Background technology
Be dispersed with a large amount of terraced fields in the hilly country, the southeast of China, terraced fields are generally less than 30 ° hills in the gradient is opened up wasteland, meeting China some areas can the few needs of acreage under cultivation, and because landform is special, agricultural modernization machinery is difficult to use at terraced fields.
Paddy field generally all needs to carry out making beating and smooth, along with popularizing of agricultural modernization machinery, smooth paddy field can utilize planisher to carry out, but, in terraced fields, the people of rice cultivation commonly use comparatively original manpower shoulder and draw the smooth paddy field of mode, namely rope is fixed at the timber two ends for smooth paddy field, timber moves forward by pulling rope by labourer, thus realize the object in smooth paddy field, in addition, in order to ensure timber not deflection, timber rear also needs a people to correct in time timber usually, and assist the former to promote timber, this level land mode is comparatively original, inefficiency, labour intensity is large, and work inclement condition is carried out in paddy field.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of pedal flattening device.
The present invention solves its technical problem and realizes by the following technical solutions:
A kind of pedal flattening device, comprise main shaft, described main shaft both sides are all overlapped and are had running gear, main shaft two ends are all fixed with drive unit, are fixed with arm-tie in the middle part of main shaft, and the other end of described arm-tie is connected with and is bulldozed block, the described lower surface being bulldozed block is cambered surface, to be bulldozed block to slide in paddy field, the middle part of described main shaft is also fixed with arm-rest frame, and the other end of described arm-rest frame is fixed with handrail.
Described running gear comprises axle sleeve, and described axle sleeve the inner is fixed with road wheel, and axle sleeve outer end is fixed with driven gear.
Described drive unit comprises connecting plate, and one end of described connecting plate is fixed on main shaft, and the other end of connecting plate is connected with crank, the inner side of described crank is fixed with driving gear, the two ends of crank are equipped with pedal, and operating personnel, by rotating pedal, make crank rotate in one end of connecting plate.Driving gear on crank drives driven gear to rotate, and because driven gear and road wheel are all connected on axle sleeve, road wheel rotates under the drive of driven gear, and the main shaft promoted in axle sleeve advances.
Described road wheel adopts bonding jumper layout to make, and the side of road wheel is welded with metal coil bonding jumper being played to booster action.
The gearratio of described driving gear and driven gear is not less than 3:1, and the gearratio of driving gear and driven gear is too small, and driving gear will be caused to rotate difficulty, and the moment of driving gear increases, and retardation efficiency is low.
Described driven gear is not less than 1:3 with the diameter ratio of road wheel, and the diameter of driven gear and road wheel, than too small, will increase driven gear rotary resistance, increases driving gear and rotates difficulty, also increase connecting plate Moment simultaneously, connecting plate is easily fractureed.
The distance of described metal coil and road wheel outermost end is not less than 10cm, ensures that road wheel has enough length to nip in paddy field, increases the frictional force in road wheel and paddy field, skids when preventing metal coil from directly rolling in paddy field.
The invention has the beneficial effects as follows: the present invention adopts foot pedal type driving mechanism, instead of employing manually to pull and be bulldozed block and carry out smooth paddy field, reduce labour intensity, improve work state, people are departed from from paddy field out, avoid the harsh state that people's long period of soaking carries out highly intensive labour in paddy field, gearratio setting between driving gear and driven gear is suitable, the diameter Relationship of driven gear and road wheel sets rationally, the moment needed for driven gear rotation can be reduced, person easy to use promotes road wheel and advances, connecting plate is fixed on the two ends of main shaft, for crank provides support power, space is left between driven gear and road wheel, avoid road wheel and crank to produce to interfere, level land block is positioned at the rear of main shaft, counterweight effect is play to main shaft, prevent main axis and drive unit upset.
