Specific embodiment：
Technical scheme of the present invention is further described with reference to the accompanying drawings and examples.
As shown in Fig. 1, Fig. 9 and Figure 12, restructural lumbering delimber of the present invention, concrete structure and connection relation
For：
The lumbering delimber its first side lever 7 in initial structure state is connected by third straight pin 9 with pedestal 8, the first side
Bar 7 is connected with the connection mode of prismatic pair with the first sliding bar 5, and the first circular arc flap 6 is mounted on the first side lever 7, and first slides
Lever 5 is connected by the second straight pin 4 with first connecting rod 3, and chopping disk 1 is connected by the first straight pin 2 with first connecting rod 3, the
One connecting rod 3 is connected by the first straight pin 2 with second connecting rod 10, and second connecting rod 10 passes through the 4th straight pin 11 and the second sliding bar
13 are connected, and the second sliding bar 13 is connect with the connection mode of prismatic pair with the second side lever 14, and the second circular arc flap 12 is mounted on the
On two side levers 14, the second side lever 14 is connected by the 5th straight pin 15 with pedestal 8, and circular arc fixed gear is welded on the first side lever 7
Plate 16 is welded with moving block 17 on first sliding bar 5, and the first side lever 7 has identical structure with the second side lever 14, and first slides
Bar 5 has identical structure with the second sliding bar 13.
As the graph shows, circular arc is welded on first side lever 7 and fixes plate washer 16, for installing the first circular arc flap 6.
As shown in Figure 10,7 elongated slot is provided on first side lever, the first sliding bar 5 can slide in elongated slot.
As shown in figure 12, it is welded with moving block 17 on first sliding bar 5.
The present invention operation principle be：The key of the lumbering delimbing mechanism state transformation is can be between prismatic pair and revolute pair
The peculair motion pair of transformation, the kinematic pair use the connection between the first side lever 7 and the first sliding bar 5,14 He of the second side lever
Connection between second sliding bar 13.Illustrate the peculair motion by taking the connection mode of the first side lever 7 and the first sliding bar 5 as an example
Secondary operation principle, the shift theory of connection mode is also identical between the second side lever 14 and the second sliding bar 13.When first
When sliding bar 5 moves in the elongated slot in the first side lever 7, the connection mode between the first sliding bar 5 and the first side lever 7 is mobile
Pair connection, as shown in Figure 10；When the first sliding bar 5 is moved to the top of the first side lever 7, circular arc fixes plate washer 16 by the first cunning
17 grades of moving block in lever 5 is lived, and the first circular arc flap 6 rotates 180 ° to underface at this time, it is made to encase on the first sliding bar 5
Moving block 17, at this time the connection mode of the first side lever 7 and the first sliding bar 5 connect for revolute pair, as shown in figure 11.When first
Connection mode between 7 and first sliding bar 5 of side lever is connected for prismatic pair, the company between the second side lever 14 and the second sliding bar 13
When connecing mode and connecting for prismatic pair and overlapped without any rod piece, mechanism is in original state, as shown in Figure 1, mechanism at this time
Space and rigidity are all larger, but its local flexibility is poor, is suitble to cut down the trunk of major diameter；When the first side lever
7 connect with the connection mode of the first sliding bar 5 for revolute pair, and the connection mode of the second side lever 14 and the second sliding bar 13 is movement
When pair connection and no any rod piece coincidence, mechanism is in the second structure state, as shown in Fig. 2, the space of mechanism is than just at this time
Beginning structure state it is big, but rigidity is declined, the trees for being suitble to felling diameter moderate；When the first side lever 7 and the first sliding bar 5
Connection mode is revolute pair connection, and the connection mode of the second side lever 14 and the second sliding bar 13 is that revolute pair is connect and not any
When rod piece overlaps, mechanism is in third structure state, as shown in figure 3, the working space of mechanism is maximum at this time, but rigidity is poor, fits
Close the smaller trunk of diameter of felling higher position；When the connection mode of the first side lever 7 and the first sliding bar 5 is connect for revolute pair,
The connection mode of second side lever 14 and the second sliding bar 13 connect for revolute pair and the first side lever 7 and the second side lever 14 and pedestal
During 8 coincidence, mechanism is in the 4th structure state, as shown in figure 4, the rigidity of mechanism and space are all moderate at this time, is suitble to diameter
General branch carries out delimbing；When the connection mode of the first side lever 7 and the first sliding bar 5 is connect for revolute pair, the second side lever 14
It being connect with the connection mode of the second sliding bar 13 for revolute pair, the first side lever 7 and the second side lever 14 are overlapped with pedestal 8, and first
Sliding bar 5 is overlapped with the second sliding bar 13, and when first connecting rod 3 is overlapped with second connecting rod 10, mechanism is in the 5th structure state, such as Fig. 5
Shown, the flexibility of mechanism is most strong at this time, is suitble to carry out delimbing to the branch of medium-small diameter；When the first side lever 7 and first slides
The connection mode of bar 5 is prismatic pair connection, and the connection mode of the second side lever 14 and the second sliding bar 13 is that prismatic pair is connect and the
When one connecting rod 3 is overlapped with second connecting rod 10, mechanism is in the 6th structure state, as shown in fig. 6, the working space of mechanism is moderate at this time,
Local flexibility is stronger, and the trunk moderate to diameter is suitble to be cut down and carries out delimbing to larger-diameter branch；When first
Side lever 7 is connect with the connection mode of the first sliding bar 5 for revolute pair, and the connection mode of the second side lever 14 and the second sliding bar 13 is
When prismatic pair connects and first connecting rod 3 is overlapped with second connecting rod 10, mechanism is in the 7th structure state, as shown in fig. 7, the sky that works at this time
Between it is bigger than the 6th structure state, rigidity is more smaller than the 6th structure state, and local flexibility is strong, be suitble to the small trunk of centering cut down；When first
Side lever 7 is connect with the connection mode of the first sliding bar 5 for revolute pair, and the connection mode of the second side lever 14 and the second sliding bar 13 is
Revolute pair connects and first connecting rod 3 with second connecting rod 10 when overlapping, mechanism is in the 8th structure state, as shown in figure 8, mechanism at this time
Working space is larger, and rigidity is moderate, is suitble to carry out delimbing to the branch being relatively large in diameter.Structure state one, two, three and four belongs to parallel machine
Structure, structure state five belong to serial mechanism, and structure state six, seven and eight belongs to hybrid mechanism, the lumbering delimber can in parallel, series connection and
Flexible conversion in hybrid mechanism has stronger adaptability.
