Concrete meaning in the utility model.
As shown in Figure 1 and Figure 2, the utility model discloses a kind of two level pneumatic separation device of rape combined harvester, including wind
Case 1 is selected, top, the bottom of the Winnowing box 1 are respectively arranged with charging aperture, discharging opening, cleaning plant；The Winnowing box 1 is relative
Both sides be respectively arranged with wind pushing box 4, go out faucal 5, the wind pushing box 4 is adjustably detachably connected by fixation kit position
In the side of the Winnowing box 1, the cleaning plant is arranged on the air-out direction of the wind pushing box 4.
Charging aperture, discharging opening are engaged with feeding cylinder 2, discharge barrel 3 respectively.Feeding cylinder 2 is in horn-like, thickness 2mm, will
Material after cyclone separating tube is tentatively cleaned is entered in Winnowing box 1 by feeding cylinder 2, and the material after tentatively cleaning contains oil
Vegetable seed grain, Fruit pod shell and a small amount of stalk etc..Discharge barrel 3 is in hollow funnel-form, and funnelform discharge barrel contributes to through wind
Select case clean after rape seed it is quick and stably discharge.
Feeding cylinder 2 is connected with charging aperture by plectrum, and charging aperture is provided with an arc-shaped slot, is provided with feeding cylinder and arc
The corresponding bayonet socket of shape neck, plectrum insertion bayonet socket and stretch into neck, plectrum into and out will control charging aperture it is big
It is small, so as to the amount of feeding of control material.
The position of wind pushing box 4 is adjustably arranged on Winnowing box 1.In this way, the position of wind pushing box can be adjusted as needed,
And then adjust the height and size of air outlet.
As shown in Fig. 1, Fig. 3, Fig. 4, wind pushing box 4 is fixedly connected with fixed seat 44, is provided with fixed seat 44 and wind pushing box 4
The rectangle air outlet 42 being connected, 4 stopper slots 43 are additionally provided with fixed seat 44, screw, screw rod are provided with Winnowing box 1
One end is screwed in screwed hole through stopper slot 43, and wind pushing box is moved up and down by stopper slot 43 along screw rod.When needs change
During the height of air port, screw rod 7 can be unscrewed, fixed seat 44 be moved up or moved down a segment distance, then tighten screw rod 7.
Wind pushing box section is slightly smaller, the less symmetrical eight-sided formation of wind outlet at broad in the middle, air intake, at the structure air intake
Section is slightly smaller, wind enter wind pushing box after be unlikely to gather diffusion cause it is larger turbulent flow and cause energy loss；Whole wind pushing box knot
Structure is advantageous to that blast is relatively stable, air-out is smooth.The side of wind pushing box 4 is connected with air inlet pipe 41, and the position of air inlet pipe 41 is with going out
Air port 42 is relative, and the cross-sectional area of air inlet pipe 41 is 2 times of air outlet 42, and air-flow is by air outlet 42 of the air inlet pipe 41 through wind pushing box
Outflow, forms the air-flow of larger wind speed and flows into Winnowing box 1, is advantageous to improve selection by winnowing effect.Certainly, as needed, air inlet
The cross-sectional area of pipe 41 can also be other multiples of air outlet 42.
Cleaning plant includes at least two sorting screens 6：First the 61, second sieve 62 of sieve, the first sieve are arranged on the upper of the second sieve
Side, one end welding of first the 61, second sieve 62 of sieve are arranged on selection by winnowing chamber interior wall, and the other end is vacantly arranged in Winnowing box, and
First the 61, second sieve of sieve 62 is staggeredly welded on the relative inwall of Winnowing box 1, the horizontal position of the free end of sorting screen than fixing end
Set low, the angle between first the 61, second sieve 62 of sieve and selection by winnowing chamber interior wall is 30 °~60 °.As shown in figure 5, the sorting screen bag
Compass screen surface 63, sieve bottom 64, sieve aperture 65 are included, the compass screen surface, sieve bottom form hollow structure, and the sieve aperture is through the compass screen surface, sieve bottom, institute
State sieve aperture not connect with the hollow structure, the sieve aperture on the compass screen surface is nearby additionally provided with buffering air flue 66, in described
Hollow structure side is provided with air inlet duct 68, and the buffering air flue is connected with the hollow structure, and the air inlet duct includes wind-guiding
Plate 67, the wind deflector and the compass screen surface are into obtuse angle.By wind pushing box feeding Lai air-flow largely directly blow to from charging aperture
The material entered, fraction enter buffering air flue, because stalk proportion is small compared with rape seed, the stalk body of identical weight by wind deflector
Product is bigger than rape seed, big by wind action power, can be obtained by wind it is farther, so the bulky short stem of light weight is in horizontal stroke
Winnowing box is blown from going out faucal 5 in the presence of to air-flow, part rape seed falls into discharging opening via the sieve aperture of sorting screen 6,
Part rape seed is slid to discharging opening via compass screen surface, due to buffering the setting of air flue, the material of entrance will not on compass screen surface shape
Into dense packing, reduce mutual extruding situation of the material in sieve aperture, so as to alleviate the possibility of feed blocking sieve aperture, and
And due to buffering air flue windward power effect, the material entered from charging aperture can seethe with excitement on sorting screen compass screen surface, overturn
Compound movement, it is favorably improved cleaning efficiency.First the 61, second sieve of sieve 62 forms sizing screening, and material enters in the first sorting screen
Row first time wind filter, remove the material such as short stem of the larger lighter weight of volume, material or process sieve aperture or via compass screen surface
The second sorting screen is slipped down to, the impurity of smaller size smaller is removed again, obtains purer rape seed, it is preferable so as to reach
The separating effect of rape seed and stalk.
Angle between sorting screen and selection by winnowing chamber interior wall is 30 °~60 °, and the aperture of sorting screen is 4-6mm.
While there has been shown and described that embodiment of the present utility model, it will be understood by those skilled in the art that：
These embodiments can be carried out with a variety of changes, modification in the case where not departing from principle and objective of the present utility model, replaced
And modification, the scope of the utility model are limited by claim and its equivalent.
