Description
Technical field
This utility model relates to a kind of gang tool, particularly to a kind of tree felling machine gang tool。
Background technology
Tree felling machine is made up of head and main body two parts, and head is for by being sized felling and blocking trees, remove branch, and main body is used for carrying head and complete machine walking。Tree felling machine gang tool is the kernel component of head section, and traditional tree felling machine gang tool hardness and wearability are relatively low, and service life is short。
Summary of the invention
In order to solve the problems referred to above, this utility model provides a kind of hardness and wearability is high, the automatic tree felling machine cutter of long service life。
For achieving the above object, the technical scheme that this utility model adopts is: a kind of tree felling machine cutter automatically, including before fixing felling cutter, front movable felling cutter, feeding wheel-drive motor, rear movable felling cutter, rear fixing felling cutter, block chain saw, clamping cylinder and headstock。It is arranged above with clamping cylinder at headstock, fixing felling cutter before the front end of headstock is provided with, after the rear end of headstock is provided with, fixes felling cutter and blocks chain saw, movable felling cutter, drawing-inroller and driving motor, rear movable felling cutter before being sequentially provided with from front to back below headstock。
Described fixing felling cutter is fixed on headstock, the circular arc that outline top is angle 135 °, radius 175mm of fixing felling cutter, the cutting edge of fixing felling cutter is 27.5 °, 13 ° of relief angles, enough sharp guarantee higher felling quality and less felling resistance, with standing part orthodrome transition, possess higher-strength。
The work surface of described forward and backward movable felling cutter is involute contour, and front fixing felling cutter forms sub-circular with front movable felling cutter；Rear fixing felling cutter forms sub-circular with rear movable felling cutter, it is ensured that optimum debranching effect in design felling diameter range。
The bottom surface of described forward and backward fixing felling cutter and forward and backward movable felling cutter is provided with the alternate coatings of titanium carbide and titanium carbonitride, alternate coatings reaches 40 layers, increases hardness and the wearability of tool surface, reduces coefficient of friction, reduce the generation of kinetic equation loss and built-up edge, extend cutter life。
The cutting edge 27.5 ° of front movable felling cutter, T-shaped section, back side cutting edge 50 °, Z-type bottom surface contact area is little。The cutting edge 27.5 ° of rear movable felling cutter, T-shaped section, the contact area that waveform bottom shape is less, enough sharp guarantee higher felling quality and less felling resistance, possesses sufficient intensity, the T-shaped facade of gradually reducing property progressively reduces, and under the premise guaranteeing intensity, reduces quality and material consumption。For preventing embedding trees excessively deep, front movable felling cutter, rear movable cutter of cutting down machined the reflex angle of 4.5 × 30 °, 2 × 22 ° respectively at cutting edge。
Before described, fixing felling edge is towards trunk small end, is used for cutting down tree head end branch, and rear fixing felling edge, towards the big end of trunk, is used for cutting down tree root end branch。
The beneficial effects of the utility model are: debranching is effective, and felling quality is high, felling resistance is little, and the hardness of tool surface and wearability are high, reduce coefficient of friction, reduce the generation of kinetic equation loss and built-up edge, extend cutter life。
Accompanying drawing explanation
Fig. 1 is this utility model structural representation。
In figure: fixing felling cutter before 1, movable felling cutter, 3 drawing-inrollers and drive motor, movable felling cutter after 4, fixing felling cutter after 5,6 block chain saw, (7-12) clamping cylinder, 13 headstocks before 2。
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, this utility model is further described:
As shown in Figure 1, a kind of tree felling machine cutter automatically, including before fixing felling cutter (1), front movable felling cutter (2), drawing-inroller and drive motor (3), rear movable felling cutter (4), rear fixing felling cutter (5), block chain saw (6), clamping cylinder (7-12) and headstock (13)。It is arranged above with clamping cylinder (7-12) at headstock (13), fixing felling cutter (1) before the front end of headstock (13) is provided with, after the rear end of headstock (13) is provided with, fixes felling cutter (5) and blocks chain saw (6), movable felling cutter (2), drawing-inroller and driving motor (3), rear movable felling cutter (4) before being sequentially provided with from front to back below headstock (13)。The holding tightly of trees, cut down, feeding, debranching, block and all complete by electric-hydraulic proportion transmission and numerical control system。
During the non-job state of tree felling machine, blocking chain saw (6) end and down and regain, clamping cylinder (7-12) is retracted, front movable felling cutter (2), drawing-inroller and drive motor (3), rear fixing felling cutter (5) to open。
Cut down trees operation time, head is in plumbness, under fuselage control move to touch wait cut down trees wood time, clamping cylinder (7-12) stretches out, trunk is held in front movable felling cutter (2), drawing-inroller and driving motor (3), afterwards fixing felling cutter (5) tightly, block chain saw (6) to run up, and the disconnected trees of effect lower swing felling of hydraulic jack。Then head and trees keep flat, drawing-inroller and drive motor (3) high speed rotating, promote trees high speed play, when through front fixing felling cutter (1), front movable felling cutter (2), are broken apart by chopping by branch。Drawing-inroller and driving motor (3) coordinate blocks chain saw (6), can be blocked by trees according to the length set。Bark can be taken off and block with root branch by rear movable felling cutter (4), rear fixing felling cutter (5)。
Trees are at front movable felling cutter (2), drawing-inroller and the clamped condition driving motor (3), rear movable felling cutter (4) in sum, rely on and drive the driving force of motor to overcome grip friction power to realize longitudinal feeding, require under the premise that trees do not come off under gravity, front movable felling cutter (2), drawing-inroller and drive motor (3), rear movable felling cutter (4) have minimum clamping force and and trees between frictional force。Clamping force is automatically adjusted by electro-hydraulic proportional valve hydraulic control system, and planform and the coefficient of friction of front activity felling cutter (2), rear movable felling cutter (4) and trees contact portion are the keys reducing frictional force。Branch felling process completes in trees high speed transfer process, it is necessary to cutter is enough sharp and possesses sufficient intensity。And the branch within the scope of intended diameter is removed to optimum efficiency by cutter after combination as far as possible。
Cutting down cutter in this utility model and combined with movable felling cutter by fixing felling cutter, fixing felling cutter is made up of front fixing felling cutter (1) and rear fixing felling cutter (5)；Movable felling cutter is made up of front movable felling cutter (2) and rear movable felling cutter (4)。Front movable felling cutter (2) is close similar with the structure of rear movable felling cutter (4), and front fixing felling cutter (1) is close with rear fixing felling cutter (5) structure, and front fixing felling cutter (1) cutting edge, towards trunk small end, is used for cutting down tree head end branch。Rear fixing felling cutter (5) cutting edge, towards the big end of trunk, is used for cutting down tree root end branch。
Felling cutter adopts W18Cr4V high-speed steel to manufacture, possess higher hardness and wearability, enough intensity and toughness, good manufacturability (welding, heat treatment, machining and grinding performance etc.), possess under the machining condition of high speed and the load that withstands shocks, keep the sharp keen performance of cutting for a long time。Fixing felling cutter is fixed on headstock (13), and outline top is R175 circular arc, 135 ° of angles。Movable felling cutter work surface is involute contour, and fixing felling cutter forms sub-circular with front movable felling cutter (2), rear movable felling cutter (4) respectively, it is ensured that optimum debranching effect in design felling diameter range。
