Special bamboo feller

Abstract

The invention discloses a special bamboo feller, which comprises a circular saw driven by a gasoline engine. The circular saw is arranged on a slide rail, a spring is arranged in the slide rail, a gripper for fixing a bamboo pole is arranged in front of the slide rail, the gripper is connected with a fixed bar through a connecting bar, the slide rail is connected with a chassis through a support,the gripper is connected with the chassis, the fixed bar is connected with the chassis, and an operation locking device is arranged on the fixed bar and the chassis. The special bamboo feller is simple in structure, small in size, light in weight, powerful, high in operating efficiency and convenient in use. When the special bamboo feller is operated, forest bamboo can be firmly fixed by the gripper at the front end and can be upright constantly during felling, so that forest bamboo quality is guaranteed effectively during felling. The circular saw is convenient in detachment and wear-resistant. The whole special bamboo feller is simple, low in required labor cost, high in labor efficiency, highly practical and capable of bringing good economic benefit and social benefit.

Description

technical field [0001] The invention belongs to the technical field of forest and bamboo felling machinery, and in particular relates to a special harvester for bamboo. Background technique [0002] As of 2007, my country's planted forest area has reached 53 million hm2, ranking first in the world. China is the kingdom of bamboo, with an area of ​​more than 7.2 million hectares of bamboo forests 2 , of which the artificially managed bamboo forest covers an area of ​​5 million hm 2 , accounts for 10% of my country's artificial forest area, and bamboo industry, as the top ten sunrise industries of my country's forestry industry, has become a pillar industry for the development of southern hilly and mountainous areas. [0003] With the advancement of science and technology and the implementation of some high-yield cultivation measures for bamboo forests, at present, large-scale extensive management of bamboo forests has become intensive management. After the transformation of...

Problems solved by technology

However, with the prolongation of operating time and the increase of operating intensity, the operating cost has increased rapidly, mainly in the fact that the labor cost required for harvesting bamboo stalks is too high, and the cost of harvesting bamboo forests has become an important factor restricting the development of my country's bamboo industry.

Olov? ? You Nuosen designed a tree felling machine (95197643.5) in 1995. With the advancement of technology, chain saws are also popular in the forestry field as a kind of felling work. These two machines have certain advantages for felling common tree species. Advantages, however, there are certain problems in the harvesting of bamboo: the bamboo stalk is composed of three parts: bamboo green, bamboo yellow, and bamboo cavity. The bamboo cavity is a hollow structure. Problem: The chain saw will pinch the saw blade during the sawing process; the bamboo will tilt to one side during the sawing process, and the unsawed bamboo will be torn from the incision during the bamboo tilting process, thus affecting the quality of the bamboo

In 2008, Liu Jinhao and others designed a forest harvester (200820123306.6), which integrates logging, branching, papermaking, and tip cutting. It has high work efficiency, safety, and saves manpower. Small, however, due to its large size, this harvester is only suitable for small-density forest types, and cannot be used in conventionally managed bamboo forests

[0004] To sum up, so far, there has not been a harvesting machine suitable for bamboo. Therefore, at present, bamboo harvesting in my country is mainly manual felling, and the rate of manual harvesting is relatively slow, and the operating cost is too high. According to the calculation, the cutting efficiency of workers is 50 roots / day, and the annual cost of bamboo felling in my country is 678 million yuan, and with the development of my country's economy, workers' wages continue to rise, and the cost of bamboo felling will also continue to increase. This shows that, The increase in this cost has become one of the main factors restricting the development of my country's bamboo industry, and has also become a stumbling block for my country's bamboo farmers to increase their income.
