Description
Affiliated technical field: the utility model relates to the machinery that a kind of 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, exist noise big, problems such as environmental pollution is serious, place in office and study, this grass mower that needs power engine just seems and is not to be popular that the United Nations is annual for this reason uses more than 3,000 sheep for cutting grass with staying Genevangenevese office.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 grass is discharged, and can bring strong vibrations to the staff during operation, causes operation uncomfortable, and is also higher to the security requirement of complete machine.Simultaneously, owing to be equipped with power set, make its price expensive, maintenance, maintenance cost are also higher.
Summary of the invention: the purpose of this utility model is to overcome the problem that noise was big, environmental pollution is serious when the lawn grass mower that has power engine now was used, a kind of environment-friendly type hand-push type lawn grass mower is provided, utilize manpower to promote grass mower walking power and realize cutting the grass action, cut grass as blade movement power.
The technical solution of the utility model is: environment-friendly type hand-push type lawn grass mower is by transfer bar mechanism, the frame mechanism that band seesaws and takes turns, cover in the casing on the frame, and the speed increasing mechanism, movement conversion mechanism and the executing agency that are loaded on the frame form, speed increasing mechanism is a gear drive, movement conversion mechanism is the cam lever body, and cutting careless executing agency is slide block guide rail mechanism.Use for convenience, the cutting-height governor motion also is housed on the frame; Transfer bar mechanism can be foldable structure or stretching structure, and by push rod, telescoping tube, folding fastening wing nut is formed.
Gear drive is by the gear wheel (2) that is installed on the hind axle, and the bearing bracket (19) that is loaded on the frame upward and with the gear shaft (3) of pinion is formed; Module is 2, and the gearratio of large and small gear is 2～5.By the speedup of gear drive, the careless efficient of cutting of grass mower is improved.
The cam lever body is by installation (can realize by key or screw thread) cam on left end face (4), right side cam (15) on gear shaft, and installation (can pass through T type groove and screw) left and right sides driving lever (5) on slide block (6) is formed.The double wedge of edge cam is 6～10 teeth (selecting as required), left and right sides edge cam interlace a tooth, lean against and be fixed on privately on the gear shaft (3), contact on the double wedge flank of tooth of cam with the left and right sides driving lever (5) on being installed in slide block (6), form movement conversion mechanism, finish the conversion of spatial movement, with the rotational transform of cam be slide block about move back and forth; Simultaneously,, further improved the operating efficiency of grass mower, and regulated for the height of designed cutting-height governor motion and to provide convenience by the speedup between the cam lever body.
Slide block guide rail mechanism by slide block (6), guide rail (7), be fixed on the movable blades (8) on the slide block, the fixed blade (9) that is fixed on the guide rail is formed, guide rail is fixed on the frame, by the dovetail groove constrained motion, slide block and guide rail can only be done relatively reciprocating motion between slide block and the guide rail; Movable blades and fixed blade can be fixed on slide block and the guide rail with sunk screw respectively.Relative reciprocatingly sliding between slide block and the guide rail makes movable blades fixed thereon and fixed blade relative motion, thus finish grass mower cut the grass action.
Cutting-height governor motion (16) is by the hangers on the guide rail that is fixed on slide block guide rail mechanism (18), be fixed on the bearing bracket (19) on the frame, wing nut (20) is formed, have on the bearing bracket stand and with holesly (can establish a plurality of circular counter bore, at regular intervals between per two holes) guide groove, hangers is set in the counterbore of bearing bracket stand upper rail, and is fixed by wing nut.The hangers that will be connected with cutter frame mechanism (slide block guide rail mechanism) is gone up along the guide groove on the bearing bracket stand (in the counterbore on guide groove) and is moved, and utilizes align member (wing nut) that hangers is locked at the position of different counterbores, has promptly finished the adjusting of blade cutting-height.The adjusting of height causes the contact point on the double wedge flank of tooth of driving lever and edge cam to change, go up at various height, contact point moves along the radial direction of edge cam double wedge, the track of contact point appears on the different radiuses, the movement velocity of driving lever is changed thereupon, and the speed of movable blades also changes thereupon when promptly cutting grass.
The utility model promotes the grass mower motion by manpower, realizes cutting the grass action, and having solved traditional lawn grass mower needs power engine to drive the problem that just can make grass mower work.Designed environment-friendly type hand-push type lawn shear grass prow will pass manpower by a Force transmission parts (push rod) earlier, in order to allow the operator under a normal speed of travel, operate, the power that passes continues to transmit by a speed increasing mechanism, because of the direction of relative movement of blade that carry out to prune the grass action and the people direction of advancing vertical, switching mechanism is delivered to the execution member to the motion need that pass over through the front speed increasing mechanism through one-level again, just can finish and cut the grass action.
The beneficial effects of the utility model are: need not power engine, adopt manpower to drive, noise is little, pollution-free, makes the user can not have influence on people's working and learning on every side when cutting careless operation, simultaneously energy savings.In addition, this grass mower compact conformation, volume is little, and is in light weight, easy to use flexible, and the grass of cutting that is fit to the small size lawn is handled; Its service behaviour is good, can finish effectively and cut grass work, cuts the height of grass and can classification regulate.The push rod of this grass mower can also the folding retractable folding and unfolding, and the personnel that are suitable for different heights use, and occupation space when having reduced grass mower greatly and not working, and is convenient to deposit.
