Description

Technical Field

[0001] This utility model relates to a tree pruning machine for forest land, belonging to the technical field of tree pruning machines. Background Technology

[0002] Fast-growing forests are plantations with short rotation cycles, and are in high demand in the industrial paper industry. Due to their rapid growth, good quality, and high survival rate, they have significant economic value. The planting area of ​​fast-growing forests in my country is continuously expanding. However, the management methods for these forests are outdated, particularly regarding pruning. Proper pruning can promote tree growth, improve straightness, roundness, bending strength, and wood toughness, improve the forest's growth environment and fire resistance, and enhance photosynthesis in the upper parts of the forest. Currently, many regions in my country suffer from improper pruning methods or even neglect of pruning. The main reason for this is the relatively outdated pruning machinery used in forest areas, which suffers from poor safety, high labor intensity, low pruning efficiency, poor pruning quality, and failure to meet pruning height requirements.

[0003] Existing technologies include forest pruning machines, such as the pruning and brush trimming machine disclosed in application number 202321244200.2, which includes a collection box. A blower is fixedly connected to one side of the inside of the collection box. One end of the blower is connected to a guide pipe, and one end of the guide pipe is connected to a dust removal plate. A filter plate is fixedly installed inside the dust removal plate. A clamping plate is fixedly connected to the top of the collection box, and a fixing plate is fixedly connected to one side of the top of the collection box. This pruning and brush trimming machine, through the arrangement of the blower, guide pipe, and dust removal plate, and because the bottom of the collection box is fixedly installed with rotating wheels, pushes the handle on one side of the collection box to move the device to a suitable position, so that the dust removal plate can contact the area that needs dust removal. When the blower is turned on, fallen leaves and other garbage are sucked into the inside of the collection box through the guide pipe by the dust removal plate, which is conducive to dust removal and facilitates the centralized treatment of garbage, thereby achieving the effect of protecting the environment.

[0004] Based on existing technologies, the machine can automatically prune branches and collect the pruned debris. However, the pruning structure is raised and lowered during use, which leads to low accuracy, easy jamming, complex structure, and high cost due to the pruning angle, stability, and lack of visual operation. Therefore, a forest pruning machine is needed to improve upon these shortcomings. Utility Model Content
