Background

China is a big agricultural country, and socioeconomic 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, is used as a compound agricultural field operation machine widely applied to crop harvesting, can complete operations of cutting, conveying, threshing, separating, cleaning, collecting and the like of harvested crops at one time, and has the characteristics of high operation efficiency, strong maneuverability and the like.

When the combine harvester works, sometimes the conveying trough of the combine harvester is blocked due to too large feeding amount because of too fast speed or dense crop planting. The conveying trough is required to be reversed after being blocked, and the grass grains which are blocked are discharged, so that continuous operation is ensured. However, in the prior art, most harvesters adopt differential shaft transmission, that is, forward and reverse rotation of the harvester can be switched only by matching the forward rotating shaft and the reverse rotating shaft, and the phenomenon of mutual interference between the forward rotation and the reverse rotation is very easy to occur in practical use.

Therefore, harvesters with single shafts for realizing forward and reverse rotation are available in the market, however, reverse clutches of all cab models are placed outside the cab, which means that when the reverse clutches need to be used, the cab side windows need to be opened to implement reverse operation. Because of reaping the operation environment abominable, dust is more, opens during the side window reversal operation dust just can enter into the driver's cabin often to open along with the air conditioner and flow in the driver's cabin, seriously influence the operation travelling comfort. Meanwhile, the conveying trough utilizes the same transmission mechanism in forward rotation and reverse rotation, which means that forward rotation and reverse rotation can not be performed simultaneously, and if the conveying trough is used simultaneously, the transmission part is damaged or the belt is burnt.

Chinese patent application No.: CN201920150340.0, application date: 29.01 month 2019, the name of the utility model is: an anti-blocking reversing system for a header of a corn harvester capable of harvesting ears and stalks is disclosed in the application and comprises a main power gear box; a main shaft; a forward bevel gear; a reverse bevel gear; the header shaft is rotatably arranged on the main power gear box; a cutting table bevel gear; a sliding sleeve; rotating the block; the reversing shifting fork is rotatably arranged on the rotating block and is in sliding fit with the sliding sleeve; the arc block is fixedly arranged at the free end of the reversing shifting fork; a slideway; a forward and reverse slide block; a cylinder; and the control shaft is hinged with the rotating block and is used for controlling the rotating block to rotate.

This patent adopts the different shaft transmission, and it need just can realize through corotation separation and reunion and reversal separation and reunion structure cooperation simultaneously in the switching of just reversing, therefore the phenomenon that appears just reversing and interfere with each other causes the harvester to take place to damage easily.
