Description

Technical Field

[0001] This utility model relates to the field of scallion anti-lodging technology, and in particular to an adjustable height scallion anti-lodging device. Background Technology

[0002] Scallions are a specialized variety used for producing fresh scallions. As an important vegetable crop suitable for both fresh consumption and processing, they are grown in all scallion-producing areas and offer considerable economic benefits. Upright growth is a crucial quality requirement for scallions; they are typically harvested at around 80cm. However, due to their crispness, tenderness, and high white-to-green ratio, preventing lodging during growth is a key concern for farmers. Lodging causes the plant base to bend, leaves to turn yellow, and overlapping leaves to lead to poor ventilation and light penetration, as well as increased susceptibility to pests and diseases, ultimately rendering the plant unmarketable.

[0003] Currently, trellises are used to ensure that scallion plants stand upright and do not fall over during their growth. The trellises are erected once after the scallion seedlings are planted and will not be removed until harvest. As the plants grow taller, the height of the trellises needs to be adjusted. Before setting up the trellises, stakes need to be driven in manually. In practice, the stakes are usually bamboo poles or thin iron rods. The trellises are directly tied to the bamboo poles or thin iron rods. Because the trellises need to be kept taut, loosening the trellis ropes when adjusting the height will cause the surface of the trellises to loosen, making it very difficult to tighten the trellises again. This makes the overall lifting process of the trellises cumbersome.

[0004] To address this issue, an adjustable-height device for preventing scallions from falling over is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable height scallion anti-loosening device to solve the problems existing in the prior art, facilitate the adjustment of the grid height, and prevent the grid from loosening during the adjustment process.

[0006] To achieve the above objectives, this utility model provides the following solution: This utility model provides an adjustable-height anti-tipping device for scallions, comprising:

[0007] A fixed rod is provided, with a pedal fixedly connected to its bottom end. An insertion rod is fixedly connected to the bottom surface of the pedal. The insertion rod is coaxially arranged with the fixed rod. An upper baffle and a lower baffle are fixedly connected to the fixed rod, with the upper baffle located above the lower baffle. A height adjustment mechanism is provided on the fixed rod, with a connecting ring fixedly connected to the height adjustment mechanism. The connecting ring is used to install the grid. An auxiliary fixing mechanism is also provided on the fixed rod.

[0008] Preferably, the height adjustment mechanism includes a sleeve, which is sleeved on the fixed rod, and a connecting ring is fixedly connected to the sleeve. The sleeve is located between the upper baffle and the lower baffle. A connecting pipe is fixedly connected to the sleeve. A first through hole is opened on the sleeve, which communicates with the connecting pipe. A thread is opened on the inner edge of the connecting pipe, and a screw is threadedly connected to the connecting pipe. The screw has a pointed conical end.

[0009] Preferably, a knob is fixedly connected to the screw.

[0010] Preferably, the auxiliary fixing mechanism includes a first connecting plate, which is fixedly connected to the fixing rod and located below the lower baffle. A second connecting plate is rotatably connected to the first connecting plate, and a positioning plate is fixedly connected to the end of the second connecting plate away from the first connecting plate. A second through hole is provided on the positioning plate, and a positioning rod is inserted into the second through hole.

[0011] Preferably, both the first connecting plate and the second connecting plate are provided with connecting holes, and a rotating shaft is inserted through the connecting holes and rotatably connected to the connecting holes.

[0012] The present invention discloses the following technical effects: In this device, the insertion rod is used to insert into the soil. When inserting, the foot can step on the pedal to make the insertion rod easier to enter the soil. The grid is fixedly connected to the connecting ring. The height adjustment mechanism can adjust the height on the fixed rod, thereby adjusting the height of the connecting ring. The auxiliary fixing mechanism can make the fixed rod more stable.

[0013] This device can be used in multiple ways simultaneously. Four of these devices are used, with the four corners of the grid fixed to the four connecting rings. The grid is located on the top of the scallion. During the growth process, the scallion will pass through the grid, and the support will not be insufficient due to the elongation of the leaves. When there is wind or other external force, the scallion will sway inside the mesh, thus preventing the scallion from falling over.

[0014] This invention not only makes it easy to adjust the height of the grid, but also eliminates the need to loosen the grid during the adjustment process, making it more convenient to use. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1

[0025] Reference Figure 1-3 This utility model provides an adjustable height scallion anti-tipping device, comprising:

[0026] A fixed rod 1 is fixedly connected to a pedal 2 at its bottom end. An insertion rod 3 is fixedly connected to the bottom surface of the pedal 2. The insertion rod 3 is coaxially arranged with the fixed rod 1. An upper baffle 4 and a lower baffle 5 are fixedly connected to the fixed rod 1. The upper baffle 4 is located above the lower baffle 5. A height adjustment mechanism is provided on the fixed rod 1. A connecting ring 6 is fixedly connected to the height adjustment mechanism. The connecting ring 6 is used to install the grid 7. An auxiliary fixing mechanism is provided on the fixed rod 1.

[0027] In this device, the insertion rod 3 is used to insert into the soil. When inserting, the foot can step on the pedal 2 to make it easier for the insertion rod 3 to enter the soil. The grid 7 is fixedly connected to the connecting ring 6. The height adjustment mechanism can adjust the height on the fixed rod 1, thereby adjusting the height of the connecting ring 6. The auxiliary fixing mechanism can make the fixed rod 1 more stable.

[0028] Multiple units of this device are used simultaneously. In this embodiment, four units are used, with the four corners of the grid 7 fixed to four connecting rings 6. The grid 7 is located on the upper part of the scallion. During growth, the scallion will pass through the grid, and the support will not be insufficient due to leaf elongation. Furthermore, when there is wind or other external force, the scallion will sway within the mesh, thus preventing it from falling over. In this embodiment, the grid material 7 is of high hardness, tensile strength, and is not easily deformed, with a mesh side length of 8-10cm.

[0029] The scheme is further optimized. The height adjustment mechanism includes a sleeve 8, which is sleeved on the fixed rod 1. A connecting ring 6 is fixedly connected to the sleeve 8. The sleeve 8 is located between the upper baffle 4 and the lower baffle 5. A connecting pipe 9 is fixedly connected to the sleeve 8. A first through hole is opened on the sleeve 8, which communicates with the connecting pipe 9. A thread is opened on the inner edge of the connecting pipe 9. A screw 10 is threadedly connected to the connecting pipe 9. The screw 10 has a pointed conical end.

[0030] When it is necessary to fix the position of the sleeve 8, rotate the screw 10 so that the tip of the screw 10 abuts against the fixing rod 1, so that the sleeve 8 will not slide on the fixing rod 1. When it is necessary to adjust the position of the sleeve 8, loosen the screw 10, adjust the sleeve 8 to the appropriate position, and then tighten the screw 10.

[0031] The design was further optimized by attaching a knob 11 to the screw 10.

[0032] Knob 11 makes it easy to turn screw 10.

[0033] The scheme is further optimized. The auxiliary fixing mechanism includes a first connecting plate 12, which is fixedly connected to the fixing rod 1. The first connecting plate 12 is located below the lower baffle 5. The first connecting plate 12 is rotatably connected to a second connecting plate 13. The end of the second connecting plate 13 away from the first connecting plate 12 is fixedly connected to a positioning plate 14. A second through hole is opened on the positioning plate 14, and a positioning rod 15 is inserted into the second through hole.

[0034] After inserting the insertion rod 3 into the soil, place the positioning plate 14 on the ground, and then insert the positioning rod 15 into the second through hole and the soil to make the fixing rod 1 more stable.

[0035] In a further optimized design, both the first connecting plate 12 and the second connecting plate 13 have connecting holes, and a rotating shaft 16 passes through the connecting holes, with the rotating shaft 16 rotatably connected within the connecting holes.

[0036] The rotational connection between the first connecting plate 12 and the second connecting plate 13 is achieved through the rotating shaft 16.

[0037] This device is used in multiple applications simultaneously. In this embodiment, four devices are used, with the four corners of the grid 7 fixed to the four connecting rings 6. The grid 7 is located on the upper part of the scallion. During growth, the scallion will pass through the grid, preventing insufficient support due to leaf elongation. Furthermore, when there is wind or other external force, the scallion will sway within the mesh, thus preventing it from falling over. When the position of the sleeve 8 needs to be adjusted, simply loosen the screw 10, adjust the sleeve 8 to the appropriate position, and then tighten the screw 10. Since the grid 7 is connected to the connecting rings 6, adjusting the height of the grid 7 does not require detaching it from the connecting rings 6.

[0038] Example 2

[0039] Reference Figure 4-5 The difference between this embodiment and embodiment 1 is that: the upper baffle 4, the fixing rod 1, the lower baffle 5, the pedal 2, and the insertion rod 3 are all provided with a third through hole, and a push-pull rod 17 is provided in the third through hole. An installation cavity 18 is provided in the insertion rod 3. Two levers 19 are rotatably connected in the installation cavity 18. The levers 19 are rotatably connected in the installation cavity 18 through a rotating shaft. The two levers 19 are symmetrically arranged on both sides of the push-pull rod 17. The levers 19 are L-shaped and are rotatably connected to the push-pull rod 17. The push-pull rod 17 extends out of the third through hole. A lifting plate 20 is fixedly connected to the push-pull rod 17. After the fixing rod 1 is fixed, the lifting plate 20 is pulled up. The lifting plate 20 drives the push-pull rod 17 to move upward. The upward movement of the push-pull rod 17 will drive the lever 19 to rotate, so that one end of the lever 19 extends out of the installation cavity 18 and enters the soil. This can prevent external force from pulling the insertion rod 3 out of the soil and increase stability.
