Abstract
The invention belongs to the field of agricultural machinery, and particularly relates to an improved man-powered lawn trimmer which comprises a handrail, a vehicle plate surface, wheels, a wheel shaft and a support. The lawn trimmer further comprises a speed-variable gear, a blade, grass fixing rake and a supporting rod. The handrail is fixed to the upper surface of the vehicle plate surface, the supporting rod is fixed to the lower surface of the vehicle plate surface, the speed-variable gear and the grass fixing rack are fixed to the supporting rod, the blade is installed on the speed-variable gear, the vehicle plate surface is fixed to the wheels through the support, and the two wheels are installed on the wheel shaft. The lawn trimmer solves the problem that in the prior art, a blade needs to rotate at high speed to cut grass, and has the advantages of efficiently cutting the grass when the blade rotates at low speed.
Description
Technical field
The invention belongs to agricultural mechanical field, be specifically related to a kind of Improvement type manpower lawn mower.
Background technology
Lawn mower also known as mower, weeder, grass mower etc., be a kind of for cutting the grass on a lawn, the machine tool of vegetation etc., have diesel engine and gasoline engine point.It is made up of parts such as cutterhead, engine, road wheel, running gear, blade, handrail, controls.Blade utilizes the High Rotation Speed output speed of engine greatly to improve, and saves the activity duration of weeding workman, decreases a large amount of human resources.In the country of Mechanization of animal husbandry high development, apply more extensive.
Existing lawn mower mainly relies on the fast rotational of blade, blade on High Rotation Speed cutterhead impacts cutting herbage, like this, just require that the rotary speed of blade must be very high, speed is low, and the ability of mowing just declines greatly, and grass can bend and blade is streaked from careless face, both cut continuous grass, destroy again the aesthetic property on lawn.
Summary of the invention
The object of the invention is to overcome in prior art must the problem that could mow of high-speed revolving blade.
For this reason, the invention provides a kind of Improvement type manpower lawn mower, comprise handrail, sweep face, wheel, axletree, support, also comprise change-speed gearing, blade, solid harrow and support bar.Sweep face upper surface fixed armrest, lower surface fixed support bar, change-speed gearing by bearing string on support bar, be positioned at above solid harrow, change-speed gearing and axletree transmission link, blade is arranged on change-speed gearing, sweep face is fixed on wheel by support, and two wheels are contained on axletree.
Described axletree is fixed wtih a helical gear, helical gear is meshed with change-speed gearing.
Described change-speed gearing comprises swash plate gear, hollow shaft coupling and cutterhead, and swash plate gear is connected by hollow shaft coupling with between cutterhead.
Described solid harrow there is a lot of rake teeth, the direction that rake teeth advances towards trimmer.
This Improvement type manpower lawn mower provided by the invention, comprise handrail, sweep face, wheel, axletree, support, also comprise change-speed gearing, blade, solid harrow and support bar, solid harrow is utilized to be lived by harrow, and then by blade cuts, can also realize mowing function when blade speed is unhappy, achieve the effect of cutting at a slow speed.
Below with reference to accompanying drawing, the present invention is described in further details.
Accompanying drawing explanation
Fig. 1 is the embodiment of the present invention 1 product structure schematic diagram.
Fig. 2 is the structural representation of change-speed gearing in the present invention.
Fig. 3 is the structural representation of solid harrow in the present invention.

Embodiment
Embodiment 1:
As shown in Figure 1, a kind of Improvement type manpower lawn mower, comprise handrail 1, sweep face 2, wheel 3, axletree 4, support 5, also comprise change-speed gearing 6, blade 7, solid harrow 8 and support bar 9, it is characterized in that: sweep face 2 upper surface fixed armrest 1, lower surface fixed support bar 9, change-speed gearing 6 by bearing string on support bar 9, be positioned at above solid harrow 8, change-speed gearing 6 and axletree 4 transmission link, blade 7 is arranged on change-speed gearing 6, and sweep face 2 is fixed on wheel 3 by support 5, and two wheels 3 are contained on axletree 4.
Described axletree 4 is fixed wtih a helical gear, helical gear is meshed with change-speed gearing 6.
In trimmer advance process, what first grass was encountered is solid harrow 8, Gu harrow 8 can by fixing in careless horizontal direction.Wheel 3 is advanced and is driven axletree 4 to rotate, and by the rotation of change-speed gearing 6 with knife section 7, the blade 7 of rotation carries out fly-cutting to the grass in solid harrow 8, completes the process of mowing.
Embodiment 2:
Described change-speed gearing 6 comprises swash plate gear 10, hollow shaft coupling 11 and cutterhead 12, is connected between swash plate gear 10 with cutterhead 12 by hollow shaft coupling 11.
Change-speed gearing 6 engages with the helical gear on axletree 4, rotation on helical gear vertical direction is become the rotation in change-speed gearing 6 horizontal direction, then by hollow shaft coupling 11, rotation is passed to cutterhead 12, because cutterhead 12 is different from change-speed gearing 6 radius, then achieve the function of speed change.The rotation of rotation with knife section 7 of change-speed gearing 6, realizes blade cuts function.
Embodiment 3:
Described solid harrow 8 there is a lot of rake teeth 13, the direction that rake teeth 13 advances towards trimmer.
The direction that rake teeth 13 advances towards trimmer, middle gap will be the position that grass stops at first, is fixed in the horizontal direction by grass by rake teeth 13, and doing so avoids trimmer grass when cutting can bend.
Described support bar 9 is semicircle in the position near axletree 4, avoids axletree 4.
In described Improvement type manpower lawn mower structure, except handrail 1 and sweep face 2, all Cheng Shuan is in tandem for all structures.
Be trimmer configuration two cover clipping devices, so not only maintain the stationarity of trimmer, and in pruning process twice stability appraisal, ensure that the completeness of pruning, improve the efficiency of equipment.
More than exemplifying is only illustrate of the present invention, does not form the restriction to protection scope of the present invention, everyly all belongs within protection scope of the present invention with the same or analogous design of the present invention.
