Description
Technical field
The invention belongs to agricultural machinery technological field, particularly relate to the guide vane adjusting means of a kind of crushed stalk throwing returning machine.
Background technology
The substantial amounts of straw left in farmland after crop harvesting, peasant is typically directly to burn these straws before.But the way of this on-site incineration straw, not only waste abundant stalk resource, but also pollute environment, the most also leave many potential safety hazards.
Mechanized Straw chopping and returning is a kind of relatively effective straw processing method, and it is covered the straw scattering draught of chopping on earth's surface by Disintegrating knife chopping straw the most again, has not only processed straw but also add the organic matter of soil.In order to realize the also field of straw, the most it is changed on united reaper installation straw millstone by traditional manually shedding or tractor drives straw chopping and returning machine to shed straw.Straw is deposited in field in strip after the united reaper being mounted with straw millstone is pulverized, and the straw uneven the shedding in field can affect the growth with ensuing crop.Straw chopping and returning machine solves, relative to united reaper, the problem that straw is strip and piles up, but the problems such as the uniformity of straw scattering draught, fabric width and dispensing velocity do not obtain reasonable solution.
Fabric width and the uniformity is shed to the angle and then regulation adjusting guide vane as " the corn straw smashing chopper " of Patent No. ZL200710015135.5 is provided with guiding mechanism, but guide vane can not up and down, front and back can only regulate by rotating left and right adjusting, and the regulation of several guide vane angles is not to synchronize, so being limited to the regulation shedding the uniformity, fabric width and speed yet.In addition, also fixedly mount the straw both sides after guide vane makes pulverizing just like " the crushed stalk throwing method of a kind of full-feeding combine harvester and the device " of Patent No. ZL200910300350.9 in the straw exit of harvester to shed, to some extent solve straw to embark on journey the problem of lay, but the uniformity shed still fails well to ensure.
Summary of the invention
The invention provides the guide vane adjusting means of a kind of crushed stalk throwing returning machine, it is achieved that before and after guide vane, up and down, the adjusted in concert of left and right, thus regulate the uniformity of straw scattering draught, fabric width and speed.
