[0002] At present, when the feed rollers of logging devices on the market are clamping the trunk, the left and right feed rollers move in a relative circular arc, and the left and right feed rollers form a linearly changing angle, which affects the clamping force and grip on the trunk. The position is changing and not ideal, resulting in large feed friction of the trunk and serious damage to the trunk when it is clamped. In addition, for large-diameter trunks, the clamping force of the left and right feed rollers pushes the trunk outward, so The logging device needs a pair of main grippers and a pair of main branching cutters distributed in front of and behind the feed roller to hug the tree trunk. This type of logging device has a complex structure and high cost

Provided is a copying clamping mechanism of a feeding roller of a felling device. The mechanism comprises a main frame of the felling device, a left rocking bar, a left feeding roller mounting rack, aleft curved cam belonging to the left feeding roller mounting rack, a right feeding roller, a synchronous connecting rod, a drive oil cylinder, a right rocking rod, a right feeding roller mounting rack, a right curved cam belonging to the right feeding roller mounting rack, a right feeding roller, a driven idler wheel and a tree trunk. According to the copying clamping mechanism of the feeding roller of the felling device, the cooperative movement of a four connecting rod mechanism and a cam mechanism to make movements is tactfully adopted, the copying clamping problem due to tree trunk diameter changes is solved in the feeding process of the felling device, the feeding friction is reduced, a pair of main lopping cutters can be reduced, and the energy conservation, efficiency, reliabilityand cost reducing of the felling device are achieved.
Description
technical field [0001] The invention relates to a feeding roller profiling clamping mechanism of a felling device, which is used for felling trees in forest farms. Background technique [0002] At present, when the feed rollers of logging devices on the market are clamping the trunk, the left and right feed rollers move in a relative circular arc, and the left and right feed rollers form a linearly changing included angle. The position is changing and not ideal, resulting in a large feed friction force of the trunk, and serious damage to the trunk when it is clamped. In addition, for large diameter trunks, the clamping force of the left and right feed rollers pushes the trunk outward, so The felling device requires a pair of main clamps and a pair of main branching cutters to be distributed before and after the feed roller to hug the tree trunk. This type of felling device has a complex structure and high cost. Contents of the invention [0003] The problem to be solved b...
