Description

Technical Field

[0001] This invention relates to the field of seedling equipment, specifically to a forestry planting device that can automatically remove seedlings. Background Technology

[0002] Seedling cultivation, or the raising of seedlings, is crucial in the growth of forest trees. Directly sowing forest seeds in the wild results in a very low survival rate. Therefore, to improve the survival rate of afforestation and save on costs, forestry planting equipment is needed to cultivate seedlings. After successful seedling cultivation, existing equipment requires transplanting the seedlings to the ground. This is usually done manually by shoveling soil and then pulling the seedlings out. However, manual shoveling is prone to damage to the roots due to improper force, and the seedlings may break during subsequent pulling, leading to waste.

[0003] Publication number CN115804325A discloses a forestry planting device for automatically removing seedlings, including a planting pot, a conical gear ring, a gear ring, a bevel gear, a rocker arm, a pinion, and a spiral drill rod. Rotating the rocker arm causes the bevel gear to mesh with the conical gear ring, which in turn causes the pinion and the spiral drill rod to revolve around the center of the planting pot. Simultaneously, the pinion gear meshes with the gear ring, causing the spiral drill rod to rotate, thus loosening the soil evenly inside the planting pot. However, while this device effectively loosens the soil through the rotation and revolution of the spiral drill rod, the rotation itself can easily entangle small roots and stems, and the excessive distance traveled during revolution can cause root and stem breakage, affecting the survival rate of transplanted seedlings.

[0004] Based on this, the present invention is proposed. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] Furthermore, the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0053] like Figure 1As shown, the forestry planting device for automatically removing seedlings includes: a seedling cylinder 1, a middle cylinder 2, a surrounding mechanism 3, a lifting mechanism 4, a clamping mechanism 5, a dispersing mechanism 6, and a driving mechanism 7. The seedling cylinder 1 is a hollow cylindrical body with an open top, filled with nutrient soil for cultivating seedlings. The middle cylinder 2 is installed at the center of the seedling cylinder 1 and is also a hollow cylindrical structure with an open top. Six crossbeams 201 are arranged circumferentially within the cavity of the seedling cylinder 1, with both ends of the crossbeams 201 fixedly connected to the inner wall of the seedling cylinder 1 and the outer wall of the middle cylinder 2, respectively. The horizontal frame 201 acts as a fixing component to ensure the fixed installation of the central cylinder 2. The horizontal frame 201 is located at the top of the inner cavity of the seedling cylinder 1. The area between two adjacent horizontal frames 201 is an independent planting area for cultivating seedlings. The six horizontal frames 201 divide the seedling cylinder 1 into six equidistant, circumferentially spaced independent planting areas for seedling cultivation. Simultaneously, the area at the bottom of the horizontal frames 201 in the seedling cylinder 1 is a fully connected space, ensuring that seedlings in each area can share soil nutrients and water. A surrounding mechanism 3 is installed on the side wall of the seedling cylinder 1, a lifting mechanism 4 is installed at the top of the surrounding mechanism 3, and a clamping mechanism 5 is installed on the lifting mechanism 4. The clamping mechanism 5 is controlled to clamp the seedlings, and the lifting mechanism 4 can adjust the height of the clamping mechanism 5 to align it with the seedling height. After clamping the seedling, the clamping mechanism 5 can pull the seedling upwards. The surrounding mechanism 3 is also controlled to adjust the circumferential position of the lifting mechanism 4 to align with seedlings at different locations.

[0054] refer to Figure 2 and Figure 3 The surrounding mechanism 3 includes: a gear ring 31, a movable seat 32, a limiting wall 33, a gear 34, and a first motor 35. The gear ring 31 is installed on the outer wall of the seedling cylinder 1. The movable seat 32 is located on the side of the seedling cylinder 1. There are two limiting walls 33, which are symmetrically installed at the upper and lower ends of the movable seat 32, and the opposite sides of the two limiting walls 33 away from the movable seat 32 are slidably engaged with the upper and lower ends of the gear ring 31. Specifically, the gear ring 31 has a slide rail, and the limiting wall 33 has a slider. The slider is slidably installed in the slide rail to ensure that the movable seat 32 and the limiting wall 33 can be stably set as a whole. The movable seat 32 is a hollow structure, and the gear 34 is rotatably installed inside the movable seat 32, and the gear 34 is meshed with the gear ring 31. The first motor 35 is installed on the movable seat 32, and the output end of the first motor 35 is connected to the gear 34. Turning on the first motor 35 drives the gear 34 to rotate, and the meshing of the gear 34 with the gear ring 31 ensures that the moving seat 32 can perform circular motion. In addition, the first motor 35 in this embodiment is a self-locking motor, and the output end can be locked to fix the position of the moving seat 32.

[0055] refer to Figure 2 and Figure 3The lifting mechanism 4 includes a mounting frame 41, a second motor 42, a lead screw 43, and a lifting platform 44. The mounting frame 41 is mounted on the upper surface of the movable seat 32. The second motor 42 is mounted on the top of the mounting frame 41. The two ends of the lead screw 43 are rotatably connected to the movable seat 32 and the mounting frame 41, respectively, and the output end of the second motor 42 is connected to the top of the lead screw 43. Turning on the second motor 42 can drive the lead screw 43 to rotate. The lifting platform 44 is slidably mounted on the mounting frame 41 in the vertical direction, and the lifting platform 44 is threadedly connected to the lead screw 43. When the lead screw 43 rotates, the lifting platform 44 can move along the axial direction of the lead screw 43, and with the mutual limiting of the mounting frame 41 and the lifting platform 44, the stable lifting of the lifting platform 44 can be achieved.

[0056] refer to Figure 4 , Figure 5 and Figure 6The clamping mechanism 5 includes: a connecting frame 51, a translation rod 52, a push rod 53, a first electric push rod 54, a limiting groove 55, a limiting block 56, a slide block 57, a first connecting rod 58, a clamping arm 59, a second electric push rod 510, an extension arm 511, a slide arm 512, a card seat 513, a clamping piece 514, and a second connecting rod 515. The connecting frame 51 is installed on the side of the lifting platform 44 facing the seedling cylinder 1. There are two translation rods 52, which are symmetrically installed on the connecting frame 51 and slidably connected to the connecting frame 51. The push rod 53 is installed inside the connecting frame 51, and the first electric push rod 54 is installed on the connecting frame 51, with the output end of the first electric push rod 54 connected to the push rod 53. Activating the first electric push rod 54 can drive the push rod 53 to move within the connecting frame 51. The first electric push rod 54 is a self-locking electric push rod, and its output end can be locked in any position. There are two limiting grooves 55, symmetrically formed on the inner walls of both sides of the connecting frame 51. There are two limiting blocks 56, respectively installed at both ends of the push rod 53, and the two limiting blocks 56 are slidably installed in the two limiting grooves 55. The cooperation of the limiting grooves 55 and the limiting blocks 56 ensures the stable movement of the push rod 53. There are two slide blocks 57, symmetrically slidably installed on the push rod 53. The two ends of the first connecting rod 58 are rotatably installed on the slide block 57 and the translation rod 52, respectively. The two ends of the second connecting rod 515 are rotatably installed on the slide block 57 and the connecting frame 51, respectively. When the first electric push rod 54 is activated, it pushes the push rod 53 towards the translation rod 52. Using the rotational cooperation of the first connecting rod 58 and the second connecting rod 515, the two translation rods 52 can move closer to each other. When the output end of the first electric push rod 54 retracts, the two translation rods 52 move away from each other. There are two clamping arms 59, respectively installed at opposite ends of the two translation rods 52. An extension arm 511 is slidably mounted on a clamping arm 59. A sliding arm 512 is mounted on opposite sides of the two clamping arms 59. A retainer 513 is mounted on the extension arm 511 and slidably engages with the sliding arm 512. This combination ensures that the extension arm 511 can slide stably relative to the axis of the clamping arms 59. A clamping plate 514, made of rubber, is mounted on the extension arm 511. When the two extension arms 511 clamp the seedling, the rubber clamping plate 514 provides good friction against the seedling branches, ensuring stable clamping. The rubber material also has some elasticity, preventing damage to the seedling. Two second electric push rods 510 are installed on opposite sides of the two clamping arms 59, and their output ends are connected to the extension arms 511. The second electric push rods 510 are self-locking electric push rods, and their output ends can be locked in any position.

[0057] The working principle of the above structure is as follows: Nutrient soil is filled into the seedling cylinder 1, and seedlings are planted in each planting area. When automatic seedling removal is required, the gear 34 rotates when the first motor 35 is turned on, causing the moving seat 32 to move in a circular motion along the gear ring 31. This ensures that the clamping mechanism 5 is aligned with the seedling to be removed. Then, the second motor 42 is turned on, causing the lead screw 43 to rotate, thereby adjusting the height of the lifting platform 44. The second electric push rod 510 is activated, causing the extension arm 511 to extend and align with the seedling. The first electric push rod 54 is activated, causing the push rod 53 to move. Using the cooperation of the first connecting rod 58 and the second connecting rod 515, the two translation rods 52 are brought closer together, clamping the seedling. This, in conjunction with the lifting platform 44, allows the seedling to be removed.

[0058] refer to Figure 7 , Figure 8 , Figure 9 and Figure 10 The dispersing mechanism 6 is rotatably installed at the bottom of the inner cavity of the seedling tube 1, and the driving mechanism 7 is installed in the middle tube 2. The driving mechanism 7 is controlled to drive the dispersing mechanism 6 to rotate back and forth. The reciprocating rotation of the dispersing mechanism 6 can loosen the soil in the seedling tube 1, which is conducive to the pulling out of the seedlings and avoids pulling and breaking the root system.

[0059] The drive mechanism 7 includes: a rotating rod 71, a pressing cap 72, a turntable 73, a spring 74, a protrusion 75, a groove 76, a guide groove 77, and a guide block 78. The rotating rod 71 is rotatably mounted in the middle cylinder 2. The pressing cap 72 is mounted on the top of the rotating rod 71. The turntable 73 is rotatably mounted on the rotating rod 71, and the spring 74 is mounted between the rotating rod 71 and the turntable 73. The protrusion 75 is mounted on the inner wall of the middle cylinder 2, and the groove 76 is formed on the outer wall of the pressing cap 72. The protrusion 75 is slidably embedded in the groove 76. The cooperation between the protrusion 75 and the groove 76 ensures that the pressing cap 72 can only move vertically. As the pressing cap 72 descends, it compresses the spring 74. After the external force is removed, the spring force of the spring 74 allows the pressing cap 72 to return to its original position. The guide groove 77 is formed on the outer wall of the rotating rod 71 and is inclined along the outer wall of the rotating rod 71. A guide block 78 is installed on the inner wall of the pressing cap 72, and the guide block 78 is slidably embedded in the guide groove 77. In use, pressing down on the pressing cap 72 drives the guide groove 77 via the guide block 78, causing the rotating rod 71 to rotate, which in turn drives the distributing mechanism 6 to rotate. When the pressing cap 72 rises and resets under the force of the spring 74, the rotating rod 71 and the distributing mechanism 6 reverse and reset. During this process, the rotation of the turntable 73 ensures that the rotation of the rotating rod 71 does not affect the spring 74, preventing the spring 74 from twisting. In this embodiment, the central angles corresponding to the projections of the beginning and end of the guide groove 77 onto the horizontal plane correspond to the central angles corresponding to each individual planting area, ensuring that the rotation angle range of the rotating rod 71 corresponds to the individual planting area.

[0060] refer to Figure 11, Figure 12 , Figure 13 and Figure 14 The dispersing mechanism 6 includes: a rotating ring 61, a fixed arm 62, a first lever 63, a fixed ring 64, a swing arm 65, a second lever 66, a through groove 67, and a sliding rod 68. The rotating ring 61 is rotatably mounted in the seedling cylinder 1 and connected to the rotating rod 71. There are six fixed arms 62, equidistantly mounted on the rotating ring 61 along the circumference. The first lever 63 is mounted on the upper surface of the fixed arm 62. The fixed ring 64 is mounted on the bottom of the inner wall of the seedling cylinder 1. There are six swing arms 65, rotatably mounted on the fixed ring 64 along the circumference. The second lever 66 is mounted on the upper surface of the swing arm 65. The through groove 67 is formed on the swing arm 65, and the sliding rod 68 is mounted on the lower surface of the fixed arm 62, and slides within the through groove 67. When the rotating ring 61 reciprocates, the sliding rod 68, moving through the groove 67, causes the rocker arm 65 to swing back and forth. This, in turn, loosens the soil using the first lever 63 and the second lever 66. Furthermore, a gap exists between the second lever 66 and the adjacent first lever 63, corresponding to the center of the independent planting area. This ensures that when the seedling is planted in the center of the independent planting area, it is offset from the first lever 63 and the second lever 66, preventing the taproot from being disturbed when the first lever 63 and the second lever 66 swing back and forth to loosen the soil. In this embodiment, each fixed arm 62 and its corresponding rocker arm 65 corresponds to an independent planting area. When the rotating ring 61 reciprocates, the first lever 63 and the second lever 66 can only loosen the soil within their respective independent planting areas, avoiding loosening the soil across areas. This small-scale loosening also prevents the roots from being entangled and broken due to excessive movement. Furthermore, the swing trajectory of the first lever 63 is an arc, while the second lever 66 swings with radial displacement, which avoids poor soil loosening effect due to simple reciprocating movement in the arc direction and helps to improve the soil loosening effect.

[0061] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
