The working principle is as follows: moving the device to enable the tree to be located inside the felling channel 11, turning on a switch of a motor in the driving device 5, driving a driving wheel 31 to rotate by the motor through a driving shaft 311, driving a felling chain belt 32 to rotate by the driving wheel 31, cutting the tree by a cutting block on the felling chain belt 32, pushing the device in the cutting process to enable the tree to move towards the tip of the left end of the felling channel 11, and enabling the felling chain belt 32 to achieve the cutting effect on the tree as the distance between the tree and the felling chain belt 32 is smaller and smaller; in the rotating process of the felling chain belt 32, the inner concave part of the felling chain belt will be continuously contacted with the movable impact block 62, and the movable impact block 62 will make the felling chain belt 32 vibrate through the inner concave part of the felling chain belt 32, so that the sawdust on the felling chain belt 32 falls off;

when the tree moves to contact with the blocking and pushing-off plate 42, the tree pushes the central rotating shaft 41 to rotate through the blocking and pushing-off plate 42, the central rotating shaft 41 drives the pushing block 411 to rotate, the contact between the arc-shaped protrusion of the pushing block 411 and the movable impact block 62 pushes the movable impact block 62 to move, under the elastic action of the felling chain belt 32, the movable impact block 62 is reset after being separated from the arc-shaped bulge of the pushing block 411, so as to realize the reciprocating motion of the movable impact block 62 and the swinging effect of the felling chain belt 32, thereby promoting the falling off of the wood chips on the felling chain belt 32, and simultaneously, the cylindrical protrusion of the central rotating shaft 41 can slide among a plurality of longitudinal grooves on the surface of the trees so as to realize the short-distance reciprocating motion process in the integral rotating process of the central rotating shaft 41, so that the pushing block 411 also generates corresponding short-distance reciprocating motion to improve the pushing effect of the pushing block 411 on the movable impact block 62; when the driving elastic sheet 4131 rotates to the straight surface of the driving plate 81, the driving elastic sheet 4131 is pushed by the driving plate 81 to deform, so that a certain reverse reset force is given to the central rotating shaft 41 and the blocking push-off plate 42, the reset force can generate a pushing effect towards the left side far away from the felling device 1 on the position where the tree is higher, meanwhile, the reinforcing push-off plate 412 can play a pushing effect towards the left side near the felling device 1 on the position where the tree is lower under the action of the elastic piece, and when the tree is completely cut off, the clockwise rotation state of the tree can be realized when two different directions of force are applied to different positions of the tree, so that the tree falls down towards the left side far away from the felling device 1, and the operator is prevented from being injured by falling down of the tree;

the saw-dust that drops on the felling chain belt 32 can strike on mounting panel 8 and stop at triangle guide plate 7 top, can promote the drive plate 81 through the arcwall face at drive plate 81 top before drive shell fragment 4131 and the flat face contact of drive plate 81 descends, drive plate 81 descends in-process can make triangle guide plate 7 rotate, and triangle guide plate 7 left end highly can rotate to being less than the right-hand member height, triangle guide plate 7 rotates the in-process and can produce the collision with slope piece 9, this collision can make saw-dust on the triangle guide plate 7 remove until stopping at slope piece 9 top to slope piece 9, under the guide effect of slope piece 9, the saw-dust can slowly shift out felling device 1 from discharge channel 12, prevent that the saw-dust from splashing and leading to operating personnel injured.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
