Detailed description of the invention:
Below in conjunction with drawings and Examples, technical scheme is further described.
As shown in Fig. 1, Fig. 9 and Figure 12, restructural of the present invention lumbering delimber, concrete structure and annexation be:
nullThis lumbering delimber its first side lever 7 when initial structure state is connected with base 8 by the 3rd straight pin 9，First side lever 7 is connected with the first sliding bar 5 with the connected mode of moving sets，First circular arc flap 6 is arranged on the first side lever 7，First sliding bar 5 is connected with first connecting rod 3 by the second straight pin 4，Chopping disk 1 is connected with first connecting rod 3 by the first straight pin 2，First connecting rod 3 is connected with second connecting rod 10 by the first straight pin 2，Second connecting rod 10 is connected with the second sliding bar 13 by the 4th straight pin 11，Second sliding bar 13 is connected with the second side lever 14 with the connected mode of moving sets，Second circular arc flap 12 is arranged on the second side lever 14，Second side lever 14 is connected with base 8 by the 5th straight pin 15，First side lever 7 is welded with the fixing plate washer 16 of circular arc，First sliding bar 5 is welded with moving block 17，First side lever 7 and the second side lever 14 have identical structure，First sliding bar 5 and the second sliding bar 13 have identical structure.
As the graph shows, described first side lever 7 is welded with the fixing plate washer 16 of circular arc, is used for the first circular arc flap 6 is installed.
As shown in Figure 10, on described first side lever, 7 have elongated slot, and the first sliding bar 5 can slide in elongated slot.
As shown in figure 12, described first sliding bar 5 is welded with moving block 17.
The operation principle of the present invention is: this lumbering delimbing mechanism's state conversion is it is crucial that the peculair motion that can convert between moving sets and revolute pair is secondary, this kinematic pair is used in the connection between the first side lever 7 and the first sliding bar 5, the connection between the second side lever 14 and the second sliding bar 13.For the connected mode of the first side lever 7 and the first sliding bar 5, the operation principle that this peculair motion is secondary being described, between the second side lever 14 and the second sliding bar 13, the shift theory of connected mode is also identical.When moving in first sliding bar 5 elongated slot in the first side lever 7, the connected mode between the first sliding bar 5 and the first side lever 7 is that moving sets connects, as shown in Figure 10；When the first sliding bar 5 moves to the top of the first side lever 7, moving block on first sliding bar 5 17 grades is lived by the fixing plate washer 16 of circular arc, now the first circular arc flap 6 rotates 180 ° to underface, it is made to encase the moving block 17 on the first sliding bar 5, now the first side lever 7 is that revolute pair is connected with the connected mode of the first sliding bar 5, as shown in figure 11.Connected mode between the first side lever 7 and the first sliding bar 5 is that moving sets connects, connected mode between second side lever 14 with the second sliding bar 13 is that moving sets is when being connected and do not have any rod member to overlap, mechanism is in original state, as shown in Figure 1, now the space of mechanism and rigidity are all bigger, but its local motility is poor, it is suitable for the trunk of major diameter is cut down；When the connected mode of the first side lever 7 with the first sliding bar 5 is that revolute pair is connected, second side lever 14 and the connected mode of the second sliding bar 13 are that moving sets is when being connected and do not have any rod member to overlap, mechanism is in the second structure state, as shown in Figure 2, now big than initial structure state of the space of mechanism, but rigidity declines to some extent, it is suitable for the trees that felling diameter is moderate；When the connected mode of the first side lever 7 with the first sliding bar 5 is that revolute pair is connected, second side lever 14 and the connected mode of the second sliding bar 13 are that revolute pair is when being connected and do not have any rod member to overlap, mechanism is in the 3rd structure state, as shown in Figure 3, now the work space of mechanism is maximum, but rigidity is poor, it is suitable for the trunk that the diameter of felling higher position is less；When the connected mode of the first side lever 7 with the first sliding bar 5 is that revolute pair is connected, when second side lever 14 and the connected mode of the second sliding bar 13 are that revolute pair is connected and the first side lever 7 and the second side lever 14 all overlap with base 8, mechanism is in the 4th structure state, as shown in Figure 4, now the rigidity of mechanism and space are all moderate, are suitable for the branch that diameter is general is carried out delimbing；When the connected mode of the first side lever 7 with the first sliding bar 5 is that revolute pair is connected, second side lever 14 is that revolute pair is connected with the connected mode of the second sliding bar 13, first side lever 7 and the second side lever 14 all overlap with base 8, first sliding bar 5 overlaps with the second sliding bar 13, when first connecting rod 3 overlaps with second connecting rod 10, mechanism is in the 5th structure state, as shown in Figure 5, the now motility of mechanism is the strongest, is suitable for the branch of medium-small diameter is carried out delimbing；When the connected mode of the first side lever 7 with the first sliding bar 5 is that moving sets is connected, when second side lever 14 is that moving sets is connected and first connecting rod 3 overlaps with second connecting rod 10 with the connected mode of the second sliding bar 13, mechanism is in the 6th structure state, as shown in Figure 6, now the work space of mechanism is moderate, local motility is relatively strong, is suitable for the trunk that diameter is moderate being cut down and larger-diameter branch being carried out delimbing；When the connected mode of the first side lever 7 with the first sliding bar 5 is that revolute pair is connected, when second side lever 14 is that moving sets is connected and first connecting rod 3 overlaps with second connecting rod 10 with the connected mode of the second sliding bar 13, mechanism is in the 7th structure state, as shown in Figure 7, now work space is bigger than the 6th structure state, ratio of rigidity the 6th structure state is smaller, and local motility is strong, is suitable for the little trunk of centering and cuts down；When the connected mode of the first side lever 7 with the first sliding bar 5 is that revolute pair is connected, when second side lever 14 is that revolute pair is connected and first connecting rod 3 overlaps with second connecting rod 10 with the connected mode of the second sliding bar 13, mechanism is in the 8th structure state, as shown in Figure 8, now the work space of mechanism is bigger, rigidity is moderate, is suitable for the branch being relatively large in diameter is carried out delimbing.Structure state one, two, three and four belongs to parallel institution, and structure state five belongs to serial mechanism, and structure state six, seven and eight belongs to hybrid mechanism, this lumbering delimber can in parallel, series connection and hybrid mechanism flexible conversion, there is stronger adaptability.
