Abstract
The invention relates to field of forestry felling machinery, a feed roller of combined feller which comprises two parts as spike teeth and roller matrix, with characteristic of multiple vertical spike teeth distributed around circular pattern of the roller matrix. The top ( shown in picture 3) of spike-tooth feed roller enters cylindrical surface of tree trunk, with its rotation bringing steady and fast axial movement to the trunk. The invention has advantages such a simple structure, convenient assembly and use, highly accurate grinding, wide range of application and low cost, etc.
Description
Technical field
The present invention relates to forestry logger field, specifically a kind of associating tree-dozer felling head feed roller.
Background technology
At present, along with improving constantly of human cost, the felling of the trees in high volume such as forest farm, farm and municipal administration can not be single again
One ground relies on manpower, is badly in need of one lumbering special purpose machinery and replaces the realization that can link up of manpower, this lumbering special purpose machinery to cut down, remove
Branch, measure, a series of actions of peeling.The outer work face of existing associating tree-dozer felling head feed roller is straight-tooth surface knot
Structure, when processing felled tree, causes charging unstable and charging speed due to outer work face and the contact surface defect of felled tree
Degree is slow, inefficiency.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, easy to install, grinding accuracy is high, applied widely, become
This low associating tree-dozer felling head feed roller, solves the charging rate in background technology slow, ineffective shortcoming.
It is an object of the invention to be achieved through the following technical solutions:
The nail shape toothing technical characteristic of the present invention includes tooth depth, welding contact area, inclination angle of inclined plane, distribution density etc..
The roll shaft of the present invention need to coordinate with described nail shape tooth, and is provided with cross through hole in axle side.
Described roll shaft cross through hole has installation to be fixed and dynamic balancing regulatory function.
As seen from the above technical solution provided by the invention, the associating tree-dozer spike-tooth type charging that the present invention provides
Roller.Owing to the contact area of spike-tooth (such as Fig. 3) Yu the arcwall face of roll shaft welding position is s, tooth depth is h, inclined-plane and bottom surface angle
For α, tooth base area account for roll shaft area 15% (as Fig. 1,2), roll shaft side is provided with 11 cross through hole.Simple in construction, peace
Fill easy to use, grinding accuracy is high, applied widely, charging is stable, working performance high.
Accompanying drawing explanation
Fig. 1 is that the axle combining tree-dozer spike-tooth type feed roller in the embodiment of the present invention measures intention；
Fig. 2 is the schematic top plan view combining tree-dozer spike-tooth type feed roller in the embodiment of the present invention；
Fig. 3 is spike-tooth schematic diagram in the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the embodiment of the present invention is described in further detail.
Spike-tooth type feed roller work time crown (such as Fig. 3) end enter the trunk face of cylinder, its rotate drive trunk do stablize fast
Moving axially of speed.Wherein welding position contact area s, tooth depth h, inclined-plane and bottom surface angle α, spike-tooth distribution density all can be with realities
Border job requirement changes.
Due to the fact that employing said structure, have easy to install, grinding accuracy is high, applied widely, charging is steady
The advantages such as fixed, charging rate is fast.
The above, the only present invention preferably detailed description of the invention, but protection scope of the present invention is not limited thereto,
Any those familiar with the art in the technical scope of present disclosure, the change that can readily occur in or replacement,
All should contain within protection scope of the present invention.Therefore, protection scope of the present invention should be with the protection model of claims
Enclose and be as the criterion.
