Description
Technical Field
The invention relates to an agricultural machinery throwing device, in particular to a shaking throwing device for grain removal objects in different-direction allocation and uniform spreading modes.
Background
In the grain combine harvesting process, the shaking plate is an important part for connecting the threshing device and the cleaning device, the shaking plate has the functions of collecting grain threshing matters from the threshing device, then feeding the grain threshing matters into the cleaning device through shaking throwing action, the operation performance of the shaking plate determines the material flowing state to a certain extent, and has important influence on the cleaning and impurity removal of subsequent threshing matters, so that the improvement of the operation form of the shaking plate and the improvement of the operation performance of the shaking plate are the key for ensuring the efficient and low-loss cleaning of the threshing matters.
At present, in a domestic and foreign grain combine harvester, a shaking plate is usually arranged below a threshing device, above a cleaning sieve, after a threshed object flows out of the threshing device, the threshed object passes through a guide plate and falls onto the shaking plate at first, the shaking plate throws materials above the cleaning sieve through continuous shaking under the driving of a reciprocating mechanism, and under the cooperation of cleaning air flow, part of impurities with lighter mass are blown out of the harvester, and grains with heavier mass and the like fall onto the cleaning sieve surface. However, when the feeding amount of the harvester is unstable or grain is excessively wet and sticky, the phenomenon of uneven material distribution often occurs on the shaking plate, and as the shaking plate can only longitudinally push materials and does not have the function of transversely uniformly spreading the materials, the materials with uneven thickness fall into the cleaning screen surface through the shaking plate, so that the uneven material distribution on the cleaning screen surface is caused, the effective operation area of the cleaning screen surface cannot be fully utilized, the operation efficiency of the cleaning screen is greatly reduced, particularly, wet sticky materials such as rice, rape and the like are heavy in quality, high in viscosity and easy to agglomerate, the agglomerated materials are difficult to scatter due to the single vibration form of the shaking plate, the materials cannot be thrown to a proper height due to insufficient vibration strength, and the materials are accumulated, so that the important influence is generated on the subsequent cleaning operation.
In view of the technology and performance of the grain shaking and throwing device, there is an urgent need for a grain shaking and throwing device with stable material flow, uniform distribution, strong throwing capacity, high vibration intensity, high operation efficiency and high reliability.
