Description

Technical Field

[0001] This utility model relates to a straightening frame, and more particularly to a straightening frame for corn planting. Background Technology

[0002] A trellis supports the corn stalks, keeping them upright. This upright position helps the leaves absorb sunlight and rainwater more effectively, thus improving photosynthetic efficiency and promoting the growth and development of the corn. Furthermore, a trellis effectively protects the corn from wind, rain, and other natural elements, preventing lodging and reducing yield losses caused by lodging.

[0003] For example, a corn planting support frame with announcement number CN218680476U includes: a limiting plate, two limiting plates, a sliding groove on the upper side of the two limiting plates, several limiting holes along the direction of the sliding groove on one side of the limiting plate, a slider sliding in the sliding groove, a lifting rod connected to the top of the slider, a fixing plate connected to the side of the lifting rod near the limiting hole, a bolt that mates with the limiting hole connected to the fixing plate, a connector and a connecting sleeve on the front and rear sides of the two lifting rods respectively, and a support assembly connecting the two lifting rods.

[0004] Although the aforementioned patents offer a wide range of size adjustment between the support sleeves, making them highly applicable, and the lifting rods can adjust the height of the uprighting frame without damaging the corn, and the size adjustment is controllable and applicable to different situations, each uprighting frame can only support one corn stalk. In high-density planting environments, the process of installing and dismantling these uprighting frames is cumbersome, significantly increasing the workload and affecting operational efficiency. Utility Model Content

[0005] In order to overcome the shortcomings of the existing uprighting frame, which requires a large amount of work for installation and dismantling, the technical problem of this utility model is to provide an uprighting frame for corn planting.

[0006] The technical solution is: a corn planting support frame, including an installation frame, a telescopic frame and a positioning frame. Two installation frames are symmetrically arranged at both ends of the telescopic frame. The upper side of the installation frame is slidably connected to the telescopic frame, and the lower side is rotatably connected to the telescopic frame. Multiple positioning frames are evenly and symmetrically arranged on the front and rear sides of the telescopic frame.

[0007] Furthermore, it also includes a guide rod, a limiting clamp, a first bolt, a second bolt, and a limiting plate. The positioning frame is connected to the guide rod. The limiting clamp includes a guide sleeve, a fixed clamping block, a movable clamping block, and a locking ring. The guide rod is slidably provided with a guide sleeve. The first bolt is threadedly connected to the guide sleeve. The fixed clamping block is connected to the guide sleeve. The movable clamping block is rotatably mounted on the fixed clamping block. Locking rings are connected to opposite sides of both the fixed clamping block and the movable clamping block. A pin is slidably connected to the center of the locking ring. The limiting plate is slidably connected inside the movable clamping block. The second bolt is threadedly connected to the movable clamping block and is rotatably connected to the limiting plate.

[0008] Furthermore, it also includes sponge blocks, with sponge blocks provided on the inner side of the fixing block and on the side of the limiting plate facing the fixing block.

[0009] Furthermore, it also includes a bearing seat, a winding wheel, a binding rope, and a limiting ring. Two bearing seats and a limiting ring are provided in the middle of the mounting bracket on one side. A winding wheel is rotatably provided between the two bearing seats. A spring is installed between the winding wheel and the bearing seat. A binding rope is wound on the winding wheel. One end of the binding rope is provided with a hook that matches the limiting ring.

[0010] Furthermore, it also includes positioning tops, with both mounting brackets having sliding positioning tops at the bottom.

[0011] Furthermore, it also includes a connecting rope, which is located on the top of the positioning frame and connected to the lower part of the mounting frame.

[0012] Furthermore, it also includes a bearing housing, connecting rods, telescopic rods, rollers, and elastic elements. One of the mounting brackets has a bearing housing on its top, and connecting rods are symmetrically arranged at both ends of the bearing housing. Telescopic rods are slidably arranged on both connecting rods. The rollers are rotatably connected between the two telescopic rods. One end of the elastic element is connected to the connecting rod, and the other end is connected to the telescopic rod.

[0013] Furthermore, both mounting brackets are equipped with interlocking slots.

[0014] Beneficial effects: 1. This utility model, through the design of the telescopic frame, realizes flexible adjustment according to the corn planting spacing, avoiding the tedious process of installing and disassembling each traditional upright frame, and saving time for fixing the corn.

[0015] 2. This utility model also provides stable support when fixing corn stalks through the design of components such as limiting clips and sponge blocks, while avoiding damage to the corn stalks. The use of sponge blocks not only increases the contact area with the corn stalks and improves the stability of the fixation, but also, due to their soft properties, will not put pressure on or scratch the stalks, thus protecting the growth of the corn.

Detailed Implementation

[0023] A type of uprighting frame for corn planting, such as Figure 1 As shown, it includes an installation frame 1, a telescopic frame 2, and a positioning frame 3. The two installation frames 1 are symmetrically arranged at both ends of the telescopic frame 2. The telescopic frame 2 is a scissor-type telescopic frame. The upper side of the installation frame 1 is slidably connected to the telescopic frame 2, and the lower side is rotatably connected to the telescopic frame 2. Multiple positioning frames 3 are evenly and symmetrically arranged on the front and rear sides of the telescopic frame 2. In use, the telescopic frame 2 is adjusted according to the spacing of the corn planting, and then the lower part of the positioning frame 3 is inserted into the soil according to the adjusted spacing. Then, the corn stalks are tied together with the positioning frame 3 with rope.

[0024] To replace the function of rope, such as Figure 2 and Figure 3As shown, it also includes a guide rod 4, a limiting clamp 5, a first bolt 6, a second bolt 7, and a limiting plate 8. The positioning frame 3 is connected to the guide rod 4. The limiting clamp 5 includes a guide sleeve 51, a fixed clamping block 52, a movable clamping block 53, and a locking ring 10. The guide rod 4 is slidably provided with the guide sleeve 51, and the first bolt 6 is threadedly connected to the guide sleeve 51. Tightening the first bolt 6 can fix the guide sleeve 51 to the guide rod 4. The fixed clamping block 52 is connected to the guide sleeve 51. The movable clamping block 53 is rotatably installed on the fixed clamping block 52. The fixed clamping block 52 and the movable clamping block 53 are both connected to the opposite side of the fixed clamping block 52 and the movable clamping block 53. The two locking rings 10 are staggered in height. The limiting plate 8 is slidably connected inside the movable clamping block 53. The second bolt 7... The screw is connected to the movable clamping block 53, and the second bolt 7 passes through the movable clamping block 53. The second bolt 7 is rotatably connected to the limiting plate 8. When fixing the corn stalk, first loosen the first bolt 6, then move the limiting clamp 5 to a suitable position on the guide rod 4 and retighten the first bolt 6. Rotate the movable clamping block 53 to separate the locking ring 10 on the fixed clamping block 52 and the movable clamping block 53. Then place the corn stalk between the two sponge blocks 9. Next, rotate the movable clamping block 53 until the two locking rings 10 are aligned. Then take a pin and insert it into the two locking rings 10 to fix the movable clamping block 53 and the fixed clamping block 52. By adjusting the second bolt 7 to drive the limiting plate 8 to move, the corn stalk can be clamped to achieve a stable fixation.

[0025] like Figure 2 and Figure 3 As shown, it also includes a sponge block 9. The inner side of the fixing clamp 52 and the side of the limiting plate 8 facing the fixing clamp 52 are both provided with sponge blocks 9. The sponge blocks 9 can reduce the damage caused when fixing the corn stalks.

[0026] like Figure 4 As shown, it also includes a bearing seat 11, a winding wheel 12, a binding rope 13, and a limiting ring 14. The mounting frame 1 on one side has two bearing seats 11 and a limiting ring 14 in the middle. The winding wheel 12 is rotatably mounted between the two bearing seats 11. A spring 111 is installed between the winding wheel 12 and the bearing seat 11. The binding rope 13 is wound on the winding wheel 12. One end of the binding rope 13 is connected to the winding wheel 12, and the other end has a hook that matches the limiting ring 14. When the upright frame needs to be retracted after use, first retract the telescopic frame 2, then pull out the binding rope 13 and use the binding rope 13 to tie the telescopic frame 2. Finally, use the hook at one end of the binding rope 13 to hook the limiting ring 14. When the upright frame needs to be used, remove the hook on the limiting ring 14, and the spring 111 will drive the binding rope 13 to rewind onto the winding wheel 12.

[0027] like Figure 5As shown, it also includes a positioning top 15. The two mounting frames 1 are slidably equipped with positioning tops 15 at their lower parts. After the positioning frame 3 is inserted into the soil according to the adjusted spacing, the positioning top 15 is nailed into the ground to better fix the upright frame.

[0028] like Figure 5 As shown, it also includes a connecting rope 16. The upper part of the positioning top 15 is provided with a connecting rope 16. The connecting rope 16 is connected to the lower part of the mounting frame 1. The connecting rope 16 can limit the positioning top 15 on the mounting frame 1 to prevent the positioning top 15 from being lost.

[0029] like Figure 6 As shown, it also includes a bearing seat 17, a connecting rod 18, a telescopic rod 19, a roller 20, and an elastic element 21. The top of one side of the mounting bracket 1 is provided with a bearing seat 17, and the two ends of the bearing seat 17 are symmetrically provided with connecting rods 18. The two connecting rods 18 are each slidably provided with a telescopic rod 19. The roller 20 is rotatably connected between the two telescopic rods 19. One end of the elastic element 21 is connected to the connecting rod 18, and the other end is connected to the telescopic rod 19. The elastic element 21 surrounds the outside of the telescopic rod 19. When the length of the straightening frame is not enough, the two can be connected together. Pull the telescopic rod 19 to the left. At this time, the elastic element 21 is in a contracted state. Then, place the mounting brackets 1 of the two straightening frames together, and then release the telescopic rod 19. At this time, the elastic element 21 starts to recover from the contracted state, giving the telescopic rod 19 a force to the right, driving the telescopic rod 19 and the roller 20 on it to move to the right. Finally, the two straightening frames are fixed. Similarly, multiple straightening frames can be connected together.

[0030] like Figure 6 As shown, both mounting brackets 1 are provided with interlocking slots 22. When connecting two straightening brackets, mounting bracket 1 is inserted into the slot 22 on the other mounting bracket 1, which can lock the mounting brackets 1 together and make the connection more stable.
