Abstract

The utility model provides a hand-operated manpower wheat cutter. The wheat cutter is composed of members such as a push rod, wheels, a shifting rack, a fixed cutter, a rotary movable cutter, a large cone gear, a small cone gear, etc. The push rod is connected with the shafts of the wheels via a connecting rack, the inner shafts of the wheels are fixed with the large cone gear and the small cone gear which are engaged with each other for converting the running power of the wheels into the rotating force of the movable cutter, and thus the shearing force of the rotary movable cutter and the fixed cutter is formed in order to obtain the aim of harvesting. The wheat cutter has easy and flexible use, easy maintenance, economy and durability, harvesting efficiency is increased, labor intensity is relieved for farmers, and the hand-operated manpower wheat cutter is suitable for the production of general small mechanical factories.

Description

Hand-operated manpower wheat cutter

The utility model belongs to the agricultural machinery class, especially a kind of manpower crop harvester that is suitable for family's use.

Follow so far, the vast rural households of China getting wheat, seeding corn and other crops, what still adopt is that the reaping hook that work efficiency is low, labour intensity is big is that instrument gathers in; Large-scale grain header volume is big, oil consumption is many, cost is high, is not suitable for the small pieces contract cultivate land.How wide farmers is freed from onerous toil, become one of outstanding feature of social development, technological progress.

The purpose of this utility model be to provide a kind of little at current family contracting land area, the high-effective and labour-saving of characteristics such as scattered, easy to use, economical and practical manual hand reaper distribute.

For achieving the above object, the technical scheme that the utility model is taked is: this wheat harvester is made up of parts such as push rod, wheel, group frame, stationary knife, rotation moving knife, big small conical gears, push rod is connected with the axle of wheel by link, and big small conical gear is fixed on the inboard of wheel; The periphery of small conical gear is fixed with the knife rest sleeve pipe, dialling the centre bore that the frame dead lever passes stationary knife is enclosed within the knife rest sleeve pipe, fixedly connected with small conical gear (3), one end of stationary knife also passes through the stationary knife strut fixation on the stationary knife dead lever, and the central point of rotation moving knife is fixedly connected on to be dialled on the frame dead lever; Dial the top of chord position, can in harvesting, crop be dialled to a side in stationary knife and rotation moving knife; Big small conical gear is meshed, and the onward impulse of wheel is converted into the revolving force of moving knife, and then forms the power of cutting of cutting of rotary power and stationary knife, realizes the harvesting purpose.

The manual hand reaper that is manufactured and designed by such scheme has following characteristics: simple in structure, easy to maintenance, saving of labor, laborsaving, cost is low, volume is little, body is light, easy to use, flexible, can improve harvesting efficiency, alleviate peasant household's physical labor intensity, extensive market prospects is arranged, be suitable for the little factory of general machined and practice midwifery.
