Abstract

Disclosed is a horticultural plant fence trimming device which is composed of a shell, a power mechanism and a cutting mechanism. A wrenching handle is arranged in the power mechanism, and straight teeth are arranged on the handle. The objective of efficient plant cutting and trimming can be achieved only by continuously wrenching the handle to drive a flywheel in the power mechanism through gear transmission to inertially and quickly rotate to drive a cutting wheel in the cutting mechanism to rotate at a high speed through belt transmission.

Description

A kind of gardening plant hedge clipping device

The present invention relates to a kind of gardening plant hedge pruning tool, especially a kind of gardening pruning tool that can semi-automatic use.

Along with the pay attention to day by day of people to the environmental greening problem, the prune picker is just in the urgent need to a kind of Labor-saving high-efficiency, automation vegetation pruning instrument cheaply, but at present, the still vegetation pruning instrument of shear formula that generally uses, not only labour intensity is large, and efficient is low, also hurts easily hand skin, and employing motor driven pruning tool, self heaviness, expensive, inconvenient maintenance.

In order to solve the deficiency of existing gardening plant pruning tool, the invention provides a kind of trimmer, can semi-automaticly use, can significantly improve pruning efficient.

The technical solution adopted in the present invention is: this trimmer is comprised of shell, actuating unit, cutting mechanism.One plate fixed handle is arranged in the actuating unit, on the handle with straight-tooth, as long as continuous plate fixed handle is by gear drive, drive the flywheel inertia fast rotational in the actuating unit, further pass through belt transmission, drive the scribing wheel High Rotation Speed in the cutting mechanism, thereby reach the purpose that high efficiency cutting is pruned plant.

The invention has the beneficial effects as follows, a kind of gardening pruning tool of semi-automatic efficient rate can be provided with low cost, have laborsaving, simple and reasonable advantage.

The invention will be further described below in conjunction with drawings and Examples.

Consult Fig. 1 to 9, it illustrates the trimmer of preferred embodiment of the present invention, and this trimmer is comprised of shell, actuating unit, cutting mechanism three major parts.Shell comprises: upper shell 2, lower house 28 form, and they connect by screw 1, and housing should adopt the plastic-injection moulding process to make.Actuating unit partly comprises: drive shaft mount A4 and drive shaft mount B22, they are screwed on the lower house 28.One gear shaft A5 is wherein arranged on the drive shaft mount A4, angular wheel A3 and belt pulley A6 are housed on the gear shaft A5.Drive shaft mount B22 is equipped with respectively gear shaft B19, gear shaft C20, three axle stamens of gear shaft D21 from the bottom up.One travelling gear A17 is housed on the gear shaft B19, a travelling gear B18 is housed on the gear shaft C20, the gear wheel engagement on the pinion on the travelling gear B18 and the travelling gear A17, they form the speed power train.Gear shaft D21 is equipped with axle sleeve 16 in two ends, and axle sleeve available copper material is made, and axle sleeve 16 is nested in the axis hole place of drive shaft mount, and one or three tooth parabola castle wheel 14 (structure as shown in Figure 9) flywheel 23 and belt pulley B24 are housed respectively on the gear shaft D21.The upper cover of belt pulley B24 has driving belt 7, and the other end of driving belt 7 is enclosed within on the belt pulley A6.Place, flywheel 23 one side axle center has circular groove, the aperture ratio axle stamen diameter of three tooth parabola castle wheels 14 is large, can not rotate with main shaft, its back double wedge is coaxial to be nested with in the interior circular groove of flywheel 23 (as shown in Figure 8), form the steel ball road, the wide end of an end is narrow in the steel ball road, and steel ball 15 is arranged in the steel ball road, the pinion of three tooth parabola castle wheels and the engagement of the gear wheel on the travelling gear B18, they also form the speed power train.Also be equipped with one at housing near the place of shaking hands and pull handle 26, there is a circular hole at the handle middle part, be hinged on the housing by Handle axis 27, cover has torsion spring 25 on the Handle axis, torsion spring 25 1 ends are stuck on the handle, the other end is stuck on the lower house 28, and the front end of handle is with the arc straight-tooth, the pinion of straight-tooth and travelling gear A17.Cutting mechanism partly is positioned at the front end of housing, comprising: angular wheel B8, break bar axle 9, bearing 10, rotating blade 11, hold-down nut 12, fixed blade 13 form.Angular wheel B8 bearing 10 and rotating blade 11 are housed respectively on the break bar axle 9, wherein angular wheel B8 is an angle of 90 degrees engagement with angular wheel A3, bearing 10 is ball bearing, it is nested in the lower house 28 front end circular grooves, on rotating blade 11 circumference with serration, be fixed on the bottom of break bar axle 9 by hold-down nut 12, front bottom end at lower house 28 also is equipped with a fixed blade 13, blade has sharp blade at the arc port towards rotating blade, fixed blade is upper, rotating blade is lower, and they are close to but can not contact.

When plate fixed handle 26, the straight-tooth band nutating gear A17 on the handle rotates, and travelling gear A17 band nutating gear B18 speed is rotated, and travelling gear B18 drives three tooth parabola castle wheels 14 again and does the speed rotation.Steel ball 16 in the steel ball road is snapped in the narrow end steel ball road, because frictional force, flywheel driven 23 is along with quick rotation, also quick rotation together of belt pulley B24 simultaneously, the transmission by belt 7 make also and then quick rotation of belt pulley A6, at this moment, because coaxial relation, angular wheel A3 is quick rotation also, drives angular wheel B8 towards another axle stamen direction rotation by the gear teeth, and at last order can be towards fixed blade 12 direction quick rotation to rotating blade 11.When handle 26 plates be at the end unclamp after, torsion spring 25 on the Handle axis 27 back rebounds owing to twisting force, make the handle reposition, corresponding band nutating gear A17, travelling gear B18, three tooth parabola castle wheels 14 rotate toward rightabout, steel ball 16 in the steel ball road returns in the wide end steel ball road, break away from flywheel 23 synchronous rotaries because zerofriction force makes three tooth parabola castle wheels, and reach the purpose of clutch.But flywheel 23 since effect of inertia still with belt pulley B24 quick rotation, the continuous like this handle 26 of back and forth pulling, constantly accelerate, order is to rotating blade 11 towards fixed blade 12 direction High Rotation Speeds at last, because the serration on rotating blade 11 circumference is at a high speed towards the edge direction relative motion of fixed blade, thereby reach the purpose of cutting.

Figure 10,11 illustrates the trimmer of the second embodiment, the improvement of this embodiment is mainly in the cutting mechanism part, actuating unit partly just increases by one group of travelling gear makes the dynamic rotation direction of its generation and the opposite direction of top embodiment, this do not explain in detail see also above embodiment.The cutting mechanism of present embodiment partly is equipped with two groups of rotary cutting bodies, and two rotating blades of its bottom are close to up and down overlapping being installed in separately on two break bar axles, and in the time of cutting, they are High Rotation Speed relatively, reaches the effect of cutting.
