13 bearing pins 27 and the 14th bearing pin 31.
Operation principle and process：
As shown in Figure 3 and Figure 4, when mechanism is ten connecting rod single-degree-of-freedom, the 3rd bearing pin 4 and the 5th bearing pin 9 are in overlapping bit
Put, rear rocking bar 10, back link 6 and middle rocking bar 11 can regard lanar four rod mechanism as, stock 5 and middle connecting rod 2 pass through the 5th pin
Axle 9 is connected, and middle connecting rod 2 and output connecting rod 19 are connected by the first bearing pin 1, and output connecting rod 19 and stock 5 pass through the 12nd bearing pin
22 connections, therefore stock 5, middle connecting rod 2 and output connecting rod 19 can regard a bar as, preceding rocking bar 29 is around 18 turns of the 9th bearing pin
It is dynamic, because front rod 28 and preceding rocking bar 29 are connected by the 13rd bearing pin 27, and then drive front rod 28 to rotate, the He of cradling piece 16
Front rod 28 is connected by the 11st bearing pin 21, and then drives cradling piece 16 to be rotated around the 8th bearing pin 17, stock 5 and cradling piece
16 are connected by the tenth bearing pin 20, and then output connecting rod 19 is made single dof mobility.
As shown in Figure 5 and Figure 6, when mechanism is that ten connecting rod two-freedoms are moved, preceding rocking bar 29 is rotated around the 9th bearing pin 18,
Because front rod 28 and preceding rocking bar 29 are connected by the 13rd bearing pin 27, and then front rod 28 is driven to rotate, cradling piece 16 is with before
Connecting rod 28 is connected by the 11st bearing pin 21, and then drives cradling piece 16 to be rotated around the 8th bearing pin 17, and middle rocking bar 11 is around the
Seven bearing pins 13 are rotated, and because middle connecting rod 2 and middle rocking bar 11 are connected by the 5th bearing pin 9, the two ends of tripod 7 connect with middle connecting rod 2
Connect, tripod 7 and middle connecting rod 2 can now be regarded as to connecting rod 2 in a bar, and then drive and rotated, rear rocking bar 10 is around the 6th
Bearing pin 12 is rotated, because back link 6 and rear rocking bar 10 are connected by the 4th bearing pin 8, and then drives back link 6 to rotate, the He of stock 5
Back link 6 is connected by the 3rd bearing pin 4, and the middle part of stock 5 and cradling piece 16 are connected by the tenth bearing pin 20, and then makes stock 5 real
Existing plane motion, output connecting rod 19 and middle connecting rod 2 are connected by the first bearing pin 1, and the middle part of output connecting rod 19 and stock 5 pass through the tenth
Two bearing pins 22 are connected, and then output connecting rod 19 is made two-freedom motion.
As shown in Figure 7 and Figure 8, when mechanism is that 11 connecting rod two-freedoms are moved, preceding rocking bar 29 is around 18 turns of the 9th bearing pin
It is dynamic, because front rod 28 and preceding rocking bar 29 are connected by the 13rd bearing pin 27, and then drive front rod 28 to rotate, the He of cradling piece 16
Front rod 28 is connected by the 11st bearing pin 21, so drive cradling piece 16 rotated around the 8th bearing pin 17, middle rocking bar 11 around
7th bearing pin 13 is rotated, because middle connecting rod 2 and middle rocking bar 11 are connected by the 5th bearing pin 9, and then connecting rod 2 is rotated in driving, by
Connected in tripod 7 and middle rocking bar 11 by the 5th bearing pin 9, and then drive tripod 7 to rotate, rear rocking bar 10 is around the 6th bearing pin
12 rotate, because back link 6 and rear rocking bar 10 are connected by the 4th bearing pin 8, and then drive back link 6 to rotate, the He of the second bearing pin 3
3rd bearing pin 4 is in lap position, and now rear rocking bar 10, back link 6, tripod 7 and middle rocking bar 11 constitute the connecting rod machine of plane five
Structure, stock 5 and back link 6 are connected by the 3rd bearing pin 4, and 5 are connected with cradling piece 16 by the tenth bearing pin 20 in stock, and then
Stock 5 is set to realize plane motion, output connecting rod 19 and middle connecting rod 2 are connected by the first bearing pin 1, the middle part of output connecting rod 19 and stock
5 are connected by the 12nd bearing pin 22, and then output connecting rod 19 is made two-freedom motion.
As shown in Figure 3, Figure 4, Figure 11 and Figure 12, by driving hydraulic cylinder 24, hydraulic cylinder 24 is extended, and then drives Hooke
Rotation pair between hinge 26 and felling head combined mechanism 25 is rotated, and realizes the unitary rotation of felling head combined mechanism 25.
As shown in Fig. 1, Fig. 4, Fig. 6 and Fig. 8, when felling head combined mechanism 25 is in vertical state, trees training tree felling machine
Operation is carried out in lower position, can realize that whole trees cut down saw function.
As shown in Fig. 2, Fig. 3, Fig. 5, Fig. 7, Fig. 9 and Figure 10, felling head combined mechanism 25 is in horizontality, trees training
Tree felling machine carries out operation in lower position, can realize that timber is segmented interception function；When being worked in higher position, tree can be realized
The training grooming function of wood.
