Description
Technical field
The utility model relates to the field of structural design of the shredding mechanism of corn picker more particularly to a kind of corn to gather in
Shredding mechanism before machine stalk.
Background technique
When corn picker gathers in, the stalk that the ceding of Taiwan leaves after gathering in corn ear may be overwhelmed by front tyre, be caused
The straw chopping that corn picker can not will overwhelm, field effect is bad, therefore, generally flail knife group can be arranged in the lower section of the ceding of Taiwan
Part, by flail knife component by straw chopping.
But the flail knife component of the prior art is directly to be driven by the power device of harvester, the revolving speed of flail knife component compared with
Slowly, so that the chopping result to stalk is bad.
Summary of the invention
The purpose of the utility model is to provide shredding mechanisms before a kind of corn picker stalk, improve turning for flail knife component
Speed improves the chopping result to stalk.
The technical scheme that the utility model is provided is as follows:
Shredding mechanism before a kind of corn picker stalk, comprising: the first transmission group, first transmission group include that setting exists
