Description
Technical field
The utility model belongs to agriculture and forestry machinery technical field, relates to the drive mechanism on a kind of maize-straw harvestor.
Background technology
Maize-straw harvestor is ripe at corn or approaches when ripe, according to agriculture requirement, completes the operation farm machinery to corn straw harvesting with mechanical.For new exploitation of energy resources with alleviate friend's peasant labour intensity and a kind of novel agricultural machinery researched and developed, the little four-wheel in a kind of cheap applicable rural area is universal, supporting agricultural machinery that just can harvesting corn stalk.It has shortened work cycle of friend peasant, allows people free from heavy manual labor.
In the Northeast of China, as the northeast in Jilin, the western part in Heilungkiang etc., land resources is of great rarity, corn is often planted on hillside, and ground flat degree is poor, because existing corn picker is generally all for open ground is designed, corn on hillside has to be completed by manpower the harvesting of stalk, corn on hillside is being plucked corn after receipts, the harvesting of stalk becomes very trouble, the collection of stalk and transport are comparatively required great effort time-consuming, along with the propelling of agricultural mechanization, people are to maize-straw harvestor, the corn picker that is particularly applicable to non-open area is more and more thirsted for.
This drive mechanism is a part for grain header, is mainly to provide drive mechanism that a kind of climbing capacity is strong to changing grain header, makes this grain header be suitable for the straw harvesting on uneven terrain.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist for existing technology, and the drive mechanism on a kind of maize-straw harvestor is provided, and technical problem to be solved in the utility model is how to improve the climbing capacity of grain header.
The purpose of this utility model can realize by following technical proposal: the drive mechanism on a kind of maize-straw harvestor, grain header comprises a car body, it is characterized in that, on described car body, be fixedly installed an engine and two chopping disks, described engine is connected with described chopping disk, described car body comprises first half vehicle frame and later half vehicle frame, between described first half vehicle frame and later half vehicle frame, be hinged, described engine is arranged on first half vehicle frame, between described first half vehicle frame and later half vehicle frame, be provided with some adjusting cylinders, the cylinder body of described adjusting cylinders is fixedly connected with later half vehicle frame, the piston rod of described adjusting cylinders and described first half vehicle frame are hinged.
Adjusting cylinders mainly contains two effects, and one, in when climbing, shorten distance between grain header front and back wheel, increase the distance between vehicle bottom and ground, increase the thrust between front and back wheel and ground, improve the climbing capacity of grain header; Wherein, driven pulley is arranged on the position near later half vehicle frame rear end, and between first half vehicle frame and later half vehicle frame, in the time that hinge swings, the rear end of later half vehicle frame has certain terrain clearance, and first half vehicle frame itself just has a radian being upturned, the trafficability characteristic while harvesting to improve grain header; Two, straw harvesting is tightened after bundled and is placed on later half vehicle frame, proceeds on smooth road surface when full when harvesting is airborne, and adjusting cylinders shrinks later half vehicle frame is tilted, and stalk is unloaded.
In drive mechanism on above-mentioned a kind of maize-straw harvestor, on described first half vehicle frame, be provided with the front axle being connected with engine, the two ends of described front axle are provided with driving wheel, on described later half vehicle frame, be provided with hind axle, the middle part of described hind axle is provided with a hinge, between described hinge and later half vehicle frame, be provided with anti-skidding cylinder, the cylinder body of described anti-skidding cylinder is fixedly connected with described later half vehicle frame, and the piston rod of described anti-skidding cylinder and described hinge are hinged.This grain header is front driving type, due to the lighter weight of stalk own, grain header is without too large bearing capacity, front driving type grain header has better climbing capacity, and being provided with a hinge at the middle part of hind axle, this hinge can be controlled by anti-skidding cylinder, makes the two ends bending of hind axle, driven pulley can be tightly compression ground, thereby prevent grain header and concavo-convex ground and skid.
