technical field

The invention relates to a bamboo and wood felling device, in particular to a moso bamboo combined harvester.

Background technique

Moso bamboo is the bamboo species that has been cultivated for a long time in China, with the widest area and the most important economic value. Harvesting of moso bamboo includes tending felling of moso bamboo before maturity and main cutting of mature bamboo and overripe bamboo. However, the current logging is mainly semi-mechanized, and the logging methods mainly include traditional sawing, ax cutting, chain sawing, electric sawing, etc. An integrated combined harvesting machine has not yet occurred. With the increasing demand for bamboo and the strong seasonality of moso bamboo, relying on traditional manual logging is not only labor-intensive but also low in labor productivity. It is true that it can no longer meet the needs of modern bamboo production and must be mechanized. to improve production efficiency.

At present, combined harvesters are generally used in large-scale felling. Combined harvesters generally use engineering vehicles with strong off-road capabilities as carriers, and additional working heads are installed on them to harvest trees. The existing working head generally includes a connecting frame, which is connected with the engineering vehicle. A bracket is installed on the connecting frame for rotation. The bracket and the connecting frame are generally driven by an overturning cylinder to make the relative rotation between the two. The bracket is provided with a clip. The holding arm, the clamping arm is driven by the clamping oil cylinder to realize the tightening of the tree, the bracket or the clamping arm is provided with a driving wheel, and a rotatable chainsaw combination is provided on one side of the bracket, and the chainsaw combination is driven by the chainsaw cylinder. . When starting to work, the bracket is in a vertical state under the action of the turning cylinder, and the clamping arm is also in an open state. Adjust the position of the bracket so that the trees to be felled are in the clamping arm, and then close the clamping arm to close the tree. Enclosed in the clamping arm, the chain saw is driven by the chain saw oil cylinder to move towards the clamped tree to cut the tree. When the tree is cut off, the turning cylinder is turned over, so that the support moves along the direction of the tree to a basic level, and then the driving wheel rotates to drive the tree to move along the length of the support. Execution is performed so that only the trunk of the tree remains.

Although this combined harvester is faster than manual harvesting, due to the fewer and slender branches of Moso bamboo, the harvesting speed may be further improved.
