Description
Technical field
The present invention relates to a kind of feed roller profiling clamping devices of device of lumbering, the felling for forest farm trees.
Background technique
When the feed roller of lumbering device carries out trunk clamping currently on the market, left and right feed roller is opposing arcs fortune
Dynamic, left and right feed roller forms the angle of a linear change, is variation to the chucking power of trunk, clip position, undesirable
, cause trunk charging to damage when frictional force is big, trunk is clamped more serious, in addition for the trunk of major diameter, left and right charging
Roller clamping resultant force pushes out trunk, so lumbering device needs a pair of of main clamp and a pair of leading branch cutter to be distributed in charging
Before and after roller, trunk can be just embraced, such lumbering apparatus structure is complicated, at high cost.
Summary of the invention
Problem solved by the invention is to provide a kind of feed roller profiling clamping device of device of lumbering, in fill process
In, with the variation of trunk diameter, can efficient, laborsaving, safely profiling clamping and transmission trunk, assist tree-dozer efficiently
Do mechanization operation is carried out, in addition The present invention reduces the leading branch cutters of a pair of lumbering device, only retain a pair of of band delimbing function
Main clamp simplifies mechanism, reduces machine cost.
To solve the above problems, the technical solution of the invention is as follows: a kind of feed roller profiling clamping machine for device of lumbering
Structure, including lumbering device body frame, left rocking bar, left feed roller mounting rack, left curve cam, left feed roller, synchronising (connecting) rod, driving oil
Cylinder, right rocking bar, right feed roller mounting rack, right curve cam, right feed roller and driven roller, specific structure and connection relationship are as follows:
The lumbering device body frame, left rocking bar, synchronising (connecting) rod and right rocking bar form a four-bar mechanism, and drive cylinder is
The power source of parallel motion, left feed roller mounting rack and left rocking bar are hinged, and right feed roller mounting rack and right rocking bar are hinged,
Driven roller and lumbering device body frame are hinged, wherein left feed roller mounting rack includes a left curve cam, right feed roller installation
Frame includes a right curve cam, and left curve cam, right curve cam and two driven rollers form two pairs of cam profiling mechanisms,
Left feed roller is mounted on left feed roller mounting rack, and right feed roller is mounted on right feed roller mounting rack, in four-bar mechanism and
Under the compound motion effect of cam profiling mechanism, left feed roller and right feed roller do the movement close to translation, in fill process,
With the variation of trunk diameter, profiling clamps trunk.
The left rocking bar and lumbering device body frame are hinged, and right rocking bar and lumbering device body frame are hinged, synchronising (connecting) rod and a left side
Rocking bar and right rocking bar hingedly form a four-bar mechanism.
The driven roller is two, and two driven roller rotation directions are opposite.
Of the invention has the prominent advantages that:
The cooperative movement for dexterously using four-bar mechanism and cam mechanism solves lumbering device in fill process,
The profiling of stem diameter changes clamps problem, reduces charging frictional force, while can reduce a pair of leading branch cutter, simplifies machine
Structure reduces machine cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the feed roller profiling clamping device of lumbering device of the present invention.
Fig. 2 and Fig. 3 is the mechanical movement schematic diagram of the feed roller profiling clamping device of lumbering device of the present invention.
In the figure, it is marked as lumbering device body frame 1, left rocking bar 2, left feed roller mounting rack 3, left curve cam 3-1, left charging
It is roller 4, synchronising (connecting) rod 5, drive cylinder 6, right rocking bar 7, right feed roller mounting rack 8, right curve cam 8-1, right feed roller 9, driven
Idler wheel 10, trunk 11.
Specific embodiment
Technical solution of the present invention is further illustrated below by way of drawings and examples.
As shown in Figure 1 to Figure 3, the feed roller profiling clamping device of lumbering device of the present invention, including lumbering device master
It is frame 1, left rocking bar 2, left feed roller mounting rack 3, left curve cam 3-1, left feed roller 4 belonging to left feed roller mounting rack 3, synchronous
Connecting rod 5, drive cylinder 6, right rocking bar 7, right feed roller mounting rack 8, right curve cam 8-1, the right side belonging to right feed roller mounting rack 8
Feed roller 9 and driven roller 10, specific structure and connection relationship are as follows:
The lumbering device body frame 1, left rocking bar 2, synchronising (connecting) rod 5 and right rocking bar 7 form a four-bar mechanism, driving oil
Cylinder 6 is the power source for driving parallel motion.Left feed roller mounting rack 3 and left rocking bar 2 are hinged, right feed roller mounting rack 8
Hinged with right rocking bar 7, driven roller 10 and lumbering device body frame 1 are hinged, and left feed roller mounting rack 3 includes a left curve cam
3-1, right feed roller mounting rack 8 include a right curve cam 8-1, left curve cam 3-1, right curve cam 8-1 and two from
Dynamic idler wheel 10 constitutes two pairs of cam profiling mechanisms.Left feed roller 4 is mounted on left feed roller mounting rack 3, right feed roller 9 is installed
On right feed roller mounting rack 8, under four-bar mechanism and the effect of the compound motion of cam profiling mechanism, left feed roller 4 and the right side
Feed roller 9 does the movement close to translation, and in fill process, with the variation of trunk diameter, profiling clamps trunk.
The left rocking bar 2 and lumbering device body frame 1 is hinged, and right rocking bar 7 and lumbering device body frame 1 are hinged, synchronising (connecting) rod 5
A four-bar mechanism is hingedly formed with left rocking bar 2 and right rocking bar 7.
Operation principle and process:
Device is felled in fill process, drive cylinder 6 is shunk, and drives left rocking bar 2 to turn counterclockwise by four-bar mechanism
Dynamic, right rocking bar 7 rotates clockwise, and then left rocking bar 2 drives left curve cam 3-1 movement, right rocking bar 7 to drive right curve cam 8-
1 movement, under the action of cam mechanism, left feed roller 4 is to similar translational motion is done in upper right side, right feed roller 9 is done to upper left side
Similar translational motion, to realize that the profiling to trunk clamps with the variation of trunk diameter.
