Description

Technical Field

[0001] The invention discloses a guava fertilizing device and a fertilizing method, and belongs to the technical field of guava cultivation. Background Art

[0002] Guava is a tree of the Myrtaceae family, up to 13 meters tall; the bark is smooth, gray, and exfoliates in sheets; the young branches are ribbed and hairy, the leaves are leathery, oblong to elliptic, acute or obtuse at the apex, nearly rounded at the base, slightly rough on the upper side, hairy on the lower side, the lateral veins are often sunken, and the reticulate veins are obvious; the petiole is 5 mm long, the flowers are solitary or 2-3 flowers are arranged in cymes; the calyx tube is bell-shaped and hairy, and the calyx cap is irregularly split; the petals are white; the stamens are 6-9 mm long; the ovary is inferior and fused to the calyx, the style is the same length as the stamens, the berry is spherical, ovoid or pear-shaped, with persistent sepals at the top, the flesh is white and yellow, the placenta is hypertrophic, fleshy, light red, and there are many seeds. The existing cultivation and fertilization methods for guava or other fruit trees mostly use a vehicle-mounted mobile device. At one or several locations around the roots of the tree, a drilling device is used to drill holes of a certain depth in the soil, and then liquid fertilizer is injected into the holes to complete the fertilization process. However, since the holes are drilled at fixed points, the soil around the holes is squeezed during the drilling process, resulting in a longer time for the liquid fertilizer to penetrate into the soil. When too much liquid fertilizer is applied, it will overflow from the hole. Since the surface soil is in a solidified block shape, it cannot penetrate into the soil of the root system, resulting in loss and waste. At the same time, the range of drilling fertilization is relatively limited, so the root growth of other unfertilized locations becomes sluggish. Summary of the Invention

[0008] Preferably, the fertilizing assembly includes a movable rod, a sealing cone, a spring, and a feed pipe. The fixed shaft has a liquid storage cavity. The movable rod is slidably arranged inside the fixed shaft. The upper end of the movable rod extends to the outside of the fixed shaft, and the lower end of the movable rod is fixedly connected to the sealing cone. The spring is sleeved outside the movable rod and applies a force to block the liquid storage cavity to the sealing cone. A communication hole communicating with the liquid storage cavity is also provided at the upper end of the movable rod. The other end of the communication hole is connected to the feed pipe. The fixed frame has a second arc-shaped groove for the feed pipe to pass through.

[0009] Preferably, there are two sets of power assemblies. The power assembly includes a screw rod, a third gear, a fourth gear, and a second motor. The second motor is fixed on the fixed frame. The third gear is fixed on the output shaft of the second motor. One end of the screw rod is fixed on the movable frame, and the other end of the screw rod penetrates through the fixed frame. A limiting block for installing the fourth gear is provided on the fixed frame. The limiting block is rotatably connected to the fourth gear, and the limiting block is fixedly connected to the fixed frame by bolts. The fourth gear is threadedly connected to the screw rod.

[0010] Preferably, there are four sets of soil-breaking assemblies, and the rotation angle of the soil-breaking assemblies around the center of the movable frame is 60° - 80°.

[0011] Preferably, the fixed frame, the movable frame, the first toothed ring, and the second toothed ring are all detachable structures assembled in half.

[0012] A guava fertilizing method includes the following steps:

[0013] S1: Install the fertilizing device on the outside of the bottom trunk of the guava, and connect the feed pipe to an external liquid fertilizer supply device;

[0014] S2: Configure the liquid fertilizer. The components of the liquid fertilizer include: 10 parts of urea, 6 parts of diammonium phosphate, 8 parts of potassium sulfate, 25 parts of potassium humate, 8 parts of magnesium source, 6 parts of EM bacterial liquid, 3 parts of auxin, and 8 parts of superphosphate. And the supply device transports the liquid fertilizer to the liquid storage cavity through the feed pipe;

[0015] S3: Driven by the driving component, the soil-breaking component rotates back and forth by a preset angle with the center of the movable frame as the rotation point. During this process, the soil-breaking component relies on the transmission component to achieve self-rotation. At the same time, the power component drives the movable frame and the soil-breaking component to descend, and the soil-breaking component is used to break the solidified soil around the roots of the guava tree;

[0016] S4: After the soil is broken, the power component drives the movable frame and the soil-breaking component to rise. After the upper end of the movable rod touches the fixed frame, the sealing cone no longer blocks the liquid outlet cavity, so that the liquid fertilizer flows out. At the same time, the driving component continues to drive the soil-breaking component to rotate to ensure that the liquid fertilizer is evenly sprinkled on the surface of the broken soil and finally penetrates into the soil around the guava roots.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. By setting the fixed frame, movable frame, soil-breaking mechanism and fertilizing component, the overall structure is fixedly arranged on the outside of the bottom trunk of the guava tree. The trunk passes through the centers of the movable frame and the fixed frame. By controlling the operation of the first motor and the second motor through an external liquid fertilizer supply device and a remote switch, automatic regular and quantitative fertilization can be achieved.

[0019] 2. By setting the soil-breaking component, driving component, transmission component and power component, the soil-breaking component can rotate back and forth by a certain angle with the center of the movable frame as the rotation point under the drive of the driving component, and the transmission component can make the soil-breaking component rotate self. In this way, the caked and solidified soil on the surface around the guava roots can be broken within a certain range. The power component can control the depth of soil breaking by the soil-breaking component. After the soil is broken, the fertilizing component sprays liquid fertilizer on the surface of the soil. The liquid fertilizer can quickly penetrate into the soil around the guava roots, and the liquid fertilizer will not overflow. At the same time, due to the large movement range of the fertilizing component, the growth range of the guava root system tissue can be expanded after spraying the liquid fertilizer.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a 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 those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] As Figures 1-7 shown, a guava fertilizing device includes a fixing frame 3, a movable frame 8, a soil-breaking mechanism and a fertilizing component 5. Both the fixing frame 3 and the movable frame 8 are circular ring structures, and both are suspended above the guava root system. The soil-breaking mechanism includes a soil-breaking component 1 and a driving component 9. There are at least three groups of soil-breaking components 1, which are distributed at equal angles around the center of the movable frame 8. The driving component 9 is installed on the movable frame 8 and is used to drive the soil-breaking component 1 to rotate back and forth by a preset angle on the movable frame 8. A transmission component for allowing the soil-breaking component 1 to rotate self is provided on the movable frame 8. The fertilizing component 5 is installed on the soil-breaking component 1 and is used to control the liquid fertilizer to flow out from the lower end of the soil-breaking component 1. A power component 4 for controlling the lifting of the movable frame 8 is provided on the fixing frame 3.

[0030] The soil-breaking component 1 includes a fixed shaft 11 and spiral ridges 10. The spiral ridges 10 are located on the outer side of the fixed shaft 11. A first arc-shaped groove 2 for the rotation of the fixed shaft 11 is provided on the movable frame 8. The driving component 9 includes a first motor 16, a first gear 15 and a first toothed ring 14. An annular groove is provided on the inner side of the movable frame 8. The first toothed ring 14 is rotatably installed in the annular groove. The first motor 16 is fixed on the movable frame 8. The first gear 15 is fixed on the output shaft of the first motor 16 and meshes with the first toothed ring 14. The fixed shaft 11 is rotatably connected to the first toothed ring 14. The transmission component includes a second toothed ring 12 and a second gear 13. The second toothed ring 12 is fixedly connected to the movable frame 8. The second gear 13 is fixed on the fixed shaft 11 and meshes with the second toothed ring 12. When the first motor 16 drives the first gear 15 to rotate, the first toothed ring 14 is driven by the first gear 15 to rotate. In this way, the fixed shaft 11 can be driven to rotate with the center of the movable frame 8 as the rotation point. When the first motor 16 rotates forward or backward, the soil-breaking component 1 can rotate back and forth by a preset angle. During this process, the second gear 13 moves synchronously with the fixed shaft 11. When the second gear 13 meshes with the second toothed ring 12, the fixed shaft 11 is driven to rotate by the second gear 13. In this way, relying on the spiral ridges 10 on the outer side of the fixed shaft 11, the caked soil on the surface around the roots of the guava tree can be broken, thus preparing for spraying liquid fertilizer on the surface of the broken soil later.

[0031] The fertilizing component 5 includes a movable rod 19, a sealing cone 27, a spring 18 and a feed pipe 17. The fixed shaft 11 has a liquid storage cavity 20. The movable rod 19 is slidably arranged inside the fixed shaft 11. The upper end of the movable rod 19 extends to the outside of the fixed shaft 11, and the lower end of the movable rod 19 is fixedly connected to the sealing cone 27. The spring 18 is sleeved outside the movable rod 19 and applies a force to block the liquid storage cavity 20 to the sealing cone 27. A circulation hole 26 communicating with the liquid storage cavity 20 is also arranged at the upper end of the movable rod 19. The other end of the circulation hole 26 is connected to the feed pipe 17. The fixed frame 3 has a second arc-shaped groove 7 for the feed pipe 17 to pass through. After the soil-breaking component 1 and the fertilizing component 5 are installed, the liquid storage cavity 20 in the fixed shaft 11 is blocked by the spring 18 and the sealing cone 27, so that the liquid fertilizer conveyed by the external supply device enters the liquid storage cavity 20 through the feed pipe 17 and the circulation hole 26. When breaking the soil, the soil cannot enter between the sealing cone 27 and the fixed shaft 11, so that the flow of the liquid fertilizer will not be blocked during the fertilizing process. When the soil-breaking component 1 breaks the caked soil around the guava tree root, the power component 4 drives the movable frame 8 to move upward until the movable rod 19 abuts against the fixed frame 3 and compresses the spring 18, so that the movable rod 19 drives the sealing cone 27 to move downward. In this way, the liquid storage cavity 20 is opened, and the liquid fertilizer is sprayed on the surface of the broken soil along the sealing cone 27. Since both the upper and lower ends of the sealing cone 27 have conical surfaces, when the liquid fertilizer flows on its surface, the spraying range of the liquid fertilizer can be effectively controlled and will not flow to the surface of other caked soil, avoiding the loss and waste of the liquid fertilizer.

[0032] There are two sets of power components 4, and the power component 4 includes a screw rod 23, a third gear 24, a fourth gear 21 and a second motor 25. The second motor 25 is fixed on the fixed frame 3. The third gear 24 is fixed on the output shaft of the second motor 25. One end of the screw rod 23 is fixed on the movable frame 8, and the other end of the screw rod 23 penetrates through the fixed frame 3. A limit block 22 for installing the fourth gear 21 is arranged on the fixed frame 3. The limit block 22 is rotatably connected to the fourth gear 21, and the limit block 22 is fixedly connected to the fixed frame 3 by bolts. The fourth gear 21 is threadedly connected to the screw rod 23. The movable frame 8 also has a guide rod 6 slidably arranged on the movable frame 8. When the second motor 25 drives the third gear 24 to rotate, the third gear 24 can drive the fourth gear 21 to rotate. Since the fourth gear 21 is limited by the limit block 22 and the fixed frame 3 to move vertically, it can only rotate. And one end of the screw rod 23 is connected to the movable frame 8, and the movable frame 8 cannot rotate under the limiting action of the two screw rods 23 and the two guide rods 6. Therefore, when the fourth gear 21 rotates, it can drive the screw rod 23 and the movable frame 8 to move vertically. In this way, when the movable frame 8 descends, the depth of soil breaking can be controlled, and when the fourth gear 21 drives the screw rod 23 and the movable frame 8 to rise, the liquid fertilizer can be sprayed on the surface of the broken soil.

[0033] There are four sets of soil-breaking components 1, and the angle of rotation of the soil-breaking components 1 with the center of the movable frame 8 as the rotation point is 60° - 80°. The four sets of soil-breaking components 1 are driven by the same driving component 9, and can simultaneously break the caked soil on the surface around the roots of guava trees. Moreover, the rotation range of the four sets of soil-breaking components 1 is large, which increases the range of soil breaking and the spraying range of liquid fertilizer. This can promote the growth of the root tissue of guava trees and is beneficial to promoting the fruiting of guava. The fixed frame 3, the movable frame 8, the first gear ring 14, and the second gear ring 12 are all detachable structures assembled in half. With the disassembly and assembly structure, the assembly structures are connected by connecting blocks, which can facilitate the installation of the entire fertilization device around the guava tree trunk. The fixed frame 3 is fixed by several support rods. By controlling the operation of the first motor 16, the second motor 25, and the external liquid fertilizer supply device, automatic regular and quantitative fertilization can be achieved.

[0034] A guava fertilization method includes the following steps:

[0035] S1: Install the fertilization device on the outside of the bottom trunk of the guava tree, and connect the feed pipe 17 to the external liquid fertilizer supply device;

[0036] S2: Configure the liquid fertilizer. The components of the liquid fertilizer include: 10 parts of urea, 6 parts of diammonium phosphate, 8 parts of potassium sulfate, 25 parts of potassium humate, 8 parts of magnesium source, 6 parts of EM bacterial liquid, 3 parts of auxin, and 8 parts of superphosphate. And the supply device transports the liquid fertilizer through the feed pipe 17 to the liquid storage cavity 20;

[0037] S3: The driving component 9 drives the soil-breaking component 1 to rotate back and forth by a preset angle with the center of the movable frame 8 as the rotation point. During this process, the soil-breaking component 1 realizes self-rotation by relying on the transmission component. At the same time, the power component 4 drives the movable frame 8 and the soil-breaking component 1 to descend, and relies on the soil-breaking component 1 to break the solidified soil around the roots of the guava tree;

[0038] S4: After the soil is broken, the power component 4 drives the movable frame 8 and the soil-breaking component 1 to rise. After the upper end of the movable rod 19 touches the fixed frame 3, the sealing cone 27 no longer blocks the liquid outlet cavity, so that the liquid fertilizer flows out. At the same time, the driving component 9 continues to drive the soil-breaking component 1 to rotate to ensure that the liquid fertilizer is evenly sprinkled on the surface of the broken soil and finally penetrates into the soil of the guava root system.
