Self-propelled silage harvester

Abstract

The invention provides a self-propelled silage harvester. The self-propelled silage harvester comprises a feeding device assembly, a header, a cutting device assembly, a transition cylinder assembly,a seed crusher assembly, a power system, a walking system, a rack, a fuel tank, a rear steering axle, a grass collecting box, a hydraulic system, an automatic knife grinding device, a cab, an operating platform assembly, an auxiliary throwing device, a throwing cylinder and the like. Modular design is adopted for all the working parts, quick hooking structures are adopted among the parts, and assembly, maintenance, repairing and adjustment are very convenient. In the meanwhile, the header can be replaced with a picking header or a mowing header, and one machine has multiple purposes. By meansof the self-propelled silage harvester, the bottleneck problems that an existing small-sized self-propelled silage machine is low in efficiency and poor in silage quality are solved; a secondary heightening technology is adopted for a grain tank, the capacity of the grass collecting box is larger, the grain unloading height is larger, the practicability is higher, and the problems that a grain tank of the small-sized silage machine is small in capacity and grain unloading height, and unpractical are solved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a self-propelled green fodder harvester. Background technique [0002] At present, due to terrain and other factors in my country, there are still large areas with small plots. Due to the small plots and narrow roads, large-scale forage harvesters cannot be used for operations, or large-scale forage harvesters are used for operations, which is inefficient and economical. At the same time, due to the structural limitations of the small green fodder harvesters in the current market, the basic structural form basically adopts a multi-functional header, that is, the header integrates the functions of cutting, feeding, chopping, kneading, and throwing. Due to the limited space and too many integrated functions of the header, the efficiency is low and the chopping quality is not high, and the throwing cylinder is in front of the cab, which affects the driver's sight.

Problems solved by technology

[0005] ① The chopping chamber is a fixed structure, while the feeding device is a rotatable structure, which will cause the distance between the feeding roller and the chopping roller close to the chopping roller to increase with the rotation of the feeding device, resulting in The clamping force on the material is small, which affects the chopping quality, and the material is loose due to the small clamping force, which will cause excessive power loss;

[0006] ②The number of feeding rollers is large and the diameter is small. When harvesting corn, the corn stalks are hard and the flexibility is poor. The above results will not cause problems. Feed rollers are entangled with grass due to being less than the height of the crops;

[0007] ③It takes up a lot of space. The channel between the chopping roller and the ejector of the above patent is a horizontal channel, which occupies a large space of the whole machine. In addition, the grass collecting box is placed on the upper part of the fuel tank, and the fuel tank is placed on the lower part. The space is not fully utilized. The volume of the grass collection box is too small, and the practicability becomes poor;

[0009] ⑤ In different regions and when feeding different livestock, the required feed lengths are different, and the above-mentioned patents are not equipped with a length adjustment function, so the adaptability is relatively poor;

[0010] ⑥ Due to the particularity of the operation of the green feeding machine, if it is blocked when feeding too much, it is very inconvenient to clean up, the workload is heavy, and the efficiency is affected. The above-mentioned patent is not equipped with the reverse anti-ejection function;

[0011] ⑦When the chopping hob works for a period of time or foreign matter enters it, the blade will be chipped or blunt, which will seriously affect the chopping quality of the feed. At this time, it is necessary to sharpen the knife to keep the knife sharp, but the above patent does not mention the automatic sharpening configuration ;

[0012] ⑧The power transmission of the above-mentioned patents is relatively complicated. The power transmission is first transmitted from the engine to the first intermediate shaft, then from the first intermediate shaft to the second intermediate shaft, and then from the second intermediate shaft to the header intermediate shaft, chopping roller, and throwing device
