Description

Trolley type portable type combine

The utility model relates to a kind of grain header, but particularly relates to a kind of results of double as dolly use and the combine of transportation dual-purpose.

Being used in the past gather in the crops the combine of crops such as paddy rice and wheat the huge heaviness of the bodily form, involve great expense, it can only use on the flat-bottomed land and the farm in large tracts of land farmland, is not suitable for small size farmland and self-employed farmer's use that mountain area and hilly country etc. disperse.In recent years, these those skilled in the art have made a series of improvement to the old-fashioned combine of huge heaviness, but its volume is still bigger, costs an arm and a leg, and, existing combine only is used to gather in the crops crops, can not use as haulage vehicle, its purposes is single, in the time of slack season, can only leave unused, cause the device resource waste.In addition, the blade function that the cutter sweep of existing combine uses is preferably rotary blade, and speed is fast though it has, power is than characteristics such as height, but the driving mechanism complexity of this rotary blade, the installation difficulty height, cost is higher, and has when using and Lou cut and fall the rice phenomenon.

The purpose of this utility model is that existing combine is made improvements, and provides a kind of and be suitable for that the price that small size farmland and self-employed farmer use is low, the bodily form is little, can be used for the portable type combine of transportation.

Trolley type portable type combine of the present utility model mainly comprises parts such as frame, power and controlling organization, running gear, cutter sweep, conveying plant, threshing and cereal separator, and the connecting relation between the each several part is similar to existing general grain header; This grain header complete machine overall width is 0.8～1.5m, and total height is 1.5～1.8m, and total length is 1.8～2.5m; Its cutter sweep is reciprocal shearing structure, and the mode of regulating height with liftable by pole is set in the loop bar of frame front end; The frame postmedian is provided with railway carriage, and is provided with the seat; Above conveying mechanism, be respectively equipped with cover cap with the cutter sweep front upper place.

The utility model compact conformation, the bodily form is little, cost is low, owing to be provided with railway carriage, seat and cover cap, machine shape is little vehicle, both can be used for agricultural things such as harvesting rice and wheat, but the double as dolly uses again.Therefore, the utility model grain header is particularly suitable for small size farmlands such as mountain area, hilly country and uses, and is particularly suitable for the self-employed farmer and uses, and is used to gather in the crops crops during the busy farming season, is used for passenger and freight transportation during slack season, realizes a tractor serves several purposes.

The cutter sweep of the utility model grain header adopts reciprocal shearing structure, uses dentation sword rectangular blade, has that volume is little, simple in structure, installation and easy to maintenance a, advantage such as cost is low, and rarer leakage is cut and fallen the rice phenomenon during harvesting.

Below in conjunction with accompanying drawing the utility model is elaborated.
