Abstract
The invention discloses a corrugated plate and upper sieve device of a vibrating screen of a harvester. The corrugated plate and upper sieve device is characterized in that the corrugated plate adopts a step-shaped structure; the rear end of an upper corrugated plate and the front end of a lower corrugated plate are connected through a vertical step to form an integral body; a plurality of scalelike toothed plates on the upper sieve are divided into a first scalelike toothed plates combination and a second scalelike toothed plate combination which are adjacent with each other; the two ends of the first scalelike toothed plate combination are hinged to an upper longitudinal connecting rod and a first lower longitudinal connecting rod; the two ends of the second scalelike toothed plate combination are hinged to the upper longitudinal connecting rod and a second lower longitudinal connecting rod; a first scalelike toothed plate angle adjusting plate and a second scalelike toothed plate angle adjusting plate are positioned on one side in the longitudinal direction of a sieving box frame respectively. According to the corrugated plate and upper sieve device of the vibrating screen of the harvester, provided by the invention, the fluffing and separating functions of the corrugated plate for straws and grass are strengthened, and the first scalelike toothed plate combination and the second scalelike toothed plate combination are enabled to have different opening degrees, so that the cleanliness of grains after sieving through the vibrating screen is improved, and loss caused by scattering during harvesting can be reduced.
Description
Technical field
The present invention relates to a kind of vibrating screen device of grain header harvesting grain, especially a kind of have straw grass shake up very well and the corrugated plating of centrifugation, also relate to the upper screen device that can regulate the different gradient of the fish scale tooth plate of top sieve front and back end according to seed cleannes, belong to agricultural machinery technological field.
Background technology
The longitudinal axial flow vibratory sieve front end of grain header is provided with the upper corrugated plating of shaking up with being separated straw grass, and rear end is provided with top sieve, is provided with the fish scale tooth plate that many rows tilt in top sieve, and upper corrugated plating and top sieve are used for initial gross separation straw grass and seed.Existing corrugated plating is the structure of monoblock dull and stereotyped projection many rows ripple, and during harvesting, the straw grass that major part is not separated seed drops on corrugated plating, its shake up be separated straw grass to clean effect undesirable, and the amount of shedding increases.Corrugated plating has straw grass shakes up and centrifugation very well.After the angle of inclination of fish scale tooth plate regulates, be fixed in screening box-frame, if when more namely aperture is large at the angle of inclination of fish scale tooth plate, after guiding air-flow to blow down the straw grass on top sieve and the light impurity in seed, heavier seed and heavy seeds fall on lower compass screen surface and do further sorting.Good, the upper compass screen surface of performance of fish scale tooth plate dispatch heavy seeds or large impurity not easily blocks, productivity ratio is high, and the impurity fallen on lower compass screen surface is more, decreases although shed, but grain is unclean; If the less i.e. aperture hour in the angle of inclination of fish scale tooth plate, although grain is clean, top sieve face easily blocks, productivity ratio is low.Because the aperture of fish scale tooth plate in rear portion in face of top sieve is consistent, be difficult to meet cleaning of the inconsistent grain of seed cleannes.
Summary of the invention
The object of this invention is to provide the corrugated plating of the vibrating screen of harvester that a kind of structure is simple, seed cleaning is effective and upper screen device.
The present invention is achieved by the following technical programs:
The corrugated plating of vibrating screen of harvester and a upper screen device, described corrugated plating and top sieve lay respectively in the longitudinal two ends of screen box; Corrugated plating is terraced structure, comprises the upper corrugated plating and lower corrugated plating that be arranged in parallel, the corrugated teeth that described upper corrugated plating is laterally parallel with the uniform many rows of lower corrugated plating, and upper corrugated plating rear end and lower corrugated plating front end connect into entirety by perpendicular steps; Many fish scale tooth plates of horizontal parallel oblique arrangement are provided with in top sieve, described many fish scale tooth plates are divided into the first adjacent fish scale tooth plate combination and the combination of the second fish scale tooth plate, the upper longitudinal connecting rod and tandem first time longitudinal connecting rod, the second time longitudinal connecting rod that are positioned at fish scale tooth plate combination two ends be arranged in parallel up and down, first fish scale tooth plate combination two ends are hinged with upper longitudinal connecting rod, first time longitudinal connecting rod respectively, and the second fish scale tooth plate combination two ends are hinged with upper longitudinal connecting rod, second time longitudinal connecting rod respectively.
