Abstract
The invention discloses a lower cutting-off tool device of a combined harvester, and the lower cutting-off tool devic is characterized in that the front end of a bracket is provided with a lower cutting-off tool assembly; the rear end of the bracket is provided with an eccentric wheel actuating device; the eccentric wheel actuating device is composed of a sprocket wheel, a shaft and an eccentric wheel; the eccentric wheel actuating device converts the rotation of the eccentric wheel into the swinging of a swing arm; the swing arm swings to drive a movable blade in the lower cutting-off tool assembly to carry out alternating motion; and the middle of the bracket is connected with an advance-decline line. The lower cutting-off tool device of the combined harvester, provided by the invention has the advantages of scientific, reasonable, small and flexible structure and good use effect, the height of the lower cutting-off tool device can be regulated at will, and standing grain cutting height can be regulated manually without affecting rice spike cutting height; cut rice stalks orderly fall on the ground without affecting subsequent rice machine harvesting. The lower cutting-off tool device has a promotional value.
Description
Technical field
The present invention relates to combine, more specifically relate to a kind of combine lower cutter device.
Background technology
Grain header is the crop harvesting machinery of results cereal seed such as paddy and wheat and stalk, be known as combine at the beginning of the fifties, it is the harvesting that can once finish cereal, threshing, separation cane, remove operation such as assorted excess, directly obtains the harvest machinery of grain from the field.The small harvester lower cutter device is mainly used in the cane Huo He Zhuang that cuts standing grain, present small harvester lower cutter device and ceding of Taiwan synchronization lifting, can only regulate He Zhuang height according to the height of cane, height that can not the free adjustment lower cutter device, simultaneously, have the careless weak effect that gets rid of of lower cutter device now, cane disorderly falls, influence the harvesting of paddy rice, have much room for improvement for this reason.
Summary of the invention
Purpose of the present invention: a kind of combine lower cutter device is provided.
Technical scheme of the present invention is:
A kind of combine lower cutter device, it is characterized in that, front end at support is provided with cutter assembly down, rear end at support is provided with eccentric drive, eccentric drive is made up of sprocket wheel, axle, eccentric wheel, eccentric drive becomes eccentric rotation into the swing of swing arm, and the movable blades that the swing of swing arm drives in the cutter assembly down is reciprocating, support the middle part be connected with advance decline line.
Also be provided with level at the front end of described support and get rid of blade, the sawtooth that level is got rid of blade forward, on described cutter assembly down, be provided with and vertically get rid of blade, the sawtooth that vertically gets rid of blade makes progress, level is got rid of blade and do the swing arm campaign under the control of pull bar, and it is reciprocating with the movable blades in the following cutter assembly vertically to get rid of blade.
The described blade that vertically gets rid of is two, and the right and left of following cutter assembly is respectively established a slice and vertically got rid of blade, and it is a slice that level is got rid of blade, is located at the middle part of support front end.
Operation principle of the present invention: combine lower cutter device of the present invention is under the effect of chain drive-belt, the sprocket wheel rotation, sprocket wheel drives the eccentric wheel rotation, eccentric wheel drives the swing arm swing, movable blades under swing arm drives in the cutter assembly is reciprocating, it is also reciprocating with movable blades vertically to get rid of blade, simultaneously, swing arm drive level is got rid of blade and is swung, the rising of lower cutter device is tightened up advance decline line by tractor, the decline of lower cutter device is loosened advance decline line by tractor, the height regulated at will of lower cutter device, the height regulated at will of Ge He Zhuang.Level is got rid of the swing and vertical aggregate motion of getting rid of blade of blade, effectively realizes getting rid of grass.
Beneficial effect of the present invention: combine lower cutter device of the present invention, has scientific structure, reasonable, small and exquisite, flexible, result of use is good, the height regulated at will of lower cutter device is artificially regulated the height of Ge He Zhuang, artificially regulates the height of Ge He Zhuang, do not influence the height that cuts spike of rice, the paddy rice cane that cuts down falls down to the ground in order, and the paddy rice machine that does not influence is thereafter received, and has promotional value.
