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 assorted surplus cleaning plant of secondary of harvest machinery, be mainly used in the assorted surplus screening of secondary of 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 and the grain seed of separating from concave grate, broken stem stalk and clever shells enters shaking shoe, makes a seed separate and enter the seed screw feeder that is positioned under the vibratory sieve under blower fan and vibratory sieve effect from mixture and sends into the collection tanker.But also some not fully by threshing and the disconnected fringe, short stem, blade of grass and the seed that also have a ripe seed be pulled to the latter half of and tail sheet of vibratory sieve and fall.If enter the collection tanker after they enter the seed screw feeder, the seed cleannes will be descended, the 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., surplusly collects and carries assorted.At present assorted surplus two kinds of processing modes are arranged to what collect, a kind of is that the assorted surplus rethreshing device that enters carries out the secondary threshing, enter sorting screen by separating notch board, clean operation once more, this mode structure more complicated, and the seed secondary enters threshing cylinder makes the stricken number of times of seed increase, and causes the seed damage to increase.Another kind of mode is secondary to be carried out in assorted surplus direct spraying clean on the top sieve compass screen surface, because directly spraying makes material skewness on compass screen surface, thereby can reduce sorting performance.
Summary of the invention
The objective of the invention is to,, proposed a kind of assorted surplus cleaning plant of secondary of combined harvester, improve the sorting performance of combined harvester at the deficiencies in the prior art.
Technical problem to be solved by this invention realizes by the following technical solutions.
A kind of secondary surplus cleaning plant of mixing, comprise secondary mix surplus sorting screen, the assorted surplus sorting screen screen frame of secondary, connect gripper shoe and zigzag guide plate; The assorted surplus sorting screen screen frame of described secondary is a rectangle frame, and described connection gripper shoe is low early and high after trapezoidal plate, and the assorted surplus sorting screen screen frame of described secondary connects gripper shoe by two and is fixed on the main screen frame with bolt connection B; The assorted surplus sorting screen of described secondary is fixed on the assorted surplus sorting screen screen frame of secondary, and the assorted surplus sorting screen of secondary is positioned under the tailing auger outlet; Three zigzag guide plates that form an angle with screen frame being installed above the compass screen surface of the assorted surplus sorting screen of secondary, the compass screen surface broad ways is divided into four parts, is secondary 50%-75% of the surplus sorting screen cover surface of mixing away from a area of tailing auger outlet; Described zigzag guide plate connects C with bolt and is fixed on the assorted surplus sorting screen screen frame of secondary.
One end of described connection support plate hight is provided with five and adjusts connecting holes, and the assorted surplus sorting screen screen frame of secondary passes through to adjust the inclination angle of the assorted surplus sorting screen of installation site change secondary of connecting bolt with respect to top sieve.
The assorted surplus sorting screen of described secondary is selected wire gauze sieve, stamped sieve, lip(ped) sieve, wave plate or dull and stereotyped as compass screen surface for use.
The invention has the beneficial effects as follows: the assorted surplus effect by the zigzag guide plate that this device can make tailing auger transport makes its even distribution, and has certain ability of cleaning, and can effectively improve and clean sieve performance.Simultaneously, can avoid the assorted surplus seed damage increase that re-threshing roller causes that enters.In addition, by regulating the assorted surplus sorting screen of secondary with respect to the inclination angle of top sieve with change assorted surplus the cleaning of secondary that the compass screen surface pattern can adapt to various crop.This apparatus structure novelty, simple, dismounting is easy to adjust, can effectively improve the sorting performance of combined harvester.
