Grain harvesting machine with good power performance

Abstract

The invention discloses a grain harvesting machine with good power performance. The grain harvesting machine comprises a self-propelled machine body, a harvester, a spiral conveying device and a drum-type threshing device, wherein the harvester, the spiral conveying device and the drum-type threshing device are arranged on the self-propelled machine body; the self-propelled machine body comprises a frame, traveling wheels, an engine and a transmission component; the transmission component is in transmission connection to the power output shaft of the engine, the harvester, the spiral conveying device, the threshing device and the traveling wheels and comprises a side-hanging-type transmission box which is transversely arranged on the lateral side of the frame and is used for transmitting power to the traveling wheels; the flywheel of the engine comprises a flywheel body, at least two variable-inertia sliders and an internal balance rotary disc; the variable-inertia sliders are uniformly arranged around the rotary shaft of the flywheel body and are radially and slidably connected to the flywheel body; the internal balance rotary disc serving as a synchronizing device is coaxially and rotatably connected with the flywheel body and is in slide fit with the variable-inertia sliders through a planar slideway; the planar slideway deflects along the circumferential direction of the rotary disc, so that a certain included angle is formed between the planar slideway and the sliding direction of the corresponding slider. The grain harvesting machine with good power performance has the advantages that the engine, the harvester, the threshing device and the spiral conveying device are compactly distributed, so that the operating flexibility of the whole harvesting machine can be improved, the length of a transmission chain is reduced, the stability of a transmission structure is ensured, the grain harvesting machine is less prone to failure and damage, and maintenance cost is reduced favorably.

Description

technical field [0001] The invention relates to a harvesting machine, in particular to a grain harvesting machine with good power performance. Background technique [0002] The combine harvester is a harvesting machine that can complete the harvesting, threshing, and removal of sundries of cereal crops at one time, and obtain grains directly from the field. Compared with manual harvesting, it can reduce threshing losses, reduce labor intensity, and save labor. It is indispensable for field operations. of agricultural machinery. [0003] At present, there are combine harvesters on the market, which have high production efficiency and low price, and are suitable for harvesting operations in small fields. They are generally composed of self-propelled car body, harvesting device, threshing device and screw conveying device. And the road wheels, engine and power transmission box installed on the vehicle frame. In the prior art, the power transmission box, engine, harvesting devi...

Problems solved by technology

[0003] At present, there are combine harvesters on the market, which have high production efficiency and low price, and are suitable for harvesting operations in small fields. They are generally composed of self-propelled car body, harvesting device, threshing device and screw conveying device. And the road wheels, engine and power transmission box installed on the vehicle frame. In the prior art, the power transmission box, engine, harvesting device, threshing device and screw conveying device are arranged vertically on the vehicle frame, and the overall longitudinal length of the harvester is relatively long. , the flexibility of manipulation is slightly poor, the transmission chain is long, the transmission parts are scattered, the structure is not compact, the reliability of belt transmission is poor, it is easy to fail and damage, and the maintenance cost is high
