Walking power output mechanism of combine-harvester

Abstract

The invention belongs to the technical field of agricultural equipment, and provides a walking power output mechanism of a combine-harvester. The walking power output mechanism comprises a power input end assembly, an output shaft, a driving gear assembly and a crawler wheel assembly, a sleeve part is arranged on the exterior of the output shaft between the crawler wheel assembly and the driving gear assembly, the output shaft is arranged in the sleeve part in a penetrating mode, and an axial coordination assembly used for adjusting the running clearance distance is arranged between the output shaft and the sleeve part. The walking power output mechanism has the advantages that by means of the axial coordination assembly, it is guaranteed that the caterpillar drive structure is stable and is not likely to fail or damage, the maintenance cost can be reduced, the running speed of the combine-harvester on a smooth-riding surface is increased, and adaptability to complex field blocks is improved, and the cross-regional operation property of the combine-harvester is greatly improved; meanwhile, a longitudinal adjusting bearing, a first rolling bearing and a second rolling bearing can prolong the abrasion life by adjusting the clearance matched with the output shaft, the service life is further prolonged, and the reliability is further improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural equipment and relates to a combine harvester, in particular to a walking power output mechanism of the combine harvester. Background technique [0002] Agricultural machinery refers to various machinery used in crop planting and animal husbandry production, as well as in the primary processing and handling of agricultural and animal products. Agricultural machinery also includes crop harvesting machinery, agricultural transport machinery, etc. At present, driven by factors such as national policy guidance and the transfer of rural labor force, the speed of domestic land transfer has accelerated, the area of ​​a single plot has increased, the roads for machine farming have become wider, and the yield per mu of crops has continued to increase. Users have higher and higher requirements on the working efficiency of combine harvesters. On the other hand, users have higher and higher requirements...

On the other hand, users have higher and higher requirements for the return on investment of combine harvesters, and the harvest of single-season crops can no longer meet the user's income requirements

[0003] The walking power output mechanism of the combine harvester here is mainly used to realize the walking, braking and steering of the entire combine harvester by driving the crawler belt, but there are currently big problems due to the unreasonable mechanism of the entire walking power output mechanism. When one side When the track brakes, the walking power output mechanism drives it to produce complete sliding friction against the ground when turning, which seriously damages the soil of the paddy field. When it turns, the track on the braking side will cause soil accumulation, resulting in difficulty in turning. And lead to insufficient fuel combustion. At the same time, due to the demand for combine harvesters in the market, under the same chassis aspect ratio, increasing the weight of the whole machine will make steering more difficult. Once the load increases, the resistance of one side of the track increases. It will cause the engine to stall. At the same time, the existing walking power output mechanism still has the disadvantages of difficulty in walking on wet and soft fields and uneven ground, easy to sink, and poor adaptability.
