Abstract

The utility model relates to a machine for manually mowing lawns, in particular to a hand-push type lawn mower, which belongs to the technical field of garden machines. A pushrod framework of the lawn mower is equipped with wheels, wheel shafts are equipped with pinions, the pushrod framework is equipped with gearwheels meshed with the pinions, gearwheels shafts are equipped with roller cutters, the pushrod framework is equipped with parallel blades with parallel gaps, and the parallel gaps are axially parallel to the roller cutters. When manually pushing the pushrod of the lawnmower, the wheels rotate to drive the pinions and the gearwheels, and then the roller cutters and the parallel blades are in relative movement to complete lawn mowing actions. The utility model has simple structure, small volume, light weight and low cost, is driven manually, and saves energy.

Description

Hand-push type lawn grass mower

Technical field

The utility model relates to a kind of hand-push type lawn grass mower, is the machinery that manpower cuts the grass on a lawn, and belongs to the graden machine technical field.

Background technology

Lawn grass mower on the market needs power engine mostly at present, and noise is big, and environment is had pollution.Power engine lawn grass mower mainly is to rely on the high speed rotating of blade that grass is cut off, and by swirling eddy broken grass is discharged.Can bring strong vibrations to the staff during operation, cause operation uncomfortable, also higher to the security requirement of complete machine.In addition, have the grass mower structure relative complex of power set, thereby price is expensive, maintains, maintenance cost is also higher.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of hand-push type lawn grass mower, and it is simple in structure, is driven by manpower, and volume is little, and is in light weight, and cost is low, energy savings.

Solving the scheme that technical problem of the present utility model adopts is: on the push rod frame wheel is housed, adorn pinion on the axletree, the gear wheel of dress and pinion is equipped with hobboing cutter on the push rod frame on the Large Gear Shaft During, and dress and cutter shaft are to the parallel blade that leaves parallel clearance on the push rod frame.

The concrete technical scheme of this device also comprises: the V-shaped arrangement of a series of hobboing cutter cutting edge on the cutter shaft; The gearratio of pinion and gear wheel is 3～5.The installing rack of parallel blade is hinged on the push rod frame, and this installing rack is pressing the adjustment spring and the adjustment wing nut is housed.Be positioned at parallel blade and hobboing cutter below on the push rod frame, be provided with the refuse bag hook, above refuse bag hangs over.

When cutting grass, manpower promotes the push rod frame and turns a wheel, pinion on the wheel hub also rotates thereupon simultaneously, rotation is passed to gear wheel, the hobboing cutter that links to each other with Large Gear Shaft During is rotated, so hobboing cutter and parallel blade generation relative motion produce shearing force, cut off long grass, finish and cut the grass action.The grass of being cut off produces a thrust under the rotation of hobboing cutter, the broken grass that nature will be wiped out pushes in the refuse bag of push rod frame below suspension.

The beneficial effects of the utility model are: when being used for the meadow and cutting careless operation, need not power, adopt manpower to promote little, the pollution-free and energy savings of noise.This grass mower compact conformation, volume is little, and is in light weight, and easy to use cost is extremely low flexibly, and is convenient to maintenance.The grass of cutting that is fit to the small size lawn is handled.

Embodiment

Referring to Fig. 1～3, wheel 2 is housed on the push rod frame 1, adorn pinion 3 on the axletree, dress and the gear wheel 4 that pinion 3 meshes are equipped with hobboing cutter 5 on the push rod frame 1 on the Large Gear Shaft During, and dress and cutter shaft are to the parallel blade 6 that leaves parallel clearance on the push rod frame 1.See Fig. 2 for details, the V-shaped arrangement of the cutting edge of hobboing cutter 5, this layout combines with the angle blade of parallel blade 6, can obtain shear effect preferably; Pinion 3 adopts 3～5 with the gearratio of gear wheel 4, and the shearing force of grass mower is increased, and improves and cuts careless efficient.The installing rack of parallel blade is hinged on the push rod frame 1 by blade connecting rod 10, the below of this installing rack is pressing adjustment spring 7 and is being equipped with adjusts wing nut 8, rotate wing nut 8 and just can realize the fine setting in hobboing cutter 5 and parallel blade 6 gaps, reach the pressure that changes between hobboing cutter 5 and the parallel blade 6, realize best shear effect.Be positioned at parallel blade and hobboing cutter below on the push rod frame 1, be provided with refuse bag hook 14, above refuse bag 15 is hung over.After using a period of time,, can also unload hobboing cutter 5 and parallel blade 6, on a plane whetstone, sharpen the edge of a knife, reinstall the back and use if can't cut off little grass fully.

Claims
