Technical Field
The utility model relates to a single-shaft double-sided transmission shredding and threshing roller, and belongs to the technical field of self-propelled corn kernel combine harvesters.
Background
At present, the self-propelled corn kernel combine harvester in China is mostly modified based on a rice-wheat combine harvester, and the direct harvesting of corn kernels is realized by changing different parts such as a header, a threshing cylinder and the like on the basis of the rice-wheat combine harvester. The threshing roller and the chopper of the threshing machine used by the self-propelled corn kernel combine harvester are separately arranged and hung outside the threshing chamber, so that the threshing machine occupies space, has a complex structure, has limited space for the self-propelled corn kernel and straw combine harvester, and is difficult to install. If the threshing roller and the chopper are arranged on the same transmission shaft (for example, the threshing chopper of Chinese patent CN 2008200963451), the occupied space can be reduced, however, the threshing roller and the chopper of the corn thresher have different rotating speed requirements, the chopper needs to rotate at high speed, and if the rotating speed of the chopper is the same as that of the threshing roller, the chopper is blocked, and the chopping effect is affected.

a single-shaft double-sided transmission shredding and threshing roller comprises a threshing roller and a shredder, and is characterized in that: the threshing roller and the chopper are arranged on the same axis, and the rotating shafts of the threshing roller and the chopper respectively and independently rotate. The threshing roller and the chopper are arranged on the same axis, so that the occupied space is reduced, the threshing roller and the chopper are convenient to install on the self-propelled corn kernel combine harvester, meanwhile, the rotating shafts of the threshing roller and the chopper are respectively and independently rotated, the chopper is rotated at a high speed, the blockage is avoided, and the chopping effect is not influenced.
Further, the rotating shafts of the threshing roller and the shredder are the same shaft, and the threshing roller bearing and the shredder bearing are respectively arranged at the middle disconnection part of the shaft, so that a single-shaft double-sided transmission shredding threshing roller structure is formed.
Further, a threshing roller wheel is arranged at the end part of a transmission shaft of the threshing roller, and the threshing roller wheel is connected with an output wheel of the driving box; the end part of the transmission shaft of the chopper is provided with a chopper wheel which is connected with the output wheel of the driving box; the threshing roller and the chopper share the same driving box output wheel and share the same power source.
Further, the outer diameter of the threshing roller wheel is larger than that of the chopper wheel, the threshing roller wheel and the chopper wheel are respectively matched with the same driving box output wheel, and the rotating speed of the chopper is higher than that of the threshing roller.
Further, the driving box output wheel is connected with the intermediate shaft input wheel through a first belt, the intermediate shaft input wheel is connected with the intermediate shaft output wheel through two intermediate shafts and a coupling, and the intermediate shaft output wheel is connected with the chopper wheel through a second belt.
Further, the driving box output wheel is connected with the threshing roller wheel through a belt III.
