Technical Field

The invention belongs to the field of a combine harvester and a transmission device thereof, and relates to a combine harvester conveying trough driving device and a combine harvester.

Background

China is a big agricultural country, and socioeconomic performance has high requirements on the harvest quality and efficiency in grain production. At present, the combine harvester is gradually popularized in agricultural production in China, can be widely applied to crop harvesting compound agricultural field operation machinery, can complete operations such as cutting, conveying, threshing, separating, cleaning and collecting of harvested crops at one time, has the characteristics of high operation efficiency, strong maneuverability and the like, plays an important role in reducing labor intensity of farmers, robbing and harvesting and promoting yield and income increase, is increasingly favored and relied by farmers in agricultural production, and is an indispensable important machine tool in modern agricultural mechanized production.

However, in the operation process, the conveying trough of the combine harvester is easy to be blocked, one of the most common faults is the blockage of the conveying trough, and the blockage is mainly caused by improper operation, overload work in the use process, or forced full-width cutting operation due to the fact that the crop conditions are not suitable for full-width harvesting (such as too high crop, excessive density or humidity and the like). And once blocking, just must shut down to get rid of, clear up through artifical manual work and block up the crop, this not only has the potential safety hazard, wastes time and energy, if frequently takes place, still can seriously influence results efficiency. Therefore, a combine harvester is required to be equipped with a conveying trough driving device with simple structure and excellent function. The blockage can be simply discharged in time, and the working state can be adjusted.

The existing domestic and foreign combine harvesters are equipped with a conveying trough with the functions of forward grass conveying and reverse grass returning. For example, the Chinese invention patent, the grant publication number: CN 102084755B, date of authorized announcement: 2014.10.22 discloses a combine harvester, a transmission case is arranged at the front side of the advancing machine body of a threshing device, a forward rotation clutch and a reverse rotation clutch are arranged, case input shafts are arranged at the left side and the right side of the transmission case in a protruding way, the rotation directions of the two case input shafts are opposite, the forward rotation clutch enables the case input shaft in the forward rotation direction to be linked with a harvesting input shaft, the reverse rotation clutch enables the case input shaft in the reverse rotation direction to be linked with the harvesting input shaft to transmit the driving force in the forward rotation direction and the reverse rotation direction, the functions of forward rotation grass conveying and reverse rotation grass returning of a conveying trough of the combine harvester are realized, but the structure is complex, the requirement on the transmission case is high, and the probability of failure is.

For another example, the chinese patent application No.: 201510020713.9, filing date: 2015.01.16, discloses a transmission mechanism of a combine harvester, which comprises a transmission shaft, a power wheel, a first wheel set driven by the power wheel to rotate positively, a second wheel set driven by the power wheel to rotate negatively, a first transmission belt in transmission connection between the first wheel set and the transmission shaft, a second transmission belt in transmission connection between the second wheel set and the transmission shaft, a first tensioning mechanism for tensioning or relaxing the first transmission belt, and a second tensioning mechanism for tensioning or relaxing the second transmission belt, wherein the power wheel provides driving force for the first wheel set in positive rotation and the second wheel set in reverse rotation simultaneously through a chain, and at the moment, if the chain breaks down, the harvester can not work completely.

Therefore, aiming at the problems, the problem that the conveying trough of the harvester is easy to block, and the forward and reverse rotation transmission mechanism of the conveying trough of the existing harvester is easy to influence the forward rotation conveying function of the conveying trough is of great significance.
