Abstract

A hand propelled miniature rice harvester comprises a loading truck (1), an engine (2), a generator (3), a threshing device (4), and a grain-reaping device (5), which is characterized in that the threshing device (4) is provided with a grain-combing wheel (6), the grain-reaping device (5) is provided with a grain-inclining oblique plane (7). The utility model can respectively realize threshing and stalk-reaping, and force rice plants fall to one side, and is applied to the mountainous areas in the south.

Description

Hand-push type small-sized rice grain header

Technical field

The utility model relates to a kind of hand-push type small-sized rice grain header, especially the rice harvester that uses at the terraced fields of southern mountain knob.

Background technology

At present, the primary structure of the rice harvester that generally use in known rural area is: working portion is the round roller that has the steel wire tooth, on every side and above the backplate that prevents that the grain of rice from disorderly flying is arranged, the top backplate has very wide opening, the people can hold paddy rice threshing on the round roller that rotates of cutting off with hand, the thresher operating efficiency of this open type is low, and peasant's labour intensity is big, and it is dangerous to work; Large-scale rice/wheat combine has very high operating efficiency, but its volume is big, and weight is big, the energy consumption height, and only be adapted at the flat area use, be not suitable for southern mountain and hill area and use.

Summary of the invention

In order to overcome the above-mentioned deficiency of existing rice harvester, the utility model provides a kind of and realizes shelling respectively and cut rice, makes the rice strain predominate, and is fit to the small-sized semi-automatic rice harvester that use in southern mountain and hill area.

The technical scheme that its technical problem that solves the utility model adopts is: the utility model is made up of load wagon, engine, generator, threshing device, rice cutter and hand-pushing handle, and engine and generator are fixed on the board foot rest that loads the compartment afterbody; Threshing device is fixed on cuff in the lifting groove of load wagon front end, and height is adjustable; Rice cutter is fixed on the load wagon front end base plate; Engine, generator, threshing device, rice cutter are formed the closed-loop path, and switch is located on the hand-pushing handle.Rice cutter sawtooth and threshing device circle roller keeps a determining deviation in the vertical projection direction, and the circle roller is preceding, sawtooth after, to realize cutting rice behind the first shelling.Wherein:

Threshing device is made up of the round roller, rice combing wheel, power wheel, motor and the backplate that have the steel wire tooth, rice combing wheel has fixed rotating shaft, rotating shaft is socketed on the backplate after passing gear, motor is installed in power wheel inside, the two ends of circle roller, power wheel and rice combing wheel are gear structure, and each gear is engaged with each other; Rice combing wheel is made of gear that is fixed on the rotating shaft two ends and the comb rice bar that is connected on the gear; Power wheel is fixed on motor center rotating shaft two ends, and behind the connection power supply, under the effect of two ends engaging tooth wheels, rice combing wheel and circle roller move;

Rice cutter is provided with the rice strain and topples over the inclined-plane, and front end is provided with sawtooth, and its interior and operation principle are with electronic hair cutter.Link to each other with base plate by the metal hinge, the side drift angle has an arc hole slot, one moving fulcrum is arranged therebetween, one end of moving fulcrum is installed in the hole slot, with spring opposite direction tractive, rice cutter can 90 ° of free folding exhibitions under the acting in conjunction of metal hinge, moving fulcrum and arc hole slot, are erected at when amounting on the platform floor, and the rice cutter bottom surface is parallel with platform floor during expansion.

The beneficial effects of the utility model are: volume is small and exquisite, and quality is light, and is simple in structure, and low price uses operation extremely easy, can realize shelling respectively and cut rice, and can realize that the rice strain is predominate, is fit to southern mountain and hill area and uses.
