Small efficient combine harvester

Abstract

The invention discloses a small efficient combined harvester which comprises a traveling assembly, an engine assembly, a header assembly, a threshing assembly, a discharge drum assembly, a gearbox assembly and a transmission control assembly. The header assembly comprises a framework, reel components, an upper cutter component, grain lifters, a conveying roller and a support part, the framework is hinged to the front end of the traveling assembly, the reel components, the upper cutter component, the grain lifters, the conveying roller and the support part are mounted on the framework, and the conveying roller is arranged on the rear side of the upper cutter component and is used for longitudinally conveying cut seedling panicles to the threshing assembly along the harvester. The small efficient combined harvester has the advantages that the seedling panicles do not need to be transversely conveyed and are prevented from being transversely accumulated, the small efficient combined harvester is high in conveying capacity within unit time, is simple in structure, low in self weight and idle resistance, and can perform harvesting operation at a high advancing speed as compared with an existing small combined harvester, the harvesting efficiency can be greatly improved, the labor intensity of grain harvesting personnel, the grain harvesting cost and grain harvesting time consumption can be further reduced, and human resources are saved.

Description

technical field [0001] The invention relates to a grain harvesting machine, in particular to a small high-efficiency combine harvester. Background technique [0002] The combine harvester is a harvesting machine that can complete the harvesting, threshing, and debris removal of cereal crops at one time, and then directly obtain grain from the field. Compared with manual harvesting, it can reduce threshing losses, reduce labor intensity, and save labor. It is a field operation. Indispensable agricultural machinery. [0003] At present, there are small combine harvesters on the market, which are cheap, flexible and convenient to move, and are suitable for harvesting operations in small fields. The front end of the walking car body is used for harvesting seedlings; the conveying device is usually set between the header and the threshing assembly to form a bridge for transporting the seedlings to the threshing assembly, linking harvesting and threshing together in an orderly ma...

Problems solved by technology

In the prior art, the harvesting width of small and medium-sized combine harvesters is usually designed to correspond to the width of at least two field ridges, so that at least two ridges of grain can be harvested in one trip. Therefore, the conveying device also widely adopts the structure combining the horizontal spiral auger and the conveying chain. , through the horizontal auger, the cut seedlings are concentrated horizontally at the entrance of the conveying chain, and then the conveying chain is used to transport the seedlings longitudinally to the threshing assembly for threshing. The resistance is relatively large, so the width of the conveyor chain is generally controlled within 30 cm to prevent its own weight and idling resistance from being too large, and to ensure the dynamic performance of the small combine harvester, but at the same time it also greatly limits the conveying capacity of the conveyor chain and efficiency, the speed of the combine harvester needs to be strictly controlled during the harvesting operation, resulting in the generally low harvesting efficiency of the existing small combine harvesters
