Description

Technical Field

[0001] The utility model belongs to the technical field of excavating devices, and in particular relates to a device for crushing felled piles and bamboo baskets on site. Background Art

[0002] Bamboo forests are known as the "second forest resource" and are an important forest resource in my country. After felling, the roots of bamboo baskets are buried in the soil. Under natural conditions, it takes 8 to 10 years for them to rot. The unrotten bamboo baskets buried in the soil are as hard as stones, which hinder the penetration and growth of bamboo whips. At the same time, they occupy the space for the growth of other plants, absorb nutrients from the soil, and ineffectively occupy a large area of ​​forest land, which is not conducive to the growth of other new plants and the renewal of bamboo forests. According to surveys, in bamboo forests, bamboo whips occupy about 1 / 10 of the area. Digging out the remaining roots in the soil after felling can not only make use of this part of the forest land, but also the dug bamboo baskets and bamboo roots can be reused as processing raw materials, which can not only nurture bamboo forests but also increase income, which is worth promoting.

[0003] The following are the current methods for removing bamboo baskets:

[0004] Manual digging: dead bamboos are dug out manually with hoes. Due to the high labor cost, no one is willing to do this, and the dead bamboos cannot be dug out in time, so the bamboo forest cannot maintain normal growth.

[0005] Vertical basket splitting: Under natural conditions, the basic tissue of the bamboo basket is destroyed after splitting, which increases the area of ​​the bamboo basket exposed to the air and promotes its natural decay. However, the decay rate is still relatively slow. It is only suitable for bamboo forests that do not require high renewal speed, and the scope of promotion and application is limited.

[0006] Crushing: A tool similar to an electric drill is used, which is equipped with a drill-like tool, driven by electricity, and manually controlled to drill downward to crush the bamboo basket. However, the existing tools cannot be disassembled, which is not conducive to transportation and use.

[0007] Pulling out: Use a tripod, a human winch and a clamp similar to a grab to clamp the upper part of the bamboo basket and pull out the bamboo basket and bamboo roots. The overall structure is large and is not suitable for use on bamboo mountains.

[0008] Chemical corrosion: Chemical corrosion is currently the most commonly used method for cleaning bamboo baskets, but chemical agents will cause pollution to the forest land.

[0009] The above methods all have major drawbacks, mainly low efficiency or chemical agents will cause pollution to the forest land. In view of this situation, we provide a time-saving, labor-saving and efficient power machinery to carry out bamboo basket removal work. Utility Model Content
