Abstract
The utility model discloses a high reach chain saw with variable sawing angles, which comprises a gearbox, a saw chain guide plate, a rotational baseplate, a saw chain and a locking rod, etc.; an output shaft and a transmission shaft of the gearbox are arranged in the shape of an L, and the output shaft extends out of the gearbox cover; the rotational baseplate is sleeved on the gearbox cover and is screwed in to press on the gearbox cover through ring nuts, and the saw chain guide plate is fixedly connected on the rotational baseplate; a chain wheel is arranged on the top end of the output shaft, the saw chain is sleeved at the edge of the saw chain guide plate and is meshed with the chain wheel; moreover, the transmission shaft is connected with a prime mover, the locking rod is hinged at a side of the gearbox; a gear ring is arranged on the bottom part of the rotational baseplate, and a pawl meshed with the gear ring is arranged on the locking rod. The saw chain guide plate of the utility model can rotate around the axes of the output shaft of the gearbox, and the rotation can be locked in different angles, so that the sawing operation of branches, wood or other materials can be performed with a sawing angle of more reasonable and laborsaving; therefore the high reach chain saw has the advantages of high operating efficiency and is time-saving and labor-saving.
Description
Technical field
The utility model relates to a kind of cutting tool, specifically a kind of Tree chain saw that is used for the sawing variable-angle that gardening is pruned, forest is felled.
Background technology
Existing sawing chain saw, its saw chain guide plate, saw chain can not rotate with respect to the output shaft of gear-box, when being used for gardening pruning sawing, can't adjust and change sawing angle according to the growth situation of limb, production efficiency is low when causing finishing cutting branch, has not only expended muscle power but also inconvenience during use.
Summary of the invention
The purpose of this utility model is the Tree chain saw of a kind of sawing variable-angle of providing at the deficiencies in the prior art, and it is simple in structure, easy to operate, has not only saved muscle power but also very convenient during use.
The concrete technical scheme that realizes the utility model purpose is:
A kind of Tree chain saw of sawing variable-angle, it comprises gear-box, saw chain guide plate, rotary bottom plate, saw chain and locking rod, and the output shaft and the power transmission shaft of gear-box is the setting of " L " type, and output shaft stretches out gear box cover; Rotary bottom plate is sleeved on the gear box cover, and is screwed into by the round nut that can regulate the degree of compressing and is pressed on the gear box cover, and the saw chain guide plate is fixedly connected on the rotary bottom plate; The output shaft top is provided with sprocket wheel, and saw chain is sleeved on saw chain guide plate edge and does gyration by sprocket engagement; Power transmission shaft connects prime mover; Locking rod is articulated in gear-box one side; The rotary bottom plate bottom is provided with gear ring, and locking rod is provided with ratchet, ratchet and gear ring engagement and locking gear ring.
Saw chain guide plate of the present utility model comprises that saw chain can rotate around the output shaft axis of gear-box, and this rotation may be locked in different angles, be convenient to more reasonable, more sawing angle in labour-saving is carried out the sawing operation of branch, timber or other material, high efficiency, time saving and energy saving.

Embodiment
Consult Fig. 1, it comprises gear-box 1, saw chain guide plate 2, rotary bottom plate 3, saw chain 4 and locking rod 5 etc. the utility model, and the output shaft 7 and the power transmission shaft 8 of gear-box 1 are the setting of " L " type, and output shaft 7 stretches out gear box cover 9; Rotary bottom plate 3 is sleeved on the gear box cover 9, and is screwed into round nut 12 and is pressed on the gear box cover 9.Regulate the degree of tightening of the external screw thread 91 on round nut 12 and the gear box cover, rotary bottom plate 3 can only be rotated around the axis of output shaft 7, and can axial float not arranged with gear box cover 9.Saw chain guide plate 2 is fixedly connected on the rotary bottom plate 3; Output shaft 7 tops are provided with sprocket wheel 10, and saw chain 4 is sleeved on saw chain guide plate 2 edges and does gyration with sprocket wheel 10 engagements; Power transmission shaft 8 connects prime mover 11; Locking rod 5 is articulated in a side of gear-box 1; Rotary bottom plate 3 bottoms are provided with gear ring 31, and locking rod 5 is provided with ratchet 51, ratchet 51 and gear ring 31 engagements and locking gear ring 31.
Consult Fig. 2, when the utility model used, if be used for the felling of forest, saw chain guide plate 2 was implemented operation with power transmission shaft 8 under parastate; When being used for gardening pruning cutting, when especially pruning the limb of tall and big forest, need to adjust the angle of saw chain guide plate 2 and power transmission shaft 8, detailed process is: open locking rod 5, the ratchet 51 of locking rod 5 heads is broken away from gear ring 31, rotate saw chain guide plate 2 and make rotary bottom plate 3 rotate required angle (angle between rotary bottom plate 3 and the power transmission shaft 8 can be adjusted) in 60-300 °.Close up locking rod 5, make ratchet 51 and gear ring 31 engagements on the locking rod 5, rotary bottom plate 3 is fixed, and angle adjustment finishes, and can carry out sawing to limb.
The utility model is by adjusting the angle between saw chain guide plate 2 and the power transmission shaft 8, can change operator's application of force angle, simultaneously can be by the gravity of Tree chain saw self, alleviate operator's application of force burden, not only saved muscle power but also very convenient during use, and can make saw chain to better proximity being arranged according to by the self-sow angle adjustment guide plate 2 of saw branch and the angle between the power transmission shaft 8 by the saw branch.
