Abstract
The utility model relates to an electric saw for trimming trees, transferring power through cables between a unit head and a working head. Wherein, the unit head comprises a petrol generating set, while the working head comprises an electric motor, a speed reducer and circular saw blades or saw chains driven by the speed reducer. A plurality of shrinking rods and articulated elements are connected between the unit head and the working head, enabling the pruning height to reach 8-10 meters. Simultaneously, the working head can be turned to the required direction to trim tree branches in various directions, and the electric saw for cutting high branches of trees can also be used for topping high and large bamboos such as Mao bamboo, etc.
Description
Technical field: the utility model relates to a kind of saw that the trees branches of tall trees are repaired.
Background technology: at present the trees branches of tall trees finishing machine that uses have hand saws, pull Gao Zhiju, manually averruncator, manually perching knife, chain saw, electric chain saw, Tree chain saw, hand-held hydraulic pressure averruncator, vehicle-mounted hydraulic averruncator etc.Preceding four kinds is hand-operated tools, the operation effort, and production efficiency is low, and repaiies thick branch difficulty.Hand saws, chain saw and electric chain saw need operator's operation of climbing the tree, and human casualty accident easily takes place.Tree chain saw is owing to the transmission shaft structure complexity, and operational height is below 5 meters, and the price height, and power transmission shaft is fragile, and use cost is higher.The branch diameter that hand-held hydraulic pressure averruncator can be cut off is below 4 centimetres, clip injustice, and will join mobile Hydraulic Station, and the structure heaviness is so fail popularization.Vehicle-mounted hydraulic averruncator structure is huge, costs an arm and a leg, and working head is dumb, limited by surface condition, thereby also fails to promote the use of.More than the cutting range of two kinds of hydraulic pressure averruncators also all below 5 meters.The pruning of needs such as the high megaphanerophyte of some of key industry timber forest such as the living poplar of speed, Chinese tulip tree highly reaches 8-10 rice, and obviously existing facility fail to satisfy this requirement.
Summary of the invention:
The purpose of this utility model provides the hand-held Gao Zhiju of high efficiency that a kind of finishing highly reaches 8-10 rice.
The purpose of this utility model is achieved in that gasoline engine and generating set are fitted together, and constitutes unit head.Electromotor, decelerator and saw blade or saw chain etc. are fitted together, and form working head.Be connected energising cable in the expansion link between unit head and the working head with the multi-joint telescoping aluminium-alloy pipe.Adopt the moving structure of fax between unit head and the working head.The power of gasoline engine relies on electric transmission to pass on the decelerator, and does not adopt transmission shaft structure.Gasoline engine drives generator and sends electric current, passes on the electromotor that is contained in high bar upper end by cable, makes the electromotor high speed rotating.By passing to behind the decelerator on the mandrel, make mandrel again with suitable speed rotation.When on the mandrel saw blade being installed, the saw blade of high speed rotating can sawed-off branch.When on the mandrel drive sprocket being installed, can drive saw chain and do the high speed rotary motion, the saw chain that is bearing in the high speed rotary motion on the guide plate can sawed-off larger-diameter branch.Adopt the thin-wall aluminum alloy control of lightweight to make high bar, and adopt light material to make working head, make the weight of 8-10 rice Gao Zhiju little like this, people can lift and carry out the sawing operation.
Owing between gasoline engine and decelerator, adopt the cable transferring power, simplified transmission mechanism, so can realize the multi-joint telescoping of high bar easily, make working head can reach the height of 8-10 rice.Because the softness of cable adds upper hinge, just can realize the multi-faceted rotation of working head, carries out the sawing of various different directions, thus can the sawed-off easily branch that stretches to various directions, also can be used for section tip of a branch operation of the contour big bamboo of mao bamboon.Simultaneously, the high speed sawing of thin saw blade can obtain concordant saw kerf plane, helps arboreal growth, can improve wood quality.The degree of depth of going deep into saw kerf when saw blade and saw chain sawing is bigger, and can be from multi-direction deep, this make can be sawed-off the branch diameter up to more than 10 centimetres.In addition, electric gearratio power transmission shaft drive mechanism is simple, and cost is low, reliable operation, and its usage economy is good.
Description of drawings: the utility model is further specified below in conjunction with drawings and Examples.
Fig. 1 is embodiment one of the present utility model.
Fig. 2 is embodiment two of the present utility model.
Fig. 3 is embodiment three of the present utility model.
Fig. 4 is embodiment four of the present utility model.
Among the figure: 1, gasoline engine 2, generator 3, expansion link 4, cable 5, articulated elements 6, electromotor 7, decelerator 8, saw blade 9, drive sprocket 10, saw chain 11, guide plate 12, unit head 13, working head
Embodiment: during operation, gasoline engine (1) high speed rotating drives generator (2) rotary electrification.Electric current makes electromotor (6) rotation by the electromotor (6) that the cable (4) in the expansion link (3) leads to expansion link (3) upper end, again by decelerator (7), makes the saw blade (8) or drive sprocket (9) rotation that are installed on decelerator (7) output shaft.Drive sprocket (9) drives saw chain (10) and does the high speed rotary motion around guide plate (11).The saw chain (10) of saw blade of high speed rotating (8) or high speed rotary can carry out sawing to branch.Articulated elements (5) can be realized the various angles of inclination of saw blade (8) or guide plate (11), so that the branch of sawed-off various incline directions.When saw blade (8) level of approximation, can be used for section tip of a branch operation of the contour big bamboo of mao bamboon.Embodiment three and embodiment four no articulated elements (5), working head can not rotate, but structure is simpler.
Claims (3)
1, the moving Gao Zhiju of a kind of fax, it is characterized in that: adopted fax to move structure between unit head (12) and the working head (13), unit head (12) is made up of gasoline engine (1) and generator (2), working head (13) is made up of electromotor (6), decelerator (7) and saw blade (8) or drive sprocket (9), guide plate (11) and saw chain (10), be connected by expansion link (3) and articulated elements (5) between unit head (12) and the working head (13), the cable (4) in the expansion link (3) connects generator (2) and electromotor (6).
2, the moving Gao Zhiju of fax according to claim 1 is characterized in that: be connected with expansion link (3) between unit head (12) and the working head (13), expansion link (3) is made up of more piece thin-wall aluminum alloy pipe, can stretch.
