Description
Technical Field
The invention relates to the technical field of harvesters, in particular to an anti-blocking grass and grass returning middle conveying device of a harvester.
Background
The combine harvester is a machine integrating the harvester and the thresher with an intermediate conveying device, and can complete cutting, threshing, separating, cleaning and other operations in one step in the field to directly obtain clean grains, so that the production efficiency is high. With the continuous improvement of agricultural mechanization degree in China, the specific gravity of the combine harvester in the harvesting operation is necessarily increased gradually. In many industrially developed countries abroad, grain harvesting is accomplished by combine harvesters.
The whole-feed harvester feeds all the grain stalks and spikes into a threshing device for threshing. The grain is fed from one end of the roller shaft and makes spiral motion along the axial direction of the roller, while threshing and separating. It takes a long time to pass through the drum and is finally discharged from the other end of the drum shaft. The type can save a huge straw shaker in the combine harvester, reduce the volume of the combine harvester and the weight of the combine harvester, and can be commonly used for various crops such as soybean, corn, wheat, rice and the like.
The middle conveying device is used for conveying the ear stalks conveyed by the header into the threshing device and is of a chain rake type, a belt rake type, a rotating wheel type and the like.
The chain harrow type conveying device is reliable in work, can realize continuous and uniform feeding, is widely applied, and consists of a conveying groove with a rectangular cross section and an annular chain with a scraper, wherein a driven wheel shaft at the lower end of the chain can float up and down to adapt to the thickness change of a fed crop layer and prevent blockage, and the speed of the chain is 3-5 m/s.
The harrow-type conveying device replaces an annular chain with an annular rubber belt or a canvas belt with harrow teeth, the harrow-type conveying device is simple in structure, the conveying belt is easy to slip, and the conveying speed is 2-4 m/s.
The runner type conveying device is composed of a conveying groove and a plurality of runners with blades or toothed bars, the linear speed of each runner is about 10-15 m/s, and the speed of each runner is gradually increased from bottom to top.
In the middle of the existing full-feeding harvesting machinery conveying device, two using modes are mainly adopted:
1. chain-rake conveyor: the chain scraper consists of a driving chain wheel, a driven roller or chain wheel, an L-shaped or U-shaped plate scraper arranged on a sleeve roller chain, a conveying groove and the like.
2. A belt rake conveyor: consists of a driving wheel, a driven wheel, a long conveying groove and a flat adhesive tape or a rubber canvas belt provided with an L-shaped toothed plate. The structure of the conveyer belt is determined according to the size of the random type, the medium-sized machine adopts a specially-made wide adhesive tape, the small-sized machine adopts a canvas belt, and two sides of the bottom of the small-sized machine are respectively inlaid with a common adhesive tape so as to increase the strength of the canvas.
The shape and structure of the rake teeth of the conveying chain (belt) directly influence the conveying effect. When the conveying chain (belt) is tensioned, the gap between the rake teeth and the bottom plate is large, at the moment, the L-shaped or U-shaped plate scraper cannot stretch into the crop straws but only acts on the surfaces of the crop straws, the crop straws entering the groove from the notch are slightly small under the action of the L-shaped or U-shaped plate scraper, the crops at the bottom move only by other crop hanging belts, the conveying is not thorough, the time is long, the number of accumulated crops at the bottom of the groove is increased, the blockage can be caused, and the conveying chain (belt) and the V-shaped transmission belt are easy to damage.
