The utility model discloses set up double fan in harvester shale shaker front side, simple structure, with low costs, occupation space is little. When cleaning cereal, come from the blowing to the buckled plate of vice fan, the anterior wind speed of buckled plate is big, and distinguished and admirable volume is big, cleans effectually. Coming from the blowing to chaffer screen and lower sieve of main air blower simultaneously, can guaranteeing that cereal effectively separates, the loss of seed grain is little, cleans efficiently.
Description
Technical field
This utility model relates to a kind of cleaning device of combined harvester, especially a kind of cleans effective cleaning device of combined harvester, belongs to agricultural machinery technological field.
Background technology
Along with united reaper is to high speed, efficient, high-performance direction development, ability of cleaning has become the key factor of restriction united reaper development. Existing longitudinal axial flow cleaning device of combined harvester includes vibrosieve and centrifugal blower, when cleaning corn, major part material drops on vibrosieve corrugated plating, along with vibrosieve front-rear reciprocation movement, plus the wind-force effect of centrifugal blower, material is easily separated is cleaned by vibrosieve corrugated plating, top sieve and lower sieve. But limited etc. by combine width and centrifugal blower size and affected, the centrifugal blower left and right sides produces obvious air draught, and corrugated plating front portion wind speed is little, wind flow is little, cause that corn, straw blockage are in corrugated plating front end, material initial sieve position distribution uneven, directly affect grain cleaning effect and cleaning efficiency.
Utility model content
The purpose of this utility model is to provide a kind of simple in construction, cleans united reaper two fans cleaning plant effective, that cleaning efficiency is high.
This utility model is achieved by the following technical programs:
A kind of united reaper two fans cleaning plant, including being arranged on the vibrosieve of frame underside, main air blower, secondary blower fan and two fans driving mechanism; Main air blower and secondary blower fan are separately positioned on front side of vibrosieve, and the two is respectively supported in frame, and main air blower is arranged on frame underside, and main air blower air outlet is corresponding with sieve position under vibrosieve top sieve and vibrosieve respectively; Secondary blower fan is arranged on the upside of main air blower, and secondary fan outlet is corresponding with vibrosieve corrugated plating position; Two fans driving mechanism is arranged on inside frame.
The purpose of this utility model can also be realized further by techniques below measure.
Aforesaid united reaper two fans cleaning plant, wherein said two fans driving mechanism includes the first belt wheel, the second belt wheel and the 3rd belt wheel; First belt wheel is fixed on main air blower power shaft external part, and the first belt wheel is connected with engine output shaft upper belt-wheel by belt; Second belt wheel is fixed on outside the first belt wheel, and the 3rd belt wheel is fixed on secondary blower fan input shaft external part, and the second belt wheel and the 3rd belt wheel are connected by belt.
Aforesaid united reaper two fans cleaning plant, wherein said main air blower is vane type blower fan.
Aforesaid united reaper two fans cleaning plant, wherein said secondary blower fan is vane type blower fan.
Aforesaid united reaper two fans cleaning plant, wherein said main air blower and secondary blower fan are supported in frame respectively through respective power shaft.
This utility model arranges two fans, simple in construction on front side of vibrating screen of harvester, and cost is low, takes up room little. When cleaning corn, from the wind of secondary blower fan to corrugated plating, corrugated plating front portion wind speed is big, and wind flow is big so that corn initial sieve position distribution on corrugated plating is uniform, corn thus can carry out precleaning, reduce top sieve cleaning load, clean effective. It is simultaneously from the wind of main air blower to top sieve and lower sieve, it is ensured that corn efficiently separates, and grain loss is little, and cleaning efficiency is high. Main air blower and secondary blower fan are vane type blower fan, and the two air outlet place wind-force is big, and wind speed is uniform, can be further ensured that and clean effect.
Advantage of the present utility model and feature, by for illustration and explanation by the non-limitative illustration of preferred embodiment below, these embodiments, it is only used as example with reference to accompanying drawing and provides.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
