Abstract
The utility model discloses a two main shaft rotary tool structures of machine are felled to crawler -type intermediate cutting, it comprises the high -power gasoline engine (1) of power take off, friction clutch (2), two V area (6), main shaft a (3), main shaft b (4), jackshaft (5). Its working process is: power high -power gasoline engine (1) passes through friction clutch (2) with power and main shaft an and main shaft b are given in two V areas (6) transmission, realize through jackshaft (5) transition that main shaft b (4) are opposite with the direction of rotation of main shaft a (3) simultaneously. Friction clutch (2) are rationally matchd in high -power gasoline engine output shaft (1) can realize rotating automatically and stopping of main shaft. Bring capable transmission into through two V between friction clutch (2), main shaft a (3), main shaft b (4), jackshaft (5), high transmission efficiency when taking place the binding phenomenon in cutting process, can play overload protection to the saw bit.
Description
Technical field
The utility model relates to a kind of crawler type intermediate cutting harvester, the two main shaft rotary cutter structure of especially a kind of crawler type intermediate cutting harvester.
Background technology
At present, the forest plantation accumulation of China occupies first place in the world, and account for nearly 1/3rd of world's forest plantation area, average annual increment exceedes 1/2nd of world's increment, and China has become the fastest-rising country of the forest resources.China's Plantation Development is quick, has become the most important supply source of China's timber.The logging operation of forest plantation and shrub is significant to the ecological safety of China, timber safety guarantee.
China's forestry machinery development is more late, and the development work of forestry felling devices is in a backward condition for a long time, and mechanization degree is low compared with developed countries.At present, domestic forest zone logger mainly adopts chain saw.Its rotary cutter structure drives hilted broadsword tool by single main shaft, and cutting speed is comparatively slow, and production efficiency is low.
Summary of the invention
The purpose of this utility model is to provide the two main shaft rotary cutter structure of a kind of crawler type intermediate cutting harvester, and the power resources of this structure are high-power gasoline engines, and it can utilize limited space efficiently, provides enough power to drive lumbering device.This mechanism structure is simple, saving space, improves the safety of machine simultaneously.
To achieve these goals, the technical solution adopted in the utility model is: the high-power gasoline engine of the device that outputs power is arranged on guide rail, and power is passed to main shaft a and main shaft b by slip clutch and two V band by the high-power gasoline engine of power; Realize main shaft b by jackshaft transition contrary with main shaft a direction of rotation simultaneously.It is contrary that this power transmission process realizes two main shaft direction of rotation effectively, automatically can realize rotation and the stopping of main shaft, cost-saving, improves job security and efficiency simultaneously.
Accompanying drawing explanation
Fig. 1 is general view of the present utility model.
In figure: 1. high-power gasoline engine 2. slip clutch 3. main shaft a4. main shaft b5. jackshaft 6. pairs of V bands
Embodiment:
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail:
1. the two main shaft rotary cutter structure of novel crawler-type intermediate cutting harvester, it is with (6), main shaft a (3), main shaft b (4), jackshaft (5) to form by the high-power gasoline engine of Power output (1), slip clutch (2), two V.Its embodiment is: power is passed to main shaft a and main shaft b by slip clutch 2 and two V band 6 by the high-power gasoline engine of power (1); Realize main shaft b (4) by jackshaft (5) transition contrary with the direction of rotation of main shaft a (3) simultaneously.High-power output shaft of gasoline engine (1) Proper Match slip clutch (2) can realize automatic rotation and the stopping of main shaft.Transmission is carried out by two V band between slip clutch (2), main shaft a (3), main shaft b (4), jackshaft (5); transmission efficiency is high; when there is binding phenomenon in working angles, overload protection can be played to saw blade.
Claims (4)
1. the two main shaft rotary cutter structure of crawler type intermediate cutting harvester, it is with (6), main shaft a (3), main shaft b (4), jackshaft (5) to form by the high-power gasoline engine of Power output (1), slip clutch (2), two V, it is characterized in that: power is passed to main shaft a and main shaft b by slip clutch and two V band (6) by the high-power gasoline engine of power (1); Realize main shaft b by jackshaft (5) transition contrary with the direction of rotation of main shaft a simultaneously.
2. rotary cutter structure according to claim 1, is characterized in that: high-power output shaft of gasoline engine (1) Proper Match slip clutch (2) can realize automatic rotation and the stopping of main shaft.
3. rotary cutter structure according to claim 1, is characterized in that: realize main shaft b by jackshaft (5) transition contrary with the direction of rotation of main shaft a.
4. rotary cutter structure according to claim 1; it is characterized in that: between slip clutch (2), main shaft a (3), main shaft b (4), jackshaft (5), carry out transmission by two V band; transmission efficiency is high; when there is binding phenomenon in working angles, overload protection can be played to saw blade.
