Description

Technical Field

[0001] The invention relates to the technical field of rubber tree planting, in particular to a deep tillage and fertilization device and a deep fertilization method for rubber trees. Background Art

[0002] Rubber trees are an important economic crop that needs to grow in a specific environment to achieve the best yield and quality. Rubber trees need fertile, well-drained acidic soil. Acidic soil helps maintain nutrients in the soil and prevents nutrient loss. Rubber trees need sufficient water to grow normally. In the dry season, rubber trees need to be provided with sufficient water to maintain their growth rate and the density of the crown.

[0003] When planting rubber trees, first the rubber tree seeds are germinated into seedlings. After the seedlings grow to a certain size, holes are dug for planting the rubber tree seedlings. When planting, first dig holes in the selected planting site, then place the roots of the seedlings in the deep holes, and cover with soil, apply fertilizer, etc. In actual planting, rubber tree seedlings like fertilizer but avoid concentrated fertilizer. If fertilizer is applied directly to the roots of the seedlings, it will affect the growth of the seedlings. In addition, rubber tree seedlings like a slightly moist and dry soil environment. If soil is covered directly, although the soil can be kept slightly moist at the time, the soil becomes compacted during the subsequent growth process. Even if watering or raining is carried out externally, it is difficult to change the dry and wet environment inside the soil, which affects the growth of the rubber tree seedlings. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the present invention provides a deep tillage fertilization device and a deep fertilization method for rubber trees. The device has the functions of crushing a mixed soil and leaf mixture and discharging it into a tree pit, burying the roots of the seedlings, drilling the soil through a spiral soil-breaking component to form a fertilization deep pit, collecting the soil and leaves, and mixing the soil and leaves with the driving of the spiral soil-breaking component to form a loose soil and leaf mixture. After the fertilization is completed, the deep pit is filled with part of the mixed soil, so that rainwater can better enter the deep pit to penetrate fertilizer nutrients into the deep layer, etc., and solves the problem that in actual planting, the rubber seedlings like fertilizer but avoid concentrated fertilizer. If fertilizer is directly applied to the roots of the seedlings, the growth of the seedlings will be affected. Moreover, the rubber seedlings like a slightly moist and dry soil environment. If soil is directly covered, although the soil can be guaranteed to be slightly moist at that time, the soil becomes compact in the subsequent growth process.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present invention provides a deep tillage and fertilization device and a deep fertilization method for rubber trees, which have the following beneficial effects:

[0019] 1. The deep tillage and fertilization device drives the soil delivery mechanism to operate through the transmission component. When the soil delivery mechanism operates, the soil and surrounding leaves are delivered to the collecting and mixing component. At the same time, under the action of the transmission component, the crushing and mixing mechanism operates to crush and mix the delivered soil and leaves in the mixing bin; then after a tree pit is formed, the deep tillage frame is moved, and the central rod sleeve in the collecting and mixing component is placed directly in the newly drilled tree pit. A sapling is placed in the middle of the central rod sleeve through the tree planting mechanism. After the sapling is placed in the tree pit (in this process, by mixing the soil and leaves The tree planting mechanism drives the center rod sleeve to rise, so that a gap is formed between the center rod sleeve and the bottom of the mixing bin, and then the mixed soil and leaf mixture is broken up and discharged into the tree pit to bury the roots of the seedlings. The soil is drilled through the spiral soil-breaking component to form a deep fertilization pit, and the soil and leaves are collected. The soil and leaves are mixed with the drive of the spiral soil-breaking component to form a loose soil and leaf mixture. After the fertilization is completed, part of the mixed soil is used to fill the deep pit so that rainwater can better enter the deep pit and penetrate the fertilizer nutrients into the deep layer.

[0020] 2. The deep tillage and fertilization device collects leaves and soil discharged from the discharge trough at the bottom of the drilling tube through the soil storage cavity in the soil delivery mechanism. At the same time, driven by the transmission component, the guide telescopic rod drives the diffusion gear to rotate, and the diffusion gear drives the rotating ring to rotate through the diffusion teeth meshing with it. Then the rotating ring drives the diffusion rods on its circumferential side to rotate inside the soil storage cavity. The diffusion rods move the leaves and soil inside the soil storage cavity, so that the leaves and soil are transported to the collection and mixing component.

[0021] 3. The deep tillage and fertilization device is slidably arranged on both sides above the deep tillage frame through the separation frame in the tree planting mechanism. The separation frame is moved to both sides or the middle under the drive of the separation cylinder. When moving to the middle, the mixing bin and the center rod sleeve can be merged to form a whole. When moving to both sides, the mixing bin and the center rod sleeve are separated under the drive of the separation frame to form a channel therebetween, so that the planted seedlings can pass through the channel, and then the seedlings can be moved out of the tree planting mechanism.

[0022] 4. The deep tillage and fertilization device is located inside the separation frames through the crushing and mixing mechanisms. When the separation frames are merged, the crushing and mixing mechanisms surround the two sides of the central rod sleeve, and then the crushing rod drives the crushing teeth to rotate inside the mixing bins on both sides of the central rod sleeve under the drive of the transmission assembly, and then the crushing teeth crush and mix the leaves and soil in the mixing bin, and then the saplings are sent to the middle of the central rod sleeve through the sapling clamp, and the roots of the saplings are made to enter the drilled deep pit, and then the crushed and mixed leaves and soil mixture is discharged into the central rod sleeve through the soil covering groove at the bottom of the central rod sleeve, and the roots of the saplings in the deep pit at the bottom of the central rod sleeve are buried.

[0023] 5. The deep tillage and fertilization device cooperates with the upper telescopic sleeve rod, the telescopic inner rod and the lower telescopic sleeve rod in the guiding telescopic rod. When the propulsion cylinder drives the deep tillage motor to move downward, the propulsion cylinder drives the linkage gear (the linkage gear and the output end of the deep tillage motor are provided with a connecting frame, and the linkage gear and the output end of the deep tillage motor are respectively coordinated with the connecting frame for fixed-point rotation) to move downward, and the linkage gear drives the telescopic inner rod to move downward between the upper telescopic sleeve rod and the lower telescopic sleeve rod. When moving downward, the guide block at the bottom of the telescopic inner rod first contacts the arc structure at the top of the lower telescopic sleeve rod, and moves downward along the arc structure to the guide groove of the lower telescopic sleeve rod, and then the telescopic inner rod drives the lower telescopic sleeve rod to rotate through the guide block at its bottom in cooperation with the guide groove in the lower telescopic sleeve rod, thereby driving the diffusion gear to rotate. At the same time, the guide block at the top of the telescopic inner rod is in the guide groove in the upper telescopic sleeve rod, driving the upper telescopic sleeve rod to rotate synchronously.

[0046] Then, when the soil delivery mechanism 22 is in operation, the soil and the surrounding leaves are delivered to the collecting and mixing component 3. At the same time, under the action of the transmission component 5, the crushing and mixing mechanism 32 is in operation to crush and mix the delivered soil and leaves in the mixing bin 33; the leaves and soil discharged from the discharge trough 224 at the bottom of the soil drilling tube 23 are collected through the soil storage cavity 221 in the soil delivery mechanism 22. At the same time, under the drive of the transmission component 5, the guide telescopic rod 227 drives the diffusion gear 226 to rotate, and the diffusion gear 226 drives the rotating ring 226 through the diffusion teeth 225 meshing therewith. 23 rotates, and then the rotating ring 223 drives the diffusion rod 222 on its peripheral side to rotate inside the soil storage cavity 221, and the diffusion rod 222 moves the leaves and soil inside the soil storage cavity 221, so that the leaves and soil are transported to the collecting and mixing component 3; wherein the soil delivery trough 26 opened on one side of the soil storage cavity 221, through the rotation direction of the diffusion rod 222, which is opposite to the rotation direction of the diffusion rod 222 and has an arc structure, the leaves and soil in the soil storage cavity 221 are gathered in the soil delivery trough 26, and then the leaves and soil are sent to the mixing bin 33 in the collecting and mixing component 3 through the soil delivery trough 26;

[0047] Then, after a tree pit is formed, the deep tillage frame 1 is moved, and the central rod sleeve 31 in the collecting and mixing component 3 is placed directly in the newly drilled tree pit, and a sapling is placed in the middle of the central rod sleeve 31 through the tree planting mechanism 4. After the sapling is placed in the tree pit, the tree planting mechanism 4 drives the central rod sleeve 31 to rise, so that a gap is formed between the central rod sleeve 31 and the bottom of the mixing bin 33, and then the mixed soil and leaf mixture is broken up and discharged into the tree pit, and the separation frame 41 in the tree planting mechanism 4 is slidably arranged on both sides above the deep tillage frame 1, and the separation frame 41 is moved to both sides or the middle under the drive of the separation cylinder 411. When moving to the middle, the mixing bin 33 and the central rod sleeve 31 can be merged to form a whole. When moving to both sides, the mixing bin 33 and the central rod sleeve 31 are separated under the drive of the separation frame 41, so that a channel is formed between them, so that the planted sapling can pass through the channel, and then the sapling can be moved out of the tree planting mechanism 4;

[0048] In the above process, the crushing and mixing mechanisms 32 are respectively located inside the separation frames 41. When the separation frames 41 are merged, the crushing and mixing mechanisms 32 surround the two sides of the central rod sleeve 31, and then, driven by the transmission assembly 5, the crushing rods 322 respectively drive the crushing teeth 321 to rotate inside the mixing bins 33 on both sides of the central rod sleeve 31, so that the crushing teeth 321 crush and mix the leaves and soil in the mixing bins 33, and then the crushed and mixed leaves and soil mixture is discharged into the central rod sleeve 31 through the soil covering groove 311 at the bottom of the central rod sleeve 31, and the roots of the seedlings in the deep pit at the bottom of the central rod sleeve 31 are buried;

[0049] The guide rod 412 provided in the middle of the separation frame 41 enables the center rod sleeve 31 to slide up and down along the guide rod 412. When the sapling clamp 42 places the sapling in the deep pit at the bottom of the center rod sleeve 31, the elastic clamp 421 at the bottom of the sapling clamp 42 contacts the center rod sleeve 31 and clamps the center rod sleeve 31. When the sapling clamp 42 moves upward, the center rod sleeve 31 is driven upward, so that the soil covering groove 311 at the bottom of the center rod sleeve 31 leaks out, and then the mixture of leaves and soil is discharged from the soil covering groove 311 into the deep pit. When the center rod sleeve 31 rises to contact the stopper 413, the stopper 413 restricts the center rod sleeve 31 from continuing to move upward, thereby separating the center rod sleeve 31 from the elastic clamp 421.

[0050] The linkage gear 51 in the transmission assembly 5 is meshed with the output end of the deep plowing motor 25. When the deep plowing motor 25 rotates, the linkage gear 51 is driven to rotate, and the linkage gear 51 drives the guide telescopic rod 227 to rotate. The guide telescopic rod 227 drives the passive pulley 54 at the other end to rotate through the linkage pulley 52 and the transmission belt 53, thereby rotating the breaking rod 322; the upper telescopic sleeve rod 228, the telescopic inner rod 229 and the lower telescopic sleeve rod 230 in the guide telescopic rod 227 cooperate, and when the propulsion cylinder 24 drives the deep plowing motor 25 to move downward, the propulsion cylinder 24 drives the linkage gear 51 (the linkage gear 51 and the output end of the deep plowing motor 25 are provided with a connecting frame, and the linkage gear 51 and the output end of the deep plowing motor 25 are respectively connected to the connecting frame The telescopic inner rod 229 is moved downwardly between the upper telescopic sleeve rod 228 and the lower telescopic sleeve rod 230 by the linkage gear 51. When moving downwardly, the guide block 232 at the bottom of the telescopic inner rod 229 first contacts the arc structure at the top of the lower telescopic sleeve rod 230, and moves downwardly along the arc structure to the guide groove 231 of the lower telescopic sleeve rod 230. Then, the telescopic inner rod 229 drives the lower telescopic sleeve rod 230 to rotate through the guide block 232 at its bottom in cooperation with the guide groove 231 in the lower telescopic sleeve rod 230, thereby driving the diffusion gear 226 to rotate. At the same time, the guide block 232 at the top of the telescopic inner rod 229 is in the guide groove 231 in the upper telescopic sleeve rod 228, driving the upper telescopic sleeve rod 228 to rotate synchronously.

[0051] Then, the sapling is sent to the middle of the central pole sleeve 31 through the sapling clamp 42, and the roots of the sapling are made to enter the drilled deep pit to bury the roots of the sapling. The soil is drilled through the spiral soil-breaking component 2 to form a fertilization deep pit, and the soil and leaves are collected. The soil and leaves are mixed by the driving of the spiral soil-breaking component 2 to form a loose soil and leaf mixture. After the fertilization is completed, part of the mixed soil is used to fill the deep pit so that rainwater can better enter the deep pit and penetrate fertilizer nutrients into the deep layer.
