Abstract
The invention discloses a crawler-type hydraulically-driven tree climbing and pruning robot. The crawler-type hydraulically-driven tree climbing and pruning robot comprises a rack, a holding clampingmechanism, a tree climbing mechanism, a cutting mechanism, an obstacle avoidance mechanism and a handheld mechanism; the rack comprises an upper stand column, a lower stand column, a first connectingrib plate, a second connecting rib plate, a third connecting rib plate, a fourth connecting rib plate and a fifth connecting rib plate, and the holding clamping mechanism comprises a first push rod air cylinder upper connecting plate, a first push rod air cylinder lower connecting plate, a first push rod air cylinder, a clamping wheel upper connecting plate, a clamping wheel lower connecting plate, a clamping plate connecting shaft, a clamping fixing plate, a clamping wheel connecting shaft and a clamping wheel; and the tree climbing mechanism comprises a left crawler assembly, a right crawlerassembly and a right-angle reverser, the cutting mechanism comprises five cutting tool bits, and the obstacle avoidance mechanism comprises a second push rod air cylinder and an air cylinder connecting frame. The technology is high in automation degree, the working efficiency of forestry production is improved, the labor intensity of workers is reduced, and the safety of forestry operation is improved.
Description
technical field [0001] The invention relates to the technical field of forestry engineering equipment, in particular to a crawler-type hydraulically driven standing tree pruning machine. Background technique [0002] According to the latest statistics from the National Forestry and Grassland Administration, as of 2019, my country's artificial forest area has reached 1,390,491 hectares, accounting for 1 / 3 of the world's planted forest area, and has become the country with the largest planted forest area in the world. The area of planted forests continues to increase. [0003] Although my country has achieved a leading position in the world in plantation cultivation, due to our limited management, the growth rate per unit time and unit area of our plantation forests is not high, and most forest areas have not followed the plantation regulations. The directional cultivation of cultivation standards has seriously affected the survival rate and timber quality of our plantation...
