Abstract
The invention discloses a secondary impurity cleaning device which comprises a secondary impurity cleaning screen, a secondary impurity cleaning screen frame, a connecting supporting plate and a zigzag guiding plate, wherein the secondary impurity cleaning device is arranged between an upper screen and an impurity auger discharging hole. The secondary impurity cleaning device has a novel and simple structure, is convenient to disassemble, assemble and adjust, not only prevents the impurity from entering a re-threshing roller and further avoids increase of kernel damage, but also enables the impurity delivered by an impurity auger to be distributed uniformly through the zigzag guiding plate, has certain cleaning capacity, and can effectively achieve the functions of cleaning, sorting and screening.
Description
Technical field
The present invention relates to a kind of secondary impurity cleaning device of harvest machinery, be mainly used in the assorted remaining screening of the secondary of the various crop such as paddy rice, wheat, barley, rape and uniform.
Background technology
When full feeding rice, wheat, oily combine operation, mixture through compositions such as threshing cylinder threshing the grain seed of separating from concave grate, broken stem stalk and clever shells enters shaking shoe, makes a seed from mixture, separate and enter the seed screw feeder being positioned under vibratory sieve and send into collection tanker under blower fan and vibratory sieve effect.But also some is not completely by threshing and be also pulled to the latter half of and tail sheet of vibratory sieve with disconnected fringe, short stem, blade of grass and the seed of ripe seed and fall.If they enter collection tanker after entering seed screw feeder, will make seed cleannes decline, seed percentage of impurity improves.Therefore, at the rear portion of combine seed screw feeder, operated by rotary motion is collected the tailing auger of small ear and short stem etc., more than assorted, collect and carries.At present to collect assorted more than have two kinds of processing modes, one is to enter rethreshing device more than assorted to carry out secondary threshing, enter sorting screen by separating notch board, again clean operation, this mode complicated structure, and seed secondary enters threshing cylinder the stricken number of times of seed is increased, and causes seed damage to increase.Another kind of mode is assorted remaining directly spraying to be carried out to secondary on top sieve compass screen surface clean, and owing to directly spraying and making material skewness on compass screen surface, thereby can reduce sorting performance.
Summary of the invention
The object of the invention is to, for the deficiencies in the prior art, proposed a kind of secondary impurity cleaning device of combined harvester, improve the sorting performance of combined harvester.
Technical problem to be solved by this invention realizes by the following technical solutions.
A kind of secondary impurity cleaning device, comprises the assorted remaining sorting screen of secondary, the assorted remaining sorting screen screen frame of secondary, connects gripper shoe and zigzag guide plate; The assorted remaining sorting screen screen frame of described secondary is rectangle frame, and described connection gripper shoe is low early and high after trapezoidal plate, and the assorted remaining sorting screen screen frame of described secondary connects B by two connection gripper shoes with bolt and is fixed on main screen frame; The assorted remaining sorting screen of described secondary is fixed on the assorted remaining sorting screen screen frame of secondary, and the assorted remaining sorting screen of secondary is positioned under tailing auger outlet; Above the compass screen surface of the assorted remaining sorting screen of secondary, three zigzag guide plates that form an angle with screen frame being installed, compass screen surface broad ways is divided into four parts, is 50%-75% of the assorted remaining sorting screen cover surface of secondary away from a area of tailing auger outlet; Described zigzag guide plate connects C with bolt and is fixed on the assorted remaining sorting screen screen frame of secondary.
One end that plate hight is supported in described connection is provided with five adjustment connecting holes, and the assorted remaining sorting screen screen frame of secondary is by adjusting the assorted remaining sorting screen of installation site change secondary of connecting bolt with respect to the inclination angle of top sieve.
The assorted remaining sorting screen of described secondary is selected wire gauze sieve, stamped sieve, lip(ped) sieve, wave-shape board or dull and stereotyped as compass screen surface.
The invention has the beneficial effects as follows: this device can make that tailing auger transports assorted is remainingly uniformly distributed it by the effect of zigzag guide plate, and has certain ability of cleaning, and can effectively improve and clean sieve performance.Meanwhile, can avoid entering more than assorted the seed damage that re-threshing roller causes increases.In addition, can adapt to the secondary of various crop and clean more than assorted by regulating the assorted remaining sorting screen of secondary with respect to the inclination angle of top sieve and changing compass screen surface pattern.This apparatus structure novelty, simple, dismounting is easy to adjust, can effectively improve the sorting performance of combined harvester.
