Description

Technical Field

[0001] This utility model relates to the field of seedling planting technology, specifically a terrain-adaptive seedling planting frame for plateau afforestation. Background Technology

[0002] When planting seedlings in high-altitude areas, challenges arise such as complex and diverse terrain (e.g., slopes, undulating terrain), limited transportation conditions, and the need for stable support during seedling growth.

[0003] Traditional seedling planting frames are mostly fixed structures, making it impossible to adjust their shape and footprint to suit different terrains on plateaus, which can easily lead to instability. Furthermore, traditional frames are often monolithic, large, and heavy, making them difficult to transport on rugged plateau roads and challenging to install on-site. In addition, the fixed length of the supporting components in traditional frames cannot accommodate seedlings of different heights, and the rigid structures in contact with the seedlings are prone to damaging the trunks during growth. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a terrain-adaptive seedling planting frame for plateau afforestation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a terrain-adaptive seedling planting frame for plateau afforestation, comprising a support frame assembly, the support frame assembly comprising a first threaded connecting cylinder, a first connecting block connected to the upper end of the first threaded connecting cylinder, a first fastening bolt connected to the first connecting block, a support ring connected to the first connecting block via the first fastening bolt, a bidirectional threaded rod connected to the inner side of the first threaded connecting cylinder, a rotating block connected to the middle position of the bidirectional threaded rod, a second threaded connecting cylinder connected to the lower end of the bidirectional threaded rod, a guide limiting slide rod connected to the outer side of the first threaded connecting cylinder, and a second fastening bolt connected to the lower end of the second threaded connecting cylinder.

[0006] As a further description of the above technical solution:

[0007] The lower side of the support frame assembly is provided with a disassembly and assembly unit. The disassembly and assembly unit includes a first connecting frame. One end of the first connecting frame is connected to a first connecting plate. The other end of the first connecting frame is connected to a third connecting frame through a second connecting plate. There are two sets of second connecting plates. The end of the third connecting frame away from the other set of second connecting plates is connected to a fourth connecting frame through a fixing pin. One end of the fourth connecting frame is connected to a second connecting frame through a second connecting plate.

[0008] As a further description of the above technical solution:

[0009] The support frame assembly is provided in three sets, which are evenly distributed on the first connecting plate and the two sets of second connecting plates. The lower end of the second threaded connecting cylinder is connected to the first connecting plate by the second fastening bolt, and the other two sets of second threaded connecting cylinders are connected to the two sets of second connecting plates by the other two sets of second fastening bolts.

[0010] As a further description of the above technical solution:

[0011] The upper and lower ends of the bidirectional threaded rod are respectively threaded to the inner sides of the first threaded connecting cylinder and the second threaded connecting cylinder. The guide limiting slide rod is fixedly set on the outer side of the first threaded connecting cylinder, and the guide limiting slide rod is slidably connected to the ring set on the outer side of the second threaded connecting cylinder.

[0012] As a further description of the above technical solution:

[0013] The first connecting block is disposed at the upper end of the first threaded connecting cylinder, and the first connecting block is connected to an extension plate disposed on one side of the support ring by a first fastening bolt.

[0014] As a further description of the above technical solution:

[0015] The end of the first connecting frame away from the second connecting plate is rotatably connected to the end of the second connecting frame away from another set of second connecting plates via the first connecting plate, and the first connecting frame and the third connecting frame are connected via the second connecting plate, and the second connecting frame and the fourth connecting frame are connected via the second connecting plate.

[0016] As a further description of the above technical solution:

[0017] The third connecting frame has an extension block at the end away from the second connecting plate, and the fourth connecting frame has a U-shaped groove at the end away from the other set of second connecting plates. The extension block slides in the U-shaped groove, and the fixing pin slides through and connects the extension block and the U-shaped groove to connect the third connecting frame and the fourth connecting frame. The first connecting frame, the first connecting plate, the third connecting frame and the fourth connecting frame are combined to form an equilateral triangle.

[0018] This utility model has the following beneficial effects:

[0019] 1. By rotating the connecting frames and connecting plates of the disassembly and assembly unit, and by using pin-type connections between the third and fourth connecting frames, the device can be flexibly assembled and disassembled. This solves the problems of difficult transportation and inconvenient on-site installation of traditional integral frames. At the same time, the angle of the connecting frames can be adjusted to adapt to complex environments such as plateau slopes and undulating terrain, ensuring that the device is placed stably. The triangular support structure formed by the three sets of support frame components, combined with the equilateral triangular frame of the disassembly and assembly unit, greatly improves the overall stability of the device, prevents the device from tipping over under the action of plateau winds, and provides stable support for seedling growth.

[0020] 2. The length can be precisely adjusted by using a two-way threaded rod and a guide limit slide rod, which can be adapted to seedlings of different heights and solve the problem of fixed support length in traditional frames; the support ring is made of elastic metal material, which can not only fit the seedling to provide lateral support, but also adapt to the diameter changes during the growth of the seedling and prevent squeezing damage.
