Description
Technical field
The utility model belongs to the graden machine technical field, relates in particular to the body-building environment-friendly type lawn grass mower that a kind of manpower cuts the grass on a lawn.
Background technology
Entered since 21 century, environmental protection and body-building become the topic of a hot topic gradually.With regard to mechanical industry, environmental protection machinery and fitness machine are also more and more welcome, but the cost costliness mostly of environmental protection machinery in the market do not popularized, fitness machine also because of price higher and not too practical do not have universal.
The pruning on lawn has two kinds of forms at present, and a kind of is to adopt manpower to utilize scissors to prune, and another kind then is to adopt the diesel oil motor to drive motor to prune.The former labour intensity is big, and owing to be manually to prune poor effect according to range estimation; Though the effect that the latter prunes is better, it needs the extra energy, not only consumes greatly, and environment is also had certain pollution.This dual mode does not all have to combine with body-building simultaneously, only is a kind of pure work.
Summary of the invention
The purpose of this utility model is exactly serious, the great problem of noise of environmental pollution in order to solve existing lawn grass mower and to use, provide a kind of have simple in structure, easy to use, the operator can reach the body-building environment-friendly type lawn grass mower of advantages such as body-building effect when cutting grass.
For achieving the above object, the utility model adopts following technical scheme:
A kind of body-building environment-friendly type lawn grass mower, it comprises foot-operated car body, install and cut careless device at the front-wheel place of car body, front-wheel with cut careless device and be connected with the foot pedal apparatus of car body.
Described car body comprises wheel stand, and back vent is installed at the wheel stand rear portion, and trailing wheel is installed on the back vent; The anterior front fork of installing of wheel stand is installed a front axle on the front fork, a front-wheel is respectively installed at the front axle two ends, is provided with front-wheel drive and is connected with foot pedal apparatus on front axle, cuts careless device and also is connected with front axle; Wheel stand also is connected with knee simultaneously, the terminal mounting knob of knee, and handle matches with the vehicle seat position on the wheel stand.
Described knee is provided with puggaree.
Described foot pedal apparatus is a sprocket wheel, and pedal is installed on the sprocket wheel, and sprocket wheel is connected with front-wheel drive by chain.
Describedly cut careless device and comprise gear drive, it cooperates with the cam follower device, and cam follower is then cut careless device with slide block guide rail and is connected, and slide block guide rail is cut careless device side and is provided with adjusting device.
Described loading drive gear is changed to the gear wheel that is installed on the front axle; Described cam follower device is a camshaft, and camshaft is provided with and the gear wheel pinion in mesh, and modulus is 2, and the gearratio of big pinion is 2.5, goes back the installation end face cam on camshaft, and edge cam is then cut careless device with slide block guide rail and is connected.
Described slide block guide rail is cut careless device and is comprised fixed blade and movable blades, fixed blade is connected with adjusting device, movable blades is connected with slide block, slide block is arranged in the guide rail of fixed blade, on slide block, also be provided with at least one dog screw, movable blades also with about two push rods be connected, push rod cooperates with edge cam.
Described adjusting device comprises a pair of gripper shoe, and double-screw bolt respectively is installed on it, and fixed blade is threaded with double-screw bolt.
Body-building environment-friendly type of the present utility model lawn grass mower by car body, cut careless device etc. and form.The rear-axle steering amplitude is less, turns to flexibly, be applicable to middle-size and small-size lawn, in order to adapt to various lawns, has also designed the adjusting that adjusting device realizes cutting-height.
The utility model wheel stand connects front and back wheel, hinge wheel, pedal, vehicle seat etc. is housed, main support people's body weight on the wheel stand.
Trailing wheel is installed on the back vent, and wheel stand also is connected with knee, and terminal on the knee is that handlebar, middle part are puggaree.Back wheel diameter can be 50 centimetres, and front and back wheel all has rubber tyre, can reduce the pressure to the lawn, plays the effect on protection lawn.
Gear drive is made up of the pinion that is installed in the gear wheel on the front axle and be installed on the camshaft, and modulus is 2, the gearratio of big pinion can be chosen in the scope of 2-5 according to actual conditions.The gear drive speedup makes cuts careless efficient and is improved.
The cam follower device comprises the edge cam and the pinion that are installed on the camshaft, and pinion cooperates with gear wheel, can realize the adjustment of speed.
Slide block guide rail cut careless device by fixed blade, movable blades, be installed in the slide block on the movable blades and be located at guide rail on the fixed blade etc. and form.Guide Rail Design is on the fixed blade, and slide block is subjected to the constraint of guide rail, can only do linear reciprocating motion in guide rail; Slide block is limited on the movable blades with dog screw, and the reciprocating motion of slide block between guide rail makes between movable blades and the fixed blade and produce relative motion, thereby realizes cutting the grass action.Movable blades is connected with left and right sides push rod, and as required, the projection of edge cam can be formed by 6 to 8, is installed on the camshaft with key.Convex surface contacts with the steamboat on the push rod of the left and right sides is surperficial, forms movement conversion mechanism, realizes the rotation of cam is converted to the reciprocating imagination in the left and right sides of blade.
The cutting-height adjusting device by left and right sides gripper shoe, be installed in the double-screw bolt on the gripper shoe and the fixed blade that is threaded is formed.When cutting-height need be regulated, if with about double-screw bolt alternately turn, make the stressed as far as possible balance of both sides fixed blade, in order to avoid blade is stuck, so just can realize the step-less adjustment of cutting-height.The adjusting of height changes the steamboat on the push rod and the contact point of cam, contact point moves along the radial direction of edge cam, the track of contact point appears on the different radiuses, though the height adjustable range at 20mm between the 120mm, but the scope of its change in radius is also little, the speed of service of push rod does not change thereupon, and the moving speed of blade does not change yet when cutting grass.
This product promotes the grass mower motion by people's pedal sprocket wheel, realizes cutting the grass action, is different from the situation of traditional grass mower work that only just can realize under the situation that power engine drives.Designed body-building environment-friendly type lawn shear grass prow will be realized front-wheel drive by the pedal sprocket wheel earlier, by the gear wheel on the front axle pinion is passed in motion again, pass to cam follower mechanism then, utilize cam follower mechanism that circular motion is converted to the reciprocating motion of blade, finish and cut the grass action.
The beneficial effect of this practical grass mower is: need not power engine, the employing manpower drives, pollution-free, noise is little, when cutting careless operation, can not have influence on people's working and learning on every side, reach the purpose of energy savings simultaneously yet, adopt durable cast aluminium frame and structural member in addition, can weight reduction, the characteristics of have Never-rusty, never curling.This grass mower compact conformation in addition, volume is little, and is in light weight, flexible and convenient to use, is fit to middle-size and small-size lawn and uses, in particular for the lawn in places such as study office.This grass mower combines environmental protection and body-building, makes it have dual-use function, allows the operator obtain body-building when cutting grass, makes its tool environmental protection, body-building and practical characteristics.
