Description

Technical Field

[0001] The invention relates to the technical field of seedling fertilization, in particular to a fertilization device for forestry seedling cultivation. Background Art

[0002] Forestry seedling cultivation is the process of cultivating forest seedlings under human control using vegetative propagation materials or tissue culture materials. Seedlings are cultivated by inserting branches. It is suitable for some tree species that are easy to root, such as poplar and willow. Cutting seedling cultivation should pay attention to the selection and treatment of cuttings, as well as the management after cutting.

[0003] In order to concentrate the fertilizer in the main area where the roots of the seedlings are distributed, make the fertilizer closer to the absorbing roots of the seedlings, thereby improving the utilization rate of the fertilizer, ensuring that the seedlings can fully absorb nutrients, and avoid the loss of nutrients due to rain erosion or watering after the fertilizer is spread on the surface, and reduce waste, it is usually necessary to dig holes around the seedlings for fertilization.

[0004] A large diameter of the sapling means that its root system is more developed and the absorbing roots are distributed over a wider range. If the pit is dug close to the sapling and the fertilizer concentration is too high after fertilization, it is easy to burn the root system, especially the tender absorbing roots, affecting the sapling's absorption of water and nutrients, and thus leading to poor growth of the sapling or even death.

[0005] Existing pit fertilization is usually carried out manually. Manual pit fertilization requires digging holes and placing fertilizer one by one. The process is cumbersome and takes a lot of time and manpower. Especially in large-scale planting, it is inefficient and may cause uneven distribution of nutrients in the soil. Long-term pit fertilization at a fixed location will make the local soil nutrient concentration too high, while other areas are relatively lacking in nutrients, affecting the balanced absorption of nutrients by the roots.

[0006] Therefore, it is necessary to design a forestry seedling fertilization device that can adjust the digging fertilization distance and the fertilization amount. Summary of the Invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The diameter of the sapling is calculated by the distance extended by the output end of the hydraulic cylinder, and then each fertilizing mechanism is controlled to expand or retract according to the diameter of the sapling, that is, to move away from or close to the sapling.

[0020] 2. The fertilizer is blocked by the baffle, so that the fertilizer enters the interior of the transmission box in sequence. When the gravity of the fertilizer gradually exceeds the spring force of the spring, the spring is compressed, thereby driving the inclined plate to move downward, and then driving the baffle to move downward until the spring is compressed to the limit. At this time, the top of the baffle is flush with the sliding surface of the spiral disk, and the fertilizer slides down again until it encounters the next baffle. The fertilizer is blocked again and enters the interior of the transmission box, thereby evenly transmitting the total fertilizer to the interior of each transmission box, so that the amount of fertilizer inside each transmission box is the same, and then the fertilizer distributed to the interior of each storage box is the same, effectively preventing the storage box with too little fertilizer from not having enough fertilizer during fertilization, resulting in uneven fertilizer around the tree roots.

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] For example 1, please refer to Figures 1-11 The present invention provides a technical solution: a fertilizing device for forestry seedling cultivation, comprising an electric trolley 1 and a control box, an electric lifting platform 2 for controlling the depth of fertilization fixedly connected to the upper side of the electric trolley 1, a rotating mechanism 3 for controlling the direction of fertilization provided at the lifting end of the electric lifting platform 2, a conveying mechanism 4 for evenly distributing fertilizer to different positions provided on the upper side of the rotating mechanism 3, an unfolding mechanism 5 for adjusting the distance between the fertilizer and the roots of the tree provided on one side of the conveying mechanism 4, and a plurality of fertilizing mechanisms 6 for placing the fertilizer into the soil provided on the outer side of the unfolding mechanism 5.

[0040] See also Figure 2 The rotating mechanism 3 includes a support platform 31 fixedly connected to the lifting end of the electric lifting platform 2, and a first motor 32 is fixedly connected to the lower side of the support platform 31. The output end of the first motor 32 passes through the support platform 31 and is fixedly connected to the first rotating drum 33. A second rotating drum 34 is provided on one side of the first rotating drum 33, and the second rotating drum 34 is connected to the support platform 31 with a bearing, and the second rotating drum 34 is connected to the first motor 32 with a belt.

[0041] Specifically, the rotation of the output end of the first motor 32 is used to control the rotation of the fertilizing mechanism 6, so that the fertilizing mechanism 6 fertilizes the saplings on both sides of the electric cart 1. When the saplings on the left side of the electric cart 1 need to be fertilized, the output end of the first motor 32 rotates ninety degrees counterclockwise. When the saplings on the right side of the electric cart 1 need to be fertilized, the output end of the first motor 32 rotates ninety degrees clockwise.

[0042] See also Figure 7 and Figure 8 The unfolding mechanism 5 includes a fixed plate 58 fixedly connected to the other end of the connecting block 42, and a plurality of fixed bars 582 are evenly fixedly connected to the upper side of the fixed plate 58. A slide 583 is slidably connected between every two fixed bars 582. The upper side of each slide 583 is fixedly connected to a slide column 52, and the upper side of every two fixed bars 582 is fixedly connected to a guide slide 581. The upper side of the guide slide 581 is slidably connected to the first gear 51. A measuring groove 512 is provided in the middle of the first gear 51 and five arc grooves 511 are evenly provided inside. The arc groove 511 is slidably connected to the slide column 52.

[0043] Specifically, the rotation of the output end of the third motor 56 is used to control the rotation of the second gear 55, thereby driving the first gear 51 to rotate, and then driving the sliding column 52 to slide inside the arc groove 511, driving the slide plate 583 to slide along the fixed bar 582, and the inside of the measuring groove 512 is used to pass the sapling, so as to measure the diameter of the sapling, and estimate the root range of the sapling based on the diameter of the sapling.

[0044] An L-shaped plate 57 is fixedly connected to the lower side of the fixed plate 58, and a third motor 56 is fixedly connected to the upper side of the L-shaped plate 57. The output end of the third motor 56 is fixedly connected to the second gear 55, and the second gear 55 is meshed with the first gear 51. The lower side of the fixed plate 58 is also fixedly connected to the hydraulic cylinder 53, and the output end of the hydraulic cylinder 53 is fixedly connected to the pressure sensor 54.

[0045] Specifically, the extension and retraction of the output end of the hydraulic cylinder 53 is used to drive the pressure sensor 54 to move closer or farther away. When the pressure sensor 54 detects a pressure value, the output end of the hydraulic cylinder 53 stops extending and retracting.

[0046] When the stroke of the hydraulic cylinder 53 hand output end is within half of the stroke, the control box determines that the sapling is in the mature stage. The root distribution range of the mature sapling is too large, and it is necessary to dig and fertilize away from the roots. The control box controls the output end of the third motor 56 to rotate clockwise, thereby driving the first gear 51 to rotate counterclockwise, and the sliding column 52 slides inside the arc groove 511 and gradually moves away from the measuring groove 512, thereby driving the slide plate 583 to slide along the fixed bar 582, driving the fertilizing mechanism 6 away from the sapling.

[0047] When the stroke extended by the output end of the hydraulic cylinder 53 is greater than or equal to one-half of the stroke, the control box determines that the sapling is in the hard-branch stage. The root distribution range of the sapling in the hard-branch stage is too small, and it is necessary to dig soil and fertilize close to the roots. The control box controls the output end of the third motor 56 to rotate counterclockwise, thereby driving the first gear 51 to rotate clockwise, and the sliding column 52 slides inside the arc groove 511 and gradually approaches the measuring groove 512, thereby driving the slide plate 583 to slide along the fixed bar 582, driving the fertilizing mechanism 6 to approach the sapling.

[0048] See also Figures 9-11 The fertilizing mechanism 6 includes a material storage box 61 fixedly connected to one side of the slide plate 583, a seasoning box 62 and a fourth motor 63 are fixedly connected to the lower side of the material storage box 61, an auger head 65 is rotatably connected to the lower side of the seasoning box 62, a fourth rotating drum 66 is fixedly connected to the outer side of the auger head 65, an output end of the fourth motor 63 is fixedly connected to the third rotating drum 64, the third rotating drum 64 is connected to the fourth rotating drum 66 by a belt, a baffle 67 is provided on the lower side of the fourth rotating drum 66, and the baffle 67 is fixedly connected to the auger head 65.

[0049] Specifically, the storage box 61 is used to store the divided fertilizer, and the seasoning box 62 is used to regulate the amount of fertilizer applied so that the amount of fertilizer applied at each position around the tree roots is more uniform. The rotation of the output end of the fourth motor 63 is used to control the rotation of the third rotating drum 64, thereby driving the fourth rotating drum 66 to rotate, and then driving the spiral drill bit 65 to rotate to drill holes in the soil below and apply fertilizer.

[0050] Two guide plates 621 are fixedly connected to the inside of the seasoning box 62, and a fifth motor 624 is fixedly connected to one side of the seasoning box 62. The output end of the fifth motor 624 passes through the seasoning box 62 and is fixedly connected to the central shaft 622. Several rotating plates 623 are evenly fixedly connected to the outside of the central shaft 622.

[0051] Specifically, the rotation of the output end of the fifth motor 624 is used to control the rotation of the central shaft 622, thereby controlling the rotating plate 623 to rotate with the central shaft 622 as the axis. The fertilizer will enter between the two rotating plates 623 in turn, and the quantitative fertilizer will be transported to the inside of the spiral drill head 65 through rotation.

[0052] A hanging ring 651 is fixedly connected to the upper side of the spiral drill bit 65, and the hanging ring 651 is arranged inside the seasoning box 62. A feeding channel is provided inside the spiral drill bit 65, and a first discharge trough is provided on the lower side of the feeding channel. A sixth motor 653 is fixedly connected to the lower part of the feeding channel, and a hollow column 652 is fixedly connected to the output end of the sixth motor 653. A second discharge trough is provided on one side of the hollow column 652. The interior of the hollow column 652 is hollow and a slope 654 is provided on the lower side.

[0053] Specifically, in the initial state, the first discharge chute and the second discharge chute are not connected. When the trolley moves between the two saplings, the electric lifting platform 2 controls the first gear 51 to move upward until it is higher than the height of the saplings. The rotating mechanism 3 controls the first gear 51 to rotate. At this time, the first gear 51 is located directly above the saplings. The electric lifting platform 2 controls the first gear 51 to move downward, so that the saplings enter the interior of the measuring groove 512. The extension of the output end of the hydraulic cylinder 53 drives the pressure sensor 54 close to the sapling until the pressure sensor 54 detects a pressure value. The output end of the hydraulic cylinder 53 stops extending. According to the extension distance of the hydraulic cylinder 53, the pressure sensor 54 moves closer to the sapling. The diameter of the sapling is calculated. The longer the distance that the output end of the hydraulic cylinder 53 extends, the smaller the diameter of the sapling. The control box calculates the diameter of the sapling based on the distance that the output end of the hydraulic cylinder 53 extends, and then controls each fertilizing mechanism 6 to expand or retract according to the diameter of the sapling, that is, away from or close to the sapling. When the fertilizing mechanism 6 is controlled to move to the appropriate position, the rotation of the output end of the fifth motor 624 controls the central shaft 622 to rotate, thereby controlling the rotating plate 623 to rotate with the central shaft 622 as the axis. The fertilizer will enter between the two rotating plates 623 in turn, and the quantitative fertilizer will be transported to the inside of the spiral drill head 65 through rotation.

[0054] At the same time, the electric lifting platform 2 controls the fertilizing mechanism 6 to continue to descend, and the rotation of the output end of the fourth motor 63 controls the third rotating drum 64 to rotate, thereby driving the fourth rotating drum 66 to rotate, and then driving the spiral drill bit 65 to rotate to drill holes in the soil below. When the drilling is completed, the electric lifting platform 2 controls the fertilizing mechanism 6 to move upward, and at the same time, the output end of the sixth motor 653 rotates ninety degrees to connect the first discharge trough and the second discharge trough. At this time, the fertilizer inside the spiral drill bit 65 falls downward along the inclined surface 654, thereby sliding the fertilizer into the hole below, thereby completing the digging of holes around the saplings and fertilizing.

[0055] The diameter of the sapling is calculated by the distance extended by the output end of the hydraulic cylinder 53, and then each fertilizing mechanism 6 is controlled to expand or retract according to the diameter of the sapling, that is, away from or close to the sapling. At the same time that the spiral drill bit 65 finishes drilling and lifts upward, the sixth motor 653 controls the first discharge trough and the second discharge trough to be connected, so that the fertilizer inside the spiral drill bit 65 falls evenly into the hole along the inclined surface 654, effectively preventing long-term digging and fertilizing at a fixed position, which makes the local soil nutrient concentration too high, resulting in relative lack of nutrients in other areas, affecting the balanced absorption of nutrients by the roots, and achieves the effect of adaptively adjusting the fertilization distance according to the diameter of the sapling.

[0056] In the second embodiment, in order to prevent the waste of transportation time and the increase of fertilizer delivery time, the total fertilizer is usually divided into the storage boxes 61 at different positions before fertilizing. Since the distribution is uneven each time, the amount of fertilizer in each storage box 61 is different, which leads to too little fertilizer in some storage boxes 61. As a result, the storage boxes 61 with too little fertilizer have insufficient fertilizer during fertilization, resulting in uneven fertilizer around the tree roots, affecting the growth rate and nutrition of the seedlings. Therefore, the following structure is designed to solve the above technical problems.

[0057] See also Figure 3-Figure 6 The conveying mechanism 4 includes a support plate 41 fixedly connected to the upper side of the second rotating drum 34, a storage box 43 is fixedly connected to the upper side of the support plate 41, a discharge channel 44 is connected to one side of the storage box 43, and two connecting blocks 42 are fixedly connected to one side of the support plate 41.

[0058] Specifically, the storage box 43 is used to store the total fertilizer, and the discharge channel 44 is used to transport the total fertilizer, thereby performing material distribution.

[0059] A right-angle plate 45 is fixedly connected to the upper side of the connecting block 42 , a spiral disk 47 is fixedly connected to one side of the right-angle plate 45 , five limit assemblies 46 are evenly arranged inside the spiral disk 47 , and a residual material collection box 48 is fixedly connected to the end of the spiral disk 47 .

[0060] Specifically, the total fertilizer inside the storage box 43 flows to the top of the spiral disk 47 through the discharge channel 44. Due to gravity, the fertilizer will slide inside the spiral disk 47. The baffle 465 limits the fertilizer and controls the baffle 465 to move up and down through the gravity of the fertilizer, so that the fertilizer is transported to the transmission box 461 of each limiting component 46 in turn. The residual material collection box 48 is used to collect excess fertilizer.

[0061] The limiting assembly 46 includes a transmission box 461 fixedly connected to the inside of the spiral disk 47, and the transmission box 461 is slidably connected to the inside of the transmission box 461. A slider 464 is fixedly connected to one side of the inclined plate 463, and a baffle 465 is fixedly connected to the other side of the slider 464, and the baffle 465 is slidably connected to the spiral disk 47. Two springs 468 are fixedly connected to the lower side of the inclined plate 463, and the other end of each spring 468 is fixedly connected to the transmission box 461. A second motor 462 is fixedly connected to one side of the transmission box 461, and the output end of the second motor 462 passes through the transmission box 461 and is fixedly connected to the rotating shaft 467. The outer side of the rotating shaft 467 is fixedly connected to the discharge gate 466.

[0062] Specifically, in the initial state, the baffle 465 is higher than the sliding surface of the spiral disk 47, so the baffle 465 will block the sliding fertilizer. When the sliding fertilizer is blocked by the baffle 465, the fertilizer will enter the interior of the transmission box 461, that is, above the inclined plate 463. Since the gravity of the fertilizer gradually exceeds the spring force of the spring 468, the spring 468 is compressed, thereby driving the inclined plate 463 to move downward, and then driving the baffle 465 to move downward until the spring 468 is compressed to the limit. At this time, the top of the baffle 465 is flush with the sliding surface of the spiral disk 47, and the fertilizer slides down again until it encounters the next baffle 465. The fertilizer is blocked again and enters the interior of the transmission box 461. By analogy, the five limit assemblies 46 are evenly distributed. When the baffle 465 of the last limit assembly 46 moves downward and the top of the baffle 465 is flush with the sliding surface of the spiral disk 47, the storage box 43 stops feeding, and all the output ends of the second motor 462 rotate ninety degrees clockwise, driving the discharge door 466 to open. At this time, all the fertilizers slide downward along the inclined plate 463 and fall into the interior of the storage box 61. During the falling of the fertilizer, the spring 468 gradually drives the inclined plate 463 to move upward, causing it to return to its position, until the fertilizer above the inclined plate 463 falls into the interior of the storage box 61, and the output end of the second motor 462 rotates ninety degrees counterclockwise, driving the discharge door 466 to close.

[0063] The fertilizer is blocked by the baffle 465, so that the fertilizer enters the interior of the transmission box 461 in turn. When the gravity of the fertilizer gradually exceeds the spring force of the spring 468, the spring 468 is compressed, thereby driving the inclined plate 463 to move downward, and then driving the baffle 465 to move downward until the spring 468 is compressed to the limit. At this time, the top of the baffle 465 is flush with the sliding surface of the spiral disk 47, and the fertilizer slides down again until it encounters the next baffle 465. The fertilizer is blocked again and enters the interior of the transmission box 461, thereby evenly transmitting the total fertilizer to the interior of each transmission box 461, so that the amount of fertilizer inside each transmission box 461 is the same, and then the fertilizer distributed into each storage box 61 is the same, which effectively prevents the storage box 61 with too little fertilizer from not having enough fertilizer during fertilization, resulting in uneven fertilizer around the tree roots.
