Description

Technical Field

[0001] The utility model relates to the technical field of forestry engineering, in particular to a protection device for forestry engineering. Background Art

[0002] As we all know, forest resources are an important part of the global ecosystem and have direct and indirect economic value, such as timber and non-wood forest products. Forest resources also have important environmental benefits, such as air purification, water conservation, soil and water conservation, etc., and play a key role in maintaining ecological balance. Forestry engineering technology includes forest area planning, forest cultivation, forest protection, forest exploitation and other aspects, aiming to improve the quality and quantity of forest resources and achieve efficient utilization and sustainable development.

[0003] After searching, the utility model patent with Chinese patent authorization announcement number CN218072739U discloses a protective device for forestry engineering, which includes two first brackets, the outer surfaces of the two first brackets are hinged, the bottom surfaces of the two first brackets are fixedly connected to two support columns, and two second brackets are arranged below the first brackets. The outer surfaces of the two second brackets are hinged, and the upper surfaces of the two second brackets are fixedly connected to the bottom surfaces of the support columns. It can be positioned at different heights of trees to provide positioning for the clamping and fixing of the fixing mechanism through the coordinated setting of the first bracket, the support column, the second bracket and the fixing mechanism. By utilizing the coordinated action of the first bracket and the second bracket, it can clamp and fix trees of different sizes, and a rubber pad is arranged inside the fixing mechanism to avoid direct fixation causing the trees to be unable to grow, thereby improving the survival rate of the trees.

[0004] Although the above technical solution solves the problem of trees being unable to survive due to being fixed, in the above technical solution, the brackets that constitute the tree protection device increase the complexity of installation and disassembly for workers, reduce work efficiency, greatly increase working time when facing large tracts of forest, and transport the device is time-consuming and labor-intensive. In order to solve the above problems, a protection device for forestry engineering is needed. Utility Model Content

[0059] Working principle:

[0060] When the forestry engineering protection device is used, the forestry engineering protection device is first placed on the tree to be fixed. The operator first places the limit plate 8 against the tree to be protected, and rotates the handle 25 by hand. The rotation of the handle 25 drives the baffle 24 to rotate. The rotation of the baffle 24 drives the wire shaft 22 to rotate. The rotation of the wire shaft 22 drives the first ratchet 16 to rotate. The long wire 23 on the wire shaft 22 can move the long tread plate by rotating, and the long nail 27 is nailed into the ground. The rotation of the first ratchet 16 drives the rotating threaded shaft 5 to rotate. The movable threaded sleeve 6 moves forward and backward by rotating the threaded shaft 5, and the long plate 7 on the rotating threaded sleeve 6 moves together. The first connecting rod 10 on the rotating block 9 moves under the restriction of the rotating block 9, and the second connecting rod 11 moves under the restriction of the first connecting rod 10 and the long plate 7. The third connecting rod 12 restricts the movement of the fourth connecting rod 13. When the rotating threaded sleeve 6 moves forward and backward, the fourth connecting rod 13 will clamp and loosen the tree. When the tree shakes, the first ratchet 16 clamps tighter and tighter under the restriction of the ratchet limit block 20, thereby achieving the effect of stabilizing the tree.
