Description

TECHNICAL FIELD

[0001] The utility model belongs to seedling correction technical field, concretely relates to a seedling correction device for forestry engineering. BACKGROUND

[0002] In the process of seedling cultivation in forestry engineering, the problem of seedling skew seriously affects the yield and ecological benefits. The artificial binding correction method in the existing correction means is difficult to ensure the stable support of the seedling. With the growth of seedling and environmental changes, the binding structure is easy to loosen, which cannot provide effective support for the seedling continuously, resulting in poor correction effect.

[0003] Part of the simple mechanical support device, its structure design is single, cannot be flexible to adapt to different height, thickness and skew degree of seedling. These devices usually adopt fixed support mode, in actual application, it is difficult to adjust the supporting degree and angle according to the specific growth condition of seedling, not only the correction efficiency is low, and long time use is easy to appear looseness, damage and other problems, cannot provide stable correction effect for seedling. For example, for the seedling variety with shallow root system and thin stem, the conventional mechanical support device cannot accurately apply force, which may cause secondary damage to the seedling in the correction process.

[0004] In addition, the existing seedling correction device has defects in structural stability. The support structure of most devices lacks effective reinforcement and linkage design, and it is difficult to form a stable support system when correcting the seedling. Once disturbed by external force, such as wind and rain, the whole correction device is easy to lose balance, affecting the correction effect, and even damaging the device and the seedling. SUMMARY

[0005] In view of the above problems, the purpose of the utility model is to provide a seedling correction device for forestry engineering, which solves the problems of unstable support, poor adaptability and unstable structure of the existing seedling correction method.

[0006] To achieve the above purpose, the utility model adopts the technical scheme: a seedling correction device for forestry engineering, comprising three connecting plates and three positioning frames, the two ends of the connecting plate are sleeved on the outer side of the positioning frame, the positioning frame comprises a positioning rod, the bottom end of the positioning rod is connected with a spiral rod, one end of the positioning rod is connected with a support frame, the support frame comprises a pipe clamp one and a pipe clamp two, the pipe clamp one and the pipe clamp two are locked on the positioning rod, a connecting seat is installed on the pipe clamp one and the pipe clamp two, one end of a connecting rod is rotatably connected with the two connecting seats through a pin shaft respectively, the other end of the connecting rod is rotatably connected with a connecting frame through a pin shaft, a correction frame is installed on the connecting frame, the correction frame comprises a screw rod, the screw rod is threadedly connected with the connecting frame and rotatably clamped with a top plate.

[0007] The beneficial effects of this utility model are as follows: the three connecting plates can be flexibly inserted around the seedlings and locked by limiting the position through the connecting plates, ensuring the overall stability of the device in supporting the seedlings; the support frame can cooperate with the positioning frame to form a triangular structure to provide stable support for the straightening frame, so that the straightening frame can be adjusted to a suitable length to straighten the seedlings.

[0008] To ensure the stability of the positioning frame installation;

[0009] As a further improvement to the above technical solution: a positioning plate is installed at the bottom end of the positioning rod, and the axes of the positioning rod and the screw rod are collinear.

[0010] The beneficial effects of this improvement are as follows: after the auger rotates and drills into the soil to position the positioning frame, the positioning plate acts as a limit, preventing the positioning frame from sinking further and affecting its support effect on the support frame and the correction frame.

[0011] In order to effectively improve the support stability of the positioning frame for the correction frame by using a support frame;

[0012] As a further improvement to the above technical solution: the two connecting rods, the positioning rod, and the connecting frame form a trapezoidal frame structure.

[0013] The beneficial effects of this improvement are: compared with directly providing support for the straightening frame, the trapezoidal frame structure increases the stress range of the positioning frame, enabling the positioning frame to provide more stable support for the straightening frame.

[0014] To effectively connect and reinforce multiple positioning frames using connecting plates;

[0015] As a further improvement to the above technical solution: the two ends of the connecting plate are fitted onto the outside of the two positioning rods, and the three connecting plates form a triangular frame structure.

[0016] The beneficial effects of this improvement are: the three connecting plates can stably connect the three positioning frames into a whole, thereby further strengthening the positioning frames and improving the support stability of the positioning frames.

[0017] To improve the supporting stability of the roof slab;

[0018] As a further improvement to the above technical solution: the top plate is connected to one end of the guide rod, the guide rod is slidably inserted into the connecting frame, and the axis of the guide rod is parallel to the axis of the screw.

[0019] The beneficial effects of this improvement are: the guide rod plays a limiting and guiding role, enabling the top plate to move stably under the drive of the screw.

[0020] To ensure the screw drives the top plate to move stably;

[0021] As a further improvement to the above technical solution: limiting plates are fixed on the screws on both sides of the top plate.

[0022] The beneficial effects of this improvement are: the limiting plate plays a limiting role, enabling the screw to move synchronously with the top plate when it moves relative to the connecting frame.

[0023] To reduce effort, the drive screw rotates;

[0024] As a further improvement to the above technical solution: a hexagonal prism is fixed at one end of the screw.

[0025] The beneficial effect of this improvement is that operators can use a wrench or other tools to connect the hexagonal prism and thus turn the screw with less effort.

[0026] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0032] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0033] Example 1:

[0034] like Figure 1As shown in Figure 4: A seedling straightening device for forestry engineering includes three connecting plates 1 and three positioning frames 2. The two ends of the connecting plates 1 are fitted onto the outside of the positioning frames 2. Each positioning frame 2 includes a positioning rod 21, with a spiral rod 22 connected to the bottom end of the positioning rod 21. The positioning rod 21 is connected to one end of a support frame 3. The support frame 3 includes a first pipe clamp 31 and a second pipe clamp 32, which are locked onto the positioning rod 21. Each of the first pipe clamp 31 and the second pipe clamp 32 is equipped with a connecting seat 33. Two connecting seats 33 are rotatably connected to one end of a connecting rod 34 via pins. The other end of the connecting rod 34 is rotatably connected to the pin. A connecting frame 35 is connected, on which a straightening frame 4 is installed. The straightening frame 4 includes a screw 41, which is threaded to the connecting frame 35 and rotatably engages with the top plate 43. Three connecting plates 1 can be flexibly inserted around the seedling and are locked in place by the connecting plates 1 to ensure the overall stability of the device in supporting the seedling. The support frame 3 can cooperate with the positioning frame 2 to form a triangular structure to provide stable support for the straightening frame 4, allowing the straightening frame 4 to be adjusted to a suitable length to straighten the seedling. A positioning plate 23 is installed at the bottom of the positioning rod 21. The axes of the positioning rod 21 and the spiral rod 22 are collinear. The spiral rod 22 rotates and drills into the soil to achieve the positioning of the positioning frame 2. The positioning plate 23 serves as a limit, preventing the positioning frame 2 from sinking further and affecting its support effect on the support frame 3 and the straightening frame 4. The two connecting rods 34, the positioning rod 21, and the connecting frame 35 form a trapezoidal frame structure. Compared to directly providing support for the straightening frame 4, the trapezoidal frame structure increases the stress range of the positioning frame 2, allowing it to more stably support the straightening frame 4. The two ends of the connecting plate 1 are fitted onto the outside of the two positioning rods 21. The three connecting plates 1 form a triangular frame structure, which can stably connect the three positioning frames 2 into a whole, thereby further strengthening the positioning frame 2. To improve the support stability of the positioning frame 2, the top plate 43 is connected to one end of the guide rod 45, and the guide rod 45 is slidably inserted into the connecting frame 35. The axis of the guide rod 45 is parallel to the axis of the screw 41. The guide rod 45 plays a limiting and guiding role, so that the top plate 43 can move stably under the drive of the screw 41. Limiting plates 44 are fixed on the screws 41 on both sides of the top plate 43. The limiting plates 44 play a limiting role, so that when the screws 41 move relative to the connecting frame 35, they can drive the top plate 43 to move stably and synchronously. A hexagonal prism 42 is fixed to one end of the screw 41. The operator can use a wrench or other tools to connect the hexagonal prism 42 to rotate the screw 41 with less effort.

[0035] The working principle of this technical solution is as follows: When using this forestry engineering seedling straightening device, firstly, according to the size and tilt of the seedling, select a suitable installation position, and place the three positioning frames 2 in a triangular arrangement around the seedling, so that the spiral rod 22 of the positioning frame 2 is aligned with the ground. The operator holds the positioning rod 21 and rotates the positioning rod 21 with a pipe wrench to drive the spiral rod 22 to rotate, so that the spiral rod 22 gradually penetrates into the soil. When the spiral rod 22 penetrates to a suitable depth, the positioning plate 23 contacts the ground, which plays a limiting role and prevents the positioning frame 2 from sinking further, thereby completing the stable installation of the positioning frame 2 and providing a stable foundation support for subsequent straightening work.

[0036] Next, the two ends of the three connecting plates 1 are respectively fitted onto the outside of the corresponding positioning rods 21. Since the three connecting plates 1 form a triangular frame structure, the three positioning frames 2 can be stably connected into a whole, which further enhances the support stability of the positioning frames 2, so that the entire correction device remains stable in subsequent work and will not easily shake or shift.

[0037] Then, install the support frame 3, and lock the pipe clamp 31 and the pipe clamp 32 at appropriate positions on the positioning rod 21. By adjusting the height of the pipe clamp 31 and the pipe clamp 32 on the positioning rod 21, the angle and position of the support frame 3 can be changed to accommodate seedlings of different heights and degrees of tilt. Since the two connecting rods 34, the positioning rod 21, and the connecting frame 35 form a trapezoidal frame structure, the force-bearing range of the positioning frame 2 is increased. Compared with the positioning frame 2 directly supporting the correction frame 4, it can provide more stable support for the correction frame 4.

[0038] Finally, the seedlings are straightened. The operator uses a wrench or other tools to put on the hexagonal prism 42 at one end of the screw 41. By rotating the screw 41, the top plate 43 is moved. The position of the top plate 43 is adjusted according to the direction and degree of the seedling's tilt, so that the top plate 43 contacts the seedling trunk and applies appropriate corrective force. The seedling is safely and gradually straightened to an upright state in multiple steps over a longer period of time.
