Bent seedling correcting device for forestry planting

Abstract

The invention discloses a bent seedling correcting device for forestry planting. The device comprises two fixed plates fixed on the ground; the cross section of each fixed plate is in a right trapezoid shape; threaded holes are formed in the positions, close to the middle, of the outer walls of the tops of the two fixed plates; threaded nails are respectively connected to the inner walls of the two threaded holes in a threaded mode; the outer wall of each threaded nail is welded with thorn hook which are annularly distributed at equal intervals; one side of the outer wall of the bottom of eachfixing plate is provided with first barbs; the other side of the outer wall of the bottom of each fixing plate is provided with second barbs, and the arrangement direction of the first barbs is opposite to the arrangement direction of the second barbs. Through the device provided by the invention can be used to prevent a seedling from damage caused by shaking, wherein the seedling is shaken due to the fact that a device is not firmly fixed under strong wind. The friction force between the fixed plates and the ground can be further improved, the pressure borne by windproof plates can be relieved, the windproof plates can be protected, and ropes can be prevented from slipping off the fixed nails.

Description

technical field [0001] The invention relates to the technical field of forestry planting, in particular to a curved sapling correction device for forestry planting. Background technique [0002] Trees are the most important plants in forestry. Planting saplings can not only improve the air quality, but also improve the soil, which plays an important role in the protection of the soil environment. When planting trees, the saplings are usually cultivated. When growing up, the saplings are transplanted, but when the saplings are being cultivated, due to wind and other reasons, some saplings will bend when they grow, and if the curved saplings cannot be corrected, the trees will eventually grow. become deformed and affect the growth of trees. [0003] After retrieval, the Chinese patent authorization number is CN205830627U, which discloses a sapling correction device, including vertically distributed vertical columns fixed on both sides of the trunk, two clamping shells for wra...

AI Technical Summary

Problems solved by technology

There are the following deficiencies in the above-mentioned patents: 1. When the device is fixed, because the fixation is not firm and affected by the wind, the device may drive the saplings to shake together, causing the saplings to be damaged; 2. When the saplings are corrected, if the strong wind blows directly 3. When the rope is fixed, the rope slips from the device due to too little friction between the rope and the device, which affects the correction of the sapling.
