Description

Technical Field

[0001] The present invention relates to the field of seedling raising equipment, in particular to a forestry planting device capable of automatically pulling out seedlings. Background Art

[0002] Seedling cultivation refers to the cultivation of young trees. Seedling cultivation is crucial in the growth of trees. Direct sowing of tree seeds in the wild has a very low survival rate. Therefore, to improve the survival rate of afforestation and save afforestation costs, forestry planting equipment is needed to cultivate seedlings. Existing forestry planting equipment, after successful seedling cultivation, needs to transplant the seedlings to the ground. This is usually done manually, with soil shoveled and then pulled out for transplanting. However, manual shoveling can be difficult to control, causing root damage to the seedlings. Furthermore, the seedlings can be broken when pulled out, resulting in wasted seedlings.

[0003] Publication number CN115804325A discloses a forestry planting device that can automatically remove seedlings, including a planting basin, a bevel gear ring, a gear ring, a bevel gear, a rocker, a pinion, an auger rod, etc. When the rocker is rotated, the bevel gear engages the bevel gear ring, thereby driving the pinion and the auger rod to revolve around the middle of the planting basin. When the pinion rotates, it also engages the gear ring, causing the auger rod to rotate, thereby evenly loosening the soil inside the planting basin. However, although the device can loosen the soil through the rotation and revolution of the auger rod, it is easy for small roots to be entangled on the auger rod during rotation, and the revolution travel distance is too large, which can easily cause the roots to be pulled off, affecting the survival rate of the seedlings after transplantation.

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

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.

[0023] In this document, the term "and / or" simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0024] like Figure 1 As shown, the forestry planting device that can automatically remove seedlings includes: a seedling tube 1, a middle tube 2, a surrounding mechanism 3, a lifting mechanism 4, a clamping mechanism 5, a spreading mechanism 6 and a driving mechanism 7. The seedling tube 1 is a hollow cylindrical body with an open top, and its interior is filled with nutrient soil for cultivating seedlings. The middle tube 2 is installed at the center of the seedling tube 1, and the middle tube 2 is a hollow cylindrical structure with an open top. There are six cross frames 201, which are respectively arranged in the inner cavity of the seedling tube 1 along the circumferential direction, and the two ends of the cross frames 201 are fixedly connected to the inner wall of the seedling tube 1 and the outer wall of the middle tube 2 respectively. The cross frame 201 as a fixing member can ensure that the middle tube 2 is fixed, wherein the cross frame 201 is arranged at the top of the inner cavity of the seedling tube 1, and the area between two adjacent cross frames 201 is an independent planting area for cultivating seedlings. The seedling tube 1 can be divided into six independent planting areas for seedling cultivation and planting that are equidistant along the circumference by six cross frames 201. At the same time, the area at the bottom of the cross frame 201 in the seedling tube 1 is an overall connected space, which ensures that the seedlings in each area can share soil nutrients, water and other substances. The surrounding mechanism 3 is installed on the side wall of the seedling tube 1, the lifting mechanism 4 is installed on the top of the surrounding mechanism 3, and the 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 so that the clamping mechanism 5 can be aligned with the height of the seedlings, and when the clamping mechanism 5 clamps the seedlings, the seedlings can be pulled out upwards. The surrounding mechanism 3 is controlled to adjust the circumferential position of the lifting mechanism 4 to align with seedlings in different positions.

[0025] 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 tube 1. The movable seat 32 is arranged on the side of the seedling tube 1, and there are two limiting walls 33, which are symmetrically installed on the upper and lower ends of the movable seat 32, and the two limiting walls 33 are slidably engaged with the upper and lower ends of the gear ring 31 on the opposite sides away from one end of the movable seat 32. The specific engaging method is that the gear ring 31 is provided with a slide, and the limiting wall 33 is provided with a slider, and the slider is slidably installed in the slide to ensure that the movable seat 32 and the limiting wall 33 can be stably arranged as a whole. Among them, the movable seat 32 is a hollow structure, the gear 34 is rotatably installed in 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 can drive the gear 34 to rotate, and then the meshing of the gear 34 and the gear ring 31 ensures that the movable base 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 movable base 32.

[0026] refer to Figure 2 and Figure 3 The 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 up and down directions, 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 cooperate with the mutual limitation of the mounting frame 41 and the lifting platform 44 to realize the stable lifting and lowering of the lifting platform 44.

[0027] refer to Figure 4 、 Figure 5 and Figure 6The clamping mechanism 5 includes: a connecting frame 51, a translation rod 52, a propulsion rod 53, a first electric push rod 54, a limiting groove 55, a limiting block 56, a sliding seat 57, a first connecting rod 58, a clamping arm 59, a second electric push rod 510, an extension arm 511, a sliding arm 512, a clamping 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 tube 1. There are two translation rods 52, which are symmetrically installed on the connecting frame 51 and are slidably connected to the connecting frame 51. The propulsion rod 53 is installed in the connecting frame 51, and the first electric push rod 54 is installed on the connecting frame 51, and the output end of the first electric push rod 54 is connected to the propulsion rod 53. Turning on the first electric push rod 54 can drive the propulsion rod 53 to move in the connecting frame 51. The first electric push rod 54 uses a self-locking electric push rod, and its output end can be locked at any position. There are two symmetrical limit slots 55 on the inner walls of the connecting frame 51. There are two limit blocks 56, one mounted on each end of the push rod 53. The two limit blocks 56 slide in the two limit slots 55, ensuring stable movement of the push rod 53. There are two slides 57, symmetrically mounted on the push rod 53. The two ends of the first connecting rod 58 are rotatably mounted on the slide 57 and the translation rod 52. The two ends of the second connecting rod 515 are rotatably mounted on the slide 57 and the connecting frame 51. When the first electric push rod 54 is activated, it pushes the push rod 53 toward the translation rod 52. The rotational coordination of the first connecting rod 58 and the second connecting rod 515 allows the two translation rods 52 to move closer together. 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, mounted on opposite ends of the two translation rods 52. The extension arm 511 is slidably mounted on the clamping arm 59, and the sliding arm 512 is mounted on opposite sides of the two clamping arms 59. The clamping seat 513 is mounted on the extension arm 511 and is slidably engaged with the sliding arm 512. The combination of the two ensures that the extension arm 511 can slide stably relative to the axis of the clamping arm 59. The clamping piece 514 is mounted on the extension arm 511. The clamping piece 514 is made of rubber. When the two extension arms 511 clamp the seedlings, the rubber clamping piece 514 is close to the branches of the seedlings and can provide good friction to ensure stable clamping. At the same time, the rubber material has a certain elasticity to avoid damaging the seedlings. There are two second electric push rods 510, one mounted on the opposite side of the two clamping arms 59, and the output end of the second electric push rod 510 is connected to the extension arm 511. The second electric push rod 510 is a self-locking electric push rod, and its output end can be locked in any position.

[0028] The working principle of the above structure is as follows: the seedling tube 1 is filled with nutrient soil, and seedlings are planted in each planting area. When the seedlings need to be automatically pulled out, the gear 34 rotates when the first motor 35 is turned on, and the movable seat 32 performs a circular motion along the gear ring 31. Ensure that the clamping mechanism 5 is aligned with the seedlings to be pulled out. Then turn on the second motor 42 to rotate the lead screw 43, and then adjust the height of the lifting platform 44. Turn on the second electric push rod 510 to extend the extension arm 511 to correspond to the seedlings. Turn on the first electric push rod 54 to move the propulsion rod 53, and use the cooperation of the first connecting rod 58 and the second connecting rod 515 to make the two translation rods 52 approach each other so that the seedlings are clamped. Then cooperate with the lifting platform 44 to pull out the seedlings.

[0029] refer to Figure 7 、 Figure 8 、 Figure 9 and Figure 10 The spreading mechanism 6 is rotatably installed at the bottom end 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 spreading mechanism 6 to rotate back and forth as a whole. The reciprocating rotation of the spreading mechanism 6 can loosen the soil in the seedling tube 1, which is conducive to the extraction of seedlings and avoids pulling the roots apart by hard pulling.

[0030] The drive mechanism 7 comprises a rotating rod 71, a push cap 72, a rotating disk 73, a spring 74, a projection 75, a groove 76, a guide slot 77, and a guide block 78. The rotating rod 71 is rotatably mounted within the middle cylinder 2. The push cap 72 is mounted on the top of the rotating rod 71. The rotating disk 73 is rotatably mounted on the rotating rod 71, with the spring 74 mounted between the rotating rod 71 and the rotating disk 73. The projection 75 is mounted on the inner wall of the middle cylinder 2, and the groove 76 is provided on the outer wall of the push cap 72. The projection 75 slides within the groove 76. The interaction between the projection 75 and the groove 76 ensures that the push cap 72 can only move in the up-and-down direction. As the push cap 72 descends, it compresses the spring 74. When the external force is removed, the spring 74 returns the push cap 72 to its original position. The guide slot 77 is provided on the outer wall of the rotating rod 71 and is arranged obliquely along the outer wall of the rotating rod 71. The 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. When in use, the pressing cap 72 is pressed downward, and the guide block 78 drives the guide groove 77 to rotate the rotating rod 71, thereby driving the sowing mechanism 6 to rotate. When the pressing cap 72 rises and resets under the elastic force of the spring 74, the rotating rod 71 and the sowing mechanism 6 reverse and reset. In this process, the rotation of the turntable 73 can ensure that the rotation of the rotating rod 71 does not affect the spring 74, thereby preventing the spring 74 from twisting. In this embodiment, the central angle corresponding to the projection of the head and tail of the guide groove 77 on the horizontal plane corresponds to the central angle corresponding to each individual planting area, ensuring that the rotation angle range of the rotating rod 71 corresponds to the individual planting area.

[0031] refer to Figure 11、 Figure 12 、 Figure 13 and Figure 14 The spreading 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 slot 67 and a slide bar 68. The rotating ring 61 is rotatably mounted in the seedling tube 1 and is connected to the rotating rod 71. There are six fixed arms 62, which are equidistantly mounted on the rotating ring 61 along the circumferential direction. The first lever 63 is mounted on the upper surface of the fixed arm 62. The fixed ring 64 is mounted on the bottom end of the inner wall of the seedling tube 1. There are six swing arms 65, which are rotatably mounted on the fixed ring 64 along the circumferential direction at equal distances. The second lever 66 is mounted on the upper surface of the swing arm 65. The through slot 67 is opened on the swing arm 65, the slide bar 68 is mounted on the lower surface of the fixed arm 62, and the slide bar 68 is slidably mounted in the through slot 67. When the rotating ring 61 rotates back and forth, the movement of the slide bar 68 in the through slot 67 causes the swing arm 65 to swing back and forth, thereby loosening the soil through the movement of the first and second levers 63 and 66. Furthermore, a gap is left between the second lever 66 and the adjacent first lever 63. This gap corresponds to the center position of the independent planting area, ensuring that the seedlings planted in the center position of the independent planting area can be offset from the first and second levers 63 and 66, ensuring that the taproots can be avoided when the first and second levers 63 and 66 swing back and forth to loosen the soil. In this embodiment, each fixed arm 62 and the corresponding swing arm 65 correspond to an independent planting area. When the rotating ring 61 rotates back and forth, the first and second levers 63 and 66 can only loosen the soil in a small area within their respective independent planting areas, avoiding loosening across an area. This small area of ​​loosening can also prevent roots from being entangled and broken due to excessive movement. The first lever 63 swings in an arc trajectory, while the second lever 66 swings while undergoing radial displacement, thereby avoiding poor soil loosening effects caused by simple reciprocating movement in the arc direction and helping to improve the soil loosening effect.

Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions may be made based on design requirements and other factors.
