Abstract
The utility model relates to a high handle oil saw, belonging to forest tree felling machinery; the utility model is composed of an engine, a centrifugal clutch, a chain wheel, a saw chain and a guide plate. Compared with the existing high handle oil saw, the differences lie in that a coupling shaft is fixed on the engine of the utility model; a coupling disk is sheathed on the coupling shaft; a positioning mechanism for circumferential direction is arranged on the coupling disk; two positioning holes are arranged on the coupling shaft; the positioning mechanism are matched with the positioning holes; an operating saw handle is fixed on the coupling disk. The change of the cutting direction of the high handle oil saw is realized by the whole rotation of an engine part and a working part; therefore, a speed reduction device is not needed and the utility model can meet the multifunctional requirements, such as felling tree, wood manufacture, etc. The utility model has the advantages of low cost, less malfunction and convenient operation.
Description
The utility model belongs to the forestry machinery technical field, and the height that relates in particular to a kind of hand-held harvest of forest trees is chain saw.
At present, the height of using on the market is divided into chain saw no deceleration device and is with two kinds in deceleration device, and no deceleration device is high can not to be rotated the working portion saw chain guide plate of chain saw, only adapts to a kind of function of cutting down trees; The band deceleration device is high can be rotated the working portion saw chain guide plate of chain saw, it is that rotation by deceleration device realizes, therefore both can cut down trees, but producing material again because it has set up deceleration device, makes complex structure, the cost height, especially a pair of displacement bevel gear in the deceleration device, the processing technology complexity, and noise is bigger during work.
The purpose of this utility model is to provide a kind of no deceleration device, but not only can cut down trees but also the height of producing material chain saw.
For achieving the above object, the employing technical scheme is as follows: height contains engine to chain saw, centrifugal clutch, sprocket wheel, saw chain, guide plate, engine connects centrifugal clutch, centrifugal clutch connects sprocket wheel, sprocket wheel drives saw chain and moves on guide plate, particularly on engine, fix a coupling spindle, one tie-plate is set in addition, tie-plate is sleeved on the coupling spindle other end, circumferential detent mechanism is arranged on the tie-plate, mutually perpendicular two locating holes are arranged on the coupling spindle, and the circumferential detent mechanism on locating hole and the tie-plate cooperatively interacts, and the operation saw is being fixed on the tie-plate.
Detent mechanism on the tie-plate is made up of positioning tie bar, spring, and the locating hole on positioning tie bar and the coupling spindle cooperatively interacts.
The utility model height adopts suit tie-plate on the coupling spindle to chain saw, and the structure of circumferential detent mechanism is set on tie-plate, realized the spin orientation function of engine, the rotation by engine makes the and then rotation of saw chain guide plate, just can adapt to the job requirement of different sawing directions.Chain saw compared reduced deceleration device with the height of band deceleration device, make structure more simple, and function is constant, also overcome no deceleration device height simultaneously the shortcoming that chain saw can not rotate, have easy for operation, simple in structure, the characteristics that cost is low.
Below in conjunction with the embodiment accompanying drawing the utility model is described in further detail.
Fig. 1 is high the transmission principle schematic diagram of chain saw.
Fig. 2 is high the structural principle schematic diagram of chain saw.
Fig. 3 is high the rotation of chain saw and operation part structural representation.
Among Fig. 1; engine is as motive power; drive centrifugal clutch 2 rotations by engine crankshaft 1; when engine is in idling mode; its rotating speed be lower than centrifugal clutch 2 in conjunction with rotating speed; centrifugal clutch 2 is in released state, and working portion does not turn round, and engine is played overload protective function.When engine reaches certain rotating speed, centrifugal clutch 2 combinations, working portion running this moment promptly drives sprocket wheel 3 by centrifugal clutch 2, and sprocket wheel 3 drives saw chain 4 and moves on guide plate 5, finishes the sawing function.High among Fig. 1 do not have deceleration device to chain saw, and the height that deceleration device is arranged is chain saw, and its deceleration device is installed among Fig. 1 between the centrifugal clutch 2 and sprocket wheel 3, and the change of sawing direction realizes by rotational speed-reducing device.
Fig. 2 shows architectural feature of the present utility model, 6 mean engines part and working portion among the figure, rotation and operation part link to each other with 6, its connected mode is to fix a coupling spindle 7 on engine, and tie-plate 9 is sleeved on the coupling spindle 7, is provided with circumferential detent mechanism 8 on tie-plate 9, by circumferential detent mechanism 8, the rotation of control coupling spindle, thus realize the orientation rotation of engine section and working portion is controlled, and the operation saw is fixed on 10 on the tie-plate 9.Fig. 3 shows the concrete structure of rotation and operation part, mandrel 11 is fixedlyed connected with engine crankshaft 1 among Fig. 1, coupling spindle 7 is fixedlyed connected with mandrel 11, tie-plate 9 is sleeved on the other end of coupling spindle 7, coupling spindle 7 can rotate in tie-plate 9, circumferential detent mechanism 8 on the tie-plate 9 is made up of positioning tie bar 12 and spring 13, the locating hole 14,15 that matches with positioning tie bar 12 is arranged on coupling spindle 7, locating hole 14,15 is orthogonal, and two holes 16,17 on the tie-plate 9 are used for the fitting operation saw 10.Because engine section and working portion are fastenedly connected, therefore, the utility model is high to be the change of chain saw sawing direction to rotate by the integral body of engine section and working portion to realize, when the needs rotation, when realizing another sawing function, only need and to pull out the locating hole of positioning tie bar from coupling spindle, rotate coupling spindle, and place another locating hole to get final product positioning tie bar.The effect of spring is to reset, and makes the location more reliable, the design of two locating holes, and the requirement of cutting down trees is satisfied in the one hole, and another hole is suitable for the producing material needs.
Rotary positioning mechanism also can adopt detent mechanism is installed on tie-plate, locating hole is set on the engine realizes spinfunction; In addition, also can adopt detent mechanism is installed on engine, locating hole is set on the coupling spindle realize spinfunction.
This height is simple in structure chain saw, and does not need deceleration device, can realize the change of sawing direction, can satisfy cut down trees, the multi-functional requirement such as producing material, to the BG of use amount maximum in the market33Type is high chain saw, improves a little, can realize having Cost is low, and fault is few, easy to operate characteristics.
