Detailed Description

The utility model is further described below with reference to examples:

as shown in figures 1-4, the crawler-type corn harvester suitable for mountainous and hilly areas of the utility model,

the corn harvester comprises a snapping header 1, an elevator assembly 2, a peeler assembly 3 and a granary 4 in sequence from front to back, wherein a chassis assembly 6 is arranged below a corn harvester, the elevator assembly 2 penetrates through a cab 5, and a cab is arranged on one side of the elevator assembly 2; the tail end of the elevator assembly 2 is connected with an impurity discharging fan 7, and the side face of the tail end of the elevator assembly 2 is provided with an impurity discharging port 8; the chassis assembly 6 comprises a crawler walking system and a power system.

The chassis part of the utility model comprises a drive axle assembly, an HST, a thrust wheel, a frame, a crawler, a guide wheel and the like. The chassis part is a carrier of the whole corn harvester, integrates all mechanisms on the corn harvester, and bears all the mechanisms to travel together, thereby realizing the advancing speed change and the steering of the machine tool.

The power system comprises an engine, the engine is in bidirectional power output (as shown in figure 4), an output shaft at the rear end of the engine drives a belt pulley to rotate through a main clutch, and the ear picking header 1, the elevator assembly 2 and the peeler assembly 3 work; an output shaft at the front end of the engine drives the crawler traveling system to realize the traveling of the corn harvester. The power part also comprises a main clutch, a radiator, an engine base and an air filter assembly. The bidirectional power output mechanism separates the power of the working part from the power of the walking part, so that the machine tool is convenient to operate, and the transmission mechanism of the machine tool is simple. Particularly, when the main clutch has a large fault and stops working, the unit can still normally run to carry out remote maintenance, which cannot be realized by a harvester with single-side power output.
