Description

Technical Field

[0001] This invention relates to the field of seedling straightening technology, and in particular to a seedling straightening device for navel orange planting. Background Technology

[0002] Navel oranges are a nutritious and delicious fruit. If the trunk of a navel orange tree is crooked during its seedling stage, it is easy for the trunk to break when the tree is bearing fruit, resulting in economic losses.

[0003] Patent publication number CN214046900U discloses a seedling straightening aid device, relating to the field of garden equipment technology. This seedling straightening aid device includes a first straightening ring, with a second straightening ring positioned behind the first. A threaded pin is threaded through the front end of the first straightening ring, and the rear end of the threaded pin is threaded through the front end of the second straightening ring. Three straightening blocks are positioned between the first and second straightening rings. A straightening spring is fixedly connected to the ends of each of the three straightening blocks that are furthest from each other. The ends of the straightening springs furthest from the straightening blocks are fixedly connected to the inner walls of the first and second straightening rings, respectively. This patent uses a mounting plate inserted into the ground to limit the position of the support rod, the first straightening ring, and the second straightening ring. However, due to the limited depth of the mounting plate, displacement easily occurs when installed on relatively soft soil, resulting in poor stability of the support rod and affecting the straightening effect on the seedlings.

[0004] In conclusion, there is a need to develop a seedling straightening device for navel orange cultivation that can provide support in soft soil and improve the stability of seedling uprighting. Summary of the Invention

[0026] Furthermore, it also includes a strengthening mechanism for straightening the upper and lower parts of the seedling, the strengthening mechanism including:

[0027] The guide frame, the second support frame, and the inner side of the first support frame are all connected to the guide frame;

Then, a screw rotates, causing the first straightening plate to move inwards to straighten the seedling. Simultaneously, a pulley and a flat belt drive a gear to rotate, causing a rack rod to press and push the block downwards, opening the fixing claws. This increases the support range of the fixing claws, improves the stability of the support column, and thus enhances the straightening effect on the seedling. Furthermore, a guide rod moves inwards, pushing the first rotating rod to rotate and erect the second straightening plate. This allows the second and first straightening plates to work together to provide three-point support for the seedling. The straightening of the line improves the effectiveness of straightening the seedlings; inserting the auxiliary rod into the ground further enhances the stability of the support column, thus improving the seedling straightening effect; pressing the support switch and moving it downwards causes the support switch to drive the second rotating rod and the lightweight support plate to rotate upwards and tilt, thus supporting the spreading branches of the seedlings and preventing the seedlings from bending due to uneven weight distribution; under the reset action of the second spring, the sliding block moves downwards and engages in the limiting groove, thus locking the first and second support frames, improving the stability of the fixing claw when inserted into the ground, and reducing operational hassle.

Detailed Implementation

[0061] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0062] Example 1

[0063] A seedling straightening device for navel orange cultivation, such as Figures 1-5 and Figure 12 As shown, the system includes support columns 1, fixing claws 2, first support frames 3, second support frames 31, third support frames 32, hinges 33, a straightening mechanism 4, and a fixing mechanism 5. There are three support columns 1. The left and right sides of the rear middle of the front support column 1 are connected to the two rear support columns 1 via the first support frames 3. The rear of the left first support frame 3 is connected to the left rear support column 1 via hinges 33. The front of the right first support frame 3 is connected to the front support column 1 via hinges 33. The right side of the left support column 1 is fixed to the right side of the second support frame 31. The left side of the right support column 1 is connected to the third support frame 32 via hinges 33. The right side of the second support frame 31 is connected to the third support frame 32. The support frame 32 is snapped on the left side. Three fixed claws 2 are evenly spaced at the bottom of each of the three first support frames 3. The fixed claws 2 are used to improve the stability of the support column 1. A straightening mechanism 4 is provided on the two first support frames 3 and the second support frame 31. The straightening mechanism 4 is used to straighten the seedling. A fixing mechanism 5 is provided between the support column 1 and the first support frame 3 and the second support frame 31. The fixing mechanism 5 is used to squeeze and open the fixed claws 2. The straightening mechanism 4 includes a lead screw 41, a first spring 42, a first straightening plate 43, and a guide rod 44. The two first support frames 3 are threadedly connected to the middle of the lead screw 41, and the second support frame 31 is threadedly connected to the right side of the lead screw 41. Each of the three rods 41 has a first straightening plate 43 slidably connected to its inner side. The first straightening plate 43 is used to straighten the seedling. Each of the three first straightening plates 43 is connected to a first spring 42 between it and a nearby lead screw 41. Each of the three first straightening plates 43 has two guide rods 44 fixedly connected to its outer side. The guide rods 44 are slidably connected to a nearby first support frame 3 and a second support frame 31, respectively. The fixing mechanism 5 includes a pulley 52, a flat belt 53, a gear 54, a rack 55, and a push block 56. Each of the three lead screws 41 has a square groove 51 at its top. Each of the three support columns 1 has a gear 54 rotatably connected to its lower part. Each of the three gears 54 has a pulley 52 fixedly connected to its rear side. 2. Both the middle of the two first support frames 3 and the right side of the second support frame 31 are rotatably connected to pulleys 52. The pulleys 52 on the first support frame 3 and the second support frame 31 are both annular and have a protruding inner top. The pulleys 52 on the first support frame 3 and the second support frame 31 are all sleeved on the adjacent lead screws 41 and slidably connected to the square grooves 51. Flat belts 53 are wound around the two pulleys 52 on the left, the two pulleys 52 on the right and the two pulleys 52 on the rear. The lower part of the three support columns 1 is slidably connected to rack rods 55. The bottom of the three rack rods 55 is fixedly connected to push blocks 56. Push blocks 56 are used to squeeze the fixed claws 2 to open.

[0064] In use, the operator manually unfolds the three support columns 1. The first support frame 3 and the third support frame 32 rotate and unfold under the action of the hinge 33. Then, the support columns 1 surround the seedling that needs to be straightened, so that the second support frame 31 and the third support frame 32 are engaged. Then, the fixing claw 2 contacts the ground and is inserted into the ground. In this way, the support column 1 is fixed, and the first support frame 3, the second support frame 31, and the third support frame 32 cooperate with the support column 1 to surround and straighten the seedling. Then, the screw 41 is manually rotated. The screw 41 moves inward, which drives the first straightening plate 43 and the guide rod 44 to move inward, so that the first straightening plate 43 contacts the seedling, thereby straightening the seedling. The first spring 42 acts as a buffer to prevent the seedling from being squeezed and damaged. When the screw 41 rotates, it drives the pulley 52 and the flat belt 53 to rotate. Under the action of the square groove 51, the pulley 52 can slide on the screw 41. The gear 54 rotates, which in turn drives the rack 55 to move downwards. The rack 55 then presses against the push block 56, causing it to move downwards. Since navel orange trees thrive in loose, porous soil with good drainage and aeration, the push block 56 can press the fixing claw 2 to rotate outwards and unfold. This increases the support range of the fixing claw 2, thereby improving the stability of the support column 1 and enhancing the effect of straightening the seedlings. When dismantling is required, the screw 41 is reversed, moving outwards and causing the first straightening plate 43 and guide rod 44 to move outwards and reset. Simultaneously, the screw 41 drives the pulley 52, flat belt 53, and gear 54 to reverse and reset, thereby causing the rack 55 and push block 56 to move upwards and reset, so that the push block 56 no longer blocks the fixing claw 2. Then, the workers pull up the support column 1, remove the fixing claw 2 from the ground, and unfold the first support frame 3, the second support frame 31, the third support frame 32, and the support column 1 to complete the dismantling.

[0065] Example 2

[0066] Based on Example 1, such as Figure 1 and Figure 6As shown, it also includes a strengthening mechanism 6, which is used to straighten the upper and lower parts of the seedling. The strengthening mechanism 6 includes a guide frame 61, a first moving rod 62, a first rotating rod 63, and a second straightening plate 64. Two guide frames 61 are fixedly connected to the inner side of the second support frame 31 and the two first support frames 3. The first moving rod 62 is slidably connected to the inner side of each guide frame 61. The first rotating rod 63 is rotatably connected to the inner side of each first moving rod 62 through a pin. Each first rotating rod 63 passes through the adjacent guide rod 44 and is rotatably connected to the guide rod 44. The second straightening plate 64 is fixedly connected to each first rotating rod 63. The second straightening plate 64 is used to straighten the upper and lower parts of the seedling. When the guide rod 44 moves inward, it pushes the first rotating rod 63 to rotate inward, thereby causing the second straightening plate 64 to rotate inward. This allows the second straightening plate 64 and the first straightening plate 43 to work together in a three-point alignment to straighten the seedling. In this way, the upper and lower parts of the seedling can be supported and straightened, thereby improving the straightening effect. When the guide rod 44 moves outward, it causes the first rotating rod 63 and the second straightening plate 64 to reverse and reset, so that the second straightening plate 64 no longer straightens the seedling.

[0067] like Figure 1 and Figure 7 As shown, it also includes an auxiliary mechanism 7, which is used to improve the stability of the support column 1. The auxiliary mechanism 7 includes an auxiliary rod 71, a fixed shaft 72, a rotating block 73, and a screw 74. The two first support frames 3 and the second support frame 31 are both fixedly connected to the outer side of the fixed shaft 72. Each fixed shaft 72 is rotatably connected to a rotating block 73. Each rotating block 73 is threadedly connected to a screw 74. Each rotating block 73 is slidably connected to an auxiliary rod 71. The auxiliary rod 71 is used to improve the stability of the support column 1. After inserting the fixing claw 2 into the ground, the worker manually turns the screw 74 to loosen the rotating block 73. Then, the worker manually controls the auxiliary rod 71 to rotate, causing the rotating block 73 to rotate. The worker then manually moves the auxiliary rod 71 down until it contacts the ground. Then, the worker uses a tool to tap the auxiliary rod 71 until it is inserted into the ground. This improves the stability of the support column 1. When it needs to be removed, the worker uses a tool to pull the auxiliary rod 71 out of the ground. Then, the worker turns the rotating block 73 to make the auxiliary rod 71 rotate parallel to the ground. Then, the worker turns the screw 74 to limit the rotation block 73. In this way, the auxiliary rod 71 can be retracted.

[0068] like Figure 1 , Figure 8 , Figure 9 and Figure 10As shown, it also includes a support mechanism 8, which is used to support the spreading branches of the seedling. The support mechanism 8 includes a support switch 81, a second moving rod 82, a second rotating rod 83, a lightweight support plate 84, a rotating bracket 85, a clamping bracket 86, and a bidirectional telescopic block 87. The support switch 81 is slidably connected to the upper part of each of the three support columns 1. The clamping bracket 86 is fixedly connected to the inner side of the top of each of the three support switches 81. The clamping bracket 86 is located inside the support column 1 and slidably connected to the support column 1. The bidirectional telescopic block 87 is slidably connected to the lower part of each clamping bracket 86. The bidirectional telescopic block 87 is used to position the support switch 81. Each bidirectional telescopic locking block 87 is connected to a spring. The outer side of the bidirectional telescopic locking block 87 is made of rubber. Each support switch 81 has two second moving rods 82 fixedly connected to the top inner side. The second moving rods 82 are located inside the clamping bracket 86 and are slidably connected to the support column 1. Each support column 1 has two rotating brackets 85 fixedly connected to the upper part. Each rotating bracket 85 is fitted with a second rotating rod 83. The upper parts of the two second moving rods 82 in the same support column 1 are rotatably connected to the adjacent second rotating rods 83. Each second rotating rod 83 has a lightweight support plate 84 fixedly connected to the inner side. The lightweight support plate 84 is used to support the spreading branches of the seedling. Initially, the bidirectional telescopic locking block 87 is in contact with the support column 1, and both the bidirectional telescopic locking block 87 and its internal spring are in a compressed state. Because the outer side of the bidirectional telescopic locking block 87 is made of rubber, the friction between the bidirectional telescopic locking block 87 and the support column 1 is relatively large. When the seedling grows and branches out, the operator can manually press the support switch 81 to move it downwards. The support switch 81 moves the locking bracket 86 and the bidirectional telescopic rod downwards. When the support switch 81 moves downwards, it moves the second moving rod 82 downwards. The second moving rod 82 causes the outer side of the second rotating rod 83 to swing downwards, causing the inner side of the second rotating rod 83 to swing upwards, thereby... The lightweight support plate 84 is tilted upwards to support the spreading branches of the seedling, preventing the seedling from bending due to uneven weight distribution. Then, the support switch 81 is released, and the bidirectional telescopic locking block 87 is engaged within the support column 1 to limit the clamping bracket 86, thereby limiting the lightweight support plate 84. When disassembly is required, the support switch 81 is manually lifted upwards to reset, causing the clamping bracket 86 and the bidirectional telescopic locking block 87 to move upwards to reset, thereby causing the second moving rod 82 to move upwards to reset, and causing the second rotating rod 83 and the lightweight support plate 84 to reverse and reset.

[0069] like Figure 1 and Figure 11As shown, it also includes a locking mechanism 9, which is used to lock the third support frame 32 and the second support frame 31. The locking mechanism 9 includes a sliding block 91 and a second spring 92. Limiting grooves 93 are opened on the right side of the second support frame 31 and the left side of the third support frame 32. The sliding block 91 is slidably connected to the left side of the third support frame 32. The sliding block 91 is used to lock the third support frame 32 and the second support frame 31. The second spring 92 is connected between the bottom of the sliding block 91 and the third support frame 32. The left side of the sliding block 91 is locked in the limiting groove 93 that connects the third support frame 32 and the second support frame 31. When the seedling needs to be enclosed using the first support frame 3, the second support frame 31, and the third support frame 32, the worker manually pulls the sliding block 91 upwards. The second spring 92 is stretched, causing the sliding block 91 to separate from the limiting groove 93. This prevents the third support frame 32 and the second support frame 31 from being locked in place. Then, the first support frame 3, the second support frame 31, and the third support frame 32 are opened to enclose the seedling. When the third support frame 32 and the second support frame 31 are engaged, the limiting groove 93 is connected. Then, the sliding block 91 is released, and the second... Spring 92 returns to its original position, causing sliding block 91 to move downwards and engage with the limiting groove 93 that connects the third support frame 32 and the second support frame 31. This engages the first support frame 3, the second support frame 31, and the third support frame 32, improving their stability and preventing them from loosening when the fixing claw 2 is inserted into the ground. This reduces operational hassle, and the above operation can be repeated when disassembly is required.

[0070] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
