Abstract

The invention relates to a tree finishing device, which comprises a main power input, an auxiliary power input and an actuator, and is characterized in that the main power input comprises a wire puller, a spiral spring, a one-way overrunning clutch with a pusher dog, and a ratchet and pawl, and is located on a middle lower part of the whole device; the auxiliary power input is formed by a direct-current motor, and is located on one side of an upper part of the whole device; and an actuating component is a saw bit and is located on an opposite side of the direct-current motor. The tree finishing device realizes the transfer of energy through high-efficient gear transmission, and a gear has a compact structure, a small overall size and a light weight. The spiral spring is accumulated by adopting manpower externally, so that the energy is saved compared with a lopper chain saw, and the labor capacity is reduced compared with an old method. Therefore, the device can enable tree finishing operation to be carried out high-efficiently and safely, and has the advantages of low cost, energy conservation and environment protection.

Description

The reshaping of trees device

Technical field

The present invention relates to a kind of garden tool set of reshaping of trees, especially adopt clockwork spring as major impetus and the dc motor reshaping of trees device as auxiliary power.

Background technology

At present both at home and abroad, the pruning in fields such as urban afforestation, gardens and orchards for the less arbor trees of diameter, what still adopt is the method for old-fashioned ascending stair beta pruning or stay cord beta pruning, these two kinds of method labour intensity are large, inefficiency; The branch larger for diameter uses high branch chain saw usually, although high efficiency, weight is large, operation is relatively more dangerous, fuel consume has pollution, and use cost is higher.

Summary of the invention

The purpose of this invention is to provide a kind of reshaping of trees device, the less labour intensity of this reshaping of trees device energy, efficient is high, and weight is lighter, handling safety, fuel consumption and cost are not low.

The technical solution used in the present invention is: a kind of reshaping of trees device comprises major impetus input, auxiliary power input and executing agency.The major impetus input comprises wire grip, clockwork spring, band pusher dog mono-directional overrun clutch, ratchet and pawl, is positioned at the complete machine middle and lower part; The auxiliary power input is made of dc motor, is positioned at complete machine top one side; Execution unit is saw blade, is positioned at the relative side of dc motor.Dc motor is bolted on the shell, and the main shaft of dc motor links to each other with the gear I by the holding screw location, gear I and the engagement of gear II; The gear II is installed on the main shaft, and an end of main shaft is installed on the shell by bearing, and seals with top bearing cover, and the other end of main shaft stretches out outside the shell, and its top is connected with saw blade with stop washer by nut; Gear II and the engagement of gear III; The gear III is installed on the gear III axle, and an end of gear III axle is installed on the shell by bearing, and uses the lower bearing end cap seal; The gear III is installed on the gear IV axle by the individual event bearing simultaneously, and an end of gear IV axle is installed on the shell by bearing, and uses the lower bearing end cap seal; The gear IV is installed on the gear IV axle, gear IV and the engagement of gear V, the gear V is installed on the winder, winder is fixed on the shell by bearing, and end cap seal is arranged, and stretch out outside the shell on the top of winder, winder stretches out housing parts ratchet and clockwork spring is installed from inside to outside successively, ratchet links to each other with ratchet, establishes a clockwork spring protective cover in the shell outside, and ratchet, clockwork spring and ratchet are in this clockwork spring protective cover; Also linking to each other with band pusher dog mono-directional overrun clutch of gear V, band pusher dog mono-directional overrun clutch is installed on the wire grip axle, the wire grip axle is installed on the shell by bearing, the top of wire grip axle is stretched out outside the shell and is connected with wire grip, the wire grip cover is installed in the outside of shell, and it is inner that wire grip is hidden in the wire grip cover; Holding rod links to each other by nut with shell, and at the fixing wire grip handle of holding rod one end, the wire grip handle is connected by backguy with wire grip.

The kind of drive of the present invention, such as accompanying drawing 2, wire grip, band pusher dog mono-directional overrun clutch, clockwork spring consist of clockwork spring accumulation of energy driving-chain; Clockwork spring, gear V, gear IV, unilateral bearing, gear III, gear II, saw blade consist of the main motion driving-chain; Dc motor, gear I, gear II, saw blade consist of the assisted machining driving-chain.During the work of clockwork spring accumulation of energy driving-chain, the forward pulling wire grip, band pusher dog mono-directional overrun clutch is in engagement, band pusher dog mono-directional overrun clutch and gear V be forward simultaneously, the rotation of drive winder, click prevent from reversing the clockwork spring accumulation of energy, the at this moment inner ring of unilateral bearing counter-rotating is done with the outer ring disengagement of unilateral bearing and is surmounted motion, and motion no longer makes progress and transmits; During the work of main motion driving-chain, the pulling ratchet makes it to throw off with ratchet, under the driving of clockwork spring, power is delivered to unilateral bearing via gear V, gear IV, and its inner ring forward unilateral bearing is in engagement, the Internal and external cycle of unilateral bearing is forward rotation simultaneously, power is delivered to saw blade via meshing gear III, gear II, carries out cutting operation, is with the counter-rotating of pusher dog mono-directional overrun clutch this moment, do and surmount motion, realization and wire grip disconnection; During the work of assisted machining driving-chain, connect power supply of dc motor, the dc motor forward, power is delivered to saw blade via meshing gear I, gear II, carry out cutting operation, this moment reverses in the outer ring of unilateral bearing, does to surmount motion, assisted machining driving-chain and main motion driving-chain are thrown off, and avoid interfering.

The present invention realizes the transfer of energy by efficient gear drive, and gear structure is compact, and overall volume is little, and quality is light.Adopt the manpower outside to the clockwork spring accumulation of energy, compare high branch chain saw and save the energy, compare old-fashioned method and can reduce the amount of labour.Therefore this device can make the carrying out of reshaping of trees efficient work, safety, simultaneously with low cost, energy-saving and environmental protecting.
