyed through the conveying main pipe 1 to the several fertilization mechanisms for fertilization induction work.

[0047] The fertilization mechanism includes a hollow sleeve 2 inserted into the soil, several fertilizer outlet parts 4 and a control component 5. The top of the hollow sleeve 2 is connected to the conveying main pipe 1 through a drainage pipe 3.

[0048] A flow control valve is installed on the drainage pipe 3 to control the amount of liquid fertilizer entering the inside of the hollow sleeve 2.

[0049] The length of the hollow sleeve 2 is greater than or equal to the total length of the growth of the red peony roots, which is convenient for fully improving the growth effect of the red peony root part and improving the subsequent utilization effect of the red peony roots.

[0050] By connecting the top of the hollow sleeve 2 to the conveying main pipe 1 through the drainage pipe 3, it is convenient to convey the prepared liquid fertilizer inside the conveying main pipe 1 into the hollow sleeve 2.

[0051] Several groups of fertilizer outlet parts 4 are all arranged on the outer surface of the hollow sleeve 2, and the fertilizer outlet parts 4 are used to discharge the liquid fertilizer inside the hollow sleeve 2 into the soil.

[0052] Through the setting of the fertilizer outlet parts 4, it is used to export the liquid fertilizer inside the hollow sleeve 2 to form a fertilization induction work. By setting multiple fertilizer outlet parts 4, the fertilization induction work at different depths can be satisfied.

[0053] The control component 5 is used to control the opening and closing of the material guiding ports of the fertilizer discharging components 4 at different positions;

[0054] By setting the control component 5, the opening and closing of the material guiding ports of the fertilizer discharging components 4 at different positions can be controlled. Then, the liquid fertilizer inside the hollow sleeve 2 is discharged through different fertilizer discharging components 4, forming fertilization induction work at different depths. By adjusting the fertilization depth, the fertilizer can directly act on the roots of Paeonia lactiflora, reducing the loss and waste of fertilizer. The fertilization depth can be dynamically adjusted according to the growth stage of Paeonia lactiflora, which can better meet the fertilizer requirements of the roots of Paeonia lactiflora and promote the growth and development of the roots.

Through the up and down movement of the piston plate 51, the conical blocking blocks 43 of the fertilizer discharging components 4 at different positions can be contacted, causing the conical blocking blocks 43 to contract. Then, the connecting pipes 42 are internally connected to the annular sleeve frame 41, forming liquid fertilizer conveying work. On the contrary, when the piston plate 51 loses contact with the conical blocking blocks 43, the elastically installed conical blocking blocks 43 can automatically reset to form a blocking work, thus realizing the adjustment work of fertilization at different depths.

[0060] Refer to the appendix Figure 5 As shown in the figure, a plurality of discharge ports 44 are formed on the outer surface of the annular sleeve frame 41, and a filter membrane 45 is arranged among the plurality of discharge ports 44;

[0063] Through the opening of the conical holes, it is convenient for the connecting pipes 42 to communicate with the inside of the hollow sleeve 2, and then it is convenient for the liquid fertilizer inside the hollow sleeve 2 to enter the connecting pipes 42 and finally enter the annular sleeve frame 41 for fertilization work;

[0064] Through the arrangement of the conical plug block 43, it is used to block the conical holes, which can prevent the liquid fertilizer inside the hollow sleeve 2 from entering. Through the arrangement of the elastic member 46, it is used to elastically squeeze the conical plug block 43 to improve the stability and sealing performance of the conical plug block 43 for blocking the conical holes;

[0068] By making the toggle bars 53 inclined, so that when the conical plug block 43 is telescopically driven through different positions of the inclined surfaces of the toggle bars 53, different telescopic distance controls can be formed, and then the flow control work can be formed to prevent the flow rate from being too large, resulting in excessive fertilizer supplementation, and to prevent the flow rate from being too small, resulting in insufficient fertilizer supply; The inclined setting of the toggle bars 53 is specifically referred to in the appendix Figure 4 It can be understood.

[0069] Refer to the appendix Figures 1 to 3, the control component 5 includes a threaded rod 54 rotatably connected inside the hollow sleeve 2. The threaded rod 54 is threadedly connected to the piston plate 51, and the motor 52 is used to rotationally drive the threaded rod 54;

[0070] By rotating the threaded rod 54, the piston plate 51 can be driven to move up and down. The up and down movement of the piston plate 51 can drive the telescopic movement of the conical plug 43 in the fertilizer outlet 4, forming the self-opening operation of the conical hole;

[0071] Here, the motor 52 is fixedly connected to the driving end of the threaded rod 54, used to drive the threaded rod 54 to rotate forward and backward, forming the driving operation of the piston plate 51 up and down.

[0078] One-way valves are provided on several pneumatic tubes 7 and several connecting tubes 6, which facilitates one-way control of the pneumatic tubes 7 and the connecting tubes 6, prevents the gas inside the connecting tubes 6 from entering the conveying main pipe 1, and prevents the liquid fertilizer inside the connecting tubes 6 from entering the pneumatic tubes 7, thereby improving the orderliness of pneumatic conveying.

[0079] Embodiment 3: Different from Embodiment 1;

[0080] Refer to the appendix Figure 8 and Figure 9 , soil loosening components are provided on the hollow sleeves 2 in several fertilizing mechanisms;

[0081] Through the setting of the soil loosening components, the soil in the fertilizing area is loosened, which not only improves the air permeability of the root part of Paeonia lactiflora, but also improves the penetration effect of its liquid fertilizer. It not only further improves its fertilizing performance, but also effectively prevents the problem that due to the large soil hardness, when applying underground fertilizer, the liquid cannot be quickly exported, resulting in the liquid fertilizer staying in the hollow sleeve 2 for a long time and the roots not getting fertilizer nutrition;

[0082] The soil loosening components include a toothed disc 9 fixed on the outer surface of the top of the threaded rod 54, and several rotating shafts 10 rotatably connected to the outer surface of the hollow sleeve 2 through brackets.

[0083] By meshing several gears 13 with the toothed disc 9, it is convenient to drive several gears 13 to rotate synchronously through the rotation of the toothed disc 9. Then, the rotating shafts 10 can be driven to rotate through the universal shaft 12, and finally several auger discs 11 can be driven to rotate. By the rotation of the several auger discs 11, the soil in the fertilizing area can be agitated, making the hard soil start to loosen, thereby improving the penetration effect of the liquid fertilizer and the air permeability of the root part of Paeonia lactiflora;

[0084] By fixedly connecting the toothed disc 9 with the threaded rod 54, it is convenient to drive the soil loosening components synchronously when controlling the fertilizer outlet parts 4 at different positions through the threaded rod 54, forming an automatic soil loosening operation.
