During adjustment, the nut on the middle adjusting wire rod 540 is loosened, the adjusting wire is lifted upwards, the gap is reduced, and the adjusting wire is adjusted downwards, and the gap is increased. The regulation principle is that the clearance is enlarged as much as possible on the premise of threshing cleanly.

Preferably, the separation drum 570 is an open drum.

The axial flow separation roller is an open type roller, which is matched with a complementary threshing concave plate below, and can be used for threshing and separating the threshed objects sent by the tangential flow threshing roller, thereby enhancing the threshing performance and improving the threshing rate. The axial flow divided drum is uniformly distributed with 4 rows of rod teeth at the circumference, which are matched with the separation concave plate to separate the separated objects.

Throw away board and distribution screw feeder: the throwing plate is positioned below the threshing concave plate and is used for throwing grains and chaffs separated from the threshed materials which are cut and separated from the roller by the threshing concave plate onto the shaking plate at the front end of the screen box. The function of the distribution auger is to convey the separated material in the threshing chamber to the right onto a shaking plate at the front end of the screen box.

The cleaning part is positioned behind the threshing part and consists of a screen box, a screen box driving mechanism, a fan and the like. The function is to separate and clean the separated materials to obtain clean grains.

The screen box is a main working part for removing sundries in the grains. The vibrating separation system is composed of a screen box shell, a shaking plate, an upper screen, a lower screen, an upper sliding plate, a lower sliding plate and the like.

The shaking plate is welded with the screen box body and vibrates in a reciprocating manner along with the screen box, and the stepped plate, the straw-pushing plate and the finger-shaped grid bars on the shaking plate are used for conveying and primarily separating materials from the roller, so that the materials form a material curtain with layered grains and chaffs and basically uniform thickness before falling into the screen. The finger bars of the progressive plate are not allowed to be curled and deformed so as not to affect the screening effect.

(1) Upper and lower screens

The upper sieve and the lower sieve in the sieve box are both adjustable fish-scale sieves which are respectively adjusted by two adjusting handles, and the opening degree of the sieve sheet is 0-45. To meet the operating requirements. The upper sieve is composed of 24 rows of fish scale sieve sheets, and two adjusting handles are arranged to respectively control the opening of the sieve sheets at the front end and the rear end. The lower sieve is a grain sieve formed by 27 rows of small fish scale sieve sheets, and two adjusting handles are used for controlling the opening degree.

(2) Sieve sheet aperture adjustment principle:

the opening adjustment of the sieve sheets is matched with the adjustment of the fan, the organic combination and the advantage complementation are realized, the purposes of less grain loss and low grain impurity content of a grain bin are achieved, and the basic adjustment principle is as follows:

(1) sieving: on the premise that the grain impurity rate of grains in the grain bin is not higher than 2%, the opening degree is as large as possible, the opening degree is not smaller than 2/3 of the opening degree when large grains or moist crops with more weeds are harvested, and the opening degree of the front end is slightly smaller than that of the rear end.

(2) Sieving: the lower sieve has larger influence on the cleaning quality, and is generally suitable for smaller opening, if the upper sieve is opened by 2/3, the lower sieve can be opened by 1/2, and the opening of the fish phosphorus sieve sheet is correspondingly reduced along with the opening of the upper sieve, and the opening of the fish phosphorus sieve sheet refers to the vertical distance between the sieve sheets. Under different field operation conditions, the satisfactory cleaning quality can be achieved by trial cutting and adjustment by applying the principle.

The upper and lower fish-scale sieves are required to be cleaned in shift during operation, and the blockage of awns and stalk sundries between sieve sheets is often observed and is cleaned in time so as to ensure a better airflow channel and a better screening area.

When the upper sieve and the lower sieve are installed in the sieve box, the sieve frame must be aligned to the upper sieve slideway and the lower sieve slideway, and after the sieve is pushed in, the weight must be tightly pressed, and the bolts and the nuts are locked.

The barn assembly 400 is a storage area for ears. After the granary is full, the grain unloading handle is operated by a manipulator, so that the grain unloading auger can rotate outwards to a proper position to unload grains. Because the granary is reasonable in design, the grain can be unloaded to a common motor tricycle, a five-wheel tractor and an automobile, and the grain can also be directly unloaded to the ground, so that the granary is simple and convenient.

The cab assembly 200 includes a steering gear control assembly, a hydraulic operating system, a gear shift operating system, a rotary ladder, a throttle control, a brake system, a main clutch operating system, a cab, etc. The driving platform is a place where the manipulator works, and the manipulator can operate all systems to complete all work of the soybean harvester, so that continuous operation is realized.

In summary, the present invention is only a preferred embodiment, and is not intended to limit the scope of the present invention, and various changes and modifications can be made by workers in the light of the above description without departing from the technical spirit of the present invention. The technical scope of the present invention is not limited to the content of the specification, and all equivalent changes and modifications in the shape, structure, characteristics and spirit described in the scope of the claims of the present invention are included in the scope of the claims of the present invention.
