Description

Technical Field

[0001] The present invention relates to the technical field of rubber trees, and particularly relates to an automatic fertilization device and method for natural rubber planting. Background Art

[0002] The automatic fertilization device for natural rubber planting is one of the important applications of precision agriculture technology in rubber tree planting in recent years. Its core goal is to achieve precision, high efficiency, and environmental protection of fertilization through intelligent and automated means.

[0003] For example, the Chinese patent with the publication number CN220935641U discloses a fertilization device, including an installation structure. A moving structure is fixedly installed at the bottom of the installation structure, a rotating structure is fixedly installed at the top of the installation structure, a stirring structure is fixedly installed at the bottom of the rotating structure, and a spraying structure is fixedly installed at the top of the installation structure; the rotating structure includes a cover plate fixedly installed at the top of the barrel body, a feed hopper is fixedly installed at the top of the cover plate, a first motor is fixedly installed at the top of the cover plate, a first gear is fixedly installed at the top of the first motor, a second gear is meshed and installed at the rear end of the first gear, and a rotating pipe is fixedly installed through the top of the second gear. In the improved fertilization device, the rotating structure and the stirring structure are adopted, which can make the solid fertilizer and water dissolve and mix more thoroughly. The shell, the second motor screw rod, and the threaded slider are adopted to adjust the spraying height.

[0004] However, there are still some deficiencies in the above fertilization device during actual use:

[0005] 1. First of all, in the above-mentioned prior art, the fertilization device uses the spraying method for fertilization and can adjust the spraying height to achieve the fertilization operation; however, it should be noted that the amount of fertilization is fixed and cannot automatically adjust the fertilization amount according to the size or thickness of the vegetation. Different sizes of vegetation require different amounts of fertilizer. Smaller vegetation requires less fertilizer, and larger vegetation requires more fertilizer. Therefore, fixed-dose fertilization will cause a large amount of fertilizer waste.

[0006] 2. Secondly, the prior art uses a spray head to fertilize the product. However, it should be noted that when fertilizing with a spray head, the fertilizer is only sprayed near the vegetation and cannot be evenly spread around the vegetation; over time, the roots of the vegetation will grow towards the soil where the fertilizer is located; this not only affects the growth of the vegetation but also causes the fertilizer to accumulate together and cannot be fully absorbed and utilized by the vegetation.

[0007] Therefore, under the viewpoints stated above, there is still room for improvement in the existing fertilization device. Summary of the Invention

[0008] To solve the above problems, the present invention provides an automatic fertilization device and method for natural rubber planting, adopting the following technical solutions:

The first bevel gear is meshed with a second bevel gear, and a first shaft is provided on the second bevel gear.

[0019] A second shaft rotates on the outer wall of the control block, and a first belt is provided between the first shaft and the second shaft.

[0020] Preferably, a telescopic column is installed on the middle gear closer to the control block among the two middle gears in the fertilizing pipeline.

Detailed implementation manners

[0052] The following is further detailed description in conjunction with Figures 1 - 18 this application.

[0053] The embodiment of this application discloses an automatic fertilizer application device and method for natural rubber planting; the automatic fertilizer application device for natural rubber planting is mainly applied in the process of precise and efficient fertilizer application for rubber trees, which not only improves the fertilizer application efficiency but also reduces the cost consumption.

[0054] First of all, in the above-mentioned prior art, there are two ways to apply fertilizer to rubber trees: one is to directly send the fertilizer into the soil so that the fertilizer can be close to the roots of the rubber trees for the rubber trees to absorb. The other is to scatter the fertilizer near the roots of the rubber trees for the rubber trees to absorb by themselves. Among them, the first fertilizer application method is more complicated, while the second fertilizer application method is not only simple but also can ensure the precision of fertilizer application.

[0055] In the prior art, the traditional fertilizer application device scatters the fertilizer near the roots of the trees by spraying for the trees to absorb. However, it should be noted that the amount of fertilizer applied is fixed and cannot automatically adjust the amount of fertilizer applied according to the size or thickness of the trees. Different-sized trees require different amounts of fertilizer. For example, smaller trees require less fertilizer, so less fertilizer can be scattered; larger vegetation requires more fertilizer, so more fertilizer can be scattered. Applying a fixed amount of fertilizer to them will cause a large amount of fertilizer to be obtained by some smaller-sized trees, resulting in a large waste of fertilizer.

[0056] Secondly, the existing technology cannot spread fertilizer evenly around trees; over time, the roots of vegetation will grow towards the soil where the fertilizer is located; not only will the fertilizer accumulate around the tree trunks and absorb moisture from the soil, causing root water shortage, thereby causing root damage and growth stunting, but the fertilizer accumulation will also cause the concentration of certain nutrients in the soil to be too high, while other nutrients are insufficient, destroying the nutritional balance of the soil.

[0057] Furthermore, fertilizer accumulation attracts mosquitoes, mold and pests, which may burrow into the bark and spread disease or directly attack the trunk.

[0058] Therefore, the present application proposes an automatic fertilization device for natural rubber planting to solve the above problems.

[0059] Embodiment 1:

[0060] Reference Figure 1 and Figure 2 As shown, an automatic fertilization device for natural rubber planting includes a mobile control vehicle 1, which is arranged in a rubber tree planting area to cope with different terrains.

[0061] It should be noted that the control vehicle 1 is an existing known structure, and it has a variety of ways, one of which is to automatically control its movement through a program, and the other is that an operator controls its movement. Rubber trees are usually grown on flat or slightly inclined terrain, which is conducive to drainage and preventing soil erosion, and can also be conducive to the growth of rubber trees and the raising of latex production.

[0062] The storage tank 2 for storing fertilizer is symmetrically arranged on the control vehicle 1. A known pump body is arranged in the storage tank 2, and the fertilizer in the storage tank 2 is transported outward along the fertilizer application pipeline 34 by the power of the pump body. The pressure of the pump body is constant, and the amount of fertilizer transported per unit time is also stable.

[0063] The two groups of storage boxes 2 are mainly used to store materials required for fertilizing rubber trees, ensuring that the control vehicle 1 can effectively ensure the continuity of fertilization when moving. Because the rubber planting area generally has a large site, a certain amount of fertilizer is carried to ensure the long-term operation of fertilizing rubber trees, avoiding the decrease of fertilization efficiency caused by frequent transportation of fertilizers.

[0064] See also Figure 2 and Figure 3As shown, the automatic fertilizer applicator 3 automatically fertilizes rubber trees. The automatic fertilizer applicator 3 includes a vertical frame 30 installed on the top of the control vehicle 1. A fixed bracket 31 is slidably arranged on the vertical frame 30. Two groups of first control rods 32 distributed in a V-shaped structure are symmetrically arranged on the fixed bracket 31. At the ends of the two groups of first control rods 32 away from the fixed bracket 31, second control rods 33 are hinged. Fertilizer pipelines 34 are clamped at the bottoms of the two groups of first control rods 32 and second control rods 33. One side of the fertilizer pipeline 34 is connected to the storage tank 2.

[0065] It should be noted that the fertilizer pipeline 34 is clamped at the bottoms of the first control rod 32 and the second control rod 33 by a buckle. When the first control rod 32 and the second control rod 33 move, the fertilizer pipeline 34 can be controlled to move synchronously, and the moving trajectories of the two are always the same.

[0066] Secondly, the fertilizer pipeline 34 is composed of two fixed pipelines 344 and a hose 345. The hose 345 is integrally arranged on the side where the two fixed pipelines 344 are close to each other. The hose 345 is made of rubber and can be telescoped.

[0067] Refer to Figure 4 As shown, it is a schematic structural diagram of the structure for controlling the telescoping of the fertilizer pipeline 34 in this application; specifically, a telescopic hydraulic cylinder 9 is also installed on the fixed bracket 31. The output end of the telescopic hydraulic cylinder 9 is connected to the fixed bracket 31 and controls the fixed bracket 31 to move along the length direction of the control vehicle 1.

[0068] During specific implementation, first, drive the control vehicle 1 to move to the designated area in the rubber planting area, then start the telescopic hydraulic cylinder 9. The output end of the telescopic hydraulic cylinder 9 controls the fixed bracket 31 to extend towards the trunk of the rubber tree, and then the automatic fertilizer applicator 3 triggers the fertilization operation on the rubber tree.

[0069] Refer to Figure 5 、 Figure 6 and Figure 7 As shown, specifically, square grooves 35 are respectively arranged through the two first control rods 32. Control blocks 36 are slidably installed in the square grooves 35 of the first control rods 32. An induction rope 37 is connected between the two control blocks 36. The middle part of the induction rope 37 runs through the top of the first control rod 32 along the length direction of the first control rod 32 and is horizontally arranged between the two first control rods 32. A return spring 38 is installed between the control block 36 and the tail end of the first control rod 32.

[0070] It should be noted that the return spring 38 has a certain pulling force on the control block 36, so that the induction rope 37 on the control block 36 remains taut in the initial state.

[0071] In the initial state, the two first control rods 32 form a "V" - shaped structure, and the two second control rods 33 are rotationally distributed around the hinge point near the outer side wall of the first control rods 32. So that the two first control rods 32 and the two second control rods 33 are in an "M" - shaped folding state.

[0072] During specific implementation, the telescopic hydraulic cylinder 9 drives the fixed bracket 31 and the first control rods 32 and the second control rods 33 on the fixed bracket 31 to move towards the rubber tree trunk until the straightened sensing ropes 37 on the two first control rods 32 contact the rubber tree trunk. After the middle part of the sensing rope 37 contacts the rubber tree trunk, it will be squeezed by the rubber tree trunk. Therefore, the sensing rope 37 will move towards the inner side of the two first control rods 32 distributed in a "V" - shaped structure.

[0073] When the sensing rope 37 is squeezed and moves, it will stretch the control blocks 36 connected to both sides along the square groove 35 of the first control rod 32 and move towards the end far from the fixed bracket 31. When the control block 36 moves, it drives the two second control rods 33 to rotate around the hinge point towards the rubber tree trunk in the middle of the first control rod 32 until the two second control rods 33 and the two first control rods 32 all abut against the four - week of the rubber tree trunk. And at this time, the two second control rods 33 and the two first control rods 32 are distributed in a diamond shape and surround the rubber tree trunk in the middle.

[0074] After the two second control rods 33 and the two first control rods 32 are distributed in a diamond shape, the fertilizing pipes 34 clamped at their bottoms are also distributed in a diamond shape around the rubber tree trunk. Then the fertilizing pipes 34 start to spray fertilizers downward, so that the fertilizers are evenly spread around the roots of the rubber tree, which is convenient for the root system of the rubber tree to absorb the evenly spread fertilizers.

[0075] Looking back Figure 5 and Figure 6 As shown, it is a schematic structural diagram for controlling the movement of the first control rod 32 and the second control rod 33; on the control block 36 of the first control rod 32, there is a linkage component 4 for controlling the linkage expansion of the second control rod 33. The linkage component 4 includes a linkage rack plate 40 installed on the control block 36. A linkage shaft 41 is rotatably installed on the side wall of the first control rod 32 through a bracket. A linkage gear 42 is installed on the linkage shaft 41. The linkage gear 42 and the linkage rack plate 40 on the control block 36 are on the same horizontal plane; there is a control belt 43 between the linkage shaft 41 and the second control rod 33.

[0076] During specific implementation, when the control block 36 on the first control rod 32 moves along its square groove 35 towards the end away from the fixed bracket 31, the linkage rack plate 40 on the control block 36 moves synchronously. The linkage rack plate 40 will cause the linkage gear 42 meshed with the upper end of the controller to rotate. When the linkage gear 42 rotates, it drives the second control rod 33 to rotate synchronously through the control belt 43 until the two second control rods 33 rotate and abut against the rubber tree trunk.

[0077] The two second control rods 33 always rotate relative to each other, and the sensing rope 37 is inelastic. Further, the middle part of the sensing rope 37 is thicker and flatter. In this way, when the sensing rope 37 abuts against the rubber tree trunk, it can avoid the sensing rope 37 being strangled into the rubber tree trunk and causing damage to the rubber tree trunk.

[0078] The fertilization pipeline 34 of the present application, in cooperation with the first control rod 32 and the second control rod 33, can automatically wrap around the periphery of each rubber tree when fertilizing, and then evenly spread fertilizers around the rubber tree. The root system of the rubber tree is widely distributed, and uniform fertilization can ensure that the nutrients in the soil are evenly distributed, thereby improving the absorption efficiency of the roots for fertilizers. Further, uniform fertilization helps to improve the soil structure, make the soil nutrients more evenly distributed, thereby enhancing the air permeability and water retention capacity of the soil, which is beneficial to the growth of rubber trees and the latex yield.

[0079] When the first control rod 32 and the second control rod 33 surround the rubber tree trunk in a rhombus shape, the fertilization pipeline 34 also surrounds the rubber tree trunk in the same direction. At this time, the fertilization pipeline 34 can spray fertilizers downward to carry out fertilization operations on the rubber tree trunk, as follows:

[0080] Refer to Figure 8 、 Figure 9 、 Figure 10 and Figure 11 As shown in, a partition 5 is provided inside the fertilization pipeline 34 to divide the inside of the fertilization pipeline 34 into two isolated areas. One side is the fertilization area, and the other side is the control area. Five groups of fertilization ports 341 are equidistantly arranged along the length direction at the bottom of the fertilization pipeline 34.

[0081] It should be noted that the inner diameter of the fertilization pipeline 34 is relatively large, and some mechanisms can be arranged inside it. The fertilization pipeline 34 is divided into two areas. One is the control area, which is used to control the switch of fertilizer transportation in the fertilization pipeline 34; the other is the fertilization area, which is used for fertilizer transportation.

[0082] A total of five groups of fertilization ports 341 are provided, and several fertilization ports 341 are equidistantly arranged along the length direction of each group of fertilization ports 341.

[0083] There are five groups of fertilizing ports 341 arranged in the fertilizing area of the fertilizing pipeline 34, which can ensure that fertilizers are sprayed downward through the five groups of fertilizing ports 341. However, it should be noted that the five groups of fertilizing ports 341 in the fertilizing area are not opened all at once, and the opening and closing of the five groups of fertilizing ports 341 are controlled according to the thickness of the rubber tree trunk.

[0084] Refer to Figure 10 、 Figure 11 and Figure 12 As shown, it is a schematic structural diagram for controlling the opening and closing of the fertilizing port 341 in this application; two groups of symmetrically distributed arc-shaped covers 340 are slidably installed at the fertilizing port 341 in the fertilizing area of the fertilizing pipeline 34, and the arc-shaped covers 340 cover the five groups of fertilizing ports 341 of the fertilizing pipeline 34.

[0085] Arc-shaped strips 342 are respectively and staggeredly installed on the two arc-shaped covers 340, and a centered gear 343 that rotates on the inner wall of the fertilizing pipeline 34 is provided between the two arc-shaped strips 342.

[0086] In the initial state, the two arc-shaped covers 340 on the inner wall of the fertilizing pipeline 34 are attached to each other and cover the fertilizing ports 341 of the fertilizing pipeline 34, blocking all the fertilizing ports 341.

[0087] Arc-shaped strips 342 are provided on the two arc-shaped covers 340, and rotating the centered gear 343 can control the two arc-shaped covers 340 to move relatively simultaneously through the arc-shaped strips 342.

[0088] Secondly, actuating shafts 72 are installed on the opposite sides of the two centered gears 343 in the same fertilizing pipeline 34, and a universal joint 73 for driving them to rotate synchronously is jointly provided on the closer sides of the two actuating shafts 72.

[0089] The function of the universal joint 73 is to ensure that when the two fixed pipelines 344 of the fertilizing pipeline 34 rotate, the two centered gears 343 inside it can always rotate synchronously through the cooperation of the actuating shafts 72 and the universal joint 73. The universal joint 73 can ensure that the two centered gears 343 can rotate synchronously at any angle.

[0090] Refer to Figure 13 、 Figure 14 、 Figure 15 and Figure 16As shown in the figure, an opening and closing assembly 6 for controlling the opening and closing of the fertilization openings 341 on the fertilization pipeline 34 is also provided on the two arc-shaped cover plates 340. The opening and closing assembly 6 includes an opening and closing clamping plate 60 installed on the first control rod 32. Three groups of equally spaced opening and closing tooth groups 61 are provided on the opening and closing clamping plate 60. An opening and closing gear 62 is also provided on the opening and closing clamping plate 60. One side of the opening and closing gear 62 is provided with an opening and closing column 63 rotatably arranged on the control block 36. One end of the opening and closing column 63 far from the opening and closing gear 62 is installed with a first bevel gear 64. A second bevel gear 65 is meshed with the first bevel gear 64. A first shaft 66 is provided on the second bevel gear 65.

[0091] A second shaft 67 is rotatably arranged on the outer wall of the control block 36. A first belt 68 is provided between the first shaft 66 and the second shaft 67.

[0092] A telescopic column 69 is installed on the central gear 343 close to the control block 36 among the two central gears 343 in the fertilization pipeline 34. A second belt 70 is sleeved between one end of the telescopic column 69 far from the central gear 343 and the second shaft 67 on the control block 36. A passive plate 71 is also connected between the control block 36 and the telescopic column 69. One side of the passive plate 71 is slidably arranged on the fertilization pipeline 34, and a strip-shaped groove for the passive plate 71 and the second belt 70 to slide is opened on the fertilization pipeline 34.

[0093] However, it should be noted that the telescopic column 69 is a telescopic structure, and the telescopic parts of the two are serrated. The purpose is to ensure that the telescopic column 69 can follow the control block 36 to expand and contract while rotating.

[0094] It should be noted that three groups of opening and closing tooth groups 61 are equally spaced on the opening and closing clamping plate 60. Starting from the direction close to the opening and closing gear 62, they are named the first opening and closing tooth group, the second opening and closing tooth group, and the third opening and closing tooth group in turn. The first opening and closing tooth group is very close to the opening and closing gear 62.

[0095] During specific implementation, when the control block 36 moves along the square groove 35 of the first control rod 32 away from the fixed bracket 31, the opening and closing column 63 rotatably connected to the control block 36 moves synchronously. When the opening and closing gear 62 connected to the opening and closing column 63 moves synchronously, it will first come into contact with the first opening and closing tooth group on the opening and closing splint 60. Subsequently, the opening and closing gear 62 is forced to rotate. When the opening and closing gear 62 rotates, it drives the first bevel gear 64 to rotate through the opening and closing column 63. The first bevel gear 64 drives the meshing second bevel gear 65 to rotate. The second bevel gear 65 controls the second shaft 67 to rotate synchronously under the control of the first belt 68. The second shaft 67 controls the telescopic column 69 to rotate under the control of the second belt 70. The telescopic column 69 is connected to the central gear 343 on one side inside the fertilizing pipe 34. Therefore, when the telescopic column 69 rotates, it will drive the central gear 343 to rotate. When the central gear 343 rotates, it will control the two arc-shaped covers 340 to move away from each other. At this time, a group of fertilizing ports 341 located in the middle of the fertilizing pipe 34 is opened.

[0096] When the control block 36 continues to move, when the opening and closing gear 62 meshes with the second opening and closing tooth group on the opening and closing splint 60, the above operations are repeated, and two groups of fertilizing ports 341 near the middle fertilizing port 341 in the fertilizing pipe 34 are opened. At this time, a total of three groups of fertilizing ports 341 have been opened.

[0097] When the control block 36 still moves, when the opening and closing gear 62 meshes with the third opening and closing tooth group on the opening and closing splint 60, the above operations are repeated, and the remaining two groups of fertilizing ports 341 in the fertilizing pipe 34 are opened. At this time, all five groups of fertilizing ports 341 are opened.

[0098] If the rubber tree trunk contacted by the induction rope 37 is relatively thin, the control block 36 can only move to the position between the first opening and closing tooth group and the second opening and closing tooth group. At this time, only a group of fertilizing ports 341 located in the middle position in the fertilizing pipe 34 is opened. Then, the fertilizing ports 341 spray fertilizer downward to fertilize the rubber tree trunk. Because the rubber tree trunk is relatively thin, the amount of fertilizer it can absorb is less. Therefore, opening a group of fertilizing ports 341 is sufficient, and the fertilizer sprayed downward by a group of fertilizing ports 341 per unit time can be absorbed by it.

[0099] If the size of the rubber tree trunk contacted by the induction rope 37 is relatively small, the control block 36 can move to the position between the second opening and closing tooth group and the third opening and closing tooth group. At this time, three groups of fertilizing ports 341 near the middle position in the fertilizing pipe 34 are opened. Then, the three groups of fertilizing ports 341 spray fertilizer downward to fertilize the rubber tree trunk. Because the rubber tree trunk is relatively thick, the amount of fertilizer it can absorb is more. Therefore, opening three groups of fertilizing ports 341 is sufficient, and the amount of fertilizer sprayed downward by three groups of fertilizing ports 341 per unit time can be absorbed by it.

[0100] When the size of the rubber tree trunk contacted by the induction rope 37 is very thick, the control block 36 can cross the third opening and closing tooth group. At this time, all five fertilizer application ports 341 in the fertilizer application pipeline 34 are opened. Then, the five fertilizer application ports 341 spray fertilizer downward to perform fertilizer application operations on the rubber tree trunk. Because the rubber tree trunk is very thick and can absorb a large amount of fertilizer, all five fertilizer application ports 341 need to be opened, and the amount of fertilizer sprayed downward by the five fertilizer application ports 341 per unit time can be absorbed by it.

[0101] Embodiment 2:

[0102] On the basis of Embodiment 1, in order to further improve the efficiency of automatically adjusting the fertilizer application amount for rubber tree trunks of different thicknesses in this application, the present application proposes an adjusting member 8. Refer to Figure 17 As shown, the adjusting member 8 includes an adjusting groove 80 provided on the opening and closing clamping plate 60. The opening and closing tooth group 61 is slidably disposed in the adjusting groove 80 of the opening and closing clamping plate 60, and a plurality of adjusting screws 81 corresponding to the opening and closing tooth group 61 are screwed through the side wall of the opening and closing clamping plate 60.

[0103] During specific implementation, it is described above that the amount of fertilizer applied is automatically adjusted according to the thickness of different rubber tree trunks. However, it should be noted that how to judge the thickness of the rubber tree trunk, because the judgment criteria for its thickness are different in each rubber tree planting area. Therefore, in order to ensure the applicability of the entire device, the present application proposes an adjusting member 8. First, scale labels are engraved on the opening and closing clamping plate 60, which are not shown in the figure. When the staff in a certain planting area needs to apply fertilizer to rubber trees, first adjust the positions of the three opening and closing tooth groups on the opening and closing plate in sequence.

[0104] When the first opening and closing tooth group moves away from the opening and closing gear 62 on the opening and closing column 63, the distance between the opening and closing gear 62 and the first opening and closing tooth group becomes longer. At this time, the induction rope 37 needs to be pulled longer, and the control block 36 moves a farther distance. At this time, the diameter of the corresponding tree will also become thicker. Therefore, by controlling the distance between the opening and closing tooth group 61 and the opening and closing gear 62 in the initial state, the opening timing of the fertilizer application port 341 on the fertilizer application pipeline 34 can be controlled.

[0105] Furthermore, due to the different situations of rubber tree planting in different regions, because some regions are tropical rainforest regions and are very suitable for the growth of rubber trees, so rubber trees basically grow tall and thick. At this time, the judgment criteria for the thickness of rubber trees in this region need to be improved.

[0106] Then, in some regions, because the weather has been dry for a longer time, some rubber trees grow well and some grow poorly. At this time, the rubber trees in this region grow thick and thin, and the judgment criteria for the thickness of rubber trees in this region need to be improved manually for applicability.

[0107] Refer to Figure 18 As shown in Figure 18 , an automatic fertilization process for natural rubber planting uses the automatic fertilization device for natural rubber planting in claim 1, and is characterized in that: the automatic fertilization process for natural rubber planting is as follows:

[0108] S1. Material filling: First, check the entire device and maintain it. Then, load the fertilizers required for fertilization into the two storage bins 2 on the mobile vehicle, and ensure the tightness of the fertilizers to prevent the fertilizers from getting damp and deteriorating, which will affect their quality.

[0109] S2. Height adjustment: During the fertilization process, according to the flatness of the terrain, automatically adjust the vertical frame 30 of the automatic fertilizer applicator 3 to adjust the height of the fixed bracket 31 through the electric telescopic system at its upper end, so that the height of each fertilization is always consistent with the bottom of the rubber tree, thereby ensuring that the fertilizers are spread more evenly.

[0110] S3. Automatic fertilization: First, drive the control vehicle 1 to the designated area in the rubber planting area. Then, start the telescopic hydraulic cylinder 9. The output end of the telescopic hydraulic cylinder 9 controls the fixed bracket 31 to extend towards the trunk of the rubber tree. The telescopic hydraulic cylinder 9 drives the fixed bracket 31 and the first control rod 32 and the second control rod 33 on the fixed bracket 31 to move towards the trunk of the rubber tree until the sensing ropes 37 stretched on the two first control rods 32 contact the trunk of the rubber tree. After the middle of the sensing rope 37 contacts the trunk of the rubber tree, it will be squeezed by the trunk of the rubber tree.

[0111] When the sensing rope 37 is squeezed and moves, it will stretch the control blocks 36 connected to both sides along the square groove 35 of the first control rod 32 and move towards one end away from the fixed bracket 31. When the control blocks 36 move, they drive the two second control rods 33 to approach the trunk of the rubber tree in the middle of the first control rod 32 through the linkage component 4 until the two second control rods 33 and the two first control rods 32 all abut against the periphery of the trunk of the rubber tree. At this time, the two second control rods 33 and the two first control rods 32 are distributed in a diamond shape and enclose the trunk of the rubber tree in the middle. Then, control the automatic fertilizer applicator 3 to fertilize each rubber tree.

[0112] If the trunk of the rubber tree contacted by the sensing rope 37 is relatively thin, the control block 36 can only move to the position between the first opening and closing tooth group and the second opening and closing tooth group. At this time, only a group of fertilization ports 341 located in the middle position in the fertilization pipeline 34 are opened. Then, the fertilization ports 341 spray fertilizers downward to perform fertilization operations on the trunk of the rubber tree. Because the trunk of the rubber tree is relatively thin and the amount of fertilizers it can absorb is less, only one group of fertilization ports 341 needs to be opened. The fertilizers sprayed downward by one group of fertilization ports 341 per unit time can be absorbed by it.

[0113] When the size of the rubber tree trunk contacted by the induction rope 37 is relatively small, the control block 36 can move to the position between the second opening and closing tooth group and the third opening and closing tooth group. At this time, three fertilizer outlets 341 near the middle position in the fertilizer pipeline 34 are opened. Then, the three fertilizer outlets 341 spray fertilizer downward to fertilize the rubber tree trunk. Since the rubber tree trunk is relatively thick and can absorb more fertilizer, it is sufficient to open the three fertilizer outlets 341. The amount of fertilizer sprayed downward by the three fertilizer outlets 341 per unit time can be absorbed by it.

[0114] When the size of the rubber tree trunk contacted by the induction rope 37 is extremely thick, the control block 36 can cross the third opening and closing tooth group. At this time, all five fertilizer outlets 341 in the fertilizer pipeline 34 are opened. Then, the five fertilizer outlets 341 spray fertilizer downward to fertilize the rubber tree trunk. Since the rubber tree trunk is extremely thick and can absorb a large amount of fertilizer, it is necessary to open all five fertilizer outlets 341. The amount of fertilizer sprayed downward by the five fertilizer outlets 341 per unit time can be absorbed by it.

[0115] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
